Sedation Influence on Delirium & Post-traumatic Stress-disorder as a

Status Completed

Clinical Trial Summary

The aim of this study is to investigate if sedation of Intensive Care Unit (ICU) patients influences the development of delirium during their ICU stay and if incidences of delirium have an impact on the development of Post-traumatic Stress-Disorder (PTSD).

Hypothesis 1:

Patients who are minimally sedated, remember staying in ICU and experiences fewer episodes of delirium than patients that are heavily sedated

Hypothesis 2:

Former delirious patients are more likely to develop PTSD

Hypothesis 3:

Delirium decreases health-related quality (HRQoL) of life after discharge

Clinical Trial Description

Background:

It is known that ICU patients that experience delirium have longer hospital stay, higher mortality and morbidity. Other studies indicate that PTSD, dementia or depression may emerge after discharge from hospital.

Methods according to hypothesis 1:

During ICU stay: Measure sedation level & delirium. First follow-up 1-2 weeks after ICU: Memories

Analyses:

Data will be analyzed descriptive via EPIDATA and Stata Delirium is endpoint, defined as CAM-ICU positive. Sedation level is exposure variable.

Confounders: priory antipsychotic treatment or hypertension,glasses or hearing aids,alcohol and tobacco abuse,degree of illness,age and sex.

Correlation between sedation level and memories will be calculated.

Methods according to hypothesis 2:

Screening for: PTSD, Depression, Anxiety

Analyses:

PTSD is endpoint, and delirium is the exposure variable. Main confounders: Anxiety and Depression Mean of PTSD will be calculated with Confidence Interval to test any difference between experienced delirium or not.

Methods according to hypothesis 3:

Method:Health-related quality of life is endpoint, Activities of daily living (ADL), Memories, and a Script Test (only after 2 month)

Analyses:

Mean of HRQoL will be calculated with Confidence Interval to test any difference between experienced delirium or not.

Confounders: Diary and/or Follow up ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
