Patient and organizational characteristics predict a long length of stay in the emergency department - a Swedish cohort study

Diagnosing an overcrowded emergency department from its Electronic Health Records

Emergency department overcrowding is a complex problem that persists globally. Data of visits constitute an opportunity to understand its dynamics. However, the gap between the collected information and the real-life clinical processes, and the lack of a whole-system perspective, still constitute a relevant limitation. An analytical pipeline was developed to analyse one-year of production data following the patients that came from the ED (n = 49,938) at Uppsala University Hospital (Uppsala, Sweden) by involving clinical experts in all the steps of the analysis. The key internal issues to the ED were the high volume of generic or non-specific diagnoses from non-urgent visits, and the delayed decision regarding hospital admission caused by several imaging assessments and lack of hospital beds. Furthermore, the external pressure of high frequent re-visits of geriatric, psychiatric, and patients with unspecified diagnoses dramatically contributed to the overcrowding. Our work demonstrates that through analysis of production data of the ED patient flow and participation of clinical experts in the pipeline, it was possible to identify systemic issues and directions for solutions. A critical factor was to take a whole systems perspective, as it opened the scope to the boundary effects of inflow and outflow in the whole healthcare system.

[Characteristics of older versus younger emergency patients : Analysis of over 356,000 visits from the AKTIN German emergency department data registry]

BACKGROUND

This nationwide study aims to analyze age-specific differences and characteristics of emergency patients with a special focus on older patients.

METHOD

In 2019, data were obtained from 11 emergency departments (EDs), all part of the German Emergency Department Data (AKTIN) registry. All patients 18 years and older visiting the EDs were included. In addition to demographic data, variables such as referral, type of transport, primary assessment, diagnoses, length of stay and type of transfer were recorded and compared by age group and specifically by younger (18-64 years) and older patients (65+ years).

RESULTS

Data from 356,354 patients (39.1% were aged 65+ years) were included. Compared to younger patients, older ED patients were more likely to be accompanied by emergency medical services (15.4 vs. 34.3%) and almost twice as often by an emergency physician (6.4 vs. 12.2%). The need for treatment increased with age; 47.1% of younger and 66.1% of older people were classified as yellow, orange or red. The proportion of patients with internal diseases was higher for patients 65+ years (22.5 vs. 38.8%). Older patients were more often hospitalized (27.5 vs. 60.3%) and were more frequently transferred to an intensive care unit (4.5 vs. 11.9%).

CONCLUSION

About 40% of adult emergency patients are 65+ years. They require more urgent treatment and are more often hospitalized than younger patients. In older patients, internal diseases were more common.

Prevalence of frailty and associated factors in older adults seeking care at Swedish emergency departments

BACKGROUND

Internationally, prolonged length of stay for older adults in the emergency department (ED) is associated with increased risk of in-hospital adverse events. In Sweden patients 65 years and older account for 35% of emergency visits, and according to consensus from an international expert group, all persons over 70 should be screened for frailty. This is not routinely done in Swedish EDs, and therefore, knowledge about prevalence, characteristics and clinical outcomes associated with frailty is limited.

AIM

To describe the prevalence of frailty and associated factors in older adults seeking care at Swedish EDs.

METHODS

The study has a cross-sectional design. Data was collected at three hospital-based EDs, varying in level and size of setting, for one month. Patients age 70 and older presenting at the EDs and agreed to participate were screened for frailty using the FRail Elderly Support researcH group (FRESH) instrument. Data were analysed using descriptive statistics to assess the distribution of patient characteristics and clinical outcomes. Multivariate logistic regression was used to model the association between frailty and demographic characteristics, and Cox regression was used to model the association between frailty and clinical outcomes.

RESULTS

A total of 3101 patients were eligible for inclusion; of these, 984 (32%) were included and screened for frailty. Of the final sample, 57.3% were assessed as frail. Characteristics significantly associated with frailty were living in a residential care facility, age (> 80 years), being a woman and arriving with emergency medical service (EMS). There was a significant association between frailty and admittance to in-hospital care.

CONCLUSION

Our study shows a high prevalence of frailty in older people. Factors associated with frailty were living in a residential care facility, age ≥ 80 years, being a woman and arriving with EMS to the ED and being admitted to in-hospital care. Frailty screening should be incorporated in the triage system to identify frail patients who need tailored interventions. More studies using the FRESH instrument are needed to further confirm our findings and to develop the methods for screening for frailty in the ED.

Socioeconomic status is associated with process times in the emergency department for patients with chest pain

Objective

Emergency department length of stay (EDLOS) is linked to crowding and patient outcomes whereas worse prognosis in low socioeconomic status remains poorly understood. We studied whether income was associated with ED process times among patients with chest pain.

Methods

This was a registry-based cohort study on 124,980 patients arriving at 14 Swedish EDs between 2015 and 2019 with chest pain as their chief complaint. Individual-level sociodemographic and clinical data were linked from multiple national registries. The associations between disposable income quintiles, whether the time to physician assessment exceeded triage priority recommendations as well as EDLOS were evaluated using crude and multivariable regression models adjusted for age, gender, sociodemographic variables, and ED-management circumstances.

Results

Patients with the lowest income were more likely to be assessed by physician later than triage recommendations (crude odds ratio [OR] 1.25 (95% confidence interval [CI] 1.20-1.29) and have an EDLOS exceeding 6 h (crude OR 1.22 (95% CI 1.17-1.27). Among patients subsequently diagnosed with major adverse cardiac events, patients with the lowest income were more likely to be assessed by a physician later than triage recommendations, crude OR 1.19 (95% CI 1.02-1.40). In the fully adjusted model, the average EDLOS was 13 min (5.6%) longer among patients in the lowest income quintile, 4:11 [h:min], (95% CI 4:08-4:13), compared to patients in the highest income quintile, 3:58 (95% CI 3:56-4:00).

Conclusions

Among ED chest pain patients, low income was associated with longer time to physician than recommended by triage and longer EDLOS. Longer process times may have a negative impact due to crowding in the ED and delay diagnosis and timely treatment of the individual patient.

Prolonged length of stay and its associated factors at adult emergency department in amhara region comprehensive specialized hospitals, northwest Ethiopia

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.

Fundamental nursing actions for frail older people in the emergency department: A national cross-sectional survey and a qualitative analysis of practice guidelines

AIMS

To map how frailty among older people is assessed at Swedish emergency departments and to describe fundamental nursing care actions for these patients.

DESIGN

Descriptive national survey and a qualitative analysis of text.

METHODS

A majority (82%, n = 54) of the Swedish hospital-based emergency departments for adults were included, representing all six healthcare regions. An online survey was used to collect data, together with submitted local practice guidelines for older people at the emergency departments. Data were collected during February-October 2021. Descriptive and comparative statistics were performed together with a deductive content analysis framed by the Fundamentals of Care framework.

RESULTS

Sixty-five per cent (35 of 54) of the emergency departments identified frailty, with less than half of them using an established assessment instrument. Twenty-eight (52%) of the emergency departments have practice guidelines containing fundamental nursing actions for the care of frail older people. The majority of nursing actions in the practice guidelines were related to patients' physical care needs (91%), followed by psychosocial care needs (9%). No actions could be identified as relational actions (0%) according to the Fundamentals of Care framework.

CONCLUSION

Many Swedish emergency departments identify frail older people, but they use a range of different assessment instruments. While practice guidelines directing fundamental nursing actions for frail older people are often in place, a holistic, person-centred view addressing the patient's physical, psychosocial and relational care needs is missing.

IMPACT

The population is growing older, and more people are needing more complex hospital care. Frail older people have an increased risk of negative outcomes. The use of a variety of assessment instruments for frailty may pose a challenge to equal care. To ensure a holistic, person-centred view of frail older people, the Fundamentals of Care framework can be used in developing and reviewing practice guidelines.

PATIENT OR PUBLIC CONTRIBUTION

Clinicians and non-health professionals were invited to review the survey to ensure face and content validity.

Patient and hospital characteristics predict prolonged emergency department length of stay and in-hospital mortality: a nationwide analysis in Korea

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.

Length of stay as quality indicator in emergency departments: analysis of determinants in the German Emergency Department Data Registry (AKTIN registry)

Several indicators reflect the quality of care within emergency departments (ED). The length of stay (LOS) of emergency patients represents one of the most important performance measures. Determinants of LOS have not yet been evaluated in large cohorts in Germany. This study analyzed the fixed and influenceable determinants of LOS by evaluating data from the German Emergency Department Data Registry (AKTIN registry). We performed a retrospective evaluation of all adult (age ≥ 18 years) ED patients enrolled in the AKTIN registry for the year 2019. Primary outcome was LOS for the whole cohort; secondary outcomes included LOS stratified by (1) patient-related, (2) organizational-related and (3) structure-related factors. Overall, 304,606 patients from 12 EDs were included. Average LOS for all patients was 3 h 28 min (95% CI 3 h 27 min-3 h 29 min). Regardless of other variables, patients admitted to hospital stayed 64 min longer than non-admitted patients. LOS increased with patients' age, was shorter for walk-in patients compared to medical referral, and longer for non-trauma presenting complaints. Relevant differences were also found for acuity level, day of the week, and emergency care levels. We identified different factors influencing the duration of LOS in the ED. Total LOS was dependent on patient-related factors (age), disease-related factors (presentation complaint and triage level), and organizational factors (weekday and admitted/non-admitted status). These findings are important for the development of management strategies to optimize patient flow through the ED and thus to prevent overcrowding.

Profile and outcomes of emergency department presentations based on mode of arrival: A state-wide retrospective cohort study

OBJECTIVE

Understanding how people arrive to the ED assists in planning health services' response to fluctuating ED demand. The present study aimed to describe and compare demographics, clinical characteristics and health service outcomes of adult ED patient presentations based on mode of arrival: brought in by police (BIBP)/brought in by ambulance (BIBA)/privately arranged transport (PAT).

METHODS

A retrospective cohort study of ED patient presentations made between 1 January 2018 and 31 December 2020 from all public hospital EDs across Queensland, Australia. Descriptive and inferential analyses were performed to ascertain presentation characteristics and predictors of health service outcomes.

RESULTS

From 4 707 959 ED presentations, 0.9% were BIBP, 34.8% were BIBA and 64.0% were PAT. Presentations BIBP were younger and comprised a higher proportion of mental health problems and Emergency Examination Authority orders compared to presentations BIBA or PAT. Compared to presentations BIBP or PAT, presentations BIBA were more likely to be assigned more urgent triage scores, be admitted to hospital, and have a longer ED length of stay (LOS). Compared to other modes of arrival, presentations arriving by PAT were more likely to be discharged and have a shorter ED LOS.

CONCLUSION

Presentations BIBA and BIBP encountered a longer ED LOS and higher admission rates than PAT, suggesting more complex care needs than those from PAT. Clinical care pathways for specific modes of arrival that support pre-hospital providers and patients and are considerate of the throughput and output stages of ED care may be needed.

Does crowding influence emergency department treatment time and disposition?

OBJECTIVE

The objective of this study was to determine whether crowding influences treatment times and disposition decisions for emergency department (ED) patients.

METHODS

We conducted a retrospective cohort study at 2 hospitals from January 1, 2014, to July 1, 2014. Adult ED visits with dispositions of discharge, admission, or transfer were included. Treatment times were modeled by linear regression with log-transformation; disposition decisions (admission or transfer vs discharge) were modeled by logistic regression. Both models adjusted for chief complaint, Emergency Severity Index (ESI), and 4 crowding metrics in quartiles: waiting count, treatment count, boarding count, and National Emergency Department Overcrowding Scale.

RESULTS

We included 21,382 visits at site A (12.9% excluded) and 29,193 at site B (15.0% excluded). Respective quartiles of treatment count increased treatment times by 7.1%, 10.5%, and 13.3% at site A (P < 0.001) and by 4.0%, 6.5%, and 10.2% at site B (P < 0.001). The fourth quartile of treatment count increased estimates of treatment time for patients with chest pain and ESI level 2 from 2.5 to 2.9 hours at site A (20 minutes) and from 3.0 to 3.3 hours at site B (18 minutes). Treatment times decreased with quartiles of waiting count by 5.6%, 7.2%, and 7.3% at site B (P < 0.001). Odds of admission or transfer increased with quartiles of waiting count by 8.7%, 9.6%, and 20.3% at site A (P = 0.011) and for the third (11.7%) and fourth quartiles (27.3%) at site B (P < 0.001).

CONCLUSIONS

Local crowding influenced ED treatment times and disposition decisions at 2 hospitals after adjusting for chief complaint and ESI.

Long emergency department length of stay: A concept analysis

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.

Socio-demographic differences in the frequent use of emergency department care by older persons: a population-based study in Stockholm County

BACKGROUND

In Sweden, the number of older people using emergency department (ED) care is rising. Among older persons an ED visit is a stressful event, which potentially could have been prevented or treated at other levels of care. Frequent ED use (> 4 visits a year) by older persons might reflect issues in the organisation of health care system to address their needs. We aimed to explore socio-demographic differences among older people seeking ED care in terms age and gender, and to investigate the association between income and frequent ED use.

METHODS

A population-based study analysing the utilisation of ED care by (N = 356,375) individuals aged 65+ years. We linked register data on socio-demographic characteristics from 2013 to health care utilisation data in 2014. Multivariable logistic regression was used to estimate the income differences in the frequent use of ED care, adjusting for living situation, country of birth, residential area, age in years, multi-morbidity and the use of other health care services.

RESULTS

Those 65+ years accounted for (27%) of all ED visits in Stockholm County in 2014. In the study population (2.5%) were identified as frequent ED users, who were predominantly in the lower income groups, living alone or in an institution, had more multi-morbidity, and utilised more of other health care services. The lowest income groups had a three-fold greater odds of being a frequent ED user than those in the highest income group. In the adjusted models, the odds were reduced by 12-44% for those in the lowest income groups. However, age and gender differences were observed with men 65-79 years (OR 1.75 CI: 1.51-2.03) and women 80+ years (OR 1.50, CI 1.19-1.87) in the lowest income groups having a higher odds of frequent ED use.

CONCLUSION

This study observed that ED visits by older persons are driven by a need of care, and those that frequently visit hospital-based EDs are a socially disadvantaged group, which suggests that the organisation of care for older people should be reviewed in order to better meet their needs in other levels of care.

Effect of crowding on length of stay for common chief complaints in the emergency department: A STROBE cohort study

Crowding in emergency departments (EDs) is associated with long lengths of stay (LOS); however, it is not known whether the effect is equal across different chief complaints.The aim of the study was to compare the effect of crowding on LOS in the 10 most common medical or surgical chief complaints in the ED.All adult visits to a university hospital ED on weekdays between 8 AM and 9 PM in 2012 (n = 19,200) were stratified based on chief complaint and triage priority. The ED bed occupancy rate was measured and crowding was defined as an occupancy rate over one. The impact of crowding on LOS was calculated for the different groups.During crowding, LOS was longer among all chief complaints (P ≤.01) (except for high-acuity patients with wounds, where the study group was very small). During crowding, LOS increased the most among patients with extremity pain/swelling (145% among high-acuity patients, 125% among low-acuity patients) and flank pain (87% among high-acuity patients, 117% among low-acuity patients) and the least among patients with chest pain (32% among high-acuity patients, 45% among low-acuity patients) or arrhythmia (37% among high-acuity patients, 52% among low-acuity patients).The effect of ED crowding on LOS is unequal across different chief complaints. These findings could be used to improve the processing of specific chief complaints in the ED.
