Notes
This field indicates (for each participant) the number of in-patient Health Episode Statistics (HES) records in the UKB repository which contain "Date of operation" information. Participants with zero records are not itemised.
This date corresponds to the main operation only. (For secondary operations and procedures, see Field 41082 - Episodes containing "Dates of operations" data.)
In order to conduct analyses using this information, researchers must include this data-field in their application, however access will be given in-situ rather than as a download.
