title: [Prospective study of patients who leave the emergency department before being seen by the physician].
abstract: BACKGROUND
  To define epidemiological characteristics, the main reasons, and outcome of patients who leave the emergency department (ED) without being seen by a physician.
  
  
  METHODS
  We performed a prospective survey of patients who left the ED before medical visit over a period of 26 consecutive weeks. For every non-visited patient (NV), the next visited patient (V) was included as a control. Clinical and epidemiological data, reasons to leave ED and outcome were obtained from clinical records and personal telephone interview.
  
  
  RESULTS
  Out of a total of 21,022 patients who were attended in the ED, 383 (1.8%) were NV. To be under 50-year-old, to come the ED alone, to be previously visited by a community physician, and to previous expect short waiting times for ED visit were associated with higher risk for being NV (p < 0.01, p < 0.01, p < 0.05 and p < 0.0001, respectively). The main reasons noted to leave the ED were: feeling better (35%), feeling too sick to wait longer (30%) and being too angry to wait (25%). Only 46% of the NV looked for medical care in the 72 following hours and 6.5% of them needing to be further to hospital. NV-patients considered as suffering a serious pathology at ED arrival, and those being visited by a community physician previously to go to ED were found to be at increased risk to be subsequently admitted (p = 0.01 and p = 0.001, respectively).
  
  
  CONCLUSIONS
  Patients who leave ED department before being seen by a doctor are usually young, literate, have not previously visited their community physician, and consulted for minor complaints. The main reason to leave is their own impression of suffering a minor disease, and less than 50% visit another physician after their leaving, being the rate of hospital admission low. We should be particularly cautious with those patients referred by a community doctor and those identified as to have a seriously affected health status at their arrival at the hospital, since they are at increased risk to be admitted.
