Emergency Department Observation Unit: Can It Be Funded Through Reduced Inpatient Admission?

Study objective: We sought to test the assumption that an emergency department observation unit can be funded through the reallocation of resources made available through the unit’s impact in reducing inpatient admissions and facilitating bed closures. Methods: We conducted our study in a tertiary care center ED with 46,000 visits annually. For a 3-month period, all patients admitted to the hospital through the ED were screened by an emergency physician for suitability for admission to an observation unit. Any patient in the hospital for 3 days or less who did not undergo surgery or other inpatient procedure, and who was admitted through the ED, was considered a candidate for the observation unit. Results: Of 1,840 admissions, 147 patients met the admission criteria. Only 48 (32.2%) could have been treated in an observation unit, and these patients were not admitted to any single unit in high frequency. The potential savings from inpatient bed closures would only have amounted to 1.68 full-time equivalents—not enough to staff a 4-bed observation unit, which would require 5 full-time equivalents. Conclusion: Because of the diffuse and inconsistent effect such a unit had on inpatient bed use, funding for an ED observation unit at our institution could not be justified on the basis of the closure of inpatient beds and transfer of resources.

The use and effectiveness of an emergency department observation unit for elderly patients

STUDY OBJECTIVE: Emergency department observation units are cost-effective alternatives to hospital admission for selected patients. However, the use and effectiveness of these units in the elderly population is unclear. We sought to describe the use of an ED observation unit by elderly patients (>or=65 years), to determine whether the ED observation unit is effective for them in terms of ED observation unit length of stay and hospital admission rates, and to compare efficacy and return visit rates between younger and older patients. METHODS: This is a retrospective observational cohort study of consecutive adult patients sent to an ED observation unit from 1996 to 2000 at a high-volume tertiary care suburban teaching hospital. ED observation unit length of stay of less than 18 hours and admittance rates of less than 30% were used as indicators of efficacy. Diagnosis, length of stay, hospital admission rates, and 30-day return visit rates were compared between younger and older patients. RESULTS: Twenty-two thousand five hundred and thirty adult patients were observed, with 37.2% older than 65 years of age. The most common diagnoses in elderly patients were chest pain (24.0%), dehydration (11.7%), syncope (6.5%), back pain (4.6%), and chronic obstructive pulmonary disease (3.8%). Length of stay in the ED observation unit was longer for the elderly than younger patients but still averaged less than 18 hours (15.8 hours [95% confidence interval (CI) 15.7 to 16.0] versus 14.4 hours [95% CI 14.3 to 14.5], respectively). Elderly patients were more likely to be admitted from the ED observation unit than younger patients (26.1% versus 18.5%); however, their overall admission rate remained less than 30%. Compared with younger patients, the odds ratios for inpatient admission of elderly patients was highest for back pain (2.10; 95% CI 1.62 to 2.73), pyelonephritis (1.78; 95% CI 1.16 to 2.71), and chest pain (1.65; 95% CI 1.44 to 1.89). Thirty-day related return visit rates between age groups were similar (9.4% versus 7.6%). CONCLUSION: Elderly ED observation unit patients had ED observation unit lengths of stay and hospital admission rates that were effective for an ED observation unit setting and ED return visits rates that were comparable with those of younger patients.     

Direct medical costs of pediatric asthma exacerbations requiring hospital attendance in a middle-income country

Introduction and objectivesWith the aim of making informed decisions on resource allocation, there is a critical need for studies that provide accurate information on hospital costs for treating pediatric asthma exacerbations, mainly in middle-income countries (MICs). The aim of the present study was to evaluate the direct medical costs associated with pediatric asthma exacerbations requiring hospital attendance in Bogota, Colombia.Patients and methodsWe reviewed the available electronic medical records (EMRs) for all pediatric patients who were admitted to the Fundacion Hospital de La Misericordia with a discharge principal diagnosis pediatric asthma exacerbation over a 24-month period from January 2016 to December 2017. Direct medical costs of pediatric asthma exacerbations were retrospectively collected by dividing the patients into four groups: those admitted to the emergency department (ED) only; those admitted to the pediatric ward (PW); those admitted to the pediatric intermediate care unit (PIMC); and those admitted to the pediatric intensive care unit (PICU).ResultsA total of 252 patients with a median (IQR) age of 5.0 (3.0–7.0) years were analyzed, of whom 142 (56.3%) were males. Overall, the median (IQR) cost of patients treated in the ED, PW, PIMC, and PICU was US$38.8 (21.1–64.1) vs. US$260.5 (113.7–567.4) vs. 1212.4 (717.6–1609.6) vs. 2501.8 (1771.6–3405.0), respectively: this difference was statistically significant (p < 0.001).ConclusionsThe present study helps to further our understanding of the economic burden of pediatric asthma exacerbations requiring hospital attendance among pediatric patients in a MIC.     

Nebulizer and Spacer Device Maintenance in Children with Asthma

Objective. To evaluate inhalation device cleaning practices of children with asthma and its effect on their asthma morbidity. Methods. A survey of patients aged 4 to 18 years admitted to an urban pediatric emergency department (ED) with an acute asthma exacerbation. Questions included demographics, asthma history, preference of delivery devices, and frequency of device cleaning. Patients were followed until their disposition from the ED, or until the end of their hospitalization, if admitted. Results. 220 subjects completed the survey. Mean age was 9.2 (± 3.9) years-old. One hundred and four (47.3%) patients used both nebulizers and spacer devices, while 18 (8.1%) used spacers only and 98 (44.5%) used nebulizers alone. Seventy-seven (38.1%; 95%CI: 31.7%–45.0%) patients cleaned their nebulizers and 57 (46.7%; 95%CI: 38.1%–55.4%) cleaned their spacer devices after each use as recommended by the Centers for Disease Control. There were no detectable differences in visit admission rate, total number of previous admissions, number of asthma exacerbations per year, and number of ED visits in one year between users who cleaned their devices after every, or every other use, compared to those who cleaned their devices less frequently. Conclusion. Although the majority of patients did not follow accepted guidelines for inhalation device cleaning, further studies are necessary to correlate cleaning practices to patients' clinical outcome.     

The Ontario Asthma Regional Variation Study: emergency department visit rates and the relation to hospitalization rates

BACKGROUND: Hospitalization rates for asthma vary more than threefold across regions of Ontario. It is not known whether this variation is primarily due to regional differences in the rate of emergency department (ED) visits or hospital admissions. OBJECTIVE: To determine the variation in ED visit rates for asthma in Ontario, and the relation between ED visit rates and hospitalization rates.Design, setting, and patients: We studied patients with an ED disposition diagnosis of asthma in a stratified sample of 16 hospitals (pediatric facilities, 13; adult facilities, 14) over a 1-year period. Pediatric patients were defined as those patients who were 相似文献   

Emergency department visits after pancreatoduodenectomy: examining a novel quality metric

BackgroundPostoperative emergency department (ED) visits represent fragmented care, are costly, and often evolve into readmission. Readmission rates after pancreatoduodenectomy (PD) are defined, while ED visits following PD are not. We examined the pattern of 30-day post-discharge ED visits for PD patients.MethodsA quaternary institutional database analysis of adult patients who underwent PD between 2010–2017 was reviewed for ED utilization within 30 days from discharge.ResultsOf the 1,004 patients who underwent PD, 12% (N = 117) patients sought care in the ED within 30 days from postoperative discharge. The median time to ED presentation was 5 days post-discharge (IQR 3–9). Half of ED visits occurred during nights and weekends (N = 59, 50%). Of ED-utilizing patients, 64% (N = 76) were admitted to the hospital and 29% (N = 34) were discharged from the ED. ED visits were associated with a Clavien-Dindo Classification of 0 in 10.2% (N = 13) of patients, I-II in 62.4% (N = 73), and III-V in 26.5% (N = 31).DiscussionPost-discharge ED utilization is a novel quality metric and represents a potential target population for reducing hospital readmissions. Over two-thirds (72%) of ED visits were associated with low acuity complications, and promoting institutional strategies addressing postoperative ED visits may improve patient care and efficient utilization of healthcare resources.     

Emergency department observation of heart failure: preliminary analysis of safety and cost

Emergency-department (ED)-based observation-unit treatment has been shown to reduce inpatient admissions, hospital bed-hours, and costs without adversely affecting outcomes for several conditions. A sequential group design study compared risk-matched, acute decompensated heart failure patients admitted directly to the inpatient setting with those admitted to an ED observation unit for up to 23 hours before ED disposition. Outcomes were 30-day readmissions or repeat ED visits for heart failure or 30-day mortality. Estimates of bed-hours and charges between the groups were compared. Sixty-four patients were enrolled with 36 inpatient admissions and 28 observation unit patients. No patients died within 30 days. Observation unit patients had no significant difference in outcomes, a decrease in time from ED triage to discharge, a saving in mean bed-hours, and less total charges. This pilot trial provides preliminary data that suggest admitted, low-risk heart failure patients may be safely and cost-effectively managed in an ED-based observation unit. These findings need to be further evaluated in a randomized clinical trial.     

Emergency Department Use by Nursing Home Residents

Study objective: To describe a community's experience with the use of emergency department services by nursing home residents. Methods: We performed a retrospective chart review of a population-based cohort of nursing home residents in an urban county in central Georgia with 10 nursing homes (1,300 beds) and 4 hospital-based EDs. All ED visits by nursing home residents during 1995 were analyzed. Demographic data, timing of the visit, chief complaint, tests and treatments, disposition, and financial charges were recorded. Further, we calculated the number of ED visits per 100 nursing home patient-years. Results: A total of 873 nursing home residents made 1,488 ED visits. Mean age was 76.0 years; 66.4% were female, and 55.2% were white. Of the transfers, 42.9% occurred during regular working hours. The most common chief complaints were respiratory symptoms (14.4%), altered mental status (10.1%), gastrointestinal symptoms (9.9%), and falls (8.2%); 101 patients (6.8%) were transferred for malfunction of a gastrostomy tube. The most common laboratory tests were complete blood cell count (69.5%), chest radiograph (52.0%), electrocardiogram (45.0%), urinalysis (42.7%), and determination of electrolytes (42.7%). A total of 42.4% of the ED visits led to admission to the hospital. From the 10 nursing homes, there were 110 ED visits per 100 patient-years. A 3.5-fold difference in ED use among these nursing homes could not be explained by age, gender, or other factors. The average charge per ED visit was $1,239. Conclusion: Elders living in nursing homes are frequently transferred to EDs for costly medical evaluations, and more than 40% of such visits lead to admission to the hospital.

Effect of inhaled corticosteroid use on weight (BMI) in pediatric patients with moderate-severe asthma

Objectives: Assess the relationship between inhaled corticosteroid use (ICS) and weight (BMI) in pediatric patients with moderate-severe asthma. Assess if the number of emergency department (ED) visits correlates with overall BMI trajectory. Assess the trend of prescribing biologic therapy in pediatric patients with moderate-severe asthma and determine its relationship with weight (BMI). Methods: A retrospective chart review was performed on 93 pediatric patients with moderate-severe asthma to determine the relationship between ICS use and weight (BMI), biologic therapy and BMI, and number of ED visits and BMI trajectory. A mixed effects model was employed with the correlation between repeated measures accounted for through the random effects. Results: There is a statistically significant increase of 0.369 kg/m² in BMI trajectory per year in subjects on high-dose steroids compared to an increase of 0.195 kg/m² in the low dose group (p < 0.05). The BMI of subjects initiated on biologic therapy (omalizumab or mepolizumab) had a statistically significant decrease in BMI trajectory of 0.818 kg/m² per year (p < 0.05). Subjects with ≥5 ED visits due to asthma exacerbations had a significantly higher BMI trajectory (p < 0.05). Conclusions: The potency of ICS use in pediatric patients with moderate-severe asthma affects BMI trajectory; the higher the dose, the greater the projected BMI increase per year. Initiation of biologic therapy decreased BMI trajectory over time. Lastly, those with frequent ED visits had a higher BMI trend. Future prospective studies are warranted that further evaluate the potential metabolic impacts of ICS and assess the effects of biologic therapy on BMI.     

Asthma treatment and outcomes for children in the emergency department and hospital

Objective: To describe and compare the treatment of acute asthma exacerbations in children given in the emergency department (ED) and admitted to acute care floor in the hospital or intensive care unit (ICU). Methods: A retrospective chart review of visits for acute exacerbation of asthma treated at Phoenix Children's Hospital between January 1, 2014 and December 31, 2016. Results: A total of 287 asthma exacerbation cases were identified including 106 (37%) ED visits, 134 (47%) hospital floor and 47 (16%) ICU admissions. A history of a previous ED visit (ED 88%, Floor 60% and ICU 68%; p < 0.0001) and prior pulmonology inpatient consultation (ED 30%, Floor 19% and ICU 15%; p = 0.05) varied significantly. Pulmonology inpatient consultations were performed more frequently in the ICU than on the hospital floor (54% versus 8%; p < 0.0001). Although overall 145 (51%) of the cases were already on inhaled corticosteroids (ICS) at the time of visit with no differences across locations, ICS initiation/step-up was greater in the ICU (72%) than on the hospital floor (54%) and ED (2%) (p < 0.0001). A recommendation given to the family for follow-up with pulmonology was more frequent for patients who had been admitted to the ICU (68%) as compared to those only admitted to the floor (31%) or ED (4%) (p < 0.0001). Readmission rates were similar for patients previously admitted to the hospital (Floor 42%; ICU 40%), but significantly higher for previous ED visits (77%) (p < 0.0001). Conclusions: Physicians in the ED have an opportunity to provide preventative care in the acute care setting and should be encouraged to initiate treatment with ICS. Consideration should be given to develop a program or clinical pathway focused on long-term asthma management and maintenance to reduce readmissions and long hospital stays.     

Effects of primary care coordination on public hospital patients

OBJECTIVE: To evaluate the effect of primary care coordination on utilization rates and satisfaction with care among public hospital patients. DESIGN: Prospective randomized gatekeeper intervention, with 1-year follow-up. SETTING: The Adult General Medical Clinic at San Francisco General Hospital, a university-affiliated public hospital. PATIENTS: We studied 2,293 established patients of 28 primary care physicians. INTERVENTION: Patients were randomized based on their primary care physician’s main clinic day. The 1,121 patients in the intervention group (Ambulatory Patient-Physician Relationship Organized to Achieve Coordinated Healthcare [APPROACH] group) required primary care physician approval to receive specialty and emergency department (ED) services; 1,172 patients in the control group did not. MEASUREMENTS AND MAIN RESULTS: Changes in outpatient, ED, and inpatient utilization were measured for APPROACH and control groups over the 1-year observation period, and the differences in the changes between groups were calculated to estimate the effect of the intervention. Acceptability of the gatekeeping model was determined via patient satisfaction surveys. RESULTS: Over the 1-year observation period, APPROACH patients decreased their specialty use by 0.57 visits per year more than control patients did (P=.04; 95% confidence interval [CI] −1.05 to −0.01). While APPROACH patients increased their primary care use by 0.27 visits per year more than control patients, this difference was not statistically significant (P=.14; 95% CI, −0.11 to 0.66). Changes in lowacuity ED care were similar between the two groups (0.06 visits per year more in APPROACH group than control group, P=.42; 95% CI, −0.09 to 0.22). APPROACH patients decreased yearly hospitalizations by 0.14 visits per year more than control patients (P=.02; 95% CI, −0.26 to −0.03). Changes in patient satisfaction with care, perceived access to specialists, and use of out-of-network services between the 2 groups were similar. CONCLUSIONS: A primary care model of health delivery in a public hospital that utilized a gatekeeping strategy decreased outpatient specialty and hospitalization rates and was acceptable to patients.     

Same-day discharge after elective percutaneous coronary intervention: A single center experience

Introduction and objectivesElective percutaneous coronary intervention (PCI) has become an increasingly safe procedure. However, same day discharge (SDD) has yet to become standard practice. Our aim is to characterize the patients who underwent elective PCI and compare outcomes between the overnight stay (ONS) patient group and the group that was discharged on the same day at 24 hours and at 30 days.MethodsOne-year registry of patients who underwent an elective PCI. The possibility of SDD was established by the operator. Appropriate candidates were discharged at least four hours after the end of the intervention. The primary endpoints were defined as: Major adverse cardiac and cerebrovascular events (MACCE) — death, myocardial infarction (MI) stroke or transient ischemic attack (TIA), non-planned re-intervention — and vascular complications. Secondary endpoints were any unplanned hospital visit, readmission and re-catheterization.ResultsWe performed 155 elective PCIs. One patient was admitted to the coronary care unit; 111 patients stayed overnight (ONS Group); 43 patients were discharged the same day (SDD Group). Three patients had early (<4 hours) post procedure complications: two TIAs and one vascular access site complication. There were no MACCE between four and 24 hours, nor at 30 days. At 24 hours, two patients from the SDD group had unplanned visits. Between one and 30 days, more patients from the SDD group had unplanned visits (9.3% vs. 0.9%. p=0.02). One patient from the ONS group had a recatherization. There were no readmissions or reinterventions.ConclusionSame day discharge of selected patients who undergo elective PCIs is feasible and safe.     

National Prevalence of Alcohol and Other Substance Use Disorders Among Emergency Department Visits and Hospitalizations: NHAMCS 2014–2018

BackgroundAcute healthcare utilization attributed to alcohol use disorders (AUD) and other substance use disorders (SUD) is rising.ObjectiveTo describe the prevalence and characteristics of emergency department (ED) visits and hospitalizations made by adults with AUD or SUD.Design, Setting, and ParticipantsObservational study with retrospective analysis of the National Hospital Ambulatory Medical Care Survey (2014 to 2018), a nationally representative survey of acute care visits with information on the presence of AUD or SUD abstracted from the medical chart.Main MeasuresOutcome measured as the presence of AUD or SUD.Key ResultsFrom 2014 to 2018, the annual average prevalence of AUD or SUD was 9.4% of ED visits (9.3 million visits) and 11.9% hospitalizations (1.4 million hospitalizations). Both estimates increased over time (30% and 57% relative increase for ED visits and hospitalizations, respectively, from 2014 to 2018). ED visits and hospitalizations from individuals with AUD or SUD, compared to individuals with neither AUD nor SUD, had higher percentages of Medicaid insurance (ED visits: AUD: 33.1%, SUD: 35.0%, neither: 24.4%; hospitalizations: AUD: 30.7%, SUD: 36.3%, neither: 14.8%); homelessness (ED visits: AUD: 6.2%, SUD 4.4%, neither 0.4%; hospitalizations: AUD: 5.9%, SUD 7.3%, neither: 0.4%); coexisting depression (ED visits: AUD: 26.3%, SUD 24.7%, neither 10.5%; hospitalizations: AUD: 33.5%, SUD 35.3%, neither: 13.9%); and injury/trauma (ED visits: AUD: 51.3%, SUD 36.3%, neither: 26.4%; hospitalizations: AUD: 31.8%, SUD: 23.8%, neither: 15.0%).ConclusionsIn this nationally representative study, 1 in 11 ED visits and 1 in 9 hospitalizations were made by adults with AUD or SUD, and both increased over time. These estimates are higher or similar than previous national estimates using claims data. This highlights the importance of identifying opportunities to address AUD and SUD in acute care settings in tandem with other medical concerns, particularly among visits presenting with injury, trauma, or coexisting depression.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11606-021-07069-w.KEY WORDS: substance-related disorders, substance use disorders, alcohol use disorder, hospitalization, emergency service, opioid use disorders, prevalence, national     

The Financial Impact of a Partnership Between an Academic Medical Center and a Free Clinic

PurposeThe objective of this study is to examine the association between an academic medical center and free clinic referral partnership and subsequent hospital utilization and costs for uninsured patients discharged from the academic medical center's emergency department (ED) or inpatient hospital.MethodsThis retrospective, cross-sectional study included 6014 uninsured patients age 18 and older who were discharged from the academic medical center's ED or inpatient hospital between July 2016 and June 2017 and were followed for 90 days in the organization's electronic medical record to identify the occurrence and cost of subsequent same-hospital ED visits and hospital admissions. The occurrence of any subsequent ED visits or hospital admissions and the cost of subsequent hospital care were compared by free clinic referral status after inverse probability of treatment weighting.ResultsOverall, 330 (5.5%) of uninsured patients were referred to the free clinic. Compared with patients referred to the free clinic, patients not referred had greater odds of any subsequent ED visits or hospital admissions within 90 days (odds ratio, 1.8; 95% confidence interval: 1.7-2.0). For patients with any subsequent ED visits or hospital admissions, the mean cost of care for those who were not referred to the free clinic was 2.3 times higher (95% confidence interval: 2.0-2.7) compared to referred patients.ConclusionAn academic medical center-free clinic partnership for follow-up care after discharge from the ED or hospital admission is a promising approach for improving access to care for uninsured patients.     

Continuity of antibiotic therapy in patients admitted from the emergency department

STUDY OBJECTIVE: We describe discontinuities in antibiotic therapy in patients with community-acquired pneumonia admitted from the emergency department (ED) to an inpatient unit. METHODS: We performed a retrospective cohort study of patients with community-acquired pneumonia admitted from the ED to the internal medicine service at an academic tertiary care hospital between July 1997 and June 1999. We characterized the frequency of antibiotic delays after arrival on the inpatient unit in relation to antibiotic dosing intervals. We performed paired analysis on the patients treated both with an antibiotic dosed every 6 hours and an antibiotic dosed every 24 hours. RESULTS: Three hundred seventy-five patients were identified. The mean age was 61 years. Sixty-two percent were female. Five hundred fifty-one antibiotic doses were started in the ED and continued on the inpatient unit, with 177 ordered every 6 hours, and 351 ordered every 24 hours. Seventy-five percent of the antibiotics dosed every 6 hours and 19% of the antibiotics dosed every 24 hours were delayed more than 30 minutes (P <.001). Analysis of the 146 patients receiving both an antibiotic dosed every 6 and 24 hours showed that the first inpatient dose of antibiotics administered every 6 hours were 10 times more likely to be delayed than antibiotics dosed every 24 hours (95% confidence interval 5.0 to 23). The median delay for antibiotics dosed every 6 hours was 258 minutes (range 45 to 3,360 minutes), and the median delay for antibiotics dosed every 24 hours was 192 minutes (range 32 to 2,124 minutes). CONCLUSION: Discontinuous therapy, represented through a delayed first inpatient antibiotic dose, is common in patients with community-acquired pneumonia admitted from the ED. Although the effect on outcome is unknown, theoretical concerns should lead emergency physicians to consider using longer-acting antibiotics to minimize delayed therapy.     

Asthma Exacerbations in North American Adults: Who Are the “Frequent Fliers” in the Emergency Department?

OBJECTIVE: To characterize adult asthma patients according to frequency of emergency department (ED) visits in the past year. DESIGN: Adults presenting with acute asthma to 83 US EDs underwent structured interviews in the ED and by telephone 2 weeks later. RESULTS: The 3,151 enrolled patients were classified into four groups: those reporting no ED visits in the past year (27%), one to two visits (27%), three to five visits (25%), and six or more visits (21%). The number of ED visits (NEDV) was associated with older age, nonwhite race, lower socioeconomic status, and several markers of chronic asthma severity (all p < 0.001). NEDV was strongly associated with Medicaid insurance (17% among those with no visits, 22% with one to two visits, 30% with three to five visits, 39% with six or more visits; p < 0.001). NEDV was unrelated to gender or having a primary care provider (PCP). In a multivariate model, independent predictors of high ED use (six or more visits a year) were nonwhite race, Medicaid, other public, and no insurance, and markers of chronic asthma severity. Patients with six or more ED visits accounted for 67% of all prior ED visits in the past year. CONCLUSIONS: High NEDV is associated with characteristics that may help with identification of "frequent fliers" in the ED. A better understanding of these characteristics may advance ongoing efforts to decrease asthma health-care disparities, including differential access to primary asthma care. National guidelines recommend specific ED treatments then referral to a PCP. Although longitudinal care is surely important, attempts to reduce frequent ED asthma visits may be better directed toward more specific preventive and educational needs.
