Finished admission episodes A finished admission episode is the first period of inpatient care under one consultant within one healthcare provider. Finished admission episodes are counted against the year in which the admission episode finishes. Admissions do not represent the number of inpatients, as a person may have more than one admission within the year. Primary diagnosis The primary diagnosis is the first of up to 20 (14 from 2002-03 to 2006-07 and 7 prior to 2002-03) diagnosis fields in the Hospital Episode Statistics (HES) data set and provides the main reason why the patient was admitted to hospital. Data quality HES are compiled from data sent by more than 300 NHS trusts and primary care trusts (PCTs) in England. Data are also received from a number of independent sector organisations for activity commissioned by the English NHS. The NHS 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. While this brings about improvement over time, some shortcomings remain. PCT/strategic health authority (SHA) data quality PCT and SHA data were added to historic data years in the HES database using 2002-03 boundaries, as a one-off exercise in 2004. The quality of the data on PCT of treatment and SHA of treatment is poor in 1996-97,1997-98 and 1998-99, with over a third of all finished episodes having missing values in these years. Data quality of PCT of GP practice and SHA of General practitioners practice in 1997-98 and 1998-99 is also poor, with a high proportion missing values where practices changed or ceased to exist. There is less change in completeness of the residence-based fields over time, where the majority of unknown values are due to missing postcodes on birth episodes. Users of time series analysis including these years need to be aware of these issues in their interpretation of the data. Assessing growth through time HES figures are available from 1989-90 onwards. The quality and coverage of the data have improved over time. These improvements in information submitted by the NHS have been particularly marked in the earlier years and need to be borne in mind when analysing time series. Some of the increase in figures for later years (particularly 2006-07 onwards) may be due to the improvement in the coverage of independent sector activity. Changes in national health service practice also need to be borne in mind when analysing time series. For example, a number of procedures may now be undertaken in out-patient settings and may no longer be accounted for in the HES data. This may account for any reductions in activity over time. Small numbers To protect patient confidentiality, figures between one and five have been suppressed and replaced with "*" (an asterisk). Where it was possible to identify numbers from the total due to a single suppressed number in a row or column, an additional number (the next smallest) has been suppressed.
