Continuity of data
All data are revised annually to reflect any changes to analysis and to ensure the most complete information is presented. Data for the most recent financial year are labelled as provisional and may be subject to change in forthcoming publications. Minor revisions of this nature are often due to incomplete data returns at the time of the previous publication.
Revisions relevant to this publication
In previous publications, the ‘multiple/other’ drug category comprised the following ICD-10 codes:
Mental and behavioural disorders due to: Hallucinogens
Mental and behavioural disorders due to: Volatile Solvents
Mental and behavioural disorders due to: Multiple/Other Drugs
Poisoning by narcotics: Unspecified Narcotics
Poisoning by narcotics: LSD
Poisoning by narcotics: Unspecified Hallucinogens
Toxic effect of organic solvents
*Provided at least one of the ICD-10 mental and behavioural codes were present (F11-F16, F18, or F19).
In this publication, the codes F16, T40.8 and T40.9 were brought together to form a new 'hallucinogen' drug type category, while the remainder of the codes listed above were retained in the 'multiple/other' category.
This has had the effect of slightly reducing the number of drug-related hospital stays that were attributed to 'multiple/other' drugs. In 2019/20, there were 3,432 stays with 'multiple/other' drug category recoded, and 183 stays where hallucinogens were recorded. If the original coding had been used there would have been 3,597 stays in the ‘multiple/other’ category. Please note that there may be more than one drug-related diagnostic code recorded on a stay, so the sum of stays associated with individual drug categories will not be equal to the overall total of drug-related stays.
