Risk factors for extremely long length-of-stay among pediatric emergency patients

Length of stay in the emergency department and its associated factors among pediatric patients attending Wolaita Sodo University Teaching and Referral Hospital, Southern, Ethiopia

BACKGROUND

Globally, there is an increase in the need for emergency department visits, which is exceptionally high in pediatric patients, resulting in longer lengths of stay, which is a global challenge and a hospital bottleneck that increases the risk of patient morbidity and mortality while also lowering satisfaction.

OBJECTIVE

This study aimed to assess the length of stay and associated factors in the pediatric emergency department at Wolaita Sodo University Hospital in 2021.

METHODS

An institution-based cross-sectional investigation was undertaken from March 15 to May 15, 2021. The 422 study participants were chosen using a systematic sampling procedure. The data were collected using semi-structured interviewer-administered questionnaires and chart reviews. Epi Data version 4.6 was used to enter the data, while SPSS version 26 was used to analyze it. With a 95% confidence interval, descriptive statistics were used to describe the prevalence, pediatrics, and emergency department duration of stay. The factors related to the length of stay were identified using bivariable and multivariable logistic regression analysis. On the AOR, a significant level was proclaimed when the p-value was less than 0.05, and the confidence interval was less than 95%.

RESULTS

The proportion of prolonged pediatric emergency department length of stay was 79.70% (95% CI; 75.7, 83.6). Nighttime arrival [AOR = 3.19, 95% CI (1.14, 8.98)], weekend arrival [AOR = 4.25, 95% CI (1.49, 5.35)], not receiving ordered medication in the hospital [AOR = 2.05, 95% CI (1.04, 4.03)], orange triage category [AOR = 4.01, 95% CI (1.60, 10.05)], and duration of pain 13-24 h [AOR = 0.29, 95% CI (0.89,0.98)], were significantly associated with length of stay.

CONCLUSION

The percentage of children who stayed in the pediatric emergency department for an extended period was high. Policymakers should implement evidence-based care, maximize existing resources, provide equal access to care and high-quality care, and make pediatric emergency departments more accessible and operationally efficient.

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.

Telemedicine Medical Screening Evaluation Expedites the Initiation of Emergency Care for Children

OBJECTIVE

Prior studies show that staffing a physician at triage expedites care in the emergency department. Our objective was to describe the novel application and effect of a telemedicine medical screening evaluation (Tele-MSE) at triage on quality metrics in the pediatric emergency department (PED).

METHODS

We conducted a retrospective quasi-experimental pre-post intervention study of patients presenting to an urban PED from December 2017 to November 2019 who received a Tele-MSE at triage. We analyzed 4 diagnostic cohorts: gastroenteritis, psychiatry evaluation, burn injury, and extremity fracture. We matched cases with controls who received standard triage, from December 2015 to November 2017, by age, diagnosis, weekday versus weekend, and season of presentation. Outcome measures included door-to-provider time, time-to-intervention order, and PED length of stay (LOS).

RESULTS

We included 557 patients who received Tele-MSE during the study period. Compared with controls, patients who received a Tele-MSE at triage had a shorter median door-to-provider time (median difference [MD], 8.4 minutes; 95% confidence interval [CI], 6.0-11.0), time-to-medication order (MD, 27.3 minutes; 95% CI, 22.9-35.2), time-to-consult order (MD, 10.0 minutes; 95% CI, 5.3-12.7), and PED LOS (MD, 0.4 hours; 95% CI, 0.3-0.6).

CONCLUSIONS

A Tele-MSE is an innovative modality to expedite the initiation of emergency care and reduce PED LOS for children. This novel intervention offers potential opportunities to optimize provider and patient satisfaction and safety during the COVID-19 pandemic.

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.

Factors Affecting Treatment with Life-Saving Interventions, Computed Tomography Scans and Specialist Consultations

Background: Emergency treatments determined by emergency physicians may affect mortality and patient satisfaction. This paper attempts to examine the impact of patient characteristics, health status, the accredited level of hospitals, and triaged levels on the following emergency treatments: immediate life-saving interventions (LSIs), computed tomography (CT) scans, and specialist consultations (SCs). Methods: A multivariate logistic regression model was employed to analyze the impact of patient characteristics, including sex, age, income and the urbanization degree of the patient's residence; patient health status, including records of hospitalization and the number of instances of ambulatory care in the previous year; the Charlson Comorbidity Index (CCI) score; the accredited level of hospitals; and the triaged level of emergency treatments. Results: All the patient characteristics were found to impact receiving LSI, CT and SC, except for income. Furthermore, a better health status was associated with a decreased probability of receiving LSI, CT and SC, but the number of instances of ambulatory care was not found to have a significant impact on receiving CT or SC. This study also found no evidence to support impact of CCI on SC. Hospitals with higher accredited levels were associated with a greater chance of patients receiving emergency treatments of LSI, CT and SC. A higher assigned severity (lower triaged level) led to an increased probability of receiving CT and SC. In terms of LSI, patients assigned to level 4 were found to have a lower chance of treatment than those assigned to level 5. Conclusions: This study found that several patient characteristics, patient health status, the accredited level of medical institutions and the triaged level, were associated with a higher likelihood of receiving emergency treatments. This study suggests that the inequality of medical resources among medical institutions with different accredited levels may yield a crowding-out effect.

The impact of the improvement in internal medicine consultation process on ED length of stay

INTRODUCTION

Although consultations are essential for delivering safe, high-quality care to patients in emergency departments, they contribute to emergency department patient flow problems and overcrowding which is associated with several adverse outcomes, such as increases in patient mortality and poor quality care. This study aimed to investigate how time flow metrics including emergency department length of stay is influenced by changes to the internal medicine consultation policy.

METHOD

This study is a pre- and post-controlled interventional study. We attempted to improve the internal medicine consultation process to be more concise. After the intervention, only attending emergency physicians consult internal medicine chief residents, clinical fellows, or junior staff of each internal medicine subspecialty who were on duty when patients required special care or an admission to internal medicine.

RESULTS

Emergency department length of stay of patients admitted to the department of internal medicine prior to and after the intervention decreased from 996.94min to 706.62min. The times from consultation order to admission order and admission order to emergency department departure prior to and after the intervention were decreased from 359.59min to 180.38min and from 481.89min to 362.37min, respectively. The inpatient mortality rates and Inpatient bed occupancy rates prior to and after the intervention were similar.

CONCLUSION

The improvements in the internal medicine consultation process affected the flow time metrics. Therefore, more comprehensive and cooperative strategies need to be developed to reduce the time cycle metrics and overcrowding of all patients in the emergency department.

Analyzing Factors Affecting Emergency Department Length of Stay-Using a Competing Risk-accelerated Failure Time Model

Emergency department (ED) length of stay (LOS) is associated with ED crowding and related complications. Previous studies either analyzed single patient disposition groups or combined different endpoints as a whole. The aim of this study is to evaluate different effects of relevant factors affecting ED LOS among different patient disposition groups.This is a retrospective electronic data analysis. The ED LOS and relevant covariates of all patients between January 2013 and December 2013 were collected. A competing risk accelerated failure time model was used to compute endpoint type-specific time ratios (TRs) for ED LOS.A total of 149,472 patients was included for analysis with an overall medium ED LOS of 2.15 [interquartile range (IQR) = 6.51] hours. The medium LOS for discharged, admission, and mortality patients was 1.46 (IQR = 2.07), 11.3 (IQR = 33.2), and 7.53 (IQR = 28.0) hours, respectively. In multivariate analysis, age (TR = 1.012, P < 0.0001], higher acuity (triage level I vs level V, TR = 2.371, P < 0.0001), pediatric nontrauma (compared with adult nontrauma, TR = 3.084, P < 0.0001), transferred patients (TR = 2.712, P < 0.0001), and day shift arrival (compared with night shift, TR = 1.451, P < 0.0001) were associated with prolonged ED LOS in the discharged patient group. However, opposite results were noted for higher acuity (triage level I vs level V, TR = 0.532, P < 0.0001), pediatric nontrauma (TR = 0.375, P < 0.0001), transferred patients (TR = 0.852, P < 0.0001), and day shift arrival (TR = 0.88, P < 0.0001) in the admission patient group.Common influential factors such as age, patient entity, triage acuity level, or arrival time may have varying effects on different disposition groups of patients. These findings and the suggested model could be used for EDs to develop individually tailored approaches to minimize ED LOS and further improve ED crowding status.

C-Reactive Protein Bedside Testing in Febrile Children Lowers Length of Stay at the Emergency Department

BACKGROUND

C-Reactive protein (CRP) is an important diagnostic marker for serious bacterial infections in febrile children. C-Reactive protein bedside testing could potentially accelerate the diagnostic evaluation and shorten length of stay (LOS).

OBJECTIVE

The aim of the study was to study the effect of introducing CRP bedside testing on the LOS of febrile children at the emergency department (ED).

DESIGN AND INTERVENTION

A prospective observational study with a preimplementation cohort (2008) with traditional CRP testing and a postimplementation cohort (2009-2011) in which CRP bedside testing was introduced.

PATIENTS AND SETTING

All previously healthy children with fever, aged 1 month to 16 years, attending the ED of a university hospital were included; non-ill-appearing children with an upper airway infection were not eligible for CRP bedside testing.

ANALYSIS AND MAIN OUTCOME MEASURE

Multivariable linear regression and propensity score analyses were used to determine the effect of CRP bedside testing on the logarithmic transformation length of stay [(log)LOS].

RESULTS

The preimplementation cohort included 609 children of whom 286 (47%) had traditional CRP. The postimplementation cohort included the following 1330 children: 728 (55%) children had bedside CRP and 156 (12%) children had traditional CRP. Bedside CRP significantly lowered the median LOS of children in whom an additional diagnostic CRP test was performed, from 178 minutes (interquartile range, 135-232 minutes) to 148 minutes (interquartile range, 108-200 minutes) (30 minutes, 19% of total LOS). A significant reduction of 15% of the (log)LOS remained after adjusting for other determinants of (log)LOS; propensity score analysis showed a 16% reduction.

CONCLUSIONS

C-Reactive protein bedside testing substantially lowered the LOS of children with fever at the ED in whom an additional diagnostic CRP test was performed.

Bedside ultrasonography as an adjunct to routine evaluation of acute appendicitis in the emergency department

Introduction

Appendicitis is a common condition presenting to the emergency department (ED). Increasingly emergency physicians (EP) are using bedside ultrasound (BUS) as an adjunct diagnostic tool. Our objective is to investigate the test characteristics of BUS for the diagnosis of appendicitis and identify components of routine ED workup and BUS associated with the presence of appendicitis.

Methods

Patients four years of age and older presenting to the ED with suspected appendicitis were eligible for enrollment. After informed consent was obtained, BUS was performed on the subjects by trained EPs who had undergone a minimum of one-hour didactic training on the use of BUS to diagnose appendicitis. They then recorded elements of clinical history, physical examination, white blood cell count (WBC) with polymophonuclear percentage (PMN), and BUS findings on a data form. We ascertained subject outcomes by a combination of medical record review and telephone follow-up.

Results

A total of 125 subjects consented for the study, and 116 had adequate image data for final analysis. Prevalence of appendicitis was 40%. Mean age of the subjects was 20.2 years, and 51% were male. BUS was 100% sensitive (95% CI 87–100%) and 32% specific (95% CI 14–57%) for detection of appendicitis, with a positive predictive value of 72% (95% CI 56–84%), and a negative predictive value of 100% (95% CI 52–100%). Assuming all non-diagnostic studies were negative would yield a sensitivity of 72% and specificity of 81%. Subjects with appendicitis had a significantly higher occurrence of anorexia, nausea, vomiting, and a higher WBC and PMN count when compared to those without appendicitis. Their BUS studies were significantly more likely to result in visualization of the appendix, appendix diameter >6mm, appendix wall thickness >2mm, periappendiceal fluid, visualization of the appendix tip, and sonographic Mcburney’s sign (p<0.05). In subjects with diagnostic BUS studies, WBC, PMN, visualization of appendix, appendix diameter >6mm, appendix wall thickness >2mm, periappendiceal fluid were found to be predictors of appendicitis on logistic regression.

Conclusion

BUS is moderately useful for appendicitis diagnosis. We also identified several components in routine ED workup and BUS that are associated with appendicitis generating hypothesis for future studies.

Children's Mental Health Visits to the Emergency Department: Factors Affecting Wait Times and Length of Stay

Objective. This study explores the association of patient and emergency department (ED) mental health visit characteristics with wait time and length of stay (LOS). Methods. We examined data from 580 ED mental health visits made to two urban EDs by children aged ≤18 years from April 1, 2004, to March 31, 2006. Logistic regressions identified characteristics associated with wait time and LOS using hazard ratios (HR) with 95% confidence intervals (CIs). Results. Sex (male: HR = 1.48, 95% CI = 1.20-1.84), ED type (pediatric ED: HR = 5.91, 95% CI = 4.16-8.39), and triage level (Canadian Triage and Acuity Scale (CTAS) 2: HR = 3.62, 95% CI = 2.24-5.85) were statistically significant predictors of wait time. ED type (pediatric ED: HR = 1.71, 95% CI = 1.18-2.46), triage level (CTAS 5: HR = 2.00, 95% CI = 1.15-3.48), number of consultations (HR = 0.46, 95% CI = 0.31-0.69), and number of laboratory investigations (HR = 0.75, 95% CI = 0.66-0.85) predicted LOS. Conclusions. Based on our results, quality improvement initiatives to reduce ED waits and LOS for pediatric mental health visits may consider monitoring triage processes and the availability, access, and/or time to receipt of specialty consultations.

Factors affecting length of stay in the pediatric emergency department

BACKGROUND

A large volume of visits can cause an emergency department (ED) to become overcrowded, resulting in a longer length of stay (LOS). The objective of this study was to analyze factors affecting the LOS in the pediatric ED.

METHODS

Records of all visits to the pediatric ED of the study hospital, from July 1, 2006 to June 31, 2007, were retrospectively retrieved. Data were collected from the hospital's computerized records system. Eta-squared correlation ratio and Cramer's V test evaluated the associations between variables. Two-thirds of the database was randomized for the classification and regression tree (CART) model-building dataset, and one-third was used for the validation dataset.

RESULTS

A total of 29,035 patients visited the pediatric ED during the evaluation period. Of the total visits, 61.1% were due to complaints of fever. The mean LOS was 2.6 ± 4.67 hours, and 74.3% of visits had an LOS of shorter than 2 hours. The CART analysis selected five factors (waiting time for hospitalization, laboratory tests, door-to-physician time, gastrointestinal symptoms, and patient outcome) to produce a total of nine subgroups of patients. The mean LOS of the model-building dataset closely correlated with that of the validation dataset (r(2) = 0.999).

CONCLUSION

Patients who were waiting for hospitalization for less than 8 hours or were not admitted, those without any laboratory tests, those having door-to-physician time less than 60 minutes, and those without any gastrointestinal symptoms had the shortest LOS. Patients who waited for hospitalization for more than 16 hours had the longest LOS.

Factors associated with prolonged stay in a pediatric emergency observation unit of an urban tertiary children's hospital in China

OBJECTIVES

This study aimed to examine the factors associated with increased length of stay (LOS > 24 hours) in the pediatric emergency observation unit (OU) of an urban tertiary children's hospital in China.

METHODS

This study was a retrospective cohort study. We retrieved and examined all the records of patients (age, 0-16 years) who were admitted to the OU (n = 10,852) during July 1, 2008, to June 30, 2009. The primary outcome was LOS and prolonged stay (LOS > 24 hours). We also performed a sensitivity analysis by using LOS of 3 days or greater and LOS of 6 days or greater as dependent variables in logistic regression and compared with LOS of greater than 24 hours regression to examine the robustness of the associations.

RESULTS

The overall mean (SD) LOS was 24.0 (24.4) hours; 31.3% had LOS of greater than 24 hours, of which the mean (SD) LOS was 50.2 (28.6) hours. The following factors were associated with LOS of greater than 24 hours: age, 28 days to 3 months (odds ratio, [OR], 1.87; 95% confidence interval, 1.36-2.59) and older than 3 months to 12 months (OR, 1.83; 95% CI, 1.35-2.50) compared with age 0 to 28 days; neurologic diseases (OR, 1.50; 95% CI, 1.31-1.72), infectious diseases (OR, 2.00; 95% CI, 1.61-2.49), and visits for non-respiratory-related signs and symptoms (OR, 2.00; 95% CI, 1.61-2.49); acuity level of emergent (OR, 1.79; 95% CI, 1.57-2.04); procedures (OR, 7.09; 95% CI, 4.16-12.10); emergency transfusions (OR, 1.33; 95% CI, 1.01-1.75); staffed by residents (OR, 1.12; 95% CI, 1.01-1.24); and patients living in low-annual gross domestic product districts (OR, 1.14; 95% CI, 1.01-1.29). Arrival at evening (OR, 0.54; 95% CI, 0.49-0.60) and overnight (OR, 0.43; 95% CI, 0.38-0.49) were less likely to have LOS of greater than 24 hours than arrival during day shifts.

CONCLUSIONS

We identified some risk factors for prolonged stay in an OU. These factors are the starting points in understanding issues related to prolonged stay and are needed to assess efficiency and quality of care in pediatric emergency department and OU. Our results have provided information basis for making improvements in the system and may be important considerations for similar institutions, which encounter similar challenges.

Bottlenecks in the emergency department: the psychiatric clinicians' perspective

OBJECTIVE

To ask psychiatric clinicians for their perspectives on the rate-limiting steps (RLS) in patient care in the Emergency Department (ED) and to compare them to the patient's actual length of stay.

METHOD

Prospective cohort study of clinicians' perspectives on the RLS among 1092 adult ED patients. Medical records were abstracted for ED time and other data.

RESULTS

Clinicians identified five RLS: limited availability of staff, limited availability of beds after discharge, need for clinical stability, need for additional history and patient's financial issues. The last RLS was the only one not associated with increased wait times in the ED. There were significant differences in the patterns of RLS by trainee status and hospital. For example, significantly higher proportions of trainees reported that RLS in patient care were due to the need for clinical stability and additional history and lack of bed availability. In contrast, non-trainee clinicians were more likely to cite problems with the availability of ED staff as an RLS.

CONCLUSIONS

Most of the RLS in patient care identified by clinicians were associated with actual increases in ED wait time for their patients. Next steps include asking clinicians for possible solutions to the delays their patients experience.

Predictors of psychiatric boarding in the pediatric emergency department: implications for emergency care

OBJECTIVES

Patients who present to the emergency department (ED) and require psychiatric hospitalization may wait in the ED or be admitted to a medical service because there are no available inpatient psychiatric beds. These patients are psychiatric "boarders." This study describes the extent of the boarder problem in a large, urban pediatric ED, compares characteristics of psychiatrically hospitalized patients with boarders, and compares predictors of boarding in 2 ED patient cohorts.

METHODS

A retrospective cohort study was conducted in 2007-2008. The main outcome measure was placement into a psychiatric facility or boarding. Predictors of boarding in the present analysis were compared with predictors from a similar study conducted in the same ED in 1999-2000.

RESULTS

Of 461 ED patient encounters requiring psychiatric admission, 157 (34.1%) boarded. Mean and median boarding duration for the sample were 22.7(SD, 8.08) and 21.18 hours, respectively. Univariate generalized estimating equations demonstrated increased boarding odds for patients carrying Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnoses of autism, mental retardation, and/or developmental delay (P = 0.01), presenting during the weekend (P = 0.03) or presenting during months without school vacation (P = 0.02). Suicidal ideation (SI) significantly predicted boarding status, with increased likelihood of boarding for severe SI (P = 0.02). Age, race, insurance status, and homicidal ideation did not significantly predict boarding in the 2007-2008 patient cohort, although they did in the earlier study. Systemic factors and SI predicted boarding status in both cohorts.

CONCLUSIONS

Suicidal patients continue to board. Limits within the system, including timing of ED presentation and a dearth of specialized services, still exist, elevating the risk of boarding for some populations. Implications for pediatric ED psychiatric care delivery are discussed.

Quality initiatives in the emergency department

PURPOSE OF REVIEW

To report on recent advances in quality initiatives in emergency departments (EDs), with a special focus on applicability to pediatric EDs (PED) RECENT FINDINGS: Although healthcare quality improvement has made great strides in the last couple of decades, quality improvement efforts in pediatrics have lagged behind. Over the last decade, as quality initiatives have matured in adult hospitals, there has been a downstream effect on general EDs, as system-wide clinical guidelines are usually initiated through the ED--such efforts are being reported in the literature. There is significant overlap in quality improvement efforts in adult and pediatric EDs. In this article, we review the recent relevant articles, with particular emphasis on pediatrics where appropriate.

SUMMARY

There is an opportunity in pediatric emergency medicine to reduce practice variability, decrease cost and improve efficiency of care. There is an urgent need to report the successes and failures of these initiatives, so we can develop benchmarks and optimize services provided in the PED.
