Healthcare providers collect administrative and clinical data locally to support the care of the patient. The data is submitted to the Secondary Uses Service (SUS).
At pre-arranged dates during the year, SUS consolidates those submissions and compiles the data as HES. It is then validated and cleansed, before deriving new items and making the information available in a database. Data quality reports and checks are completed at various stages in the cleansing and processing cycle.

The following interactive report provides a summary of high level counts of the extracts taken from SUS+. The first page gives a breakdown of number of records extracted by data set - Accident and Emergency (AE), Outpatient (OP) and Admitted Patient Care (APC) - and by organisation number and type (NHS and independent providers). The second page shows the number of records deleted from the SUS extract and the reason for the deletion. These removed records will not appear on the final HES data set. The third page offers some notes to clarify concepts or atypical trends.
