Notes:
1. Information is based on date of discharge (rather than date of admission)
2. Excludes misuse of tobacco or alcohol.
3. Includes type of admission not known, and cases with a missing or invalid response.
4. Includes transfers from other psychiatric inpatient care.
5. Diseases recorded using the World Health Organization's International Classification of Diseases 10th Revision (ICD10). ). Drug-related codes: F11, F12, F13, F14, F15, F16, F18, F19. Up to six diagnoses are recorded. All six diagnoses have been used to identify drug related conditions.
6. Caution is necessary when interpreting these figures. The recording of drug misuse may vary from hospital to hospital. Where drug misuse is suspected but unconfirmed it may not be recorded by the hospital.
7. Information on psychiatric discharges for drug misuse in 2010-11 is not currently available for public release. Figures for this period will be published by NHS Information Services Division (ISD) Scotland in 2013.
8. Patients resident outside Scotland or whose NHS board or council area of residence is not known are included in this analysis. Therefore these figures will be between 3-5% greater than previously published figures.

Notes:
1. Excludes mental illness hospitals, psychiatric units and maternity hospitals.
2. Information is based on date of discharge (rather than date of admission) because the SMR01 dataset is a discharge summary record.
3. Figures in Table 2 relate only to those individuals who are treated as inpatients or day cases in an acute hospital. They do not include individuals managed as outpatients.
4. Diseases recorded using the World Health Organisation’s International Classification of Diseases 10th Revision (ICD10). Drug-related codes: F11, F12, F13, F14, F15, F16, F18, F19. Up to six diagnoses are recorded. All six diagnoses have been used to identify drug related conditions.
5. Caution is necessary when interpreting these figures. The recording of drug misuse may vary from hospital to hospital. Where drug misuse is suspected, but unconfirmed it may not be recorded by the hospital.
6. Patients resident outside Scotland or whose NHS board or council area of residence is not known are included in this analysis. Therefore, these figures will be between 1-2% higher than previously published figures by ISD.
