Characteristics and risk of stroke in emergency department patients with acute dizziness

BackgroundAcute dizziness is a common symptom in the emergency department (ED), with strokes accounting for 3 %–5 % of cases. We investigated the risk of stroke in ED patients with acute dizziness and compared stroke characteristics diagnosed during and after the ED visit. MethodsWe identified adult patients with acute dizziness, vertigo, or imbalance using a hospital research-based database. Patients with abdominal or flank pain were used as the comparison group. Patients with dizziness were 1:1 matched to comparison patients. Each patient was traced for up to one year until being hospitalized for a stroke. ResultsOut of the 24,266 eligible patients, 589 (2.4 %) were hospitalized for stroke during the ED visit. For the remaining 23,677 patients, the risk of stroke at 7, 30, 90, and 365 days after ED discharge was 0.40 %, 0.52 %, 0.71 %, and 1.25 % respectively. Patients with dizziness had a higher risk of stroke compared to the comparison group at 7, 30, 90, and 365 days. The risk ratios decreased from 5.69 (95 % confidence interval [CI], 3.34–9.68) to 2.03 (95 % CI, 1.65–2.49). Compared to patients hospitalized for stroke during the ED visit, those hospitalized for stroke after the ED visit had greater stroke severity despite a lower initial triage acuity. Patients with early stroke (≤7 days) after ED discharge were less likely to have hypertension, diabetes, hyperlipidemia, and atrial fibrillation. They mostly experienced posterior circulation stroke. Patients with late stroke (>7 days) were older and less likely to have hypertension and hyperlipidemia but more likely to have a history of prior stroke and ischemic heart disease. Their strokes were mainly located in the anterior circulation territory. ConclusionsThe risk of stroke after ED discharge was higher in patients with dizziness than in the comparison group, with gradually decreasing risk ratios in the following year. Patients hospitalized for stroke during and after the ED visit had different profiles of vascular risk factors and clinical characteristics.

Outcomes for Young Adults With Suicide Admitted to Adult Versus Pediatric Hospitals.

To evaluate differences in care and outcomes for young adults admitted with suicide ideation (SI) or attempt (SA) to medical units of an adult (AH) versus pediatric hospital (PH). Demographic and clinical characteristics were collected on patients aged 18 to 25 years admitted to either an AH or PH at an academic health system from September 2017 through June 2023 with a diagnosis of SI or SA. Outcomes measured were discharge location, length of stay (LOS), emergency department (ED) visit or hospital readmission, and inpatient consultations. Bivariate tests and multivariate regression were used to determine association of admission location and outcomes. Of 212 patients included, 54% were admitted to an AH and 46% to a PH. Admission to a PH compared with an AH was associated with shorter ED LOS (4.3 vs 7.3 hours, P < .01) and discharge to home (57% vs 42%, P = .028) on bivariate but not adjusted analysis. Admission location was not associated with hospital LOS, ED visit or medical readmission after discharge, or psychiatry consultation. Admission to a PH compared with an AH was associated with higher odds of psychology consultation (29 vs 3%, P < .01). Although young adults admitted to a PH for SI/SA had higher rates of psychology consultation, they otherwise had similar care and outcomes regardless of admission to an AH versus a PH. Further work is needed to determine if observed differences are generalizable and how they affect hospital throughput and long-term outcomes.

Improving Guideline-Concordant Care for Febrile Infants Through a Quality Improvement Initiative.

We aimed to examine the impact of a quality improvement (QI) collaborative on adherence to specific recommendations within the American Academy of Pediatrics' Clinical Practice Guideline (CPG) for well-appearing febrile infants aged 8 to 60 days. Concurrent with CPG release in August 2021, we initiated a QI collaborative involving 103 general and children's hospitals across the United States and Canada. We developed a multifaceted intervention bundle to improve adherence to CPG recommendations for 4 primary measures and 4 secondary measures, while tracking 5 balancing measures. Primary measures focused on guideline recommendations where deimplementation strategies were indicated. We analyzed data using statistical process control (SPC) with baseline and project enrollment from November 2020 to October 2021 and the intervention from November 2021 to October 2022. Within the final analysis, there were 17 708 infants included. SPC demonstrated improvement across primary and secondary measures. Specifically, the primary measures of appropriately not obtaining cerebrospinal fluid in qualifying infants and appropriately not administering antibiotics had the highest adherence at the end of the collaborative (92.4% and 90.0% respectively). Secondary measures on parent engagement for emergency department discharge of infants 22 to 28 days and oral antibiotics for infants 29 to 60 days with positive urinalyses demonstrated the greatest changes with collaborative-wide improvements of 16.0% and 20.4% respectively. Balancing measures showed no change in missed invasive bacterial infections. A QI collaborative with a multifaceted intervention bundle was associated with improvements in adherence to several recommendations from the AAP CPG for febrile infants.

Impaired Standing Balance in Older Adults with Cognitive Impairment After a Severe Fall.

Introduction Fall-related sequelae as well as balance and gait impairments are more pronounced in older adults, who are cognitively impaired (OACI) compared to older adults who are cognitively healthy (OACH). Evidence is scarce about differences in standing balance and gait in OACH and OACI after a fall, even though these are major risks for recurrent falls. Thus, the aim of the study was to investigate early impairments in gait and balance, by adding Inertial Measurement Units (IMUs) to a functional performance test in OACH and OACI after a severe fall with presentation to the emergency department (ED) and immediate discharge. Methods The study sample was stratified into participants with and without probable cognitive impairment using the result of the Montreal Cognitive Assessment total score (maximum of 30 points). The cutoff for probable cognitive impairment was set at ≤ 24. Standing balance and gait parameters were measured using three IMUs in n=69 OACH (72.0 ± 8.2 years) and n=76 OACI (78.7 ± 8.1 years). Data were collected at participants' homes as part of a comprehensive geriatric assessment in the "SeFallED" study within four weeks after presentation to the ED after a severe fall (German Clinical Trials Register ID: 00025949). ANCOVA was used for statistical analysis, adjusted for age. Results The data indicated significantly more sway for OACI compared to OACH during balance tasks, whereas no differences in gait behavior were found. In detail, differences in standing balance were revealed for mean velocity (m/s) during parallel stance with eyes open (ηp2=0.190, p<0.001) and eyes closed on a balance cushion (ηp2=0.059, p=0.029), as well as during tandem stance (ηp2=0.034, p=0.044) between OACI and OACH. Further differences between the two groups were detected for path length (m/s2) during parallel stance with eyes open (ηp2=0.144, p<0.001) and eyes closed (ηp2=0.044, p<0.027) and for range (m/s2) during tandem (ηp2=0.036, p=0.036) and parallel stance with eyes closed (ηp2= 0.045, p=0.032). Conclusion Even though both groups have experienced a severe fall with presentation to the ED in the preceding 4 weeks, balance control among OACI indicated a higher fall risk than among OACH. Therefore, effective secondary falls prevention efforts have to be established, particularly for OACI.

Emergency department discharge practices for children with acute wheeze and asthma: a survey of discharge practice and review of safety netting instructions in the UK and Ireland

ObjectiveRecovery from acute wheeze and asthma attacks should be supported with safety netting, including treatment advice. We evaluated emergency department (ED) discharge practices for acute childhood wheeze/asthma attacks to describe...

An Analysis of New York Data: Fluctuations in Hospital Capacity Are Driven by Variability in Elective Admissions and Discharge Activity.

Background Hospital overcrowding compromises patient safety. The contribution of variability in admissions and discharges to overall hospital capacity needs to be quantified. This study describes the statewide day-to-day fluctuation in the volume of hospitalized patients, the variability and pattern of hospital admissions and discharges throughout the week, and the contribution of Emergency Department (ED) vs. elective (non-ED) admissions and discharges to the overall variability in the system across the week. Methodology This is a retrospective analysis of the New York State Statewide Planning and Research Cooperative System database, in which all New York healthcare facilities submit patient-level data monthly. The study period was from January 01 to December 31, 2015. Outcomes included total volumes of admissions and discharges and length of stay sorted by patient origin (ED vs. non-ED admits (elective)) and service type (medicine vs. surgery) by day of the week. Results We studied 1,692,090 hospital admissions. Admissions were highest on Mondays and Tuesdays and steadily decreased throughout the week. There was little variability in the ED admissions throughout the week. Surgical elective admissions had significant variability throughout the week, with higher admissions at the beginning of the week. There was a significant difference (p < 0.01) between admissions on weekdays vs. weekends. Discharges increased from Monday to Friday, with a dramatic drop on the weekends, for both ED and elective pathways. Systemwide, on Monday, hospitals were 21% above the mean volume, and on Fridays, hospitals were 32% below the mean volume. Conclusions Overall hospital capacity shows dramatic variability throughout the week, driven primarily by elective admissions and discharges from any source throughout the week. Because elective admissions are schedulable, hospitals can reduce variability by smoothing scheduling. Increased weekend discharges will also improve capacity.

Effect of transitioning from conventional cardiac troponin to high-sensitivity cardiac troponin on resource utilization- a single center experience

BackgroundCompared to conventional cardiac troponin (cTn), the high-sensitivity cardiac troponin (hs-cTn) assay is associated with improved detection of myocardial infarction (MI). MethodsWe performed a descriptive retrospective analysis of resource utilization at Rush University Medical Center over the transition period (July 1, 2021) from a cTn to a hs-cTn assay. Inclusion criteria included emergency department (ED) encounters between January 1 to December 31, 2021, with chief complaints of “chest pain” or “dyspnea” with associated troponin orders. The primary endpoint was the percentage of ED discharges. Secondary endpoints included the number of cardiac studies ordered. Univariable comparisons of these endpoints were performed using Student's t-test for continuous variables and Chi-square tests for binary/categorical variables. ResultsA total of 5113 encounters were analyzed. Hs-cTn was associated with an overall increase in ED patient discharges with negative troponin tests (44.1% vs. 29.9%, P < 0.01). In terms of cardiac testing per encounter, hs-cTn was associated with significant increases in the number of troponin tests (1.9 vs. 1.6, P < 0.01), electrocardiograms (3.0 vs. 2.9, P = 0.01), and echocardiograms (0.5 vs. 0.4, P < 0.01). There was a significant decrease in the utilization of stress testing (0.21 vs. 0.26, P < 0.01). There was a significant increase in total coronary angiography use during the hs-cTn period compared to cTn (227/2471 (9.2%) vs. 195/2642 (7.4%), P = 0.02). ConclusionTransitioning from cTn to hs-cTn was associated with significantly increased ED discharges and an increase in troponin tests, ECG, echocardiograms, and coronary angiograms. There was a decrease in the number of stress tests.

Characterization of peer support services for substance use disorders in 11 US emergency departments in 2020: findings from a NIDA clinical trials network site selection process.

Emergency departments (ED) are incorporating Peer Support Specialists (PSSs) to help with patient care for substance use disorders (SUDs). Despite rapid growth in this area, little is published regarding workflow, expectations of the peer role, and core components of the PSS intervention. This study describes these elements in a national sample of ED-based peer support intervention programs. A survey was conducted to assess PSS site characteristics as part of site selection process for a National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN) evaluating PSS effectiveness, Surveys were distributed to clinical sites affiliated with the 16 CTN nodes. Surveys were completed by a representative(s) of the site and collected data on the PSS role in the ED including details regarding funding and certification, services rendered, role in medications for opioid use disorder (MOUD) and naloxone distribution, and factors impacting implementation and maintenance of ED PSS programs. Quantitative data was summarized with descriptive statistics. Free-text fields were analyzed using qualitative content analysis. A total of 11 surveys were completed, collected from 9 different states. ED PSS funding was from grants (55%), hospital funds (46%), peer recovery organizations (27%) or other (18%). Funding was anticipated to continue for a mean of 16months (range 12 to 36months). The majority of programs provided "general recovery support (81%) Screening, Brief Intervention, and Referral to Treatment (SBIRT) services (55%), and assisted with naloxone distribution to ED patients (64%). A minority assisted with ED-initiated buprenorphine (EDIB) programs (27%). Most (91%) provided services to patients after they were discharged from the ED. Barriers to implementation included lack of outpatient referral sources, barriers to initiating MOUD, stigma at the clinician and system level, and lack of ongoing PSS availability due to short-term grant funding. The majority of ED-based PSSs were funded through time-limited grants, and short-term grant funding was identified as a barrier for ED PSS programs. There was consistency among sites in the involvement of PSSs in facilitation of transitions of SUD care, coordination of follow-up after ED discharge, and PSS involvement in naloxone distribution.

The effectiveness of parenteral agents for pain reduction in patients with migraine presenting to emergency settings: Asystematic review and network analysis.

To assess the comparative effectiveness and safety of parenteral agents for pain reduction in patients with acute migraine. Parenteral agents have been shown to be effective in treating acute migraine pain; however, the comparative effectiveness of different approaches is unclear. Nine electronic databases and gray literature sources were searched to identify randomized clinical trials assessing parenteral agents to treat acute migraine pain in emergency settings. Two independent reviewers completed study screening, data extraction, and Cochrane risk-of-bias assessment, with differences being resolved by adjudication. The protocol of the review was registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42018100096). A total of 97 unique studies were included, with most studies reporting a high or unclear risk of bias. Monotherapy, as well as combination therapy, successfully reduced pain scores prior to discharge. They also increased the proportion of patients reporting pain relief and being pain free. Across the pain outcomes assessed, combination therapy was one of the higher ranked approaches and provided robust improvements in pain outcomes, including lowering pain scores (mean difference -3.36, 95% confidence interval [CI] -4.64 to -2.08) and increasing the proportion of patients reporting pain relief (risk ratio [RR] 2.83, 95% CI 1.74-4.61). Neuroleptics and metoclopramide also ranked high in terms of the proportion of patients reporting pain relief (neuroleptics RR 2.76, 95% CI 2.12-3.60; metoclopramide RR 2.58, 95% CI 1.90-3.49) and being pain free before emergency department discharge (neuroleptics RR 4.8, 95% CI 3.61-6.49; metoclopramide RR 4.1, 95% CI 3.02-5.44). Most parenteral agents were associated with increased adverse events, particularly combination therapy and neuroleptics. Various parenteral agents were found to provide effective pain relief. Considering the consistent improvements across various outcomes, combination therapy, as well as monotherapy of either metoclopramide or neuroleptics are recommended as first-line options for managing acute migraine pain. There are risks of adverse events, especially akathisia, following treatment with these agents. We recommend that a shared decision-making model be considered to effectively identify the best treatment option based on the patient's needs.

Factors That Influence the Pain Response of Patients Admitted to an Emergency Department for Acute Musculoskeletal Trauma

Objective: To monitor factors influencing pain intensity variations in patients admitted to an emergency department (ED). Method: A prospective observational study included 904 patients. Pain intensity was assessed at ED admission and discharge using a novel Visual Analog Scale interpretation. Patient data included trauma type, pain location, the injury environment, age, race, and the time elapse between assessments. Results: Distinct personal, temporal and contextual factors revealed characteristic pain improvement, and worsening patterns post-ED management. Conclusions: The ED's pivotal role in pain relief, influenced by various factors, underscores the importance of optimizing patient care.

Antihypertensive prescription is associated with improved 30-day outcomes for discharged hypertensive emergency department patients.

Hypertension (HTN) is common in discharged emergency department (ED) patients, yet the short-term outcomes of treating HTN at ED discharge are unclear. This study aimed to investigate whether emergency physician (EP) prescription of oral antihypertensive therapy at ED discharge for hypertensive patients is associated with a decreased 30-day risk of the severe adverse events (AEs), death, and revisits to the ED. We conducted an observational cohort study assessing the 30-day outcomes of discharged ED patients with HTN, comparing outcomes based on whether antihypertensive therapy was prescribed. All discharged adult ED patients from an eight-hospital system with a diagnosis of HTN from January 2016 to February 2020 were screened, and consisted of a mix of suburban and urban patients with broad ethnic and socioeconomic backgrounds. Patients were categorized into the treatment group if they received a prescription for antihypertensive medication at ED discharge. The primary outcome was severe composite AEs from HTN (aortic catastrophe, heart failure, myocardial infarction, hemorrhagic and ischemic stroke, or hypertensive encephalopathy) within 30 days of ED discharge. The secondary outcomes were death or ED revisit over the same period. The study sample consisted of 93,512 ED visits; 57.5% were female, and mean age was 59.3 years. 4.7% of patients were prescribed antihypertensive treatment at ED discharge. Within 30 days, 0.7% of patients experienced an AE, 0.1% died, and 15.2% had an ED revisit. The treatment group had significantly lower odds of AE (adjusted odds ratio [aOR]: 0.224, 95%CI 0.106-0.416, p<0.001), and ED revisits (aOR: 0.610, 95%CI 0.547-0.678, p<0.001), adjusting for age, race, degree of HTN, ED treatment for elevated HTN, Elixhauser comorbidity index, and heart failure history. There was no difference in odds of death 30 days after discharge. Prescription antihypertensive therapy for discharged ED patients is associated with a 30-day decrease in severe adverse events and ED revisit rate.

Abstract P246: Geographical Mapping and Cluster Analysis of Ischemic Stroke in Kentucky

Background: Stroke death is the third leading cause of death in the United States, the sixth leading cause of death in Kentucky (KY), and ischemic stroke (IS) is the most prevalent type in adults (~85%). Small area estimates of stroke incidence can help identify local interventions to lower the burden of vascular risk factors and risk of recurrent IS in these areas. Therefore, the goals of this study are to calculate small area IS incidence rates, examine clusters, and understand the distribution of IS in KY. Methods: Data was obtained from the Kentucky Hospital Inpatient Discharge and Outpatient Services Databases (HIDOSD) from 2012 to 2021; and the Kentucky Cabinet for Health and Family Services. HIDOSD represents KY emergency department discharges, inpatient data, and ambulatory facility services. We linked 5-digit Zip codes to (n=759) zip code tabulation areas (ZCTA) available from the US Census Bureau. The annualized IS rate per 100,000 was calculated by dividing the mean number of IS hospitalizations from 2012 to 2021 by the ZCTA 2020 population. We categorized IS rates by quartiles and calculated box plots in descriptive analyses. We tested for significant spatial clusters using the Local Moran’s I with Empirical Bayes rate smoothing in GeoDa. Results: From 2012-2021, 90,840 IS hospitalizations were reported in KY. The median IS rate was 226.5 per 100,000. The median rate in the highest quartile was 290.8 (IQR 171.7 - 290.8) vs 171.7 (IQR 171.7 - 290.8) in the lowest quartile. An area of high IS rate clusters (n=20) was identified in southeastern KY with lower clusters dispersed throughout the state. Figure. Conclusions: This 10-year analysis of IS hospitalizations across KY identified areas of potential intervention. Future efforts are needed to identify the social and medical contributors driving burden of IS in these areas and to design interventions targeted to improve health outcomes.

Unplanned revisits of older patients to the emergency department

IntroductionOlder patients currently represent up to 12%−24% of all emergency department (ED) visits. While increasing in number, they are also at high risk of revisits once discharged. The rate of ED revisits within 72 h is a key indicator of the quality of care in emergency medicine and varies between 1% and 15%. The reasons for ED revisits are natural course of illness, misdiagnosis, lack of homecare, and self-discharge against medical advice. However, the risk factors for ED revisits have not been fully investigated. Therefore, this study aimed to analyze the incidence of ED revisits and identify the risk factors for ED revisits within 72 h after ED discharge.MethodsIn this retrospective study, older patients (≥70 years) were consecutively enrolled if they presented with an Emergency Severity Index of 2 or 3 in a tertiary care ED in 2019, with discharge after the ED visit. The primary endpoint was the frequency of unplanned ED revisits within 72 h after ED discharge. The secondary endpoints were the reasons and potential risk factors for ED revisits. Univariate and multivariate logistic regression models were used.ResultsA total of 592 older patients were enrolled, of whom 30 (5.1%) revisited the ED within 72 h. Gastrointestinal diagnosis [odds ratio (OR), 2.9; 95% confidence interval [CI], 1.04–8.2; p = 0.043) and nausea in particular (OR, 3.5; 95% CI, 1.3–9.4; p = 0.016) were significant risk factors for ED revisits. Furthermore, discharge against medical advice (OR, 5.6; 95% CI, 1.7–18.1; p = 0.004) and ED presentation during the night (OR, 2.7; 95% CI, 1.2–6.1; p = 0.014) were significant risk factors for ED revisits within 72 h after discharge, respectively.ConclusionAlthough the frequency of ED revisits among older patients at 72 h after discharge tends to be low and most revisits were illness-related, all older patients need to be assessed for risk factors for ED revisits. Discharge should be carefully evaluated to improve patient safety and provide the best healthcare to this frail population.

Increasing Follow Up With Primary Care Providers After Emergency Department Visits in Older Adults.

To increase follow up with the primary care team via telephone outreach within 3 days of emergency department (ED) discharge to schedule a follow-up visit within 14 days. Secondary aims included: identifying high utilizers of the ED (defined as more than three ED visits within 6 months), reinforcing discharge instructions from the ED via nursing education on telephone follow ups, and identifying the reasons patients used the ED. Baseline data were gathered retrospectively by reviewing charts of patients discharged from the ED. Charts were reviewed from a biweekly automated report, and RNs initiated follow-up phone calls to patients discharged from the ED, offering appointments and providing pertinent nursing education. Primary care follow ups after ED discharges increased from 38% to 71% over 10 months with the new nurse-led workflow. Patients to whom the RN outreached to were more likely to attend their follow-up appointments. However, a 14-day follow-up appointment with the primary care provider (PCP) showed no significant difference in ED revisits or hospital admissions. Follow up after ED discharge led to increased coordination of care. Nurses provided education about chronic conditions and reiterated discharge instructions that might have been unclear to patients in the ED. Further studies are needed to analyze the effect of follow up with the PCP on ED utilization and hospital admissions. [Journal of Gerontological Nursing, 50(3), 33-39.].

A Nationwide Emergency Department Data Analysis to Predict Beers List Medications Use Among Older Adults

BackgroundThe use of potentially inappropriate medications (PIMs) is considered an important quality indicator for older adults seen in the ambulatory care setting. Study ObjectivesTo evaluate the pattern of potentially inappropriate medication (PIMs) use as specified in the Beers Criteria, for older adults during emergency department (ED) visits in the United States. MethodsUsing data from the National Hospital Ambulatory Care Survey (NHAMCS) we identified older adults (age 65 or older) discharged home from an ED visit in 2019. We defined PIMs as those with an ‘avoid’ recommendation under the American Geriatrics Society (AGS) 2019 Beers Criteria in older adults. Logistic regression models were used to assess demographic, clinical, and hospital factors associated with the use of any PIMs upon ED discharge. ResultsOverall, 5.9% of visits by older adults discharged from the ED included administration or prescriptions for PIMs. Among those who received any PIMs, 25.5% received benzodiazepines, 42.5 % received anticholinergics, 1.4% received nonbenzodiazepine hypnotics, and 0.5% received barbiturates. A multivariable model showed statistically significant associations for age 65 to 74 (OR 1.91, 95% CI 1.39–2.62 vs. age >=75), dementia (OR 0.45, 95% CI 0.21–0.95), lower immediacy (OR 2.45, 95% CI 1.56–3.84 vs. higher immediacy), and Northeastern rural region (OR 0.34, 95% CI 0.21–0.55 vs. Midwestern rural). ConclusionWe found that younger age and lower immediacy were associated with increased prescriptions of PIMs for older adults seen, while dementia and Northeastern rural region was associated with reduced use of PIMs seen and discharged from EDs in United States.

The unnecessary workups and admissions of adolescents and young adults with spontaneous pneumomediastinum

Spontaneous pneumomediastinum (SPM) is a rare condition in children and young adults that raises concern for esophageal perforation or extension of an air leak, resulting in admissions with multiple interventions performed. To assess our outcomes, and to evaluate our resource utilization, we reviewed our experience with SPM. We conducted a retrospective review of SPM cases in patients aged 5–25 years old occurring between 2011 and 2021 at a single academic tertiary care center. Clinical, demographic, and outcome variables were collected and analyzed, and cohorts were compared using Fischer’s Exact Test and Welch’s T Test. 166 SPM cases were identified—all of which were Emergency Department (ED) presentations. 84% of the cases were admitted. 70% had Computerized Tomography (CT) scans, with no defined criteria for imaging. Comparison of floor admissions with discharges from the ED showed no significant difference in presenting symptoms, demographics, or outcomes between the two groups. Recurrence was noted in 4 patients with a range of 5.9 months–4.9 years from the initial episode. In the largest SPM study in the pediatric and young adult population, we noted no significant difference in management or outcomes in admitted or ED discharge patients nor those with CT imaging. Our results suggest that a large number of SPM can be managed safely with discharge from the ED.

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.

Pilot intervention to increase uptake of lung cancer screening through the emergency department

IntroductionThe goal of this study is to demonstrate the feasibility of referring patients for lung cancer screening (LCS) from the emergency department (ED) as a method to increase the uptake of LCS. MethodsThis is a single-arm pilot study at a large safety-net ED. ED LCS-eligible patients were offered a referral to our LCS clinic upon ED discharge. The primary outcome was the frequency at which patients connected with the LCS clinic. ResultsDuring the study period, 105 patients were approached; 26 (24.8%) participated. Reasons for non-enrollment include 29 (27.6%) who were not interested in research, 10 (9.5%) who did not speak English, and 40 (38.1%) who did not meet the pack-years criteria. Seventeen patients (65.4%, 17/26) connected with the LCS clinic, with 10 (38.5%) having been seen in the clinic and received a low dose computed tomography (LDCT) scan. Of the 17 that were connected with the clinic, 7 (26.9%) had a non-LDCT chest CT scan in the past year. Of those that were not seen in the clinic (n = 9), 4 (44.4%) were unreachable via 3 phone calls and a post-marked letter, and 3 (33.3%) did not attend the scheduled appointment, and 2 (22.2%) were delayed due to COVID-19. Of those that had CT scans over the study period (n = 17), 0 scans were normal, one patient (5.9%) had asymptomatic lung cancer, 7 (41.2%) had pulmonary nodules, 11 (64.7%) had emphysema, and 9 (52.9%) had coronary artery disease. ConclusionThis pilot study suggests the feasibility and suggests initial indications of the efficacy of referring ED patients for LCS.

A217 EVALUATING PREDICTIVE SCORING AND OUTCOMES OF PATIENTS DISCHARGED HOME FROM THE EMERGENCY DEPARTMENT WITH UPPER GASTROINTESTINGAL BLEEDING

Abstract Background Upper gastrointestinal bleed (UGIB) is a common emergency department (ED) presentation. The Glasgow-Blatchford Bleeding Score (GBS) is a validated tool for predicting UGIBs requiring admission for endoscopic evaluation. Utilization of GBS in Northern Ontario EDs may help risk stratify UGIB to decrease return to care. Aims This study aimed to evaluate factors and outcomes of patients discharged from the ED with suspected UGIB. Methods A total of 1,139 charts were identified with an ICD-10 ED diagnosis of gastrointestinal hemorrhage from 2016-2022. Of these, 92 charts met inclusion criteria. Patients admitted to hospital from the index ED visit, who were below the age of 18 years at the time of presentation, or with clinically suspected lower gastrointestinal hemorrhage were excluded. Patient were further grouped by place of residence if their primary address was within Thunder Bay city limits or not. Results There were 48 males (52%) with a median age of 58.7 (IQR 32.2) at presentation with UGIB to ED. The median (IQR) Charlson Comorbidity Index (CCI) and GBS were 3 (5) and 3 (6), respectively. The odds ratio for returning to the ED and being admitted for UGIB within sixty days was 4.07 times greater for patients from the region compared to Thunder Bay residents (95% CI 1.28–12.97). GBS was found to be significantly greater (p=0.048, Mann-Whitney U-Test) among seven patients who underwent emergent endoscopy from the ED and were discharged home. In univariate K-M survival analysis, the mean survival time to hospital admission at sixty days was 45 days among those with a presenting GBS score of ampersand:003E3, compared to 57 days when GBS was 3 or less (pampersand:003C0.005, log rank Mantel-Cox). After adjustment for age, sex, place of residence, and CCI, there was a 17% increase in the expected hazard for hospital admission at sixty days for each point increase in GBS (95% CI 1.03–1.34). Similarly, the expected hazard for follow-up hospital admission was 2.95 times higher (95% CI 1.11–7.85) in patients living outside Thunder Bay travelling to seek care. There were no statistically significant hazards identified between age, sex, or CCI and hospital admission (Cox proportional hazards model, p=0.001). Of patients admitted to hospital within sixty days of ED discharge (n=17), the median length of stay was five days with 56% requiring blood transfusion and 83% receiving endoscopy. Conclusions Higher GBS scores and residence outside of Thunder Bay increase the likelihood of revisit and admission to hospital for UGIB following ED discharge. Future research will aim to compare outcomes among larger urban centers. Funding Agencies NOAMA

Emergency Department Volume and Delayed Diagnosis of Serious Pediatric Conditions

Diagnostic delays are common in the emergency department (ED) and may predispose to worse outcomes. To evaluate the association of annual pediatric volume in the ED with delayed diagnosis. This retrospective cohort study included all children younger than 18 years treated at 954 EDs in 8 states with a first-time diagnosis of any of 23 acute, serious conditions: bacterial meningitis, compartment syndrome, complicated pneumonia, craniospinal abscess, deep neck infection, ectopic pregnancy, encephalitis, intussusception, Kawasaki disease, mastoiditis, myocarditis, necrotizing fasciitis, nontraumatic intracranial hemorrhage, orbital cellulitis, osteomyelitis, ovarian torsion, pulmonary embolism, pyloric stenosis, septic arthritis, sinus venous thrombosis, slipped capital femoral epiphysis, stroke, or testicular torsion. Patients were identified using the Healthcare Cost and Utilization Project State ED and Inpatient Databases. Data were collected from January 2015 to December 2019, and data were analyzed from July to December 2023. Annual volume of children at the first ED visited. Possible delayed diagnosis, defined as a patient with an ED discharge within 7 days prior to diagnosis. A secondary outcome was condition-specific complications. Rates of possible delayed diagnosis and complications were determined. The association of volume with delayed diagnosis across conditions was evaluated using conditional logistic regression matching on condition, age, and medical complexity. Condition-specific volume-delay associations were tested using hierarchical logistic models with log volume as the exposure, adjusting for age, sex, payer, medical complexity, and hospital urbanicity. The association of delayed diagnosis with complications by condition was then examined using logistic regressions. Of 58 998 included children, 37 211 (63.1%) were male, and the mean (SD) age was 7.1 (5.8) years. A total of 6709 (11.4%) had a complex chronic condition. Delayed diagnosis occurred in 9296 (15.8%; 95% CI, 15.5-16.1). Each 2-fold increase in annual pediatric volume was associated with a 26.7% (95% CI, 22.5-30.7) decrease in possible delayed diagnosis. For 21 of 23 conditions (all except ectopic pregnancy and sinus venous thrombosis), there were decreased rates of possible delayed diagnosis with increasing ED volume. Condition-specific complications were 11.2% (95% CI, 3.1-20.0) more likely among patients with a possible delayed diagnosis compared with those without. EDs with fewer pediatric encounters had more possible delayed diagnoses across 23 serious conditions. Tools to support timely diagnosis in low-volume EDs are needed.
