From Clinic to Comfort: The Impact of Frequent Pulmonary Clinic Visits on Advanced COPD Hospitalizations - A Retrospective Case-Control Study of Two University Hospitals.

Our study suggests that frequent outpatient pulmonary clinic visits in patients with advanced COPD significantly reduce COPD-related hospitalizations, improve guideline-directed management, and enhance preventive care. While a direct mortality benefit was not statistically significant, the reduction in hospitalizations rate suggests potential indirect survival benefit. Further controlled studies are needed to validate these findings and inform future COPD-related healthcare policies.
