Healthcare systems refer to the organized delivery of medical care to individuals and communities by healthcare professionals, institutions, and technologies. This includes the prevention, diagnosis, treatment, and management of various illnesses and health conditions. Healthcare systems typically involve a network of hospitals, clinics, physicians, nurses, pharmacists, and other healthcare providers working together to deliver quality care to patients. The goals of a healthcare system are to improve the health outcomes of individuals, ensure access to healthcare services, control healthcare costs, and promote overall population health. Healthcare systems vary significantly from country to country, with differences in funding sources, delivery models, and healthcare policies. Common challenges in healthcare systems include rising healthcare costs, disparities in access to care, and the need to adapt to new technologies and healthcare innovations.
