Re-engagement of Low-Income Smokers in Quitline Services: Effects of Incentives and Method of Contact
Menée sur la période 2014-2015 auprès de 5 200 fumeurs ayant déjà eu recours à un service téléphonique d'aide au sevrage tabagique, cette étude analyse l'effet, sur la réinscription au service d'aide, d'une incitation financière chez les personnes à faible revenu
Financial incentives have been shown to improve recruitment of low-income smokers into tobacco quitline services and to improve cessation outcomes. The present study evaluated their use to re-engage low-income smokers who had already used a quitline.Randomly selected Medicaid smokers (N=5,200) who had previously enrolled in a quitline were stratified by time since enrollment (3, 6, 9, or 12 months) and randomly assigned in a 2x4 factorial design to receive, by mail or telephone, an invitation to re-engage, with an offer of no financial incentive or $10, $20, or $40. The primary outcome measure was re-engagement, defined as use of an additional evidence based quitline service within 90 days. Data were collected from May 2014 to October 2015 and analyzed in 2022.Of 5,200 participants invited to re-engage in quitline services, 9.3% did so within 90 days, compared to 6.3% of a randomly selected comparison group (n=22,614, p<0.0001). Letters resulted in greater re-engagement than calls (10.9% vs. 7.8%, respectively, p=0.0001). Among letters, there was a dose-response relationship between incentive level and re-engagement rates (p=0.003). Re-engagement decreased as time since enrollment increased, from 13.7% at 3 months to 5.7% at 12 months (all p’s<0.0001).Low-income smokers who previously used quitline services can be motivated to re-engage in treatment. Mailed letters and automated calls are effective re-engagement strategies. Financial incentives can increase the effectiveness of re-engagement letters. Inviting Medicaid smokers to re-engage with quitline treatment may help to address socioeconomic health disparities and should be standard practice.Nicotine addiction is a chronic relapsing disorder, yet most cessation services are designed to help smokers through only one quit attempt. Smoking is increasingly concentrated in populations with physical and psychological co-morbidities, which can make quitting more difficult and impact whether smokers reach out for additional help following relapse. This study examined whether the timing, method, and content of an offer for further assistance influenced re-engagement rates for a vulnerable population of smokers—Medicaid beneficiaries. Relapsing smokers are responsive to re-engagement offers as early as three months, but there is a closing window of opportunity to reach them.
