Health services in the context of "Cure"

Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of health takes into account physical, psychological, and social well-being, among other factors.

Public health is an interdisciplinary field. For example, epidemiology, biostatistics, social sciences and management of health services are all relevant. Other important sub-fields include environmental health, community health, behavioral health, health economics, public policy, mental health, health education, health politics, occupational safety, disability, oral health, gender issues in health, and sexual and reproductive health. Public health, together with primary care, secondary care, and tertiary care, is part of a country's overall healthcare system. Public health is implemented through the surveillance of cases and health indicators, and through the promotion of healthy behaviors. Common public health initiatives include promotion of hand-washing and breastfeeding, delivery of vaccinations, promoting ventilation and improved air quality both indoors and outdoors, suicide prevention, smoking cessation, obesity education, increasing healthcare accessibility and distribution of condoms to control the spread of sexually transmitted diseases.

Community health refers to non-treatment based health services that are delivered outside hospitals and clinics. Community health is a subset of public health that is taught to and practiced by clinicians as part of their normal duties. Community health volunteers and community health workers work with primary care providers to facilitate entry into, exit from and utilization of the formal health system by community members as well as providing supplementary services such as support groups or wellness events that are not offered by medical institutions.

Community health is a major field of study within the medical and clinical sciences which focuses on the maintenance, protection, and improvement of the health status of population groups and communities, in particular those who are a part of disadvantaged communities. It is a distinct field of study that may be taught within a separate school of public health or preventive healthcare. The World Health Organization defines community health as:

Service economy can refer to one or both of two recent economic developments:

• The increased importance of the service sector in industrialized economies. The current list of Fortune 500 companies contains more service companies and fewer manufacturers than in previous decades.
• The relative importance of service in a product offering. The service economy in developing countries is mostly concentrated in financial services, hospitality, retail, health, human services, information technology and education. Products today have a higher service component than in previous decades. In the management literature this is referred to as the servitization of products or a product-service system. Virtually every product today has a service component to it.

The old dichotomy between product and service has been replaced by a Service (economics) service–product continuum [1]. Many products are being transformed into services.

The National Health Service (NHS) is the collective term for the four separate publicly funded healthcare systems of the United Kingdom: the National Health Service (England), NHS Scotland, NHS Wales, and Health and Social Care (Northern Ireland) which was created separately and is often referred to locally as "the NHS". The original systems were established in 1948 (NHS Wales/GIG Cymru was founded in 1969) as part of major social reforms following the Second World War, and officially launched at Park Hospital in Davyhulme, near Manchester, England (now known as Trafford General Hospital). The founding principles were that services should be comprehensive, universal and free at the point of delivery. Each system provides a comprehensive range of health services, provided without charge for residents of the United Kingdom apart from dental treatment and optical care, though NHS patients in England who are not exempt have to pay prescription charges.

Taken together, the four systems in 2015–16 employed around 1.6 million people with a combined budget of £136.7 billion. In 2024, the total health sector workforce across the United Kingdom was 1,499,368.

mHealth (also written as m-health or mhealth), an abbreviation for mobile health, is the practice of medicine and public health supported by mobile devices. The term is most commonly used in reference to using mobile communication devices, such as mobile phones, tablet computers and personal digital assistants (PDAs), and wearable devices such as smart watches, for health services, information, and data collection. The mHealth field has emerged as a sub-segment of eHealth and digital health, the use of information and communication technology (ICT), such as computers, mobile phones, communications satellite, patient monitors, etc., for health services and information. mHealth applications include the use of mobile devices in collecting community and clinical health data, delivery/sharing of healthcare information for practitioners, researchers and patients, real-time monitoring of patient vital signs, the direct provision of care (via mobile telemedicine) as well as training and collaboration of health workers.

In 2019, the global market for mHealth apps was estimated at US$17.92 billion, with a compound annual growth rate of 45% predicted from 2020 to 2027. While mHealth has application for industrialized nations, the field has emerged in recent years as largely an application for developing countries, stemming from the rapid rise of mobile phone penetration in low-income nations. The field, then, largely emerges as a means of providing greater access to larger segments of a population in developing countries, as well as improving the capacity of health systems in such countries to provide quality healthcare.Within the mHealth space, projects operate with a variety of objectives, including increased access to healthcare and health-related information (particularly for hard-to-reach populations); improved ability to diagnose and track diseases; timelier, more actionable public health information; and expanded access to ongoing medical education and training for health workers.
