1 A finished consultant episode (FCE) is a continuous period of admitted patient care under one consultant within one healthcare provider. FCEs are counted against the year in which they end. Figures do not represent the number of different patients, as a person may have more than one episode of care within the same stay in hospital or in different stays in the same year.

2 The primary diagnosis is the first of up to 20 (14 from 2002-03 to 2006-07 and seven prior to 2002-03) diagnosis fields in the HES data set and provides the main reason why the patient was admitted to hospital. The ICD-10 codes that have been used to define glaucoma are H40—Glaucoma and Q15.0 Congenital glaucoma.

3 Assessing growth through time. HES figures are available from 1989-90 onwards. Changes to the figures over time need to be interpreted in the context of improvements in data quality and coverage (particularly in earlier years), improvements in coverage of independent sector activity (particularly from 2006-07) and changes in NHS practice. For example, apparent reductions in activity may be due to a number of procedures which may now be undertaken in out-patient settings and so no longer include in admitted patient HES data.

Note:

HES are compiled from data sent by more than 300 NHS trusts and PCTs in England and from some 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. While this brings about improvement over time, some shortcomings remain.
