The association between delirium and falls in older adults in the community: a systematic review and meta-analysis
Bibliographic record
Abstract
OBJECTIVE: Systematically review and critically appraise the evidence for the association between delirium and falls in community-dwelling adults aged ≥60 years. METHODS: We searched EMBASE, MEDLINE, PsycINFO, Cochrane Database of Systematic Reviews, CINAHL and Evidence-Based Medicine Reviews databases in April 2023. Standard methods were used to screen, extract data, assess risk of bias (using Newcastle-Ottawa scale), provide a narrative synthesis and, where appropriate, conduct meta-analysis. RESULTS: We included 8 studies, with at least 3505 unique participants. Five found limited evidence for an association between delirium and subsequent falls: one adjusted study showed an increase in falls (risk ratio 6.66; 95% confidence interval (CI) 2.16-20.53), but the evidence was low certainty. Four non-adjusted studies found no clear effect. Three studies (one with two subgroups treated separately) found some evidence for an association between falls and subsequent delirium: meta-analysis of three adjusted studies showed an increase in delirium (pooled odds ratio 2.01; 95% CI 1.52-2.66); one subgroup of non-adjusted data found no clear effect. Number of falls and fallers were reported in the studies. Four studies and one subgroup were at high risk of bias and one study had some concerns. CONCLUSIONS: We found limited evidence for the association between delirium and falls. More methodologically rigorous research is needed to understand the complex relationship and establish how and why this operates bidirectionally. Studies must consider confounding factors such as dementia, frailty and comorbidity in their design, to identify potential modifying factors involved. Clinicians should be aware of the potential relationship between these common presentations.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
