Survival, Quality of Life, and Charges in Critically III Surgical Patients Requiring Prolonged ICU Stays

Critical care consumes a significant portion of health care costs.Although there are currently increasing pressures to limit expenditures, data are not always available to allow physicians and patients to make informed therapeutic or triage decisions regarding prolonged intensive care unit (ICU) stays. The purpose of this study was to evaluate long-term outcome, quality of life, and charges in surgical patients requiring prolonged ICU stays (>14 days). METHODSAdults requiring over 14 days of surgical ICU care from January 1991 to September 1993 were selected from our ICU data base. Survivors to hospital discharge were evaluated for outcome and quality of life by mail survey and/or telephone interview in addition to chart review. RESULTSEighty-three patients spent over 14 days in the surgical ICU during the study period. Fifty-two patients (62.6%) survived to hospital discharge. Average age was 53 years, average ICU length of stay was 26 days, and average hospital length of stay was 50 days. Complete follow-up data were available for 39 patients (75%). Thirty of the 39 patients (77%) were alive at an average follow-up of 18 months. Long-term survival in patients over 65 years old was 67% compared with 83% for younger patients (p < 0.05). Seventy percent reported less than 50% functional recovery. Seventy percent were living at home and 23% were on disability. Of 11 patients employed before discharge, five had returned to work. Eighty percent of respondents reported good to fair quality of life, and 81% stated that they would undergo critical care again. The average ICU charge was $51,512 per patient, and the average hospital charge was $164,019 per patient. The average charge to achieve one long-term survivor was $2447,813. CONCLUSIONSIn this population, prolonged ICU stays resulted in acceptable quality of life and a relatively high survival rate despite significant economic investment. This study does not support withdrawal of therapy or triage decisions based solely or primarily on age or length of ICU stay.
