Alcohol dependence (Indicator 5)
This indicator is part of Target (2): At least a 10 per cent reduction in harmful alcohol consumption.
To determine the proportion of individuals with alcohol dependency, interviews must be conducted among the general population. Such a population study is being planned as part of the Health Survey in Nord Trøndelag (HUNT)
The Cause of Death Registry provides data on the number of alcohol-related deaths.
The national health registries for the primary and specialist health services describe the proportion of individuals with alcohol-related illnesses who have been detected by the health service, and therefore provide data on the frequency of contact with the health service regarding alcohol-related illnesses.
The annual number of alcohol-related deaths has remained stable during the period 2005-2017. Less than half of these deaths were due to chronic alcohol dependence (Figure 1).
In comparison, approximately 6 out of 1000 of the population were in contact with primary or specialist health services due to chronic alcohol dependence or harmful use of alcohol in 2014. This is shown by data collected from the Norwegian Patient Registry and from the Norway Control and Payment of Health Reimbursements (KUHR) Database for 2014.
The data sources for this indicator are the Cause of Death Registry, the Norwegian Patient Registry and the Norway Control and Payment of Health Reimbursements (KUHR) Database.
Results from other data sources will be published at a later date: A diagnosis-based population survey of mental health conditions and drug and alcohol-related illnesses is a part of the HUNT4 study.
Descriptions and definitions of the Cause of Death Registry, the Norwegian Patient Registry and the Norway Control and Payment of Health Reimbursements (KUHR) Database follow below.
Data source: Cause of Death Registry
The cause of death statistics are compiled on the basis of death certificates completed by public sector doctors. In addition, information is obtained from the Norwegian Cancer Registry, the Medical Birth Registry of Norway, hospital autopsy results and forensic examinations.
The following ICD10 diagnosis codes are included for alcohol-related deaths:
- Mental and behavioural disorders due to use of alcohol (F10), in which the diagnosis F10.2 alcohol dependence, was an important underlying cause of death in this group.
- Damage to the nervous system due to alcohol (G32.1, G62.1, G72.1)
- Alcoholic liver disease (K70)
- Alcoholic cardiomyopathy (I42.6)
- Poisoning accidents with exposure to alcohol (X45, Y15)
- Other deaths that are due to alcohol abuse:
- Alcoholic gastritis (K29.2)
- Alcohol-induced pancreatitis (K85.2, K86.0)
- Fetal alcohol syndrome (Q86.0)
- Other alcohol-induced damage (E24.4, P04.3)
- Intentional self-poisoning by and exposure to alcohol (X65)
- Number of alcohol-related deaths per 100 000 persons per year in a five-year moving average, in the population 15 years and older.
- Standardised values are recommended when looking at trends over time. The purpose of standardisation is to reduce the effect of different age compositions when comparing groups in time and space. The method employed is direct standardisation with a fixed standard population taken as the reference population. The European standard population in 2013 is used as the standard population (ESP 2013, Eurostat)
Interpretation and sources of error
Alcohol-related mortality includes three main groups: Death due to chronic alcohol dependence, death due to alcohol poisoning and death due to disease in internal organs as a result of alcohol abuse. Where there are no specific diagnoses connected to cases of alcohol abuse, “chronic alcohol dependence” is often used as an underlying cause of death.
The data quality is deemed to be generally good. However, the number of autopsies being performed is declining steadily, making quality assurance of diagnoses difficult.
Data source: Norwegian Patient Registry
The Norwegian Patient Registry contains health data on patients who have received or are waiting for treatment via the specialist health service.
Here, data on alcohol dependence from 2014 is provided as an example of the use of data from the Norwegian Patient Registry.
The number of patients per 1000 population who have been in contact with the specialist health service in the course of 2014 where the following ICD-10 diagnoses were given:
- F10.1: Harmful use of alcohol
- F10.2 : Chronic alcohol dependence
Data source: Norway Control and Payment of Health Reimbursements (KUHR) Database
The settlement system for the Norway Control and Payment of Health Reimbursements (KUHR) Database has been established to manage financial arrangements for GPs and other health personnel performing services that are reimbursed under the National Insurance scheme. Diagnoses are given at the level of the individual for every patient encounter.
Data from 2014 on chronic alcohol dependence are provided here as an example of the use of data from KUHR.
The number of patients per 1,000 population who have been in contact with the primary health service during the course of 2014 where the following ICD-II diagnoses were given:
- P15: Chronic alcoholism
|Chronic alcohol dependence||Alcoholic liver disease and alcoholic cardiomyopathy||Accidents with alcohol poisoning||Other deaths due to alcohol abuse||Total deaths due to alcohol use|
National adaptation to global indicators
WHO’s definition of the indicator
Indicator 5. Alcohol-related morbidity and mortality among adolescents and adults, as appropriate, within the national context.
WHO has defined alcohol-related morbidity and mortality based on the diagnosis codes F10.1 Alcohol abuse and F10.2 Alcohol dependence, both of which are in the group “F10 Alcohol related disorders”.
In Norway, “chronic alcohol dependence” is often stated as an underlying cause of death in the absence of more specific diagnoses connected to a case of alcohol abuse. Thus, in the Norwegian national context, inclusion of deaths due to alcohol poisoning and deaths due to disease in internal organs as a result of alcohol abuse is relevant when the aim is to show data on mortality related to alcohol consumption.
