The aim of this systematic review is to establish the most effective stop smoking intervention approach for smokers with COPD. The search strategy included the electronic databases MEDLINE, EMBASE, AMED, PsycINFO, DARE, Cochrane Library, and CINAHL, between January 2006 and January 2010. References of the included studies were also screened for additional papers, and further hand searches were conducted. The selection criteria included randomized controlled trials or quasi-randomized controlled trials with at least one subject group diagnosed with COPD. Two independent reviewers reviewed the included studies, using a quality assessment form developed from the selection criteria. Divergence of quality assessment scores was resolved by the 2 reviewers agreeing on a score. The 4 studies selected indicate that psychosocial interventions combined with pharmacotherapy are effective in smoking cessation at 12 months post-intervention, although the effect is not statistically significant, due to small sample size and heterogeneity between the studies (odds ratio 2.35, 95% CI 0.25-21.74,). However, despite this medium effect size, due to a lack of universal use of pharmacotherapies in most of the studies, it makes a definitive comparison of efficacy difficult to determine. This review also shows the effectiveness of psychosocial treatment for people with or without COPD symptoms at 12 months, although the effect of disease severity is not clear. This review also highlights the difficulty of maintaining attendance at community-based locations, compared to acute or research settings.
Objectives A greater proportion of non-pregnant smokers attempted to stop smoking during compared to before the COVID-19 pandemic. The objective of this study was to determine if a greater proportion of pregnant women also attempted to stop smoking during the pandemic rather than before. Methods The use of antenatal smoking cessation services and nicotine replacement therapies (NRT) in pregnant women was audited before (2019–2020) and during the COVID pandemic (2020–2021). Anonymised data from January 2019 to March 2021 were analysed from the Lambeth and Southwark smoking cessation service. Results A total of 252 pregnant women who smoked were referred to their local antenatal smoking cessation service, of which 90 (35.7%) (median age: 31 years [19–52 years]) chose to attend smoking cessation clinics. The COVID-19 pandemic was not associated with an increase in the number of women attending smoking cessation clinics, (2020–2021 n=46 [40.8%] of 110); compared to (2019–2020 n=44 [30.9%] of 142 referred pregnant women pre-pandemic) p=0.061. Eighty-two women utilised NRT to help them stop smoking and the frequency of NRT use did not change during the pandemic (2019–2020 n=39, 2020–2021 n=43; p=0.420). No significant difference in smoking cessation rates between the two periods was observed at either the four-week (p=0.285) or twelve-week follow-up (p=0.829). Conclusions Smoking cessation rates in pregnant women and the demand for antenatal smoking cessation services was unchanged during compared to before the COVID-19 pandemic.
