Quality of care and emergency department throughput during the COVID-19 pandemic in a community health system Pandemic in a Community Health System

Objective: This retrospective study explores the strategic plan formulated by AHMC Health System in California, USA, to sustain and improve quality of care and emergency department (ED) efficiency during the COVID-19 pandemic. It also analyzes the plan’s outcomes.Background: The COVID-19 pandemic has posed challenges for both individuals and healthcare industries alike, impacting decision-making and access to care. AHMC faced staff and resource shortages, patient reluctance, and difficulties adapting to rapidly evolving public health guidelines. These challenges highlighted the critical need for effective plans to maintain or improve healthcare quality and ED performance.Methods: AHMC adopted a comprehensive three-layer strategic plan in 2020. The first layer, “Pandemic Response,” focused on leadership, staff training and education, infection control, new treatments, and employee vaccination rates. The second layer, “ED Throughput,” set objectives for metrics such as door-to-doctor (door-to-doc) time, ancillary turnaround time (TAT), ED length of stay (LOS), and the left-without-being-seen (LWBS) rates. Progress was monitored through monthly improvement meetings. The third layer, “Quality Excellence,” tracked improvements in COVID-adapted objectives on quality initiatives, based on CMS Quality Star Ratings, Leapfrog Hospital Safety Grades, and Yelp review scores.Results: By 2023, the three-layer strategic plan had led to many improvements in the quality of care and ED efficiency. AHMC identified 22,287 positive COVID-19 cases, expanded its ventilator inventory by 50%, and enhanced patient outcomes by applying updated treatments. Additionally, AHMC saw a 3% reduction in ED wait times and sustained its overall patient satisfaction rates, CMS Quality Star Rating, and Leapfrog Hospital Safety Grade scores.Conclusions: AHMC’s three-layer strategic plan showed effectiveness in maintaining quality of care and ED efficiency during the COVID-19 pandemic. By focusing on “Pandemic Response,” “ED Throughput,” and “Quality Excellence,” AHMC was able to adapt to the rapidly evolving public health guidelines, expand its capacity to treat COVID-19 patients and sustain its overall patient safety, satisfaction, and quality ratings. The implementation of this plan highlights the importance of proactive and comprehensive strategies in managing healthcare crises.

Imaging in a Pandemic: How Lack of Intravenous Contrast for Computed Tomography Affects Emergency Department Throughput.

During the coronavirus 2019 pandemic, hospitals in the United States experienced a shortage of contrast agent, much of which is manufactured in China. As a result, there was a significantly decreased amount of intravenous (IV) contrast available. We sought to determine the effect of restricting the use of IV contrast on emergency department (ED) length of stay (LOS). We conducted a single-institution, retrospective cohort study on adult patients presenting with abdominal pain to the ED from March 7-July 5, 2022. Of 26,122 patient encounters reviewed, 3,028 (11.6%) included abdominopelvic CT with a complaint including "abdominal pain." We excluded patients with outside imaging and non-ED scans. Routine IV contrast agent was administered to approximately 74.6% of patients between March 7-May 6, 2022, when we altered usage guidelines due to a nationwide shortage. Between May 6-July 5, 2022, 32.8% of patients received IV contrast after institutional recommendations were made to limit contrast use. We compared patient demographics and clinical characteristics between groups with chi-square test for frequency data. We analyzed ED LOS with nonparametric Wilcoxon rank-sum test for continuous measures with focus before and after new ED protocols. We also used statistical process control charts and plotted the 1, 2 and 3 sigma control limits to visualize the variation in ED LOS over time. The charts include the average (mean) of the data and upper and lower control limits, corresponding to the number of standard deviations away from the mean. After use of routine IV contrast was discontinued, ED LOS (229.0 vs 212.5 minutes, P = <0.001) declined by 16.5 minutes (95% confidence interval -10, -22). Intravenous contrast adds significantly to ED LOS. Decreased use of routine IV contrast in the ED accelerates time to CT completion. A policy change to limit IV contrast during a national shortage significantly decreased ED LOS.

The Impact of Involving a Senior Emergency Physician in the Triage Process

BACKGROUND: Emergency Department (ED) overcrowding has been demonstrated in several studies to be associated with undesirable effects such as longer waiting times, reduced patient satisfaction, and, most importantly, poor patient outcomes. Furthermore, long waiting times for walk-ins result in more complaints and patient dissatisfaction than illness management itself, with the majority of issues arising as a result of real and perceived waiting periods before being seen by the doctor. AIM: We set out to investigate whether introducing a senior emergency physician into the triage system would reduce waiting time, door-to-decision time, and door-to-doctor time, as well as increase patient satisfaction across the ED. METHOD: This was an interventional pre-post study that utilised retrospective data to evaluate the effect on ED throughput of triage by senior emergency physicians. We aimed to measure its impact on waiting time, door-to-decision time, and door-to-doctor time, along with ED patient satisfaction. RESULTS: Patient satisfaction, the overall assessment of treatment received during the visit, increased, from 74.975 to 77.425, and the likelihood of patients recommending the ED increased from 71.36 to 75.21. Operational metrics revealed a considerable drop in door-to-decision time (admit or discharge) of 46 minutes and 3 seconds, as well as a 1 minute and 21 second reduction in time from door to doctor (arrival to first provider). CONCLUSION: The mixed results hint at an effective but iterative process of enhancing patient flow and experience in the ED through senior physician triage.

Is boarding compromising our residents' education? A national survey of emergency medicine program directors.

Boarding patients in the emergency department (ED) potentially affects resident education. Program director (PD) perceptions of the impact of boarding on their trainees have not been previously described. We surveyed a cross-sectional convenience sample of emergency medicine PDs using a mixed-methods approach to explore their perceptions of how boarding has affected their residents' training. Descriptive data were reported as percentages and differences were calculated using Pearson's chi-square test, with p < 0.05 considered significant. A framework model was used to qualitatively analyze free-text responses. A total of 170 responses were collected, for a response rate of 63%. Most respondents felt that boarding had at least some effect on resident education with 29%, 35%, 18%, and 12% noting "a little," "a moderate amount," "a lot," and "a great deal," respectively, and 5% noting "no effect at all." Respondents perceived a negative impact of boarding on resident education and training, with 80% reporting a "somewhat" or "extremely negative" effect, 18% feeling neutral, and 2% noting a "somewhat positive" effect. Most noted a "somewhat" or "extremely negative" effect on resident education in managing ED throughput (70%) and high patient volumes (66%). Fifty-four percent noted a "somewhat" or "extremely negative" impact on being involved in the initial workup of undifferentiated patients. Thirty-two percent saw a "somewhat" or "extremely positive" effect on learning the management of critically ill patients. Qualitative analysis of challenges, mitigation strategies, and resident feedback emphasized the lack of exposure to managing departmental patient flow, impact on bedside teaching, and need for flexibility in resident staffing. Most PDs agree that boarding negatively affects resident education and identify several strategies to mitigate the impact. These findings can help inform future interventions to optimize resident learning in the complex educational landscape of high ED boarding.

Impacts of the 2021 heat dome on emergency department visits, hospitalizations, and health system operations in three hospitals in Seattle, Washington.

Extreme heat events (EHEs) are associated with excess healthcare utilization but specific impacts on emergency department (ED) operations and throughput are unknown. In 2021, the Pacific Northwest experienced an unprecedented heat dome that resulted in substantial regional morbidity and mortality. The aim of this study was to examine its impact on ED utilization, unplanned hospitalization, and hospital operations in a large academic healthcare system. Retrospective electronic medical records from three Seattle-area hospitals were used to compare healthcare utilization during the EHE compared to a pre-event reference period within the same month. Interrupted time series analysis was used to evaluate the association between EHE exposure and ED visits and hospitalizations. Metrics of ED crowding for the EHE were compared to the reference period using Student's t-tests and chi-squared tests. Additionally, multivariable Poisson regression was used to identify risk factors for heat-related illness and hospital admission. Interrupted time series analysis showed an increase of 21.7 ED visits per day (95% confidence interval [CI]=14.7, 28.6) and 9.9 unplanned hospitalizations per day (95% CI=8.3, 11.5) during the EHE, as compared to the reference period. ED crowding and process measures also displayed significant increases, becoming the most pronounced by day 3 of the EHE; the EHE was associated with delays in ED length of stay of 1.0h (95% CI=0.4, 1.6) compared to the reference period. Higher incidence rate ratios for heat-related illness were observed for patients who were older (incidence rate ratio [IRR]=1.02; 95% CI=1.01,1.03), female (IRR=1.47; 95% CI=1.06, 2.04), or who had pre-existing diabetes (IRR=3.19; 95% CI=1.47, 6.94). The 2021 heat dome was associated with a significant increase in healthcare utilization including ED visits and unplanned hospitalizations. Substantial impacts on ED and hospital throughput were also noted. These findings contribute to the understanding of the role extreme heat events play on impacting patient outcomes and healthcare system function.

Emergency Department Overcrowding: An Environmental Scan of Contributing Factors and a Summary of Systematic Review Evidence on Interventions

&#x0D; Emergency department (ED) overcrowding occurs when the demand for health services in the ED exceeds the capacity of the ED, hospital, or community to deliver quality care in a reasonable amount of time. Overcrowding is worsening in jurisdictions across Canada and there is a need to address its many causes and identify potential solutions.&#x0D; This report uses a modified version of a conceptual model developed by Asplin et al. (2003) that organizes the emergency care system into 3 interdependent parts: input (arrival to the ED), throughput (flowing through the ED), and output (leaving the ED). We also examined an additional fourth part related to contextual factors and systems that affect overcrowding but lay outside of input, throughout, and output.&#x0D; &#x0D; Examples of factors include, but are not limited to, increased complexity of needs (input), diagnostic testing and procedures (throughput), boarding (output), and limited resources for mental health and substance use (outside the ED).&#x0D; Examples of interventions that were effective in some settings include, but are not limited to, prehospital decision-making by first responders, which reduced ED visits (input); short stay crisis units for people experiencing mental health challenges, which improved emergency department length of stay, wait times, boarding, and patient safety (throughput); ED-based discharge planning, which reduced ED return visits (output); and time-based policy reforms, which reduced ED length of stay (outside the ED).&#x0D; &#x0D; &#x0D; Most of the factors we identified in the published literature existed either outside of the ED or at the interface of the ED and other health care services (input and output), whereas most of the interventions we identified existed within the ED (throughput).&#x0D; We heard from participants (during multistakeholder dialogue sessions) and content experts that ED overcrowding is a complex health system issue for which the causes, impacts, and solutions extend beyond the ED. Specifically, the novel insights we heard included:&#x0D; &#x0D; ED overcrowding is better viewed as a problem of hospital overcrowding and strained resources in the broader social and health care systems. Contributing factors both within and outside the ED influence and interact with each other and are affected by economic, cultural, and institutional realities.&#x0D; Solving the issue requires addressing accountability and implementing multifaceted solutions in which several systems and voices work collaboratively.&#x0D; Existing technologies and data use and collection are not being used to their full potential; they can be better leveraged to alleviate this issue.&#x0D; &#x0D; &#x0D; In the identified literature, there was a lack of explicit reporting around equity and ethical considerations for factors contributing to, and interventions to alleviate, ED overcrowding. Future work should strive to deliberately and explicitly include ethical considerations inherent in research, planning, and policy-making; considerations of equity-deserving groups; and dedicate the time needed to consider the various facets of this issue.&#x0D; This CADTH report and our series of reports on ED overcrowding are a starting point to bridge the literature, stakeholder discussion, and expert opinion to help decision-makers understand the various parts of the issue and consult the relevant updated evidence to inform their work.&#x0D;

Safety and Feasibility of an Emergency Department-to-Outpatient Pathway for Patients With TIA and Nondisabling Stroke.

Evaluation of transient ischemic attack/nondisabling ischemic strokes (TIA/NDS) in the emergency department (ED) contributes to capacity issues and increasing health care expenditures, especially high-cost duplicative imaging. As an institutional quality improvement project, we developed a novel pathway to evaluate patients with TIA/NDS in the ED using a core set of laboratory tests and CT-based neuroimaging. Patients identified as 'low risk' through a safety checklist were discharged and scheduled for prompt outpatient tests and stroke clinic follow-up. In this prespecified analysis designed to assess feasibility and safety, we abstracted data from patients consecutively enrolled in the first 6 months. We compared data from 106 patients with TIA/NDS enrolled in the new pathway from April through September 2020 (age 67.9 years, 45% female), against 55 unmatched historical controls with TIA encountered from April 2016 through March 2017 (age 68.3 years, 47% female). Both groups had similar median NIHSS scores (pathway and control 0) and ABCD2 scores (pathway and control 3). Pathway-enrolled patients had a 44% decrease in mean ED length of stay (pathway 13.7 hours, control 24.4 hours, p < 0.001) and decreased utilization of ED MRI-based imaging (pathway 63%, control 91%, p < 0.001) and duplicative ED CT plus MRI-based brain and/or vascular imaging (pathway 35%, control 53%, p = 0.04). Among pathway-enrolled patients, 89% were evaluated in our stroke clinic within a median of 5 business days; only 5.5% were lost to follow-up. Both groups had similar 90-day rates of ED revisits (pathway 21%, control 18%, p = 0.84) and recurrent TIA/ischemic stroke (pathway 1%, control 2%, p = 1.0). Recurrent ischemic events among pathway-enrolled patients were attributed to errors in following the safety checklist before discharge. Our TIA/NDS pathway, implemented during the initial outbreak of COVID-19, seems feasible and safe, with significant positive impact on ED throughput and ED-based high-cost duplicative imaging. The safety checklist and option of virtual telehealth follow-up are novel features. Broader adoption of such pathways has important implications for value-based health care.

Difficult Intravenous Access Requiring Ultrasound in the Emergency Department: Associations With Delays in Care and Areas for Quality Improvement.

Background Patients with difficult intravenous access (DIVA) requiring ultrasound-guided intravenous (USGIV) access have been associated with delays in treatment, imaging, and disposition in academic emergency department (ED) patient populations. Our objective in this study was to characterize differences in time to intravenous access, imaging, and disposition between patients with DIVA versus those without DIVA requiring USGIV access in a community ED while also assessing for DIVA-associated comorbidities. Methods A cross-sectional, observational analysis was performed on admitted ED patients evaluated from September 2to September 31, 2022, at a community ED. Patients with DIVA were defined as patients with two failed attempts at traditional intravenous placement. These patients require USGIV placement per institutional protocol. Patients younger than 18 years of age, trauma admissions, repeated visits from the same patient, patients with missing data, and direct hospital admissions were excluded. Continuous variables were recorded with medians and included ED throughput measures of time to vascular access, contrast CT imaging, and disposition. Differences in median times between DIVA patients versus non-DIVA patients were assessed with the Mann-Whitney U-test. Categorical data involving comorbidities were reported as percentages, and differences in proportions between DIVA versus non-DIVA patients were assessed via chi-square tests. Multivariate logistic regression analysis evaluated for correlations between DIVA and times to access, contrast CT imaging, disposition, and significant covariates while adjusting for demographic information. Results A total of 1250 patients were included in this investigation (5.8% associated with DIVA requiring USGIV access). The median age of all subjects was 69 (interquartile range = 58, 79) with no significant difference between the DIVA and non-DIVA groups. Patients with DIVA were more likely to be female in comparison to patients without DIVA (65.3% and 51.2%, respectively, p < 0.05). Patients with a history of end-stage renal disease (ESRD) (p < 0.001), intravenous drug use (IVDU) (p < 0.001), and venous thromboembolism (p < 0.05) had statistically significant associations with DIVA. On regression analysis, patients with DIVA were more likely to have a history of ESRD with an odds ratio (OR) of 3.56 (95% confidence interval (CI): 1.62-7.81) and a history of IVDU with an OR of 14.29 (95% CI: 5.17-39.54). Patients with DIVA were associated with statistically significant greater median times to vascular access, contrast CT imaging, and disposition (p < 0.001 for time to access and disposition and p < 0.01 for time to contrast CT imaging). Conclusion In this study, DIVA cases requiring USGIV access were positively associated with significantly longer times to access, contrast CT imaging, and disposition compared to patients without DIVA at our community ED. Comorbidities such as IVDU and ESRD had statistically significant associations with DIVA requiring USGIV access.

Mini-dose Bier's block vssystemic analgesia in distal radius fractures: a promising reduction in emergency department throughput time.

Aim: This study compared the effect of the conventional technique of procedural sedation and the mini-dose intravenous regional anesthesia (IVRA). Patients & methods: 45 patients received IVRA, and 47 received iv. ketamine. The pain score, emergency department (ED) length of stay and patients' satisfaction were compared. Results: The study revealed that not only the levels of hemodynamic parameters but also their stability, and the patient's satisfaction in the IVRA group were significantly better. The patients' pain score and ED length of stay were also significantly decreased in those who received IVRA. Conclusion: Mini-dose IVRA technique contributes to better hemodynamic stability, without prominent adverse events, and leads to significant pain control and improved ED throughput time. Clinical Trial Registration: NCT03349216 (ClinicalTrials.gov).

The contribution of physician associates or assistants to the emergency department: A systematic scoping review.

New health care professionals, such as the physician associate or assistant (PA), have expanded the ability of health systems to meet the needs of the population in both primary and secondary health care settings. Although PAs are widely deployed in the emergency department (ED), their role in the ED has not previously been formally described. This systematic scoping review synthesizes and critically analyzes existing literature on the impact and perception of the role of PAs working in the ED. We performed a systematic scoping review. We searched Medline, PubMed, Scopus, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE) and EMCare for English language peer-reviewed studies describing PA roles in the ED. Both qualitative and quantitative studies were included. We assessed the quality of the articles using QualSyst and the mixed methods appraisal tool. Themes regarding PA roles in the ED were identified. We included a total of 31 studies. Themes identified in the review included perceptions of the PA, wait times, acuity of patients seen, length of stay, those leaving without being seen (LWBS), clinical outcomes, pre-admission rates, well-being and scope of practice. Both the doctors' and patients' perception of PAs in the ED were generally high. The hindrance of them not being able to prescribe was evident. Studies showed a reduction in waiting times, length of stay, readmission rates, and those leaving without being seen when PAs work in the ED seeing moderate- to low-acuity patients. Evidence shows that PAs have a positive impact and the perceptions of the PAs are high in international EDs. There is significant evidence of PAs being key members of the health care team. Their work is particularly helpful for low- to moderate-acuity patients. With the increase in health care demand and a suffering UK National Health Service (NHS), the evidence synthesized in this review supports the potential positive impact PAs can have on the NHS and more specifically, the improvements of ED throughput metrics. This review identified the roles and positive influence of PAs in the ED. These findings highlight current and future challenges for PAs in the ED.

Mapping Nurses’ Advanced Roles in Emergency Departments Globally

Introduction:It is widely recognized that there is an increasing demand for healthcare in emergency departments (ED) around the world as well as a global shortage of healthcare workers (HCWs). This has led to ED overcrowding, which increases risks of avoidable complications and suboptimal care provision. Since ED overcrowding impacts patients, staff and quality of care, new strategies are needed for optimizing patient throughput and reducing waiting times. One such strategy is to reconsider the specific roles and professional duties of different cadres of HCWs. Empowering nurses to take on some of the tasks historically performed by physicians is a promising solution for improving ED healthcare provision. However, nurses’ professional responsibilities and competencies differ significantly from country to country. There are few studies about best practices and how to effectively implement such task-shifting strategies. The aim of this study is to map the evidence published in the scholarly literature on nurses’ advanced roles in ED as a strategy for reducing overcrowding, facilitating ED throughput, and, ultimately, improving quality of care.Method:A mapping review was performed by searching the following databases: PubMed, Embase, Scopus and Web of Science.Results:A total of 168 studies were analyzed and the data were grouped according to the countries where advanced tasks were implemented. The type of tasks that were carried out were: autonomous management of patients with minor injuries, triage-based ordering of exams and administration of therapy and management of patient flow.Conclusion:In some high-income countries having nurses take on advanced roles is well-established, and it contributes to reducing overcrowding in ED. Further evidence is needed to assess the barriers and facilitating factors to implementing this strategy in other contexts.

Reducing “Left without being seen” in a community emergency department: A rapid-cycle change project

Background and objective: The COVID-19 pandemic in 2020 increased the volume of patients seeking care in the Emergency Department (ED) for a respiratory crisis. Our community hospital experienced a filling of inpatient beds, leading to an overflow of admitted patients in the ED, where adequate staff (nurses, physicians, radiology, and laboratory staff), equipment, and rooms or places for patients were lacking. Times to obtain procedures that included cardiology, laboratory, and radiology performed and resulted significantly increased. Left without being seen (LWBS) is a challenge faced by EDs across the United States (US) and has become more prevalent since the COVID-19 pandemic. Best practice suggests an LWBS rate of less than 2%, but our hospital experienced an increasing rate of hitting over 5\% in January 2021. To reduce this rate, we implemented multiple rapid-cycle Plan-Do-Check-Act (PDCA) change interventions in triage and throughout the ED.Implementation/Methods: We implemented several rapid-cycle change interventions with a high-level action plan. These actions included hiring medical/surgical nurses to care for admitted patients awaiting beds, adding additional medical providers, implementing greeters, creating specialty chairs inside a major hospital thoroughfare, opening a 12-bed Admit Care Unit (ACU) adjacent to the ED, and more.Results: The rate of LWBS decreased from a high of 5.3% in January 2021 to 1.09% in January 2022.Conclusion/Implications to Practice: Patients in the ED recorded as LWBS are at higher risk for safety and quality transgressions. We continue to work toward excellent patient care by continuing to implement rapid-cycle changes in response to barriers as they arise. More research is needed to expand and rethink the process of ED throughput during pandemics and emergent national crises.

Association between Covid-19 surge and emergency department patient flow and experience

BackgroundPreparations for Covid-19 in the Netherlands included hospital reconfigurations to increase capacity for the expected surge at the emergency department (ED). We describe patients’ ED length of stay (LOS), crowding and experiences of patients with respiratory complaints during the first Covid-19 peak. MethodsRetrospective analysis of demand, ED LOS, crowding, and a patient experience survey during a 12-week period in 2020 and similar periods in 2018 and 2019. Crowding levels were calculated using the National ED OverCrowding Scale. ResultsThe number of patients with respiratory complaints increased significantly, while total ED numbers were unchanged. Although presentation during the Covid-19 peak and needing hospital admission were associated with a longer ED LOS in patients with respiratory complaints, significantly less crowding occurred compared with the 2018 and 2019 periods. Increased ED LOS was associated with lower patient experience scores. ConclusionAdvanced warning and its associated preparation within the hospital and the community prevented significant delays in ED throughput during the first Covid-19 peak.

14 The Impact of a Mixed Fast-Track and Mid-Acuity Track Area With a Vertical Component on Emergency Department Throughput

Fluctuations in staffing and patient volumes have stressed emergency department (ED) resources resulting in increased length of stay (LOS), increased door to doctor times for higher acuity patients, and increased left without being seen (LWBS) rates. Also, with the growing emergence of community urgent care centers, the need to staff a dedicated fast-track area in the ED has decreased. This study aimed to assess the impact of implementing a novel combined mid acuity track/fast track area with a vertical component that did not require additional department resources has on ED operations.

200 A Quantitative Assessment of Emergency Department Boarding and its Association With Decreases in Operational Efficiency: A Multicenter Nationwide Study

Boarding of emergency department (ED) patients is associated with worse patient care and increased mortality. Our local, multicenter study demonstrated an association between increased boarding and reductions in ED intake and throughput.

164 The Impact of Hallway Placement on Emergency Department Operations for Discharged Patients with Abdominal Pain

Emergency department (ED) crowding is a constant and relentless operational challenge facing hospitals across the country. In response to limited capacity many EDs increasingly care for patients in hallways to provide timely access to ED evaluation and facilitate ED flow. We sought to examine the impact of patient placement in the hallway on common ED throughput and quality measures for discharged abdominal pain patients.

49 Comparing the Safety and Efficacy of a Rapid High-Sensitivity Cardiac Troponin I Protocol Between Hospital-Based and Free-Standing Emergency Departments

Significant variability exists in patient population and diagnostic capabilities of large academic tertiary, community-based hospital, and free-standing emergency departments (ED). Current high sensitivity cardiac troponin I (hs-cTnI) research has been conducted almost exclusively in hospital-based ED (HBED) settings and the translation of these protocols into the free-standing EDs (FSED) has yet to be explored. This study compared the safety, efficacy, and ED throughput of applying a 0/1-hour, rapid-rule out protocol using hs-cTnI for exclusion of acute myocardial infarction (AMI) in HBEDs and FSEDs.

Comparison of emergency department throughput and process times between male and female patients: A retrospective cohort investigation by the Reducing Disparities Increasing Equity in Emergency Medicine Study Group.

IntroductionHealth equity for all patients is an important characteristic of an effective healthcare system. Bias has the potential to create inequities. In this study, we examine emergency department (ED) throughput and care measures for sex‐based differences, including metrics such as door‐to‐room (DTR) and door‐to‐healthcare practitioner (DTP) times to look for potential signs of systemic bias.MethodsWe conducted an observational cohort study of all adult patients presenting to the ED between July 2015 and June 2017. We collected ED operational, throughput, clinical, and demographic data. Differences in the findings for male and female patients were assessed using Poisson regression and generalized estimating equations (GEEs). A priori, a clinically significant time difference was defined as 10 min.ResultsA total of 106,011 adult visits to the ED were investigated. Female patients had 8‐min longer median length‐of‐stay (LOS) than males (P < 0.01). Females had longer DTR (2‐min median difference, P < 0.01), and longer DTP (5‐min median difference, P < 0.01). Females had longer median door‐to‐over‐the‐counter analgesia time (84 vs. 80, P = 0.58), door‐to‐advanced analgesia (95 vs. 84, P < 0.01), door‐to‐PO (by mouth) ondansetron (70 vs. 62, P = 0.02), and door‐to‐intramuscular/intravenous antiemetic (76 vs. 69, P = 0.02) times compared with males.ConclusionNumerous statistically significant differences were identified in throughput and care measures—mostly these differences favored male patients. Few of these comparisons met our criteria for clinical significance.

Investigating racial disparities within an emergency department rapid-triage system

ObjectivesRacial disparities in emergency medical care are abundant, and processes aimed to increase throughput, such as a rapid triage fast-track (FT) systems, may exacerbate these inequities. A FT strategy may be more susceptible to implicit bias as subjective information is obtained quickly. We aim to determine whether a FT model was associated with greater disparities between Black and White emergency department (ED) patients. MethodsTriage-related outcomes were compared across race using a cohort selected from encounters in an ED that uses a FT model. White and Black patient encounters were exact-matched on potential confounders including sex; presence of abnormal vital signs; ED arrival time; insurance type; age category; and chief complaint. The primary triage-related outcome was use of the FT area (versus the main ED), and the secondary outcomes were wait time and assigned encounter acuity. ResultsEncounters for 5151 Black patients were exact-matched with 7179 encounters for White patients. Weights were applied to address differential numbers of encounters from each group. Within this matched cohort, Black patients were more likely to be triaged to FT than White patients (odds ratio = 1.28, 95% CI: 1.12; 1.46) and less likely to be given a high acuity score (odds ratio = 0.73, 95% CI: 0.66, 0.81). Among the high-acuity patients, Black patients were 40% more likely to be triaged to the FT area. ConclusionsThese results suggest that, after controlling for potential confounders, racial disparities may have been exacerbated in a FT ED triage process. In a FT model utilizing physicians and midlevel providers, this may create tiered levels of care between Black and White patients – an unacceptable side-effect of an effort to increase ED throughput.

Do racial disparities exist at various time points during an emergency department visit for chest pain

IntroductionIt is well documented that disparities in patient care based on race and ethnicity are prevalent in the emergency medical care setting. In most cases these evaluations are patient focused and outcome based. The timeliness of patient treatment in the emergency department (ED) is correlated with patient outcomes. In this study, we sought to evaluate whether the timeliness of care for patients with chest pain across stages of care was impacted by patient race. MethodsThis was a retrospective evaluation of ED throughput times including adults who presented to one of seventeen EDs in a large healthcare system from January 1, 2019 to December 31, 2019 and met criteria for inclusion. The effect of race on different intervals of care were assessed. Generalized Linear Models were used to estimate the effect of race on different intervals of care while controlling for Charlson Comorbidity index, age, gender, insurance, ED facility type and emergency severity index acuity level. ResultsA total of 28,705 patients were included, with a mean age of 54 ± 18 years. The majority of patients were White (63%), female (56%) and had Medicare or Medicaid (56%). Black patients experienced significantly increased wait times for resident physician examination, advanced practice provider examination, attending physician examination, and ED disposition. There was no difference in time to triage between Black patients and White patients. ConclusionBlack patients have longer wait times for resident physician evaluation, advanced practice provider evaluation, attending physician evaluation, and ED disposition when presenting to the ED with chest pain.
