Introduction: Females with haemophilia A (HA [FHAs]) and HA carriers (HACs) have an increased risk of bleeding and complications compared to the general population. Aim: To examine the characteristics, billed annualised bleed rates (ABRb), costs and healthcare resource utilisation for males with HA (MHAs), FHAs and HACs in the United States. Methods: Data were extracted from the IBM® MarketScan® Research Databases (Commercial and Medicaid) for claims during the index period (July 2016 to September 2018) and analysed across MHAs, FHAs and HACs. Results: Dual diagnosis females (DDFs; both HA and HAC claims) were grouped as a separate cohort. MHAs were generally younger than females (all cohorts) by up to 19 years (Commercial) and 23 years (Medicaid). ABRb >0 was more frequent in females. Factor VIII claims were higher for MHAs versus female cohorts. Joint‐related health issues were reported for 24.4 and 25.6% (Commercial) and 29.3 and 26.6% (Medicaid) of MHAs and FHAs, respectively; lower rates were reported in the other two cohorts. Heavy menstrual bleeding claims occurred for approximately a fifth (Commercial) to a quarter (Medicaid) of female cohorts. All‐cause emergency department and inpatient visits in FHAs and DDFs were similar to, or more frequent than, those in MHAs; bleed‐related inpatient visits were infrequent. In MHAs (Commercial), mean all‐cause total costs ($214,083) were higher than in FHAs ($40,388), HACs ($15,647) and DDFs ($28,320) with similar trends for Medicaid patients. Conclusions: FHAs and HACs may be undermanaged and undertreated. Further research is needed to fully understand these cohorts' bleeding rates, long‐term complications and costs.
