Asthma & COPD Guideline Implementation
This is a report of a protocol developed to improve asthma and COPD care in a primary care setting. The study was approved by an Ethics Committee and support by the Canadian Thoracic Society through an unrestrictive grant from GlaxoSmithKline. However, the study could not be done and the investigators report why, discussing the difficulties to perform such study. This information should be very useful to investigators planning this sort of study.

- Physician Assessment Questionnaire-Asthma [ Time Frame: First visit ] [ Designated as safety issue: No ]
The co-primary outcomes (for asthma and COPD) were defined as the change in patient-reported physician conformity to each of the following key guideline recommendations, measured through a questionnaire (Appendix 1):
A) For asthma, assessment of asthma control, defined as ascertainment of at least 2 of the 5 asthma control questions recommended by the Canadian Asthma Guidelines. Stratified physician randomization would randomize 75% of PCPs to the TIS group and 25% to the SP group.
- The Physician Practice Assessment Questionnaire [ Time Frame: First visit ] [ Designated as safety issue: No ]Secondary outcomes collected through the patient questionnaires included other guideline-recommended physician behaviours. For asthma, these included spirometry performance, asthma action plan provision and review, inhaler technique review, and maintenance anti-inflammatory medication prescription when indicated. For COPD, these included spirometry performance, inhaler technique review, exacerbation screening, long-acting bronchodilator prescription when indicated, and smoking cessation efforts in smokers. A separate questionnaire measured physician self-reported changes in knowledge and adherence to guideline-recommended behaviours (the "Physician Practice Assessment Questionnaire") (PPAQ)

Active Comparator: Standard practice group (SPG)
Send a copy of the latest Canadian asthma and COPD guidelines to all PCPs.
Other: Standard Practice Group (SPG)
The investigators planned to send a copy of the latest Canadian asthma and COPD guidelines to all PCPs in the Standard Practice (SP) Group at the start of the study period, by mail. No other intervention would be offered during the study, but upon study completion, all control participants would be offered the educational intervention received by the Targeted Intervention Strategy (TIS) Group.

Asthma and chronic obstructive pulmonary disease (COPD) are the two most common chronic pulmonary ailments in Canada, affecting about 2.5 million and 750 thousand individuals, respectively. In the last two decades, the Canadian Thoracic Society (CTS) has successfully developed and disseminated evidence-based asthma and COPD clinical practice guidelines. However, evidence suggests that guideline implementation in these diseases remains inadequate.
Successful guideline implementation requires tailoring of selected strategies to settings and population-specific barriers, based on established theories and principles. In 2004, the CTS and its collaborators organized a symposium in Quebec City, to discuss existing barriers to respiratory guideline implementation and possible knowledge translation (KT) strategies. This was followed in the fall of 2007 by an expert-led workshop on guideline implementation strategies.
Herein, the investigators report the planned methods and outcome of a project which resulted from these meetings. This study sought to explore the effectiveness of a multi-faceted KT strategy in improving concordance with COPD and asthma guidelines among primary care physicians (PCPs) in Canada, but was aborted due to inadequate PCP recruitment. The investigators discuss the difficulties encountered in recruiting PCPs, factors which may have influenced recruitment, and alternative strategies. The goal of the investigators is to provide practical lessons to inform the design of future KT initiatives with similar interventions and/or a similar target audience.
