ObjectiveTo assess the impact of a Shared Decision-Making (SDM) tool for fertility awareness-based methods (FABMs) of family planning.MethodsClinicians familiar with at least one FABM were randomly invited to participate in a prospective cross-over study to compare usual practice to the use of the SDM tool when discussing FABMs with patients. Patients completed surveys pre- and post-office visit and six months later. The primary outcome explored the effect of online education on use of the SDM tool on clinicians' knowledge of FABMs.ResultsOf 278 clinicians contacted, 54% could not be reached, and 15% did not provide women's health services. The 26 clinicians enrolled were experienced, with more than half recommending FABMs for ≥10 years, and 73% recommending more than one FABM to patients. Knowledge scores significantly improved after online training and use of the SDM tool (baseline mean score = 9.54 (scale of 0–12); post-training mean score = 10.73,p< 0.002).ConclusionsEducation about FABMs and training on use of the SDM tool improved knowledge scores even among an experienced cohort of clinicians.InnovationThe novel SDM tool can better equip clinicians to meet the rising patient interest in FABMs.
