Six Month Abstinence Heterogeneity in the Best Quit Study.

BACKGROUND: Understanding the characteristics of smokers who are successful in quitting may help to increase smoking cessation rates. PURPOSE: To examine heterogeneity in cessation outcome at 6 months following smoking cessation behavioral counseling with or without weight management counseling. METHODS: 2,540 smokers were recruited from a large quitline provider and then randomized to receive proactive smoking cessation behavioral counseling without or with two versions of weight management counseling. A Classification and Regression Tree (CART) analysis was conducted to identify the individual pretreatment and treatment characteristics of groups of smokers with different quitting success (as measured by point prevalence of self-reported smoking of any amount at 6 months). RESULTS: CART analysis identified 10 subgroups ranging from 25.5% to 70.2% abstinent. The splits in the CART tree involved: the total number of counseling and control calls received, whether a smoking cessation pharmacotherapy was used, and baseline measures of cigarettes per day, confidence in quitting, expectation that the study would help the participant quit smoking, the motivation to quit, exercise minutes per week, anxiety, and lack of interest or pleasure in doing things. Costs per quitter ranged from a low of $US270 to a high of $US630. Specific treatment recommendations are made for each group. CONCLUSIONS: These results indicate the presence of a substantial variation in abstinence following treatment, and that the total extent of contact via counseling calls of any type and baseline characteristics, rather than assigned treatment, were most important to subgroup membership and abstinence. Tailored treatments to subgroups who are at high risk for smoking following a quit attempt could increase successful smoking cessation.

Impact of baseline weight on smoking cessation and weight gain in quitlines.

BACKGROUND: The use and effectiveness of tobacco quitlines by weight is still unknown. PURPOSE: This study aims to determine if baseline weight is associated with treatment engagement, cessation, or weight gain following quitline treatment. METHODS: Quitline participants (n = 595) were surveyed at baseline, 3 and 6 months. RESULTS: Baseline weight was not associated with treatment engagement. In unadjusted analyses, overweight smokers reported higher quit rates and were more likely to gain weight after quitting than obese or normal weight smokers. At 3 months, 40 % of overweight vs. 25 % of normal weight or obese smokers quit smoking (p = 0.01); 42 % of overweight, 32 % of normal weight, and 33 % of obese quitters gained weight (p = 0.05). After adjusting for covariates, weight was not significantly related to cessation (approaching significance at 6 months, p = 0.06) or weight gain. CONCLUSIONS: In the first quitline study of this kind, we found no consistent patterns of association between baseline weight and treatment engagement, cessation, or weight gain.

The impact of a free nicotine patch starter kit on quit rates in a state quit line.

All states offer telephone quit lines but they are under-used in part because of the costs associated with promotion. Offering nicotine replacement therapy (NRT) as well as behavioral counseling can increase treatment participation and abstinence rates, but is expensive. Offering less than a full NRT 8-week course can also generate calls to the quit line but less is known about its impact on program outcomes. In October 2004, Oregon--a state with over 3 million people, 500,000 smokers, and a state-funded quit line--introduced the Free Patch Initiative: a free 2-week introductory supply of NRT with phone counseling offered to all callers. We examined the impact of this intervention among insured callers. Most (97.2%) requested free patches, 86.2% used them, and 47.2% obtained additional patches on their own. Six-month outcome data were obtained from insured quit line participants before (n = 268) and after (n = 614) the Initiative launched. Compared with pre-Initiative controls, Free Patch participants were more satisfied with the quit line (84.8% vs. 89.8%; p = .04) and had higher 7-day quit rates using the assumption that eligible nonrespondents are smokers (9.3% vs. 17.0%, OR = 2.0; 95% CI 1.4-2.8) and using respondent only analysis (19% vs. 33.6%, OR = 2.15; 95% CI 1.52-3.04). Offering a free direct mail starter pack of NRT along with telephone counseling is an effective, cost-sharing method for promoting quit line use, enhancing participant satisfaction, and increasing the reach and effectiveness of quit lines among quit line callers with health insurance.

How the Women's Health Initiative (WHI) influenced physicians' practice and attitudes.

BACKGROUND: The landmark Women's Health Initiative (WHI) Postmenopausal Hormone Therapy Trial published in 2002 showed that the health risks of combination hormone therapy (HT) with estrogen and progestin outweighed the benefits in healthy postmenopausal women. Dissemination of results had a major impact on prescriptions for, and physician beliefs about HT. No study has fully examined the influence of the widely publicized WHI on physicians' practice and attitudes or their opinions of the scientific evidence regarding HT; in addition, little is known about how physicians assist women in their decisions regarding HT. DESIGN AND PARTICIPANTS: We conducted in-depth telephone interviews with family practitioners, internists, and gynecologists from integrated health care delivery systems in Washington State (n = 10 physicians) and Massachusetts (n = 12 physicians). Our objectives were to obtain qualitative information from these physicians to understand their perspectives on use of HT, the scientific evidence regarding its risks and benefits, and counseling strategies around HT use and discontinuation. APPROACH: We used Template Analysis to code transcribed telephone interviews and identify themes. RESULTS: Physicians were conflicted about the WHI results and its implications. Seven themes identified from in-depth interviews suggested that the WHI (1) was a ground-breaking study that changed clinical practice, including counseling; (2) was not applicable to the full range of patients seen in clinical practice; (3) raised concerns over the impact of publicized health information on women; (4) created uncertainty about the risks and benefits of HT; (5) called for the use of decision aids; (6) influenced discontinuation strategies; and (7) provided an opportunity to discuss healthy lifestyle options with patients. As a result of the WHI, physicians reported they no longer prescribe HT for prevention and were more likely to suggest discontinuation, although many felt women should be in charge of the HT decision. CONCLUSIONS: Physicians varied in their opinions of HT and the scientific evidence (positive and negative). Whereas the WHI delineated the risks and benefits of HT, physicians reported that decision aids are needed to guide discussions with women about menopause and HT. Better guidance at the time of WHI study publication might have been valuable to ensure best practices.

Depressed mood and smoking experimentation among preteens.

The authors examined children's depressed mood, parental depressed mood, and parental smoking in relation to children's smoking susceptibility and experimentation over 20 months in a cohort of 418 preteens (ages 10-12 at baseline) and their parents. Depressed mood in preteens was strongly related to experimentation but not to susceptibility. In cross-sectional analyses parental depressed mood was related to children's experimentation, but in longitudinal analyses parental depressed mood at baseline did not differentiate children who experimented from those who did not. Although parental smoking was strongly related to experimentation, it was not related to susceptibility either cross-sectionally or longitudinally. Depressed mood among preteens and parents appeared to be more strongly related to children's smoking behaviors than to their intentions to smoke.

Enhancing adherence to prevent depression relapse in primary care.

We performed a randomized trial to prevent depression relapse in primary care by evaluating intervention effects on medication attitudes and self-management of depression. Three hundred and eighty six primary care patients at high risk for recurrent depression were randomized to receive a 12-month intervention. Interviews at baseline, 3, 6, 9, and 12-months assessed attitudes about medication, confidence in managing side effects, and depression self-management. This depression relapse prevention program significantly increased: 1) favorable attitudes toward antidepressant medication [Beta =.26, 95% C.I. = (.18,.33)]; 2) self-confidence in managing medication side effects [Beta =.53, 95% C.I. = (.15,.91)]; 3) depressive symptom monitoring [O.R. = 4.08, 95% C.I. = (2.80, 5.94)]; 4) checking for early warning signs [O.R. = 3.27, 95% C.I. = (2.32, 4.61)]; and, 5) planful coping [O.R. = 2.01, 95% C.I. = (1.49, 2.72)]. Significant predictors of adherence to long-term pharmacotherapy were: favorable attitudes toward antidepressant treatment [OR = 2.20, 95% CI = (1.50, 3.22)], and increased confidence in managing medication side effects [OR = 1.10, 95% CI = (1.04, 1.68)]. Among primary care patients at high risk for depression relapse, enhanced attitudes towards antidepressant medicines and higher confidence in managing side effects were key factors associated with greater adherence to maintenance pharmacotherapy.
