We tested the effectiveness of an individually delivered behavioral multicomponent smoking intervention (SI) against offering advice only (AO) to 267 patients after coronary arteriography. After 6 months, 51% of AO patients and 62% of SI patients reported abstinence. Validated rates were 34% and 45% for AO and SI patients, respectively. Logistic regression analyses, controlling for severity of illness, stage of change, and self-efficacy, among other variables, showed that, at 6 months, the SI had the most effect for patients with more severe coronary artery disease (CAD) who had been admitted with a myocardial infarction (95% confidence interval = 2.05, 124.85). At 12 months, only severity of disease mediated SI effects (95% confidence interval = 3.10, 58.00). Similar results were seen for cotinine-validated cessation. This study confirms the effectiveness of individually administered SI for more seriously ill patients with CAD and raises questions as to how to better intervene with those individuals with less severe disease. Smoking cessation after myocardial infarction (MI) has been associated with a 50% reduction in mortality but in-hospital smoking cessation interventions are rarely part of routine clinical practice.
                One hundred cigarette smokers consecutively admitted during 1996 with MI were assigned to minimal care or to a hospital-based smoking cessation program. Intervention consisted of bedside cessation counseling followed by seven telephone calls over the 6 months following discharge. Primary outcomes were abstinence rates measured at 6 months and 1 year post-discharge.
                At follow-up, 43 and 34% of participants in minimal care and 67 and 55% of participants in intervention were abstinent at 6 and 12 months. respectively (P<0.05). Abstinence rates were calculated assuming that participants lost to attrition were smokers at follow-up. Intervention and self-efficacy were independent predictors of smoking status at follow-up. Low self-efficacy combined with no intervention resulted in a 93% relapse rate by 1 year (P<0.01).
                A hospital-based smoking cessation program consisting of inpatient counseling and telephone follow-up substantially increases smoking abstinence 1 year after discharge in patients post-MI. Patients with low self-efficacy are almost certain to relapse without intervention. Such smoking cessation programs should be part of the management of patients with MI.

                Randomised controlled trial.
                Cardiac ward of a general hospital, Norway.
                240 smokers aged under 76 years admitted for myocardial infarction, unstable angina, or cardiac bypass surgery. 118 were randomly assigned to the intervention and 122 to usual care (control group).
                The intervention was based on a booklet and focused on fear arousal and prevention of relapses. The intervention was delivered by cardiac nurses without special training. The intervention was initiated in hospital, and the participants were contacted regularly for at least five months.
                Smoking cessation rates at 12 months determined by self report and biochemical verification.
                12 months after admission to hospital, 57% (n = 57/100) of patients in the intervention group and 37% (n = 44/118) in the control group had quit smoking (absolute risk reduction 20%, 95% confidence interval 6% to 33%). The number needed to treat to get one additional person who would quit was 5 (95% confidence interval, 3 to 16). Assuming all dropouts relapsed at 12 months, the smoking cessation rates were 50% in the intervention group and 37% in the control group (absolute risk reduction 13%, 0% to 26%).
                A smoking cessation programme delivered by cardiac nurses without special training, significantly reduced smoking rates in patients 12 months after admission to hospital for coronary heart disease. The hypothesis that 6 months after acute myocardial infarction, adoption of secondary prevention activities would be higher, quality of life better, and blood cholesterol lower in patients randomly allocated to a mail-out intervention program than in those receiving usual care was tested. Patients were aged < 70 years, admitted to hospitals in and around Newcastle, Australia with a suspected heart attack and discharged alive from the hospital. Cluster randomization, based on the patient's family practitioner, was used to allocate consenting patients to an intervention or usual care group. A low-cost mail-out program was designed to help patients reduce dietary fat, obtain regular exercise by walking and (for smokers only) to quit smoking. Supplementary telephone contact was also used. In addition, a letter was sent to the family doctor regarding the benefit of aspirin and beta blockers for secondary prevention. Of eligible patients, 71% participated, and 79% of the 213 intervention subjects and 87% of the 237 usual care ones returned a 6-month follow-up questionnaire. Self-reported fat intake was significantly lower, an "emotional" score obtained from a quality-of-life questionnaire was significantly higher in the intervention than in the usual care group, and "physical" and "social" scores for quality of life were slightly higher. Blood cholesterol level and other variables were not different between the groups at 6 months. Simple low-cost programs providing support and advice on lifestyle change may be beneficial, particularly in improving patients' perceived quality of life. A health education and counselling programme was offered to myocardial infarction patients during and after hospitalization. A randomized pre-test-post-test control group design was used to evaluate the effects of the experimental intervention. During hospitalization the intervention consisted of two individual counselling sessions and two group health education sessions focusing on medication, healthy habits, anxiety and depression. On completion of these sessions, weekly telephone calls were made to patients for a period of six weeks after discharge from hospital. The intervention was offered to 30 myocardial infarction patients and their partners (the experimental group) in addition to standard medical care. Thirty control patients received standard medical care only. Two months after myocardial infarction, patients in the experimental condition reported a significantly greater increase in physical activity, and a significantly greater decrease in unhealthy eating habits. No effects were found regarding smoking cessation, anxiety and depression. Twelve months after discharge from hospital patients in the experimental condition reported a significantly greater decrease in unhealthy eating habits. No effects were found regarding smoking cessation, physical activity, anxiety and depression. In addition, two months after myocardial infarction, it was found that patients whose partners participated in the health education sessions showed a significantly greater decrease in smoking and unhealthy eating habits and a significantly greater increase in physical activity than patients with no partner participating. Twelve months after discharge the only significant result favouring the patients whose partner participated in the health education sessions concerned smoking cessation. Smoking cessation is an important goal for smokers with coronary artery disease (CAD) because it reduces cardiac morbidity and mortality. Effective interventions for cigarette smokers with CAD exist, but they often are considered to be intensive and expensive. Stepped-care interventions have been proposed as a promising way to allocate smoking cessation treatments in a cost-effective manner. Stepped care refers to the practice of initiating treatment with low-intensity intervention and then exposing treatment failures to successively more intense interventions.
                To address the efficacy of this approach, 254 cigarette smokers hospitalized with CAD were provided a brief cessation intervention. The participants then were assigned randomly to either a more intensive stepped-care treatment (counseling and nicotine patch therapy) or no additional treatment. Outcomes were point-prevalent abstinence measured 3 months and 1 year after hospital discharge.
                Stepped-care treatment increased smoking cessation rates from 42% to 53% during a 3-month follow-up period (P =.05), but showed little effect at the 1-year follow-up assessment, as evidenced by a cessation rate for the minimal intervention group of 36% versus 39% for the stepped-care group (P =.36).
                A stepped-care approach to smoking cessation increased short-but not long-term point-prevalent abstinence in patients with CAD. For improvement of long-term effectiveness, refinement of the timing and content of stepped-care interventions needs to occur. nan In a trial to evaluate the effectiveness of a nurse-directed intervention designed to help patients decrease dietary intake of fat, quit or decrease smoking, and increase exercise, 138 women who underwent coronary artery bypass surgery were randomized to receive special intervention (SI) or usual care (UC). The SI group received a behavioral program based on self-efficacy theory in the home 2 weeks after discharge with regular follow-up. The UC group received routine medical care. Risk factors and lifestyle behaviors were measured at baseline and 1 year after surgery in 116 (84%) women (SI = 59, UC = 57). The SI group decreased their total fat intake from a mean of 38% of calories at baseline to 35% at 1 year, while the UC group increased it from 36% to 38%. The prevalence of smoking decreased from 24% at baseline to 8% at 1 year in the SI group and from 19% to 14% in the UC group. At follow-up, the quit rate in those smoking at baseline was 64% in the SI group, with no new smokers, and 55% in the UC group, with three new smokers. Both groups reported improvement in exercise, with the proportion of women reporting participation in some form of regular exercise slightly higher in the SI group than in the UC group, 54% and 51%, respectively. The aim of this study was to evaluate the efficacy of an structured intervention based on a medical advice versus to the ordinary anti-tobacco advice in patients with miocardial infarction who are attended in an Intensive Care Unit (ICU).
                90 patients were randomly selected to receive either the specific intervention (intervention group) or the ordinary advice (control group). The medical advice was given during the ICU hospitalization and during the second, the third and the fourth week. One year later the smoking habit was evaluated.
                After one year 26 patients of the intervention group and 31 patients of the control group had stopped smoking (RR = 0.88 [CI 95% RR] 0.57 to 1.37).
                The percentage of patients who stop smoking after a miocardial infarction is high. The structured medical counselling was not effective to reduce the number of smokers at one year. To examine the ability of a secondary prevention programme to improve the lifestyle in myocardial infarction patients aged 50-70 years.
                Habitual physical activity, food habits, and smoking habits were assessed from questionnaires at admission to hospital and at the one year follow up. Initially, all patients were invited to join an exercise programme and were informed about cardiovascular risk factors. Four weeks after discharge from the hospital, 87 patients were randomised to follow up at the coronary prevention unit by a special trained nurse (the intervention group), and 81 to follow up by their general practitioners (the usual care group). After randomisation, the intervention group was educated about the effects of smoking cessation, dietary management, and regular physical activity. The intervention group also participated in a physical training programme two to three times weekly for 10-12 weeks.
                89% of the patients referred to the intervention group improved their food habits compared with 62% of the patients referred to the usual care group (P = 0.008). Furthermore, 50% of the smokers referred to the intervention group stopped smoking compared to 29% in the usual care group (P = 0.09). Changes in physical activity did not differ between the groups.
                This secondary prevention programme based on a nurse rehabilitator was successful in improving food habits in patients with acute myocardial infarction. Initiating the smoking cessation programme during the hospital stay followed by repeated counselling during follow up might have improved the results. The exercise programme had no advantage in supporting physical activity compared to usual care. To evaluate a smoking cessation intervention that can be routinely delivered to smokers admitted with cardiac problems.
                Randomised controlled trial of usual care compared with intervention delivered on hospital wards by cardiac rehabilitation nurses.

                540 smokers admitted to hospital after myocardial infarction or for cardiac bypass surgery who expressed interest in stopping smoking.
                Brief verbal advice and standard booklet (usual care). Intervention lasting 20-30 minutes including carbon monoxide reading, special booklet, quiz, contact with other people giving up, declaration of commitment to give up, sticker in patient's notes (intervention group).
                Continuous abstinence at six weeks and 12 months determined by self report and by biochemical validation at these end points. Feasibility of the intervention and delivery of its components.
                After six weeks 151 (59%) and 159 (60%) patients remained abstinent in the control and intervention group, respectively (P=0.84). After 12 months the figures were 102 (41%) and 94 (37%) (P=0.40). Recruitment was slow, and delivery of the intervention was inconsistent, raising concerns about the feasibility of the intervention within routine care. Patients who received the declaration of commitment component were almost twice as likely to remain abstinent than those who did not receive it (P<0.01). Low dependence on tobacco and high motivation to give up were the main independent predictors of positive outcome. Patients who had had bypass surgery were over twice as likely to return to smoking as patients who had had a myocardial infarction.
                Single session interventions delivered within routine care may have insufficient power to influence highly dependent smokers. To determine the effect of a nurse-managed intervention for smoking cessation in patients who have had a myocardial infarction.
                Randomized, with a 6-month treatment period and a 6-month follow-up.
                Kaiser Foundation hospitals in Redwood City, Santa Clara, Hayward, and San Jose, California.
                Sequential sample of 173 patients, 70 years of age or younger, who were smoking before hospitalization for acute myocardial infarction. Eighty-six patients were randomly assigned to the intervention and 87 to usual care; 130 patients (75%) completed the study and were available for follow-up.
                Nurse-managed and focused on preventing relapse to smoking, the intervention was initiated in the hospital and maintained thereafter primarily through telephone contact. Patients were given an 18-page manual that emphasized how to identify and cope with high-risk situations for smoking relapse.
                One year after myocardial infarction, the smoking cessation rate, verified biochemically, was 71% in the intervention group compared with 45% in the usual care group, a 26% difference (95% CI, 9.5% to 42.6%). Assuming that all surviving patients lost to follow-up were smoking, the 12-month smoking cessation rate was 61% in the intervention group compared with 32% in the usual care group, a 29% difference (95% CI, 14.5% to 43.5%). Patients who either resumed smoking within 3 weeks after infarction or expressed little intention of stopping in the hospital were unlikely to have stopped by 12 months.
                A nurse-managed smoking cessation intervention largely conducted by telephone, initiated in the hospital, and focused on relapse prevention can significantly reduce smoking rates at 12 months in patients who have had a myocardial infarction. To test the efficacy of a smoking cessation program for inpatients recovering from coronary artery bypass graft surgery and to identify predictors of cessation.
                Randomized, controlled clinical trial.
                Postoperative cardiac surgery unit of a large teaching hospital.
                Patients scheduled for coronary artery bypass surgery by participating surgeons between 1 July 1986 and 1 July 1987 who had smoked 1 or more packs of cigarettes in the 6 months before admission. Of 120 eligible patients, 93 enrolled and 87 were discharged alive. All survivors were followed for at least 1 year; 94% were followed for a median of 5.5 years.
                A three-session, nurse-delivered behavior modification program using a videotape and face-to-face counseling was compared to usual care.
                Smoking status was assessed six times in the year after surgery and 5.5 years after surgery. Self-reported nonsmoking was validated by saliva cotinine assay 1 and 5.5 years after surgery.
                No statistically significant differences were found between control (n = 43) and intervention (n = 44) groups at baseline. One and 5.5 years after hospital discharge, validated continuous nonsmoking rates were identical in intervention and control groups (51% at 1 year; 44% at 5.5 years). Multiple logistic regression identified four factors that were independently associated with nonsmoking for 1 year: fewer than 3 previous attempts to quit (odds ratio, 7.4; 95% Cl, 1.9 to 29.1); more than 1 week of preoperative nonsmoking (odds ratio, 10.0; Cl, 2.0 to 50.2); definite intention to quit smoking (odds ratio, 12.0; Cl, 2.6 to 55.1); and no difficulty not smoking in the hospital (odds ratio, 9.6; Cl, 1.8 to 52.2). Nonsmoking for 5.5 years was independently associated with two of these factors: fewer than three previous attempts to quit and intention to quit smoking after surgery. Cessation was not related to demographic factors, daily cigarette consumption, disease severity, hospital course, social support, or beliefs and attitudes.
                Even without specific intervention, nearly one half of smokers quit for 5 years after coronary artery bypass surgery. A short inpatient education program did not increase this rate. Future efforts should target the time after discharge and focus on increasing motivation in patients who have repeatedly failed to quit. To evaluate the efficacy of a physician-directed, nurse-managed, home-based case-management system for coronary risk factor modification.
                Randomized clinical trial in which patients received a special intervention (n = 293) or usual medical care (n = 292) during the first year after acute myocardial infarction.
                5 Kaiser Permanente Medical Centers in the San Francisco Bay area.
                585 men and women aged 70 years or younger who were hospitalized for acute myocardial infarction.
                In the hospital, specially trained nurses initiated interventions for smoking cessation, exercise training, and diet-drug therapy for hyperlipidemia. Intervention after discharge was implemented primarily by telephone and mail contact with patients in their homes. All medically eligible patients received exercise training; all smokers received the smoking cessation intervention; and all patients received dietary counseling and, if needed, lipid-lowering drug therapy.
                Smoking prevalence and plasma low-density lipoprotein cholesterol (LDL) concentrations were measured 2 months after infarction, and functional capacity was measured 6 months after infarction.
                In the special intervention and usual care groups, the cotinine-confirmed smoking cessation rates were 70% and 53% (P = 0.03), plasma LDL cholesterol levels were 2.77 +/- 0.69 mmol/L and 3.41 +/- 0.90 mmol/L (107 +/- 30 mg/dL and 132 +/- 30 mg/dL) (P = 0.001), and functional capacities were 9.3 +/- 2.4 METS and 8.4 +/- 2.5 METS (P = 0.001), respectively.
                In a large health maintenance organization, a case-management system was considerably more effective than usual medical care for modification of coronary risk factors after myocardial infarction.
Psychosocial smoking cessation interventions are effective in promoting abstinence at 1 year, provided they are of sufficient duration. Further studies, with longer follow-up, should compare different psychosocial intervention strategies, or the addition of a psychosocial intervention strategy to pharmacological therapy (e.g. nicotine replacement therapy) compared with pharmacological treatment alone.
