Prospective Outcomes of Injury Study: recruitment, and participant characteristics, health and disability status

Abstract

The Prospective Outcomes of Injury Study aims to identify predictors of disability following injury. Participants were selected from the entitlement claims register of New Zealand's no-fault compensation insurer, the Accident Compensation Corporation, and followed up by interview for 2 years. This report describes changes to intended Prospective Outcomes of Injury Study methods and key characteristics of the cohort, with an emphasis on general health and disability before injury and soon afterwards. There were 2856 injured participants in the first interview, which occurred 3.2 months (median) after injury. The recruitment period was extended to enable inclusion of sufficient Māori participants. At the first interview, most participants were experiencing worse health status and increased disability compared to before injury, despite less than one-third reporting admission to hospital because of their injury. Analysis of outcome predictors related to post-injury function, disability and return-to-work soon after injury and 1 year later is now under way.

Injury characteristics and EQ-5D as predictors of personal wellbeing after injury

“…The Prospective Outcomes of Injury Study (POIS) is a prospective longitudinal study of 2856 injured people interviewed (postal questionnaires were conducted for a minority) up to four time points in the 24 months since injury (Derrett et al, 2011). Participants were aged 18-64 years, from one of five regions of New Zealand (NZ) and injured between June 2007 and May 2009.…”

“…People with injuries caused by self-harm or sexual assault were excluded from the study. The protocol for this study has been described fully elsewhere (Derrett et al, 2009(Derrett et al, , 2011.…”

Pacific peoples three months after injury: a comparison of outcomes between Pacific and non‐Pacific participants in a NZ cohort study

“…20,21 In brief, ethics approval was obtained from the NZ Health and Disability Multi-region Ethics Committee (MEC/07/07/093). The study population was recruited from NZ residents aged 18 to 64 years, who had been referred to the Accident Compensation Corporation's (ACC) entitlement claims register from an accredited healthcare professional as a result of an acute injury event.…”

“…The study population was recruited from NZ residents aged 18 to 64 years, who had been referred to the Accident Compensation Corporation's (ACC) entitlement claims register from an accredited healthcare professional as a result of an acute injury event. 21 ACC is NZ's no fault injury insurance provider, entitling claimants to income compensation (up to 80% of pre-injury income if in paid employment), medical treatment and social rehabilitation services. 22 Individuals referred to ACC following self-harm or sexual assault injury are not included in the study.…”

“…Potential participants resided in one of the five regions of NZ -Auckland, Manukau City, Gisborne, Otago and Southland. 21 POIS data was mainly collected by telephone interview, although a minority completed postal questionnaires if this was preferred. This paper uses data from the first interview, approximately three months after injury, in which participants were asked questions that assessed the pre-injury characteristics of the cohort and early outcomes.…”
