Ethical Review Standards for Human Subject Research in US, 1945-1972

SUMMARY

Between the end of World War II in 1945 and 1972, the ethical landscape for human subject research in the United States was largely self-regulated by the medical profession, with evolving governmental oversight. The Nuremberg Code, established in 1947, provided foundational international ethical principles following wartime atrocities [2]. In the U.S., the Department of Health, Education, and Welfare (DHEW) began adopting policies on human subjects research as early as 1953, particularly for the National Institutes of Health's Clinical Center [3]. The World Medical Association's Declaration of Helsinki in 1964 further provided international recommendations for biomedical research involving human subjects [6].

However, a lack of consistent and mandatory federal regulations allowed for significant ethical lapses, as exemplified by the Tuskegee Syphilis Study, which continued until its public exposure in 1972 [slug: tuskegee-syphilis-study-1932-1972]. This period precedes the formal establishment of comprehensive federal ethical guidelines and Institutional Review Boards (IRBs) across US institutions, which were largely mandated by the National Research Act of 1974 and the subsequent Belmont Report [1, 8]. Prior to these legislative actions, the implementation and enforcement of ethical standards varied significantly among institutions.

STRONGEST CASE FOR

Proponents of the view that ethical standards existed argue that the medical profession had its own codes and that international declarations like the Nuremberg Code (1947) and the Declaration of Helsinki (1964) provided guiding principles for ethical research. Institutions like NIH also adopted internal policies from the early 1950s. While not universally enforced by federal law, these standards represented a recognized ethical framework within the research community that some institutions and researchers adhered to.

STRONGEST CASE AGAINST

Critics contend that despite some existing guidelines, the period from 1945 to 1972 was largely characterized by insufficient and inconsistently applied ethical oversight. The absence of mandatory, formalized federal regulations and independent review bodies like IRBs meant that researchers often operated with considerable autonomy, leading to significant ethical abuses such as the Tuskegee Syphilis Study. The very creation of the National Research Act of 1974 and the Belmont Report indicates a prior systemic failure in protecting human subjects.

OPEN QUESTIONS — PENDING LEADS

What specific, institution-level ethical review policies were in place at major US medical universities (e.g., Harvard, Johns Hopkins, UPenn) between 1945 and 1972?
Were there any federal government audits or internal reports from DHEW or NIH prior to 1974 that assessed the adherence of institutions to existing ethical guidelines for human subject research?
What role did professional medical associations (e.g., AMA, APA) play in enforcing or advocating for ethical standards in human research during this period, beyond issuing general declarations?
How widely was the Nuremberg Code explicitly adopted or referenced in the protocols or ethical statements of US research institutions between 1947 and 1972?
What documented instances of internal institutional ethical review or rejection of research proposals involving human subjects exist from major US institutions between 1945 and 1972?
