Health systems can support a person's health requirements through primary health care, including illness prevention, treatment, palliative care, and more. This approach also guarantees that the delivery of healthcare is centred on patients' needs and respects their preferences. The most inclusive, fair, and economical way to achieve universal health coverage is widely regarded as primary healthcare. The ability of health systems to anticipate, react to, and recover from shocks and crises must also be strengthened. The enhancement of one's health through the prevention, diagnosis, treatment, amelioration, or cure of disease, illness, injury, and other physical and mental impairments in humans is known as health care or healthcare. Health professionals and other allied health areas provide healthcare. Health care encompasses all fields related to medicine, including dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, and athletic training. It encompasses work done in the fields of public health, primary care, secondary care, and tertiary care. Organizations designed to address the health requirements of certain populations are known as health systems. The World Health Organization (WHO) states that in order for a health care system to operate effectively, it needs a funding mechanism, a workforce that is properly trained and compensated, reliable data on which to base decisions and policies, and well-maintained medical facilities that can provide high-quality drugs and technologies. There are many major health and safety risks that healthcare personnel must deal with. Blood borne pathogens and biological hazards are among them, as are possible chemical and drug exposures, waste anaesthetic gas exposures, respiratory dangers, ergonomic dangers from lifting and repetitive motion, dangers from lasers, dangers from workplace violence, dangers from labs, and dangers from radioactive material and x-rays. Formaldehyde, which is used to preserve pathology specimens, ethylene oxide, glutaraldehyde, and paracetic acid, which are used to sterilise objects, among many other chemicals used in medical labs, are some of the potential chemical exposures. Compared to other industries, the healthcare and social support sector has the most workplace injuries. This sector has one of the highest rates of occupational diseases and injuries, and those rates are still rising. The healthcare and social support sector reported a 40% increase in injury and illness cases in 2020, which remained greater than any other sector of the private economy (806,200 cases) (2020 Survey of Occupational Injuries and Illnesses, BLS). A minimum of one day off work was required in more than half of these cases (447,890). In 2020, there were 5.5 cases overall per 100 FTE workers in this industry, up from 3.8 cases per 100 FTE workers in 2019. With 15,360 cases, nursing aides had one of the highest rates of musculoskeletal diseases of any occupation in 2020. For nursing assistants, instances involving days away from work accounted for 52% of all cases. The primary goal of health care is to improve health in order to improve quality of life. To maintain their valuation and continue to operate, commercial enterprises concentrate on generating financial profit. For health care to live up to its promise to society, it must prioritise generating social profit. Patient safety is a discipline that focuses on safety in health care by preventing, reducing, reporting, and analysing errors and other types of unnecessary harm that frequently result in adverse patient events. Until the 1990s, when multiple countries reported significant numbers of patients harmed and killed by medical errors, the frequency and magnitude of avoidable adverse events, also known as patient safety incidents, experienced by patients were not well known. Recognizing that healthcare errors affect one out of every ten patients worldwide, the World Health Organization (WHO) refers to patient safety as an endemic concern.  Indeed, patient safety has emerged as a distinct healthcare discipline, backed by a nascent but developing scientific framework. There is a substantial body of theoretical and research literature that informs patient safety science.
