Auditing a Term of Paper Sign-In Sheets After Improvement Grand Rounds Retired Its Tap-Card System

A paper from the School of Continuous Improvement builds an in-house handwriting-divergence tool to test whether Improvement Grand Rounds' reinstated paper sign-in sheet is actually harder to fake than the tap-card system it replaced. Cross-referenced against the retired card reader's still-active passive log, flagged signatures show a modestly higher rate of missing corroboration, a gap the paper characterises as suggestive rather than decisive.
