Filter by:Smoking causes 90% of all lung cancer deaths among men and 80% of lung cancer deaths in women. Surgery is a great opportunity to help patients quit smoking. Smokers are at increased risk for heart, lung, and wound complications around the time of surgery. Even a brief abstinence from smoking can produce benefits. Surgery can also motivate smokers to quit spontaneously. If the investigators can take advantage of this great opportunity, they may be able to help many smokers quit using simple means. However, currently most smokers continue to smoke cigarette on the morning before surgery, as shown by the measurement of exhaled carbon monoxide (CO) on the morning of surgery. CO is one of the many poisons in cigarette smoke. It only stays in the body for a few hours. By asking smokers to blow into a small machine, the investigators can test the CO level in the smokers' body and thus know if they have just smoked within the past few hours. The goal of this study is to determine the role of carbon monoxide monitoring as a means to decrease cigarette smoking before surgery. The investigators will identify a group of smokers who are scheduled for surgery and invite them to participate. One or two days before surgery, half of the patients will receive a brief advice about quit smoking. The other half of patients will be told that their CO will be checked before surgery, in addition to the brief advice. On the morning of surgery, the investigators will then check their CO level to determine if they have followed the advice. In order to have a better understanding about the factors influencing patients' intent to quit smoking, the investigators will ask all study participants to fill out a questionnaire. The questionnaire is constructed according to behavioral theories which provide good framework for studying people's intent and behavior. If the investigators are successful, they will determine how much of an impact the message of CO testing has on smoking before surgery. The investigators will also gain insights into facilitators and barriers to smoking cessation around the time of surgery. The brief intervention evaluated in this study has potential to be disseminated and to promote the long term health of surgical patients.
The aim of this study is to compare exposure to tobacco smoke toxins in individuals who smoke both cigarettes and Hookah pipes. Sixteen subjects will be hospitalized on the research ward for two visits of 4 days each. At one visit they will smoke their usual cigarettes in approximately normal frequency, and at the other visit they will smoke Hookah at least twice per day. The order of the visits will be randomized. On the fourth day of each visit (when nicotine, carbon monoxide (CO), and some carcinogen levels will be in a steady state condition), circadian blood and urine and expired air samples will be collected.
The current study tested the effectiveness of four potentially important tailoring factors (decisional framework, self-efficacy, navigation autonomy, and proactive outreach) in the context of an online motivational intervention for smoking cessation. A fifth factor was originally planned by dropped during intervention development due to confounds with the other planned factors. Information learned from this study will inform how to best design an online interventions for smoking cessation. Participants were recruited from a large, regional U.S. health plan. Using a full factorial design to screen for important main effects and 2-way interactions, participants were randomized to receive one of 16 different experimental factor combinations and followed for one year to assess program impact on smokers' use of empirically-validated cessation treatment and abstinence.
The major purpose of this exploratory developmental study will be to develop a patient-centered and feasible protocol for communicating genetic data as it relates to drug efficacy for smoking cessation inpatients receiving medication that is matched to individual genotypes associated with increased efficacy for bupropion or nicotine replacement therapy.
The purpose of this study is to evaluate Fax to Quit (F2Q) - a strategy that links state quitlines to health care delivery systems. FQ capitalizes upon the healthcare visit as an opportunity for intervention, consistent with the finding that approximately 70% of smokers visit a primary care physician each year. Successful integration of quitlines into healthcare delivery will transform regular healthcare visits into easily implemented, cost-beneficial avenues via which smokers all across America will be routinely inducted into effective cessation intervention. F2Q will be evaluated as follows: 1. Does F2Q increase contacts and "quality contacts," between the quitline and patients who smoke and receive health care at a participating clinic? A "quality contact" is defined as a quitline referral that results in the individual enrolling in the quitline counseling services. This aim will be assessed by measuring the rates of quitline referrals in 49 clinics before and after F2Q has been implemented. 2. Are contact rates and enrollment rates of F2Q increased by "Enhanced Academic Detailing" at clinic sites (with enhanced academic detailing comprising ongoing training/technical assistance as well as performance feedback)? 3. What are the features of the Fax to Quit (F2Q) and Fax to Quit plus Enhanced Academic Detailing (F2Q + EAD) interventions that key clinic personnel found helpful and easy to implement, as well as features that were unhelpful and difficult? This information will be gathered in qualitative assessments that also will identify clinic strategies and organizational features that facilitated successful implementation. 4. What are the incremental costs of instating and sustaining F2Q and F2Q + EAD and how do these costs compare to other quitline promotional strategies (e.g., paid media, medication give-away programs)?
The aim of the present study is to assess if a personal care program of smokers hospitalised for acute coronary syndrome can change the smoking habits as compared with similar patients in conventional care program at 6 months. The program includes a cognitive-behavioural approach associated with a nicotine replacement treatment presented as an obligatory non optional treatment. Patients are men and women of less than 70 years old hospitalised for acute coronary syndrome. Major exclusion criteria is the presence of another dependence. The program includes a cognitive-behavioural approach based on the specific technique of "exposure" and the prescription of nicotine patch considered as other usual cardiologic treatments for at least 6 months. The end point is the smoking habits at 6 months classified as: no smoking confirmed by CO measurement, smoking or doubtful (declaration of no smoking by the patient but a CO level > 10 ppm). 72 patients in each group will be included in 2 majors sites.
A multi-center, randomized, double-blind, placebo-controlled, 4-arm clinical study to evaluate efficacy and safety of nicotine lozenge (2mg and 4mg) in smoking cessation in adult cigarette smokers who are motivated to quit smoking. Successful quitters or participants who smoke occasionally will be followed up after week 24 till 12 months.
The goal of this research study is to learn the effectiveness of telephone-based counseling on helping smokers change their smoking patterns.
The final purpose of this study is to determine whether bronchodilation and cigarette smoking in Chronic Obstructive Pulmonary Disease (COPD) patients interact, resulting in an increase of cardiovascular disease. The aim of this part of the study is to demonstrate the basic mechanism: Does increased respiratory function after administration of a bronchodilator in patients with COPD lead to elevated pulmonary retention of the harmful compounds in inhaled cigarette smoke and to short-term biological effects associated with cardiovascular disease?
The National Health Service (NHS) stop smoking service at the Central Lancashire NHS Trust serves a diverse population of smokers, with a very good quit rate and high standards. However, clinical experience predicts that some clients are unlikely to succeed through the NHS smoking cessation program. This special population has difficulty quitting for a variety of reasons. Some relapse over the course of the following two years and return repeatedly to the service. Others, for instance those with health problems, may be highly motivated to quit, but unable to resist their cravings. The purpose of this study is to determine if EFT makes a difference in quit rates with the most challenging population of clients.
