Assessing the Impact of Patient Decision Aids on Health Care Utilization and the Costs of Care

×

Evidence suggests that by aligning medical treatment options more closely with the informed preferences of patients, we can encourage more appropriate use of services in the United States. Because they can help patients make informed choices, patient decision aids—evidence-based tools used to facilitate shared decision-making—hold promise to reduce unwarranted regional variations in treatment for preference-sensitive medical conditions. This project will evaluate the impact of implementation of patient decision aids throughout Group Health's extensive network of physician group practices in Washington State. Using a comparison group, the investigators will assess the differential effect of decision aids on the use of 12 elective surgical procedures, total health care utilization, and total costs.
