Real world data—retrieval and validation of consultation data from four general practices

Real world data--retrieval and validation of consultation data from four general practices.

OBJECTIVE We aimed to retrieve data on consultations from general practice databases and to develop and use appropriate methods of validation for these data. METHOD MIQUEST software was used to retrieve the data from four practices. The data were validated by comparing them with figures generated by practice-based searches, measuring the uptake of recording of consultations over time, and com...
