Concomitant pulmonologist and primary care for chronic obstructive pulmonary disease: a population study

Area of Science:

• Pulmonary Medicine
• Health Services Research
• Epidemiology

Background:

• Pulmonologist shortages and costs necessitate defining their optimal role in managing chronic obstructive pulmonary disease (COPD).
• Evidence-based strategies are needed to ensure efficient application of pulmonologist expertise for COPD patient needs.

Purpose of the Study:

• To evaluate if combined pulmonologist and primary care physician (PCP) care post-COPD discharge improves health outcomes compared to PCP care alone.
• To assess the association between concomitant specialist and primary care versus primary care alone on COPD-related health outcomes.

Main Methods:

• A population-based cohort study in Ontario, Canada (2004-2011) included patients discharged after a COPD-related hospital or emergency department visit.
• Propensity score matching was used to compare patients receiving both pulmonologist and PCP care with those receiving PCP care only within 30 days of discharge.
• The composite outcome of death, COPD hospitalization, or COPD emergency department visit within one year was analyzed using proportional hazards regression.

Main Results:

• In the matched sample, 1-year outcomes were similar: 39.7% in the concomitant care group and 38.9% in the PCP-only group experienced the composite outcome (aHR 1.08, 95% CI 1.00-1.17).
• Patients receiving concomitant care were more likely to undergo diagnostic testing and receive prescribed medications.
• No significant difference in mortality or COPD-related acute care utilization was observed between the two groups.

Conclusions:

• Concomitant pulmonologist and PCP care after COPD discharge did not demonstrate superior health outcomes compared to PCP care alone.
• Patients receiving combined care experienced increased diagnostic testing and medication management, suggesting potential benefits in treatment intensity.
• Further research is warranted to define the most effective integration of pulmonologist services for optimal COPD management and resource allocation.
