Abstract
Injury is a leading cause of disability and is costly. This prospective cohort study extension aims to improve disability, health, and wellbeing outcomes for injured New Zealanders, including for Māori. We will identify predictors and modifiable risk factors of long-term outcomes (positive and negative), and develop an Injury Early Care Tool (INJECT) to inform the implementation of effective interventions to improve outcomes. In the Prospective Outcomes of Injury Study (POIS), 2856 people participated following an injury (occurring between 2007 and 2009) registered with New Zealand’s no-fault accident compensation scheme (ACC). POIS-10 will invite 2121 people (including 358 Māori) who completed a 24-month POIS interview and agreed to follow-up, anticipating 75% participation (n = 1591). Interviews will collect sociodemographic characteristics, life events, comorbidities, and new injuries since participants’ 24-month interview, as well as key disability, health, and wellbeing outcomes 12 years post-injury. Injury-related data will be collected from ACC and hospitalisation records 12 years post-injury. Regression models for the main outcomes will examine the direct effects of predictor variables after adjustment for a wide range of confounders. POIS-10 is enhanced by our partnership with ACC, and expert advisors and will benefit injured people, including Māori, through increased understanding of mechanisms and interventions to improve long-term post-injury outcomes.
Highlights
In New Zealand (NZ), and internationally, injury is a leading cause of disability [1,2].injury is extremely costly for individuals, families, and society
Findings from Prospective Outcomes of Injury Study (POIS) have been of proven value to NZ crown entities, including Accident Compensation Corporation (ACC), resulting in changes in long-term priorities and a renewed focus on life-course perspectives, outcomes, and hauora/wellbeing
POIS has had significant international impact, contributing data to the six-country Validating and Improving Injury Burden Estimates (Injury-VIBES) Study, which aimed to provide valid estimates of the burden of non-fatal injury by combining data from prospective cohort studies of injury outcomes undertaken in the UK, USA, Australia, NZ, and the Netherlands [49]
Summary
In New Zealand (NZ), and internationally, injury is a leading cause of disability [1,2]. The Prospective Outcomes of Injury Study (POIS) has provided extensive information about a range of disability, health, and wellbeing outcomes experienced by a large representative cohort of injured New Zealanders (n = 2856; including 566 Māori), up to 24 months post-injury [4,5]. Findings from POIS are consistent with those of a recent systematic review of 29 studies measuring health-related quality of life (HRQL) in general injury populations [8]. Injury, studies found that large functional deficits remained at two years post-injury when compared to population norms and reports of pre-injury health status [8]
