Trend in CT utilisation and its impact on length of stay, readmission and hospital mortality in Western Australia tertiary hospitals: an analysis of linked administrative data 2003-2015.

ABSTRACT:

Objective

High use of CT scanning has raised concern due to the potential ionising radiation exposure. This study examined trends of CT during admission to tertiary hospitals and its associations with length of stay (LOS), readmission and mortality.

Design

Retrospective observational study from 2003 to 2015.

Setting

West Australian linked administrative records at individual level.

Participants

2 375 787 episodes of tertiary hospital admission in adults aged 18+ years.

Main outcome measures

LOS, 30-day readmissions and mortality stratified by CT use status (any, multiple (CTs to multiple areas during episode), and repeat (repeated CT to the same area)).

Methods

Multivariable regression models were used to calculate adjusted rate of CT use status.
