Background : As Australia’s population ages, the number of elderly patients presenting for surgery of abdominal aortic aneurysms (AAA), both elective and ruptured, will increase. The aim of the present study was to compare the costs of treatment of patients with AAA, under and over the age of 80, in the elective and emergency settings in a hospital with a divisional structure in which the true costs can be accurately obtained. Methods : A total of 40 patients were selected at random from a series of 267 patients treated with open surgery for AAA between January 1987 and December 1994, 10 in each of four groups: group A, elective repair in patients aged < 80 (171/267); group B, elective AAA repair in patients aged > 80 (25/267); group C, emergency AAA repair in patients aged < 80 (50/267); and group D, emergency AAA repair in patients aged > 80 (11/267). A retrospective analysis of the hospital costs of treatment of these patients at St George Hospital was conducted. These true costs were then compared to Australian National Diagnostic Related Group (AN‐DRG) costs. Results : Group A and B had no mortality. In Group C and D the mortality was 20 and 60%, respectively. The emergency treatment groups also had longer lengths of stay. A statistically significant difference in cost of AAA repair between elective and emergency groups in both age groups was seen; that is, group A cost less than group C and group B cost less than group D. Costs per survivor, however, showed a dramatic difference between the cost of group C patients ($30 000) and group D patients ($60 000). In comparison with AN‐DRG calculated costs, the true costs of groups A and B were equivalent to AN‐DRG costs. In the emergency groups, how‐ ever, there were marked discrepancies between the true cost ($61 000) and that calculated by the DRG ($25 000) in group D, with similar differences seen in group C to a lesser extent. Conclusion : Emergency repair of AAA is significantly more expensive and has a high mortality in the over‐80 age group. Also, there is a substantial shortfall between the true costs of treating these patients and the funds allocated for treatment in this group.
