ABSTRACT
BACKGROUND: The availability of patient outcomes-based feedback is limited in episodic care environments such as the emergency department. Emergency medicine (EM) clinicians set care trajectories for a majority of hospitalized patients and provide definitive care to an even larger number of those discharged into the community. EM clinicians are often unaware of the short- and long-term health outcomes of patients and how their actions may have contributed. Despite large volumes of patients and data, outcomes-driven learning that targets individual clinician experiences is meager. Integrated electronic health record (EHR) systems provide opportunity, but they do not have readily available functionality intended for outcomes-based learning. OBJECTIVE: This study sought to unlock insights from routinely collected EHR data through the development of an individualizable patient outcomes feedback platform for EM clinicians. Here, we describe the iterative development of this platform, Linking Outcomes Of Patients (LOOP), under a human-centered design framework, including structured feedback obtained from its use. METHODS: This multimodal study consisting of human-centered design studios, surveys (24 physicians), interviews (11 physicians), and a LOOP application usability evaluation (12 EM physicians for ≥30 minutes each) was performed between August 2019 and February 2021. The study spanned 3 phases: (1) conceptual development under a human-centered design framework, (2) LOOP technical platform development, and (3) usability evaluation comparing pre- and post-LOOP feedback gathering practices in the EHR. RESULTS: An initial human-centered design studio and EM clinician surveys revealed common themes of disconnect between EM clinicians and their patients after the encounter. Fundamental postencounter outcomes of death (15/24, 63% respondents identified as useful), escalation of care (20/24, 83%), and return to ED (16/24, 67%) were determined high yield for demonstrating proof-of-concept in our LOOP application. The studio aided the design and development of LOOP, which integrated physicians throughout the design and content iteration. A final LOOP prototype enabled usability evaluation and iterative refinement prior to launch. Usability evaluation compared to status quo (ie, pre-LOOP) feedback gathering practices demonstrated a shift across all outcomes from "not easy" to "very easy" to obtain and from "not confident" to "very confident" in estimating outcomes after using LOOP. On a scale from 0 (unlikely) to 10 (most likely), the users were very likely (9.5) to recommend LOOP to a colleague. CONCLUSIONS: This study demonstrates the potential for human-centered design of a patient outcomes-driven feedback platform for individual EM providers. We have outlined a framework for working alongside clinicians with a multidisciplined team to develop and test a tool that augments their clinical experience and enables closed-loop learning.
ABSTRACT
BACKGROUND: Out-of-hospital cardiac arrest (OHCA) remains one of the most common causes of death. There is a scarcity of evidence concerning the prevalence of bacteraemia in cardiac arrest patients presenting to the Emergency Department (ED). We aimed to determine the prevalence of bacteraemia in OHCA patients presenting to the ED, as well as study the association between bacteraemia and in-hospital mortality in OHCA patients. In addition, the association between antibiotic use during resuscitation and in-hospital mortality was examined. METHODS AND RESULTS: This was a study of 200 adult OHCA patients who presented to the ED between 2015 and 2019. Bacteraemia was confirmed if at least one of the blood culture bottles grew a non-skin flora pathogen or if two blood culture bottles grew a skin flora pathogen from two different sites. The prevalence of bacteraemia was 46.5%. Gram positive bacteria, specifically Staphylococcus species, were the most common pathogens isolated from the bacteremic group. 42 patients survived to hospital admission. The multivariate analysis revealed that there was no association between bacteraemia and hospital mortality in OHCA patients (OR = 1.3, 95% CI= 0.2-9.2) with a p-value of .8. There was no association between antibiotic administration during resuscitation and hospital mortality (OR = 0.6, 95% CI= 0.1 - 3.8) with a p-value of .6. CONCLUSION: In our study, the prevalence of bacteraemia among OHCA patients presenting to the ED was found to be 46.5%. Bacteremic and non-bacteremic OHCA patients had similar initial baseline characteristics and laboratory parameters except for higher serum creatinine and BUN in the bacteremic group. In OHCA patients who survived their ED stay there was no association between hospital mortality and bacteraemia or antibiotic administration during resuscitation. There is a need for randomised controlled trials with a strong patient oriented primary outcome to better understand the association between in-hospital mortality and bacteraemia or antibiotic administration in OHCA patients.KEY MESSAGESWe aimed to determine the prevalence of bacteraemia in OHCA patients presenting to the Emergency Department.

Abdominal and extremity complaints are common in the emergency department (ED) and, because of their frequency, clinical vigilance is vital in order not to miss the timely diagnosis of occult or delayed emergencies. Such emergencies, if not timely managed, are sources of significant patient morbidity and mortality and may expose ED physicians to possible litigation. Each patient complaint yields to a nuanced approach in diagnostics and therapeutics that can lead physicians toward the ruling in or out of the correct high-risk diagnosis. This article discusses the approach and risk management of this high-risk subset of abdominal and extremity diagnoses.

BACKGROUND: Pediatric oncology patients may be at a higher risk of complications and mortality from sepsis compared with their nononcology counterpart. OBJECTIVES: The aim of this study is to compare characteristics, treatment, and sepsis-related mortality between oncology and nononcology patients presenting to the emergency department (ED). METHODS: This is a retrospective single-center cohort study including patients <18 years old with a diagnosis of sepsis, severe sepsis, septic shock, or bacteremia presenting to an academic ED between January 2009 and January 2015. A total of 158 patients were included with 53.8% having an underlying malignancy. The primary outcome of the study was in-hospital mortality. Secondary outcomes included ED vital signs, resuscitation parameters, laboratory work, infection site, general practitioner unit, intensive care unit length of stay, and hospital length of stay. RESULTS: Oncology patients had a higher in-hospital mortality (5.9% vs. 2.7%), however, it did not meet statistical significance (p = 0.45). On presentation, oncology patients had a lower respiratory rate (24.33 ± 9.48 vs. 27.45 ± 7.88; p = 0.04). There was a significant increase in the white blood count in oncology patients (4.011 ± 4.965 vs. 17.092 ± 12.806; p < 0.001) with this cohort receiving more intravenous fluids. In the first 6 hours (33.0 ± 27.7 mL/kg vs. 24.9 ± 16.1 mL/kg; p = 0.029) as well as having a higher percentage of vasopressor administration (15.3% vs. 1.4%; p = 0.002). Antibiotics were initiated at an earlier stage in the oncology cohort (1.25 ± 1.95 vs. 3.33 ± 1.97 hours; p < 0.0001). Cancer-free patients had a significantly higher rate of lung infections compared with cancer patients (68.5% vs. 32.9%; p < 0.0001). In terms of infection characteristics, cancer patients had a higher percentage of bacteremia (27.1% vs. 4.1%; p < 0.001). CONCLUSION: There was no statistical significance regarding mortality between the 2 cohorts. Pediatric cancer patients were found to have a higher incidence of bacteremia and received more aggressive treatment.

BACKGROUND: EGDT (Early Goal Directed Therapy) or some portion of EGDT has been shown to decrease mortality secondary to sepsis and septic shock. OBJECTIVE: Our study aims to assess the effect of adopting this approach in the emergency department on in-hospital mortality secondary to sepsis/septic shock in Lebanon. HYPOTHESIS: Implementation of the EGDT protocol of sepsis in ED will decrease in-hospital mortality. METHODS: Our retrospective study included 290 adult patients presenting to the ED of a tertiary center in Lebanon with severe sepsis and/or septic shock. 145 patients between years 2013 and 2014 who received protocol care were compared to 145 patients treated by standard care between 2010 and 2012. Data from the EHR were retrieved about patients' demographics, medical comorbidities, and periresuscitation parameters. A multivariate analysis using logistic regression for the outcome in-hospital mortality after adjusting for protocol use and other confounders was done and AOR was obtained for the protocol use. 28-day mortality, ED, and hospital length of stay were compared between the two groups. RESULTS: The most common infection site in the protocol arm was the lower respiratory tract (42.1%), and controls suffered more from UTIs (33.8%). Patients on protocol care had lower in-hospital mortality than that receiving usual care, 31.7% versus 47.6% (p=0.006) with an AOR of 0.429 (p =0.018). Protocol patients received more fluids at 6 and 24 hours (3.8 ± 1.7 L and 6.1 ± 2.1 L) compared to the control group (2.7 ± 2.0 L and 4.9 ± 2.8 L p=<0.001). Time to and duration of vasopressor use, choice of appropriate antibiotics, and length of ED stay were not significantly different between the two groups. CONCLUSION: EGDT- (Early Goal Directed Therapy-) based sepsis protocol implementation in EDs decreases in-hospital mortality in developing countries. Adopting this approach in facilities with limited resources, ICU capabilities, and prehospital systems may have a pronounced benefit.
ABSTRACT
BACKGROUND: Emergency Department (ED) visits for suicide attempts have been described worldwide; however, the populations studied were predominantly Western European, North American, or East Asian. This study aims to describe the epidemiology of ED patients presenting post-suicide attempt to an academic medical center in Lebanon and to report on factors that affect ED disposition. METHODS: A retrospective cohort study was conducted between 2009 and 2015. Patients of any age group were included if they had presented to the ED after a suicide attempt. Patients with unintentional self-harm were excluded. Descriptive analysis was performed on the demographics and characteristics of suicide attempts of the study population. A bivariate analysis to compare the two groups (hospitalized or discharged) was conducted using Student's t test and Pearson Chi-square where appropriate. A multivariate analysis was then conducted to determine the predictors of hospital admission. RESULTS: One hundred and eight patients were included in the final analysis. Most patients were females (71.4%) and between 22 and 49 years of age. A considerable number of patients were unemployed (43%), unmarried (61.1%), and living with family (86.9%). Most suicide attempts were performed at home (93.5%) and on a weekday (71.3%). The most common mechanisms of injury were overdose with prescription medications (61.3%), overdose with over-the-counter drugs (27.9%), and self-inflicted lacerations (10.1%). The classes of medication most commonly abused were benzodiazepines (39.3%) followed by acetaminophen (27.3%). A large portion of our patients were admitted (70.3%), with the majority going to the psychiatric ward (71.1%). Of note, a quarter (27.5%) of our patients left the ED against medical advice, with 23.5% of admitted patients leaving the hospital before completion of treatment. The main predictors of admission were found to be overdose on prescription medications OR 9.25 (2.12-40.42 CI95%). CONCLUSIONS: The characteristics of our suicide attempters mirror those of international and regional suicide attempters. Further work is required to quantify the effect of voluntary refusal of hospital treatment, the repercussions of family, and financial barriers to healthcare and suicide as a whole in our society.
ABSTRACT
BACKGROUND: The epidemiology of burns is well described in the United States, Europe and Asia. However, few studies address this topic in the Levant region. This study aims to describe characteristics of burn victims treated at the emergency department of a tertiary care center in Beirut, Lebanon and to report on factors that affect ED disposition. METHODS: A retrospective cohort study was conducted in the ED of a tertiary care hospital, in Beirut, Lebanon, between 2009 and 2013. Patients were recruited if their final ED diagnosis was burn. A descriptive analysis of patients' characteristics including burns was done, followed by a bivariate analysis to compare two groups (admitted vs discharged). Statistical analysis included the use of Student t-test and Pearson chi-square where appropriate. A multivariate analysis was then conducted to determine the predictors of hospital admission. RESULTS: A total of 366 patients had their charts queried. Age category distributions of the patients were 73 (19.9%) <5 years, 39 (10.7%) 5-14 years, 236 (64.5%) 15-65 years and 18 (4.9%) >65 years of age. Around half of the patients (47.3%) were males, with scalding being the most common mechanism of burn (53.9%), followed by contact with hot object (16.8%) and flame (11.9%). In terms of disposition from the ED, 58 (15.8%) patients were admitted to the hospital with 42 (72.4%) going to GPU, 12 (20.6%) to ICU and 4(6.9%) transferred to either another hospital or to an acute burn facility. Admitted patients tended to be at the extremes of ages (<5 years or ≥65 years), male dominant, more likely to be brought in by family, with higher proportions of more severe mechanisms of injury (flame, electric, chemical). Admitted patients also sustained higher degrees of burns with more TBSA injured. Predictors of hospital admission included the aforementioned factors with the strongest predictors of admission being full-thickness degree burn (OR 18.56 (4.67-73.72 CI95% p≤0.001)) and mechanism of injury such as electrical (OR 23.01 (3.23-163.89 CI95% p=0.002)) and chemical (OR 17.43 (2.33-130.14 CI95% p=0.003)). CONCLUSION: Characteristics of burn patients treated in an urban ED in Lebanon mirror those of burn victims in other international studies. Future larger epidemiologic studies are needed to better quantify the impact of burns in Lebanon.

BACKGROUND: The emotional consequences of patient deaths on physicians have been studied in a variety of medical settings. Reactions to patient death include distress, guilt, and grief. Comparatively, there are few studies on the effects of patient death on physicians and residents in the Emergency Department (ED). The ED setting is considered unique for having more sudden deaths that likely include the young and previously healthy and expectations for the clinician to return to a dynamic work environment. To date, no studies have looked at the effects of patient deaths on the more vulnerable population of medical students in the ED. This study examined aspects of patient deaths in the ED that most strongly influence students' reactions while comparing it to those of an inpatient setting. METHODS: Semi-structured qualitative interviews were carried out with a total of 16 medical students from the American University of Beirut, Medical Center in Lebanon who had recently encountered a patient death in the ED. Questions included their reaction to the death, interaction with patients and their family members, the response of the medical team, and coping mechanisms adopted. RESULTS: The analysis revealed the following as determinant factors of student reaction to patient death: context of death; including age of patient, expectation of death, first death experience, relating patient death to personal deaths, and extent of interaction with patient and family members. Importantly, deaths in an inpatient setting were judged as more impactful than ED deaths. ED deaths, however, were especially powerful when a trauma case was deemed physically disturbing and cases in which family reactions were emotionally moving. CONCLUSION: The study demonstrates that students' emotional reactions differ as a function of the setting (surprise and shock in the ED versus sadness and grief in an inpatient setting). Debriefing and counseling sessions on ED deaths may benefit from this distinction.

BACKGROUND: Elevated lactate has been found to be associated with a higher mortality in a diverse patient population. The aim of the study is to investigate if initial serum lactate level is independently associated with hospital mortality for critically ill patients presenting to the Emergency Department. METHODS: Single-center, retrospective study at a tertiary care hospital looking at patients who presented to the Emergency Department (ED) between 2014 and 2016. A total of 450 patients were included in the study. Patients were stratified to lactate levels: <2 mmol/L, 2-4 mmol/L and >4 mmol/L. The primary outcome was in-hospital mortality. Secondary outcomes included 72-h hospital mortality, ED and hospital lengths of stay. RESULTS: The mean age was 64.87 ± 18.08 years in the <2 mmol/L group, 68.51 ± 18.01 years in the 2-4 mmol/L group, and 67.46 ± 17.67 years in the >4 mmol/L group. All 3 groups were comparable in terms of age, gender and comorbidities except for diabetes, with the 2-4 mmol/L and >4 mmol/L groups having a higher proportion of diabetic patients. The mean lactate level was 1.42 ± 0.38 (<2 mmol/L), 2.72 ± 0.55 (2-4 mmol/L) and 7.18 ± 3.42 (>4 mmol/L). In-hospital mortality was found to be 4 (2.7%), 18(12%) and 61(40.7%) patients in the low, intermediate and high lactate groups respectively. ED and hospital length of stay were longer for the >4 mmol/L group as compared to the other groups. While adjusting for all variables, patients with intermediate and high lactate had 7.13 (CI 95% 2.22-22.87 p = 0.001) and 29.48 (CI 95% 9.75-89.07 p = <0.001) greater odds of in-hospital mortality respectively. DISCUSSION: Our results showed that for all patients presenting to the ED, a rising lactate value is associated with a higher mortality. This pattern was similar regardless of patients' age, presence of infection or blood pressure at presentation. CONCLUSION: Higher lactate values are associated with higher hospital mortalities and longer ED and hospital lengths of stays. Initial ED lactate is a useful test to risk-stratify critically ill patients presenting to the ED.

OBJECTIVES: The purpose of this meta-analysis was to determine the sensitivity, specificity, and positive and negative predictive values of contrast-enhanced ultrasound (US) for confirming the tip location and placement of central venous catheters in adult patients. METHODS: A systematic review was performed using electronic databases, including MEDLINE, ClinicalTrials.gov, Cochrane, Embase, PubMed, and Scopus. Inclusion criteria were studies conducted on adult patients receiving an internal jugular or a subclavian central venous catheter in the emergency department or intensive care unit. Furthermore, the catheter tip location had to be checked with the use of the agitated saline contrast-enhanced US technique. RESULTS: A total of 2245 articles were screened by title and abstract. Seventeen articles were retrieved and assessed for the predefined inclusion criteria. Four articles and 1 abstract were used in the final analysis. Contrast-enhanced US showed pooled sensitivity of 72% (95% confidence interval, 44%-91%), pooled specificity of 100% (95% confidence interval, 99%-100%), a positive predictive value of 92.1%, and a negative predictive value of 98.5% compared with chest radiography for confirming the placement of central venous catheters. CONCLUSIONS: In the setting of central venous catheter placement, postprocedural contrast-enhanced US imaging is a safe, efficient, and highly specific confirmatory test for the catheter tip location compared with chest radiography.

OBJECTIVE: Most sepsis studies have looked at the general population. The aim of this study is to report on the characteristics, treatment and hospital mortality of patients with cancer diagnosed with sepsis or septic shock. SETTING: A single-centre retrospective study at a tertiary care centre looking at patients with cancer who presented to our tertiary hospital with sepsis, septic shock or bacteraemia between 2010 and 2015. PARTICIPANTS: 176 patients with cancer were compared with 176 cancer-free controls. PRIMARY AND SECONDARY OUTCOMES: The primary outcome of this study was the in hospital mortality in both cohorts. Secondary outcomes included patient demographics, emergency department (ED) vital signs and parameters of resuscitation along with laboratory work. RESULTS: A total of 352 patients were analysed. The mean age at presentation for the cancer group was 65.39±15.04â years, whereas the mean age for the control group was 74.68±14.04â years (p<0.001). In the cancer cohort the respiratory system was the most common site of infection (37.5%) followed by the urinary system (26.7%), while in the cancer-free arm, the urinary system was the most common site of infection (40.9%). intravenous fluid replacement for the first 24â hours was higher in the cancer cohort. ED, intensive care unit and general practice unit length of stay were comparable in both the groups. 95 (54%) patients with cancer died compared with 75 (42.6%) in the cancer-free group. The 28-day hospital mortality in the cancer cohort was 87 (49.4%) vs 46 (26.1%) in the cancer-free cohort (p=0.009). Patients with cancer had a 2.320 (CI 95% 1.225 to 4.395, p=0.010) odds of dying compared with patients without cancer in the setting of sepsis. CONCLUSIONS: This is the first study looking at an in-depth analysis of sepsis in the specific oncology population. Despite aggressive care, patients with cancer have higher hospital mortality than their cancer-free counterparts while adjusting for all other variables.
