This document discusses the need for the General Practice Data for Planning and Research (GPDPR) Programme in England. It notes that England's NHS faces challenges from an aging population with rising long-term conditions. Good primary care data on the health and healthcare use of the population is essential for NHS planning, public health surveillance, and research. However, concerns have been raised about the GPDPR regarding a lack of publicity about opting out and potential confidentiality issues if too many people opt out. Building public trust will be important for the success of the program.
