Summary

Diagnostic overshadowing occurs when a pre-existing condition influences the assessment of other diagnoses. This study examines how substance use disorder (SUD) affects the time to surgical intervention in patients with traumatic brain injuries, revealing that SUD leads to delays in care. The findings demonstrate that diagnostic overshadowing impacts surgical timeliness and is measurable.
