Implementing practice guidelines: a workshop on guidelines dissemination and implementation with a focus on asthma and COPD.

The present supplement summarizes the proceedings of the symposium "Implementing practice guidelines: A workshop on guidelines dissemination and implementation with a focus on asthma and COPD", which took place in Quebec City, Quebec, from April 14 to 16, 2005. This international symposium was a joint initiative of the Laval University Office of Continuing Medical Education (Bureau de la Formation Médicale Continue), the Canadian Thoracic Society and the Canadian Network for Asthma Care, and was supported by many other organizations and by industrial partners. The objectives of this meeting were to examine the optimal implementation of practice guidelines, review current initiatives for the implementation of asthma and chronic obstructive pulmonary disease (COPD) guidelines in Canada and in the rest of the world, and develop an optimal strategy for future guideline implementation. An impressive group of scientists, physicians and other health care providers, as well as policy makers and representatives of patients' associations, the pharmaceutical industry, research and health networks, and communications specialists, conveyed their perspectives on how to achieve these goals. This important event provided a unique opportunity for all participants to discuss key issues in improving the care of patients with asthma and COPD. These two diseases are responsible for an enormous human and socioeconomic burden around the world. Many reports have indicated that current evidence-based guidelines are underused by physicians and others, and that there are many barriers to an effective translation of recommendations into day-to-day care. There is therefore a need to develop more effective ways to communicate key information to both caregivers and patients, and to promote appropriate health behaviours. This symposium contributed to the initiation of what could become the "Canadian Asthma and COPD Campaign", aimed at improving care and, hence, the quality of life of those suffering from these diseases. It is hoped that this event will be followed by other meetings that focus on how to improve the transfer of key recommendations from evidence-based guidelines into current care, and how to stimulate research to accomplish this.

Higher BMI is associated with worse asthma control and quality of life but not asthma severity.

Asthma and obesity tend to co-occur, but relatively few studies have linked obesity, measured using body mass index (BMI), to clinically relevant measures of asthma morbidity. This study assessed BMI in a Canadian sample of asthma outpatients, and evaluated associations between BMI and levels of asthma severity, asthma control, and asthma-related quality of life. A total of 382 adult asthma patients underwent demographic and medical history interviews on the day of their clinic visit. Patients' self-reported height and weight were used to calculate BMI (kg/m(2)). Asthma severity was classified according the GINA (2002) guidelines. Patients completed the Asthma Control (ACQ) and Asthma Quality of Life (AQLQ) Questionnaires and underwent standard pulmonary testing (spirometry). A total of 139 (36%) patients had a normal BMI; 149 (39%) patients were overweight; and 94 (25%) patients were obese. There was no relationship between BMI and asthma severity when controlling for age and sex. Patients with higher BMI scores had higher ACQ and lower AQLQ scores, independent of age, sex and asthma severity. Results identify higher BMI and obesity as potential behavioral factors related to worse asthma control and quality of life, but not asthma severity, and suggest important avenues for asthma management and control initiatives.

Are psychiatric disorders associated with worse asthma control and quality of life in asthma patients?

BACKGROUND: Achieving good asthma control has become the major goal of asthma treatment. Studies have reported a high rate of psychiatric disorders among asthma patients, though the impact of these disorders on asthma control and quality of life remains unexplored. This study evaluated the prevalence of psychiatric disorders in 406 adult asthma patients, and associations between psychiatric status, levels of asthma control, and asthma-related quality of life. METHODS: Consecutive asthma patients presenting to the asthma clinic underwent a brief, structured psychiatric interview, completed the Asthma Control Questionnaire (ACQ) and Asthma Quality of Life Questionnaire (AQLQ), and reported the frequency of bronchodilator use in the past week. All patients underwent standard pulmonary function testing. RESULTS: A total of 34% (n=136) of patients had one or more psychiatric diagnosis, including major depression (15%), minor depression (5%), dysthymia (4%), panic disorder (12%), generalized anxiety disorder (5%), and social phobia (4%). Though there were no differences in pulmonary function, patients with versus without psychiatric disorders had worse ACQ and AQLQ scores and reported greater bronchodilator use, independent age, sex and asthma severity. CONCLUSIONS: Results suggest that psychiatric disorders are prevalent among asthmatics and are associated with worse asthma control and quality of life. Physicians should be aware of the potential risk of poorer asthma control and functional impairment in this population.

An effective strategy for diagnosing occupational asthma: use of induced sputum.

Monitoring airway inflammation by means of induced sputum cell counts seems to improve the management of asthma. We sought to assess whether such monitoring at the end of periods at and away from work combined with the monitoring of PEF could improve the diagnosis of occupational asthma. We enrolled subjects suspected of having occupational asthma. Serial monitoring of PEF was performed during 2 weeks at and away from work. At the end of each period, induced sputum was collected. Specific inhalation challenge was subsequently performed. PEF graphs were interpreted visually by five independent observers. Forty-nine subjects, including 23 with positive specific inhalation challenge, completed the study. The addition of sputum cell counts to the monitoring of PEF increased the specificity of this test, respectively, by 18 (range [r] 13.7-25.5) or 26.8% (r 24.8-30.4) depending if an increase of sputum eosinophils greater than 1 or 2% when at work was considered as significant. The sensitivity increased by 8.2% (r 4.1-13.4) or decreased by 12.3% (r 3.1-24.1) depending on the cutoff value in sputum eosinophils chosen (greater than 1 or 2%, respectively). The addition of sputum cell counts to PEF monitoring is useful to improve the diagnosis of occupational asthma.

Occupational asthma.

PURPOSE OF REVIEW: The scientific literature on occupational asthma is steadily increasing and no longer only describes case reports with prevalence figures and limited physiopathologic and immunologic data. Prospective cohort studies are currently carried out with relevant incidence figures and risk factors. Genetic susceptibility is explored. New diagnostic means are described. Surveillance programs are conducted and preventive measures are proposed. RECENT FINDINGS: A relevant account was published on the respiratory consequences (irritant-induced asthma, a type of occupational asthma) of exposure of firefighters at the World Trade Center site. Glutathione-S-transferase appears to be an interesting susceptibility gene for occupational asthma as a result of isocyanates. Inflammation caused by neutrophils and not only by eosinophils is more often associated with occupational asthma. Examination of induced sputum and assessment of exhaled nitric oxide are becoming useful diagnostic tools. Cleaners are at increased risk of developing occupational asthma, although the causal agents are unknown. Surveillance programs currently combine strategies that aim to reduce exposure and identify cases early. SUMMARY: New scientific information provides better, accurate figures on the frequency of occupational asthma and on risk factors, proposes relevant diagnostic tools more directly related to the physiopathology of the disease, and suggests effective surveillance programs in high-risk workplaces.

Reactions of health professionals to a research-based theatre production.

BACKGROUND: There is a recent trend in the social sciences--predominantly among researchers engaged with qualitative methodologies--to translate research finding into artistic and narrative forms. In this paper, we describe our work in translating finding about the experiences of men with prostate cancer and their spouses into a dramatic production, No Big Deal? We then report upon, and provide commentary about data from interviews with health professionals who attended a performance. METHODS: Health professionals (N = 26) were interviewed within 2 weeks of attending a performance of No Big Deal? and again 6 months later (N = 23). RESULTS: After attendance at the performance, many study participants reported (at both interview times): new awareness or understanding about the issues facing prostate cancer patients; reinforcements of their positive attitudes and behaviors in relation to patients; an increased sense of connection with ill people; and plans to alter their clinical practices to better meet patient needs. CONCLUSIONS: Narrative and dramatic forms are viable ways to communicate vital information about the possibilities for professionals to be helpful to patients--and they are the wave of the future for educational and dissemination practices.

Utilization of complementary/alternative services by women with breast cancer.

This paper reports on the utilization of complementary/alternative medicine (CAM) services by women with breast cancer. Study participants were women with invasive breast cancer diagnosed 23-36 months prior to contact about the study, and randomly selected from the Ontario Cancer Registry. From among 1,119 eligible women sent survey questionnaires, 731 returned completed questionnaires (65%). A total of 20% of respondents used at least 1 CAM service. Among those who responded to a question about whether they would have liked specific services, 39% reported that there was at least one CAM service they would have liked to use, but were unable to access. Factors shown to be related to greater utilization of services included: younger age, higher household income, employed or student status, private health insurance coverage, and having received chemotherapy. Study results speak to the importance of acknowledging that professionals outside of the formal cancer care system play an important role for many patients. Patients would welcome experimentation with service models in which CAM practitioners and cancer specialists collaborate in providing care.

Supportive care provided by physicians and nurses to women with breast cancer. Results from a population-based survey.

Breast cancer patients' utilisation of supportive care has been understudied. In this paper, results from a population-based survey are used to assess the role of physicians and nurses in providing supportive care to women. Participants for this study were women with histologically confirmed invasive breast cancer diagnosed 23-36 months prior to contact about the study, who were randomly selected from the Ontario Cancer Registry. Patients for whom a physician approved contact were sent a survey questionnaire. There were two follow-up mailings. The survey included items related to patients' perceptions of supportive care involvement of oncologists, surgeons, family physicians and nurses. Among 1,119 eligible patients, 65% returned completed questionnaires. A total of 72% of these women reported having talked with an oncologist about one or more supportive care issues; 78% with a surgeon; 73% with a family physician; and 45% with a nurse. Factors linked to seeking supportive care from physicians and/or nurses included: younger age, working status, higher education, additional health insurance beyond that provided by government, higher household income, and receiving chemotherapy. Results indicate that physicians and nurses were providing important supportive care to most women with breast cancer. In a health care context where specialised supportive care services (e.g. help from dietitians, psychologists, social workers) are often unavailable or difficult to access, supportive care remains largely a responsibility of medical and nursing professionals. Even brief interventions may make an important difference to how patients deal with their illness over time.

Active consideration: conceptualizing patient-provided support for spouse caregivers in the context of prostate cancer.

In this study, the authors examine the under-investigated topic of patient-provided support for spouse caregivers. Thirty-four men with prostate cancer and their female partners were interviewed separately three times: before the man's radical prostatectomy, 8 to 10 weeks postsurgery, and 1 year postsurgery. The core category of active consideration encompassed 4 dimensions: easing spousal burden, keeping us up, maintaining connection, and considering spouse. Patient-provided support entails two overlapping tasks: minimizing the practical and emotional impact of the illness and tending to the caregiver's social-emotional needs. A theory expounding on the double bind of being both a patient and an agent in light of masculine socialization practices is articulated and brought to bear on the phenomenon of patient-provided support.
