Evaluation of the Change in Family Medicine Residents' Confidence and Knowledge in Performing Basic Obstetric Ultrasound Post-training: A Prospective Study.

Introduction The maternity care curriculum guidelines of the American Academy of Family Physicians (AAFP) state that family medicine residents (FMRs) should demonstrate the ability to independently perform limited obstetric ultrasound (OBUS) examinations as a core skill. This study's purpose is to examine whether basic OBUS training enhances the knowledge and confidence of FMRs in performing OBUS. Methods This is a Sparrow Institutional Review Board (IRB)-exempt prospective study that was completed at the Sparrow/Michigan State University (MSU) Family Medicine Residency Program (FMRP) in Michigan between December 2020 and December 2021, involving 40 residents. Assessment of knowledge and confidence in performing OBUS was completed prior to and following the training sessions. For training, an online lecture and two separate hands-on sessions with a pregnant patient were completed. Training materials by Prof. Dr. Mark Deutchman and the University of Washington (UoW) were used. Paired T-test was used for statistical analysis, and a p-value of <0.05 was used to determine statistical significance. Results Thirty-two pre- and 25 post-training questionnaires were collected from the target group. Of the respondents, 92% (n=23) indicated that training increased their confidence levels in performing OBUS. The percentage of reported confidence level of 1 or 2 in performing OBUS (on a Likert scale of 5, with 5 as the highest confidence level) decreased by 60% post-training (p<0.001). Levels 3, 4, and 5 in confidence level were increased. According to the respondents, an increased confidence level in OBUS is helpful for improving trust and rapport between the provider and the patient (92%, n=23), boosting the provider's diagnostic abilities (80%, n=20), improving patient satisfaction (76%, n=19), and decreasing healthcare costs (44%, n=11). Conclusion The basic OBUS training sessions improved the knowledge and confidence of residents in interpreting and performing OBUS; therefore, more OBUS training is needed during the residency.
