Clinical Trial Summary

According to the local guidelines (Recommendation for General Practitioners), the first choice Anti-Depressant (AD) in Major Depressive Disorder (MDD) in primary care should be selective serotonin reuptake inhibitors (SSRI), e.g. citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, in depression with anxiety and insomnia is preferable trazodone and in severer disorders mirtazapine. Despite all these molecules have a very good antidepressant effect, there are differences in side effect scale and tolerability.

The aim of this Study is describing of real treatment practice and MDD management in primary care - aimed to evaluate effectiveness of the treatments in depression and related symptoms: insomnia, anxiety, anhedonia and sexual dysfunction.

The primary objective of the Study is to describe the diagnostic process and treatment patterns in MDD- treatment of choice (pharmacologic with details of first choice antidepressant) in the office of GP's.

The secondary objective is to evaluate efficiency of the treatments in depression and related symptoms: insomnia, anxiety, anhedonia and sexual dysfunction and to monitor the type of side effects and comedication during the 8-weeks treatment.

Description:

Research question:

What are the common clinical practices adopted by general practitioner - diagnostic process and treatment of choice (pharmacologic with details of first choice antidepressant) in patients with newly diagnosed depression and how the diagnosis is performed.

Data sources:

Validated questionnaires (PHQ-9, GAD-7, SHAPS), quality of sleep measures with wrist actigraphy monitor. Questions dedicated to sexual dysfunctions. Data about patient's history, diagnosis, treatment and relevant side effects collected directly to the database.

Variables:

Primary Variables Sex and age of the patient. Type of treatment - one of the first line antidepressants available in GP's office (SSRIs, trazodone or mirtazapine) and specifications regarding the treatment approach: initiation dose of treatment, therapeutic dose of treatment, date of the dose increase, total day dose of treatment.

Secondary Variables Insomnia, anxiety and anhedonia will be evaluated by differences of scores of questionnaires (before and after treatment). Sexual dysfunction will be evaluated by differences of answers (before and after treatment).

• Proportional change in total sleep time (TST) before (1 day) /after (8 weeks) the initiation of treatment (TST is defined as the amount of actually sleep time in a sleep episode; this time is equal to the total sleep episode less the awake time).

• Sleep efficiency (time asleep / (total time in bed - time to fall asleep).

• Sleep latency (the duration of time from bedtime, to the onset of sleep).

• Sleep bouts (the number of occurrences of a bout (or multiple bouts), the average length of the bout(s), the total time spent in the bouts, and the total count level of the bouts).

• Sleep fragmentation index (index of restlessness during the sleep period expressed as a percentage).

Monitoring of the type of side effects and comedication during the 8-weeks.

Statistical methods:

Categorical parameters will be described by absolute and relative frequencies. Relative frequencies will be calculated based on the number of patients in relevant subgroup. Continuous parameters will be described by mean and standard deviation (SD) and median with minimum and maximum, together with the total number of non-missing observations.

The differences of the scores of the questionnaires (measured before and after treatment) will be also described by standard characteristics as mean (SD) and median (minimum-maximum). These differences will be tested by paired test (paired t-test or paired Wilcoxon test in dependence on meeting prerequisites). Differences with p-values < 0.05 will be statistically significant (analysis will be performed with level of significance α=0.05).

All statistical tests and confidence intervals will be of exploratory nature.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Description of the type of antidepressant	The variable type of antidepressant will be observed and evaluated.	patient duration: from enrollment to end of treatment for 8 weeks
Primary	Description of the dose of the antidepressant	The difference between the therapeutic and prescribed dose of antidepressant will be computed as therapeutic dose - prescribed dose.	patient duration: from enrollment to end of treatment for 8 weeks
Primary	Description of the increase of dose	The variable the increase of dose will be computed as changes of dose of comedication drug at the end of follow-up - dose of the drug at the start of follow-up.	patient duration: from enrollment to end of treatment for 8 weeks
Primary	Description of the time on an antidepressant without change of dose	Time on an antidepressant without change of dose will be computed as date of increase of dose - date of enrolment visit.	patient duration: from enrollment to end of treatment for 8 weeks
Primary	Description of the maximum daily dose of antidepressant	The variable maximum total daily dose will be observed and evaluated.	patient duration: from enrollment to end of treatment for 8 weeks
Secondary	Treatment efficiency - insomnia - change in total sleep time	Data about insomnia will be collected via a wireless-enabled wrist-worn actigraphy device.; Variable proportional change in total sleep time is defined as the amount of actual sleep time in a sleep episode; this time is equal to the total sleep episode less the awake time.	patient duration: from enrollment to end of treatment for 8 weeks
