Note on English inpatient data
UK Biobank has started to receive monthly extracts of hospital inpatient data for England from NHS Digital, with each file containing the whole financial year to that point. Whilst we remove exact duplicates of previous episodes, we have noted occasions where a second record exists which differs slightly from a previous episode despite clearly being a record of the same hospital episode. Currently, both versions of this same episode will appear in our released data.
We are exploring methods for retaining only the most recent version of each episode, and hope to be able to do this in the next few months. For now, researchers should take this issue into consideration when working with the English inpatient data.
Updates to the Data Portal
The table below gives details of the current status of the tables on the Data Portal, in particular when they were each last updated. The frequency with which new data will be made available will vary by table and could change over time.
The data on this table is refreshed each night so updates will appear the day after new data have been added to the tables. The row counts will sometimes decrease due
to data being removed for participants who have withdrawn from the study.
