Characteristics Of Emergency Department Visits Research Articles

Association between stringency of lockdown measures and emergency department visits during the COVID-19 pandemic: A Dutch multicentre study.

The COVID-19 outbreak disrupted regular health care, including the Emergency Department (ED), and resulted in insufficient ICU capacity. Lockdown measures were taken to prevent disease spread and hospital overcrowding. Little is known about the relationship of stringency of lockdown measures on ED utilization. This study aimed to compare the frequency and characteristics of ED visits during the COVID-19 outbreak in 2020 to 2019, and their relation to stringency of lockdown measures. A retrospective multicentre study among five Dutch hospitals was performed. The primary outcome was the absolute number of ED visits (year 2018 and 2019 compared to 2020). Secondary outcomes were age, sex, triage category, way of transportation, referral, disposition, and treating medical specialty. The relation between stringency of lockdown measures, measured with the Oxford Stringency Index (OSI) and number and characteristics of ED visits was analysed. The total number of ED visits in the five hospitals in 2019 was 165,894, whereas the total number of visits in 2020 was 135,762, which was a decrease of 18.2% (range per hospital: 10.5%-30.7%). The reduction in ED visits was greater during periods of high stringency lockdown measures, as indicated by OSI. The number of ED visits in the Netherlands has significantly dropped during the first year of the COVID-19 pandemic, with a clear association between decreasing ED visits and increasing lockdown measures. The OSI could be used as an indicator in the management of ED visits during a future pandemic.

Prevalence and Characteristics of Emergency Department Visits by Pregnant People: An Analysis of a National Emergency Department Sample (2010-2020).

The number and characteristics of pregnant patients presenting to the emergency department (ED) has not been well described. Our objective in this study was to determine the prevalence and characteristics of pregnant patients presenting to EDs in the US between 2010-2020. We completed a retrospective, cross-sectional study of patient encounters at hospital-based EDs in the US from 2010-2020. Using the ED subsample of the National Hospital Ambulatory Medical Care Survey (NHAMCS) we identified ED visits for female patients aged 15-44years. We defined a subsample of these as visits for pregnant patients using discharge diagnosis codes specific to pregnancy. We compared this population of pregnant patient visits to those for non-pregnant patients and computed point estimates for nationally weighted values. Multivariable linear regression was used to determine factors independently associated with pregnant patient visits. The 2010-2020 NHAMCS dataset included 255,963 ED visits. Of these visits 59,080 were for female patients 15-44years old, and 6,068 of those visits were for pregnant patients. Pregnant patients accounted for 3% (95% confidence interval [CI] 2.7-3.2) of all ED visits and 8.6% (95% CI 8-9.3) of all visits among female patients 15-44years. Weighting to a national sample, this equates to 2.77 million pregnant patients presenting for ED visits annually. Pregnant patients were more likely to be Black, Hispanic, or to use public insurance. Pregnant patients make up a significant number of ED visits annually and are more likely to be people of color or publicly insured. Interventions to address the effects of changing abortion legislation on emergency medicine practice may benefit from consideration that certain populations of pregnant people are more likely to present to the ED for care.

Hospital usage for oral and dental conditions in Hawaii: A cross-sectional study using the 2021 Hawaii statewide hospital data.

To investigate the frequency of emergency department (ED) usage primarily for oral/dental conditions in Hawaii and to examine social-demographic factors associated with the identified ED visits. This was a cross-sectional study of the 2021 Hawaii Statewide Hospital data. We identified records indicating ED usage and a primary diagnosis of non-traumatic dental conditions (NTDC) and other oral dental conditions (OODC). Descriptive analyses of ED visits for NTDC and OODC were performed to identify vulnerable individuals based on age, sex, race/ethnicity, primary source of payment, county of residence, and total charges per hospital record. A multivariable negative binomial regression model included age, sex, and county of residence was used to obtain adjusted rate ratios (aRR) and 95% confidence intervals (CI) of ED visits for NTDC. Among hospital records with diagnoses for oral or dental conditions (n = 12,336), 97% indicated ED, of which half had an NTDC diagnosis, and the remaining half had an OODC diagnosis. Distinct differences in the characteristics of ED visits were observed between NTDC and OODC. The median total charges per record indicating ED for NTDC and OODC were $1439 and $2439, respectively. A higher rate of ED visits for NTDC was found for those aged 21-44 (aRR [95%CI] = 3.02 [2.41, 3.80], reference: 0-9 years) and those living in a less populous county (Hawaii: 1.73 [1.43, 2.07]; Kauai: 1.78 [1.45, 2.19], reference: Honolulu). Continued effort to improve dental health is required to reduce ED visits for oral and dental conditions among Hawaii residents, especially for vulnerable individuals.

52 An Evaluation of Satisfaction with Emergency Department Care in Children and Adolescents with Mental Health Concerns

Abstract Background Increasingly, the emergency department (ED) is a vital safety net for children and adolescents with mental health concerns seeking crisis care. Evaluating patient and parent/caregiver experience and satisfaction with care is essential to improve the quality of mental health services provided. Objectives The primary objective was to evaluate total satisfaction with the delivery of ED mental health care in two paediatric EDs in Alberta, Canada (Stollery Children's Hospital and Alberta Children's Hospital). Secondary objectives included exploring aspects of ED mental health care (staff interpersonal skills, confidentiality/privacy, and patient-reported outcomes of care) associations with general satisfaction, patient and ED visit characteristic associations with total satisfaction score, and care experience themes. Design/Methods We enrolled patients <18 years of age presenting with a mental health concern—e.g., anxiety, disruptive behaviour, self-harm, depression, situational crisis—over a 12-month period (February 1, 2020—January 31, 2021). Satisfaction data were collected using the Service Satisfaction Scale, which includes quantitative and qualitative data on aspects of ED mental health care. ED visit (length of stay, mental health and psychiatry consultations, hospital admission) and patient (discharge diagnoses, age, sex) data were collected. We evaluated associations of general satisfaction with ED mental health care using Pearson’s correlation coefficient tests, and associations between total satisfaction score with patient and ED visit characteristics using multivariable regression analyses. Inductive thematic analysis of qualitative feedback identified satisfaction and patient experience themes. Results 646 participants were enrolled with most being Caucasian (71.2%; 460/646) and female (56.3%; 364/646); the median age was 13 years (IQR, 11-15 years). The most common discharge diagnosis was anxiety or stress-related disorders (39.5%; 245/620). Parents/caregivers and adolescents were most satisfied with confidentiality and respect in the ED and least satisfied with how the ED services helped reduce symptoms and/or problems. Greater satisfaction was reported for parents/caregivers whose child received care at Alberta Children’s Hospital (p=0.003). General satisfaction was strongly associated with the perceived amount of help received in the ED (r=0.85). ED visit characteristics associated with total satisfaction score included an evaluation by a mental health team member (p=0.004) and psychiatrist consultation (p=0.05). Written comments demonstrated satisfaction with ED provider attitudes and interpersonal skills and dissatisfaction with access to mental health and addictions care, wait time, and COVID-19. Conclusion The results reflect the need to improve the satisfaction with ED mental health care delivery, with a particular focus on enhancing access to care by appropriate mental health providers.

This cross-sectional study examines emergency department use among older adults with Alzheimer disease and related dementias.

Trends and characteristics of potentially preventable emergency department visits among patients with cancer in the US.

e13643 Background: An initial step to reducing emergency department (ED) visits among patients with cancer is to identify the characteristics of patients visiting the ED and examine which of those visits could be prevented. The objective of this study was to explore nationwide trends and characteristics of ED visits and examine factors associated with potentially preventable ED visits and unplanned hospitalizations among patients with cancer in the US. Methods: This cross-sectional study used data on ED visits from the National Hospital Ambulatory Medical Care Survey from January 1, 2012, to December 31, 2019; US Cancer Statistics reports were used to estimate new cancer cases each year. Frequencies and trends of ED visits by adult patients (aged ≥18 years) with cancer were calculated. The primary outcome was potentially preventable ED visits (using the Centers for Medicare & Medicaid Services definition), and secondary outcomes were hospitalizations and the immediacy of the ED visits. Multivariable logistic regression analyses were performed to examine the associations of patient, hospital, and temporal factors with potentially preventable ED use and ED use resulting in hospitalization. Results: Among 854911106 ED visits, 35510014 (4.2%) were made by patients with cancer (mean [SD] age, 66.2 [16.2] years); of those, 55.2% of visits were among women, 73.2% were among non-Hispanic White individuals, 89.8% were among patients living in a private residence, and 54.3% were among Medicare enrollees. A total of 18 316 373 ED visits (51.6%) were identified as potentially preventable, and 5 770 571 visits (21.3%) were classified as high acuity. From 2012 to 2019, potentially preventable ED visits increased from 1 851 692 to 3 214 276. Pain (36.9%) was the most common reason for potentially preventable ED visits. The number of patients who visited an ED because of pain increased from 1 192 197 in 2012 to 2 405 849 in 2019 (a 101.8% increase). Overall, 28.9% of ED visits resulted in unplanned hospitalizations, which did not change significantly over time (from 32.2% in 2012 to 26.6% in 2019; P = .78 for trend). Factors such as residence in a nursing home (odds ratio, 1.73; 95% CI, 1.25-2.41) were positively associated with having a potentially preventable ED visit, and factors such as the presence of more than 1 comorbidity (odds ratio, 1.82; 95% CI, 1.43-2.32) were positively associated with having an unplanned hospitalization. Conclusions: In this study, 51.6% of ED visits among patients with cancer were identified as potentially preventable, and the absolute number of potentially preventable ED visits increased substantially between 2012 and 2019. These findings highlight the need for cancer care programs to implement evidence-based interventions to better manage cancer treatment complications, such as uncontrolled pain, in outpatient and ambulatory settings.

Frequencies and reasons for unplanned emergency department return visits by older adults: a cohort study

BackgroundAs unplanned Emergency Department (ED) return visits (URVs) are associated with adverse health outcomes in older adults, many EDs have initiated post-discharge interventions to reduce URVs. Unfortunately, most interventions fail to reduce URVs, including telephone follow-up after ED discharge, investigated in a recent trial. To understand why these interventions were not effective, we analyzed patient and ED visit characteristics and reasons for URVs within 30 days for patients aged ≥ 70 years.MethodsData was used from a randomized controlled trial, investigating whether telephone follow-up after ED discharge reduced URVs compared to a satisfaction survey call. Only observational data from control group patients were used. Patient and index ED visit characteristics were compared between patients with and without URVs. Two independent researchers determined the reasons for URVs and categorized them into: patient-related, illness-related, new complaints and other reasons. Associations were examined between the number of URVs per patient and the categories of reasons for URVs.ResultsOf the 1659 patients, 222 (13.4%) had at least one URV within 30 days. Male sex, ED visit in the 30 days before the index ED visit, triage category “urgent”, longer length of ED stay, urinary tract problems, and dyspnea were associated with URVs. Of the 222 patients with an URV, 31 (14%) returned for patient-related reasons, 95 (43%) for illness-related reasons, 76 (34%) for a new complaint and 20 (9%) for other reasons. URVs of patients who returned ≥ 3 times were mostly illness-related (72%).ConclusionAs the majority of patients had an URV for illness-related reasons or new complaints, these data fuel the discussion as to whether URVs can or should be prevented.Trial registrationFor this cohort study, we used data from a randomized controlled trial (RCT). This trial was pre-registered in the Netherlands Trial Register with number NTR6815 on the 7th of November 2017.

Emergency Department Visits During Pregnancy.

Pregnant women often seek care in an emergency department (ED). We sought to describe the frequency, characteristics, and factors associated with increased ED visits during pregnancy. We conducted a retrospective cohort study using administrative health data of all pregnancies resulting in a live birth at 20 or more weeks of gestation in Alberta, Canada, from 2011 to 2017. The primary outcome was the occurrence of any ED visit during pregnancy. The secondary outcomes were ED visit characteristics and discharge disposition. We calculated rate ratios (RRs) and 95% confidence intervals (CIs) for associations between sociodemographic and clinical factors and increased ED visits during pregnancy using random-effect negative binomial regression adjusting for multiple pregnancies per person during the study period. We included 255,929 pregnancies from 193,965 women. Of all the pregnancy episodes followed, 37.3% (95% CI 37.1 to 37.5) had at least 1 ED visit, resulting in a total of 226,811 ED visits and an overall ED visit rate of 94.0 visits per 100 pregnancies (95% CI 93.6 to 94.3). Most visits were nonobstetric (46.4%) and resulted in ED discharge (85.3%). Increased ED visits were associated with living in remote (RR 6.9; 95 %CI 6.7 to 7.1) or rural (RR 3.4; 95% CI 3.4 to 3.5) areas, younger age (RR 1.9; 95% CI 1.8 to 2.0), intensive prenatal care (RR 1.5; 95% CI 1.5 to 1.5), major/moderate health conditions (RR 1.6; 95% CI 1.6 to 1.6), mental health conditions (RR 1.6; 95% CI 1.5 to 1.6), and high antepartum risk score (RR 1.1; 95% CI 1.1 to 1.1). Approximately 1 in 3 women in our sample visited the ED during pregnancy. A higher number of visits occurred in those with rural/remote residence, younger maternal age, and concomitant health conditions.

Trends and Characteristics of Potentially Preventable Emergency Department Visits Among Patients With Cancer in the US

An initial step to reducing emergency department (ED) visits among patients with cancer is to identify the characteristics of patients visiting the ED and examine which of those visits could be prevented. To explore nationwide trends and characteristics of ED visits and examine factors associated with potentially preventable ED visits and unplanned hospitalizations among patients with cancer in the US. This cross-sectional study used data on ED visits from the National Hospital Ambulatory Medical Care Survey from January 1, 2012, to December 31, 2019; US Cancer Statistics reports were used to estimate new cancer cases each year. Frequencies and trends among 35 510 014 ED visits by adult patients (aged ≥18 years) with cancer were calculated. The primary outcome was potentially preventable ED visits, and secondary outcomes were unplanned hospitalizations and the immediacy of the ED visits. Potentially preventable ED visits were identified using the Centers for Medicare & Medicaid Services definition. The Emergency Severity Index, a triage algorithm that ranks patients based on the urgency of their health care condition, was used to measure the immediacy of ED visits (immediate [most urgent], emergent, urgent, less urgent, and nonurgent), with the categories of immediate and emergent classified as high acuity. The Wilcoxon rank sum test was used to calculate trends in ED visits among patients with cancer over time. Multivariable logistic regression analyses were performed to examine the associations of patient, hospital, and temporal factors with potentially preventable ED use and ED use resulting in hospitalization. Among 854 911 106 ED visits, 35 510 014 (4.2%) were made by patients with cancer (mean [SD] age, 66.2 [16.2] years); of those, 55.2% of visits were among women, 73.2% were among non-Hispanic White individuals, 89.8% were among patients living in a private residence, and 54.3% were among Medicare enrollees. A total of 18 316 373 ED visits (51.6%) were identified as potentially preventable, and 5 770 571 visits (21.3%) were classified as high acuity. From 2012 to 2019, potentially preventable ED visits increased from 1 851 692 to 3 214 276. Pain (36.9%) was the most common reason for potentially preventable ED visits. The number of patients who visited an ED because of pain increased from 1 192 197 in 2012 to 2 405 849 in 2019 (a 101.8% increase). Overall, 28.9% of ED visits resulted in unplanned hospitalizations, which did not change significantly over time (from 32.2% in 2012 to 26.6% in 2019; P = .78 for trend). Factors such as residence in a nursing home (odds ratio, 1.73; 95% CI, 1.25-2.41) were positively associated with having a potentially preventable ED visit, and factors such as the presence of more than 1 comorbidity (odds ratio, 1.82; 95% CI, 1.43-2.32) were positively associated with having an unplanned hospitalization. In this study, 51.6% of ED visits among patients with cancer were identified as potentially preventable, and the absolute number of potentially preventable ED visits increased substantially between 2012 and 2019. These findings highlight the need for cancer care programs to implement evidence-based interventions to better manage cancer treatment complications, such as uncontrolled pain, in outpatient and ambulatory settings.

Impact of COVID-19 on the associated complications of high-risk conditions in a statewide pediatric emergency network.

The COVID-19 pandemic affected the volume and epidemiology of pediatric emergency department (ED) visits. We aimed to determine the rate of associated complications for 16 high-risk conditions in a Michigan statewide network of academic and community EDs during the pandemic. We conducted a cross-sectional study of pediatric ED visits among a network of 5 Michigan health systems during the pre-pandemic (March 1, 2019-March 10, 2020) and pandemic (March 11, 2020-March 31, 2021) periods. Data were collected from the medical record and included patient demographics, ED visit characteristics, procedure codes, and final International Classification of Diseases, 10th Revision, Clinical Modification diagnosis codes. Selection of codes for 16 high-risk conditions and diagnostic complications were identified using previously described methods. Characteristics of ED visits were compared before versus during the pandemic using χ2 and Fisher's exact tests. We used multilevel logistic regression to analyze covariates and potential confounders for being diagnosed with a high-risk condition or a complication of a high-risk condition. A total of 417,038 pediatric ED visits were analyzed. The proportion of patients presenting with 10 of 16 high-risk conditions (including appendicitis, sepsis, and stroke) was higher in the pandemic period compared with pre-pandemic (P < 0.01). Despite this, there was no significant increase in the frequency of complications for any of the 16 high-risk conditions during the pandemic. The adjusted odds of being diagnosed with appendicitis (pre-pandemic 0.23% vs pandemic 0.52%; odds ratio [OR], 1.19 [95% confidence interval, CI, 1.00-1.41]), diabetic ketoacidosis (pre-pandemic 0.16% vs pandemic 0.52%; OR, 2.40 [95% CI, 2.07-2.78]), intussusception (pre-pandemic 0.05% vs pandemic 0.07%; OR, 1.64 [95% CI, 1.22-2.21)], and testicular torsion (pre-pandemic 0.10% vs pandemic 0.14%; OR, 1.64 [95% CI, 1.18-2.28]) was higher during the pandemic. Despite a higher proportion of ED visits attributed to high-risk conditions, there was no increase in complications, suggesting minimal impact of the pandemic on outcomes of pediatric ED visits.

Emergency Department Experience and the Use of Non-Pharmacologic Treatment for Acute Pain Among Patients with Sickle Disease

Background: Appropriate management for patients presenting to the Emergency Department (ED) with acute pain from vaso-occlusive episodes (VOE) primarily includes treatment with parenteral opioid and non-opioid analgesia and fluids if the episode is uncomplicated. Non-pharmacological strategies that significantly affect non-physical aspects of behavioral, social, and cultural life, have been studied for pain treatment in sickle cell patients; however, the data on the effectiveness of these methods are limited. Objectives: This work aims to assess the overall ED experience among patients seeking care for acute VOE. We also aim to assess any effective alternative pain management strategies used by patients to treat their acute pain symptoms. Methods: We conducted ED follow up assessments for patients who sought care in the ED for acute pain from vaso-occlusive episodes from January 1, 2022- July 15, 2022. These were brief individual phone interviews. The semi-structured interview guide was created using a hospital specific patient experience questionnaire in addition to questions pertaining to pain management in the acute and day-to-day settings, demographic data including, age, sex, emergency department visit characteristics (length of stay (LOS), emergency severity index assignment (ESI), time to first opioid). The interviews were analyzed using a framework matrix analysis. This qualitative data reduction technique was used to review, summarize, and classify the interview data. NVivo 20 qualitative data analysis software includes a framework matrix tool used to manage data and facilitate this analysis in which participant comments about key content were aggregated and entered for review. Results: Overview: Among the 21 patients who met study criteria, eight participants are included in this analysis. Six participants identified as male, and two participants identified as female. ED Experience: Patients rated their ED care from a 3/10 to a 10/10 (avg 6.4, +/- 2.6). Common themes included prolonged wait times for pain management (6/8 participants). Five of the eight patients interviewed expressed gratitude for the care provided though noted some room for improvement. One participant noted "they could have been nicer to me. It's like they don't talk to each other" (2/8 participants). Patients also expressed frustration when intravenous access issues arise and compounding delays in treatment. Pain management: Three of the eight patients interviewed reported using scheduled opioids (oxycodone-5 patients, and methadone-2 patients) at home every 3-8 hours. One patient declined to answer questions about home opioid use. All patients received hydromorphone for acute management in the ED. Two of the eight patients expressed knowledge of their care coordination pain management plan. Alternative pain management: Five of the eight patients used heat or hot packs as their primary alternative pain management and specifically referenced this as an intervention that they would find helpful in the ED. Two patients prioritized distractions such as video games or other screen time. One patient relied on family support, massages, and meditation. Conclusions: Patients experiencing acute pain from VOE rely on the ED for care. Optimizing that care will not only improve patient's health, but also their well-being. Considering complementary alternatives for acute pain management including heat therapy (packs, blankets) as well as massage (heated chair) or distractions (video games, reading or movies) may provide additional benefits while patients seek care for acute pain crises.

Racial Differences in Emergency Department Visit Characteristics and Management of Preadolescents at Risk of Suicide.

Suicide rates and frequency of pediatric emergency department (ED) visits for suicidal thoughts and behaviors have increased among Black preadolescents in the United States in recent years. This study examined whether characteristics of ED visits and treatment management of preadolescents with suicidal thoughts and behaviors differed by race. An electronic medical record query identified patients ages 8-12 (N=504) who visited a pediatric ED with a psychiatric-related chief complaint in 2019. The authors examined suicidal thoughts and behaviors that were reported with the Ask Suicide-Screening Questions tool, ED clinical impression, and ED disposition overall and by race. Compared with other racial groups, Black preadolescents were less likely to report suicidal thoughts, despite equivalent lifetime histories of suicide attempts, and were more likely to be brought to the ED by police and discharged (instead of being admitted to inpatient psychiatric care). Research to better understand racial disparities in suicide risk among preadolescents can inform prevention efforts.

Emergency department visits and hospital admissions in kidney transplant recipients during the COVID-19 pandemic: A hospital-based study.

BACKGROUNDSeveral studies have demonstrated that the coronavirus disease 2019 (COVID-19) has affected daily living and the healthcare system. No previous study has described the consequences of COVID-19 on emergency department (ED) visits and hospital admission among kidney transplant (KT) recipients.AIMTo investigate the impact of the COVID-19 pandemic on ED visits and hospital admissions within 1 year in patients who underwent KT in Thailand.METHODSWe conducted a retrospective study at a university hospital in Thailand. We reviewed the hospital records of KT patients who visited the ED during the outbreak of COVID-19 (from January 2020 to December 2021). We used the previous 2 years as the control period in the analysis. We obtained baseline demographics and ED visit characteristics for each KT patient. The outcomes of interest were ED visits and ED visits leading to hospital admission within the 1st year following a KT. The rate of ED visits and ED visits leading to hospital admissions between the two periods were compared using the stratified Cox proportional hazards model.RESULTSA total of 263 patients were included in this study: 112 during the COVID-19 period and 151 during the control period. There were 34 and 41 ED visits after KT in the COVID-19 and control periods, respectively. The rate of first ED visit at 1 year was not significantly different in the COVID-19 period, compared with the control period [hazard ratio (HR) = 1.02, 95% confidence interval (CI): 0.54-1.92; P = 0.96]. The hospital admission rate was similar between periods (HR = 0.92, 95%CI: 0.50-1.69; P = 0.78).CONCLUSIONED visits and hospital admissions within the 1st year in KT recipients were not affected by the COVID-19 pandemic. Despite these findings, we believe that communication between post-KT patients and healthcare providers is essential to highlight the importance of prompt ED visits for acute health conditions, particularly in post-KT patients.

Mental Health Emergency Department Visits by Children Before and During the COVID-19 Pandemic.

ObjectivesTo describe pediatric mental health emergency department (ED) visit rates and visit characteristics before and during the COVID-19 pandemic.MethodsWe conducted a cross-sectional study of ED visits by children 5–17 years old with a primary mental health diagnosis from March 2018 to February 2021 at a 10-hospital health system and a children's hospital in the Chicago area. We compared demographic and clinical characteristics of children with mental health ED visits before and during the pandemic. We conducted an interrupted time series analysis to determine changes in visit rates.ResultsWe identified 8,127 pediatric mental health ED visits (58.5% female, 54.3% White, Not Hispanic/Latino and 42.4% age 13–15). During the pandemic, visits for suicide or self-injury increased 6.69% (95% CI 4.73, 8.65), and visits for disruptive, impulse control, conduct disorders increased 1.94% (95% CI 0.85, 3.03). Mental health ED visits by children with existing mental health diagnoses increased 2.29% (95% CI 0.34, 4.25). Mental health ED visits that resulted in medical admission increased 4.32% (95% CI 3.11, 5.53). The proportion of mental health ED visits at community hospitals increased by 5.49% (95% CI 3.31, 7.67). Mental health ED visit rates increased at the onset of the pandemic (adjusted incidence rate ratio [aIRR] 1.27, 95% CI 1.06, 1.50), followed by a monthly increase thereafter (aIRR 1.04, 95% CI 1.02, 1.06).ConclusionMental health ED visit rates by children increased during the COVID-19 pandemic. Changes in mental health ED visit characteristics during the pandemic may inform interventions to improve children's mental health.

Improving care coordination and reducing ED utilization through patient navigation.

Our study examines the impact of an emergency department (ED) patient navigation program for patients in a Medicaid accountable care organization across 3 hospitals in a large health system. Our program engages community health workers to (1) promote primary care engagement, (2) facilitate care coordination, and (3) identify and address patients' health-related social needs. Our study was a retrospective analysis of health care utilization and costs in the 30 days following the index ED visit, comparing individuals receiving ED navigation and matched controls. The primary outcome of interest was all-cause return ED visits, and our secondary outcomes were hospital admissions and completed primary care appointments. Patients with ED visits who received navigation were matched to comparable patients with ED visits without an ED navigator interaction. Outcomes were analyzed using fixed effects logistic regression models adjusted for patient demographics, ED visit characteristics, and preceding utilization. Our primary outcome was odds of a return ED visit within 30 days, and our secondary outcomes were odds of a hospitalization within 30 days and odds of having primary care visit within 30 days. In our sample, there were 1117 ED visits by patients meeting our inclusion criteria with an ED navigator interaction, with 3351 matched controls. ED navigation was associated with 52% greater odds of a completed follow-up primary care appointment (odds ratio [OR], 1.52; 95% CI, 1.29-1.77). In patients with no ED visits in the preceding 6 months, ED navigation was associated with 32% decreased odds of repeat ED visits in the subsequent 30 days (OR, 0.68; 95% CI, 0.52-0.90). There was no statistically significant impact on return ED visits in those with higher baseline ED utilization. Our program demonstrates that high-intensity, short-term patient navigation in the ED can help reduce ED visits in those with low baseline ED utilization and facilitate stronger connections with primary care.

The Characteristics of Syncope-Related Emergency Department Visits: Resource Utilization and Admission Rate Patterns in Emergency Departments.

Background and objectiveDecision-making about syncope patients presenting to the emergency department (ED) is challenging since physicians must balance the minimal risks of life-threatening conditions with the unessential use of expensive imaging or unnecessary hospitalizations. This study aimed to determine the characteristics of ED visits, resource utilization, and admission rate patterns related to syncope in the United States (US) during the period 2005-2015.MethodsData from the National Hospital Ambulatory Medical Care Survey (NHAMCS) on ED visits during the 11-year period from 2005 to 2015 were retrieved. ED visits for syncope were identified and compared against non-syncope ED visits. The demographic and clinical characteristics of patients, as well data on resource allocation and admission trends were captured and described for the syncope and the non-syncope groups.ResultsSyncope accounted for 1.11% of the total ED visits during the study period from 2005 to 2015. The incidence of syncope-related ED visits was higher among elderly females, whites, and non-Hispanics. The trend of admission rates showed a decline from about 30% in 2005-2010 to less than 20% in 2014 and 2015. Advanced imaging (CT or MRI) was ordered for 34% of syncope patients.ConclusionThe percentage of syncope-related ED visits remained stable during the study period, but the admission rates declined while the use of advanced imaging in syncope-related ED visits remained substantially high despite the advances in research and availability of clinical guidelines. Future research is needed to rationalize healthcare utilization in syncope-related ED visits and precisely identify the high-risk population.

Abstract 13179: Rates and Reasons for Emergency Department Use Among US Adults With Congenital Heart Disease

Introduction: The adult congenital heart disease (ACHD) population is growing and highly comorbid, requiring increasing emergency department (ED) use. Data on the rates and characteristics of ED visits can inform appropriate care pathways for ACHD patients. Methods: We performed a retrospective study of 16,946 commercially insured beneficiaries with ACHD in the 2016 IBM MarketScan database. Main outcome measures were rates and types of ED visits. Exposures included age, gender, primary beneficiary status, employment status, ACHD severity, cardiovascular (CV) and non-CV comorbidities. Results: Mean age was 35.2±14.2 years, 48.8% were female, and 30.5% had severe CHD. 21.1% had at least one ED visit (23.0% for severe vs. 20.3% for non-severe CHD, p&lt;0.001) while 8.1% had &gt;1 ED visit. Patients with ED visits were more likely to be ≥40 years old (41.0% vs 39.1%, p=0.035), female (53.4% vs 47.6%, p&lt;0.001), have severe CHD (33.2% vs 30.0%, p&lt;0.001), CV (33.0% vs 21.8%, p&lt;0.001) and non-CV comorbidities (38.2% vs 23.6%, p&lt;0.001), and less likely to be the primary beneficiary (56.6% vs 51.4%, p&lt;0.001) or employed (29.0% vs 25.6%, p&lt;0.001). The top five conditions for ED visits for all ACHD patients were CV (33.9%), followed by symptoms, signs, and ill-defined (25.4%), injury and poisoning (25%), respiratory (20.8%), and nervous system issues (14.5%). Compared to adults with non-severe ACHD, severe ACHD patients had more ED visits for CV (36.5% vs. 32.6%, p=0.023) and respiratory conditions (24.0 vs. 19.2%, p=0.001). Variables independently associated with ED visits are listed in the table. Conclusions: One in five ACHD patients had an ED visit, with cardiac and respiratory conditions being more common among adults with severe than non-severe ACHD. Our findings about the factors associated with ED visits provides information about potential interventions and care pathways that might help reduce the burden of ED visits in this high-risk population.

The effect of COVID-19 on the characteristics of adult emergency department visits: A retrospective cohort tertiary hospital experience in Riyadh

BackgroundOn March 2, 2020, Saudi Arabia identified the first positive COVID-19 case. Since then, several aspects of the COVID-19 impact on Emergency Departments (EDs) use have been reported. The objective of this study is to describe the pattern and characteristics of Emergency Department visits during the COVID-19 pandemic period, compared with the same period in the previous year, including the patients’ demographic information, acuity level, length of stay, and admission rate. MethodsData were collected from King Abdulaziz Medical City in Riyadh, Saudi Arabia. The health records of all the patients who presented at the Emergency Department from January 2019 to September 2020 were retrospectively reviewed. The variations in the patient and the visit characteristics were described for the periods before and during COVID-19. ResultsThe records of 209,954 patients who presented at the Emergency Department were retrieved. In contrast to 2019, the number of visits during the pandemic period reduced by 23%. A dramatic decrease was observed after the announcement of the first COVID-19 diagnosed case in Saudi Arabia, and subsequently the numbers gradually increased. The patients who presented at the Emergency Department during the pandemic period were slightly older (mean age, 43.1 versus 44.0 years), more likely to be older, more urgent and had a higher admission rate compared to the pre-pandemic period. There was a slight increase in visits during the daytime curfew hours and a decrease during the nighttime. ConclusionWe report a considerable decrease in the number of Emergency Department visits. The reduction was higher in non-urgent and less urgent cases. Patients presenting at the Emergency Department during the curfew times were more likely to stay longer in the Emergency Department and more likely to be admitted, compared with the pre-pandemic period.

28EMF The Opioid Epidemic Meets the Coronavirus Pandemic: Rates and Patient Characteristics of Emergency Department Visits for Opiate Use Disorder During the COVID-19 Pandemic in the Los Angeles County Public Hospital System

The COVID-19 pandemic led to profound challenges for health systems and disruptions in care for society’s most vulnerable patients, in particular people with opiate use disorders (OUD). The closure of outpatient addiction clinics, cessation of harm-reduction services, and lack of access to support groups have all been attributed to worsening outcomes for patients with OUD during the COVID-19 pandemic. Most concerningly, emerging evidence points to accelerated rates of overdose deaths. In Los Angeles, a city disproportionately affected by high rates of COVID-19, chronic housing insecurity, and substance use disorder, the Department of Public Health reported a 48% increase in accidental drug overdose deaths during the first five months of the pandemic.

Characteristics of Emergency Department Visits by Homeless Young Adults in the U.S.

PurposeHomeless young adults often seek health care at emergency departments (EDs) after they are no longer able to ignore a pressing health problem. However, a dearth of literature examines homeless young adults' ED visits. This study aimed to increase understanding of ED visits among homeless young adults within the U.S. MethodsData for this study were obtained from the 2011–2015 National Hospital Ambulatory Medical Care Survey. The sample for this study included all ED visits made by homeless and housed young adults aged 18–29 years (unweighted N = 25,068). ResultsED visits by homeless young adults were distinguished in terms of gender, region, payment sources, and triage level. Furthermore, ED visits made by homeless young adults were more likely related to mental health and suicide. Homeless young adults' ED visits were characterized by a longer average length of stay and were less likely to be referred to a physician or clinic for follow-up, given medication, or have a procedure performed in the ED. ConclusionsThis study highlighted differences in ED utilization for homeless young adults. The findings of this study suggest a need to further examine the characteristics of ED services received by homeless young adults to better understand differences in ED service receipt related to housing status. This knowledge can inform efforts to reduce costs through improving access to housing and outpatient mental health care and reducing stigma among health care professionals to ensure continuity of care.
