C2 Psychiatric discharges
Key points 2005/06
Overview
- In 2005/06 there were 24,632 psychiatric discharges in
Scotland, of which 1,623 had a diagnosis of drug misuse (a rate of
33 discharges per 100,000 population) (Tables C2.2 and C2.3).
- During 2005/06 the ratio of discharges to patients was 1.3
(Table C2.1).
- Of the 1,623 psychiatric discharges relating to drug misuse
over 70% (1,162) were re-admissions (Table C2.2).
- Over two-thirds (1,119) of drug misuse discharges were males
compared with 504 discharges for females (Table C2.2).
- The majority of patients who were discharged with a diagnosis
of drug misuse were aged under 40 years old (81%). The 25 to 29
years old age group had the highest rate of discharges, with 115
per 100, 000 population (Table C2.2).
- Where a main diagnosis of drug misuse was recorded with
supplementary diagnoses, the most common specific supplementary
diagnoses were mood (affective) disorders (42) and mental and
behavioural disorders due to drug use (55) (Table C2.4).
- More than two-fifths (737) of discharges involved a
supplementary diagnosis for drug misuse. In these cases the most
common main diagnoses were schizophrenia (238) and mood affective
disorders (145) (Table C2.5).
Five year trends – 2001/02 to 2005/06
- There has been little change in
the rate of psychiatric discharges with either a main or
supplementary diagnosis of drug misuse between 2001/02 and 2005/06
(fluctuating between a maximum of 38 per 100,000 population and a
minimum of 33 per 100,000 population) (Table C2.2).
- Similarly, there was little variation over the 5 year period in
the rate per 100,000 population of psychiatric discharges where
drug misuse was recorded as the main diagnosis only. The rate lay
between a maximum of 24 discharges per 100,000 (in 2002/03) and a
minimum of 19 per 100,000 (in 2005/06) (Table C2.2).
- Some of the younger age groups (15 to 29 years old) showed a
slight downward trend in the rate of discharges with a diagnosis of
drug misuse per 100,000 population between 2001/02 and 2005/06.
Some older age groups (40 to 49 years old) showed a slight upward
trend over the same period. (Table
C2.2).
Drugs recorded
- The most common specifically
recorded drug was opioids with 26% of cases (424). Cannabinoids was
the second most commonly recorded drug with 12% of discharges (201)
(Table C2.6).
Geographical
Profile
- The highest rate of discharges
per 100,000 population was seen in NHS Dumfries and Galloway, with
73 per 100,000 population. The second highest rate was NHS Ayrshire
and Arran with 68 per 100,000 (Table C2.2).
Background
information
Data on individual patients are collected by ISD Scotland as a
series of Scottish Morbidity Records (SMR).
The SMR datasets are a significant local and national
information resource, and are used for epidemiological monitoring,
health needs assessment, national and local planning and a range of
other applications.
These statistics are derived from data collected through the
mental health inpatient and day case return (SMR04), which records
information at admission and discharge. On the SMR04 form up to six
separate diagnoses can be recorded on discharge. A diagnosis in the
first position is the main diagnosis on discharge. A diagnosis `in
any position', refers to the occurrence of a diagnosis in any of
the six positions (including main and supplementary).
Figures for all admissions, re-admissions and discharges relate
to the number of episodes not to the number of individual patients
admitted or discharged. Each individual may have more than one
episode. First admissions relate to first ever admissions to a
psychiatric hospital, and therefore approximate to the number of
people. It is also important to note that re-admissions will
include patients who have returned for treatment after a long
period of time, as well as those who have been re-admitted after a
short interval.
When figures are broken down by geographical area or age the
numbers in some categories can be very small. In these cases both
differences between categories and trends over time should be
interpreted with caution because they may be misleading.
Diagnosis is recorded on both the admission and the discharge
part of the record and diagnosis on discharge may differ from
diagnosis on admission. The tables presented here are based on
diagnosis on discharge. Drugs misuse is defined using the same
group of ICD 10 codes outlined in section C1. In tables C2.3 to
C2.5 diagnoses have been grouped together into the following short
list of conditions based on the International Classification of
Diseases 10th Revision (ICD10):
