Objective: To determine if journals' instructions for authors require that manuscripts being considered for publication indicate that studies involving human subjects had appropriate institutional review board (IRB) approval.
Design: A descriptive study of the ethical guidelines published in the Instructions for Authors sections of the 102 English-language biomedical research journals listed in the 1995 Abridged Index Medicus.
Intervention: Literature review.
Main outcome measure: Policy regarding IRB approval of studies that involve human subjects.
Results: Of the 102 journals surveyed, 48 (47%) require IRB approval of studies involving human subjects as a prerequisite for publication, and 25 (24%) do not present or refer the author to any information related to human research ethics. Of the remaining journals, 15 (15%) referred authors to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, 3 (3%) to the Declaration of Helsinki, and 10 (10%) simply indicated that informed consent should be obtained. There was only 1 medical specialty (anesthesiology) in which all the representative journals presented the same ethical requirement. In the 48 journals that clearly required IRB approval of studies, 37 (77%) documented IRB approval with a statement in the manuscript, 7 (15%) required a separate signed statement from the author, and 4 (8%) did not mention a method of documentation.
Conclusions: The results of this study suggest that about half of the 102 English-language biomedical research journals listed in the 1995 Abridged Index Medicus do not publish guidelines indicating that IRB approval of studies involving human research subjects is a requirement for publication. The manner in which publication requirements related to ethical standards are presented in biomedical research journals is extremely variable.
