Background: Value-based healthcare (VBH) focuses on improving patient health outcomes while reducing overall cost of healthcare. The value in VBH depends upon the best patient outcome after treatment. Currently, treatment success is primarily measured by short-term clinical outcomes rather than with long-term patient-oriented outcomes. The International Consortium for Health Outcomes Measurement (ICHOM), an organization comprising of leading health experts and patient-oriented stakeholders, has recently developed a number of standardized datasets to measure both clinical and patient-oriented VBH outcomes in diseases such as breast cancer. Aim: The aim of this pilot study is to develop an implementation protocol for the ICHOM-based breast cancer standardised dataset to measure meaningful value-based outcomes within the St John of God Subiaco Hospital, a private hospital in Western Australia. Methods: Implementation of ICHOM’s breast cancer-specific standardized dataset will be rolled out in four stages: 1) engaging hospital- and patient-based stakeholders with implementation, 2) establishing a data-capture model allowing routine and efficient data collection, 3) measuring and analysing the captured data and 4) using this newly-acquired data to determine treatments which promote best patient outcomes. Results: While data are currently collected using both electronic- and paper-based formats, final data capture electronically allows for efficient data storage, frequent measurement and analysis of treatment outcomes and rapid feedback for data dissemination. Conclusion: The results of this pilot study will allow for a proof-of-concept VBH protocol to be rolled out to various breast cancer oncology units within St John of God Healthcare. This will allow continual monitoring and implementation of leading treatments which improve outcomes for patients diagnosed with breast cancer.
