The Cancer Registry of Norway (CRN) collects data about cancer patients, e.g., about diagnostic, treatment, and follow-up, and provide this data and statistics to its end users, e.g., researchers, patients, doctors, and health authorities. Decisions, regarding how this data should be coded rely on a semi-automated and interactive decision support system, named as Cancer Registration Support System (CaReSS). The system uses a patient’s test results and treatments, and makes decisions, based on medical coding rules, often using machine learning. CaReSS evolves due to, e.g., addition, deletion, and modification of rules due to new treatments, improved diagnostics, new medical results and tests, and new diagnostic standards. Also, CRN continuously updates CaReSS with advanced versions of machine learning algorithms. Thus, the implementation of CaReSS undergoes continuous change and warrants continuous, cost-effective testing of CaReSS as it evolves. A well-test CaReSS will prevent the system from producing inaccurate statistics and data to its end users. Inaccurate or imprecise data produced by CaReSS have significant adverse effects on the scientific results produced by researchers. Also, inaccurate or imprecise statistics produced by the CaReSS will significantly impact the decisions made by patients, hospitals, and policymakers. The innovation planned is a state-of-the-art test infrastructure including new testing techniques to support cost-effective and systematic testing of the CaReSS to significantly improve its quality, and quality of data and statistics it produces, by dealing with the continuous evolution and unpredictable behavior of machine learning algorithms. This will positively affect all its end users, including researchers, patients, doctors, and government officials. The deployment of the new testing infrastructure at CRN will lead to significant improvements in the current testing practice at CRN.
