Please note: This is likely to be an under-estimation of the true number of alcohol-related hospital separations, as data for several alcohol-caused diseases (alcohol-induced pseudo-Cushing's syndrome; degeneration of nervous system due to alcohol; alcoholic polyneuropathy; maternal care for (suspected) damage to fetus from alcohol; fetus and newborn affected by maternal use of alcohol; fetal alcohol syndrome (dysmorphic); finding of alcohol in blood) are not publicly available for confidentiality reasons.

Alcohol-Caused Disease: A disease, disorder or condition which was directly caused by the individual’s own alcohol consumption.

Diseases classified as directly caused by alcohol use include: mental and behavioural disorders due to alcohol use; alcohol-induced pseudo-Cushing’s syndrome; degeneration of nervous system due to alcohol; alcoholic polyneuropathy; alcoholic myopathy; alcoholic cardiomyopathy; alcoholic gastritis; alcoholic liver disease; alcohol-induced acute pancreatitis; alcohol-induced chronic pancreatitis; maternal care for (suspected) damage to fetus from alcohol; fetus and newborn affected by maternal use of alcohol; fetal alcohol syndrome (dysmorphic); finding of alcohol in blood; toxic effect of alcohol; accidental poisoning by and exposure to alcohol; intentional self-poisoning by and exposure to alcohol; and poisoning by and exposure to alcohol, undetermined intent.

For confidentiality reasons, the 2022-23 National Hospital Morbidity Database excludes data for alcohol-induced pseudo-Cushing's syndrome; degeneration of nervous system due to alcohol; alcoholic polyneuropathy;; maternal care for (suspected) damage to fetus from alcohol; fetus and newborn affected by maternal use of alcohol; fetal alcohol syndrome (dysmorphic); finding of alcohol in blood; accidental poisoning by and exposure to alcohol; intentional self-poisoning by and exposure to alcohol; and poisoning by and exposure to alcohol, undetermined intent.

Hospital separation: An episode of care for an admitted patient, which can be:

• a total hospital stay (from admission to discharge, transfer or death); or
• a portion of a hospital stay beginning or ending in a change of type of care (for example, from acute to rehabilitation).

Separation also means the process by which an admitted patient completes an episode of care either by being discharged, transferring to another hospital, changing type of care, or dying.
