|Number of FCEs in each speciality and in total at West Hertfordshire NHS Acute Trust 2000-07|

* To protect patient confidentiality, figures between one and five have been suppressed and replaced with an asterisk.
(1) In October 2006, the management of the speciality Plastic Surgery transferred from the West Hertfordshire NHS Acute Trust to the Royal Free Hampstead NHS Trust. This is a likely explanation for the drop in count of FCEs in 2006-07 compared to the data received in previous years.
(2) For 2001-02 no data were received from the trust for the speciality Paediatrics. This has been investigated with the trust but no conclusive cause has been found.
1. Data Quality
HES are compiled from data sent by over 300 national health service 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. While this brings about improvement over time, some shortcomings remain.
2. Assessing growth through time
HES figures are available from 1989-90 onwards. During the years that these records have been collected the NHS there have been ongoing improvements in quality and coverage. 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. Changes in NHS 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 in the HES data. This may account for any reductions in activity over time.
A FCE is defined as a period of admitted patient care under one consultant within one healthcare provider. The figures do not represent the number of patients, as a person may have more than one episode of care within the year.
Care is needed when analysing HES data by specialty, or by groups of specialties (such as acute). Trusts have different ways of managing specialties and attributing codes so it is better to analyse by specific diagnoses, operations or other recorded information. Trusts may change the way they manage speciality codes through time. The number of specialities can change over time depending on the patients being treated and the consultants employed by a trust in a particular year.
5. Ungrossed data
Figures have not been adjusted for shortfalls in data (ies the data are ungrossed).
