Description
Summary:Low-dose computed tomography (LDCT) screening in high-risk individuals reduces lung cancer (LC) mortality. To inform the implementation of a provincial LC screening program, Ontario Health undertook a Pilot study, which integrated smoking cessation (SC). The impact of integrating SC into the Pilot was assessed by: rate of acceptance of a SC referral; proportion of individuals who were currently smoking cigarettes and attended a SC session; the quit rate at one year; change in the number of quit attempts; change in Heaviness of Smoking Index (HSI); and relapse rate in those who previously smoked. 7,768 individuals were recruited predominantly through primary care physician referral. 4,463 were currently smoking and were risk assessed and referred to SC services, irrespective of screening eligibility: 3,114 (69.8%) accepted referral to an in-hospital SC program, 431 (9.7%) to telephone quit lines and 50 (1.1%) to other programs. 4.4% reported no intention to quit and 8.5% were not interested in participating in a SC program. Of the 3,063 screen eligible individuals who were smoking at baseline LDCT scan, 2,736 (89.3%) attended in-hospital SC counselling. The quit rate at one year was 15.5% (95% CI:13.4 - 17.7%; range, 10.5% to 20.0%). Improvements were also observed in HSI (p< 0.0001), number of cigarettes smoked per day (p< 0.0001), time to first cigarette (p
