Knowledge of the outcomes of critically ill patients is crucial for health and government officials who are planning how to address local outbreaks. The factors associated with outcomes of critically ill patients with coronavirus disease 2019 (Covid-19) who required treatment in an intensive care unit (ICU) are yet to be determined. Methods: This was a retrospective registry-based case series of patients with laboratory-confirmed SARS-CoV-2 who were referred for ICU admission and treated in the ICUs of the 13 participating centers in Israel between 5 March and 27 April 2020. Demographic and clinical data including clinical management were collected and subjected to a multivariable analysis; primary outcome was mortality. Results: This study included 156 patients (median age = 72 years (range = 22–97 years)); 69% (108 of 156) were male. Eighty-nine percent (139 of 156) of patients had at least one comorbidity. One hundred three patients (66%) required invasive mechanical ventilation. As of 8 May 2020, the median length of stay in the ICU was 10 days (range = 0–37 days). The overall mortality rate was 56%; a multivariable regression model revealed that increasing age (OR = 1.08 for each year of age, 95%CI = 1.03–1.13), the presence of sepsis (OR = 1.08 for each year of age, 95%CI = 1.03–1.13), and a shorter ICU stay(OR = 0.90 for each day, 95% CI = 0.84–0.96) were independent prognostic factors. Conclusions: In our case series, we found lower mortality rates than those in exhausted health systems. The results of our multivariable model suggest that further evaluation is needed of antiviral and antibacterial agents in the treatment of sepsis and secondary infection.
BACKGROUND:The current study explores the trends in the application of combat casualty care following the publication of clinical practice guidelines (CPGs) in five domains for 13 years. METHODS:The Israel Defense Forces Trauma Registry was used to assess practice and adherence to guidelines in five domains: (a) crystalloid transfusions, (b) tranexamic acid use, (c) freeze-dried plasma use, (d ) chest decompression, and (e) airway management. All patients injured between January 2006 and December 2018 were included in the analysis. Trends were analyzed and presented monthly using linear regression and were compared using the Chow test. RESULTS: The mean ± SD crystalloid volume transfused decreased from 1,179 ± 653 mL in 2006 to 466 ± 202 mL in 2018 (B = 0.016, 0.006-0.044). The proportion of patients with an indication treated with tranexamic acid dropped from 8% (238 of 2,979 patients) to 2.5% (60 of 2,356 patients) following the stricter guideline's publication. Freeze-dried plasma administration in indicated casualties rose from 12.5% in 2013 to 48% in 2018 (B = 1.63, 1.3-2.05). The overall proportion of casualties undergoing chest decompression rose from 1% (61 of 6,036 casualties) to 1.5% (155 of 10,493 casualties) following the release of a new CPG in 2012 (p = 0.013). There were no significant trends in intubation ratios before (B = 0.987, 0.953-1.02) or after 2012 (B = 10.2, 0.996-1.05). CONCLUSION:Some aspects demonstrate the desired trends in response to new CPGs; in others, initial improvement is achieved but followed by stagnation. In some medical care aspects, completely unexpected and undesirable trends are observed. Every change and update in CPGs should be based on reliable data. The effect of every change must be monitored carefully to ensure adequate adherence to lifesaving guidelines.
Background The anterior aspect of the auricle is a complex 3-dimensional structure. Each anatomical component in this region has an essential role in the aesthetic appearance of the ear and face. The reconstruction of defects in this region is challenging because of the lack of mobile, excess skin for primary closure, and the inability to skin graft overexposed cartilage. Objective The aim of the study was to present the planning and surgical technique of a simple, reproducible, 1-stage flap, for the reconstruction of the anterior aspect of the auricle. Patients and Methods A series of 11 patients, who underwent reconstruction of the anterior aspect of the auricle with 1-stage, inferiorly based, preauricular, cutaneous flap. All reconstructions were conducted under local anesthesia, and the defects were mainly due to tumor resections or skin necrosis after otoplasty. The average defect size was 1.5 cm. The flap was applied to different sites of the anterior auricle. Results All flaps survived except one, where there was partial flap loss. The aesthetic results were excellent, with no auricular deformity. Conclusions The inferiorly based, preauricular flap is a versatile flap for a safe, simple, and reproducible, 1-stage reconstruction for almost every region of anterior ear defect, with excellent aesthetic results.
Background Several tools have been proven to predict the need for massive transfusion in trauma casualties, yet tools that are easily applicable in the prehospital setting for predicting the need for any blood product transfusion in the emergency department (ED) are lacking. Methods A retrospective analysis of the cross‐referenced Israeli Defense Forces Trauma Registry and the Israeli National Trauma Registry databases was performed to identify predictors for any blood product transfusion in the ED. A scoring system was developed after internally validating the prediction model. Division to risk groups was performed. Results Seven variables (systolic blood pressure, heart rate, arterial oxygen saturation, trunk involvement, mechanism of injury, chest decompression, and tourniquet application) were included in the scoring system, ranging from 0 to 11.5. Risk groups for ED transfusion included very low (0.8%), low (3.2%), intermediate (8.5%), and high (31.2%) risk. Conclusion A scoring system for predicting the need for any blood product transfusion in the ED was developed, based on information readily available in the early stages of prehospital resuscitation, allowing the receiving medical facility to prepare for that need.
BACKGROUND The American College of Surgeons and the National Association of Emergency Medical Technicians advise securing a definitive airway if there is any doubt about the trauma patient's ability to maintain airway integrity. The objective of this study was to investigate the association between a success in securing a definitive airway in the prehospital setting and survival among trauma patients, in which the provider deemed a definitive airway was necessary. METHODS The study included all trauma patients recorded in the Israel Defense Forces Trauma Registry between the years 2006 and 2018 for whom a prehospital attempt of securing a definitive airway was documented. The successful definitive airway group was defined by explicit documentation of success in either endotracheal intubation or cricothyrotomy. Logistic regression was performed to determine the association between success in securing a definitive airway and survival. RESULTS A total of 566 (3.6%) trauma patients underwent attempts to secure a definitive airway (successful in 425 patients and unsuccessful in 141). Prehospital survival rates were similar (77.6% vs. 78.0%, p = 0.928) between the groups. Whether the definitive airway was successful did not affect the rates of prehospital survival, neither before (odds ratio, 0.98; 95% confidence interval, 0.61–1.54) nor after adjustment for the other factors (odds ratio, 0.91; 95% confidence interval, 0.55–1.46). CONCLUSION This study was unable to find an association between a successful definitive airway in the prehospital setting and survival, even after adjustment for injury characteristics and in multiple models. Furthermore, survival rates were high among trauma patients in which the provider deemed a definitive airway as necessary yet failed in securing one. These results suggest that the liberal use of these invasive airway procedures in the prehospital setting should be reconsidered. LEVEL OF EVIDENCE Retrospective study, lebel III.
BackgroundThe combat role of the twenty-first century infantry soldier has changed and accordingly their boots should evolve to meet these new needs and maximize soldier performance.ObjectiveTo evaluate injuries and durability of the hot weather infantry boots (HWIB) in elite infantry training and assess the initial performance of newly designed Israeli infantry boots (NDIB).MethodsIn Phase 1, the durability of the HWIB during elite infantry training was evaluated at weeks 10, 19 and 64 in a cohort of 67 recruits. At each exam recruits removed their boots which were assessed for wear and integrity and photographed. The number of times recruits changed their boots was recorded. In Phase 2, foot injuries were assessed in a cohort of 73 elite infantry recruits wearing HWIB. In Phase 3, 65 infantry recruits were issued the NDIB. Recruits feet were measured for width and shoe size using the Brannock device and then followed for problems associated with their boots. Foot lesions were document by photographs.ResultsPhase 1: The mean longevity of HWIB in training was 5.2 ± 0.2 (SE) months, (95 % CI 4.83–5.61). Phase 2: 38 % of the elite infantry recruits wearing HWIB had at least one complaint and 31 (42 %) were found to have boot related injuries in a total of 56 injured areas. Phase 3: The mean predicted boot size (42.8 ± 1.7) based on Brannock measurements, was less than the size of the NDIB actually worn, 43.1 ± 1.6. Only 34.8 % of the feet were width D (the standard shoe width). At 9 day follow up, 55 of the 65 recruits who wore NDIB reported at least one problem with them (85 %, p < 0.0001, compared to HWIB). By 3 weeks, all but five recruits had returned to wearing the HWIB. Of the recruits wearing NDIB, 47 (72 %) were found to have had at least one boot related injury with a total number of 180 injured foot areas (p = 0.0004, compared to HWIB).ConclusionsThe HWIB was well tolerated by the elite infantry recruits and associated with significantly less foot injuries than the NDIB. The longevity of the HWIB in demanding elite infantry training was five months. Trial registration: NCT02810002 retrospectively registered June 22, 2016
