Variability in pediatric injury patterns by age and ethnic groups in Israel

The trend of fall-related mortality at national and provincial levels in Iran from 1990 to 2015

Falls are one of the major causes of unintentional injuries. Understanding the epidemiology of fall-related mortality helps to identify the root causes of this event and planning preventive strategies to inhibit falls. The aim of this study was to assess the trend of fall-related mortality rate and its epidemiological patterns based on sex and age-groups at national and subnational levels in Iran during the years 1990 to 2015. All data were gathered from Death Registration Systems, cemetery databases of Tehran and Isfahan, the Demographic and Health Survey of 2000 and three rounds of national population and housing censuses. The age-standardized death rate (ASDR) due to falls per 100,000 people decreased from 2.61 (95% Uncertainty Interval (UI): 1.94-3.51) in 1990 to 2.13 (1.62-2.80) in 2015 at national level. Males were at higher risk of death due to falls than females. Our data showed that the elderly population was at higher risk of death due to falls and individuals less than 4-year old had the highest fall-related mortality rate among children and adolescents. Our data should be used to accelerate interventions to reduce fall-related mortality.

Mechanisms of accidental fall injuries and involved injury factors: a registry-based study

Background

Falls are the leading cause of injury-related morbidity and mortality worldwide, but fall injury circumstances differ by age. We studied the circumstances of accidental fall injuries by age in Shenkursk District, Northwest Russia, using the data from the population-based Shenkursk Injury Registry.

Methods

Data on accidental fall injuries (hereafter: fall injuries) occurring in January 2015–June 2018 were extracted from the Shenkursk Injury Registry (N = 1551) and categorized by age group (0–6, 7–17, 18–59, and 60+ years). The chi-square test and ANOVA were used to compare descriptive injury variables across age groups, and a two-step cluster analysis was performed to identify homogeneous groups of fall injuries by preceding circumstances.

Results

Half of recorded fall injuries in the 0–6 year age group occurred inside dwellings (49%). The largest cluster of falls (64%) mainly included climbing up or down on home furnishings. In the 7–17 year age group, public outdoor residential areas were the most common fall injury site (29%), and the largest cluster of falls (37%) involved physical exercise and sport or play equipment. Homestead lands or areas near a dwelling were the most typical fall injury sites in the age groups 18–59 and 60+ years (31 and 33%, respectively). Most frequently, fall injury circumstances in these groups involved slipping on ice-covered surfaces (32% in 18–59 years, 37% in 60+ years).

Conclusion

The circumstances of fall injuries in the Shenkursk District varied across age groups. This knowledge can be used to guide age-specific preventive strategies in the study area and similar settings.

Big Data-Driven Approach for Health Inequalities in Foreign Patients with Injuries Visiting Emergency Rooms

Objectives

Foreign patients are more likely to receive inappropriate health service in the emergency room. This study aimed to investigate whether there is health inequality between foreigners and natives who visited emergency rooms with injuries and to examine its causes.

Methods

We analyzed clinical data from the National Emergency Department Information System database associated with patients of all age groups visiting the emergency room from 2013 to 2015. We analyzed data regarding mortality, intensive care unit admission, emergency operation, severity, area, and transfer ratio.

Results

A total of 4,464,603 cases of injured patients were included, of whom 67,683 were foreign. Injury cases per 100,000 population per year were 2,960.5 for native patients and 1,659.8 for foreign patients. Foreigners were more likely to have no insurance (3.1% vs. 32.0%, p < 0.001). Serious outcomes (intensive care unit admission, emergency operation, or death) were more frequent among foreigners. In rural areas, the difference between serious outcomes for foreigners compared to natives was greater (3.7% for natives vs. 5.0% for foreigners, p < 0.001). The adjusted odds ratio for serious outcomes for foreign nationals was 1.412 (95% confidence interval [CI], 1.336–1.492), and that for lack of insurance was 1.354 (95% CI, 1.314–1.394).

Conclusions

Injured foreigners might more frequently suffer serious outcomes, and health inequality was greater in rural areas than in urban areas. Foreign nationality itself and lack of insurance could adversely affect medical outcomes.

The epidemiology of wrist and hand injury in two hospitals in Jerusalem: substantial differences between population subgroups

Background

Wrist and hand injuries are common and constitute a major economic burden. General injury prevention programs have failed to demonstrate a decrease in injury rates. We hypothesized that there are differences in injury patterns in culturally diverse subpopulations of a metropolitan area treated within the same medical system, which may partly explain the difficulties associated with injury prevention.

Methods

We conducted a survey of patients admitted to emergency departments of two hospitals in Jerusalem for wrist and hand injuries during a 3 month period. Patients were asked to complete a questionnaire regarding demographic data, injury type and mechanism. Injury type and mechanism were then compared for age, gender, level of education and degree of religiosity.

Results

The questionnaire was completed by 799 patients (response rate 62%; 75% male; average age 27). Thirty-one percent reported they were injured at work, 33% at home and 36% during leisure activities. Data analysis showed that several subpopulations were found to be at risk as compared to their corresponding groups and relative proportion in the overall population of the city. These included contusions after falls in non-ultra-Orthodox Jewish women aged 65 years and over, crush injuries in ultra-Orthodox Jews under the age of 10 (53% vs. 14% for non ultra-Orthodox Jews, respectively) and Muslim teens. Muslims were injured more, especially at work, in comparison to their relative proportion in the population as a whole.

Conclusion

Different subpopulations at risk and different injury patterns of wrist and hand injuries were found in this culturally heterogeneous population. Awareness of these differences may be the first step when designing specific injury prevention programs in a culturally diverse population. A combined effort of community leaders and government agencies is needed to deal with the specific populations at risk, although legislation may be needed to limit some of the risks such as teens and specific work related hazards and exposures.

Children's Improvement of a Motor Response during Backward Falls through the Implementation of a Safe Fall Program

The World Health Organization has warned that, in children, the second cause of death from unintentional injuries are falls. The objective of this study was to analyze the motor response of primary schoolchildren when a backwards fall occurs. These analyses occurred before and after interventions of the Safe Fall program, which aims to teach safe and protected ways of backward falling. A quasi-experimental research design was used, with a sample of 122 Spanish (Sevillian) schoolchildren in the 10⁻12 age bracket. The INFOSECA ad-hoc observation scale was used for data collection: this scale registers 5 essential physical reactions throughout the process of a safe and protected backwards fall. After that, a number of descriptive, correlational and contrast statistics were applied. The value used in the McNemar test to establish statistical significance was p < 0.05. Results showed that over 85% of students had developed the competence to correctly perform all five physical motions that allow for a safer backward fall. The teaching of safe and protected techniques for falling backwards in child population in Primary Education is possible through the implementation of the Safe Fall program in Physical Education classes, which can help making falls safer, diminishing the risk and severity of the injuries they cause.

Age, Ethnicity, and Socioeconomic Factors Impacting Infant and Toddler Fall-Related Trauma

OBJECTIVE

To characterize trauma-related falls in infants and toddlers aged 0 to 3 years over a 4-year period and develop a risk stratification model of causes of fall injuries.

METHODS

Data on falls of 0 to 3 year olds from 2009 to 2012 were identified from a Jerusalem tertiary hospital trauma registry (N = 422) and the National Trauma Registry of Israel (N = 4,131).

RESULTS

Almost half of falls occurred during the first year of life, and 57% of the children were Jewish. The majority of the children lived in low socioeconomic environments, both in the Jewish (59.2%) and Arab (97.6%) samples. Most (74%) of the falls resulted in head injury. A classification and regression tree analysis indicated that falls from furniture were the leading cause of injury in 0 to 12 month olds (estimated probability of 37.9%), whereas slipping is the leading cause in 13 to 36 month olds (estimated probability of 38.4%). Age and ethnicity emerged as the leading predictors of the nature of a fall; Injury Severity Score and the child's sex were secondary. Compared with the national data, Jerusalem children had a higher incidence of falls from buildings (9.3%; 2.4%), a higher moderate-severe Injury Severity Score (>16), a higher incidence of traumatic brain injury, and a longer hospital length of stay (P < 0.001).

CONCLUSIONS

The leading determinants of fall injuries in children below the age of 3 years are age, ethnicity, and low socioeconomic status. Future outreach community interventions should target these risk groups and be tailored to their defining characteristics.

Characteristics and circumstances of injuries vary with ethnicity of different population groups living in the same country

OBJECTIVE

To examine whether characteristics and circumstances of injuries are related to ethnicity.

DESIGN

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.

RESULTS

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.

CONCLUSION

Targeted intervention programmes need to be developed for immigrants of different countries of origin in accordance with the identified characteristics.

[Epidemiology and risk factors in injuries due to fall in infants under one year-old]

OBJECTIVES

To describe the epidemiological characteristics of unintentional injuries due to falls in children under one year and to analyse the risk factors associated with severe injuries.

PATIENTS AND METHODS

This multicentre, observational and cross-sectional study included all children less than one year treated for unintentional fall in the Emergency Departments of 8 Spanish Hospitals, belonging to the «Unintentional Paediatric Injury Workshop» of the Spanish Paediatric Emergency Society, between March 1st, 2014 and February 28th, 2015.

RESULTS

Out of 289,887 emergency department cases, 1,022 were due to unintentional falls. The median age was 8 months and 52.5% were males. Fall injuries were more frequent among children aged 9-12 months (37.6%), and 83.5% occurred at home. The most common mechanism was fall from nursery equipment (69.4%), and 47.8% occurred from a height under 50cm. More than two-thirds (68%) of falls were witnessed, but in half of the cases (329) the caregiver was not in area. Serious injuries were seen in 12% of cases. In this study, a fall height greater than 50cm, falls in the street, from the arms of the carer, and from the stairs were identified as independent risk factors for worse outcomes.

CONCLUSIONS

The most serious injuries occur in children <3 months and from a height of >50cm, though not related to unwitnessed falls. Because the most common serious injury mechanism is the fall from the arms of the carer, from stairs, and falls in the street, these facts should be highlighted in order to avoid morbidity.

Is ethnic density associated with risk of child pedestrian injury? A comparison of inter-census changes in ethnic populations and injury rates

OBJECTIVES

Research on inequalities in child pedestrian injury risk has identified some puzzling trends: although, in general, living in more affluent areas protects children from injury, this is not true for those in some minority ethnic groups. This study aimed to identify whether 'group density' effects are associated with injury risk, and whether taking these into account alters the relationship between area deprivation and injury risk. 'Group density' effects exist when ethnic minorities living in an area with a higher proportion of people from a similar ethnic group enjoy better health than those who live in areas with a lower proportion, even though areas with dense minority ethnic populations can be relatively more materially disadvantaged.

DESIGN

This study utilised variation in minority ethnic densities in London between two census periods to identify any associations between group density and injury risk. Using police data on road traffic injury and population census data from 2001 to 2011, the numbers of 'White,' 'Asian' and 'Black' child pedestrian injuries in an area were modelled as a function of the percentage of the population in that area that are 'White,' 'Asian' and 'Black,' controlling for socio-economic disadvantage and characteristics of the road environment.

RESULTS

There was strong evidence (p < 0.001) of a negative association between 'Black' population density and 'Black' child pedestrian injury risk [incidence (of injury) rate ratios (IRR) 0.575, 95% CI 0.515-0.642]. There was weak evidence (p = 0.083) of a negative association between 'Asian' density and 'Asian' child pedestrian injury risk (IRR 0.901, 95% CI 0.801-1.014) and no evidence (p = 0.412) of an association between 'White' density and 'White' child pedestrian injury risk (IRR 1.075, 95% CI 0.904-1.279). When group density effects are taken into account, area deprivation is associated with injury risk of all ethnic groups.

CONCLUSIONS

Group density appears to protect 'Black' children living in London against pedestrian injury risk. These findings suggest that future research should focus on structural properties of societies to explain the relationships between minority ethnicity and risk.

Controlling for exposure changes the relationship between ethnicity, deprivation and injury: an observational study of child pedestrian injury rates in London

BACKGROUND

Research has suggested that inequalities in risk exposure may help explain identified ethnic inequalities in child pedestrian injury risk. However, addressing risk exposure in epidemiological research presents theoretical and methodological challenges. This article conceptualises the risk of child pedestrian injury as related to both exposure levels (the quantity of time children spend as pedestrians) and the probability of a hazard where that exposure takes place (the quality of the road environment).

OBJECTIVE

To investigate the sensitivity of results on ethnic inequalities in child pedestrian injury risk in London to control for exposure and hazard levels.

METHODS

Using police records of injury 2000-2009, we modelled the relationship between ethnicity, deprivation and child pedestrian injury rates in London using characteristics of the road environment to control for hazard levels and restricting the analysis to the time of the weekday morning commute (7.00-9.00 am), when most children must make a journey to school, to control for exposure levels.

RESULTS

Controlling for risk exposure in this way fundamentally changed the nature of the relationship between ethnicity, deprivation and child pedestrian injury. During the time of the morning commute to school, 'Black' children were found to have higher pedestrian injury rates in the least-deprived areas.

CONCLUSIONS

To inform effective strategies for reducing injury inequality, it is vital that exposure to risk is both acknowledged and considered.

Base excess as a predictor for injury severity in pediatric trauma patients

BACKGROUND

Base excess is considered a predictor of mortality and severity of injury in trauma patients. Base excess had been widely examined in different settings. Only few studies have examined the role of base excess in pediatric trauma patients.

OBJECTIVE

To evaluate the value of admission base excess in pediatric trauma patients with respect to intensive care unit (ICU) admission rate and length of hospital stay.

METHODS

A retrospective study of pediatric trauma patients was conducted at a Level II trauma center. All patients aged 0-16 years for which a trauma team was activated over the years 2006-2009 were included. Study database included admission base excess, mechanism of injury, location and nature of injury, injury severity score, length of hospital stay, and ICU admission.

RESULTS

The study group consisted of 359 patients. There was a weak linear correlation between admission base excess, length of stay in the hospital, and ICU admission. Base excess seemed to show a stronger correlation for the youngest age group (0-6 years) and no correlation for the middle age group. There was a positive but weak correlation (R Spearman = 0.26) between admission base excess and Injury Severity Score (ISS). However, 40% of the children with an ISS score >25 had normal admission base excess values. The area under the curve of the receiver operating characteristic curves of base excess for predicting ICU admission was 0.66.

CONCLUSIONS

The admission base excess in pediatric trauma patients seems to be a weak prognostic factor in our facility.

Ethnicity and road traffic injuries: differences between Jewish and Arab children in Israel

OBJECTIVE

To examine the differences and characteristics of road traffic injuries (RTIs) among Jewish and Arab children, ages 0-17 years, in Israel.

DESIGN

A retrospective study based on data from the Israeli National Trauma Registry between 2001 and 2010. This study relates specifically to traffic-related hospitalizations among children ages 0-17 years. Data include demographic, injury, and hospitalization characteristics. Descriptive statistics and adjusted logistic regression were used to examine the differences of RTIs between the two ethnic groups.

RESULTS

A total of 18,884 children were included, of which Arab children comprised 38.2% of the total and 44.1% of the severely injured. Among Arab children 41.8% were pedestrians compared to 33.4% among Jewish children (p<0.0001). Arab children were younger, had more severe injuries and more traumatic brain injury (TBI) compared to Jewish children. Adjusted logistic regression analysis shows that the probability of an Arab child, relative to a Jewish child, to undergo surgical procedures was 1.2 (p<0.0001), to be hospitalized in intensive care units (ICUs) was 0.8 (p=0.003), and to be transferred to rehabilitation was 0.5 (p<0.0001). There was no significant difference in inpatient mortality between the two ethnic groups.

CONCLUSIONS

Arab children in Israel are more likely to be hospitalized due to road accidents in comparison to Jewish children. Intervention programs should focus on Arab children and their unique characteristics.

The role of community in pediatric injury

Cultural variations between communities may impact injury rates, especially among children. We conducted a retrospective study of three communities in Israel using data from the Israel National Trauma Registry (1998-2007). Pediatric injury hospitalization rates in urban communities with varied levels of socio-economic status (low, medium, and high) were compared for all injuries and cause-specific injuries. Age-standardized and age-specific rates were calculated. Age-standardized injury hospitalization rates were lowest for the low socio-economic status (SES) community (299.7, 95% confidence interval [CI] 289.8-309.6) compared to the medium SES (658.2, 95% CI 629.1-687.3) and high SES (443.7, 95% CI 422.2-465.3) communities. Similar rates were observed for injuries from falls, transportation, accidental striking and intentional causes. For example, rate ratios for falls were 149.1 (95% CI 142.0-156.2), 340.8 (95% CI 319.5-362.1) and 245.7 (229.9-261.5) in the low, medium and high SES communities, respectively. Deviations from these overall trends were noted, however, for pedestrian injuries and burns that were relatively higher in the low SES community and injuries from motorized vehicles that were greater among children living in the high SES community. These results suggest that strong social capital is associated with reduced pediatric injury risks regardless of community wealth. However, targeted interventions for reducing injuries in at-risk populations that rely solely on injury rates may omit culturally distinct communities and overlook their uneven burden to the trauma care system.

'Race' or place? Explaining ethnic variations in childhood pedestrian injury rates in London

There is a substantial literature on socio-economic inequalities in injury rates, but less on ethnic differences. Using police records of road injuries to examine the relationships between pedestrian injury, area deprivation and ethnicity we found that, in London, children categorised as 'Black' had higher injury rates than those categorised as 'White' or 'Asian', and that living in less deprived areas did not protect 'Black' children from higher risk. Ethnic differences in injury rates cannot be explained by minority ethnic status or area deprivation, but are likely to result from the complex ways in which ethnicity shapes local experiences of exposure to injury risk.
