Objectives:
To determine the effects of a brief
psychological intervention (brief psychodynamic interpersonal therapy)
for patients after deliberate self poisoning compared with usual
treatment. To compare the impact of the active intervention and usual
treatment on patients' satisfaction with care.
What is already known on this topic
What this study adds
Design:
Randomised controlled trial.
Participants:
119 adults who had deliberately poisoned
themselves and presented to the emergency department of a teaching hospital.
Setting:
Community based study.
Intervention:
Four sessions of therapy delivered in
the patient's home. Control patients received "treatment as
usual," which in most cases consisted of referral back to their
general practitioner.
Outcome measures:
Severity of suicidal ideation six
months after treatment as assessed by the Beck scale for suicidal
ideation. Secondary outcome measures at six month follow up included
depressive symptoms as measured by the Beck depression inventory,
patient satisfaction with treatment, and self reported subsequent
attempts at self harm.
Results:
Participants randomised to the intervention had a significantly greater reduction in suicidal ideation at six month
follow up compared with those in the control group (reduction in the
mean (SD) Beck scale 8.0 v 1.5). They were more satisfied with their treatment and were less likely to report repeated attempts to harm themselves at follow up (proportion repeating 9% v
28% in control group; difference 19%, 95% confidence interval 9% to 30 %, P=0.009).
Conclusion:
Brief psychodynamic interpersonal therapy may be a valuable treatment after people have deliberately tried to
poison themselves.
Deliberate self poisoning is one of the commonest reasons for admission
to hospital in the United Kingdom and up to 15% of patients who poison
themselves eventually kill themselves
Compared with usual treatment four sessions of psychodynamic
interpersonal therapy reduced suicidal ideation and self reported
attempts at self harm
