Decision aids are important tools in ensuring patients understand the medical choices they face. Our decision aid "Is a PSA Test Right for You?", takes a look at the same medical evidence that the U.S. Preventive Services Task Force (USPSTF) recently reviewed, and highlights what the evidence tells us about the PSA test's benefits- which are uncertain or limited for many men- and the harms of treatment if a screening results in a prostate cancer diagnosis.
The updated Cochrane Collaborative review of 86 randomized control trials (in six countries), involving 34 decisions, set out to find out how well decision aids prepare people to participate in decisions that involve weighing benefits, harms and scientific uncertainty. What the authors found was that decision aids not only improve the individual’s knowledge of their options, including the benefits and harms of those options, but decision aids also assist people in reaching choices that are more consistent with their informed values, while fostering collaboration with their provider.
A sleeper provision of the Affordable Care Act (ACA) encourages greater use of shared decision making in health care. For many health situations in which there's not one clearly superior course of treatment, shared decision making can ensure that medical care better aligns with patients' preferences and values. One way to implement this approach is by using patient decision aids -- written materials, videos, or interactive electronic presentations designed to inform patients and their families about care options; each option's outcomes, including benefits and possible side effects; the health care team's skills; and costs. Shared decision making has the potential to provide numerous benefits for patients, clinicians, and the health care system, including increased patient knowledge, less anxiety over the care process, improved health outcomes, reductions in unwarranted variation in care and costs, and great alignment of care with patients' values.
