Implications for practice and research

  • Hospital-initiated smoking cessation intervention, continued postdischarge for at least 1 month, should become standard practice in all (general) hospital settings.

  • A smoking cessation intervention should be initiated with every smoker during a hospital stay.

  • An important yet neglected area of research is the effectiveness of smoking cessation interventions initiated within psychiatric hospital settings.

Context

The provision of a smoking cessation intervention in all clinical healthcare settings has been strongly recommended by expert international reviews.1 The aim of this review was to determine the effectiveness of smoking cessation interventions initiated in the hospital setting, building on an earlier 2007 review.2

Methods

A systematic review was conducted, including randomised and quasi-randomised trials of any intervention (conducted or initiated within hospital settings) to help patients stop smoking. Fifty trials were included, of which 42 incorporated postdischarge support. The review also included sensitivity analyses to explore subgroupings of interventions, settings and patient diagnoses.

Findings

Results indicated that smoking cessation interventions delivered in the hospital setting with at least 1-month postdischarge support increased cessation rates by 37% at 6–12 months follow-up. This result was not significantly different for patients with varying diagnoses, or those attending acute versus rehabilitation facilities. No evidence was found for the effectiveness of less intensive interventions, or interventions without postdischarge support. Adding nicotine replacement therapy to a counselling intervention significantly increased cessation rates by 54%; with insufficient evidence found to support the efficacy of adding bupropion or varenicline.

Commentary

This is a comprehensive and timely review with clear clinical implications related to the provision of smoking cessation interventions for hospitalised smokers. Important gaps in research were also identified.

Interestingly, while the authors acknowledge the opportunity afforded by smoke-free hospital settings to provide tobacco-dependence treatments for hospitalised smokers, no reference is made to the ‘smoke-free status’ of the hospital settings within the included trials. Some evidence suggests that abstaining from tobacco during a hospital admission can in and of itself significantly improve cessation rates at 6-month follow-up, and that reductions in cigarette consumption may occur postdischarge even for smokers who do not abstain during hospitalisation.3 It would be valuable if a review such as this included the nature of smoking bans, adherence with them and the extent to which nicotine-dependence treatment was provided to patients as a matter of routine care.

This review excluded psychiatric and substance use facilities; two settings where smoking rates and nicotine-dependence levels are disproportionately high,4 and where the patient populations are especially likely to suffer smoking-related morbidity and mortality.5 While the authors provide no rationale for this, it seems likely that the dearth of research investigating the effectiveness of smoking cessation interventions within such settings necessitated exclusion. It is important that research begins to address the question of the effectiveness of smoking cessation interventions initiated within psychiatric hospital settings; the same sound arguments for the delivery of a smoking cessation intervention to hospitalised smokers generally apply no less to patients hospitalised within psychiatric facilities. As in general hospital settings, high rates of relapse following discharge from a smoke-free psychiatric hospital6 suggest the need for intensive cessation support to be continued to the community setting. The first rigorous controlled trials of smoking cessation interventions initiated within psychiatric hospital settings are in progress.7 ,8

Finally, a sensitivity analysis conducted as part of this review excluded trials in which patients were selected on the basis of their motivation to quit. This resulted in no change to the intervention effect relative to the control group. This highlights the importance of offering smoking cessation support to all hospitalised smokers, regardless of their stated or assumed intent to quit at the time.
