A smoking cessation programme for use in general practice 总被引:2,自引:0,他引:2
The effectiveness of a smoking intervention programme based in general practice was evaluated at six months by a randomized controlled trial. In the programme, general practitioners achieved a 33% success rate compared with 3% in a control group. Reported abstinence was checked by blood tests for cotinine, carboxyhaemoglobin and thiocyanate. The majority of patients considered that their chances of success were greater if a doctor administered the programme, and that having the results of lung function and blood tests explained in relation to the risks of cardiovascular and respiratory diseases constituted a strong incentive to stop smoking. Two cases illustrating a successful and a failed outcome of the programme are described. If one quarter of general practitioners in Australia adopted this programme in their practice, approximately 150,000 new abstainers could be expected each year. 相似文献

Sustained-release bupropion for smoking cessation in African Americans: a randomized controlled trial 总被引:7,自引:0,他引:7
Context African Americans disproportionately experience greater smoking attributable morbidity and mortality. Few clinical trials for smoking cessation in African Americans have been conducted, despite a different profile of both smoking and quitting patterns. Objective To compare a sustained-release form of bupropion hydrochloride (bupropion SR) with placebo for smoking cessation among African Americans. Design, Setting, and Participants Randomized, double-blind, placebo-controlled trial conducted from February 11, 1999, to December 8, 2000, of 600 African American adults treated at a community-based health care center. Volunteers, who smoked 10 or more cigarettes per day were recruited by targeted media and health care professionals. Intervention Participants were randomly assigned to receive 150 mg of bupropion SR (n = 300) or placebo (n = 300) twice daily for 7 weeks. Brief motivational counseling was provided in-person at baseline, quit day, weeks 1 and 3, end of treatment (week 6), and by telephone at day 3 and weeks 5 and 7. Main Outcome Measures Biochemically confirmed 7-day point prevalence abstinence at weeks 6 and 26 following quit day. Results Using intention-to-treat procedures, confirmed abstinence rates at the end of 7 weeks of treatment were 36.0% in the bupropion SR group and 19.0% in the placebo group (17.0 percentage point difference; 95% confidence interval, 9.7-24.4; P<.001). At 26 weeks the quit rates were 21.0% in the treatment and 13.7% in the placebo groups (7.3 percentage point difference; 95% confidence interval, 1.0-13.7; P = .02). Those taking bupropion SR experienced a greater mean reduction in depression symptoms at week 6 (2.96 [9.45] vs 1.13 [8.84]) than those taking placebo, and after controlling for continuous abstinence, those taking bupropion SR also gained less weight than those taking placebo. Conclusions Bupropion SR was effective for smoking cessation among African Americans and may be useful in reducing the health disparities associated with smoking. 相似文献

Several smoking intervention studies have been conducted overseas which use a minimal amount of general practitioners' time and are conducted within the constraints of a normal consultation. However, there are no published reports of minimal interventions in Australian general practice. This study reports on 1238 South Australian smokers who were assigned to a non-intervention control group or a group which received firm general practitioner advice to quit smoking plus literature. At one-year follow-up, 7.5% of smokers in the minimal advice group who had quit for six or more months remained non-smokers compared with 3.2% in the control group. If similar analytical procedures had been used in this study as were used in the benchmark study in England in 1979, the quit rate for this study would have been 11.3% in the intervention group, and 4.8% in the control group--a net gain of 6.5%. These results are discussed with regard to widespread implementation in Australian general practice. 相似文献

Tobacco dependence is a chronic relapsing medical illness. Unfortunately more than 1.1 billion people worldwide smoke tobacco. Tobacco consumption rate is very high in India. Providing three minutes counseling by physicians doubles the cessation rate as compared to no intervention. Nicotine replacement products (gums, transdermal patch, nasal spray, inhaler and lozenge), bupropion and varenicline used with counseling by physicians double the cessation rates at one year. There are drugs like buspirone, naltrexone, mecamylamine and silver acetate; some of which either alone or in combination with any of the above drugs may be routinely used in near future for smoking cessation in at least some specific groups of population. The most difficult problem for patients in smoking cessation is withdrawal symptoms. Counseling with continuous support from physician, family members, friends and overall from the society will help in achieving a higher rate of smoking cessation, with the final aim of making ours a tobacco smoke-free world for future generations. 相似文献

Context The 42 nicotinic acetylcholine receptors (nAChRs) are linked to the reinforcing effects of nicotine and maintaining smoking behavior. Varenicline, a novel 42 nAChR partial agonist, may be beneficial for smoking cessation. Objective To assess efficacy and safety of varenicline for smoking cessation compared with sustained-release bupropion (bupropion SR) and placebo. Design, Setting, and Participants Randomized, double-blind, parallel-group, placebo- and active-treatmentcontrolled, phase 3 clinical trial conducted at 19 US centers from June 19, 2003, to April 22, 2005. Participants were 1025 generally healthy smokers (10 cigarettes/d) with fewer than 3 months of smoking abstinence in the past year, 18 to 75 years old, recruited via advertising. Intervention Participants were randomly assigned in a 1:1:1 ratio to receive brief counseling and varenicline titrated to 1 mg twice per day (n = 352), bupropion SR titrated to 150 mg twice per day (n = 329), or placebo (n = 344) orally for 12 weeks, with 40 weeks of nondrug follow-up. Main Outcome Measures Primary outcome was the exhaled carbon monoxideconfirmed 4-week rate of continuous abstinence from smoking for weeks 9 through 12. A secondary outcome was the continuous abstinence rate for weeks 9 through 24 and weeks 9 through 52. Results For weeks 9 through 12, the 4-week continuous abstinence rates were 44.0% for varenicline vs 17.7% for placebo (odds ratio [OR], 3.85; 95% confidence interval [CI], 2.70-5.50; P<.001) and vs 29.5% for bupropion SR (OR, 1.93; 95% CI, 1.40-2.68; P<.001). Bupropion SR was also significantly more efficacious than placebo (OR, 2.00; 95% CI, 1.38-2.89; P<.001). For weeks 9 through 52, the continuous abstinence rates were 21.9% for varenicline vs 8.4% for placebo (OR, 3.09; 95% CI, 1.95-4.91; P<.001) and vs 16.1% for bupropion SR (OR, 1.46; 95% CI, 0.99-2.17; P = .057). Varenicline reduced craving and withdrawal and, for those who smoked while receiving study drug, smoking satisfaction. No sex differences in efficacy for varenicline were observed. Varenicline was safe and generally well tolerated, with study drug discontinuation rates similar to those for placebo. The most common adverse events for participants receiving active-drug treatment were nausea (98 participants receiving varenicline [28.1%]) and insomnia (72 receiving bupropion SR [21.9%]). Conclusion Varenicline was significantly more efficacious than placebo for smoking cessation at all time points and significantly more efficacious than bupropion SR at the end of 12 weeks of drug treatment and at 24 weeks.

A relationship between cigarette smoking and major depressive disorder was suggested in previous work involving nonrandomly selected samples. We conducted a test of this association, employing population-based data (n = 3213) collected between 1980 and 1983 in the St Louis Epidemiologic Catchment Area Survey of the National Institute of Mental Health. A history of regular smoking was observed more frequently among individuals who had experienced major depressive disorder at some time in their lives than among individuals who had never experienced major depression or among individuals with no psychiatric diagnosis. Smokers with major depression were also less successful at their attempts to quit than were either of the comparison groups. Gender differences in rates of smoking and of smoking cessation observed in the larger population were not evident among the depressed group. Furthermore, the association between cigarette smoking and major depression was not ubiquitous across all psychiatric diagnoses. Other data are cited indicating that when individuals with a history of depression stop smoking, depressive symptoms and, in some cases, serious major depression may ensue. 相似文献

Context Varenicline, a partial agonist at the 42 nicotinic acetylcholine receptor, has the potential to aid smoking cessation by relieving nicotine withdrawal symptoms and reducing the rewarding properties of nicotine. Objective To determine the efficacy and safety of varenicline for smoking cessation compared with placebo or sustained-release bupropion (bupropion SR). Design, Setting, and Participants A randomized, double-blind, placebo-controlled trial conducted between June 2003 and March 2005 at 14 research centers with a 12-week treatment period and follow-up of smoking status to week 52. Of 1413 adult smokers who volunteered for the study, 1027 were enrolled; 65% of randomized participants completed the study. Intervention Varenicline titrated to 1 mg twice daily (n = 344) or bupropion SR titrated to 150 mg twice daily (n = 342) or placebo (n = 341) for 12 weeks, plus weekly brief smoking cessation counseling. Main Outcome Measures Continuous abstinence from smoking during the last 4 weeks of treatment (weeks 9-12; primary end point) and through the follow-up period (weeks 9-24 and 9-52). Results During the last 4 weeks of treatment (weeks 9-12), 43.9% of participants in the varenicline group were continuously abstinent from smoking compared with 17.6% in the placebo group (odds ratio [OR], 3.85; 95% confidence interval [CI], 2.69-5.50; P<.001) and 29.8% in the bupropion SR group (OR, 1.90; 95% CI, 1.38-2.62; P<.001). For weeks 9 through 24, 29.7% of participants in the varenicline group were continuously abstinent compared with 13.2% in the placebo group (OR, 2.83; 95% CI, 1.91-4.19; P<.001) and 20.2% in the bupropion group (OR, 1.69; 95% CI, 1.19-2.42; P = .003). For weeks 9 through 52, 23% of participants in the varenicline group were continuously abstinent compared with 10.3% in the placebo group (OR, 2.66; 95% CI, 1.72-4.11; P<.001) and 14.6% in the bupropion SR group (OR, 1.77; 95% CI, 1.19-2.63; P = .004). Treatment was discontinued due to adverse events by 10.5% of participants in the varenicline group, 12.6% in the bupropion SR group, and 7.3% in the placebo group. The most common adverse event with varenicline was nausea, which occurred in 101 participants (29.4%). Conclusions Varenicline is an efficacious, safe, and well-tolerated smoking cessation pharmacotherapy. Varenicline's short-term and long-term efficacy exceeded that of both placebo and bupropion SR.

The treatment preferences of 109 general practitioners (GPs) for childhood asthma were determined. Availability and adherence to clinical practice guidelines (CPG) for the treatment of childhood asthma was also assessed. Ninety eight (90%), 60 (55%) and 33 (30%) GPs considered nocturnal symptoms > 2 times/week, exercise induced wheeze and cough respectively as indications for preventer therapy. An oral preparation was preferred for relief medication [72 (66%) for 2-5 years, 60 (55%) for > 5 years]. An inhaled preparation was however preferred for preventer medication [60 (55%) for 2-5 years, 85 (78%) for > 5 years]. The oral form was more likely prescribed for asthmatic children 2-5 years (p < 0.001). Corticosteroids and ketotifen were the commonest inhaled and oral preventer treatment prescribed respectively. Only 36(33%) GPs have a CPG copy for reference. Children with asthma symptoms that require preventer therapy may not always be identified in general practice. The oral route remains important for asthma medication especially in young children. The accessibility to the CPG among GPs is disappointing. 相似文献

The pharmacotherapy of smoking cessation 总被引:1,自引:0,他引:1
1. The great majority of smokers are chronically dependent on tobacco. This dependence arises from the rituals and sensory associations of smoking that are reinforced, within seconds, by a rapid burst of nicotine from the cigarette. 2. All forms of nicotine replacement therapy (NRT) -- gum, patches and inhaler -- and bupropion are safe and effective for increasing smoking cessation rates in the short and long terms. 3. Other than those who are minimally dependent, all patients willing to quit should be offered one of these therapies unless contraindications exist. The effectiveness of drug treatments is multiplied when associated with effective counselling or behavioural treatments. 4. While NRT is not recommended during pregnancy or in patients with cardiac disease, if the alternative is smoking NRT is almost certainly safe. 5. Combination NRT (more than one therapy) may be indicated in patients who have failed monotherapy in association with withdrawal symptoms. 6. There are some specific contraindications to the use of bupropion. Its subsidised availability should not influence prescribers to ignore these. 相似文献
