Patterns of computed tomography utilisation in injury management: latent classes approach using linked administrative data in Western Australia.

ABSTRACT:

Purpose

Whilst computed tomography (CT) imaging has been a vital component of injury management, its increasing use has raised concern regarding ionising radiation exposure. This study aims to identify latent classes (underlying patterns) of CT use over a 3-year period following the incidence of injury and factors predicting the observed patterns.

Method

A retrospective observational cohort study was conducted in 21,544 individuals aged 18 + years presenting to emergency departments (ED) of four tertiary public hospitals with new injury in Western Australia. Mixture modelling approach was used to identify latent classes of CT use over a 3-year period post injury.

Results

Amongst injured people with at least one CT scan, three latent classes of CT use were identified i
