A recent German study published in The BMJ reveals that a short course of talking therapy conducted by general practitioners can alleviate symptoms of post-traumatic stress disorder (PTSD) among survivors of critical illnesses. Although the effects of this psychological intervention were modest, researchers suggest it could serve as a bridge during extended waiting periods between discharge from intensive care units (ICUs) and access to specialized mental health services. With approximately one in five ICU patients experiencing PTSD symptoms, and primary care often being the main source of aftercare due to limited mental health resources, this trial introduces an innovative approach to addressing these gaps.

In response to the lack of structured interventions for PTSD symptoms within primary care settings, a team of researchers initiated a trial involving 319 adults across Germany. Participants had an average age of 58, with 61% being men. They were divided into two groups: one receiving three structured GP consultations alongside eight follow-up nurse interactions focused on PTSD symptoms, while the other group received enhanced standard care. The severity of PTSD symptoms was assessed using the post-traumatic diagnostic scale (PDS-5), ranging from 0 to 80, where higher scores indicate more severe symptoms.

At the onset of the trial, both groups reported an average PDS-5 score of 30.6. After six months, the intervention group experienced a reduction of 6.2 points in their PDS-5 scores compared to just 1.5 points in the control group, marking a difference of 4.7 points. By twelve months, the intervention group's average PDS-5 score decreased by 7.9 points versus 2.5 points in the control group, reflecting a difference of 5.4 points. Despite falling short of the clinically significant six-point threshold, researchers attribute this to the brevity and low intensity of the intervention, which restricts substantial symptom alleviation.

Notably, improvements were observed in related outcomes such as depression, disability, and quality of life, underscoring the broader positive impact of reducing PTSD symptoms on overall patient well-being. However, the researchers acknowledge certain limitations, including the exclusion of individuals with severe PTSD symptoms and the provision of only brief training for participating GPs. While unmeasured factors might have influenced the results, they emphasize the potential feasibility and benefits of integrating such interventions into general practice, given the prevalence of PTSD symptoms following critical illness and prolonged waitlists for specialist mental health services.

An editorial accompanying the study highlights its significance as a step forward in trauma-informed primary care interventions, effectively connecting acute care with long-term psychological support. Though not a substitute for specialized psychiatric treatment, these models present a practical strategy to mitigate the psychological toll of critical illness, particularly in healthcare systems with constrained specialist resources. As research progresses, refining these early interventions without compromising therapeutic efficacy remains a key challenge. Future studies should concentrate on enhancing therapy content, optimizing care delivery, and ensuring comprehensive integration across healthcare systems.
