A 9-Point Risk Assessment for Patients Who Inject Drugs Requiring Intravenous Antibiotics May Allow Health Systems to Focus Inpatient Resources on Those at Greatest Risk of Ongoing Drug Use.

Academic Article


  • A 9-point risk assessment (IVAT) identified persons with a history of injection drug use (IDU) safe for discharge. "Low risk" patients were discharged with outpatient antibiotics; others continued inpatient treatment. IVAT reduced ALOS by 20 days and total direct cost by 33%, creating capacity for an additional 333 patients.
