OPCRD can access data from a wide range of sources, allowing for collection of data to satisfy bespoke data requirements. This includes:

National Prescribing Data

OPC has access to nationwide practice prescribing data to enable targeted service delivery such that dataset requirements can be swiftly delivered following product launch. OPC appreciates the importance of timely marketing campaigns and continues to deliver post launch marketing studies at unrivalled speeds.

Electronic Medical Records (EMR)

The unique nature of the UK’s NHS allows the life-long health record of a UK citizen to be held by one practice. OPCRD provides a comprehensive picture of over 6.3 million anonymous patient data including:

  • Demographic information
  • Diagnoses
  • Symptoms
  • Treatments and prescriptions issued
  • Test results and measurements and results taken in the practice
  • Referrals

Questionnaire Data

OPC questionnaires are a compilation of validated clinically relevant questions covering symptoms, disease control, triggers, side effects, quality of life, and adherence measures. The questionnaires can be distributed to patients from their GP practice as part of OPC clinical review services. OPCRD currently holds questionnaire data in respiratory (adult asthma, child asthma and COPD) covering 50,000 patients:

  • Symptoms
  • Smoking status
  • Allergies
  • Adherence
  • Patient preferences/beliefs/concerns
  • Side effects
  • Quality of life

Clinical Review Data

OPC’s clinical services allow bespoke opportunities to conduct data collection as part of standard clinical practice. OPC have been delivering clinical reviews to over 5,000 respiratory patients, enabling OPCRD to hold unique and enhanced data in respiratory:

  • Patient symptoms
  • Therapy concordance
  • Side effects
  • Disease impact
  • Lung function
  • Fractional Exhaled Nitric Oxide (FeNO)
  • Basic spirometry
  • Inhaler technique assessment and training

Secondary Care

OPCRD primary care data can be linked to secondary care and other data sets. This linkage enables OPCRD to provide a fuller picture of the patient care record to support vital public health research, informing advances in patient safety and delivery of care.

National Registries

Linking routine electronic medical record (EMR) data with clinical registry data provides a more complete picture of the patient journey through episodes of care. OPCRD EMR data can be linked to existing and new registries, some active examples include:

  • International Severe Asthma Registry (ISAR)
  • International Helping Asthma in Real-life Patients (iHARP)
  • Death Registration data from the Office for National Statistics (ONS)
  • Deprivation data: Townsend Scores/Index of Multiple Deprivation (IMD)
  • NHS High Cost/IFR database (BLUETEQ)

Further details are available upon request.

Clinical Trials/Intervention Programs

Following a new strategy or intervention being introduced into GP practices, OPC can use prospectively collected EMR data as captured within routine clinical practice to assess outcomes. This provides reduced operational demands, patient burden and costs as compared to classical randomised controlled trials (RCT’s). Furthermore, by keeping data collection protocols to routine care, the trials are more reflective of the real world.
