Effects of Clinical Pathways for COPD on Patient, Professional, and Systems Outcomes: A Systematic Review.

Background: COPD has a substantial burden seen in both patient quality of life and health-care costs. One method of minimizing this burden is the implementation of clinical pathways (CPWs). CPWs bring the best available evidence to a range of health-care professionals by adapting guidelines to a local context and detailing essential steps in care.

Methods: A systematic review was conducted to address the following question: What are the effects of CPWs for COPD on patient-, professional-, and systems-level outcomes? The review used methods outlined by the Cochrane Collaboration. We included all studies that met our operational definition for CPWs and focused on COPD. All studies were evaluated for risk of bias, and all data regarding patient, professional, and systems outcomes were extracted.

Results: The search strategy identified 497 potentially relevant titles. Of these, 13 studies were included in the review. These studies reported a total of 398 outcomes, with sufficient data for meta-analysis of five outcomes: complications, length of stay, mortality, readmissions, and quality of life. Results showed statistically significant reductions in complications, readmissions, and length of stay but did not show changes in mortality or quality of life.

Conclusions: This systematic review reveals evidence to suggest that CPWs for COPD have the potential to reduce complications, readmissions, and length of stay without negatively influencing mortality or quality of life. However, quality of evidence was generally low. The authors therefore acknowledge that results should be interpreted with caution and note the need for additional research in this area.
