WITHDRAWING CARE - EXPERIENCE IN A MEDICAL INTENSIVE-CARE UNIT

Objective.-To describe the process and outcomes of withdrawing life-sustaining interventions in a medical intensive care unit (MICU). Design.-Retrospective case series. Setting.-Medical intensive care unit in a community teaching hospital. Patients.-Consecutive series of 28 patients in whom mechanical ventilation, dialysis, and/or vasopressors were withdrawn. We distinguished physiological, neurological, and functional rationales for care withdrawal. Main Outcome Measures.-Duration of discussions, MICU length of stay, and hospital survival. Results.-Mean +/-SD Acute Physiology and Chronic Health Evaluation (APACHE II) score was 27.1 +/- 7.3 on MICU admission, and average +/-SD predicted hospital mortality was 61% +/- 22%. Discussions leading to withdrawal of care occurred over an average +/-SD of 5.2 +/- 5.5 days, with decisions achieved soonest in cases with poor neurological prognosis. Average +/-SD MICU length of stay was 1.4 +/- 1.8 days following a decision to withdraw MICU care, and only four patients received more than 48 hours of additional MICU care. Four patients were discharged alive from the hospital. Conclusions.-Patients and their surrogates willingly considered outcomes in addition to mortality when considering withdrawal of life-sustaining interventions. Finding an accommodation between physician judgments and patient preferences took time and effort but was an effective means of limiting ineffective life-sustaining efforts. Withdrawing futile or unwanted care was not always fatal.
