Lack of shared decision making in cancer screening discussions: results from a national survey.

Abstract

Clinicians are encouraged to support patients in achieving shared decision making (SDM) for cancer screening. To describe decision making processes and outcomes for cancer screening discussions. A 2011 national Internet survey of adults aged ≥50 years who made cancer screening decisions (breast, BrCa; colorectal, CRC; prostate, PCa) within the previous 2 years was conducted. Participants were asked about their perceived cancer risk; how informed they felt about cancer tests; whether their healthcare provider addressed pros/cons of testing, presented the option of no testing, and elicited their input; whether they were tested; and their confidence in the screening decision. Data were analyzed in 2013-2014 with descriptive statistics and logistic regression. Overall, 1,134 participants (477 men, 657 women) aged ≥50 years made cancer screening decisions, and 1,098 (354, BrCa; 598, CRC; 146, PCa) decisions were discussed with a healthcare provider. Most discussions (51%-67%) addressed pros of screening some or a lot, but few (7%-14%) similarly addressed cons. For all cancer screening decisions, providers usually (63%-71%) explained that testing was optional, but less often asked women (43%-57%) than men (70%-71%) whether they wanted testing. Only 27%-38% of participants reported SDM, 69%-93% underwent screening, and 55%-76% would definitely make the same decision again. Perceived high/average cancer risk and feeling highly informed were associated with confidence in the screening decision. Discussions often failed to provide balanced information and meet SDM criteria. Supporting SDM could potentially improve the quality of cancer screening decisions.
