DRGs and the "negative" trauma workup.

We conducted a study to assess the financial impact of the diagnostic workup and care of 136 trauma patients admitted to our institution during a six-month period who were subsequently found to have only minor injuries (Injury Severity Score less than or equal to 9, Abbreviated Injury Score less than 3). The New Jersey DRG reimbursement system, an all-payer system, failed to provide adequate financial compensation overall, as the average loss per patient (operating cost minus reimbursement) was $508. Lost potential revenue (hospital charges minus reimbursement) was even greater, averaging $1,834 per patient. We conclude that the New Jersey DRG reimbursement system, in its current form, provides inadequate reimbursement for the system, in its current form, provides inadequate reimbursement for the proper workup and treatment of trauma patients with minor injuries. Because these patients are those most likely to help "subsidize" the care of sicker patients, changes in the system are necessary to allow hospitals to continue to provide state-of-the-art trauma care and to continue to minimize the number of preventable deaths due to trauma.
