Overview

Longitudinal cohort analysis reveals ICD-11 criteria reduce PTSD diagnosis rates by 47% to 57% relative to ICD-10, indicating potential undertreatment of moderate cases.

Key Points

To assess differences in diagnosis rates, symptom severity, and diagnostic overlap when applying proposed ICD-11 versus ICD-10 criteria to recent trauma survivors.
Analyzed pooled data from N=3,863 trauma survivors across 11 longitudinal studies of PTSD.
Applied ICD-10 and ICD-11 diagnostic algorithms to Clinician-Administered PTSD Scale (CAPS) evaluations between trauma exposure and 15 months of follow-up.
ICD-11 criteria diagnosed 47.09% to 57.14% fewer PTSD cases than ICD-10 across all assessment intervals, with over 97% of ICD-11 cases concurrently meeting ICD-10 criteria.
Individuals meeting ICD-11 criteria had 31.38% to 36.49% higher CAPS symptom severity scores than those meeting only ICD-10 criteria, though the latter group still exhibited moderate PTSD symptoms.
ICD-11 cases showed similar or higher rates of comorbid mood and anxiety disorders, while longitudinal symptom trajectories remained similar regardless of which system established the initial diagnosis.
