The persistent vegetative state: An analysis of clinical correlates and costs

A review was compiled of 23 patients in the persistent vegetative state; a condition that developed while the patients were in an acute care hospital. Before the onset of the persistent vegetative state, eight patients had had dementia, 11 were functionally dependent, and seven had neurologic disorders that gradually led to the persistent vegetative state. For patients in the persistent vegetative state, three types of mechanical support-respirators, nasogastric or gastrotomy tubes, and intravenous lines-were utilized. All three were necessary in 43% of patients, two types in 52%, and one type in 4%. All patients in the persistent vegetative state required at least one type of mechanical assistance. Their course was complicated in all cases by incontinence, and in the majority, by decubiti, pneumonia, and urinary tract infection. Only one patient improved enough to be able to say a few words. These patients required active medical care and invasive procedures that were costly but futile. The hospital bills obtained for 13 patients averaged $170,000, and the length of stay for all patients averaged 197 days, the equivalent to a total number of bed-days of 12.5 bed-years. The poor outcomes, requirements for mechanical support, and frequency of complications-especially when neurologic impairments were present before the onset of the persistent vegetative state-should be considered when evaluating the cost in hospital bills and bed occupancy.
