Inpatient Observation After Transition From Intravenous to Oral Antibiotics

Abstract

OBJECTIVES: Children hospitalized with infections are commonly transitioned from intravenous (IV) to enteral (per os [PO]) antibiotics before discharge, after which they may be observed in the hospital to ensure tolerance of PO therapy and continued clinical improvement. We sought to describe the frequency and predictors of in-hospital observation after transition from IV to PO antibiotics in children admitted for skin and soft tissue infections (SSTIs). METHODS: We conducted a retrospective cohort study of children with SSTIs discharged between January 1, 2016, and June 30, 2018, using the Pediatric Health Information System database. Children were classified as observed if hospitalized ≥1 day after transitioning from IV to PO antibiotics. We calculated the proportion of observed patients and used logistic regression with random intercepts to identify predictors of in-hospital observation. RESULTS: Overall, 15% (558 of 3704) of hospitalizations for SSTIs included observation for ≥1 hospital day after the transition from IV to PO antibiotics. The proportion of children observed differed significantly between hospitals (range of 4%–27%; P < .001). Observation after transition to PO antibiotics was less common in older children (adjusted odds ratio [aOR] = 0.69; 95% confidence interval [CI] 0.52–0.90; P = .045). Children initially prescribed vancomycin (aOR = 1.36; 95% CI 1.03–1.79; P = .032) or with infections located on the neck (aOR = 1.72; 95% CI 1.32–2.24; P < .001) were more likely to be observed. CONCLUSIONS: Children hospitalized for SSTIs are frequently observed after transitioning from IV to PO antibiotics, and there is substantial variability in the observation rate between hospitals. Specific factors predict in-hospital observation and should be investigated as part of future studies aimed at improving the care of children hospitalized with SSTIs.
