Factors driving CT utilisation in tertiary hospitals: a decomposition analysis using linked administrative data in Western Australia.

ABSTRACT:

Objectives

While CT scanning plays a significant role in healthcare, its increasing use has raised concerns about inappropriate use. This study investigated factors driving the changing use of CT among people admitted to tertiary hospitals in Western Australia (WA).

Design and setting

A repeated cross-sectional study of CT use in WA in 2003-2005 and 2013-2015 using linked administrative heath data at the individual patient level.

Participants

A total of 2 375 787 tertiary hospital admissions of people aged 18 years or older.

Main outcome measure

Rate of CT scanning per 1000 hospital admissions.

Methods

A multivariable decomposition model was used to quantify the contribution of changes in patient characteristics and changes in the probability of having a
