Economic and Social Burden of Pulmonary Arterial Hypertension in Italy: A Cost-of-Illness Study
摘要
Pulmonary arterial hypertension (PAH) is a rare, chronic and progressive disease with a significant clinical, social, and economic impact. Despite available therapies, none address the underlying cause but rather focus on symptom management.
ObjectivesThis study aims to estimate the economic and social burden of PAH in Italy, including direct healthcare costs, direct nonhealthcare costs, and indirect costs related to productivity loss.
MethodsA bottom-up prevalence-based cost-of-illness model was developed using epidemiological data and healthcare resource consumption from national and international literature, validated by a panel of expert clinicians with extensive experience in the management of the condition across different regions of Italy. The analysis was conducted from a societal perspective over a 1-year horizon.
The economic burden included direct healthcare costs (hospitalization, pharmaceuticals, and specialist care), direct nonhealthcare costs, and indirect costs related to productivity loss.
ResultsIn Italy, the prevalent population of patients with PAH is estimated between 2100 and 3500 individuals, with 2–5% in functional class (FC) I, 28–31% in FC II, 53–57% in FC III, and 7–11% in FC IV. The total annual expenditure for treatment and management is estimated between 263 million and 438 million euros, with 74% attributable to direct healthcare costs, 9% to direct nonhealthcare costs, and 17% to indirect costs. The mean annual cost per patient is approximately 125,000 € and increases with disease severity, ranging from 46,303 € for FC I to 252,176 € for FC IV.
ConclusionsPAH has a substantial economic burden, increasing with disease severity. Early diagnosis and targeted interventions could improve patient outcomes, reduce complications, and optimize resource allocation for the National Health Service and society.
