Avoidable hospital readmissions

Definition of 'hospital readmission'

A hospital readmission occurs when a patient has been discharged from hospital and is admitted again within a certain time interval.

Generally, hospital readmissions can be considered in two broad categories:

• Readmissions that relate to routine care, for example those that relate to necessary treatments such as chemotherapy or dialysis, and are required to ensure safe clinical care.
• Readmissions that are potentially avoidable.

Reducing avoidable hospital readmissions supports better health outcomes, improves patient safety and leads to greater efficiency in the health system.

Definition of 'avoidable hospital readmissions'

During 2019, the Commission held a roundtable to provide advice towards establishing a nationally consistent definition. The roundtable comprised of jurisdictional representatives, technical experts and clinical experts from the public and private sectors. The definition was finalised, and agreed to, in early 2022.

An avoidable hospital readmission occurs when a patient has been discharged from hospital (index admission) and has a subsequent unplanned admission that is related to the index admission and was potentially preventable.

List of conditions considered to be avoidable hospital readmissions

The Commission was tasked with developing a list of avoidable hospital readmissions to inform safety and quality reforms in Australia.

The Commission worked with the Independent Hospital Pricing Authority to finalise specifications for the list.

Publication, report or update

The Commission has also developed and maintains, four condition specific unplanned readmission indicators, as part of the Core Hospital-based Outcome Indicators (CHBOI) toolkit.

The following is the list of conditions considered to be avoidable hospital readmissions and associated condition-specific time intervals. The list was developed by the Commission and has been agreed by the Australian Health Ministers’ Advisory Council.

The National Health Reform Agreement Addendum reforms

All Australian governments have committed to reforms under the National Health Reform Agreement Addendum, which include a focus on avoidable hospital readmissions. These reforms aim to integrate safety and quality into the pricing and funding of Australian public hospitals in a way that:

• Improves patient outcomes
• Provides an incentive in the system to provide the right care, in the right place, at the right time
• Decreases avoidable demand for public hospital services
• Signals to the health system the need to reduce instances of preventable poor quality patient care, while supporting improvements in data quality and information available to inform clinicians’ practice.

The reforms focus on reducing avoidable hospital readmissions as well as sentinel events and hospital-acquired complications.

Development of the avoidable hospital readmissions list

At the request of the Australian Health Ministers’ Advisory Council, and in line with the National Health Reform Agreement Addendum, the Commission developed the list of conditions considered to be avoidable hospital readmissions.

This list of conditions, and the related condition-specific time intervals, was developed in consultation with clinical and consumer experts, taking into consideration:

• Literature on avoidable hospital readmissions
• Australian public hospital data, through analysis of the admitted patient care national minimum data set.

Review

The AHRs list and specifications are reviewed regularly. To provide feedback on the AHRs list, please email indicators@safetyandquality.gov.au. Feedback will be considered by the Clinical Advisory Group as part of future reviews.

Version 1 of the AHR list was released in June 2019, with the update to ICD-10-AM 12th edition in May 2022.

Version 1 will be used by the Independent Hospital Pricing Authority from 1 July 2022.
