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.
