AIHW - Indigenous Eye Health Measures - Hospitalisation Rates for Cataract Surgery (PHN) 2014-2016

This dataset presents the footprint of the rate of hospitalisations with a procedure for cataract surgery per 1,000,000 Indigenous population by client location. The location of the client is based on their place of usual residence. The data spans the financial years between 2014-2016 and is aggregated to 2015 Department of Health Primary Health Network (PHN) areas, based on the 2011 Australian Statistical Geography Standard (ASGS). The data is sourced from the Australian Institute of Health and Welfare (AIHW) - National Hospital Morbidity Database (NHMD), which is a compilation of episode-level records from admitted patient care data collection systems in Australian hospitals in each state and territory. The NHMD is based on data provided to the AIHW by state and territory health authorities for the National minimum data set (NMDS) for Admitted patient care.

AURIN has spatially enabled the original data using the Department of Health - PHN Areas.

The data are crude rates.

Data by PHN should be interpreted with caution due to variations in admission practices, and because patients may be hospitalised outside the PHN where they reside.

Almost all (96%) cataract surgery in Australia is undertaken on a same-day basis. The data may underestimate the number of procedures provided as they do not include those undertaken on an outpatient basis.

The quality of data provided for Indigenous status varies. Time-series analyses may also be affected by changes in the quality of Indigenous identification over time.
