Study Summary
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.
Primary Outcome
This outcome will be based on intervention process data. Note that we will measure both offering and accepting referral, but our outcome will be accepting referral.
