Carl Booth, MPhil BPharm MRPharmS, of Airedale NHS Foundation Trust, Keighley, UK, talks to us about collaboration amongst pharmacists to enable them to collect treatment data on a much larger scale. Collecting results from a larger sample will allow for a better understanding of how drugs impact patients in the real world compared to a clinical trial setting. This video was recorded at the British Oncology Pharmacy Association (BOPA) 20th Annual Symposium 2017 in Glasgow, UK.
