Brief summary

A systematic review and meta-analysis of 26 studies involving 297,435 patients demonstrated that ambulating within 24 to 48 hours after hip fracture surgery significantly lowered 30-day and 1-year mortality, reduced complications, and improved functional independence.

What NurseJet pulled from the source

Evaluating 297,435 older adults, early mobilization within 24 to 48 hours postoperatively cut 30-day mortality by 60% (RR 0.40; 95% CI 0.25-0.64) and 1-year mortality by 43% (RR 0.57; 95% CI 0.40-0.80). Patients also experienced fewer postoperative complications (RR 0.79; 95% CI 0.74-0.84)—notably less pneumonia and thromboembolism—shorter hospital stays, higher rates of discharge home, and superior functional independence scores.

Why this matters for nurses

Orthopedic and geriatric nurses often encounter barriers to day-one mobilization, including patient fear, postoperative pain, hypotension, and delirium. This extensive meta-analysis provides robust evidence that overcoming these hurdles to get patients upright within 24 to 48 hours directly protects against lethal pulmonary and vascular complications.

Bedside takeaway

Ambulating older adults within 24 to 48 hours of hip fracture surgery cut 30-day mortality by 60% and significantly lowered pneumonia and thromboembolism rates.

Key takeaways

Early ambulation within 24 to 48 hours following hip fracture surgery was associated with substantial reductions in both 30-day (RR 0.40) and 1-year mortality (RR 0.57).
Postoperative complications dropped by 21% overall (RR 0.79; 95% CI 0.74-0.84), driven by lower incidences of postoperative pneumonia and venous thromboembolism.
Patients achieved higher Barthel Index and Functional Independence Measure scores, along with increased rates of direct discharge to home.
Hospital readmission rates did not differ significantly between early and delayed mobilization groups.

Practice implications

Collaborate with physical therapy and providers to initiate weight-bearing or out-of-bed ambulation within the first 24 to 48 hours after hip surgery. Premedicate for pain prior to scheduled transfers, monitor for orthostatic intolerance, and communicate the survival and functional benefits to hesitant patients and families.

Limitations & cautions

The meta-analysis synthesized 26 studies with substantial heterogeneity, predominantly relying on observational cohort designs alongside randomized trials. Mobilization definitions and assistance levels varied across institutional protocols.

Neurosurgical review (PubMed)Oct 17, 2026Systematic Review

A systematic review and meta-analysis of 14 studies comprising 7,981 patients found extending single-agent antibiotic prophylaxis beyond one day did not reduce postoperative meningitis after endoscopic endonasal skull base surgery, whereas intraoperative CSF leak significantly increased infection risk.

Postoperative meningitis is an uncommon but severe complication following endoscopic endonasal skull base surgery (EESBS). While perioperative antimicrobial prophylaxis is universally administered, the required duration remains controversial, frequently leading to prolonged, non-evidence-based antibiotic courses. Following PRISMA guidelines, researchers meta-analyzed 14 studies covering 7,981 patients receiving single-agent antibiotic prophylaxis categorized as ultra-short (≤1 day), short (1–3 days), or long (>3 days). The pooled incidence of postoperative meningitis across all cohorts was 1.38% (95% CI: 0.92%–2.08%; I² = 65.8%). Subgroup analysis showed comparable meningitis rates across duration cohorts: 1.24% for ultra-short prophylaxis (95% CI: 0.66%–2.32%), 1.20% for short prophylaxis (95% CI: 0.38%–3.70%), and 2.12% for long prophylaxis (95% CI: 0.82%–5.36%), with no statistically significant difference (p = 0.764). Meta-regression confirmed prophylaxis duration was not associated with meningitis (p = 0.487). Instead, higher study-level prevalence of intraoperative cerebrospinal fluid (CSF) leakage was significantly associated with increased meningitis rates (β = 0.0389 per percentage point; p = 0.010).

Key takeaways

Meta-analysis evaluated 14 studies including 7,981 patients undergoing endoscopic endonasal skull base surgery.
Overall postoperative meningitis incidence was 1.38% (95% CI: 0.92%–2.08%).
Meningitis rates did not differ between ultra-short ≤1 day (1.24%), short 1–3 days (1.20%), or long >3 days (2.12%) antibiotic regimens (p = 0.764).
Intraoperative CSF leakage was a significant driver of postoperative meningitis (p = 0.010), while prolonged antibiotic coverage conferred no protective benefit.

Why this matters on shift

Infection preventionists and perioperative surgical nurses champion antimicrobial stewardship by stopping surgical prophylaxis within 24 hours post-procedure. This large-scale evidence confirms that extending prophylactic antibiotics beyond 24 hours does not prevent central nervous system infections in skull base surgery and reinforces focusing post-op surveillance on intraoperative CSF leak status rather than extended antibiotic exposure.

Bedside takeaway

In 7,981 skull base surgeries, postoperative meningitis incidence was 1.38% and did not differ between ≤1 day (1.24%) and >3 days (2.12%) of antibiotics, while CSF leak was the primary infection risk.

Nursing implications

Support timely discontinuation of perioperative antibiotics within 24 hours post-op in accordance with national surgical infection prevention guidelines, maintain high clinical vigilance for signs of CSF rhinorrhea, headache, nuchal rigidity, and fever, and ensure rapid diagnostic escalation if CSF drainage is suspected.

Limitations & cautions

Included cohorts were retrospective observational studies with moderate heterogeneity (I² = 65.8%); specific antibiotic choices and dosing regimens varied across surgical centers.

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.

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.
