An ongoing study of medical care and associated costs relative to spinal cord injury is being conducted at the University of Alabama in Birmingham, one of 11 federally funded Model Regional Spinal Cord Injury Centres. It was hypothesised such costs would be lower among patients admitted into an organised continuum of care (system) soon after injury than among patients whose entry into the organised system of care was delayed (non-system). A comprehensive economic data set has been acquired on 142 of 233 (61 per cent) patients admitted since implementation of the project. Analysis of these data reveals: (1) system patients require, on average, expenditures of almost $5,000 less than their non-system counterparts; (2) there is little difference in medical or associated costs and length of hospitalisation between tetraplegics and paraplegics; (3) spinal cord injuries secondary to motor vehicle accidents have higher associated costs and longer lengths of stay than do those injuries resulting from other causes including acts of violence.
