Case Study: Lewisham Hospital NHS Trust achieves a single patient view with DQ Global Match™

Lewisham Hospital NHS Trust finds 16,000 duplicates in under an hour with DQ Global

Lewisham Hospital NHS Trust faced a significant challenge with fragmented and duplicate patient records. This posed a clinical risk, as newly-admitted patients were not always correctly identified as having an existing medical record. Manually screening approximately 150 new patient registrations daily against a database of 930,000 records was a time-consuming process that had created a six-month backlog. To overcome this, the Trust worked with vendor DQ Global and implemented its Match™ data quality solution.

By using DQ Global's Match™, the hospital could identify and merge duplicate records with speed and accuracy. The solution screened the entire database of 930,000 records and found 16,000 duplicates in under an hour. Daily, the system now identifies 10-15 duplicate records, leading to over 4,000 patient records being correctly merged each year. This has eliminated the backlog, ensured data integrity, and guaranteed that clinical teams have a complete patient history for appropriate treatment.
