Effects of a brief primary care intervention for post-traumatic stress disorder symptoms after critical illness on health-related quality of life - A secondary analysis of the PICTURE randomised controlled trial.

TL;DR

A secondary analysis of the PICTURE RCT found that a brief GP-delivered narrative exposure intervention improved health-related quality of life (HRQoL) in ICU survivors with PTSD symptoms, with transient VAS improvements at 6 months and delayed EQ index improvements at 12 months. Only about one-quarter of the 12-month HRQoL benefit was mediated by PTSD symptom reduction, suggesting additional mechanisms of action.

Key findings

• Brief primary care psychological intervention yielded clinically meaningful HRQoL improvements over 12 months in ICU survivors with moderate-to-severe PTSD symptoms
• Treatment effects on HRQoL emerged in staggered pattern: early VAS improvement (6 months) followed by delayed EQ index improvement (12 months)
• PTSD symptom reduction accounted for only ~25% of the 12-month HRQoL improvement, indicating other therapeutic mechanisms
• Domain-level improvements most pronounced in anxiety/depression and mobility domains

Why this matters at the bedside

Demonstrates that primary care-based brief interventions for post-ICU PTSD can yield sustained HRQoL benefits beyond symptom reduction alone, supporting the feasibility of GP-delivered psychological care for critical illness survivors in resource-limited settings.
