Discrete event simulation modelling to evaluate the impact of a quality improvement initiative on patient flow in a paediatric emergency department.

OBJECTIVE: We developed a discrete event simulation model to evaluate the impact on system flow of a quality improvement (QI) initiative that included a time-specific protocol to decrease the time to antibiotic delivery for children with cancer and central venous catheters who present to a paediatric ED with fever. METHODS: The model was based on prospective observations and retrospective review of ED processes during the maintenance phase of the QI initiative between January 2016 and June 2017 in a large, urban, academic children's hospital in New York City, USA. We compared waiting time for full evaluation (WT) and length of stay (LOS) between a model with and a model without the protocol. We then gradually increased the proportion of patients receiving the protocol in the model and recorded changes in WT and LOS. RESULTS: We validated model outputs against administrative data from 2016, with no statistically significant differences in average WT or LOS for any emergency severity index (ESI). There were no statistically significant differences in these flow metrics between the model with and the model without the protocol. By increasing the proportion of total patients receiving this protocol, from 0.2% to 1.3%, the WT increased by 2.8 min (95% CI: 0.6 to 5.0) and 7.6 min (95% CI: 2.0 to 13.2) for ESI 2 and ESI 3 patients, respectively. This represents a 14.0% increase in WT for ESI 3 patients. CONCLUSIONS: Simulation modelling facilitated the testing of system effects for a time-specific protocol implemented in a large, urban, academic paediatric ED, showing no significant impact on patient flow. The model suggests system resilience, demonstrating no detrimental effect on WT until there is a 7-fold increase in the proportion of patients receiving the protocol.

Pediatric Emergency Physicians' Comfort Level Providing Urgent Care for Adults on Telemedicine During the COVID-19 Pandemic: Experience at an Academic Medical Center.

OBJECTIVE: Our objectives were to assess the comfort level of pediatric emergency physicians (PEPs) providing urgent care to adult patients on telemedicine (APOTM) when redeployed during the coronavirus disease 2019 (COVID-19) pandemic, how it changed over time, and what resources were helpful.  Materials and methods: We conducted a retrospective pre-post cross-sectional survey of PEPs providing urgent care to APOTM with COVID-19 symptoms during the COVID-19 surge from March 12, 2020, to June 12, 2020 (the "care period") at two academic pediatric emergency departments in New York City. A retrospective chart review was also conducted. We include data on demographics of PEPs and adult patients; comfort level of PEPs providing urgent care to APOTM with COVID-19 symptoms pre- and post-three-month care period and effective resources. RESULTS: Sixty-five PEPs provided urgent care to 1515 APOTM with COVID-19 symptoms during the care period. Pre-pandemic, 22/43 (51%) of responders feared caring for APOTM; 6/43 (14%) were comfortable. At the end of the care period, 25/42 (58%) of the responders stated they were comfortable caring for these patients. Factors associated with increased comfort level were: increased volume of patients over time, treatment algorithms, group support via electronic communication, and real-time back-up by a general emergency medicine (GEM) physician. Reduced medicolegal liability was also cited. CONCLUSION:  With minimal additional training and resources, PEPs can increase their comfort to provide urgent care to APOTM with COVID-19 symptoms. As future pandemics may disproportionately affect certain patient populations (adults versus pediatrics), interventions such as treatment algorithms, group support via emails and texts, and sub-specialty backup should be incorporated into redeployment plans for urgent care telemedicine programs. Future research is needed to determine the adaptability of other medical specialties to cross-cover a different specialty from their own if needed.

Parental reasons for utilization of an urban pediatric emergency department during the 2009 H1N1 influenza epidemic.

OBJECTIVE: The objective of the study was to understand the utilization of the pediatric emergency department (PED) of an academic hospital during regular primary care office hours during the 2009 H1N1 epidemic. Children with a usual source of care presenting for influenza-like illness (ILI) symptoms were compared with those presenting with other symptoms. METHODS: During the 2009 H1N1 outbreak, parents visiting a PED in a low-income area in New York City in June 2009 were surveyed using open- and close-ended questions. Sociodemographic factors and reasons for seeking care in the PED rather than their usual source of care were compared between groups. RESULTS: There were no sociodemographic differences among children brought to the PED for ILI and those brought for other presenting symptoms. Those families with a child with ILI symptoms were less likely to report urgency as the primary reason they brought their child to the PED. A common reason reported for coming to the PED was limited access to care. In further exploration of limited access, parents with a child with ILI symptoms were more likely to report that their usual source of care did not have any evening and/or weekend hours, and they did not know how to reach their provider after hours. CONCLUSIONS: Enhancing access to primary care settings and encouraging parents to use their primary care providers might reduce the utilization of the PED for nonurgent problems during epidemics.

Change in parental reasons for use of an urban pediatric emergency department in the past decade.

OBJECTIVE: To assess changes over the past decade in parental reasons associated with nonurgent visits to pediatric emergency departments (PEDs) during regular primary care office hours. METHODS: Secondary analysis of cross-sectional surveys of families of children younger than 3 years visiting a PED in a low-socioeconomic area in New York City conducted in 1997 and 2006. We performed multivariable analyses to assess differences in parental reported reasons for PED use over the period, controlling for sociodemographic factors. RESULTS: Most children (95.6%) had a usual source of care across both periods. Compared with those seen in 1997, children seen in 2006 were far less likely to be brought to the PED during regular primary care office hours for parental perceived urgency (adjusted odds ratio [AOR], 0.076; 95% confidence interval [CI], 0.024-0.24; P < 0.001). At the same time, these children were more likely to be brought to the PED for limited access to their usual source of care (AOR, 3.35; 95% CI, 1.24-9.02; P < 0.05) and greater trust in the medical expertise of the PED (AOR, 5.95 95% CI, 1.20-29.45; P < 0.05). CONCLUSIONS: Over the last decade, despite the presence of a usual source of care, a greater number of parents report visiting this urban PED during regular office hours for reasons unrelated to parental perceived urgency. Limited access to care and greater trust in the medical expertise available in PEDs have played important roles. Approaches to decreasing nonurgent visits must take into account all of these factors.

Provider-Level and Hospital-Level Factors and Process Measures of Quality Care Delivered in Pediatric Emergency Departments.

OBJECTIVE: Differences in the quality of emergency department (ED) care are often attributed to nonclinical factors such as variations in the structure, systems, and processes of care. Few studies have examined these associations among children. We aimed to determine whether process measures of quality of care delivered to patients receiving care in children's hospital EDs were associated with physician-level or hospital-level factors. METHODS: We included children (<18 years old) who presented to any of the 12 EDs participating in the Pediatric Emergency Care Applied Research Network (PECARN) between January 2011 and December 2011. We measured quality of care from medical record reviews using a previously validated implicit review instrument with a summary score ranging from 5 to 35, and examined associations between process measures of quality and physician- and hospital-level factors using a mixed-effects linear regression model adjusted for patient case-mix, with hospital site as a random effect. RESULTS: Among the 620 ED encounters reviewed, we did not find process measures of quality to be associated with any physician-level factors such as physician sex, years since medical school graduation, or physician training. We found, however, that process measures of quality were positively associated with delivery at freestanding children's hospitals (1.96 points higher in quality compared to nonfreestanding status, 95% confidence interval: 0.49, 3.43) and negatively associated with higher annual ED patient volume (-0.03 points per thousand patients, 95% confidence interval: -0.05, -0.01). CONCLUSION: Process measures of quality of care delivered to children were higher among patients treated at freestanding children's hospitals but lower among patients treated at higher volume EDs.

Referral and resource use patterns for psychiatric-related visits to pediatric emergency departments.

OBJECTIVE: To describe the patterns of referral and use of resources for patients with psychiatric-related visits presenting to pediatric emergency departments (EDs) in a pediatric research network. METHODS: We conducted a retrospective chart review of a random sample of patients (approximately 10 charts per month per site) who presented with psychiatric-related visits in 2002 to 4 pediatric EDs in the Pediatric Emergency Care Applied Research Network. Emergency department resource use variables evaluated included the use of consultation services, restraints, and laboratory tests as well as ED length of stay. RESULTS: We reviewed 462 patient visits with a psychiatric-related ED diagnosis. Mean (SD) age was 12.8 (3.7) years, 52% were male, and 49% were African American. The most common chief complaints were suicidality (47%), aggression/agitation (42%), and anxiety/depression (27%), alone or in combination. Ninety percent of patients (range across sites, 83%-94%) had a mental health consult in the ED, 5% were restrained (range, 3%-9%), and 35% had a laboratory test performed (range, 15%-63%). Mean (SD) ED length of stay was 5.1 (5.4) hours, and 52% were admitted (93% to a psychiatric bed, including transfers to separate psychiatric facilities). CONCLUSIONS: Children with psychiatric-related visits seem to require substantial ED resources. Interventions are needed to reduce the burden on the ED by increasing the linkage to mental health services, particularly for suicidal youths.

Epidemiology of psychiatric-related visits to emergency departments in a multicenter collaborative research pediatric network.

OBJECTIVES: Describe the epidemiology of pediatric psychiatric-related visits to emergency departments participating in the Pediatric Emergency Care Applied Research Network. METHODS: Retrospective analysis of emergency department presentations for psychiatric-related visits (International Classification of Diseases, Ninth Revision, codes 290.0-314.90) for years 2003 to 2005 at 24 participating Pediatric Emergency Care Applied Research Network hospitals. All patients who had psychiatric-related emergency department visits aged 19 years or younger were eligible. Age, sex, race, ethnicity, insurance status, mode of arrival, length of stay, and disposition were described for psychiatric-related visits and compared with non-psychiatric-related visits. RESULTS: Pediatric psychiatric-related visits accounted for 3.3% of all participating emergency department visits (84,973/2,580,299). Patients with psychiatric-related visits were older (mean +/- SD age, 12.7 +/- 3.9 years vs. 5.9 +/- 5.6 years, P < 0.001), had a higher rate ambulance arrival (19.4% vs 8.2%, P < 0.0001), had a longer median length of stay (3.2 vs 2.1 hours, P < 0.0001), and had a higher rate of admission (30.5% vs 11.2%, P < 0.0001) when compared with non-psychiatric-related patient presentations. Older age, female sex, white race, ambulance arrival, and governmental insurance were factors independently associated with admission or transfer from the emergency department for psychiatric-related visits in multivariate regression analyses. CONCLUSIONS: Pediatric psychiatric-related visits require more prehospital and emergency department resources and have higher admission/transfer rates than non-psychiatric-related visits within a large national pediatric emergency network.

Patient-level Factors and the Quality of Care Delivered in Pediatric Emergency Departments.

OBJECTIVE: Quality of care delivered to adult patients in the emergency department (ED) is often associated with demographic and clinical factors such as a patient's race/ethnicity and insurance status. We sought to determine whether the quality of care delivered to children in the ED was associated with a variety of patient-level factors. METHODS: This was a retrospective, observational cohort study. Pediatric patients (<18 years) who received care between January 2011 and December 2011 at one of 12 EDs participating in the Pediatric Emergency Care Applied Research Network (PECARN) were included. We analyzed demographic factors (including age, sex, and payment source) and clinical factors (including triage, chief complaint, and severity of illness). We measured quality of care using a previously validated implicit review instrument using chart review with a summary score that ranged from 5 to 35. We examined associations between demographic and clinical factors and quality of care using a hierarchical multivariable linear regression model with hospital site as a random effect. RESULTS: In the multivariable model, among the 620 ED encounters reviewed, we did not find any association between patient age, sex, race/ethnicity, and payment source and the quality of care delivered. However, we did find that some chief complaint categories were significantly associated with lower than average quality of care, including fever (-0.65 points in quality, 95% confidence interval [CI] = -1.24 to -0.06) and upper respiratory symptoms (-0.68 points in quality, 95% CI = -1.30 to -0.07). CONCLUSION: We found that quality of ED care delivered to children among a cohort of 12 EDs participating in the PECARN was high and did not differ by patient age, sex, race/ethnicity, and payment source, but did vary by the presenting chief complaint.

Implicit Review Instrument to Evaluate Quality of Care Delivered by Physicians to Children in Emergency Departments.

OBJECTIVE: To evaluate the consistency, reliability, and validity of an implicit review instrument that measures the quality of care provided to children in the emergency department (ED). DATA SOURCES/STUDY SETTING: Medical records of randomly selected children from 12 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). STUDY DESIGN: Eight pediatric emergency medicine physicians applied the instrument to 620 medical records. DATA COLLECTION/EXTRACTION METHODS: We determined internal consistency using Cronbach's alpha and inter-rater reliability using the intraclass correlation coefficient (ICC). We evaluated the validity of the instrument by correlating scores with four condition-specific explicit review instruments. PRINCIPAL FINDINGS: Individual reviewers' Cronbach's alpha had a mean of 0.85 with a range of 0.76-0.97; overall Cronbach's alpha was 0.90. The ICC was 0.49 for the summary score with a range from 0.40 to 0.46. Correlations between the quality of care score and the four condition-specific explicit review scores ranged from 0.24 to 0.38. CONCLUSIONS: The quality of care instrument demonstrated good internal consistency, moderate inter-rater reliability, high inter-rater agreement, and evidence supporting validity. The instrument could be useful for systems' assessment and research in evaluating the care delivered to children in the ED.
