Revisit rates and associated costs after an emergency department encounter: a multistate analysis

Using a clinical narrative-aware pre-trained language model for predicting emergency department patient disposition and unscheduled return visits

The increasing prevalence of overcrowding in Emergency Departments (EDs) threatens the effective delivery of urgent healthcare. Mitigation strategies include the deployment of monitoring systems capable of tracking and managing patient disposition to facilitate appropriate and timely care, which subsequently reduces patient revisits, optimizes resource allocation, and enhances patient outcomes. This study used ∼ 250,000 emergency department visit records from Taipei Medical University-Shuang Ho Hospital to develop a natural language processing model using BlueBERT, a biomedical domain-specific pre-trained language model, to predict patient disposition status and unplanned readmissions. Data preprocessing and the integration of both structured and unstructured data were central to our approach. Compared to other models, BlueBERT outperformed due to its pre-training on a diverse range of medical literature, enabling it to better comprehend the specialized terminology, relationships, and context present in ED data. We found that translating Chinese-English clinical narratives into English and textualizing numerical data into categorical representations significantly improved the prediction of patient disposition (AUROC = 0.9014) and 72-hour unscheduled return visits (AUROC = 0.6475). The study concludes that the BlueBERT-based model demonstrated superior prediction capabilities, surpassing the performance of prior patient disposition predictive models, thus offering promising applications in the realm of ED clinical practice.

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

OBJECTIVE

This study aimed to identify predictive biomarkers for unscheduled emergency department (ED) revisits within 24 hours of discharge in infants diagnosed with acute bronchiolitis (AB).

METHODS

A retrospective observational study was conducted on infants diagnosed with AB who visited 3 emergency medical centers between January 2020 and December 2022. The study excluded infants with comorbidities, congenital diseases, and prematurity and infants who revisited the ED after 24 hours of discharge. Demographic data, vital signs, and laboratory results were collected from the medical records. Univariable and multivariable logistic regression analyses were performed on factors with P of less than 0.1 in univariable analysis. Receiver operator curve analysis was used to assess the accuracy of lactate measurements in predicting ED revisits within 24 hours of discharge.

RESULTS

Out of 172 participants, 100 were in the revisit group and 72 in the discharge group. The revisit group was significantly younger and exhibited higher lactate levels, lower pH values, and higher pCO2 levels compared to the discharge group. Univariable logistic regression identified several factors associated with revisits. Multivariable analysis found that only lactate was a variable correlated with predicting ED revisits (odds ratio, 18.020; 95% confidence interval [CI], 5.764-56.334). The receiver operator curve analysis showed an area under the curve of 0.856, with an optimal lactate cutoff value of 2.15.

CONCLUSION

Lactate value in infants diagnosed with AB were identified as a potential indicator of predicting unscheduled ED revisits within 24 hours of discharge. The predictive potential of lactate levels holds promise for enhancing prognosis prediction, reducing health care costs, and alleviating ED overcrowding. However, given the study's limitations, a more comprehensive prospective investigation is recommended to validate these findings.

Predictors for emergency readmission in patients with ureteral calculi: a focus on pain management and stone location

BACKGROUND

The management of patients with ureteral calculi in the emergency department (ED) remains challenging due to high revisit rates.

PURPOSE

To identify predictors of revisits among patients with ureteral calculi in the ED.

DESIGN, SETTING, AND PARTICIPANTS

Data from patients who presented at a tertiary academic hospital in Seoul, Republic of Korea, between February 2018 and December 2019, were analyzed retrospectively.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Variables, including the respiratory rate (RR), estimated glomerular filtration rate (eGFR), duration of pain, number of analgesic doses, location of ureteral calculi, and ED length of stay (LOS) were examined using logistic regression. We also examined some additional variables included in the STONE and CHOKAI scoring systems to examine their association with revisit.

RESULTS

Significant predictors of revisits included the number of analgesic doses and the location of ureteral calculi. Patients who required multiple analgesic doses or those with proximal or mid-ureteral calculi were more likely to revisit the ED. Although the STONE and CHOKAI scores could predict uncomplicated ureteral calculi, we found that the CHOKAI score is a valuable tool for predicting the likelihood of patient revisits (p = 0.021).

CONCLUSIONS

Effective pain management and consideration of calculi location are important for predicting patient revisits. More research is required to validate findings, develop precise predictive models, and empower tailored care for high-risk patients. In patients with ureteral calculi in the ED, the number of analgesics given and stone location predict return visits. Proximal ureteral calculi on CT may require early urologic intervention to prevent pain-related revisits.

Characteristics of patients who return unplanned to the ED, and factors that contribute to their decision to return: Integrated results from an explanatory sequential mixed methods inquiry

AIM

To identify common characteristics of patients who return to the ED unplanned and factors that may contribute to their decision to return.

BACKGROUND

Return visits to the Emergency Department (ED) have been associated with adverse events and deficits in initial care provided. There is increasing evidence to suggest that many return visits may be preventable.

METHODS

The results of primary quantitative measures (QUAN) followed by qualitative measures (qual) were integrated to build on and explain the quantitative data found in the initial phase of the research.

RESULTS

Integration of results produced three new findings. 1) Most return visits occurred beyond 48 hrs because patients intentionally delayed going back to the ED despite their persisting symptoms; 2) Clinical urgency and deterioration were rarely evident in patients who made return visits in patients and 3) Ineffective communication between the clinician and the patient at discharge may have contributed to patients making the decision to return to the ED.

CONCLUSION

The decision to return unplanned to the ED is not an immediate response for most patients, and several potentially avoidable factors may influence their decision-making process. Future research should focus on strategies which contribute to the avoidance of unplanned return visits.

Patient-reported outcome measure use among older adults after emergency department care: A systematic review

BACKGROUND

Patient-reported outcome measures (PROMs) are gaining favor in clinical and research settings given their ability to capture a patient's symptom burden, functional status, and quality of life. Our objective in this systematic review was to summarize studies including PROMs assessed among older adults (age ≥ 65 years) after seeking emergency care.

METHODS

With the assistance of a medical librarian, we searched Ovid MEDLINE, PubMed, Embase, CINAHL, Web of Science-Core Collection, and Cochrane CENTRAL from inception through June 2023 for studies in which older adult ED patients had PROMs assessed in the post-emergency care time period. Independent reviewers performed title/abstract review, full-text screening, data extraction, study characteristic summarization, and risk-of-bias (RoB) assessments.

RESULTS

Our search strategy yielded 5153 studies of which 56 met study inclusion criteria. Within included studies, 304 unique PROM assessments were performed at varying time points after the ED visit, including 61 unique PROMs. The most commonly measured domain was physical function, assessed within the majority of studies (47/56; 84%), with measures including PROMs such as Katz activities of daily living (ADLs), instrumental ADLs, and the Barthel Index. PROMs were most frequently assessed at 1-3 months after an ED visit (113/304; 37%), greater than 6 months (91/304; 30%), and 4-6 months (88/304; 29%), with very few PROMs assessed within 1 month of the ED visit (12/304; 4%). Of the 16 interventional studies, two were determined to have a low RoB, four had moderate RoB, nine had high RoB, and one had insufficient information. Of the 40 observational studies, 10 were determined to be of good quality, 20 of moderate quality, and 10 of poor quality.

CONCLUSIONS

PROM assessments among older adults following an ED visit frequently measured physical function, with very few assessments occurring within the first 1 month after an ED visit.

Emergency Department-to-Community Transitions of Care: Best Practices for the Older Adult Population

This article describes emergency department (ED)-to-community care transitions for older adults and associated challenges, measurement, proven efficacious and effective interventions, and policy considerations. Older adults experiencing social isolation and impairments in functional status or cognition represent unique populations that are particularly at risk during ED-to-community transitions of care and may benefit from targeted intervention implementation. Future efforts should target optimizing screening techniques to identify those at risk, developing and validating patient-centered outcome measures, and using policy and reimbursement levers to include transitional care management services for older adults within the ED setting.

Factors influencing recurrent emergency department visits for mild acute respiratory tract infections caused by the influenza virus

Background

Seasonal viral outbreaks, exemplified by influenza A and B viruses, lead to spikes in emergency department (ED) visits, straining healthcare facilities. Addressing ED overcrowding has become paramount due to its implications for patient care and healthcare operations. Recurrent visits among influenza patients remain an underexplored aspect, necessitating investigation into factors influencing such revisits.

Methods

Conducted within a tertiary care university hospital, this study adopts an observational retrospective cohort design. The study included adult patients with acute respiratory symptoms diagnosed with influenza using rapid antigen testing. The cohort was divided into single and recurrent ED visitors based on revisits within 10 days of initial discharge. A comparative analysis was performed, evaluating demographics, laboratory parameters, and clinical process data between recurrent visitors and single visitors.

Results

Among 218 patients, 36.2% (n = 139) experienced recurrent ED visits. Age and gender disparities were not significant. Antibiotics were prescribed for 55.5% (n = 121) and antivirals for 92.7% (n = 202) of patients, with no notable influence on recurrence. Recurrent visitors exhibited lower monocyte counts, hemoglobin levels, higher PDW and P-LCR percentages, and increased anemia prevalence (p = 0.036, p = 0.01, p = 0.004, p = 0.029, p = 0.017, respectively). C-reactive protein (CRP) levels did not significantly affect recurrence.

Conclusion

This study highlights the pressing concern of recurrent ED visits among mild influenza patients, magnifying the challenges of ED overcrowding. The observed notable prescription rates of antibiotics and antivirals underscore the intricate landscape of influenza management. Diminished monocyte counts, hemoglobin levels, and altered platelet parameters signify potential markers for identifying patients at risk of recurrent visits.

Unscheduled emergency department presentations with diabetes: Identifying high risk characteristics

BACKGROUND

Unscheduled emergency department (ED) presentation by patients with diabetes has seldom been examined. This study aimed to determine the frequency and associated characteristics of presentations in this population.

METHODS

Using a prospective cross-sectional design, data were collected from patients with diabetes presenting and/or admitted to a tertiary metropolitan hospital in New South Wales, Australia (December 2016-September 2017). A screening interview including brief measures of cognitive and executive function, and clinical details from healthcare records were utilised; details around unscheduled presentations within 90 days were extracted. Independent associations with ED presentation were determined.

RESULTS

Unscheduled ED presentations were common; 35.4% had at least one within 90 days, and for 20.1% this occurred within 28 days. The screening tool contributed little towards identifying risk of unscheduled presentation. Those attending any community or outpatient follow-up appointment within the first 28 (OR 0.42, 95% CI 0.23-0.76; p = 0.004) or 90 days (OR 0.25; 0.13-0.47; p < 0.001) from the index presentation were less likely to present within that same period.

CONCLUSIONS

Findings indicated the magnitude of unscheduled ED presentation, care complexity and the value of targeted and timely follow-up. Alternative service support may help maintain and improve diabetes self-management and will require effectiveness and cost-effectiveness evaluation.

Factors Associated with Return Visits by Elders within 72 Hours of Discharge from the Emergency Department

Elders have a higher rate of return visits to the emergency department (ED) than other patients. It is critical to understand the risk factors for return visits to the ED by elders. The aim of this study was to determine the factors associated with return visits to the ED by elders. This study retrospectively reviewed the hospital charts of elders who returned to the ED within 72 h after discharge from ED. The risk factors identified in the Triage Risk Screening Tool were applied in this study. Of the elders discharged from the ED, 8.64% made a return visit to the ED within 72 h. The highest revisit rate occurred within 24 h after discharge. Factors associated with return ED visits within 24 h by elders were difficulty walking and having discharge care needs. The factor associated with ED return visits within 24-48 h was polypharmacy. Difficulty walking, having discharge care needs, and hospitalization within the past 120 days were associated with return visits made within 48-72 h following discharge. Identifying the reasons for return visits to the ED and providing a continuous review of geriatric assessment and discharge planning could reduce unnecessary revisits.

Clinical factors predicting return emergency department visits in chemotherapy-induced febrile neutropenia patients

BACKGROUND

Although chemotherapy-induced febrile neutropenia (FN) is the most common and life-threatening oncologic emergency, the characteristics and outcomes associated with return visits to the emergency department (ED) in these patients are uncertain. Hence, we aimed to investigate the predictive factors and clinical outcomes of chemotherapy-induced FN patients returning to the ED.

METHOD

This single-center, retrospective observational study spanning 14 years included chemotherapy-induced FN patients who visited the ED and were discharged. The primary outcome was a return visit to the ED within five days. We conducted logistic regression analyses to evaluate the factors influencing ED return visit.

RESULTS

This study included 1318 FN patients, 154 (12.1%) of whom revisited the ED within five days. Patients (53.3%) revisited the ED owing to persistent fever (56.5%), with no intensive care unit admission and only one mortality case who was discharged hopelessly. Multivariable analysis revealed that shock index >0.9 (odds ratio [OR]: 1.45, 95% confidence interval [CI], 1.01-2.10), thrombocytopenia (<100 × 10³/uL) (OR: 1.64, 95% CI, 1.11-2.42), and lactic acid level > 2 mmol/L (OR: 1.51, 95% CI, 0.99-2.25) were associated with an increased risk of a return visit to the ED, whereas being transferred into the ED from other hospitals (OR: 0.08; 95% CI, 0.005-0.38) was associated with a decreased risk of a return visit to the ED.

CONCLUSION

High shock index, lactic acid, thrombocytopenia, and ED arrival type can predict return visits to the ED in chemotherapy-induced FN patients.

A geriatric re-evaluation clinic is associated with fewer unplanned returns in the Emergency Department: an observational case-control study

PURPOSE

The increasing share of older adults is associated with heavier Emergency Health Services utilization. In this context, a significant problem is the rate of unplanned revisits of geriatric patients after discharge from the Emergency Department (ED). We aimed to evaluate whether the referral to a dedicated Geriatric Revaluation Clinic (GRC) after discharge from the ED is associated with fewer early unplanned returns.

METHODS

We conducted an observational, retrospective, case-control study comparing patients 65 years or older evaluated in a GRC after an ED visit and a control group of same age subjects accessing the ED during the study period and discharged with one of the ICD-9-CM diagnoses used for the cases, for whom defined post-ED assessment was not arranged. The intervention at the GRC consisted of a comprehensive geriatric evaluation. We calculated unadjusted and adjusted OR for unplanned ED revisits within 30 days from ED discharge using two logistic regression models including the variables with statistically significant differences among study groups at univariate analysis.

RESULTS

During the study period, 121 eligible patients were evaluated at the GRC and were matched to 242 subjects included in the control group. The median age of the study population was 85 years. The adjusted OR for unplanned return after ED discharge and unplanned hospital admission after ED discharge were 0.44 (CI 0.20-0.89) and 0.52 (CI 95% 0.18-1.74), respectively.

CONCLUSIONS

In a population of older patients discharged from the ED, the referral to a GRC is associated with fewer early unplanned revisits.

Multiple Electronic Health Record-Based Measures of Social Determinants of Health to Predict Return to the Emergency Department Following Discharge

Health care systems continue to struggle with preventing 30-day readmissions to their institutions. Social determinants of health (SDOH) are important predictors of repeat visits to the hospital. In many health systems, SDOH data are limited to those variables that are most relevant to care delivery or payment (eg, race, gender, insurance status). Despite calls for integrating a more robust set of measures (eg, measures of health behaviors and living conditions) into the electronic health record (EHR), these data often have missing values necessitating the use of imputation to build a comprehensive picture of patients who are likely to return to the health system. Using logistic regression analyses and imputation of missing data from 2017 to 2018, this study uses measures found in the EHR (eg, tobacco use, living situation, problems at home, education) to assess those SDOH that might predict a return to the emergency department within 30 days of discharge from a health system. In both imputed and raw data, the total number of recorded health conditions was the most important predictor and collectively SDOH variables made a relatively small contributions in determining the likelihood of a return to the hospital. Although SDOH variables might be important in the design of programs aimed at preventing readmissions, they may not be useful in readmission predictive models.

Emergency department-to-community care transition barriers: A qualitative study of older adults

BACKGROUND

Over one-half of older adults are discharged to the community after emergency department (ED) visits, and studies have shown there is increased risk of adverse health outcomes in the immediate post-discharge period. Understanding the experiences of older adults during ED-to-community care transitions has the potential to improve geriatric emergency clinical care and inform intervention development. We therefore sought to assess barriers experienced by older adults during ED-to-community care transitions.

METHODS

We conducted a qualitative analysis of community-dwelling cognitively intact patients aged 65 years and older receiving care in four diverse EDs from a single U.S. healthcare system. We constructed a conceptual framework a priori to guide the development and iterative revision of a codebook, used purposive sampling, and conducted recorded, semi-structured interviews using a standardized guide. Two researchers coded the professionally transcribed data using a combined deductive and inductive approach and analyzed transcripts to identify dominant themes and representative quotations.

RESULTS

Among 25 participants, 20 (80%) were women and 17 (68%) were white. We identified four barriers during the ED-to-community care transition: (1) ED discharge process was abrupt with missing information regarding symptom explanation and performed testing, (2) navigating follow-up outpatient clinical care was challenging, (3) new physical limitations and fears hinder performance of baseline activities, and (4) major and minor ramifications for caregivers impact an older adult's willingness to request or accept assistance.

CONCLUSIONS

Older adults identified barriers to successful ED-to-community care transitions that can inform the development of novel and effective interventions.

Cost variation and revisit rate for adult patients with asthma presenting to the emergency department

BACKGROUND

Asthma is common, resulting in 53 million emergency department (ED) visits annually. Little is known about variation in cost and quality of ED asthma care.

STUDY OBJECTIVE

We sought to describe variation in costs and 7-day ED revisit rates for asthma care across EDs. Our primary objective was to test for an association between ED costs and the likelihood of a 7-day revisit for another asthma exacerbation.

METHODS

We used the 2014 Florida State Emergency Department Database to perform an observational study of ED visits by patients ≥18 years old with a primary diagnosis of asthma that were discharged home. We compared patient and hospital characteristics of index ED discharges with and without 7-day revisits, then tested the association between ED revisits and index ED costs. Multilevel regression was performed to account for hospital-level clustering.

RESULTS

In 2014, there were 54,060 adult ED visits for asthma resulting in discharge, and 1667 (3%) were associated with an asthma-related ED revisit within 7 days. Median cost for an episode of ED asthma care was $597 with an interquartile range of $371-980. After adjusting for both patient and hospital characteristics, lack of insurance was associated with higher odds of revisit (OR 1.42, 95% CI 1.18-1.71), while private insurance, female gender, and older age were associated with lower odds of revisit. Hospital costs were not associated with ED revisits (OR = 1.00; 95% CI 1.00-1.00).

CONCLUSION

Hospital costs associated with ED asthma visits vary but are not associated with odds of ED revisit.

Overcrowding in Emergency Department: Causes, Consequences, and Solutions—A Narrative Review

Overcrowding in Emergency Departments (EDs) is a phenomenon that is now widespread globally and causes a significant negative impact that goes on to affect the entire hospital. This contributes to a number of consequences that can affect both the number of resources available and the quality of care. Overcrowding is due to a number of factors that in most cases lead to an increase in the number of people within the ED, an increase in mortality and morbidity, and a decrease in the ability to provide critical services in a timely manner to patients suffering from medical emergencies. This phenomenon results in the Emergency Department reaching, and in some cases exceeding, its optimal capacity. In this review, the main causes and consequences involving this phenomenon were collected, including the effect caused by the SARS-CoV-2 virus in recent years. Finally, special attention was paid to the main operational strategies that have been developed over the years, strategies that can be applied both at the ED level (microlevel strategies) and at the hospital level (macrolevel strategies).

Pediatric Return Visits to the Emergency Department: The Time to Return Curve

OBJECTIVE

Although 72-hour return visits are a frequently reported metric for pediatric patients discharged from the emergency department (ED), the basis for this metric is not established. Our objective was to statistically derive a cutoff time point for the characterization of pediatric return visits.

METHODS

We performed a retrospective cohort study using data of patients discharged from any of 44 pediatric EDs. We selected the first encounter per patient from January 1 to December 31, 2019, as the index encounter and included the first return visit within 30 days. We constructed a cumulative hazard curve to characterize the timing of return visits and constructed a multivariable adaptive regression spline model to identify a hinge point in return visit presentations. We identified the association between admission for early return visits and admission for late return visits using generalized linear mixed modeling.

RESULTS

Of 1,986,778 index ED discharges, 193,605 (9.7%) ED return visits were included. A double-exponential decay model demonstrated superior fit compared with a single exponential model ( P < 0.0001). Multivariable adaptive regression spline modeling identified a hinge at 7 days. When comparing proportions of return visits leading to hospitalization between early (23.8%) and late (15.1%) return visits, early visits (≤7 days) had higher adjusted odds of hospital admission (adjusted odds ratio, 1.73; 95% confidence interval, 1.69-1.77) relative to late return visits (>7 days). Findings were similar in sensitivity analyses within age subgroups, Census region, and in which the diagnosis (using the Diagnosis and Grouping System) was the same between the index and return visit. Among return visits that occurred within 7 days of the index visit, 46.3% had the same diagnosis grouping in both visits.

CONCLUSIONS

An empirically derived 7-day cutoff may be more appropriate for characterization of pediatric return visits to the ED. Encounters after this period had lower adjusted odds of admission.

A Comparison of Emergency Department Revisit Rates of Pediatric Patients between Pre-COVID-19 and COVID-19 Periods

Unscheduled revisits to emergency departments (EDs) are important because they indicate the quality of emergency care. However, the characteristics of pediatric patients visiting EDs changed during the coronavirus disease (COVID-19) pandemic, and these changes may have affected their revisit patterns. Therefore, we aimed to compare the ED revisit patterns of pediatric patients between the pre-COVID-19 and COVID-19 periods. This retrospective multicenter study included patients aged below 18 years who visited the ED in the pre-COVID-19 and COVID-19 periods. ED revisit rates were analyzed using five age groups and three visit-revisit intervals. In the pre-COVID-19 period, the revisit rates decreased with increasing age. In the COVID-19 period, the revisit rates were the lowest for the group aged 4–6 years, and the rates increased for those aged ≥7 years. In conclusion, there were changes in the patterns of revisit rates of pediatric patients according to age between the pre-COVID-19 and COVID-19 periods. Therefore, it is necessary to identify the reasons for revisits according to age and establish strategies to reduce the revisit rates of pediatric patients.

Intravenous antibiotics at the index emergency department visit as an independent risk factor for hospital admission at the return visit within 72 hours

Introduction

Although infection was the most common symptom in patients returning to the ED, whether intravenous antibiotic administration at the index visit could serve as an indicator of patients with infectious diseases at high risk for hospital admission after returning to the ED within a short period of time remains unclear. The study aimed to investigate the potential risk factors for hospital admission in patients returning to the ED within 72 hours with a final diagnosis of infectious diseases.

Material and methods

This retrospective cohort study analyzed return visits to the ED from January to December 2019. Adult patients aged >20 years who had a return visit to the ED within 72 hours with an infectious disease were included herein. In total, 715 eligible patients were classified into the intravenous antibiotics and non-intravenous antibiotics group (reference group). The outcome studied was hospital admission to general ward and intensive care unit (ICU) at the return visits.

Results

Patients receiving intravenous antibiotics at index visits had significantly higher risk—approximately two times—for hospital admission at the return visits than those did not (adjusted odds ratio = 2.47, 95% CI = 1.34–4.57, p = 0.004). For every 10 years increase in age, the likelihood for hospital admission increased by 38%. Other factors included abnormal respiratory rate and high C-reactive protein levels.

Conclusions

Intravenous antibiotic administration at the index visit was an independent risk factor for hospital admission at return visits in patients with an infection disease. Physicians should consider carefully before discharging patients receiving intravenous antibiotics.

Access to post-acute care services reduces emergency department utilisation among individuals insured by Medicaid: An observational study

AIMS AND OBJECTIVES

We examined whether access to post-acute care services differed between individuals insured by Medicaid and commercial insurers and whether those differences explained emergency department utilisation 30 days post-hospitalisation.

BACKGROUND

Timely follow-up to community-based providers is a strategy to improve post-hospitalisation outcomes. However, little is known regarding the influence of post-acute care services on the likelihood of emergency department use post-hospitalisation for individuals insured by Medicaid.

DESIGN

We conducted a retrospective observational study of electronic health record data from an academic medical centre in a large northeastern urban setting. The STROBE checklist was used in reporting this observational study.

METHODS

Our analysis included adults insured by Medicaid or commercial insurers who were discharged from medical services between 1 August-31 October 2017 (n = 785). Logistic regression models were used to examine the effects of post-acute care services (primary care, home health, specialty care) on the odds of an emergency department visit.

RESULTS

Post-hospitalisation, 12% (n = 59) of individuals insured by Medicaid experienced an emergency department visit compared to 4.2% (n = 13) of individuals commercially insured. Having Medicaid insurance was associated with higher odds of emergency department visits post-hospitalisation (OR = 3.24). Having a home care visit or specialty care visit within 30 days post-discharge were significant predictors of lower odds of emergency department visits. Specific to specialty care visits, Medicaid was no longer a significant predictor of emergency department visits with specialty care being more influential (OR = 0.01).

CONCLUSIONS

Improving connections to appropriate post-acute care services, specifically specialty care, may improve outcomes among individuals insured by Medicaid.

RELEVANCE TO CLINICAL PRACTICE

Hospital-based nurses, including those in direct care, case management and discharge planning, play an important role in facilitating referrals and scheduling appointments prior to discharge. Individuals insured by Medicaid may require additional support in accessing these services and nurses are well-positioned to facilitate care continuity.

UNPLANNED REPRESENTATION TO HOSPITAL BY PATIENTS WITH DIABETES: DEVELOPMENT AND PILOT FEASIBILITY TESTING OF A SCREENING TOOL

BackgroundUnplanned representation of patients with diabetes recently discharged from emergency department or in-patient hospitals is a common but complex problem worldwide. This study set out to examine the feasibility of a risk screening interview and whether component characteristics may be associated with unplanned representation of patients with diabetes to a tertiary metropolitan hospital.MethodsA screening interview comprised of demographic, social and clinical characteristics was developed and piloted using prospective cross-sectional survey design. A convenience sample of 55 patients was recruited and screened. Outcomes were the occurrence of unplanned representation to hospital within 28 or 90 days of hospital discharge from the index presentation.ResultsThe screening interview was shown to be broadly feasible and acceptable for use by staff and patients, with identified areas for modification. Seventeen participants (30.9%) experienced unplanned representation within 90 days of hospital discharge; for 13 participants (23.6%) this occurred within 28 days. Characteristics linked with unplanned representation to hospital were identified.ConclusionsPreliminary data indicated the feasibility of tool use and informed refinement for future testing of the ability of the screening interview to predict those patients with diabetes at high risk of unplanned representation to hospital to enhance effective care planning.

Effects of Maryland's global budget revenue model on emergency department utilization and revisits

BACKGROUND

In 2014, Maryland (MD) implemented a "global budget revenue" (GBR) program that prospectively sets hospital budgets. This program introduced incentives for hospitals to tightly control volume and meet budget targets. We examine GBR's effects on emergency department (ED) visits, admissions, and returns.

METHODS

We performed an interrupted time-series analysis with difference-in-differences comparisons using 2012 to 2015 Healthcare Cost Utilization and Project data from MD, New York (NY), and New Jersey (NJ). We examined GBR's effects on ED visits/1,000 population, admissions from the ED, and ED returns at 72 h and 9 days. We also examined rates of admission, intensive care unit (ICU) stay, and in-hospital mortality among returns. To evaluate racial/ethnic and payer outcome disparities among ED returns, we performed a triple differences analysis.

RESULTS

ED visits decreased with GBR adoption in MD relative to NY and NJ, by five and six visits/1,000 population, respectively. ED admissions declined relative to NY and NJ, by 0.6% and 1.8%, respectively. There was also a post-GBR decline in ED returns by 0.7%. Admissions among returns declined by 2%, while ICU and in-hospital mortality among returns remained relatively stable. ED return outcomes varied by racial/ethnic and payer group. Non-Hispanic Whites and non-Hispanic Blacks experienced a similar decline in returns, while returns remained unchanged among Hispanics/Latinos, widening the disparity gap. Payer group disparities between privately insured and Medicare, Medicaid, and uninsured individuals improved, with the disparity reduction most pronounced among the uninsured.

CONCLUSIONS

GBR adoption was associated with lower ED utilization and admissions. ED returns and admissions among returns also decreased, while mortality and ICU stays among returns remained stable, suggesting that GBR has not led to adverse patient outcomes from fewer admissions. However, changes in ED return disparities varied by subgroup, indicating that improvements in care transitions may be uneven across patient populations.

Clinician perspectives on reasons for, implications and management of unplanned patient returns to the Emergency Department: A descriptive study

BACKGROUND

Unplanned return visits to the emergency department (ED) have been associated with adverse outcomes and may reflect the quality of care delivered. Several studies speculate the reasons for return and suggest clinician behaviour as potentially influencing a patient's decision to return to the ED. There is little research about this issue from the clinician's perspective, which is necessary to inform future practice improvement.

METHODS

A descriptive cross sectional design was employed to ascertain perspectives on identification and management of return visits occurring within 48 hours of discharge. An electronic survey was distributed to all medical, nursing, and clerical staff at one ED. Descriptive statistics were used for quantitative data and content analysis was performed on textual data. Results were categorised as barriers or facilitators, then mapped to the Theoretical Domains Framework.

RESULTS

A response rate of 59.7% (n=86/144) was achieved. Staff reported increased levels of concern for this patient group but not all staff were aware of the policy for managing return patients (40.7%). Five barriers and three facilitators were identified that mapped to eight influencers of behaviour including knowledge, memory and environmental factors.

CONCLUSION

Overall, staff were aware of return patients but lacked familiarity with policy and processes to identify and commence relevant protocols. Further review of current practice as well as the patient perspective is required before any intervention to improve practice is developed.

Odds of return: a prospective study using provider assessment to predict short-term patient return visits to the emergency department

OBJECTIVE

Previous studies have assessed patient-level characteristics associated with emergency department (ED) return visits, but none have used provider assessment. We prospectively investigate whether clinical providers could accurately predict ED return visits.

METHODS

Prospective cohort study.

SETTING

Single academically affiliated urban county hospital.

PARTICIPANTS

Discharged ED patients over a 14-month period with a provider assessment of the likelihood of patient return within 7 days of ED discharge.

MAIN OUTCOME MEASURES

The primary outcome of interest was a return visit to the ED within 7 days. Additional outcome measures included a return visit within 72 hours and a return visit resulting in admission. We also measured the accuracy of provider gestalt, and provide measures of sensitivity, specificity, predictive values, and likelihood ratios.

RESULTS

Of the 11 922 ED discharges included in this study, providers expected 2116 (17.7%) to result in a return visit within 7 days. Providers were much more likely to perceive a return visit if the patient left against medical advice (OR: 5.97, 95% CI: 4.67 to 7.62), or was homeless (OR: 5.69, 95% CI: 5.14 to 6.29). Patients who actually returned were also more likely to be homeless, English speaking and to have left the ED against medical advice on the initial encounter. The strongest predictor of a return visit at both 72 hours and 7 days in multivariable modelling was provider assessment (OR: 3.77, 95% CI: 3.25 to 4.37; OR: 3.72, 95% CI: 3.29 to 4.21, respectively). Overall sensitivity and specificity of provider gestalt as a measure of patient return within 7 days were 47% and 87%, respectively. The positive and negative likelihood ratios were 3.51 and 0.61, respectively.

CONCLUSIONS

Clinician assessment was the strongest predictor of a return visit in this dataset. Clinician assessment may be used as a way to screen patients during the index visit and enrol them in efforts to decrease return visits.

The Parent Perspective on Return Visits to the Pediatric Emergency Department: A Missing Piece of the Puzzle

OBJECTIVES

Return visits to the pediatric emergency department (ED) give insight into the unmet needs of patients and families. The aim of this study was to capture the parent perspective on factors contributing to return visits to the pediatric ED.

METHODS

This is a prospective cohort study consisting of an 11-item survey that was administered to parents of children who had a return visit to the ED less than 72 hours from their initial visit. Surveys were distributed over an 8-month period between November 2015 and June 2016.

RESULTS

The primary reason parents report for returning to the ED is that their child had ongoing or worsening symptoms (55%). Parents were satisfied with the care they received at the initial ED visit (89% report excellent, very good or good care). For parents who report that the initial visit could have been improved, they report wanting more tests done (54%), a better follow-up plan arranged by the ED (31%), consultation with a specialist (26%), admission to hospital on the initial visit (26%), and better communication and more time spent with the ED physician (21%). The majority (97%) of parents reported that their child has a primary care provider, and 39% of parents brought their child to a health care provider for the same problem in the 7 days before their return visit to the ED.

CONCLUSIONS

The parent perspective gives important insights into the reasons for return visits to the pediatric ED. Conclusions from this study will help inform future quality improvement initiatives that direct health care resources to provide high value care to patients and families.

Care transitions and social needs: A Geriatric Emergency care Applied Research (GEAR) Network scoping review and consensus statement

OBJECTIVES

Individual-level social needs have been shown to substantially impact emergency department (ED) care transitions of older adults. The Geriatric Emergency care Applied Research (GEAR) Network aimed to identify care transition interventions, particularly addressing social needs, and prioritize future research questions.

METHODS

GEAR engaged 49 interdisciplinary stakeholders, derived clinical questions, and conducted searches of electronic databases to identify ED discharge care transition interventions in older adult populations. Informed by the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) framework, data extraction and synthesis of included studies included the degree that intervention components addressed social needs and their association with patient outcomes. GEAR convened a consensus conference to identify topics of highest priority for future care transitions research.

RESULTS

Our search identified 248 unique articles addressing care transition interventions in older adult populations. Of these, 17 individual care transition intervention studies were included in the current literature synthesis. Overall, common care transition interventions included coordination efforts, comprehensive geriatric assessments, discharge planning, and telephone or in-person follow-up. Fourteen of the 17 care transition intervention studies in older adults specifically addressed at least one social need within the PRAPARE framework, most commonly related to access to food, medicine, or health care. No care transition intervention addressing social needs in older adult populations consistently reduced subsequent health care utilization or other patient-centered outcomes. GEAR stakeholders identified that determining optimal outcome measures for ED-home transition interventions was the highest priority area for future care transitions research.

CONCLUSIONS

ED care transition intervention studies in older adults frequently address at least one social need component and exhibit variation in the degree of success on a wide array of health care utilization outcomes.

Experiences and perspectives of older patients with a return visit to the emergency department within 30 days: patient journey mapping

Aim

To achieve patient-centered care for older patients at the emergency department (ED) it is important to include their perspective and experience, and this can be done through the patient journey method.

Findings

By mapping the patient journey, we found that waiting times and suboptimal discharge communication are almost always related to a negative experience for older patients.

Message

The novelty of this study lies within the qualitative patient journey method, which allowed us to include the voice of the patient in issues that have been previously described (i.e. waiting times and discharge communication). We believe this can guide towards patient-centered improvement initiatives that can contribute to a positive ED experience in the future, for example a time-out at the ED and a discharge check list

Supplementary Information

The online version contains supplementary material available at 10.1007/s41999-021-00581-6.

Purpose

Up to 22% of older patients who visit the emergency department (ED) have a return visit within 30 days. To achieve patient-centered care for this group at the ED it is important to involve the patient perspective and strive to provide the best possible experience. The aim of this study was to gain insight into the experiences and perspectives of older patients from initial to return ED visit by mapping their patient journey.

Methods

We performed a qualitative patient journey study with 13 patients of 70 years and older with a return ED visit within 30 days who presented at the Amsterdam UMC, a Dutch academic hospital. We used semi-structured interviews focusing on the patient experience during their journey and developed a conceptual framework for coding.

Results

Our sample consisted of 13 older patients with an average age of 80 years, and 62% of them were males. The framework contained a timeline of the patient journey with five chronological main themes, complemented with an ‘experience’ theme, these were divided into 34 subthemes. Health status, social system, contact with the general practitioner, aftercare, discharge and expectations were the five main themes. The experiences regarding these themes differed greatly between patients. The two most prominent subthemes were waiting time and discharge communication, which were mostly related to a negative experience.

Conclusions

This study provides insight into the experiences and perspectives of older patients from initial to return ED visit. The two major findings were that lack of clarity regarding waiting times and suboptimal discharge communication contributed to negative experiences. Recommendations regarding waiting time (i.e. a two-hour time out at the ED), and discharge communication (i.e. checklist for discharge) could contribute to a positive ED experience and thereby potentially improve patient-centered care.

90-Day Return Visit to the Emergency Department After an Initial Neurosurgical Evaluation

OBJECTIVE

This study evaluated emergency department (ED) neurosurgical reevaluation rates and their causes. Identifying the most significant reasons that make patients return to the ED for a neurosurgical reevaluation can help implement changes to reduce the economic and medical burden of patient turnover.

METHODS

All patients undergoing neurosurgical reevaluation at our institution's ED after an initial neurosurgical evaluation were enrolled in a prospective 3-month longitudinal registry. Inclusion criteria were all adult patients 21 years of age or older previously evaluated by neurosurgery at our institution's ED who return within 90 days for a neurosurgical reevaluation.

RESULTS

We found an overall 90-day ED neurosurgical return visit rate of 2.1%. During the study, 34 patients returned to the ED for a neurosurgical reevaluation. Patients returned for a neurosurgical reevaluation at a median of 23.5 days after the initial neurosurgery evaluation. The principal causes for a return visit were altered mental status, headache, and wound infections. Among the returning patients, 59% required hospitalization and 50% required an operation.

CONCLUSIONS

To our knowledge, this is the first study to prospectively collect data to estimate the 90-day ED return visit rate for a neurosurgical reevaluation following an initial ED neurosurgical evaluation. Some patients still use the ED to get continued care of their condition despite having access to their primary care physician. Better communication, social worker coordination, and prompt follow-up appointments at the neurosurgical outpatient clinic may reduce return visits.

Risk Factors for Early Return Visits to the Emergency Department in Patients Presenting with Nonspecific Abdominal Pain and the Use of Computed Tomography Scan

Over a quarter of patients presenting with abdominal pain at emergency departments (EDs) are diagnosed with nonspecific abdominal pain (NSAP) at discharge. This study investigated the risk factors associated with return ED visits in Taiwanese patients with NSAP after discharge. We divided patients into two groups: the study group comprising patients with ED revisits after the index ED visit, and the control group comprising patients without revisits. During the study period, 10,341 patients discharged with the impression of NSAP after ED management. A regression analysis found that older age (OR [95%CI]: 1.007 [1.003–1.011], p = 0.004), male sex (OR [95%CI]: 1.307 [1.036–1.650], p = 0.024), and use of NSAIDs (OR [95%CI]: 1.563 [1.219–2.003], p < 0.001) and opioids (OR [95%CI]: 2.213 [1.643–2.930], p < 0.001) during the index visit were associated with increased return ED visits. Computed tomography (CT) scans (OR [95%CI]: 0.605 [0.390–0.937], p = 0.021) were associated with decreased ED returns, especially for those who were older than 60, who had an underlying disease, or who required pain control during the index ED visit.

Occupational Therapy in the Emergency Department: Patient Frailty and Unscheduled Return Visits

Background. Occupational therapy facilitates care for complex frail emergency department (ED) patients who may have unscheduled return visits (URVs). Purpose. To determine the prevalence of frailty amongst ED patients referred to occupational therapy and if frailty affected the rates and reasons for URVs. Methods. A mixed-methods health records review was conducted of older adults referred to an ED-based occupational therapy program. Findings. Most patients were frail (60.6%). 31.0% of patients discharged home had a URV within 30 days, with no difference in URV rates between frail and non-frail populations. Providing occupational therapy education reduced the frequency of URVs. Frail patients had complex reasons for their URVs, including functional, social/environmental, safety concerns, and/or "failure to thrive". Occupational therapy ED patients were typically vulnerable to moderately frail, dependent in some activities of daily living, and complex. Implications. ED-based occupational therapists must be aware of their patient's frailty and risk of URVs.

A Descriptive Study of Emergency Department Visits Within 30 Days of Discharge

BACKGROUND

Unnecessary emergency department (ED) visits are a crucial consideration in discharge planning for acutely admitted patients. This study aimed to identify the reasons for unnecessary visits to the ED within 30 days of discharge from a medical hospitalist unit.

METHODS

We performed a retrospective review of patients discharged in 2018 from a medical unit of tertiary teaching hospital in Korea. The authors discussed in-depth and determined whether or not an ED visit was unnecessary, and further classified the causes of unnecessary visits into three categories.

RESULTS

The mean age of the patients was 62.9 years (range, 15-99 years), and among the 1,343 patients discharged from the unit, 720 (53.6%) were men. Overall, 215 patients (16.0%) visited the ED within 30 days after discharge; among them, 16.3% were readmitted. Of the 215 cases of ED visits within 30 days after discharge, 57 (26.5%) were considered unnecessary. Of these, 30 (52.6%) were categorized as having failed care transition, 15 (26.3%) had unestablished care plans for predictable issues, and 12 (21.1%) had insufficient patient education.

CONCLUSION

A substantial number of short-term ED visits by discharged multimorbid or older medical patients were considered unnecessary. Discharging patients with a thorough discharge plan is essential to avoid unnecessary ED visits.

Factors associated with a high-risk return visit to the emergency department: a case-crossover study

BACKGROUND AND IMPORTANCE

Although factors related to a return emergency department (ED) visit have been reported, few studies have examined 'high-risk' return ED visits with serious adverse outcomes. Understanding factors associated with high-risk return ED visits may help with early recognition and prevention of these catastrophic events.

OBJECTIVES

We aimed to (1) estimate the incidence of high-risk return ED visits, and (2) to investigate time-varying factors associated with these revisits.

DESIGN

Case-crossover study.

SETTINGS AND PARTICIPANTS

We used electronic clinical warehouse data from a tertiary medical center. We retrieved data from 651 815 ED visits over a 6-year period. Patient demographics and computerized triage information were extracted.

OUTCOME MEASURE AND ANALYSIS

A high-risk return ED visit was defined as a revisit within 72 h of the index visit with ICU admission, receiving emergency surgery, or with in-hospital cardiac arrest during the return ED visit. Time-varying factors associated with a return visit were identified.

MAIN RESULTS

There were 440 281 adult index visits, of which 19 675 (4.5%) return visits occurred within 72 h. Of them, 417 (0.1%) were high-risk revisits. Multivariable analysis showed that time-varying factors associated with an increased risk of high-risk revisits included the following: arrival by ambulance, dyspnea, or chest pain on ED presentation, triage level 1 or 2, acute change in levels of consciousness, tachycardia (>90/min), and high fever (>39°C).

CONCLUSIONS

We found a relatively small fraction of discharges (0.1%) developed serious adverse events during the return ED visits. We identified symptom-based and vital sign-based warning signs that may be used for patient self-monitoring at home, as well as new-onset signs during the return visit to alert healthcare providers for timely management of these high-risk revisits.

Inpatient Outcomes Following a Return Visit to the Emergency Department: A Nationwide Cohort Study

Introduction

Emergency department (ED) revisits are traditionally used to measure potential lapses in emergency care. However, recent studies on in-hospital outcomes following ED revisits have begun to challenge this notion. We aimed to examine inpatient outcomes and resource use among patients who were hospitalized following a return visit to the ED using a national database.

Methods

This was a retrospective cohort study using the National Health Insurance Research Database in Taiwan. One-third of ED visits from 2012–2013 were randomly selected and their subsequent hospitalizations included. We analyzed the inpatient outcomes (mortality and intensive care unit [ICU] admission) and resource use (length of stay [LOS] and costs). Comparisons were made between patients who were hospitalized after a return visit to the ED and those who were hospitalized during the index ED visit.

Results

Of the 3,019,416 index ED visits, 477,326 patients (16%) were directly admitted to the hospital. Among the 2,504,972 patients who were discharged during the index ED visit, 229,059 (9.1%) returned to the ED within three days. Of them, 37,118 (16%) were hospitalized. In multivariable analyses, the inpatient mortality rates and hospital LOS were similar between the two groups. Compared with the direct-admission group, the return-admission group had a lower ICU admission rate (adjusted odds ratio, 0.78; 95% confidence interval [CI], 0.72–0.84), and lower costs (adjusted difference, −5,198 New Taiwan dollars, 95% CI, −6,224 to −4,172).

Conclusion

Patients who were hospitalized after a return visit to the ED had a lower ICU admission rate and lower costs, compared to those who were directly admitted. Our findings suggest that ED revisits do not necessarily translate to poor initial care and that subsequent inpatient outcomes should also be considered for better assessment.

Outcomes for Patients with Urinary Tract Infection After an Initial Intravenous Antibiotics Dose Before Emergency Department Discharge

INTRODUCTION

To investigate the effect of single-dose intravenous antibiotics before emergency department (ED) discharge on the outcomes of patients with urinary tract infections (UTIs).

METHODS

This is a retrospective study conducted at the EDs of three medical centers. Patients aged over 18 years who presented to the ED with UTI and were discharged without admission between January 1, 2016 and December 31, 2017 were evaluated. The study group received a single dose of effective intravenous antibiotics on the basis of urine culture during the index ED visit following oral antibiotics, while the comparison group received oral antibiotics only. The primary outcomes were ED revisit within 72 h and admission following the return visit.

RESULTS

A total of 8168 patients were included. Of these, 20.9% received intravenous antibiotics before ED discharge. Patients who received effective intravenous antibiotics before ED discharge were associated with less than 72-h ED revisit (adjusted odds ratio [OR] 0.791, 95% confidence interval [CI] 0.640-0.979]), but not decreased admission following the return visit (adjusted OR 0.921, 95% CI [0.731-1.153]). In subgroup analysis, parenteral antibiotic use during the index ED visit was associated with decreased admission following ED revisit in patients who presented with fever (adjusted OR 0.605; 95% CI 0.443-0.932).

CONCLUSION

For patients with UTI and clinically well to be discharged from the ED, a single dose of effective intravenous antibiotics before ED discharge was associated with decreased 72-h ED revisit. In patients with febrile UTI, initial intravenous antibiotics were associated with decreased revisit leading to admissions.

Comparing Pediatric Gastroenteritis Emergency Department Care in Canada and the United States

BACKGROUND

Between-country variation in health care resource use and its impact on outcomes in acute care settings have been challenging to disentangle from illness severity by using administrative data.

METHODS

We conducted a preplanned analysis employing patient-level emergency department (ED) data from children enrolled in 2 previously conducted clinical trials. Participants aged 3 to <48 months with <72 hours of gastroenteritis were recruited in pediatric EDs in the United States (N = 10 sites; 588 participants) and Canada (N = 6 sites; 827 participants). The primary outcome was an unscheduled health care provider visit within 7 days; the secondary outcomes were intravenous fluid administration and hospitalization at or within 7 days of the index visit.

RESULTS

In adjusted analysis, unscheduled revisits within 7 days did not differ (adjusted odds ratio [aOR]: 0.72; 95% confidence interval (CI): 0.50 to 1.02). At the index ED visit, although participants in Canada were assessed as being more dehydrated, intravenous fluids were administered more frequently in the United States (aOR: 4.6; 95% CI: 2.9 to 7.1). Intravenous fluid administration rates did not differ after enrollment (aOR: 1.4; 95% CI: 0.7 to 2.8; US cohort with Canadian as referent). Overall, intravenous rehydration was higher in the United States (aOR: 3.8; 95% CI: 2.5 to 5.7). Although hospitalization rates during the 7 days after enrollment (aOR: 1.1; 95% CI: 0.4 to 2.6) did not differ, hospitalization at the index visit was more common in the United States (3.9% vs 2.3%; aOR: 3.2; 95% CI: 1.6 to 6.8).

CONCLUSIONS

Among children with gastroenteritis and similar disease severity, revisit rates were similar in our 2 study cohorts, despite lower rates of intravenous rehydration and hospitalization in Canadian-based EDs.

Predictors and outcomes of patients that return unplanned to the Emergency Department and require critical care admission: A multicenter study

OBJECTIVE

To determine the incidence, characteristics (including timeframe) and predictors of patients discharged from the Emergency Department (ED) that later return and require admission.

METHODS

A retrospective cross-sectional study examining all return visits to three EDs in Sydney, Australia, over a 12-month period. Patients returning within 28 days from ED discharge with the same or similar complaint were classified as a return visit to ensure capture of all return visits. Descriptive and inferential statistics were used to analyse the data and logistic regression was performed to predict factors associated with return visits with general admission, and return visits admitted to critical care.

RESULTS

There were 1,798 (30%) return visits which resulted in admission, mostly to a non-critical care area (1,679, 93%). The current NSW 48 -h time frame used to define a return visit in NSW captured half of all admitted returns (49.5%) and just over half (59.2%) of critical care admissions. Variables associated with an admission to critical care were age (OR 1.02, 95% CI 1.01, 1.03), initial presentation (index visit) made to a lower level ED (OR 3.76 95% CI 2.06, 6.86), Triage Category 2 (OR 3.67 95% CI 2.04, 6.60) and a cardiac diagnosis (OR 5.76, 95% CI 3.01, 11.01). This model had adequate discriminant ability with AUROC = 0.825.

CONCLUSION

A small number of return visits result in admission, especially to critical care. These patients are at risk of poor outcomes. As such, clinicians should have increased index of suspicion for patients who return that are older, present with cardiac problems, or have previously presented to a lower level ED. Revision of the current timeframe that defines a return visit ought to be considered by policy makers to improve the accuracy of this widely used key performance indicator.

Higher Frequency of Undetected Acute Coronary Syndrome in Elderly Patients with Chest Pain Who Visited the Emergency Department: A Large-Cohort Retrospective Study

Background

Acute coronary syndrome (ACS) is a critical disease encountered in the emergency department (ED). Despite the development of diagnostic tools, it may be difficult to diagnose ACS because of atypical symptoms and equivocal test results. We investigated the difference in the rates of revisit and undetected ACS between adult and elderly patients who visited the ED with chest pain.

Method

Data from 11,323 patients who visited the ED with chest pain at university hospitals in Korea were retrospectively analyzed. The cohort was categorized into two age groups: the adult (30–64 years) and elderly (>65 years). Baseline characteristic data (age, sex, vital signs, triage category, etc.) were obtained. We selected patients who revisited the ED within 30 d and investigated whether ACS was diagnosed.

Result

The revisit rate was higher in the elderly (12%) than in the adult group (8.3%). The rate of undetected ACS among the revisited patients was 2.91% (18/7,186) in adults and 6.08% (16/1,998) in elderly patients.

Conclusion

Elderly patients with chest pain had an increased rate of ED revisits and undetected ACS than adult patients. We recommend that old patients should be hospitalized to observe the progression of cardiac complaints or receive short-term follow-up.

An Integrated Mobile Acute Care Service Enhances Value

Reducing the cost of care while enhancing its quality and experience are essential components to success in value-based care. Because emergency department (ED) and hospital settings represent high-cost environments, the authors sought to reduce their unnecessary use by deploying a novel care delivery service that offers mobile, on-demand care for high-acuity conditions in patient homes. This study is a retrospective quality improvement evaluation of the initial year of the mobile acute care model in a health system with a substantial penetration of value-based care. Although all patients were eligible for mobile services as clinically indicated, those in accountable care organizations were prioritized by the care management teams. A variety of operational, clinical, and financial metrics were assessed to determine the program's performance and value. There were 3436 patient encounters during the study period, a utilization rate of 71% that trended upward throughout the year. Of these visits, 44% involved patients in value-based payment models; 80% of these represented patients in Medicare risk agreements. Throughout the year, progressively improving operational and clinical performance were observed, as were consistently high patient satisfaction scores. An estimated 63.8% of total mobile visits resulted in ED avoidance; 21.6% were emergency medical transport avoidant; 14.1% led to avoided hospital observation or inpatient stays. Patients were highly satisfied with the service. In-home mobile care for high-acuity illness can prevent unnecessary ED and hospital use for some patients and is associated with high patient satisfaction. Acute mobile care is a useful component of a value-based care strategy.

Identifying patterns of health care utilisation among physical elder abuse victims using Medicare data and legally adjudicated cases: protocol for case-control study using data linkage and machine learning

INTRODUCTION

Physical elder abuse is common and has serious health consequences but is under-recognised and under-reported. As assessment by healthcare providers may represent the only contact outside family for many older adults, clinicians have a unique opportunity to identify suspected abuse and initiate intervention. Preliminary research suggests elder abuse victims may have different patterns of healthcare utilisation than other older adults, with increased rates of emergency department use, hospitalisation and nursing home placement. Little is known, however, about the patterns of this increased utilisation and associated costs. To help fill this gap, we describe here the protocol for a study exploring patterns of healthcare utilisation and associated costs for known physical elder abuse victims compared with non-victims.

METHODS AND ANALYSIS

We hypothesise that various aspects of healthcare utilisation are differentially affected by physical elder abuse victimisation, increasing ED/hospital utilisation and reducing outpatient/primary care utilisation. We will obtain Medicare claims data for a series of well-characterised, legally adjudicated cases of physical elder abuse to examine victims' healthcare utilisation before and after the date of abuse detection. We will also compare these physical elder abuse victims to a matched comparison group of non-victimised older adults using Medicare claims. We will use machine learning approaches to extend our ability to identify patterns suggestive of potential physical elder abuse exposure. Describing unique patterns and associated costs of healthcare utilisation among elder abuse victims may improve the ability of healthcare providers to identify and, ultimately, intervene and prevent victimisation.

ETHICS AND DISSEMINATION

This project has been reviewed and approved by the Weill Cornell Medicine Institutional Review Board, protocol #1807019417, with initial approval on 1 August 2018. We aim to disseminate our results in peer-reviewed journals at national and international conferences and among interested patient groups and the public.

Informing the development of a transitions of care program between an emergency department and regional supermarket chain pharmacies

OBJECTIVES

Pharmacist collaboration in transitions of care (TOC) programs is integral to increase patient education and adherence after discharge. This study aimed to conduct a qualitative evaluation of stakeholder perspectives to inform the design and implementation of a TOC program between an emergency department (ED) and regional supermarket chain pharmacies.

METHODS

Pharmacies from a regional supermarket chain were identified for inclusion on the basis of geographic proximity to a local community hospital ED. Semistructured, one-on-one interviews with the primary investigator were conducted. Interview questions were based on the Consolidation Framework for Implementation Research (CFIR). The following 5 CFIR domains were used: (1) intervention characteristics, (2) outer setting, (3) inner setting, (4) characteristics of individuals, and (5) process. Interviews were audio-recorded and transcribed. Two investigators coded each transcript independently. A thematic analysis was performed.

RESULTS

A total of 19 interviews were conducted, and the following 7 major themes emerged on analysis: (1) enhance real-time interprofessional communication, (2) establish data sharing between the ED and the community pharmacy, (3) provide timely resolution of prescription insurance issues for new therapies post-ED discharge, (4) use off-site pharmacy resources to support community pharmacy workflow, (5) increase patient education to prevent primary medication nonadherence, (6) reinforce discharge care plans, and (7) focus on community-dwelling older adult patients in an ED care transition program.

CONCLUSION

Health care providers including pharmacists, physicians, nurses, and care managers, view an ED-to-community pharmacy TOC program as a valuable service to increase patient education on new medications and discharge planning. Establishment of data sharing and reimbursement is integral to the development, implementation, and sustainability of such programs. There is an untapped opportunity for community pharmacists to bridge the gap in care after ED discharge.

Predictors of Older Adult Adherence With Emergency Department Discharge Instructions

OBJECTIVE

Older adults discharged from the emergency department (ED) are at high risk for adverse outcomes. Adherence to ED discharge instructions is necessary to reduce those risks. The objective of this study is to determine the individual-level factors associated with adherence with ED discharge instructions among older adult ED outpatients.

METHODS

We performed a secondary analysis of data from the control group of a randomized controlled trial testing a care transitions intervention among older adults (age ≥ 60 years) discharged home from the ED in two states. Taking data from patient surveys and chart reviews, we used multivariable logistic regression to identify patient characteristics associated with adherence to printed discharge instructions. Outcomes were patient-reported medication adherence, provider follow-up visit adherence, and knowledge of "red flags" (signs of worsening health requiring further medical attention).

RESULTS

A total 824 patients were potentially eligible, and 699 had data in at least one pillar. A total of 35% adhered to medication instructions, 76% adhered to follow-up instructions, and 35% recalled at least one red flag. In the multivariate analysis, no factors were significantly associated with failure to adhere to medications. Participants with poor health status (adjusted odds ratio [AOR] = 0.55, 95% confidence interval [CI] = 0.31 to 0.98) were less likely to adhere to follow-up instructions. Participants who were older (AORs trended downward as age category increased) or depressed (AOR = 0.39, 95% CI = 0.17 to 0.85) or had one or more functional limitations (AOR = 0.62, 95% CI = 0.41 to 0.94) were less likely to recall red flags.

CONCLUSION

Older adults discharged home from the ED have mixed rates of adherence to discharge instructions. Although it is thought that some subgroups may be higher risk than others, given the opportunity to improve ED-to-home transitions, EDs and health systems should consider providing additional care transition support to all older adults discharged home from the ED.

Ophthalmic Emergency Department Visits: Factors Associated With Loss to Follow-up

PURPOSE

To describe follow-up rates for patients referred for outpatient ophthalmic care after emergency department (ED) discharge and identify patient and visit characteristics associated with loss to follow-up (LTFU).

DESIGN

Single-institution retrospective cohort study.

METHODS

We analyzed the medical records of 2,206 patients seen in the ED for an eye-related issue who were subsequently scheduled for ophthalmology follow-up between 2013 and 2019 at a single tertiary health system. The main outcome measures were the frequency of and risk factors for LTFU and ED revisits.

RESULTS

In total, 1,649 (74.8%) patients completed follow-up within 2 months of an index ED visit. In multivariable analysis, younger age (P < .001), a nonurgent ophthalmic condition or nonophthalmic primary diagnosis (P < .001), scheduled follow-up >5 days after the ED visit (P < .001), additional follow-up appointments (<.001), no prior history of ophthalmology appointments (P = .045), a visual acuity of 20/40 or better (P = .027), and having Medicaid or being uninsured (P < .001) were significantly associated with LTFU. The presence of an interpreter significantly increased the likelihood of follow-up among non-English speaking patients (P < .001). LTFU was significantly associated with an ED revisit within 4 months of an index visit, and the ED revisit rate was significantly higher for patients LTFU vs those who completed follow-up (5.7% vs 1.1%; P < .001).

CONCLUSIONS

A quarter of patients referred for ophthalmic care after an ED presentation were LTFU. We identified numerous factors associated with LTFU that could be used to develop interventions to enhance follow-up. In addition, patients who were LTFU were more likely to revisit the ED for the same ophthalmic condition.

Nurse-Led Call Back Program to Improve Patient Follow-Up With Providers After Discharge From the Emergency Department

Phone calls to patients after discharge from the emergency department (ED) serve as reminders to schedule medical follow-up, support adherence to discharge instructions, and reduce revisits to already-crowded EDs. An existing, nurse-administered, call-back program contacted randomly selected ED patients 24 to 48 hours following discharge. This program did not improve patient follow-up (48.68%) nor reduce the ED revisit rate (6.7% baseline vs 6.0% postimplementation). Plan-Do-Study-Act methodology tested a modification to the existing program consisting of a second, scripted phone call from a trained volunteer at 72 to 96 hours postdischarge. Volunteers utilized a patient list and script, and nurses provided expertise to eliminate identified barriers to follow-up. Follow-up rate and ED revisit were monitored through the electronic medical record. A total of 894 patients participated between October 2017 and June 2018. Follow-up increased from 48.68% to 65.5% (P < .0001) and ED revisit decreased significantly (4.5% vs 8.6%, P < .001). This innovative nurse-led, systematic postdischarge call-back program utilizing hospital volunteers increased patient compliance with post-ED medical follow-up while significantly reducing the rate of patient revisit to the ED within 7 days of discharge.

Improving Quality of Care Through a Mandatory Provincial Audit Program: Ontario's Emergency Department Return Visit Quality Program

The Emergency Department Return Visit Quality Program was launched in Ontario, Canada, to promote a culture of quality. It mandates the province's largest-volume emergency departments (EDs) to audit charts of patients who had a return visit leading to hospital admission, including some of their 72-hour all-cause return visits with admission and all of their 7-day ones with sentinel diagnoses (ie, acute myocardial infarction, subarachnoid hemorrhage, and pediatric sepsis), and submit their findings to a governmental agency. This provides an opportunity to identify possible adverse events and quality issues, which hospitals can then address through quality improvement initiatives. A group of emergency physicians with quality improvement expertise analyzed the submitted audits and accompanying narrative templates, using a general inductive approach to develop a novel classification of recurrent quality themes. Since the Return Visit Quality Program launched in 2016, 125,698 return visits with admission have been identified, representing 0.93% of the 86 participating EDs' 13,559,664 visits. Overall, participating hospitals have conducted 12,852 detailed chart audits, uncovering 3,010 (23.4%) adverse events/quality issues and undertaking hundreds of quality improvement provincewide projects as a result. The inductive analysis revealed 11 recurrent themes, classified into 3 groupings: patient characteristics (ie, patient risk profile and elder care), ED team actions or processes (ie, physician cognitive lapses, documentation, handover/communication between providers, radiology, vital signs, and high-risk medications or medication interactions), and health care system issues (ie, discharge planning/community follow-up, left against medical advice/left without being seen, and imaging/testing availability). The Return Visit Quality Program is the largest mandatory audit program for EDs and provides a novel approach to identify local adverse events/quality issues to target for improved patient safety and quality of care. It provides a blueprint for health system leaders to enable clinicians to develop an approach to organizational quality, as well as for teams to construct an audit system that yields defined issues amenable to improvement.

Seventy-two-hour Return Initiative: Improving Emergency Department Discharge to Decrease Returns

Unscheduled return visits within 72 hours of discharge account for 4% of pediatric emergency department (ED) visits each year and are a quality indicator of ED care. This project aimed to reduce the unexpected 72-hour return visit rate for a network of ED and urgent cares (UC) by improving discharge processes.

The safety of home discharge for low-risk emergency department patients presenting with coronavirus-like symptoms during the COVID-19 pandemic: A retrospective cohort study

Objective

There is minimal evidence describing outcomes for emergency department (ED) patients with suspected coronavirus disease 2019 (COVID‐19) infection who are not hospitalized. The study objective was to assess 30‐day outcomes (ED revisit, admission, ICU admission, and death) for low‐risk patients discharged after ED evaluation for COVID‐19.

Methods

This was a retrospective cohort study of patients triaged to a COVID‐19 surge area within an urban ED and discharged between March 12 and April 6. Physicians were encouraged to discharge patients if they were well‐appearing with few comorbidities. Data were collected from review of medical records and phone follow‐up, and the analysis was descriptive.

Results

Of 452 patients, the median age was 38, and 61.7% had no comorbidities. Chest radiographs were performed for 50.4% of patients and showed infiltrates in 14% of those tested. Polymerase chain reaction testing was performed for 28.3% of patients during the index ED visit and was positive in 35.9% of those tested. Follow‐up was achieved for 75.4% of patients. ED revisits occurred for 13.7% of patients. The inpatient admission rate at 30 days was 4.6%, with 0.7% requiring intensive care. Median number of days between index ED evaluation and return for admission was 5 (interquartile range 3–7, range 1–17). There were no known deaths.

Conclusions

A minority of low‐risk patients with suspected COVID‐19 will require hospitalization after being discharged home from the ED. Outpatient management is likely safe for well‐appearing patients with normal vital signs, but patients should be instructed to return for worsening symptoms including labored breathing. Future work is warranted to develop and validate ED disposition guidelines.
