          Abstract

          Background

          English Stop Smoking Services primarily deliver behavioural interventions to support abrupt quit attempts. Recent evidence suggests an alternative approach could be offered to clients involving a more gradual reduction of cigarettes smoked leading to complete abstinence, known as ‘Cut Down To Stop’ (CDTS). The purpose of this study was to explore the experiences of stop smoking practitioners and service users who participated in a pilot study of a CDTS service.

          Methods

          The CDTS intervention was pilot tested in a Stop Smoking Service in London, England. As part of the CDTS intervention clients who were still smoking 2 weeks after their quit date were offered tailored advice, medication and support to reduce their current smoking by half, with the aim to stop smoking altogether within a six-month period. A qualitative evaluation was conducted involving a focus group discussion with nine practitioners involved in the delivery of the CDTS intervention and telephone interviews with 18 CDTS service users. Thematic analysis was performed.

          Results

          Service users and practitioners were very positive about their experience with the CDTS intervention. The intervention was found to be an effective way of keeping clients engaged with the service and was felt to increase the likelihood they might quit and/or re-engage in service for future quit attempts. Elements that contributed to the attractiveness of the CDTS intervention included: 1) the trust and empathetic relationship developed between service users, practitioners and their referring primary care provider; 2) time and flexibility for service users to engage in the quitting process at their own pace; 3) setting progressive goals and building service user confidence; 4) the opportunity to experiment with quit smoking medications; and, 5) the on-going contact with the practitioner/service.

          Conclusions

          Service users who are not successful with quitting abruptly may benefit from a CDTS intervention. This study highlights the important role of ‘relationships’, time and ‘flexible’ service delivery models in engaging service users who are not initially successful with quitting. The findings of this study have the potential to inform decision-making regarding the value of the CDTS approach for the English Stop Smoking Service and cessation services worldwide.

          Performance of English stop smoking services in first 10 years: analysis of service monitoring data.

          To analyse the performance of the English Stop Smoking Services from 2001/02 to 2010/11. Analysis of national service monitoring data. England. Smokers recorded as having been treated by English stop smoking services between April 2001 and March 2011. Annual figures for the number of quit dates set (throughput), the percentage of these that led to biochemically verified abstinence after four weeks (four week quit rate), and the "impact" in terms of the number of four week quitters beyond those who it is estimated would have stopped with only a prescription for smoking cessation treatment; characteristics of smokers being treated, medication used, and mode of delivery (for example, one to one, group based); variability across local services in throughput, four week quit rates, and impact for 2010/11. Throughput rose from 227,335 in 2001/02 to 787,527 (8% of all smokers) in 2010/11. The percentage of four week quitters declined slightly from 35% to 34%. Impact rose from 22,933 four week quitters created in 2001/02 to 72,411 in 2010/11 (corresponding to an estimated 21,723 12 month quitters). The services were successful in reaching disadvantaged smokers; 54% (n = 425,684) were in receipt of free prescriptions in 2010/11. Substantial variation existed across local services in throughput, success rates, and impact. The English stop smoking services have had an increasing impact in helping smokers to stop in their first 10 years of operation and have successfully reached disadvantaged groups. However, performance across local services has varied considerably.

            Relapse prevention in UK Stop Smoking Services: current practice, systematic reviews of effectiveness and cost-effectiveness analysis.

            Reducing smoking is a chief priority for governments and health systems like the UK National Health Service (NHS). The UK has implemented a comprehensive tobacco control strategy involving a combination of population tobacco control interventions combined with treatment for dependent smokers through a national network of NHS Stop Smoking Services (NHS SSS). To assess the effectiveness and cost-effectiveness of relapse prevention in NHS SSS. To (1) update current estimates of effectiveness on interventions for preventing relapse to smoking; (2) examine studies that provide findings that are generalisable to NHS SSS, and which test interventions that might be acceptable to introduce within the NHS; and (3) determine the cost-effectiveness of those relapse preventions interventions (RPIs) that could potentially be delivered by the NHS SSS. A systematic review of the literature and economic evaluation were carried out. In addition to searching the Cochrane Tobacco Addiction Group register of trials (2004 to July 2008), MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, the Science Citation Index and Social Science Citation Index were also searched. The project was divided into four distinct phases with different methodologies: qualitative research with a convenience sample of NHS SSS managers; a systematic review investigation the efficacy of RPIs; a cost-effectiveness analysis; and a further systematic review to derive the relapse curves for smokers receiving evidence-based treatment of the type delivered by the NHS SSS. Qualitative research with 16 NHS SSS managers indicated that there was no shared understanding of what relapse prevention meant or of the kinds of interventions that should be used for this. The systematic review included 36 studies that randomised and delivered interventions to abstainers. 'Self-help' behavioural interventions delivered to abstainers who had achieved abstinence unaided were effective for preventing relapse to smoking at long-term follow-up [odds ratio (OR) 1.52, 95% confidence interval (CI) 1.15 to 2.01]. The following pharmacotherapies were also effective as RPIs after their successful use as cessation treatments: bupropion at long-term follow-up (pooled OR 1.49, 95% CI 1.10 to 2.01); nicotine replacement therapy (NRT) at medium- (pooled OR 1.56, 95% CI 1.16 to 2.11) and long-term follow-ups (pooled OR 1.33, 95% CI 1.08 to 1.63) and one trial of varenicline also indicated effectiveness. The health economic analysis found that RPIs are highly cost-effective. Compared with 'no intervention'; using bupropion resulted in an incremental quality-adjusted life-year (QALY) increase of 0.07, with a concurrent NHS cost saving of 68 pounds; for NRT, spending 12 pounds resulted in a 0.04 incremental QALY increase; varenicline resulted in a similar QALY increase as NRT, but at almost seven times the cost. Extensive sensitivity analyses demonstrated that cost-effectiveness ratios were more sensitive to variations in effectiveness than cost and that for bupropion and NRT, cost-effectiveness generally remained. Varenicline also demonstrated cost-effectiveness at a 'willingness-to-pay' threshold of 20,000 pounds per QALY, but exceeded this when inputted values for potential effectiveness were at the lower end of the range explored. For all drugs, there was substantial relapse to smoking after treatment courses had finished. Quit attempts involving NRT appeared to have the highest early relapse rates, when trial participants would be expected to still be on treatment, but for those involving bupropion and varenicline little relapse was apparent during this time. The qualitative research sample was small. Based on the totality of evidence, RPIs are expected to be effective and cost-effective if incorporated into routine treatment within the NHS SSS. While staff within the NHS SSS were largely favourably inclined towards providing RPIs, guidance would be needed to encourage the adoption of the most effective RPIs, as would incentives that focused on the importance of sustaining quit attempts beyond the currently monitored 4-week targets.

              Using text messaging to prevent relapse to smoking: intervention development, practicability and client reactions.

              The NHS Stop Smoking Service (NHS-SSS) helps approximately half its clients to quit for 4 weeks. However, most initially successful quitters relapse within 6 months. Short message service (SMS) texting has been shown to facilitate stopping smoking. We describe the development, implementation and subsequent evaluation, in terms of practicability and client response, of an SMS text-based relapse prevention intervention (RPI) delivered within routine community and specialist National Health Service (NHS) Stop Smoking Service (SSS) provision in four Primary Care Trusts. Text messages aimed at motivation to remain abstinent, preventing careless lapses and continuing the full course of medicine for smoking cessation were developed and sent weekly to clients' mobile phones for 12 weeks and fortnightly for 6 months. They were asked to respond to some of the texts and contact the NHS SSS if they lapsed. They were also offered free nicotine mini lozenges to be sent via the mail on three occasions. NHS SSS. 202 clients who had been abstinent for 4 weeks. Feasibility of introducing RPI into routine care; response to interactive messages and requests for the medication; rating of the helpfulness of RPI; self-reported and carbon monoxide (CO)-validated smoking status for up to 26 weeks. A text-based RPI was easy to implement within the NHS SSS provided by specialist advisers, but enrollment of clients from services provided by a network of pharmacists was difficult because client contact details were often lacking. Where records of the number of people invited to RPI were available, 94% of eligible participants enrolled. The RPI was well received by both SSS clients and staff, with 70% (n = 63) of clients who completed follow-up considering the intervention helpful. Eighty-five per cent (n = 172) of clients responded to at least one of the nine interactive text messages. Sixty-four clients (32% of the total, 47% of those we managed to contact) reported continuous abstinence at 6 months. Eighteen (9%) clients who relapsed to smoking used the RPI to re-engage with the NHS SSS and 10 (5%) successfully re-established abstinence. In smokers attending National Health Service Stop Smoking Services who are abstinent 4 weeks after their quit date, a relapse prevention intervention based on SMS text messaging was well received, and can be implemented economically and rapidly. A controlled trial is needed to establish whether it has a significant impact on relapse. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.
