At regular intervals during the year providers, such as NHS trusts, submit their data to the Secondary Uses Service (SUS). We then collect the data and add it to the HES data warehouse.
HES collects and holds data based on financial years. At the end of each year an Annual Refresh is processed (giving providers the opportunity to revise and update their submissions), and at this point we close the database and publish the final data.
This area gives details of the submission deadlines, the frequency of data collection and processing of HES.
