Because of concern about increasing health care costs, we undertook a study to find patient risk factors associated with increased hospital costs and to evaluate the relationship between increased cost and in-hospital mortality and serious morbidity.
More than 100 patient variables were screened in 1221 patients undergoing cardiac procedures.
Simultaneously, patient hospital costs were computed from the cost-to-charge ratio.
Univariate and multivariate statistics were used to explore the relationship between hospital cost and patient outcomes, including operative death, in-hospital morbidity, and length of stay.
The greatest costs were for 31 patients who did not survive operation ($74,466,95% confidence interval $27,102 to $198,025), greater than the costs for 120 patients who had serious, nonfatal morbidity ($60,335,95% confidence interval $28,381 to $130,897, p=0.02) and those for 1070 patients who survived operation without complication ($31,459,95% confidence interval $21,944 to $49,849, p=0.001).
Breakdown of the components of hospital costs in fatalities and in cases with nonfatal complications revealed that the greatest contributions were in anesthesia and operating room costs.
Significant (by stepwise linear regression analysis) independent risks for increased hospital cost were as follows (in order of decreasing importance) : (1) preoperative congestive heart failure, (2) serum creatinine level greater than 2. (...)
