Filter by:This project will generate knowledge about the effectiveness of Enhanced Chronic Care, an intervention designed to enhance treatment use and smoking abstinence in Veterans who are initially unwilling to quit. Enhanced Chronic Care provides ongoing motivational interventions and interpersonal support designed to promote readiness to quit smoking. Enhanced Chronic Care will be compared with Standard Care (brief advice to quit once per year) on criteria that are of great clinical and public health importance: use of cessation treatment and smoking abstinence. It is expected that Enhanced Chronic Care will increase treatment use and smoking abstinence relative to Standard Care.
The overall goal of this study is to determine if switching to very low nicotine content cigarettes changes the function of brain circuitry involved in incentive salience and executive control among dependent smokers.
Objectives. To evaluate the effectiveness and cost effectiveness of clinical practice guide based intervention with two face-to-face visits and e-mail tracking compared to brief advice to obtain continued smoking abstinence at 6 and 12 months after intervention. Methodology. simple randomized controlled multicentric trial. All smokers (N=1064) aged 18 or older that attend by any reason to the primary care center and that have an e-mail account and they checked it at least once a week will be invited to participate. The enrolled participants will be randomly divided into control (N=532) and intervention group (N=532). An intensive intervention, based on the recommendations of the clinical practice guides, that will include six contacts (2 face-to-face and 4 by e-mail) will be applied to the intervention group. Control group will receive brief advice. The main dependent variable will be continued abstinence of tobacco consumption at six and twelve months after the beginning of the intervention which will be validated by and a carbon monoxide breathe analysis measured by a cooximeter in standard conditions. Secondary variables will include: stage change on the quitting smoking process and evaluation of the effectiveness on the reduction of the number of smoked cigarettes at six and twelve months after intervention. A descriptive analysis of all variables will be done. A multivariate analysis will be undertaken to assess differences among intervention and control group; logistic regression for dichotomic variables and lineal regression for continuous variables.
This study aims to evaluate, in a randomized controlled trial, tobacco treatments of varying intensities for smokers hospitalized on acute psychiatric inpatient units.
To test if smokeless tobacco is more effective than nicotine buccal tablets in smoking cessation compared with a control group with low dose nicotine patches. Also retreatment will be tested with smokeless tobacco every 6 months in failures for 1½ year. Adherence to the program will be enhanced by assessment of cholesterol, blood pressure, lung function and body weight every 6 months for 2 years.
