Evaluation of a nurse-delivered smoking cessation intervention for hospitalized patients with cardiac disease

Feasibility of Nurse-Managed Tobacco Use Interventions in Outpatient Surgical Practice

PURPOSE

The aim of this study was to determine the feasibility of developing and implementing a brief nurse-delivered tobacco intervention in an outpatient surgical practice.

DESIGN AND METHODS

Initial formative work used a survey and focus groups to determine knowledge, attitudes, and practices of perioperative nurses working in three outpatient surgical practices regarding smoking use and cessation. Based on this work, a brief intervention was designed and implemented in one of the three practices. The documentation of tobacco use and intervention elements was assessed both immediately and approximately 9 months after implementation.

FINDINGS

Formative work identified not only several barriers to implementation and little current activity but also favorable attitudes toward interventions. Implementation improved self-efficacy for intervention delivery and compliance with documentation of intervention elements that was sustained for at least 9 months.

CONCLUSIONS

Our results suggest that it is feasible for perioperative nurses to play an important role in the delivery of perioperative tobacco interventions.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of telephone support to help smokers quit, including proactive or reactive counselling, or the provision of other information to smokers calling a helpline.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the ICTRP for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2018.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials which offered proactive or reactive telephone counselling to smokers to assist smoking cessation.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We pooled studies using a random-effects model and assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I² statistic. In trials including smokers who did not call a quitline, we used meta-regression to investigate moderation of the effect of telephone counselling by the planned number of calls in the intervention, trial selection of participants that were motivated to quit, and the baseline support provided together with telephone counselling (either self-help only, brief face-to-face intervention, pharmacotherapy, or financial incentives).

MAIN RESULTS

We identified 104 trials including 111,653 participants that met the inclusion criteria. Participants were mostly adult smokers from the general population, but some studies included teenagers, pregnant women, and people with long-term or mental health conditions. Most trials (58.7%) were at high risk of bias, while 30.8% were at unclear risk, and only 11.5% were at low risk of bias for all domains assessed. Most studies (100/104) assessed proactive telephone counselling, as opposed to reactive forms.Among trials including smokers who contacted helplines (32,484 participants), quit rates were higher for smokers receiving multiple sessions of proactive counselling (risk ratio (RR) 1.38, 95% confidence interval (CI) 1.19 to 1.61; 14 trials, 32,484 participants; I² = 72%) compared with a control condition providing self-help materials or brief counselling in a single call. Due to the substantial unexplained heterogeneity between studies, we downgraded the certainty of the evidence to moderate.In studies that recruited smokers who did not call a helpline, the provision of telephone counselling increased quit rates (RR 1.25, 95% CI 1.15 to 1.35; 65 trials, 41,233 participants; I² = 52%). Due to the substantial unexplained heterogeneity between studies, we downgraded the certainty of the evidence to moderate. In subgroup analysis, we found no evidence that the effect of telephone counselling depended upon whether or not other interventions were provided (P = 0.21), no evidence that more intensive support was more effective than less intensive (P = 0.43), or that the effect of telephone support depended upon whether or not people were actively trying to quit smoking (P = 0.32). However, in meta-regression, telephone counselling was associated with greater effectiveness when provided as an adjunct to self-help written support (P < 0.01), or to a brief intervention from a health professional (P = 0.02); telephone counselling was less effective when provided as an adjunct to more intensive counselling. Further, telephone support was more effective for people who were motivated to try to quit smoking (P = 0.02). The findings from three additional trials of smokers who had not proactively called a helpline but were offered telephone counselling, found quit rates were higher in those offered three to five telephone calls compared to those offered just one call (RR 1.27, 95% CI 1.12 to 1.44; 2602 participants; I² = 0%).

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that proactive telephone counselling aids smokers who seek help from quitlines, and moderate-certainty evidence that proactive telephone counselling increases quit rates in smokers in other settings. There is currently insufficient evidence to assess potential variations in effect from differences in the number of contacts, type or timing of telephone counselling, or when telephone counselling is provided as an adjunct to other smoking cessation therapies. Evidence was inconclusive on the effect of reactive telephone counselling, due to a limited number studies, which reflects the difficulty of studying this intervention.

Nursing interventions for smoking cessation

BACKGROUND

Healthcare professionals, including nurses, frequently advise people to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions.

OBJECTIVES

To determine the effectiveness of nursing-delivered smoking cessation interventions in adults. To establish whether nursing-delivered smoking cessation interventions are more effective than no intervention; are more effective if the intervention is more intensive; differ in effectiveness with health state and setting of the participants; are more effective if they include follow-ups; are more effective if they include aids that demonstrate the pathophysiological effect of smoking.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register and CINAHL in January 2017.

SELECTION CRITERIA

Randomized trials of smoking cessation interventions delivered by nurses or health visitors with follow-up of at least six months.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data independently. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically-validated rates if available. Where statistically and clinically appropriate, we pooled studies using a Mantel-Haenszel fixed-effect model and reported the outcome as a risk ratio (RR) with a 95% confidence interval (CI).

MAIN RESULTS

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.

AUTHORS' CONCLUSIONS

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.

Nursing interventions for smoking cessation in hospitalized patients: a systematic review

AIM

This study aimed to clarify the role of nurses in planning and implementation of nursing interventions related to smoking cessation.

BACKGROUND AND INTRODUCTION

Nearly half of all smokers die from smoking-related illnesses. Quitting smoking can reduce these problems. Smoking cessation interventions include various types helping smokers successfully quit. Studies suggest that hospitalization can be a golden opportunity for nurses helping patients to quit smoking because of No Smoking regulations.

METHOD

A systematic review of the literature was carried through Web of Knowledge, ProQuest, Medscape, MedlinePlus, Ovid SID, Magiran, PubMed, and Science Direct databases between 1990-2015 on the subject of interest by keywords: role of nursing in smoking cessation, nursing intervention in smoking cessation, smoking cessation, smoking quitting and interventions planned by nurse.

RESULT

Nineteen papers were systematic examined, dealing with smoking cessation interventions by nurses. Totally, 17 studies used counselling for quitting smoking. Most studies involved other methods such as manuals, pamphlets, brochures training or printed educational materials, audio and video file. Some studies used nicotine replacement methods for patients such as nicotine skin tags, chewing nicotine or bupropion. Moreover, 17 studies were conducted by telephone at patients' follow-up after hospital discharge.

CONCLUSION

Nurses' interventions for smoking cessation play an important role in helping patients quit smoking successfully. There are a variety of interventions that nurses can employ according to the patient's condition and diagnosis of different diseases.

IMPLICATION FOR NURSING AND HEALTH POLICY

Quitting smoking can reduce lung cancers and other health problems. Nurses play an important role in helping patients to quit smoking.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of proactive and reactive telephone support via helplines and in other settings to help smokers quit.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2013.

SELECTION CRITERIA

randomized or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters.

DATA COLLECTION AND ANALYSIS

One author identified and data extracted trials, and a second author checked them. The main outcome measure was the risk ratio for abstinence from smoking after at least six months follow-up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I² statistic. We considered trials recruiting callers to quitlines separately from studies recruiting in other settings. Where appropriate, we pooled studies using a fixed-effect model. We used a meta-regression to investigate the effect of differences in planned number of calls, selection for motivation, and the nature of the control condition (self help only, minimal intervention, pharmacotherapy) in the group of studies recruiting in non-quitline settings.

MAIN RESULTS

Seventy-seven trials met the inclusion criteria. Some trials were judged to be at risk of bias in some domains but overall we did not judge the results to be at high risk of bias. Among smokers who contacted helplines, quit rates were higher for groups randomized to receive multiple sessions of proactive counselling (nine studies, > 24,000 participants, risk ratio (RR) for cessation at longest follow-up 1.37, 95% confidence interval (CI) 1.26 to 1.50). There was mixed evidence about whether increasing the number of calls altered quit rates but most trials used more than two calls. Three studies comparing different counselling approaches during a single quitline contact did not detect significant differences. Of three studies that tested the provision of access to a hotline two detected a significant benefit and one did not.Telephone counselling not initiated by calls to helplines also increased quitting (51 studies, > 30,000 participants, RR 1.27; 95% CI 1.20 to 1.36). In a meta-regression controlling for other factors the effect was estimated to be slightly larger if more calls were offered, and in trials that specifically recruited smokers motivated to try to quit. The relative extra benefit of counselling was smaller when it was provided in addition to pharmacotherapy (usually nicotine replacement therapy) than when the control group only received self-help material or a brief intervention.A further eight studies were too diverse to contribute to meta-analyses and are discussed separately. Two compared different intensities of counselling, both of which detected a dose response; one of these detected a benefit of multiple counselling sessions over a single call for people prescribed bupropion. The others tested a variety of interventions largely involving offering telephone counselling as part of a referral or systems change and none detected evidence of effect.

AUTHORS' CONCLUSIONS

Proactive telephone counselling aids smokers who seek help from quitlines. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness. There is limited evidence about the optimal number of calls. Proactive telephone counselling also helps people who receive it in other settings. There is some evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increase the chances of quitting compared to a minimal intervention such as providing standard self-help materials, or brief advice, or compared to pharmacotherapy alone.

Nursing interventions for smoking cessation

BACKGROUND

Healthcare professionals, including nurses, frequently advise people to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions.

OBJECTIVES

To determine the effectiveness of nursing-delivered smoking cessation interventions.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group specialized Register and CINAHL in June 2013.

SELECTION CRITERIA

Randomized trials of smoking cessation interventions delivered by nurses or health visitors with follow-up of at least six months.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Where statistically and clinically appropriate, we pooled studies using a Mantel-Haenszel fixed-effect model and reported the outcome as a risk ratio (RR) with a 95% confidence interval (CI).

MAIN RESULTS

Forty-nine studies met the inclusion criteria. Pooling 35 studies (over 17,000 participants) comparing a nursing intervention to a control or to usual care, we found the intervention to increase the likelihood of quitting (RR 1.29; 95% CI 1.20 to 1.39). In a subgroup analysis the estimated effect size was similar for the group of seven studies using a particularly low intensity intervention but the confidence interval was wider. There was limited indirect evidence that interventions were more effective for hospital inpatients with cardiovascular disease than for inpatients with other conditions. Interventions in non-hospitalized adults also showed evidence of benefit. Eleven studies comparing different nurse-delivered interventions failed to detect significant benefit from using additional components. Six studies of nurse counselling on smoking cessation during a screening health check or as part of multifactorial secondary prevention in general practice (not included in the main meta-analysis) found nursing intervention to have less effect under these conditions.

AUTHORS' CONCLUSIONS

The results indicate the potential benefits of smoking cessation advice and/or counselling given by nurses, with reasonable evidence that intervention is effective. The evidence for an effect is weaker when interventions are brief and are provided by nurses whose main role is not health promotion or smoking cessation. The challenge will be to incorporate smoking behaviour monitoring and smoking cessation interventions as part of standard practice so that all patients are given an opportunity to be asked about their tobacco use and to be given advice and/or counselling to quit along with reinforcement and follow-up.

Interventions for smoking cessation in hospitalised patients

BACKGROUND

Smoking contributes to reasons for hospitalisation, and the period of hospitalisation may be a good time to provide help with quitting.

OBJECTIVES

To determine the effectiveness of interventions for smoking cessation that are initiated for hospitalised patients.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group register which includes papers identified from CENTRAL, MEDLINE, EMBASE and PsycINFO in December 2011 for studies of interventions for smoking cessation in hospitalised patients, using terms including (hospital and patient*) or hospitali* or inpatient* or admission* or admitted.

SELECTION CRITERIA

Randomized and quasi-randomized trials of behavioural, pharmacological or multicomponent interventions to help patients stop smoking, conducted with hospitalised patients who were current smokers or recent quitters (defined as having quit more than one month before hospital admission). The intervention had to start in the hospital but could continue after hospital discharge. We excluded studies of patients admitted to facilities that primarily treat psychiatric disorders or substance abuse, studies that did not report abstinence rates and studies with follow-up of less than six months. Both acute care hospitals and rehabilitation hospitals were included in this update, with separate analyses done for each type of hospital.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently for each paper, with disagreements resolved by consensus.

MAIN RESULTS

Fifty trials met the inclusion criteria. Intensive counselling interventions that began during the hospital stay and continued with supportive contacts for at least one month after discharge increased smoking cessation rates after discharge (risk ratio (RR) 1.37, 95% confidence interval (CI) 1.27 to 1.48; 25 trials). A specific benefit for post-discharge contact compared with usual care was found in a subset of trials in which all participants received a counselling intervention in the hospital and were randomly assigned to post-discharge contact or usual care. No statistically significant benefit was found for less intensive counselling interventions. Adding nicotine replacement therapy (NRT) to an intensive counselling intervention increased smoking cessation rates compared with intensive counselling alone (RR 1.54, 95% CI 1.34 to 1.79, six trials). Adding varenicline to intensive counselling had a non-significant effect in two trials (RR 1.28, 95% CI 0.95 to 1.74). Adding bupropion did not produce a statistically significant increase in cessation over intensive counselling alone (RR 1.04, 95% CI 0.75 to 1.45, three trials). A similar pattern of results was observed in a subgroup of smokers admitted to hospital because of cardiovascular disease (CVD). In this subgroup, intensive intervention with follow-up support increased the rate of smoking cessation (RR 1.42, 95% CI 1.29 to 1.56), but less intensive interventions did not. One trial of intensive intervention including counselling and pharmacotherapy for smokers admitted with CVD assessed clinical and health care utilization endpoints, and found significant reductions in all-cause mortality and hospital readmission rates over a two-year follow-up period. These trials were all conducted in acute care hospitals. A comparable increase in smoking cessation rates was observed in a separate pooled analysis of intensive counselling interventions in rehabilitation hospitals (RR 1.71, 95% CI 1.37 to 2.14, three trials).

AUTHORS' CONCLUSIONS

High intensity behavioural interventions that begin during a hospital stay and include at least one month of supportive contact after discharge promote smoking cessation among hospitalised patients. The effect of these interventions was independent of the patient's admitting diagnosis and was found in rehabilitation settings as well as acute care hospitals. There was no evidence of effect for interventions of lower intensity or shorter duration. This update found that adding NRT to intensive counselling significantly increases cessation rates over counselling alone. There is insufficient direct evidence to conclude that adding bupropion or varenicline to intensive counselling increases cessation rates over what is achieved by counselling alone.

Effects of a Brief Cognitive Intervention Aimed at Communicating the Negative Reinforcement Explanation for Smoking on Relevant Cognitions and Urges to Smoke

Introduction:The aim of the current study was to assess the impact of an intervention aimed at communicating the negative reinforcement explanation for smoking, a set of ideas derived from popular self-help books, upon participants' cognitions and urges to smoke. Methods: Smokers (n = 205) undergoing standard stop-smoking treatment were randomised to receive either the experimental intervention, a brief intervention aimed at communicating the explanation or a control intervention, a video on the health risks of smoking. Outcomes were participants' acceptance of the negative reinforcement explanation for smoking, positive outcome expectations for smoking, self-efficacy and urges to smoke reported at one week post-cessation. Results: Post-cessation urges to smoke were similar in the two groups (Adjusted expt. group mean = 2.50, Control group mean = 2.75, F(1,60) = 0.98, p = .33). Other cognitive measures were also unchanged. Conclusions: The brief cognitive intervention offered as an adjunct to standard care failed to reduce urges to smoke or alter smokers' cognitions. Changing smokers' cognitions may be as challenging as changing their behaviours. Suggestions are provided for further research.

Nurse-led telephone interventions for people with cardiac disease: a review of the research literature

BACKGROUND

Nurse-led telephone follow-up offers a relatively inexpensive method of delivering education and support for assisting recovery in the early discharge period; however, its efficacy is yet to be determined.

AIM

To perform a critical integrative review of the research literature addressing the effectiveness of nurse-led telephone interventions for people with coronary heart disease (CHD).

METHODS

A literature search of five health care databases; Sciencedirect, Cumulative Index to Nursing and Allied Health Literature, Pubmed, Proquest and Medline to identify journal articles between 1980 and 2009. People with cardiac disease were considered for inclusion in this review. The search yielded 128 papers, of which 24 met the inclusion criteria.

RESULTS

A total of 8330 participants from 24 studies were included in the final review. Seven studies demonstrated statistically significant differences in all outcomes measured, used two group experimental research design and valid and reliable instruments. Some positive effects were detected in eight studies in regards to nurse-led telephone interventions for people with cardiac disease and no differences were detected in nine studies.

DISCUSSION

Studies with some positive effects generally had stronger research designs, large samples, used valid and reliable instruments and extensive nurse-led educative interventions.

CONCLUSION

The results suggest that people with cardiac disease showed some benefits from nurse-led/delivered telephone interventions. More rigorous research into this area is needed.

The efficacy of smoking cessation therapies in cardiac patients: a meta-analysis of randomized controlled trials

INTRODUCTION

Several meta-analyses have examined the efficacy of smoking cessation therapies in the general population. However, little is known about the efficacy of these therapies in cardiac patients. Therefore, a meta-analysis of randomized controlled trials (RCTs) was performed to determine the efficacy of behavioural therapy and pharmacotherapy for smoking cessation in cardiac patients.

METHODS

The medical literature was systematically reviewed to identify smoking cessation RCTs in cardiac patients. Only RCTs that reported smoking abstinence at six or 12 months were included. Smoking abstinence was examined based on the 'most rigorous criterion', defined as the most conservative outcome reported in any given RCT.

RESULTS

Eleven behavioural therapy RCTs that enrolled 2105 patients and four pharmacotherapy RCTs that enrolled 1542 patients were identified. RCTs differed in the type of behavioural therapy administered as well as the total length and duration of the intervention. RCTs differed in the type of pharmacotherapy administered (one nicotine patch RCT, one nicotine gum RCT and two bupropion RCTs). Behavioural therapy was associated with a significantly higher proportion of smoking abstinence than usual care (OR 1.97 [95% CI 1.37 to 2.85]). Pharmacotherapies were more efficacious than placebo (pooled OR 1.72 [95% CI 1.15 to 2.57]).

CONCLUSIONS

Both behavioural therapy and pharmacotherapy are more efficacious than usual care for smoking cessation in cardiac patients. The present meta-analysis highlights the need for head-to-head RCTs to identify which smoking cessation therapy is preferred in cardiac patients as well as RCTs examining the efficacy of combined behavioural and pharmacotherapies.

Are psychoeducational smoking cessation interventions for coronary heart disease patients effective? Meta-analysis of interventions

PURPOSE

This systematic review aimed to assess the effectiveness of psychoeducational smoking cessation interventions for coronary heart disease (CHD) patients; and to examine behaviour change techniques used in interventions and their suitability to change behavioural determinants.

METHODS

Multiple bibliographic databases and references of retrieved articles were searched for relevant randomized controlled studies. One reviewer extracted and a second reviewer checked data from included trials. Random effects meta-analyses were conducted to estimate pooled relative risks for smoking cessation and mortality outcomes. Behaviour change techniques used and their suitability to change behavioural determinants were evaluated using a framework by Michie, Johnston, Francis, Hardeman, and Eccles.

RESULTS

A total of 14 studies were included. Psychoeducational interventions statistically significantly increased point prevalent (RR 1.44, 95% CI, 1.20-1.73) and continuous (RR 1.51, 95% CI, 1.18-1.93) smoking cessation, and statistically non-significantly decreased total mortality (RR 0.73, 95% CI, 0.46-1.15). Included studies used a mixture of theories in intervention planning. Despite superficial differences, interventions appear to deploy similar behaviour change techniques, targeted mainly at motivation and goals, beliefs about capacity, knowledge, and skills.

CONCLUSIONS

Psychoeducational smoking cessation interventions appear effective for patients with CHD. Although questions remain about what characteristics distinguish an effective intervention, analysis indicates similarities between the behaviour change techniques used in such interventions.

Effect of preoperative smoking cessation interventions on postoperative complications and smoking cessation

Background

The aim of this study was to examine the effect of preoperative smoking cessation interventions on postoperative complications and smoking cessation itself.

Methods

Relevant databases were searched for randomized controlled trials (RCTs) of preoperative smoking cessation interventions. Trial inclusion, risk of bias assessment and data extraction were performed by two authors. Risk ratios for the above outcomes were calculated and pooled effects estimated using the fixed-effect method.

Results

Eleven RCTs were included containing 1194 patients. Smoking interventions were intensive, medium intensity and less intensive. Follow-up for postoperative complications was 30 days. For smoking cessation it was from the day of surgery to 12 months thereafter. Overall, the interventions significantly reduced the occurrence of complications (pooled risk ratio 0·56 (95 per cent confidence interval 0·41 to 0·78); P &lt; 0·001). Intensive interventions increased smoking cessation rates both before operation and up to 12 months thereafter. The effects of medium to less intensive interventions were not significant. Meta-analysis of the effect on smoking cessation was not done owing to heterogeneity of data.

Conclusion

Surgical patients may benefit from intensive preoperative smoking cessation interventions. These include individual counselling initiated at least 4 weeks before operation and nicotine replacement therapy.

Predictors of smoking relapse in women with cardiovascular disease in a 30-month study: extended analysis

PURPOSE

To identify predictors of long-term cessation after intervention for woman hospitalized with cardiovascular diseases (CVD).

METHODS

A randomized clinical trial (RCT) with a 30-month follow-up was conducted, recruiting 277 woman smokers with CVD from 10 hospitals. The intervention consisted of inpatient and outpatient counseling on smoking cessation and pharmacological protocol. Psychophysiological factors and time since quitting associated with relapse in the literature were assessed in our prediction model.

RESULTS

The nine independent variables for smoking relapse included time since quitting, group assignment, the interaction between time and group assignment, serious quit attempts and five and psychophysiological factors. Lower self-efficacy at baseline was a significant predictor of relapse (OR = 0.98, 95%CI = 0.97,0.99). Another predictor was the interaction between time and group assignment and the finding showed that for the usual care group, increase in time since quitting provided a significant protective factor (OR = 0.69, 95%CI = 0.60,0.79).

CONCLUSIONS

Cessation programs should include content on self-efficacy to help prevent relapse. The interaction between time and group warrants further investigation for its prediction for relapse.

Interventions to increase self-efficacy in the context of addiction behaviours: a systematic literature review

This article describes the effectiveness of interventions aimed at increasing self-efficacy and consequently, changing addiction behaviours. Electronic databases were searched and bibliographies of retrieved references scanned. Ten studies targeting tobacco smoking, alcohol and illicit drug use met the inclusion criteria. The interventions ranged from computer-generated tailored letters to intensive group-based interventions. Seven of the 10 studies reported positive effects of interventions upon self-efficacy. The two that assessed behaviour change reported a significant effect but as neither performed mediation analyses, behaviour change could not reliably be attributed to self-efficacy change. In conclusion, self-efficacy can be increased using a range of methods. There is, however, little evidence to determine whether such increases change behaviour.

Factors associated with smoking cessation among male adults with coronary heart disease in Taiwan

The purpose of this study was to examine factors associated with smoking cessation behavior among male adult smokers hospitalized for a cardiac event in Taiwan during the three-month period following their discharge from hospital. A longitudinal correlational design using two structured questionnaires and two phone interviews was employed to collect data. A convenient sampling was adopted. Among the 250 potential participants recruited, 148 provided completed data and were included as study subjects. Three months after hospital discharge, 43.9% of subjects were defined as "continuous abstainers" (i.e., not a single cigarette puff taken during this period), 33.8% were "non-continuous abstainers" (i.e., abstained for at least 1 day, but had smoked at some point during this period), and 22.3% were "continuous smokers" (i.e., had not abstained from smoking for any period equal to or exceeding 24 hours during this period). Multivariate analysis (hierarchical logistic regression) revealed that subjects with higher self-efficacy in not smoking and greater perceived positive family support were more likely to quit smoking for at least 24 hours (i.e., "attempters"). Attempters who stayed in hospital for longer periods of time, had higher self-efficacy in not smoking or perceived more positive and fewer negative family support behaviors were more likely to become continuous abstainers. These results suggest that self-efficacy and family support should be addressed in any intervention program targeting smoking cessation in male patients with coronary heart disease.

Nursing interventions for smoking cessation

BACKGROUND

Healthcare professionals, including nurses, frequently advise patients to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions.

OBJECTIVES

To determine the effectiveness of nursing-delivered smoking cessation interventions.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group specialized register and CINAHL in July 2007.

SELECTION CRITERIA

Randomized trials of smoking cessation interventions delivered by nurses or health visitors with follow up of at least six months.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently. The main outcome measure was abstinence from smoking after at least six months of follow up. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Where statistically and clinically appropriate, we pooled studies using a Mantel-Haenszel fixed effect model and reported the outcome as a risk ratio (RR) with 95% confidence interval (CI).

MAIN RESULTS

Forty-two studies met the inclusion criteria. Thirty-one studies comparing a nursing intervention to a control or to usual care found the intervention to significantly increase the likelihood of quitting (RR 1.28, 95% CI 1.18 to 1.38). There was heterogeneity among the study results, but pooling using a random effects model did not alter the estimate of a statistically significant effect. In a subgroup analysis there was weaker evidence that lower intensity interventions were effective (RR 1.27, 95% CI 0.99 to 1.62). There was limited indirect evidence that interventions were more effective for hospital inpatients with cardiovascular disease than for inpatients with other conditions. Interventions in non-hospitalized patients also showed evidence of benefit. Nine studies comparing different nurse-delivered interventions failed to detect significant benefit from using additional components. Five studies of nurse counselling on smoking cessation during a screening health check, or as part of multifactorial secondary prevention in general practice (not included in the main meta-analysis) found nursing intervention to have less effect under these conditions.

AUTHORS' CONCLUSIONS

The results indicate the potential benefits of smoking cessation advice and/or counselling given by nurses to patients, with reasonable evidence that intervention is effective. The evidence of an effect is weaker when interventions are brief and are provided by nurses whose main role is not health promotion or smoking cessation. The challenge will be to incorporate smoking behaviour monitoring and smoking cessation interventions as part of standard practice, so that all patients are given an opportunity to be asked about their tobacco use and to be given advice and/or counselling to quit along with reinforcement and follow up.

Effect of an Inpatient Nurse-Directed Smoking Cessation Program

The purpose of this study was to evaluate the effect of a nurse-directed smoking cessation intervention for adults hospitalized in a small community hospital using a quasiexperimental, prospective, longitudinal design with biochemical validation of self-reported tobacco abstinence. Sixty-eight inpatients were assigned to either a control ( n = 30) or an intervention group ( n = 38). The control group received smoking cessation literature. The intervention group received smoking cessation literature and a nursing intervention. Each member of the intervention group was randomly assigned to a one or four telephone call subgroup for post discharge nurse follow-up at 3 months. Fifty-five participants completed the study. Smokers receiving the nurse-directed intervention were significantly more likely to be tobacco abstinent at 3 months ( n = 17, 55%) than smokers in the control group ( n = 5, 21%). Within the intervention group, tobacco abstinence at 3 months was not significantly different between the one and four telephone call groups. For the total sample, smoking relapse was significantly higher for participants who lived with another smoker.

Interventions for smoking cessation in hospitalised patients

BACKGROUND

An admission to hospital provides an opportunity to help people stop smoking. Individuals may be more open to help at a time of perceived vulnerability, and may find it easier to quit in an environment where smoking is restricted or prohibited. Initiating smoking cessation services during hospitalisation may help more people to make and sustain a quit attempt.

OBJECTIVES

To determine the effectiveness of interventions for smoking cessation that are initiated for hospitalised patients.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group register which includes papers identified from CENTRAL, MEDLINE, EMBASE and PSYCINFO in January 2007, and CINAHL in August 2006 for studies of interventions for smoking cessation in hospitalised patients, using terms including (hospital and patient*) or hospitali* or inpatient* or admission* or admitted.

SELECTION CRITERIA

Randomized and quasi-randomized trials of behavioural, pharmacological or multicomponent interventions to help patients stop smoking, conducted with hospitalised patients who were current smokers or recent quitters (defined as having quit more than one month before hospital admission). The intervention had to start in the hospital but could continue after hospital discharge. We excluded studies of patients admitted for psychiatric disorders or substance abuse, studies that did not report abstinence rates and studies with follow up of less than six months.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently for each paper, with disagreements resolved by consensus.

MAIN RESULTS

Thirty-three trials met the inclusion criteria. Intensive counselling interventions that began during the hospital stay and continued with supportive contacts for at least one month after discharge increased smoking cessation rates after discharge (Odds Ratio (OR) 1.65, 95% confidence interval (CI) 1.44 to 1.90; 17 trials). No statistically significant benefit was found for less intensive counselling interventions. The one study that tested a single brief (<=15 minutes) in-hospital intervention did not find it to be effective (OR 1.16, 95% CI 0.80 to 1.67). Counselling of longer duration during the hospital stay was not associated with a higher quit rate (OR 1.08, 95% CI 0.89 to 1.29, eight trials). Even counselling that began in the hospital but had less than one month of supportive contact after discharge did not show significant benefit (OR 1.09, 95% CI 0.91 to 1.31, six trials). Adding nicotine replacement therapy (NRT) did not produce a statistically significant increase in cessation over what was achieved by intensive counselling alone (OR 1.47, 95% CI 0.92 to 2.35, five studies). The one study that tested the effect of adding bupropion to intensive counselling had a similar nonsignificant effect (OR 1.56, 95% CI 0.79 to 3.06). A similar pattern of results was observed in smokers admitted to hospital because of cardiovascular disease (CVD). In this subgroup, intensive intervention with follow-up support increased the odds of smoking cessation (OR 1.81, 95% CI 1.54 to 2.15, 11 trials), but less intensive interventions did not. One trial of intensive intervention including counselling and pharmacotherapy for smokers admitted with CVD assessed clinical and health care utilization endpoints, and found significant reductions in all-cause mortality and hospital readmission rates over a two-year follow-up period.

AUTHORS' CONCLUSIONS

High intensity behavioural interventions that begin during a hospital stay and include at least one month of supportive contact after discharge promote smoking cessation among hospitalised patients. These interventions are effective regardless of the patient's admitting diagnosis. lnterventions of lower intensity or shorter duration have not been shown to be effective in this setting. There is insufficient direct evidence to conclude that adding NRT or bupropion to intensive counselling increases cessation rates over what is achieved by counselling alone, but the evidence of benefit for NRT has strengthened in this update and the point estimates are compatible with research in other settings showing that NRT and bupropion are effective.

Intensive Smoking Cessation Intervention Reduces Mortality in High-Risk Smokers With Cardiovascular Disease

PURPOSES

To compare an intensive smoking cessation intervention against usual care in hospitalized high-risk smokers with acute cardiovascular disease.

METHODS

A total of 209 hospitalized smokers were randomized to the intensive intervention (n = 109) or to usual care (n = 100). Usual care consisted only of counseling and printed educational material provided prior to hospital discharge. Intensive treatment consisted of a minimum of 12 weeks of behavior modification counseling and individualized pharmacotherapy provided at no cost to the participant. Smoking status in all subjects was confirmed biochemically (ie, by measuring expired carbon monoxide) at 3, 6, 12, and 24 months after randomization. Outcomes included point prevalence and continuous abstinence smoking cessation rates, hospitalizations, and all-cause mortality.

RESULTS

At each follow-up interval, point prevalence and continuous abstinence smoking cessation rates were significantly greater in the intensive-treatment group compared to the usual-care group. At 24 months, continuous abstinence smoking cessation rates were 33% in the intensive-treatment group and 9% in the usual-care group (p < 0.0001). Over the 2-year follow-up period, 41 patients in the usual-care group were hospitalized compared to 25 patients in the intensive-treatment group (relative risk reduction [RRR], 44%; 95% confidence interval [CI], 16 to 63%; p = 0.007). The all-cause mortality rate was 2.8% in the intensive-treatment group and 12.0% in the usual-care group (RRR, 77%; 95% CI, 27 to 93%; p = 0.014). The absolute risk reduction in mortality was 9.2% with a number needed to treat of 11.

CONCLUSION

Hospitalized smokers, especially those with cardiovascular disease, should undergo treatment with a structured intensive cessation intervention. The duration of the initial treatment should be 3 months.

Nurses' opportunistic interventions with patients in relation to smoking

AIM

This paper reports a study exploring nurses' provision of opportunistic health education on smoking for hospital patients.

BACKGROUND

Smoking cessation guidelines recommend assessment of patients' smoking habits and provision of smoking cessation advice when possible, and highlight the importance of the role of nurses in health promotion and health education. In the past, nurses have been criticized for lack of knowledge, skills and confidence in relation to health education and the perception that it is additional to, rather than integrated with, nursing care.

METHODS

A qualitative case study design was selected to explore the health education practice of 12 nurses working in acute wards in three general hospitals in Scotland. Data were collected in 2000 through non-participant observation, semi-structured interviews and the use of a radio-microphone to record nurse-patient interactions. The data analysis was guided by four key elements of health education practice: 'the teachable moment', 'readiness to learn', 'the provision of health information' and 'oral communication'.

FINDINGS

Smoking was part of the nurses' agenda, as most recognized opportunities to introduce health education on smoking during nursing care, suggesting a tentative move towards the integration of health education with nursing care. Evidence from patients' interactions indicated ample opportunity for nurses to provide smoking-related health information. However, the content of nurses' interactions on smoking was variable, with some limited by poor communication skills and inadequate knowledge of smoking and smoking cessation. The context of the interactions was also important in understanding some of the restrictions on conversational progress.

CONCLUSIONS

Nurses require the knowledge and skills to perform a health education role, and the inclusion of smoking cessation guidelines in nursing curricula would contribute to this. Where patients are in hospitals for short periods of time, opportunistic health education on smoking needs to be introduced as the basis for more specialist intervention.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of proactive and reactive telephone support to help smokers quit.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group trials register for studies using free text term 'telephone*' or the keywords 'telephone counselling' or 'Hotlines' or 'Telephone' . Date of the most recent search: January 2006.

SELECTION CRITERIA

Randomized or quasi-randomized controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters.

DATA COLLECTION AND ANALYSIS

Trials were identified and data extracted by one person (LS) and checked by a second (TL). The main outcome measure was the odds ratio for abstinence from smoking after at least six months follow up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst sub groups of clinically comparable studies using the I(2) statistic. Where appropriate, we pooled studies using a fixed-effect model. A meta-regression was used to investigate the effect of differences in planned number of calls.

MAIN RESULTS

Forty-eight trials met the inclusion criteria. Among smokers who contacted helplines, quit rates were higher for groups randomised to receive multiple sessions of call-back counselling (eight studies, >18,000 participants, odds ratio (OR) for long term cessation 1.41, 95% confidence interval (CI) 1.27 to 1.57). Two of these studies showed a significant benefit of more intensive compared to less intensive intervention. Telephone counselling not initiated by calls to helplines also increased quitting (29 studies, >17,000 participants, OR 1.33, 95% CI 1.21 to 1.47). A meta-regression detected a significant association between the maximum number of planned calls and the effect size. There was clearer evidence of benefit in the subgroup of trials recruiting smokers motivated to quit. Of two studies that provided access to a hotline one showed a significant benefit and one did not. Two studies comparing different counselling approaches during a single session did not detect significant differences. A further seven studies were too diverse to contribute to meta-analyses and are discussed separately.

AUTHORS' CONCLUSIONS

Proactive telephone counselling helps smokers interested in quitting. There is evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increases the odds of quitting compared to a minimal intervention such as providing standard self-help materials, brief advice, or compared to pharmacotherapy alone. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness.

[Feasibility of systematic screening for addictive behaviours of hospitalized patients]

BACKGROUND

The national policy against addiction led to the establishment of specialized units with liaison teams trained in addiction specifically to work with the in-patients. The aim of this study has been established within the context of the implementation of one of these addiction liaison units in a Parisian Hospital, the Georges Pompidou European Hospital (HEGP), that is namely to evaluate the feasibility of a systematic screening procedure concerning tobacco and alcohol dependence among inpatients in two of the hospital's specialization departments between December 6, 2001, and March 6, 2002.

METHODS

Self-administered questionnaires on addictive behaviours were distributed to each patient admitted to the vascular health department and to the hypertension department They included the Fagerström Test for Nicotine Dependence and the AUDIT for evaluating levels of alcohol abuse.

RESULTS

The response rate was 30.2% (110/364). Twenty-nine smokers were identified. Among them, 72.5% presented a low level of physical nicotine dependence. Nearly half of them (14/29) were not interested in participating in a smoking cessation intervention with the assistance of relevant hospital staff. Among eleven patients at risk of excessive alcohol abuse, only one accepted to be referred to a specialist.

CONCLUSION

This study highlights the difficulties of the systematic screening for addictive behaviours in hospitalized patients. Nevertheless, the obstacles faced in terms of the acceptability of the screening, but the patients as well as by the hospital staff, do not lean against the development of this trend or oppose this type of approach. New methods of individual screening for addictive behaviours should be explored.

The effectiveness of a nursing inpatient smoking cessation program in individuals with cardiovascular disease

BACKGROUND

Smoking is an important risk factor for cardiovascular disease (CVD), and quitting is highly beneficial. Yet, less than 30% of CVD patients stop smoking. Relapse-prevention strategies seem most effective when initiated during the exacerbation of the disease.

OBJECTIVE

A nurse-delivered inpatient smoking cessation program based on the Transtheoretical Model with telephone follow-up tailored to levels of readiness to quit smoking was evaluated on smoking abstinence and progress to ulterior stages of change.

METHOD

Participants (N = 168) were randomly assigned by cohorts to inpatient counseling with telephone follow-up, inpatient counseling, and usual care. The inpatient intervention consisted of a 1-hr counseling session, and the telephone follow-up included 6 calls during the first 2 months after discharge. The nursing intervention was tailored to the individual's stage of change. End points at 2 and 6 months included actual and continuous smoking cessation rates (biochemical markers) and increased motivation (progress to ulterior stages of change).

RESULTS

Assuming that surviving patients lost to follow-up were smokers, the 6-month smoking abstinence rate was 41.5% in the inpatient counseling with telephone follow-up group, compared with 30.2% and 20% in the inpatient counseling and usual care groups, respectively (p = .05). Progress to ulterior stages of change was 43.3%, 32.1%, and 18.2%, respectively (p = .02). Stage of change at baseline and intervention predicted smoking status at 6 months.

DISCUSSION

This tailored smoking cessation program with telephone follow-up significantly increased smoking cessation at 6 months, and progression to ulterior stages of change. The telephone follow-up was an important adjunct. It is, therefore, recommended to include such comprehensive smoking cessation programs within hospital settings for individuals with CVD.

The Effects of a Theory-Based Training Program on Nurses' Self-Efficacy and Behavior for Smoking Cessation Counseling

BACKGROUND

Cigarette smoking continues to put Americans at risk for serious health consequences and early death. Nurses play an important role in disseminating smoking cessation interventions to patients in the hospital. However, nurses are not prepared for smoking cessation counseling.

METHOD

A quasi-experimental design was used. Fifteen nurses participated in the Clinical Practice Guideline "5 A's" brief intervention training program, completing a survey during three time periods.

RESULTS

There were several statistically significant changes in the dependent variables for self-efficacy and behavior for smoking cessation counseling.

CONCLUSION

Results of this study support further research and theory-based training for nurses.

Smoking abstinence after hospitalization: predictors of success

BACKGROUND

Our objective was to explore the relationship between baseline characteristics of hospitalized smokers and 6-month to 2-year self-reported quit rates.

METHODS

We surveyed adult smokers (n = 154) admitted to the Medicine service of an urban public hospital. We used the pharmacy database, a follow-up telephone survey, and medical records to characterize nicotine patch use and post-discharge smoking abstinence.

RESULTS

Among the 102 patients for whom smoking status at least 6 months after discharge was known, 18 (18%) were not smoking at last contact (mean follow-up 20 months). Individual factors associated with quitting include confidence to quit within 1 week, stage of change other than precontemplation, filling a nicotine patch prescription after discharge, number of previous quit attempts, and increasing age. With multivariate modeling, only confidence to quit [OR 9.8, confidence interval (CI), 2.8-35.0] and the number of previous quit attempts (OR 1.3 per attempt, 95% CI, 1.0-1.5) remained significantly associated with future abstinence.

CONCLUSIONS

A high level of confidence to quit and multiple prior quit attempts are strongly associated with future abstinence among hospitalized patients who smoke. Using a simple confidence-to-quit scale to target interventions to patients with high confidence may improve the effectiveness of smoking cessation programs.

Survey of Tobacco Cessation Curricula in Kansas Nursing Programs

Tobacco use is a major health risk that requires a comprehensive response by healthcare professionals. Nurse educators can contribute to the reduction of tobacco use by educating nursing students about tobacco use and smoking cessation strategies. The authors examine the breadth and depth of tobacco cessation content in Kansas registered nursing programs providing insight into the content and resources needed to teach nursing faculty and students how to assist individuals in tobacco use cessation.

Nursing Outcomes in Coronary Heart Disease

Nursing research has contributed to our knowledge of patients with coronary heart disease (CHD), although much of the research has focused on acute cardiac events. Active and ongoing programs of research into CHD patient outcomes are essential as significant gaps remain. Consistently effective strategies to help patients change risk behaviors, recognize salient symptoms, manage their CHD and ischemic symptoms, improve function and quality of life, and prevent subsequent coronary events are needed, especially in the elderly and those with multiple comorbidities.

Smoking habits and predictors of continued smoking in patients with acute coronary syndromes

BACKGROUND

Most patients with acute coronary syndrome quit smoking when hospitalized, although several have been found to relapse and resume smoking within 3 months.

AIM

This paper reports a study to identify factors that can predict who will resume smoking after hospitalization for an acute coronary syndrome.

METHODS

Patients (n = 1320) below the age of 75 years, admitted to a Swedish university hospital coronary care unit with acute coronary syndromes, between September 1995 and September 1999, were consecutively included. Data were collected from hospital medical records and included information on previous clinical history, former illnesses and smoking. During their hospitalization, an experienced nurse interviewed the patients by using a structured questionnaire to obtain additional information. Patients were followed up 3 months after the discharge. Those who continued to smoke (non-quitters) were compared with those who had stopped (quitters) with regard to age, sex, medical history, clinical course, and intention to quit. To identify factors independently related to continued smoking, a logistical regression in a formal forward stepwise mode was used.

RESULTS

Of the patients admitted, 33% were current smokers. Three months after discharge, 51% of these patients were still smoking. There were no significant differences in age, gender or marital status between non-quitters and quitters. In a multivariate analysis, independent predictors of continued smoking were: non-participation in the heart rehabilitation programme (P = 0.0008); use of sedatives/antidepressants at time of admission (P = 0.001); history of cerebral vascular disease (P = 0.002), history of previous cardiac event (P = 0.01); history of smoking-related pulmonary disease (P = 0.03) and cigarette consumption at index (P = 0.03).

CONCLUSIONS

Smoking patients who do not participate in a heart rehabilitation programme may need extra help with smoking cessation. The findings may provide means of identifying patients in need of special intervention.

Efficacy of a smoking-cessation intervention for elective-surgical patients

We tested an intervention to help smokers abstain (fast) from smoking before surgery, maintain abstinence postoperatively, and achieve long-term cessation. A randomized experiment included 237 patients admitted for presurgical assessment who smoked. The intervention included counseling and nicotine replacement therapy. Treatment group participants (73.0%) were more likely to fast than were controls (53.0%): chi(2)(1, N = 228) = 8.89, p =.003, and more likely to be abstinent 6 months after surgery (31.2% vs. 20.2%). There was no significant difference in the abstinence rates at 12 months after surgery, chi(2)(1, N = 169) <.001, p = 1.00. Encouraging patients to fast from smoking before surgery and postoperative support are efficacious ways to reduce preoperative and immediate post-operative tobacco use.

Intervention, intervene, interfere ... what are we doing?

TOPIC

A concept analysis of the meaning and attributes of the term intervention.

PURPOSE

To define the essence of the term intervention and the role of nurses in nurse-facilitated interventions.

SOURCES

Literature review of journals, texts, and popular periodicals from 1983 to the present via CINAHL and Medline.

CONCLUSIONS

A more accurate specification of the meaning and relevant attributes of the term intervention as it relates to nursing may lead to more effective clinical applications, as well as a more realistic definition of the term intervention and how it applies to the role.

Nursing interventions for smoking cessation

BACKGROUND

Health care professionals, including nurses, frequently advise patients to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions.

OBJECTIVES

To determine the effectiveness of nursing-delivered smoking cessation interventions.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group specialized register and CINAHL in June 2003.

SELECTION CRITERIA

Randomized trials of smoking cessation interventions delivered by nurses or health visitors with follow-up of at least six months.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently.

MAIN RESULTS

Twenty-nine studies met the inclusion criteria. Twenty studies comparing a nursing intervention to a control or to usual care found the intervention to significantly increase the odds of quitting (Peto Odds Ratio 1.47, 95% CI 1.29 to 1.68). There was heterogeneity among the study results, but pooling using a random effects model did not alter the estimate of a statistically significant effect. There was limited evidence that interventions were more effective for hospital inpatients with cardiovascular disease than for inpatients with other conditions. Interventions in non-hospitalized patients also showed evidence of benefit. Five studies comparing different nurse-delivered interventions failed to detect significant benefit from using additional components. Five studies of nurse counselling on smoking cessation during a screening health check, or as part of multifactorial secondary prevention in general practice (not included in the main meta-analysis) found the nursing intervention to have less effect under these conditions.

REVIEWER'S CONCLUSIONS

The results indicate the potential benefits of smoking cessation advice and/or counselling given by nurses to patients, with reasonable evidence that interventions can be effective. The challenge will be to incorporate smoking behaviour monitoring and smoking cessation interventions as part of standard practice, so that all patients are given an opportunity to be asked about their tobacco use and to be given advice and/or counselling to quit along with reinforcement and follow-up.

Nursing and tobacco reduction: a review of the literature

Nurses have an instrumental role to play in tobacco reduction, which is one strategy used to address tobacco use; a primary source of preventable morbidity and mortality globally. The following review addresses activities by two groups of nurses: nursing governance bodies and nurse scientists, whom together provide vision and knowledge to support and shape nursing practice. While nursing governance bodies and scientists have contributed a great deal to tobacco reduction, there are also gaps. Areas that require strengthening are: support for tobacco dependent nurses, basic nursing education concerning tobacco dependency treatment, and integration of tobacco dependence treatment into nursing practice.

Hospital- and clinic-based smoking cessation interventions for smokers with cardiovascular disease

Cigarette smoking is the leading preventable cause of death in the United States and a major risk factor for cardiovascular disease (CVD). Large observational epidemiologic studies conducted in diverse populations have demonstrated a strong association between smoking and CVD morbidity and mortality. Observational epidemiologic studies have also demonstrated a substantial benefit of smoking cessation on cardiovascular morbidity and mortality. Smoking cessation after myocardial infarction reduces subsequent cardiovascular mortality by nearly 50%. Therefore, the use of effective strategies to reduce the prevalence of tobacco use is a high priority for both the primary and secondary prevention of CVD. Effective smoking cessation interventions have been identified in randomized controlled trials in the general population of smokers. These methods, which include behavioral counseling and pharmacotherapy, are incorporated into clinical practice guidelines for physicians in the United States and Great Britain. A smaller but still substantial body of evidence demonstrates the efficacy of these interventions in hospital- and clinic-based settings for smokers with CVD. This evidence is sufficient to support the routine implementation of these smoking cessation methods in inpatient and outpatient settings for smokers with CVD.

Interventions for smoking cessation in hospitalised patients

BACKGROUND

An admission to hospital provides an opportunity to help people stop smoking. Individuals may be more open to help at a time of perceived vulnerability, and may find it easier to quit in an environment where smoking is restricted or prohibited. Providing smoking cessation services during hospitalisation may help more people to attempt and sustain a quit attempt.

OBJECTIVES

To determine the effectiveness of interventions for smoking cessation in hospitalised patients.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group register, CINAHL and the Smoking and Health database in March 2002 for studies of interventions for smoking cessation in hospitalised patients, using terms including (hospital and patient*) or hospitali* or inpatient* or admission* or admitted.

SELECTION CRITERIA

Randomised and quasi-randomised trials of behavioural, pharmacological or multicomponent interventions to help patients stop smoking conducted with hospitalised patients who were current smokers or recent quitters. We excluded studies of patients admitted for psychiatric disorders or substance abuse, those that did not report abstinence rates and those with follow-up of less than six months.

DATA COLLECTION AND ANALYSIS

Two authors extracted data independently for each paper, with disagreements resolved by consensus.

MAIN RESULTS

Seventeen trials met the inclusion criteria. Intensive intervention (inpatient contact plus follow-up for at least one month) was associated with a significantly higher quit rate compared to control (Peto Odds Ratio 1.82, 95% CI 1.49-2.22, six trials). Interventions with less than a month of follow-up did not show evidence of significant benefit (Peto Odds Ratio 1.09, 95% CI 0.91-1.31, seven trials). There was no evidence to judge the effect of very brief (<20 minutes) interventions delivered only during the hospital stay. Longer interventions delivered only during the hospital stay were not significantly associated with a higher quit rate (Peto Odds Ratio 1.07, 95% CI 0.79-1.44, three trials). Although the interventions increased quit rates irrespective of whether nicotine replacement therapy (NRT) was used, the results for NRT were compatible with other data indicating that it increases quit rates. There was no strong evidence that clinical diagnosis affected the likelihood of quitting.

REVIEWER'S CONCLUSIONS

High intensity behavioural interventions that include at least one month of follow-up contact are effective in promoting smoking cessation in hospitalised patients. The findings of the review were compatible with research in other settings showing that NRT increases quit rates.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of proactive and reactive telephone support to help smokers quit.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group trials register for studies using free text term 'telephone*' or the keywords 'telephone counselling' or 'Hotlines' or 'Telephone'. Date of the most recent search: September 2002.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters.

DATA COLLECTION AND ANALYSIS

Trials were identified and data extracted by one person and checked by a second. The main outcome measure was abstinence from smoking after at least six months follow-up. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Participants lost to follow-up were considered to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention as the control group in the primary analysis. Where interventions were similar, we performed meta-analysis using a fixed effects model (Peto method) to give an odds ratio.

MAIN RESULTS

Twenty seven trials met inclusion criteria. Thirteen trials compared proactive counselling to a minimal intervention control. There was statistical heterogeneity, with five trials showing a significant benefit, and eight showing non significant differences. The heterogeneity was associated with trials that provided tailored self-help materials to the control group. Meta-analysis using all less intensive intervention arms as the control removed the heterogeneity and suggests that telephone counselling compared to less intensive intervention increases quit rates (OR 1.56, 1.38 - 1.77). Four trials adding telephone support to a face to face intervention control failed to detect a significant effect on long term quit rates. Four trials failed to detect an additional effect of telephone support in users of nicotine replacement therapy. Providing access to a hotline showed a significant benefit in one trial and no significant difference in two. No differences in outcome were detected in trials that compared different types of telephone counselling.

REVIEWER'S CONCLUSIONS

Proactive telephone counselling can be effective compared to an intervention without personal contact. Successful interventions generally involve multiple contacts timed around a quit attempt. The available evidence neither confirms nor rules out a benefit of telephone counselling as an adjunct to face to face counselling or pharmacotherapy. Further trials randomising access to helplines are unlikely to be done but indirect evidence suggests they can be a useful part of a smoking cessation service.

Tobacco Dependence Curricula in Acute Care Nurse Practitioner Education

• Background Tobacco dependence is the leading preventable cause of death in the United States, yet healthcare professionals are not adequately educated on how to help patients break the deadly cycle of tobacco dependence.

• Objective To assess the content and extent of tobacco education in the curricula of acute care nurse practitioner programs in the United States.

• Methods A survey with 13 multiple-choice items was distributed to the coordinators of 72 acute care nurse practitioner programs. The survey was replicated and modified from previous research on tobacco dependence curricula in undergraduate medical education.

• Results Fifty programs (83%) responded to the survey. Overall, during an entire course of study, 70% of the respondents reported that only between 1 and 3 hours of content on tobacco dependence was covered. Seventy-eight percent reported that students were not required to teach smoking-cessation techniques to patients, and 94% did not provide opportunities for students to be certified as smoking-cessation counselors. Sixty percent reported that the national guidelines for smoking cessation were not used as a curriculum reference for tobacco content.

• Conclusions The majority of acute care nurse practitioner programs include brief tobacco education. More in-depth coverage is required to reduce tobacco dependence. Acute care nurse practitioners are in a prime position to intervene with tobacco dependence, especially when patients are recovering from life-threatening events. National recommendations for core tobacco curricula and inclusion of tobacco questions on board examinations should be developed and implemented.

Theoretical applications of smoking cessation interventions to individuals with medical conditions: women's initiative for nonsmoking (WINS)-part III

This paper reviews the Theory of Self-Efficacy, Transtheoretical Model of Readiness for Change, and Theory of Addictions to provide a basis for smoking cessation, and explores how these theories have been used to guide clinical research and clinical interventions. Selected randomized controlled trials of the past ten years are reviewed for demonstrated efficacy, integration of theory into the design of the interventions, and how theories guide analysis. Results show that surprisingly little effort has been put forth to examine and develop these theories within the context of clinical interventions, despite the claims of importance. For example, the relationship between stages of readiness of change and smoking cessation outcome has not been examined. Despite the complexity of smoking behaviors (quitting, relapsing, maintaining, occasional smoking and so on), the concept of self-efficacy was mostly measured on single occasions over the course of most studies reviewed; multiple measurements of concepts were not utilized in the randomized controlled trials. Taking into account the gaps between theory and application, theory driven nursing strategies are offered.

Smoking-cessation counseling in the home. Attitudes, beliefs, and behaviors of home healthcare nurses

BACKGROUND

Despite advances in smoking treatment, cessation rates remain stagnant, possibly a function of the lack of new channels to reach heavily addicted smokers. This cross-sectional study examined home care nurses' attitudes, beliefs, and counseling behaviors regarding counseling their home care patients who smoke.

METHODS

Home healthcare nurses (N=98) from the Visiting Nurse Association of Rhode Island were randomly selected to participate in a study helping home-bound medically ill smokers to quit. At baseline, nurses completed a questionnaire that assessed a constellation of cognitive factors (self-efficacy, outcome expectations, perceived effectiveness, risk perception, motivation, and perceived patient adherence) as correlates of self-reported nurse counseling behaviors.

RESULTS

Nurses with higher outcome expectations spent more time counseling their patients about quitting (p<0.04). Nurses' self-efficacy was the only variable associated with consistent counseling (p<0.05). While the majority of nurses "asked and advised" their patients, a minority of nurses "assisted or arranged" follow-up. Perceived importance of counseling was associated with a greater likelihood of asking, advising and assisting (p<0.05). None of the nurses who currently smoked (n=13) provided follow-up to their patients. Nurses who reported higher levels of both risk perception (regarding the harmful effects of smoking) and perceived effectiveness were more likely to recommend the nicotine patch.

CONCLUSIONS

Attitudes and beliefs about smoking are significantly associated with nurse counseling behaviors. Helping nurses to overcome their barriers to smoking counseling may open up new channels for smoking intervention.

Predictors of tobacco control among nursing students

As the most numerous health care providers, nurses could reduce tobacco-related morbidity and mortality. A cross-sectional survey of 476 junior and senior students at 12 schools of nursing in the New York metropolitan area was conducted, to determine nurse knowledge of tobacco control, their attitudes, beliefs, and practices. Overall, 76% of all nursing students reported that they practiced tobacco control. Current smokers were less likely to participate in tobacco control with targets ranging from the nurse herself to the community than either never or ex-smokers. Nurses were more likely to engage in tobacco control among individual, family, or group clients than to advocate for changes in the community. Student nurses who were African American or Hispanic, had never smoked or were ex-smokers, those who had better knowledge of cessation approaches, and those who tended to have more confidence in their cessation counseling skills were more likely to engage in multi-target tobacco control than other similar nurses. Tailored interventions that emphasize discrete counseling skills are suggested.

Prevention in the inpatient setting

PURPOSE

To review the literature on and describe approaches to implementing health promotion and disease prevention practices in the inpatient setting.

DATA SOURCES

Comprehensive review of nursing and medical literature, clinical practice guidelines, and U.S. government documents.

CONCLUSIONS

Preventive screening has been shown to reduce morbidity and mortality from many diseases. Health promotion and disease prevention activities form the foundation of practice for many nurse practitioners (NPs). As increasing numbers of NPs begin to practice in the acute care setting, it is important they incorporate prevention into the inpatient setting.

IMPLICATIONS FOR PRACTICE

Because there are many barriers that impact appropriate preventive screening, health care providers must take advantage of every patient encounter including those in the inpatient setting. Although it may not be feasible to actually perform certain screening exams while a patient is hospitalized, it is feasible in many cases to take a few minutes to review recommended preventive screening.

Interventions for smoking cessation in hospitalised patients: a systematic review

BACKGROUND

An admission to hospital provides an opportunity to help people stop smoking. Individuals may be more open to help at a time of perceived vulnerability, and may find it easier to quit in an environment where smoking is restricted or prohibited. Providing smoking cessation services during hospitalisation may help more people to attempt and sustain an attempt to quit. The purpose of this paper is to systematically review the effectiveness of interventions for smoking cessation in hospitalised patients.

METHODS

We searched the Cochrane Tobacco Addiction Group register, CINAHL, and the Smoking and Health database for studies of interventions for smoking cessation in hospitalised patients. Randomised and quasi-randomised trials of behavioural, pharmacological, or multi-component interventions to help patients stop smoking conducted with hospitalised patients who were current smokers or recent quitters were included. Studies of patients admitted for psychiatric disorders or substance abuse, those that did not report abstinence rates, and those with follow up of less than 6 months were excluded. Two of the authors extracted data independently for each paper, with assistance from others.

RESULTS

Intensive intervention (inpatient contact plus follow up for at least 1 month) was associated with a significantly higher cessation rate compared with controls (Peto odds ratio (OR) 1.82, 95% CI 1.49 to 2.22). Any contact during hospitalisation followed by minimal follow up failed to detect a statistically significant effect on cessation rate, but did not rule out a 30% increase in smoking cessation (Peto OR 1.09, 95% CI 0.91 to 1.31). There was insufficient evidence to judge the effect of interventions delivered only during the hospital stay. Although the interventions increased quit rates irrespective of whether nicotine replacement therapy (NRT) was used, the results for NRT were compatible with other data indicating that it increases quit rates. There was no strong evidence that clinical diagnosis affected the likelihood of quitting.

CONCLUSIONS

High intensity behavioural interventions that include at least 1 month of follow up contact are effective in promoting smoking cessation in hospitalised patients.

Interventions for smoking cessation in hospitalised patients: a systematic review

BACKGROUND

An admission to hospital provides an opportunity to help people stop smoking. Individuals may be more open to help at a time of perceived vulnerability, and may find it easier to quit in an environment where smoking is restricted or prohibited. Providing smoking cessation services during hospitalisation may help more people to attempt and sustain an attempt to quit. The purpose of this paper is to systematically review the effectiveness of interventions for smoking cessation in hospitalised patients.

METHODS

We searched the Cochrane Tobacco Addiction Group register, CINAHL, and the Smoking and Health database for studies of interventions for smoking cessation in hospitalised patients. Randomised and quasi-randomised trials of behavioural, pharmacological, or multi-component interventions to help patients stop smoking conducted with hospitalised patients who were current smokers or recent quitters were included. Studies of patients admitted for psychiatric disorders or substance abuse, those that did not report abstinence rates, and those with follow up of less than 6 months were excluded. Two of the authors extracted data independently for each paper, with assistance from others.

RESULTS

Intensive intervention (inpatient contact plus follow up for at least 1 month) was associated with a significantly higher cessation rate compared with controls (Peto odds ratio (OR) 1.82, 95% CI 1.49 to 2.22). Any contact during hospitalisation followed by minimal follow up failed to detect a statistically significant effect on cessation rate, but did not rule out a 30% increase in smoking cessation (Peto OR 1.09, 95% CI 0.91 to 1.31). There was insufficient evidence to judge the effect of interventions delivered only during the hospital stay. Although the interventions increased quit rates irrespective of whether nicotine replacement therapy (NRT) was used, the results for NRT were compatible with other data indicating that it increases quit rates. There was no strong evidence that clinical diagnosis affected the likelihood of quitting.

CONCLUSIONS

High intensity behavioural interventions that include at least 1 month of follow up contact are effective in promoting smoking cessation in hospitalised patients.

Smoking cessation interventions among hospitalized patients: what have we learned?

BACKGROUND

We conducted a structured review of controlled studies on inpatient hospital-based smoking cessation interventions.

METHODS

Electronic searches were conducted with two different search engines, and reference sections of articles located were also reviewed. The RE-AIM framework was used to organize the review around the issues of reach, efficacy, adoption, implementation, and maintenance of interventions.

RESULTS

Thirty-one intervention articles were located, 20 of which included a comparison condition and were included in the review. Overall, a moderate number of studies (13/20) reported on reach, which was highly variable and limited (30-50% in most studies), while few reported on implementation (7/20). Longer term cessation results produced relative risk ratios of 0.9-2.3, with a median of 1.5. Increases in quit rates above the control condition ranged from -1 to 10% (median 4%) among general admission patients and from 7 to 36% (median 15%) among cardiac admission patients. Studies with a dedicated smoking cessation counselor and 3-5 months of relapse prevention had a significant impact on cessation rates. Study settings (adoption) were limited to university, Veterans affairs, and HMO hospitals. Maintenance at the individual level was variable and related to the presence of a relatively intensive initial intervention and a sustained relapse prevention intervention.

CONCLUSIONS

Efficacious inpatient smoking programs have been developed and validated. The challenge now is to translate these interventions more widely into practice, given changing hospitalization patterns.

Smoking cessation in the hospitalized patient using the transtheoretical model of behavior change

Tobacco use continues to be the most prevalent cause of preventable morbidity and mortality in the United States, causing more than 430,000 deaths each year, or 1 in every 5 deaths. In addition, many health care providers employed in critical care settings deal with patients who have experienced a near-death event that has led them to consider smoking cessation. The smoking cessation rate 1 year after a myocardial infarction is approximately 70% in those patients who receive a smoking cessation intervention. Theory-based smoking cessation interventions have been found to be effective. The purpose of this article is to present the transtheoretical model as basis for developing a hospital-based smoking cessation intervention. In addition, symptom management options will be discussed.

Reviews of evidence regarding interventions to reduce tobacco use and exposure to environmental tobacco smoke

This report presents the results of systematic reviews of effectiveness, applicability, other effects, economic evaluations, and barriers to use of selected population-based interventions intended to reduce tobacco use and exposure to environmental tobacco smoke. The related systematic reviews are linked by a common conceptual approach. These reviews form the basis of recommendations by the Task Force on Community Preventive Services (TFCPS) regarding the use of these selected interventions. The TFCPS recommendations are presented on page 67 of this supplement.

Implementation and effectiveness of a brief smoking-cessation intervention for hospital patients

OBJECTIVES

Previous research has documented that hospital-based smoking-cessation counseling is efficacious and cost-effective when delivered by research staff. This study evaluated the implementation and effectiveness of this intervention program when delivered by respiratory therapists chosen from the regular hospital staff.

METHODS

A total of 1,173 hospitalized smokers were randomly assigned to either usual care or a stage-based bedside counseling program supplemented with a videotape, self-help materials, and a follow-up telephone call.

RESULTS

Using an intent-to-treat analysis and counting those lost to follow-up as smokers, we did not find a significant difference in outcome between intervention (14.2% reported being abstinent for > or =6 months at the 1-year follow-up) and usual care conditions (13.6% abstinence). Process analyses revealed that these results were due to a combination of failure to reach many patients and reduced effectiveness of respiratory therapist interventionists compared with experienced professional counselors in a previous study conducted in the same hospitals.

CONCLUSIONS

We recommend implementation of hospital-based smoking-cessation counseling by professional counselors whose primary responsibility is to deliver the intervention. Recommendations for future research and for innovative ways to reach hospitalized smokers who are not receiving intervention are discussed.
