Effect of a triage team on length of stay in a pediatric emergency department

Interventions to improve emergency department throughput and care delivery indicators: A systematic review and meta-analysis

BACKGROUND

Emergency department (ED) crowding has repercussions on acute care, contributing to prolonged wait times, length of stay, and left without being seen (LWBS). These indicators are regarded as systemic shortcomings, reflecting a failure to provide equitable and accessible acute care. The objective was to evaluate the effectiveness of interventions aimed at improving ED care delivery indicators.

METHODS

This was a systematic review and meta-analysis of randomized controlled trials (RCTs) assessing ED interventions aimed at reducing key metrics of time to provider (TTP), time to disposition (TTD), and LWBS. We excluded disease-specific trials (e.g., stroke). We used Cochrane's revised tool to assess the risk of bias and Grading of Recommendations, Assessment, Development, and Evaluations to rate the quality of evidence. The meta-analysis was performed using a random-effects model and Cochrane Q test for heterogeneity. Data were summarized as means (±SD) for continuous variables and risk ratios (RR) with 95% confidence intervals (CIs).

RESULTS

We searched MEDLINE, EMBASE, and other major databases. A total of 1850 references were scanned and 20 RCTs were selected for inclusion. The trials reported at least one of the three outcomes of TTD, TTP, or LWBS. Most interventions focused on triage liaison physician and point-of-care (POC) testing. Others included upfront expedited workup (ordering tests before full evaluation by a provider), scribes, triage kiosks, and sending notifications to consultants or residents. POC testing decreased TTD by an average of 5-96 min (high heterogeneity) but slightly increased TTP by a mean difference of 2 min (95% CI 0.6-4 min). Utilizing a triage liaison physician reduced TTD by 28 min (95% CI 19-37 min; moderate-quality evidence) and was more effective in reducing LWBS than routine triage (RR 0.76, 95% CI 0.66-0.88; moderate quality).

CONCLUSIONS

Operational strategies such as POC testing and triage liaison physicians could mitigate the impact of ED crowding and appear to be effective. The current evidence supports these strategies when tailored to the appropriate practice environment.

Non-urgent presentations to the paediatric emergency department: a literature review

It is estimated that between 58% and 82% of children and young people who present to paediatric emergency department (PEDs) have a non-urgent condition. This systematic review of the literature explores why parents of children with non-urgent conditions present to the PED rather than to community healthcare services. Five databases were searched for studies on children and young people's presentations to the PED for the treatment of a non-urgent condition, as identified by a low priority triage code. This article describes and discusses the findings of the 18 included studies.

Factors Affecting Length of Stay in Pediatric Emergency Department in a Teaching Hospital in Saudi Arabia

Background

Decreasing the number of Emergency Department patient visits for treatment, especially in non-urgent cases, is an international healthcare goal. The same applies for pediatric emergency rooms where the utilization of ED is much more than adults.

Objective

We aim to measure the length of stay for all pediatric patients and examine the factors influencing it.

Methods

A retrospective chart review study was conducted at the pediatric ED of King Fahd Hospital in the Eastern Province of Saudi Arabia. The study included all patients presented to the pediatric ED, between January 1, 2018, and December 31, 2018, aged from 1 day to < 14 years old. Data included patient's age, sex, season in which the patient presented in, chief complaint, time of presentation, and whether admission to the hospital ward was collected.

Results

The total number of patients was 37,613. The median LOS was 100, interquartile range (IQR) = 53 - 272 minutes. Male pediatric patients were (55.12%). Among all patients, (32.04%) were toddlers, followed by school aged children (25.05%). The ER received more patients during the winter months followed by summer (32.92% and 24.72%, respectively). Fever was the most common complaint for all patients combined. For prolonged LOS patients, the most common complaints were respiratory related (23.44%). Pre-school children and school aged children were found to have a 5.49% and a 7.93% increased LOS when compared to toddlers (95% CI = 2.52 - 8.53, and 95% CI = 5.01 - 10.93, respectively). Summer was associated with a statistically significant increased LOS (% change = 28.92, 95% CI = 25.53 - 32.40). Morning shift was found to have a 7.89% increased LOS when compared to the evening shift. The highest increase in LOS was attributed to haematology related complaints (% change = 108.32, 95% CI = 85.69 - 133.71).

Conclusion

Several pediatric LOS predicting factors have been identified; morning arrival, and presentation during summertime. Systemic factors such as staffing, and infrastructure can be modified and may affect the length of stay of patients. The implementation of these strategies and the evaluation of their impact on the length of stay in the pediatric emergency department require further investigation.

Does the Role of A Rapid Triage Provider Improve Pain Control in an Academic Pediatric Emergency Department?

Pediatric pain control in the emergency department (ED) remains problematic. This quantifiable metric may be positively affected by the utilization of a rapid triage provider (RTP). This is a retrospective case control study of pediatric patients requiring either ketorelac intravenous (IV) or morphine IV for painful conditions. Patients in the control group were managed according to standard nursing-driven triage process. Patients in the RTP group were seen by the standard triage team as well as by the RTP.We identified 114 patients who required IV pain medications. The mean time from arrival to pain medication administration for the RTP group as compared with the control group was 47 and 64 minutes (P = 0.02). Similarly, the mean time from arrival to IV pain medication order placement was 15 and 43 minutes (P < 0.01). An RTP improves pain control in the pediatric ED via more efficient order placement and IV pain medication administration.

Defining "Swarming" as a New Model to Optimize Efficiency and Education in an Academic Emergency Department

BACKGROUND

Academic emergency medicine is a constant balance between efficiency and education. We developed a new model called swarming, where the bedside nurse, resident, and attending/fellow simultaneously evaluate the patient, including initial vital signs, bedside triage, focused history and physical examination, and discussion of the treatment plan, thus creating a shared mental model.

OBJECTIVES

To combine perceptions from trainee physicians, supervising physicians, nurses, and families with in vivo measurements of emergency department swarms to better conceptualize the swarming model.

METHODS

This mixed methods study was conducted using a convergent design. Qualitative data from focus groups with nurses, residents, and attendings/fellows were analyzed using directed content analysis. Swarming encounters were observed in real time; durations of key aspects and family satisfaction scores were analyzed using descriptive statistics. The qualitative and quantitative findings were integrated a posteriori.

RESULTS

From the focus group data, 54 unique codes were identified, which were grouped together into five larger themes. From 39 swarms, mean (±SD) time (minutes) spent in patient rooms: nurses = 6.8 (±3.0), residents = 10.4 (±4.1), and attendings/fellows = 9.4 (±4.3). Electronic documentation was included in 67% of swarms, and 39% included orders initiated at the bedside. Mean (±SD) family satisfaction was 4.8 (±0.7; Likert scale 1-5).

CONCLUSIONS

Swarming is currently implemented with significant variability but results in high provider and family satisfaction. There is also consensus among physicians that swarming improves trainee education in the emergency setting. The benefits and barriers to swarming are underscored by the unpredictable nature of the ED and the observed variability in implementation. Our findings provide a critical foundation for our efforts to refine, standardize, and appraise our swarming model.

Implementation of a Pediatric Emergency Triage System in Xiamen, China

Background:

Pediatric emergency rooms (PERs) in Chinese hospitals are perpetually full of sick and injured children because of the lack of sufficiently developed community hospitals and low access to family physicians. The aim of this study was to evaluate the clinical value of a new five-level Chinese pediatric emergency triage system (CPETS), modeled after the Canadian Triage System and Acuity Scale.

Methods:

In this study, we compared CPETS outcomes in our PER relative to those of the prior two-level system. Patients who visited our PER before (January 2013–June 2013) and after (January 2014–June 2014) the CPETS was implemented served as the control and experimental group, respectively. Patient flow, triage rates, triage accuracy, wait times (overall and for severe patients), and patient/family satisfaction were compared between the two groups.

Results:

Relative to the performance of the former system experienced by the control group, the CPETS experienced by the experimental group was associated with a reduced patient flow through the PER (Cox-Stuart test, t = 0, P < 0.05), a higher triage rate (93.40% vs. 90.75%; χ² = 801.546, P < 0.001), better triage accuracy (96.32% vs. 85.09%; χ² = 710.904, P < 0.001), shorter overall wait times (37.30 ± 13.80 min vs. 41.60 ± 15.40 min; t = 11.27, P < 0.001), markedly shorter wait times for severe patients (2.07 [0.65, 4.11] min vs. 3.23 [1.90,4.36] min; z = –2.057, P = 0.040), and higher family satisfaction rates (94.23% vs. 92.21%; χ² = 321.528, P < 0.001).

Conclusions:

Implementing the CPETS improved nurses’ abilities to triage severe patients and, thus, to deliver the urgent treatments more quickly. The system shunted nonurgent patients to outpatient care effectively, resulting in improved efficiency of PER health-care delivery.

Can Team Triage Improve Patient Flow in the Emergency Department? A Systematic Review and Meta-Analysis

This systematic review was performed as a feasibility study for revamping the triage service of an emergency department (ED) in a district hospital. In view of the overcrowding problem that plagues EDs worldwide, we reviewed evidence from randomized controlled trials (RCTs) to determine whether ED team triage improves patient flow in comparison with single-nurse triage. We measured improvement in patient flow in terms of the reduction in length of stay (LOS) or wait time (WT) for all ED patients. Adopting the Cochrane methodology, we searched and evaluated data sources for RCTs comparing patients assessed by an ED triage team, with patients receiving single-nurse triage at the same site. The data extracted were independently reviewed by 2 authors for inclusion and quality assessment. As for risk of bias across studies, there was an overall assessment of every outcome across the included studies according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria for RCTs. In total, 2,164 studies were identified and 2,106 were excluded on the basis of title/abstract, leaving 58 articles for full assessment. Four trials (all cluster RCTs) involving 14,772 patients (165 clusters) met the inclusion criteria. On the basis of our analysis, there was no statistically significant or clinically relevant reduction of LOS and WT for all patients in these studies. One study reported death as an outcome: Relative risk was 0.34 (95% CI [0.01, 8.24]), which suggested that team triage might reduce mortality. Overall, although we have found no conclusive evidence from RCTs to support the use of team triage for improving patient flow in the ED, the results need not deter nursing managers intending to introduce team triage for improving the morale of the triage nurse. However, they may need to consider economic and organizational factors, such as resource reallocation and staff receptiveness, in implementing the new practice.

Impact of clinical pharmacist intervention on length of stay in an acute admission unit: a cluster randomised study

Objectives

Physicians in acute admission units (AAUs) are obliged to obtain medication history and perform medication reconciliation, which is time consuming and often incomplete. Studies show that clinical pharmacists (CPs) can obtain accurate medication histories, but so far no studies have investigated the effect of this on time measures. Therefore, the objective of the present study was to investigate the effect of a CP intervention on length of stay (LOS) in an AAU.

Methods

The study was designed as a prospective, cluster randomised study. Weekdays were randomised to control or intervention. CP intervention consisted of obtaining medication history and performing medication reconciliation and review. The primary outcome was LOS in the AAU. Secondary outcomes were other time-related measures-for example, physicians' self-reported time spent on medication topics. Finally, the number of documented medications per patient was established.

Results

232 and 216 patients, respectively, were included on control (n=63) and intervention (n=63) days. The mean LOS was 342 (95% CI 323 to 362) min in the intervention group and 339 (95% CI 322 to 357) min in the control group, which was not statistically significantly different. Physicians spent on average 4.3 (95% CI 3.7 to 5.0) min in the intervention group and 7.5 (95% CI 6.6 to 8.5) min in the control group, corresponding to an overall reduction of 43.0% (95% CI 30.9% to 53.0%, p<0.001). The number of documented medications per patient was 10.0 (intervention group) and 8.8 (control group).

Conclusions

This study indicates that LOS in the AAU was not affected by CP intervention; however, physicians reported a significant reduction in time spent on medication topics.

Creating a leaner pediatric emergency department: how rapid design and testing of a front-end model led to decreased wait time

OBJECTIVE

To use Lean methodologies and the Model for Improvement to rapidly redesign and pilot test a new pediatric emergency department (ED) front-end model that reduces time to a licensed independent provider to 30 minutes or less.

METHODS

Lean improvement methodologies were applied during a 5-day multidisciplinary model of care redesign event. The new ED front-end model of care included: (1) placement of a registered nurse in the lobby; (2) direct patient rooming with elimination of traditional triage; 3) early documentation of home medications; 4) Team-based immediate assessment; 5) "early Initiation" providers to place orders when a team was not available. An observational, cohort controlled before-and-after study design was used. The new model was tested over 2 pilot periods and compared to a similar period of control days, defined as the "current state."

RESULTS

The ED census and patient acuity were similar during both pilot periods. Eighteen patients were included in pilot 1, and 80 patients were included in the expanded second pilot. Patients seen within 30 minutes improved from a baseline of 33% to 93% in pilot 2. Time to a licensed independent provider, to a room, and to visual assessment by a nurse all decreased. The largest decrease was in median time to provider, from 43 minutes in the current state to 7 minutes during pilot 2.

CONCLUSIONS

Rapid process improvement methodology was used to design and test a front-end model that reduced patient waiting time. Our experience demonstrates the feasibility of employing Lean principles and the Model for Improvement in actual practice environments to rapidly improve care delivery processes in pediatric emergency departments.

Patient throughput benefits of triage liaison providers are lost in a resource-neutral model: a prospective trial

OBJECTIVES

Patient throughput is an increasingly important cause of emergency department (ED) crowding. The authors previously reported shorter patient length of stay (LOS) when adding a triage liaison provider, which required additional personnel. Here, the objective was to evaluate the effect of moving a fast-track provider to the triage liaison role.

METHODS

This was a prospective observational before-and-after study design with predefined outcomes measures. A "standard staffing" situation (where an advanced practice provider staffed treatment rooms in the fast track) was compared with an advanced practice provider performing the triage liaison staffing role, with no additional staff. Eleven intervention ("triage liaison staffing") days were compared with 11 matched control ("standard staffing") days immediately preceding the intervention. Total LOS was measured for all adult Emergency Severity Index (ESI) 3, 4, and 5 patients (excluding behavioral health patients), and results were compared using Wilcoxon rank-sum and chi-square tests.

RESULTS

A total of 681 patients registered on control days and 599 on intervention days. There was no significant difference in total patient LOS: median = 273 minutes, interquartile range (IQR) 176 to 384 minutes on intervention days versus median = 253 minutes, IQR = 175 to 365 minutes on control days (p = 0.20). There was no difference in left-without-being-seen (LWBS) rates (n = 48, 7% on control days vs. n = 35, 6% on intervention days; p=0.38). Secondary analysis of only ESI 3 patients showed no difference in total LOS between periods (median = 284 minutes, IQR = 194 to 396 minutes on intervention days vs. median = 290 minutes, IQR = 217 to 397 minutes on control days; p = 0.22). There was, however, significantly greater total LOS for ESI 4 and 5 patients during the intervention period (median = 238 minutes, IQR = 124 to 350 minutes on intervention days vs. median = 192 minutes, IQR = 124 to 256 minutes on control days; p = 0.011).

CONCLUSIONS

The previously reported benefits on patient LOS and LWBS rates after adding a triage liaison (resource additive) were lost when that provider was moved from fast track to the triage role (resource neutral). While the triage liaison provider role may be a way to improve ED throughput when additional resources are available, as evidenced by our prior study, the triage liaison model itself does not appear to replace the staffing of treatment rooms, as evidenced by this study.

Traditional nurse triage vs physician telepresence in a pediatric ED

OBJECTIVES

The objective of the study is to compare traditional nurse triage (TNT) in a pediatric emergency department (PED) with physician telepresence (PTP).

METHODS

This is a prospective 2 × 2 crossover study with random assignment using a sample of walk-in patients seeking care in a PED at a large, tertiary care children's hospital, from May 2012 to January 2013. Outcomes of triage times, documentation errors, triage scores, and survey responses were compared between TNT and PTP. Comparison between PTP to actual treating PED physicians regarding the accuracy of ordering blood and urine tests, throat cultures, and radiologic imaging was also studied.

RESULTS

Paired samples t tests showed a statistically significant difference in triage time between TNT and PTP (P = .03) but no significant difference in documentation errors (P = .10). Triage scores of TNT were 71% accurate, compared with PTP, which were 95% accurate. Both parents and children had favorable scores regarding PTP, and most indicated that they would prefer PTP again at their next PED visit. Physician telepresence diagnostic ordering was comparable with the actual PED physician ordering, showing no statistical differences.

CONCLUSIONS

Using PTP technology to remotely perform triage is a feasible alternative to traditional nurse triage, with no clinically significant differences in time, triage scores, errors, and patient and parent satisfaction.

Effect of a physician assistant as triage liaison provider on patient throughput in an academic emergency department

OBJECTIVES

Overcapacity issues plague emergency departments (EDs). Studies suggest that triage liaison providers (TLPs) may shorten patient length of stay (LOS) and reduce the proportion of patients who leave without being seen (LWBS), but these results are not universal. Previous studies used physicians as TLPs. We evaluated whether a physician assistant (PA), acting as a TLP, would shorten LOS and decrease LWBS rates.

METHODS

The authors used an observational cohort controlled before-and-after study design with predefined outcome measures, comparing 8 pilot days to 8 control days. The TLP evaluated all Emergency Severity Index (ESI) level 3, 4, and 5 patients, excluding pediatric and behavioral health patients.

RESULTS

A total of 353 patients were included on pilot days and 371 on control days. LOS was shorter on pilot days than control days (median [interquartile range {IQR}] = 229 [168 to 303] minutes vs. 270 [187 to 372] minutes, p < 0.001). Waiting room times were similar between pilot and control days (median [IQR] = 69 [20 to 119] minutes vs. 70 [19 to 137] minutes, p = 0.408), but treatment room times were shorter (median [IQR] = 151 [92 to 223] minutes vs. 187 [110 to 254] minutes, p < 0.001). Finally, a lower proportion of patients LWBS on pilot days (1.4% vs. 9.7%, p < 0.001).

CONCLUSIONS

The addition of a PA as a TLP was associated with a 41-minute decrease in median total LOS and a lower proportion of patients who LWBS. The decrease in total LOS is likely attributable to the addition of the TLP, with patients having shorter duration in treatment rooms on pilot days compared to control days.
