A health professional may operate within all branches of health care, including medicine, surgery, dentistry, midwifery, pharmacy, psychology, nursing or allied health professions. A health professional may also be a public/community health expert working for the common good of the society.
Practitioners and professionals
The healthcare workforce
comprises a wide variety of professions and occupations who provide
some type of healthcare service, including such direct care
practitioners as physicians, nurses, surgeons, dentists, physical and behavior therapists, as well as allied health professionals such as phlebotomists, medical laboratory scientists, dieticians, and social workers.
They often work in hospitals, healthcare centres and other service
delivery points, but also in academic training, research, and
administration. Some provide care and treatment services for patients in
private homes. Many countries have a large number of community health workers who work outside formal healthcare institutions. Managers of healthcare services, health information technicians, and other assistive personnel and support workers are also considered a vital part of health care teams.
Healthcare practitioners are commonly grouped into health professions.
Within each field of expertise, practitioners are often classified
according to skill level and skill specialization. “Health
professionals” are highly skilled workers, in professions that usually
require extensive knowledge including university-level study leading to
the award of a first degree or higher qualification.
This category includes physicians, physician assistants, dentists,
midwives, radiographers, registered nurses, pharmacists,
physiotherapists, optometrists, operating department practitioners and
others. Allied health professionals, also referred to as "health
associate professionals" in the International Standard Classification of Occupations,
support implementation of health care, treatment and referral plans
usually established by medical, nursing, and other health professionals,
and usually require formal qualifications to practice their profession.
In addition, unlicensed assistive personnel assist with providing health care services as permitted.
Another way to categorize healthcare practitioners is according
to the sub-field in which they practice, such as mental health care,
pregnancy and childbirth care, surgical care, rehabilitation care, or
public health.
Mental health practitioners
A mental health practitioner is a health worker who offers services for the purpose of improving the mental health of individuals or treating mental illness. These include psychiatrists, clinical psychologists, clinical social workers, psychiatric-mental health nurse practitioners, marriage and family therapists, mental health counselors,
as well as other health professionals and allied health professions.
These health care providers often deal with the same illnesses,
disorders, conditions, and issues; however their scope of practice often differs. The most significant difference across categories of mental health practitioners is education and training.
Maternal and newborn health practitioners
A maternal and newborn health practitioner is a health worker who
deals with the care of women and their children before, during and after
pregnancy and childbirth. Such health practitioners include obstetricians, midwives, obstetrical nurses
and many others. One of the main differences between these professions
is in the training and authority to provide surgical services and other
life-saving interventions. In some developing countries, traditional birth attendants,
or traditional midwives, are the primary source of pregnancy and
childbirth care for many women and families, although they are not
certified or licensed.
Geriatric care practitioners
A geriatric care practitioner plans and coordinates the care of the
elderly and/or disabled to promote their health, improve their quality
of life, and maintain their independence for as long as possible. They
include geriatricians, adult-gerontology nurse practitioners, clinical nurse specialists, geriatric clinical pharmacists, geriatric nurses, geriatric care managers, geriatric aides, Nursing aides, Caregivers and others who focus on the health and psychological care needs of older adults.
Surgical practitioners
A surgical practitioner
is a healthcare professional who specializes in the planning and
delivery of a patient's perioperative care, including during the
anaesthetic, surgical and recovery stages. They may include general and
specialist surgeons, surgeon's assistant, assistant surgeon, surgical assistant, anesthesiologists, anesthesiologist assistant, nurse anesthetists, surgical nurses, clinical officers, operating department practitioners, anaesthetic technicians, perioperative nursing, surgical technologists, and others.
Rehabilitation care practitioners
A
rehabilitation care practitioner is a health worker who provides care
and treatment which aims to enhance and restore functional ability and
quality of life to those with physical impairments or disabilities. These include physiatrists, rehabilitation nurses, clinical nurse specialists, nurse practitioners, physiotherapists, orthotists, prosthetists, occupational therapists, recreational therapists, audiologists, speech and language pathologists, respiratory therapists, rehabilitation counsellors, physical rehabilitation therapists, athletic trainers, physiotherapy technicians, orthotic technicians, prosthetic technicians, personal care assistants, and others.
Eye care practitioners
Care and treatment for the eye and the adnexa may be delivered by ophthalmologists specializing in surgical/medical care, or optometrists specializing in refractive management and medical/therapeutic care.
Medical diagnosis providers
Medical diagnosis providers are health workers responsible for the
process of determining which disease or condition explains a person's
symptoms and signs. It is most often referred to as diagnosis with the
medical context being implicit. This usually involves a team of
healthcare providers in various diagnostic units. These include radiographers, radiologists, medical laboratory scientists, pathologists, and related professionals.
Oral care practitioners
A dental care practitioner is a health worker who provides care and treatment to promote and restore oral health. These include dentists and dental surgeons, dental assistants, dental auxiliaries, dental hygienists, dental nurses, dental technicians, dental therapists or oral health therapists, and related professionals.
Foot care practitioners
Care and treatment for the foot, ankle, and lower leg may be delivered by podiatrists, chiropodists, pedorthists, foot health practitioners, podiatric medical assistants, podiatric nurse and others.
Public health practitioners
A public health practitioner
focuses on improving health among individuals, families and communities
through the prevention and treatment of diseases and injuries,
surveillance of cases, and promotion of healthy behaviors. This category
includes community and preventive medicine specialists, public health nurses, clinical nurse specialists, dietitians, environmental health officers, paramedics, epidemiologists, health inspectors, and others.
Alternative medicine practitioners
In many societies, practitioners of alternative medicine
have contact with a significant number of people, either as integrated
within or remaining outside the formal health care system. These include
practitioners in acupuncture, Ayurveda, herbalism, homeopathy, naturopathy, Reiki, Shamballa Reiki energy healing, Siddha medicine, traditional Chinese medicine, traditional Korean medicine, Unani, and Yoga. In some countries such as Canada, chiropractors and osteopaths (not to be confused with doctors of osteopathic medicine in the United States) are considered alternative medicine practitioners.
Practice conditions and regulations
Shortages of health professionals
Many jurisdictions report shortfalls in the number of trained health human resources
to meet population health needs and/or service delivery targets,
especially in medically underserved areas. For example, in the United
States, the 2010 federal budget
invested $330 million to increase the number of doctors, nurses, and
dentists practicing in areas of the country experiencing shortages of
trained health professionals. The Budget expands loan
repayment programs for physicians, nurses, and dentists who agree to
practice in medically underserved areas. This funding will enhance the
capacity of nursing schools to increase the number of nurses. It will also allow states to increase access to oral health care through dental workforce development grants. The Budget’s new resources will sustain the expansion of the health care workforce funded in the Recovery Act. There were 15.7 million health care professionals in the US as of 2011.
In Canada, the 2011 federal budget announced a Canada Student Loan
forgiveness program to encourage and support new family physicians,
nurse practitioners and nurses to practice in underserved rural or
remote communities of the country, including communities that provide
health services to First Nations and Inuit populations.
In Uganda, the Ministry of Health
reports that as many as 50% of staffing positions for health workers in
rural and underserved areas remain vacant. As of early 2011, the
Ministry was conducting research and costing analyses to determine the
most appropriate attraction and retention packages for medical officers,
nursing officers, pharmacists, and laboratory technicians in the
country’s rural areas.
At the international level, the World Health Organization
estimates a shortage of almost 4.3 million doctors, midwives, nurses,
and support workers worldwide to meet target coverage levels of
essential primary health care interventions. The shortage is reported most severe in 57 of the poorest countries, especially in sub-Saharan Africa.
Occupational hazards
The healthcare workforce face unique health and safety challenges and is recognized by the National Institute for Occupational Safety and Health (NIOSH) as a priority industry sector in the National Occupational Research Agenda (NORA) to identify and provide intervention strategies regarding occupational health and safety issues.
Occupational stress and occupational burnout are highly prevalent among health professionals. Some studies suggest that workplace stress is pervasive in the health care industry because of inadequate staffing levels, long work hours, exposure to infectious diseases and hazardous substances leading to illness or death, and in some countries threat of malpractice
litigation. Other stressors include the emotional labor of caring for
ill people and high patient loads. The consequences of this stress can
include substance abuse, suicide, major depressive disorder, and anxiety,
all of which occur at higher rates in health professionals than the
general working population. Elevated levels of stress are also linked to
high rates of burnout, absenteeism and diagnostic errors, and to reduced rates of patient satisfaction. In Canada, a national report (Canada's Health Care Providers)
also indicated higher rates of absenteeism due to illness or disability
among health care workers compared to the rest of the working
population, although those working in health care reported similar
levels of good health and fewer reports of being injured at work. There is some evidence that cognitive-behavioral therapy, relaxation training and therapy (including meditation and massage),
and modifying schedules can reduce stress and burnout among multiple
sectors of health care providers. Research is ongoing in this area,
especially with regards to physicians, whose occupational stress and
burnout is less researched compared to other health professions.
Exposure to respiratory infectious diseases like tuberculosis (caused by Mycobacterium tuberculosis) and influenza can be reduced with the use of respirators; this exposure is a significant occupational hazard for health care professionals. Exposure to dangerous chemicals, including chemotherapy drugs, is another potential occupational risk. These drugs can cause cancer and other health conditions. Healthcare workers are also at risk for diseases that are contracted through extended contact with a patient, including scabies. Health professionals are also at risk for contracting blood-borne diseases like hepatitis B, hepatitis C, and HIV/AIDS through needlestick injuries or through contact with bodily fluids. This risk can be mitigated with vaccination when there is a vaccine available, like with hepatitis B. In epidemic situations, such as the 2014-2016 West African Ebola virus epidemic or the 2003 SARS outbreak,
healthcare workers are at even greater risk, and were
disproportionately affected in both the Ebola and SARS outbreaks. In
general, appropriate personal protective equipment
(PPE) is the first-line mode of protection for healthcare workers from
infectious diseases. For it to be effective against highly contagious
diseases, personal protective equipment must be watertight and prevent
the skin and mucous membranes from contacting infectious material.
Different levels of personal protective equipment created to unique
standards are used in situations where the risk of infection is
different. Practices such as triple gloving and multiple respirators do
not provide a higher level of protection and present a burden to the
worker, who is additionally at increased risk of exposure when removing
the PPE. Compliance with appropriate personal protective equipment rules
may be difficult in certain situations, such as tropical environment or
low-resource settings. A 2016 Cochrane systematic review found low
quality evidence that using more breathable fabric in PPE, double
gloving, and active training reduce the risk of contamination.
Female health care workers may face specific types of workplace-related health conditions and stress. According to the World Health Organization, women predominate in the formal health workforce in many countries, and are prone to musculoskeletal injury
(caused by physically demanding job tasks such as lifting and moving
patients) and burnout. Female health workers are exposed to hazardous
drugs and chemicals in the workplace which may cause adverse
reproductive outcomes such as spontaneous abortion and congenital malformations. In some contexts, female health workers are also subject to gender-based violence including from coworkers and patients.
Healthcare workers are at higher risk of on-the-job injury due to
violence. Drunk, confused, and hostile patients and visitors are a
continual threat to providers attempting to treat patients. Frequently,
assault and violence in a healthcare setting goes unreported and is
wrongly assumed to be part of the job.
Violent incidents typically occur during one-on-one care; being alone
with patients increases healthcare workers' risk of assault. In the United States, healthcare workers suffer ⅔ of nonfatal workplace violence incidents.
Psychiatric units represent the highest proportion of violent
incidents, at 40%; they are followed by geriatric units (20%) and the
emergency department (10%). Workplace violence can also cause
psychological trauma.
Slips, trips, and falls are the second-most common cause of
worker's compensation claims in the US, and cause 21% of work absences
due to injury. These injuries most commonly result in strains and sprains; women, those older than 45, and those who have been working less than a year in a healthcare setting are at the highest risk.
Health care professionals are also likely to experience sleep deprivation due to their jobs. Many health care professionals are on a shift work schedule, and therefore experience misalignment of their work schedule and their circadian rhythm.
In 2007, 32% of healthcare workers were found to get fewer than 6 hours
of sleep a night. Sleep deprivation also predisposes healthcare
professionals to make mistakes that may potentially endanger a patient.
An epidemiological study published in 2018 examined the hearing
status of noise-exposed health care and social assistance (HSA) workers
sector to estimate and compare the prevalence of hearing loss
by subsector within the sector. Most of the HSA subsector prevalence
estimates ranged from 14% to 18%, but the Medical and Diagnostic
Laboratories subsector had 31% prevalence and the Offices of All Other
Miscellaneous Health Practitioners had a 24% prevalence. The Child Day
Care Services subsector also had a 52% higher risk than the reference
industry.
Regulation and registration of professionals
Practicing without a license
that is valid and current is typically illegal. In most jurisdictions,
the provision of health care services is regulated by the government.
Individuals found to be providing medical, nursing or other professional
services without the appropriate certification or license may face
sanctions and criminal charges leading to a prison term. The number of
professions subject to regulation, requisites for individuals to receive professional licensure, and nature of sanctions that can be imposed for failure to comply vary across jurisdictions.
In the United States, under Michigan
state laws, an individual is guilty of felony if identified as
practicing in the health profession without a valid personal license or
registration. Health professionals can also be imprisoned if found
guilty of practicing beyond the limits allowed by their licences and
registration. The state laws define the scope of practice for medicine, nursing, and a number of allied health professions. In Florida, practicing medicine without the appropriate license is a crime classified as a third degree felony,
which may give imprisonment up to five years. Practicing a health care
profession without a license which results in serious bodily injury
classifies as a second degree felony, providing up to 15 years' imprisonment.
In the United Kingdom, healthcare professionals are regulated by the state; the UK Health and Care Professions Council
(HCPC) protects the 'title' of each profession it regulates. For
example, it is illegal for someone to call himself an Occupational
Therapist or Radiographer if they are not on the register held by the
HCPC.
