Prospective Outcomes Of Injury Study (POIS)

Aims

– To quantitatively determine injury, rehabilitation, personal, social and economic factors leading to disability outcomes following injury in New Zealand; and
– To qualitatively explore people’s lived experiences and perceptions of injury-related disability outcomes.

Project Team: Sarah Derrett, John Langley, Brendan Hokowhitu, Shanthi Ameratunga, Paul Hansen, Gabrielle Davie, Emma Wyeth, Rebbecca Lilley.

Associate Investigators: Sue Wilson, Ari Samaranayaka, Helen Harcombe, Brett Maclennan, Sue McAllister, Ian Cameron, Rob McGee, Melbourne Mauiliu, Faafetai Sopoaga, Jesse Kokaua, Radilaite Cammock.

Funding: Health Research Council of New Zealand (2007-2013), Accident Compensation Corporation (2007-2010).

Between December 2007 and August 2009, 2856 New Zealanders aged 18-64 years were recruited into POIS, a longitudinal cohort study, soon after they had been injured. Recruitment was via the Accident Compensation Corporation (ACC) entitlement claimant register, and all injury types were eligible except those resulting from self-harm or sexual assault. Participants were recruited from five regions: Auckland City, Manukau City, Gisborne, Otago and Southland, to ensure inclusion of people with a range of ethnic, socioeconomic and rural/urban characteristics. POIS was specifically designed to encourage injured Māori to participate, to ensure that sufficient were recruited to allow analyses of injury outcomes specifically for this group. The study was able to recruit 566 Māori participants (20% of the cohort). There were also 239 participants of Pacific ethnicity. Participants have been interviewed up to four times (3, 5, 12 and 24 months after their injury), to obtain information about their injury experiences and outcomes to identify predictors of recovery, or not, from injury. The last of these interviews were completed in 2011. Publications report findings in relation to key outcomes including disability, functioning, economic and paid employment following injury. Analysis and dissemination of findings is on-going and further follow-up is planned.

Newsletters

At several points during POIS, newsletters were mailed out to participants and others who had assisted with the study, to keep them up-to-date with how the information provided to us was being used, most recently in July 2010 and November 2011.
