Multicomponent nonpharmacological care,
does it really help with Reduction of incident delirium among adults hospitalized outside intensive care?
research showsThe grade is C. A 2021 Cochrane review pooled 14 multicomponent randomized trials with 3,693 participants and found RR 0.57 (95% CI 0.46 to 0.71; I-squared 39%). The 10.5% versus 18.4% figures are calculated absolute risks from the summary-of-findings baseline risk and relative effect, not simple totals of raw events. Outcome-assessor risk was high in six trials, unclear in one, and low in seven; the unadjusted cluster design in Hosie added a separate flaw, giving C with 54 points.
ads claimThis was a comparison of a structured bundle with usual care. The 43% relative reduction cannot be attributed separately to sleep, drinking, walking, glasses, or cognitive activity.
Useful facts when choosing a product
- Bundles varied but commonly addressed orientation, cognition, sleep, mobility, sensory support, nutrition, and hydration.
- Controls received usual hospital care rather than no care.
- Validated delirium methods included CAM, DRS-R-98, and DSM criteria.
What the research actually shows
The Cochrane review included 22 non-ICU randomized trials with 5,718 participants; 14 trials with 3,693 participants contributed to the multicomponent-versus-usual-care delirium analysis. Across trials, bundles combined reorientation and familiar objects, cognitive stimulation, sleep hygiene, early mobility, glasses or hearing aids, nutrition and hydration, oxygenation, infection identification, pain control, medication review, bowel and bladder care, and mood assessment. Controls received usual hospital care. Delirium was repeatedly assessed during admission with validated methods including CAM, DRS-R-98, DSM-IV, or DSM-5. Marcantonio used daily blinded interviews and CAM and found 20/62 (32%) versus 32/64 (50%). Among the 14 multicomponent trials, outcome-assessor risk was high in six, unclear in one, and low in seven. The Cochrane assessment identified no cluster adjustment in Hosie 2020; its original methods section was not directly checked here. Excluding cluster trials gave RR 0.65 (95% CI 0.55 to 0.77).
Why this is classified as C (54)
Delirium reduction was present, but only one individual trial was cited and two distinct avoidable flaws were identified, giving C with 54 points.
Counterpoint. Verdict 1148 is F with 18 points for melatonin alone. Verdict 2302 asks a different question about a multicomponent care bundle versus usual care.
Rejudgment record. Cross-check applied — Delirium reduction with limited individual-trial citation, avoidable unblinded assessment, and unadjusted clustering in Hosie
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduction of incident delirium by the multicomponent bundle | C | Summary-of-findings calculated risks were 10.5% versus 18.4%. |
| Isolated effect of sleep or mobility alone | ? | Bundle comparisons cannot establish the isolated effect of each component. |

Evidence Table
| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Study 1 | Systematic review of randomized non-ICU trials | 3,693 | Review supported by NIHR and Medical Research Scotland; multiple included trials had public or nonprofit funding | Incident delirium during admission using validated instruments | Summary-of-findings calculated risks 10.5% versus 18.4%; RR 0.57 (95% CI 0.46 to 0.71), I-squared 39% | Pivotal pooled evidence |
| Study 2 | Individually randomized hip-fracture trial with blinded outcome assessment | 64 | Public funding from the US National Institute on Aging | Incident delirium by daily interviews and CAM | 20/62 (32%) versus 32/64 (50%); RR 0.64 (95% CI 0.37 to 0.98) | Only individually cited primary trial |
