Objective To estimate the potential influence of pre-operative patient condition on the benefit of earlier hip fracture surgery for elderly patients. Background Many studies emphasize the benefit of earlier hip fracture surgery for patient survival. However less is known regarding how this relationship is influenced by clinical factors which could serve as potential contra-indicators for earlier surgery. Rushed surgery of patients with contra-indications may even compromise their survival. Methods A retrospective study of patients aged 65 and above with an isolated hip fracture following trauma, based on data from 19 hospitals of the national trauma registry available for the years 2015–2016. Registry data was crossed with data on co-morbidities and medication intake from the biggest health insurance agency in the country, serving more than 50% of the country's population. Mediation analysis was performed on a wide list of co-morbidities, medications and clinical test results in order to establish the mediation of their relationship with inhospital mortality by earlier hip fracture surgery. Factors found significant in the mediation analysis were utilized to adjust a logistic regression for predicting inhospital mortality by function of waiting time to surgery and patient's sex and age. Results Anti-coagulant and anti-platelet intake; test results pointing to decreased kidney function and being diagnosed with diabetes or Ischemic Heart Disease were found to be significantly mediated in their influence on inhospital mortality by hip fracture surgery. Despite anti-platelet intake and kidney function having a significant impact on mortality in the multi-variate analysis, the positive effect of earlier hip surgery on survival remained unchanged after adjustment. Conclusions Earlier hip fracture surgery was found to be beneficial for elderly patients even when their co-morbidities and medication intake are taken into account.

Neck injuries are an important cause of combat mortality and morbidity. This study's objective was to examine the characteristics and causes of neck injuries among Israel Defense Forces (IDF) and emphasize the best treatment protocols for the advanced life support providers in the prehospital combat environment.The IDF Trauma Registry (IDF-TR) includes prehospital data regarding casualties treated by the IDF's medical forces. This study was a retrospective, observational study that included all casualties who were injured between January 2006 and December 2018.Between January 2016 and December 2018, 3294 casualties were recorded. During the study period, 1% (41/3,394) of all injury casualties in the registry were isolated neck injuries compared to 94% (3185/3,394) without neck injury. 42% (14/41) percent of the neck casualties were classified as urgent compared to 26% (830/3185, P = 0.09) in the no neck group. The most frequent type of injury mechanism in the neck casualties was penetrating injury (54% 22/41), mostly due to shrapnel (68% 15/22). 60% of neck injured personnel were injured during the 2nd Lebanon War and Operation Protective Edge in high-intensity conflicts. As for life-saving interventions, advanced airway interventions were performed in 12% of neck injured group (5/41) compared to 3% (104/3185, P = 0.02) in the no neck group. We revealed that cricothyroidotomy was performed in almost 10% (4/41) of neck injured casualties compared to only 1% (19/3185, P0.0001) in no neck casualties. As for damage control resuscitation, neck injury casualties received higher amounts of Fresh Dried Plasma 7% (3/41) Vs. 1% (32/3185, P = 0.02) and Tranexamic acid 15% (6/41) Vs. 4% (124/3185, P = 0.01) compared to non-neck casualties.Military neck injuries are a significant cause of substantial disability and result in incompatibility with combat duties in previously healthy soldiers. Prompt medical care, especially urgent hemodynamic and airway management, is paramount in these injuries. Routine use of designated neck protection might lower the number of neck injuries, mitigate their severity, and even decrease mortality.Level III (Retrospective study with up to two negative criteria).

Early application of tourniquets has reduced injury death rates. At the end of 2013, the Israel Defense Forces Medical Corps completed a military-wide introduction of the Combat Application Tourniquet as the standard-issued tourniquet. The accompanying clinical practice guideline encouraged combat soldiers and medical teams towards a liberal use of tourniquets for extremity injuries, even when in doubt.This study aimed to assess the effects of the wide introduction of advanced tourniquets on the rate of tourniquet applications, the type of tourniquet applied, and the differences in hospitalisation outcomes following the introduction.The study population was composed of hospitalised military casualties with an extremity injury treated by military medical teams between 2006 and 2015. Prehospital data were extracted from the Israel Defense Forces Trauma Registry and matched to corresponding hospital data from the Israeli National Trauma Registry. Two periods were compared: 2006-2013 "pre-intervention period" and 2014-2015 "post-intervention period".A total of 1,578 casualties were recorded during the study period. Of these, 320 (20.3%) occurred between 2014-2015. Characteristics of casualties in the post-intervention period were similar to those in the pre-intervention period including the rate of traumatic amputations (2.5% vs 2.2%, p = 0.93) and Injury Severity Score of 16 or above (12.8% vs 14.9%, p = 0.40). The rate of tourniquet application was more than four-fold in the post-intervention period compared to the pre-intervention period (22.8% vs 5.5%, p 0.001). Nevertheless, rates of in-hospital amputations (1.6% vs 1.6%, p = 1.00) and death (0.9% vs 1.3%, p = 0.53) were similar in the two periods.Following the IDF military-wide introduction of advanced tourniquets, the tourniquet application rate rose sharply, the use of old tourniquets ceased over time, and in-hospital amputation rate did not increase. These findings suggest that the awareness for haemorrhage control using advanced tourniquets rose.

Work absenteeism following an injury creates an economic burden on society and the individual. Programs encouraging return to work (RTW) should be implemented for high risk populations. The aim of this study was to identify the predictors for duration until RTW following an injury. The Israeli National Trauma Registry and the National Insurance Institute database (2008-2013) were linked. Logistic-regression models tested the probability not RTW within 1 month, 1 year and 2 years among 67% of the population and the quality of the model was examined among 33% of the population. The study population comprised 45,291 casualties (aged 21-67 and employed prior to injury as salaried workers). The majority of the study population (61%) RTW within 1 month from the injury event. Injury severity, multiple injuries, brain injury, traffic related injuries and fall injuries were significantly associated with work absenteeism. A dose-response relationship was found between income and not RTW: the lower the income the greater was the chance of not RTW. Among casualties with occupational injuries the odds for not RTW within a month, a year and 2 years were respectively, 3.7, 2.4 and 2 times significantly greater in comparison with casualties not injured at work. Underprivileged ethnic groups (Arabs and immigrants from Ethiopia) had a greater chance for long out of work stay following an injury. The outcomes of this study identified casualties at high risk for not RTW and enables health professionals to develop intervention programs focusing on returning to a productive lifestyle.

Introduction Bus public transportation is preferred for its perceived safety. Data from several countries, however, alarm of non-collision injuries associated with bus use. The aim of the current study was to estimate the prevalence of non-collision bus injuries, and compare and identify population group at high risk for severe injuries, to serve as a basis for policy makers. Methods A retrospective analysis of the Israeli National Trauma Registry cohort for the years 2015–2017 was carried out. Database consists of 20 hospitals nationwide. Casualties hospitalized following a non-collision injury on a bus were identified. Demographic, injury characteristics, and hospital resources utilization were compared according to the place of injury; inside the bus or during boarding or alighting. Results During follow up, 704 hospitalized non-collision related bus casualties were recorded. Most of the casualties (75%) fell inside the bus and 25% during boarding or alighting. The majority (67%) of hospitalized patients were 60 years old or above, mostly injured while boarding or alighting the bus, and 72% were women. Frequent injured body regions were lower extremities, head and torso. Passengers injured inside bus sustained more chest injuries, but less lower extremities injuries, compared to those boarding or alighting the bus. More hospital resources were required to treat passengers injured while boarding or alighting the bus. Conclusions This systematic registry-based analysis of non-collision bus injuries confirms the greater risk of being injured while using bus transportation among women and older passengers. Primary attention for prevention policies should be given to injuries occurring during boarding or alighting of the bus. Additional policy recommendations are discussed.

BACKGROUND: Covid-19 has brought healthcare workers in general and nurses in particular into the limelight as never before. It is important to study the intensity of the impact of this pandemic on the profession. OBJECTIVE: This study aims to assess the occupational satisfaction during the pandemic of Covid-19 among the nurses in Israel, to shed light on conditions of work and to identify factors associated with low occupational satisfaction. METHODS: Cross-sectional study of 130 Israeli nurses. Minnesota Satisfaction and Measure of Job Satisfaction questionnaire with 28 items was used to assess occupational satisfaction. RESULTS: In the multivariable model, nurses working in the community had higher occupational satisfaction than those working in hospitals (s = 0.24, p = .032); nurses who took care of patients who tested positive for Covid-19 had significantly lower occupational satisfaction than others (s = -0.48, p = .009). Most of the sample reported lack of personal protective equipment (PPE). Nurses who experienced lack of PPE reported lower occupational satisfaction than those who did not (3.4 vs. 3.8, p = .039). Occupational satisfaction was mainly based on the component, built by the intrinsic characteristics of the occupation related to the personal accomplishment. Most of nurses had to increase their workload as a result of staff shortages, but the elevation of the workload was not associated with lower occupational satisfaction. CONCLUSION: Even under the circumstances of the pandemic, the most important nurses` occupational values are worthwhile accomplishments, importance of professional challenge, diversity and interest in the job, personal growth and development and independence in their practice.

BackgroundEthnic disparities have been associated with injury and mortality. The impact of ethnicity on head and neck injury (HNI), traumatic brain injury (TBI), in-hospital mortality and resource utilization following a motorcycle crash (MCC) is undetermined. This study explored the influence of ethnicity in these aspects and the effect of helmet use on HNI and TBI following a MCC.MethodsThe National Trauma Registry provided hospitalization data on motorcycle riders and passengers between 2008 and 2017. Ethnicity was classified as Jews or Arabs, the two major ethnic groups in Israel. Univariate followed by multivariable logistic models were applied to examine ethnic disparities. Mediation effect was tested by structural equation modeling.ResultsAmong 6073 MCC casualties, Arabs had increased odds of HNI (OR = 1.37,95% CI = 1.12–1.65) and TBI (OR = 1.51,95%CI = 1.12–1.99), and a six-fold decreased odds of helmet use (OR = 0.16,95%CI = 0.12–0.22). The HNI and TBI associations with ethnicity were mediated by helmet use. Arabs had significantly higher odds for admission to intensive care unit (OR = 1.36,95%CI = 1.00–1.83), and lower odds for ambulance evacuation (OR = 0.73,95%CI = 0.61–0.89) and discharge to rehabilitation (OR = 0.55,95%CI = 0.39–0.7). In-hospital mortality was not associated with ethnicity.ConclusionsHelmet non-use is an important etiologic factor associated with motorcycle-related HNI and TBI among Arabs. While in Israel, ethnic equality exists in in-hospital health care, disparities in ambulance and rehabilitation utilization was found. Intervention programs should target the Arab population and focus on helmet compliance.

Background Road traffic collisions (RTC) are known to be one of the major causes of maxillofacial trauma (MFT). The road user factor is of crucial importance in the prevalence, severity and treatment of the maxillofacial injuries. The aim of the study was to determine the prevalence of maxillofacial trauma among road users as well as to illustrate injury patterns and identify road users at high risk. Methods This historical prospective multi-center study was based on Israel's Trauma Registry between 2008-2018, which included 4,829 hospitalized patients following RTC with MFT. Data were analyzed according to six road user types (vehicle driver, passenger, bicyclist, motorcyclist, pedestrian and e-bike/scooter), maxillofacial injury location and maxillofacial treatment. Results MFT, which accounts for 5% of the hospitalized RTC injuries, was not equally distributed among road users, as bicyclists and e-bike/scooters were more prone to maxillofacial trauma (7.2% and 10.1%, respectively) than vehicle drivers (3.2%). Children (age 0-14 years) comprised almost half of the cyclists, 25% of the pedestrians and 20% of the passengers. Some MFT patients experienced multiple injuries, with the majority involving jaw and facial bones and to a lesser extent the mouth, teeth, gingiva and alveolar bone (mouth and dento-alveolar (DA) trauma). Approximately 30% of hospitalized road casualties with MFT underwent MF surgery, with the need for surgery lowest among pedestrians. Conclusion Hospitalized road casualties had different types of MFT in terms of prevalence, location, severity and treatment, depending on the road user type. Appropriate preventive measures and the proper use of restraints are recommended to reduce maxillofacial injuries.

BACKGROUND This prospective study evaluated the effect of routine, uncontrolled, Israeli field storage conditions on the safety and efficacy of Lyo-Plas N Freeze-Dried Plasma (FDP) at the end of the manufacturer's shelf life, and up to 24 months post expiry. Clotting factors V, VIII and XI, proteins S, C, fibrinogen, PTT, ATIII, VWF, and INR as well as TEG, DDM, residual moisture, pH, and sterility of FDP returned from field units after uncontrolled storage were evaluated. STUDY DESIGN AND METHODS Parameters measured at the end of manufacturer shelf life, as well as 6, 12, 18, and 24 months after expiry, were compared to those of freshly supplied FDP doses. RESULTS Changes were found when comparing freshly supplied FDP to all field-stored groups in INR, PT, PTT, pH, fibrinogen, and factor VIII. A significant change was also seen in Factor XI in the 12, 18, and 24 months post-expiry samples, Factor V and R in the 24 months post-expiry samples, MA in the 12, 24 months post-expiry group, and Protein C in the 18 months post-expiry group. An increase in the residual moisture from 0.90% in freshly supplied FDP to 1.35% in 24 months post-expiry FDP.; all p

Background Traumatic injury is one of the main reasons for temporary and permanent occupational disability. The objective of this study was to define the role of socio-economic position on post-injury occupational absenteeism. Methods This was a nationwide retrospective cohort study, based on linking The Israeli National Trauma Registry (INTR) and the National Insurance Institute (NII) databases. The study population included 44,740 injured workers (residents of Israel, aged 21–67, hospitalized between 2008 and 2013 and employed prior to injury as salaried workers). Logistic-regression models tested the probability of not returning to work (RTW). Results The majority of the study population (61%) RTW within 1 month following the injury event. Income prior to injury was significantly associated with longer out of work stay, explaining 9% variance. A significant interaction (p value

Background Road traffic accidents (RTA) are not equally distributed between ethnic groups, disproportionately affecting minorities. In Israel, Arabs are at higher risk of involvement in RTA relative to their proportion in the population. This study aims to compare the risk of in-hospital mortality from RTA between Arabs and Jews in Israel and to identify the factors associated with mortality in each population group. Methods This study is based on the Israeli National Trauma Registry of patients hospitalized due to road traffic injuries (Injury Severity Score 16+) between 2008 and 2017. Demographic, injury and hospitalization characteristics, evacuation means and in-hospital mortality were analyzed. Hierarchical multivariate logistic regression with random intercept for the treating hospital was performed to estimate the risk of mortality. Results Of the 11,523 hospitalizations reported, 29% were Arabs, which is higher than their proportion in the Israeli population (21%). When comparing Arabs with Jews they were younger (ages 0–24 years - 61% vs 30%), injured as a car driver (28% vs 20%) or passenger (21% vs 15%) and less likely to be a motor cyclist (8.8% vs. 19.2%). In addition, Arabs were more likely to suffer from critical injuries (51% vs 44%) and head injuries (71% vs 66%). Although Arabs were less likely to be evacuated by ambulance (68% vs 80%), they were more likely to be evacuated by a private vehicle or an emergency medical helicopter. Transfers between hospitals were greater among Arabs (14% vs 22%), as were hospital admissions “outside official work hours” (70% vs 78%) and hospital resource utilization. After accounting for demographic, injury, and hospitalization characteristics the risk of in-hospital mortality was significantly higher among Arabs compared to Jews (OR: 1.63, 95% CI: 1.14–2.32). The significantly higher mortality among Arabs was apparent in the sub-group of patients who were critically injured and in those who arrived at the hospital “outside official work hours”. Conclusions This study suggests the need for developing appropriate interventions focusing on the Arab community in general, and according to the analysis of risk groups and areas of injury in particular, including rapid access to emergency medical services and definitive care.

Background Despite relatively high rates of Postpartum Depression (PPD), little is known about the granting of social security benefits to women who are disabled as a result of PPD or of other postpartum mood and anxiety disorders (PMAD). This study aims to identify populations at risk for underutilization of social security benefits due to PMAD among Israeli women, with a focus on ethnic minorities. Methods This retrospective cohort study is based on the National Insurance Institute (NII) database. The study population included a simple 10% random sample of 79,391 female Israeli citizens who gave birth during 2008–2016 (these women delivered a total of 143,871 infants during the study period), and who had not been eligible for NII mental health disability benefits before 2008. The dependent variable was receipt of Benefit Entitlement (BE) due to mental illness within 2 years following childbirth. Maternal age at delivery, population group, Socio-Economic Status (SES), family status, employment status of the mother and her spouse, and infant mortality were the independent variables. Left truncation COX proportional hazard model with time-dependent variables was used, and birth number served as a time discrete variable. Results Bedouin and Arab women had significantly lower likelihood of BE (2.6 times lower and twice lower) compared with other ethnic groups (HR = 0.38; 95% CI: 0.26–0.56; HR = 0.47; 95% CI: 0.37–0.60 respectively). The probability of divorced or widowed women for BE was significantly higher compared to those living with a spouse (HR = 3.64; 95% CI: 2.49–5.33). Lack of employment was associated with higher likelihood of BE (HR = 1.54; 95% CI: 1.30–1.82). Income had a dose-response relationship with BE in multivariable analysis: lower income was associated with the nearly four-fold greater probability compared to the highest income quartile (HR = 3.83; 95% CI: 2.89–5.07). Conclusions Despite the exceptionally high prevalence of PMAD among ethnic minorities, Bedouins and Arabs had lowest likelihood of Benefit Entitlement. In addition to developing programs for early identification of postpartum emotional disorders among unprivileged ethnic groups, awareness regarding entitlement to a mental health disability allowance among ethnic minorities should be improved.

Objective To evaluate and compare, at the national level, injury trends and, characteristics and to identify high risk groups of electric bike (E-bike) and mechanical bicycle (M-bike) related hospitalizations as a key message for public policy. Methods Historic prospective study based on data from the Israel National Trauma Registry (INTR), between 1.1.2013 and 31.12.2017. All hospitalized casualties were E-bikers and M-bikers. Results During the study period, 1733 E-bikers and 7259 M-bikers were hospitalized. Arab children (age 0–15) and young adults (age 16–29) were at higher risk for E-bike and M-bike casualties respectively. The hospitalization rate per 1000 vehicles was lower for E-bikers in comparison to M-biker. However, during the five year period a dramatic increase in E-bike related hospitalizations was reported coinciding with a decrease of M-bike related casualties. Among M-bikers, the decrease in hospitalization rate was for accidents on both inter and intra-city roads, but not on unpaved roads, which remained stationary, suggesting that the transportation mode is changing. In comparison to the M-bikers, E-bikers were at greater risk for enduring head injuries (OR 1.16 95% CI 1.00–1.25) and lower extremity injuries (OR 1.37 95% CI 1.23–1.52), to undergone surgery (OR 1.13 95% CI 1.00–1.26), having longer hospital stays (OR 1.44 95% CI 1.23–1.68) and being discharged to rehabilitation center (OR 1.43 95% CI 1.09–1.86). Conclusion During the last five years in Israel there is a dramatic increase in E-bike related hospitalized casualties corresponding to a substantial increase in E-bike usage. In comparison to M-bikers, there is a lower casualty rate but these casualties are more severely injured and utilize more hospital resources. It is of utmost importance to identify these high risk groups in an effort to develop culturally appropriate interventions for these road users, including training, awareness and helmet enforcement. Policy change recommendations are discussed.

To examine the relationship between neighborhood socioeconomic level (NSEL) and injury-related hospitalization. The National Trauma Registry (INTR) and the National Population Census (NPC), including NSEL, were linked by individual identity number. Age-adjusted logistic regression predicted injury hospitalization. Mantel–Haenszel X2 was used for linear trends. NSEL was divided into 20 clusters. The population comprised 7,412,592 residents, of which 125,829 (1.7%) were hospitalized due to injury. The injury hospitalization rate was at least 42 per 10,000 per year. Except for the very low SEL, an inverse relationship between NSEL and all-cause injury was found: 46.1/10,000 in cluster 3 compared to 22.9/10,000 in cluster 20. Hip fracture-related hospitalizations among ages 65 + decreased as SEL increased (2.19% o in cluster 2 compared to 0.95% in cluster 19). In comparison with Jews, non-Jews were 1.5 times more likely to have an injury-related hospitalization [OR 1.5 (95% CI 1.50–1.55)]. The INTR and the NPC were successfully linked providing individual and injury hospitalization data. The outcomes confirm the strong relationship between injury mechanism and NSEL.

Hemorrhage is the leading cause of possible preventable death in the battlefield. There is an increasing evidence for the effectiveness of blood component therapy in general, and plasma infusion in particular but their use is less applicable in the prehospital setting due to logistic difficulties. Israeli Defense Force has implemented the use of freeze-dried plasma (FDP) at the point of injury (POI), this adoption of FDP use entailed doubts regarding the feasibility and effectiveness of this practice. In this article, we present our experience with the use of FDP at the POI and prehospital setting regarding the feasibility, safety, adverse reactions, and adherence to clinical practice guidelines.This is a descriptive retrospective cohort study based on all casualties receiving FDP during January 2013 to June 2016. The study describes the injury, treatment, and outcome characteristics from POI until hospital discharge.During the study period, 109 casualties received FDP. The majority were men, aged 18 years to 35 years. Multiple severe injuries were found in almost half of the casualties, 78% had penetrating injury, and more than half were involved in a multicasualty event. Eighty-three percent were treated with one unit of FDP, 13% with two units, and 4% casualties with three units, nine patients (8.2%) were also treated in the prehospital setting with packed red blood cells. Fifty-seven percent fulfilled at least one criterion for the administration of FDP. Lifesaving interventions were required in 64%. In five (4.6%) cases, there were difficulties with FDP administration. Side effects were reported in one female patient.This study supports the usage feasibility of FDP at the POI and in the prehospital setting. Further adjustment of the clinical practice guidelines is required basing it not only on pathophysiologic parameters but also on clinical judgment. Further investigation of the available data is required to learn about the effectiveness of FDP at POI.Retrospective case series study, level IV.

The objective of this study was to describe demographic and injury characteristics of hospitalized injured patients involved in e-bike and motorized scooter accidents at a national level in Israel divided by different road user groups: riders and pedestrians.This was a retrospective study based on data from the National Trauma Registry, between January 1, 2013, and December 31, 2015. All hospitalized casualties due to the involvement of an e-bike or motorized scooter were included. The type of hospitalized road user was further categorized and described by different variables.During the study period, the Israel Trauma Registry identified 795 hospitalized patients due to an e-bike or motorized scooter accident, with a dramatic 6-fold increase from 2013 to 2015. Although the majority of the injured patients were riders, 8% were pedestrians. Among the total casualties, 33% were children aged 0-14 years and among pedestrians 42% were children and 33% were seniors (ages 60+). Five persons died in hospital, 3 riders and 2 pedestrians.E-bike and motorized scooter riders represent the majority of patients hospitalized due to related traffic incident. This finding questions the social and economic advantages of electric-powered 2-wheeled vehicles.

Patients with extensive burn injuries suffer from multisystem trauma, which affects their medical, psychological, and social well-being for many years. Monitoring those patients has revealed changes in the endocrine, cardiac, and respiratory systems years after the injury. Our study tries to examine whether changes manifest as a higher risk of death during their lifespan, compared with the general population. Data from the years 1998 to 2013 regarding two groups of patients was obtained from a national trauma registry: one group had suffered burns over 20% of their TBSA and survived the hospitalization period and the second group was a control group of patients admitted with minimal trauma (Injury Severity Score = 1-minor injury to a single body region). Mortality rates during the posthospitalization period were compared after adjusting for age and follow-up periods. The authors collected 1115 second- or third-degree burn victims with 20% TBSA and 81,688 trauma victims with an Injury Severity Score = 1. Follow-up periods ranged from 8 months to almost 17 years. When comparing the groups after correcting for age, sex, and follow-up period, no significant differences in mortality risk were found. Possible explanations for the lack of differences in mortality risk include the lack of an adequate follow-up period, a misguided research hypothesis (ie, despite existence of physiological changes in burn patients, these changes do not affect the lifespan), or a control group that does not optimally represent mortality in the general population.

BackgroundThe use of off-road vehicles such as all-terrain vehicles (ATVs) and recreational off-highway vehicles has increased in recent years. A higher percentage of patients hospitalised following ATV crashes suffered severe injuries, compared with those hospitalised following other MVCs.ObjectiveTo identify incidence of ATV-related injury and characterise groups with higher prevalence.MethodsA retrospective study of the Israel National Trauma Registry data between years 2008 and 2016. ATV crash victims were compared with other types of MVC casualties according to demographics, injuries and hospital resource utilisation. Identifying groups with greater prevalence for severe injuries caused by ATV crashes was conducted using logistic regressions.ResultsAn increase of 49% in the number of casualties hospitalised following an ATV crash was observed between 2013 and 2016. Non-Jews, males and users 15–29 years old were hospitalised at a higher rate compared with their proportion in the population. ATV crash casualties were more severely injured compared with other MVC casualties (22% vs 14%), had longer hospital length of stay (8+ days) (25% vs 18%), more admissions to intensive care units (16% vs 10%) and underwent more surgery (39% vs 26%, respectively). Males, non-Jews and casualties who did not wear a helmet were about two times more likely to suffer from severe head injury (95% CI 1.20 to 3.60, 1.41 to 2.75 and 1.27 to 4.73, respectively).ConclusionsAn increase in ATV-related casualties was observed. A customised safety intervention programme is needed that targets demographic groups identified with higher injury incidence. Awareness of legislated and common sense ATV safety practices, specifically helmet use, should be raised.

Background Populations of different ethnicity and country of origin living in the same country may possess particular features of violence-related injuries. This study aims to compare violence-related injury characteristics and circumstances, hospital resource utilization and in-hospital mortality among the major ethnic groups in Israel. Methods A study based on the Israeli National Trauma Registry database of patients hospitalized due to violence-related injuries between 2008 and 2017. Data included demographic, injury and hospitalization characteristics and in-hospital mortality. Statistical analysis included χ 2-test and multiple logistic regression. Results During the study period, 16,151 violence related-hospitalizations were reported, of which; 46.1% were Arab Israelis (AI), 3.2% were Israelis born in Ethiopia (IBE), 12.7% were Israelis born in the former Soviet Union (IBFSU) and 38.0% were all other Israelis (AOI). The proportion of violence-related hospitalizations among AI, IBE and IBFSU was greater than their respective proportion in the Israeli population. In comparison to the other groups, stab injuries were significantly greater among IBE (30% vs 39%); unarmed brawl-related injuries were greater among IBFSU (22–41% vs 49%) and firearm injuries were greatest among AI (2–8% vs 23%). These differences in violence mechanism persisted even after accounting for age, gender, injury place and time differences. The foreign born groups had higher rates for injuries sustained on the street/road (58% for IBE, 54% for IBFSU vs 46% for AI and AOI, each), with IBE also showing higher rates for weekend and weeknight injuries compared to the other groups (83% vs 71–75%). IBE were more likely to suffer from severe and critical injuries (19% vs 12–16%), to be admitted to the intensive care unit (17% vs 9–11%) and to have prolonged hospital stays of seven days or more (20% vs 16–17%), with no significant difference in in-hospital mortality between the comparison groups. Conclusions Characteristics of violence-related casualties differed significantly among diverse ethnic populations living in the same country. Each population group showed specific attributes regarding injury mechanism, circumstances, severity and hospital utilization. Violence prevention programs should be culturally adapted and take into account ethnicity and country of origin of the target population.

TBI may be defined by different methods. Some may be most useful for immediate clinical purposes, however less optimal for epidemiologic research. Other methods, such as the Abbreviated Injury Score (AIS), may prove more beneficial for this task, if the cut-off-points for their categories are defined correctly.To reveal the optimal cut-off-points for AIS in definition of severity of TBI in order to ensure uniformity between future studies of TBI.Mortality of patients with TBI AIS 3, 4 was 1.9% and 2.9% respectively, comparing with 31.1% among TBI AIS 5+. Predictive discrimination ability of the model with cut-off-points of 5+ for TBI AIS (in comparison with other cut-off-points) was better. Patients with missing Glasgow Coma Scale (GCS) in the ED had an in-hospital mortality rate of 11.5%. In this group, 25% had critical TBI according to AIS. Normal GCS didn't indicate an absence of head injury, as, among patients with GCS 15 in the ED, 26% had serious/critical TBI injury. Moreover, 7% of patients with multiple injury and GCS 3-8 had another reason than head injury for unconsciousness.This study recommends the adoption of an AIS cut-off ≥ 5 as a valid definition of severe TBI in epidemiological studies, while AIS 3-4 may be defined as 'moderate' TBI and AIS 1-2 as 'mild'.

To examine whether characteristics and circumstances of injuries are related to ethnicity.The study was based on the Israeli National Trauma Registry data for patients hospitalized between 2008 and 2011. Data included demographics, injury, hospital resource utilization characteristics and outcome at discharge. Univariate analysis followed by logistic regression models were undertaken to examine the relationship between injury and ethnicity.The study included 116,946 subjects; 1% were Ethiopian Born Israelis (EBI), 11% Israelis born in the Former Soviet Union (FSUBI) and 88% the remaining Israelis (RI). EBI were injured more on street or at work place and had higher rates of penetrating and severe injuries. However, FSUBI were mostly injured at home, and had higher rates of fall injuries and hip fracture. Adjusted analysis showed that EBI and FSUBI were more likely to be hospitalized because of violence-related injuries compared with RI but less likely because of road traffic injuries. Undergoing surgery and referral for rehabilitation were greater among FSUBI, while admission to intensive care unit was greater among EBI.Targeted intervention programmes need to be developed for immigrants of different countries of origin in accordance with the identified characteristics.

Hemorrhage is the most common preventable cause of death in both civilian and military trauma. There is no consensus regarding the appropriate fluid resuscitation protocol. Plasma, as a resuscitative fluid, has substantial benefits as a volume expander, owing to its relatively high oncotic pressure and its positive effect on trauma-induced coagulopathy by replenishing the lost coagulation factors, rather than diluting the casualty's remaining factors. The Israel Defense Force Medical Corps decided to use freeze-dried plasma (FDP) as the fluid of choice for casualties in hemorrhagic shock in the prehospital setting. The aim of our study is to compare the differences of coagulation, perfusion measurements, resource utilization, and outcome between casualties receiving FDP to casualties who did not receive FDP in the prehospital setting.This is a retrospective matched cohort study based on two groups of casualties (those treated with FDP vs. those without FDP treatment). The control group was compiled in three steps of precision for age, sex, mechanism of injury and maximum level of severity for each nine injured body regions. Data were collected from the IDF Trauma Registry and The National Israel Trauma Registry.The study group comprised 48 casualties receiving FDP and 48 controls with no differences in demographic, evacuation time, and injury characteristics. The FDP group demonstrated a lower level of hemoglobin (12.7 gr/dzl) (odds ratio [OR], 3.11; 95% confidence interval [CI], 1.10-8.80), lower level of international normalized ratio (1.1) (OR, 3.09; 95% CI, 1.04-9.14), and lower level of platelets (230 × 109/L) (OR, 3.06; 95% CI, 1.16-8.06). No other differences were found between the two groups.The use of FDP in the prehospital setting has logistic benefits and a positive effect on coagulation profile, with no other significant effects. Future studies need to be performed on larger groups to verify trends or nullify our hypotheses.Therapeutic, level IV.

Dog bites are a substantial public health concern. Rarely has hospitalizations resulting from dog bites been examined. We examined, at a national level, demographic and injury characteristics of dog-bites injuries requiring hospitalization to target prevention programs and policies for those who are at higher risk.Data on hospitalizations due to dog-bite injuries with an ICD9-CM E906.0 coding were extracted from the Israeli National Trauma Registry between 2009-2016. We calculated the annual incidence of hospitalized dog-bite injuries and compared rates by Chi-squared test. Mantel Haenszel chi-squared test and Dickey-Fuller time-series analysis were used to test linear age and temporal trends, respectively.Overall 986 persons were hospitalized for dog-bite injuries between 2009-2016. An increasing significant trend over the 8-year-period in the proportion of hospitalized dog-bite injuries among all trauma hospitalizations was revealed among children between 0 and 14 years old (p = 0.01). Children had also approximately twice the risk for dog-bite injuries compared to persons aged between 15 and 94 years old (relative risk [RR] = 1.89, 95% confidence interval [CI] = 1.35-2.66, p 0.0001); the 2016 (latest year) rate per 100,000 was significantly higher for boys than for girls (RR = 2.85, 95%CI = 1.57-5.19, p 0.0001); no gender differences were detected in the other age groups. Injury in the face/head/neck was most common in children between 0 and 14 years old (49.7%), specifically among the youngers (1, 1-3 and 4-5 year olds) compared with the 6-11 and 12-14 age groups (p 0.0001), with 4-fold-risk compared with persons aged between 15 and 94 years old (RR = 3.78, 95%CI, 3.01-4.75). There was no overall significant temporal trend in the annual incidence rates (from 1.84 (95%CI = 1.54-2.15) in 2009 to 1.54 (95%CI = 1.28-1.81) in 2016 per 100,000 population.Children younger than 15 years, with greater extent in boys than girls, represent the high-risk demographic group for dog bites. Prevention programs targeting at this group should be implemented and translated into an actual reduction in the incidence of dog-bites. In addition, an ongoing monitoring and reporting system specific for all dog-bites should be established in Israel, in order to better understand how to minimize the incidence of dog-bites and evaluate prevention efforts.

To examine whether hours of a day and days of a week influence injury pattern, means of evacuation, and hospital resource utilization. A study based on the Israeli National Trauma Registry of patients hospitalized due to injury between 2008 and 2015. Of 293,077 subjects included; 32.8% were admitted on weekends (weekend-days 16.7% and weekend-nights 16.1%), 20.0% on weeknights and 47.2% on weekdays. Compared with weekday admissions, weekend and weeknight admissions had higher risk of hospitalization from violence and fall-related injuries, but lower risk from road traffic injuries (RTI) except for weekend-day admissions adjusted for age, gender, and ethnicity. Hospitalization due to burn injuries was greater on weekends, particularly on weekend-days. Hospitalization for violence and burn injuries was greater on weekend-nights vs weeknights, while injuries from other unintentional causes were greater on weeknights than weekend-nights. Furthermore, patients admitted on weekends and weeknights were more likely to have severe and critical injuries, greater utilization of intensive care unit and to be referred for rehabilitation, but were less likely to receive prehospital emergency medical service. In stratified analyses, RTI-related hospitalization was greater on weekends among youth and adults aged 15–64 years, males and Arabs, while burn injuries were more likely among weekend admissions for children aged 0–14 years, female and Jews. Injury pattern and resource utilization are related to time. Therefore, injury prevention and intervention efforts should account for hours of a day and days of a week, particularly in relation with age, gender, and ethnicity.

Objective To determine if ethnic disparities exist with regard to the risk of injury and injury outcomes among elderly hospitalized casualties in Israel. Methods A retrospective study based on data from the Israeli National Trauma Registry between 2008 and 2017. Data included demographic, injury and hospitalization characteristics. Descriptive statistics and adjusted logistic regression were used to examine the differences between Jewish and Arab casualties, aged 65 and older. Result The study included 96,795 casualties. The proportion of elderly hospitalized casualties was 2.8 times greater than their proportion in the population (3.1 times greater among Jews and 2.1 times among Arabs). In comparison to Arabs, Jews suffered from a greater percentage of head injuries (10.5 and 8.9%, respectively for Jews and Arabs p

ObjectivesAn effective way to reduce casualties from earthquakes is to increase population preparedness. During 2011 to 2013, Israeli authorities executed 3 national-level earthquake awareness campaigns. We aimed to assess the impact of these campaigns on the populace and the ability of the campaigns to produce a cumulative effect throughout the study period.MethodsTwo surveys were conducted 2 weeks after the end of the first campaign and the third campaign in a similar randomly selected representative sample.ResultsExposure to the campaign proved to be a significant factor in increasing the knowledge of the respondents, giving a knowledge advantage of 1.5 times to respondents exposed to the campaign. However, the period of assessment proved to be an even more significant factor, with knowledge in 2013 being 2.3 times that in 2011. Additionally, a gap of up to 40% between the levels of trust and the perceived responsibility of respective authorities in the times of earthquake was found.ConclusionsThis study found an improvement in public knowledge regarding earthquake preparedness over the 3 years of the study. This may mean that an awareness campaign does not stand by itself, but should be part of an integrated long-term process in order to have a lasting effect on the population.

To assess the incidence and injury characteristics of hospitalized trauma patients diagnosed with TBI.A retrospective study of all injured hospitalized patients recorded in the National Trauma Registry at 19 trauma centres in Israel between 2002-2011. Incidence and injury characteristics were examined among children, adults and seniors.The annual incidence rate of hospitalized TBI for the Israeli population in 2011 was 31.8/100,000. Age-specific incidence was highest among seniors with a dramatic decrease in TBI-related mortality rate among them. Adults, in comparison to children and seniors, had higher rates of severe TBI, severe and critical injuries, more admission to the intensive care unit, underwent surgery, were hospitalization for more than 2 weeks and were discharged to rehabilitation. After adjusting for age, gender, ethnicity, mechanism of injury and injury severity score, TBI-related in-hospital mortality was higher among seniors and adults compared to children.Seniors are at high risk for TBI-related in-hospital mortality, although adults had more severe and critical injuries and utilized more hospital resources. However, seniors showed the most significant reduction in mortality rate during the study period. Appropriate intervention programmes should be designed and implemented, targeted to reduce TBI among high risk groups.

Background Although differences of opinion and controversies may arise, lessons learned from military conflicts often translate into improvements in triage, resuscitation strategies, and surgical technique. Our fully integrated national trauma system, providing care for both military and civilian casualties, necessitates close cooperation between all aspects of both sectors. We theorized that lessons learned from two regional conflicts over 8 years, with resultant improved triage, reduced hospital length of stay, and sustained low mortality would aid performance improvement and provide evidence of overall trauma system maturation. Methods We performed an 8 year, retrospective analysis of the Israeli National Trauma Registry prospective data base for all casualties presenting to level 1 and 2 trauma centers nationwide during an earlier conflict (W1) (7/12/06-8/14/06) and sought to compare results to those of a more recent war(W2), (7/08/14-08/26/14), as well as to compare our results to non-war civilian morbidity and mortality during the same time frame. Of particular interest were: casualty distributions, injuries/ISS, patterns of evacuation/triage, hospital length of stay, and mortality. Results Data on 919 war casualties was available for evaluation. Of 490 evacuated during W1, 341 (70%) were transferred to Level 1 centers, compared with 307 (72%) from the 429 casualties in W2. In W2, significantly more severe injuries (ISS ≥16) were evacuated directly to level 1 centers (42, 76% vs. 20, 43% respectively; p = 0.0007). W2 vs. W1 saw a significant increase in evacuations using helicopter (219,51% vs. 180,37%; p
