Background: The U.S. Preventive Services Task Force recommends providers engage women aged 40-49 years in shared decision-making (SDM) for mammography. This requires mammography knowledge, adequate time to discuss screening, and self-confidence in doing so. Yet, to date, no studies have assessed provider readiness to engage younger women in SDM.
Methods: An online survey of primary care providers was conducted in Cleveland in 2015. It inquired about knowledge of screening benefits and harms, including the impact of screening on mortality, risk of additional imaging, biopsy, overtreatment following screening, and likelihood of a true-positive result. Key knowledge was defined as accurate estimation of the impact of screening on mortality and risk of overtreatment. Respondents reported time typically spent with patients discussing mammography, self-assessed competence in engaging patients in screening discussions, and perspectives on SDM for mammography.
Results: Of 612 providers invited, 220 completed the survey (response rate: 36%). Knowledge of harms was low: 90% and 82% underestimated the risk of additional imaging or breast biopsy, respectively. Sixty-two percent correctly estimated screening's impact on mortality. The majority (83%) believed in SDM for mammography, yet, most (77%) spent less than 5 minutes with patients discussing screening. Of those who believed in SDM, only 10% had key mammography knowledge and also felt highly competent at engaging women in screening discussions.
Conclusions: Most providers in our sample were inadequately equipped to engage women in SDM for mammography. Broad-based efforts are needed to increase the capacity of providers to engage younger women in decision-making.
