Long-term outcome in ICU patients: what about quality of life?

Abstract

Objective: Analysis of mortality and quality of life (QOL) after intensive care unit (ICU) discharge.

Design: Prospective, observational study.

Setting: Mixed, 31-bed, medico-surgical ICU.

Patients: Consecutive adult ICU admissions between June 25 and September 10, 2000, except admissions for uncomplicated elective postoperative surveillance. INTERVENTIONS. None.

Measurements and results: Age, past history, admission APACHE II, SOFA score (admission, maximum, discharge), ICU and hospital mortality were recorded. A telephone interview employing the EuroQol 5D system was conducted 18 months after discharge. Of 202 patients, 34 (16.8%) died in the ICU and 23 (11.4%) died in the hospital after ICU discharge. Of the 145 patients discharged alive from hospital, 22 could not be contacted and 27 (13.4%) had died after hospital discharge. Of the 96 patients (47.5%) who completed the questionnaire, 38% had a worse QOL than prior to ICU admission, but only 8.3% were severely incapacitated. Twenty-three patients (24%) had reduced mobility, 15 (15.6%) had limited autonomy, 24 (25%) had alteration in usual daily activities, 29 (30.2%) expressed more anxiety/depression, and 42 (44%) had more discomfort or pain. Twenty-eight (62.2% of those who worked previously) patients had returned to work 18 months after ICU discharge.

Conclusions: Comparing QOL after discharge with that before admission, patients more frequently report worse QOL for the domains of pain/discomfort and anxiety/depression than for physical domains. Factors commonly associated with a change in QOL were previous problems in the affected domains, prolonged hospital length of stay (LOS), greater disease severity at admission and degree of organ dysfunction during ICU stay.
