The GP patient survey (GPPS) has been designed to give patients the opportunity to provide feedback about their experiences of their NHS GP and dentistry services across a variety of issues.
Over a whole-year cycle, about 2.1 million surveys are sent out and about 800,000 responses are received. The average response rate is 37.5%.
Respondents can respond by post, online or by phone. They may request a questionnaire in a different language, in braille or online using sign language.
Surveys collect information from a random sample of the target population to make generalisations (reach ‘findings’) about everyone within that population.
All surveys carry the risk of biased results if some types of people are less likely to respond than others. To compensate for this, data from the GP patient survey is weighted to account for this non-response bias. This adjusts the data to account for potential differences between the demographic profile of all eligible patients in a practice and the patients who actually complete the questionnaire. The non-response weighting scheme has been developed by Ipsos MORI, incorporating elements such as age and gender. It also includes factors from the area where the respondent lives, such as level of deprivation, ethnicity profile, Acorn classification, which have been shown to impact on non-response bias.
