Māori experience injury and disability inequities. Our Prospective Outcomes of Injury Study (POIS) has investigated a range of Māori post-injury outcomes to two years post-injury, adding to a current knowledge gap. Maximising the opportunity POIS provides, POIS-10 Māori aims to understand and improve long-term (12 years post-injury) outcomes and experiences (positive and negative) for injured Māori and their whānau, using key Māori models of health and well-being. We will follow-up Māori POIS participants (N=544) for POIS-10 Māori, collecting data via quantitative telephone interviews, linking ACC and hospitalisation e-data to 12 years post-injury to understand and identify the factors contributing to key outcomes; and, qualitatively explore the experiences of, barriers and facilitators of access to services, via face-to-face interviews with 15-20 purposively selected participants and their whānau. POIS-10 Māori will provide vital insights about the complex injury and rehabilitation pathway to improve long-term outcomes and experiences, and identify intervention opportunities.
