Clinical Trial Summary
Very little is known of depressed patients' mental state after being discharged from
inpatient wards where they are provided with a sheltered environment with stable sleep wake
cycle, regular meals, and regular physical and social activities. Our previous usability
study, SAFE I, showed that electronic self-monitoring was a useful tool to gain insight into
patients' condition in the weeks after discharge. Results showed that patients over a four
week period had significant day to day variations in self-rated mood and sleeping schedule
and that the patients' sleep patterns were delayed with 45 minutes.
In the actual study, SAFE II, we are investigating whether an intervention with a strong
focus on the circadian timing of daytime activities, and sleep, coined Circadian
Reinforcement Therapy (CRT), can lead to a faster recovery of depression and prevent relapse
into depression after discharge.
Description:
SAFE II Background Patients hospitalized with a depression are generally discharged within
4-6 weeks, but remain vulnerable, and not fully recovered at discharge, hence a majority will
be referred to outpatient care. Often, however, patients have to wait for about 2 weeks from
discharge to first visit in the outpatient clinic. Our clinical experience is that this
period from discharge to start of outpatient care is associated with psychological
uncertainty and often cause unstable daily routines for sleep, meals, social life, and
exercise. This may result in aggravation of the depression with the associated risk of
suicidal thoughts and readmission. Our first study "E-monitoring by depression - Safe I,"
illustrated these issues. Patients registered their state daily in an electronical
application, for sleep, mood, and exercise. Among other things the study showed that the
patients' sleep patterns were advanced to later in the evening and longer in the morning thus
shifting the sleep-wake cycle to later. One possible explanation for this finding is that
patients are not recovered from the depression when discharged and therefore are more
vulnerable to changes. Another possible factor is that at home the patients do not have the
same support to keep daily structure as during hospitalization. This project "Safe discharge
- SafeII" is based on the experience from the first study and will investigate whether a
focused intervention in the benefits of a stable sleep in the recovery of a depression can
help prevent worsening of the depression in the waiting time for outpatient treatment. It is
well documented that stable sleep and circadian rhythm is an important element in the
recovery of a depression.
Aim The purpose is to examine whether focused guidance to improve sleep habits and circadian
rhythms can speed up recovery and also prevent worsening of depression and thus prevent
readmission.
Design and Methods All patients hospitalized at PCK (Psychiatric Center Copenhagen) with a
unipolar depression, and referred to outpatient treatment at the Intensive outpatient unit
for affective disorders) (IAA) at discharge, are eligible for inclusion. Patient agreeing to
participate will be randomized to one of two groups. The standard care group consists of
patients who will be asked to register their mental state on a daily basis (mood, sleep and
exercise) in the electronical application Daybuilder (www.Daybuilder.com). This standard
group will have weekly telephone contact with the investigators. The intervention group will
also be asked to register their daily state in the Daybuilder app and have weekly telephone
contact with the investigators. In addition to standard care this group will also receive
individual guidance concerning the importance of stabilization of the sleep-wake cycle and
sleep to recover from depression. The primary outcomes of the study are changes in self-rated
mood and changes in Hamilton depression rating scores at baseline and endpoint in the two
groups and number of readmissions. We expect that the intervention group will have a more
rapid recovery of depression and have fewer readmissions. Furthermore, in a subset of
patients, the levels of the sleep hormone melatonin, a biological marker of circadian
rhythms, is measured, as a profile to establish the dim light melatonin onset (DLMO) at the
start and end of the intervention. At total of 150 patients, 75 in each group will be
included in the project over a three year period In this study we get the opportunity to see
the isolated impact of focusing on sleep and circadian rhythm in the recovery from
depression. We have coined this intervention Circadian Reinforcement Therapy (CRT).
Implications If the findings are positive, we expect to implement the intervention more
systematically in the psychiatric services thereby improving the conditions of patients with
depression by making the transition from in- to outpatient status less risky and more stable.
In the long term perspective the intervention can underpin recovery from depression, and
prevent relapse into depression and readmission in mental hospital.
