Ten-year experience of smoking cessation in a single center in Japan

"A person who do not smoke will not understand a person who smokes and trying to quit…" Insights From Quit Smoking Clinics' Defaulters: A Qualitative Study

This study explored the factors contributing to discontinuation of people who smoke (PWS) from quit smoking clinic prior to achieving 6-month abstinence. Fifteen active PWS were interviewed via telephone and face-to-face. Interviews were audio-recorded, transcribed and analysed using thematic analysis. At individual level, low intrinsic motivation including unreadiness to quit, low self-efficacy and ambivalence on smoking cessation were barriers to attain successful cessation. Influence of extrinsic factors such as work-related factors, social interaction and ill-health burden lead to poor commitment with QSC. At the clinic level, healthcare professional's competency, personal attributes, pharmacotherapy's efficacy, safety and availability were important components that may affect a participant's effort to quit. Working commitment was highlighted as the primary barrier for a successful cessation. Hence, effective intervention and collaborative effort between healthcare facilities and employers are essential to optimise cessation adherence among employees who smoke which subsequently will enhance their abstinence rates.

Smoking Cessation Programs for Pregnant Women: Utilizing WhatsApp Text Messaging

OBJECTIVE

This study aimed to develop a Transtheoretical-Model-based and WhatsApp-text-message-supported smoking cessation program for pregnant women and to evaluate its effectiveness.

METHODS

This study is a pretest-posttest designed, randomized controlled and quasi-experimental intervention research. The study was conducted on 50 pregnant women, 25 of them in the intervention group and 25 of them in the control group. A theory-based motivational individual counseling initiative has been applied to the intervention group, and WhatsApp text messages have been sent 3 days a week, in accordance with the stages of change to support the interviews.

RESULTS

In the final follow-up, 60% of pregnant women in the intervention group and 36% of pregnant women in the control group quit smoking. All participants indicated they would recommend the WhatsApp-text-message-supported smoking cessation program. Transtheoretical-Model-based and WhatsApp-text-message-supported smoking cessation programs were found to be effective in reducing nicotine dependency scores and carbon monoxide levels of pregnant women and quitting smoking.

PRACTICE IMPLICATIONS

The smoking cessation program used in the research may be applied by midwives or nurses trained on the subject to help pregnant women quit smoking.

Smoking Cessation at the Community Pharmacy: Determinants of Success from a Real-Life Practice

The objectives of this study are to report the contribution of pharmacists to smoking cessation and study the determinants of smoking cessation success in eight pharmacies in Portugal (south) between 2009 and 2019. A real-life study was conducted with a sample of smokers who participated in pharmacist consultations. The sample included 135 smokers (average age of 47.9 ± 1.21 years), 79 (58.5%) of whom were male. In parallel with the motivation and behavioral approach, 116 (85.9%) smokers received pharmacological therapies: 108 (80.0%) were treated with nicotine replacement products and eight (5.9%) with non-nicotine medications. The interventions resulted in 70 (51.9%) smokers complying with the quit day, of whom 59 (43.7%) were smoking-abstinent at the end of the first month. Success rates were reduced to 32.6%, 28.1%, and 20.7% at the end of the 3rd, 6th, and 12th months, respectively. Smoking cessation was more successful for the participants receiving pharmacological therapies (Fisher’s exact test, p < 0.001) and those who participated in more pharmacist consultations (χ² = 59.994, p < 0.001) and more telephone sessions (χ² = 17.845, p < 0.001). Pharmacists can contribute significantly to the promotion of smoking cessation. Smokers who are more thoroughly followed up by pharmacists showed increased success rates when compared with smokers having fewer sessions with pharmacists.

Nomogram to predict successful smoking cessation in a Chinese outpatient population

INTRODUCTION

The study aimed to establish and internally validate a nomogram to predict successful smoking cessation in a Chinese outpatient population.

METHODS

A total of 278 participants were included, and data were collected from March 2016 to December 2018. Predictors for successful smoking cessation were evaluated by 3-month sustained abstinence rates. Least absolute shrinkage and selection operator (LASSO) regression was used to select variables for the model to predict successful smoking cessation, and multivariable logistic regression analysis was performed to establish a novel predictive model. The discriminatory ability, calibration, and clinical usefulness of the nomogram were determined by the concordance index (C-index), calibration plot, and decision curve analysis, respectively. Internal validation with bootstrapping was performed.

RESULTS

The nomogram included living with a smoker or experiencing workplace smoking, number of outpatient department visits, reason for quitting tobacco, and varenicline use. The nomogram demonstrated valuable predictive performance, with a C-index of 0.816 and good calibration. A high C-index of 0.804 was reached with interval validation. Decision curve analysis revealed that the nomogram for predicting successful smoking cessation was clinically significant when intervention was conducted at a successful cessation of smoking possibility threshold of 19%.

CONCLUSIONS

This novel nomogram for successful smoking cessation can be conveniently used to predict successful cessation of smoking in outpatients.

Outcomes and predictive factors for successful smoking cessation therapy in COPD patients with nicotine dependence

BACKGROUND

The data on smoking cessation treatment outcomes for smokers with chronic obstructive pulmonary disease (COPD) are limited. The present study assessed the effectiveness of smoking cessation interventions at our clinic.

METHODS

Data from a prospective registry of a 3-month smoking cessation program were evaluated. The primary outcome, smoking cessation, was defined as the complete abstinence from smoking between the 8-week and 12-week clinic visits. Pulmonary function and health-related quality of life using St. George's Respiratory Questionnaire (SGRQ) were assessed at baseline and at the end of the program.

RESULTS

Out of the 155 COPD patients with nicotine dependence (female/male = 39/116; mean age, 67.2 ± 9.8 years; mean forced expiratory volume in 1 s (FEV1), 59.7 ± 21.1% predicted), 107 participants completed the program. Among the completers, 74 achieved smoking cessation. In the multivariate analysis, mental disorders (odds ratio [OR] 3.678, 95% confidence interval [CI]: 1.182, 11.445), higher exhaled carbon monoxide (CO) level (OR 1.080, 95% CI: 1.013, 1.151) and lower FEV1/forced vital capacity (FVC) (OR 0.958, 95% CI: 0.923, 0.995) were negatively associated with successful smoking termination. Significant changes in pulmonary function were found in quitters but not in continuous smokers (increases in FEV1 by 0.09 L/s [95% CI: 0.03, 0.15] and peak expiratory flow by 0.23 L/s [95% CI: 0.01, 0.44]). SGRQ total scores improved significantly in both quitters (-5.4 [95% CI: -8.4, -2.5]) and continuous smokers (-7.0 [95% CI: -11.6, -2.5]).

CONCLUSION

In the program completers, the exhaled CO levels, FEV1/FVC ratio, and presence of mental disorders were significantly associated with program success or failure in COPD patients with nicotine dependence.

Factors associated with smoking cessation and relapse in the Japanese smoking cessation treatment program: A prospective cohort study based on financial support in Suita City, Japan

INTRODUCTION

The purpose of this study is to clarify the effect of providing financial support and factors associated with smoking cessation and relapse in the Japanese smoking cessation treatment (SCT) program based on financial support.

METHODS

A prospective cohort study was conducted at the smoking cessation outpatients of hospitals or clinics in Suita City, Japan from May 2017 to September 2018. In all, 153 participants were recruited and received standardized treatment based on the SCT program. Participants were required to answer four questionnaires and register for the financial support program. Chi-squared test, Fisher’s exact test, non-paired t-test and log-binomial regression analysis were used to analyze the data.

RESULTS

Of the 153 participants, 140 participants completed a 12-week treatment and the completion rate was 91.5%. There were no factors significantly associated with smoking cessation and relapse (p<0.05). However, male, cigarettes smoked per day, having present diseases, having previous abstinence, living with family, cohabitation with smokers, desire to smoke at the start of treatment, self-efficacy at the start of treatment, desire to smoke at 4 weeks and self-efficacy at 4 weeks showed statistically significant odds ratio for success of smoking cessation. Similarly at 12 weeks, male, age at smoking initiation, cigarettes smoked per day, having previous abstinence, living with family, cohabitation with smokers, desire to smoke, self-efficacy and depression disorders showed statistically significant odds ratio for smoking relapse. In addition, the rate of abstainers using varenicline was 68.60%, which was higher than abstainers using nicotine patch (55.60%) and the relapse rate of participants using nicotine patch was 100.00%, significantly higher than for relapsers using varenicline (45.80%).

CONCLUSIONS

Further study is expected to clarify the effect of providing financial support and the factors associated with smoking cessation and relapse in the SCT program based on financial support.
