OBJECTIVE: To estimate the annual, per-patient incremental burden of diabetic foot ulcers (DFUs). RESEARCH DESIGN AND METHODS: DFU patients and non-DFU patients with diabetes (controls) were selected using two de-identified databases: ages 65+ years from a 5% random sample of Medicare beneficiaries (Standard Analytical Files, January 2007-December 2010) and ages 18-64 years from a privately insured population (OptumInsight, January 2007-September 2011). Demographics, comorbidities, resource use, and costs from the payer perspective incurred during the 12 months prior to a DFU episode were identified. DFU patients were matched to controls with similar pre-DFU characteristics using a propensity score methodology. Per-patient incremental clinical outcomes (e.g., amputation and medical resource utilization) and health care costs (2012 U.S. dollars) during the 12-month follow-up period were measured among the matched cohorts. RESULTS: Data for 27,878 matched pairs of Medicare and 4,536 matched pairs of privately insured patients were analyzed. During the 12-month follow-up period, DFU patients had more days hospitalized (+138.2% Medicare, +173.5% private), days requiring home health care (+85.4% Medicare, +230.0% private), emergency department visits (+40.6% Medicare, +109.0% private), and outpatient/physician office visits (+35.1% Medicare, +42.5% private) than matched controls. Among matched patients, 3.8% of Medicare and 5.0% of privately insured DFU patients received lower limb amputations. Increased utilization resulted in DFU patients having $11,710 in incremental annual health care costs for Medicare, and $16,883 for private insurance, compared with matched controls. Privately insured matched DFU patients incurred excess work-loss costs of $3,259. CONCLUSIONS: These findings document that DFU imposes substantial burden on public and private payers, ranging from $9-13 billion in addition to the costs associated with diabetes itself.
