They Came, But Will They Come Back? An Observational Study of Re-Enrollment Predictors for the Oklahoma Tobacco Helpline.

Purpose: Although quitlines reach 1% to 2% of tobacco users annually, additional efforts are needed to increase their impact. We hypothesized that offering less intensive services would increase the rate of re-enrollment in any service, as well as re-enrollment in more intensive services. This study describes the enrollment patterns and identifies re-enrollment predictors for Oklahoma Tobacco Helpline (OTH) participants.
