Your health records

With your permission the Yorkshire Health Study would like to follow your health by linking with your health records. Just like when you are asked if you would be happy to be contacted again, at the end of the health questionnaire we ask whether you would allow us to link the information you have provided to your health records.


More specifically we wish to link the information you have provided in your questionnaire with Hospital Episode Statistics (HES). HES has details of all NHS admitted patient care, outpatient appointments and A&E attendances in England. It includes private patients treated in NHS hospitals, patients resident outside of England and care delivered by treatment centres (including those in the independent sector) funded by the NHS.


Each HES record contains a wide range of information about an individual patient admitted to an NHS hospital, including:

  • clinical information about diagnoses and operations

  • information about the patient, such as age group, gender and ethnicity

  • administrative information, such as time waited, and dates and methods of admission and discharge

  • geographical information such as where patients are treated and the area where they live


It contains admitted patient care data from 1989 onwards, outpatient attendance data from 2003 onwards and A&E data from 2007 onwards.


Why do you want this information?

By linking information you have provided in your questionnaire to HES data, we are able to get more of an accurate picture of your health and healthcare. This is important in order to provide researchers with the most accurate and up to date information. Again this will be anonymised and you will not be identified.



The Yorkshire Health Study will:

  • Make sure that your records remain confidential and advise our researchers on how these records should be handled in accordance with the Data Protection Act 1998 in order to comply with your rights.

  • Work together with the official organisations which collect your records to protect your privacy.

  • YHS will respect your consent decision.
