Indirect Costs and Family Burden of Pediatric Crohn's Disease in the United States.

Abstract

Crohn's disease (CD) negatively impacts patient quality of life and results in greater healthcare utilization. For pediatric CD patients, the burden also extends to their caregivers. We aimed to estimate work loss and productivity costs among caregivers of pediatric CD patients. Data were from Truven MarketScan databases (2000-2012). Patients were <18 years old with ≥2 ICD-9 CD diagnostic codes. Controls were those without CD or ulcerative colitis and were matched to patients by age, Charlson Comorbidity Index, index year, and insurance plan category. Continuous enrollment was required ≥6 months before and ≥12 months after index, defined as the patient's first CD diagnosis date. Outcomes included hours of work loss and associated productivity costs of caregivers 1-year postindex. Work loss and productivity costs were compared between caregivers of patients and controls. Adjustments for unbalanced baseline factors were made using a generalized linear regression model. Each cohort included 200 study participants and their caregivers. Unadjusted annual hours of work loss after first diagnosis were 214.4 ± 171.5 and 169.6 ± 157.5 for caregivers of CD patients and controls, respectively (P = 0.007). Annual productivity costs were 27.2% ($1122) higher for caregivers of CD patients than controls, estimated at $5243 and $4,121, respectively (P = 0.004). Adjusted cost analyses yielded similar findings. Over the course of a patient's childhood, accumulated productivity losses were $24,118 for CD patients and $18,957 for control caregivers. Caregivers of pediatric CD patients have significantly higher loss in productivity costs compared with controls.
