Bronchiolitis: Can objective criteria predict eligibility for brief hospitalization?

To determine if 3 objective criteria – pulse oximetry, respiratory syncytial virus (RSV) testing, and age – could be used to predict which children hospitalized with bronchiolitis will have brief (<36 hour) hospitalizations and therefore be potential candidates for admission to short-stay observation units. This was a retrospective medical record review of medically uncomplicated children 3 to 24 months of age with emergency department and hospital discharge diagnoses consistent with bronchiolitis who were admitted to a general pediatric ward in our university-based, tertiary care hospital between Jan. 1, 1992, and Nov. 12, 2002. Multiple logistic regression was used to assess the predictor variables. Our study consisted of 225 patients (45% female) with a median age of 7 months (interquartile range [IQR], 4–11 mo; range, 3–22 mo). Median pulse oximetry value was 94% (IQR 91%–96%; range 76%–100%), and 71% of the patients tested positive for RSV. Thirty children (13%) had brief hospitalizations <36 hours, and the median hospital length of stay for the entire study group was 70 hours (IQR 46–108 h; range 6–428 h). None of the 3 predictor variables were independently associated with brief hospitalization. Pulse oximetry, RSV testing and age do not predict which children will have brief hospitalizations and are appropriate candidates for admission to short-stay observation units.
