Brief summary

Around 1,200 addresses will be identified in the Wellington Region and New Plymouth where there are more than 5 access steps and neither handrails nor step edgings (nosings). From these, 400 addresses will be randomly sampled to receive modifications at no cost to the occupants or owners. The modifications will consist of the provision of handrails and step edgings and minor step repairs where necessary. An address match for the treatment group homes and the control homes in the same area will then be conducted by the national injury insurer, ACC, to identify falls in the home that received ACC-funded medical treatment over the period before modification and after modification of the addresses in the study. Analysis will then be conducted on anonymised counts identified only by the general location, age group and sex of the injured people, and a random digit per address to identify falls happening at the same address (so that clustering by household can be accommodated in the analysis). The main analysis will be according to “Intention to Treat” principles, where injury rates for all homes allocated to the treatment group are compared to the controls. A secondary analysis will consider the safety benefits only for homes that consented to have the modifications done.

Interventions

Installation of safety features on access steps to home. These consist of handrails and step edgings (where possible) that are slip-resistant and high-visibility. The outcomes will be assessed based on an anonymised address match, so as long as addresses of injured people are recorded correctly, the exposures will be appropriately assigned during analysis.
