The history of women in engineering predates the development of the profession of engineering. Before engineering was recognized as a formal profession, women with engineering skills often sought recognition as inventors. During the Islamic Golden Period from the 8th century until the 15th century there were many Muslim women who were inventors and engineers, such as the 10th-century astrolabe maker Al-ʻIjliyyah.

In the 19th century, women who performed engineering work often had academic training in mathematics or science, although many of them were still not eligible to graduate with a degree in engineering, such as Ada Lovelace or Hertha Marks Ayrton. Rita de Morais Sarmento was one of the first women in Europe to be certified with an academic degree in engineering in 1896. In the United States at the University of California, Berkeley, however, both Elizabeth Bragg (1876) and Julia Morgan (1894) already had received their bachelor's degree in that field.

In the early years of the 20th century, a few women were admitted to engineering programs, but they were generally looked upon as curiosities by their male counterparts. Alice Perry (1906), Cécile Butticaz (1907), and Elisa Leonida Zamfirescu (1912) and Nina Cameron Graham (1912) were some of the first European to graduate with a degree in engineering. The entry of the United States into World War II created a serious shortage of engineering talent in America as men were drafted into the armed forces. The GE on-the-job engineering training for women with degrees in mathematics and physics, and the Curtiss-Wright Engineering Program had "Curtiss-Wright Cadettes" ("Engineering Cadettes", e.g., Rosella Fenton). The company partnered with Cornell, Penn State, Purdue, the University of Minnesota, the University of Texas, RPI, and Iowa State University to create an engineering curriculum that eventually enrolled over 600 women. The course lasted ten months and focused primarily on aircraft design and production.

Kathleen McNulty (1921–2006), was selected to be one of the original programmers of the ENIAC. Georgia Tech began to admit women engineering students in 1952. The Massachusetts Institute of Technology (MIT) had graduated its first female student, Ellen Swallow Richards (1842–1911), in 1873. The École Polytechnique in Paris first began to admit women students in 1972. The number of BA/BS degrees in engineering awarded to women in the U.S. increased by 45 percent between 1980 and 1994. However, from 1984 to 1994, the number of women graduating with a BA or BS degree in computer science decreased by 23 percent.

The Afghan Girls Robotics Team made history in 2017, following their love of engineering and robotics to take part in the FIRST Global Challenge in Washington DC. Members of the team, aged 12 to 18, overcame war and other hardships in the quest for national pride and as a symbol of a more Progressive Afghanistan. But the overthrowing of the Afghanistan government by the Taliban in August 2021 left the girls on the team fearful for their safety. On 21 August 2021 it was reported that nine Afghan girl robotics team members were safe in Qatar, having made it out of Kabul. The girls on the team were offered scholarships at 'incredible universities' to pursue their careers in robotics and engineering.

Terminology

Although the terms engineer and engineering date from the Middle Ages, they acquired their current meaning and usage only recently in the nineteenth century. Briefly, an engineer is one who uses the principles of engineering – namely acquiring and applying scientific, mathematical, economic, social, and practical knowledge – in order to design and build structures, machines, devices, systems, materials and processes. Some of the major branches of the engineering profession include civil engineering, military engineering, mechanical engineering, chemical engineering, electrical engineering, aerospace engineering, computer engineering, and biomedical engineering.

Inventors

Before engineering was recognized as a formal profession, women with engineering skills often sought recognition as inventors. Tabitha Babbit (1784–1853?) was an American toolmaker who invented the first circular saw. Sarah Guppy (1770–1852) was an Englishwoman who patented a design for bridge foundations. Naval engineer Henrietta Vansittart (1833-1883) held patents across the world for the Lowe Vansittart propeller and was the first female to write, read, and illustrate her own diagrams and drawings for a scientific article presented at Association of Foreman Engineers and Draughtsmen. Mary Dixon Kies (1752–1837) was the first American woman to receive a patent for her method of weaving straw in 1809.

19th century: entry into technical professions

With the coming of the Industrial Revolution in the 19th century, new technology-based occupations opened up for both men and women. Sarah Bagley (1806–?) is remembered not only for her efforts to improved working conditions for women mill workers in Lowell, Massachusetts, in the 1830s and 1840s, but also for being one of the earliest women to work as a telegraph operator. Mathilde Fibiger (1830–1872), a Danish novelist and advocate of women's rights, became a telegraph operator for the Danish State Telegraph system in the 1860s.

Engineering began to be taught as a formal academic discipline in the late 18th and early 19th centuries. The École Polytechnique in France was established in 1794 to teach military and civil engineering; West Point Military Academy in the United States established a program modeled after the École Polytechnique in 1819. Rensselaer Polytechnic Institute (RPI) began to teach civil engineering in 1828. However, none of these institutions admitted women as students at the time of their founding.

In the 19th century, women who performed engineering work often had academic training in mathematics or science. Ada Lovelace (1815–1852), Lord Byron's daughter, was privately schooled in mathematics before beginning the collaboration with Charles Babbage on his analytical engine that would earn her the designation of the "first computer programmer". Hertha Marks Ayrton (1854–1923), a British engineer and inventor who helped develop electric arc lighting, studied mathematics at Cambridge in 1880, but was denied a degree, as women were only granted certificates of completion at the time. Therefore, moving to the University of London, which granted her a bachelor of Science degree in 1881. Similarly, Mary Engle Pennington (1872–1952), an American chemist and refrigeration engineer, completed the requirements for a BS degree in chemistry at the University of Pennsylvania in 1892, but was given a certificate of proficiency instead.

Elizabeth Bragg and Julia Morgan became the first women to receive a bachelor's degree in engineering, by the University of California, Berkeley - U.S.A, in civil engineering (1876) and mechanical engineering (1894). In the same year of Morgan's accomplish, Bertha Lamme was also graduated from Ohio State University in mechanical engineering.

Mary Hegeler Carus was the first woman to graduate in engineering from the University of Michigan in 1882. She went on to study at the Bergakademie Freiberg, the first woman to be legally enrolled. Mary Hegeler studied in Freiberg from April 1885 to Easter 1886, but she had to have a private laboratory because she was a woman. Although her academic performance was excellent, she was not allowed to officially graduate because she was a woman. She went on to run the family business, Matthiessen-Hegeler Zinc Company in La Salle, at one time the largest producer of zinc in the US.

Rita de Morais Sarmento (1872–1931) was the first woman to obtain an Engineering degree in Europe. She enrolled at the Academia Politécnica do Porto to study civil engineering of public works, which she concluded with various distinctions in 1894. Two years later, she was granted with the "Civil Engineering certificate of capability" to practise as a professional engineer, and although she never did, she was the first formally and fully recognised European female engineer. Lydia Weld was the first woman to graduate in engineering from the Massachusetts Institute of Technology, starting her studies in 1898 and going on to work as a draughtsman in the engineering division of Newport News Shipbuilding and Dry Dock Company. She later became the second woman member of the American Society of Mechanical Engineers.

Other women in engineering in the same time period include three Danish women: Agnes Klingberg, Betzy Meyer, and Julie Arenholt, who graduated from 1897 to 1901, at the Polyteknisk Læreanstalt, today known as the Danmarks Tekniske Universitet.

Women without formal engineering degrees were also integral to great 19th century civil engineering feats. Emily Warren Roebling is recognized as managing the construction of the Brooklyn Bridge, and was the first person to cross the bridge at its opening ceremony in 1883. Roebling's husband, Washington Roebling, worked as the chief engineer for the Brooklyn Bridge project until he fell ill of decompression sickness. Upon her husband's illness, Emily Warren Roebling assumed her husband's duties at the project site, and taught herself about material properties, cable construction, calculating catenary curves and other subjects.

20th century: entry into engineering programs

In the early years of the twentieth century, a few women were admitted to engineering programs, but they were generally looked upon as curiosities by their male counterparts.

1900s

On 27 July 1904, Maria Elisabeth Bes graduated in chemical engineering from the Polytechische School te Delft, becoming the first female graduate engineer in the Netherlands. In 1906, Anna Boyksen became the first female engineering student at the Technische Hochschule München in Germany.

Nora Stanton Blatch Barney (1883–1971), daughter of Harriot Stanton Blatch and granddaughter of Elizabeth Cady Stanton, was the first woman to receive a degree in civil engineering from Cornell University in 1905. In the same year, she was accepted as a junior member of the American Society of Civil Engineers; however, twelve years later, after having worked as an engineer, architect, and engineering inspector, her request for an upgrade to associate membership was denied. Olive Dennis (1885–1957), who became the second woman to graduate from Cornell with a civil engineering degree in 1920, was initially hired by the Baltimore and Ohio Railroad as a draftsman; however, she later became the first person to claim the title of Service Engineer when this title was created.

Cleone Benest passed the City and Guilds of London Institute's motor-engineering examination, the Royal Automobile Club's mechanical test in 1908 and took the Portsmouth Municipal College examination for heat engines in 1910. Using the professional name of C. Griff, she joined several engineering organizations and established a consultancy business in Mayfair. Alice Perry was one of the first formally recognised female engineers in Europe, graduated with a degree in engineering in 1908 from Queen's College, Galway. In 1908, Emma Strada was the first woman engineering graduate in Italy, coming third out of 62 in her class.

Elisa Leonida Zamfirescu (1887–1973), due to prejudices against women in the sciences, was rejected by the School of Bridges and Roads in Bucharest, Romania. However, in 1909, she was accepted at the Royal Academy of Technology in Berlin. She graduated from the university in 1912, with a degree in engineering, specialising in chemistry, possibly becoming one of the first women engineers in the world.

1910s

In 1911, the Higher Women's Polytechnical Courses in St. Petersburg, founded in 1906 much through the effort of Praskovia Arian, a Jewish-Russian journalist and feminist, was granted university-level status together with other Russian women's higher educational institutions. By 1916, about 50 female engineers graduated from the institution.

Nina Cameron Graham graduated from University of Liverpool on 6 July 1912 with a degree in Civil Engineering, the first British woman to qualify as an engineer. She married a fellow student and moved to Canada. Maria Artini enrolled in the Polytechnic University of Milan in 1912, graduating in electrical engineering section in 1919 with a grade of 90/100. She was the second female graduate of the Polytechnic and the first female electrical engineering graduate in Italy.

In 1914 Vera Sandberg was the only woman among 500 male students at Chalmers University of Technology, in Gothenburg, graduating in 1917 to become Sweden's first woman engineer. She is now commemorated by a statue, two streets & a hot air balloon.

Edith Clarke, the inventor of the graphical calculator, was the first woman to earn a degree in MIT's electrical engineering department in 1918. Clarke also became the first woman admitted to the American Institute of Electrical Engineers, the precursor to the IEEE. She taught at the University of Texas Austin, where she was the only woman faculty member in the engineering department.

Elisa Bachofen was the first female civil engineer in Argentina, graduating from the University of Buenos Aires in 1918. Her sister Esther Elena Bachofen (1895–1943) followed in her footsteps and became the fourth female civil engineer in Argentina, qualifying in 1922.

In 1919, in the United Kingdom, the first engineering society for women was founded - the Women's Engineering Society or WES as it is commonly known - and it is still active today, continuing to support women in engineering. Founders included Lady Katharine Parsons, who was instrumental in the engineering work of her husband Sir Charles Parsons, their daughter and first President of WES Rachel Parsons, house builder and suffragette, Laura Annie Willson, Eleanor Shelley-Rolls, Margaret Rowbotham, Margaret, Lady Moir, with Caroline Haslett the founding Secretary.

Justicia Acuña was the first woman in Chile to qualify as a civil engineer, graduating from the University of Chile in 1919. She went on to work Department of Roads and Works of the Empresa de los Ferrocarriles del Estado. Since 1991, the Justicia Acuña Mena Award has been awarded every two years to an outstanding woman engineer in the practice of her profession.

Anne-Marcelle Schrameck became the first French woman engineer to graduate from l'École nationale supérieure des mines de Saint-Étienne (the National School of Mines of Saint-Étienne), in 1919. She was the only woman to attend for 50 years as the rules were changed after her entry due to concerns of the suitability of women undertaking mining internships.

Loughborough College (now University) admitted the first cohort of women engineers in 1919, including mechanical engineer Verena Holmes and engineer, writer and traveller Claudia Parsons.

1920s

Juana Pereyra graduated from the Faculty of Engineering of the Universidad de la República in Uruguay, with the title of Ingeniera de Puentes y Caminos (Engineer of Bridges and Roads) in November 1920, making her one of the first female engineers in South America.

Adele Racheli graduated in industrial mechanical engineering from the Polytechnic University of Milan in 1920, the first woman to graduate from the course. In 1925, she opened a patent protection office Racheli & Bossi Patent Office in Milan, in partnership with a colleague Rosita Bossi, who graduated from the Polytechnic University of Milan in Electrotechnics in 1924.

In 1921, Sébastienne Guyot (1894-1941) graduated in mechanics and engineering from the Central School of Paris in the first year group to allow women as students. She became an aeronautical engineer, ending her career as Head of the Helicopter Service at the French Arsenal de l'Aéronautique.

In 1922, Marguerite Massart graduated from the Université Libre de Bruxelles with a degree in civil engineering, making her the first woman to qualify as an engineer in Belgium. She later set up a successful foundry business in Ghent and introduced a desalinisation project and early solar panels in the first hotel on Sal Island in Cape Verde. Hélène Mallebrancke was the first female Belgian civil engineering graduate from University of Ghent, later keeping the Allied telecommunications networks in the Ghent region operational against huge odds during World War Two for which she was decorated posthumously by both the French government and the Belgian authorities.

Kathleen M. Butler was the first member of staff appointed to the Sydney Harbour Bridge team in 1922, acting as the project manager for the large international engineering project in Australia.

On 30 June 1923, Marie Schneiderová-Zubaníková became the first woman in Czechoslovakia to graduate in civil engineering, from the Czech Technical University in Prague. Germaine Benoit graduated in chemical engineering in 1923 from the Institut de chimie appliquée and on 1 June 1924 joined the Pasteur Institute.

In 1925, Annette Ashberry was the first woman to be elected to the UK Society of Engineers and delivered the first address by a woman to the Society's members on 1 November 1926.

In 1927, Elsie Eaves was the first woman admitted to full membership to the American Society of Civil Engineers. Martha Schneider-Bürger became the first German female civil engineer, graduating from Technische Hochschule Munich, a predecessor of Technical University of Munich in 1927. Greta Woxén (née Westberg) became Sweden's first female civil engineer when she graduated from the Kungliga Tekniska högskolan (the Royal Institute of Technology) in 1928.

1930s

The first woman to earn a civil engineering degree in Mexico was Concepción Mendizábal Mendoza in 1930.

Rachel Shalon (Hebrew: רחל שלון) graduated in structural engineerings from the Technion in Haifa in 1930, becoming the first woman engineer in what was then Mandatory Palestine and later Israel. She was made a professor of structural engineering in 1960 and was the first of all Technion graduates, male or female, to reach the rank of full professor.

Ying Hsi Yuan trained as a Civil Engineer in Peiping in the 1930s and worked in bridge design in China before taking a postgraduate engineering degree in University of Liverpool in the 1940s, later working in Hong Kong.

In 1931, Asta Hampe received her diploma in telecommunications engineering from the Technische Hochschule in Berlin, going on to work in a range of engineering work in the next two decades, although she was fired from her job for being a woman when the Nazis came to power in 1933. She later became a professor of economics.

Marie Louise Compernolle was the first female Flemish chemical engineer, graduating in 1932 with a PhD in chemical engineering from Ghent University, the first female PhD in engineering from Ghent.

Hürriyet Sırmaçek graduated from the Istanbul Technical University as Turkey's first bridge engineer in 1935, going on to have a long career as a bridge and structural engineer.

In 1935, Gjuvara Noerieva graduated from the Metallurgical Faculty of the Leningrad Polytechnic Institute, the first Azerbaijani woman to be a professional metallurgist, and the first Azerbaijani woman to work in the metallurgical industry.

Virginia Sink graduated as a chemical engineer from the University of Colorado in 1936, finishing in the top three of her class. She went to work for Chrysler where in 1938 she became the first woman to graduate with a masters in engineering from the Chrysler Institute of Engineering and was the first woman automotive engineer at Chrysler.

Beatriz Ghirelli graduated as a Mechanical and Electrical Engineer in 1938, the first woman to graduate in the subject from National University of La Planta, and the second woman in Argentina to earn the qualification.

In 1939, Isabel Gago graduated from Lisbon's Instituto Superior Técnico, one of the first two women to graduate in the field of chemical engineering in Portugal. She was the second woman to graduate and then work in engineering in Portugal (the first was Maria Amélia Chaves, the first woman to graduate in civil engineering) . Gago was the first woman to teach chemical engineering, spending her career at her alma mater.

World War II engineering programs for women

The entry of the United States into World War II created a serious shortage of engineering talent as men were drafted into the armed forces at the same time that industry ramped up production of armaments, battleships, and airplanes. The U.S. Office of Education initiated a series of courses in science and engineering that were open to women as well as men.

Private programs for women included GE on-the-job engineering training for women with degrees in mathematics and physics, and the Curtiss-Wright Engineering Program had Curtiss-Wright Cadettes (e.g., Rosella Fenton). The company partnered with Cornell, Penn State, Purdue, the University of Minnesota, the University of Texas, RPI, and Iowa State University to create an engineering curriculum that eventually enrolled over 600 women. The course lasted ten months and focused primarily on aircraft design and production.

Thelma Estrin (1924–2014), who would later become a pioneer in the fields of computer science and biomedical engineering, took a 1942 three-month engineering assistant course at Stevens Institute of Technology and earned University of Wisconsin BSc, MSc, and PhD degrees.

Through an accelerated program brought on by the war, Lois Graham (1925-2013) graduated from Rensselaer Polytechnic Institute in 1946 and was the first woman in the United States to receive a Ph.D. in mechanical engineering from Illinois Institute of Technology (M.S. ME ’49, Ph.D. ’59).

Postwar era

In 1943, the United States Army authorized a secret project at the University of Pennsylvania's Moore School of Electrical Engineering to develop an electronic computer to compute artillery firing tables for the Army's Ballistic Research Laboratory. The project, which came to be known as ENIAC, or Electronic Numerical Integrator and Computer, was completed in 1946.

Previous to the development of the ENIAC, the U.S. Army had employed women trained in mathematics to calculate artillery trajectories, at first using mechanical desk calculators and later the differential analyzer developed by Vannevar Bush, at the Moore School. In 1945, one of these "computers", Kathleen McNulty (1921–2006), was selected to be one of the original programmers of the ENIAC, together with Frances Spence (1922–2012), Betty Holberton (1917–2001), Marlyn Wescoff, Ruth Lichterman (1924–1986), and Betty Jean Jennings (1924–2011). McNulty, Holberton, and Jennings would later work on the UNIVAC, the first commercial computer developed by the Remington Rand Corporation in the early 1950s.

Rebeca Uribe Bone became the first woman to graduate in engineering in Colombia in 1945, from the Pontifical-Bolivarian University of Medellin. She went on to work as a chemical engineer in the Bavaria brewing company. In 1948, her sister Guillermina Uribe Bone became the first woman to receive a degree in civil engineering from the Faculty of Mathematics and Engineering of the National University of Colombia in Bogotá.

Nohemy Chaverra was the first Afro-Colombian woman to graduate with a degree in chemical engineering in Colombia. She graduated from the University of Antioquia in 1951. Her son, Andrés Palacio Chaverra, was Vice-Minister of Labour Relations between 2007 and 2008.

In 1946, Hattie Scott Peterson gained a degree in civil engineering, believed to be the first African-American woman to do so. In 1947, UK engineer Mary Thompson Irvine became the first woman to be elected a chartered member of the Institution of Structural Engineers.

In 1950 Marianna Sankiewicz-Budzyńska graduated with a master's degree in electrical engineering, specialising in radio technology from Gdańsk University of Technology and went on to earn a PhD and become an academic, having a strong influence on the development of electrophonics in Poland and Eastern Europe.

In 1952, Polish electrical engineer Maria Wanda Jastrzębska earned a master's degree in electronics and went on to set up early computer labs and influence university teaching.

Ila Ghose (née Majumdar) was West Bengal's first woman engineer, graduating as a mechanical engineer from the Bengali Engineering College in 1951. Sudhira Das qualified as the first women engineer in the Indian state of Odisha in the early 1950s.

In 1957, Araceli Sánchez Urquijo became the first female civil engineer to work in Spain, having been amongst the first 45 hydropower engineers trained at the Moscow Power Engineering Institute.

From 1958, Laurel van der Wal was the project engineer on three MIA (Mouse-in-Able) launches from Cape Canaveral, as head of bioastronautics at Space Technology Laboratories. She was named the Los Angeles Times's "1960 Woman of the Year in Science" for her work, going on to be the first woman appointed to the Los Angeles Board of Airport Commissioners, in 1961, and served as a commissioner until 1967. In 1968, she served as Los Angeles International Airport's planner.

Premala Sivaprakasapillai Sivasegaram studied engineering at Somerville College, Oxford in the 1960s and became the first female engineer of Sri Lanka.

In 1962, Steve Shirley founded software company Freelance Programmers with a capital of £6, (later FI, then Xansa, since acquired by Steria and now part of the Sopra Steria Group). Having experienced sexism in her workplace, "being fondled, being pushed against the wall", she wanted to create job opportunities for women with dependents, and predominantly employed women, with only three male programmers in the first 300 staff, until the Sex Discrimination Act 1975 made that practice illegal. She also adopted the name "Steve" to help her in the male-dominated business world, given that company letters signed using her real name were not responded to. Her team's projects included programming Concorde's black box flight recorder.

The first International Conference of Women Engineers and Scientists was held in New York in 1964, organised by the US Society of Women Engineers and attended by 493 women from 35 countries. The second International Conference of Women Engineers and Scientists followed in 1967 in Cambridge, UK, organised by the Women's Engineering Society with 309 attendees from 35 countries. Conferences have been held every three to four years since.

Resistance to coeducation in engineering schools, 1950s–1970s

The Cold War and the space race between the United States and the Soviet Union created additional demands for trained engineering talent in the 1950s and 1960s. Many engineering schools in the U.S. that had previously admitted only male students began to tentatively adopt coeducation. After 116 years as an all-male institution, RPI began to admit small numbers of female students in the 1940s. Georgia Tech began to admit women engineering students in 1952, but only in programs not available in other state universities. It would be 1968 before women were admitted to all courses offered by Georgia Tech.

The Massachusetts Institute of Technology (MIT) had graduated its first female student, Ellen Swallow Richards (1842–1911) in 1873; she later became an instructor at MIT. However, until the 1960s, MIT enrolled few female engineering students, due in part to a lack of housing for women students. After the completion of the first women's dormitory on campus, McCormick Hall, in 1964, the number of women enrolled increased greatly. Influenced in part by the second wave feminism movement of the late 1960s and 1970s, female faculty members at MIT, including Mildred Dresselhaus and Sheila Widnall, began to actively promote the cause of women's engineering education.

The École Polytechnique in Paris first began to admit women students in 1972.

Margaret Hamilton is also notable for her contributions to computer and aerospace engineering in the 1970s. Hamilton, the director of the Software Engineering Division of the MIT Instrumentation Laboratory at the time, is famous for her work in writing the on-board guidance code for the Apollo 11 mission.

1980s–1990s

As more engineering programs were opened to women, the number of women enrolled in engineering programs increased dramatically. The number of BA/BS degrees in engineering awarded to women in the U.S. increased by 45 percent between 1980 and 1994. However, during the period of 1984–1994, the number of women graduating with a BA/BS degree in computer science decreased by 23 percent (from 37 percent of graduates in 1984 to 28 percent in 1994). This phenomenon became known as "The incredible shrinking pipeline," from the title of a 1997 paper on the subject by Tracy Camp, a professor in the Department of Mathematical and Computer Sciences at the Colorado School of Mines.

Some of the reasons for the decline cited in the paper included:

  • The development of computer games designed and marketed for males only;
  • A perception that computer science was the domain of "hacker/nerd/antisocial" personality types;
  • Gender discrimination in computing;
  • Lack of role models at the university level.

Statistics

United States

According to studies by the National Science Foundation, the percentage of BA/BS degrees in engineering awarded to women in the U.S. increased steadily from 0.4 percent in 1966 to a peak of 20.9 percent in 2002, and then dropped off slightly to 18.5 percent in 2008. However, the trend identified in "The incredible shrinking pipeline" has continued; the percentage of BA/BS degrees in mathematics and computer science awarded to women peaked in 1985 at 39.5 percent, and declined steadily to 25.3 percent in 2008.

The percentage of master's degrees in engineering awarded to women increased steadily from 0.6 percent in 1966 to 22.9 percent in 2008. The percentage of doctoral degrees in engineering awarded to women during the same period increased from 0.3 percent to 21.5 percent.

Australia

Only 9.6% of engineers in Australia are women, and the rate of women in engineering degree courses has remained around 14% since the 1990s.

United Kingdom

The percentage of female and technology engineering graduates rose from 7 percent in 1984 to 14.6 percent in 2018. The proportion of engineers in industry who are women is, on the other hand, still very low at around 11.8% – the lowest percentage in the EU.

Health technology

From Wikipedia, the free encyclopedia

Health technology is defined by the World Health Organization as the "application of organized knowledge and skills in the form of devices, medicines, vaccines, procedures, and systems developed to solve a health problem and improve quality of lives". This includes pharmaceuticals, devices, procedures, and organizational systems used in the healthcare industry, as well as computer-supported information systems. In the United States, these technologies involve standardized physical objects, as well as traditional and designed social means and methods to treat or care for patients.

Development

Pre-digital Era

During a pre-digital era, patients suffered from inefficient and faulty clinical systems, processes, and conditions. Many medical errors happened in the past due to undeveloped health technologies. Some examples of these medical errors included adverse drug events and alarm fatigue. Alarm fatigue is caused when an alarm is repeatedly triggered or activated and one becomes desensitized to them. As the alarms were sometimes triggered by unimportant events in the past, nurses thought the alarm was not significant. Alarm fatigue is dangerous because it could lead to death and dangerous situations. With technological development, an intelligent program of integration and physiologic sense-making was developed and helped reduce the number of false alarms.

Also, with greater investment in health technologies, fewer medical errors happened. Outdated paper records were replaced in many healthcare organizations by electronic health records (EHR). According to studies, this change has brought a lot of changes to healthcare. Drug administration has improved, healthcare providers can now access medical information easier, provide better treatments and faster results, and save more costs.

Improvement

To help promote and expand the adoption of health information technology, Congress passed the HITECH act as part of the American Recovery and Reinvestment Act of 2009. HITECH stands for Health Information Technology for Economic and Clinical Health Act. It gave the department of health and human services the authority to improve healthcare quality and efficiency through the promotion of health IT. The act provided financial incentives or penalties to organizations to motivate healthcare providers to improve healthcare. The purpose of the act was to improve quality, safety, efficiency, and ultimately to reduce health disparities.

One of the main parts of the HITECH act was setting the meaningful use requirement, which required EHRs to allow for the electronic exchange of health information and to submit clinical information. The purpose of HITECH is to ensure the sharing of electronic information with patients and other clinicians are secure. HITECH also aimed to help healthcare providers have more efficient operations and reduce medical errors. The program consisted of three phases. Phase one aimed to improve healthcare quality, safety and efficiency. Phase two expanded on phase one and focused on clinical processes and ensuring the meaningful use of EHRs. Lastly, phase three focused on using Certified Electronic Health Record Technology (CEHRT) to improve health outcomes.

In 2014, the implementation of electronic records in US hospitals rose from a low percentage of 10% to a high percentage of 70%.

At the beginning of 2018, healthcare providers who participated in the Medicare Promoting Interoperability Program needed to report on Quality Payment Program requirements. The program focused more on interoperability and aimed to improve patient access to health information.

Privacy of Health Data

Phones that can track one's whereabouts, steps and more can serve as medical devices, and medical devices have much the same effect as these phones. In the research article, Privacy Attitudes among Early Adopters of Emerging Health Technologies by Cynthia Cheung, Matthew Bietz, Kevin Patrick and Cinnamon Bloss discovered people were willing to share personal data for scientific advancements, although they still expressed uncertainty about who would have access to their data. People are naturally cautious about giving out sensitive personal information. Phones add an extra level of threat according to the research article Security in Cloud-Computing-Based Mobile Health. Mobile devices continue to increase in popularity each year. The addition of mobile devices serving as medical devices increases the chances for an attacker to gain unauthorized information.

In 2015 the Medical Access and CHIP Reauthorization Act (MACRA) was passed which will be put into play in 2018 pushing towards electronic health records. Health Information Technology: Integration, Patient Empowerment, and Security by K. Marvin provided multiple different polls based on people's views on different types of technology entering the medical field most answers were responded with somewhat likely and very few completely disagreed on the technology being used in medicine. Marvin discusses the maintenance required to protect medical data and technology against cyber attacks as well as providing a proper data backup system for the information.

Patient Protection and Affordable Care Act (ACA) also known as Obamacare and health information technology health care is entering the digital era. Although with this development it needs to be protected. Both health information and financial information now made digital within the health industry might become a larger target for cyber-crime. Even with multiple different types of safeguards hackers somehow still find their way in so the security that is in place needs to constantly be updated to prevent these breaches.

Policy

With the increased use of IT systems, privacy violations were increasing rapidly due to the easier access and poor management. As such, the concern of privacy has become an important topic in healthcare. Privacy breaches happen when organizations do not protect the privacy of people's data. There are four types of privacy breaches, which include unintended disclosure by authorized personnel, intended disclosure by authorized personnel, privacy data loss or theft, and virtual hacking. It became more important to protect the privacy and security of patients' data because of the high negative impact on both individuals and organizations. Stolen personal information can be used to open credit cards or other unethical behaviors. Also, individuals have to spend a large amount of money to rectify the issue. The exposure of sensitive health information also can cause negative impacts on individuals' relationships, jobs, or other personal areas. For the organization, the privacy breach can cause loss of trust, customers, legal actions, and monetary fines.

HIPPA
Health Insurance Portability and Accountability Act of 1996

HIPAA stands for the Health Insurance Portability and Accountability Act of 1996. It is a U.S. healthcare legislation to direct how patient data is used and includes two major rules which are privacy and security of data. The privacy rule protects people's rights to privacy and security rule determines how to protect people's privacy.

According to the HIPAA Security Rule, it ensures that protected health information has three characteristics. They are confidentiality, availability, and integrity. Confidentiality indicates keeping the data confidential to prevent data loss or individuals who are unauthorized to access that protected health information. Availability allows people who are authorized to access the systems and networks when and where that information is in fact needed, such as natural disasters. In cases like this, protected health information is mostly backed up on to a separate server or printed out in paper copies, so people can access it. Lastly, Integrity ensures not using inaccurate information and improperly modified data due to a bad design system or process to protect the permanence of the patient data. The consequences of using inaccurate or improperly modified data could become useless or even dangerous.

Health Organizations of HIPAA also created administrative safeguards, physical safeguards, technical safeguards, to help protect the privacy of patients. Administrative safeguards typically include security management process, security personnel, information access management, workforce training and management, and evaluation of security policies and procedures. Security management processes are one of the important administrative safeguards' examples. It is essential to reduce the risks and vulnerabilities of the system. The processes are mostly the standard operating procedures written out as training manuals. The purpose is to educate people on how to handle protected health information in proper behavior.

Physical safeguards include lock and key, card swipe, positioning of screens, confidential envelopes, and shredding of paper copies. Lock and key are common examples of physical safeguards. They can limit physical access to facilities. Lock and key are simple, but they can prevent individuals from stealing medical records. Individuals must have an actual key to access to the lock.

Lastly, technical safeguards include access control, audit controls, integrity controls, and transmission security. The access control mechanism is a common example of technical safeguards. It allows the access of authorized personnel. The technology includes authentication and authorization. Authentication is the proof of identity that handles confidential information like username and password, while authorization is the act of determining whether a particular user is allowed to access certain data and perform activities in a system like add and delete.

Assessment

The concept of health technology assessment (HTA) was first coined in 1967 by the U.S. Congress in response to the increasing need to address the unintended and potential consequences of health technology, along with its prominent role in society. It was further institutionalized with the establishment of the congressional Office of Technology Assessment (OTA) in 1972–1973. HTA is defined as a comprehensive form of policy research that examines short- and long-term consequences of the application of technology, including benefits, costs, and risks. Due to the broad scope of technology assessment, it requires the participation of individuals besides scientists and health care practitioners such as managers and even the consumers.

Several American organizations provide health technology assessments and these include the Centers for Medicare and Medicaid Services (CMS) and the Veterans Administration through its VA Technology Assessment Program (VATAP). The models adopted by these institutions vary, although they focus on whether a medical technology being offered is therapeutically relevant. A study conducted in 2007 noted that the assessments still did not use formal economic analyses.

Aside from its development, however, assessment in the health technology industry has been viewed as sporadic and fragmented Issues such as the determination of products that needed to be developed, cost, and access, among others, also emerged. These - some argue - need to be included in the assessment since health technology is never purely a matter of science but also of beliefs, values, and ideologies. One of the mechanisms being suggested – either as an element of- or an alternative to the current TAs is bioethics, which is also referred to as the "fourth-generation" evaluation framework. There are at least two dimensions to an ethical HTA. The first involves the incorporation of ethics in the methodological standards employed to assess technologies while the second is concerned with the use of ethical framework in research and judgment on the part of the researchers who produce information used in the industry.

Health technology in the future

Health Technology in Future
Fort Belvoir Community Hospital astounds with groundbreaking technology and devotion to patient care

The practice of medicine in the United States is currently in a major transition. This transition is due to many factors, but primarily because of the implementation and integration of health technologies into healthcare. In recent years, the widespread adoption of electronic health records (EHR) has caused a big impact on healthcare. "The Digital Doctor: Hope, Hype, and Harm at the Dawn of Medicine's Computer Age," by Robert Wachter, aims to inform readers about this transition. Dr. Wachter has reviewed and made points about the future of health technologies in the book. He states that there will be fewer hospitals in the future. Due to the advancement of technologies, people will be more likely to go to hospitals for major surgeries or critical illness. In the future, nurse call buttons will not be needed in hospitals. Instead, robots will deliver medication, take care of patients, and administer the system. In the future, the electronic health record will look different. Healthcare providers will be able to enter the notes via speech-to-text transcriptions in real-time.

Dr. Wachter stated that information will be edited collaboratively across the patient-care team to improve the quality. Also, natural language processing will be more developed to help parse out keywords. In the future, patient data will reside in the cloud. Patients will be able to access their data from any device or location. The data is also accessible for authorized providers and individuals. In the future, big data analysis will constantly be improving. Artificial Intelligence and machine learning will be constantly improving and developing as it receives new data. Alerts will also be more intelligent and efficient than the current systems.

Medical technology

Medical technology, or "Medtech", encompasses a wide range of healthcare products and is used to treat diseases and medical conditions affecting humans. Such technologies are intended to improve the quality of healthcare delivered through earlier diagnosis, less invasive treatment options and reduction in hospital stays and rehabilitation times. Recent advances in medical technology have also focused on cost reduction. Medical technology may broadly include medical devices, information technology, biotech, and healthcare services.

The impacts of medical technology involve social and ethical issues. For example, physicians can seek objective information from technology rather than read subjective patient reports.

A major driver of the sector's growth is the consumerization of Medtech. Supported by the widespread availability of smartphones and tablets, providers can reach a large audience at low cost, a trend that stands to be consolidated as wearable technologies spread throughout the market.

In the years 2010–2015, venture funding has grown 200%, allowing US$11.7 billion to flow into health tech businesses from over 30,000 investors in the space.

Types of Technology

Medical technology has evolved into smaller portable devices, for instance, smartphones, touchscreens, tablets, laptops, digital ink, voice and face recognition and more. With this technology, innovations like electronic health records (EHR), health information exchange (HIE), Nationwide Health Information Network (NwHIN), personal health records (PHRs), patient portals, nanomedicine, genome-based personalized medicine, Geographical Positioning System (GPS), radio frequency identification (RFID), telemedicine, clinical decision support (CDS), mobile home health care and cloud computing came to exist.

Medical imaging and Magnetic resonance imaging (MRI) have been long used and proven Medical Technologies for medical research, patient reviewing, and treatment analyzing. With the advancement of imagining technologies, including the use of faster and more data, higher resolution images, and specialist automation software, the capabilities of medical imaging technology are growing and yielding better results. As the imaging hardware and software evolve this means that patients will need to use less contrasting agents, and also spend less time and money.

3D printing is another major development in healthcare. It can be used to produce specialized splints, prostheses, parts for medical devices and inert implants. The end goal of 3D printing is being able to print out customized replaceable body parts. In the following section, it will explain more about 3D printing in healthcare. New types of technologies also include artificial intelligence and robots.

3D printing

3D printing is the use of specialized machines, software programs and materials to automate the process of building certain objects. It is having a rapid growth in the prosthesis, medical implants, novel drug formulations and the bioprinting of human tissues and organs.

Companies such as Surgical Theater, provide new technology that is capable of capturing 3D virtual images of patients' brains to use as practice for operations. 3D printing allows medical companies to produce prototypes to practice before an operation created with artificial tissue.

3D printing technologies are great for bio-medicine because the materials that are used to make allow the fabrication with control over many design features. 3D printing also has the benefits of affordable customization, more efficient designs, and saving more time. 3D printing is precise to design pills to house several drugs due to different release times. The technology allows the pills to transport to the targeted area and degrade safely in the body. As such, pills can be designed more efficiently and conveniently. In the future, doctors might be giving a digital file of printing instructions instead of a prescription.

Besides, 3D printing will be more useful in medical implants. An example includes a surgical team that has designed a tracheal splint made by 3D printing to improve the respiration of a patient. This example shows the potential of 3D printing, which allows physicians to develop new implant and instrument designs easily.

Overall, in the future of medicine, 3D printing will be crucial as it can be used in surgical planning, artificial and prosthetic devices, drugs, and medical implants.

Artificial Intelligence

Artificial Intelligence (AI) is a program that enables computers to sense, reason, act and adapt. AI is not new, but it is growing rapidly and tremendously. AI can now deal with large data sets, solve problems, and provide more efficient operation. AI will be more potential in healthcare because it provides easier accessibility of information, improves healthcare, and reduce cost. There are different factors that drive AI in healthcare, but the two most important are economics and the advent of big data analytics. Costs, new payment options, and people's desire to improve health outcomes are the primary economic drivers of the AI. Based on the reading, AI can save $150 million annually in the US by 2026. Also, AI growth is expected to reach $6.6 million by 2021. Big data analytics is another big driver because we are in the age of big data. The data is extremely helpful to assist the integration of AI in healthcare because it ensures the execution of complex tasks, quality, and efficiency.

Applications of Artificial Intelligence

AI brings many benefits to the healthcare industry. AI helps to detect diseases, administer chronic conditions, deliver health services, and discover the drug. Also, AI has the potential to address important health challenges. In healthcare organizations, AI is able to plan and relocate resources. AI is able to match patients with healthcare providers that meet their needs. AI also helps improve the healthcare experience by using an app to identify patients' anxieties. In medical research, AI helps to analyze and evaluate the patterns and complex data. For instance, AI is important in drug discovery because it can search relevant studies and analyze different kinds of data. In clinical care, AI helps to detect diseases, analyze clinical data, publications, and guidelines. As such, AI aids to find the best treatments for the patients. Other uses of AI in clinical care include medical imaging, echocardiography, screening, and surgery.

Education

Medical virtual reality provides doctors multiple surgical scenarios that could happen and allows them to practice and prepare themselves for these situations. It also permits medical students a hands-on experience of different procedures without the consequences of making potential mistakes. ORamaVR is one of the leading companies that employ such medical virtual reality technologies to transform medical education (knowledge) and training (skills) to improve patient outcomes, reduce surgical errors and training time and democratize medical education and training.

Robots

Modern robotics have made huge progress and contribution to healthcare. Robots can help doctors in performing variety tasks. Robotics adoption is increasing tremendously in hospitals . The following are different ways to improve healthcare by using robots:

Robotic Spinal Surgery
Robotic Spinal Surgery

Surgical robots are one of the robotic systems, which allows a surgeon to bend and rotate tissues in a more flexible and efficient way. The system is equipped with a 3D magnification vision system that can translate the hand movements of the surgeon to be precise in-order to perform a surgery with minimal incisions. Other robotics systems include the ability to diagnose and treat cancers. Many scientists began working on creating a next-generation robot system to assist the surgeon in performing knee and other bone replacement surgeries.

Assistant robots will also be important to help reduce the workload for regular medical staff. They can help nurses with simple and time-consuming tasks like carrying multiple racks of medicines, lab specimen or other sensitive materials.

Shortly, robotic pills are expected to reduce the number of surgeries. They can be moved inside a patient and delivered to the desired area. In addition, they can conduct biopsies, film the area and clear clogged arteries.

Overall, medical robots are extremely useful in assisting physicians; however, it might take time to be professionally trained working with medical robots and for the robots to respond to a clinician's instructions. As such, many researchers and startups were working constantly to provide solutions to these challenges.

Assistive Technologies

Assistive technologies are products designed to provide accessibility to individuals who have physical or cognitive problems or disabilities. They aim to improve the quality of life with assistive technologies. The range of assistive technologies is broad, ranging from low-tech solutions to physical hardware, to technical devices. There are four areas of assistive technologies, which include visual impairment, hearing impairment, physical limitations, cognitive limitations. There are many benefits of assistive technologies. They enable individuals to care for themselves, work, study, access information easily, improve independence and communication, and lastly participate fully in community life.

Consumer-driven healthcare software

As part of an ongoing trend towards consumer-driven healthcare, websites or apps which provide more information on health care quality and price to help patients choose their providers have grown. As of 2017, the sites with the most number of reviews in descending order included Healthgrades, Vitals.com, and RateMDs.com. Yelp, Google, and Facebook also host reviews with a large amount of traffic, although as of 2017 they had fewer medical reviews per doctor. Disputes around online reviews can lead to websites by health professionals alleging defamation.

Patient safety organizations and government programs which have historically assessed quality have made their data more accessible over the internet; notable examples include the HospitalCompare by CMS and the LeapFrog Group's hospitalsafetygrade.org.

Patient-oriented software may also help in other ways, including general education and appointments.

Disclosure of legal disputes including medical license complaints or malpractice lawsuits has also been made easier. Every state discloses license status and at least some disciplinary action to the public, but as of 2018, this was not accessible via the internet for a few states. Consumers can look up medical licenses in a national database, DocInfo.org, maintained by the medical licensing organizations which contains limited details. Other tools include DocFinder at docfinder.docboard.org and certificationmatters.org from the American Board of Medical Specialties. In some cases more information is available from a mailed or walk-in request than the internet; for example, the Medical Board of California removes dismissed accusations from website profiles, but these are still available from a written or walk-in request, or a lookup in a separate database. The trend to disclosure is controversial and generate significant public debate, particularly about opening up the National Practitioner Data Bank. In 1996, Massachusetts became the first state to require detailed disclosure of malpractice claims.

Self-Monitoring

Smartphones, tablets, and wearable computers have allowed people to monitor their health. These devices run numerous applications that are designed to provide simple health services and the monitoring of one's health with finding as critical problems to health as possible . An example of this is Fitbit, a fitness tracker that is worn on the user's wrist. This wearable technology allows people to track their steps, heart rate, floors climbed, miles walked, active minutes, and even sleep patterns. The data collected and analyzed allow users not just to keep track of their health but also help manage it, particularly through its capability to identify health risk factors.

There is also the case of the Internet, which serves as a repository of information and expert content that can be used to "self-diagnose" instead of going to their doctor. For instance, one need only enumerate symptoms as search parameters at Google and the search engine could identify the illness from the list of contents uploaded to the World Wide Web, particularly those provided by expert/medical sources. These advances may eventually have some effect on doctor visits from patients and change the role of the health professionals from "gatekeeper to secondary care to facilitator of information interpretation and decision-making." Apart from basic services provided by Google in Search, there are also companies such as WebMD that already offer dedicated symptom-checking apps.

Technology testing

All medical equipment introduced commercially must meet both United States and international regulations. The devices are tested on their material, effects on the human body, all components including devices that have other devices included with them, and the mechanical aspects.

The Medical Device User Fee and Modernization Act of 2002 was created to speed up the FDA's approval process of medical technology by introducing sponsor user fees for a faster review time with predetermined performance targets for review time. In addition, 36 devices and apps were approved by the FDA in 2016.

Careers

There are numerous careers to choose from in health technology in the USA. Listed below are some job titles and average salaries.

  • Athletic Trainer,Mean Salary: $41,340. Athletic trainers treat athletes and other individuals who have sustained injuries. They also teach people how to prevent injuries. They perform their job under the supervision of physicians.
  • Dental Hygienist, Mean Salary: $67,340. Dental hygienists provide preventive dental care and teach patients how to maintain good oral health. They usually work under dentists' supervision.
