title: Diagnostic and therapeutic procedures among Australian hospital patients identified as indigenous.
abstract: OBJECTIVE
  To determine whether hospital patients identified as Indigenous are less likely than other inpatients to have a principal procedure recorded, and the extent to which any disparity in procedure use can be explained by differences in patient, episode and hospital characteristics.
  
  
  METHODS
  Retrospective analysis of routinely collected administrative data from the National Hospital Morbidity Database (NHMD).
  
  
  METHODS
  Australian public and private hospitals.
  
  
  METHODS
  All patients included in the NHMD whose episode type was recorded as acute and whose separation occurred between 1 July 1997 and 30 June 1998. Patients admitted for routine dialysis treatment were excluded.
  
  
  METHODS
  Whether a principal procedure was recorded.
  
  
  RESULTS
  In public hospitals, patients identified as Indigenous were significantly less likely than other patients to have a principal procedure recorded, even after adjusting for patient, episode and hospital characteristics (adjusted odds ratio [OR], 0.67; 95% CI, 0.66-0.68). This disparity was apparent for most diseases and conditions. In private hospitals, no significant difference was observed (adjusted OR, 0.94; 95% CI, 0.83-1.06).
  
  
  CONCLUSIONS
  The disparity in procedure use after adjustment for relevant factors indicates that in Australian public hospitals there may be systematic differences in the treatment of patients identified as Indigenous.
