ObjectiveTo compare direct (medical and drug) and indirect (work loss) costs between privately insured US employees with Dupuytren's contracture (DC) and demographically matched controls without DC.MethodsEmployees aged 18-64 with ≥ 1 DC diagnosis (ICD-9-CM: 728.6, 718.44) with service dates 1/1/2000-3/31/2009 were selected from a de-identified, privately insured claims database (n∼3,000,000). The index date was defined as the most recent DC diagnosis with continuous eligibility for 6 months prior (baseline period) and 1 year after (study period) diagnosis. Employees with DC were matched 1:1 on age, region, gender, and index date to controls without DC, Peyronie's, or Ledderhose disease diagnoses in their claims histories. Descriptive analyses compared demographic characteristics, comorbidities, resource utilization, direct costs, and indirect costs inflated to 2009 dollars.ResultsDC employees (n=1406, mean age 49 years) with matched controls met the inclusion criteria. DC employees compared with controls had significantly (all p<0.05) higher baseline comorbidities, including hyperlipidemia (21.1% vs 15.6%), hypothyroidism (3.5% vs 2.0%), cancer (3.1% vs 1.5%), and diabetes (8.1% vs 3.6%). During the study period, DC employees had significantly (all p<0.01) higher rates of inpatient stays (7.7% vs 5.3%), emergency department visits (19.8% vs 13.9%), outpatient visits (100.0% vs 78.4%), physical therapy visits (30.2% vs 7.2%), and any prescription use (85.0% vs 69.2%), as well as higher mean work loss days (14.2 vs 7.3). DC employees had on average significantly (all p<0.01) higher annual direct costs ($5974 vs $3175), indirect costs ($2737 vs $1309), and total costs ($8712 vs $4485) compared with controls during the study period.LimitationsFindings did not account for lost productivity at work and were based on a privately insured, employed population, which may not be generalizable to all DC patients.ConclusionsEmployees with DC had substantially higher comorbidity rates, utilization, and direct and indirect costs compared with demographically matched controls.
