     <p>Every month, the NHS in England publishes <a href="https://digital.nhs.uk/practice-level-prescribing-summary">anonymised data</a> about the drugs prescribed by GPs. But the raw data files are large and unwieldy, with more than 700 million rows. We're making it easier for GPs, managers and everyone to explore - supporting safer, more efficient prescribing.</p>
