GP-COVID daily (GPCD) - Legacy

Dataset

Documentation

Description:
The GP-COVID daily (GPCD) dataset is a legacy extract of general practice data. It contains coded clinical events recorded for patients, with the event date, a result value where applicable, and the coding version used. Patient records hold anonymised identifiers for the individual (ALF_E) and the GP practice (PRAC_CD_E), so the data can be linked to other datasets, including project-specific cohorts. Patient demographics include gender, week of birth, LSOA, registration category and an opt-out flag. The ALF match percentage and status code give the quality of the ALF matching. A practice periods table gives the start and end dates for which each practice supplied data. Time coverage may therefore vary between practices.

Access

Access Service:
The SAIL Databank is powered by the UK Secure e-Research Platform (UKSeRP). Following approval through safeguard processes, access to project-specific data within the secure environment is permitted using two-factor authentication.
Access Request Cost:
Data provision is free from SAIL. Overall project costing depends on the number of people that require access to the SAIL Gateway, the activities that SAIL needs to complete (e.g. loading non-standard datasets), data refreshes, analytical work required, disclosure control process, and special case technological requirements.
