The survey was sent to a random sample of people, aged 16 and over, who had had an overnight stay in hospital in Scotland between April and September 2013.
A total of 43,893 questionnaires were sent out and 21,127 were returned, giving a response rate of 48 per cent. More information on the survey design, response rates and methodology can be found in the Technical Report.
Prior to the 2014 survey, the survey questionnaire and methodology was reviewed with input from patients and a wide range of stakeholders including NHS boards. The changes include:
- The sampling period was reduced from 12 months to 6 months. This means that the survey covers people having an overnight stay in hospital between April and September 2013. The reason for this change is to make it easier for respondents to recall their experiences by shortening the maximum length of time between their hospital stay and being surveyed.
- The sample was drawn centrally by ISD (Information Services Division, part of NHS National Services Scotland). Previously the sampling was done by NHS Boards. The main advantage of this change is that it will reduce the burden on NHS Boards.
- The questionnaire was reviewed to ensure that it is still measuring what is important to people.
