title: Incidence and impact of undisclosed cocaine use in emergency department chest pain and trauma patients.
abstract: BACKGROUND
  One of the highest rates of illicit cocaine consumption in Europe is in Spain. Our objective was to study the incidence and impact of undisclosed cocaine consumption in patients attending the emergency department (ED) for trauma or chest pain.
  
  
  METHODS
  We analysed urine samples from consecutive patients attending the ED for trauma or chest pain to determine the presence of cocaine, cannabis, amphetamine/metaamphetamine and opioids by semiquantative tests with fluorescence polarization immunoassay (FPIA).
  
  
  RESULTS
  Thirty percent of eligible patients participated. Of 75 cases, 61.3% had trauma and 38.7% chest pain; 25% presented a positive test for drugs. Cocaine was present in 13.3% and cannabis in the same proportion. No differences were found regarding positive cocaine test and chief complaint, ED or hospital stay, or additional tests. Cocaine-positive patients were significantly younger.
