Development of a Standard Set of Outcome Domains and Proposed Measures for Chronic Obstructive Pulmonary Disease in Primary Care Physical Therapy Practice in the Netherlands: a Modified RAND/UCLA Appropriateness Method.

Background: Standardization of measures in a common set opens the opportunity to learn from differences in treatment outcomes which can be used for improving the quality of care. Furthermore, a standard set can provide the basis for development of quality indicators and is therefore useful for quality improvement and public reporting purposes. The aim of this study was to develop a standard set of outcome domains and proposed measures for patients with COPD in Dutch primary care physical therapy practice, including a proposal to stratify patients in subgroups.
