Impact of Povidone-iodine Versus Chlorhexidine for Periurethral Cleaning Before Catheterization on Pyuria and Bacteriuria Among Emergency Department Patients

Background: We aimed to determine the effect of periurethral cleaning before catheterization using chlorhexidine and povidone-iodine on bacteriuria and pyuria. Methods: This study was a single-blind clinical trial on a sample selected by convenience sampling. Demographic and clinical questionnaires were completed, and patients were randomly divided into two groups) 36 patients each of povidone-iodine and chlorhexidine using Minimization Software based on confounding variables including age, consciousness level, triage level, nutritional status, and underlying disease. The periurethral areas were cleaned with the given antiseptics and catheterized using standard and sterile procedures. Then, specimens were taken for urinalysis and urine culture immediately, 72 hours, and five days after catheterization. Then, bacteriuria rate, pyuria rate, and the number of microorganisms were determined through examinations. Data analysis was conducted using SPSS version 19. Results: There was no statistically significant difference in the bacteriuria rate between the two groups immediately (P = 0.76), 72 hours (P = 0.22), and five days (P = 0.50) after catheterization. The positive pyuria rate was not significantly different between the two groups immediately after catheterization. However, it was significantly higher in the povidone-iodine group 72 hours (P = 0.03) and five days (P = 0.004) after catheterization. The Mann-Whitney test compared the mean number of microorganisms between the two groups at different times. This test showed no significant difference in the number of microorganisms immediately (P = 0.93), 72 hours (P = 0.43), and five days (P = 0.61) after catheterization. Conclusions: Due to the lower side effects of chlorhexidine than povidone-iodine, it is suggested that similar studies be performed in other hospital wards with more stable patients to obtain more statistically significant results.

Analysis of Factors Affecting the Length of Stay in the Emergency Department for Critically Ill Patients Transferred to Regional Emergency Medical Centers

BackgroundTransferring an emergency patient to another emergency department (ED) is necessary when she/he is unable to receive necessary treatment from the first visited ED, although the transfer poses potential risks for adverse clinical outcomes and lowering the quality of emergency medical services by overcrowding the transferred ED. This study aimed to understand the factors affecting the ED length of stay (LOS) of critically ill patients and to investigate whether they are receiving prompt treatment through Interhospital Transfer (IHT).MethodsThis study analyzed 968 critically ill patients transferred to the ED of the study site in 2019. Machine learning based prediction models were built to predict the ED LOS dichotomized as greater than 6 hours or less. Explanatory variables in patient characteristics, clinical characteristics, transfer-related characteristics, and ED characteristics were selected through univariate analyses.ResultsAmong the prediction models, the Logistic Regression (AUC 0.85) model showed the highest prediction performance, followed by Random Forest (AUC 0.83) and Naïve Bayes (AUC 0.83). The Logistic Regression model suggested that the need for emergency operation or angiography (OR 3.91, 95% CI=1.65–9.21), the need for Intensive Care Unit (ICU) admission (OR 3.84, 95% CI=2.53–5.83), fewer consultations (OR 3.57, 95% CI=2.84–4.49), a high triage level (OR 2.27, 95% CI=1.43–3.59), and fewer diagnoses (OR 1.32, 95% CI=1.09–1.61) coincided with a higher likelihood of 6-hour-or-less stays in the ED. Furthermore, an interhospital transfer handoff led to significantly shorter ED LOS among the patients who needed emergency operation or angiography, or ICU admission, or had a high triage level.ConclusionsThe results of this study suggest that patients prioritized in emergency treatment receive prompt intervention and leave the ED in time. Also, having a proper interhospital transfer handoff before IHT is crucial to provide efficient care and avoid unnecessarily longer stay in ED.

Pediatric triage variations among nurses, pediatric and emergency residents using the Canadian triage and acuity scale

Background Emergency care continues to be a challenge, since patients’ arrival is unscheduled and could occur at the same time which may fill the Emergency Department with non-urgent patients. Triaging is an integral part of every busy ED. The Canadian Triage and Acuity Scale (CTAS) is considered an accurate tool to be used outside Canada. This study aims to identify the chosen triage level and compare the variation between registered nurses, pediatric and adult emergency residents by using CTAS cases. Method This study was conducted at King Abdulaziz Medical City,Saudi Arabia. A cross-sectional self-administered questionnaire was used, and which contains 15 case scenarios with different triage levels. All cases were adopted from a Canadian triage course after receiving permission. Each case provides the patient’s symptoms, clinical signs and mode of arrival to the ED. The participants were instructed to assign a triage level using the following scale. A non-random sampling technique was used for this study. The rates of agreement between residents were calculated using kappa statistics (weighted-kappa) (95%CI). Result A total of 151 participants completed the study questionnaire which include 15 case scenarios. 73 were nurses and 78 were residents. The results showed 51.3, 56.6, and 59.9% mis-triaged the cases among the nurses, emergency residents, and pediatric residents respectively. Triage scores were compared using the Kruskal Wallis test and were statistically significant with a p value of 0.006. The mean ranks for nurses, emergency residents and pediatric residents were 86.41, 73.6 and 59.96, respectively. The Kruskal Wallis Post-Hoc test was performed to see which groups were statistically significant, and it was found that there was a significant difference between nurses and pediatrics residents (P value = 0.005). Moreover, there were no significant differences found between nurses and ER residents (P value> 0.05). Conclusion The triaging system was found to be a very important tool to prioritize patients based on their complaints. The results showed that nurses had the greatest experience in implementing patients on the right triage level. On the other hand, ER and pediatric residents need to develop more knowledge about CTAS and become exposed more to the triaging system during their training.

Association between triage level and outcomes at Médecins Sans Frontières trauma hospital in Kunduz, Afghanistan, 2015

BackgroundFive million people die annually due to injuries; an increasing part is due to armed conflict in low-income and middle-income countries, demanding resolute emergency trauma care. In Afghanistan, a low-income country that has experienced conflict for over 35 years, conflict related trauma is a significant public health problem. To address this, the non-governmental organisation Médecins Sans Frontières (MSF) set up a trauma centre in Kunduz (Kunduz Trauma Centre (KTC)). MSF’s standardised emergency operating procedures include the South African Triage Scale (SATS). To date, there are few studies that assess how triage levels correspond with outcome in low-resource conflict settingsAimThis study aims to assess to what extent SATS triage levels correlated to outcomes in terms of hospital admission, intensive care unit (ICU) admission and mortality for patients treated at KTC.Method and materialsThis retrospective study used routinely collected data from KTC registries. A total of 17 970 patients were included. The outcomes were hospital admission, ICU admission and mortality. The explanatory variable was triage level. Covariates including age, gender and delay to arrival were used. Logistic regression was used to study the correlation between triage level and outcomes.ResultsOut of all patients seeking care, 70% were triaged as red or orange. The overall mortality was 0.6%. In total, 90% of those that died and 79% of ICU-admitted patients were triaged as red.ConclusionThe risk of positive and negative outcomes correlated with triage level. None of the patients triaged as green died or were admitted to the ICU whereas 90% of patients who died were triaged as red.

Impact of a Disaster Drill on Waiting Times in a Pediatric Emergency Department

Objective: Emergency departments should improve their preparedness for mass casualty incidents (MCIs) through periodic drills. These exercises are conducted while maintaining regular care. The aim of this study was to determine the impact of a disaster drill in a pediatric emergency department (PED) on real patients’ waiting times. Methods: On September 10, 2019, a 4-h disaster drill was conducted in the PED of a tertiary pediatric hospital, with minimal staff reinforcement (2 nurses). Cases were real patients that came to the PED during the drill. The patients that visited the PED the day before were the control group. Variables analyzed were: age, sex, destination, triage level, time-to-triage, time-to-physician, length of PED stay, and percentage of patients visited within the optimal time according to triage level. Results: Sixty-eight patients (case group) and 63 patients (control group) were analyzed; both groups were comparable except for the median age. There were no differences in time-to-triage, time-to-physician, and length of PED stay between the 2 groups. The percentage of patients visited within optimal time according to triage level was higher in the case group. Conclusions: Conducting an MCI drill in the PED, with minimal staff reinforcement, was not detrimental to real patients’ waiting times.

An interrater reliability study on the Gothenburg obstetric triage system- a new obstetric triage system

Background Triage, identifying patients with critical and time-sensitive disorders, is an integrated process in general emergency medicine. Obstetric triage is more specialised, requiring assessment of both woman, fetus and labour status. Failure to identify severely ill obstetric patients has repeatedly led to maternal morbidity and mortality. Reliable triage systems, adapted to obstetric patients as well as local conditions, are thus essential. The study aims to assess the interrater reliability (IRR) of the Gothenburg Obstetric Triage System (GOTS). Methods Midwives (n = 6) and registered nurses with no experience in managing obstetric patients (n = 7), assessed 30 paper cases based on actual real-life cases, using the GOTS. Furthermore, a reference group consisting of two midwives and two obstetricians, with extensive experience in obstetric care, determined the correct triage level in order to enable analysis of over- and undertriage. IRR was assessed, both with percentage of absolute agreement and with intra-class correlation coefficients (ICC) with 95% confidence intervals (CI). Results A total of 388 assessments were performed, comprising all five levels of acuity in the GOTS. Absolute agreement was found in 69.6% of the assessments. The overall IRR was good, with a Kappa value of 0.78 (0.69–0.87, 95% CI) for final triage level. Comparison with reference group assessments established that over- and undertriage had occurred in 9% and 21% of the cases, respectively. The main reasons for undertriage were “not acknowledging abnormal vital sign parameters” and “limitations in study design”. Conclusion The GOTS is a reliable tool for triaging obstetric patients. It enables a standardized triage process unrelated to the assessors’ level of experience in assessing and managing obstetric patients and is applicable for triaging obstetric patients presenting for emergency care at obstetric or emergency units.

1A Nationwide Analysis of U.S. Racial/Ethnic Disparities in Emergency Department Patients with Mental Health and Substance Use Disorders

BackgroundRacial and ethnic health disparities have been linked with inequalities in access to health care and outcomes. The present study considers whether inequalities persist between racial/ethnic groups among patients with mental health or substance use disorders who visit the emergency department (ED). MethodsWe analyzed data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2012-2018, assessing health disparities among patients diagnosed with mental health or substance use disorders by observing whether significant differences exist in ED wait time and length of visit (LOV) for patients of different races/ethnicities. Stratified models were performed to further understand the impact of regions across the U.S., year, and triage level on the association analysis. ResultsFrom 2012-2018, non-Hispanic Black and Hispanic patients experienced significantly longer ED wait times and LOV as compared to White patients. Patients with private insurance experienced significantly shorter wait times compared to patients with self-pay, and shorter LOV than those with Medicaid/ Children’s Health Insurance Program, or Medicare. Male patients had significantly longer LOV compared to female patients. We observed year by year differences in wait times of non-Hispanic Black patients with improvement appearing between the years 2013 to 2016, while LOV remained consistently longer. We observed both regional and triage level differences, with the U.S. Northeast presenting with the most disparities. Additionally, we noted a general upward trend of SUD diagnoses. Conclusion Our analysis suggests that while there has been an overall improvement in median ED wait time through the years, non-Hispanic Black and Hispanic patients experience significantly longer ED wait time compared to non-Hispanic White patients. Additionally, non-Hispanic Black and Hispanic patients have a significantly longer ED LOV compared to non-Hispanic White patients.

An updated national survey of triage and triage related work in Sweden: a cross-sectional descriptive and comparative study

Background Triage and triage related work has been performed in Swedish Emergency Departments (EDs) since the mid-1990s. According to two national surveys from 2005 to 2011, triage was carried out with different triage scales and without guidelines or formal education. Furthermore, a review from 2010 questioned the scientific evidence for both triage as a method as well as the Swedish five level triage scale Medical Emergency Triage and Treatment System (METTS); nevertheless, METTS was applied in 65% of the EDs in 2011. Subsequently, METTS was renamed to Rapid Emergency Triage and Treatment System (RETTS©). The hypothesis for this study is that the method of triage is still applied nationally and that the use of METTS/RETTS© has increased. Hence, the aim is to describe the occurrence and application of triage and triage related work at Swedish Emergency Departments, in comparison with previous national surveys. Methods In this cross-sectional study with a descriptive and comparative design, an electronic questionnaire was developed, based on questionnaire from previous studies. The survey was distributed to all hospital affiliated EDs from late March to the middle of July in 2019. The data was analysed with descriptive statistics, by IBM SPSS Statistics, version 26. Results Of the 51 (75%) EDs partaking in the study, all (100%) applied triage, and 92% used the Swedish triage scale RETTS©. Even so, there was low concordance in how RETTS© was applied regarding time frames i.e., how long a patient in respective triage level could wait for assessment by a physician. Additionally, the results show a major diversion in how the EDs performed education in triage. Conclusion This study confirms that triage method is nationally implemented across Swedish EDs. RETTS© is the dominating triage scale but cannot be considered as one triage scale due to the variation with regard to time frames per triage level. Further, a diversion in introduction and education in the pivotal role of triage has been shown. This can be counteracted by national guidelines in what triage scale to use and how to perform triage education.
