The role of diagnosis in medical practice and society

Abstract

Organization of knowledge is needed to help doctors learn and recall information in their clinical practice. Diagnostic constructs help, providing prototypes against which doctors can diagnose patient conditions. They then seek to confirm or disprove this diagnosis by searching for relevant information. Attached to these diagnostic constructs are information such as causes, prognosis, and treatment. Diagnostic constructs are provisional and should be changed if information suggests they are incorrect. They also aid communication between professionals for teaching and research, and have important social functions such as providing access to healthcare, determining eligibility for welfare, offering administrative and payment functions, and collecting health statistics. Some social effects of diagnostic constructs can be harmful, such as stigma. Diagnostic constructs are included in broad diagnostic formulations including relevant clinical information.
