This poster was presented at the European Forum for Primary Care annual conference, in Riga, Latvia, September 2016.
The data source is all English GP practices by list size, and the GPPES survey data for the same practices.
A clear relationship was found between the top score “Very good” and practice list size by band. Note that the critical distinction is between the score “Very good” and “Good”. The often used tactic of combining the top two scores makes the relationship disappear. However, given that 85% of respondents gave the top two, which is typical of surveys where most people are “nice” unless they have a particular complaint to make, I submit that the difference is useful.
