Abstract: With increasing implementation of casemix-based funding for hospitals, quantitative data were needed to confirm the clinical impression that treating Aboriginal (compared with non-Aboriginal) inpatients consumes significantly more resources. Utilisation data, collected over a three-month period in 10 hospitals, were used to determine a cost per inpatient episode, which was grouped according to AN-DRG-3 to give a cost per AN-DRG for Aboriginal and Torres Strait Islander (ATSI) patients and non-ATSI patients. ATSI patients had consistently longer average length of stay and significant variation in relative frequency of admissions, compared with non-ATSI patients, with higher prevalences of infectious diseases. Degenerative and neoplastic conditions were more common in non-ATSI patients. There were significant differences in casemix-adjusted costs per patient episode (ATSI, $1856; non-ATSI, $1558; P < 0.001). Our study has quantified differential resource consumption between two Australian populations, and highlights the need for recognition of some hospitals' atypical populations and special funding requirements.
