Withdrawal of care: a 10-year perspective at a Level I trauma center.

BACKGROUND: Withdrawal or limitation of care (WLC) in trauma patients has not been well studied. We reviewed 10 years of deaths at our adult Level I trauma center to identify the patients undergoing WLC and to describe the process of trauma surgeon-managed WLC.
METHODS: This is a retrospective review of WLC. Each patient was assigned to one of three modes of WLC: care withdrawn, limited or no resuscitation, or organ harvest. Frequency, timing, and circumstances of WLC, including family involvement, ethics committee consultation, palliative care, and hospice, were reviewed.
RESULTS: From 2000 through 2009, 375 patients died with WLC (54% of all deaths; 93% at ≥ 24 hours). For age ≥ 65 years, 80% were WLC. Overall, 15% had advance directive documents. Traumatic brain or high cervical spine injury was the cause of death in 63%. Factors associated with WLC included age, comorbidities, injury mechanism and severity, and nontrauma activation status. At time of death, 316 (84%) WLC were under trauma surgeon management. In this group, mode of WLC was care withdrawn in 74%, organ harvest in 20%, and limited or no resuscitation in 6%. Rationale for WLC in non-organ harvest patients was poor neurologic prognosis in 86% and futility in 76%. When family was identified, end-of-life discussions with physicians occurred in 100%. Conflicts over WLC occurred in 6.6% and were not associated with any demographic group. Ethics committee was involved in 2.8%. For care-withdrawn patients, median time to death from first WLC order was 6.6 hours. Palliative care and hospice consults (6% and 9%) increased yearly.
CONCLUSIONS: WLC occurred in over 50% of all trauma deaths and exceeded 90% at ≥ 24 hours. Hospice and palliative care were increasingly important adjuncts to WLC. Guidelines for WLC should be developed to ensure quality end-of-life care for trauma patients in whom further care is futile. LEVEL OF EVIDENCE: III, therapeutic study.
