Background: The burden of chronic obstructive pulmonary disease (COPD) is high. Health benefits can be gained in primary care by early detection and preventive measures. Aims: To compare the effectiveness of two strategies for population-based early detection of COPD, taking into account different socioeconomic status (SES) settings. Methods: Practices were randomised on strategy and stratified on SES setting. The Respiratory Health Screening Questionnaire (RHSQ) was distributed to all participants. In the practice-managed condition, the practice was responsible for the whole procedure, while in the patient-managed condition, patients were responsible for calculating their RHSQ risk score and applying for a spirometry test. The main outcome measure was the rate of COPD diagnoses after screening. Results: More new COPD patients were detected in the practice-managed condition (36%) than in the patient-managed condition (18%). In low SES practices, more high-risk patients were found (16%) than in moderate-to-high SES practices (9%). Recalculated for a standard Dutch practice (2,350 patients), the yield would be 8.9 new COPD diagnoses, which is a 20% increase of known cases. Conclusions: The practice-managed variant of this screening procedure shows a substantial yield of new COPD diagnoses for both low and moderate-to-high SES practices.
