Background:
Routine toxicology screening of seriously injured patients has become the standard of care in most trauma centers. However, the benefit of drug screening in acute trauma is unproven. We reviewed the impact of positive drug screening results on patient care within the first 3 days of treatment.
Methods:
We retrospectively reviewed the charts of seriously injured patients admitted to an American College of Surgeons-certified level I trauma center over a 5-year period. Modifications of therapeutic regimens based on positive toxicology results were noted. Using current financial data, charges for toxicology were calculated.
Results:
Between January 1, 1990, and December 31, 1995, 2,678 trauma patients had drug screening. Of these, 414 (15%) had detectable quantities of the following intoxicants: opiates, barbiturates, amphetamines, phencyclidine hydrochloride (PCP), cocaine, marijuana, or benzodiazepines. Review of all 401 available charts failed to identify any cases in which treatment was altered by a positive toxicology result. Hospital costs related to routine screening were $138,587, while charges to patients amounted to $538,278.
Conclusions:
Routine toxicology does not alter or improve the immediate care of the injured patient. Routine drug screening is expensive, and benefits were not easily documented. The policy of routine toxicology screening in trauma centers should be reevaluated.
