Australian Commission on Safety and Quality in Healthcare: The cost of hospital-acquired diagnoses

23 May 2011 | Adverse Events

In 2007, the Australian Commission on Safety and Quality in Healthcare engaged the University of Queensland to learn more about the economic costs of adverse events in Australia. This work included the development of a new Australian tool to better characterise in–hospital patient illness and injury: the Classification of Hospital Acquired Diagnoses (CHADx or ‘chaddix’). CHADx is based on the validation of the grouping system to characterise the majority of in-hospital complications to assist in measurement of the economic cost of patient injury or illness. It will enable appropriate prioritisation of patient safety programs through development of a tool for monitoring the impact of patient safety interventions.

Data on patient safety performance is an important tool for use by hospitals and others in reducing the rate of hospital-acquired illness and injury. But prospective collection of such data, or even undertaking retrospective chart review, is very costly. CHADx offers a pragmatic method of quantifying the cost of unsafe and poor quality health services to admitted patients, taking advantage of the early adoption in Victoria and Queensland of the "present on admission" flag in administrative data.
