Abstract
INTRODUCTION: Chronic kidney disease (CKD) progression is associated with a significant incremental economic burden. Previous work has demonstrated high accuracy of the laboratory-based machine learning model, Klinrisk, in predicting the risk of CKD progression. We sought to use the Klinrisk model to evaluate the association of risk of CKD progression with healthcare resource utilization (HRU) and costs of care in adults with type 2 diabetes and CKD. METHODS: This retrospective observational study included 413,177 eligible patients from Optum's electronic health records database (1/1/2007-9/30/2022). Patients were classified into low-, medium-, and high-risk groups based on their 2-year risk of CKD progression as predicted by the Klinrisk model. All-cause HRU and medical costs during the 1 year after CKD were estimated for each group. RESULTS: Of the 413,177 patients included, 110,399 (26.7%) were classified as low-risk of CKD progression, 253,188 (61.3%) as medium-risk, and 49,590 (12.0%) as high-risk. The observed risk of CKD progression at 2 years, 5 years, and 10 years was 18.6%, 36.5%, and 54.1% for high-risk patients, 3.7%, 11.7%, and 26.4% for medium-risk patients, and 1.5%, 5.7%, and 15.8% for low-risk patients, which were similar to the predicted risks of CKD progression. High-risk patients had higher HRU and more than 2-3 times higher costs than lower-risk patients. Inpatient costs were the major cost driver for high-risk patients. CONCLUSIONS: The Klinrisk model accurately identified patients with type 2 diabetes and CKD requiring the most healthcare resources. Such tools can support the identification and targeting of high-risk patients for interventions that may lead to a more cost-effective model of care.

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 it
