Brief summary

In a multicenter cross-sectional study of 415 residents across 33 German nursing homes, trained-nurse screening identified probable delirium in 17.6% of residents, and 43.1% of those screening positive had a nonmotor presentation.

What NurseJet pulled from the source

Delirium is well studied in hospitals but primary prevalence data from nursing homes are limited. In this multicenter cross-sectional study, trained nurses collected data during a 2-week period in April 2024 from a randomly sampled group of residents aged 65 or older. The analysis included 415 residents across 33 German nursing homes. Using a 4 'A's Test (4AT) score of 4 or higher, 17.6% of residents screened as having probable delirium (95% CI 13.4 to 22.7). Among residents who screened positive, the Delirium Motor Subtype Scale classified 43.1% as nonmotor, 25.0% as hypoactive, 18.1% as hyperactive, and 13.9% as mixed. Factors independently associated with probable delirium included more severe neuropsychiatric symptoms (adjusted OR 1.17), observed pain behavior (adjusted OR 3.67), a dementia diagnosis (adjusted OR 2.01), and residence in the home for at least 25 months (adjusted OR 2.74). The authors concluded that delirium is a substantial nursing-home issue and called for better detection, prevention training, and routine use of brief screening tools by nurses.

Why this matters for nurses

Delirium can be missed when a resident is not agitated, and this study found that nonmotor and hypoactive presentations together made up most positive screens. This matters for geriatric nurses because a substantial share of residents screened positive and pain behavior, dementia, and longer residence helped identify groups needing closer attention.

Bedside takeaway

Be aware that trained-nurse screening found probable delirium in 17.6% of residents across 33 nursing homes, with nonmotor presentations most common, so a quiet resident can still screen positive.

Key takeaways

Trained nurses screened 415 residents across 33 nursing homes, and 17.6% met the 4AT threshold for probable delirium (95% CI 13.4 to 22.7).
Nonmotor delirium was the largest subtype among positive screens (43.1%), followed by hypoactive (25.0%), hyperactive (18.1%), and mixed (13.9%) presentations.
Observed pain behavior was associated with higher odds of probable delirium (adjusted OR 3.67, 95% CI 1.51 to 8.93), as were dementia and longer residence.
The authors support routine brief nurse screening and stronger delirium-detection and prevention training in nursing homes.

Practice implications

For nurses in long-term care, the findings support consistent use of the facility-approved brief delirium screen and attention to quieter changes in cognition, alertness, and behavior, not only agitation. A positive 4AT screen indicates probable delirium and should trigger the local assessment and escalation pathway rather than being treated as a confirmed diagnosis by itself.

Limitations & cautions

This was a 2-week cross-sectional snapshot in German nursing homes, so it estimates prevalence rather than incidence and cannot show that associated factors caused delirium. The 4AT is a screening tool rather than a diagnostic interview, and excluding residents with aphasia, coma, deafness, end-of-life status, or insufficient German may limit generalizability and bias the estimate.

Postoperative delirium (POD) is a common, distressing complication in older surgical patients, yet effective pharmacologic prevention options remain limited. This systematic review and meta-analysis of 25 randomized controlled trials (RCTs) involving 3,344 patients evaluated perioperative administration of ketamine (9 trials) and esketamine (16 trials) compared to placebo or standard care. Both agents were associated with reduced POD incidence (ketamine: risk ratio [RR] 0.69; 95% CI, 0.49–0.98; P = .04; esketamine: RR 0.58; 95% CI, 0.36–0.95; P = .03). Risk reductions were most evident with higher-dose regimens (single bolus: ketamine >0.5 mg/kg or esketamine >0.25 mg/kg; cumulative dose: ketamine >1.0 mg/kg or esketamine >0.5 mg/kg), bolus-plus-infusion administration, and in major surgical procedures. However, the preventative association was present only when delirium was assessed between postoperative days 2 and 7, not within the first 24 hours. Furthermore, ketamine/esketamine significantly increased the risk of postoperative dizziness (RR 1.45; 95% CI, 1.14–1.84; P = .002). Trial sequential analysis indicated that total evidence remains inconclusive due to insufficient overall sample size.

Key takeaways

Meta-analysis analyzed 25 RCTs with 3,344 patients receiving perioperative ketamine (9 trials) or esketamine (16 trials).
Both agents were associated with lower POD incidence versus control: ketamine RR 0.69 (P = .04) and esketamine RR 0.58 (P = .03).
Delirium reduction was apparent at postoperative days 2 to 7, but not during the initial 24 hours.
Dizziness risk was significantly elevated in treated patients (RR 1.45; 95% CI, 1.14–1.84; P = .002), and trial sequential analysis found cumulative sample size insufficient to draw definitive conclusions.

Why this matters on shift

Surgical and post-anesthesia nurses monitor older adults recovering from general anesthesia for confusion, agitation, and fall risk. While ketamine and esketamine show potential neurocognitive protective signals beyond day 1, their heightened dizziness profile increases post-op balance instability, requiring cautious bedside mobility precautions rather than unreserved clinical adoption.

Bedside takeaway

In a meta-analysis of 25 RCTs (3,344 patients), perioperative ketamine (RR 0.69) and esketamine (RR 0.58) reduced delirium at days 2–7 but significantly increased dizziness (RR 1.45).

Nursing implications

Screen surgical patients systematically for emergence and delayed delirium using validated tools (such as CAM or CAM-ICU) through postoperative day 7, implement strict fall and dizziness precautions when ketamine derivatives are administered, and avoid assuming early alertness guarantees absence of delayed delirium.

Limitations & cautions

Trial sequential analysis confirmed current evidence remains inconclusive due to inadequate total information size; dizziness was increased (RR 1.45); high heterogeneity in surgical populations and anesthesia protocols.

Stroke (PubMed)Oct 1, 2026Clinical Guideline

The American Heart Association and American Stroke Association released updated 2026 guidelines for adult stroke rehabilitation and recovery, updating guidance across medical comorbidities, bone health, fall risk, and technology-assisted therapy.

Emergency Med-SurgAI summaryReview source

Clinical GuidelineGuidelineQuality ImprovementWorkflowAI summary · original source linked below

Replacing the previous 2016 recommendations, the American Heart Association and American Stroke Association published the comprehensive 2026 Guideline for Adult Stroke Rehabilitation and Recovery following extensive systematic review of literature published through late 2025. Directed toward interprofessional care teams, rehabilitation nurses, therapists, and family caregivers, the updated guideline establishes evidence-based standards spanning the inpatient acute-to-community recovery continuum. Major updates focus on the comprehensive assessment and management of vascular and medical comorbidities, structured fracture risk assessment, protocolized inpatient and home fall prevention, technology-enabled rehabilitation modalities, dedicated caregiver psychosocial support, community participation, and standardized evaluations for safe return to driving and employment.

Key takeaways

AHA/ASA 2026 guideline replaces 2016 standards across the inpatient and outpatient stroke rehabilitation continuum.
Establishes new recommendations for managing post-stroke medical comorbidities, bone mineral density loss, and fracture prevention.
Prioritizes structured fall prevention protocols and evaluates technology-enabled rehabilitation systems.
Expands dedicated guidance on family caregiver support, functional community participation, and safe return to driving.

Why this matters on shift

Neuroscience and medical-surgical nurses manage acute stroke survivors during the highest-risk window for post-stroke complications, including immobility, deconditioning, and falls. Updated national guidance gives bedside nurses clear authority to initiate early mobility safety assessments, safeguard bone health, and prepare family caregivers for post-discharge recovery demands.

Bedside takeaway

AHA/ASA updated its adult stroke rehabilitation guideline, emphasizing comorbidity management, bone health, structured fall prevention, technology-enabled therapies, and caregiver support.

Nursing implications

Incorporate structured fall risk assessments and fracture prevention strategies into post-stroke care plans, assess family caregiver burden early in the hospital stay, and coordinate closely with physical and occupational therapy on mobility goals and discharge equipment needs.

Limitations & cautions

Comprehensive guideline covers broad multi-domain stroke rehabilitation; the authors emphasize that substantial gaps in high-certainty evidence remain for specific neuro-recovery interventions, underscoring the need for ongoing randomized trials.

Worldviews on evidence-based nursing (PubMed)Oct 1, 2026Systematic Review

A systematic review and meta-analysis of hospital sensor-based fall prevention systems found no significant overall reduction in falls or injuries, but machine-learning systems and mandatory implementation significantly lowered fall rates.

Med-Surg GeriatricsAI summaryReview source

Hospital falls remain a pervasive cause of patient injury, extended length of stay, and nursing alarm fatigue. This systematic review and meta-analysis synthesized evidence from 16 interventional studies (seven pooled in meta-analysis) across MEDLINE, Embase, CINAHL, CENTRAL, and Web of Science evaluating sensor-based fall prevention technologies in hospital units. Using random-effects models with the Paule-Mandel estimator and Hartung-Knapp-Sidik-Jonkman adjustment, sensor systems overall demonstrated no statistically significant reduction in fall rates (incidence rate ratio [IRR] 0.77; 95% CI 0.38–1.58; I² = 92%), number of fallers (odds ratio 1.24; 95% CI 0.76–2.02; I² = 73%), or fall-related injuries (IRR 0.98; 95% CI 0.81–1.18; I² = 0%). However, subgroup analysis revealed that advanced machine learning-based sensor systems significantly reduced fall rates (IRR 0.50; 95% CI 0.32–0.79), whereas conventional rule-based sensors showed no effect. Mandatory unit-wide implementation was also associated with significantly reduced fall rates (IRR 0.51; 95% CI 0.37–0.70). Overall GRADE evidence certainty ranged from very low to low.

Key takeaways

Meta-analysis of 16 hospital studies found sensor-based fall systems overall did not significantly reduce fall rates (IRR 0.77) or injuries (IRR 0.98).
Machine learning-based sensor systems significantly cut inpatient fall rates by 50% (IRR 0.50, 95% CI 0.32–0.79).
Traditional rule-based pressure sensors showed no significant benefit on fall incidence.
Mandatory unit-wide sensor implementation was associated with a significant fall rate reduction (IRR 0.51, 95% CI 0.37–0.70), but not fewer fallers.

Why this matters on shift

Hospital bed and chair alarms are ubiquitous on med-surg and geriatric units, but frequently generate high false-alarm burdens and alert fatigue without clearly preventing patient harm. Demonstrating that conventional sensors fail to reduce falls while AI/machine-learning systems and unit-wide compliance halve fall rates informs hospital technology investments and nursing safety protocols.

Bedside takeaway

A meta-analysis found hospital sensor alarms overall did not reduce falls (IRR 0.77) or injuries (IRR 0.98), though machine-learning sensors significantly reduced fall rates by 50% (IRR 0.50).

Nursing implications

Do not rely on standard pressure sensor alarms as standalone fall prevention; pair technology with intentional rounding, assisted toileting, and environmental safety checks. When modern predictive or machine-learning sensors are deployed, adhere strictly to unit operational protocols to realize preventative benefits.

Limitations & cautions

High statistical heterogeneity among included trials (I² up to 92%); only seven studies eligible for statistical pooling; overall certainty of evidence rated very low to low under GRADE criteria.
