The current study used a retrospective study design. The OMM practice logs for the Advanced OPP curricular semesters 5, 6, and 7, completed by third-year and fourth-year osteopathic medical students from the ATSU-KCOM classes of 2017 and 2018, were reviewed. Logs were in either .pdf or .jpg format and had been submitted to the online educational software platform Blackboard. De-identified data from the logs were manually entered into an Excel (Microsoft) spreadsheet and included the Advanced OPP semester number (5, 6, or 7), date of treatment, type of patient (clinical vs volunteer), sex and age of patient, patient's chief complaint (≤3 categorized by organ system or body region), body regions treated with OMM (1-10), osteopathic manipulative treatment (OMT) techniques used, core clerkship site, and degree of the supervisor (DO or MD). The current study assessed practice patterns of students at 33 core clerkship sites in 9 states: Arizona, Illinois, Kansas, Michigan, Missouri, New Jersey, Ohio, Pennsylvania, and Utah. When the degree of the supervisor was not recorded by the student, we searched for the supervisor's name in the clerkship geographic region to obtain the data. When the search could not identify the supervisor's degree, the degree was recorded as unknown. Practice logs submitted by means other than Blackboard, such as through email, were excluded from the study. The current study was reviewed by the A.T. Still University-Kirksville institutional review board and found to be exempt.
