Long-acting reversible contraception methods are effective tools in family planning. However, resident physicians and other health care trainees may experience knowledge gaps and low utilization because of limited opportunity for training. The purpose of this pilot study is to evaluate self-assessed knowledge, counseling, and long-acting reversible contraception (LARC) device placement skills among health care trainees who attended a 1-day simulation-based training. In addition, we describe a simulation-based training program we developed to facilitate the use of LARC among health professionals. We conducted a cross-sectional evaluation of health care trainees attending simulation-based training on 2 occasions in 2017 and one occasion in 2018 in Chicago, Illinois. Participants rated their experience, comfort providing counseling, and placement skills with all LARC methods. Knowledge was measured using a series of multiple-choice questions. Responses to the survey were summarized using frequencies and percentages. A total of 253 health care professionals attended the simulations, and 244 completed the presurvey (96.4% response rate). Of those, 172 respondents were health care trainees, of which a majority were resident physicians. More than half reported never using top-tier methods in practice. Most indicated moderate to low knowledge to counsel patients and low skills to place each of the devices before training; self-reported knowledge and skills increased after completing training. Presimulation knowledge scores ranged from 0 to 19, with a median score of 14 of 19 correct responses. After training, average scores increased by 3 points (P < 0.0001). One-day training events can provide didactic education and simulation-based skills training in device placement that may result in increased access among the patients served by these providers.
