Description
This work comprised two proposals to the Accident Compensation Corporation (ACC).
The first study was an assessment of the performance of Aotearoa New Zealand hospitals with a specific focus on injury events and ACC claims. National Minimum Data Set (NMDS) records for 2001–2009 were used to identify injury events and ACC claims, and the performance levels of different hospitals were described based on the tracking of trends over time in:
- the level of injury events overall and by type;
- the level of ACC claims overall and by type of injury; and
- adverse patient outcomes resulting from injury events and ACC claims, e.g. unplanned readmission and mortality (for which data were available through to 2007).
Each of these was also broken down by sociodemographic groups within each hospital.
The second study involved adapting existing international measures of patient safety to the Aotearoa New Zealand context, specifically relating to iatrogenic or treatment injury, covered in the ICD-10 code block Y40–Y84: Complications of medical and surgical care. We followed specifications from the United States of America via the Agency for Healthcare Research and Quality (AHRQ) and from Australia via the Department of Health in the State Government of Victoria, and adapted them based on what was covered by the ACC.
The resulting indicators were again used to describe variation among hospitals and different sociodemographic groups.
