Effectiveness of smoking cessation interventions for smokers with chronic diseases: A systematic review

다국어 초록 (Multilingual Abstract)

To systematically summarize seminal studies on the design and effectiveness of smoking cessation interventions targeted at patients with chronic diseases through a critical appraisal of the literature.
A systematic review.
This review included literature identified through a search of six databases up to June 2020.
This review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions. The literature search was limited to English‐language articles on the effectiveness of smoking cessation interventions for smokers who were aged ≥18 years and diagnosed with chronic diseases. Data were extracted using the Cochrane Data collection form for intervention reviews of randomized controlled trials and non‐randomized controlled trials. The articles were subjected to a quality assessment.
Ten relevant articles were identified. The designs of the interventions were highly heterogeneous, and only six articles reported a significant increase in smoking abstinence among patients with chronic diseases. In the target population, an intervention delivered by healthcare professionals on an intensive schedule was shown to more effectively induce smoking cessation, compared with minimal counselling. However, methodological flaws were identified in most of the included studies.
The findings of this review suggest that additional efforts are needed to design smoking cessation interventions for patients with chronic diseases and that further examination of the effectiveness and feasibility of these interventions is warranted.

What problem did the study address?


This review evaluated the effectiveness of smoking cessation interventions targeted at patients with chronic diseases.



What were the main findings?


An intervention with an intensive schedule that was delivered by healthcare professionals was shown to more effectively induce smoking cessation in patients with chronic diseases, compared with minimal counselling.

More attention and resources should be directed towards smokers with no intention to quit, especially those with chronic diseases.

There is an urgent need for generic smoking cessation interventions that use novel approaches to address the unique needs of this population and to integrate such evidence‐based interventions into routine care.



Where and on whom will the research have impact?


The findings of this review may guide nurses, who play a prominent role in raising the issue of smoking cessation with patients, to design appropriate smoking cessation interventions for patients with chronic diseases.

The resulting improvements in patients’ health would not only benefit patients themselves but also reduce the burden of chronic diseases on healthcare systems.
