Why
  1. Critical Illness is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Unconsciousness.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This study aims to gather insights into the perceptions of legal representatives regarding the recruitment process for clinical trials in the intensive care setting when the patients cannot decide for themselves. With this information, effective strategies will be developed to increase involvement and the feeling of ownership of LARs of (potential) participants in clinical trials and thus enhance and facilitate patient recruitment for clinical trials. The single-arm study design does not include a choice of comparator, as the focus of this trial is to explore the perceptions of the participants at first hand without comparing different cohorts or strategies.

Read the detailed description

The evidence for specific therapies and treatment strategies, particularly for critically ill patients, remains limited. A significant difficulty for the planning, initiation and implementation of clinical trials in these patients is the urgency of the necessary medical measures, which leaves patients and their relatives, as well as the treating clinicians, little time and opportunities to present necessary studies and to inform the patients or their legal guardians about them. Critically ill patients are a particularly vulnerable group of patients. The measures required as part of a study can mean additional efforts for these patients over and above the burden of the disease and the necessary diagnostic and therapeutic measures, which are only justified if special duties of care are observed. In addition to an ethical assessment of the study, this also includes providing comprehensive information to patients or their legal representatives.

In this study, the process of informing and educating patients or their legal representatives will be examined in more detail. The aim of the study is to gain a better understanding of this process, in particular the perceptions and views of the persons to be informed, and specifically to investigate which aspects are particularly important to patients and their legal representatives in an information and education discussion and what information they need in order to be able to consider participating in a study or what reasons exist that would prevent them from giving their consent. The overall aim of this study is to improve the information and education process.

For some years now, the involvement of patients and relatives in individual aspects of the planning and conduct of clinical trials has been increasingly demanded and promoted. For example, large public funders often require the involvement of patient and/or family representatives at an early stage in the planning of trials. The objectives of this study are based on these expectations.

What researchers measure

Primary outcomes

  1. relative/LAR perception

    The primary aim of the study is to evaluate the perceptions of LARs towards the recruitment process for clinical trials. This is an exploratory examination. All findings are considered merely hypothesis generating and will be used for designing further trials based on sound hypotheses following the findings from this trial.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2024 (actual). Primary completion is estimated for Jun 2026, 23 months after the start.

Of 16 interventional studies with no phase under Unconsciousness, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 40. This study's planned 23 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 24, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
