Effects of Provider Commitments to Choose Wisely

Study Overview
=================
Brief Summary
-----------------
Clinicians' decisions to order potentially unnecessary services -- such as those targeted in the Choosing Wisely® campaign -- are often affected by their high-pressure practice environments, which can make it hard to consistently avoid ordering low-value care. The field of behavioral economics offers a promising and highly scalable approach to decreasing use of low-value services: asking clinicians to commit to avoid ordering such services and providing them and their patients with resources to support adherence to this commitment. This project will evaluate the effects of such an intervention across 2 large health systems, Michigan Medicine and IHA, through a mixed-methods, stepped wedge cluster randomized trial. In each of the study clinics, clinicians will be invited to commit to following a set of targeted Choosing Wisely® recommendations. Clinicians who make such a commitment, and their patients, will receive access to key resources to support adherence to this commitment. To measure the effects of the intervention, automated clinical data and medical record data before and after the intervention will be examined. Surveys and semi-structured interviews of both clinicians and patients will also be conducted to determine the effects of the intervention on their decision-making and experiences.

Detailed Description
-----------------
A mixed-methods stepped wedge cluster randomized trial will be conducted in 8 primary care clinics of IHA, a private multispecialty group practice, and Michigan Medicine, a large academic health system. The study will test whether pre-encounter clinician commitments combined with patient and provider supports decrease overtreatment of type 2 diabetes among patients 65 and older, use of benzodiazepines and sedative-hypnotics among patients age 65 and older who have insomnia or anxiety, and use of PSA tests to screen for prostate cancer among men 75 and older. These 3 recommendations were chosen because they are commonly performed in primary care practice, have Choosing Wisely® recommendations against these low-value services, and represent situations in which clinician decisions about ordering of services can be unduly swayed by interactions with patients.
