OBJECTIVES: The optimal treatment duration for vancomycin-resistant enterococcal (VRE) bacteraemia is still a matter of debate. The aim of the present study was to compare short-course (≤9 days) and long-course (≥10 days) antibiotic treatments in hospitalized adult patients with uncomplicated VRE bacteraemia.
METHODS: This retrospective study was conducted in four university hospitals in Germany. Adult patients with a positive blood culture for a VRE were screened from 1 January 2016 to 31 December 2018. Only patients who received a VRE-active antibiotic for at least 48 hours were included. The exclusion criteria were a survival of <10 days and a deep-seated source of infection requiring prolonged treatment. To compare the outcome of short-course therapy with that of long-course therapy, 30-day and 90-day overall mortality, relapse within 90 days, duration of hospitalization, and potential antibiotic-related adverse events were analysed by inverse probability of treatment weighting using the propensity score and by additional covariate adjustment.
RESULTS: Of the 363 patients screened, 219 (60.3%) patients were included in the final analysis. Among them, 48 (21.9%) patients had underlying haematological diseases. Seventy-eight (35.6%) patients received short-course treatment (median, 7 days; interquartile range, 5-8 days) and 141 (64.4%) patients received long-course treatment (median, 15 days; interquartile range, 12-23.5 days). Thirty-day mortality was similar in both groups (19.2% vs. 22.0%; adjusted OR, 1.15; p 0.773). Duration of hospitalization (in total and after onset of bacteraemia) was significantly shorter (p < 0.05) in the short-course treatment group, whereas other secondary outcome parameters did not differ between both groups.
DISCUSSION: Our study suggests that short-course treatment might not be associated with a worse outcome in patients with uncomplicated VRE bacteraemia.
