Facilitating Community Support Linkages for Frequent Emergency Department Users: The ENCOMPASS-ED Project

The ENCOMPASS-ED project implemented embedded health system navigation and mental health peer support to proactively engage frequent emergency department (ED) users, facilitate linkages to community services, and reduce ED overuse. This model of care is generalizable to other communities across Canada to support reductions in unnecessary and costly ED visits.

The health equity issues of an emergency department fee

In June 2021, the Swiss parliament accepted a legislative proposal calling for the introduction of a fee to fight emergency department (ED) overcrowding. Although this issue remains a major challenge for health policies, the introduction of such a fee raises many questions, notably regarding health equity. However, other more equitable solutions exist: improving the case management of ED frequent users and improving coordination between ED and primary care.

The receipt of information by family physicians about their patient\u2019s emergency department visits: a record linkage study of electronic medical records to health administrative data

BackgroundCanadians are known to be frequent users of emergency department (ED) care. However, the exchange of information from ED visits to family physicians (FPs) is not well known. Our objectives were to determine whether Canadian FPs received information about their patient’s ED visit and the patient characteristics related to the receipt of ED information.MethodsThis study was a descriptive record linkage study of FP Electronic Medical Record (EMR) data linked to health administrative data. Our study cohort included patients who had at least one ED visit in 2010 or 2015 in Ontario, Canada. An ED visit could include a transfer to or from another ED. The receipt of information from an ED note was examined in relation to patient age, sex, neighbourhood income quintiles, rurality and comorbidity.ResultsThere were 26,609 patients in 2010 and 50,541 patients in 2015 with at least one ED visit. In 2010, 53.3% of FPs received an ED note for patients having a single ED visit compared to 41.0% in 2015. For patients with multiple ED visits, 58.2% of FPs received an ED note in 2010 compared to 45.7% in 2015. FPs were more likely to receive an ED note for patients not living in low income neighbourhoods, older patients, patients living in small urban areas and for patients having moderate comorbidity. FPs were less likely to receive a note for patients living in rural areas.ConclusionsCommunity-based FPs are more likely to get information after an ED visit for their older and sicker patients. However, FPs do not receive any information from EDs for over half their patients. Electronic health record technologies and their adoption by ED providers need to improve the seamless transfer of information about the care provided in EDs to FPs in the community.

Characteristics of Pediatric Frequent Users of Emergency Departments in Alberta and Ontario.

Emergency department (ED) volumes have drawn attention to frequent users but less attention has been paid to children. This study examined sociodemographic and ED presentation characteristics of pediatric high-system ED users (HSUs) in 2 provinces in Canada. Cohorts of HSUs were created from the National Ambulatory Care Reporting System in 2015/2016 for children with the top 10% of ED presentations. Controls were random samples of non-HSU patients. Factors were explored in multivariable logistic regression models. There were 151,497 HSUs (51.7% girls, average age, 6.4 years) and 591,545 controls (53.1% girls; average age, 7.4 years). High-system ED users were more likely to be younger (adjusted odds ratio [aOR], 0.89 per 5 years; 95% confidence interval [CI], 0.88-0.89), live in less populated areas (aOR, 1.85; 95% CI, 1.82-1.88), and from lowest income neighborhoods (aOR, 1.51; 95% CI, 1.48-1.54) than controls. High-system ED users had higher proportions of presentations for pediatric complex chronic (aOR, 1.25 per 0.25 increase; 95% CI, 1.21-1.29), respiratory (aOR, 1.14 per 0.25; 95% CI, 1.12-1.15), and mental health (aOR, 1.14 per 0.25; 95% CI, 1.13-1.16) conditions than controls. Complex factors underlie pediatric health care utilization decisions. Findings identified conditions to target in interventions to improve health care access and utilization. Future work should engage children and families to design interventions.

Impact of the COVID-19 pandemic on emergency healthcare utilization: a cohort study

BackgroundEmergency department (ED) crowding is a burden on public health, so understanding the characteristics of frequent ED users is a key concern of the healthcare system and policy makers. This study aims to examine the characteristics and healthcare-seeking behaviors in frequent ED users before and during the COVID-19 pandemic.MethodsA retrospective observational study was conducted on ED users aged 18 years and over admitted to Taipei City Hospital in February 2019-January2020 (before pandemic) and February 2020-January2021 (during pandemic) (N = 120,011). Frequent and ED users were defined as patients with four or more ED visits in a year. Multivariate logistic regression was used to identify the predictors of frequent ED use before and during the COVID-19 pandemic.ResultsMonthly emergency department visits were significantly lower during the pandemic (by 10.1-26.8%). Frequent ED patients had shorter lengths of stay in the ED during the pandemic (212.5 vs.233.9 minutes; P < 0.0001). The proportion of ED patients receiving chest CT examination during the pandemic has increased by 0.5-0.6%. After adjusting for sociodemographic factors, triage status, mode of arrival, and copayment exemption, patients with a triage status of level 4-5 (AOR=1.60, 95% CI: 1.13-2.28), diagnosis of pneumonia (AOR=1.85, 95% CI: 1.07-3.17), giddiness (AOR=2.85, 95% CI: 1.82-4.45), dyspnea (AOR=1.85, 95% CI: 1.00-3.39), or chronic kidney disease (AOR=5.05, 95% CI: 2.66-9.59) were more likely to be frequent ED visitors during the pandemic.ConclusionsSince SAR-CoV-2 is highly contagious, it is imperative to educate non-emergent patients to utilize outpatient medical services rather than emergency medical services to reduce the risk of COVID-19 outbreaks at the ED.Key messages This study found that the utilization of emergent medical services during the COVID-19 pandemic significantly decreased by 10.1%–26.8% compared to before the COVID-19 pandemic.The lengths of stay in frequent ED users during the COVID-19 pandemic were significantly shorter than that in frequent ED users before the COVID-19 pandemic.

Association between mood disorders and frequent emergency department use: a cross-sectional study

ObjectivesFrequent emergency department (ED) use is a growing problem that is associated with poor patient outcomes and increased health care costs. Our objective was to analyze the association between mood disorders and the incidence of frequent ED use.MethodsWe used the Canadian Community Health Survey conducted by Statistics Canada, 2015–2016. Mood disorder was defined as depression, bipolar disorder, mania, or dysthymia. Frequent ED use was defined as 4 or more visits in the year preceding the interview. Multivariable log-binomial regression models were used to determine the associations between mood disorders and frequent ED use.ResultsAmong the 99,009 participants, 8.4% had mood disorders, 80.3% were younger than 65, and 2.2% were frequent ED users. Mood disorders were significantly associated with the 1-year cumulative incidence of frequent ED use (RR = 2.5, 95% CI 2.2–2.7), after adjusting for several potential confounders.ConclusionsThis national survey showed that people with a mood disorder had a three-fold risk of frequent ED use, compared to people without mood disorder. These results can inform the development of policies and targeted interventions aimed at identifying and supporting ED patients with mood disorder.

TU43. SCARS OF SOCIOECONOMIC STRESS: EPIGENETIC AGE

Emergency department (ED) visits have continued to rise, and frequent ED users account for up to 8% of all ED visits. Reducing visits by frequent ED users may be one way to help reduce health care costs. We hypothesize that frequent users have unique ED utilization patterns resulting in differences in health care charges.We conducted a retrospective review of electronic medical records from an urban community teaching hospital for the year 2012 comparing the top 108 frequent ED users (> 12 visits/year) to a randomly selected group of 108 nonfrequent users (< 4 visits/year). We compared demographic characteristics, distance lived from the hospital, medical and psychiatric history, substance abuse history, diagnostic testing, disposition, and amount charged to the patient for each visit. We compared data using χ2 for proportions and t test or Wilcoxon rank sum based on normality of the data.The top 108 frequent ED users accounted for 1922 visits (2.9%), whereas the 108 nonfrequent users accounted for 150 visits (0.2%), in 2012 (all ED visits n = 65,398). Frequent users were more often unemployed, have public insurance, have mental health conditions, use tobacco, have a greater number of allergies to medications, and live closer to the hospital (P < .01). Disposition and median charge per visit did not differ between frequent and nonfrequent users ($1220 vs $1280). The total charges of the frequent ED users’ visits were $10,465,216.07 versus $1,012,610.21 for nonfrequent users.Frequent users have unique medical and social characteristics; however, disposition and visit charges did not differ from nonfrequent users.

Does Case Management Provide Support for Staff Facing Frequent Users of Emergency Departments? A Comparative Mixed-Method Evaluation of ED Staff Perception

ObjectiveFrequent users of emergency departments (FUED) account for a disproportionate number of emergency department (ED) visits and contribute to a wide range of challenges for ED staff. While several research has documented that case management (CM) tailored to FUED leads to a reduction in ED visits and a better quality of life (QoL) among FUED, whether there is added value for ED staff remains to be explored. This study aimed to compare, among staff in two academic EDs in Switzerland (one with and one without CM), the FUED-related knowledge, perceptions of the extent of the FUED issue, FUED-related work challenges and FUEDs’ legitimacy to use ED.MethodMixed methods were employed. First, ED physicians and nurses (N = 253) of the two EDs completed an online survey assessing their knowledge and perceptions of FUEDs. Results between healthcare providers working in an ED with CM to those working in an ED without CM were compared using independent two-sided T-tests. Next, a sample of participants (n = 16) took part in a qualitative assessment via one-to-one interviews (n = 6) or focus groups (n = 10).ResultsBoth quantitative and qualitative results documented that the FUED-related knowledge, the extent FUED were perceived as an issue and perceived FUEDs’ legitimacy to use ED were not different between groups. The level of perceived FUED-related challenges was also similar between groups. Quantitative results showed that nurses with CM experienced more challenges related to FUED. Qualitative exploration revealed that lack of psychiatric staff within the emergency team and lack of communication between ED staff and CM team were some of the explanations behind these counterintuitive findings.ConclusionDespite promising results on FUEDs’ QoL and frequency of ED visits, these preliminary findings suggest that CM may provide limited support to ED staff in its current form. Given the high burden of FUED-related challenges encountered by ED staff, improved communication and FUED-related knowledge transfer between ED staff and the CM team should be prioritized to increase the value of a FUED CM intervention for ED staff.

Cross-sectional Analysis of Food Insecurity and Frequent Emergency Department Use.

IntroductionEmergency department (ED) patients have higher than average levels of food insecurity. We examined the association between multiple measures of food insecurity and frequent ED use in a random sample of ED patients.MethodsWe completed survey questionnaires with randomly sampled adult patients from an urban public hospital ED (n = 2,312). We assessed food insecurity using four questions from the United States Department of Agriculture Household Food Security Survey. The primary independent variable was any food insecurity, defined as an affirmative response to any of the four items. Frequent ED use was defined as self-report of ≥4 ED visits in the past year. We examined the relationship between patient food insecurity and frequent ED use using bivariate and multivariable analyses and examined possible mediation by anxiety/depression and overall health status.ResultsOne-third (30.9%) of study participants reported frequent ED use, and half (50.8%) reported any food insecurity. Prevalence of food insecurity was higher among frequent vs. non-frequent ED users, 62.8% vs 45.4% (P <0.001). After controlling for potential confounders, food insecurity remained significantly associated with frequent ED use (adjusted odds ratio 1.48, 95% confidence interval, 1.20–1.83). This observed association was partially attenuated when anxiety/depression and overall health status were added to models.ConclusionThe high observed prevalence of food insecurity suggests that efforts to improve care of ED patients should assess and address this need. Further research is needed to assess whether addressing food insecurity may play an important role in efforts to reduce frequent ED use for some patients.

Impact of the COVID-19 Pandemic on Healthcare-Seeking Behaviors among Frequent Emergency Department Users: A Cohort Study.

In 2020, Taiwan’s healthcare system faced a notable burden imposed by the coronavirus disease (COVID-19) pandemic. Emergency department (ED) is a high-risk area for severe acute respiratory syndrome coronavirus 2 transmission. The effect of COVID-19 on the utilization of ED services among frequent ED users remains unknown. This cohort study determined the impact of the COVID-19 pandemic on healthcare-seeking behaviors among frequent ED users at Taipei City Hospital, Taiwan. We included ED users aged ≥ 18 years admitted to Taipei City Hospital during February 2019–January 2020 (before the pandemic) and February 2020–January 2021 (during the pandemic). Frequent ED users were patients with four or more ED visits per year. Stepwise logistic regression was performed to identify predictors of frequent ED use during the COVID-19 pandemic. Frequent ED users had shorter hospital stays in the ED during the pandemic. After adjusting for sociodemographic factors and other covariates, patients with a triage status of level 4–5, pneumonia diagnosis, giddiness, or dyspnea were more likely frequent ED visitors during the COVID-19 pandemic. To reduce the risk of acquiring COVID-19, it is important to utilize territorial healthcare or telehealth to avoid inappropriate ED visits for patients with a low level of risk or chronic disease.

Race, health, and socioeconomic disparities associated with malingering in psychiatric patients at an urban emergency department

ObjectiveTo examine clinical and sociodemographic differences between psychiatric patients suspected of malingering and non-malingering controls in an urban emergency department (ED) setting. MethodsWe used retrospective chart review to compare 57 psychiatric patients suspected of malingering with 195 date-matched controls. We examined evidence used for malingering and documented secondary gains. ResultsThe prevalence of malingering was 5.6–7.1%, with documented evidence consistent with DSM-V guidelines. Malingering patients were more likely to be male (p < .001), > 45 years old (p = .002), Black (p = .049), unhoused (p < .001), and frequent users of ED (p < .001). Psychiatric diagnoses were found in ~75% of malingerers. Diagnosis of antisocial personality (OR = 8.03, p = .013) and substance use disorder (OR = 2.05, p = .018) predicted increased probability of malingering. Malingering encounters were more likely to result in discharges (p < .001). The most common secondary gains were unmet clinical needs. ConclusionsResults support adaptational models of malingering. Malingering patients are more likely to have sociodemographic vulnerabilities. A disproportionate number of malingering patients have unmet needs for psychiatric treatment and resources. The study provides further evidence for inequities that may be related to social and structural determinants of health.

Pediatric high users of Canadian hospitals and emergency departments.

IntroductionFew studies have examined the most frequent pediatric users of hospital services. Our objective was to determine the clinical diagnoses, demographic characteristics, and medical severity of high-use pediatric patients in Canada.MethodsWe conducted a retrospective analysis of patients <18 years of age who either were admitted to hospital or visited an emergency department (ED) using the Canadian Institute for Health Information’s (CIHI) Dynamic Cohort of Complex, High System Users. The analysis of hospital admission data excluded Quebec and Manitoba. ED data was only available for Alberta and Ontario.Results121 104 patients were identified as the most frequent hospital users and 459 998 patients as the most frequent ED users. High users were more likely to reside in a rural community, to be in a lower income quintile, and face more deprivation. The most frequent conditions for hospitalization for high use patients were disorders related to length of prematurity and fetal growth, respiratory and cardiovascular disorders specific to the perinatal period, and haemorrhagic and haematological disorders of fetus and newborn. For the most frequent ED users, the most common clinical diagnoses were acute upper respiratory infections, injuries to the head, and diseases of the middle ear and mastoid.ConclusionPediatric high users by frequency of hospital and ED services are a distinct population. Better understanding their characteristics will allow for more appropriate planning of children’s health services and help identify areas for effective preventive or quality improvement initiatives.

A Qualitative Study of Barriers and Facilitators to Transitions From the Emergency Department to Outpatient Mental Health Care.

People with psychiatric disorders are among the most frequent users of emergency departments (EDs). The transition of care from the ED to outpatient mental health treatment may be important for continuity of care; however, little is known about the barriers and facilitators that patients experience in transitions to and engagement in outpatient mental health care. In this qualitative study, the authors examined the perspectives of patients and providers on these barriers and facilitators at the patient, provider, and health care system levels. The authors (trained interviewers) conducted 30 semistructured interviews with patients and 15 interviews with 13 mental health providers. Data were analyzed by using thematic analysis. Patients and providers discussed similar barriers and facilitators to patient transitions and engagement in care. Patients with psychiatric disorders experienced barriers and facilitators at multiple levels when engaging in mental health care after discharge from the ED. Patient-level themes included openness to treatment and logistical challenges. Provider-level themes focused on the connection between patients and providers and on establishing and maintaining contact. Themes at the health care system level were coordination between the ED and outpatient clinics, managing appointments, and health care resources. Key factors that influence transitions of care from the ED to outpatient treatment include patients' complex health and life circumstances, the establishment of a relationship with providers built on trust and compassion, and the level of coordination between care settings.

Effectiveness of interventions to reduce adverse outcomes among older adults following emergency department discharge: Protocol for an overview of systematic reviews

Background: Older adults are frequent users of Emergency departments (ED) and this trend will continue due to population ageing and the associated increase in healthcare needs. Older adults are vulnerable to adverse outcomes following ED discharge. A number of heterogeneous interventions have been developed and implemented to improve clinical outcomes among this cohort. A growing number of systematic reviews have synthesised evidence regarding ED interventions using varying methodologies. This overview aims to synthesise the totality of evidence in order to evaluate the effectiveness of interventions to reduce adverse outcomes in older adults discharged from the ED. Methods: To identify relevant reviews, the following databases will be searched: Cochrane Database of Systematic reviews, Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports, Databases of Abstracts of Reviews of Effects, PubMed, MEDLINE, Epistemonikos, Ageline, Embase, PEDro, Scopus, CINAHL and the PROSPERO register. The search for grey literature will include Open Grey and Grey Literature Reports. Systematic reviews of randomised controlled trials will be analysed to assess the effect of ED interventions on clinical and process outcomes in older adults. Methodological quality of the reviews will be assessed using the Assessment of Multiple Systematic Reviews 2 tool. The review will be reported in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Summary of findings will include a hierarchical rank of interventions based on estimates of effects and the quality of evidence. Discussion: This overview is required given the number of systematic reviews published regarding the effectiveness of various ED interventions for older adults at risk of adverse outcomes following discharge from the ED. There is a need to examine the totality of evidence using rigorous analytic techniques to inform best care and potentially develop a hierarchy of treatment options.

Impact of emergency department length of stay on anxiety and comfort in older people

IntroductionOlder people are frequent emergency department (ED) users, a vulnerable population and often have long stays in the ED. The aim of this study was to determine whether ED length of stay (LOS) had an impact on older people’s (aged ≥65 years) anxiety, comfort and adverse events. MethodsThis prospective observational study was conducted in Melbourne, Australia. Patients (n = 301) from three EDs were classified by ED LOS: ≤4-hours (n = 89), 4–8 h (n = 136) and >8-hours (n = 76). Current state and trait anxiety and comfort were measured in ED. Adverse event data were collected from medical records. LOS groups were compared using Chi-Square and Kruskal-Wallis test. ResultsThere was no significant difference in Trait Anxiety Scores. Patients with ED LOS ≤ 4-hours had lower median State Anxiety Scores (p = 0.003), were less likely to require ward admission (p < 0.001), and more likely to require short stay unit admission (p < 0.001). There were no significant differences between groups in comfort or adverse events during ED care or hospitalisation (for admitted patients). ConclusionThe impact of ED LOS on the anxiety of older ED users appears limited. There was no association identified between ED LOS and comfort during ED care or adverse events during ED care or hospitalisation.

"I wanted to participate in my own care": Evaluation of a Patient Navigation Program.

IntroductionPatient navigation programs can help people overcome barriers to outpatient care. Patient experiences with these programs are not well understood. The goal of this study was to understand patient experiences and satisfaction with an emergency department (ED)-initiated patient navigation (ED-PN) intervention for US Medicaid-enrolled frequent ED users.MethodsWe conducted a mixed-methods evaluation of patient experiences and satisfaction with an ED-PN program for patients who visited the ED more than four times in the prior year. Participants were Medicaid-enrolled, English- or Spanish-speaking, New Haven-CT residents over the age of 18. Pre-post ED-PN intervention surveys and post-ED-PN individual interviews were conducted. We analyzed baseline and follow-up survey responses as proportions of total responses. Interviews were coded by multiple readers, and interview themes were identified by consensus.ResultsA total of 49 participants received ED-PN. Of those, 80% (39/49) completed the post-intervention survey. After receiving ED-PN, participants reported high satisfaction, fewer barriers to medical care, and increased confidence in their ability to coordinate and manage their medical care. Interviews were conducted until thematic saturation was reached. Four main themes emerged from 11 interviews: 1) PNs were perceived as effective navigators and advocates; 2) health-related social needs were frequent drivers of and barriers to healthcare; 3) primary care utilization depended on clinic accessibility and quality of relationships with providers and staff; and 4) the ED was viewed as providing convenient, comprehensive care for urgent needs.ConclusionsMedicaid-enrolled frequent ED users receiving ED-PN had high satisfaction and reported improved ability to manage their health conditions.

Identifying medication-related problems in pharmacist-run home visits

BackgroundHome visits (HVs) may be warranted for many reasons (e.g., uncontrolled disease states, suspected psychosocial issues, frequent hospitalizations, poor health literacy). Patients who frequently visit the emergency department (ED) are high-risk individuals, oftentimes exhibiting health-related barriers and medication-related problems (MRPs). ObjectivesThis study seeks to answer whether HVs for frequent ED users conducted by a pharmacist with pharmacy students will detect more MRPs compared to office visits (OVs) and enhance patient perception of HV services. MethodsPatients who visited the ED at least twice over a 12-month period were included in a retrospective chart review. Eligible patients were randomized into an HV group or OV group. Patients in the HV group were visited by a pharmacist and pharmacy students to identify and resolve MRPs, whereas patients in the OV arm brought their medications into the office for review. Patients in the HV group completed a pre- and postvisit survey about their experiences. ResultsEighteen patients participated in the study: 10 patients were randomized to the OV arm and 8 patients were randomized to the HV arm. A total of 39 MRPs were identified in 8 HVs versus 33 MRPs in 10 OVs (mean 5 ± 0.926 vs. 3.3 ± 1.89, P = 0.034). Overall, nonadherence was the most common MRP and medication reconciliation was the most common intervention. All 8 HV patients completed the pre- and post-HV surveys. Post-HV survey results indicated that patients agreed that student pharmacists were professional team members and that their HV was needed. The patients agreed to recommend a pharmacist-run HV. ConclusionPatient homes serve as alternative and convenient spaces for pharmacists to help manage their medications, specifically to identify MRPs and provide meaningful recommendations.
