The aim of this study was to report clinical outcomes of moderate and severe foot infections in patients without diabetes. Medical records of 88 nondiabetic patients with foot infections treated at a safety net hospital were retrospectively reviewed. Patients were grouped by the presence of soft-tissue infection (STI) or osteomyelitis (OM). The diagnosis of OM was determined by positive bone culture or histopathology. STIs were defined by negative bone biopsy or negative imaging with magnetic resonance imaging or computed tomography/dual-modality radiolabeled white blood cell single-photon emission computed tomography. Patient outcomes were recorded ≤1 year after admission. Eighty-eight nondiabetic patients admitted to our institution for moderate or severe foot infections were included, 45 OM and 43 STI. No differences were noted in patient characteristics except that OM patients had a higher prevalence of neuropathy (66.7% versus 39.5%, p =.02). OM patients required surgery more often (97.8% versus 67.4%, p <.01), a greater number of surgeries (2.0 ± 1.2 versus 1.4 ± 1.3, p =.02), and more amputations (75.6% versus 11.6%, p <.01) than STI patients. OM patients had a higher proportion of wounds that healed (82.2% versus 62.8%, p =.04). There were no significant differences in reinfection (35.6% versus 25.6%, p =.36), foot-related readmission to hospital (35.6% versus 23.3%, p =.25), or total duration of antibiotics (13.9 ± 10.2 versus 13.5 ± 12.9, p =.87) between OM and STI patients. In conclusion, OM patients required more surgeries and amputations than patients with STIs; however, they had similar rates of reinfection and readmission within a year after the index hospitalization.
