Association between initial antibiotic route and outcomes for children hospitalized with pneumonia.

Initial oral antibiotics may be as effective as intravenous (IV) antibiotics for children hospitalized with community-acquired pneumonia (CAP), but further data are needed. We evaluated for associations of initial antibiotic route (IV vs. oral) with length of stay (LOS) and secondary outcomes for children hospitalized with CAP. This multicenter, retrospective cohort study included children with CAP who were hospitalized for >48 h, had chest radiographs, and received antibiotics at four children's hospitals between 2014 and 2020. Data were obtained from the Pediatric Health Information System and manual chart review. The exposure was initial antibiotic route (i.e., first antibiotic given intravenously or orally). We performed multivariable regression modeling using inverse probability treatment weights from propensity scores. Outcomes included LOS, oxygen duration, cost, care escalation, and readmission or emergency department revisit. Of 1147 included children, 37% received initial oral antibiotics. Within the propensity balanced sample, LOS was 73.5 h (IQR 61.0, 99.5) and 78.7 (61.0, 118.0) for patients with initial oral and IV antibiotics, respectively. Children receiving initial oral antibiotics had an 8% reduction in LOS (OR 0.92 [95% CI: 0.87, 0.94]) and 14% reduction in cost (OR 0.86 [95% CI 0.79, 0.94]) versus those receiving initial IV antibiotics. There were no differences in other outcomes. Children with CAP receiving initial oral antibiotics had reduced LOS and hospital cost without differences in escalated care or return visits. Starting hospitalized children on oral antibiotics is likely a safe and effective alternative to IV treatment.

Low-Risk Chest Pain Patients: Exploring the Impact of Socioeconomy on Emergency Department Revisits

BackgroundPatients with chest pain and undetectable high-sensitivity cardiac troponin T (hs-cTnT) in the emergency department (ED) have a low short-term risk of cardiovascular events, but the frequency of ED revisits in this group is unknown. This study investigated the associations between disposable income and risk of ED revisits in patients with chest pain and undetectable hs-cTnT. MethodsAll first visits to 7 EDs in Sweden from 2010 to 2017 by patients with chest pain and hs-cTnT <5 ng/l were included. Incidence rate ratios (IRR) were calculated to estimate the ED revisit risk in relation to disposable income according to data obtained from Swedish government agencies (Statistics Sweden). ResultsAltogether, 61,539 patients with a first ED visit were included, in whom 126,650 revisits occurred. The adjusted 30-day risk of a revisit was 1.3- (IRR 1.32, 95% CI: 1.23-1.42) and 1.5-fold (IRR 1.50, 95% CI: 1.40-1.60), and for any revisit during the follow-up 1.6- (IRR 1.63, 95% CI: 1.59-1.66) and 1.8-fold (IRR 1.78, 95% CI 1.72-1.79), in patients with middle-low and low versus high income, respectively. During a median follow-up of 6.8 years, 1714 (2.8%) deaths occurred, and the adjusted cumulative incidence of major adverse cardiovascular events at 1 and 5 years was only 0.3% (95% CI: 0.2-0.4%) and 1.1% (95% CI: 0.8-1.4%) higher in patients with the lowest versus highest income levels. ConclusionsDisposable income level is inversely associated with the risk of ED revisits among patients presenting with chest pain and undetectable hs-cTnT, in whom cardiovascular risks are low.

Systematic Review and Meta-Analysis of Diagnostic and Predictive Accuracy of the Clinical Frailty Scale in Older Adults in Emergency Department

Abstract Background Older adults attending the Emergency Department (ED) should be assessed using a frailty screening tool as older adults living with frailty are more likely to experience adverse outcomes. The Clinical Frailty Scale (CFS) is commonly used for this. This systematic review and meta-analysis synthesise the literature studying predictive accuracy of the CFS for identifying older adults at risk of adverse outcomes following ED visit, and the diagnostic accuracy of the CFS for identifying older adults living with frailty attending the ED. Methods A systematic literature search was conducted to identify studies that attempted to validate the diagnostic and predictive accuracy of the CFS for older adults in the ED setting. The population included were older adults over 65 years of age who presented to the ED with undifferentiated medical complaints. All included studies assessed the diagnostic accuracy of the CFS in comparison to a reference standard: Frailty Index, Comprehensive Geriatric Assessment or Frailty Phenotype. The adverse outcomes included were mortality, falls, functional decline, ED re-attendance, hospital admission, length of stay and institutionalisation. Results Nineteen studies were included with sixteen individual cohorts. All studies investigated predictive accuracy and four studies assessed diagnostic accuracy for the CFS. The CFS showed predictive accuracy for the outcomes of mortality at all timepoints (RR 3.05 (CI 2.22, 4.21)), ED re-attendance at 30 days (RR 1.47 (CI 1.12, 1.94)), hospital admission at index visit (RR 1.72 (CI 1.26, 2.34) and institutionalisation (RR 3.63 (CI 1.41, 9.36). The studies included had an overall low risk of bias. Conclusion The CFS successfully identifies those at risk of adverse outcomes of death, ED revisit, hospitalisation and institutionalisation. However, there is a paucity of studies which assess its diagnostic accuracy. Overall, it is a useful screening tool to identify those who may benefit from comprehensive multidisciplinary assessment in the ED setting.

Caregivers' burden of care during emergency department care transitions among older adults: a mixed methods cohort study.

Improving care transitions for older adults can reduce emergency department (ED) revisits, and the strain placed upon caregivers. We analyzed whether caregivers felt a change in burden following a care transition, and what may be improved to reduce it. This mixed-methods observational study nested within LEARNING WISDOM included caregivers of older patients who experienced an ED care transition. Burden was collected with the brief Zarit Burden Interview (ZBI-12), and caregivers also commented on the care transition. A qualitative coding scheme of patient care transitions was created to reflect themes important to caregivers. Comments were randomly analyzed until saturation and themes were extracted from the data. We followed both the SRQR and STROBE checklists. Comments from 581 caregivers (mean age (SD) 64.5 (12.3), 68% women) caring for patients (mean age (SD) 77.2 (7.54), 48% women) were analyzed. Caregivers overwhelmingly reported dissatisfaction and unmet service expectations, particularly with home care and domestic help. Communication and follow-up from the ED emerged as an area for improvement. Caregivers who reported an increased level of burden following a patient's care transition had significantly higher ZBI scores than caregivers who self-reported stable burden levels. Caregivers with increasing, stable, and improved levels of subjective burden all reported areas for improvement in the care transition process. Themes centering on the capacity to live at home and inadequate communication were most frequently mentioned and may represent serious challenges to caregivers. Addressing these challenges could improve both caregiver burden and ED care transitions.

Hospitalization and Health Resource Utilization in Emergency Department Cases of Diabetic Foot Infections in the U.S. from 2012 to 2021: A Nationally Representative Analysis.

Objectives: The objective of this paper was to assess hospitalizations and health resource utilization associated with diabetic foot infection (DFI)-related visits within emergency departments (EDs) in the U.S. Methods: This nationally representative, cross-sectional historical cohort utilized the Centers for Disease Control and Prevention's (CDC's) National Hospital Ambulatory Medical Care Survey across a ten-year period from 2012 to 2021. Inclusion criteria were as follows: adults ≥18 years of age; a diagnosis of Type 1 or Type 2 diabetes mellitus; presence of a DFI. Comparisons were drawn relative to a cohort of patients with diabetes without foot complications. Study outcomes included 72-hour (72 h) ED revisit, hospitalization, and length of stay (LOS). Top diagnoses and medications were also reported. Multivariable, generalized, linear regression analyses were employed, controlling for key demographics, health system factors, clinical characteristics, and year. Results: An estimated 150.6 million ED visits included a diabetes diagnosis, with 2.4 million involving a DFI (1.6%). Approximately half of DFI cases were hospitalized (43.7%). Anti-infective medications were prescribed in 83.1% of DFI cases, including vancomycin in 28.1%. Multivariable analyses observed that DFIs were associated with a 3.002 times higher odds of hospital admissions (CI: 2.145-4.203, p < 0.001) and a 55.0% longer LOS (IR = 1.550, CI: 1.241-1.936, p < 0.001). DFIs were not significantly associated with a 72 h ED revisit. Conclusions: This nationally representative study of 2.4 million DFI-related ED visits in the U.S. observed higher odds of hospital admissions and a longer LOS for DFIs versus diabetes without foot complications. Continued research should seek to assess prevention and coordinated treatment interventions prior to the emergence of DFIs requiring ED care.

Languages other than English in a pediatric ED: Documentation, extended stays, and revisits

ObjectiveGiven the increasing proportion of patients and caregivers who use languages other than English (LOE) at our institution and across the U.S, we evaluated key workflow and outcome measures in our emergency department (ED) for patients and caregivers who use LOE. MethodsThis was a retrospective, cross-sectional study of patients and caregivers who presented to a free-standing urban pediatric facility. We used electronic health record data (EHR) and interpreter usage log data for our analysis of language documentation, length of stay, and ED revisits. We assessed ED revisits within 72-h using a multivariable logistic regression model adjusting for whether a primary care provider (PCP) was listed in the EHR, whether discharge was close to or on the weekend, and insurance status. We restricted our analysis to low-acuity patient encounters (Emergency Severity Index (ESI) scores of 4 and 5) to limit confounding factors related to higher ESI scores. ResultsWe found that one in five patients and caregivers who use LOE had incorrect documentation of their language needs in the EHR. Using interpreter usage data to most accurately capture encounters using LOE, we found that patient encounters using LOE had a 38-min longer length of stay (LOS) and twice the odds of a 72-h ED revisit compared to encounters using English. ConclusionThese results highlight the need for better language documentation and understanding of factors contributing to extended stays and increased revisits for pediatric patients and caregivers who use LOE.

Health care utilization of patients with acute abdominal pain before and after emergency department visits

BackgroundAcute abdominal pain (AAP) is a major driver for capacity-use in emergency departments (EDs) worldwide. Yet, the health care utilization of patients with AAP before and after the ED remains unclear. The primary objective of this study was to describe adult patients presenting to the ED with AAP and their outpatient care (OC) use before and after the ED. Secondary objectives included description of hospitalization rates, in-hospital mortality, ED re-visits, and exploration of potential risk factors for hospitalization and ED re-visits.MethodsFor the analysis, we combined routine hospital data from patients who visited 15 EDs in Germany in 2016 with their statutory health insurance OC claims data from 2014 to 2017. Adult patients were included based on a chief complaint or an ED diagnosis indicating unspecific AAP or the Manchester Triage System indicator “Abdominal pain in adults”. Baseline characteristics, ED diagnosis, frequency and reason of hospitalization, frequency and type of prior-OC (prOC) use up to 3 days before and of post-OC use up to 30 days after the ED visit.Main resultsWe identified 28,085 adults aged ≥ 20 years with AAP. 39.8% were hospitalized, 33.9% sought prOC before the ED visit (48.6% of them were hospitalized) and 62.7% sought post-OC up to 30 days after the ED visit. Hospitalization was significantly more likely for elderly patients (aged 65 and above vs. younger; adjusted OR 3.05 [95% CI 2.87; 3.25]), prOC users (1.71 [1.61; 1.90]) and men (1.44 [1.37; 1.52]). In-hospital mortality rate was 3.1% overall. Re-visiting the ED within 30 days was more likely for elderly patients (1.32 [1.13; 1.55) and less likely for those with prOC use (0.37 [0.31; 0.44]).ConclusionsprOC use was associated with more frequent hospitalizations but fewer ED re-visits. ED visits by prOC patients without subsequent hospitalization may indicate difficulties of OC resources to meet the complex diagnostic requirements and expectations of this patient population. Fewer ED re-visits in prOC users indicate effective care in this subgroup.

An emergency department transitional care team prevents unnecessary hospitalization of older adults: a mixed methods study.

Older adults with acute functional decline may visit emergency departments (EDs) for medical support despite a lack of strict medical urgency. The introduction of transitional care teams (TCT) at the ED has shown promise in reducing avoidable admittances. However, the optimal composition and implementation of TCTs are still poorly defined. We evaluated the effect of TCTs consisting of an elderly care physician (ECP) and transfer nurse versus a transfer nurse only on reducing hospital admissions, as well as the experience of patients and caregivers regarding quality of care. We assessed older adults (≥ 65 years) at the ED with acute functional decline but no medical indication for admission. Data were collected on type and post-ED care, and re-visits were evaluated over a 30-day follow-up period. Semi-structured interviews with stakeholders were based on the Consolidated-Framework-for-Implementation-Research, while patient and caregiver experiences were collected through open-ended interviews. Among older adults (N = 821) evaluated by the TCT, ECP and transfer nurse prevented unnecessary hospitalization at the same rate (81.2%) versus a transfer nurse alone (79.5%). ED re-visits were 15.6% (ECP and transfer nurse) versus 13.5%. The interviews highlighted the added value of an ECP, which consisted of better staff awareness, knowledge transfer and networking with external organizations. The TCT intervention in general was broadly supported, but adaptability was regarded as an important prerequisite. Regardless of composition, a TCT can prevent unnecessary hospitalization of older adults without increasing ED re-visiting rates, while the addition of an ECP has a favourable impact on patient and professional experiences.

Characterizing Acute Pulmonary Embolism Cases Diagnosed at an Emergency Department Revisit Using a Statewide Clinical Registry

To assess the rate and characteristics of acute pulmonary embolism (PE) cases diagnosed in the emergency department (ED) following an ED discharge visit within 10 days. This is a retrospective analysis of 40 EDs in a statewide clinical registry from 2017 to 2022. We identified adult patients with acute PEs diagnosed in the ED. We assessed PE cases wherein a prior ED visit for the same patient resulting in discharge had taken place within 10 days without interval hospitalization. We then characterized the overall rate of revisit PE cases per overall acute PE cases and per 10,000 ED discharges. We also reported on subgroups of revisit cases where the preceding visit resulted in diagnosis of COVID-19, other cardiopulmonary conditions, and cardiopulmonary symptom codes (eg, chest pain, unspecified). Of 24,525 acute PEs, 1,202 (4.9%, 95% confidence interval [CI] 4.6% to 5.2%) had an ED discharge within the preceding 10 days (2.0 per 10,000 ED discharges, 95% CI 1.9 to 2.1). Two hundred thirty-three (19.4%) were originally discharged with a COVID-19 diagnosis, 107 (8.9%) were originally discharged with another cardiopulmonary condition, and 201 (16.7%) were cases discharged with a nonspecific cardiopulmonary symptom code. Discharges with diagnoses of COVID-19, pneumonia, and pleural effusion had higher rates of revisits with acute PE. In this retrospective analysis, about 1 in 20 acute PEs and 2 in 10,000 ED discharges were associated with an ED revisit for acute PE. Some cases may represent potential diagnostic opportunities, whereas others may be progression of disease, risk factors for PE, or unrelated.

Emergency department 30-Day emergency department revisits among people with sickle cell disease: Variations in characteristics.

People with sickle cell disease (SCD) often have emergency department (ED) revisits. The characteristics of people with SCD with ED revisits were assessed in this study using Medicaid administrative claims data from California and Georgia, representing 2794 and 3641 individuals with SCD, respectively. In both states, those with 6+ primary care provider (PCP) encounters had the highest percentage of ED revisits. In California, those with 6+ hematology encounters had the lowest percentage of individuals with an ED revisit; in Georgia, those with 1-2 hematology encounters. Increasing access to hematologic care may reduce ED revisits among people with SCD.

Neutrophil-to-lymphocyte ratio as a predictor for outcomes in patients with short-term emergency department revisits.

Analysis of short-term emergency department (ED) revisits is a common emergency care quality assurance practice. Previous studies have explored various risk factors of ED revisits; however, laboratory data were usually omitted. This study aimed to evaluate the prognostic significance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte (PLR), and systemic immune-inflammation index (SII) in predicting outcomes of patients revisiting the ED. This retrospective observational cohort study investigated short-term ED revisit patients. The primary outcome measure was high-risk ED revisit, a composite of in-hospital mortality or intensive care unit (ICU) admission after 72-hour ED revisit. The NLR, PLR, and SII were investigated as potential prognostic predictors of ED revisit outcomes. A total of 1916 encounters with short-term ED revisit patients were included in the study; among these, 132 (6.9%) encounters, comprising 57 in-hospital mortalities and 95 ICU admissions, were high-risk revisits. High-risk revisit patients had significantly higher NLR, PLR, and SII (11.6 vs 6.6, p < 0.001; 26.2 vs 18.9, p = 0.004; 2209 vs 1486, p = 0.002, respectively). Multiple regression analysis revealed revisit-NLR as an independent factor for predicting poor outcomes post-ED revisits (odds ratio: 1.031, 95% CI: 1.017-1.045, p < 0.001); an optimal cut-off value of 7.9 was proven for predicting high-risk ED revisit. The intensity of the inflammatory response expressed by NLR was an independent predictor for poor outcomes of ED revisits and should be considered when ED revisits occur. Future prediction models for ED revisit outcomes can include revisit-NLR as a potential predictor to reflect the progressive conditions in ED patients.

What Makes Effective Acute Geriatric Care? - A mixed Methods Study From Aotearoa New Zealand

Structured Objectives Current policies for older patients do not adequately address the barriers to effective implementation of optimal care models in New Zealand, partly due to differences in patient definitions and the in-patient pathway they should follow through hospital. This research aims to: (a) synthesise a definition of a complex older patient; (b) identify and explore primary and secondary health measures; and (c) identify the primary components of a care model suitable for a tertiary hospital in the midland region of the North Island of New Zealand.MethodThis mixed-methods study utilised a convergence model, in which qualitative and quantitative data were investigated separately and then combined for interpretation. Semi-structured interviews (n=11) were analysed using a general inductive method of enquiry to develop key codes, categories and themes. Univariate data analysis was employed using six years of routinely collected data of patients admitted to the emergency department and inpatient units (n=261,773) of the tertiary hospital.ResultsA definition of a complex older patient was determined that incorporates chronic conditions, comorbidities and iatrogenic complications, functional decline, activities of daily living, case fatality, mortality, hospital length of stay, hospital costs, discharge destination, hospital readmission and emergency department revisit and age – not necessarily over 65 years old. Well-performing geriatric care models were found to include patient-centred care, frequent medical review, early rehabilitation, early discharge planning, a prepared environment and multidisciplinary teams.ConclusionsThe findings of this New Zealand study increase understanding of acute geriatric care for complex older patients by filling a gap in policies and strategies, identifying potential components of an optimal care model and defining a complex geriatric patient.Implications for Public HealthThe findings of this study present actionable opportunities for clinicians, managers, academics and policymakers to better understand a complex older patient in New Zealand, with significant relevance also for international geriatric care and to establish an effective acute geriatric care model that leads to beneficial health outcomes and provides safeguard mechanisms.

ABCD2-I Score Predicts Unplanned Emergency Department Revisits within 72 Hours Due to Recurrent Acute Ischemic Stroke.

the ABCD2 score is valuable for predicting early stroke recurrence after a transient ischemic attack (TIA), and Doppler ultrasound can aid in expediting stroke triage. The study aimed to investigate whether combining the ABCD2 score with carotid duplex results can enhance the identification of early acute ischemic stroke after TIA. we employed a retrospective cohort design for this study, enrolling patients diagnosed with TIA who were discharged from the emergency department (ED). The modified ABCD2-I (c50) score, which incorporates a Doppler ultrasound assessment of internal carotid artery stenosis > 50%, was used to evaluate the risk of acute ischemic stroke within 72 h. Patients were categorized into three risk groups: low risk (with ABCD2 and ABCD2-I scores = 0-4), moderate risk (ABCD2 score = 4-5 and ABCD2-I score = 5-7), and high risk (ABCD2 score = 6-7 and ABCD2-I score = 8-9). between 1 January 2014, and 31 December 2019, 1124 patients with new neurological deficits were screened, with 151 TIA patients discharged from the ED and included in the analysis. Cox proportional hazards analysis showed that patients in the high-risk group, as per the ABCD2-I (c50) score, were significantly associated with revisiting the ED within 72 h due to acute ischemic stroke (HR: 3.12, 95% CI: 1.31-7.41, p = 0.0102), while the ABCD2 alone did not show significant association (HR: 1.12, 95% CI: 0.57-2.22, p = 0.7427). ABCD2-I (c50) scores effectively predict early acute ischemic stroke presentations to the ED within 72 h after TIA.

Can I Discharge This Adult Patient with Abnormal Vital Signs From the Emergency Department?

BackgroundVital signs are an essential component of the emergency department (ED) assessment. Vital sign abnormalities are associated with adverse events in the ED setting and may indicate a risk of poor outcomes after ED discharge. Clinical questionWhat is the risk of adverse events among adult patients with abnormal vital signs at the time of ED discharge? Evidence reviewStudies retrieved included 6 retrospective studies with adult patients discharged from the ED. These studies evaluated adverse outcomes in adult patients discharged from the ED with abnormal vital signs. Hypotension at discharge was associated with the highest odds of adverse events after discharge. Tachycardia was also a key predictor of adverse events after discharge and may be easily missed by ED clinicians. ConclusionBased on the available evidence, the specific vital sign abnormality and the number of total abnormalities influence the risk of adverse outcomes after discharge. Vital sign abnormalities at the time of discharge also increase the risk of ED revisit. The most common abnormal vital sign at the time of discharge is tachycardia.

Lactate Levels as a Predictor of Emergency Department Revisits in Infants With Acute Bronchiolitis.

This study aimed to identify predictive biomarkers for unscheduled emergency department (ED) revisits within 24 hours of discharge in infants diagnosed with acute bronchiolitis (AB). A retrospective observational study was conducted on infants diagnosed with AB who visited 3 emergency medical centers between January 2020 and December 2022. The study excluded infants with comorbidities, congenital diseases, and prematurity and infants who revisited the ED after 24 hours of discharge. Demographic data, vital signs, and laboratory results were collected from the medical records. Univariable and multivariable logistic regression analyses were performed on factors with P of less than 0.1 in univariable analysis. Receiver operator curve analysis was used to assess the accuracy of lactate measurements in predicting ED revisits within 24 hours of discharge. Out of 172 participants, 100 were in the revisit group and 72 in the discharge group. The revisit group was significantly younger and exhibited higher lactate levels, lower pH values, and higher pCO 2 levels compared to the discharge group. Univariable logistic regression identified several factors associated with revisits. Multivariable analysis found that only lactate was a variable correlated with predicting ED revisits (odds ratio, 18.020; 95% confidence interval [CI], 5.764-56.334). The receiver operator curve analysis showed an area under the curve of 0.856, with an optimal lactate cutoff value of 2.15. Lactate value in infants diagnosed with AB were identified as a potential indicator of predicting unscheduled ED revisits within 24 hours of discharge. The predictive potential of lactate levels holds promise for enhancing prognosis prediction, reducing health care costs, and alleviating ED overcrowding. However, given the study's limitations, a more comprehensive prospective investigation is recommended to validate these findings.

Antibiotic route and outcomes for children hospitalized with pneumonia.

Emerging evidence suggests that initial oral and intravenous (IV) antibiotics have similar efficacy in pediatric community-acquired pneumonia (CAP), but further data are needed. We determined the association between hospital-level initial oral antibiotic rates and outcomes in pediatric CAP. This retrospective cohort study included children hospitalized with CAP at 43 hospitals in the Pediatric Health Information System (2016-2022). Hospitals were grouped by whether initial antibiotics were given orally in a high, moderate, or low proportion of patients. Regression models examined associations between high versus low oral-utilizing hospitals and length of stay (LOS, primary outcome), intensive care unit (ICU) transfers, escalated respiratory care, complicated CAP, cost, readmissions, and emergency department (ED) revisits. Initial oral antibiotics were used in 16% (interquartile range: 10%-20%) of 30,207 encounters, ranging from 1% to 68% across hospitals. Comparing high versus low oral-utilizing hospitals (oral rate: 32% [27%-47%] and 10% [9%-11%], respectively), there were no differences in LOS, intensive care unit, complicated CAP, cost, or ED revisits. Escalated respiratory care occurred in 1.3% and 0.5% of high and low oral-utilizing hospitals, respectively (relative ratio [RR]: 2.96 [1.12, 7.81]), and readmissions occurred in 1.5% and 0.8% (RR: 1.68 [1.31, 2.17]). Initial oral antibiotics varied across hospitals without a difference in LOS. While high oral-utilizing hospitals had higher escalated respiratory care and readmission rates, these were rare, the clinical significance of these small differences is uncertain, and there were no differences in other clinically relevant outcomes. This suggests some children may benefit from initial IV antibiotics, but most would probably do well with oral antibiotics.

Prediction of high-risk emergency department revisits from a machine-learning algorithm: a proof-of-concept study

BackgroundHigh-risk emergency department (ED) revisit is considered an important quality indicator that may reflect an increase in complications and medical burden. However, because of its multidimensional and highly complex nature,...

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.
