Area of Science:

• Cardiology
• Pulmonary Medicine
• Health Services Research

Background:

• Pulmonary Arterial Hypertension (PAH) requires guideline-adherent management for optimal patient outcomes.
• The Pulmonary Arterial Hypertension-Quality Enhancement Research Initiative Extension Program aimed to improve guideline adherence.
• Physician adherence to clinical guidelines is crucial for effective PAH treatment.

Purpose of the Study:

• To evaluate the effectiveness of the Pulmonary Arterial Hypertension-Quality Enhancement Research Initiative Extension Program.
• To assess physician adherence to PAH guidelines across different patient functional classes.
• To identify factors influencing adherence to PAH treatment guidelines.

Main Methods:

• Prospective evaluation of a quality enhancement program.
• Analysis of physician adherence to PAH guidelines at 36 months.
• Stratification of adherence data by patient functional class (FC II/III vs. FC IV).

Main Results:

• High adherence (>95%) to PAH guidelines was observed for patients with functional class II/III.
• Adherence to PAH guidelines significantly decreased to 28.6% for functional class IV patients at 36 months.
• Patient preference to avoid parenteral treatment was the primary driver for low adherence in FC IV patients.

Conclusions:

• The quality enhancement program successfully improved PAH guideline adherence for most patients.
• Functional class IV patients present a unique challenge to guideline adherence, particularly regarding parenteral therapies.
• Further strategies are needed to address FC IV patient preferences and improve adherence in advanced PAH.
