The impact on thirty day readmissions for patients hospitalized for acute exacerbations of chronic obstructive pulmonary disease admitted to an observation unit versus an inpatient medical unit: A retrospective observational study.

OBJECTIVES: We aimed to evaluate the utility of an Observation Unit (OU) in management of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and to identify the clinical characteristics of patients readmitted within 30-days for AECOPD following index admission to the OU or inpatient floor from the OU. METHODS: This is a retrospective observational study of patients admitted from January to December 2017 for AECOPD to an OU in an urban-based tertiary care hospital. Primary outcome was rate of 30-day readmission after admission for AECOPD for patients discharged from the OU versus inpatient service after failing OU management. Regression analyses were used to define risk factors. RESULTS: 163 OU encounters from 92 unique patients were included. There was a lower readmission rate (33%) for patients converted from OU to inpatient care versus patients readmitted after direct discharge from the OU (44%). Patients with 30-day readmissions were more likely to be undomiciled, with history of congestive heart failure (CHF), pulmonary embolism (PE), or had previous admissions for AECOPD. Patients with >6 annual OU visits for AECOPD had higher rates of substance abuse, psychiatric diagnosis, and prior PE; when these patients were excluded, the 30-day readmission rate decreased to 13.5%. CONCLUSION: Patients admitted for AECOPD with a history of PE, CHF, prior AECOPD admissions, and socioeconomic deprivation are at higher risk of readmission and should be prioritized for direct inpatient admission. Further prospective studies should be conducted to determine the clinical impact of this approach on readmission rates.

The feasibility of emergency department observation units in the management of mild to moderate hyponatremia.

OBJECTIVE: To describe the feasibility of managing hyponatremia patients under outpatient observation status in an academic medical center, and compare outcomes based on the use of an emergency department observation unit (EDOU). METHODS: This is a retrospective cohort study of emergency department hyponatremic patients managed in four hospitals within a large urban academic medical center over 27 months. All patients had an admit-to-observation order, ICD-10 codes for hyponatremia, and mild (130-135 mmol/L) to moderate (121-129 mmol/L) hyponatremia. Observation settings were divided into two groups: EDOU and Non-Observation Unit (NOU) inpatient beds. Severe hyponatremia (≤120 mmol/L) was excluded. Primary clinical outcomes were inpatient admit rate, length of stay (LOS), total direct cost, the rate of adverse events and 30-day recidivism. RESULTS: 188 patients were managed as an observation patient, with 64 managed in an EDOU setting (age 74.0 yr, 70.3% female) and 124 managed in a NOU setting (age 71.5 yr, 64.5% female). Patient subgroups were similar in terms of presenting complaints, comorbidities, and medication histories. Initial and final sodium levels were similar between settings: EDOU (125.1 to 132.6 mmol/L) vs NOU (123.5 to 132.0 mmol/L). However, outcomes differed by setting for observation to inpatient admit rate (EDOU 28.1% vs NOU 37.9%, adjusted effect 0.70), overall length of stay (EDOU 19.2 h vs NOU 31.9 h; adjusted effect -10.5 h and total direct cost ($1230 vs $1531; adjusted effect -$167). EDOU sodium correction rates were faster (EDOU 0.44 mmol/L/h vs 0.24 mmol/L/h; adjusted effect 0.15 mmol/L/h) and 30-day recidivism rate was similar (EDOU 13% vs NOU 15%). There were no index visit deaths or intensive care unit admissions. CONCLUSION: Management of selected hyponatremia patients under observation status is feasible, with the EDOU setting demonstrating lower admit rates, shorter length of stay, and lower total direct costs with similar clinical outcomes.

Impact of Geriatric Consult Evaluations on Hospital Admission Rates for Older Adults.

Introduction: We examined the impact of a geriatric consult program in the emergency department (ED) and an ED observation geriatric care unit (GCU) setting on hospital admission rates for older ED patients. Methods: We performed a retrospective case control study from June 1-August 31, 2019 (pre-program) to September 24, 2019-January 31, 2020 (post-program). Post-program geriatric consults were readily available in the ED and required in the GCU setting. Hospital admission rates (outcome) are reported for patients who received a geriatric consult evaluation (intervention). We analyzed probability of admission using a mixed-effects logistic regression model that included age, gender, recent ED visit, Charlson Comorbidity Index, referral to ED observation, and geriatric consult evaluation as predictor variables. Results: A total of 9,663 geriatric ED encounters occurred, 4,042 pre-program and 5,621 post-program. Overall, ED admission rates for geriatric patients were similar pre- and post-program (44.8% vs 43.9%, P = 0.39). Of 243 geriatric consults, 149 (61.3%) occurred in the GCU. Overall admission rates post-program for patients receiving geriatric intervention were significantly lower compared to pre-program (23.4% vs 44.9%, P < 0.001). Post-program GCU hospital admission rates were significantly lower than pre-program ED observation unit admission rates (14/149, 9.4%, vs 111/477, 23.3%, P < 0.001). In the logistic regression model, admissions post-program were lower when a geriatric consult evaluation occurred (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.41-0.83). Hospital admissions for older ED observation patients were also significantly decreased when a geriatric consult was obtained (GCU vs pre-program ED observation unit; OR 0.27, 95% CI 0.14-0.50). Conclusion: Geriatric consult evaluations were associated with significantly lower rates of hospital admission and persisted when controlled for age, gender, comorbidities, and ED observation unit placement. This model may allow healthcare systems to decrease potentially avoidable hospital admission rates in older ED patients.

Systematic Review of Psychiatric Observation Units and Their Impact on Emergency Department Boarding.

Objective: To investigate the effectiveness of acute short-stay hospital admissions in psychiatric observation units for improving the flow of patients with mental health presentations through the emergency department (ED).Data Sources: CINAHL, MEDLINE, OVID, PsycINFO, PubMed, Web of Science, and Google Scholar were systematically searched for English-language studies from 1990 onward. Descriptors used to describe psychiatric observation units were identified, and in databases with MESH term availability, the terms "mental disorder" and "emergency services, psychiatric" were also utilized to further enhance the search.Study Selection: A total of 6,571 studies were screened. The PICOS framework was used to determine the inclusion and exclusion criteria, and the process of study selection followed PRISMA guidelines. Articles were included if the unit studied had a length of stay (LOS) < 72 hours and if patients suffered from a mental health condition and were treated as hospital inpatients.Data Extraction: Reviewers performed data extraction and quality assessment of the included studies following the review protocol.Results: A total of 14 psychiatric observation unit studies were included in the review: 5 in North America and 9 in Australia. Most of these units were in large urban general hospitals. There appears to be some improvement in ED LOS for patients with mainly crisis mental health presentations. Seven of the 14 studies specifically discussed ED LOS, and 6 of these studies showed mild to moderate improvement in ED LOS, ranging from 17 minutes to > 11 hours.Conclusions: Psychiatric observation units were mainly located in North American and Australian settings. These units may reduce ED LOS based on limited, poor-quality evidence. Further research is required to determine whether psychiatric observation units have ongoing effects on ED LOS and alleviate access block.Prim Care Companion CNS Disord 2023;25(6):22r03468.

Hospital Development of a Hybrid Emergency Department-Inpatient Care Observation Unit.

INTRODUCTION: This project aimed to design and implement an emergency department-managed observation unit that improves inpatient bed and emergency department stretcher capacity, decreases observation patient length of stay, earns high patient satisfaction scores, and generates a positive fiscal impact on the organization. METHODS: This quality improvement project followed a 1-group, pre- and postprogram implementation design. RESULTS: In the first year of operations, 40% of the total observation patients treated in this hospital were managed in the new observation unit. Emergency department observation unit length of stay across all patient complaints was half of the average length of stay for observation patients located on hospital inpatient units. In most cases, the emergency department observation unit was in the top 25 percentile of hospital Press Ganey inpatient satisfaction categories. The hospital estimates a contribution margin of three-quarters of a million dollars in the first year. DISCUSSION: This effective and efficient hybrid observation unit possessed specific aspects of inpatient and emergency department patient care models. Placing providers and nurses at the workstation for faster communication expedited care. Prioritizing all observation patient testing, transportation, phlebotomy, and intravenous (IV) services shortened disposition times. Emergency nurses transitioning to the observation unit were challenged to acquire inpatient care knowledge. Observation unit management struggled to maintain staffing while under an inpatient productivity model managed by the inpatient house supervisor. Reducing patient disposition time required clear communication between observation unit and inpatient staffing managers, between physician consultants and advanced practice nursing providers, and among nurses, patients, and providers. Observation units are 1 solution to decrease observation patient length of stay and improve emergency department capacity.

Emergency Department Observation Unit Patients Want Evaluation and Treatment for Hypercholesterolemia: A Health Belief Model Study.

BACKGROUND: Hypercholesterolemia (HCL) is common among emergency department (ED) and ED observation unit (EDOU) patients with chest pain but is not typically addressed in these settings. The objective of this study was to assess patient attitudes towards EDOU-based HCL care using the Health Belief Model. METHODS: We conducted a cross-sectional survey study among 100 EDOU patients ≥18 years-old evaluated for chest pain in the EDOU of a tertiary care center from September 1, 2020, to November 01, 2021. Five-point Likert-scale surveys were used to assess each Health Belief Model domain: Cues to Action, Perceived Susceptibility, Perceived Barriers, Perceived Self-Efficacy, and Perceived Benefits. Responses were categorized as agree or do not agree. RESULTS: The participants were 49.0% (49/100) female, 39.0% (39/100) non-white, and had a mean age of 59.0 ± 12.4 years. Most (83.0% [83/100, 95% confidence interval (CI), 74.2%-89.8%]) agreed the EDOU is an appropriate place for HCL education and 52.0% (52/100, 95% CI, 41.8%-62.1%) were interested in talking with their EDOU care team about HCL. Regarding Perceived Susceptibility, 88.0% (88/100, 95% CI, 80.0%-93.6%) believed HCL to be bad for their health, while 41.0% (41/100, 95% CI, 31.3%-51.3%) believed medication costs could be a barrier. For Perceived Self-Efficacy, 76.0% (76/100, 95% CI, 66.4%-84.0%) were receptive to taking medications. Overall, 95.0% (95/100, 95% CI, 88.7%-98.4%) believed managing HCL would benefit their health. CONCLUSIONS: This Health Belief Model-based survey indicates high patient interest in EDOU-initiated HCL care. Patients reported high rates of Perceived Susceptibility, Self-Efficacy, and Benefits and a minority found HCL therapy costs a barrier.

Returns After Discharge From the Emergency Department Observation Unit: Who, What, When, and Why?

INTRODUCTION: The number of emergency department observation units (EDOU) and observation stays has continued to increase. Despite this, there is limited data on the characteristics of patients who return unexpectedly to the ED after EDOU discharge. METHODS: We identified the charts of all patients who were admitted to the EDOU of an academic medical center between January 2018-June 2020 and had a return to the ED within 14 days of discharge from the EDOU. Patients were excluded if they were admitted to the hospital from the EDOU, left against medical advice, or died in the EDOU. We manually extracted selected demographic factors, comorbidities, and healthcare utilization data from the charts. Physician reviewers identified return visits thought to be related to the index visit or potentially avoidable. RESULTS: During the study period, there were 176,471 ED visits, 4,179 admissions to the EDOU, and 333 return visits to the ED within 14 days from discharge from the EDOU, representing 9.4% of all patients discharged from the EDOU. We identified a higher rate of return for patients treated for asthma and lower rates of return for patients treated for chest pain or syncope than the overall return rate. Physician reviewers determined that 64.6% of unplanned returns were related to the index visit, and 4.5% were potentially avoidable. Of potentially avoidable visits, 53.3% occurred within 48 hours of discharge, supporting the use of this period as a potential quality metric. While there was no significant difference in the percentage of related return visits between males and females, there was a higher rate of potentially avoidable visits for male patients. CONCLUSION: This study adds to the limited body of literature on EDOU returns, finding an overall return rate of under 10%, with about two-thirds of returns determined to be related to the index visit and <5% considered to be potentially avoidable.

Rarely tested or treated but highly prevalent: Hypercholesterolemia in ED observation unit patients with chest pain.

BACKGROUND: Hypercholesterolemia (HCL) is common among Emergency Department (ED) patients with chest pain but is typically not addressed in this setting. This study aims to determine whether a missed opportunity for Emergency Department Observation Unit (EDOU) HCL testing and treatment exists. METHODS: We conducted a retrospective observational cohort study of patients ≥18 years old evaluated for chest pain in an EDOU from 3/1/2019-2/28/2020. The electronic health record was used to determine demographics and if HCL testing or treatment occurred. HCL was defined by self-report or clinician diagnosis. Proportions of patients receiving HCL testing or treatment at 1-year following their ED visit were calculated. HCL testing and treatment rates at 1-year were compared between white vs. non-white and male vs. female patients using multivariable logistic regression models including age, sex, and race. RESULTS: Among 649 EDOU patients with chest pain, 55.8% (362/649) had known HCL. Among patients without known HCL, 5.9% (17/287, 95% CI 3.5-9.3%) had a lipid panel during their index ED/EDOU visit and 26.5% (76/287, 95% CI 21.5-32.0%) had a lipid panel within 1-year of their initial ED/EDOU visit. Among patients with known or newly diagnosed HCL, 54.0% (229/424, 95% CI 49.1-58.8%) were on treatment within 1-year. After adjustment, testing rates were similar among white vs. non-white patients (aOR 0.71, 95% CI 0.37-1.38) and men vs. women (aOR 1.32, 95% CI 0.69-2.57). Treatment rates were similar among white vs. non-white (aOR 0.74, 95% CI 0.53-1.03) and male vs. female (aOR 1.08, 95% CI 0.77-1.51) patients. CONCLUSIONS: Few patients were evaluated for HCL in the ED/EDOU or outpatient setting after their ED/EDOU encounter and only 54% of patients with HCL were on treatment during the 1-year follow-up period after the index ED/EDOU visit. These findings suggest a missed opportunity to reduce cardiovascular disease risk exists by evaluating and treating HCL in the ED or EDOU.

Chest pain observation unit: A missed opportunity to initiate smoking cessation therapy.

BACKGROUND: Emergency Department Observation Unit (EDOU) patients with chest pain have a high prevalence of smoking, a key cardiovascular disease risk factor. While in the EDOU, there is an opportunity to initiate smoking cessation therapy (SCT), but this is not standard practice. This study aims to describe the missed opportunity for EDOU-initiated SCT by determining the proportion of smokers who receive SCT in the EDOU and within 1-year of EDOU discharge and to evaluate if SCT rates vary by race or sex. METHODS: We performed an observational cohort study of patients ≥18 years old being evaluated for chest pain in a tertiary care center EDOU from 3/1/2019-2/28/2020. Demographics, smoking history, and SCT were determined by electronic health record review. Emergency, family medicine, internal medicine, and cardiology records were reviewed to determine if SCT occurred within 1-year of their initial visit. SCT was defined as behavioral interventions or pharmacotherapy. Rates of SCT in the EDOU, 1-year follow-up period, and the EDOU through 1-year of follow-up were calculated. SCT rates from the EDOU through 1-year were compared between white vs. non-white and male vs. female patients using a multivariable logistic regression model including age, sex, and race. RESULTS: Among 649 EDOU patients, 24.0% (156/649) were smokers. These patients were 51.3% (80/156) female and 46.8% (73/156) white, with a mean age of 54.4 ± 10.5 years. From the EDOU encounter through 1-year of follow-up, only 33.3% (52/156) received SCT. In the EDOU, 16.0% (25/156) received SCT. During the 1-year follow-up period, 22.4% (35/156) had outpatient SCT. After adjusting for potential confounders, SCT rates from the EDOU through 1-year were similar among whites vs. non-whites (aOR 1.19, 95% CI 0.61-2.32) and males vs. females (aOR 0.79, 95% CI 0.40-1.56). CONCLUSIONS: SCT was rarely initiated in the EDOU among chest pain patients who smoke and most patients who did not receive SCT in the EDOU never received SCT at 1-year of follow-up. Rates of SCT were similarly low among race and sex subgroups. These data suggest an opportunity exists to improve health by initiating SCT in the EDOU.

Clinical Pharmacist Led Medication Reconciliation Program in an Emergency Department Observation Unit.

Objectives: Medication reconciliation is the process of comparing a patient's hospital medication orders to all of the medications that the patient has been taking prior to admission. The primary aim of this study was to evaluate the effectiveness of pharmacist-led medication reconciliation in reducing ED visit rates. The secondary aim of this study was to evaluate if a clinical pharmacist reduces medication errors in an ED observation unit (OBS). Methods: This was a retrospective, IRB approved, chart review conducted at New York University Langone Health-Tisch Hospital. The study defines the year before a clinical pharmacist was present on the unit (July 5, 2016 through July 4, 2017) as the control group and the first year a clinical pharmacist was present on the unit (July 5, 2017 through July 4, 2018) as the intervention group. The primary endpoint was 30-day ED re-visits. The secondary endpoints were 60-and 90-day ED re-visits, number, type and severity of medication history and reconciliation discrepancies. Results: The primary endpoint of 30-day ED visits occurred in 153 patients in the no pharmacist group and 88 patients in the OBS clinical pharmacist group (19.1% vs 9.9%, P < .00001). The secondary endpoint of 60- day ED visits occurred in 53 patients in the no pharmacist group and 39 patients in the OBS clinical pharmacist group (8.2% vs 4.9%, P = .01). The secondary endpoint of 90- day ED visits occurred in 31 patients in the no pharmacist group and 26 patients in the OBS clinical pharmacist group (5.2% vs 3.4%, P = .01). Conclusion: The benefits of having a clinical pharmacist perform medication reconciliation are highlighted by the reduction in ED visits, cost savings, and the prolific amount of errors corrected.

Implementing a COVID-19 Virtual Observation Unit in Emergency Medicine: Frontline Clinician and Staff Experiences.

The COVID-19 pandemic pushed hospitals to deliver care outside of their four walls. To successfully scale virtual care delivery, it is important to understand how its implementation affects frontline workers, including their teamwork and patient-provider interactions. We conducted in-depth interviews of 17 clinicians and staff involved with the COVID-19 Virtual Observation Unit (CVOU) in the emergency department (ED) of an academic hospital. The program leveraged remote patient monitoring and mobile integrated health care. In the CVOU (vs. the ED), participants observed increases in interactions among clinicians and staff, patient participation in care delivery, attention to nonmedical factors, and involvement of coordinators and paramedics in patient care. These changes were associated with unintended, positive consequences for staff, namely, feeling heard, experience of meaningfulness, and positive attitudes toward virtual care. This study advances research on reconfiguration of roles following implementation of new practices using digital tools, virtual work interactions, and at-home care delivery.

The Impact of Virtual Care in an Emergency Department Observation Unit.

STUDY OBJECTIVE(S): We report the impact of telemedicine virtual rounding in emergency department observation units (EDOU) on the effectiveness, safety, and cost relative to traditional observation care. METHODS: In this retrospective diff-in-diff study, we compared observation visit outcomes from 2 EDOUs before (pre) and after (post) full adoption of telemedicine rounding tele-observation (tele-obs) with usual care in control EDOU and care in a hospital bed in an integrated health system without tele-obs. Tele-obs physicians did not work at the control hospital. Outcomes were the length of stay, total direct costs, admission status, and adverse events (ICU and death). Difference-in-differences modeling evaluated outcomes with covariates including age, sex, payer type, and clinical classification software diagnostic category. Data from a system data warehouse and a cost accounting database were used. RESULTS: Of the 20,861 EDOU visits, 15,630 (74.9%) were seen in the preperiod and 6,657 (31.9%) in control EDOU. Of 23,055 non-EDOU inpatient visits assigned to observation status (nonobservation unit), 76% were seen in the preperiod. Adjusted length of stay was not significantly different for tele-obs and control EDOUs (26.4 hours versus 23.5 hours), which remained lower than in hospital settings (37.9 hours). The pre-post diff-in-diff was not significant (P=.78). Inpatient admission status was similar for tele-obs and control EDOUs (20.9% versus 22.4.%) and lower than in hospital settings (30.3%). Prepost odds ratios for inpatient admission and adverse outcomes did not change significantly for all study groups. Adjusted costs increased over time for all settings; however, the prepost median cost change was not significantly different between tele-obs EDOUs and control EDOUs ($162.5 versus $235) and was lower than the change for control hospital settings ($783). Median tele-obs EDOU cost over both periods ($1,541) remained significantly lower than hospital costs ($2,413). CONCLUSION: Using tele-obs to manage observation patients in an ED observation unit was not associated with significant differences in length of stay, admission status, measured adverse events, or total direct cost.

Atuação em urgência e emergência a partir da psicologia junguiana / The pratice in an emergency service based on jungian psychology / La práctica en la urgencia y emergencia desde la psicología junguiana

Este artigo é um relato de experiência cujo objetivo é refletir sobre a atuação de uma psicóloga no contexto da urgência e emergência no hospital a partir da psicologia jungiana. Utilizou-se como método o recurso da sistematização da experiência, que consiste em sua interpretação crítica, cujo foco é o ordenamento e a reconstrução das experiências para explicitar a lógica do processo vivido. Por meio da reflexão de situações clínicas foi possível proporcionar um lugar para a subjetividade diante do disruptivo e da objetividade institucional do hospital. Teoricamente, o texto descreve as experiências de atendimento hospitalar, espaço em que urge o inesperado e o desconhecido. Aposta-se no simbolismo como movimento da psique para lidar com aquilo que o sujeito ainda não pode nomear, significar, incluindo a vulnerabilidade, as perdas e a questão da morte e do luto, este entendido como a ruptura de um vínculo. Dessa forma, a psicologia analítica se volta para como a entrada no hospital e a fugacidade do contexto de urgência e emergência afetam a psique dos sujeitos atendidos e de que forma esse psiquismo reage às vivências disruptivas e inesperadas.(AU)

This work is an experience report whose objective is to reflect on the role of a psychologist in the context of urgency and emergency in the hospital from the perspective of Jungian psychology. The resource of systematization of the experience was used as method, which consists of a critical interpretation, whose focus is the ordering and reconstruction of experiences to explain the logic of the process experienced. With the reflection of clinical situations, it was possible to provide a place for subjectivity in the face of the disruptive and the institutional objectivity of the hospital. Theoretically, the text describes the experience of entry in a hospital, a place in which the unexpected and the unknown are faced. We believe on symbolism as a movement of the psyche to deal with what the patient cannot yet name or give a meaning, including vulnerability, losses, and the issue of death and grief, this last one understood as the rupture of a link. Thus, analytical psychology will focus on how the entry in a hospital and the fleetingness of the emergency context affect the psyche of the patients and how this psyche reacts to the disruptive and unexpected experiences.(AU)

Evaluating smoking cessation service at an emergency department clinical observation unit.

OBJECTIVES: To evaluate the effectiveness of a pilot smoking cessation service in an emergency department (ED) clinical observation unit. STUDY DESIGN: A descriptive case series review was undertaken of smoking cessation service patients in the short-stay unit of an acute hospital in Singapore from July 1, 2018, to December 31, 2019. METHODS: Upon admission, ED nurses screen all patients regarding their current smoking status and implement the 5 A's framework, which involves the steps of Ask-Advise-Assess-Assist-Arrange. Patients in the "contemplation" and "preparation" stages were offered the following components: (1) a bedside counseling session by a pharmacist and (2) a follow-up appointment at an outpatient smoking cessation clinic. Postdischarge follow-up telephone calls at 1, 6, and 12 months were carried out as part of the study data collection to obtain abstinence information. RESULTS: Forty-seven patients were included in the study; the majority were male (n = 41; 87.2%). The median numbers of cigarettes smoked per day at baseline, 1 month, 6 months, and 12 months were 14, 5, 3, and 5, respectively. The overall point-prevalence abstinence rates over the same follow-up time points were 26.5%, 38.7%, and 31.3%, respectively. The proportions of patients lost to follow-up at 1 month, 6 months, and 12 months were 27.7%, 34.0%, and 31.9%, respectively. CONCLUSIONS: Given the small sample and high number of uncontactable patients, more research is needed to assess whether the trend toward increasing point-prevalence abstinence rate over time and the trend toward decreasing median number of cigarettes smoked are observed in a larger sample.

Blood Pressure Assessment and Treatment in the Observation Unit.

PURPOSE OF REVIEW: To review the pathophysiology, diagnosis, and the management of hypertension. Given the paucity of literature regarding the role of the observation unit in the management of hypertension, we will provide our recommendations based on our experience working in an observation unit. RECENT FINDINGS: Many patients have limited access to primary care, and hypertension diagnosis often relies on office-based measurements. We will describe situations where that is not necessary to make the diagnosis. We will discuss the current non-pharmacologic treatment guidelines, the education of which should be provided to patients both in the emergency department and observation units. We will provide the current recommendations on what anti-hypertension medications can be initiated in the emergency department and observation units. Hypertension is a leading cause of morbidity and mortality in the USA. The utility of an observation unit in the diagnosis and management of patients with hypertension is beneficial particularly for those with risk factors for atherosclerotic disease. An observation unit stay provides the opportunity to diagnosis hypertension, initiate lifestyle education and pharmacologic treatment if indicated, and help to arrange appropriate follow-up for ongoing management and treatment in individuals with limited access to care.

Evaluation of a COVID-19 emergency department observation protocol.

OBJECTIVES: Caring for patients with COVID-19 has resulted in a considerable strain on hospital capacity. One strategy to mitigate crowding is the use of ED-based observation units to care for patients who may have otherwise required hospitalization. We sought to create a COVID-19 Observation Protocol for our ED Observation Unit (EDOU) for patients with mild to moderate COVID-19 to allow emergency physicians (EP) to gather more data for or against admission and intervene in a timely manner to prevent clinical deterioration. METHODS: This was a retrospective cohort study which included all patients who were positive for SARS-CoV-2 at the time of EDOU placement for the primary purpose of monitoring COVID-19 disease. Our institution updated the ED Observation protocol partway into the study period. Descriptive statistics were used to characterize demographics. We assessed for differences in demographics, clinical characteristics, and outcomes between admitted and discharged patients. Multivariate logistic regression models were used to assess whether meeting criteria for the ED observation protocols predicted disposition. RESULTS: During the time period studied, 120 patients positive for SARS-CoV-2 were placed in the EDOU for the primary purpose of monitoring COVID-19 disease. The admission rate for patients in the EDOU during the study period was 35%. When limited to patients who met criteria for version 1 or version 2 of the protocol, this dropped to 21% and 25% respectively. Adherence to the observation protocol was 62% and 60% during the time of version 1 and version 2 implementation, respectively. Using a multivariate logistic regression, meeting criteria for either version 1 (OR = 3.17, 95% CI 1.34-7.53, p < 0.01) or version 2 (OR = 3.18, 95% CI 1.39-7.30, p < 0.01) of the protocol resulted in a higher likelihood of discharge. There was no difference in EDOU LOS between admitted and discharged patients. CONCLUSION: An ED observation protocol can be successfully created and implemented for COVID-19 which allows the EP to determine which patients warrant hospitalization. Meeting protocol criteria results in an acceptable admission rate.

Untapped Potential for Emergency Department Observation Unit Use: A National Hospital Ambulatory Medical Care Survey (NHAMCS) Study.

INTRODUCTION: Millions of people present to the emergency department (ED) with chest pain annually. Accurate and timely risk stratification is important to identify potentially life-threatening conditions such as acute coronary syndrome (ACS). An ED-based observation unit can be used to rapidly evaluate patients and reduce ED crowding, but the practice is not universal. We estimated the number of current hospital admissions in the United States (US) eligible for ED-based observation services for patients with symptoms of ACS. METHODS: In this cross-sectional analysis we used data from the 2011-2015 National Hospital Ambulatory Medical Care Survey (NHAMCS). Visits were included if patients presented with symptoms of ACS (eg, chest pain, dyspnea), had an electrocardiogram (ECG) and cardiac markers, and were admitted to the hospital. We excluded patients with any of the following: discharge diagnosis of myocardial infarction; cardiac arrest; congestive heart failure, or unstable angina; admission to an intensive care unit; hospital length of stay > 2 days; alteplase administration, central venous catheter insertion, cardiopulmonary resuscitation or endotracheal intubation; or admission after an initial ED observation stay. We extracted data on sociodemographics, hospital characteristics, triage level, disposition from the ED, and year of ED extracted from the NHAMCS. Descriptive statistics were performed using sampling weights to produce national estimates of ED visits. We provide medians with interquartile ranges for continuous variables and percentages with 95% confidence intervals for categorical variables. RESULTS: During 2011-2015 there were an estimated 675,883,000 ED visits in the US. Of these, 14,353,000 patients with symptoms of ACS and an ED order for an ECG or cardiac markers were admitted to the hospital. We identified 1,883,000 visits that were amenable to ED observation services, where 987,000 (52.4%) were male patients, and 1,318,000 (70%) were White. Further-more, 739,000 (39.2%) and 234,000 (12.4%) were paid for by Medicare and Medicaid, respectively. The majority (45.1%) of observation-amenable hospitalizations were in the Southern US. CONCLUSION: Emergency department-based observation unit services for suspected ACS appear to be underused. Over half of potentially observation-amenable admissions were paid for by Medicare and Medicaid. Implementation of ED-based observation units would especially benefit hospitals and patients in the American South.

Verification of Usefulness of Pediatric Head Trauma Imaging Protocol Combining Computerized Tomography, Observation Unit, and Magnetic Resonance Imaging.

METHODS: This prospective observational study conducted in our hospital between October 2016 and September 2019 included 1946 patients aged 0 to 15 years with head trauma, of whom 1137 were analyzed. Computed tomography scan rate and imaging examination (CT or MRI) rate of our protocol were investigated. Sensitivity and negative predictive value (NPV) were calculated. We also compared our protocol and other clinical decision rules with respect to CT scan rate, sensitivity, and NPV in the same cohort and outcomes. RESULTS: The CT scan rate of our protocol was 7.9%, and the imaging examination rate, including MRI, was 12.2%. When the outcome was set to intracranial injury, the sensitivity and NPV of our protocol were each 100%. The CT scan rates in each cohort were 14.5% for PECARN (8.1% for our protocol), 34.7% for CATCH (23.2% for ours), and 13.6% for CHALICE (7.9% for ours). The sensitivity and NPV in each cohort were 100% and 100% for PECARN (92.3% and 100% for ours), 64.7% and 92.6% for CATCH (100% and 100% for ours), and 83.9% and 99.5% for CHALICE (100% and 100% for ours), respectively. CONCLUSIONS: The protocol we created by combining CT, observation unit, and MRI was considered to be useful for practice in pediatric head injury cases.

German emergency department measures in 2018: a status quo based on the Utstein reporting standard.

BACKGROUND: Compelling data on clinical emergency medicine is required for healthcare system management. The aim of this survey was to describe the nationwide status quo of emergency care in Germany at the healthcare system level using the Utstein reporting template as the guideline to measure the data collected. METHODS: This cross-sectional survey collected standardized data from German EDs in 2018. All 759 of the EDs listed in a previously collected ED Directory were contacted in November 2019 using the online-survey tool SoSci Survey. Exclusively descriptive statistical analyses were performed. Absolute as well as relative frequencies, medians, means, ranges, standard deviations (SD) and interquartile ranges (IQR) were reported depending on distribution. MAIN RESULTS: A total of 150 questionnaires of contacted EDs were evaluated (response rate: 19.8%). Hospitals had a median of 403 inpatient beds (n=147). The EDs recorded a median of 30,000 patient contacts (n=136). Eighty-three EDs (55%) had observation units with a median of six beds. The special patient groups were pediatric patients (< 5 years) and older patients (> 75 years) with a median of 1.7% and 25%, respectively. Outpatients accounted for 55%, while 45% were admitted (intensive care unit 5.0%, standard care unit 32.3%, observation unit 6.3%) and 1.2% transferred to another hospital. CONCLUSIONS: The use of the Utstein reporting template enabled the collection of ED descriptive parameters in Germany. The data can provide a baseline for upcoming reforms on German emergency medicine, and for international comparisons on admission rates, initial triage categories, and patient populations.

The mediating and moderating effects of shared decision making and medical autonomy on improving medical service satisfaction in emergency observation units.

OBJECTIVE: Distinct from other medical settings, the emergency setting is unique and requires flexible and adaptive decision making to provide quality medical services. This study was designed to investigate the mediating and moderating effects of shared decision making (SDM) and patient attitude toward medical autonomy (AMA) on improving medical service satisfaction (MSS) in emergency observation units. METHODS: In this cross-sectional study, we collected data via a verified structured questionnaire. A total of 165 participants met the inclusion criteria, and 100% of the questionnaires recovered were valid. RESULTS: The results show that SDM had a partial mediating effect (p < 0.01) and that it significantly improved MSS. AMA had a moderating effect on some domains (p < 0.01). Meeting patient needs and increasing their participation in decision making can effectively improve MSS. However, excessive patient participation might not be productive, which is an important finding of this study. CONCLUSION: In emergency observation units, SDM-based doctor-patient interactions and cooperation, effective patient-centered communication, and respect for patients' medical autonomy improve the doctor-patient relationship and patients' health literacy. Patients can thus participate in selecting the best treatment plan to achieve expected health outcomes, and ultimately improve MSS.
