Abstract

Abstract: Introduction: Current in‐hospital burden and healthcare utilization patterns for persons with haemophilia (PWH) A and B, including both children (ages < 18 years) and adults (ages ≥ 18 years), in the United States (US) are lacking. Aim: To evaluate healthcare utilization, the prevalence of comorbidities, and mortality in hospitalized paediatric and adult PWH using a contemporary nationally representative cohort. Methods: Hospitalizations of PWH either as the primary reason for admission (principal diagnosis) or one of all listed diagnoses were identified using ICD‐10 codes from the 2017 Nationwide Inpatient Sample (NIS), the largest publicly available all‐payer inpatient discharge database in the US. Sampling weights were applied to generate nationally representative estimates. Results: The contemporary cohort included 10, 555 hospitalizations (paediatrics, 18.3%; adults, 81.7%) among PWH as one‐of‐all listed diagnoses ( n = 1465 as principal diagnosis). Median age (interquartile range) was 46 (24–66) years overall; adults, 54 (35–70) years and paediatric, 4 (1–11). The most common comorbidities in adults were hypertension (33.4%), hyperlipidaemia (23.6%), and diabetes (21.1%). In children, hemarthrosis (11.4%), contusions (9.6%), and central line infections (9.3%) were the most common. The overall mortality rate was 2.3%. Median hospital charges per haemophilia admission were $52, 616 ($24, 303–$135, 814) compared to $26, 841 ($12, 969–$54, 568) for all‐cause admissions in NIS. Conclusion: Bleeding and catheter‐related infections are the significant reasons for paediatric haemophilia admissions. Adult haemophilia admissions tend to be associated with age‐related comorbidities. Costs for haemophilia‐related hospitalizations are higher than the national average for all‐cause hospitalizations.
