Title | Clinical Practice Research Datalink |

Description | CPRD is a database capturing inpatient and outpatient claims from the United Kingdom’s National Health Service. The online database, also called CPRD GOLD, contains patient registration information and all care events that general practitioners (GPs) have chosen to record in a singular EHR database as part of their usual medical practice. Information held includes records of clinical events (medical diagnoses), referrals to specialists and secondary care settings, prescriptions issued in primary care, records of immunizations/vaccinations, diagnostic testing, lifestyle information (e.g. smoking and alcohol status), and all other types of care administered as part of routine GP practice. Data in the online system are enhanced by the addition of central mortality data (date and causes of death) as well as certain key data from Hospital Episode Statistics (HES- hospitalized patients). Pharmacy claims are also linked to the inpatient and outpatient data. Finally, the following consented data may be available for some patients: clinical trial information, bio-samples, and patient reported outcomes. Data is collected through electronic health records and encompasses over 64 million patients and more than 25 years. The primary care population in CRPD is expected to grow over time. The database contains an open cohort for both practices and patients. All data is linked to patients and physicians so additional information to confirm diagnoses or conduct surveys is possible. Data is indexed based on NHS number, which reduces the likelihood of duplicates in the system. |
