PEER-REVIEW IS AN EFFECTIVE SCREENING PROCESS TO EVALUATE MEDICAL MANUSCRIPTS

Objective.-To measure the effectiveness of peer review as a screening process to evaluate medical manuscripts. Design.-Retrospective. Settin g.-The editorial office of the American Journal of Surgery (AJS). Meth od.-A MEDLINE search was conducted of publications from 1984 to 1992 f or manuscripts that were identical or similar to those rejected by AJS between January and December 1989. Manuscripts that were submitted to AJS by foreign authors were excluded because of the presumed difficul ty in tracking foreign-language publications. Main Outcome Measures.-T he percentage of manuscripts rejected by AJS that were subsequently pu blished in journals indexed by MEDLINE, the time from rejection to ult imate publication, and the journal of publication. The reasons for rej ection were also documented. We assumed that the majority of rejected manuscripts would be published within 3 years after rejection. Results .-One hundred twenty-five manuscripts submitted by North American auth ors were rejected by AJS in 1989, and 62% were not subsequently publis hed in another core medical journal during the study period. The avera ge duration between rejection and later publication was 17 months. Of those manuscripts subsequently published, 54% appeared in general surg ical journals, including 12% that were revised, reevaluated, and later accepted by AJS. Twenty-nine percent of the rejected manuscripts were published in specialty medical journals, 10% in state and local journ als, and the remainder in general medical journals. Twenty-eight perce nt of the authors of rejected manuscripts had previously and subsequen tly published manuscripts on very similar subjects. Conclusions.-Our d ata indicate that the review process serves as a sieve and influences whether manuscripts are published in core medical journals. This was d emonstrated by the fact that rejected manuscripts often were not publi shed in other indexed medical journals.
