Hospital Episodes Statistics (HES) is a data warehouse containing records of all patients admitted to NHS hospitals in England. It contains details of inpatient care, outpatient appointments and A&E attendance records.
Hospital episode statistics (HES) statistics are produced and published on a monthly basis. This data is provisional and should therefore be treated as an estimate until the final National Statistics annual publications.
This publication series has recently been reviewed and now includes the most up to date provisional data within the headline figures presented. This change was first made in the ‘Month 10’ HES release in March 2016.
