Brief summary

A systematic review and meta-analysis of 22 randomized trials involving 1,522 ICU patients reported that sensory stimulation improved measured consciousness and reduced delirium incidence and duration compared with routine care.

What NurseJet pulled from the source

The pooled delirium-incidence estimate favored sensory stimulation (OR 0.33), and the review also reported shorter delirium duration and awakening time. Subgroup analyses favored multisensory over single-modality approaches, family-delivered over nurse-delivered stimulation, at least seven days of intervention, and twice-daily delivery, but these subgroup findings require cautious interpretation.

Why this matters for nurses

ICU nurses repeatedly assess arousal, cognition, delirium, sleep-wake patterns, and tolerance of family interaction. A structured sensory plan may complement the unit's delirium-prevention bundle, but it should be individualized and coordinated rather than added as unstructured stimulation.

Bedside takeaway

Structured sensory stimulation may complement ICU delirium care, but the pooled intervention protocols varied.

How This Applies in Practice

Use this when: Planning orientation or sensory engagement for an ICU patient who is eligible under the unit's delirium-prevention pathway.

On your shift

Confirm the patient's arousal, delirium, communication, hearing, vision, and physiologic tolerance before the session.
Coordinate approved sensory cues with rest periods, mobility, sedation goals, and family participation.
Document the intervention and response and stop or escalate for distress, agitation, or physiologic intolerance.

Keep in mind: The pooled studies used varied protocols, and subgroup findings are exploratory rather than a fixed prescription. Follow the delirium protocol, facility policy, and provider orders.

Key takeaways

The review pooled 22 randomized trials involving 1,522 ICU patients.
Sensory stimulation was associated with improved measured consciousness and lower delirium incidence.
Pooled analyses also favored sensory stimulation for delirium duration and awakening time.
Subgroup findings suggested that modality, delivery person, duration, and frequency may influence results.

Practice implications

For an eligible patient, use the unit-approved delirium and stimulation plan, coordinate timing with rest and other care, and document the patient's response. Include family only through the established orientation and safety process, and stop or escalate when stimulation causes distress or physiologic intolerance.

Limitations & cautions

The abstract does not report the certainty of evidence, between-study heterogeneity, named measurement scales, or full results for mechanical ventilation. Interventions varied across modality, provider, frequency, and duration, and subgroup comparisons should not be treated as definitive prescriptions.

Western journal of nursing research (PubMed)Oct 15, 2026Systematic Review

A systematic review and meta-analysis of 38 studies including 19,033 patients identified clinical severity scales—specifically Modified Fisher grade and Fisher grade—and hemodynamic status as the strongest predictors of cerebral vasospasm following subarachnoid hemorrhage.

Emergency ICUAI summaryReview source

Systematic ReviewResearchQuality ImprovementAI summary · original source linked below

Cerebral vasospasm is a severe complication of aneurysmal subarachnoid hemorrhage (SAH) that frequently precipitates delayed cerebral ischemia and increases patient mortality. To clarify clinical predictors and inform intensive care nursing assessments, investigators conducted a systematic review and meta-analysis across eight databases through August 2024, evaluating study quality with the Joanna Briggs Institute checklist and Risk of Bias 2.0 tool. Across 38 included studies (27 in the meta-analysis) encompassing 19,033 patients, clinical severity metrics showed the strongest association with cerebral vasospasm: Modified Fisher grade (odds ratio [OR] 2.88; 95% CI, 2.04–4.07), Fisher grade (OR 2.27; 95% CI, 1.91–2.69), and hemodynamic status (OR 2.56; 95% CI, 1.17–5.59). Aneurysm-related characteristics and comorbid conditions were also linked to increased vasospasm risk, whereas clinical biomarkers and inflammatory markers demonstrated comparatively smaller effect sizes.

Key takeaways

Systematic review and meta-analysis synthesized 38 studies (27 in meta-analysis) encompassing 19,033 patients after subarachnoid hemorrhage.
Radiographic and clinical severity scales showed the strongest association with cerebral vasospasm: Modified Fisher grade (OR 2.88; 95% CI, 2.04–4.07) and Fisher grade (OR 2.27; 95% CI, 1.91–2.69).
Hemodynamic instability was strongly associated with vasospasm risk (OR 2.56; 95% CI, 1.17–5.59).
Aneurysm features and comorbidities also increased risk, while clinical biomarkers and inflammatory markers demonstrated smaller effect sizes.

Why this matters on shift

Neurocritical care nurses are the first line of defense in detecting subtle neurological deterioration and hemodynamic shifts in patients hospitalized for subarachnoid hemorrhage. Understanding that initial Fisher grade and hemodynamic status carry the highest statistical odds for vasospasm reinforces rigorous serial neurological scoring and strict blood pressure monitoring during the peak vasospasm window.

Bedside takeaway

In a meta-analysis of 19,033 SAH patients, Modified Fisher grade (OR 2.88), Fisher grade (OR 2.27), and hemodynamic status (OR 2.56) were the strongest predictors of cerebral vasospasm.

Nursing implications

Identify admission Fisher or Modified Fisher scores during shift handoff, maintain strict hemodynamic parameters per provider orders, and immediately escalate focal neurological deficits, altered sensorium, or transcranial Doppler velocity increases.

Limitations & cautions

Synthesized observational studies with heterogeneous definitions and reporting standards; meta-analysis reflects statistical associations rather than prospective causal prediction models; abstract does not detail specific individual biomarker cutoff values.

Natriuresis-guided loop diuretic titration uses spot urinary sodium measurements to tailor decongestive therapy in acute heart failure (AHF). In this sex-specific analysis of the randomized PUSH-AHF trial, investigators evaluated 310 patients (45% women) assigned to natriuresis-guided therapy versus standard of care. In men, natriuresis-guided therapy produced significantly greater mean 24-hour total natriuresis compared with standard care (443 vs 354 mmol, p = 0.004), whereas women showed no significant difference between treatment arms (357 vs 336 mmol, p = 0.533; adjusted p-interaction = 0.276). Notably, the median 24-hour natriuretic response per milligram of loop diuretic (bumetanide equivalents) was significantly lower in women receiving natriuresis-guided therapy than standard care (23 vs 52 mmol/mg, p = 0.001), while no difference was observed in men (38 vs 45 mmol/mg, p = 0.337; adjusted p-interaction = 0.009). Clinically, natriuresis guidance was associated with a 49% lower risk of 180-day all-cause mortality or HF rehospitalization in men (adjusted HR 0.51; 95% CI, 0.30–0.86; p = 0.011), but showed no benefit in women (adjusted HR 1.40; 95% CI, 0.67–2.91; p = 0.368; adjusted p-interaction = 0.026).

Key takeaways

Sex-specific analysis of the PUSH-AHF randomized trial evaluated 310 patients (45% women) with acute heart failure.
In men, natriuresis-guided therapy increased 24-hour urinary sodium excretion (443 vs 354 mmol, p = 0.004) and reduced 180-day mortality/rehospitalization by 49% (adjusted HR 0.51, p = 0.011).
In women, natriuresis guidance did not increase total natriuresis (357 vs 336 mmol, p = 0.533) or improve 180-day clinical outcomes (adjusted HR 1.40, p = 0.368; p-interaction = 0.026).
Women in the guided arm exhibited a blunted natriuretic response per milligram of loop diuretic (23 vs 52 mmol/mg bumetanide, p = 0.001).

Why this matters on shift

Cardiology and telemetry nurses frequently manage intensive loop diuretic infusions and collect spot urinary sodium samples during acute decompensated heart failure admissions. These findings demonstrate that diuretic responsiveness and natriuresis-guided protocols may operate differently by biological sex, warning clinicians that intensifying diuretic doses based solely on spot sodium targets may not yield uniform decongestive or prognostic benefits across all patient groups.

Bedside takeaway

In the PUSH-AHF trial (310 patients), natriuresis-guided diuretic therapy reduced 180-day mortality/readmission in men (aHR 0.51) but showed no benefit in women (aHR 1.40; p-interaction=0.026).

Nursing implications

Collect urine samples for spot sodium strictly at ordered intervals during acute decongestion, maintain accurate intake/output records, monitor serum electrolytes and renal function closely during diuretic uptitration, and recognize that blunted urinary sodium output in female patients may reflect altered pharmacodynamics rather than simple noncompliance with fluid restrictions.

Limitations & cautions

Post-hoc subgroup analysis of a randomized trial with limited sample size (n = 310, including 139 women); findings are hypothesis-generating and require prospective validation in sex-stratified clinical trials before modifying clinical guidelines.

A multicenter randomized controlled trial across three hospitals found that deploying specialized nurse communication facilitators during and after an ICU admission did not reduce family member depressive symptoms over 6 months.

ICU Med-SurgAI summaryReview source

Family members of critically ill patients frequently experience severe psychological distress, fragmented communication during handoffs, and difficulties achieving care aligned with patient values. This multicenter randomized controlled trial evaluated a structured nurse communication facilitator intervention across three hospitals in Seattle, Washington. Investigators enrolled 449 ICU patients with chronic life-limiting illness or high hospital mortality risk (>15%) and 505 family members, randomized at the patient level to standard care (n = 224) or intervention (n = 225). Nurse communication facilitators were trained to support, model, and coach communication strategies to promote goal-concordant care throughout the ICU stay and for three months post-randomization. The primary outcome was family member depression measured by the Hospital Anxiety and Depression Scale (HADS) over six months. Mean HADS-depression scores declined over time in both groups (baseline 7.2 vs 5.9 at 6 months), with no statistically significant difference between groups (mean difference -0.07; 95% CI -0.70 to 0.55). Small secondary improvements favored the intervention for relationship with the healthcare team (p = 0.0162) and goal concordance (p = 0.0504), but effect sizes were modest.

Key takeaways

Multicenter trial randomized 449 critically ill patients and 505 family members across three hospital centers.
Dedicated nurse communication facilitators engaging families for 3 months post-ICU did not significantly reduce 6-month depression (difference -0.07; 95% CI -0.70 to 0.55).
Family depressive symptoms declined equally over time in both intervention and standard care arms (from 7.2 to 5.9).
Secondary endpoints showed modest positive gains in relationship with the care team (p = 0.0162) and goal concordance (p = 0.0504).

Why this matters on shift

ICU bedside nurses invest substantial time providing emotional support and interpreting complex clinical updates for grieving families. This rigorous trial demonstrates that standalone nurse communication facilitators do not prevent post-intensive care depression, indicating that psychological morbidity requires broader multidisciplinary mental health support rather than communication coaching alone.

Bedside takeaway

In a multicenter RCT of 505 family members of ICU patients, nurse communication facilitators did not reduce 6-month depression scores (-0.07 difference, 95% CI -0.70 to 0.55), despite modest gains in team trust.

Nursing implications

Maintain empathetic, goal-aligned bedside communication during daily interprofessional rounds, but recognize the limits of communication interventions alone in preventing family depression; advocate for early palliative care, social work, and formal psychological support referrals for high-distress families.

Limitations & cautions

Conducted within a single regional health system; high attrition in questionnaire response rates at 6 months; baseline depression scores were relatively mild, potentially limiting the detectable margin of improvement.
