Introduction: Financial incentives to stop smoking (FISS) programs have been implemented internationally to encourage people who smoke to quit smoking. However, such programs require that the financial reward structure and its resulting effects on smoking quit rates are considered. We analyzed a number of scenarios for FISS reward schedules for current smoking individuals in Ireland, with a view to identify the potential implications in terms of financial consequences and expected effects. Methods: Using national QuitManager services data 2021–2023, we defined smoking quit rates for smokers currently using the national Health Services Executive stop smoking services in Ireland. Smoking quit rates at 4, 12 and 52 weeks were defined, and additionally defined by sex, age and education level. Using scenarios assuming different FISS reward sizes, structures and targeted population sub-groups, we estimated the number of additional quitters, budget impact, and incremental costeffectiveness ratio. Results: A FISS program, if implemented for a cohort of 3500 smokers can result in a budget impact ranging €250000 – €870000. The cost-effectiveness trade-off between different payment schedules and the expected effect size suggested that FISS are cost-effective even at a moderate effect size. A FISS program implemented to approximately 20000 smokers nationally would cost between €2.0 million and €4.8 million, subject to the chosen reward schedule. Across social groups, FISS is more cost-effective for females, individuals in the youngest age group, and individuals with a medium level of education. Conclusions: This analysis highlights the importance of considering different FISS schedules and potential quit effects, when designing such programs. We highlight that FISS programs should be targeted at certain social groups to achieve highest long-term smoking cessation rates. We also identified important challenges that decision-makers face when designing the reward structure of FISS programs. The acceptability or otherwise of the FISS structures may differ among stakeholders and should be explored. [ABSTRACT FROM AUTHOR]

Introduction: Differences in smoking prevalence across socioeconomic groups are a major driver of health inequalities. Although smoking prevalence continues to decline across most developed countries, socioeconomic inequalities in smoking still persist. While Ireland is among a small number of countries with a tobacco-endgame goal set to achieve a smoking prevalence of 5% by 2025, the challenge this presents by socioeconomic status is uncharted., Aims and Methods: We analyzed how differences in smoking status across various socioeconomic groups have changed over time in the adult population in Ireland. We used cross-sectional smoking data from the national population-based Healthy Ireland Survey for 2015-2022 (n = 52 494). Educational attainment and area-based deprivation were used as socioeconomic indicators. Socioeconomic differences and changes in inequality over time were identified using the relative index of inequality (RII). Multinomial logistic regression was used to analyze the association between socioeconomic status and daily smoking, occasional smoking, former smoking, and never smoking with adjustment for sex, age, and survey year., Results: We observed the highest daily smoking rates among the least educated (OR = 11.62; 95% CI = 9.91, 13.63) and individuals living in the most deprived areas (OR = 4.23; 95% CI = 3.55, 5.04). Additionally, we identified significant relative smoking inequalities over the observation period continued to increase, among the least educated (RII = 2.86, 95%CI = 2.63, 3.09) and individuals living in the most deprived areas (RII = 2.64, 95% CI = 2.36, 2.93)., Conclusions: Despite generally reducing smoking prevalence, socioeconomic inequalities continue to widen among the smoking population in Ireland., Implications: As the tobacco endgame deadline of 2025 is fast approaching, this study highlights the urgent need to consider potential effects across the lowest socioeconomic status groups when implementing equity-oriented tobacco control policies., (© The Author(s) 2024.
