Abstract

Modern medicine remains marked by a persistent tension between general scientific knowledge and the singularity of individual patients. Alvan Feinstein's attempt to construct a "science of clinical judgment" offers an important examined response to this problem.
This article examines how Feinstein sought to integrate patient singularity into a rigorous epistemological framework and assesses whether his work should be understood merely as a precursor to Evidence-Based Medicine or as an alternative scientific pathway for clinical practice.
A narrative review was conducted using a pearl-growing strategy, beginning with Feinstein's primary works and expanding through their conceptual and bibliographic connections. This approach was complemented by targeted searches in PubMed and Scopus and by a historical-philosophical analysis informed by debates in the philosophy and history of medicine.
Feinstein transformed clinical judgment from a tacit, individual faculty into a structured, collective, and regulable practice. His project relied on the standardization of observation, refinement of clinical classifications, collective validation, and development of clinically meaningful measurements. Clinimetrics extended this project by making subjective, contextual, functional, and patient-centered phenomena scientifically intelligible without reducing them to biomedical mechanisms or psychometric abstractions. These findings indicate that Feinstein did not simply anticipate Evidence-Based Medicine; he developed a distinct epistemological approach centered on the systematic study of singular clinical realities.
Feinstein's work remains relevant because it shows that scientific rigor and attention to patient singularity need not be mutually exclusive. His project provides a critical framework for reconsidering the limits of Evidence-Based Medicine, personalized medicine, and contemporary approaches to clinical measurement.
