Toward A Population-Based Approach to End-Of-Life Care Surveillance in Canada: Initial Efforts and Lessons
Bibliographic record
Abstract
This paper describes a project undertaken by the Hospice Palliative End-of-Life Care Surveillance Team Network--one of four Cancer Surveillance and Epidemiology Networks established by the Canadian Partnership Against Cancer in 2009 to create information products that can be used to inform cancer control. The project was designed to improve the quality and use of existing electronic patient databases in its member organizations. The project's intent was to better understand terminally ill cancer patients in their final year of life, with noncancer as comparison. The network created an early design for a Web-based end-of-life care surveillance system prototype. Using a flagging process, anonymized data sets on cancer/ noncancer palliative patients and those who died in 2008-2009 were extracted and analyzed. The Australian palliative approach was adapted as the conceptual model based on the data sets available. Common data elements were defined then mapped to local data sets to create a common data set. Information products were created as online reports. Throughout the project, members were engaged in knowledge translation. Overall, the project was well received by network members. There are still major data-quality and linkage issues that require further work.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
