Retrospective case note study
1 year of consecutive cases – 7 specialist
eating disorder services.
N=308 cases
Prescribing by primary care / CAMHS before
specialist service
Prescribing by specialist ED services
Gowers S.G. et al (2010) Drug prescribing in C&A eating disorder services. CAMH 15, 1, 18-22.
Results
308 cases (90% female)
Mean age 15 years, (range 8 -19 yrs).
An equal number of referrals came from primary care
and secondary CAMHS services.
Diagnosis
Anorexia nervosa (56%), Bulimia nervosa (7%) EDNOS
(37%).
71 (23%) had a co-morbid psychiatric problem
depression being the most prevalent (n = 23).
246 cases (80%) were offered treatment at the
specialist eating disorder services, 63 as in-patients
(26%).
Results (cont)
Drug Prescribing
Eighty three cases (26.9%) either at
assessment or later within an EDS, were
prescribed psychotropic medication.
Prescribing was uniform across all ages 1219 years.
There were no drug prescriptions below the
age of 12.

Beneficial and adverse effects
Fluoxetine
52 cases (17% of total series)
In 32 cases (62%) beneficial effects were reported.
In 10 cases (19%) adverse effects were reported
(increased self harm in 4).
Olanzapine
24 cases (8% of total series)
In 16 cases (67%) beneficial effects were reported.
In 9 cases (38%) adverse effects were reported predominantly drowsiness, hunger and constipation
Conclusions
A significant proportion (27%) of adolescents with
eating disorders are prescribed psychotropic
medication.
Surprisingly, 1/3 are prescribed psychotropic
medication prior to assessment at an eating disorder
service, but the majority (2/3 of prescriptions) are
made in specialist services.
The most used psychotropic drug is Fluoxetine followed
by Olanzapine.
Indications: mainly co-morbid psychiatric problems
such as depression.
Drugs appear to be tolerated quite well, even at low
weight . However, it is possible that both beneficial and
adverse effects may not have been recorded in some
cases.

What can we do about motives & to
improve motivation?
Can we enhance motivation?
Motivational Assessment:
Mean motivational score before i/v =
12.5
After assessment = 14.2
Giving patients power and choice in
negotiable areas
Identifying distant aims and agreeing
them
Using the patients’ strength of will
and using it to your advantage
