Health and Care Experience Survey 2017/18: National Results

The results for the 2017/18 Health and Care Experience Survey were published last week. This was the fifth iteration of this survey. It asked people about their experiences of accessing and using their GP practice and other local healthcare services; receiving care, support and help with everyday living; and caring responsibilities.

The results showed that most GP patients and social care users reported a positive experience of their care. However, respondents were slightly less positive than in previous surveys, in particular about accessing GP services and support for carers. A copy of the full report is available at www.gov.scot/ISBN/9781788517669.

This blog post looks at some of the changes that were made to the 2017/18 survey and what the impacts of these changes have been.

Boosting Response Rates

To ensure reasonably reliable results at GP practice level across Scotland, the size of the sample drawn for the survey has to be very large. The size of the sample required is calculated based on the minimum sample size required per GP practice and includes an adjustment for estimated response rates.

Like many surveys of this type, both in Scotland and elsewhere, there has been a fall in response rates since this survey was begun. This continuing drop in response rates has caused the sample size required to increase (Table 1). Even after allowing for the reintroduction of a reminder letter to the 2017/18 survey, it was still calculated that over 600,000 people would need to be sampled to achieve the required levels of response.

Ahead of the survey going live, a number of changes were made to try and improve engagement with respondents and help to boost response rates:

  • survey materials were reviewed and improvements made to the style and layout to make them more engaging and user friendly;
  • the content of the questionnaire was reviewed to ensure continued relevance, allowing the length of the questionnaire to be reduced from 12 pages to 8;
  • changing the mailout strategy to increase online responses by:
    • online including information on online and helpline survey completion methods in the initial mailout (no paper questionnaire was provided);
    • introducing a reminder letter which contained a paper questionnaire.

This combination of changes appear to have had a positive impact on response to the survey, with the response rate six percentage points higher than in 2015/16.

The attempts to increase online response also saw significant success, with 40 per cent of survey responses completed online compared to ten per cent in 2015/16.

Copies of all of the survey materials can be found at www.gov.scot/GPSurvey.

Data Protection Compliance

The content and wording of the survey materials were reviewed ahead of fieldwork to ensure that they were compliant with the General Data Protection Regulations that will be coming into force on 25th May. This also included the introduction of a Privacy Notice for the survey which was highlighted to respondents within the survey letter. The Privacy Notice is available at www.gov.scot/HACEPrivacyNotice.

Changes to Analysis and Reporting of Results

As there was a significant increase in online responses for the 2017/18 survey, improvements were made to the validation of the results to ensure comparability between online and paper returns.

A review of the weighting methodology was undertaken in advance of the 2017/18 survey, leading to some changes in the weights applied. Results at all levels of the 2017/18 reporting are weighted. Results at GP Practice level are also presented unweighted. Details of the review, the full methodology applied to the 2017/18 results and the impacts of the change are available at www.gov.scot/Resource/0053/00533823.pdf.

Figures from previous surveys included in all 2017/18 reports and files have been backdated to use the improved validation checks and new weighting methodology to ensure comparisons are available over time where possible. Reports specifically relating to previous surveys will not be updated to include the backdated figures. This means figures will differ between those quoted in the 2017/18 reports and the relevant original survey reports.

Local level results for the survey have previously been published as a series of static reports but for the 2017/18 results they have been made available via an interactive dashboard. This allows users to look at the data that’s if interest to them and to make their own comparisons of the data. The interactive dashboard can be accessed at http://www.isdscotland.org/Products-and-Services/Consultancy/Surveys/Health-and-Care-Experience-2017-18/.
