Impact of the COVID-19 Pandemic on Emergency Department Encounters in a Major Metropolitan Area.

BACKGROUND: The end of 2019 marked the emergence of the COVID-19 pandemic. Public avoidance of health care facilities, including the emergency department (ED), has been noted during prior pandemics. OBJECTIVE: This study described pandemic-related changes in adult and pediatric ED presentations, acuity, and hospitalization rates during the pandemic in a major metropolitan area. METHODS: The study was a cross-sectional analysis of ED visits occurring before and during the pandemic. Sites collected daily ED patient census; monthly ED patient acuity, as the Emergency Severity Index (ESI) score; and disposition. Prepandemic ED visits occurring from January 1, 2019 through December 31, 2019 were compared with ED visits occurring during the pandemic from January 1, 2020 through March 31, 2021. The change in prepandemic and pandemic ED volume was found using 7-day moving average of proportions. RESULTS: The study enrolled 83.8% of the total ED encounters. Pandemic adult and pediatric visit volume decreased to as low as 44.7% (95% CI 43.1-46.3%; p < 0.001) and 22.1% (95% CI 19.3-26.0%; p < 0.001), respectively, of prepandemic volumes. There was also a relative increase in adult and pediatric acuity (ESI level 1-3) and the admission percentage for adult (20.3% vs. 22.9%; p < 0.01) and pediatric (5.1% vs. 5.6%; p < 0.01) populations. CONCLUSIONS: Total adult and pediatric encounters were reduced significantly across a major metropolitan area. Patient acuity and hospitalization rates were relatively increased. The development of strategies for predicting ED avoidance will be important in future pandemics.

Haboob Dust Storms and Motor Vehicle Collision-related Trauma in Phoenix, Arizona.

BACKGROUND: The Sonoran Desert region, encompassing most of southern Arizona, has an extreme climate that is famous for dust storms known as haboobs. These storms lead to decreased visibility and potentially hazardous driving conditions. In this study we evaluate the relationship between haboob events and emergency department (ED) visits due to motor vehicle collisions (MVCs) in Phoenix, Arizona. METHODS: This study is a retrospective analysis of MVC-related trauma presentations to Phoenix, AZ, hospitals before and following haboob dust storms. These events were identified from 2009-2017 primarily using Phoenix International Airport weather data. De-identified trauma data were obtained from the Arizona Department of Health Services (ADHS) Arizona State Trauma Registry (ASTR) from seven trauma centers within a 10-mile radius of the airport. We compared MVC-related trauma using six- and 24-hour windows before and following the onset of haboob events. RESULTS: There were 31,133 MVC-related trauma encounters included from 2009-2017 and 111 haboob events meeting meteorological criteria during that period. There was a 17% decrease in MVC-related ED encounters in the six hours following haboob onset compared to before onset (235 vs 283, P = 0.04), with proportionally more injuries among males (P < 0.001) and higher mortality (P = 0.02). There was no difference in frequency of presentations (P = 0.82), demographics, or outcomes among the 24-hour pre-and post-haboob groups. CONCLUSION: Haboob dust storms in Phoenix, Arizona, are associated with a decrease in MVC-related injuries during the six-hour period following storm onset, likely indicating the success of public safety messaging efforts. Males made up a higher proportion of those injured during the storms, suggesting a target for future interventions. Future public-targeted weather-safety initiatives should be accompanied more closely by monitoring and evaluation efforts to assess for effectiveness.

Analgesia use in trauma patients at a university teaching hospital in Kigali, Rwanda.

Introduction: While trends in analgesia have been identified in high-income countries, little research exists regarding analgesia administration in low- and middle-income countries (LMIC). This study evaluates analgesia administration and clinical characteristics among patients seeking emergency injury care at University Teaching Hospital-Kigali in Kigali, Rwanda. Methods: This retrospective, cross-sectional study utilized a random sample of emergency center (EC) cases accrued between July 2015 and June 2016. Data was extracted from the medical record for patients who had an injury and were ≥ 15 years of age. Injury-related EC visits were identified by presenting complaint or final discharge diagnosis. Sociodemographic information, injury mechanism and type, and analgesic medications ordered and administered were analyzed. Results: Of the 3,609 random cases, 1,329 met eligibility and were analyzed. The study population was predominantly male (72%) with a median age of 32 years and range between 15 and 81 years. In the studied sample, 728 (54.8%) were treated with analgesia in the EC. In unadjusted logistic regression, only age was not a significant predictor of receiving pain medication and was excluded from the adjusted analysis. In the adjusted model, all predictors remained significant, with being male, having at least one severe injury, and road traffic accident (RTA) as injury mechanism being significant predictors of analgesia administration. Conclusion: In the study setting of injured patients in Rwanda, being male, involved in RTA or having more than one serious injury was associated with higher odds of receiving pain medication. Approximately half of the patients with traumatic injuries received pain medications, predominantly opioids with no factors predicting whether a patient would receive opioids versus other medications. Further research on implementation of pain guidelines and drug shortages is warranted to improve pain management for injured patients in the LMIC setting.

Chest trauma epidemiology and emergency department management in a tertiary teaching hospital in Kigali, Rwanda.

Introduction: Chest trauma is a major contributor to injury morbidity and mortality, and understanding trends is a crucial part of addressing this burden in low- and middle-income countries. This study reports the characteristics and emergency department (ED) management of chest trauma patients presenting to Rwanda's national teaching hospital in Kigali. Methods: This descriptive analysis included a convenience sample of patients presenting to a single tertiary hospital ED with chest trauma from June to December 2017. Demographic data were collected as well as injury mechanism, thoracic and associated injuries, types of imaging obtained, and treatments performed. Chart review was conducted seven days post-admission to follow up on outcomes and additional diagnoses and interventions. Incidences were calculated with Microsoft Excel. Results: Among the 62 patients included in this study, 74% were male, and mean age was 35 years. Most patients were injured in road traffic crashes (RTCs) (68%). Common chest injuries included lung contusions (79% of cases), rib fractures (44%), and pneumothoraces (37%). Head trauma was a frequent concurrent extra-thoracic injury (61%). Diagnostic imaging primarily included E-FAST ultrasound (92%) and chest x-ray (98%). The most common therapies included painkillers (100%), intravenous fluids (89%), and non-invasive oxygen (63%), while 29% underwent invasive intervention in the form of thoracostomy. The majority of patients were admitted (81%). Pneumonia was the most common complication to occur in the first seven days (32% of admitted patients). Ultimately, 40% of patients were discharged home within seven days of presentation, 50% remained hospitalized, and 5% died. Conclusion: This study on the epidemiology of chest trauma in Rwanda can guide injury prevention and medical training priorities. Efforts should target prevention in young males and those involved in RTCs. ED physicians in Rwanda need to be prepared to diagnose and treat a variety of chest injuries with invasive and noninvasive means.

Seasonal influence of tuberculosis diagnosis in Rwanda.

BACKGROUND: Tuberculosis (TB) remains a major global health concern. Previous research reveals that TB may have a seasonal peak during the spring and summer seasons in temperate climates; however, few studies have been conducted in tropical climates. This study evaluates the influence of seasonality on laboratory-confirmed TB diagnosis in Rwanda, a tropical country with two rainy and two dry seasons. METHODS: A retrospective chart review was performed at the University Teaching Hospital-Kigali (CHUK). From January 2016 to December 2017, 2717 CHUK patients with TB laboratory data were included. Data abstracted included patient demographics, season, HIV status, and TB laboratory results (microscopy, GeneXpert, culture). Univariate and multivariable logistic regression (adjusted for age, gender, and HIV status) analyses were performed to assess the association between season and laboratory-confirmed TB diagnoses. RESULTS: Patients presenting during rainy season periods had a lower odds of laboratory-confirmed TB diagnosis compared to the dry season (aOR=0.78, 95% CI 0.63-0.97, p=0.026) when controlling for age group, gender, and HIV status. Males, adults, and people living with HIV were more likely to have laboratory-confirmed TB diagnosis. On average, more people were tested for TB during the rainy season per month compared to the dry season (120.3 vs. 103.3), although this difference was not statistically significant. CONCLUSION: In Rwanda, laboratory-confirmed TB case detection shows a seasonal variation with patients having higher odds of TB diagnosis occurring in the dry season. Further research is required to further elucidate this relationship and to delineate the mechanism of season influence on TB diagnosis.

Parental Notification Via Text Messaging for Infant Sickle Screening Programs: Exploration of Feasibility and Acceptability in Uganda.

Sickle cell disease (SCD) in Africa has high prevalence, morbidity, and early mortality. Difficulties in reaching parents following infant SCD screening dampen program effectiveness. Text messaging may support initial postscreening parental notification. We explored SCD awareness, and feasibility and acceptability of text messaging about screening follow-up among convenience samples of caretakers with children under 5 years (n=115) at 3 sites: a SCD family conference or 2 general pediatric clinics in urban or rural Uganda. Two thirds of the conference-based participants and 8% at clinic sites had affected children. At the clinics, 64% of caretakers were aware of SCD. In all, 87% claimed current possession of mobile phones; 89% previously had received messages. A sample text on the availability of screening results and need to bring their child to SCD clinic was at least partially understood by 82%. Overall, 52% preferred communication for initial follow-up by telephone over text message. Concerns about texting included phone access, privacy or cost, and readability of messages. Caretakers identified concerns about distance, cost, or preference for another clinic as additional barriers to SCD follow-up. Findings suggest that text messaging to caretakers may be feasible, but less acceptable compared with a telephone call about initial follow-up from newborn SCD screening.

Depressive symptoms, sexual activity, and substance use among adolescents in Kampala, Uganda.

BACKGROUND: Adolescents experience high rates of depression, initiation of sexual activity, and substance use. OBJECTIVES: To better understand the demographics of adolescents presenting to an adolescent clinic in Uganda, and to elucidate which factors are associated with depressive symptoms, sexual initiation, and substance use. METHODS: A retrospective review was performed on intake forms obtained during interviews with adolescents presenting to the Makerere/Mulago Columbia Adolescent Health Clinic (MMCAH) in Kampala, Uganda. RESULTS: Depressive symptoms in adolescents were correlated with having a chronic illness (p=.026), and reported poor quality of home life (p<.001). Initiation of sexual activity was also correlated with chronic illness (p=.008) and poor quality of home life (p=.006). Substance use was correlated with maternal death (p=.041), chronic illness (p=.038), and substance use among family members (p<.001) and friends (p<.001). CONCLUSIONS: Knowing the aforementioned risk factors can help us better understand the needs of adolescents presenting to MMCAH, and allows us to develop targeted interventions aimed at decreasing health risks in Kampala's adolescent population.

Impact of ultrasound on management for dyspnea presentations in a Rwandan emergency department.

BACKGROUND: The complexity of diagnosis for critically ill dyspnea presentations in the emergency department remains a challenge. Accurate and rapid recognition of associated life-threatening conditions is paramount for timely treatment. Point-of-care ultrasound (POCUS) has been shown to impact the diagnosis of dyspnea presentations in resource-rich settings, and may be of greater diagnostic benefit in resource-limited settings. METHODS: We prospectively enrolled a convenience sample of 100 patients presenting with dyspnea in the Emergency Department at University Teaching Hospital of Kigali (UTH-K) in Rwanda. After a traditional history and physical exam, the primary treating team listed their 3 main diagnoses and ranked their confidence accuracy in the leading diagnosis on a Likert scale (1-5). Multi-organ ultrasound scans performed by a separate physician sonographer assessed the heart, lungs, inferior vena cava, and evaluated for lower extremity deep vein thrombosis or features of disseminated tuberculosis. The sonographer reviewed the findings with the treating team, who then listed 3 diagnoses post-ultrasound and ranked their confidence accuracy in the leading diagnosis on a Likert scale (1-5). The hospital diagnosis at discharge was used as the standard in determining the accuracy of the pre- and post-ultrasound diagnoses. RESULTS: Of the 99 patients included in analysis, 57.6% (n = 57) were male, with a mean age of 45 years. Most of them had high-level acuity (54.5%), the dyspnea was of acute onset (45.5%) and they came from district hospitals (50.5%). The most frequent discharge diagnoses were acute decompensated heart failure (ADHF) (26.3%) and pneumonia (21.2%). Ultrasound changed the leading diagnosis in 66% of cases. The diagnostic accuracy for ADHF increased from 53.8 to 100% (p = 0.0004), from 38 to 85.7% for pneumonia (p = 0.0015), from 14.2 to 85.7% for extrapulmonary tuberculosis (p = 0.0075), respectively, pre and post-ultrasound. The overall physician diagnostic accuracy increased from 34.7 to 88.8% pre and post- ultrasound. The clinician confidence in the leading diagnosis changed from a mean of 3.5 to a mean of 4.7 (Likert scale 0-5) (p < 0.001). CONCLUSIONS: In dyspneic patients presenting to this Emergency Department, ultrasound frequently changed the leading diagnosis, significantly increased clinicians' confidence in the leading diagnoses, and improved diagnostic accuracy.
