During 2006, a paper survey was mailed to all 129 allopathic medical schools in the United States and Puerto Rico using a list obtained from the Association of American Medical Colleges. Contents of the survey items were based on existing literature and expert opinion and addressed various topics related to VMS programs, including organizational aspects, program objectives, and practical issues. Responses to the survey items were yes-or-no, multiple-choice, fill-in-the-blank, and free-text responses. Data related to the survey responses were summarized using descriptive statistics.
