Smoking cessation treatment by Dutch respiratory nurses: reported practice, attitudes and perceived effectiveness

Economic evaluation of a telephone- and face-to-face-delivered counseling intervention for smoking cessation in patients with coronary heart disease

OBJECTIVE

This study examined the cost-effectiveness and cost-utility of two smoking cessation counseling interventions differing in their modality for patients diagnosed with coronary heart disease from a societal perspective.

METHODS

In a randomized controlled trial conducted in Dutch hospital wards, cardiac patients who smoked prior to admission were allocated to usual care (n = 245), telephone counseling (n = 223) or face-to-face counseling (n = 157). The counseling interventions lasted for 3 months and were complemented by nicotine patches. Baseline histories were obtained, and interviews took place 6 months after hospitalization to assess self-reported smoking status and quality adjusted life years (QALYs). Incremental cost-effectiveness ratios per quitter and cost-utility ratios per QALY were calculated and presented in acceptability curves. Uncertainty was accounted for by sensitivity analysis.

RESULTS

Using continued abstinence as the outcome measure showed that telephone counseling had the highest probability of being cost-effective. Face-to-to-face counseling was also more cost-effective than usual care. No significant improvements and differences in QALYs between the three conditions were found. Varying costs and effect estimations revealed that the results of the primary analyses were robust.

CONCLUSIONS

Assuming a willingness-to-pay of €20,000 per abstinent patient, telephone counseling would be a highly cost-effective smoking cessation intervention assisting cardiac patients to quit. However, the lack of consensus concerning the willingness-to-pay per quitter impedes drawing firm conclusions. Moreover, studies with extended follow-up periods are needed to capture late relapses and possible differences in QALYs.

Effectiveness of a telephone delivered and a face-to-face delivered counseling intervention for smoking cessation in patients with coronary heart disease: a 6-month follow-up

Smoking cessation interventions for cardiac patients need improvement given their weak effects on long-term abstinence rates and low compliance by nurses to implementation. This study tested the effectiveness of two smoking cessation interventions against usual care in cardiac patients, and conditional effects for patients' motivation to quit and socio-economic status (SES). An experimental study was conducted from 2009 to 2012 for which Dutch cardiac patient smokers were assigned to: usual care (UC; n = 245), telephone counseling (TC; n = 223) or face-to-face counseling (FC; n = 157). The three groups were comparable at baseline and had smoked on average 21 cigarettes a day before hospitalization. After six months, interviews occurred to assess self-reported smoking status. Patients in the TC and FC group had significantly higher smoking abstinence rates than patients in the UC group (p ≤ 0.05 at all times). Regression analysis further revealed significant conditional effects of the interventions on smoking abstinence in patients with lower SES, with a larger effect for TC than FC when compared to UC. These findings suggest that intensive counseling is effective in increasing short-term abstinence rates, particularly in patients with lower SES. Future studies need to investigate how patients with higher SES can profit equally from these type of interventions.

Smoking cessation treatment practices: recommendations for improved adoption on cardiology wards

BACKGROUND AND OBJECTIVES

Smoking cessation treatment practices described by the 5 A's (ask, advise, assess, assist, arrange) are not well applied at cardiology wards because of various reasons, such as a lack of time and appropriate skills of the nursing staff. Therefore, a simplified guideline proposing an ask-advise-refer (AAR) strategy was introduced in Dutch cardiac wards. This study aimed to identify factors that determine the intentions of cardiac ward heads in adopting the simplified AAR guideline, as ward heads are key decision makers in the adoption of new guidelines. Ward heads' perceptions of current smoking cessation practices at the cardiac ward were also investigated.

METHODS

A cross-sectional survey with written questionnaires was conducted among heads of cardiology wards throughout the Netherlands, of whom 117 (64%) responded.

RESULTS

According to the heads of cardiac wards, smoking cessation practices by cardiologists and nurses were mostly limited to brief practices that are easy to conduct. Only a minority offered intensive counseling or arranged follow-up contact. Heads with strong intentions of adopting the AAR guideline differed significantly on motivational and organizational attributes and perceived more smoking cessation assistance by other health professionals than did heads with weak intentions of adopting. Positive attitudes, social support toward adoption, and perception of much assistance at the ward were significantly associated with increased intentions to adopt the AAR guideline.

CONCLUSIONS

Brief smoking cessation practices are adequately performed at cardiac wards, but the most effective practices, offering assistance and arranging for follow-up, are less than optimal. The AAR guideline offers a more feasible approach for busy cardiology wards. To ensure successful adoption of this guideline, the heads of cardiac wards should be convinced of its advantages and be encouraged by a supportive work environment. Policies may also facilitate the adoption of the AAR guideline.

Effectiveness of two intensive treatment methods for smoking cessation and relapse prevention in patients with coronary heart disease: study protocol and baseline description

BACKGROUND

There is no more effective intervention for secondary prevention of coronary heart disease than smoking cessation. Yet, evidence about the (cost-)effectiveness of smoking cessation treatment methods for cardiac inpatients that also suit nursing practice is scarce. This protocol describes the design of a study on the (cost-)effectiveness of two intensive smoking cessation interventions for hospitalised cardiac patients as well as first results on the inclusion rates and the characteristics of the study population.

METHODS/DESIGN

An experimental study design is used in eight cardiac wards of hospitals throughout the Netherlands to assess the (cost-)effectiveness of two intensive smoking cessation counselling methods both combined with nicotine replacement therapy. Randomization is conducted at the ward level (cross-over). Baseline and follow-up measurements after six and 12 months are obtained. Upon admission to the cardiac ward, nurses assess patients' smoking behaviour, ensure a quit advice and subsequently refer patients for either telephone counselling or face-to-face counselling. The counselling interventions have a comparable structure and content but differ in provider and delivery method, and in duration. Both counselling interventions are compared with a control group receiving no additional treatment beyond the usual care. Between December 2009 and June 2011, 245 cardiac patients who smoked prior to hospitalisation were included in the usual care group, 223 in the telephone counselling group and 157 in the face-to-face counselling group. Patients are predominantly male and have a mean age of 57 years. Acute coronary syndrome is the most frequently reported admission diagnosis. The ultimate goal of the study is to assess the effects of the interventions on smoking abstinence and their cost-effectiveness. Telephone counselling is expected to be more (cost-)effective in highly motivated patients and patients with high SES, whereas face-to-face counselling is expected to be more (cost-)effective in less motivated patients and patients with low SES.

DISCUSSION

This study examines two intensive smoking cessation interventions for cardiac patients using a multi-centre trial with eight cardiac wards. Although not all eligible patients could be included and the distribution of patients is skewed in the different groups, the results will be able to provide valuable insight into effects and costs of counselling interventions varying in delivery mode and intensity, also concerning subgroups.

A national survey of training and smoking cessation services provided in community pharmacies in Thailand

Over the past few years, several training programs have been run in support of smoking cessation services within community pharmacy circles in Thailand. These have included a comprehensive training program offered by the Thai Pharmacy Network for Tobacco Control (TPNTC) and brief training programs run by other agencies. This study provides an estimate of the scale of smoking cessation activities among Thai pharmacies, and examines the impact of both the brief and comprehensive training programs on the provision of smoking cessation services. A self-administered questionnaire was mailed to 3,600 Thai community pharmacists. A total of 1,001 questionnaires were returned (response rate: 27.8%). Smoking cessation services were provided by 71.1% of the respondents, and 47.4% of such services gave only brief advice. Comprehensive services (defined by the 5A's: ask, advise, assess, assist, and arrange follow-up) accounted for 15.3% of the respondents. Only 293 pharmacists (29.6%) said they had received cessation training; 62.5% of whom had received such training from TPNTC. The receipt of brief and comprehensive training was associated with a higher rate of the provision of brief advice, when compared with no training, showing adjusted odds ratios (ORs) of 2.93 (95% CI, 1.66-5.18) and 5.93 (95% CI, 3.18-10.17) respectively, while evidence of differences between these training programs was not observed, having an adjusted OR of 1.94 (95% CI, .89-4.21). TPNTC trained pharmacists were 4.98 times (95% CI, 2.24-11.05) more likely than those who received other brief training to provided the 5A's cessation services. All types of training program help to promote the provision of brief counseling by pharmacists. Comprehensive training is associated with the increased provision of both 4A's and 5A's cessation services.

Effectiveness of Nurse Based Motivational Interviewing for smoking cessation in high risk cardiovascular outpatients: a randomized trial

OBJECTIVE

To evaluate the feasibility and effectiveness of Nurse Based Motivational Interviewing (NBMI) on top of a routine patient based Lifestyle Inventory with Feedback (LIFE) in a cardiovascular outpatient secondary prevention setting.

METHODS

All current smokers (n=112), identified in 619 successive patients with cardiovascular disease, were randomized for either care as usual (LIFE), or LIFE plus NBMI (intervention group). Cumulative time investment was recorded.

RESULTS

After 3 months of follow-up, the abstinence rate in the control group was 7%, and another 15% diminished the number of cigarettes, whereas 26% of intervention patients quit smoking (p<0.017) and another 31% diminished smoking. On average, each completed motivational interviewing session took 63.5 min. Per quitter, time investment was 3.8 h and NNT appeared 5.9.

CONCLUSION

NBMI strategy on top of routinely administrated lifestyle self evaluation with professional feedback, significantly increases smoking cessation in an outpatient secondary prevention setting. Although cost effectiveness needs to be addressed, time investment per quitter in this approach appears low.
