The Health is defined in terms of general state of mind and body. It is not identified in terms of medical condition or sickness. It is the complete state in terms of physical, psychological and social well being.

The health indicators are the attributes or features which characterize either the individuals or population. These are generally very useful in describing public health problems and in assessing the level of fitness of a particular population. The socio-economic factors can also be assessed in relation to this. The programs like quality of life etc. Can be assessed using these indicators.

The job of the medical doctor is to restore human well being by treating the disease of the patient. In general terms, the medical doctor or the physician diagnosis the disease or injury, and then gives medication for the relief and maintenance of human fitness. The medical doctor communicates with the patient, and the patient trusts the doctor. The patient assumes that the doctor has enough knowledge for treatment in terms of drugs and medications.

Although the physician job is the most important job for patient treatment, it goes without saying that the health department needs numerous other services to run the hospitals, clinics etc. The careers are plenty. Some of these careers are nurses, ambulance paramedic, community worker, aged care worker, clinical record coder, disability support workers, community workers, child care workers, cardiac technicians, technicians, hospital ward clerks, massage therapist, medical physicist, pharmacy assistant, psychologists etc.

The nurses provide care to the patients selflessly. They give their services to nursing homes, homes and extended care facilities in the healthy care environment and community environment. This profession is very well respected, because of the highest qualities of tolerance and patience in them. The nurses carry a lot of responsibility on their shoulders for caring the patients.

The aged care workers provide care and companionship to the ageing people. Ageing people are restricted to their homes, most of the time. Therefore, this care is extended to them at home. These workers help them in their household chores. In addition, they give them emotional support.

Ambulance paramedic specialize in pre-hospital care of the patients. They care for the sick and injured. They can efficiently handle stress. They provide emergency transport to take them to hospital or medical facilities.

The general contribution of General Practitioners (GPs) in the care of patient is being recognised widely. There are many freelance GPs who prefer to work independently as self-employed. They are the GP Locums, who provide services wherever, there is shortage of staff. These Locum GPs also work for after-hours services. These are the services, which look after the patient care, when most of the private clinics are closed e. G. On the weekends. These locum doctors are very flexible, as they have to adapt to the new environment as and when they are employed. They are exposed to a wide range of work environments.

The health system works efficiently, with the help of physicians and surgeons, who are supported by a range of services provided by the allied staff.
