Identification of substance use disorders in burn patients using simple diagnostic screening tools (AUDIT/DAST-10)

Substance use is disproportionately high in burn patients and associated with adverse outcomes. Screening methods for substance use disorders may help predict or avoid adverse outcomes. The University of Utah Burn Center records self-reported Alcohol Use Disorders Identification Tests (AUDIT) and Drug Abuse Screening Tests (DAST-10) for all adult burn admissions. This study assessed for association between AUDIT/DAST-10 scores and burn patient outcomes.

A retrospective chart review of adult burn patients admitted to the University of Utah from 05/01/2014-06/30/2017. Patient demographics, injury data, and substance use data were collected and analyzed.

322 patients underwent AUDIT/DAST-10 screening (n = 322). 56 (17.4%) had positive AUDIT screens (score ≥ 8). 15/50 with alcohol use at time of injury (TOI) had negative AUDIT screens. Median AUDIT score with TOI alcohol use was 12, without TOI alcohol use was 1. 30/55 patients offered alcohol counseling accepted. 14 patients (4.3%) had positive DAST-10 screens (score ≥3). 9/25 with drug use at TOI had negative DAST-10 screens. No patients without TOI drug use had DAST-10 scores >2. 9/11 patients offered drug counseling accepted. Mean standardized length of stay (LOS) per TBSA burn injury was 1.7 days for positive AUDIT, 1.6 days for negative AUDIT. Median standardized LOS was 1.4 days for positive DAST-10, 1.7 days for negative DAST-10.

AUDIT and DAST-10 screens can identify burn patients with problematic substance use, allowing early intervention. Positive screening scores do not independently predict longer hospital stays, increased wound severity, or treatment noncompliance.
