About Health Services

Health services include the diagnosis, treatment and amelioration of illness, injury and other physical and mental impairments. They involve a wide range of disciplines including biostatistics, clinical sciences, epidemiology, decision theory, finance, law and political science.

Many healthcare professionals hone their skills by earning online or in-person continuing education units. These can count toward certificate or licensure renewal requirements.

Preventive care

Preventive care is medical services that protect against health emergencies, illnesses or diseases before they manifest. These services include annual checkups, immunizations and screening tests.

Depending on your age and medical history, your doctor will recommend the preventive healthcare you need. Generally, most private health insurance plans and those obtained through the health marketplace must cover these services without any cost to you.

However, it’s important to note that preventive and routine Care is not the same as diagnostic or treatment services. Your health insurance provider will provide you with information on preventive services, and online tools to help you stay on track with your appointments (preventive or routine). You may also want to contact your physician directly.


In medicine, diagnosis is central to medical practice and health policy. Vaccination schedules, antibiotic prescription policies and research priorities depend on the accuracy of diagnoses. A diagnosis also legitimises a patient’s illness and confers access to support services and benefits.

Diagnosis is an iterative process that involves a physician’s response to information garnered from patients and their families, examination of the body, and medical tests. In this process, the physician attempts to reason backward from symptoms and risk factors to a probable cause. This iterative process leads to one or more working diagnoses that may be revised with further information, as well as by the patient’s prognosis.


Rehabilitation is an essential health service that can prevent, reduce and manage disability. It complements and maximizes the impact of medical and surgical interventions.

It includes education and practice to help people regain their abilities, such as regaining hand-grip strength after an injury or learning how to live with pain. It can also include equipment like wheelchairs and physiotherapy sessions, and it is usually provided by specialists.

Rehabilitation hospitals are places where a person receives specialized inpatient rehabilitation care, including 24-hour rehab nursing and daily physician management. Patients here typically have complex therapy needs. They are often referred from other healthcare facilities or directly from home.

Long-term care

Long-term care (LTC) provides help on a continuous basis for people whose abilities are impaired by illness or disability. It can include services such as bathing, dressing, grooming, using the toilet and eating. It can also include support and assistance with mobility and transferring.

It may be provided by family members, home health aides or other medical professionals. It can be delivered at home, in community settings like adult day care and assisted living, or in nursing homes. It can be paid for privately or through government programs such as Medicaid. Some people purchase private long-term care insurance to assist with the costs.

Community health

Community health focuses on addressing the root causes of a community’s poor health and well-being. This type of care addresses the holistic needs of patients, including medical, dental and pharmacy services, as well as housing, transportation and education.

Community health can be provided at the local level, in a specific geographic area such as a neighborhood or city. It differs from public health in its scope, which includes a larger population, such as an entire state or region. The defining factors of community health are related to living conditions, such as access to healthy food options in areas known as “food deserts” or safe outdoor spaces for physical activity.
