ABSTRACT The purpose of this paper was to review and analyze all the literature concerning ED patient throughput. The secondary goal was to determine if certain factors would significantly alter patients' ED throughput.
A MEDLINE search was performed from 1966 to 2007 using the terms "turnaround," "emergency departments," "emergency medicine," "efficiency," "throughput," "overcrowding" and "crowding." Studies were graded using a scale of one to four based on the ACEP paper quality criteria. Inclusion criteria were English language and at least a level four or better on the quality scale. An analysis of successful procedures and techniques was performed.
Literature search using the key terms found 29 articles on turnaround times, 129 on ED efficiency, 3 on throughput, 64 on overcrowding and 52 on crowding. Twenty-six articles were found to meet the inclusion criteria. There were three level I studies, thirteen level II studies, five level III studies and five level IV studies. The studies were categorized into five areas: determinants (7), laboratories processes (4), triage process (3), academic responsibilities (2), and techniques (10). Few papers used the same techniques or process to examine or reduce patient throughput precluding a meta-analysis.
An analysis of the literature was difficult because of varying study methodologies and less than ideal quality. EDs with combinations of low inpatient census, in-room registration, point of care testing and an urgent care area demonstrated increased patient throughput.

    ABSTRACT: The strongest evidence for effectiveness of screening, brief intervention, and referral to treatment (SBIRT) programs is in primary care settings. Emergency department (ED) studies have shown mixed results. Implementation of SBIRT into ED settings is complicated by the type of patients seen and the fast-paced, high-throughput nature of the ED environment that makes it difficult to reach patients flagged for SBIRT services. This study uses data from an ED-based SBIRT program to examine the relationship between screen-positive rate, ED patient flow, and SBIRT service delivery. Data for the study (N = 67137) were derived from weekly reports extracted directly from one hospital's electronic health record. Measures included time and day of patient entry, drug/alcohol screen result (positive or negative), and whether the patient was reached by SBIRT specialists. Factorial analysis of variance compared variations in screen-positive rates by day and time and the percentage of patients reached by SBIRT specialists during these periods. Overall, 56% of screen-positive patients received SBIRT services. Only 5% of patients offered SBIRT services refused. Day and time of entry had a significant interaction effect on the reached rate (F12,14166 =3.48, P < .001). Although patient volume was lowest between 11 pm and 7 am, screen-positive rates were highest during this period, particularly on weekends; and patients were least likely to be reached during these periods. When implementing an ED-based SBIRT program, thoughtful consideration should be given to patient flow and staffing to maximize program impact and increase the likelihood of sustainability.

    ABSTRACT: Objective: This study aimed to determine whether the implementation of point-of-care (POC) group A strep testing in a pediatric emergency department (ED) by nursing staff would lead to an increase in patient throughput. Methods: Patient throughput will be measured by average length of stay (LOS) in the ED and comparison of LOS of overall ED patients in ratio comparison to those on whom POC testing (POCT) is performed. In addition, those with positive POCT results will be compared to those with negative POCT results to determine the overall benefit in throughput for a positive test result. Results: Length of stay data of patients in the ED were collected beginning in the fourth quarter of 2006 through the fourth quarter of 2009. Conclusions: Implementation of POCT by nursing and nursing aid staff was shown to provide a statistically significant drop in LOS of patients who had group A strep testing performed on them, discharging them 25 to 30 minutes faster than other patients on average.

    ABSTRACT: BACKGROUND: As part of a quality improvement initiative to reduce Emergency Department (ED) length of stay (LOS) for surgical consult patients, we e-mailed performance metrics to key stakeholders on a daily basis. ED and Surgery leadership used these daily metrics to identify and remedy contributing factors for increased ED LOS in patients who received surgical consults. OBJECTIVE: To evaluate whether a quality improvement process driven by a daily performance metric e-mail would be associated with a change in ED LOS for surgical consult patients. METHODS: Prospective before-after study looking at ED LOS for surgical consult patients after an e-mail intervention at a tertiary academic teaching hospital. All consecutive adult ED patients between July 1, 2010 and October 1, 2010 who received a general surgical consult were enrolled. The primary outcome measure was ED LOS, and secondary outcome measure was time to consultation. RESULTS: There were 916 patients who had surgical consults placed during the study period; 459 patients presented before the intervention and 457 patients presented after the intervention. The median LOS decreased 54 min, from 463 min (interquartile range [IQR] 326-617) before the intervention to 409 min (IQR 294.5-528.5) after the intervention (p < 0.001). Time to consultation decreased 25 min, from a median of 160 min (IQR 87-265) to 135 min (IQR 70-239.5) (p = 0.002). There was no difference in age, severity, number of consults, or disposition. There was also no difference in median LOS for other consultation services or in previous years during the same time period. CONCLUSIONS: ED LOS and time to consultation were decreased for surgical consult patients after initiation of daily performance metric e-mails.
