Around 35 percent of all patients with major trauma in Aotearoa New Zealand have an associated sTBI. Analysis of the New Zealand Trauma Registry suggested that how sTBI is managed and outcomes for patients who experience injury varies by population, geography and destination hospital.

This variation is not well understood, and it may affect a patient’s long-term recovery and present barriers for people who need to access the right care in the right place at the right time following serious injury.

An expert advisory group was formed to guide this project; it includes experienced allied health, medical and nursing professionals; rehabilitation provider services; and consumers and whānau with lived experience of TBI.

Key findings from initial scoping work indicate that approximately 50 percent of patients with TBI are initially admitted to non-neuroscience centres. Data from the national trauma registry suggests that both access to specialist neuroscience centres and outcomes after sTBI vary significantly by region. [1]

Traditionally, the decision to transfer a patient following sTBI is determined by whether there is an absolute or potential need for neurosurgical intervention. Neurosurgery is an essential part of sTBI management, but sTBI patients who do not require surgery also experience improved outcomes when admitted to a neuroscience centre. [2,3] This is likely because these centres deal with more TBI patients and have immediate access to neuro-subspecialty teams and specialist allied health and nursing staff.

Current international consensus suggests that patients with TBI (Glasgow Coma Scale [GCS] score of <9) should be admitted to a neuroscience centre regardless of their need for neurosurgery. When this policy was adopted in England, sTBI-related mortality declined significantly. [4,5] A quality improvement campaign has engaged stakeholders across the sector to develop a nationally agreed action plan and care pathway to facilitate the transfer of sTBI patients to neuroscience centres in Aotearoa New Zealand.
