AHPF PI 2.1.4–Selected potentially preventable hospitalisations, 2019

Synonymous names:

Selected potentially preventable hospitalisations

METeOR identifier:

715161

Registration status:

Health, Standardisation pending 03/12/2019

Description:

Admission to hospital for a condition where the hospitalisation could have potentially been prevented through the provision of appropriate individualised preventative health interventions and early disease management usually delivered in primary care and community-based care settings (including by general practitioners, medical specialists, dentists, nurses and allied health professionals).

For example, hospitalisations for conditions such as measles and tetanus can be prevented by primary health care through vaccination to prevent the conditions from occurring. Hospitalisations for patients presenting with acute pharyngitis can be prevented through timely treatment in primary health care settings using antibiotics, and hospitalisations for diabetes complications can be prevented through appropriate, long-term management of diabetes by primary and community health practitioners.

The above definition excludes conditions that are preventable predominately through population health interventions, such as those for clean air and water.

Comments:

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

The scope of the National Hospital Morbidity Database 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.

For 2017-18 data, the SEIFA IRSD quintiles and deciles used are 2016 SEIFA IRSD quintiles and deciles derived using the Australian Statistical Geography Standard (ASGS) 2016 geographical unit of Statistical Area Level 2.
