Determinants of inpatient treatment in children with orbital cellulitis

Orbital cellulitis in children can lead to serious complications and necessitate hospitalization for management. This study investigated predictors of inpatient hospitalization among pediatric patients receiving medical treatment for orbital cellulitis. A retrospective cohort study of children treated for orbital cellulitis at West Virginia University Children's Hospital from January 2012–July 2022 was conducted. Patient characteristics, treatment setting (inpatient vs outpatient), orbital cellulitis type (preseptal vs postseptal), etiology of the orbital cellulitis (acute rhinosinusitis vs other), and presence of subperiosteal abscess were reviewed. The sample consisted of 100 pediatric patients with mean age of 7.0 years old (SD = 4.9). Inpatient treatment was required for 70 patients with a mean length of stay of 3.0 (SD = 1.7) days. In univariate regressions, acute rhinosinusitis (ARS), postseptal cellulitis, and subperiosteal abscess predicted necessitating inpatient treatment ( p < 0.05 for all). In multivariate regressions, only ARS predicted treatment setting ( p = 0.016) and no variables predicted length of stay ( p > 0.05 for all). In children who were treated medically for orbital cellulitis, ARS as the etiology was the main predictor necessitating inpatient treatment. 4
