Case Study: Wadhwani Institute for Artificial Intelligence achieves fast, accurate COVID-19 patient matching with WinPure

Winpure Data Matching Used in Ground Breaking Covid-19 Tracker Project

The Wadhwani Institute for Artificial Intelligence (Wadhwani AI) developed the “Cough against Covid” smartphone screening tool to triage potential COVID-19 cases, but faced a data-quality challenge: three growing, separately collected datasets (patient registrations, cough sounds and COVID test results) contained typos, missing fields and inconsistent identifiers that prevented reliable linking. Wadhwani AI needed an on‑premise, automated data‑matching and cleansing solution — and evaluated vendors including WinPure.

WinPure was chosen for its on‑premise data quality software and best‑in‑class matching capabilities. WinPure’s matching and cleansing tools were deployed to deduplicate and link records across the three datasets, creating a single source of truth with faster, more accurate patient linkage, reduced manual reconciliation and improved matching results. By using WinPure, Wadhwani AI could confidently connect cough samples to test outcomes and better target scarce testing resources.
