Guillaumier A, Skelton E, Shakeshaft A, et al. - Researchers conducted cluster-randomized controlled trial from January 2015-March 2016 to examine how an organizational change intervention integrating smoking cessation treatment into usual alcohol and other drug treatment vs usual care affects the following outcomes: 7-day point prevalence abstinence at 8 weeks follow-up; prolonged abstinence; cigarettes smoked per day; number of quit attempts; and offer and use of nicotine replacement therapy. They assessed all outcomes at 8 weeks and 6.5 months follow-up. An independent blinded biostatistician randomized 32 eligible services (provided face-to-face client sessions to ≥ 50 clients/year) in Australia to control (usual care; n = 15) or intervention (n = 17) groups. Outcomes revealed that no significant improvement in short-term abstinence from smoking was achieved when smoking cessation treatment was integrated into addiction services.
