70% of healthcare AI models never reach production
Hospital AI passes offline validation with clean test sets, then breaks on real patients. Models don't see missing data, workflow chaos, or population shifts until it's too late—and too expensive to fix.
The Missing Data Problem
Clean test sets hide the reality: production EHRs lose 30%+ labs, hit delayed vitals, and have patchy notes. Models trained on pristine data stumble on live patients.
The Workflow Chaos Problem
Offline validation ignores EHR upgrades, documentation slip-ups, sensor drift, and midnight staffing. Hospitals are chaotic, constantly changing, and anything but static CSVs.
The Population Shift Problem
ICU populations and physiology drift weekly, so last year’s validation cohort doesn’t mirror today’s patients. Silent failures emerge as unseen subpopulations and new disease patterns hit production.
Where Krv Fits in Clinical AI Validation
Current evaluation approaches are complex and time-consuming. We streamline the R2P lifecycle with targeted testing that finds failure modes before production.
Stress-Test Models Before They Touch Patients
We run your model through thousands of realistic clinical scenarios—missing data, workflow chaos, edge cases—to find failure modes before production deployment.
Generalizability
We stress-test your model on age groups, ethnicities, and comorbidity combinations it's never seen. If it fails on a 25-year-old after training on seniors, you'll know before deployment.
Stability
Does a 1-point sodium shift (139→140) flip the diagnosis? We test clinically identical patients—like monozygotic twins—to ensure consistent risk scores and catch numerical instability.
Sanity
We inject impossible data (Heart Rate 600, Potassium 15, male pregnancy) and logic errors to verify your model catches nonsense instead of amplifying it.
Resilience
Can your model handle 30% missing labs or 2-hour vital delays? We simulate EHR outages, sensor drift, and staffing constraints to ensure graceful degradation.
Krv Platform vs. Shadow Mode
Shadow mode finds problems after 12 months on live patients. We find them in weeks—before deployment.
5 Weeks, Not 12 Months
Shadow mode runs live models for a year. We simulate thousands of messy clinical scenarios in weeks so you catch edge cases, missing data, and drift before deployment.
Exact Failure Modes, Not AUROC Scores
Shadow mode goes beyond aggregate scores. It pinpoints failures—'30% missing labs cuts sensitivity 40%' or 'Asian, 65+ drift'—so you fix them before going live.
Prevent Bad Deployments
Epic’s sepsis model succeeded on paper (76-83%) but caught 33% in practice. Shadow mode would have caught that before a single patient was exposed.
Would You Deploy an Untested Model?
Not even close. Your test set has 0% missing data. Production EHRs have 30%+ missing labs. Your test set is balanced across demographics. Production ICU patients cluster in ways you didn't train for. Your test set is static. Production involves EHR upgrades, sensor drift, and documentation errors. AUROC tells you aggregate performance on clean data. We tell you exactly when your model breaks: '30% missing labs drops sensitivity to 60%' or 'Asian patients age 65+ trigger miscalibration.' You need both. We provide the second.
