System Stresses in 2 Pediatric Emergency Departments and 2 Pediatric Urgent Care Centers During the 2014 Enterovirus-D68 Outbreak.

OBJECTIVE: To describe the association of an unprecedented large-scale Enterovirus-D68 outbreak in 2014 with changes in patient volume and acuity and system stress in 2 pediatric emergency departments and 2 pediatric urgent care centers of a single children's hospital. METHODS: We compared measures of patient volume, acuity, and system stress during the 2014 Enterovirus-D68 outbreak and the corresponding dates of the previous year. RESULTS: Both settings experienced large census increases during the Enterovirus-D68 outbreak; patient census increased significantly more in the pediatric urgent care setting (20.3%) than in the pediatric emergency departments (14.3%). Both settings had significant increases in patient acuity. The proportion of pediatric emergency department patients requiring hospital admission increased; the proportion of patients who left the pediatric urgent care setting without being seen also increased. Although there was no emergency department inpatient boarding during the 2013 comparison period, 4.4% of admitted patients required emergency department boarding during the 2014 outbreak. There was no significant change in the mean length of stay or the probability that patient admission was to the pediatric intensive care unit. CONCLUSIONS: Both the pediatric emergency departments and the pediatric urgent care centers experienced increased patient volumes and acuity and significant system stress in association with the 2014 Enterovirus-D68 outbreak. These data will inform those planning resource allocation for future large-scale viral outbreaks.

Comparative Performance of Pediatric Weight Estimation Techniques: A Human Factor Errors Analysis.

OBJECTIVE: We compared performance characteristics of 7 weight estimation methods examining predictive performance and human factors errors. METHODS: This was a prospective study of 80 emergency care providers (raters) and 80 children aged 2 months to 16 years. Raters estimated weights in 5 children with the following 7 strategies: visual estimation, Advanced Pediatric Life Support, Luscombe and Owens, Broselow tape, devised weight estimation method, 2D Mercy TAPE (2DT), and 3D Mercy TAPE (3DT). Quantitative errors were determined by checking rater values against values returned with optimal method use. RESULTS: Four hundred rater-child pairings generated 2800 weight estimates. For all methods, rater-estimated weights were less accurate than weights derived by optimal application. Skill-based, perception, and judgment/decision error were observed. For visual estimation, weights were underestimated in most children. For Advanced Pediatric Life Support/Luscombe and Owens, order of operations markedly impacted errors with 23% of calculations requiring addition first performed incorrectly versus 9% of calculations requiring multiplication first. For Broselow tape, only 63% of cases were eligible for estimation with this device, yet raters assigned a weight in 96% of cases. For Devised Weight Estimation Method, 96% of overweight and 48% of obese children were classified as slim or average. For 2DT/3DT, the 2DT was prone to more errors most commonly use of the wrong side of the device (24%). The impact of rater characteristics on error was most pronounced for methods requiring calculation. CONCLUSIONS: Skill-based, perception, or judgment errors were observed in more than 1 of 20 cases. No singular strategy was used with 100% accuracy.

Outcomes of implementing rapid triage in the pediatric emergency department.

INTRODUCTION: Efficiency and effectiveness are often used as quality indicators in emergency departments. With an aim to improve patient throughput and departmental efficiency while decreasing left-without-being-seen (LWBS) rates, this two-group, pre-intervention, post-intervention study in a pediatric emergency department evaluated the outcomes of implementing rapid triage on arrival-to-triage time, fast track utilization, and LWBS. METHODS: We implemented rapid triage assessment integrating the Emergency Severity Index and fast track guidelines in our pediatric emergency department. Arrival-to-triage times were tracked for 1 month before and after the intervention (N = 13,910 patient visits) by recording the time the patient arrived in the department and time triage assessment was complete. Fast track utilization and LWBS rates were measured for all patients sequentially included in pre-intervention (n = 60,373) and post-intervention (n = 67,939) groups for 10 months. RESULTS: After the intervention, patients experienced a significant decrease in arrival-to-triage times compared with the pre-intervention group (P < .001), with most patients (88.3%) being triaged in less than 10 minutes after the intervention. Following implementation of fast track guidelines, patients were 14% more likely to be triaged to fast track compared with pre-intervention patients (odds ratio [OR] = 1.14, 95% confidence interval [CI] = 1.11-1.67). Additionally, patients with the lowest acuity were nearly 50% more likely to be triaged to fast track compared with pre-intervention patients (OR = 1.48, 95% CI = 1.35-1.63). Although LWBS rates were insignificant, overall acuity level of this group was lower in the post-intervention group. DISCUSSION: Although LWBS rates did not decrease with the intervention, implementation of a rapid triage system and fast track guidelines reduced arrival-to-triage times and decreased acuity in the LWBS population. Implementing rapid triage and fast track guidelines can affect nurse-sensitive patient outcomes related to safety and care delivery in a pediatric emergency department.
