Background: Medication use among pregnant women is widespread, despite limited evidence about the teratogenicity of most medications. Improved physician-patient communication about pregnancy-related medication safety has been identified as a strategy to address this critical issue; however, little is known about physicians' knowledge, attitudes, and practices that could inform tools for information access and sharing to support such communication. The primary objective of this study is to address gaps in what is known about obstetrician-gynecologist views, practices, and needs related to accessing and sharing pregnancy-related medication safety information with patients. Materials and Methods: The basis for this study is a nationally representative, randomized survey of 506 practicing obstetrician-gynecologists. The survey was completed by mail or online between October 26, 2015 and May 8, 2016 with a 52% response rate. Data were weighted to population parameters to reduce the risk of potential nonresponse biases. Analyses included univariate distributions and comparisons between physicians in different residency cohorts using all-pairs dependent t-tests. Results: Findings point to critical features of obstetrician-gynecologist access and sharing of medication safety information. Obstetrician-gynecologists often retrieve medication safety information during a clinical visit. There is widespread provision of potentially problematic "safe lists" to patients, particularly by younger cohorts, and limited counseling for reproductive-aged patients not actively planning a pregnancy. Conclusions: To improve clinical care, physician-patient communication may be enhanced with technical and policy solutions, including improved digital information tools for retrieving and discussing information in the clinical setting; evidence-based, written information for physicians to share with patients; and encouragement for counseling all women of reproductive age receiving teratogenic medications.
