Exemptions

Some uses of data, such as conducting analyses for submissions to regulatory bodies, are exempt from ISAC review. 

Analysis for regulatory bodies 

In general, ISAC approval is required prior to release of CPRD data to any third party, so as to ensure that the standard of studies carried out using CPRD data is maintained. However, there are some types of aggregate data necessary for regulatory work that is suitable for exemption from this requirement, such as:

  • Counts of patients receiving prescriptions for a certain substance;
  • Counts of prescriptions for a certain substance / substances;
  • Distribution of number of prescriptions per patient (mean, median, minimum, maximum, interquartile range etc…);
  • Distribution of prescription duration;
  • Distribution of patient time at risk;
  • Counts of patients with a particular clinical event.
