1. Positive communication for decreasing burnout in intensive-care-unit staff: a cluster-randomized trial.
In a pragmatic, multicountry cluster-RCT across 370 ICUs, a 4-week positive communication intervention significantly reduced burnout prevalence from 63.3% to 52.2% compared with usual care (adjusted OR 0.56). Emotional exhaustion and depersonalization decreased, with parallel gains in personal accomplishment, job satisfaction, and perceived safety and ethical climate.
Impact: This is one of the largest randomized organizational interventions in critical care demonstrating scalable reduction in burnout with meaningful downstream cultural benefits.
Clinical Implications: ICUs can implement a brief, low-cost, team-focused positive communication program to reduce burnout and improve workplace climate, likely benefiting staff well-being and patient-centered care.
Key Findings
- Burnout prevalence decreased from 63.3% to 52.2% in the intervention arm (adjusted OR 0.56; 95% CI 0.46-0.68; P<0.001).
- Emotional exhaustion and depersonalization scores were lower, and personal accomplishment higher, in the intervention arm.
- Secondary benefits included improved job satisfaction, perceived safety, ethical climate, and reduced intention to leave.
Methodological Strengths
- Large, international cluster-randomized design with pragmatic implementation across 370 ICUs in 60 countries.
- Prespecified primary outcome using validated Maslach Burnout Inventory; trial registered (NCT06453616).
Limitations
- Short intervention period (4 weeks) and immediate post-intervention assessment may not capture durability.
- Self-reported outcomes and potential contamination between groups in multicenter settings.
Future Directions: Evaluate long-term sustainability, cost-effectiveness, and integration with broader well-being programs; test adaptations in resource-limited settings.
PURPOSE: Occupational burnout is common among intensive-care-unit (ICU) staff and adversely affects staff well-being and patient care. We hypothesized that a multicomponent intervention based on organizational support and workplace climate improvement would reduce burnout. METHODS: The 1:1 cluster-randomized Hello trial involved 370 ICUs from sixty countries allocated to either the intervention or usual care. The four-week intervention designed to promote a positive workplace culture and within-team support used posters, email nudges, greetings during morning meetings, role modeling, and positive messages in boxes and on noticeboards. The primary endpoint was burnout prevalence, measured using the Maslach Burnout Inventory. Secondary outcomes included MBI subscale scores, well-being, job satisfaction, ethical climate, intention to leave, work safety, and professional conflicts. RESULTS: Before the intervention, burnout prevalence was 59.4% (95% CI, 58.6-60.5), with no difference between arms. After the intervention, 4966 intervention-arm and 4602 control-arm healthcare professionals completed the MBI. Burnout prevalence was significantly lower in the intervention arm relative to controls (52.2% vs. 63.3%; adjusted odds ratio, 0.56; 95%CI 0.46-0.68; P < 0.001). Among MBI sub-scales scores, emotional exhaustion and depersonalization were lower, and personal accomplishment was higher in the intervention arm. Staff in the intervention arm reported better job satisfaction, workplace safety, ethical climate, and patient- and family-centered care; they were less often considering a job change. CONCLUSIONS: The Hello intervention reduced burnout and improved workplace culture among ICU staff. Given the pragmatic design, the intervention tested may have broad applicability. TRIAL REGISTRATION: The trial was registered on ClinicalTrials.gov on June 18, 2024 (NCT06453616).
2. Ultrasound-guided fascia iliaca compartment block versus intravenous analgesia in geriatric hip fractures: a systematic review and meta-analysis of randomized trials demonstrating superior pain control.
Across 26 randomized trials, ultrasound-guided fascia iliaca compartment block yielded better and more sustained pain relief than intravenous analgesia in elderly hip fracture patients, while reducing opioid-related adverse events and improving satisfaction. Findings support UG-FICB as first-line analgesia in geriatric hip fracture pathways.
Impact: This synthesis consolidates randomized evidence favoring a regional anesthesia strategy that reduces opioid exposure and complications in a high-risk geriatric population.
Clinical Implications: Adopt UG-FICB as first-line analgesia for geriatric hip fractures in prehospital and perioperative pathways to improve pain control, reduce opioid requirements and GI/respiratory side effects, and enhance patient satisfaction.
Key Findings
- UG-FICB provided superior and sustained reductions in VAS pain scores versus IV analgesia across included RCTs.
- Opioid consumption and opioid-related adverse events (notably GI events) were lower with UG-FICB.
- Patient satisfaction was higher with UG-FICB; safety profile favored regional analgesia without increase in respiratory adverse events.
Methodological Strengths
- Systematic review and meta-analysis restricted to randomized controlled trials with comprehensive bilingual database coverage.
- Standard meta-analytic methods (random/fixed-effects) with prespecified primary and secondary outcomes.
Limitations
- Heterogeneity in block techniques, local anesthetic regimens, and timing across RCTs.
- Incomplete reporting of secondary outcomes and potential publication bias cannot be excluded.
Future Directions: Head-to-head trials evaluating UG-FICB versus alternative regional blocks and standardized protocols; implementation studies in prehospital systems and EDs.
BACKGROUND: Severe pain in elderly hip fracture patients exacerbates perioperative risks. This meta-analysis compares ultrasound-guided fascia iliaca compartment block (UG-FICB) with intravenous analgesia for pain management. METHODS: A comprehensive search of randomized controlled trials (RCTs) published through February 2025 was conducted across major databases, including English-language databases and Chinese databases. Outcomes analyzed via RevMan 5.3 using random/fixed-effect models. Primary outcomes encompassed Visual Analog Scale (VAS) scores, analgesic consumption, patient satisfaction, main adverse reactions, and gastrointestinal adverse events. Secondary outcomes included intraoperative blood loss, operative time, length of stay, and respiratory adverse events. RESULTS: A total 26 RCTs ( CONCLUSION: Compared to intravenous analgesia, UG-FICB provides superior, sustained pain relief with fewer opioid-related complications and higher patient satisfaction. UG-FICB's safety and efficacy advantages strongly support its adoption as first-line therapy in geriatric hip fractures protocols.
3. Comparison of midazolam and dexmedetomidine on postoperative delirium in older patients undergoing total knee replacement under spinal anesthesia.
In a double-blind RCT of 175 older patients under spinal anesthesia for TKA, dexmedetomidine halved postoperative delirium compared with midazolam (13.9% vs 27.4%), with better sedation quality and fewer sedation failures. Pain scores and complication rates were similar between groups.
Impact: Provides randomized evidence to optimize intraoperative sedation to prevent POD in elderly patients undergoing orthopedic surgery under regional anesthesia.
Clinical Implications: Prefer dexmedetomidine over midazolam for intraoperative sedation during spinal anesthesia in older adults at risk of delirium; maintain vigilance for hemodynamic effects while leveraging improved sedation quality.
Key Findings
- POD incidence: dexmedetomidine 13.9% vs midazolam 27.4% (P=0.045).
- Dexmedetomidine achieved better sedation quality and lower sedation failure rates (P=0.007 and P=0.018).
- Postoperative pain intensity and complication rates did not differ between groups.
Methodological Strengths
- Prospective, double-blind, randomized parallel-group design with prespecified outcomes and trial registration (KCT0006587).
- Standardized delirium assessment (CAM) over five postoperative days.
Limitations
- Single-center study with moderate sample size; may limit generalizability.
- Hemodynamic adverse effects were not detailed; longer-term cognitive outcomes were not assessed.
Future Directions: Multicenter trials to validate findings across surgical populations and to evaluate hemodynamic safety and long-term cognitive outcomes.
BACKGROUND: Postoperative delirium (POD) is a frequent and serious complication in older patients undergoing orthopedic surgery. This study aimed to compare the effects of midazolam and dexmedetomidine on the incidence of POD in elderly patients undergoing total knee arthroplasty under spinal anesthesia. METHODS: In this prospective, double-blind, randomized, parallel group comparative trial, a total of 175 patients aged 65 years or older were allocated to receive either midazolam or dexmedetomidine for intraoperative sedation. The primary outcome was the incidence of POD, evaluated using the confusion assessment method for five postoperative days. Secondary outcomes included the quality of sedation, incidence of sedation failure, postoperative analgesic profiles, and complication rates. RESULTS: The incidence of POD was significantly lower in the dexmedetomidine group compared to the midazolam group (13.9% vs. 27.4%, P = 0.045). In addition, dexmedetomidine was associated with superior sedation quality and a significantly lower rate of sedation failure (P = 0.007 and P = 0.018, respectively). Postoperative pain intensity and complication rates were comparable between the two groups. CONCLUSION: Dexmedetomidine significantly reduced the incidence of POD and improved sedation quality compared to midazolam. These findings suggest that dexmedetomidine may be a preferable sedative for elderly patients undergoing total knee arthroplasty under spinal anesthesia. TRIAL REGISTRATION: This study was registered with the WHO International Clinical Trials Registry Platform (Trial number: KCT0006587, Registration date: 16th September 2021).
