What is Medicine?

Medicine is fundamentally a moral enterprise devoted to the welfare of persons through the systematic practice of defining, preventing, and treating disease using patient history, physical examination, and clinical parameters to guide effective treatments and reduce suffering, morbidity, and mortality. 1

Core Definition and Purpose

Medicine operates through several interconnected dimensions:

The Clinical Foundation

The practice of medicine is based on:

  • Defining disease through patient history and physical examination
  • Using clinical laboratory parameters to enable selection and guidance of effective treatments
  • Reducing or eliminating symptoms, morbidity, mortality, and burden of disease 2

The implicit definition centers on clinical utility—the ability of an intervention to reduce or eliminate adverse health outcomes 3.

The Moral Imperative

Medicine is fundamentally a moral enterprise because it is devoted to the welfare of the persons it treats 1. This moral foundation requires:

  • Fulfilling commitment to patient welfare, which may include refusing requests for nonbeneficial care
  • Addressing not just physical disease but also sources of pain and suffering that are not physical in nature
  • Helping patients maintain hope and find meaning even when cure is impossible 1

Evolution Toward Patient-Centered Care

Medicine is increasingly moving away from sole clinician-determined evaluation of physical health outcomes toward acknowledgment of the patient's self-reported experience 3. This shift recognizes:

  • Patient-reported outcomes including pain, fatigue, self-efficacy, and social participation
  • Personal utility alongside clinical utility
  • Outcomes of immediate importance to patients: symptom frequency/severity, life planning usefulness, and alleviation of psychological burden 3

The Epistemological Framework

What distinguishes medicine as a domain is its demand for empirical evidence to support claims of utility 3. For at least 30 years, evidence-based medicine (EBM) has provided the framework for how medicine defines claims of utility and generates evidence for evaluation 3.

Practical Application

Medicine encompasses both pharmacological and non-pharmacological management 4. Non-pharmacological approaches include patient education, self-management, exercise, behavioral interventions, psychological counseling, and various supportive therapies—all aimed at complementing pharmaceutical treatment when needed.

The Holistic Scope

Medicine addresses multiple dimensions:

  • Prevention of disease and assessment of disease susceptibility
  • Selection of therapy for the individual
  • Monitoring of treatment response 2
  • Palliative care that includes the patient's family and addresses non-medical aspects of illness, focusing on relief of symptoms throughout the disease spectrum 1

Critical Distinction

Medicine must be distinguished from social welfare—while society often attempts to medicalize social problems, it is crucial to separate the main goals of medicine (representing its core values) from secondary goals related to social or individual welfare, poverty, or other societal issues 5.
