Healthcare resource utilization and costs in pediatric pulmonary arterial hypertension in a third-level hospital in Mexico.

Aim: The objective of this study was to evaluate the healthcare costs and resource utilization of pediatric pulmonary arterial hypertension management at a third-level hospital in Mexico. Methods: A retrospective cohort study was conducted in a pediatric population with pulmonary arterial hypertension. Only direct medical costs, derived from pharmacological treatment, laboratory tests, physician visits and hospitalizations, were considered. From an institutional perspective, all costs were accounted for in 2019 US dollars. Results: A total of 82 patients were included. Of these, 55% were female and the mean age was 6.9 (standard deviation ± 4) years. The mean annual cost was $17,452.14 (standard deviation ± $38,944.10), with a median cost of $8,832.75. Conclusion: Pulmonary arterial hypertension is a costly disease, with hospitalization and pharmacological treatment being areas with a higher economic burden. Functional class IV has greater resource utilization and costs.
