Abstract: Evidence is mixed on whether timing of a target quit date (TQD) has an effect on quit success. The purpose of this secondary analysis of data from a prospective longitudinal study was to determine if time to TQD was a predictor of smoking abstinence at follow-up. Between 2011 and 2013, a total of 5,793 adult smokers participated in a 1-hr psychoeducation workshop and received 5 weeks of nicotine patch treatment. All participants were required to indicate a TQD within 1 month of the workshop. Latency to TQD was categorized into quartiles: 0 to 1 day (first quartile: 28.1%) 2 to 6 days (second quartile: 22.4%) 7 to 19 days (third quartile: 25.4%) 20-31 days (fourth quartile: 24.0%). Compared with participants who chose an immediate TQD within 1 day of the workshop, odds of having quit smoking at end-of-treatment and 6-month follow-up did not significantly differ among those who set a TQD within 2-6 days (5-weeks: adjusted odds ratio [AOR] = 0.89, p = .315 6-months: AOR = 0.89, p = .417), but were significantly lower for those who chose a TQD either 7-19 days (5-weeks: AOR = 0.76, p = .023 6-months: AOR = 0.70, p = .013) or 20-31 days (5-weeks: AOR = 0.64, p = .001 6-months: AOR = 0.69, p = .017) after the workshop. TQD timing was an independent predictor of smoking cessation outcomes after controlling for potential confounding variables including confidence in quitting ability, importance of quitting, nicotine dependence, and number of nicotine patches used.

Abstract: In iduals with concurrent tobacco dependence and other addictions often report symptoms of low mood and depression and as such may have more difficulty quitting smoking. We hypothesized that current symptoms of depression would be a significant predictor of quit success among a group of smokers receiving in idualized treatment for tobacco dependence within addiction treatment settings. In iduals in treatment for other addictions were enrolled in a smoking cessation program involving brief behavioral counseling and in idualized dosing of nicotine replacement therapy. The baseline assessment included the Patient Health Questionnaire (PHQ9) for depression. Smoking cessation outcomes were measured at 3 and 6 months post-enrollment. Bivariate associations between cessation outcomes and PHQ9 score were analyzed. Of the 1,196 subjects enrolled to date, 1,171 (98%) completed the PHQ9. Moderate to severe depression (score >9) was reported by 28% of the s le, and another 29% reported mild depression (score between 5 and 9). Contrary to the extant literature and other findings by our own group, there was no association between current depression and cessation outcome at either 3 months (n = 1,171) (17.0% in those with PHQ9 > 9 vs. 19.8% in those with PHQ9 < 5, p = .32) or 6 months (n = 834) (17.8% vs. 18.9%, p = .74). Contrary to our hypothesis, depression severity as measured by the PHQ9 did not predict cessation outcome in this clinical population. A possible explanation may be the in idualized treatment and supportive environment of an addictions treatment setting. These data indicate that patients in an addictions treatment setting can successfully quit smoking regardless of current depressive symptoms.

Abstract: Electronic cigarettes (e-cigarettes) are being used as cessation aids by many smokers despite a lack of empirical evidence regarding their safety and efficacy. We analyzed the association of e-cigarette use and smoking abstinence in a population of smokers accessing standard smoking cessation treatment (nicotine replacement therapy [NRT] plus behavioral counseling) through primary care clinics in Ontario, Canada. Participants were recruited through 187 primary care clinics across Ontario, Canada and were eligible for up to 26 weeks of brief behavioral counseling and in idualized dosing of NRT at no cost. Adjusted logistic regression models were used to examine the association between concurrent e-cigarette use and smoking abstinence at 3- and 6-month follow-ups. Of the 6526 participants who completed a 3-month follow-up, 18.1% reported using an e-cigarette while in treatment. The majority of e-cigarette users (78.2%) reported using an e-cigarette for smoking cessation. At 3-month follow-up, e-cigarette use was negatively associated with abstinence after controlling for confounders (adjusted odds ratio [AOR] = 0.706, p < .001, 95% confidence interval [CI] = 0.607-0.820). E-cigarette use was also negatively associated with abstinence at 6-month follow-up (AOR = 0.502, p < .001, 95% CI = 0.393-0.640). E-cigarette use was negatively associated with successful quitting in this large community s le of smokers accessing standard evidence-based smoking cessation treatment through primary care clinics, even after adjusting for covariates such as severity of tobacco dependence, gender, and age. The findings suggest that concurrent use of e-cigarettes with NRT may harm cessation attempts. This study confirms previous findings from observational studies regarding the negative association between e-cigarette use and smoking cessation, but in a large cohort of smokers enrolled in an evidence-based treatment program. The implications of these findings are that concurrent use of e-cigarettes during a quit attempt utilizing cost-free evidence-based treatment (NRT plus behavioral counseling) does not confer any added benefit and may h er successful quitting.

Abstract: Although brief alcohol intervention can reduce alcohol use for both men and women, health care providers (HCPs) are less likely to discuss alcohol use or deliver brief intervention to women compared to men. This secondary analysis examined whether previously reported outcomes from a cluster randomized trial of a clinical decision support system (CDSS)—prompting delivery of a brief alcohol intervention (an educational alcohol resource) for patients drinking above cancer guidelines—were moderated by patients’ sex. Patients (n = 5702) enrolled in a smoking cessation program at primary care sites across Ontario, Canada, were randomized to either the intervention (CDSS) or control arm (no CDSS). Logistic generalized estimating equations models were fit for the primary and secondary outcome (HCP offer of resource and patient acceptance of resource, respectively). Previously reported results showed no difference between treatment arms in HCP offers of an educational alcohol resource to eligible patients, but there was increased acceptance of the alcohol resource among patients in the intervention arm. The results of this study showed that these CDSS intervention effects were not moderated by sex, and this can help inform the development of a scalable strategy to overcome gender disparities in alcohol intervention seen in other studies.
