Treatment of Cellulitis in Diabetic Patients

Initial Assessment and Treatment Approach

The Infectious Diseases Society of America recommends that cellulitis associated with penetrating trauma requires coverage for both streptococci and Staphylococcus aureus 1, 3
For a patient with a mild, non-purulent cellulitis, the American College of Physicians suggests management as an outpatient, with a recommended duration of antimicrobial therapy of 5 days, but treatment should be extended if the infection has not improved within this time period 2

The American College of Physicians recommends first-line oral options for outpatient treatment, including dicloxacillin, cephalexin, and amoxicillin-clavulanate, for patients with cellulitis 2, 3
Consider MRSA coverage if there are risk factors such as previous MRSA infection, known MRSA colonization, local high prevalence of MRSA, or failure to respond to beta-lactam therapy 1, 4

The American Diabetes Association notes that diabetic patients require more vigilant monitoring due to increased risk of infection progression and potential for delayed wound healing 1, 2

The American College of Physicians recommends elevation of the affected finger to reduce edema, as an adjunctive measure to antibiotic therapy 2, 4

The Infectious Diseases Society of America suggests re-evaluating the patient within 48-72 hours to assess response to therapy, and considering changing antibiotics if no improvement after 48 hours, or extending treatment beyond 5 days if clinical improvement is slow 2
