BackgroundSugammadex, aprepitant, and fosaprepitant are increasingly used perioperatively. These medications may interfere with the effectiveness of hormonal contraception. This study assessed anesthesia providers' use of sugammadex and aprepitant, their knowledge of interactions with hormonal birth control, and patient counseling practices to identify possible knowledge gaps or opportunities for practice improvement.MethodsIn January 2023, an electronic survey was distributed to all anesthesia providers at Mayo Clinic sites (Mayo Clinic Rochester, Mayo Clinic Arizona, Mayo Clinic Florida, and Mayo Clinic Health System hospitals). The survey included 32 questions assessing providers' use of sugammadex and aprepitant, their knowledge of the medications' interactions with hormonal contraceptives (HC), their perceptions regarding education of these interactions during training, and their perioperative patient counseling practices. The collected data were analyzed using descriptive statistics.ResultsA total of 337 of 1092 (31%) providers completed the survey. While almost all respondents (324; 96%) knew that sugammadex may interfere with oral contraceptive effectiveness, only 158 (47%) knew about aprepitant's potential contraceptive interference. Only 176 providers (52%) knew the recommended duration for alternative contraceptive methods after use after sugammadex, and 119 providers (35%) knew the recommended duration after aprepitant exposure. Most respondents considered the interference of these perioperative drugs with HCs to be clinically relevant (sugammadex, 217, 64%; aprepitant, 191, 58%). Despite the common belief that the decision between these medications and alternatives should be shared between provider and patient, most providers reported rarely engaging in such shared decision-making (SDM) in practice. Most providers recognized the need for preoperative discussions on sugammadex (280, 83%) and aprepitant (257, 76%), yet 184 providers (73%) never or rarely discussed contraception use before surgery for aprepitant, and 135 (36%) never or rarely did so for sugammadex. Lastly, many providers believed that the interference between sugammadex, aprepitant, and HC was poorly taught during training.ConclusionsThe results of this study highlight the need for increased education and awareness among anesthesia providers regarding drug interactions with HCs during the perioperative period. To facilitate SDM, it is imperative that providers discuss alternative medications and the potential need for additional contraception methods after drug administration and communicate the risks with patients preoperatively to enable informed and SDM. The patient's preferences should be accounted for, especially if they are unwilling or unable to use an alternative contraceptive for 7 to 30 days, thereby avoiding the complexities and burdens of altering birth control methods.Copyright © 2024 International Anesthesia Research Society.
