RESUMO
Background: The Cardiac Arrest Registry to Enhance Survival (CARES) was created in 2004 in collaboration with the Centers for Disease Control and Prevention (CDC) and Emory University School of Medicine's Department of Emergency Medicine. The registry allows local communities to benchmark their performance, enhance the quality of care, and increase survival rates for out-of-hospital cardiac arrest (OHCA). Methods/design: CARES enrolls patients who experience a non-traumatic, EMS-treated OHCA. For each case, data is collected from three sources: 911 call center data, EMS data, and hospital data. CARES data is de-identified and stored in a secured web-based cloud platform and maintains confidentiality throughout the process. CARES data is subjected to an internal auditing system that oversees both local and regional levels. The variables in CARES adhere with the Utstein style reporting system and the National EMS Information System (NEMSIS) standard. Discussion: As of 2023, CARES captures data from a population base of over 178 million people which accounts for 53% of the total U.S. population. Over the past two decades, CARES has consistently been a part of public health surveillance for OHCA and serves as a quality improvement tool to improve cardiac arrest outcomes. Moreover, CARES commits to facilitate observational research on OHCA, continues to modernize its software platform, and comprehensively expands its coverage for the entire U.S.
RESUMO
BACKGROUND: Training on how to perform a prehospital extended focused assessment with sonography in trauma (EFAST) has resulted in improved outcomes for trauma patients in several countries. The result of previous studies showed good accuracy despite minimal training. However, data on the diagnostic accuracy among untrained paramedic students and the course length in middle-income countries is scarce. In Thailand, the current paramedic education does not include training on prehospital ultrasounds. In the present study, we aimed to investigate the diagnostic accuracy of EFAST among ultrasound-naïve paramedic students and factors that are associated with successful posttest training. METHODS: Final-year paramedic students attending a 4-year university program were included in this study. A 2-h didactic training session and 1-h hands-on workshop were led by experienced emergency physicians. The diagnostic indices for EFAST interpretation were obtained pretraining and posttraining. The participants' ultrasound image acquisition was also evaluated individually on a mannequin model using a standardized assessment tool. RESULTS: In total, 47 paramedic students were voluntarily enrolled and underwent EFAST training. Of these participants, 31 (66%) reported having >1 year of experience in the prehospital field. Four were advanced emergency medical technicians before becoming paramedic students. The sensitivity, specificity, positive predictive value, and negative predictive value after training were 85.7% (95% CI, 81.5-89.3), 81.6% (95% CI, 74.2-87.6), 91.6% (95% CI, 87.9-94.4), and 71% (95% CI, 63.3-77.8), respectively. Previous prehospital experience was not associated with accuracy. CONCLUSION: This study demonstrated that paramedic students in Thailand were able to achieve a competency comparable with that of other medical professionals in a simulated environment. The total 3 h training course was sufficient for them to acquire EFAST skills.
RESUMO
AIM: The prevalence of hypertonic dehydration (HD) among community-dwelling and hospitalized populations has been evaluated. However, to our knowledge, no study had previously focused on older patients admitted to the emergency department (ED). The present study aimed to evaluate the prevalence, risk factors and short-term outcomes of HD among Thai older patients admitted to the ED. METHODS: This was a prospective cross-sectional study at one urban ED in Thailand. Patients aged ≥65 years who were admitted to the ED were enrolled into the study. Data including clinical hydration status, Charlson Comorbidity Index (CCI) score, activities of daily living score, current use of medications, laboratory examination results and serum osmolarity level were collected. HD was defined as a serum osmolarity level of >300 mOsm/kg. The short-term outcomes were a 30-day ED revisit, hospital readmission and mortality rates. RESULTS: In total, 80 (21.6%) of 370 patients presented with HD. A CCI score of ≥5 was found associated with HD among older patients (adjusted odds ratio: 1.82; 95% confidence interval: 1.03-3.21). The ED revisit rates were 18.1% in the dehydrated group and 10.9% in the non-dehydrated group. The hospital readmission rates were 8.3% in the dehydrated group and 10.6% in the non-dehydrated group. Furthermore, the 30-day mortality rates were 6.9% and 5.3% in the dehydrated and non-dehydrated groups, respectively. CONCLUSIONS: One-fifth of older patients admitted to the ED presented with HD. A CCI score of ≥5 was considered a risk factor of HD. Moreover, further studies should focus on the long-term outcomes of HD and risk reduction. Geriatr Gerontol Int 2021; 21: 485-491.
