The World Health Organisation estimates that there are 9.2 million doctors, 19.4 million nurses and midwives, 1.9 million dentists and other dental personnel, 2.6 million pharmacists and other pharmacy personnel, and more than 1.3 million community health workers worldwide, making the healthcare industry one of the largest. There is no universally agreed sector classification, but the key sectors of the healthcare industry can be broadly classified 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". Each segment of the healthcare industry provides a different mix of health-related jobs, wages and salaries. The healthcare industry includes establishments ranging from small-town private doctors' practices employing only a medical assistant to busy inner-city hospitals providing thousands of diverse jobs.
Healthcare data management will primarily revolve around intelligent systems that can provide permission control, anonymity and confidentiality when dealing with healthcare data. Healthcare companies operate hospitals, clinics, laboratories, psychiatric centres and nursing homes. Although hospitals constitute only 1 per cent of all health care establishments, they employ 35 per cent of all workers. Americans spend more on healthcare, not because they use more medical devices, but because of the high cost of medical treatment.
Medicare, dental insurance, corporate wellness services, Medicaid, pharmacy benefit management, health care consultants, etc. The health sector benefits from a strong medical research and development system, in cooperation with the higher education system and the technology industry. This would be an alternative to working within a healthcare facility and instead working with outpatients in their homes. Many of the healthcare jobs that are regulated by a state licence require healthcare professionals to complete continuing education at regular intervals in order to maintain a valid licence.
Depending on the size and nature of your particular section of the healthcare sector, the number of workers and the departments you supervise will differ. About 76% of health care establishments are practices of doctors, dentists or other health professionals. The diversity and breadth of the health sector depends mainly on the size of a country's population. A digitised healthcare system will enable better diagnostics, improve the quality of care and reduce operating costs.
Investors in the healthcare sector face considerable political risk as a result of the uncertainty surrounding the tug-of-war between politics and industry interests.
