Abstract

INTRODUCTION: Safety net hospitals (SNHs) care for a substantial population of vulnerable patients and are often resource-limited. These limitations may impact treatment decisions for high-risk prostate cancer (hPCa). We performed the first population-based analysis examining SNH status and treatment decisions for localized hPCa. METHODS: percentile of Medicaid and uninsured caseload. Non-curative-intent treatment was defined as androgen deprivation monotherapy (ADT) or no treatment. Outcomes assessed were treatment choice and overall survival (OS) by SNH status. RESULTS: A total of 95 747 patients with hPCa were included; 112 hospitals were identified as SNHs, with mean Medicaid/uninsured caseload of 24.4% compared to 3.2% at non-SNHs (p<0.01). Patients at SNHs were independently associated with greater odds of non-curative-intent treatment (odds ratio [OR] 2.2, p<0.01). Results were consistent across subgroups: private insurance (OR 2.2, p<0.01), age <65 (OR 2.3, p<0.01), and at academic centers (OR 1.9, p<0.01). There was no difference in OS among SNHs and non-SNHs when patients received curative treatment. Among patients who did not receive curative treatment, OS was greater at SNHs (hazard ratio 0.82, p=0.02). CONCLUSIONS: Patients at SNHs were more likely to receive non-curative treatment independent of known socioeconomic risk factors. Private insurance or treatment at academic centers did not mitigate these disparities. Increased resources may be needed at SNHs, especially in the context of healthcare expansion, which may further strain these facilities.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
