Many smokers do not use existing free or low-cost smoking cessation services, cost-effective interventions to increase use are needed.
We did a 2-armed cluster randomised controlled trial (cRCT) in Hong Kong, China, to evaluate the effectiveness of active referral plus a small financial incentive on abstinence. Chinese adult smokers who smoked at least 1 cigarette per day were proactively recruited from 70 community sites (clusters). Random allocation was concealed until the recruitment started. The intervention group received an offer of active referral to cessation services at baseline plus an incentive (HK$300/US$38) after using any cessation services within 3 months. The control group received general brief cessation advice. The primary outcomes were biochemically validated abstinence at 3 and 6 months. Operating costs in real-world implementation was calculated. Trial Registry: ClinicalTrials.gov NCT03565796.
Between June and September 2018, 1093 participants were randomly assigned to the intervention (n=563) and control (n=530) groups. By intention-to-treat, the intervention group showed higher validated abstinence than the control group at 3 months (8.4% vs. 4.5%, risk ratio [RR] 1.88, 95% CI 1.01-3.51, =0.046) and 6 months (7.5% vs. 4.5%, RR 1.72, 95% CI 1.01-2.93, =0.046). Average cost per validated abstinence was lower in the intervention (US$ 421) than control (US$ 548) group.
This cRCT has first shown that a simple, brief, and low-cost intervention with active referral plus a small monetary incentive was effective in increasing smoking abstinence and smoking cessation service use in community smokers.

许多吸烟者未使用现有的免费或低成本戒烟服务，因此需要采取具有成本效益的干预措施来提高使用率。
我们在中国香港进行了一项双臂整群随机对照试验（cRCT），以评估主动转诊加小额经济激励对戒烟的有效性。从70个社区场所（群组）中主动招募了每天至少吸1支烟的中国成年吸烟者。随机分配在招募开始前一直保密。干预组在基线时获得主动转诊至戒烟服务的机会，并在3个月内使用任何戒烟服务后获得一笔激励金（300港元/38美元）。对照组接受一般性简短戒烟建议。主要结局是3个月和6个月时经生化验证的戒烟情况。计算了实际实施中的运营成本。试验注册：ClinicalTrials.gov NCT03565796。
2018年6月至9月期间，1093名参与者被随机分配到干预组（n = 563）和对照组（n = 530）。按意向性分析，干预组在3个月时经验证的戒烟率高于对照组（8.4%对4.5%，风险比[RR]1.88，95%CI 1.01 - 3.51，P = 0.046），6个月时也是如此（7.5%对4.5%，RR 1.72，95%CI 1.01 - 2.93，P = 0.046）。干预组每例经验证戒烟者的平均成本（421美元）低于对照组（548美元）。
这项cRCT首次表明，一种简单、简短且低成本的干预措施，即主动转诊加小额金钱激励，在提高社区吸烟者的戒烟率和戒烟服务使用率方面是有效的。
