Data Journey

Contribution to OPCRD (Optimum Patient Care Research Database)

OPC services are made possible through funding sourced from ethically approved research conducted using anonymised datasets generated from the Optimum Patient Care Research Database (OPCRD).

GP practices receiving our free services contribute anonymised data to the Optimum Patient Care Research Database (OPCRD) for ethically approved scientific research into chronic diseases, helping us to further understand and improve health outcomes.

The OPCRD contains anonymised electronic medical records of over 7 million patients and supplements this with data from over 50,000 questionnaires. The clinical review data provided by OPCRD offers an essential source of real-world data to promote evidence-based research and quality improvement. The outcomes of such research are then fed back into the services provided by OPC to GP practices and CCGs.

How we use your data

Once de-identified patient data is entered into OPCRD (Optimum Patient Care Research Database) we ensure your patient population is represented in research evidence informing clinical guidance and best practice.

Below you can find some examples of how your de-identified patient data has been used in ethically approved research:

  1. Opportunities to diagnose chronic obstructive pulmonary disease in routine care in the UK: a retrospective study of a clinical cohort
  2. Predicting frequent COPD exacerbations using primary care data – OPC risk predictor models
  3. At-risk registers integrated into primary care to stop asthma crises in the UK (ARRISA-UK): study protocol for a pragmatic, cluster randomised trial with nested health economic and process evaluations
