This may be due to poor recording of the admission date and/or decision to admit date. Note: FAE A FAE is the first period of in-patient care under one consultant within one healthcare provider. Admissions do not represent the number of in-patients, as a person may have more than one admission within the year. Data Quality Hospital Episode Statistics (HES) are compiled from data sent by over 300 NHS Trusts and Primary Care Trusts (PCTs) in England. The Information Centre for health and social care liaises closely with these organisations to encourage submission of complete and valid data and seeks to minimise inaccuracies and the effect of missing and invalid data via HES processes. Whilst this brings about improvement over time, some shortcomings remain. Main Operation The main operation is the first recorded operation in the HES data set and is usually the most resource intensive procedure performed during the episode. It is appropriate to use main operation when looking at admission details, e.g. time waited, but the figures for 'all operations' count of episodes give a more complete count of episodes with an operation. OPCS 4.2 codes used: W37,W38,W39,W46,W47,W48Time Waited (days) Time waited statistics from HES are not the same as the published waiting list statistics. HES provides counts and time waited for all patients admitted to hospital within a given period whereas the published waiting list statistics count those waiting for treatment on a specific date and how long they have been on the waiting list. Also, HES calculates the time waited as the difference between the admission and decision to admit dates. Unlike published waiting list statistics, this is not adjusted for self-deferrals or periods of medical/social suspension. Source: (HES), The Information Centre for health and social care.
