Abstract
Introduction: This study aimed to describe the clinical characteristics of patients with pulmonary arterial hypertension, treatment received, and factors predicting initial or earlier combination therapy.
Methods: The Adelphi Real World Pulmonary Arterial Hypertension (PAH) Disease Specific Programme™ is a cross-sectional survey with retrospective data collection conducted in the USA, Europe (France, Germany, Italy, Spain, and the UK), and Japan from March to August 2022. Physicians reported patient characteristics, treatment history, and reasons for treatment selection. Descriptive statistics were grouped by country and World Health Organization functional classification. A multivariable Cox regression analysis investigated factors predicting initial or earlier combination therapy use.
Results: Data for 1173 patients was provided by 293 physicians. Patients' mean (standard deviation) age was 58.7 (13.8) years and 54.6% were female. Overall, 91.2% of patients were receiving, or had previously received, PAH-specific treatment. About three-quarters of the cohort were still taking the initial treatment strategy: for this group, 54% were prescribed monotherapy and 32% combination therapy; 15% of patients received supportive therapy alone. The proportion of patients receiving PAH-specific treatment was lowest in the USA (82.0%) and highest in France (94.6%). The proportion of patients receiving PAH on combination therapy was lowest in the USA (23.8%) and highest in Germany (36.5%). Treatment was prescribed for PAH in 87.6%, 89.8%, 89.3%, and 75.0% of patients who were functional class I, II, III, and IV, respectively, and combination therapy usage was more likely for those with more advanced functional class. Higher risk status, care by a pulmonologist, Japanese residence, more complete assessments, and hospitalization in the past 12 months were statistically associated with decreased time to combination therapy for PAH. Older age was statistically associated with increased time to combination therapy.
Conclusion: In this real-world, geographically diverse sample, monotherapy treatment was common, even among patients with advanced disease.
期刊介绍:
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
