Promoting tobacco cessation in primary care practice

Design and baseline characteristics from the KAN-QUIT disease management intervention for rural smokers in primary care

OBJECTIVE

To describe the design, implementation, baseline data, and feasibility of establishing a disease management program for smoking cessation in rural primary care.

METHOD

The study is a randomized clinical trial evaluating a disease management program for smoking cessation. The intervention combined pharmacotherapy, telephone counseling, and physician feedback, and repeated intervention over two years. The program began in 2004 and was implemented in 50 primary care clinics across the State of Kansas.

RESULTS

Of eligible patients, 73% were interested in study participation. 750 enrolled participants were predominantly Caucasian, female, employed, and averaged 47.2 years of age (SD=13.1). In addition to smoking, 427 (57%) had at least one additional major risk factor for cardiovascular disease (diabetes, hypertension, high cholesterol, heart disease or stroke). Participants smoked on average 23.7 (SD=10.4) cigarettes per day, were contemplating (61%) or preparing to quit (30%), were highly motivated and confident of their ability to quit smoking, and reported seeing their physicians multiple times in the past twelve months (Median=3.50; Mean=5.48; SD=6.58).

CONCLUSION

Initial findings demonstrate the willingness of patients to enroll in a two-year disease management program to address nicotine dependence, even among patients not ready to make a quit attempt. These findings support the feasibility of identifying and enrolling rural smokers within the primary care setting.

A survey of tobacco-related knowledge, attitudes and behaviours of primary care providers in Mississippi

RATIONALE

Relative to other regions in the USA, Mississippi has a high prevalence of tobacco use and tobacco-related disease. This study assessed the tobacco-related knowledge, attitudes and intervention behaviours of family doctors, dentists and nurse practitioners in the state of Mississippi.

METHODS

The Provider Attitude Survey, an 85-item measure of tobacco-related knowledge, attitudes and intervention behaviours was mailed to all members of Mississippi's Family Medicine, Dentistry and Nurse Practitioner professional organizations (N=2043).

RESULTS

Over one-third (n=802, 39.2%) of eligible providers responded. Just 24.3% had received training in tobacco cessation and 33.7% were aware of the Public Health Service clinical practice guideline. Over 90% indicated that it was their role to prevent tobacco use; felt rewarded when they helped patients quit; and were bothered and upset by the health effects of tobacco. Doctors assisted more patients than nurses or dentists. Doctors and nurses reported more self-efficacy, motivation and preparedness for treating tobacco use than dentists. Providers with training performed more interventions and reported more self-efficacy, preparedness and fewer barriers than those without training. Training was associated with greater increases in self-efficacy, preparedness and intervention behaviours for dentists than for the other groups.

CONCLUSIONS

Despite a high prevalence of tobacco use and tobacco-related disease in Mississippi, primary care providers in Mississippi provide tobacco cessation interventions at an unacceptably low frequency relative to other regions. Training is likely to increase the frequency of intervention behaviours.

Effect on cessation counseling of documenting smoking status as a routine vital sign: an ACORN study

PURPOSE

Guidelines encourage primary care clinicians to document smoking status when obtaining patients' blood pressure, temperature, and pulse rate (vital signs), but whether this practice promotes cessation counseling is unclear. We examined whether the vital sign intervention influences patient-reported frequency and intensity of tobacco cessation counseling.

METHODS

This study was a cluster-randomized, controlled trial conducted in the Virginia Ambulatory Care Outcomes Research Network (ACORN). At intervention practices, nurses and medical assistants were instructed to assess the tobacco use status of every adult patient and record it with the traditional vital signs. Control practices did not use any systematic tobacco screening or identification system. Outcomes were the proportion of smokers reporting clinician counseling of any kind and the frequency of 2 counseling subcomponents: simple quit advice and more intensive discussion.

RESULTS

A total of 6,729 adult patients (1,149 smokers) at 18 primary care practices completed exit questionnaires during a 6-month comparison period. Among 561 smokers at intervention practices, 61.9% reported receiving any counseling, compared with 53.4% of the 588 smokers at control practices, for a difference of 8.6% (P = .04). The effect was largely restricted to simple advice, which was reported by 59.9% of intervention patients and 51.5% of control patients (P=.04). There was no significant increase in more extensive discussion, with 32.5% and 29.3% of patients at intervention and control practices, respectively, reporting this type of counseling (P=.18).

CONCLUSIONS

The vital sign intervention promotes tobacco counseling at primary care practices through a modest increase in simple advice to quit. When implemented as a stand-alone intervention, it does not appear to increase intensive counseling.

The association between patient-reported receipt of tobacco intervention at a primary care visit and smokers' satisfaction with their health care

U.S. Public Health Service (USPHS) clinical guidelines for tobacco treatment recommend that providers routinely counsel smokers using a five-step algorithm (5A's): ask about tobacco use, advise smokers to quit, assess interest in quitting, assist with treatment, and arrange follow-up. A potential barrier to compliance is providers' concern that addressing smoking might alienate smokers, especially those not ready to quit. A survey was mailed to 1,985 patients seen at one of eight Boston-area primary care practices from January 1 to March 31, 2003, and identified as smokers by chart review. The survey assessed respondents' receipt of the 5A's at their visit and their satisfaction with the provider's tobacco treatment and with their overall health care. We used multivariable logistic regression models to assess the association between satisfaction with care and patient-reported receipt of each 5A step, adjusted for age, sex, education, race, health status, smoking intensity, readiness to quit, and length of relationship with provider. Of 1,160 respondents (58% response rate), 765 reported that they smoked at the time of the visit. They reported high levels of satisfaction with their tobacco-related care and overall care. Patient-reported receipt of each 5A step was significantly associated with greater patient satisfaction with tobacco-related care and with overall health care, even after adjusting for a smoker's readiness to quit smoking. Satisfaction with overall health care increased as counseling intensity increased. Patient reports of smoking cessation interventions delivered during primary care practice are associated with greater patient satisfaction with their health care, even among smokers not ready to quit. Providers can follow USPHS guidelines with smokers without fear of alienating those not yet considering quitting.

Consenso sobre o tratamento da dependência de nicotina

Têm sido atribuídas à dependência de nicotina 20% das mortes nos EUA. Estudos têm mostrado que 30% a 50% das pessoas que começam a fumar escalam para um uso problemático. Nos últimos 20 anos, a educação e a persuasão não foram suficientes para promover uma mudança política, cultural e social relacionada ao comportamento de fumar. As intervenções para interromper o uso de tabaco ainda não estão integradas às rotinas dos serviços de saúde no mundo. A falta de estratégias de integração, de tempo disponível para acoplar ações assistenciais mais específicas e mesmo a percepção dos profissionais de saúde de que os tratamentos para a dependência de nicotina são pouco efetivos são algumas das barreiras apontadas. Assim, elaborar um consenso sobre a dependência de nicotina teve como objetivos: • levantar dados epidemiológicos relevantes relacionados ao uso do tabaco no mundo e no Brasil; • revisar as ações gerais e centrais da nicotina; • elaborar um protocolo de triagem mínimo para serviços de atenção primária à saúde; • recomendar diretrizes básicas de avaliação, diagnóstico e tratamento para todos os níveis de atenção à saúde em relação à dependência de nicotina; • fornecer sugestões para a abordagem de grupos especiais de pacientes: adolescentes, gestantes, idosos, pacientes em regime de internação, obesos e pacientes com comorbidades psiquiátricas, cardiovasculares e respiratórias.
