1. Includes activity in English national health service hospitals and English NHS commissioned activity in the independent sector.
2. 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.
3. Alcohol-related admissions
The number of alcohol-related admissions is based on the methodology developed by the North West Public Health Observatory (NWPHO). Following international best practice, the NWPHO methodology includes a wide range of diseases and injuries in which alcohol plays a part and estimates the proportion of cases that are attributable to the consumption of alcohol. Details of the conditions and associated proportions can be found in the report Jones et al. (2008) Alcohol-attributable fractions for England: Alcohol-attributable mortality and hospital admissions.
4. Emergency admissions
Includes all types of emergency admission (Method of admission codes 21-28).
5. Finished admission episodes
A finished admission episode is the first period of in-patient 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 in-patients, as a person may have more than one admission within the year.
6. Primary diagnosis
The primary diagnosis is the first of up to 14 (seven prior to 2002-03) diagnosis fields in the Hospital Episode Statistics (HES) data set and provides the main reason why the patient was in hospital.
7. Secondary diagnoses
As well as the primary diagnosis, there are up to 13 (6 prior to 2002-03) secondary diagnosis fields in Hospital Episode Statistics (HES) that show other diagnoses relevant to the episode of care.
8. Number of episodes in which the patient had an alcohol-related primary or secondary diagnosis
These figures represent the number of episodes where an alcohol-related diagnosis was recorded in any of the 14 (seven prior to 2002-03) primary and secondary diagnosis fields in a HES record.
Each episode is only counted once in each count, even if an alcohol-related diagnosis is recorded in more than one diagnosis field of the record.
9. Data Quality
HES are compiled from data sent by more than 300 NHS trusts and primary care trusts in England. Data is 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.

|Departmental expenditure on allergy research (£000)|
The departmental figures relate to national research programme expenditure. They do not include the significant expenditure on allergy research from the research and development allocations that have over the last 10 years been made annually to national health service providers. That information is not held centrally.
The Medical Research Council (MRC) is one of the main agencies through which the Government support biomedical research. The MRC is an independent body funded by the Department for Innovation, Universities and Skills. It funds a large portfolio of allergy research.
Mr. Evennett: To ask the Secretary of State for Health what estimate he has made of the cost of prescribing anti-depressant drugs in the London Borough of Bexley in each of the last five years. 
Dawn Primarolo: The British National Formulary (BNF) classifies anti-depressant drugs within section 4.3. The following table shows the net ingredient cost for drugs within this section that have been prescribed in Bexley Care Trust, which covers the London borough of Bexley. As this information is available for the most recent 60 months at any one time, figures exist only for four complete financial years (April to March inclusive).
