Tracking Staff Mood and Concerns in a Pediatric Emergency Department During the COVID-19 Pandemic.

INTRODUCTION: Few studies have monitored health care worker mood and job satisfaction changes longitudinally throughout an epidemic. The objective of this study was to track staff mood, job satisfaction, questions, and suggestions in a pediatric emergency department over 1 year during the coronavirus disease 2019 pandemic. We hypothesized that staff would experience heightened negative emotions earlier in the pandemic due to uncertainty around hospital protocols and the coronavirus disease 2019 disease process. METHODS: A voluntary, cross sectional descriptive study using an anonymous electronic survey assessed job satisfaction and mood over 4 domains (sad-happy, angry-peaceful, exhausted-energized, fearful-confident) in pediatric emergency department staff members. Responses were reported with Likert scales and free-text fields. RESULTS: Of 272 survey responses, most were from nurses and clinical technicians (N = 173, 63.6%), followed by physicians and physician assistants (N = 55, 20.2%) and nonmedical staff (N = 44, 16.2%). Department-wide values for the fearful-confident and angry-peaceful domains increased over time (P = .001 and P = .01, respectively), indicating an overall more confident and peaceful mood in department staff. Job satisfaction did not change over time or by staff role. Nurses and clinical technicians reported the most exhaustion (P = .002), and physicians and physician assistants reported the most fear (P = .03). We received a total of 71 comments, which we grouped into 4 themes: protocols and procedures, personnel, infection risk, and miscellaneous. Comments submitted early in the pandemic centered around intradepartmental protocols and procedures, with a peak in staffing comments 5 months into the pandemic. DISCUSSION: An electronic survey monitoring mood, job satisfaction, and concerns in a pediatric emergency department identified mood changes in staff over the course of the coronavirus disease 2019 pandemic.

Incidence and Geographic Distribution of Injuries Due to Falls Among Pediatric Communities of Maryland.

OBJECTIVES: Falls are the leading cause of pediatric injury and account for the majority of emergency department injury visits, costing US $5 billion in medical costs annually. Epidemiology of pediatric falls has primarily been studied at single hospital centers and has not been analyzed statewide. We assessed pediatric falls across Maryland and geographically mapped them by census tract and block group. METHODS: The study used Maryland Health Services Cost Review Commission discharge data to retrospectively analyze the demographics and cross-sectional incidence rates of fall injuries in Maryland from 2013 to 2015. Geographical clusters were calculated for pediatric falls in Maryland and Baltimore City. RESULTS: From 2013 to 2015, Maryland hospitals discharged 738,819 pediatric patients, of whom 77,113 had fall injuries. Falls were more prevalent among males (56%), white race (55%), and patients with public insurance (56%). Over this period, 2 children who presented with fall injuries died. The incidence of falls did not vary from 2013 (27,481 children) to 2014 (27,261) and 2015 (26,451). Mapping fall injuries across Maryland identified Baltimore City as the primary cluster and rural pockets as secondary clusters of high incidence rates. Baltimore City maps showed a stable high-incidence cluster in the southwest region across all 3 years. CONCLUSIONS: Pediatric fall injuries comprise a large volume of emergency department visits yet have a low mortality. Geographic mapping shows that fall incidence varies across the state and persists over time. Statewide geographic information can be used to focus resource management and target prevention strategies.

An objective measure of signal quality for pediatric lung auscultations.

A stethoscope is a ubiquitous tool used to 'listen' to sounds from the chest in order to assess lung and heart conditions. With advances in health technologies including digital devices and new wearable sensors, access to these sounds is becoming easier and abundant; yet proper measures of signal quality do not exist. In this work, we develop an objective quality metric of lung sounds based on low-level and high-level features in order to independently assess the integrity of the signal in presence of interference from ambient sounds and other distortions. The proposed metric outlines a mapping of auscultation signals onto rich low-level features extracted directly from the signal which capture spectral and temporal characteristics of the signal. Complementing these signal-derived attributes, we propose high-level learnt embedding features extracted from a generative auto-encoder trained to map auscultation signals onto a representative space that best captures the inherent statistics of lung sounds. Integrating both low-level (signal-derived) and high-level (embedding) features yields a robust correlation of 0.85 to infer the signal-to-noise ratio of recordings with varying quality levels. The method is validated on a large dataset of lung auscultation recorded in various clinical settings with controlled varying degrees of noise interference. The proposed metric is also validated against opinions of expert physicians in a blind listening test to further corroborate the efficacy of this method for quality assessment.

Validation of Auscultation Technologies using Objective and Clinical Comparisons.

Technology is rapidly changing the health care industry. As new systems and devices are developed, validating their effectiveness in practice is not trivial, yet it is essential for assessing their technical and clinical capabilities. Digital auscultations are new technologies that are changing the landscape of diagnosis of lung and heart sounds and revamping the centuries old original design of the stethoscope. Here, we propose a methodology to validate a newly developed digital stethoscope, and compare its effectiveness against a market-accepted device, using a combination of signal properties and clinical assessments. Data from 100 pediatric patients is collected using both devices side by side in two clinical sites. Using the proposed methodology, we objectively compare the technical performance of the two devices, and identify clinical situations where performance of the two devices differs. The proposed methodology offers a general approach to verify a new digital auscultation device as clinically-viable; while highlighting the important consideration for clinical conditions in performing these evaluations.

Overcoming COVID-19: What can human factors and ergonomics offer?

A novel coronavirus disease, named coronavirus disease 2019 or COVID-19, which sparked an outbreak in Wuhan, China in December 2019, is now a pandemic. The rapid spread of this disease from one to more than 155 regions worldwide in 2.5 months highlights the need for better preparation to manage a pandemic. In this commentary, we describe how Human Factors and Ergonomics (HFE) can contribute to the COVID-19 pandemic response. Specifically, we provide an example of how HFE methodologies informed workflow redesigns implemented as part of COVID-19 pandemic preparations in an academic pediatric ambulatory clinic. We then identify key mechanisms and areas where HFE can contribute to and improve the effectiveness of a pandemic response: Just-in-time (JIT) training development, adapting workflows and processes, restructuring teams and tasks, developing effective mechanisms and tools for communication, engaging patient and families to follow the recommended practices (e.g., social distancing, revised hospital visitation policies), identifying and mitigating barriers to implementation of plans, and learning from failures and successes to improve both the current and future pandemic responses. We recommend integrating HFE approaches and tools across health care systems, state health organizations, and the Centers for Disease Control and Prevention (CDC) as they confront this pandemic.

Perspectives on the Management of Children in a Biocontainment Unit: Report of the NETEC Pediatric Workgroup.

During the outbreak of Ebola virus disease that struck West Africa during 2014-2016, a small handful of expatriate patients were evacuated to specialized high-level containment care units, or biocontainment units, in the United States and Western Europe. Given the lower mortality rate (18% versus 40% for those treated in Africa) among these patients, it is likely that high-level containment care will be used in the future with increasing frequency. It is also likely that children infected with Ebola and other highly hazardous communicable diseases will someday require such care. The National Ebola Training and Education Center convened a pediatric workgroup to consider the unique and problematic issues posed by these potential child patients. We report here the results of those discussions.

The Mortality of Ill Infants with False Tooth Extraction in a Rural Ugandan Emergency Department.

False tooth extraction (FTE), a cultural practice in East Africa used to treat fever and diarrhea in infants, has been thought to increase infant mortality. The mortality of clinically similar infants with and without false tooth extraction has not previously been examined. The objective of our retrospective cohort study was to examine the mortality, clinical presentation, and treatment of infants with and without false tooth extraction. We conducted a retrospective chart review of records of infants with diarrhea, sepsis, dehydration, and fever in a rural Ugandan emergency department. Univariate analysis was used to test statistical significance. We found the mortality of infants with false tooth extraction (FTE+) was 18% and without false tooth extraction (FTE-) was 14% (P=0.22). The FTE+ study group, and FTE- comparison group, had similar proportions of infants with abnormal heart rate and with hypoxia. There was a significant difference in the portion of infants that received antibiotics (P=0.001), and fluid bolus (P=0.002). Although FTE+ infants had clinically similar ED presentations to FTE- infants, the FTE+ infants were significantly more likely to receive emergency department interventions, and had a higher mortality than FTE- infants.

Analysis of CUL-5 expression in breast epithelial cells, breast cancer cell lines, normal tissues and tumor tissues.

BACKGROUND: The chromosomal location of CUL-5 (11q 22-23) is associated with LOH in breast cancer, suggesting that CUL-5 may be a tumor suppressor. The purpose of this research was to determine if there is differential expression of CUL-5 in breast epithelial cells versus breast cancer cell lines, and normal human tissues versus human tumors. The expression of CUL-5 in breast epithelial cells (HMEC, MCF-10A), and breast cancer cells (MCF-7, MDA-MB-231) was examined using RT-PCR, Northern blot analysis, and Western blot analysis. The expression of mRNA for other CUL family members (CUL-1, -2, -3, -4A, and -4B) in these cells was evaluated by RT-PCR. A normal human tissue expression array and a cancer profiling array were used to examine CUL-5 expression in normal human tissues and matched normal tissues versus tumor tissues, respectively. RESULTS: CUL-5 is expressed at the mRNA and protein levels by breast epithelial cells (HMEC, MCF-10A) and breast cancer cells (MCF-7, MDA-MB-231). These cells also express mRNA for other CUL family members. The normal human tissue expression array revealed that CUL-5 is widely expressed. The cancer profiling array revealed that 82% (41/50) of the breast cancers demonstrated a decrease in CUL-5 expression versus the matched normal tissue. For the 50 cases of matched breast tissue there was a statistically significant approximately 2.2 fold decreased expression of CUL-5 in tumor tissue versus normal tissue (P < 0.0001). CONCLUSIONS: The data demonstrate no apparent decrease in CUL-5 expression in the breast cancer cell lines (MCF-7, MDA-MB-231) versus the breast epithelial cells (HMEC, MCF-10A). The decrease in CUL-5 expression in breast tumor tissue versus matched normal tissue supports the hypothesis that decreased expression of CUL-5 may play a role in breast tumorigenesis.
