High rates of sustained smoking cessation in women hospitalized with cardiovascular disease: the Women's Initiative for Nonsmoking (WINS).

BACKGROUND: Although men hospitalized with cardiovascular disease (CVD) show high smoking-cessation rates, similar data for women are lacking. We tested the efficacy of smoking-cessation intervention in women hospitalized for CVD. METHODS AND RESULTS: In this randomized controlled trial conducted from 1996 to 2001, 277 women diagnosed with CVD (mean age 61+/-10 years) were randomly assigned within 1 of 12 San Francisco Bay Area hospitals to a usual-care group (UG; n=135) or intervention group (IG; n=142). Baseline histories were obtained, and interviews to ascertain self-reported smoking status occurred at 6, 12, 24, and 30 months after hospitalization. The UG received strong physician's advice, a self-help pamphlet, and a list of community resources. The IG received strong physician's advice and a nurse-managed cognitive behavioral relapse-prevention intervention at bedside, with telephone contact at intervals after discharge. The groups were similar demographically and had smoked cigarettes for a median of 38 (IG) or 40 (UG) years. Time to resumption of continuous smoking was assessed by Kaplan-Meier analysis, and risk differences between groups were determined. Time smoke-free was significantly greater for the IG than the UG (P=0.038). Point prevalence for nonsmoking at the interviews was somewhat greater for the IG than the UG (P>0.15 at all times). CONCLUSIONS: Cognitive behavioral intervention resulted in longer average times to resumption of smoking, but in these 2 groups of older women with limited social and financial resources, long-term success rates were similar. Systematic identification of smokers and even the brief intervention afforded the UG yielded a high smoking-cessation rate over time.

Women's initiative for nonsmoking (WINS) IV: description of 277 women smokers hospitalized with cardiovascular disease.

OBJECTIVES: This article describes the demographic, psychosocial, and medical characteristics and smoking patterns of women hospitalized with cardiovascular disease (CVD) enrolled in the Women's Initiative for Nonsmoking (WINS) trial. DESIGN: Study design is a randomized clinical trial with cross-sectional baseline data. SETTING: Women enrolled during a 27-month period from 10 hospitals in the San Francisco Bay Area. PARTICIPANTS: Subjects included 277 women. RESULTS: The women's ages ranged from 33 to 86 years, with a mean age of 60.7 (+/-10) years. Most (51%) were college graduates, had attended some college or had postgraduate degrees; 40% were married; 76% were white. Median income was between 30,000 dollars and 35,000, but 27% of the women had incomes less than 15,000 dollars per year. The women smoked a median of 20 cigarettes per day (range, 1-90). Median age when women began smoking was 18.6 years; average number of years smoked was 40; and 78% had made more than 2 previous attempts to quit. On a 10-point scale, 71% of the women rated their confidence to quit smoking (self-efficacy) as 5 or greater. According to the Burnam Depression Screener, 56.7% were depressed. CONCLUSIONS: This is the largest study describing the smoking patterns of women hospitalized with CVD. These women were older, white, had smoked for many years, were moderately to highly addicted to tobacco, had few financial resources, and a large proportion were depressed. These important psychosocial factors need to be taken into account when planning smoking cessation interventions for women with CVD.
