title: Anonymous cocaine screening in a private obstetric population.
abstract: OBJECTIVE
  To establish the prevalence of cocaine use in private obstetric patients during their prenatal care and at admission to delivery units.
  
  
  METHODS
  Urine samples were collected anonymously during routine sampling from 1425 patients in six private hospitals and four private physicians' offices.
  
  
  RESULTS
  Positive cocaine metabolites were identified in three of 555 urine specimens (0.54%) obtained from hospitals and in two of 870 (0.23%) obtained from private offices during prenatal examinations. The total positive urine cocaine results were five of 1425 (0.35%).
  
  
  CONCLUSIONS
  Universal screening in a private obstetric population similar to that found in Denver would not be cost-effective. We urge health care providers to ask patients about substance abuse and to screen patients who are at high risk for substance use.
