Long-term survival, prognosis, and life-care planning for 29 patients with chronic locked-in syndrome

Abstract

We present a life-table analysis of a cohort of 29 locked-in syndrome (LIS) patients followed for a minimum of five years, and we report on the status of the chronic LIS patient. Twenty-nine LIS patients who remained locked-in for more than one year were identified. Inpatient charts were reviewed for demographic, medical, and functional data. Telephone followup was obtained to examine medical complications after discharge, survival, neurologic recovery, care issues, and permanent disposition. A life-table analysis was performed on survival data. Cerebrovascular disease was the most common cause of LIS. Survival ranged from 2.02 to 18.15 years. Twenty of the 26 patients available for five-year followup survived; hence, five-year survival was 81%. An alternative method of communication and emotional stress for the patient's caregiver was the key issue in patient care. Most patients were cared for in their own homes. Although minimal late neurologic recovery occurs in chronic LIS, survival may, nonetheless, be prolonged with adequate supportive care. Modern computerized technology offers LIS patients the ability to interact with their environment. This information may assist physicians in making ethical and long-term care decisions with the patient rather than for the patient with LIS.
