Characterizing Point-of-Care Ultrasound Credentialing in Pediatric Emergency Departments.

OBJECTIVE: It is unclear which pediatric emergency departments (PEDs) have a point-of-care ultrasound (POCUS) credentialing process or if this process is consistent per expert guidelines. Our objective was to describe formalized POCUS credentialing processes across PEDs that are active in the pediatric emergency medicine POCUS (P2) Network. METHODS: A survey was developed from nationally recommended credentialing guidelines. This anonymous survey was sent out to the P2 Network comprising more than 230 members involved in pediatric POCUS. The survey was analyzed using descriptive analysis with counts and percentages. RESULTS: A total of 36 PEDs responded to the survey. All departments had a faculty member in charge of maintaining the credentialing process, and all faculty members had POCUS education available; 88.6% of education was scheduled didactics or bedside teaching. There were 80.6% of PEDs that had a process for internally credentialing faculty. Some PEDs offered protected education for POCUS, however, 44.8% had <50% of their faculty credentialed. There were 4 PEDs that offered incentives for completion of POCUS credentialing including salary bonuses; only 1 offered shift buy down as incentive. That PED had 100% of its faculty credentialed. All PEDs performed quality assurance on POCUS scans done in the ED, most done weekly. Billing for scans occurred in 26 PEDs. Skin/soft tissue and focused assessment with sonography for trauma were the 2 most common applications credentialed. CONCLUSIONS: Among PEDs surveyed, there was a lack of standardization of POCUS resources and components of credentialing. Incentives may be beneficial in improving credentialing faculty and standardizing the credentialing process.

Ultrasound-Guided Regional Anesthesia of the Femoral Nerve in the Pediatric Emergency Department.

OBJECTIVES: Femur fractures are painful, and use of systemic opioids and other sedatives can be dangerous in pediatric patients. The fascia iliaca compartment nerve block and femoral nerve block are regional anesthesia techniques to provide analgesia by anesthetizing the femoral nerve. They are widely used in adult patients and are associated with good effect and reduced opioid use. Ultrasound (US) guidance of nerve blocks can increase their safety and efficacy. We sought to report on the use and safety of US-guided regional anesthesia of the femoral nerve performed by emergency physicians for femur fractures in 6 pediatric emergency departments. METHODS: Records were queried at 6 pediatric EDs across North America to identify patients with femur fractures managed with US-guided regional anesthesia of the femoral nerve between January 1, 2016, and May 1, 2021. Data were abstracted regarding demographics, injury pattern, nerve block technique, and analgesic use before and after nerve block. RESULTS: Eighty-five cases were identified. Median age was 5 years (interquartile range, 2-9 years). Most patients were male and had sustained blunt trauma (59% low-mechanism falls). Ninety-four percent of injuries were managed operatively. Most patients (79%) received intravenous opioid analgesia before their nerve block. Ropivacaine was the most common local anesthetic used (69% of blocks). No procedural complications or adverse effects were identified. CONCLUSIONS: Ultrasound-guided regional anesthesia of the femoral nerve is widely performed and can be performed safely on pediatric patients by emergency physicians and trainees in the pediatric emergency department.

Evaluating a longitudinal point-of-care-ultrasound (POCUS) curriculum for pediatric residents.

BACKGROUND: POCUS is a growing field in medical education, and an imaging modality ideal for children given the lack of ionizing radiation, ease of use, and good tolerability. A 2019 literature review revealed that no US pediatric residency programs integrated obligatory POCUS curricula. Our objective was to provide a formalized POCUS curriculum over multiple years, and to retrospectively assess improvement in resident skills and comfort. METHODS: During intern year, pediatric residents received didactics and hands-on scanning opportunities in basic POCUS applications. Their evaluation tools included pre- and post-surveys and tests, and a final performance exam. In the second and third years of residency, all participants were required to complete 8 hours per year of POCUS content review and additional hands-on training. An optional third-year curriculum was offered to interested residents as career-focused education elective time. RESULTS: Our curriculum introduced POCUS topics such as basic and advanced cardiac, lung, skin/soft tissues and procedural based ultrasound to all pediatric residents. Among first-year residents, application-specific results showed POCUS comfort level improved by 61-90%. Completed evaluations demonstrated improvement in their ability to recognize and interpret POCUS images. Second- and third-year residents reported educational effectiveness that was rated 3.9 on a 4-point Likert scale. Four third-year residents took part in the optional POCUS elective, and all reported a change in their practice with increased POCUS incorporation. CONCLUSIONS: Our longitudinal pediatric residency POCUS curriculum is feasible to integrate into residency training and exhibits early success.

Pediatric Sepsis in Community Emergency Care Settings: Guideline Concordance and Outcomes.

OBJECTIVES: Bundled pediatric sepsis care has been associated with improved outcomes in tertiary pediatric emergency departments. Sepsis care at nontertiary sites where most children seek emergency care is not well described. We sought to describe the rate of guideline-concordant care, and we hypothesized that guideline-concordant care in community pediatric emergency care settings would be associated with decreased hospital length of stay (LOS). METHOD: This retrospective cohort study of children with severe sepsis presenting to pediatric community emergency and urgent care sites included children 60 days to 17 years with severe sepsis. The primary predictor was concordance with the American College of Critical Care Medicine 2017 pediatric sepsis resuscitation bundle, including timely recognition, vascular access, intravenous fluids, antibiotics, vasoactive agents as needed. RESULTS: From January 1, 2015, to December 31, 2017, 90 patients with severe sepsis met inclusion criteria; 22 (24%) received guideline-concordant care. Children receiving concordant care had a median hospital LOS of 95.3 hours (50.9-163.8 hours), with nonconcordant care, LOS was 88.3 hours (57.3-193.2 hours). In adjusted analysis, guideline-concordant care was not associated with hospital LOS (incident rate ratio, 0.99 [0.64-1.52]). The elements that drove overall concordance were timely recognition, achieved in only half of cases, vascular access, and timely antibiotics. CONCLUSIONS: Emergency care for pediatric sepsis in the community settings studied was concordant with guidelines in only 24% of the cases. Future study is needed to evaluate additional drivers of outcomes and ways to improve sepsis care in community emergency care settings.

Ceramic water filters impregnated with silver nanoparticles as a point-of-use water-treatment intervention for HIV-positive individuals in Limpopo Province, South Africa: a pilot study of technological performance and human health benefits.

Waterborne pathogens present a significant threat to people living with the human immunodeficiency virus (PLWH). This study presents a randomized, controlled trial that evaluates whether a household-level ceramic water filter (CWF) intervention can improve drinking water quality and decrease days of diarrhea in PLWH in rural South Africa. Seventy-four participants were randomized in an intervention group with CWFs and a control group without filters. Participants in the CWF arm received CWFs impregnated with silver nanoparticles and associated safe-storage containers. Water and stool samples were collected at baseline and 12 months. Diarrhea incidence was self-reported weekly for 12 months. The average diarrhea rate in the control group was 0.064 days/week compared to 0.015 days/week in the intervention group (p < 0.001, Mann-Whitney). Median reduction of total coliform bacteria was 100% at enrollment and final collection. CWFs are an acceptable technology that can significantly improve the quality of household water and decrease days of diarrhea for PLWH in rural South Africa.

Rates and Patterns of Lower Extremity Sports Injuries in All Gender-Comparable US High School Sports.

BACKGROUND: High school athletes with lower extremity sports injuries (LESIs) frequently present to the emergency department in the United States. Previous epidemiological studies have presented rates and mechanisms of LESIs in these athletes. No studies, however, have looked at LESIs in gender-comparable sports in an attempt to evaluate what differences exist between LESIs in boys and girls. PURPOSE: To describe the epidemiology of LESIs among US high school athletes using a large national database of athletes in sports that could be considered gender comparable, given the rules of play and protective equipment. STUDY DESIGN: Descriptive epidemiology study. METHODS: Descriptive data from 2005 to 2016 were collected using the internet-based High School Reporting Information Online (High School RIO), a national high school sports injury surveillance system, for athletes participating in 8 gender-comparable sports (soccer, volleyball, basketball, baseball/softball, swimming and diving, track and field, cross-country, and tennis). Rates and patterns of injury were evaluated, with injury rates calculated as ratio of injuries per 10,000 athlete-exposures. Rate ratios (RRs) were calculated to compare the LESI rates in girls and boys. RESULTS: In both genders, LESI rates (per 10,000 athlete-exposures) were highest in soccer (girls, 15.87; boys, 11.68) followed by basketball (girls, 11.51; boys, 9.35), and were lowest in swimming and diving (girls, 0.70; boys, 0.39). Although injury rates were significantly higher in girls compared with boys in all sports, only in tennis was the RR greater than 2 (RR, 2.03; 95% CI, 1.17-3.54). Girls had a greater proportion of severe LESIs and injuries that received radiographic evaluation, such as magnetic resonance imaging, compared with boys for all sports except volleyball. Consistency in the mechanism of injury was demonstrated between genders within each sport. CONCLUSION: This study demonstrated that LESIs are common among high school athletes and disproportionately affect girls more than boys, especially when looking at severe injuries and resource utilization. Further studies are needed to elucidate the cause of these findings. We hope that the awareness of gender-based differences in LESIs will lead to improvements in targeted efforts to decrease injury rates and injury severity.

Intimate partner violence: a predictor of worse HIV outcomes and engagement in care.

For HIV-infected patients, experiencing multiple traumas is associated with AIDS-related and all-cause mortality, increased opportunistic infections, progression to AIDS, and decreased adherence to therapy. The impact of intimate partner violence (IPV) on adherence and HIV outcomes is unknown. HIV-infected patients recruited from a public HIV clinic participated in this observational cohort study (n=251). Participants completed interviews evaluating IPV and covariates. CD4 count <200 (CD4<200), detectable HIV viral load (VL), and engagement in care ("no show rate" [NSR]) were the outcomes of interest. Medication adherence was not measured. Univariate and multivariate regression analyses were performed with covariates included if p<0.3 in the univariate phase. Seventy-four percent of the participants were male, 55% Caucasian, and 52.2% self-identified as "men who have sex with men." IPV prevalence was 33.1% with no difference by gender or sexual orientation. In univariate analysis, IPV exposure predicted having a CD4<200 (p=0.005) and a detectable VL (p=0.04) but trended toward significance with a high NSR (p=0.077). Being threatened by a partner was associated with a CD4<200 (p=0.005), a detectable VL (p=0.011), and high NSR (p=0.019) in univariate analysis. In multivariate analysis, IPV predicted having a CD4<200 (p=0.005) and detectable VL (p=0.035). Being threatened by a partner predicted having a CD4<200 (p=0.020), a detectable VL (p=0.007), and a high NSR (p=0.020). Our results suggest IPV impacts biologic outcomes and engagement in care for HIV-infected patients. IPV alone predicts worse biologic outcomes, whereas the specific experience of being threatened by a partner was associated with all three outcomes in univariate and multivariate analyses.
