The Scope and Sciences of Medicine
Medicine (or medical science) is the scientific study of human health and disease. It involves the diagnosis, prognosis, prevention, treatment and palliation of illness and injury. The scope and sciences of modern medical practice are broad and varied. Physicians are trained in the basic sciences of medicine before entering clinical practice. Those who specialize in different branches of medicine often work together when caring for a patient, with each branch contributing to the overall care plan for that patient.
Some of the broad scientific disciplines that are involved in medicine include physiology, anatomy, biology, chemistry and biomechanics. Biochemistry is the study of the chemistry taking place within living organisms, and it is essential to the fields of medical research, epidemiology and evidence-based medicine.
Molecular biology is the study of the molecular underpinnings of life processes, including DNA replication, transcription and translation. Genetics is the study of inheritance, and it is a central part of modern scientific medical knowledge. Microbiology is the study of microorganisms such as bacteria, fungi and viruses, and it is also important to medicine.
In the laboratory, biochemistry and molecular biology are used in medical research to produce new drugs or therapies. In addition, pharmacology is the study of the action of medicines and their side effects. Medicines are a vital part of modern society, and biomedical engineers are working to develop safer and more effective medications.
The scope and practices of medicine vary widely across countries, with some having universal healthcare systems, while others are privatized or have only limited coverage. In universal healthcare systems, costs are generally lower and pricing more transparent than in private markets. The Vox website illustrates the wide variation in medical billing across the US, with many patients paying extravagant prices for medical services.
Medicine is a complex field, and physicians are required to balance the benefits of each therapy against its risks. Depending on the context, this may involve a discussion with the patient about their willingness to accept risk in the hope of achieving better health outcomes. This is sometimes known as the “benefit-risk” decision.
Contemporary medicine is generally conducted within healthcare systems, which encompass the legal, credentialing and financing frameworks that establish the way in which medical care is provided. The characteristics of a healthcare system are influenced by the health policy of a country, and they may also be influenced by social factors, such as culture and religion, or economic factors. It is generally understood that a healthy population is a fundamental prerequisite for successful medicine. For this reason, efforts are being made to reduce the incidence of chronic diseases and improve preventive care. This is especially true in developing countries, where the burden of disease is greatest. For example, the WHO has set a target of reducing under-5 mortality by 50% by 2025. This will require a comprehensive approach, involving education, lifestyle changes and access to health care. It will also require a multidisciplinary effort, with the support of other sectors, such as the pharmaceutical industry.
