AI-summarized from the linked source. Educational brief, not medical advice.

Brief summary

A systematic review found that prehospital whole-blood transfusion in adults with hemorrhagic shock consistently improved shock physiology, while studies did not show a uniform mortality benefit across populations.

What NurseJet pulled from the source

Thirteen studies were included. Whole blood was associated with greater shock-index improvement and more shock reversal; overall 24-hour and 28-day mortality findings were variable, although selected high-risk and penetrating-trauma subgroups showed survival signals.

Why this matters for nurses

Emergency and trauma nurses receive patients during the handoff from prehospital resuscitation and must rapidly account for products already given, ongoing hemorrhage, response, and complications. The review supports close physiologic tracking without assuming that early improvement guarantees survival.

Bedside takeaway

At trauma handoff, reconcile prehospital whole blood and keep trending hemorrhage and perfusion despite early physiologic improvement.

How This Applies in Practice

Use this when: Receiving an adult with hemorrhagic shock who received, or may be eligible for, whole blood under an authorized trauma pathway.

On your shift

Confirm product type, unit identifiers, volume, timing, warming, vascular access, observed response, and any suspected reaction during handoff.
Continue protocol-based hemorrhage control and trend mental status, perfusion, shock measures, temperature, bleeding, and response to each resuscitation step.
Coordinate ordered sampling, blood-bank communication, massive-transfusion tracking, calcium and temperature management, and rapid escalation of deterioration.

Keep in mind: The review did not show a uniform mortality benefit or define universal eligibility. Follow the trauma protocol, facility transfusion policy, and provider orders.

Key takeaways

The review synthesized 13 studies of prehospital whole-blood use in adult hemorrhagic shock.
Physiologic measures, including shock index and shock reversal, generally favored whole blood over standard strategies.
A consistent mortality reduction was not demonstrated across the included studies.
Subgroup survival signals are hypothesis-generating and do not establish which patients should receive whole blood.

Practice implications

During trauma handoff, capture the product, volume, timing, warming method, response, and suspected transfusion reactions. Continue the hemorrhage pathway, trend perfusion and bleeding, obtain ordered samples without delaying resuscitation, and coordinate blood-bank and massive-transfusion communication.

Limitations & cautions

The 13 studies were heterogeneous and mortality findings varied. The abstract does not report a pooled overall mortality estimate or establish causal benefit, and favorable subgroup findings may be affected by selection, protocol, and survivorship differences.

Trauma, violence & abuse (PubMed)Oct 17, 2026Systematic Review

A systematic review and meta-analysis of 20 emergency department studies encompassing 7,498 women found intimate partner violence was associated with a three-fold increased risk of suicide attempt, with psychological violence showing a stronger association than physical violence.

Women experiencing intimate partner violence (IPV) and acute suicidality frequently seek medical evaluation in emergency departments (EDs), but the intersection between these two acute presentations is often overlooked during fast-paced triage. This systematic review, meta-analysis, and narrative synthesis synthesized 20 ED-based studies comprising 7,498 women across three global databases. Investigators used random-effects models and evaluated study quality with the Joanna Briggs Institute (JBI) checklist. Overall, 22% (95% CI: 11%–36%) of women presenting to the ED for suicide-related care had a history of physical IPV, while 13% (95% CI: 8%–18%) of women with known IPV histories reported active suicidality. A history of IPV was associated with a three-fold increase in the risk of suicide attempt (risk ratio [RR] 3.00; 95% CI: 1.39–6.47). Notably, psychological IPV demonstrated a stronger association with suicide risk (RR 3.23; 95% CI: 1.68–6.19) than physical IPV alone (RR 2.00; 95% CI: 1.26–3.17).

Key takeaways

Systematic review synthesized 20 emergency department studies encompassing 7,498 women.
Nearly 1 in 4 women (22%; 95% CI: 11%–36%) presenting to the ED with suicidality had experienced physical IPV.
IPV was associated with a three-fold higher risk of suicide attempt (RR 3.00; 95% CI: 1.39–6.47).
Psychological IPV showed a higher risk ratio for suicide attempts (RR 3.23; 95% CI: 1.68–6.19) than physical IPV (RR 2.00; 95% CI: 1.26–3.17).

Why this matters on shift

Emergency nurses are the primary healthcare professionals conducting universal triage, suicide risk screening (e.g., C-SSRS), and domestic violence assessments. Recognizing that nearly one-quarter of suicidal female presentations co-occur with IPV—and that non-physical, psychological abuse carries an even higher relative risk for suicide attempt—demands that ED nursing assessments integrate trauma-informed safety planning rather than treating suicidality and relationship violence in isolation.

Bedside takeaway

In an ED meta-analysis of 7,498 women, intimate partner violence tripled suicide attempt risk (RR 3.00), with psychological IPV (RR 3.23) linked more strongly than physical IPV (RR 2.00).

Nursing implications

Conduct routine IPV and suicide screenings privately away from companions or visitors, assess for emotional and psychological coercion even when physical injury is absent, and connect patients showing combined risk immediately to hospital social work, victim advocacy, and safe crisis intervention pathways.

Limitations & cautions

High between-study heterogeneity across meta-analytic models (I² > 75%); high risk of bias identified in half of the included primary studies; relied largely on cross-sectional self-reported survey measures.

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.
