While physical injuries are often closely monitored and treated, the University of Otago (Christchurch) Faculty of Medicine research showed the psychological impact of trauma was frequently overlooked.
The three studies examined the prevalence of PTSD following severe injury, the gap between symptoms and diagnosis, and the barriers patients face navigating care and ACC support during recovery.
Now the researchers are calling for improved long-term psychological support for survivors of major trauma.
The first study, led by Health New Zealand (HNZ) Waitaha Canterbury clinician Dr Daniel Jemberie, found 18% of the 203 patients studied suffered severe trauma and experienced ‘‘probable PTSD’’.
Those at greatest risk were younger patients, those with an initially altered level of consciousness and people involved in vehicle-related trauma.
A second study, led by HNZ Waitaha Canterbury clinician Dr Nikita Quinn, revealed a ‘‘concerning gap’’ in diagnosis and mental healthcare.
Despite the high prevalence of probable PTSD, only 22% of the same 203 affected patients had received a formal diagnosis, while more than half had never undergone any mental health assessment.
The third study, led by HNZ Waitaha Canterbury clinician Dr Sarah Logan, explored the wider systemic barriers survivors face once they leave hospital.
It found nearly 15% of the 134 patients studied reported difficulties accessing follow-up care, while 25% experienced challenges navigating ACC processes.
Patients screening positive for PTSD, anxiety or depression were between three and five times more likely to report problems with healthcare follow-up or ACC support.
Research supervisor Dr Chris Wakeman said the findings collectively highlighted the pressing need for a more comprehensive and patient-centred approach to trauma recovery.
‘‘For many patients, the psychological impact of trauma can persist for months or years, affecting their ability to return to work, maintain relationships and regain a sense of normality.’’
Dr Wakeman said he hoped the studies would increase awareness of the hidden burden experienced by survivors of serious injury.
