Why Most Readmission Models Never Reduce Readmissions
A readmission prediction model can validate beautifully and still prevent almost nothing. One equation shows where the readmissions you hoped to avoid actually…

Clinical AI succeeds or fails on arithmetic that is easy to state and easy to ignore: at low prevalence, even an accurate model produces mostly false alarms, and a care program that enrolls the sickest patients can look like it fails when it works. Vector 1 builds early-warning, capacity and program-evaluation models with those tradeoffs on the table.

Because the conditions they detect are rare. When 2% of patients have a condition, even a model with high accuracy flags many more patients without it than with it, so most alerts are false. Alert thresholds should be chosen with nurse time and missed cases in view.
Compare enrolled patients with similar patients who weren't enrolled, adjusting for the risk factors that drove enrollment. Programs usually enroll the highest-risk patients, so a raw comparison makes a working program look ineffective.
