Four Components Of Health:

There are four components of health: physical, psychological, social and motor. These interrelated aspects of well-being are interdependent and cannot be adequately measured on a single dimension. Hence, health assessment is done according to each of these aspects, in order to provide the needed comprehensive management services for individuals, groups as well as communities. Health is essential for all of us and thus, there is an increasing demand for health care services. The increasing need for health services is reflected in the rapidly increasing number of health practitioners and professionals required by the health care system.

The health care system caters to the general population through health professionals such as doctors, nurses, physician assistants, psychologists and other medical staff. There are two types of health professionals namely primary care practitioners and specialists. The primary care practitioners, who are often referred to as family physicians, perform preventive health care, primary medical examinations, prescribe drugs , and conduct laboratory tests and offer consultations on a confidential basis; while the specialists, who are referred to as the interventional radiologists, specialists in interventional radiology, surgical radiologists, and pathologists, perform advanced diagnostic procedures, treatments and surgery, and provide diagnostic services on a confidential basis.

Some health services are covered by insurance plans, while others are provided through fee-for-service basis. Some health professionals work at the patients’ homes, so they have contact only with the patients. Thus, there is a significant gap between the roles of health care professionals such as physicians, surgeons, and radiologists, as well as other health care services technicians, and patient care providers such as nurses, nurse practitioners, and pharmacy technicians. Health care delivery requires training, supervision, and certification by a practicing physician or surgeon. In some instances, health professionals are trained in a shorter period of time to become a licensed practical nurse (LPN) or a pharmacy technician, but they must maintain a degree from an approved program.

The primary care practitioner is responsible for prevention services, which include overall health management, including diagnosis, consultation, and treatment of health problems. The primary care practitioner facilitates communication between patients and health care providers. For example, he/she would facilitate the patient’s review of the medical history and choose the recommended health care provider. In addition, he/she would also screen patients for diseases and conditions that might be life threatening or that require immediate medical attention. In addition, primary care professionals offer preventative services such as vaccination and screening for cholesterol, blood pressure, obesity, and diabetes.

Another category of allied health professionals are direct patient care specialists. These health professionals provide medical care to patients who require in-person assistance, telephone access, or home health services. They are usually physicians, chiropractors, and nurses. These professionals coordinate the primary care physicians, refer patients to other appropriate health professionals, perform basic lab tests, and administer medications.
