title: Predicting length of hospital stay and cost by aneurysm grade on admission.
abstract: To determine the relationship between clinical grade on admission and treatment cost after aneurysm rupture, the authors retrospectively examined the length of hospital stay (LOS) and total hospitalization costs (excluding professional fees) for 543 patients admitted for aneurysm surgery between 1983 and 1993. The overall median LOS was 18 days, with a range of 1 to 165 days. Increased median LOS correlated with Hunt and Hess Grades 0 to IV on admission (p < 0.001). Median LOS for Grade V patients was reduced, in part, because of early mortality. Increased treatment cost also correlated with worse admission clinical grade (p < 0.001). A significant proportion of total expenditures occurred early in the hospitalization for patients in all clinical grades. Identification of additional factors affecting the cost of aneurysm treatment is indicated to complement treatment outcome studies.
