The following table contain the sum of the estimated alcohol attributable fractions (AAFs) for admission for patients via a general practitioner (GP) (Emergency) and hospital.
It should be noted that these figures are not a count of people and represent an estimated number of admissions that were attributable to alcohol.
AAFs are based on the proportion of a given diagnosis or injury that is estimated to be attributed to alcohol. Some diagnoses or injuries will, by definition, be wholly attributable to alcohol and have an AAF of one, others will only be partly attributable to alcohol and have an AAF greater than zero, but less than one. Diagnoses or injuries that are not attributable at all to alcohol will have an AAF of zero.
These figures are derived by summing all AAFs for the relevant admissions and should therefore only be interpreted as an estimate of the number of admissions that can be attributed to alcohol.
In addition, partial AAFs are not applicable to children aged under 16 years, therefore figures for this age group relate only to wholly – attributable admissions.

1. Alcohol–related admissions
The number of alcohol-related admissions is based on the methodology developed by the North West Public Health Observatory (NWPHO), which uses 48 indicators for alcohol-related illnesses, determining the proportion of a wide range of diseases and injuries that can be partly attributed to alcohol as well as those that are, by definition, wholly attributable to alcohol. Further information on these proportions can be found at http://www.nwph.net/nwpho/publications/AlcoholAttributableFractions.pdf
The AAF is set to 1 (100%) where the admission is considered to be entirely due to alcohol, e.g. in the case of alcoholic liver disease - these records are described as wholly alcohol attributable.
The alcohol attributable fraction is set to a value greater than 0 but less than 1 according to the NWPHO definition, e.g. the alcohol fraction of an admission with a primary diagnosis of C00 - malignant neoplasm of lip, where the patient is male and between 65 and 74 is 0.44 - these records are described as partly alcohol attributable.
These wholly and partly attributable fractions can be aggregated to supply an estimate of activity which can be considered wholly or partly attributable to alcohol.
Partly AAFs are not applicable to children under 16. Therefore figures for this age group relate only to wholly-attributable admissions, where the attributable fraction is one.
2. Finished admission episodes
A finished admission episode (FAE) is the first period of admitted patient care under one consultant within one healthcare provider. FAEs are counted against the year or month in which the admission episode finishes. Admissions do not represent the number of patients, as a person may have more than one admission within the period.
