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

backgroundPostoperative delirium (POD) frequently occurs in elderly patients after major orthopedic surgery. Nurses play a key role in delivering non-pharmacological preventive interventions, but the evidence supporting their effectiveness varies. This systematic review aims to summarize current research on nursing interventions designed to reduce POD in older adults undergoing these surgeries.

methodsWe followed PRISMA 2020 guidelines to conduct a systematic search in five databases (CINAHL, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Google Scholar (as a supplementary source)) for studies published from 2010 to 2025. Eligible studies evaluated nursing-led interventions targeting delirium prevention in patients aged 65 years or older after major orthopedic surgery. Two reviewers independently screened using Rayyan [10] 529 records, reviewed full texts, and extracted data on study design, participants, interventions, and outcomes. Due to heterogeneity, a narrative synthesis approach was employed to analyze the data. Quality assessment used the Cochrane RoB 2 tool for randomized controlled trials and ROBINS-I [12] for non-randomized studies.

resultsEight studies met inclusion criteria, including 3,018 participants. The designs comprised two randomized controlled trials, three quasi-experimental or cohort studies, two retrospective analyses, and one before-and-after study. Nurse-led multicomponent protocols, system-level interventions such as standardized orders, and single-component approaches like sensory aid management all showed statistically significant reductions in POD incidence. Absolute risk reductions ranged from 4.0% to 24.5%. Larger trials reported modest but statistically significant effects (for example, an odds ratio of 0.59 in an orthopedic subgroup), while smaller studies observed larger decreases. Variations in intervention types and outcome measures prevented meta-analysis.

conclusionsNursing interventions, especially multicomponent protocols and systemic changes, may reduce postoperative delirium in older adults undergoing major orthopedic surgery. Even targeted single-component interventions suggest a potential to lower delirium rates meaningfully. Standardizing outcome measures in future studies would help enable outcome measures to enable meta-analyses and explore how best to implement these interventions in clinical settings.
