Background: Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications. Methods:We randomised 2970 patients from 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were ≥45 years of age were eligible. Patients were randomly assigned to accelerated surgery (goal of surgery within 6 hours of diagnosis; 1487 patients) or standard care (1483 patients). The co-primary outcomes were 1.) mortality, and 2.) a composite of major complications (i.e., mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Outcome adjudicators were masked to treatment allocation, and patients were analysed according to the intention-to-treat principle; ClinicalTrials.gov, NCT02027896. Findings:The median time from hip fracture diagnosis to surgery was 6 hours (interquartile range [IQR] 4-9) in the accelerated-surgery group and 24 hours (IQR 10-42) in the standard-care group, p<0.0001. Death occurred in 140 patients (9%) assigned to accelerated surgery and 154 patients (10%) assigned to standard care; hazard ratio (HR) 0.91, 95% CI 0.72-1.14; absolute risk reduction (ARR) 1%, 95% CI -1-3%; p=0.40. The primary composite outcome occurred in 321 patients (22%) randomised to accelerated surgery and 331 patients (22%) randomised to standard care; HR 0.97, 95% CI 0.83-1.13; ARR 1%, 95% CI -2-3%; p=0.71.Interpretation: Among patients with a hip fracture, accelerated surgery did not significantly lower the risk of mortality or a composite of major complications compared to standard care.

BackgroundThe mobile medical unit/polyclinic (MMU/PC) was an essential part of the medical services to support ill or injured Olympic or Paralympics family during the 2010 Olympic and Paralympics winter games. The objective of this study was to survey the satisfaction of the clinical staff that completed the training programs prior to deployment to the MMU.MethodsMedical personnel who participated in at least one of the four training programs, including (1) week-end sessions; (2) web-based modules; (3) just-in-time training; and (4) daily simulation exercises were invited to participate in a web-based survey and comment on their level of satisfaction with training program.ResultsA total of 64 (out of 94 who were invited) physicians, nurses and respiratory therapists completed the survey. All participants reported favorably that the MMU/PC training positively impacted their knowledge, skills and team functions while deployed at the MMU/PC during the 2010 Olympic Games. However, components of the training program were valued differently depending on clinical job title, years of experience, and prior experience in large scale events. Respondents with little or no experience working in large scale events (45%) rated daily simulations as the most valuable component of the training program for strengthening competencies and knowledge in clinical skills for working in large scale events.ConclusionThe multi-phase MMU/PC training was found to be beneficial for preparing the medical team for the 2010 Winter Games. In particular this survey demonstrates the effectiveness of simulation training programs on teamwork competencies in ad hoc groups.

Background: Bacterial translocation (BT) from the gut can develop and persist after short periods of hemorrhagic shock secondary to traumatic injuries. Erythroopoietin (EPO) exerts hemodynamic and anti-inflammatory effects in addition to its erythropoietic effect. We tested the hypothesis that EPO given at the time of acute resuscitation with normal saline (NS), Ringer's lactate (RL) or 7.5% hypertonic saline (7.5%HTS) will limit shock-induced mucosal injury and BT. Methods: Rats were hemorrhaged 30 mL/kg over 10 minutes via arterial catheter for 50 minutes, then randomized to 1 of 6 resuscitation groups (n = 5/group): NS, NS+EPO, RL, RL+EPO, 7.5%HTS and 7.5%HTS+EPO. Intravenous EPO (1000 U/kg) was given at the start of NS or RL (3 times the volume of shed blood) and 4 mL/kg of 7.5%HTS+1 volume of RL resuscitation. Postresuscitation gut function was evaluated using agar cultures of mesenteric lymph nodes and portal vein plasma lipopolysaccharide, IL-6 and TNF-α levels. Three of 5 rats per group underwent light microscopic examination using semi-thin plastic sections of the distal ileum and fluorescein isothiocyanate dextran 4000 used to assess the distal ileum mucosal permeability to macromolecules. Results: Two hours postshock and resuscitation, BT to mesenteric lymph nodes decreased in the NS+EPO versus the NS group (299 ± 104 v. 1050 ± 105 CFU/gm, p < 0.05); the addition of EPO to the RL or 7.5%HTS had no effect. Comparing different solutions, there was a significant increase in BT in the NS group versus the RL+EPO, 7.5%HTS+EPO and 7.5%HTS groups (1050 ± 105 v. 357 ± 134, 462 ± 129, 428 ± 106 CFU/gm, respectively; p < 0.05). There were no significant differences in terminal ileum permeability between groups, but there was a noticeable trend in decreasing terminal ileum permeability in the EPO-treated groups: NS versus NS+EPO (18.0 ± 9.5 v. 12.9 ± 6.3 µg/mL, p = 0.84), RL versus RL+EPO (17.7 ± 5.9 v. 8.4 ± 2.7 µg/mL, p = 0.22) and 7.5%HTS versus 7.5%HTS+EPO (11.4 ± 6.4 v. 6.5 ± 2.9 µg/mL, p = 0.69). There was no significant morphological evidence of mucosal injuries and no cytokine differences between groups and within groups. Conclusion: Preliminary data from an uncontrolled mean arterial pressure hemorrhagic shock rat model revealed that BT is an early event occurring within 2 hours of injury and resuscitation before any evidence of histological injury. Erythroopoietin with NS significantly decreased BT to the portal vein as compared with NS alone, but not with RL and 7.5%HTS.Analgesia in the management of pediatric trauma in the resuscitative phase: the role of the trauma centre.
