Input: Fifty-eight studies met the inclusion criteria, nine of which are new for this update. Pooling 44 studies (over 20,000 participants) comparing a nursing intervention to a control or to usual care, we found the intervention increased the likelihood of quitting (RR 1.29, 95% CI 1.21 to 1.38); however, statistical heterogeneity was moderate (I2 = 50%) and not explained by subgroup analysis. Because of this, we judged the quality of evidence to be moderate. Despite most studies being at unclear risk of bias in at least one domain, we did not downgrade the quality of evidence further, as restricting the main analysis to only those studies at low risk of bias did not significantly alter the effect estimate. Subgroup analyses found no evidence that high-intensity interventions, interventions with additional follow-up or interventions including aids that demonstrate the pathophysiological effect of smoking are more effective than lower intensity interventions, or interventions without additional follow-up or aids. There was no evidence that the effect of support differed by patient group or across healthcare settings. There is moderate quality evidence that behavioural support to motivate and sustain smoking cessation delivered by nurses can lead to a modest increase in the number of people who achieve prolonged abstinence. There is insufficient evidence to assess whether more intensive interventions, those incorporating additional follow-up, or those incorporating pathophysiological feedback are more effective than one-off support. There was no evidence that the effect of support differed by patient group or across healthcare settings.
Output:

This review of clinical trials covered 58 studies in which nurses delivered a stop-smoking intervention to smokers. More than 20,000 participants were included in the main analysis, including hospitalized adults and adults in the general community. The most recent search was conducted in January 2017. All studies reported whether or not participants had quit smoking at six months or longer. This review found moderate-quality evidence that advice and support from nurses could increase people's success in quitting smoking, whether in hospitals or in community settings. Eleven studies compared different nurse-delivered interventions and did not find that adding more components changed the effect. The quality of evidence was moderate, meaning that further research may change our confidence in the result. This is because results were not consistent across all of the studies, and in some cases there were not very many studies contributing to comparisons.
