Abstract
Background. Acute bacterial skin and skin-structure infections (ABSSSIs) are common causes of hospital admissions. These infections are often caused by methicillin-resistant Staphylococcus aureus; therefore, vancomycin remains a commonly used therapy. The purpose of this study was to compare hospital length of stay (LOS) in patients treated with vancomycin monotherapy vs combination therapy with clindamycin for ABSSSIs.
Methods. This was a retrospective analysis of 269 patients admitted with ABSSSIs to a 941-bed hospital in northern Alabama. Patients who received either vancomycin monotherapy or vancomycin in combination with clindamycin were included. The primary outcome was hospital LOS; secondary outcomes included 90-day readmission rate and the impact of the following on the primary outcome: organisms cultured, presence of abscess, incision and debridement (I&D), failure of a trial of outpatient antibiotics, and presence of diabetes.
Results. Hospital LOS was similar between groups when evaluating all ABSSSIs (3.7 ± 1.5 days vs 4.0 ± 2.0 days, P = .192, combination and monotherapy, respectively). In patients with abscesses, combination therapy was significantly associated with decreased LOS by 18.2% compared with monotherapy (95% confidence interval [CI], 0.818 [.679 to .985]; P = .034). Among the entire population, significantly fewer patients in the combination group were readmitted within 90 days (5.3% vs 15.3%; P = .006; odds ratio [OR], 3.2; 95% CI [1.35 to 7.66]). The 90-day readmission rates were significantly lower among patients with abscesses as well (2.0% vs 24.3%; P = .0001; OR, 14.6; 95% CI [2.98 to 71.37]).
Conclusions. Combination therapy with vancomycin and clindamycin was associated with decreased hospital LOS for patients with an abscess. The 90-day hospital readmission rates for those with ABSSSIs may be reduced when combination therapy is utilized. A larger, prospective, multicentered study is needed to validate these findings.
