Emergency Department Overcrowding and Ambulance Turnaround Time.

ABSTRACT:

Objective

The aims of this study were to describe overcrowding in regional emergency departments in Seoul, Korea and evaluate the effect of crowdedness on ambulance turnaround time.

Methods

This study was conducted between January 2010 and December 2010. Patients who were transported by 119-responding ambulances to 28 emergency centers within Seoul were eligible for enrollment. Overcrowding was defined as the average occupancy rate, which was equal to the average number of patients staying in an emergency department (ED) for 4 hours divided by the number of beds in the ED. After selecting groups for final analysis, multi-level regression modeling (MLM) was performed with random-effects for EDs, to evaluate associations between occupancy rate and turnaround time.

Results

Between January 2010 and December 2010, 163,659 patients transported to 28 EDs were enrolled. The median occupancy rate was 0.42 (range: 0.10-1.94; interquartile range (IQR): 0.20-0.76). Overcrowded EDs were more likely to have older patients, those with normal mentality, and non-trauma patients. Overcrowded EDs were more likely to have longer turnaround intervals and traveling distances. The MLM analysis showed that an increase of 1% in occupancy rate was associated with 0.02-minute decrease in turnaround interval (95% CI: 0.01 to 0.03). In subgroup analyses limited to EDs with occupancy rates over 100%, we also observed a 0.03 minute decrease in turnaround interval per 1% increase in occupancy rate (95% CI: 0.01 to 0.05).

Conclusions

In this study, we found wide variation in emergency department crowding in a metropolitan Korean city. Our data indicate that ED overcrowding is negatively associated with turnaround interval with very small practical significance.

Project description:BACKGROUND:Emergency department overcrowding negatively impacts critically ill patients and could lead to the occurrence of cardiac arrest. However, the association between emergency department crowding and the occurrence of in-hospital cardiac arrest has not been thoroughly investigated. This study aimed to evaluate the correlation between emergency department occupancy rates and the incidence of in-hospital cardiac arrest. METHODS:A single-center, observational, registry-based cohort study was performed including all consecutive adult, non-traumatic in-hospital cardiac arrest patients between January 2014 and June 2017. We used emergency department occupancy rates as a crowding index at the time of presentation of cardiac arrest and at the time of maximum crowding, and the average crowding rate for the duration of emergency department stay for each patient. To calculate incidence rate, we divided the number of arrest cases for each emergency department occupancy period by accumulated time. The primary outcome is the association between the incidence of in-hospital cardiac arrest and emergency department occupancy rates. RESULTS:During the study period, 629 adult, non-traumatic cardiac arrest patients were enrolled in our registry. Among these, 187 patients experienced in-hospital cardiac arrest. Overall survival discharge rate was 24.6%, and 20.3% of patients showed favorable neurologic outcomes at discharge. Emergency department occupancy rates were positively correlated with in-hospital cardiac arrest occurrence. Moreover, maximum emergency department occupancy in the critical zone had the strongest positive correlation with in-hospital cardiac arrest occurrence (Spearman rank correlation ??=?1.0, P?<?.01). Meanwhile, occupancy rates were not associated with the ED mortality. CONCLUSION:Maximum emergency department occupancy was strongly associated with in-hospital cardiac arrest occurrence. Adequate monitoring and managing the maximum occupancy rate would be important to reduce unexpected cardiac arrest.

Project description:Clinical handovers of patient care among healthcare professionals is vulnerable to the loss of important clinical information. A verbal report is typically provided by paramedics and documented by emergency department (ED) triage nurses. Paramedics subsequently complete a patient care report which is submitted electronically. This emergency medical system (EMS) patient care report often contains details of paramedic assessment and management that is not all captured in the nursing triage note. EMS patient care reports are often unavailable for review by emergency physicians and nurses. Two processes occur in the distribution of EMS patient care reports. The first is an external process to the ED that is influenced by the prehospital emergency medical system and results in the report being faxed to the ED. The second process is internal to the ED that requires clerical staff to distribute the fax report to accompany patient charts. A baseline audit measured the percentage of EMS patient care reports that were available to emergency physicians at the time of initial patient assessments and showed a wide variation in the availability of EMS reports. Also measured were the time intervals from patient transfer from EMS to ED stretcher until the EMS report was received by fax (external process measure) and the time from receiving the EMS fax report until distribution to patient chart (internal process measure). These baseline measures showed a wide variation in the time it takes to receive the EMS reports by fax and to distribute reports. Improvement strategies consisted of: 1. Educating ED clerical staff about the importance of EMS reports 2. Implementing a new process to minimize ED clerical staff handling of EMS reports for nonactive ED patients 3. Elimination of the automatic retrieval of old hospital charts and their distribution for ED patients 4. Introduction of an electronic dashboard for patients arriving by ambulance to facilitate more efficient distribution of EMS reports. Implementation of change strategies did not result in a significant improvement in the percentage of EMS reports available to emergency physicians at the time of initial patient assessment. However, tracking both external and internal processes that influence EMS report availability showed the internal process time from fax report receipt to distribution significantly improved. This improvement reflected the change strategies that were all directed at improving the internal process. EMS patient care reports are more efficiently processed and distributed in the ED due to change strategies implemented that targeted the ED's internal process of EMS report distribution. The external process responsible for transmitting EMS reports to the ED is the limiting factor that prevents consistent timely access of EMS reports by emergency physicians and will require dedicated improvement strategies.

Project description:ObjectivesTo conduct a scoping review to identify and summarise the existing literature on interventions involving primary healthcare professionals to manage emergency department (ED) overcrowding.DesignA scoping review.Data sourcesA comprehensive database search of Medline (Ovid), EMBASE (Ovid), Cochrane Library (Wiley) and CINAHL (EBSCO) databases was conducted (inception until January 2020) using peer-reviewed search strategies, complemented by a search of grey literature sources.Eligibility criteriaInterventions and strategies involving primary healthcare professionals (PHCPs: general practitioners (GPs), nurse practitioners (NPs) or nurses with expanded role) to manage ED overcrowding.MethodsWe engaged and collaborated, with 13 patient partners during the design and conduct stages of this review. We conducted this review using the JBI guidelines. Two reviewers independently selected studies and extracted data. We conducted descriptive analysis of the included studies (frequencies and percentages).ResultsFrom 23 947 records identified, we included 268 studies published between 1981 and 2020. The majority (58%) of studies were conducted in North America and were predominantly cohort studies (42%). The reported interventions were either 'within ED' (48%) interventions (eg, PHCP-led ED triage or fast track) or 'outside ED' interventions (52%) (eg, after-hours GP clinic and GP cooperatives). PHCPs involved in the interventions were: GP (32%), NP (26%), nurses with expanded role (16%) and combinations of the PHCPs (42%). The 'within ED' and 'outside ED' interventions reported outcomes on patient flow and ED utilisation, respectively.ConclusionsWe identified many interventions involving PHCPs that predominantly reported a positive impact on ED utilisation/patient flow metrics. Future research needs to focus on conducting well-designed randomized controlled trials (RCTs) and systematic reviews to evaluate the effectiveness of specific interventions involving PHCPs to critically appraise and summarise evidence on this topic.
