Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One-off remediation of certain home fall hazards identified by a home hazard inspection protocol, the Healthy Housing Index. Hazards (such as steps without handrails) are remediated (e.g., by installing a handrail) at the start of the trial for the treatment group. Remediation of the hazards will typically occur within a month of the inspection. Injuries occurring in the house are monitored for about 3 years following the intervention.
Intervention code [1] 286345 0
Other interventions
Comparator / control treatment
Status quo.
After the treatment group has received the home hazard remediations and approximately three years has passed to allow an assessment of home injury rates, home fall hazards are remediated for the controls.
Control group
Active

Outcomes
Primary outcome [1] 288661 0
Count of medically treated home fall injuries as reported to the national accident insurer, the Accident Compensation Corporation (ACC).
Timepoint [1] 288661 0
During three years following start of study ACC will record data on all unintentional home fall injuries to the participants. These will be provided periodically to the research team so that telephone interviews can be used to supplement the information on the injury events.
Secondary outcome [1] 300722 0
Self-reported home injury recorded by self-completed annual questionnaire
Timepoint [1] 300722 0
Once annually for each of the three years following start of study

Summary
Brief summary
Home injury hazards are a likely to be a major cause of injury for Maori. This study will capitalise on an existing cohort of Maori houses which are participants in the Best Outcomes for Maori : Te Hoe Nuku Roa longitudinal study. Audits of 250 Maori houses will be undertaken using the Healthy Housing Index developed by members of this research team. Half of the houses will be randomly assigned to an intervention group where remediation of selected hazards will be undertaken by professional builders. At the end of the randomised control trial, the balance of the houses will be remediated. We will also assess preparedness for earthquakes and other disasters, determining structural (i.e. building) and behavioural (i.e. planning) risks for Maori.
