Short-course versus prolonged-course antibiotic regimens for ventilator-associated pneumonia: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Current guidelines recommend short-duration antibiotic therapy for non-fermenting gram-negative bacilli (NF-GNB) ventilator-associated pneumonia (VAP) which may be associated with a higher recurrence of pneumonia. In this meta-analysis, we aimed to compare short- versus prolonged-course antibiotic regimens for VAP. METHODS: We searched several databases for randomized controlled trials (RCTs) that compared the effectiveness of a short- versus long-course of antibiotic treatment in patients with VAP. Data analysis was performed using RevMan 5.4. RESULTS: Our pooled analysis consisted of six RCTs. For 28-day mortality, no significant difference was found between the prolonged course and the short course. Administration of a short course of antibiotics increased the risk of recurrence of pneumonia in patients with VAP due to NF-GNB (RR 1.73; 95% CI: 1.17-2.54). Secondary outcomes, such as clinical resolution, duration of ICU stay, and duration of mechanical ventilation, revealed no significant difference between the two regimens. The quality of evidence was low for most outcomes. CONCLUSIONS: Low-quality evidence suggests that a short course of antibiotics is associated with a higher recurrence of pneumonia in NF-GNB VAP with no difference in mortality as compared to a prolonged course. For definitive conclusions, large-scale and blinded RCTs are required.

Emergency Physicians' Awareness of Medico-Legal Case Management: A Cross-Sectional Study from Saudi Arabia.

Background: Emergency department physicians often encounter medico-legal cases when patients initially present to the hospital, and thus there is a strong need for them to have robust medico-legal management and reporting knowledge. Objective: To assess the awareness of emergency department physicians of two major hospitals in the Eastern Province of Saudi Arabia in managing medico-legal cases. Methods: This descriptive cross-sectional survey-based study included all adult and pediatric emergency physicians working at King Fahd Hospital of the University and King Fahd Specialist Hospital, two major government hospitals in the Eastern Province of Saudi Arabia. The questionnaire included questions about demographic information, the workload in the emergency department, previous medico-legal training, and information about physicians' perspectives regarding medico-legal situations. Results: A total of 85 physicians completed the questionnaire, with most being Saudis (78.8%) and consultants (44.7%). Most participants (84.7%) immediately notified the police authority through the official procedure on suspicion of a case being criminal. However, only 28.2% of the participants were aware of how to complete the medico-legal report, and the majority (82.4%) had not received any specific training or attended specific courses in writing medico-legal reports. Most participants (91.8%) expressed the need for additional medico-legal case training programs, with continuous education (29.4%) being the preferred mode. In addition, 60% of the consultants were dissatisfied with the current medico-legal reporting and management workflow in their hospital. About half of the participants did not obtain photographs in medico-legal cases and did not know if their workplace provided a protocol for collecting evidentiary material such as clothes, swabs, bullets, remnants of foreign bodies, etc. Conclusions: The results of the present study indicate the necessity to consider periodical continuing medical education programs and workshops for emergency department physicians in the Eastern Province of Saudi Arabia to help them in appropriately handling medico-legal cases.

Effectiveness of endovascular repair versus open surgery for the treatment of thoracoabdominal aneurysm: A systematic review and meta analysis.

Background: Thoracoabdominal aortic aneurysms (TAAAs) are associated with significant comorbidities. The aim of our study is to compare the outcomes of open repair versus endovascular repair of TAAAs. Methods: A thorough literature search was conducted on MEDLINE, Embase, and Cochrane Central databases. The analysis included observational studies comparing the outcomes of surgical vs endovascular aneurysm repair (EVAR) of TAAA. Mortality, spinal cord ischemia (SCI), renal failure, stroke, paraplegia, and respiratory and cardiac problems were all included in the studies. The results were provided as relative risks (RRs) with 95% confidence intervals (CIs). These were then aggregated using an inverse variance weighted random-effects model, and the pooled analysis was displayed using forest plots. Results: This meta-analysis compromising of twelve studies revealed significant results, favoring endovascular repair versus open surgery for all-cause mortality (HR = 1.91; 95% CI: 1.68-2.18; P < 0.00001), SCI (HR = 1.62; 95% CI: 1.18-2.21; P = 0.003), respiratory complications (HR = 2.22; 95% CI: 1.78-2.77; P < 0.00001), and cardiac complications (HR = 1.66; 95% CI: 1.38-2.00; P < 0.00001). Upon subgroup analysis based on propensity matched, results were consistent and significant for the outcomes of all-cause mortality, cardiac complications, and respiratory complications. For the propensity unmatched subgroup, the incidence of all-cause mortality, SCI, respiratory complications, and cardiac complications were lower among endovascular repair cohort. Conclusion: Current evidence supports the use of endovascular repair over open surgery. However, there is a need to conduct dedicated randomized controlled trials to effectively compare and determine the benefits and risk of both strategies.
