Observational Study
Variability in size and characteristics of primary care networks in England: observational study.
General practices in England have been encouraged by national policy to work together on a larger scale by creating primary care networks (PCNs). Policy guidance recommended that they should serve populations of 30 000-50 000 people to perform effectively. ⋯ More than 40% of the PCNs were not of the recommended size, and there was substantial variation in their composition and characteristics. This high variability between PCNs is a risk to their future performance.
