APHID: Are 'potentially preventable hospitalisations' a valid inDicator of the quality and affordability of primary and community care in Australia?
Rates of potentially preventable hospitalisations (PPH) are regarded as an indicator of the quality and affordability of primary and community care. They are increasingly being used to track the progress of health reform in Australia and internationally. This project validated PPH as a measure of health system performance in Australia. Using linked person-level data, we explored relationships between frequency, volume, nature and costs of primary care services; hospital admissions for PPH diagnoses; health outcomes; and factors that confound and mediate these relationships. Using multilevel modelling techniques we quantified the contributions of person-, geographic- and service-level factors to variation in PPH rates, including socio-economic status, country of birth, geographic remoteness, physical and mental health status, availability of general practitioner (GP) and other services, and hospital characteristics.
Outcome and Translation
Our findings will inform the ongoing use of PPH to track the progress of health reform in Australia and internationally.
