Stirnadel-Farrant, H. A., Xu, X., Kwiatek, J., Jain, P., Meyers, J., Candrilli, S., Mines, D., & Datto, C. J. (2023). Characteristics, treatment patterns, health care resource utilization and costs in patients with bullous pemphigoid: A retrospective analysis of US health insurance claims data. JAAD International, 13, 117-125. https://doi.org/10.1016/j.jdin.2023.04.014
BACKGROUND: Real-world data describing the impact of incident bullous pemphigoid (BP) on patients and health care resource utilization (HCRU) are limited.
OBJECTIVE: To examine characteristics, treatment patterns, HCRU, and costs for incident BP.
METHODS: Retrospective analysis of 2015 to 2019 US health insurance claims for patients ≥18 years with an incident BP diagnosis. Patients with BP were matched to those without on demographic and clinical characteristics. Statistics were descriptive.
RESULTS: The mean Charlson Comorbidity Index score was higher for patients with BP (
n = 1108) than without (
n = 4621) at baseline (mean [SD]: 3.3 [2.7] vs 2.8 [2.4]) and during follow-up (5.0 [4.9] vs 3.7 [3.0]). Hypertension, diabetes, skin ulcers, chronic pulmonary disease, dyslipidemia, sleep disorders, and congestive heart failure were higher with BP. Most patients with BP received antibiotics (>80%) and/or corticosteroids (>90%). Hospitalizations were more common (44.0% vs 17.1%) and monthly all-cause health care costs more than double ($3214 vs $1353) in patients with BP than without.
LIMITATIONS: Diagnoses were based on billing codes. HCRU claims data may not reflect the true number of encounters.
CONCLUSION: Incident BP is associated with considerable morbidity, HCRU, and costs. More effective, targeted treatments are needed to improve quality of life, while minimizing exposure to systemic corticosteroids.
