The Concept of Indication in Medical Decision-Making: A Critical Analysis of Its Ethical and Normative Dimensions

Indications play a crucial role in medical decision-making processes and provide legal and ethical legitimacy for medical interventions. While medical indication constitutes the most important component of this term, it is also possible to refer to psychological, social, religious, and legal types of indication. This article aims to explore the ethical and legal dimensions of the concept of indication and to provide a normative analysis of medical indication. After exploring the indication from legal and ethical perspectives, we first examine the relationship between medical indication and the concept of disease. The concept is further evaluated in relation to the principle of autonomy. Medical indication provides a framework for medical intervention and, in a sense, makes a recommendation. In principle, patients may reject or consent to this recommendation; however, they cannot request any medical procedure without a medical indication. The discussion section elaborates on these points by examining the case of cesarean section on maternal request, and makes the results more concrete. In conclusion, indication is an indispensable normative concept underpinning the legal and ethical legitimacy of medical interventions. Procedures carried out solely at the request of patients such as cesarean sections without medical necessity pose health risks and violate the principle of justice due to resource misuse. Moreover, it is ethically unacceptable for physicians to base decisions on patient demands in the absence of medical indication-whether defensively or due to economic incentives. Accordingly, there is a need for legal reforms that support physicians in decision-making and for clinical guidelines that clarify ambiguities in determining indications.
