Every year the NHS commissions the reputable pollster IPSOS-MORI to conduct a survey of patient experience at GP surgeries throughout England. There are about 50 questions in the survey and the pollsters try to get a good number of people at each surgery to complete the survey. We now have results for many years.
The problem lies in how to interpret the results. If 90% of patients surveyed think that their surgery is good or very good - is that a good result? Put another way if 10% of patients say their survey is not good - is that good enough?
