what are the different sanitation industries?

For the healthcare sector to function, it is necessary to have a wide variety of people with different levels of training. Hospitals and health systems continually change their service offerings and respond to a variety of internal and external forces, such as reimbursement issues, technological advances and changes in the populations they serve. There is no universally accepted classification of sectors, but the key sectors of the healthcare industry can be broadly categorised into four sectors called "Healthcare services and facilities", "Medical device manufacturers, hospital equipment and supplies", "Health insurance, medical services and managed care" and "Pharmaceuticals and related segments". Healthcare systems dictate the means by which individuals and institutions pay for and receive healthcare services.

These changes will continue to reshape not only the nature of the healthcare workforce, but also the way healthcare is delivered. Professional and administrative support occupations account for a much smaller percentage of employment in this segment compared to other parts of the healthcare industry. Medical doctors, chiropractors, dermatologists, nutritionists and dieticians, psychologists, social workers, marriage counsellors, optometrists, physiotherapists and other alternative healthcare providers fall into this category. Some health workers need a bachelor's degree, such as social workers, health service managers and some nurses.

Technological innovation, integration of medicine and healthcare, intelligent health data management and patient-centred restructuring are the key issues. The provision of health services from primary care to secondary and tertiary levels of care is the most visible part of any health system, both to users and to the general public. Growth in the sector will also come as a result of the shift from hospital care to less costly outpatient and home care, due to improvements in diagnostic tests and surgical procedures, together with patients' desire to be treated at home. Over the first twenty-five years of this transformation, the government contribution to healthcare expenditure has declined from 36% to 15%, and the burden of managing this decline has largely fallen on patients.

Other approaches to defining the scope of the health industry tend to adopt a broader definition, including also other key health-related actions such as education and training of health professionals, regulation and management of health service delivery, provision of traditional and complementary medicines, and administration of health insurance. Traditional inpatient positions are no longer the only option for many future health workers; those seeking a career in this field must be prepared to work in a variety of work settings. Home care workers and other health care workers who travel as part of their work are exposed to the possibility of injury in road traffic accidents. The health sector is made up of companies that provide clinical services, manufacture medicines and medical equipment, and provide health-related support services such as health insurance.
