Outcomes associated with older patients who present or develop delirium in the emergency department: protocol for a systematic review and meta-analysis.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDelirium is commonly observed in older patients who are admitted to the emergency department (ED). Previous systematic reviews have identified poor outcomes associated with delirium in surgical, intensive care and other hospital settings, yet none have specifically considered the ED. This systematic review aims to examine associations between older patients who present or develop delirium in the ED and adverse outcomes within the hospital and after discharge. METHODS AND ANALYSIS: Searches will be conducted in MEDLINE, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library. There will be no date or language restrictions. Key terms will include concepts related to delirium, the ED and older adults. Observational studies or non-intervention clinical studies will be included that compare outcomes in older patients (ie, ≥65 years) with and without delirium. Outcomes of interest will include length of hospital stay, non-home discharge (eg, nursing home/residential aged care facility), cognitive impairment, decreased physical function, mortality, readmission to hospital and quality of life measures. Two reviewers will independently screen the studies. Data extraction and quality assessment will be extracted by one reviewer and checked by a second reviewer, with any disagreements resolved by discussion or by a third reviewer. Where appropriate, data will be combined in a meta-analysis and a GRADE assessment will be made for each outcome. All methods will be guided by the Cochrane Handbook and the Centre for Reviews and Dissemination and reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis statement as well as the recommendations set out by the Meta-analysis Of Observational Studies in Epidemiology group. ETHICS AND DISSEMINATION: As this systematic review will use published data, ethical approval is not required. The results will be disseminated through a peer-reviewed publication and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42024594975.
