PMID 34972842WHAT IT FOUND
ICU ABCDEF bundle use rose slowly with a national collaborative, reaching 12% complete bundle performance after 14 months.
Early mobility remained under 40% in most units, and no patient outcomes were measured.
Key findings
01Complete bundle performance increased by 0.6 percentage points each month during implementation and reached 12% by the final month.
02Early mobility was performed at less than 40% in most ICUs by the end of the collaborative.
03Pain assessment, sedation assessment, and family engagement rose immediately after the collaborative began, and more than half of ICUs reached at least 70% performance for them by the end.

What it does not show
The study measured ICU process performance, not patient recovery, so it cannot show that the bundle made patients better. This was an observational interrupted time series study, so other changes over time could explain some improvement. The immediate increase in complete bundle performance was not statistically significant. Each ICU used its own safety screen rules for SAT, SBT, and mobility, so low performance may partly mean patients were too unstable for those steps rather than that clinicians skipped them. Sites volunteered for the collaborative, so results may be better than in ICUs that did not take part. The study lasted 20 months and cannot show whether gains lasted. Variation among ICUs was large and unexplained.

The easy way to misread this
Do not read this as proof that the ABCDEF bundle improved patient outcomes. The study measured documented bundle delivery, and complete delivery reached only 12% after 14 months, so it shows a slow implementation trend, not proven patient benefit.
