Breast Cancer Quality Performance Indicators

Breast cancer is the most common cancer in Aotearoa and predominantly affects women. Each year there are around 3,500 new cases in Aotearoa. While we have seen steady improvements in breast cancer survival over the last few decades, there are still barriers in access to high quality care and variations in how care is delivered and received across the motu. 

Quality Improvement Monitoring Report

The quality improvement monitoring presents QPIs that are agreed measures of good care, and primarily describes the variation in these measures between districts (previously district health boards (DHBs) prior to 1 July Health and Disability Sector Reforms).

Te Aho o Te Kahu expects districts will review their performance and, where unwarranted variation is identified, take action to improve their performance and patient outcomes. The differences noted in our findings and discussed in this report will also help guide national quality improvement programmes.

Quality Performance Indicator Descriptions

The QPI descriptions report outlines the detailed evidence-based descriptions for each indicator including the numerator and denominator. This report should be read in conjunction with the monitoring report. It includes the 10 indicators that have been measured using Te Rēhita, and those we term ‘aspirational’. Aspirational indicators are important for clinical care quality improvement and may be measured in the future, but the 10 reported on in the monitoring report have been deemed the most important for driving improvements in breast cancer care.

Quality Performance Technical Specifications

The QPI technical specifications report outlines method for calculating each QPI that is reported in the associated monitoring report. This method provides enough detail to recalculate the indicators, if required. It provides information on data sources, numerator criteria, denominator criteria, relevant data codes and descriptions and data flow diagrams.

Acknowledgements

Te Aho o Te Kahu Cancer Control Agency, would like to acknowledge Te Rēhita Mate Ūtaetae - Breast Cancer Foundation National Register, for providing the source data and working with the agency to supply technical specifications and calculations for the breast cancer quality performance indicators to help improve equity, the quality of cancer services, and outcomes for people diagnosed with breast cancer across Aotearoa. Te Aho o Te Kahu also thanks Breast Cancer Foundation NZ, as the funder of this register, for supporting this work.

National Breast Cancer Working Group

Role

Scoping the breast cancer QPI programme of work was started by the breast cancer significant interest group (SIG) in 2020. In October 2021, following completion of other QPI projects, Te Aho o Te Kahu picked up the work of the SIG and resourced the breast cancer QPI programme of work. Te Aho o Te Kahu established the National Breast Cancer Working Group (NBrWG) in February 2022, after a public call for nominations. In August-September 2022 we consulted on the draft breast cancer QPI descriptions. Following that consultation, the Agency and the NBrWG agreed to use Te Rēhita Mate Ūtaetae - Breast Cancer Foundation National Register (Te Rēhita) as the data source for the breast cancer QPIs. The Agency, the Breast Cancer Foundation National Register and the NBrCWG are currently working together to calculate and report on the 10 breast cancer QPIs that have jointly been agreed are the most important for driving improvements in breast cancer care.
