Comparing an Opt-out to an opt-in Approach for Smoking Cessation in VA Primary Care Clinics

Running, not enrolling · Not applicable

Conditions studied: Tobacco Use

In brief

The investigators propose a Type I hybrid effectiveness/implementation study to evaluate two population-based approaches for increasing use of Quitlines and text messaging at two VA sites. Specifically, the investigators will test the default bias, examining whether an opt-out approach to referral is more effective than an opt-in approach. The investigators will randomly assign teams to either an opt-out or opt-in approach to referring smokers to treatment. In the opt-out approach, the default is that everyone is referred to treatment unless they actively choose not to be. In the opt-in approach, people are offered treatment but must actively choose to enroll in it.
