Summary Diagnoses ⏴ Hospital inpatientHealth-related outcomes


This category contains summary fields relating to diagnoses made during hospital inpatient admissions. The diagnosis data-fields list, for each participant, all the distinct values for that data-field in the inpatient data, including main and secondary diagnoses, coded according to the International Classification of Diseases (ICD-9 & ICD-10).

Most data-fields in this category have a corresponding field showing the date each diagnosis code was first recorded in the inpatient data. The date given is the episode start date (the EPISTART field on the HESIN table) or, if this was missing, the admission date (the ADMIDATE field on the HESIN table).

These fields are supplied as part of a main UK Biobank dataset.

See the Hospital Inpatient Data Dictionary (Resource 141140) for further information about these fields and the record-level tables from which they are derived.
