How long Emergence Delirium studies take

Of 50 phase 4 interventional studies under Emergence Delirium, half reached primary completion within 19 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 419 mo11–33 · 50 studies—19 mo11–33 · 50 studies
Interventional, no phase19 mo7–36 · 186 studies—19 mo7–36 · 186 studies
Observational21 mo10–43 · 180 studies—21 mo10–43 · 180 studies

Each figure is the month by which half the studies had reached primary completion, with the range in which the middle half did. Studies still running count until their last registry update; studies that stopped early are left out. Phase 1 includes early phase 1; observational means prospective or not stated, as retrospective and cross-sectional studies date a window of data rather than a study.
