Definitions of Keywords | Alcohol related conditions are defined by using the World Health Organization's International Classification of Diseases 10th Revision (ICD10). Alcohol related conditions used are: E24.4, E51.2, F10, G31.2, G62.1, G72.1, I42.6, K29.2, K70, K86.0, O35.4, P04.3, Q86.0, R78.0, T51.0, T51.1, T51.9, X45, X65, Y15, Y57.3, Y90, Y91, Z50.2, Z71.4, Z72.1. The lists of the ICD10 codes used in analysis of hospital data (general acute and psychiatric) codes have recently been revised. All historic data is based on the revised code list. The rate per 100,000 population is calculated using the European Age Standardised Rate (EASR) methodology. The age standardised rate is the number of events that would occur in a standard population (per 100,000) if that population had the age-specific rates for a given area. The rates are standardised to the European Standard Population. In December 2009 this indicator was revised and now records continuous inpatient stays. The overall effect on data trends is small but brings this indicator in line with the way ISD present data from the Scottish Morbidity Records 01 (SMR01) database: http://www.drugmisuse.isdscotland.org/publications/local/CIS_FAQ.pdf The revised indicator includes transfer cases but still excludes: - admissions to mental illness hospitals, psychiatric units and maternity hospitals.
- patients resident outwith Scotland or those where NHS board or council area of residence is not known.

Baseline and Past Trends | Alcohol related hospital admissions were steadily increasing over the decade that ended with the baseline year of 2006/07. The revised baseline figure for 2006/07 was 737 per 100,000, an increase of 38% from 1996/97 when the rate was 536 per 100,000. |
Methodology for Data Source | The indicator reports continuous inpatient stays, rather than the numbers of patients. The indicator reports general acute inpatient stays only. Psychiatric inpatient admissions with an alcohol-related diagnosis are not included due to concern over the consistency of this measure. The number of psychiatric hospital admissions may be falling due to more services being provided in the community, rather than a real fall in the number of alcohol-related psychiatric episodes. The recording of alcohol misuse may vary from hospital to hospital. Where alcohol misuse is suspected but unconfirmed it may not be recorded by hospitals. Changes in recording practices may impact on the number of alcohol-related admissions recorded. Alcohol-related admissions rates are subject to revision as there is no cut off for acceptance of SMR01 returns (although 99% are received within one year). |
Methodology for Recent Change Arrow on Scotland | This evaluation is based on: any difference within +/- 1.0% of last year's figure suggests that the position is more likely to be maintaining than showing any change. A decrease of 1.0% or more suggests the position is improving; whereas an increase of 1.0% or more suggests the position is worsening. |
