Research Priorities for Pediatric Emergency Care to Address Disparities by Race, Ethnicity, and Language.

Importance: Health care disparities are well-documented among children based on race, ethnicity, and language for care. An agenda that outlines research priorities for disparities in pediatric emergency care (PEC) is lacking. Objective: To investigate research priorities for disparities in PEC among medical personnel, researchers, and health care-affiliated community organizations. Design, Setting, and Participants: In this survey study, a modified Delphi approach was used to investigate research priorities for disparities in PEC. An initial list of research priorities was developed by a group of experienced PEC investigators in 2021. Partners iteratively assessed the list through 2 rounds of electronic surveys using Likert-type responses in late 2021 and early 2022. Priorities were defined as achieving consensus if they received a score of highest priority or priority by at least 60% of respondents. Asynchronous engagement of participants via online web-conferencing platforms and email correspondence with electronic survey administration was used. Partners were individuals and groups involved in PEC. Participants represented interest groups, research and medical personnel organizations, health care partners, and laypersons with roles in community and family hospital advisory councils. Participants were largely from the US, with input from international PEC research networks. Outcome: Consensus agenda of research priorities to identify and address health care disparities in PEC. Results: PEC investigators generated an initial list of 27 potential priorities. Surveys were completed by 38 of 47 partners (80.6%) and 30 of 38 partners (81.1%) in rounds 1 and 2, respectively. Among 30 respondents who completed both rounds, there were 7 family or community partners and 23 medical or research partners, including 4 international PEC research networks. A total of 12 research priorities achieved the predetermined consensus threshold: (1) systematic efforts to reduce disparities; (2) race, ethnicity, and language data collection and reporting; (3) recognizing and mitigating clinician implicit bias; (4) mental health disparities; (5) social determinants of health; (6) language and literacy; (7) acute pain-management disparities; (8) quality of care equity metrics; (9) shared decision-making; (10) patient experience; (11) triage and acuity score assignment; and (12) inclusive research participation. Conclusions and Relevance: These results suggest a research priority agenda that may be used as a guide for investigators, research networks, organizations, and funding agencies to engage in and support high-priority disparities research topics in PEC.

Opportunities for Diagnostic Improvement Among Pediatric Hospital Readmissions.

OBJECTIVES: Diagnostic errors, termed "missed opportunities for improving diagnosis" (MOIDs), are known sources of harm in children but have not been well characterized in pediatric hospital medicine. Our objectives were to systematically identify and describe MOIDs among general pediatric patients who experienced hospital readmission, outline improvement opportunities, and explore factors associated with increased risk of MOID. PATIENTS AND METHODS: Our retrospective cohort study included unplanned readmissions within 15 days of discharge from a freestanding children's hospital (October 2018-September 2020). Health records from index admissions and readmissions were independently reviewed and discussed by practicing inpatient physicians to identify MOIDs using an established instrument, SaferDx. MOIDs were evaluated using a diagnostic-specific tool to identify improvement opportunities within the diagnostic process. RESULTS: MOIDs were identified in 22 (6.3%) of 348 readmissions. Opportunities for improvement included: delay in considering the correct diagnosis (n = 11, 50%) and failure to order needed test(s) (n = 10, 45%). Patients with MOIDs were older (median age: 3.8 [interquartile range 1.5-11.2] vs 1.0 [0.3-4.9] years) than patients without MOIDs but similar in sex, primary language, race, ethnicity, and insurance type. We did not identify conditions associated with higher risk of MOID. Lower respiratory tract infections accounted for 26% of admission diagnoses but only 1 (4.5%) case of MOID. CONCLUSIONS: Standardized review of pediatric readmissions identified MOIDs and opportunities for improvement within the diagnostic process, particularly in clinician decision-making. We identified conditions with low incidence of MOID. Further work is needed to better understand pediatric populations at highest risk for MOID.

Resident Communication With Patients and Families Preferring Languages Other Than English.

OBJECTIVES: Patients and families preferring languages other than English (LOE) often experience inequitable communication with their health care providers, including the underutilization of professional interpretation. This study had 2 aims: to characterize resident-perceived communication with families preferring LOE and to evaluate the impact of language preference on frequency of resident interactions with hospitalized patients and families. METHODS: This was a cross-sectional study at a quaternary care children's hospital. We developed a questionnaire for residents regarding their interactions with patients preferring LOE. We concurrently developed a communication tracking tool to measure the frequency of resident communication events with hospitalized patients. Data were analyzed with logistic and Poisson regression models. RESULTS: Questionnaire results demonstrated a high level of resident comfort with interpretation, though more than 30% of residents reported "sometimes" or "usually" communicating with families preferring LOE without appropriate interpretation (response rate, 47%). The communication tracking tool was completed by 36 unique residents regarding 151 patients, with a 95% completion rate. Results demonstrated that patients and families preferring LOE were less likely to be present on rounds compared with their counterparts preferring English (adjusted odds ratio, 0.17; 95% confidence interval [CI], 0.07-0.39). Similarly, patients and families preferring LOE were less likely to receive a resident update after rounds (adjusted odds ratio, 0.29; 95% CI, 0.13-0.62) and received fewer resident updates overall (incidence rate ratio, 0.45; 95% CI, 0.30-0.69). CONCLUSIONS: Hospitalized patients and families preferring LOE experience significant communication-related inequities. Ongoing efforts are needed to promote equitable communication with this population and should consider the unique role of residents.

Types of diagnostic errors reported by paediatric emergency providers in a global paediatric emergency care research network.

BACKGROUND: Diagnostic errors, reframed as missed opportunities for improving diagnosis (MOIDs), are poorly understood in the paediatric emergency department (ED) setting. We investigated the clinical experience, harm and contributing factors related to MOIDs reported by physicians working in paediatric EDs. METHODS: We developed a web-based survey in which physicians participating in the international Paediatric Emergency Research Network representing five out of six WHO regions, described examples of MOIDs involving their own or a colleague's patients. Respondents provided case summaries and answered questions regarding harm and factors contributing to the event. RESULTS: Of 1594 physicians surveyed, 412 (25.8%) responded (mean age=43 years (SD=9.2), 42.0% female, mean years in practice=12 (SD=9.0)). Patient presentations involving MOIDs had common undifferentiated symptoms at initial presentation, including abdominal pain (21.1%), fever (17.2%) and vomiting (16.5%). Patients were discharged from the ED with commonly reported diagnoses, including acute gastroenteritis (16.7%), viral syndrome (10.2%) and constipation (7.0%). Most reported MOIDs (65%) were detected on ED return visits (46% within 24 hours and 76% within 72 hours). The most common reported MOID was appendicitis (11.4%), followed by brain tumour (4.4%), meningitis (4.4%) and non-accidental trauma (4.1%). More than half (59.1%) of the reported MOIDs involved the patient/parent-provider encounter (eg, misinterpreted/ignored history or an incomplete/inadequate physical examination). Types of MOIDs and contributing factors did not differ significantly between countries. More than half of patients had either moderate (48.7%) or major (10%) harm due to the MOID. CONCLUSIONS: An international cohort of paediatric ED physicians reported several MOIDs, often in children who presented to the ED with common undifferentiated symptoms. Many of these were related to patient/parent-provider interaction factors such as suboptimal history and physical examination. Physicians' personal experiences offer an underexplored source for investigating and mitigating diagnostic errors in the paediatric ED.

Clinical pathways and diagnostic reasoning: A qualitative study of pediatric residents' and hospitalists' perceptions.

BACKGROUND: Clinical pathways are evidence-based guidelines adapted to local settings. They have been shown to improve patient outcomes and reduce resource utilization. However, it is unknown how physicians integrate clinical pathways into their clinical reasoning. METHODS: We conducted a single-center qualitative study involving one-on-one semi-structured interviews of pediatric residents and pediatric hospitalist attendings between August 2021 and March 2022. Interviews were audio-recorded and professionally transcribed. We utilized a qualitative descriptive framework to code data and identify themes. RESULTS: We interviewed 15 pediatric residents and 12 pediatric hospitalists. Thematic analysis of interview transcripts revealed four themes related to physician utilization of and experience with clinical pathways: (1) utility as a tool, (2) means of standardizing care, (3) reflection of institutional culture, and (4) element of the dynamic relationship with the clinician diagnostic process. These themes were generally common to both residents and attending physicians; however, some differences existed and are noted when they occurred. CONCLUSIONS: Clinical pathways are part of many clinicians' diagnostic processes. Pathways can standardize care, influence the diagnostic process, and express local institutional culture. Further research is required to ascertain the optimal clinical pathway design to augment and not inhibit the clinician's diagnostic process.

Applying a diagnostic excellence framework to assess opportunities to improve recognition of child physical abuse.

OBJECTIVES: Diagnostic excellence is an important domain of healthcare quality. Delays in diagnosis have been described in 20-30% of children with abusive injuries. Despite the well characterized epidemiology, improvement strategies remain elusive. We sought to assess the applicability of diagnostic improvement instruments to cases of non-accidental trauma and to identify potential opportunities for system improvement in child physical abuse diagnosis. METHODS: We purposefully sampled 10 cases identified as having potential for system level interventions and in which the child had prior outpatient encounters to review. Experts in pediatrics, child abuse, and diagnostic improvement independently reviewed each case and completed SaferDx, a validated instrument used to evaluate the diagnostic process. Cases were subsequently discussed to map potential opportunities for improving the diagnostic process to the DEER Taxonomy, which classifies opportunities by type and phase of the diagnostic process. RESULTS: The most frequent improvement opportunities identified by the SaferDx were in recognition of potential alarm symptoms and in expanding differential diagnosis (5 of 10 cases). The most frequent DEER taxonomy process opportunities were in history taking (8 of 10) and hypothesis generation (7 of 10). Discussion elicited additional opportunities in reconsideration of provisional diagnoses, understanding biopsychosocial risk, and addressing information scatter within the electronic health record (EHR). CONCLUSIONS: Applying a diagnostic excellence framework facilitated identification of systems opportunities to improve recognition of child abuse including integration of EHR information to support recognition of alarm symptoms, collaboration to support vulnerable families, and communication about diagnostic reasoning.

Implementation of a Multidisciplinary Debriefing Process for Pediatric Ward Deterioration Events.

OBJECTIVES: Event debriefing has established benefit, but its adoption is poorly characterized among pediatric ward providers. To improve patient safety, our hospital restructured its debriefing process for ward deterioration events culminating in ICU transfer. The aim of this study was to describe this process' implementation. METHODS: In the restructured process, multidisciplinary ward providers are expected to debrief all ICU transfers. We conducted a multimethod analysis using facilitative guides completed by debriefing participants. Monthly debriefing completion served as an adoption metric. RESULTS: Between March 2019 and February 2020, providers across 9 wards performed debriefing for 134 of 312 PICU transfers (43%). Bedside nurses participated most frequently (117 debriefings [87%]). There was no significant difference in debriefing by unit, acuity, season, or nurse staffing. Compared with units fully staffed by rotational frontline clinicians (FLCs; eg, resident physicians), units with dedicated FLCs whose responsibilities are primarily limited to that unit (eg, oncology hospitalists) completed significantly more monthly debriefings (average [SD] 57% [30%] vs 33% [28%] of PICU transfers; P = .004). FLC participation was also higher on these units (50% of debriefings [37%] vs 24% [37%]; P = .014). Through qualitative analysis, we identified distinct debriefing themes, with teaming activities such as communication cited most often. CONCLUSIONS: Implementation of a multidisciplinary debriefing process for ward deterioration events culminating in ICU transfer was associated with differential adoption across providers and FLC staffing models but not acuity or nurse staffing. Teaming activities were a debriefing priority. Future study will assess patient safety outcomes.

An Operational Framework to Study Diagnostic Errors in Emergency Departments: Findings From A Consensus Panel.

OBJECTIVE: To create an operational definition and framework to study diagnostic error in the emergency department setting. METHODS: We convened a 17-member multidisciplinary panel with expertise in general and pediatric emergency medicine, nursing, patient safety, informatics, cognitive psychology, social sciences, human factors, and risk management and a patient/caregiver advocate. We used a modified nominal group technique to develop a shared understanding to operationally define diagnostic errors in emergency care and modify the National Academies of Sciences, Engineering, and Medicine's conceptual process framework to this setting. RESULTS: The expert panel defined diagnostic errors as "a divergence from evidence-based processes that increases the risk of poor outcomes despite the availability of sufficient information to provide a timely and accurate explanation of the patient's health problem(s)." Diagnostic processes include tasks related to (a) acuity recognition, information and synthesis, evaluation coordination, and (b) communication with patients/caregivers and other diagnostic team members. The expert panel also modified the National Academies of Sciences, Engineering, and Medicine's diagnostic process framework to incorporate influence of mode of arrival, triage level, and interventions during emergency care and underscored the importance of outcome feedback to emergency department providers to promote learning and improvement related to diagnosis. CONCLUSIONS: The proposed operational definition and modified diagnostic process framework can potentially inform the development of measurement tools and strategies to study the epidemiology and interventions to improve emergency care diagnosis.

A Framework for Quality Assurance of Pediatric Revisits to the Emergency Department.

BACKGROUND: Emergency department return visits significantly impact medical costs and patient flow. A comprehensive approach to understanding these patients is required to identify deficits in care, system level inefficiencies, and improve diagnosis specific management protocols. We aimed to identify factors needed to successfully analyze return visits to explore root causes leading to unplanned returns and inform system-level improvements. METHODS: A multidisciplinary committee collaborated to develop a quality review process for return visits within 72 hours to our pediatric emergency department that were then subsequently admitted to the hospital. The committee developed methodology and a web-based tool for chart review and analysis. RESULTS: Of 197,076 ED visits (159,164 discharged at initial visit), 5390 (3.4%) patients were discharged and represented to the ED within 72 hours and 1658 (1.0%) of those resulted in admission. Using defined criteria, approximately one third (n = 564) of revisits with admission were identified for chart review. Reason for revisit included natural progression of disease (67.6%), new condition or problem (11.2%), diagnostic error (6.9%), and scheduled or planned readmissions (3.5%). All diagnostic errors had not been previously identified by ED leadership. Of the reviewed cases, most were not preventable (84.0%); however, a number of system-level actions resulted from discussion of the potentially preventable revisits. CONCLUSIONS: Seventy-two-hour ED revisits were efficiently and systematically categorized with determination of root causes and preventability. This process resulted in shared provider-level feedback, identifying trends in revisits, and implementation of system-level actions, therefore, encouraging other institutions to adopt a similar process.

Identifying trigger concepts to screen emergency department visits for diagnostic errors.

OBJECTIVES: The diagnostic process is a vital component of safe and effective emergency department (ED) care. There are no standardized methods for identifying or reliably monitoring diagnostic errors in the ED, impeding efforts to enhance diagnostic safety. We sought to identify trigger concepts to screen ED records for diagnostic errors and describe how they can be used as a measurement strategy to identify and reduce preventable diagnostic harm. METHODS: We conducted a literature review and surveyed ED directors to compile a list of potential electronic health record (EHR) trigger (e-triggers) and non-EHR based concepts. We convened a multidisciplinary expert panel to build consensus on trigger concepts to identify and reduce preventable diagnostic harm in the ED. RESULTS: Six e-trigger and five non-EHR based concepts were selected by the expert panel. E-trigger concepts included: unscheduled ED return to ED resulting in hospital admission, death following ED visit, care escalation, high-risk conditions based on symptom-disease dyads, return visits with new diagnostic/therapeutic interventions, and change of treating service after admission. Non-EHR based signals included: cases from mortality/morbidity conferences, risk management/safety office referrals, ED medical director case referrals, patient complaints, and radiology/laboratory misreads and callbacks. The panel suggested further refinements to aid future research in defining diagnostic error epidemiology in ED settings. CONCLUSIONS: We identified a set of e-trigger concepts and non-EHR based signals that could be developed further to screen ED visits for diagnostic safety events. With additional evaluation, trigger-based methods can be used as tools to monitor and improve ED diagnostic performance.

Improving Disposition Decision-Making for Pediatric Diabetic Ketoacidosis: A Quality Improvement Study.

INTRODUCTION: In many centers, children with diabetic ketoacidosis (DKA) receive care either in an endocrinology ward or a pediatric intensive care unit (PICU). We conducted a quality improvement (QI) initiative to reduce potentially avoidable PICU admissions of children with DKA without increasing endocrinology ward-to-PICU transfers. METHODS: A survey of providers demonstrated opportunities to increase awareness of institutional criteria for PICU admissions of children with DKA. We created an electronic health record (EHR) dot-phrase, prepopulated with these criteria, and placed a note in the EHR for all patients with DKA as a reference for all providers. An EHR-based data report was created to monitor the disposition of DKA patients and the use of the dot-phrase (process measure). The primary outcome measure was the potentially avoidable PICU admissions for patients with DKA. Endocrinology ward-to-PICU transfers were tracked as a balancing measure to ensure safe disposition. RESULTS: After the implementation of the dot-phrase, use was variable, but averaged 33.4% over 1 year. The percentage of DKA admissions classified as potentially avoidable PICU stays decreased from 4.1% to 0.5%, with a concurrent decrease in the total percentage of PICU admissions for DKA from 19.1% to 8.4%. The percentage of endocrinology ward-to-PICU transfers also declined from 0.8% to 0%. CONCLUSIONS: A novel EHR-based intervention increasing awareness and documentation of established pediatric DKA management guidelines can be used to safely reduce PICU admissions for DKA without increasing the rate of endocrinology ward-to-intensive care unit transfers.

Demonstrating the value of postgraduate fellowships for physicians in quality improvement and patient safety.

BACKGROUND: Academic fellowships in quality improvement (QI) and patient safety (PS) have emerged as one strategy to fill a need for physicians who possess this expertise. The authors aimed to characterise the impact of two such programmes on the graduates and their value to the institutions in which they are housed. METHODS: In 2018, a qualitative study of two US QIPS postgraduate fellowship programmes was conducted. Graduates' demographics and titles were collected from programme files,while perspectives of the graduates and their institutional mentors were collected through individual interviews and analysed using thematic analysis. RESULTS: Twenty-eight out of 31 graduates (90%) and 16 out of 17 (94%) mentors participated in the study across both institutions. At a median of 3 years (IQR 2-4) postgraduation, QIPS fellowship programme graduates' effort distribution was: 50% clinical care (IQR 30-61.8), 48% QIPS administration (IQR 20-60), 28% QIPS research (IQR 17.5-50) and 15% education (7.1-30.4). 68% of graduates were hired in the health system where they trained. Graduates described learning the requisite hard and soft skills to succeed in QIPS roles. Mentors described the impact of the programme on patient outcomes and increasing the acceptability of the field within academic medicine culture. CONCLUSION: Graduates from two QIPS fellowship programmes and their mentors perceive programmatic benefits related to individual career goal attainment and institutional impact. The results and conceptual framework presented here may be useful to other academic medical centres seeking to develop fellowships for advanced physician training programmes in QIPS.

Quality Improvement and Safety in Pediatric Emergency Medicine.

Pediatric emergency medicine quality work continues to focus on the National Academies of Sciences, Engineering, and Medicine's 6 domains of quality, with a need for specific emphasis on equity and patient centeredness. Adopting the principles of high-reliability organizations, pediatric emergency departments should become increasing transparent with benchmarking and collaboration across institutions in order to develop an infrastructure for quality and safety to improve the care of pediatric patients in the emergency department.

Using Immersive Simulation to Engage Pediatric Residents in Difficult Conversations and the Disclosure of Patient Safety Events.

Background Full disclosure of patient safety events (PSE) is desired by patients and their families, is required by the Joint Commission and many state laws, and is vital to improving patient outcomes. A key barrier to consistent disclosure of patient safety events is a self-reported lack of proper training. Physicians must be trained to recognize when a PSE has occurred and effectively carry out disclosure, all while caring for a patient who is actively experiencing the consequences of an unintended outcome. Immersive simulation provides the opportunity to practice this complex skill. Objective To develop and evaluate a simulation-based workshop for pediatric residents on the disclosure of patient safety events. Methods A workshop in PSE disclosure was developed according to literature review, expert consultation, and feedback from hospital administration. The three-hour workshop included a simulated PSE with a subsequent standardized debriefing, interactive didactic session, and additional simulation-based hands-on practice in disclosure. Participants completed an anonymous survey at one-week and three-months post workshop, assessing workshop satisfaction, subsequent clinical experience, and perceived change to their practice. Results During the one-year study period, 27/31 (87.0%) second year residents completed the workshop. At the one-week follow-up, all study participants reported increased confidence and preparedness in their ability to lead the initial disclosure conversation. All study participants felt that the simulated scenarios were realistic and relevant to their current clinical duties and 33.3% (n=9) stated that they would like to repeat this workshop prior to completion of their training. At the three-month follow-up, 29.6% (N=8) of study participants reported involvement in the disclosure of a patient safety event since the workshop with all eight reporting feeling adequately prepared by the workshop for this experience. Study participants indicated that post training they were more likely to engage the attending physician, risk management and patient relations in the disclosure conversation (p <=0.05). The estimated cost of this simulation training for 27 residents was $6,993, not accounting for the 39 hours per clinician facilitator. Conclusions Immersive simulation is uniquely suited for teaching difficult conversation skills that are encountered during acute care, including the disclosure of patient safety events. While hands-on practice is critical, faculty and simulation resources required for continued implementation may not be sustainable long-term. Future training curricula should leverage creative and innovative adult-learning techniques to reach a wide range of members of the care team with less resource utilization.

Incident Reporting to Improve Patient Safety: The Effects of Process Variance on Pediatric Patient Safety in the Emergency Department.

OBJECTIVE: Medical errors threaten patient safety, especially in the pediatric emergency department (ED) where overcrowding, multiple handoffs, and workflow interruptions are common. Errors related to process variance involve situations that are not consistent with standard ED operations or routine patient care. SETTING/PARTICIPANTS: We performed a planned subanalysis of the Pediatric Emergency Care Applied Research Network incident reporting data classified as process variance events. Confidential deidentified incident reports (IRs) were collected and classified by 2 independent investigators. Events categorized as process variance were then subtyped for severity and contributing factors. Data were analyzed using descriptive statistics. OUTCOME MEASURES: The study intention was to describe and measure reported medical errors related to process variance in 17 EDs in the Pediatric Emergency Care Applied Research Network from 2007 to 2008. RESULTS: Between July 2007 and June 2008, 2906 eligible reports were reviewed. Process variance events were identified in 15.4% (447/2906). The majority were related to patient flow (35.4%), handoff communication (17.2%), and patient identification errors (15.9%). Most staff involved included nurses (47.9%) and physicians (28%); trainees were infrequently reported. The majority of events did not result in harm (65.7%); 17.9% (80/447) of cases were classified as unsafe conditions but did not reach the patient. Temporary harm requiring further treatment or hospitalization was reported in 5.6% (25/447). No events resulted in permanent harm, near death, or death. Contributing factors included human factors (92.1%), in particular handoff communication, interpersonal skills, and compliance with established procedures, and system-level errors (18.1%), including unclear or unavailable policies and inadequate staffing levels. CONCLUSIONS: Although process variance events accounted for approximately 1 in 6 reported safety events, very few led to patient harm. Because human and system-level factors contributed to most of these events, our data provide an insight into potential areas for further investigation and improvements to mitigate errors in the ED setting.

Predicting Low-Resource-Intensity Emergency Department Visits in Children.

OBJECTIVES: Interventions to reduce frequent emergency department (ED) use in children are often limited by the inability to predict future risk. We sought to develop a population-based model for predicting Medicaid-insured children at risk for high frequency (HF) of low-resource-intensity (LRI) ED visits. METHODS: We conducted a retrospective cohort analysis of Medicaid-insured children (aged 1-18 years) included in the MarketScan Medicaid database with ≥1 ED visit in 2013. LRI visits were defined as ED encounters with no laboratory testing, imaging, procedures, or hospitalization; and HF as ≥3 LRI ED visits within 365 days of the initial encounter. A generalized linear regression model was derived and validated using a split-sample approach. Validity testing was conducted examining model performance using 3 alternative definitions of LRI. RESULTS: Among 743,016 children with ≥1 ED visit in 2013, 5% experienced high-frequency LRI ED use, accounting for 21% of all LRI visits. Prior LRI ED use (2 visits: adjusted odds ratio = 3.5; 95% confidence interval, 3.3, 3.7; and ≥3 visits: adjusted odds ratio = 7.7; 95% confidence interval, 7.3, 8.1) and presence of ≥3 chronic conditions (adjusted odds ratio = 1.7; 95% confidence interval, 1.6, 1.8) were strongly associated with future HF-LRI ED use. A model incorporating patient characteristics and prior ED use predicted future HF-LRI ED utilization with an area under the curve of 0.74. CONCLUSIONS: Demographic characteristics and patterns of prior ED use can predict future risk of HF-LRI ED use in the following year. Interventions for reducing low-value ED use in these high-risk children should be considered.

Characteristics of Children Enrolled in Medicaid With High-Frequency Emergency Department Use.

BACKGROUND AND OBJECTIVES: Some children repeatedly use the emergency department (ED) at high levels. Among Medicaid-insured children with high-frequency ED use in 1 year, we sought to describe the characteristics of children who sustain high-frequency ED use over the following 2 years. METHODS: Retrospective longitudinal cohort study of 470 449 Medicaid-insured children appearing in the MarketScan Medicaid database, aged 1-16 years, with ≥1 ED discharges in 2012. Children with high ED use in 2012 (≥4 ED discharges) were followed through 2014 to identify characteristics associated with sustained high ED use (≥8 ED discharges in 2013-2014 combined). A generalized linear model was used to identify patient characteristics associated with sustained high ED use. RESULTS: A total of 39 945 children (8.5%) experienced high ED use in 2012, accounting for 25% of total ED visits in 2012. Sixteen percent of these children experienced sustained high ED use in the following 2 years. Adolescents (adjusted odds ratio [aOR]: 1.4 [95% confidence interval: 1.3-1.5]), disabled children (aOR: 1.3 [95% confidence interval: 1.1-1.5]), and children with 3 or more chronic conditions (aOR: 2.1, [95% confidence interval: 1.9-2.3]) experienced the highest likelihood for sustaining high ED use. CONCLUSIONS: One in 6 Medicaid-insured children with high ED use in a single year experienced sustained high levels of ED use over the next 2 years. Adolescents and individuals with multiple chronic conditions were most likely to have sustained high rates of ED use. Targeted interventions may be indicated to help reduce ED use among children at high risk.
