RESUMO

BACKGROUND: This study aimed to develop a novel clinical approach to predict intensive care unit (ICU) admission and mortality among coronavirus disease 2019 (COVID-19) patients in the emergency department (ED). METHODS: A retrospective cohort study was conducted including adults ≥ 18 years diagnosed with COVID-19 in the emergency department and admitted to the ICU between March and July 2020 in an academic hospital. The outcome variables were mortality and ICU admission. Additional variables that were collected included sex, age, comorbidities, symptom phenotype, and laboratory (lymphopenia) and imaging findings. A logistic regression model was used to construct and validate the risk models. RESULTS: A total of 808 patients were included in the study; 61.9% were men. The mean age was 57.8 ± 15.9 years, and high blood pressure (HBP) was the most prevalent comorbidity (31.8%). Seventy-six (9.4%) patients were admitted to the ICU. Age ≥ 60 years, chronic obstructive pulmonary disease (COPD), lymphopenia, and imaging findings correlated with mortality. Age ≥ 60 years, lymphopenia (<1,000 cells per microliter), and hypothyroidism correlated with ICU admission. These variables were incorporated into a scoring system (Comorbidities, Radiographic findings, Age, and Lymphopenia (CORAL) tool) to predict mortality and ICU admission. CONCLUSIONS: Our Comorbidities, Radiographic findings, Age, and Lymphopenia (CORAL) tool is a practical tool for different clinical settings independent of access to advanced medical resources or technologies. CORAL is suitable for emergency physicians in low- and middle-income countries.

RESUMO

OBJECTIVE: The specialty of emergency medicine and recognition of the need for emergency care continue to grow globally. The specialty and emergency care systems vary according to context. This study characterizes the specialty of emergency medicine around the world, trends according to region and income level, and challenges for the specialty. METHODS: We distributed a 56-question electronic survey to all members of the American College of Emergency Physicians International Ambassador Program between March 2019 and January 2020. The Ambassador Program leadership designed the survey covering specialty recognition, workforce, system components, and emergency medicine training. We analyzed results by country and in aggregate using SAS software (SAS Institute Inc). We tested the associations between World Bank income group and number of emergency medicine residency-trained physicians (RTPs) and emergency medicine specialty recognition using non-parametric Fisher's exact testing. We performed inductive coding of qualitative data for themes. RESULTS: Sixty-three out of 78 countries' teams (80%) responded to the survey. Response countries represented roughly 67% of the world's population and included countries in all World Bank income groups. Fifty-four countries (86%) recognized emergency medicine as a specialty. Ten (16%) had no emergency medicine residency programs, and 19 (30%) had only one. Eight (11%) reported having no emergency medicine RTPs and 30 (48%) had <100. Fifty-seven (90%) had an emergency medical services (EMS) system, and 52 (83%) had an emergency access number. Higher country income was associated with a higher number of emergency medicine RTPs per capita (P = 0.02). Only 6 countries (8%) had >5 emergency medicine RTPs per 100,000 population, all high income. All 5 low-income countries in the sample had <2 emergency medicine RTPs per 100,000 population. Challenges in emergency medicine development included lack of resources (38%), burnout and poor working conditions (31%), and low salaries (23%). CONCLUSIONS: Most surveyed countries recognized emergency medicine as a specialty. However, numbers of emergency medicine RTPs were small, particularly in lower income countries. Most surveyed countries reported an EMS system and emergency access number. Lack of resources, burnout, and poor pay were major threats to emergency medicine growth.

RESUMO

Background: Emergency care is an essential part of a health system. Ecuador has recognized emergency medicine as a specialty and has two emergency medicine residency training programs. However, little has been published about emergency department characteristics and capabilities in Ecuador. Objective: We described the characteristics and capabilities of emergency departments (EDs) in Quito, Ecuador, in 2017, using the National Emergency Department Inventory (NEDI) survey. Methods: The 23-item survey included questions pertaining to ED characteristics, including: visit volume, physical and administrative structure, clinical capabilities, technological resources, and consult personnel availability. This study included all EDs in Quito operating 24 hours/day, 7 days/week, and serving all patients seeking care. One representative from each ED was asked to complete the survey based on calendar year 2017. Findings: Thirty EDs met the inclusion criteria, and 26 completed the survey (87% response). The median number of ED beds was 17 (range 2-61). Median annual visit volume was 22,580 (range 1,680 to 129,676). All but two EDs provided care for both children and adults. Cardiac monitors were available in 88% of EDs, CT scanners in 68%, and rooms for respiratory isolation in 31%. Most EDs could manage patients with general medicine (92%), general surgery (92%), and gynecology (88%) emergencies 24/7. Fewer were able to provide hand surgery (45%) and dental (28%) care 24/7. Typical length of stay was 1-6 hours in 65% and >6 hours in 31% of EDs. Half of EDs reported operating at full capacity and 27% reported operating over their capacity. When compared to private EDs, government EDs (public and social security) had a higher mean number of visits per year (50,090 government vs. 13,968 private, p < 0.001), higher mean number of ED beds (36 government vs. 9 private, p = 0.002), and higher length of stay (58% of patient stays > 6 hours in government EDs vs. 86% of patient stays 1-6 hours in private EDs, p = 0.009). Conclusions: EDs in Quito varied widely with respect to annual visit volume, ability to treat different pathologies 24/7, and resources. Most EDs are functioning at or over capacity, and a substantial number have long lengths of stay. Further research and investment in emergency care could help increase the capacity and efficiency of EDs in Ecuador.

RESUMO

INTRODUCTION: Emergency medicine (EM) was recognized as a specialty in Ecuador in 1993. Currently, there are two four-year EM residency programs and an estimated 300 residency-trained emergency physicians countrywide. This study describes the current challenges in EM in Ecuador. METHODS: We conducted 25 semi-structured, in-person interviews with residency-trained emergency physicians, general practitioners, public health specialists, prehospital personnel, and physicians from other specialties. The interviewer asked about challenges in the areas of emergency care, working conditions of emergency physicians, EM residency education, EM leadership, and prehospital care. We analyzed data for challenges and registered the number of interviewees who mentioned each challenge. RESULTS: Interviewees worked in the three largest cities in the country: Quito (60%); Guayaquil (20%); and Cuenca (20%). Interviewees included 16 (64%) residency-trained emergency physicians; six (24%) residency-trained physicians from other specialties working in or closely associated with the emergency department (ED); one (4%) general practitioner working in the ED; one (4%) specialist in disasters; and one (4%) paramedic. Shortage of medical supplies, need for better medico-legal protection, lack of EM residencies outside of Quito, and desire for more bedside teaching were the challenges mentioned with the highest frequency (each 44%). The next most frequently mentioned challenges (each 38%) were the need for better access to ultrasound equipment and the low presence of EM outside the capital city. Other challenges mentioned included the low demand for emergency physicians in private institutions, the lack of differential pay for night and weekends, need for more training in administration and leadership, need for a more effective EM national society, and lack of resources and experience in EM research. CONCLUSION: Emergency medicine has a three-decade history in Ecuador, reaching important milestones such as the establishment of two EM residencies and a national EM society. Challenges remain in medical care, working conditions, residency education, leadership, and prehospital care. Stronger collaboration and advocacy among emergency physicians can help strengthen the specialty and improve emergency care.

RESUMO

PURPOSE: Smartphone technology offers a multitude of applications (apps) that provide a wide range of functions for healthcare professionals. Medical trainees are early adopters of this technology, but how they use smartphones in clinical care remains unclear. Our objective was to further characterize smartphone use by medical trainees at two United States academic institutions, as well as their prior training in the clinical use of smartphones. METHODS: In 2014, we surveyed 347 internal medicine and emergency medicine resident physicians at the University of Utah and Brigham and Women's Hospital about their smartphone use and prior training experiences. Scores (0%-100%) were calculated to assess the frequency of their use of general features (email, text) and patient-specific apps, and the results were compared according to resident level and program using the Mann-Whitney U-test. RESULTS: A total of 184 residents responded (response rate, 53.0%). The average score for using general features, 14.4/20 (72.2%) was significantly higher than the average score for using patient-specific features and apps, 14.1/44 (33.0%, P<0.001). The average scores for the use of general features, were significantly higher for year 3-4 residents, 15.0/20 (75.1%) than year 1-2 residents, 14.1/20 (70.5%, P=0.035), and for internal medicine residents, 14.9/20 (74.6%) in comparison to emergency medicine residents, 12.9/20 (64.3%, P= 0.001). The average score reflecting the use of patient-specific apps was significantly higher for year 3-4 residents, 16.1/44 (36.5%) than for year 1-2 residents, 13.7/44 (31.1%; P=0.044). Only 21.7% of respondents had received prior training in clinical smartphone use. CONCLUSION: Residents used smartphones for general features more frequently than for patient-specific features, but patient-specific use increased with training. Few residents have received prior training in the clinical use of smartphones.

RESUMO

Phosphoroselenoate RNA (PSe-RNA) is nuclease resistant and has great potentials in X-ray crystal structure and function studies of noncoding RNAs and protein-RNA interactions. In order to conveniently synthesize PSe-RNA via transcription, we have developed a one-pot synthetic method for the nucleoside 5'-(α-P-seleno)-triphosphates (NTPαSe) analogs without protecting any functionality of the ribonucleosides. The NTPαSe diastereomers have been purified, fully characterized, and incorporated into RNAs by T7 RNA polymerase. The transcribed RNAs are diastereomerically pure, and the Se-derivatized ribozymes are generally active. Furthermore, we have established an affinity purification strategy by using immobilized boronate to conveniently purify NTPαSe analogs. Though the affinity-purified NTPαSe analogs are diastereomeric mixtures, they can be directly used in transcription without a significant impact on the transcription efficiency. Moreover, we found that the PSe-nucleotide is stable during polyacrylamide gel purification, indicating that the PSe-RNAs can be purified straightforwardly for crystal structural and functional studies.
