  2. Trusted Data linkage Service • Data • HES, PROMS, ONS, MHMDS, Cancer • Customers • Universities, NHS, research, government, commercial • DCLG – Homelessness • The Nuffield Trust – Person based resource allocation • Dept. for Transport – STATS19 • IMS – Hospital prescribing data • GPRD, CSDMR, QResearch – GP data linkage

  3. Linkage algorithms • Fields used: • NHS number • Date of birth • Sex • Postcode • (Names)

  4. Deterministic vs. probabilistic • Probabilistic • Very processor intensive – HESID index availability • Expensive • Useful when things are similar • NHS numbers are exact • Deterministic • Efficient • Cheaper • Less accurate? • Algorithm accounts for most common keying error
