Effectiveness Of Smoking Cessation Counseling Research Articles

Effectiveness of a smoking cessation educational program for Japanese nurses on subsequent changes of behavior in delivering smoking cessation counseling.

INTRODUCTIONDespite the effectiveness of smoking cessation counseling, participation of nurses in delivering smoking cessation advice has been far from satisfactory in practice. Training nurses is considered to be important for increasing self-efficacy and skills for routine delivery of smoking cessation counseling. The aim of the present study was to evaluate the effectiveness of a smoking cessation educational program for Japanese nurses on subsequent changes of their behavior in delivering smoking cessation counseling, three months later.METHODSWe ran a 6-hour smoking cessation educational program for nurses recruited from the Nursing Associations of 13 prefectures in Japan between May 2019 and February 2020. Surveys were conducted by questionnaire before the start of the program and 3 months thereafter. The successful implementation of smoking cessation counseling behavior was evaluated according to the 5As of the Clinical Practice Guidelines for Treating Tobacco Use and Dependence (Ask, Advise, Assess, Assist, Arrange).RESULTSWe received 289 responses 3 months after the program finished (response rate 46.0%). At that time, 43% of participants had increased the frequency of ‘Ask’ and 42.1%, 50%, 39.3%, and 28.6%, respectively, had also increased their frequency of ‘Advise’, ‘Assess’, ‘Assist’, and ‘Arrange’. We found that smoking cessation counseling was significantly more frequently delivered after the educational program for those participants who had routinely delivered ‘Advise’ before the program as measured by increased delivery of ‘Assess’ and ‘Assist’ afterwards (OR=2.39; 95% CI: 1.00–5.69, OR=2.54; 95% CI: 1.16–5.60 and OR=3.68; 95% CI: 1.40–9.65, OR=2.77; 95% CI: 1.10–7.01, respectively).CONCLUSIONSThe program successfully increased the frequency of nurses providing smoking cessation advice to patients. Readiness to deliver smoking cessation counseling before the program and continuing self-efficacy after the program are important for changing the behavior of nurses in delivering smoking cessation counseling.

Two-Year Follow-Up of a Randomized Controlled Study of Integrated Smoking Cessation in a Lung Cancer Screening Program

IntroductionSmoking cessation activities incorporated into lung cancer screening programs have been broadly recommended, but studies to date have not exhibited increased quit rates associated with cessation programs in this setting. We aimed to determine the long-term effectiveness of smoking cessation counseling in smokers presenting for lung cancer screening. MethodsThis was a randomized control trial of an intensive, telephone-based smoking cessation counseling intervention incorporating lung cancer screening results versus usual care (information pamphlet). This analysis reports on the long-term impact (24-mo) of the intervention on abstinence from smoking. ResultsA total of 337 active smokers who participated in the screening study were randomized to active smoking cessation counseling (n = 171) or control arm (n = 174) and completed a 24-month assessment. The 30-day smoking abstinence rates at 24 months postrandomization was 18.3% and 21.4% in the control and intervention arms, respectively—a 3.1% difference (95% confidence interval: −5.4 to 11.6, p = 0.48). No statistically significant differences in the 7-day abstinence, the use of pharmacologic cessation aids, nicotine replacement therapies, nor intent to quit in the following 30 days were noted (p > 0.05). The abstinence rates at 24-months were higher overall than at 12-months (19.9% versus 13.3%, p < 0.001), and smoking intensity was lower than at baseline for ongoing smokers. ConclusionsA telephone-based smoking cessation counseling intervention incorporating lung cancer screening results did not result in increased long-term cessation rates versus written information alone in unselected smokers undergoing lung cancer screening. Overall, quit rates were high and continued to improve throughout participation in the screening program. (ClinicalTrials.govNCT02431962).

Variance estimation when using propensity-score matching with replacement with survival or time-to-event outcomes.

Propensity‐score matching is a popular analytic method to estimate the effects of treatments when using observational data. Matching on the propensity score typically requires a pool of potential controls that is larger than the number of treated or exposed subjects. The most common approach to matching on the propensity score is matching without replacement, in which each control subject is matched to at most one treated subject. Failure to find a matched control for each treated subject can lead to “bias due to incomplete matching.” To avoid this bias, it is important to identify a matched control subject for each treated subject. An alternative to matching without replacement is matching with replacement, in which control subjects are allowed to be matched to multiple treated subjects. A limitation to the use of matching with replacement is that variance estimation must account for both the matched nature of the sample and for some control subjects being included in multiple matched sets. While a variance estimator has been proposed for when outcomes are continuous, no such estimator has been proposed for use with time‐to‐event outcomes, which are common in medical and epidemiological research. We propose a variance estimator for the hazard ratio when matching with replacement. We conducted a series of Monte Carlo simulations to examine the performance of this estimator. We illustrate the utility of matching with replacement to estimate the effect of smoking cessation counseling on survival in smokers discharged from hospital with a heart attack.

A Randomized Controlled Study of Integrated Smoking Cessation in a Lung Cancer Screening Program

IntroductionSmoking cessation activities incorporated into lung cancer screening programs have been broadly recommended, but studies to date have not shown increased quit rates associated with cessation programs in this setting. We aimed to determine the effectiveness of smoking cessation counseling in smokers presenting for lung cancer screening. MethodsThis study is a randomized control trial of an intensive telephone-based smoking cessation counseling intervention incorporating lung cancer screening results versus usual care (information pamphlet). All active smokers enrolled in the Alberta Lung Cancer Screening Study cohort were randomized on a 1:1 ratio with a primary endpoint of self-reported 30-day abstinence at 12 months. ResultsA total of 345 active smokers participating in the screening study were randomized to active smoking cessation counseling (n = 171) or control arm (n = 174). Thirty-day smoking abstinence at 12 months post-randomization was noted in 22 of 174 (12.6%) and 24 of 171 (14.0%) of participants in the control and intervention arms, respectively, a 1.4% difference (95% confidence interval: -5.9 to 8.7, p = 0.7). No statistically significant differences in 7-day or point abstinence were noted, nor were differences at 6 months or 24 months. ConclusionsA telephone-based smoking cessation counseling intervention incorporating lung cancer screening results did not result in increased 12-month cessation rates versus written information alone in unselected smokers undergoing lung cancer screening. Routine referral of all current smokers to counseling-based cessation programs may not improve long-term cessation in this patient cohort. Future studies should specifically focus on this subgroup of older long-term smokers to determine the optimal method of integrating smoking cessation with lung cancer screening (clinicaltrials.govNCT02431962).

A randomized clinical trial of counseling and nicotine replacement therapy for treatment of African American non-daily smokers: Design, accrual, and baseline characteristics

BackgroundNon-daily smokers (NDS) who smoke on some but not all days are a growing subset of United States (US) tobacco users. Racial/ethnic minorities are more likely to be NDS. African American NDS have strikingly high levels of nicotine and carcinogen exposure, making treatment of this high risk group a priority. MethodsThe current study is one of three ongoing federally-funded clinical trials of NDS and, to our knowledge the only RCT focused on racial/ethnic minority NDS. The design has been guided by input from Patient and Stakeholder Advisory Panels who helped develop the research questions, design the intervention, and select the outcomes. The objective is to compare the effectiveness of smoking cessation counseling alone (C) or smoking cessation counseling plus participant's choice of nicotine replacement therapy (NRT; C + NRT) for African American NDS. Two-hundred seventy-eight African American NDS will be randomized in a 2:1 fashion to C + NRT or C. All participants receive five sessions of smoking cessation counseling; those randomized to C + NRT receive their choice of nicotine gum, patch, and/or lozenge. Treatment in both groups lasts for 12 weeks. We hypothesize that C + NRT will be more effective than C on the primary outcome of biochemically-confirmed abstinence from smoking at week 12. Secondary aims will compare C + NRT and C on patient- and provider-desired outcomes including abstinence from smoking at week 26, change in biochemically-verified nicotine and carcinogen exposure, days abstinent, and treatment process measures (e.g., NRT use and side effects). Predictors of abstinence will also be explored. DiscussionFindings will illuminate effective treatment options for African American NDS and contribute to development of evidence-based guidelines for treating the 8.9 million US adult NDS for whom no guidelines currently exist.TRIAL REGISTRATION NUMBER: ClinicalTrials.gov: NCT02244918

Effect of smoking cessation counseling within a randomised study on early detection of lung cancer in Germany.

In the German lung cancer screening trial LUSI, smoking cessation counseling (SCC) was offered to all participants at time of randomization, and smoking habits were asked for within annual questionnaire inquiries. We analyzed the smoking habits of the participants within the first 2 years of follow-up and especially the potential effect of the SCC on these habits. We used the smoking data of the initial inquiry on which the decision on invitation to the study was based, the socio-economic data of the questionnaire filled-in at time of randomization, the psycho-social data obtained during the SCC, and the annual questionnaire data of the first two annual follow-up screening rounds. Smoking prevalence decreased in the entire cohort significantly by 4 %, whereby the decrease was with 4.5 % statistically not significantly higher in the control arm than in the screening arm with 3.4 %. The decline was much stronger in the subgroup of attendees to stop-smoking counseling and mounted up therein to 10 %. In some participants, an increase of readiness to quit smoking was observed during the counseling hour, but did not show effects on smoking status 2 years later. We did not see a tendency to increased smoking among participants of the intervention arm or the entire study. The decline of smoking prevalence among the attendees of the counseling might be due to self-selection. Since the issue of effectiveness of smoking cessation counseling is important, further research with randomization into offering counseling or no intervention should be taken into consideration.

Intervenciones de consejería para la cesación de la adicción al tabaco: revisión sistemática de la literatura

A systematic review on efficacy and safety of smoking cessation counseling was developed. The ADAPTE methodology was used with a search of Clinical Practice Guidelines (CPG) in Medline, EMBASE, CINAHL, LILACS, and Cochrane. DELBI was used to select CPG with score over 60 in methodological rigor and applicability to the Colombian health system. Smoking cessation rates at 6 months were assessed according to counseling provider, model, and format. In total 5 CPG out of 925 references were selected comprising 44 systematic reviews and meta-analyses. Physician brief counseling and trained health professionals' intensive counseling (individual, group, proactive telephone) are effective with abstinence rates between 2.1% and 17.4%. Only practical counseling and motivational interview were found effective intensive interventions. The clinical effect of smoking cessation counseling is low and long term cessation rates uncertain. Cost-effectiveness analyses are recommended for the implementation of counseling in public health programs.

Are emergency department visits really a teachable moment? Smoking cessation promotion in emergency department

To compare the effectiveness of smoking cessation counseling in the emergency department (ED) versus in outpatient clinics (OCs) setting. Over a 3-month period, smokers and recent quitters presenting to ED or OCs were questioned about their smoking habits and desire to quit. They also completed the Fagerstrom Test for Nicotine Dependence (FTND) questionnaire and Prochaska's stages of change (PSC) survey. Standardized 5 min counseling session was carried out, and stop smoking pamphlet and phone number of the hospital's smoking cessation unit were given. One month after initial counseling, patients were telephoned, FTND, PSC, desire to quit, and daily cigarette consumption were asked. Data from those unable to be contacted within 6 weeks were excluded from analysis. Of the 392 patients (197 ED, 195 OC) counseled initially, 340 (87%) were reached for telephone follow-up. Counseling was effective in both groups: FTND and PSC scores had improved, and daily cigarette consumption decreased significantly (17.17-12.49 cigs/day; P=0.000). Smokers counseled in the ED were found more inclined to stop smoking compared with smokers who counseled in OCs, after 1 month of the intervention (95% confidence interval=14.7-7.5%; P=0.051). Only one patient (0.6%) from the ED and 10 (6.6%) from the OC attended the smoking cessation program. ED-based counseling for smoking cessation was as effective as that performed in the OC setting. Referral of smokers from the ED to a smoking cessation program was unsuccessful in our patient population.

The effects of smoking cessation counseling by midwives on Dutch pregnant women and their partners

Objective Smoking during pregnancy is an important problem in the Netherlands. We tested the effectiveness of a health counseling method by midwives using a RCT. Methods Four provinces with 42 practices including 118 midwives were randomly assigned to the experimental or control condition. Midwives in the experimental group provided brief health counseling, self-help materials on smoking cessation during pregnancy and early postpartum, and a partner booklet. Controls received routine care. The main outcome measures were 7-day abstinence, continuous abstinence, and partner smoking at 6 weeks post-intervention (T1) and 6 weeks postpartum (T2). Results Multi-level analysis revealed significant differences between both conditions at T1 and T2 using intention-to-treat analysis. Nineteen percent of the experimental group reported 7-day abstinence compared to 7% of the control group at T1, and 21 and 12%, respectively, at T2. For continuous abstinence these percentages were 12% in the experimental group and 3% in the control group. The partner intervention was not successful. Conclusion The intervention resulted in significant effects on smoking behavior for pregnant women, but not for partner smoking. Practice implications The program realized short-term effects. An important precondition is that midwives need a proper training.

Australian dental students' views about smoking cessation counseling and their skills as counselors.

This paper seeks to determine Australian dental students' views about and skills to provide smoking cessation counseling. In 2000, we surveyed dental students enrolled in all five years of the undergraduate degree course at the Faculty of Dentistry, University of Sydney, Australia. We obtained 248 questionnaires (response rate=88%). Of our sample, 31 (13%) were self-reported current smokers. Most students (n=203; 82%) indicated they were expected to give smoking cessation counseling to patients. While the majority responded they had been taught the risks from tobacco in the etiology of oral cancer (n=180; 73%), significantly fewer (n=111; 45%) indicated they were taught smoking cessation counseling (McNemars chi-square=41.66; df=1; P<.001). Independent of their own smoking status, most planned to advise patients about tobacco use in their graduate careers (n=219; 91%). However, significantly fewer (n=129; 54%) indicated that such counseling would be effective (McNemars chi-square=9.95; df= 1; P<.04). Students' confidence to counsel smokers to quit was low and did not differ significantly by year (chi-square=3.90; df=4; P=.42). Resources highly ranked for inclusion in the undergraduate curriculum were seminars with experts (50%) and practical skills training (49%). Dental students' low perception of the effectiveness of smoking cessation counseling and the inadequacies of the current evidence-base invite more convincing research about dentists' role in tobacco control and better skills training in response.
