1 · What the graph read from it

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.

2 · The registry

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

backgroundWhile medication is a recognized risk factor of delirium, there is currently a lack of detailed information on managing and preventing medication-induced cases.

aimThis review summarizes the information provided in neurology guidelines on medication-induced delirium in patients with and without dementia to inform guidance on prevention and management strategies.

methodA systematic literature review was conducted across 114 neurological and medical organisations, Guideline Central and PubMed. Guidelines, consensus guidelines, white papers, frameworks, protocols, standard procedures, action plans and strategic documents detailing the prevention and management of medication-induced delirium in adults with or without dementia were included. Title and full-text screening was completed independently by two reviewers using PICOS. AGREE II was used to assess reporting quality. A data extraction tool was designed based on the Cochrane Effective Practice and Organization of Care Review Group (EPOC) checklist and a mixed methods approach to synthesis adopted. The systematic review protocol was registered with International Prospective Register of Systematic Reviews (PROSPERO) [ID: CRD42022366025].

resultsOut of 143 guidelines identified, 30 were included. Information for 140 individual medications was extracted. Medications most frequently cited included sedatives (n = 24/80%), opioids (n = 22/73,3%), psychoactive drugs (n = 21/70%) + anti-convulsants (n = 14/46,7%), anti-cholinergic agents (n = 20/66,7%), antihistamines (n = 18/60%), and steroids (n = 16/53,3%). Despite a consistently high-quality rating (n = 19, 63,3%), the detail provided often lacks specificity about pharmacological mechanisms, individual risk, dosing instructions, associated symptoms, therapeutic alternatives and avoidable drug-drug combinations. In relation to dementia, detailed information on the use of antipsychotics, cholinesterase inhibitors and benzodiazepines was extracted. No papers were excluded based on their quality.

conclusionNo single guideline contains enough information on the risk, prevention, and management of medication-induced delirium to sufficiently support clinical decision making.
