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.

Eligibility |
Inclusion Criteria: Primary care physicians were eligible if they: 1) managed at least 15 patients with asthma and 15 patients with COPD per month in an office setting; and 2) agreed to designate an appropriately trained person at his/her site to identify eligible study patients, collect consent, and provide a questionnaire to patients. Patients were eligible if they: 1) spoke French or English; and 2) had a diagnosis of asthma or COPD (as per their participating PCP). Furthermore, patients with asthma had to be between 18 and 45 years of age, and patients with COPD had to be between 40 and 75 years of age and have a smoking history of >10 pack-years. Exclusion Criteria: Physicians were excluded if they: 1) had presented at a continuing medical education (CME) event on asthma or COPD in last year; 2) had completed any specialty training in respiratory diseases; or 3) practiced primarily at walk-in clinics, with children, or in emergency departments. Patients were excluded if they: 1) had any condition which could interfere with study measurements (as per their participating PCP); 2) had any known respiratory disorders other than asthma or COPD; or 3) were currently participating in another clinical trial. |

Primary | Physician Assessment Questionnaire-Asthma | 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. |
First visit | No |
Secondary | The Physician Practice Assessment Questionnaire | 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) | First visit | No |
