title: Paediatric walk-out patients: characteristics and outcomes.
abstract: OBJECTIVE
  To investigate the characteristics and outcomes of patients who walked out from a tertiary children's hospital emergency department (ED) without seeing a medical officer.
  
  
  METHODS
  A prospective study of patients who walked-out from the ED of a children's hospital, without seeing a medical officer. Information collected at triage included demographics, presenting problems, time of arrival, time of departure and reason for leaving. Charts were reviewed and those at high risk of serious illness or adverse outcome were contacted by telephone within 24 h. Further information collected during follow up included outcome, such as adverse events and admission to hospital. Data were analysed by comparing the walk-out and non-walk-out groups with regard to demographic variables, presenting problems and outcomes.
  
  
  RESULTS
  Over a 29 week period, 1037 (5.5%) patients walked out from the ED of the hospital without seeing a medical officer. Comparisons between the walk-out and non-walk-out patients indicated no differences in terms of demographics. However, significant differences were found between the triage categories, presenting problems and arrival time. Of these, 829 (79.9%) were followed up by telephone. This revealed the predominant presenting problem was non-urgent and infectious in nature and no adverse events occurred. The admission rate for walk-out patients (1.5%) was significantly lower in comparison with the non-walk-out group (6.9%; odds ratio 0.2; 95% confidence interval 0.1-0.3). Walk-out patients who were eventually hospitalized had a shorter mean length of stay than non-walk-out patients (20.4 vs 34.8 h, respectively; t = 17.78, P < 0.0001).
  
  
  CONCLUSIONS
  Medical resources are limited and, therefore, some extended waiting in the ED is necessary. Paediatric patients who walk-out of the ED without seeing a medical officer have simple illnesses that resolve without medical intervention or adverse events.
