Key findings

What ClinicalTrials.gov does not surface for Delirium on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Delirium recruits in line with its size-band peers.

    24 of 63 indexed trials (38.1%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Delirium trials is spread across many organizations.

    Vanderbilt University Medical Center accounts for 5 of 63 trials (7.9%). 39 distinct sponsors appear on at least one study for this condition label.

  3. Typical Delirium enrolment sits around 135 participants.

    Median target enrolment is 135 among the 63 trials that report a genuine target (sentinel values excluded). 21 of those (33.3%) plan for fewer than 100 participants.

  4. Delirium splits between interventional and observational designs.

    44 interventional and 19 observational studies make up this index (69.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
