Benefits of smoking cessation with focus on cardiovascular and respiratory comorbidities

Smoking cessation is crucial in preventing premature morbidity, disability and mortality worldwide. The effectiveness of quitting tobacco use surpasses any other intervention to minimise the risk for chronic cardiac and respiratory conditions. The overall health benefits of smoking cessation have been recognised for decades but as tobacco legislation has been changing in recent years, new evidence particularly concerning the effect of less smoke exposure on the vascular system has emerged. Recently, much research in chronic obstructive pulmonary disease (COPD) has concerned the ongoing inflammation - also in former smokers - and disease heterogeneity, which provides new knowledge regarding current and ex-smokers with COPD. Many other cardiovascular and respiratory diseases are associated with smoking, and the course of these diseases is not always studied in the context of smoking cessation versus continued smoking. This review summarises the latest available data on health benefits of smoking cessation with focus on both common and infrequent cardiovascular and respiratory diseases.

A clinical practice guideline for treating tobacco use and dependence: 2008 update. A U.S. Public Health Service report

OBJECTIVE

To summarize the U.S. Public Health Service guideline Treating Tobacco Use and Dependence: 2008 Update, which provides recommendations for clinical interventions and system changes to promote the treatment of tobacco dependence.

PARTICIPANTS

An independent panel of 24 scientists and clinicians selected by the U.S. Agency for Healthcare Research and Quality on behalf of the U.S. Public Health Service. A consortium of eight governmental and nonprofit organizations sponsored the update.

EVIDENCE

Approximately 8700 English-language, peer-reviewed articles and abstracts, published between 1975 and 2007, were reviewed for data that addressed assessment and treatment of tobacco dependence. This literature served as the basis for more than 35 meta-analyses.

CONSENSUS PROCESS

Two panel meetings and numerous conference calls and staff meetings were held to evaluate meta-analyses and relevant literature, to synthesize the results, and to develop recommendations. The updated guideline was then externally reviewed by more than 90 experts, made available for public comment, and revised.

CONCLUSIONS

This evidence-based, updated guideline provides specific recommendations regarding brief and intensive tobacco-cessation interventions as well as system-level changes designed to promote the assessment and treatment of tobacco use. Brief clinical approaches for patients willing and unwilling to quit are described.

Helping hospital patients quit: what the evidence supports and what guidelines recommend

OBJECTIVE

The study aimed to critically appraise the extent and strength of systematic review evidence for, and guideline recommendations regarding hospital smoking cessation interventions.

METHODS

Systematic reviews of smoking cessation interventions were identified via an electronic search of the Cochrane Library. Meta-analyses from Cochrane reviews were categorised as those that incorporated only studies of hospital based interventions, and those which incorporated interventions which were not hospital based. Smoking cessation guidelines for hospital health professionals were identified via a search of the World Wide Web.

RESULTS

The review found that evidence from meta-analyses restricted to hospital studies was insufficient to evaluate a number of specific intervention strategies and at times conflicted with the findings of meta-analyses without such restrictions. The majority of guidelines recommended the provision of brief advice, counseling, nicotine replacement therapy despite the absence of clear supporting evidence.

CONCLUSIONS

Further hospital-based research addressing specific cessation strategies is required. Furthermore, smoking cessation guidelines for hospital based health professionals should more specifically reflect evidence from this setting.

Self-reported smoking cessation interventions were not associated with quitting in older women

OBJECTIVE

To determine the extent to which smoking cessation interventions are used in the community and their relative success in older women.

STUDY DESIGN AND SETTING

Prospective cohort study located in 23 general practices in England, Scotland. and Wales and including 3,622 women aged 60 to 79 years at recruitment from the British Women's Heart and Health Study.

RESULTS

Of the 370 smokers at baseline, 77 (21%) had stopped smoking at 3 years, reducing the prevalence of smoking from 10.2% to 8.8%. Women who were light smokers (<10 per day) at baseline were more likely to have quit than heavier smokers. The most common interventions reported by women who smoked at baseline were advice from a general practitioner (GP), family or friend's advice, and use of nicotine replacement, but 42% of the women reported having no intervention to help them to stop smoking. None of the individual interventions were associated with increased odds of quitting smoking over the follow-up period. Women reported finding a GP's advice, referral to a clinic, and nicotine replacement more useful than complementary treatments (acupuncture and hypnotherapy) or advice from family and friends.

CONCLUSION

Smoking cessation rates in this study were in line with national targets and surveys. Self-reports of ever receiving interventions were not associated with quitting smoking among these older women. Different and innovative approaches to smoking cessation may need to be developed, and evaluated in future randomized clinical trials, for individuals who have smoked for a long period of time and for whom other smoking cessation interventions have not proved successful.

Determinants of adoption of cognitive behavioral interventions in a hospital setting: example of a minimal-contact smoking cessation intervention for cardiology wards

OBJECTIVE

The aim of our study was to identify the psychological and organizational determinants of adopting a smoking cessation intervention in cardiology wards, using the Integrated Change Model (I-Change Model) as the theoretical basis.

METHODS

A cross-sectional survey by means of questionnaires was conducted among the heads of all 121 cardiology wards in Dutch hospitals, of whom 77 (64%) responded.

RESULTS

Adopters had a significantly lower level of formalization and more nurses working on the ward. Adopters also had a significantly more positive attitude towards working with the intervention, perceived more positive social influences from their direct environment and had higher self-efficacy. Psychological determinants explained adoption to a greater extent than organizational determinants did.

CONCLUSION

It is very important to take psychological factors into account when studying the adoption of preventive innovations and developing diffusion strategies.

PRACTICE IMPLICATIONS

Programs for dissemination of preventive innovations in a hospital setting should primarily focus on psychological characteristics like social influence and self-efficacy.
