The report's lasting achievement was rhetorical and institutional as well as
curricular. It named deficiencies plainly, offered funders and regulators a
shared hierarchy of schools, and made expensive university medicine appear the
legitimate destination of reform. Surviving institutions generally acquired
stronger admissions, longer courses, improved laboratories, and closer clinical
affiliations (Barzansky).
“Flexnerian” later became shorthand for a two-stage scientific and clinical
curriculum. The label can illuminate a dominant model, but it also hides the
work of earlier schools, laboratory investigators, hospital staff, professional
associations, licensing boards, students, patients, and philanthropies. It can
likewise obscure the unequal distribution of reform's costs.
The most defensible conclusion is neither that Flexner invented modern medicine
nor that the report was merely incidental. Bulletin Number Four concentrated
reforms already underway, attached public authority to them, and helped actors
with regulatory and financial power decide which institutions would build the
new system—and which communities would lose one.
