Characteristics of child abuse fatalities: Insights from a statewide violent death reporting system.

BACKGROUND: Child maltreatment fatalities are a significant public health issue. Case level characteristics of abuse-related deaths can increase our understanding of maltreatment fatalities and inform region-specific prevention initiatives. OBJECTIVE: Explore child abuse fatalities in the Illinois Violent Death Reporting System (IVDRS) for commonalities and distinctive features. METHODS, PARTICIPANTS AND SETTING: A mixed methods study was conducted using IVDRS data from 2015 to 2018. All fatalities with a homicide or undetermined manner of death among decedents 10 years old or younger were included. Both discrete and narrative data were analyzed separately for victim, suspect, circumstance, and household characteristics. RESULTS: Of the 106 deaths that met inclusion criteria, 74 % of homicide deaths (64/86) and 50 % of undetermined deaths (10/20) were due to abuse. Psychosocial characteristics most often identified in abusive deaths included family relationship problems, mental illness, and history of substance abuse. Other common characteristics included use of personal weapons or blunt instruments and death due to punishment. Including narrative data rather than discrete data alone identified 148 % more deaths with three characteristics commonly found in abusive deaths: history of abuse, shaken baby syndrome, and family history of violence. CONCLUSION: This study demonstrates the capability of multi-source state-level data to enrich our understanding of child abuse fatalities. Employing the narrative review method in other states using the National Violent Death Reporting System may increase the identification of abuse fatalities. Improved recognition and characterization of abuse fatalities has the potential to help address systemic factors involved and enhance targeted prevention efforts. WHAT IS KNOWN: Child abuse fatalities represent a significant and preventable public health issue in the United States. Case-specific characteristics are limited in national data sets, and their absence curtails prevention opportunities. WHAT THIS STUDY ADDS: State-wide reporting systems of violent deaths offer rich and multisource data regarding child abuse fatalities including detailed victim, suspect, circumstance, and household characteristics. This data can be used to enhance our knowledge of maltreatment fatalities and may inform region-specific public health and prevention initiatives.

Examining the relationship between long working hours and the use of prescription sedatives among U.S. workers.

OBJECTIVES: The prevalence of long working hours has been accompanied by a corresponding rise in sleep disorders. Sedative-hypnotic agents (SHAs), have been reported as the second most commonly misused drug class in the U.S. The key objective of this study was to examine the relationship between working hours on the use of sleep aids and medications with sedative properties. METHODS: The 2010-2019 Medical Expenditure Panel Survey data was utilized. SHAs and medications with sedative related properties (MSRPs) were identified. Furthermore, we employed different regression models ranging from multivariable linear regression, Tobit regression, Heckman regression, and multivariable logistic regression, to ensure consistency, robustness, and reliability of associations. RESULTS: Overall, a sample of 81,518 observations of full-time workers was analyzed. Working 56hours or more per week was significantly associated (p < 0.05) with an increased odds of using SHAs and MSRPs by 13% (Adjusted Odds Ratio, aOR =1.13, 95% Confidence Interval, CI=1.01:1.26) and 9% (aOR=1.09, 95% CI=1.03:1.16), respectively more than that among those who worked fewer hours. Females in our study had a higher likelihood (aOR=1.11, 95% CI=1.05:1.19) of using SHAs when compared to males. Also, professional services had the highest likelihood (aOR=1.31, 95% CI=1.14:1.50) of using SHAs. CONCLUSION: We found that long working hours were significantly associated with an elevated use of SHAs and MSRPs among U.S. workers. Specifically, female workers and individuals working in professional services had the highest likelihood of using sleep medications.

Sepsis Electronic Decision Support Screen in High-Risk Patients Across Age Groups in a Pediatric Emergency Department.

OBJECTIVE: This study aimed to compare the performance of a pediatric decision support algorithm to detect severe sepsis between high-risk pediatric and adult patients in a pediatric emergency department (PED). METHODS: This is a retrospective cohort study of patients presenting from March 2017 to February 2018 to a tertiary care PED. Patients were identified as high risk for sepsis based on a priori defined criteria and were considered adult if 18 years or older. The 2-step decision support algorithm consists of (1) an electronic health record best-practice alert (BPA) with age-adjusted vital sign ranges, and (2) physician screen. The difference in test characteristics of the intervention for the detection of severe sepsis between pediatric and adult patients was assessed at 0.05 statistical significance. RESULTS: The 2358 enrolled subjects included 2125 children (90.1%) and 233 adults (9.9%). The median ages for children and adults were 3.8 (interquartile range, 1.2-8.6) and 20.1 (interquartile range, 18.2-22.0) years, respectively. In adults, compared with children, the BPA alone had significantly higher sensitivity (0.83 [95% confidence interval {CI}, 0.74-0.89] vs 0.72 [95% CI, 0.69-0.75]; P = 0.02) and lower specificity (0.11 [95% CI, 0.07-0.19] vs 0.48 [95% CI, 0.45-0.51; P < 0.001). With the addition of provider screen, sensitivity and specificity were comparable across age groups, with a lower negative predictive value in adults compared with children (0.66 [95% CI, 0.58-0.74] vs 0.77 [95% CI, 0.75-0.79]; P = 0.005). CONCLUSIONS: The BPA was less specific in adults compared with children. With the addition of provider screen, specificity improved; however, the lower negative predictive value suggests that providers may be less likely to suspect sepsis even after automated screen in adult patients. This study invites further research aimed at improving screening algorithms, particularly across the diverse age spectrum presenting to a PED.

Children's Hospital Transfers From Referring Emergency Departments: Which Patients Bypassed the Pediatric Emergency Department?

OBJECTIVES: Children are increasingly transferred from emergency departments (EDs) to children's hospitals for inpatient care. The existing literature on the use of direct admission (DA) specifically among pediatric patients transferred from referring EDs remains sparse.The objective of this study was to identify demographic, clinical, and contextual factors associated with the use of direct-to-inpatient versus ED-to-inpatient admission among patients transferred to children's hospitals from EDs. METHODS: This was a retrospective chart review of nontrauma patients admitted to inpatient services at a single tertiary children's hospital after interfacility transfer from EDs between July 1, 2016, and June 30, 2017. Characteristics of the patient population and referring EDs were described; unadjusted associations between rates of DA and the demographic, clinical, and contextual variables of encounters were performed; and a logistic model quantified the relevant associations as odds ratios (ORs). RESULTS: Of 2939 study encounters, 78% resulted in DA. Among White patients, private insurance was associated with decreased direct admission (OR, 0.5; 95% confidence interval [CI], 0.4-0.8). Younger patients and patients with respiratory diagnoses (OR, 3.9; 95% CI, 2.8-5.3) had increased likelihood of DA. Patients with gastrointestinal diagnoses had decreased likelihood of DA (OR, 0.6; 95% CI, 0.4-0.7). CONCLUSIONS: At a tertiary hospital with a high rate of DA among patients transferred from other EDs, we identified factors that were associated with the use of direct versus ED admission. Our results identify specific populations in which future work could inform admission processes for interfacility transfers.

Emergency Department Visits for Suicidal Ideation and Self-Harm in Rural and Urban Youths.

OBJECTIVES: To compare emergency department (ED) visit rates for suicidal ideation and/or self-harm among youth by urban-rural location of residence. STUDY DESIGN: This is a retrospective analysis of ED visits for suicidal ideation and/or self-harm by youths aged 5-19 years (n = 297 640) in the 2016 Nationwide Emergency Department Sample, a representative sample of all US ED visits. We used weighted Poisson generalized linear models to compare population-based visit rates by urban-rural location of patient residence, adjusted for age, sex, and US Census region. For self-harm visits, we compared injury mechanisms by urban-rural location. RESULTS: Among patients with ED visits for suicidal ideation and/or self-harm, the median age was 16 years, 65.9% were female, 15.9% had a rural location of patient residence, and 0.1% resulted in mortality. The adjusted ED visit rate for suicidal ideation/or and self-harm did not differ significantly by urban-rural location. For the subset of visits for self-harm, the adjusted visit rate was significantly higher in small metropolitan (adjusted incidence rate ratio [aIRR], 1.39; 95% CI, 1.01-1.90), micropolitan (aIRR, 1.46; 95% CI, 1.10-1.93), and noncore areas (aIRR, 1.39; 95% CI, 1.03-1.87) compared with large metropolitan areas. When stratified by injury mechanism, ED visit rates for self-inflicted firearm injuries were higher among youths living in rural areas compared with those in urban areas (aIRR, 3.03; 95% CI, 1.32-6.74). CONCLUSIONS: Compared with youths living in urban areas, youths living in rural areas had higher ED visit rates for self-harm, including self-inflicted firearm injuries. Preventive approaches for self-harm based in community and ED settings might help address these differences.

Urban versus rural setting as a predictor of injury type and severity among pediatric pedestrians: using a database derived from state-wide crash data and hospital discharge data in Illinois.

We obtained and linked data from the Illinois Department of Transportation and the Illinois Hospital Discharge Data System 2008 - 2015. We evaluated differences in demographic characteristics, injury severity and type among cases and examined associations among injury type, severity, and crash location. There were 11,303 injured pedestrians under 19 years of age and 46% matched to hospital data. Demographic characteristics were similar to unlinked cases. Among linked cases, fractures, traumatic brain injury, open wound or amputation, and internal organ injuries occurred more often in rural areas (p < 0.001), as were more severe injuries (p < 0.001). Mild injury and soft tissue injuries occurred more often in urban areas (p < 0.001). These data can inform targeted interventions for injury reduction. Preliminary investigations found that more severe injuries and specific injury types are more likely to occur in rural versus urban settings. Our combined database approach may be extended to other databases.

Variance estimation in tests of clustered categorical data with informative cluster size.

In the analysis of clustered data, inverse cluster size weighting has been shown to be resistant to the potentially biasing effects of informative cluster size, where the number of observations within a cluster is associated with the outcome variable of interest. The method of inverse cluster size reweighting has been implemented to establish clustered data analogues of common tests for independent data, but the method has yet to be extended to tests of categorical data. Many variance estimators have been implemented across established cluster-weighted tests, but potential effects of differing methods on test performance has not previously been explored. Here, we develop cluster-weighted estimators of marginal proportions that remain unbiased under informativeness, and derive analogues of three popular tests for clustered categorical data, the one-sample proportion, goodness of fit, and independence chi square tests. We construct these tests using several variance estimators and show substantial differences in the performance of cluster-weighted tests based on variance estimation technique, with variance estimators constructed under the null hypothesis maintaining size closest to nominal. We illustrate the proposed tests through an application to a data set of functional measures from patients with spinal cord injuries participating in a rehabilitation program.

Interrater Reliability of the Pediatric Neuromuscular Recovery Scale for Spinal Cord Injury.

Background: In synergy with the mounting scientific evidence for the capacity of recovery after spinal cord injury (SCI) and training, new evidence-based therapies advancing neuromuscular recovery are emerging. There is a parallel need for outcome instruments that specifically address recovery. The Pediatric Neuromuscular Recovery Scale (Pediatric NRS) is one example with established content validity to assess neuromuscular capacity within task performance. Objective: The objective of this study was to determine interrater reliability of the Pediatric NRS to classify motor capacity in children after SCI. Methods: Pediatric physicians (3), occupational therapists (5), and physical therapists (6) received standardized training in scoring the scale, then rated video assessments of 32 children post SCI, 2-12 years of age, 78% non-ambulatory. Interrater reliability was analyzed using Kendall coefficient of concordance for individual Pediatric NRS items and overall score. Results: The interrater reliability coefficient was determined to be near 1 for the overall Pediatric NRS score (ICC = 0.966; 95% CI, 0.89-0.98). Twelve of 16 individual items exhibited high concordance coefficients (Kendall's W ≥ 0.8) and four items demonstrated concordance coefficients, < 0.8 and > 0.69. Interrater reliability was equivalent among groups defined by age and neurological level, but lower among non-ambulatory individuals. Conclusion: Strong interrater reliability was demonstrated by pediatric clinicians who scored children with SCI using the Pediatric NRS.

A log rank test for clustered data with informative within-cluster group size.

The log rank test is a popular nonparametric test for comparing survival distributions among groups. When data are organized in clusters of potentially correlated observations, adjustments can be made to account for within-cluster dependencies among observations, eg, tests derived from frailty models. Tests for clustered data can be further biased when the number of observations within each cluster and the distribution of groups within cluster are correlated with survival times, phenomena known as informative cluster size and informative within-cluster group size. In this manuscript, we develop a log rank test for clustered data that adjusts for the potentially biasing effect of informative cluster size and within-cluster group size. We provide the results of a simulation study demonstrating that our proposed test remains unbiased under cluster-based informativeness, while other candidate tests not accounting for the clustering structure do not properly maintain size. Furthermore, our test exhibits power advantages under scenarios in which traditional tests are appropriate. We demonstrate an application of our test by comparing time to functional progression between groups defined initial functional status in a spinal cord injury data set.

Validity of the Neuromuscular Recovery Scale: a measurement model approach.

OBJECTIVE: To determine how well the Neuromuscular Recovery Scale (NRS) items fit the Rasch, 1-parameter, partial-credit measurement model. DESIGN: Confirmatory factor analysis (CFA) and principal components analysis (PCA) of residuals were used to determine dimensionality. The Rasch, 1-parameter, partial-credit rating scale model was used to determine rating scale structure, person/item fit, point-measure item correlations, item discrimination, and measurement precision. SETTING: Seven NeuroRecovery Network clinical sites. PARTICIPANTS: Outpatients (N=188) with spinal cord injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: NRS. RESULTS: While the NRS met 1 of 3 CFA criteria, the PCA revealed that the Rasch measurement dimension explained 76.9% of the variance. Ten of 11 items and 91% of the patients fit the Rasch model, with 9 of 11 items showing high discrimination. Sixty-nine percent of the ratings met criteria. The items showed a logical item-difficulty order, with Stand retraining as the easiest item and Walking as the most challenging item. The NRS showed no ceiling or floor effects and separated the sample into almost 5 statistically distinct strata; individuals with an American Spinal Injury Association Impairment Scale (AIS) D classification showed the most ability, and those with an AIS A classification showed the least ability. Items not meeting the rating scale criteria appear to be related to the low frequency counts. CONCLUSIONS: The NRS met many of the Rasch model criteria for construct validity.

Test-retest reliability of the Neuromuscular Recovery Scale.

OBJECTIVE: To determine the test-retest reliability of the Neuromuscular Recovery Scale (NRS), a measure to classify lower extremity and trunk recovery of individuals with spinal cord injury (SCI) to typical preinjury performance of functional tasks without use of external and behavioral compensation. DESIGN: Multicenter observational study. SETTING: Five outpatient rehabilitation clinics. PARTICIPANTS: Physical therapists (N=13), trained and competent in conducting NRS, rated outpatients with SCI (N=69) using the NRS. Testing occurred on 2 days, separated by 24 to 48 hours, on the same patient by the same therapist. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Spearman rank correlation coefficients to compare NRS results. The NRS scores of motor performance were based on normal, preinjury function on 11 items: 4 treadmill-based items (standing and stepping), 7 overground/mat items (sitting, sit-up, reverse sit-up, trunk extension, sit to stand, standing, walking). RESULTS: Test-retest reliability was very strong for the NRS items. Ten of the 11 items exhibited Spearman correlation coefficients ≥.92, and lower bounds of the 95% confidence intervals (CIs) for these items met or exceeded .83. The exception was stand retraining (ρ=.84; 95% CI, .68-.96). The test-retest reliability of the measurement model-derived summary score was very strong (ρ=.99; 95% CI, .96-.99). CONCLUSIONS: The NRS had excellent test-retest reliability when conducted by trained therapists in adults with chronic SCI across all levels of injury severity. All raters had undergone standardized training in use of the NRS. The minimal requirement of training to achieve test-retest reliability has not been established.

Interrater reliability of the Neuromuscular Recovery Scale for spinal cord injury.

OBJECTIVE: To determine the interrater reliability of the Neuromuscular Recovery Scale (NRS), an outcome measure designed to classify people with complete or incomplete spinal cord injury (SCI) into 4 phase-of-injury groups by assessing motor performance based on normal preinjury function and disallowing use of compensation for 4 treadmill-based items and 6 overground/mat items. DESIGN: Masked comparison, multicenter observational study. SETTING: Outpatient rehabilitation. PARTICIPANTS: Raters (N=14) and a criterion standard expert assigned scores to 10 video NRS assessments of persons with SCI. The raters were volunteers from the NeuroRecovery Network. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Interrater reliability measured with the Kendall coefficient of concordance (W). RESULTS: Interrater reliability was generally strong (W=.91-.98; 95% confidence interval [CI], .65-.99), while lower reliability occurred for treadmill stand retraining (W=.87; 95% CI, .06-1) and seated trunk extension (W=.82; 95% CI, .28-.94). Less experienced raters assigned slightly lower scores than the expert for most items, but the difference was less than half a point and did not weaken concordance. CONCLUSIONS: NRS had strong interrater reliability, a necessary first step in establishing its utility as a clinical and research outcome measure.

Evaluation of cerebral oxygenation during procedural sedation in children using near infrared spectroscopy.

STUDY OBJECTIVE: We evaluate the utility of near infrared spectroscopy monitoring and its correlation to conventional respiratory monitors during changes in cardiorespiratory characteristics during pediatric procedural sedation. METHODS: In this prospective observational study of 100 children, cerebral oxygenation (rSO(2)), pulse oximetry (SpO(2)), and end-tidal carbon dioxide (etco(2)) were monitored continuously. Values were manually recorded at least every 3 minutes from baseline until 30 minutes after sedative administration, resulting in 1,515 triplicate (simultaneous near infrared spectroscopy/etco(2)/SpO(2)) measurements. Correlations between conventional monitoring characteristics (SpO(2) and etco(2)) and rSO(2) were determined, with focus during adverse cardiorespiratory events. RESULTS: Cerebral oxygenation remained normal in 1,483 of 1,515 measurements (97.9%). rSO(2) decreased significantly during 3 of 13 hypoxic events occurring in 13 patients and during 5 of 17 hypercarbic events occurring in 8 patients, with 15 measurements of greater than 20% decrease from baseline. Cerebral oxygenation increased transiently in 88% of children. During 31 cerebral desaturation recordings, 3 hypoxic recordings (9.3%, always in combination with hypercarbia) and 5 hypercarbic recordings (15.6%) were observed, whereas in 23 (74.2%), cardiorespiratory characteristics were unchanged. There was poor correlation between rSO(2) and both SpO(2) and etco(2), with correlation coefficients of 0.05 (95% confidence interval 0.04 to 0.07) and 0.01 (95% confidence interval -0.01 to 0.02), respectively. CONCLUSION: Cerebral oxygenation as measured by near infrared spectroscopy demonstrated few significant negative changes during pediatric procedural sedation. Transient cardiorespiratory events seldom altered rSO(2), with hypercarbia having a greater effect than hypoxemia. However, cerebral desaturations frequently occurred without associated cardiorespiratory changes.

The anatomic relationship of femoral vein to femoral artery in euvolemic pediatric patients by ultrasonography: implications for pediatric femoral central venous access.

BACKGROUND: Knowledge of the femoral vein (FV) anatomy in pediatric patients is important in the selection of appropriate size central line catheters as well as the approach to central venous access. This knowledge may avoid potential complications during central line access. OBJECTIVES: To describe the relationship of the FV to the femoral artery (FA). To measure FV diameter and FV depth using ultrasonography (US) in newborns, infants, and children up to 9 years of age. METHODS: This study was a prospective descriptive study at a tertiary care children's hospital. A convenience sample of euvolemic children was enrolled aged 0-9 years presenting to an urban pediatric emergency department. All patients underwent a standardized US evaluation using a Sonosite Titan bedside machine by a single emergency physician. The FA and FV were identified by four criteria: relative positions, FV compressibility, FV enlargement by Valsalva maneuver, and absence of FV pulsatility. The position of the FV relative to the FA was described as being completely overlapped by the FA, having partial (<50%) overlap by the FA, and having no overlap by the FA. The FV depth was measured from the skin to the superior border of the vein using the US machine's caliper function. RESULTS: A total of 84 patients were studied. The FV was found to be completely overlapped by the FA in 8% of subjects and partially overlapped by the FA in 4% of subjects. The mean FV diameter ranged from 4.5 mm in young infants to 10.8 mm in patients 9 years of age. The mean FV depth ranged from 6.5 mm in neonates to 11.2 mm in patients 9 years of age. CONCLUSIONS: External landmarks were not always predictive of internal anatomy. The FV was completely or partially overlapped by the FA in 12% of cases. Thus, visualization of femoral vessels should be recommended prior to attempting pediatric femoral central venous access.

Effectiveness of oxycodone, ibuprofen, or the combination in the initial management of orthopedic injury-related pain in children.

OBJECTIVE: Orthopedic injuries comprise a majority of the indications for analgesia in the emergency department. Oxycodone and ibuprofen have demonstrated efficacy for this indication, but no studies have compared these drugs in children. Our objective was to investigate the effectiveness of oxycodone, ibuprofen, or their combination for the management of orthopedic injury-related pain in children. METHODS: This prospective, randomized, double-blinded, clinical trial compared the effectiveness of oxycodone, ibuprofen, and the combination in children (age, 6-18 years), with pain from a suspected orthopedic injury. Subjects were block-randomized to receive 1 of the 3 treatment regimens. Pain was assessed with the Faces Pain Scale (FPS) and Visual Analog Scale at baseline, postimmobilization, 30, 60, 90, and 120 minutes postmedication. The change in the FPS score over time was compared between the 3 treatment groups using a generalized estimating equation model. RESULTS: Although all 3 treatment groups demonstrated a decrease in the FPS score over time, there were no significant differences between the groups. Among the 66 total children enrolled in the 3 treatment groups, there were no statistically significant differences in demographics or injury characteristics. There were 28 subjects with fractures. Immobilization of the injury demonstrated a significant reduction in the FPS score. Subjects in the combination treatment group reported more adverse effects. CONCLUSIONS: Oxycodone, ibuprofen, and the combination all provide effective analgesia for mild-to-moderate orthopedic injuries in children. Oxycodone or ibuprofen, alone, can be given, thereby avoiding the increase in adverse effects when given together.

Adjuvant chemotherapy for breast cancer: how presentation of recurrence risk influences decision-making.

PURPOSE: The purpose of this study was to examine the impact of four methods of communicating survival benefits on chemotherapy decisions. We hypothesized that the four methods of communicating mathematically equivalent risk information would lead to different chemotherapy decisions. METHODS: Each participant received two hypothetical scenarios regarding their mother (a postmenopausal woman with an invasive, lymph node-negative, hormone receptor-positive breast cancer) and was asked to decide whether they would encourage their mother to take chemotherapy in addition to surgery and tamoxifen. In the part 1, participants received one of four methods of describing the chemotherapy survival benefit: (1) relative risk reduction, (2) absolute risk reduction, (3) absolute survival benefit, or (4) number needed to treat. In part 2, each participant received all four methods. Following each decision, participants were asked to rate their confidence and confusion regarding their decision. RESULTS: Participants included 203 preclinical medical students. In part 1, participants who received relative risk reduction information were significantly more likely to endorse chemotherapy. In part 2, there were no treatment decision differences when participants received all four methods of communicating survival benefits of chemotherapy. However, receiving all four methods led to significantly higher ratings of confusion. In deciding on endorsing chemotherapy, participants understood the information best when presented with data in the absolute survival benefit format. CONCLUSION: These results support the hypothesis that the method used to present information about chemotherapy influences treatment decisions. Absolute survival benefit is the most easily understood method of conveying the information regarding benefit of treatment.
