About the data
The performance at a Glance section of Our Hospitals and Health Services presents information on public hospitals and contracted health entities throughout Western Australia (WA) and how they compare against National Targets (where possible) including: waiting times for emergency departments and elective surgery, mental health, safety and quality, patient satisfaction and finance.
The content in this section is based on available information recorded in a range of data management collection systems, such as the Emergency Department Data Collection (EDDC) and Hospital Morbidity Data Collection (HMDC) systems.
Data are not available for all hospitals, in particular small hospitals and those in remote areas.
Caution should be exercised if comparing data, as hospital activity varies between sites.
As part of an ongoing quality improvement process, data displayed is subject to change to ensure the most accurate data is presented.
1. Emergency Department (ED)
Waiting times provide an indication of access to emergency services. This section presents two measures for each hospital with emergency services:
Emergency department waiting times - the percentage of patients seen within recommended times within a given triage category compared to the National Target (target source: the Australasian College for Emergency Medicine).
- WA Emergency Access Targets (WEAT) - the percentage of ED patients seen within 4 hours.
- Re-attendances to ED - the re-attendances to the ED within 48 hours indicator has been removed from reporting as the data is under review for quality improvement. This indicator will be reported again once the review is completed.
2. Elective Surgery
Waiting times provide an indication of access to elective surgery. This page presents the following measures for each hospital that provides information on elective surgery admissions from its elective surgery waiting list:
- WA Elective Services Target (WEST) Performance: the percentage of elective surgery patients on the waiting list longer than the clinically recommended times according to their urgency category (Target=0%).
- Selected elective cancer surgery cases (lung, bowel, breast and prostate cancer) - the percentage of elective lung, bowel, breast and prostate cancer surgery cases which were treated within the recommended time.
3. Safety and Quality
WA Health is committed to improving the safety and quality of care in hospital. The Our Hospitals and Health Services website supports this goal by making the following safety and quality information available for individual hospitals:
Healthcare - associated Staphylococcus aureus bacteraemia (HA-SAB) infection - SAB infection is a serious bloodstream infection (sometimes called 'golden staph') that may be associated with hospital care. The aim is to have a few cases of HA-SAB infection as possible. One of the most effective ways to minimise the risk of HA-SAB infection and other healthcare associated infections is good hand hygiene.
This page presents the rate of SAB infections for the reported time period expressed as the number of cases of SAB per 10,000 occupied bed days.
The most recent four quarters of SAB infection statistics will be provided.
- Hand Hygiene this indicator has been removed from reporting on this page as the data is available at:
Further information about health care safety and quality is available from the Australian Commission on Safety and Quality in Health Care http://www.safetyandquality.gov.au and Hand Hygiene Australia http://www.hha.org.au/forconsumers.aspx.
4. Mental Health
WA Mental health inpatient services aim to provide treatment that, where appropriate, enables individuals to return to the community as soon as possible. This page presents one measure for each hospital with an acute designated mental health inpatient unit.
- Mental Health Readmissions within 28 days - the rate of total hospital readmissions within 28 days to an acute designated mental health inpatient unit. This indicator is reported at the facility at which the initial admission occurred rather than the facility at which the patient was readmitted. (target source: Fourth National Mental Health Plan. AHMAC National Mental Health Performance subcommittee).
While multiple hospital admissions over a lifetime may be necessary for someone with ongoing illness, a high proportion of unplanned readmissions shortly after discharge may indicate that inpatient treatment was either incomplete or ineffective, or that follow-up care was inadequate to maintain the person out of hospital.
5. Patient Satisfaction
The overall patient satisfaction score is one component of the Patient Evaluation of Health Services survey conducted annually by Edith Cowan University's Survey Research Centre using Computer Assisted Telephone Interview. It gives an indication of overall patient satisfaction with inpatient (admitted) and outpatient (non-admitted) hospital services. This page presents the following measures for surveyed hospitals:
- Adult inpatients' satisfaction - displays the annual score for overall adult inpatients' satisfaction with hospital services. It is a measure of overall patient satisfaction of adults admitted to public hospitals, Joondalup Health Campus, Peel Health Campus and SJOG Midland Public Hospital.
- Adult outpatients' satisfaction - displays the annual score for overall adult outpatients' satisfaction with hospital services. It is a measure of overall patient satisfaction of adults visited an outpatient clinic at Armadale Hospital, Bentley Hospital, Fiona Stanley Hospital, Fremantle Hospital, Joondalup Health Campus, King Edward Memorial Hospital, Osborne Park Hospital, Rockingham Hospital, Royal Perth Hospital, SJOG Midland Public Hospital and Sir Charles Gairdner Hospital.
- Paediatric inpatients' satisfaction - displays the annual score for paediatric inpatients' satisfaction with hospital services. It is a measure of overall patient satisfaction of children admitted to Albany Hospital, Armadale Hospital, Broome Hospital, Bunbury Hospital, Derby Hospital, Esperance Hospital, Fiona Stanley Hospital, Geraldton Hospital, Hedland Hospital, Joondalup Health Campus, Kalgoorlie Hospital, Kununurra Hospital, Nickol Bay Hospital, Peel Health Campus, Princess Margaret Hospital, Rockingham Hospital and SJOG Midland Public Hospital.
- Paediatric outpatients' satisfaction - displays the annual score for paediatric outpatients' satisfaction with hospital services. It is a measure of overall patient satisfaction of children visited an outpatient clinic at Princess Margaret Hospital.
6. Finance Activity
Health expenditure accounts for more than a quarter of general state government sector expenditure; WA Health closely monitors how ongoing expenditure and activity is tracking against budgeted targets.
- Year to Date (YTD) expenditure to budget - the distance of financial YTD actual expenditure to the YTD budget. Actual expenditure is operating/recurrent expenditure, including asset investment program (capital works) expenditure.
- YTD variance of weighted activity to budget - this indicator measures the total percentage difference between weighted activity and targets across inpatients, emergency department and outpatients. For costing purposes, public hospital activity (such as inpatient activity, ED attendance and outpatient services) are weighted by complexity and converted to standard units.
To ensure data is accurate, routine data quality checks are conducted by the hospitals and the Department of Health.
