Trial summary

Mechanical ventilation (MV) is a vital support tool for critically ill patients. However, it may present several adverse effects, such as the development of cognitive and psychopathological alterations. Patient-ventilator asynchronies occur frequently since the beginning of the MV. Read more about this study

About this study

Official title: Influence of Persistent Patient / Ventilator Decoupling in Cognitive and Psychopathological Sequelae in Critically Ill Patients: A Multicenter Clinical and Mechanisticstudy

Mechanical ventilation (MV) is a vital support tool for critically ill patients. However, it may present several adverse effects, such as the development of cognitive and psychopathological alterations. Patient-ventilator asynchronies occur frequently since the beginning of the MV. These asynchronies are associated with poor clinical outcome and could be responsible for the neuronal changes causing these alterations. The objective of this project is to analyze the influence of patient-ventilation asynchronies in the development of long-term cognitive/psychopathological impairments and to explore the molecular mechanisms that could explain of these alterations. An exploratory, observational, multicenter, non-interventionist study will be performed in 150 ICU patients. The continuous recording of asynchronies and other clinical variables during ICU stay and the results of neuropsychological assessments will enable to identify clinical clusters associated with cognitive/psychopathological impairments.

Read the detailed description

MV parameters, as well as other physiological variables, will be monitorized during the ICU stay in all patients. A neurocognitive and psychopathological assessment will be administed in all patients at 1-month and 1-year follow up.

After data collection, an asynchronies index will be calculated. A clusters analysis, based on clinical variables and asynchronies index, will be performed. The relationship between patients' clusters and the neuropsychological/ psychopathological data will be analized.

CLINICAL STUDY Univariate descriptive analysis: for quantitative variables the mean, standard deviation, percentiles 25, 50 and 75, minimum is calculated and maximum. For qualitative variables, the absolute and relative frequencies were calculated. Population interval will be estimated at 95% confidence level.

Multivariate analysis: cluster analysis, with the intention to investigate possible associations of individuals and characterization of the profile of each cluster. Comparison of standardized scores (z) of the neuropsychological variables and asynchronies index between clusters will be carried out by parametric or nonparametric techniques, as more appropriate.

Association of asynchrony with the neuropsychological variables: conditional logistic regression (case-control) of the scores of neuropsychological variables (dichotomized) versus asynchronies index will be performed, controlling for confounding covariates or factors that may have a modifier effect. The multivariate case-control matching will be performed by the method of propensity score or by genetic algorithms. The odds ratio and confidence interval of 95% was estimated.

Sample size: has been used rule of thumb for logistic regression models include between 10-15 cases per covariate. In this case, the sample will consist of 150 patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Critical Illness, run by Corporacion Parc Tauli at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Short-term neurocognitive alterations (time frame: 1month after ICU discharge). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02390024, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2020.
