title: Observation unit experience for pediatric poison exposures.
abstract: BACKGROUND
  Short-Stay Emergency Department Observation Units (OU) are an alternative to hospitalization, but data on OU care of pediatric poisoning exposures is limited. We report the experience of a pediatric OU with this population.
  
  
  METHODS
  We retrospectively reviewed the charts of children with poison exposure admitted to a pediatric OU during a 30-month period. Data was collected pertaining to demographics, type of exposure, clinical presentation, and rate of hospitalization, and was compared to nonpoisoned OU patients.
  
  
  RESULTS
  Of the 91 pediatric patients with poison exposure, 86 complete charts were available for review (94.5%). Of these patients, 49.5% were female, and 82.4% were <6 years of age (range 1.5 months to 16.6 years). There were a total of 98 toxicants implicated, the most common of which were psychoactive drugs (25%) and cardiovascular agents (19%). At OU admission, 33 of 88 patients (38%) had altered mental status or abnormal vital signs. Only 2 of the 53 remaining patients developed abnormal vital signs within the OU. Two patients were hospitalized unexpectedly with respiratory distress due to hydrocarbon and charcoal aspiration pneumonitis, respectively; the unexpected hospitalization rate was 2.2%. Three more planned hospitalizations for endoscopy or psychiatric evaluation led to a total hospitalization rate of 5.4%. This hospitalization rate is significantly lower (RR=0.26, 95% CI=0.11-0.62) than the hospitalization rate from the OU for nonpoisoned patients (20.3%) during that time. Mean OU length of stay for nonadmitted poisoned patients was 14.35 hours. There were no adverse events noted as a result of OU placement.
  
  
  CONCLUSIONS
  Select poisoned pediatric patients appear suitable for OU management and had less frequent unexpected hospitalization from the OU than other diagnoses.
