QUALITY-OF-LIFE MEASURES BEFORE AND ONE-YEAR AFTER ADMISSION TO AN INTENSIVE-CARE UNIT

Objective: To assess outcome of patients admitted to an intensive care unit (ICU), using a prospective 1-yr follow-up, with special emphasis on various quality of life measures before and after admission to the ICU. Design: Prospective comparison of quality of life before and 1 yr after admission to the ICU. Setting: Eleven-bed adult medical/surgical ICU. Patients: All patients admitted to the ICU over a 1-yr period were eligible for inclusion in this study. Repeat admissions were enrolled only on first admission. Patients < 17 yrs of age and those patients who died within 24 hrs of admission were excluded. Interventions: Quality of life measures were collected before and 6 and 12 months after ICU admission. Measurements and Main Results: The following data were collected: duration of ICU and hospital stay; ICU, hospital, 6- and 12-month mortality; quality of life (level of activity, activities of daily living, perceived health, support, and outlook on life) and place of residence at baseline and 12 months after ICU admission. There were 504 patients who met the study criteria; age 55 +/- 20 yrs (median 59), 229 female and 275 male. Mean ICU length of stay was 4.3 +/- 7.4 days. Hospital length of stay was 31 +/- 41 days. Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 14 +/- 7. Cumulative mortality: ICU 5.4%, hospital 13.5%, 6 month 20.6%, and 12 month 25%. One year quality of life questionnaires were completed for 293 patients. Relative to baseline, there was a decrease in the level of activity and activities of daily living at 12 months (p < .01). Perceived health status increased over the year for patients greater than or equal to 75 yrs of age (p < .01). There was no difference in the level of support from family or friends, or outlook on life, at 12 months. At 1 yr, 262 (89%) patients were living at home. Conclusion: Patients admitted to intensive care tend to have a decrease in the level of activity and activities of daily living 1 yr after their ICU stay, although in the very elderly, perceived health status increases. As well, the majority (89%) of patients return home.
