Paying Low-Income Smokers to Quit? New Study Shows Financial Incentives for Tobacco Quit Phone Line Engagement Are Cost-Effective
Newswise — Lawrenceville, NJ, USA—February 12, 2019—Value in Health, the official journal of ISPOR—the professional society for health economics and outcomes research, announced today the publication of new research showing that the use of financial incentives to encourage engagement with tobacco quit line treatment is a cost-effective option to enhance smoking cessation rates for low-income smokers. The report, “Paying Low-Income Smokers to Quit? The Cost-Effectiveness of Incentivizing Tobacco Quit Line Engagement for Medicaid Recipients Who Smoke,” was published in the February 2019 issue of Value in Health.
Researchers from the University of Wisconsin School of Medicine and Public Health evaluated the cost-effectiveness of financial incentives to encourage low-income smokers to engage in counseling calls with a tobacco quit phone line. Eligible smokers were randomized to either an incentive or a control group. All participants were offered 5 smoking cessation counseling calls and received payment for completing a baseline assessment ($40) and a 6-month assessment ($40). Incentive group participants also received compensation for taking counseling calls ($30/call) and for biochemically verified abstinence at the 6-month visit ($40).
Compared with those in the control group, participants in the incentive group engaged in more quit line calls (mean of 3.8 calls vs 2.9 call in the control group) and had higher biochemically verified abstinence at 6-month follow-up (21.6% incentive vs 13.8% control). The differential effectiveness of the financial incentive intervention was 7.9%.
Furthermore, the intervention was cost-effective. The incremental cost-effectiveness ratio (ie, the cost of 1 additional smoker achieving abstinence) was calculated as $2316. This compares favorably with other smoking treatments, such as varenicline combined with proactive telephone counseling, whose incremental cost-effectiveness ratio has been estimated at $2600 per additional smoker who quits.
“Approximately 25% of adult US residents living below the poverty line smoke—a rate substantially higher than the overall adult rate of about 15.5%,” said author Marlon Mundt, PhD, Department of Family Medicine and Community Health, University of Wisconsin School of Medicine and Public Health, Madison, WI, USA. “To date it has been difficult to increase low-income smokers’ participation in evidence-based smoking cessation treatments and improve their quitting success rates. In this study, participants in the incentive group engaged in more quit line calls and had higher abstinence rates at follow-up. Our overall finding was that financial incentives for tobacco quit line engagement are cost-effective for smokers who are Medicaid recipients, illustrating that incentivizing engagement with treatment counselors is a viable option to increase the number of abstainers among low-income smokers.”
