Oakland score to identify low-risk patients with lower gastrointestinal bleeding performs well among emergency department patients

BackgroundThe Oakland Score predicts risk of 30-day adverse events among hospitalized patients with lower gastrointestinal bleeding (LGIB) possibly identifying patients who may be safe for discharge. The Oakland Score has not been studied among emergency department (ED) patients with LGIB. The Oakland Score composite outcome includes re-bleeding, defined as additional blood transfusion requirements and/or a further decrease in hematocrit (Hct) >/= 20% after 24 h in clinical stability; red blood cell transfusion; therapeutic intervention to control bleeding, including surgery, mesenteric embolization, or endoscopic hemostasis; in-hospital death, all cause; and re-admission with further LGIB within 28 days. Prediction variables include age, sex, previous LGIB admission, systolic blood pressure, heart rate, and hemoglobin concentration, and scores range from 0 to 35 points, with higher scores indicating greater risk.MethodsRetrospective cohort study of adult (≥ 18 years old) patients with a primary ED diagnosis of LGIB across 21 EDs from March 1st, 2018, through March 1st, 2020. We excluded patients who were more likely to have upper gastrointestinal bleeding (esophago-gastroduodenoscopy without LGIB evaluation), patients who left against medical advice or prior to ED provider evaluation, ED patients without active health plan membership, and patients with incomplete Oakland Score variables. We assessed predictive accuracy by reporting the area under the receiver operator curve (AUROC) and sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios at multiple clinically relevant thresholds.ResultsWe identified 8,283 patients with LGIB, 52% were female, mean age was 68, 49% were non-White, and 27% had an adverse event. The AUROC for predicting an adverse event was 0.85 (95% CI 0.84–0.86). There were 1,358 patients with an Oakland Score of </=8; 4.9% had an adverse event, and sensitivity of the Oakland Score at this threshold was 97% (95% CI 96%−98%).ConclusionThe Oakland Score had high predictive accuracy among ED patients with LGIB. Prospective evaluation is needed to understand if the risk score could augment ED decision-making and improve outcomes and resource utilization.

388. Co-Testing: Increasing HIV Testing in Patients Undergoing Sexually Transmitted Infection Evaluation in a Large Integrated Healthcare Network

Abstract Background Utah ranks last among states in the percentage (26.5%) of adults ever tested for Human Immunodeficiency Virus (HIV). We hypothesized that linking “co-testing” for HIV to evaluations for sexually transmitted infections (STIs) in Urgent Care (UC) and Emergency Departments (ED) would increase HIV screening. We implemented a multifaceted intervention in the UCs and EDs of our integrated health system and evaluated its impact on HIV co-testing. Methods The initiative included education and HIV test follow-up support along with an electronic medical record-embedded alert (Figure 1). The alert surfaced if gonorrhea (GC), chlamydia (CT), or other STI testing was ordered for patients ≥ 18 years with unknown HIV status and encouraged HIV testing if not already ordered. We sequentially implemented the initiative in 26 UC and 22 ED sites from April 2023 – December 2023. We used interrupted time series analysis to evaluate HIV co-testing rates among eligible GC/CT testing encounters in pre-implementation (April 1st, 2022 – March 31st, 2023) and post-implementation (April 1st, 2023 – March 31st, 2024) UC and ED cohorts. We compared the observed rate to the predicted counterfactual (had no intervention taken place). We also assessed co-testing by social determinants of health (SDOH) categories, alert volume, and system impact on HIV testing and diagnoses. Results During the 24-month study, there were 19,232 GC/CT test encounters: 5,730 UC/2,524 ED pre-implementation and 7,696 UC/3,282 ED post-implementation. In UC, the increase in the observed HIV GC/CT co-test rate vs the predicted was 14.5 percentage points (95% CI 9.08-20.06, p&amp;lt; 0.001) (Figure 2). In the ED, the increase in the observed HIV GC/CT co-test rate vs the predicted was 13.7 percentage points (95% CI 5.75-21.71, p&amp;lt; 0.001). HIV GC/CT co-testing varied by SDOH (Table 1). 4,704 alerts fired (54% UC/46% ED) and resulted in 730 HIV co-tests (225 UC/505 ED), representing a 15.5% engagement rate. Of these 730 alert-initiated HIV co-tests, 5 (0.7%) revealed new HIV diagnoses, representing 29% of all HIV diagnoses in UC and ED during the post-implementation period (Figure 3). Conclusion HIV co-testing in our UC and ED sites increased during a multifaceted initiative. New HIV diagnoses occurred in UC and ED as a result of HIV testing ordered via our alert.

Epidemiology of diagnostic errors in pediatric emergency departments using electronic triggers.

We applied three electronic triggers to study frequency and contributory factors of missed opportunities for improving diagnosis (MOIDs) in pediatric emergency departments (EDs): return visits within 10 days resulting in admission (Trigger 1), care escalation within 24 h of ED presentation (Trigger 2), and death within 24 h of ED visit (Trigger 3). We created an electronic query and reporting template for the triggers and applied them to electronic health record systems of five pediatric EDs for visits from 2019. Clinician reviewers manually screened identified charts and initially categorized them as "unlikely for MOIDs" or "unable to rule out MOIDs" without a detailed chart review. For the latter category, reviewers performed a detailed chart review using the Revised Safer Dx Instrument to determine the presence of a MOID. A total of 2937 ED records met trigger criteria (Trigger 1 1996 [68%], Trigger 2 829 [28%], Trigger 3 112 [4%]), of which 2786 (95%) were categorized as unlikely for MOIDs. The Revised Safer Dx Instrument was applied to 151 (5%) records and 76 (50%) had MOIDs. The overall frequency of MOIDs was 2.6% for the entire cohort, 3.0% for Trigger 1, 1.9% for Trigger 2, and 0% for Trigger 3. Brain lesions, infections, or hemorrhage; pneumonias and lung abscess; and appendicitis were the top three missed diagnoses. The majority (54%) of MOIDs cases resulted in patient harm. Contributory factors were related to patient-provider (52.6%), followed by patient factors (21.1%), system factors (13.2%), and provider factors (10.5%). Using electronic triggers with selective record review is an effective process to screen for harmful diagnostic errors in EDs: detailed review of 5% of charts revealed MOIDs in half, of which half were harmful to the patient. With further refining, triggers can be used as effective patient safety tools to monitor diagnostic quality.

Emergency Department Use Within 90 Days After Single-Level Posterior Cervical Foraminotomy.

This study sought to characterize the incidence of, timing of, predictive factors for, and reasons for emergency department (ED) visits within 90 days of single-level posterior cervical foraminotomy (PCF). These visits, after PCF, have received limited attention. The 2010-2022 M161 PearlDiver database was queried for elective single-level PCFs, excluding multilevel procedures, midline laminectomies, fusions, or other posterior/anterior procedures, as well as indications of trauma, infection, or neoplasm. Patient age, sex, Elixhauser Comorbidity Index (ECI), insurance, and region were extracted. Weekly ED use after PCF was calculated. Multivariate analyses were used to identify predictive factors for ED use, and primary ED diagnoses were categorized. Of 10,588 PCF patients, 9.09% (n=962) visited the ED within 90 days after surgery, mostly in the first 4 weeks. Multivariate analysis identified that predictors included younger age (odds ratio [OR], 1.02 per decade decrease), female sex (OR, 1.19), higher ECI (OR, 1.28 for ECI 1-2; OR, 1.41 for ECI 3-4; OR, 1.51 for ECI ≥5), Midwest (OR, 1.16) or Northeast (OR, 1.19) region, and Medicare (OR, 1.09) or Medicaid (OR, 1.57) coverage. In the first 4 weeks, 69.9% of ED visits were related to the surgical site; this decreased to 27.1% thereafter. Almost one-tenth of PCF patients visited the ED within 90 days after surgery. Specific patient characteristics were associated with ED visits, with surgical site-related diagnoses predominating in the acute postoperative period. Tailoring health care interventions based on timing of, risk factors for, and causes of ED visits may enhance outcomes and reduce costs. [Orthopedics. 202x;4x(x):xx-xx.].

Optimizing the Use of Computed Tomography for Appendicitis Diagnosis in the Pediatric Emergency Department Through the Quality Improvement Methodology.

Acute appendicitis is one of the most common causes of an acute abdomen among pediatric patients. The diagnosis of appendicitis is challenging due to the nonspecific presentation. Diagnosis is based on historical, physical, and serologic information as well as right lower quadrant ultrasound (RLQ US). In equivocal patients, or those with a high degree of suspicion, computed tomography (CT) of the abdomen and pelvis with intravenous (IV) contrast can be utilized to rule in appendicitis. However, optimizing diagnostic protocols to minimize ionizing radiation exposure while maintaining diagnostic accuracy is important. We performed a monthly retrospective analysis of CT usage among pediatric patients with suspected acute appendicitis presenting to the pediatric emergency department (ED) from June 2023 to December 2023. We used quality improvement methodology to decrease CT use with monthly Plan-Do-Study-Act (PDSA) cycles with an aim to decrease CT use by 50%. The main intervention was coordination between the ED and surgical providers to require surgical consult before ordering a CT. We quantified the number of patients who received a surgical consult before CT, the number of RLQ US performed, the number of CTs performed, and the number of appendectomies, specifically the number with perforation. A total of 249 patients under 18 years of age presented to the pediatric ED with symptoms of acute appendicitis during the study period. All 249 patients underwent an initial RLQ US.The number of CTs performed decreased from a baseline of 14 in June to a nadir of four in September (71% decrease, p=0.029). There was a decrease in the percentage of patients who underwent a CT scan after an RLQ US from 36.5% in June to 11.8% in September after our intervention. In June, a total of 38 RLQ USwere performed and 14 patients underwent additional CT (36.5%) and in September a total of 34 US were performed and 14 patients underwent additional CT (11.8%).There was an increase in the surgical consults rate from a baseline of seven surgical consults with 14 total CTs in June 2023 (50%) to seven consults with a total of seven CTs performed(100%) in December 2023. There was no increase in appendiceal perforation rates. Multidisciplinary discussions between pediatric ED physicians and pediatric surgeons reduced CT usage, and corresponding radiation exposure and cost, in the evaluation of appendicitis.

Implementation of Electronic Triggers to Identify Diagnostic Errors in Emergency Departments

Missed diagnosis can lead to preventable patient harm. To develop and implement a portfolio of electronic triggers (e-triggers) and examine their performance for identifying missed opportunities in diagnosis (MODs) in emergency departments (EDs). In this retrospective medical record review study of ED visits at 1321 Veterans Affairs health care sites, rules-based e-triggers were developed and implemented using a national electronic health record repository. These e-triggers targeted 6 high-risk presentations for MODs in treat-and-release ED visits. A high-risk stroke e-trigger was applied to treat-and-release ED visits from January 1, 2016, to December 31, 2020. A symptom-disease dyad e-trigger was applied to visits from January 1, 2018, to December 31, 2019. High-risk abdominal pain, unexpected ED return, unexpected hospital return, and test result e-triggers were applied to visits from January 1, 2019, to December 31, 2019. At least 100 randomly selected flagged records were reviewed by physician reviewers for each e-trigger. Data were analyzed between January 2024 and April 2024. Treat-and-release ED visits involving high-risk stroke, symptom-disease dyads, high-risk abdominal pain, unexpected ED return, unexpected hospital return, and abnormal test results not followed up after initial ED visit. Trained physician reviewers evaluated the presence/absence of MODs at ED visits and recorded data on patient and clinician characteristics, types of diagnostic process breakdowns, and potential harm from MODs. The high-risk stroke e-trigger was applied to 8 792 672 treat-and-release ED visits (4 967 283 unique patients); the symptom-disease dyad e-trigger was applied to 3 692 454 visits (2 070 979 patients); and high-risk abdominal pain, unexpected ED return, unexpected hospital return, and test result e-triggers were applied to 1 845 905 visits (1 032 969 patients), overall identifying 203, 1981, 170, 116 785, 14 879, and 2090 trigger-positive records, respectively. Review of 625 randomly selected patient records (mean [SD] age, 62.5 [15.2] years; 553 [88.5%] male) showed the following MOD counts and positive predictive values (PPVs) within each category: 47 MODs (PPV, 47.0%) for stroke, 31 MODs (PPV, 25.8%) for abdominal pain, 11 MODs (PPV, 11.0%) for ED returns, 23 MODs (PPV, 23.0%) for hospital returns, 18 MODs (PPV, 18.0%) for symptom-disease dyads, and 55 MODs (PPV, 52.4%) for test results. Patients with MODs were slightly older than those without (mean [SD] age, 65.6 [14.5] vs 61.2 [15.3] years; P < .001). Reviewer agreement was favorable (range, 72%-100%). In 108 of 130 MODs (83.1%; excluding MODs related to the test result e-trigger), the most common diagnostic process breakdown involved the patient-clinician encounter. In 185 total MODs, 20 patients experienced severe harm (10.8%), and 54 patients experienced moderate harm (29.2%). In this retrospective medical record review study, rules-based e-triggers were useful for post hoc detection of MODs in ED visits. Interventions to target ED work system factors are urgently needed to support patient-clinician encounters and minimize harm from diagnostic errors.

JYNNEOS vaccine safety surveillance in the vaccine safety datalink during the 2022 mpox outbreak in the United States.

The JYNNEOS vaccine (two doses given 28 days apart) was recommended in the United States for people at high risk of exposure to monkeypox virus during the 2022 mpox outbreak. Our objective was to assess the safety of JYNNEOS using two complementary epidemiologic methods. This observational cohort included patients of eight large integrated healthcare organizations who received JYNNEOS. Adverse events were identified using ICD-10 coded diagnoses assigned to medical visits. The first analysis used standardized incidence ratios (SIR) to compare the observed incidence of ten prespecified adverse events of special interest (AESI) during the 28 days after receipt of each dose of JYNNEOS to the expected incidence adjusted for several risk factors. The second analysis used tree-based data mining to identify temporal clustering of cases for more than 60,000 diagnoses and diagnosis groups within 70-days after JYNNEOS dose 1 administration. The SIR analysis included 53,583 adults who received JYNNEOS dose 1 and 38,206 who received dose 2. Males received 92% of the doses. There were no statistically significant elevated SIRs for any of the ten AESI. The tree-based data mining analysis included 36,912 vaccinees. Analysis of diagnoses in inpatient, emergency department, and outpatient settings identified statistically significant clusters of visits for rash and unspecified adverse effects. No new or unexpected safety concerns were identified. AESI did not occur more frequently than expected by chance alone. Non-serious medically attended adverse events, such as rash, have been previously reported and occurred infrequently.

Can a chest pain virtual ward be used to safely manage patients with low-risk acute coronary syndrome?

Abstract Background Acute coronary syndrome (ACS) accounts for approximately 2-6% of emergency department (ED) presentations and contributes at least 20% of the overall acute hospital admissions(1-3). Patients presenting with low-risk ACS may be suitable for remote monitoring(4) while awaiting angiogram in chest pain virtual ward(CPVW) thereby improving patient flow and resource utilisation. Purpose We aimed to assess outcomes for patients with low-risk ACS admitted in a district general hospital with a view to establish an onboarding pathway for CPVW whilst ensuring a safe monitoring without effecting the readmission rate or all-cause mortality. Methods We retrospectively analysed the Myocardial Ischaemia National Audit Project (MINAP) registry of from March 2022 to April 2023 for patients who presented to ED with a diagnosis of confirmed ACS. Patients were stratified into low-risk (GRACE score &amp;lt;140, HEART score &amp;lt;4, non-dynamic ECG, non-dynamic troponin, without ongoing chest pain), all other patients were deemed intermediate-to-high-risk ACS. Baseline demographics, the total length of acute admission days, waiting time before and after coronary investigation ,adverse events (escalation of therapy, death)whilst awaiting for invasive inpatient angiogram were calculated. The primary endpoint was 30-day readmission and all-cause mortality. Results 1077 patients were coded as ACS diagnosis in ED. 561(52.1%) had a confirmed diagnosis of ACS. Data to allow stratification was available for 538 patients, included in final analysis. 377(70.1%) were male with a mean age of 66.8 ± SD 13.1 years. A significant number of patients had other comorbidities, including hypertension (66.1%), diabetes (45.3%), hyperlipidaemia (51.3%), and previous history of IHD (46.5%). Total number of patients stratified into low-risk ACS was 55(10.2%), intermediate-to-high-risk group contained 483(89.8%) patients. The median total-length-of-stay (LOS) for low-risk ACS patients was 4 days(IQR 2-7), waiting time to have an inpatient angiogram was 3 days(IQR 0-5), and discharge time post-angiogram was 1 day(IQR 0-2). 4 patients(7.3%) in low-risk cohort required CCU admission for GTN infusion due to ongoing chest pain, among them 3 patients(5.5%) had abnormal coronary angiogram. 5 patients(9.1%) in low-risk cohort were readmitted due to chest pain post-angiogram and no patients had 30-days or 1-year all-cause mortality. The result depicts 51 patients from low-risk cohort would have been eligible for CPVW reducing the LOS from median 4 days to 1-2 days, this is a saving of 102-153 acute bed days per year. Assuming the costing of a bed day is £320 this equates to £32,640 - £48,960 cost saving without any adverse outcomes. Conclusion Our data suggests that there is a large cost saving with minimal risk in managing patients with low-risk ACS via a CPVW. This pathway of management is likely to have benefit in patient flow and resource utilisation in our district general hospital trust.Comparison of different ACS cohortsCPVW flow-diagram

Youth mental health care use during COVID-19: Evidence from administrative data in Alberta, Canada

Abstract Background The COVID-19 pandemic affected health care service delivery and accessibility. Our study examined how Canadian youth used mental health services before and during the COVID-19 pandemic, and whether youth access and use patterns differed for subgroups based on social determinants previously associated with health care access. Methods Cross-sectional population-based administrative health care data from the province of Alberta in Canada was used to examine youth (ages 15-24) mental health care use from 2018/19 to 2021/22. Data was analyzed using an interrupted time series design and segmented regression modeling on type of mental health care use. Outcome measures were mental health care use for: general physician visits, psychiatrist visits, emergency department, hospitalization, and different mental health diagnoses. We stratified by factors related to social determinants, including gender and socioeconomic status. Results The analysis indicates an overall increase in the proportion of youth that used mental health care from 2018/19 to 2021/22 (14.4% vs 17.5%, respectively). There was an immediate drop in use with the onset of the COVID-19 pandemic in Canada, followed by a steady rise during the pandemic years, which was largely due to an increase in general physician visits. This rise was seen for most mental health diagnoses of study (i.e., anxiety, adjustment, attention-deficit/hyperactivity disorder, schizophrenia, and self-harm disorders). Service use increased for young women/girls compared to young men/boys and for youth from wealthier neighborhoods. Conclusions This study provides evidence to support health services planning and delivery to respond to the mental health needs of youth and to prepare for future public health emergencies. Key messages • Our study findings indicate changes in health care use for mental health among Canadian youth (ages 15-24) during the COVID-19 pandemic, with use patterns differing for youth subgroups. • Administrative health data can provide evidence to support health services planning and delivery to respond to the mental health needs of youth and to prepare for future public health emergencies.

JTH in Clinic: management of low-risk pulmonary embolism

Pulmonary embolism (PE) is a common cardiovascular disease diagnosis in emergency departments that can be associated with significant morbidity and mortality. One of the first steps after diagnosing PE is to risk stratify for adverse outcomes using risk scores such as PE Severity Index and European Society of Cardiology risk scheme. While intermediate- and high-risk PE patients should be admitted to the hospital, there is increasing evidence to support early discharge and home-based anticoagulation therapy for low-risk patients. The Hestia criteria encompass many of the clinicians’ considerations for who may be suitable for early discharge, considering both medical and social factors. Additionally, professional guidelines have provided algorithms on determining which low-risk patients may be suitable. Despite this, low-risk acute PE patients are still often admitted for inpatient treatment. In this review, we present a case-based approach on how to risk stratify and evaluate patients who may be good candidates for early discharge and home therapy.

Epidemiological comparison of emergency department presentations with seasonal influenza or COVID-19 and an outcome of intensive care admission or death: A population-based records linkage study in New South Wales, Australia

COVID-19 and seasonal influenza are endemic causes of morbidity and mortality. This study aimed to compare the epidemiology of severe illness and risk of death among patients following emergency department (ED) presentation with either infection. De-identified, population-based, emergency department records in New South Wales, Australia, were probabilistically linked to population-level health outcome databases for the period 1 January 2015 to 28 February 2023. Included were patients allocated an ED diagnosis consistent with an acute respiratory infection. Logistic regression was used to examine the association of infecting virus with risk of a severe outcome (intensive care unit admission or death). Influenza infection was notified in 2335 and COVID-19 in 5053 patients with a severe outcome. The age distribution was similar for both viruses, except in <15-year-olds, where severe influenza was nearly three times more frequent. Overall, the odds of death among patients with COVID-19 was 1.65 (95% CI 1.43, 1.89) times higher than among those with influenza. This declined to 1.49 (95% CI 1.08, 2.06) times during the COVID-19 Omicron variant period. The Omicron variant arrived when background population COVID-19 vaccination coverage was >90%. Despite that, death was more frequent for COVID-19 than influenza.

New recommendations of Spanish Society of Emergency Medicine (SEMES) for emergency department diagnosis of HIV infection based on results from Spain's "Leave Your Mark" program.

Hidden infections and late diagnoses are currently the main challenges of the HIV pandemic. Emergency departments (EDs) are one of the health care system's key resources addressing these challenges. In 2020, the Spanish Society of Emergency Medicine (SEMES) published recommendations for ordering HIV serology testing for patients with certain health conditions, and in 2021 SEMES launched the "Leave Your Mark" (Deja tu Huella - DTH) program to facilitate implementing the recommendations during emergency care. The present consensus paper, based on 3 years of experience with the program, was drafted to give new support to the DTH project. Participating hospitals ordered 129 617 serologies over 3 years, leading to 1620 new HIV diagnoses. One out of every 5 new HIV diagnoses in Spain is now made in an ED, but there is still room for improvement. To that end, this paper contributes 7 concrete proposals: 1) update the DTH program's criteria for ordering serology by including unexplained thrombocytopenia, fever with no focus of infection, and former residence in a country with endemic HIV infection; 2) include serology for hepatitis C virus infection at the time HIV testing is ordered; 3) reinforce the importance of obtaining the patient's informed consent for testing, meeting the obligation to respect the individual's rights; 4) implement educational programs; 5) develop decision-making tools (forms for ordering tests, alerts in patients' histories); 6) involve nurses in the DTH process and value their contributions; and 7) monitor quality markers to evaluate implementation of the program in all participating hospitals. The ultimate goal is to improve the DTH program and ensure its sustainability over time.

Association between Homelessness and Temperature-Related Health Emergencies in the United States

Abstract Temperature-related illness (TRI) encompasses heat-related illness, such as heat exhaustion and heatstroke, and cold-related illness, such as frostbite and hypothermia. TRI is typically the result of exposure to ambient weather conditions; because of this, unhoused individuals are hypothesized to have higher risk of TRI. However, no national epidemiological studies have been completed to determine this risk. The objective of this study was to determine the association between homelessness and emergency department (ED) diagnosis of TRI in the United States. We conducted a cross-sectional study of adult ED visits in the United States from 2005 through 2020 using data from the National Hospital Ambulatory Medical Care Survey (NHAMCS), a nationally representative sample of nonfederal ED patient visits. Housing status (housed versus unhoused) was measured using NHAMCS patient residence category, with blank responses excluded. TRI was defined as ED clinician diagnosis of heat- or cold-related illness using International Classification of Disease, versions 9 and 10 (ICD-9 and ICD-10) codes. Multivariable logistic regression was used to determine adjusted odds of TRI by housing status. There were 323 606 nonpediatric ED visits in the NHAMCS sample. TRI diagnosis was present in 288 (0.09%) visits. 4099 visits (0.9%) were categorized as unhoused. After adjusting for sex, mental health diagnosis, and alcohol or substance use or use disorder, the odds ratio of TRI diagnosis in unhoused individuals was 4.08 (95% CI 2.09, 7.95) compared to housed individuals. We found a higher adjusted odds ratio of TRI diagnosis at an ED visit among unhoused individuals compared with housed individuals. Significance Statement Temperature-related health emergencies, or illnesses caused by exposure to ambient weather conditions, affect numerous Americans each year and are expected to become more common as climate change continues. We wanted to understand whether unhoused individuals are at higher risk of these health emergencies. We used a national sample of emergency department visits in the United States to study this and found out that unhoused individuals are at more than four times the risk of these illnesses than housed individuals. Our work highlights the need for prevention of homelessness, stable housing for housing insecure populations, and heating and cooling centers during weather emergencies.

Improving Patient Understanding of Emergency Department Discharge Instructions.

Previous studies have shown that patients in the emergency department (ED) are frequently given incomplete discharge instructions that are written at least four grade levels above the recommended sixth-grade reading level, leading to poor understanding. Our aims in this study were to implement standardized discharge instructions containing six key components written at a more appropriate reading level for common emergency department (ED) diagnoses to improve patient understanding. We conducted this study in a 20-bed ED at an urban Veteran's Administration hospital. Data was collected via in-person patient and clinician interviews. Patient interviews were conducted after patients received their discharge instructions. We compared patient responses to clinician responses and marked them as incorrect, partially correct, or correct with a score of 0, 0.5, or 1, respectively. The maximum possible score for each interview was six. Six key components of discharge instructions were asked about: diagnosis; new medications; at-home care; duration of illness; reasons to return; and follow-up. There were 25 patients in the pre-intervention group and 20 in the intervention group with the standardized set of instructions. We performed a Mann-Whitney U test on the total interview scores in the control and intervention groups and conducted a sub-analysis on the individual scores for each of the six key components. The patients in the intervention demonstrated a statistically significant increase in patient-clinician correlation when compared to the patients in the pre-intervention group overall (P < 0.05), and two of the six key components of the discharge instructions individually showed statistically significant increase in patient-clinician correlation when standardized discharge instructions were used. Patients who received the standardized discharge instructions had improved understanding of their discharge instructions. Future opportunities extending off this pilot study include expanding the number of diagnoses for which standardized instructions are used and investigating patient-centered outcomes related to these instructions.

A Closer Look at Antipsychotic Adverse Effects: Investigating Anticholinergic Toxidrome Induced by Olanzapine Overdose

Background and Aims: Antipsychotic drugs are critical in managing psychosis but they also carry risks when misused, leading to toxicity. Case Presentation: A patient overdosed on olanzapine, resulting in anticholinergic toxidrome with symptoms like tachycardia and altered mental status. Immediate recognition and management of antipsychotic toxicity-induced toxidromes in emergency settings are crucial. Treatment strategy includes maintaining airway, breathing and circulation along with decontamination. There is no specific antidote. Conclusion: This case underscores the need for emergency physicians to remain vigilant and proactive in identifying and addressing such toxicity by identification of toxidromes to prevent complications and missed diagnosis in emergency department.

Material and methods: observational, longitudinal, retrospective study in patients who presented with lameness to the emergency department of a tertiary care hospital between 2019-2022. Patients were included by systematic random sampling. The study variables were: age, sex, time from onset, associated symptoms, history of trauma, personal and family history, source of referral (provider vs self), examination findings, diagnostic tests and results, treatment, diagnosis in emergency department, final diagnosis, aetiological group and discharge destination. Results: 321 patients, 65.1% male, with a mean age of 5.5 ± 3.4 years. Sixty percent sought care within 24 hours of onset and 81.6% were self-referred. Diagnostic tests were ordered in 87.5% (X-rays in 55.7%). The most common aetiology was inflammatory (29%), chiefly on account of transient synovitis (24%). We found an association between provider referral and a higher priority in triage (p=0.03), the use of ultrasound (p=0.009) and referral to outpatient specialists (p=0.003). The mean age of patients with abnormal sonographic findings (5.65 years) was higher compared to patients with normal results (3.84 years). There were also mean differences in the ages of the different aetiological groups (p=0.000) and in the different diagnoses made in the emergency department (p=0.002). We found an association between the presence of previous symptoms and the aetiological group (p=0.000) and between the time elapsed from onset to the visit and the aetiological group (p=0.002), interconsultation with traumatology (p=0.000) and destination after discharge (p =0.000). Conclusions: most causes of lameness are banal, but a high index of suspicion should be maintained for less frequent alternative diagnosis that may have more serious repercussions, such as JIA.

Stroke Risk After Emergency Department Treat-and-Release Visit for a Fall.

Previous cohort studies of hospitalized patients with a delayed diagnosis of ischemic stroke found that these patients often had an initial emergency department (ED) diagnosis of a fall. We sought to evaluate whether ED visits for a fall resulting in discharge to home (ie, treat-and-release visits) were associated with increased short-term ischemic stroke risk. A case-crossover design was used to compare ED visits for falls during case periods (0-15, 16-30, 31-90, and 91-180 days before stroke) and control periods (equivalent time periods exactly 1 year before stroke) using administrative data from the Healthcare Cost and Utilization Project on all hospital admissions and ED visits across 10 states from 2016 to 2020. To identify ED treat-and-release visits for a fall and patients hospitalized for acute ischemic stroke, we used previously validated International Classification of Diseases, Tenth Revision, Clinical Modification codes. Odds ratios and 95% CIs were calculated using conditional logistic regression. Among 90 592 hospitalized patients with ischemic stroke, 5230 (5.8%) had an ED treat-and-release visit for a fall within 180 days before their stroke. Patients with an ED treat-and-release visit for a fall were older (mean age, 74.7 [SD, 14.6] versus 70.8 [SD, 15.1] years), more often female (61.9% versus 53.4%), and had higher rates of vascular comorbidities than other patients with stroke. ED treat-and-release visits for a fall were significantly more common in the 15 days before stroke compared with the 15-day control period 1 year earlier (odds ratio, 2.7 [95% CI, 2.4-3.1]). The association between stroke and a preceding ED treat-and-release visit for a fall decreased in magnitude with increasing temporal distance from stroke. ED treat-and-release visits for a fall are associated with significantly increased short-term ischemic stroke risk. These visits may be opportunities to improve stroke diagnostic accuracy and treatment in the ED.
