NHS approved, The Health Improvement Network (THIN) is a UK‑wide repository of anonymised electronic patient records contributed voluntarily by GP practices. It provides a secure, research‑grade data set that enables academics, public‑health organisations and industry partners to examine real‑world patient pathways while guaranteeing that no personal identifiers such as names, addresses or NHS numbers are disclosed, keeping you private.
How THIN works
| 1️⃣ Data donation | Your practice voluntarily uploads routine GP data (diagnoses, prescriptions, test results, …). | It’s a voluntary contribution that fuels research that can improve future care. |
| 2️⃣ De‑identification | Automated software strips out all personal identifiers (name, DOB, NHS number, address). | Guarantees the dataset is truly anonymous—no one can trace a record back to a patient. |
| 3️⃣ Secure storage | The cleaned data are stored on encrypted servers managed by Cegedim Health Data under strict NHS‑aligned contracts. | Keeps the information safe from unauthorised access. |
| 4️⃣ Ethical clearance | Every research project must pass an ethics review and often includes patient‑representative input. | Ensures the work is responsible and patient‑centred. |
| 5️⃣ Research use | Approved researchers (academics, pharma, public‑health bodies, device makers) analyse the data to answer questions such as: • Are new drugs safe? • How do diseases spread over time? • Which treatments work best in real life? |

FAQ
Is my personal health information in THIN?
No. All identifiers are removed before any data leave the practice.
Can I withdraw my practice’s data?
Yes. Participation is voluntary and practices can opt‑out whenever they wish.
