Primary Care Clinical Informatics Unit Research Data Set (PCCIU)



What data did we collect?
Details of patient encounters.
Details of Read coded diagnoses, results, problems and procedures
Details of measurements.
Details of issued prescriptions.
Date of birth (only month and year), gender and postcode to sector level (e.g. G43 2), registered clinician.
Clinician cypher, if present, for each clinician.
Limitations of data
Our data collection is reliant on the data entry systems and completeness within our contributing Practices. Some of these Practices may be 'paperlight' with more complete data entry relating to consultations. The majority will utilise a mixed system of computer and paper recording.

Prescription data and diagnosis coding for Clinical summaries is expected to be quite complete, particularly looking back over the last 10 years. In addition, from 2003, items relating to QOF will be well recorded.

Data relating to consultations and types of encounters are collected but is expected that this data may be less accurate.

We do not collect patient or clinician identifiable data, nor do we collect any free text (clinical notes).
Data Archive
We have collected clinical data from general practice for several years. Subsets of these data are available (subject to approval and by following the PCCIUR application process).
