Abstract
STUDY OBJECTIVE The emergency department (ED) poses unique challenges and risks to persons living with dementia. A longer ED length of stay is associated with the risk of death, delirium, and medication errors. We sought to determine whether ED length of stay differed by dementia status and trends in ED length of stay for persons living with dementia from 2014 to 2018 and whether persons living with dementia were at a higher risk for prolonged ED length of stay (defined as a length of stay > 90th percentile). METHODS In this observational study, we used data from the Healthcare Cost and Utilization Project State Emergency Department Database from Massachusetts, Arkansas, Arizona, and Florida. We included ED visits resulting in discharge for adults aged ≥65 years from 2014 to 2018. We used inverse probability weighting to create comparable groups of visits on the basis of dementia status. We used generalized linear models to estimate the mean difference in ED length of stay on the basis of dementia status and logistic regression to determine the odds of prolonged ED length of stay. RESULTS We included 1,039,497 ED visits (mean age: 83.5 years; 64% women; 78% White, 12% Hispanic). Compared with visits by persons without dementia, ED length of stay was 3.1 hours longer (95% confidence interval [CI] 3.0 to 3.3 hours) for persons living with dementia. Among the visits resulting in transfer, ED length of stay was on average 4.1 hours longer (95% CI 3.6 to 4.5 hours) for persons living with dementia. Visits by persons living with dementia were more likely to have a prolonged length of stay (risk difference 4.1%, 95% CI 3.9 to 4.4). CONCLUSION ED visits were more than 3 hours longer for persons living with versus without dementia. Initiatives focused on optimizing ED care for persons living with dementia are needed.

From symptom onset to ED departure: understanding the acute care chain for patients with undifferentiated complaints: a prospective observational study. Int J Emerg Med 2024; 17:55. [PMID: 38622511 PMCID: PMC11020825 DOI: 10.1186/s12245-024-00629-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 03/28/2024] [Indexed: 04/17/2024] Open
Abstract
BACKGROUND For most acute conditions, the phase prior to emergency department (ED) arrival is largely unexplored. However, this prehospital phase has proven an important part of the acute care chain (ACC) for specific time-sensitive conditions, such as stroke and myocardial infarction. For patients with undifferentiated complaints, exploration of the prehospital phase of the ACC may also offer a window of opportunity for improvement of care. This study aims to explore the ACC of ED patients with undifferentiated complaints, with specific emphasis on time in ACC and patient experience. METHODS This Dutch prospective observational study, included all adult (≥ 18 years) ED patients with undifferentiated complaints over a 4-week period. We investigated the patients' journey through the ACC, focusing on time in ACC and patient experience. Additionally, a multivariable linear regression analysis was employed to identify factors independently associated with time in ACC. RESULTS Among the 286 ED patients with undifferentiated complaints, the median symptom duration prior to ED visit was 6 days (IQR 2-10), during which 58.6% of patients had contact with a healthcare provider before referral. General Practitioners (GPs) referred 80.4% of the patients, with the predominant patient journey (51.7%) involving GP referral followed by self-transportation to the ED. The median time in ACC was 5.5 (IQR 4.0-8.4) hours of which 40% was spent before the ED visit. GP referral and referral to pulmonology were associated with a longer time in ACC, while referral during evenings was associated with a shorter time in ACC. Patients scored both quality and duration of the provided care an 8/10. CONCLUSION Dutch ED patients with undifferentiated complaints consulted a healthcare provider in over half of the cases before their ED visit. The median time in ACC is 5.5 h of which 40% is spent in the prehospital phase. Those referred by a GP and to pulmonology had a longer, and those in the evening a shorter time in ACC. The acute care journey starts hours before patients arrive at the ED and 6 days of complaints precede this journey. This timeframe could serve as a window of opportunity to optimise care.

Abstract
Background This study aimed to explore the process, clinical, and patient-reported outcomes of older adults who received an interdisciplinary Comprehensive Geriatric Assessment (CGA) in the emergency department (ED) over a six-month period after their initial ED attendance. Patients and Methods A prospective cohort study recruited older adults aged ≥65 years who presented to the ED of a university teaching hospital in Ireland. Baseline assessment data comprising a battery of demographic variables and validated indices were obtained at the index ED attendance. Telephone interviews were completed with participants at 30- and 180-day follow-up. The primary outcome was incidence of hospital admission following the index ED attendance. Secondary outcomes included participant satisfaction, incidence of functional decline, health-related quality of life, incidence of unscheduled ED re-attendance(s), hospital (re)admission(s), nursing home admission, and death. Results A total of 133 participants (mean age 82.43 years, standard deviation = 6.89 years; 71.4% female) were recruited; 21.8% of the cohort were admitted to hospital following the index ED attendance with a significant decline in function reported at hospital discharge (Z = 2.97, p = 0.003). Incidence of 30- and 180-day unscheduled ED re-attendance was 10.5% and 24.8%, respectively. The outcome at the index ED attendance was a significant predictor of adverse outcomes whereby those who were discharged home had significantly lower odds of multiple adverse process outcomes at 30- and 180-day follow-up, and significantly higher function and health-related quality of life at 30-day follow-up. Conclusion While this study was observational in nature, findings suggest CGA in the ED may improve outcomes by mitigating against the adverse effects of potentially avoidable hospital admissions and focusing on a longitudinal approach to healthcare delivery at the primary-secondary care interface. Future research should be underpinned by an experimental study design to address key limitations in this study.

Abstract
BACKGROUND Older adults frequently attend the Emergency Department (ED) with poorly defined symptoms, often called nonspecific complaints (NSC). NSC such as 'weakness' and 'not feeling well', often lead to an extensive differential diagnosis. Patients with NSC experience a prolonged length of stay at the ED and are prone to adverse outcomes. Currently, a care pathway for patients with NSC does not exist. A special structured care pathway for patients with NSC was designed to improve the efficiency and quality of care at the ED. METHOD A multicenter parallel cohort study, organized in different hospitals in the Noord-Brabant area, the Netherlands, in which general practitioners (GP), elderly care physicians (ECP), Emergency Physicians (EP), geriatricians and internists will collaborate. Patients ≥ 70 years presenting with NSC and in need of ED admission as indicated by their own GP or ECP are eligible for inclusion. Before implementation each hospital will retrospectively include their own control-group. After implementation, patients will prospectively be included. The care-pathway exists of risk stratification by the APOP-screener, in-depth history taking, i.e. limited comprehensive geriatric assessment (CGA) and a standard set of diagnostics, and a dedicated ED-nurse (if possible) present to ensure the care-pathway is followed. The primary outcome is length of stay at the ED (LOS-ED) and perceived quality of care. Secondary outcomes are hospital length of stay, revisits, readmissions and mortality at 30- and 90-day follow-up. DISCUSSION This study proposes a structured care pathway for older patients presenting at the ED with NSCs and considering effectiveness and perceived quality this may improve acute care for these patients.

Abstract
BACKGROUND Abdominal pain is one of the most frequent causes for emergency department (ED) visits. The quality of care and outcomes are determined by time-dependent interventions with barriers to implementation at crowded EDs. OBJECTIVES The study aimed to analyze three prominent quality indicators (QI) including pain assessment (QI1), analgesia in patients reporting severe pain (QI2), and ED length of stay (LOS) (QI3) in adult patients requiring immediate or urgent care due to acute abdominal pain. We aimed to characterize current practice regarding pain management, and we hypothesized that extended ED LOS (≥ 360 min) is associated with poor outcomes in this cohort of ED referrals. METHODS This is a retrospective cohort study enrolling all patients with acute abdominal pain as the main cause of ED presentation, triage category red, orange, or yellow, and age ≥ 30 years during two months period. Univariate and multivariable analyses were deployed to determine independent risk factors for QIs performance. For QI1 and QI2, compliance with the QIs were analyzed, while 30-day mortality was set as primary outcome for QI3. RESULTS Overall, 965 patients were analyzed including 501 (52%) males with a mean age of 61.8 years. Seventeen percent (167/965) of the patients had immediate or very urgent triage category. Age ≥ 65 years, and red and orange triage categories were risk factors for non-compliance with pain assessment. Seventy four per cent of patients with severe pain (numeric rating scale ≥ 7) received analgesia during the ED visit, in median within 64 min (IQR 35-105 min). Age ≥ 65 years and need for surgical consultation were risk factors for prolonged ED stay. After adjustment to age, gender and triage category, ED LOS ≥ 360 min proved to be independent risk factor for 30-day mortality (HR 1.89, 95% CI 1.71-3.40, p = 0.034). CONCLUSION Our investigation identified that non-compliance with pain assessment, analgesia and ED length of stay among patients presenting with abdominal pain to ED results in poor quality of care and detrimental outcomes. Our data support enhanced quality-assessment initiatives for this subset of ED patients.

Prolonged length of stay and its associated factors at adult emergency department in amhara region comprehensive specialized hospitals, northwest Ethiopia. BMC Emerg Med 2023; 23:34. [PMID: 36977998 PMCID: PMC10053138 DOI: 10.1186/s12873-023-00804-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 03/13/2023] [Indexed: 03/30/2023] Open
Abstract
Abstract
Background
Prolonged length of stay at the emergency department interferes with the main goal of emergency care and results in adverse patient outcomes like nosocomial infection, dissatisfaction, morbidity, and mortality. Despite this, little is known about the length of stay and the factors that influence it in Ethiopia’s emergency department.
Methods
An institution-based cross-sectional study was conducted on 495 patients admitted at Amhara region comprehensive specialized hospitals emergency department from May 14 to June 15/2022. A systematic random sampling was employed to select study participants. A pretested structured interview-based questionnaire was used to collect data by using Kobo toolbox software. SPSS version 25 was used for data analysis. Bi-variable logistic regression analysis was carried out to select variables with P-value < 0.25. The significance of association was interpreted using an Adjusted Odds Ratio with a 95% confidence interval. Variables with P-value < 0.05 in the multivariable logistic regression analysis were inferred to be significantly associated with length of stay.
Result
Out of 512 enrolled participants, 495 were participated with a response rate of 96.7%. The prevalence of prolonged length of stay in the adult emergency department was 46.5% (95%CI: 42.1, 51.1). Lack of insurance (AOR: 2.11; 95% CI: 1.22, 3.65), non-communicative presentation (AOR: 1.98; 95% CI: 1.07, 3.68), delayed consultation (AOR: 9.5; 95% CI: 5.00, 18.03), overcrowding (AOR: 4.98; 95% CI: 2.13, 11.68), and shift change experience (AOR: 3.67; 95% CI: 1.30, 10.37) were significantly associated with prolonged length of stay.
Conclusion
The result of this study is found to be high based on Ethiopian target emergency department patient length of stay. Lack of insurance, presentation without communication, delayed consultation, overcrowding, and shift change experience were significant factors for prolonged emergency department length of stay. Therefore, interventions like expansion of organizational setup are needed to decrease the length of stay to an acceptable level.

Abstract
Background: Due to the increase in life expectancy, both the general population and the population of patients of emergency departments (ED) are getting older. An understanding of differences, workload and resource requirements may be helpful in improving patient care. The main goal of this study was to evaluate the reasons for geriatric admissions in the ED, identify typical medical problems and assess the number of resources in order to provide more effective management. Methods: We examined 35,720 elderly patients' ED visits over the course of 3 years. The data collected included age, sex, timing and length of stay (LOS), use of various resources, endpoint (admission, discharge or death) and ICD-10 diagnoses. Results: The median age was 73 years [66-81], with more females (54.86%). There were 57.66% elderly (G1), 36.44% senile (G2) and 5.89% long-liver (G3) patients. There were more females in the older groups. The total admission rate was 37.89% (34.19% for G1, 42.21% for G2 and 47.33% for G3). The average length of the patient's stay was 150 min [81-245] (G3 180 min [108-277], G2 (162 min [92-261]) and G1 139 min [71-230]). Heart failure, atrial fibrillation and hip fracture were the most common diagnoses. Nonspecific diagnoses were common in all groups. Conclusion: The vast majority of geriatric patients required considerable resources. With increasing ages, the number of women, LOS and number of admissions increased.

Abstract
Objectives We set out to determine the accuracy of the interRAI Emergency Department (ED) Screener in predicting the need for detailed geriatric assessment in the ED. Our secondary objective was to determine the discriminative ability of the interRAI ED Screener for predicting the odds of discharge home and extended ED length of stay (>24 hours). Methods We conducted a multiprovince prospective cohort study in Canada. The need for detailed geriatric assessment was determined using the interRAI ED Screener and the interRAI ED Contact Assessment as the reference standard. A score of ≥5 was used to classify high-risk patients. Assessments were conducted by emergency and research nurses. We calculated the sensitivity, positive predictive value, and false discovery rate of the interRAI ED Screener. We employed logistic regression to predict ED outcomes while adjusting for age, sex, academic status, and the province of care. Results A total of 5629 older ED patients across 11 ED sites were evaluated using the interRAI ED Screener and 1061 were evaluated with the interRAI ED Contact Assessment. Approximately one-third of patients were discharged home or experienced an extended ED length of stay. The interRAI ED Screener had a sensitivity of 93%, a positive predictive value of 82%, and a false discovery rate of 18%. The interRAI ED Screener predicted discharge home and extended ED length of stay with fair accuracy. Conclusion The interRAI ED Screener is able to accurately and rapidly identify individuals with medical complexity. The interRAI ED Screener predicts patient-important health outcomes in older ED patients, highlighting its value for vulnerability screening.

Shorter laboratory turnaround time is associated with shorter emergency department length of stay: a retrospective cohort study. BMC Emerg Med 2022; 22:207. [PMID: 36544114 PMCID: PMC9768765 DOI: 10.1186/s12873-022-00763-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 12/03/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND A longer emergency department length of stay (EDLOS) is associated with poor outcomes. Shortening EDLOS is difficult, due to its multifactorial nature. A potential way to improve EDLOS is through shorter turnaround times for diagnostic testing. This study aimed to investigate whether a shorter laboratory turnaround time (TAT) and time to testing (TTT) were associated with a shorter EDLOS. METHODS A retrospective cohort study was performed, including all visits to the emergency department (ED) of an academic teaching hospital from 2017 to 2020 during which a standardized panel of laboratory tests had been ordered. TTT was calculated as the time from arrival in the ED to the ordering of laboratory testing. TAT was calculated as the time from test ordering to the reporting of the results, and was divided into a clinical and a laboratory stage. The outcome was EDLOS in minutes. The effect of TTT and TAT on EDLOS was estimated through a linear regression model. RESULTS In total, 23,718 ED visits were included in the analysis. Median EDLOS was 199.0 minutes (interquartile range [IQR] 146.0-268.0). Median TTT was 7.0 minutes (IQR 2.0-12.0) and median TAT was 51.1 minutes (IQR 41.1-65.0). Both TTT and TAT were positively associated with EDLOS. The laboratory stage comprised a median of 69% (IQR 59-78%) of total TAT. CONCLUSION Longer TTT and TAT are independently associated with longer EDLOS. As the laboratory stage predominantly determines TAT, it provides a promising target for interventions to reduce EDLOS and ED crowding.

Patient and hospital characteristics predict prolonged emergency department length of stay and in-hospital mortality: a nationwide analysis in Korea. BMC Emerg Med 2022; 22:183. [PMID: 36411433 PMCID: PMC9677700 DOI: 10.1186/s12873-022-00745-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 11/04/2022] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Prolonged emergency department length of stay (EDLOS) in critically ill patients leads to increased mortality. This nationwide study investigated patient and hospital characteristics associated with prolonged EDLOS and in-hospital mortality in adult patients admitted from the emergency department (ED) to the intensive care unit (ICU). METHODS We conducted a retrospective cohort study using data from the National Emergency Department Information System. Prolonged EDLOS was defined as an EDLOS of ≥ 6 h. We constructed multivariate logistic regression models of patient and hospital variables as predictors of prolonged EDLOS and in-hospital mortality. RESULTS Between 2016 and 2019, 657,622 adult patients were admitted to the ICU from the ED, representing 2.4% of all ED presentations. The median EDLOS of the overall study population was 3.3 h (interquartile range, 1.9-6.1 h) and 25.3% of patients had a prolonged EDLOS. Patient characteristics associated with prolonged EDLOS included night-time ED presentation and Charlson comorbidity index (CCI) score of 1 or higher. Hospital characteristics associated with prolonged EDLOS included a greater number of staffed beds and a higher ED level. Prolonged EDLOS was associated with in-hospital mortality after adjustment for selected confounders (adjusted odds ratio: 1.18, 95% confidence interval: 1.16-1.20). Patient characteristics associated with in-hospital mortality included age ≥ 65 years, transferred-in, artificially ventilated in the ED, assignment of initial triage to more urgency, and CCI score of 1 or higher. Hospital characteristics associated with in-hospital mortality included a lesser number of staffed beds and a lower ED level. CONCLUSIONS In this nationwide study, 25.3% of adult patients admitted to the ICU from the ED had a prolonged EDLOS, which in turn was significantly associated with an increased in-hospital mortality risk. Hospital characteristics, including the number of staffed beds and the ED level, were associated with prolonged EDLOS and in-hospital mortality.

Abstract
Introduction In-patient delay is associated with increased mortality in patients with alimentary tract perforations. Access to surgical care is a glaring health issue in low-middle income countries (LMICs), where patient presentation is also delayed for a myriad of reasons, which can be broadly categorized as social/cultural, financial, and structural in their nature. The impact these delays have on surgical outcomes in low-middle income countries is not known. Methods A retrospective cohort study of patients who underwent emergency laparotomy for alimentary tract perforation from July 2015 to June 2018 was conducted at a tertiary care hospital in Karachi, Pakistan. Time was recorded in two variables: symptom onset to emergency room presentation (ERT) and emergency room to operation room time (ORT). Results Overall, 80 patients were included in the study. The 12 (15%) patients who expired were significantly older (57 ± 17.7 years of age), had a higher Charlson Comorbidity Index and had longer ORT [median ORT in hours-discharged vs expired: 8.2 (IQR 5-15) vs 16 (IQR 12-28) p=0.02]. ERT was also longer but lacked statistical significance [median ERT in hours-discharged vs expired: 24 (IQR 22-72) vs 48 (IQR 24-120) p=0.19]. Multivariable logistic regression analysis revealed ORT to be significantly associated with mortality [odds ratio (OR): 1.02, 95% confidence interval (CI): 1.003-1.041; p=0.02]. Adjusted Cox regression analysis showed that each hour of ORT increased the risk of mortality by 1.5% [hazard ratio (HR) 1.015, 95% CI 1.001-1.030]. Conclusion Inpatient delays increased the risk of mortality for patients undergoing emergency laparotomy for alimentary tract perforation. Larger sample sizes and prospective studies are needed to better understand this relationship and the impact pre-hospital delays have on outcomes.

Abstract
Emergency Department (ED) Length Of Stay (ED-LOS) is associated with quality of care, patient safety and treatment outcome. The aim of this study is to identify factors associated with ED-LOS of internal medicine patients and provide recommendations to shorten ED-LOS. A retrospective cohort study was conducted in a single center in the Netherlands. Anonymised data of 7,380 ED attendances from January 2016 to January 2018 were analyzed. Data included time of ED arrival and departure, sex, age, source of referral, triage category, first or consecutive visit and number of radiological examinations. Univariate analyses were used. Mean ED-LOS was 220 minutes. Factors which significantly prolonged ED-LOS were older age, source of referral, triage category, need for admission, first visit, number of radiological examinations, presentation in winter or spring and time of arrival (day and evening). Several patient and circumstantial factors are associated with ED-LOS. To shorten ED-LOS, we recommend to anticipate need for admission for older patients who arrive by ambulance and to create time slots in the radiology program and to restructure the morning report.

Abstract
OBJECTIVE Several studies have previously reported that a prolonged emergency department length of stay (EDLOS) is associated with poor outcomes in critically ill patients. This study was performed to investigate the relationship between the EDLOS and the neurologic outcome at 28 days in out-of-hospital cardiac arrest (OHCA) patients. METHODS We conducted a retrospective analysis of prospectively collected data from OHCA patients who achieved the return of spontaneous circulation (ROSC) in the EDs of three urban tertiary teaching hospitals from December 2013 to October 2020. Patients were divided into four groups according to the EDLOS, according to the quartile distribution: EDLOS <107 min, EDLOS 107-176 min, EDLOS 176-275 min, and EDLOS ≥275 min. Comparisons of outcomes among the groups and multivariable logistic regression analysis were performed. RESULTS A total of 807 patients were included in the analysis. The proportions of patients with a good neurologic outcome at 28 days in the groups with EDLOS <107 min, EDLOS 107-176 min, EDLOS 176-275 min, and EDLOS ≥275 min were 37.0%, 29.8%, 26.9, and 20.4%, respectively (p < 0.001). In the multivariable analysis, the odds ratios for a poor neurologic outcome at 28 days in the groups with EDLOS 107-176 min, EDLOS 176-275 min, and EDLOS ≥275 min compared with the group with EDLOS <107 min were 1.19 (95% CI, 0.67-2.13), 1.73 (95% CI, 0.95-3.21), and 1.91 (95% CI, 1.03-3.57), respectively. CONCLUSIONS An EDLOS longer than 275 min after the ROSC was independently associated with a poor neurologic outcome at 28 days.

Abstract
BACKGROUND Dedicated geriatric models of care are becoming more prevalent due to the complexity of, and increase in, acute healthcare presentations for older patients. For older people, a long stay in the emergency department (ED) may reflect the complexity of their presentation, or deficiencies in systems that manage these complexities. AIMS To identify predictors of a long ED length of stay (LLoS) for patients ≥65 years old. METHODS Linked hospital information systems data from a large, public Australian ED were analysed in this retrospective cohort study. LLoS was defined as the 75th percentile (617 min). Multivariate regression identified LLoS predictors for admissions and discharges separately. RESULTS Of 16 791 ED presentations made by older people, 4192 experienced a LLoS; 55% were admitted. Increasing age was associated with an increasing ED LoS. Factors most predictive of LLoS for both admitted and discharged patients included: investigations (both pathology and imaging), less urgent Australasian triage scale categories and after-hours arrival. Ambulance arrival did not increase the risk of a LLoS for patients eventually admitted, but conferred nearly a twofold increased risk for a LLoS for discharged older persons (adjusted odds ratios = 1.9; 95% confidence interval 1.5-2.4). CONCLUSIONS This study assists clinicians and decision-makers to identify reasons why older persons have a LLoS, whether admitted or discharged. Interventions to streamline care for older patients arriving after-hours and who require imaging and pathology are required. LoS targets should consider age distribution. The use of ED LoS as a quality of care indicator should be assessed for admissions and discharges, separately.

Abstract
The aim of the study was to analyze and compare consultation lengths in Emergency Medical Service (EMS) Belgrade ambulatory clinic which relates to patient age, gender, existing diagnoses and prescribed treatment (therapy or referral to another healthcare institution). We analyzed the data from the electronic database on consultation lengths from one EMS Belgrade Ambulatory Clinic. For patients who were further referred to another healthcare institution transfer, the waiting time was included in the total consultation time. We used the statistical package SPSS 11.0 for Windows for the statistical processing. Statistical significance was defined for the level of p < 0.05. The average consultation time was 21.07 ± 13.44 minutes. Usually, it lasted between 10 to 20 minutes. Consultations lasted longer in female patients (21.68 minutes), patients over 65 years of age (24.65 minutes), in patients with multiple diagnoses (26.1 and 27.28 minutes), as well as in patients where therapy was prescribed and administered in the ambulatory clinic (25.72 minutes), or in patients referred to other healthcare institutions. Statistically, the differences were highly significant (p < 0.01). When considering patients' diagnoses, longest consultations were in patients diagnosed with infectious diseases (average 30.88 minutes), followed by patients diagnosed with diseases of the circulatory system (27.86 minutes) and patients with diseases of the respiratory system (21.56 minutes). The differences were statistically significant (p < 0.01). Patients' age, gender, disease diagnosis and administered therapy affect the consultations time. Depending on the diagnosis, consultations last longer for infectious, cardiovascular and respiratory diseases.

Abstract
Objective: Return visit to emergency department (ED) is a common phenomenon and has been a clinical indicator of quality of care in ED. Most of previous articles focused on the characteristics of the patients returning within 72 h after ED discharge, while those on subsequent admission are numbered. This study's purpose is to identify risk factors for admission among 72-h return visit in the ED adult population. Materials and Methods: This retrospective cohort study was conducted at a medical center in Eastern Taiwan. The study period was from January 1, 2013, to December 31, 2013. We excluded patients who left against medical advice or without being seen, who was admitted or transferred at the index ED visit, whose medical records were incomplete, and whose age was below 18 years old. Significant variables were selected based on univariate analysis and later entered into multivariate logistic regression analysis to identify risk factors for 72-h return admission. Results: We identified 1575 eligible visits, and there were 1,119 visits entering into the final analysis. Male gender (odds ratio [OR] = 1.44), ambulance-transport at return visit (OR = 3.68), senior staff (OR = 1.52), work-up (OR = 3.03), and longer length of stay (LOS) were associated with higher risks of admission among ED 72-h return visits. Age, comorbidity, mode of transport at index visit, consultation, triage, type of illness, outpatient department visit between ED visits, and interval between index and return visits were not significantly associated with return admission. Conclusion: Gender, mode of transportation, staff experience, check-up, and LOS are associated with ED return admission.

Abstract
Background Providing high quality care is important and has gained more attention since the introduction of value-based healthcare. Value should be measured by outcomes achieved, relevant for patients. Patient-centeredness is one domain for quality improvement determined by the Institute of Medicine, aiming to deliver care responsive to the patient. The development and implementation of patient reported outcome- and experience measures can be used for this goal. Recently, we developed the Patient Reported Measure (PRM)-acute care, based on five relevant domains to evaluate and improve the quality of care in the Emergency Department (ED). Objective To validate the PRM-acute care, in order to evaluate and improve patient-centered care in the ED. Methods We performed a prospective questionnaire-based study. Patients ≥18 years presenting for internal medicine in the ED were eligible. The validity of the PRM-acute care was evaluated according to the COSMIN-criteria. We performed hypotheses testing to evaluate construct validity. The perceived quality of care was evaluated by statistical analysis. Results Face- and content validity was evaluated based on previously performed research and deemed good. Construct validity was supported by demonstrated differences between subgroups; patients with severe symptoms had a higher perceived quality of care. The correlation between overall satisfaction and the total mean score of the PRM-acute care (r = 0,447, p = 0.01) was significant. Overall, patients reported a mean perceived quality of care of 4.67/6.0. Conclusion The PRM-acute care is a valid instrument to measure the perceived quality of care in an acute setting for internal medicine patients. Additionally, patients reported a good perceived quality of care in the ED with scores ranging from moderate to well for each of the relevant domains. Therefore, we believe that the PRM-acute care can be implemented in daily practice to evaluate the perceived quality of care and to improve the quality of acute care.

Abstract
INTRODUCTION Emergency Department (ED) Length of stay (LOS) has been associated with poor patient outcomes, which has led to the implementation of time targets designed to keep EDLOS below a specific limit. The cut-offs defining long EDLOS varies across settings and seem to be arbitrarily chosen. This study aimed to clarify the meaning of long EDLOS. METHODS A concept analysis using the Walker and Avant approach was conducted. It included a literature search aiming to identify all uses of the concept, resulting in a set of defining attributes and a way of measuring the concept empirically. RESULTS Long EDLOS was primarily used as proxy for other phenomena, e.g. boarding or crowding. The definitions had cut-offs ranging between 4 and 48 h. The attributes defining long EDLOS was waiting, a crowded ED environment and an inefficient organization. DISCUSSION Time targets are probably more suitable when directed towards and tailored for specific sub-groups of the ED population.

Abstract
INTRODUCTION Emergency department (ED) wait time is an important health system quality indicator. Prolonged consult to decision time (CTDT), the time it takes to reach a disposition decision after receiving a specialty consultation request, can contribute to increased overall length of stay in the ED. OBJECTIVE To identify delays in the consultation process for general internal medicine (GIM) and trial interventions to reduce CTDT. METHODS The study was conducted at a large tertiary teaching hospital with GIM inpatient wards at two campuses. Four interventions were trialed over sequential Plan-Do-Study-Act cycles: (1) process mapping, (2) resident education sessions, (3) audit and feedback of CTDT, and (4) adding a swing shift during peak consult volume. MEASUREMENTS The primary outcome measures were mean CTDT for patients admitted to GIM and the proportion of admitted patients with CTDT of less than 3 hours. RESULTS Mean CTDT decreased from 4.61 hours before intervention to 4.18 hours after intervention (p < .0001). The proportion of GIM patients with CTDT less than 3 hours increased from 25% to 33% (p < .0001). CONCLUSIONS The interventions trialed led to a sustained reduction in CTDT over a 12-month period and demonstrated the effectiveness of education in influencing physician performance.

Abstract
Emergency Care Networks (ECNs) were created as a response to the increased demand for emergency services and the ever-increasing waiting times experienced by patients in emergency rooms. In this sense, ECNs are called to provide a rapid diagnosis and early intervention so that poor patient outcomes, patient dissatisfaction, and cost overruns can be avoided. Nevertheless, ECNs, as nodal systems, are often inefficient due to the lack of coordination between emergency departments (EDs) and the presence of non-value added activities within each ED. This situation is even more complex in the public healthcare sector of low-income countries where emergency care is provided under constraint resources and limited innovation. Notwithstanding the tremendous efforts made by healthcare clusters and government agencies to tackle this problem, most of ECNs do not yet provide nimble and efficient care to patients. Additionally, little progress has been evidenced regarding the creation of methodological approaches that assist policymakers in solving this problem. In an attempt to address these shortcomings, this paper presents a three-phase methodology based on Discrete-event simulation, payment collateral models, and lean six sigma to support the design of in-time and economically sustainable ECNs. The proposed approach is validated in a public ECN consisting of 2 hospitals and 8 POCs (Point of Care). The results of this study evidenced that the average waiting time in an ECN can be substantially diminished by optimizing the cooperation flows between EDs.

Abstract
OBJECTIVES Patients presenting with a mental health disorder (MHD) wait longer in the ED compared to those presenting for other reasons, potentially placing vulnerable patients at further risk for deterioration. The present study identified factors associated with a long ED stay for patients with a MHD. METHODS Linked ambulance, emergency, pathology, imaging and admission data for an 18-month period were analysed for ED presentations diagnosed with an MHD ICD-10 at a large teaching hospital. Admissions and discharges were considered separately; a long ED stay was defined as the 90th percentile length of stay. Multivariable generalised linear models were built, identifying predictors of a long ED stay for presentations diagnosed with a MHD. RESULTS The sample comprised 1163 admissions and 2242 discharges. For admissions, significant predictors for long ED stay were investigations (pathology or imaging tests), a triage score of 1 or 2, arrival out-of-hours (18.00-05.59 hours) and arrival by ambulance. For discharges, significant predictors of a long ED stay were investigations (pathology or imaging tests), arrival out-of-hours, arrival by ambulance and increasing age. CONCLUSIONS Some factors predictive of a long ED stay for patients presenting to the ED and diagnosed with a MHD varied based on their disposition. For admissions, the most urgent presentations were likely to stay longest. Strategies to reduce ED stay for both admissions and discharges should consider addressing modifiable aspects, including the need for certain investigations, and non-modifiable aspects, including the need for further access to after-hours mental health services in hospital and in the community.

Abstract
BACKGROUND Measuring and understanding main determinants of length of stay (LOS) in emergency departments (EDs) is critical from an operations perspective, since LOS is one of the main performance indicators of ED operations. Therefore, this study analyzes both the main and interaction effects of four widely-used independent determinants of ED-LOS. METHODS The analysis was conducted using secondary data from an ED of a large urban hospital in Izmir, Turkey. Between-subject factorial analysis of variance (ANOVA) was used to test the main and interaction effects of the corresponding factors. P values <.05 were considered statistically significant. RESULTS While the main effect of gender was insignificant, age, mode of arrival, and clinical acuity had significant effects, whereby ED-LOS was significantly higher for the elderly, those arriving by ambulance, and clinically-categorized high-acuity patients. Additionally, there was an interaction between the age and clinical acuity in that, while ED-LOS increased with age for high acuity patients, the opposite trend occurred for low acuity patients. When ED-LOS was modeled using gender, age, and mode of arrival, there was a significant interaction between age and mode of arrival. However, this interaction was not significant when the model included age, mode of arrival, and clinical acuity. CONCLUSION Significant interactions exist between commonly used ED-LOS determinants. Therefore, interaction effects should be considered in analyzing and modelling ED-LOS.

Abstract
The most commonly used techniques for addressing each Emergency Department (ED) problem (overcrowding, prolonged waiting time, extended length of stay, excessive patient flow time, and high left-without-being-seen (LWBS) rates) were specified to provide healthcare managers and researchers with a useful framework for effectively solving these operational deficiencies. Finally, we identified the existing research tendencies and highlighted opportunities for future work. We implemented the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to undertake a review including scholarly articles published between April 1993 and October 2019. The selected papers were categorized considering the leading ED problems and publication year. Two hundred and three (203) papers distributed in 120 journals were found to meet the inclusion criteria. Furthermore, computer simulation and lean manufacturing were concluded to be the most prominent approaches for addressing the leading operational problems in EDs. In future interventions, ED administrators and researchers are widely advised to combine Operations Research (OR) methods, quality-based techniques, and data-driven approaches for upgrading the performance of EDs. On a different tack, more interventions are required for tackling overcrowding and high left-without-being-seen rates.

Blood sampling during nurse triage reduces patient length of stay in the emergency department: A propensity score-weighted, population-based study. Int Emerg Nurs 2020; 49:100826. [PMID: 32046951 DOI: 10.1016/j.ienj.2019.100826] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 11/12/2019] [Accepted: 11/29/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND Increases in patients' length of stay (LOS) in the emergency department (ED) have led to overcrowding. OBJECTIVES In this study, the implementation of blood sampling during triage in lower priority level patients was assessed as a possible means to reduce LOS. METHODS A retrospective study was performed from January 2018 to January 2019. Lower priority level patients who required blood sampling for further diagnosis were considered. Patients who underwent blood sampling during triage evaluation were compared with those who underwent blood sampling after a physician's initial evaluation. RESULTS During the study period, 15,596 patients were enrolled. LOS was shorter in patients who underwent triage blood sampling, presenting a median value of 154 min in comparison with the 172 min recorded in the control group (p < 0.001). Using a propensity score-matching to control the two groups' differences, LOS remained lower in the triage-sampling group (151 vs. 175 min; p < 0.001). In the adjusted multivariate model, triage blood sampling was found to be an independent factor for a decrease in the LOS, with standardized coefficient β = 0.857 (0.822-0.894; p < 0.001). CONCLUSIONS Performing blood sampling during nurse triage can decrease LOS in ED and also reduce ED permanence after a physician's initial evaluation.

Abstract
INTRODUCTION The aging of modern societies increases the general healthcare burden due to the growing demand for inpatient services, which lack adequate financing. MATERIAL AND METHODS Data concerning the costs of 312,250 hospitalizations at University Clinical Hospital in Wrocław, Poland in the years 2012-2015 were analyzed according to the age of the patients: below 65 years and 65 years and older, with subgroups (65-74, 75-84 and 85 years and older). RESULTS The mean length of stay (LOS) differed significantly for patients below 65 years and for patients 65 years old or older (3.5 vs. 4.7 person-days); over the 4 years covered by our data, these increased by 0.4 person-days, mostly among patients 85 years and older (by 0.7 person-days). The mean direct cost of hospitalization differed significantly for patients below 65 years and those 65 years or older (PLN 4,907.12 vs. PLN 6,357.15). The mean cost of laboratory tests and radiologic diagnostics was significantly higher among those in the 65+ group, and the difference had a rising trend. The differences between age groups in cost-related hospitalization characteristics and direct hospitalization costs that have been suggested by the medical literature have also been confirmed in Poland. CONCLUSIONS The mean hospitalization costs of patients aged 65 years and older in Poland are higher than for younger patients due to longer LOS and more complex and expensive treatment, especially laboratory and radiologic diagnostics, which is increasingly common in the oldest age groups. This demands an urgent systemic solution, especially in terms of adjusted financing of elderly patients' hospital treatment.

Abstract
It is not easy to ensure optimal prevention of hospital-acquired pressure ulcer (HAPU) in crowded emergency departments (EDs). We hypothesised that a prolonged ED length of stay (LOS) is associated with an increased risk of HAPU. This is a single-centre observational study. Prospectively collected HAPU surveillance data were analysed. Adult (aged ≥20 years) patients admitted through the ED from April 1, 2013 to December 31, 2016 were included. The primary outcome was the development of HAPU within a month. Covariates included demographics, comorbidities, conditions at triage, initial laboratory results, primary ED diagnosis, critical ED interventions, and ED dispositions. The association between ED LOS and HAPU was modelled using logistic and extended Cox regression. A total of 48 641 admissions were analysed. The crude odds ratio (OR) and hazard ratio (HR) for HAPU were increased to 1.44 (95% CI, 1.20-1.72) and 1.21 (95% CI, 1.02-1.45), respectively, in ED LOS ≥24 hours relative to ED LOS <6 hours. In multivariable logistic regression, ED LOS ≥12 and ≥24 hours were associated with higher risk of HAPU, with ORs of 1.30 (95% CI, 1.05-1.60) and 1.80 (95% CI, 1.45-2.23) relative to ED LOS <6 hours, respectively. The extended Cox regression showed that the risk lasted up to a week, with HRs of 1.42 (95% CI, 1.07-1.88) and 1.92 (95% CI, 1.44-2.57) relative to ED LOS <6 hours, respectively. In conclusion, Prolonged ED LOS is independently associated with HAPU. Shorter ED LOS should be pursued as a goal in a multifaceted solution for HAPU.

Abstract
OBJECTIVES Overcrowding in the emergency department (ED) is associated with increased morbidity and mortality. Studies have shown that consultation to decision time, defined as the time when a consultation has been accepted by a specialty service to the time when disposition decision is made, is one important contributor to the overall length of stay in the ED.The primary objective of this review is to evaluate the impact of workflow interventions on consultation to decision time and ED length of stay in patients referred to consultant services in teaching centres, and to identify barriers to reducing consultation to decision time. METHODS This systematic review was performed in accordance with the PRISMA guidelines. An electronic search was conducted to identify relevant studies from MEDLINE, EMBASE, Cochrane Central, and CINAHL databases. Study screening, data extraction, and quality assessment were carried out by two independent reviewers. RESULTS A total of nine full text articles were included in the review. All studies reported a decrease in consultation to decision time post intervention, and two studies reported cost savings. Interventions studied included short messaging service (SMS) messaging, education with audit and feedback, standardization of the admission process, implementation of institutional guideline, modification of the consultation process, and staffing schedules. Overall study quality was fair to poor. CONCLUSIONS The limited evidence suggests that audit and feedback in the form of SMS messaging, direct consultation to senior physicians, and standardization of the admission process may be the most effective and feasible interventions. Additional high-quality studies are required to explore sustainable interventions aimed at reducing consultation to decision time.

Risk Factors for Prolonged Length of Stay of Older Patients in an Academic Emergency Department: A Retrospective Cohort Study. Emerg Med Int 2019; 2019:4937827. [PMID: 31186963 PMCID: PMC6521575 DOI: 10.1155/2019/4937827] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Accepted: 04/09/2019] [Indexed: 11/18/2022] Open
Abstract
Emergency departments (EDs) are challenged with a growing population of older patients. These patients are at risk for a prolonged length of stay (LOS) at the ED and face more complications and poorer clinical outcomes. We aimed to identify risk factors for a prolonged LOS of older patients at the ED. For this retrospective clinical database study, we analyzed medical records of 2000 patients ≥70 years old presenting at the ED of a large level I trauma center in the Netherlands. LOS above the 75th percentile of LOS at our ED, 293 minutes, was considered prolonged. After bivariate analysis, we identified associations between LOS and patient, organizational, and clinical factors. Associations with a p < 0.05 were inserted in multivariable logistic regression models. We analyzed 1048 men (52%) and 952 women (48%) with a mean age of 78 ± 6.2 years. Risk factors for prolonged LOS of older patients at the ED were follows: higher number (more than one) of consultations (OR [odds ratio] 2.4, CI [confidence interval] 2.0-2.91), or diagnostic interventions (OR 1.5, CI 1.4-1.7); presenting complaints of a neurological (OR 2.2, CI 1.0-4.5) or internal medicine focus (OR 2.6, CI 1.4-4.6); patients with an altered consciousness (OR 3.3, CI 1.6-6.6); treatment by physicians of the departments of surgery (OR 3.4, CI 2.2-5.2), internal medicine (OR 2.6, CI 1.9-3.7), or pulmonology (OR 2.2, CI 1.4-3.6); and urgency category of ≥ U1. Awareness of factors associated with prolonged LOS of older patients presenting at the ED is essential. Physicians should recognize and take these factors into account, in order to improve clinical outcomes of the (strongly increasing) population of older patients at the ED.

Abstract
Abstract
Emergency departments (EDs) are the largest departments of hospitals which encounter high variety of cases as well as high level of patient volumes. Thus, an efficient classification of those patients at the time of their registration is very important for the operations planning and management. Using secondary data from the ED of an urban hospital, we examine the significance of factors while classifying patients according to their length of stay. Random Forest, Classification and Regression Tree, Logistic Regression (LR), and Multilayer Perceptron (MLP) were adopted in the data set of July 2016, and these algorithms were tested in data set of August 2016. Besides adopting and testing the algorithms on the whole data set, patients in these sets were grouped into 21 based on the similarities in their diagnoses and the algorithms were also performed in these subgroups. Performances of the classifiers were evaluated based on the sensitivity, specificity, and accuracy. It was observed that sensitivity, specificity, and accuracy values of the classifiers were similar, where LR and MLP had somehow higher values. In addition, the average performance of the classifying patients within the subgroups outperformed the classifying based on the whole data set for each of the classifiers.

Abstract
Emergency care in elderly patients has gained attention by researchers due to high utilization rate and the importance of emergency services in elderly care. We examine if there is a clear age threshold between young and old patients at which there is a need for extra care and facilities in the emergency department. This retrospective cohort study uses emergency department (ED) data collected over the course of a year, containing information about 31,491 patient visits. The measured variables are treatment time, waiting time, number of tests, number of medical procedures, number of specialties involved and the patient’s length of stay on the ED. To examine the multivariate differences between different patient groups, the data set is split into eighteen age groups and a MANOVA analysis is conducted to compare group means. The results show that older patients tend to have a longer stay on the ED. They also require more medical tests, have higher resource utilization and admission rates to the hospital. When the patients are grouped according to life stages (<18, 18-39, 40-64 and ≥65), each life stage shows significantly different characteristics across all variables. To understand where these differences start, age bins of five years are analyzed and almost none of the consecutive groups are significantly different in any variable. A significant difference between all groups is observed when age interval of the bins is increased to 10 years. This indicates that although age has an effect on the patient’s treatment, a clear age threshold that identifies the group of elderly patients is not observable from emergency room variables. The results of this study show no clear age boundary between young and old patients. In other words, we could not find support for favoring the often-used age boundary of 65 over other boundaries (e.g. 60 or 70) to distinguish the group of elderly patients on the ED.

Abstract
BACKGROUND Studies on the reliability of the MTS and its predictive power for hospitalisation and mortality in the older population have demonstrated mixed results. The objective is to evaluate the performance of the Manchester Triage System (MTS) in older patients (≥65 years) by assessing the predictive ability of the MTS for emergency department resource utilisation, emergency department length of stay (ED-LOS), hospitalisation, and in-hospital mortality rate. The secondary goal was to evaluate the performance of the MTS in older surgical versus medical patients. METHODS A retrospective cohort study was conducted of all emergency department visits by patients ≥65 years between 01 and 09-2011 and 31-08-2012. Performance of the MTS was assessed by comparing the association of the MTS with emergency department resource utilisation, ED-LOS, hospital admission, and in-hospital mortality in older patients and the reference group (18-64 years), and by estimating the area under the receiver operating characteristics curves. RESULTS Data on 7108 emergency department visits by older patients and 13,767 emergency department visits by patients aged 18-64 years were included. In both patient groups, a higher emergency department resource utilisation was associated with a higher MTS urgency. The AUC for the MTS and hospitalisation was 0.74 (95%CI 0.73-0.75) in older patients and 0.76 (95%CI 0.76-0.77) in patients aged 18-64 years. Comparison of the predictive ability of the MTS for in-hospital mortality in older patients with patients aged 18-64 years revealed an AUC of 0.71 (95%CI 0.68-0.74) versus 0.79 (95%CI 0.72-0.85). The majority of older patients (54.8%) were evaluated by a medical specialty and 45.2% by a surgical specialty. The predictive ability of the MTS for hospitalisation and in-hospital mortality was higher in older surgical patients than in medical patients (AUC 0.74, 95%CI 0.72-0.76 and 0.74, 95%CI 0.68-0.81 versus 0.69, 95%CI 0.67-0.71 and 0.66, 95%CI 0.62-0.69). CONCLUSION The performance of the MTS appeared inferior in older patients than younger patients, illustrated by a worse predictive ability of the MTS for in-hospital mortality in older patients. The MTS demonstrated a better performance in older surgical patients than older medical patients regarding hospitalisation and in-hospital mortality.

Abstract
Background Studies investigating different medical conditions and settings have demonstrated mixed results regarding the weekend effect. However, data on the outcome of elderly patients hospitalised on weekends is scarce. The objective was to compare in-hospital and two-day mortality rates between elderly emergency department (ED) patients (≥65 years) admitted on weekends versus weekdays. Methods A retrospective cohort study of emergency department visits of internal medicine patients ≥65 years presenting to the emergency department between 01 and 09-2010 and 31–08-2012 was conducted. The weekend was defined as the period from midnight on Friday to midnight on Sunday. Results Data on 3697 emergency department visits by elderly internal medicine patients (mean age 78.6 years old) were included. In total, 2743 emergency department visits (74.2%) resulted in hospitalisation, of which 22.9% occurred on weekends. Comorbidity and urgency levels were higher in patients admitted on weekends. In-hospital mortality was 11.4% for patients admitted on weekends compared with 8.9% on weekdays (OR 1.3, 95%CI 0.99–1.8). Two-day mortality was 3.2% in patients hospitalised on weekends versus 1.9% on weekdays (OR 1.7, 95%CI 0.99–2.9). Multivariable adjustment for age, comorbidity and triage level demonstrated comparable in-hospital and two-day mortality for weekend and week admission (ORadj 1.2, 95%CI 0.9–1.7 and ORadj 1.5, 95%CI 0.8–2.6, resp.). Conclusion A small weekend effect was observed in elderly internal medicine patients, which was not statistically significant. This effect was partly explained by a higher comorbidity and urgency level in elderly patients hospitalised on weekends than during weekdays. Emergency care for the elderly is not compromised by adjusted logistics during the weekend.

Abstract
Background Non-specific complaints (NSC) are common at the emergency department, but only a few studies have shown evidence that these complaints are associated with a poor prognosis in elderly emergency patients. Objective To describe patient characteristics and outcomes in a cohort of elderly emergency patients presenting with NSC. Outcomes were: patient characteristics, hospitalization, 90-day ED-return visits, and 30-day mortality. Method A retrospective cohort study was conducted amongst elderly patients present to the Internal Medicine Emergency Department (ED) between 01-09-2010 and 31-08-2011. NSC were defined as indefinable complaints that lack a pre-differential diagnosis needed to initiate of a standardized patient evaluation. Cox regression was performed to calculate Hazard Ratios (HR) and corrected for confounders such as comorbidity. Results In total, 1784 patients were enrolled; 244 (13.7%) presented with NSC. Compared to those with SC, comorbidity was higher in the NSC-group (Charlson comorbidity index 3.0 vs. 2.4, p<0.001). The triage level did not differ, but ED-length of stay was longer in the NSC-group (188 vs. 178 minutes, p = 0.004). Hospitalization was more frequent (84.0 vs. 71.1%, p<0.001) and the length of hospital stay (9 vs. 6 days, p<0.001 was longer in the NSC- than in the SC-group. The number of ED-return visits were comparable between both groups (HR 0.8, 95%CI 0.6–1.1). Mortality within 30-days was higher in the NSC- (20.1%) than in the SC-group (11.0%, HR 1.7 95%CI 1.2–2.4). Conclusion Elderly patients present with NSC at the ED regularly. These patients are more often hospitalized and have a substantially higher 30-day mortality than patients with SC.

Applicability of the modified Emergency Department Work Index (mEDWIN) at a Dutch emergency department. PLoS One 2017; 12:e0173387. [PMID: 28282406 PMCID: PMC5345800 DOI: 10.1371/journal.pone.0173387] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Accepted: 02/20/2017] [Indexed: 11/28/2022] Open
Abstract
Background Emergency department (ED) crowding leads to prolonged emergency department length of stay (ED-LOS) and adverse patient outcomes. No uniform definition of ED crowding exists. Several scores have been developed to quantify ED crowding; the best known is the Emergency Department Work Index (EDWIN). Research on the EDWIN is often applied to limited settings and conducted over a short period of time. Objectives To explore whether the EDWIN as a measure can track occupancy at a Dutch ED over the course of one year and to identify fluctuations in ED occupancy per hour, day, and month. Secondary objective is to investigate the discriminatory value of the EDWIN in detecting crowding, as compared with the occupancy rate and prolonged ED-LOS. Methods A retrospective cohort study of all ED visits during the period from September 2010 to August 2011 was performed in one hospital in the Netherlands. The EDWIN incorporates the number of patients per triage level, physicians, treatment beds and admitted patients to quantify ED crowding. The EDWIN was adjusted to emergency care in the Netherlands: modified EDWIN (mEDWIN). ED crowding was defined as the 75th percentile of mEDWIN per hour, which was ≥0.28. Results In total, 28,220 ED visits were included in the analysis. The median mEDWIN per hour was 0.15 (Interquartile range (IQR) 0.05–0.28); median mEDWIN per patient was 0.25 (IQR 0.15–0.39). The EDWIN was higher on Wednesday (0.16) than on other days (0.14–0.16, p<0.001), and a peak in both mEDWIN (0.30–0.33) and ED crowding (52.9–63.4%) was found between 13:00–18:00 h. A comparison of the mEDWIN with the occupancy rate revealed an area under the curve (AUC) of 0.86 (95%CI 0.85–0.87). The AUC of mEDWIN compared with a prolonged ED-LOS (≥4 hours) was 0.50 (95%CI 0.40–0.60). Conclusion The mEDWIN was applicable at a Dutch ED. The mEDWIN was able to identify fluctuations in ED occupancy. In addition, the mEDWIN had high discriminatory power for identification of a busy ED, when compared with the occupancy rate.

Bucak IH, Almis H. Does Abnormal Laboratory Results Notification with the Short Message Service Shorten Length of Stay in the Pediatric Emergency Department Observation Unit? Telemed J E Health 2016; 23:539-543. [PMID: 27935745 DOI: 10.1089/tmj.2016.0213] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/20/2022] Open
Abstract
BACKGROUND A new age in communications began with the entry into use of cell phones and their applications. Cell phones and their various applications must be actively used in patient monitoring in the healthcare system. INTRODUCTION The purpose of this study was to determine the length of stay in the pediatric emergency department observation unit (PEDOU) based upon the notification of abnormal laboratory results (ALRs) via the short message service (SMS). MATERIALS AND METHODS Patients with ALRs notified through the SMS (April-May-June 2015: study period) were evaluated retrospectively, and those admitted to hospital after such notification were enrolled as the study group (SG). Patients presenting to the pediatric emergency department (April-May-June 2014: control period), whose ALRs were not notified through the SMS, and who were hospitalized for treatment, were enrolled as the control group (CG). Age, sex, length of stay in the PEDOU (min), admission diagnosis, and receiving department were recorded for both groups. RESULTS Number of patients monitored in the PEDOU was 8584 during the study period and 8507 during the control period (p = 0.27). Length of stay of patients monitored in the PEDOU during the control period (n = 8507) and study period (n = 8584) was 136.4 and 133.5 min, respectively (p = 0.92). One hundred forty-seven patients were enrolled as the SG and 154 as the CG. Length of stay in the PEDOU was 221.1 ± 86.9 (65-542) min in the CG and 154.8 ± 76.6 (15-442) min in the SG (p < 0.001, 95% confidence interval: 47.5-84.8). CONCLUSIONS Notification of ALRs through the SMS does not affect length of stay in the PEDOU. Use of this method reduces length of stay of patients who require more rapid hospitalization.
