Computation description:Help on this term

Adverse events are defined as incidents in which harm resulted to a person receiving health care. They include infections, falls resulting in injuries, and problems with medication and medical devices. Some adverse events may be preventable.

The current measure for this indicator can be interpreted as representing selected adverse events in health care that have resulted in, or have affected, hospital admissions, rather than all adverse events that occurred in hospitals.

A hospital separation may be recorded against more than one adverse event category as some adverse events are reported as diagnoses and others as external causes or places of occurrence (of the injury or poisoning). Some of the adverse events may represent events that occurred before admission.

Analysis by state and territory is based on location of the service.

Presented as a number per 100 separations.

Number of hospital separations with an adverse event, where an adverse event is defined as follows (using ICD-10-AM 10th edition):

Adverse effects of drugs, medicaments and biological substances Y40.~ – Y59.~
Misadventures to patients during surgical and medical care Y60.~ – Y82.~
Procedures causing abnormal reactions / complications Y83.~ – Y84.~
Other external causes of adverse events Y88.~ – Y95.~
Place of occurrence of injury and poisoning
Place of occurrence: Health service area Y92.23, Y92.24 (a separation with both codes counts as two separations with adverse events
Diagnoses
Selected post-procedural disorders E89.~, G97.~, H59.~, H95.~, I97.~, J95.~, K91.~, M96.~, N99.~
Haemorrhage and haematoma complicating a procedure T81.0

Comments:Help on this term

Most recent data available for Australian Health Performance Framework: 2017–18.

Data for 2007–08 to 2016–17 were obtained from Admitted patient care NMDSs for those years. Similar data elements were used to those listed above for the 2017–18 Admitted patient care NMDS.

From 2017–18 the specificity of Place of occurrence: Health service area has improved in that adverse events in the current or another health service area are now separately identifiable. Separations with an adverse event in both the current and another health service area are now counted as two separations with adverse events, and consequently the number and rates of separations with Place of occurrence: Health service area may have increased for 2017–18 compared with previous years.

The scope of the National Hospital Morbidity Database (NHMD) is episodes of care for admitted patients in essentially all hospitals in Australia, including public and private acute and psychiatric hospitals, free-standing day hospital facilities, alcohol and drug treatment hospitals and dental hospitals.
