Tracheostomy in thermally injured patients: does diagnosis-related group 483 adequately estimate resource use and hospital costs?

BACKGROUND This study compares burn and nonburn patients undergoing tracheostomy, all of whom were assigned to diagnosis-related group 483 to determine hospital reimbursement. METHODS We reviewed the records of all inpatients admitted to our hospital from January 2000 through December 2001 who underwent tracheostomy and who were assigned to diagnosis-related group 483. In addition, we compared our burn patient data with that from three other burn centers and the National Burn Repository. RESULTS We identified 357 inpatients who had tracheostomies during their hospitalization, only 12 of whom (3.4%) had acute burn injuries. The mean extent of burn in these patients was 43.4% total body surface area. The most frequent primary diagnoses for nonburn patients were injury and poisoning, and circulatory and respiratory disorders. Patients with burn injuries had 39.6 ventilator days, 40.7 intensive care unit days, and 49.2 hospital days compared with 19.8, 17.4, and 29.5 days, respectively, for nonburn patients (p <0.0001). Demographic, resource, and financial data for burn patients treated at the three other burn centers and those reported to the National Burn Repository were not significantly different from burn patients treated at our hospital. Total costs and charges for the care of burn patients were $186,830 and $343,904, respectively, compared with $82,176 and $160,498 for the nonburn patients (p <0.0005). CONCLUSION Burn patients requiring tracheostomies during their acute hospitalization consume significantly more resources than patients without burn injuries. More appropriate resource-based reimbursement for the care of these patients appears warranted.
