Incidence and outcomes of delayed intracranial hemorrhage: a population-based cohort study

Head trauma is a common reason for emergency department (ED) visits. Delayed intracranial hemorrhage (ICH) in patients with minor head trauma is a major concern, but controversies exist regarding the incidence of delayed ICH and discharge planning at the ED. This study aimed to determine the incidence of delayed ICH in adults who developed ICH after a negative initial brain computed tomography (CT) at the ED and investigate the clinical outcomes for delayed ICH. This nationwide population cohort study used data from the National Health Insurance Service of Korea from 2013 to 2019. Adult patients who presented to an ED due to trauma and were discharged after a negative brain CT examination were selected. The main outcomes were the incidence of ICH within 14 days after a negative brain CT at initial ED visit and the clinical outcomes of patients with and without delayed ICH. The study patients were followed up to 1 year after the initial ED discharge. Cox proportional hazard regression analysis was used to estimate the hazard ratio for all-cause 1-year mortality of delayed ICH. During the 7-year study period, we identified 626,695 adult patients aged 20 years or older who underwent brain CT at the ED due to minor head trauma, and 2666 (0.4%) were diagnosed with delayed ICH within 14 days after the first visit. Approximately two-thirds of patients (64.3%) were diagnosed with delayed ICH within 3 days, and 84.5% were diagnosed within 7 days. Among the patients with delayed ICH, 71 (2.7%) underwent neurosurgical intervention. After adjustment for age, sex, Charlson Comorbidity Index, and insurance type, delayed ICH (adjusted hazard ratio, 2.15; 95% confidence interval, 1.86–2.48; p < 0.001) was significantly associated with 1-year mortality. The incidence of delayed ICH was 0.4% in the general population, with the majority diagnosed within 7 days. These findings suggest that patient discharge education for close observation for a week may be a feasible strategy for the general population.

Fentanyl-positive urine drug screens in the emergency department: Association with intentional opioid misuse and racial disparities

BackgroundAn increase in opioid-related overdoses, notably from potent synthetic opioids like fentanyl, prompted this consideration of characteristics of emergency department (ED) patients with evidence for illicit fentanyl use or exposure, the correlation with intentional opioid misuse, and subsequent ED management. MethodsA retrospective review was performed of patients presenting to an urban academic medical center ED with evidence for illicit fentanyl use, determined by positive urine drug screens (UDS), from 6/2021 through 11/2021. Participant demographics, comorbidities, ED chief complaint and disposition, and evidence of intentional opioid misuse were considered. Secondary outcomes included provision of buprenorphine/naloxone and/or naloxone kits at discharge, ED recidivism, and six-month mortality. Bivariate comparisons and logistic regression models were performed. ResultsAmong 409 unique patients, most were white and male with a mean age of 39.4. Approximately half presented with opioid-related complaints. Evidence of intentional opioid misuse was identified in 72.6 % of patients. Black patients had 79 % lower odds of intentional opioid misuse compared to white patients. Regarding ED management, 28.8 % were discharged with buprenorphine/naloxone and 14.0 % with a naloxone kit. Black patients had 63 % lower odds of receiving buprenorphine/naloxone compared to white patients after controlling for covariates. Nearly 6 % of the study population died within six months of the initial ED visit. ConclusionThis fentanyl-focused review describes patient characteristics which largely mirror the epidemiology of the current opioid epidemic; however, despite evidence of objective exposure, it also suggests that Black patients may be less likely to use fentanyl intentionally. It also highlights potential disparities related to ED-based opioid misuse patient management.

Trends in recurrent overdose and treatment initiation following emergency department visits for opioid overdose between 2016 and 2021

BackgroundOverdose remains a pressing public health concern in the United States, particularly with the emergence of fentanyl and other potent synthetic opioids in the drug supply. We evaluated trends in recurrent overdose and opioid use disorder (OUD) treatment initiation following emergency department (ED) visits for opioid overdose to inform response efforts. MethodsThis retrospective cohort study used electronic health record and statewide administrative data from Rhode Island residents who visited EDs for opioid overdose between July 1, 2016, and June 30, 2021, a period with fentanyl predominance in the local drug supply. The primary outcome was recurrent overdose in the 365 days following the initial ED visit. OUD treatment initiation within 180 days following the initial ED visit was considered as a secondary outcome. Trends in study outcomes were summarized by year of the initial ED visit. ResultsAmong 1745 patients attending EDs for opioid overdose, 20 % (n=352) experienced a recurrent overdose within 365 days, and this percentage was similar by year (p=0.12). Among patients who experienced any recurrent overdose, the median time to first recurrent overdose was 88 days (interquartile range=23–208), with 85 % (n=299/352) being non-fatal. Among patients not engaged in OUD treatment at their initial ED visit, 33 % (n=448/1370) initiated treatment within 180 days; this was similar by year (p=0.98). ConclusionsFollowing ED visits for opioid overdose in Rhode Island from 2016–2021, the one-year risk of recurrent overdose and six-month treatment initiation rate remained stable over time. Innovative prevention strategies and improved treatment access are needed.

A Comprehensive Evaluation of Emergency Department Utilization by Patients With Cirrhosis.

Emergency department (ED)-based care is required for cirrhosis management, yet the burden of cirrhosis-related ED healthcare utilization is understudied. We aimed to describe ED utilization within a statewide health system and compare the outcomes of high ED use (HEDU) vs non-HEDU in individuals with cirrhosis. We retrospectively reviewed charts of adults with cirrhosis who presented to any of 16 EDs within the Indiana University Health system in 2021. Patient characteristics, features of the initial ED visit, subsequent 90-day healthcare use, and 360-day outcomes were collected. Multivariable logistic regression models were used to identify predictors HEDU status which was defined as ≥2 ED visits within 90 days after the index ED visit. There were 2,124 eligible patients (mean age 61.3 years, 53% male, and 91% White). Major etiologies of cirrhosis were alcohol (38%), metabolic dysfunction-associated steatohepatitis (27%), and viral hepatitis (21%). Cirrhosis was newly diagnosed in the ED visit for 18.4%. Most common reasons for ED visits were abdominal pain (21%), shortness of breath (19%), and ascites/volume overload (16%). Of the initial ED visits, 20% (n = 424) were potentially avoidable. The overall 90-day mortality was 16%. Within 90 days, there were 366 HEDU (20%). Notable variables independently associated with HEDU were model for end-stage liver disease-sodium (adjusted odds ratio [aOR] 1.044, 95% confidence interval [CI] 1.005-1.085), prior ED encounter (aOR 1.520, 95% CI 1.136-2.034), and avoidable initial ED visit (aOR 1.938, 95% CI 1.014-3.703). Abdominal pain, shortness of breath, and ascites/fluid overload are the common presenting reasons for ED visits for patients with cirrhosis. Patients with cirrhosis presenting to the ED experience a 90-day mortality rate of 16%, and among those who initially visited the ED, 20% were HEDU. We identified several variables independently associated with HEDU. Our observations pave the way for developing interventions to optimize the care of patients with cirrhosis presenting to the ED and to lower repeated ED visits.

Socially vulnerable patients are more likely to fail outpatient management of symptomatic cholelithiasis

BackgroundSymptomatic cholelithiasis is a common surgical problem, with many patients requiring multiple gallstone-related emergency department (ED) visits before cholecystectomy. The Social Vulnerability Index (SVI) identifies vulnerable patient populations. This study aimed to assess the association between social vulnerability and outpatient management of symptomatic cholelithiasis. MethodsPatients with symptomatic cholelithiasis–related ED visits were identified within our health system from 2016 to 2022. Clinical outcomes data were merged with SVI census track data, which consist of 4 SVI subthemes (socioeconomic status, household characteristics, racial and ethnic minority status, and housing type and transportation). Multivariate analysis was used for statistical analysis. ResultsA total of 47,292 patients presented to the ED with symptomatic cholelithiasis, of which 6103 patients (13.3 %) resided in vulnerable census tract regions. Of these patients, 13,795 (29.2 %) underwent immediate cholecystectomy with a mean time to surgery of 35.1 h, 8250 (17.4 %) underwent elective cholecystectomy at a mean of 40.6 days from the initial ED visit, and 2924 (6.2 %) failed outpatient management and returned 1.26 times (range, 1–11) to the ED with recurrent biliary–related pain. Multivariate analysis found social vulnerability subthemes of socioeconomic status (odds ratio [OR], 1.29; 95 % CI, 1.09–1.52) and racial and ethnic minority status (OR, 2.41; 95 % CI, 2.05–2.83) to be associated with failure of outpatient management of symptomatic cholelithiasis. ConclusionSocially vulnerable patients are more likely to return to the ED with symptomatic cholelithiasis. Policies to support this vulnerable population in the outpatient setting with timely follow-up and elective cholecystectomy can help reduce delays in care and overutilization of ED resources.

Non-fatal self-harm and suicide following postpartum psychiatric emergency department visits: A population-based retrospective cohort study

In a population-based cohort of postpartum individuals in Ontario, Canada, this study aimed to determine the risk of non-fatal self-harm and suicide within one year of an initial postpartum psychiatric emergency department (ED) visit (2008–2020), and the key associated factors. Of 16,475 postpartum individuals with psychiatric ED visits, 714 (4.3 %) had non-fatal self-harm within one year, and 23 (0.15 %) died by suicide. Risk was substantially higher for those with self-harm at the initial presentation. Further efforts to connect individuals with postpartum psychiatric ED visits with needed inpatient care and outpatient follow-up are required to reduce non-fatal self-harm and suicide risk.

Behavioural ‘nudging’ interventions to reduce low-value care for low back pain in the emergency department (NUDG-ED): protocol for a 2×2 factorial, before-after, cluster randomised trial

IntroductionOpioids and imaging are considered low-value care for most people with low back pain. Yet around one in three people presenting to the emergency department (ED) will receive imaging, and...

Evaluating the impact of a discharge pharmacy in the emergency department on emergency department revisits and admissions

ImportanceMedication nonadherence leads to worse health outcomes, increased healthcare service utilization, and increased overall healthcare costs. ObjectiveTo determine whether a discharge pharmacy located in the Emergency Department (ED) reduces ED revisits and hospitalizations. DesignThis is a cohort study where we extracted data from our electronic medical records with adult encounters between 12/2019–10/2021. For the purpose of this study, we defined a revisit to the ED as within 7 days and an admission within 30 days from prior initial ED visit. SettingThe University of Chicago Medicine is an academic medical center located in Chicago's South Side. ParticipantsBetween dates of 12/2019–11/2021, we had 78,660 adult distinct encounters. We created 5 different groups: no medications prescribed, ED discharge pharmacy only, e-prescriptions to outside pharmacies, combination of ED pharmacy and e-prescription sent elsewhere, and printed prescriptions with or without any e-prescriptions. ExposureOur ED pharmacy is located within the adult ED, serving only patients seen and discharged from the adult ED. Main Outcome(s) and Measure(s)Our primary endpoint is to evaluate if prescribing and dispensing prescriptions from only our ED pharmacy is associated with decreased ED revisits within 7 days and reduced hospitalizations within 30 days of initial ED visit. ResultsWhen comparing patients who received prescriptions only from the ED discharge pharmacy, patients who received no prescriptions were 31.6% (P < 0.001) more likely to revisit our ED, and patients who received e-prescriptions sent to other pharmacies were 10.4% (P = 0.017) more likely to revisit. Patients who received e-prescriptions from other pharmacies were 29.2% (P < 0.001) more likely to be hospitalized and mixture of e-prescriptions were 59.5% (P < 0.001) more likely to be hospitalized compared to the ED pharmacy only group. Conclusions and RelevanceWe believe having a pharmacy providing medications to patients being discharged from the ED reduces barriers like cost, transportation, and pharmacy access patients face trying to fill prescriptions at their local pharmacy. All of these reductions in barriers provides an easier and more convenient method for patients to obtain their medications at discharge from the ED, reducing the risk of a repeat ED visit and subsequent hospital admission.

Economic burden and secondary complications of influenza-related hospitalization among adults in the US: a retrospective cohort study

Objective This study aims to describe the healthcare resource utilization (HCRU) and direct medical cost of influenza-related hospitalizations to illustrate the persistent economic burden of influenza among adults in the US. Methods A retrospective cohort study was conducted using the PINC AI Healthcare Database. Adults hospitalized with a diagnosis of influenza between August 1–May 31 from 2016–2023 were identified and stratified by age (18–49, 50–64 and ≥65 years). The index hospitalization was defined as the individual’s first influenza-related hospitalization during each season. Patient demographics, comorbidities, and hospitalization characteristics were assessed during the index hospitalization. Index hospitalization length of stay (LOS), in-hospital mortality, intensive care unit (ICU) admissions, mechanical ventilation (MV) usage, and costs were evaluated overall and by MV usage, ICU admission, and secondary complication status. Pre-index influenza-related outpatient and emergency department (ED) visits (7 days prior) were also evaluated. Results Primarily initiated in the ED, the median LOS for influenza-related hospitalizations was 3–4 days. Inpatient mortality increased with age (2.2–4.4%). Combined mean hospitalization and initial ED visit costs were $12,556–$14,494 (2017/18; high severity season) and $11,384–$12,896 (2022/23; most recent season). Compared to other age groups, adults ≥65 years had higher proportions of hospitalization with no MV or ICU usage. Adults 18–49 years had the highest proportion of ICU admission only, whereas adults 50–64 years had the highest MV usage only and both MV and ICU admission. MV and/or ICU usage was associated with higher hospitalization costs. Increasing proportionally with age, the majority of influenza-related hospitalizations had a secondary complication diagnosis, which were associated with elevated costs. Limitations Analysis of this hospital-based administrative database relied on coding accuracy. Only hospital system-associated outpatient/ED visits were captured; the full scope of HCRU was under-ascertained. Conclusions The economic burden of influenza-related hospitalizations remains substantial, driven by underlying conditions, MV/ICU usage and secondary complications.

The pattern of emergency department utilization in pediatric patients who underwent interfacility transfers from the emergency department: a nationwide population-based study in South Korea, 2016-2018

Purpose: The shortage of pediatric emergency care has become a significant societal issue. This study investigated the usage pattern of emergency departments (EDs) by pediatric patients who underwent interfacility transfers (IFTs) in South Korea, focusing on cases involving single and double IFTs.Methods: This nationwide cross-sectional study included all pediatric patients (&lt; 19 years) who underwent IFTs at regional and local emergency medical centers from 2016 through 2018, using data from the National Emergency Department Information System. After excluding unidentified cases, clinical features and ED use patterns were compared between patients with single IFT, i.e., an IFT after the initial ED visit, and those with double IFT, i.e., a sequential transfer from one medical facility to another.Results: Among 20,888 pediatric cases of IFTs in the ED, 21.0% of disease cases (3,070/14,624) and 11.4% of injury cases (691/6,038) experienced double IFTs. The double-transfer group showed a lower proportion of high acuity than the single-transfer group (22.6% vs. 15.0%; P &lt; 0.001). However, median values of ED length of stay were longer in the double-transfer group, regardless of type of cases (disease: 163 minutes [single] vs. 218 minutes [double]; injury, 111 minutes vs. 172 minutes; all Ps &lt; 0.001). Guardian’s request was a substantial reason for double IFT (disease, 29.9% [919/3,070]; injury, 56.4% [390/691]).Conclusion: Double IFT is common in pediatric patients and strains medical resources, regardless of severity. The high occurrence of double IFT driven by guardians’ requests rather than medical emergencies underscores the need for improved awareness of the emergency medical system among pediatric patients’ caregivers.

Concurrent Alcohol and Opioid Intoxication in Emergency Department Patients Leads to Greater Resource Utilization

Background: Concurrent alcohol intoxication can complicate emergency department (ED) presentations for opioid-related adverse events. We sought to determine if there was a difference in resource utilization among patients who presented to the ED with concurrent opioid and alcohol intoxication compared to opioid intoxication alone. Methods: Using linked state-wide databases from the Maryland Healthcare Cost and Utilization Project (HCUP), we identified patients with a diagnosis of opioid intoxication treated in the ED from 2016 to 2018. We measured healthcare utilization for each patient in the ED settings for one year after the initial ED visit and estimated direct costs. We performed logistic regression comparing patients presented with co-intoxication to those without. Results: Of 12,295 patients who presented to the ED for opioid intoxication during the study period, 703 (5.7%) had concurrent alcohol intoxication. Patients with co-intoxication had more recurrent ED visits (340 vs 247.4 per 1000 patients, p < 0.05), higher index ED visit admission rates (26.9% vs 19.4%, p < 0.001), but similar overall costs ($3736 vs $2861, p < 0.05) at one year. Co-intoxication was associated with suicidal ideation (OR = 1.58, 95% CI 1.51–1.65), high zip code income (OR = 1.16, 95% CI 1.12–1.21), and higher rates of intoxication with all classes of drugs analyzed (p < 0.001). Conclusion: Our study demonstrated that mental health disorders, socioeconomic status, and increased ED utilization are associated with co-intoxication of opioids and alcohol presenting to the ED. Further research is needed to elucidate factors responsible for the increased resource use in this population.

Cost-effectiveness of modified diagnostic strategy to safely rule-out pulmonary embolism in the emergency department: a non-inferiority cluster crossover randomized trial (MODIGLIA-NI)

BackgroundThe aim of this trial-based economic evaluation was to assess the incremental costs and cost-effectiveness of the modified diagnostic strategy combining the YEARS rule and age-adjusted D-dimer threshold compared with the control (which used the age-adjusted D-dimer threshold only) for the diagnosis of pulmonary embolism (PE) in the Emergency Department (ED).MethodsEconomic evaluation from a healthcare system perspective alongside a non-inferiority, crossover, and cluster-randomized trial conducted in 16 EDs in France and two in Spain with three months of follow-up. The primary endpoint was the additional cost of a patient without failure of the diagnostic strategy, defined as venous thromboembolism (VTE) diagnosis at 3months after exclusion of PE during the initial ED visit. Mean differences in 3-month failure and costs were estimated using separate generalized linear-regression mixed models, adjusted for strategy type, period, and the interaction between strategy and period as fixed effects and the hospital as a random effect. The incremental cost-effectiveness ratio (ICER) was obtained by dividing the incremental costs by the incremental frequency of VTE.ResultsOf the 1,414 included patients, 1,217 (86%) were analyzed in the per-protocol analysis (648 in the intervention group and 623 in the control group). At three months, there were no statistically significant differences in total costs (€-46; 95% CI: €-93 to €0.2), and the failure rate was non inferior in the intervention group (-0.64%, one-sided 97.5% CI: -∞ to 0.21%, non-inferiority margin 1.5%) between groups. The point estimate of the incremental cost-effectiveness ratio (ICER) indicating that each undetected VTE averted in the intervention group is associated with cost savings of €7,142 in comparison with the control group. There was a 93% probability that the intervention was dominant. Similar results were found in the as randomized population.ConclusionsGiven the observed cost decrease of borderline significance, and according to the 95% confidence ellipses, the intervention strategy has a potential to lead to cost savings as a result of a reduction in the use of chest imaging and of the number of undetected VTE averted. Policy-makers should investigate how these monetary benefits can be distributed across stakeholders.ClinicaltrialsTrial registration number ClinicalTrials.gov Identifier: NCT04032769; July 25, 2019.

Risk factors for recurrent emergency care utilization for flares in inflammatory bowel disease.

Patients with inflammatory bowel disease (IBD) need frequent emergency care due to flares of their disease. However, understanding which patients are most vulnerable to repeat emergency care due to recurrent flares of their disease remains poor. This was a retrospective cohort study of Kaiser Permanente Northern California health plan members aged ≥18 years between 2009 and 2018. Our primary outcome was occurrence of repeat emergency department (ED) visits with a primary diagnosis code of IBD in the 6 months following their index ED visit. Baseline characteristics and clinical service use patterns were extracted. We used multivariable negative binomial regression analysis to measure the incident risk of a recurrent ED visit within 6 months. We found 2111 patients who met eligibility criteria, of whom 56.7% were female and 39.7% were non-White. During the 6-month observation period, 19.3% (n = 408) returned to the ED for a second IBD flare. In adjusted analyses, we found older age (incident risk ratio [IRR] 0.44, 95% confidence interval [CI] 0.31-0.62 for age 60+ compared to 18-30), higher neighborhood household income (IRR 0.80, 95% CI 0.65-0.98 for income ≥$85,000), and diagnosis of alcohol use disorder were associated with a lower risk of repeat ED utilization (IRR 0.62, 95% CI 0.41-0.93), while presence of mood disorder (IRR 1.26, 95% CI 1.03-1.58), history of opiate prescription (IRR 1.38, 95% CI 1.10-1.73), and corticosteroid prescription (IRR 1.57, 95% CI 1.27-1.95) were associated with increased risk of repeat ED utilization. Prompt outpatient follow-up was not associated with a lower odds of recurrent ED utilization (IRR 0.93, 95% CI 0.75-1.15). Our study identified multiple patient characteristics associated with higher recurrent short-term use of the ED for IBD care. Although we did not find prompt outpatient follow-up after initial ED visit to be protective, targeted interventions directed at high-risk individuals based on mood disorders, opiate use, or steroid use may help to optimize care and health care utilization.

Evaluating the impact of emergency department clinical pharmacist integration within a discharge urine culture follow‐up program

AbstractIntroductionPatients are often discharged from the emergency department (ED) prior to final culture results, leading to the development of post‐ED discharge urine culture review programs (UCRPs) to ensure appropriate management. The purpose of this study was to evaluate the impact ED pharmacists have on antibiotic management and determine areas for improved antimicrobial stewardship efforts.MethodsThis was a single‐system, retrospective, quasi‐experimental study of patients who visited the ED for evaluation of a urinary tract infection comparing no pharmacist involvement in a culture review to a process when ED pharmacists were involved. Patients included those discharged from the ED requiring review under a UCRP. Incarcerated patients and those admitted to an inpatient service from the ED were excluded. The primary outcome was the receipt of guideline‐appropriate management. Secondary outcomes included unplanned admission or ED revisit within 14 and 30 days related to the initial ED visit, all‐cause hospital admission or ED revisit within 14 and 30 days, and acceptance rate of pharmacist recommendations.ResultsA total of 142 patients were included (before pharmacist integration = 70, after pharmacist integration = 72). Receipt of guideline‐appropriate management occurred at 33% without pharmacist integration and 85% in the arm with pharmacist integration, p &lt; 0.001. Pharmacist recommendations were accepted in 97% of cases. No difference was noted between ED revisit within 14 and 30 days with a chief complaint directly related to the initial ED visit, 14 and 30 day admission related to the initial encounter, and all‐cause hospital admission or ED revisit within 14 and 30 days. In patients with asymptomatic bacteriuria, there was a higher receipt of inappropriate management 67% (20/30) in the time before pharmacist integration versus 19% (9/48) after pharmacist integration (p &lt; 0.001).ConclusionThere was a significantly higher number of patients with appropriate antimicrobial management after pharmacist involvement in UCRP review.

Misdiagnosis of acute basilar artery occlusion (BAOs) in the emergency department in vietnam: A single-center, retrospective, cross-sectional study

BackgroundIschemic stroke caused by basilar artery occlusions (BAOs) poses a risk for misdiagnosis, leading to an increase the rates of mortality and disability, particularly in low-, and middle-income countries. Methods: A retrospective and cross-sectional study evaluated 21 patients with an initial misdiagnosis of BAO among 110 BAO patients from 7 district hospitals who were subsequently admitted to the stroke center at the 103 Military Hospital from June 2021 to September 2022 in Ha Noi city, Vietnam. Patient data collected were age, sex, medical history, initial diagnosis, neuroradiologic findings, and treatment outcome at 1 month after hospital discharge. Results: The rate for misdiagnosis for BAOs in the initial emergency department (ED) was 19.1%. The average patient age was 68.9 (63–81) years. The most common symptom at the disease onset was dizziness, followed by altered consciousness, seizures, quadriplegia, hemiplegia, functional swallowing disorder, and breathing disorders. Vestibular disorder was the most common misdiagnosis of BAOs, followed by epilepsy, hypoglycemia, and delirium tremens, impaired consciousness with unknown cause, polyneuritis, and aspiration pneumonia. Cerebral infarction was not detected in all brain computed tomography images, but was detected in brain magnetic resonance images. The average score of the Modified Rankin Scale was 5.4 ± 0.5, and 47.6% of the patients who died after 1 month from the hospital discharge. Conclusion: Misdiagnosis of BAOs at the initial ED visit resulted in serious consequences. We highly recommend the use of brain magnetic resonance imaging as the preferred imaging method for patients with suspected BAOs who present to the ED.All authors certify that they have participated sufficiently in the work to take public responsibility for the content, including participation in the concept, design, analysis, writing, or revision of the manuscript.

Comparison of syncope risk scores in predicting the prognosis of patients presenting to the emergency department with syncope.

Various scores have been derived for the assessment of syncope patients in the emergency department (ED). We aimed to compare the effectiveness of Canadian Syncope Risk Scores (CSRS), San Francisco Syncope Rules (SFSR), and Osservatorio Epidemiologico sulla Sincope nel Lazio (OESIL) risk scores in predicting the risk of major adverse cardiac events (MACE) and mortality among syncope patients within 30days of the initial ED visit. We performed a prospective, observational case series study of adults (≥ 18years) with unexplained syncope/near-syncope who presented to ED. Demographic characteristics of the patients and clinical and laboratory data were recorded in the standard data collection form of the study. Our primary outcome was a 30-day mortality. A total of 421 patients (mean age 50.9 ± 20.8, 51.5% male) were enrolled. The rate of MACE development in the 30-day follow-up of the patients was 12.8% (n = 54). While 20.2% (n = 85) of the patients were hospitalized, two of the patients died in the emergency room and the 30-day mortality was 5.5% (n = 23). CSRS was found to have the highest predictive power of mortality (AUC: 0.869, 95% CI 0.799-0.939, p < 0.001). If the cut-off value of CSRS was 0.5, the sensitivity was found to be 82.6% and the specificity was 81.9%. Also CSRS (OR: 1.402, 95% CI: 1.053-1.867, p = 0.021) was found to be an independent predictor of the 30-day mortality. The CSRS may be used as a safety risk score for a 30-day risk of MACE and mortality after discharge from the emergency department.

Effects of Delayed Surgical Intervention Following Emergency Department Presentation on Stone Surgery Complexity.

Introduction and Objective: Prior literature had demonstrated increased stone burden and higher rates of staged surgery in individuals of lower socioeconomic status (SES). Low SES individuals are more likely to experience delays in definitive stone surgery after initial presentation to the emergency department (ED) for kidney stones. This study aims to investigate the relationship between delays in definitive kidney stone surgery and the subsequent need for percutaneous nephrolithotomy (PNL) and/or staged surgical procedures using a statewide data set. Methods: This retrospective cohort study gathered longitudinal data from 2009 to 2018 using the California Department of Health Care Access and Information data set. Patient demographic characteristics, comorbidities, diagnosis/procedure codes, and distance were analyzed. Complex stone surgery was defined as initial PNL and/or undergoing more than one procedure within 365 days of initial intervention. Results: A total of 1,816,093 billing encounters from 947,798 patients were screened, resulting in 44,835 patients with ED visits for kidney stones followed by a urologic stone procedure. Multivariable analysis revealed that relative to patients who underwent surgery within 1 month of initial ED visit for stone disease, patients were at increased odds of undergoing complex surgery if waiting ≥6 months (odds ratio [OR] 1.18, p = 0.022), ≥1 year (OR 1.29, p < 0.001), and ≥3 years (OR 1.43, p < 0.001). Conclusions: Delays in definitive stone surgery after initial ED encounter for stone disease were associated with increased likelihood of undergoing a complex stone treatment.

Gaps in care following first time seizure in an underserved region: A retrospective analysis

PurposeThis study investigated the characteristics of patients presenting with the first-time seizure (FTS) and whether neurology follow-up occurred in a medically underserved area. MethodsA retrospective study of adults with a FTS discharged from the Emergency Department (ED) at Loma Linda University between January 1, 2017 and December 31, 2018 was performed. The primary outcome was days from the ED visit to the first neurology visit. Secondary outcomes included repeat ED visits, percentage of patients who had specialty assessment in one year, type of neurologist seen, and percentage lost to follow-up. ResultsOf the 1327 patients screened, 753 encounters met criteria for manual review, and after exclusion criteria were applied, 66 unique encounters were eligible. Only 30% of FTS patients followed up with a neurologist. The median duration for neurology follow-up was 92 days (range=5–1180). After initial ED visit, 20% of follow-up patients were diagnosed with epilepsy within 189 days, and 20% of patients re-presented to the ED with recurrent seizures while awaiting their initial neurology appointment. Reasons for lack of follow-up included: referral issues, missed appointments, and shortage of available neurologists. ConclusionThis study highlights the significant treatment gap that a first-time seizure clinic (FTSC) could fill in underserved communities. FTSC may reduce the morbidity and mortality associated with untreated recurrent seizures.

The adjusted impact of different severities of acute exacerbations and medications on the risk of developing dementia in COPD patients

BackgroundAlthough a relationship between chronic obstructive pulmonary disease (COPD) and dementia has been reported, the initial severity upon emergency department (ED) visits and the medications used have not been well evaluated as risk factors for increased dementia occurrence. We aimed to analyze the risks of dementia development over 5 years among patients with COPD compared to matched controls (primary) and the impact of different severities of acute exacerbations (AEs) of COPD and medications on the risk of dementia development among COPD patients (secondary).MethodThis study used the Taiwanese government deidentified health care database. We enrolled patients during the 10-year study period (January 1, 2000, to December 31, 2010), and each patient was followed up for 5 years. Once these patients received a diagnosis of dementia or died, they were no longer followed up. The study group included 51,318 patients who were diagnosed with COPD and 51,318 matched (in terms of age, sex, and the number of hospital visits) non-COPD patients from the remaining patients as the control group. Each patient was followed up for 5 years to analyze the risk of dementia with Cox regression analysis. Data on medications (antibiotics, bronchodilators, corticosteroids) and severity at the initial ED visit (ED treatment only, hospital admission, or ICU admission) were collected for both groups, as well as demographics and baseline comorbidities, which were considered confounding factors.ResultsIn the study and control groups, 1,025 (2.0%) and 423 (0.8%) patients suffered from dementia, respectively. The unadjusted HR for dementia was 2.51 (95% CI: 2.24–2.81) in the study group. Bronchodilator treatment was associated with the HRs, especially among those who received long-term (> 1 month) treatment (HR = 2.10, 95% CI: 1.91–2.45). Furthermore, among 3,451 AE of COPD patients who initially visited the ED, patients who required ICU admission (n = 164, 4.7%) had a higher risk of dementia occurrence (HR = 11.05, 95% CI: 7.77–15.71).ConclusionBronchodilator administration might be associated with a decreased risk of dementia development. More importantly, patients who suffered AEs of COPD and initially visited the ED and required ICU admission had a higher risk of developing dementia.
