Undertriage in older emergency department patients--tilting against windmills?

Association of Emergency Department Length of Stay and Hospital Mortality in Patients Under Investigation for COVID-19

Objective

We aimed to determine the association between hospital mortality of patients under investigation (PUI) for COVID-19 and emergency department length of stay (EDLOS).

Patients and Methods

A retrospective study was conducted from April 3, 2020 to April 2, 2022. Adult PUI who presented with both clinical and epidemiological risk factors for COVID-19 disease and underwent sample collection with nasal swab for reverse transcription polymerase chain reaction were included in the study. The factors associated with EDLOS and hospital mortality were investigated using univariate logistic regression and multivariate logistic regression analyses.

Results

A total of 961 PUI were enrolled that included 836 (87%) non-COVID-19 patients. The median (interquartile range [IQR]) EDLOS durations for 7-day and 30-day mortality of all PUI were 3.1 hours (2.1,4.3, P = 0.231) and 3.2 hours (2.1,4.3, P = 0.653). Multivariate logistic regression analysis revealed that the significant factors associated with EDLOS longer than 4 hours were consultation of three departments (adjusted odds ratio (aOR) 27.3, 95% CI 2.42-309.71, P = 0.007), emergency severity index (ESI) level 3 (aOR 2.31, 95% CI 1.37-3.9), investigations >2 (aOR 2.62, 95% CI 1.62-4.25), nebulization (aOR 2.34, 95% CI 1.39-3.96), administration of intravenous fluid (aOR 2.62, 95% CI 1.59-4.33), performing ≥1 procedure (aOR 3.35, 95% CI 1.51-7.43), and discharged patients (aOR 2.13, 95% CI 1.02-4.48).

Conclusion

The significant factors associated with prolonged EDLOS in PUI included consultation of three departments, ESI level 3, investigations >2, ED treatment, ED procedures, and discharged patients. The median times of EDLOS and hospital LOS were 3.2 hours and 5.7 days. The EDLOS had no significant association with short-term mortality.

Characteristics of undertriaged older patients in the emergency department: Retrospective study

BACKGROUND

Older patients are more likely to be undertriaged as they often suffer from multiple diseases and complain of non-specific symptoms. Therefore, it is necessary to identify the characteristics of undertriaged older patients in emergency departments.

METHODS

This descriptive study retrospectively reviewed and analyzed the electronic medical records of older patients who visited the emergency department of a general hospital in Seoul between January and December 2019.

RESULTS

Approximately 29 % (n = 4,823) of older patients who visited the emergency department during the study period were classified as Korean Triage and Acuity Scale (KTAS) level 4 or 5, and approximately 8 % (n = 397) were undertriaged. Approximately 73 % (n = 288) of patients were hospitalized after visiting the emergency department. The undertriaged older patients exhibited nervous system symptoms such as dizziness and headache (28.8 %), cardiopulmonary symptoms such as chest discomfort, palpitations, and abdominal pain (28.4 %), head trauma (12.8 %), and respiratory symptoms such as cough and dyspnea (12.5 %).

CONCLUSION

Triage nurses in emergency departments should carefully triage older patients as their chief complaints can be non-specific. In particular, when older patients visit the emergency department and exhibit symptoms such as dizziness, abnormal pain, chest discomfort, palpitations, and head trauma, they are more likely to be admitted to the intensive care unit. Therefore, meticulous care for older patients showing these symptoms is essential.

[Clinical acute and emergency medicine curriculum-focus on internal medicine : Recommendations for advanced training in internal medicine in the emergency department]

In Germany, physicians qualify for emergency medicine by combining a specialty medical training-e.g. internal medicine-with advanced training in emergency medicine according to the statutes of the State Chambers of Physicians largely based upon the Guideline Regulations on Specialty Training of the German Medical Association. Internal medicine and their associated subspecialities represent an important column of emergency medicine. For the internal medicine aspects of emergency medicine, this curriculum presents an overview of knowledge, skills (competence levels I-III) as well as behaviours and attitudes allowing for the best treatment of patients. These include general aspects (structure and process quality, primary diagnostics and therapy as well as indication for subsequent treatment; resuscitation room management; diagnostics and monitoring; general therapeutic measures; hygiene measures; and pharmacotherapy) and also specific aspects concerning angiology, endocrinology, diabetology and metabolism, gastroenterology, geriatric medicine, hematology and oncology, infectiology, cardiology, nephrology, palliative care, pneumology, rheumatology and toxicology. Publications focussing on contents of advanced training are quoted in order to support this concept. The curriculum has primarily been written for internists for their advanced emergency training, but it may generally show practising emergency physicians the broad spectrum of internal medicine diseases or comorbidities presented by patients attending the emergency department.

Geriatric Population Triage: The Risk of Real-Life Over- and Under-Triage in an Overcrowded ED: 4- and 5-Level Triage Systems Compared: The CREONTE (Crowding and R E Organization National TriagE) Study

Elderly patients, when they present to the emergency department (ED) or are admitted to the hospital, are at higher risk of adverse outcomes such as higher mortality and longer hospital stays. This is mainly due to their age and their increased fragility. In order to minimize this already increased risk, adequate triage is of foremost importance for fragile geriatric (>75 years old) patients who present to the ED. The admissions of elderly patients from 1 January 2014 to 31 December 2020 were examined, taking into consideration the presence of two different triage systems, a 4-level (4LT) and a 5-level (5LT) triage system. This study analyzes the difference in wait times and under- (UT) and over-triage (OT) in geriatric and general populations with two different triage models. Another outcome of this study was the analysis of the impact of crowding and its variables on the triage system during the COVID-19 pandemic. A total of 423,257 ED presentations were included. An increase in admissions of geriatric, more fragile, and seriously ill individuals was observed, and a progressive increase in crowding was simultaneously detected. Geriatric patients, when presenting to the emergency department, are subject to the problems of UT and OT in both a 4LT system and a 5LT system. Several indicators and variables of crowding increased, with a net increase in throughput and output factors, notably the length of stay (LOS), exit block, boarding, and processing times. This in turn led to an increase in wait times and an increase in UT in the geriatric population. It has indeed been shown that an increase in crowding results in an increased risk of UT, and this is especially true for 4LT compared to 5LT systems. When observing the pandemic period, an increase in admissions of older and more serious patients was observed. However, in the pandemic period, a general reduction in waiting times was observed, as well as an increase in crowding indices and intrahospital mortality. This study demonstrates how introducing a 5LT system enables better flow and patient care in an ED. Avoiding UT of geriatric patients, however, remains a challenge in EDs.

National analysis of over and under-triage rates in relation to trauma population risk factors and associated outcomes across various levels trauma centers

INTRODUCTION

Over and under-triage represent a misallocation of resources that can affect patient outcomes. The purpose of this study is to evaluate over and under-triage rates in relation to risk factors and associated outcomes of trauma patients nationwide.

METHODS

A retrospective cohort study using the Trauma Quality Improvement Program from 2017 to 2020. Multivariable regression models were used to assess predictors of over-triage (activation when unnecessary) and under-triage (limited activation when full activation was necessary).

RESULTS

22.2 % (32,782) of the study population were over-triaged and 20.3 % (29,996) were under-triaged. Most over-triaged patients were Black, with Medicaid, or had a penetrating injury, whereas most under-triaged patients were White, with private/commercial insurance, or had a blunt injury. With covariates adjusted for, Pacific Islander (p = 0.024) and American Indian patients (p = 0.015) were associated with higher odds of over-triage, and Hispanic patients had higher odds of under-triage (p<0.001). Patients with Medicare (p<0.001) had higher odds of over-triage, and patients with private/commercial insurance (p<0.001) had higher odds of under-triage compared to Medicaid patients. Patients in level II (p<0.001) and level III (p<0.001) trauma hospitals were associated with higher odds of over-triage.

CONCLUSION

Pacific Islander and American Indian patients, Medicare, and level II and III trauma centers are at increased risk of over-triage rates, while Hispanic and privately insured trauma patients had a higher risk for under-triage. Future studies should further investigate factors contributing to poor outcomes linked to under-triage practices and methods to improve consistency and standardization of triage tools across various levels of trauma centers.

Assessing Physiologic Reserve and Frailty in the Older Emergency Department Patient: Should the Paradigm Change?

Older patients are more vulnerable to acute illness or injury because of reduced physiologic reserve associated with aging. Therefore, their assessment in the emergency department (ED) should include not only vital signs and their baseline values but also changes that reflect physiologic reserve, such as mobility, mental status, and frailty. Combining aggregated vitals sign scores and frailty might improve risk stratification in the ED. Implementing these changes in ED assessment may require the introduction of senior-friendly processes to ensure ED treatment is appropriate to the older patients' immediate discomfort, personal goals, and likely prognosis.

Evaluating the effects of triage education on triage accuracy within the emergency department: An integrative review

INTRODUCTION

Triage accuracy can affect patient outcomes. Education to ensure nurses provide the most accurate triage scores is paramount for patient safety.The objective was to investigate whether ongoing triage education increases triage accuracy, knowledge or behaviour.

METHOD

An integrative review was conducted by searching five databases to identify studies that included triage-based education. A systematic search strategy was completed followed by analysis with critical appraisal using the Critical Appraisal Skills Programme, a TIDieR Checklist and thematic analysis.

FINDINGS

Four thousand five hundred seventy-six studies were retrieved, with 34 studies selected for inclusion. Thirty-one studies were quantitative, and three were mixed methods. 18 out of 34 studies showed improvement in triage accuracy. Seven showed increased knowledge. Six studies showed no improvement in triage accuracy. Sixteen studies assessed triage behaviour and showed improvement post-intervention, with five showing no changes. Only three studies compared interventions. Fifty-three opportunities for changes to triage accuracy, knowledge or behaviour were found, 41 showed improvements.

CONCLUSION

Triage education interventions can improve accuracy, knowledge and behaviour, but whether improvements are sustained needs further research.

Emergency Severity Index (ESI) algorithm in trauma patients: The impact of age during the pandemic

OBJECTIVE

The ESI algorithm is widely used to triage patients in the emergency room. However, few studies have assessed the reliability of ESI to accurately triage trauma patients. The aim of this study was to compare vital signs, resource utilization, and patient outcomes among trauma patients during the pandemic in 2020 vs. the previous year prior to the pandemic.

METHODS

This retrospective study was conducted over a 24-month period at an urban adult level one trauma center. Demographic and clinical characteristics, resource utilization, and patient outcomes were extracted from the electronic medical records and trauma registry. Trauma patients assigned ESI level 2 were stratified by age (<65 years and ≥ 65 years) and year (2019 vs. 2020) for data analysis.

RESULTS

A total of 3,788 trauma patients were included in the study. Males represented 68.4% (2,591) of patients and the median age was 50 years (IQR: 31, 69). The majority of patients were assigned ESI level 2 (2,162, 57.1%) and had a blunt mechanism of injury (3,122, 82.4%). In 2020, patients <65 years of age utilized less resources compared to 2019 (p < 0.001). Likewise, patients >65 years of age required less lab tests [OR: 0.1, 95% CI: (0.05 - 0.4)], IV fluids [OR: 0.2, 95% CI: (0.2 -0.3)], IV medications [OR: 0.6, 95% CI: (0.4 - 0.7)], and specialty consultations [OR: 0.4, 95% CI: (0.3 -0.5)] compared to 2019 (p < 0.0001). Within 2020, vital signs and resources utilized between younger and elderly patients varied significantly (p < 0.01). Correspondingly, the clinical outcomes between younger and elderly patients within 2020, differed significantly (p < 0.01).

CONCLUSIONS

The COVID-19 pandemic affected the triage of trauma patients. During 2020, patients utilized less resources compared to the previous year. Additionally, younger and elderly patients had different vital signs, resource utilization, and clinical outcomes although both being assigned ESI level 2. Younger trauma patients may have been over-triaged in 2020 due to the COVID-19 pandemic.

Prehospital triage in emergency medical services system: A scoping review

BACKGROUND

During the prehospital phase, paramedics consider patients' condition according to illness, injury, disease and decide on transport to an appropriate hospital according to severity. This can affect patient survival and treatment prognosis, because despite intervention at this early stage, problems such as incorrect triage of severity and inappropriate hospital selection may occur, indicating a need for improvement in the process.

PURPOSE

The aim of this review is to identify the overall trend of research conducted on prehospital triage by analyzing the emergency medical services system and presenting future studies to practitioners and researchers.

METHODS

A scoping review was conducted of existing literature on research trends in relation to prehospital triage. The studies reviewed were identified using electronic databases such as PubMed, CINAHL, Cochrane Library, Web of Science, and Scopus.

RESULTS

Ninety-eight documents were finally selected and analyzed that focused on prehospital triage status, process accuracy, tools, guidelines, and protocols.

CONCLUSION

Research is proposed that focuses on various non-traumatic patient types, prehospital triage education, and development of training programs to reduce errors in the emergency patient handover process between prehospital and hospital health professionals and to improve patient health and quality of life.

Throughput delays: causes, predictors, and outcomes - observational cohort in a Swiss emergency department

BACKGROUND

Optimal throughput times in emergency departments can be adjudicated by emergency physicians. Emergency physicians can also define causes of delays during work-up, such as waiting for imaging, clinical chemistry, consultations, or exit blocks. For adequate streaming, the identification of predictors of delays is important, as the attribution of resources depends on acuity, resources, and expected throughput times.

OBJECTIVE

This observational study aimed to identify the causes, predictors, and outcomes of emergency physician-adjudicated throughput delays.

METHODS

Two prospective emergency department cohorts from January to February 2017 and from March to May 2019 around the clock in a tertiary care centre in Switzerland were investigated. All consenting patients were included. Delay was defined as the subjective adjudication of the responsible emergency physician regarding delay during emergency department work-up. Emergency physicians were interviewed for the occurrence and cause of delays. Baseline demographics, predictor values, and outcomes were recorded. The primary outcome - delay - was presented using descriptive statistics. Univariable and multivariable logistic regression analyses were performed to assess the associations between possible predictors and delays and hospitalization, intensive care, and death with delay.

RESULTS

In 3656 (37.3%) of 9818 patients, delays were adjudicated. The patients with delays were older (59 years, interquartile range [IQR]: 39-76 years vs 49 years, IQR: 33-68 years) and more likely had impaired mobility, nonspecific complaints (weakness or fatigue), and frailty than the patients without delays. The main causes of delays were resident work-up (20.4%), consultations (20.2%), and imaging (19.4%). The predictors of delays were an Emergency Severity Index of 2 or 3 at triage (odds ratio [OR]: 3.00; confidence interval [CI]: 2.21-4.16; OR: 3.25; CI: 2.40-4.48), nonspecific complaints (OR: 1.70; CI: 1.41-2.04), and consultation and imaging (OR: 2.89; CI: 2.62-3.19). The patients with delays had an increased risk for admission (OR: 1.56; CI: 1.41-1.73) but not for mortality than those without delays.

CONCLUSION

At triage, simple predictors such as age, immobility, nonspecific complaints, and frailty may help to identify patients at risk of delay, with the main reasons being resident work-up, imaging, and consultations. This hypothesis-generating observation will allow the design of studies aimed at the identification and elimination of possible throughput obstacles.

Training nurses to triage: a scoping review

Triage accuracy is important to ensure effective treatment and management of patients in the emergency department, however this requires nurses to receive high-quality triage training. This article reports the results of a scoping review that aimed to establish what research on triage training exists and what research is required to improve such training. Sixty-eight studies which used a range of training interventions and outcome measurements were reviewed. The authors conclude that the heterogeneity of these studies makes comparison challenging and that this, combined with low methodological quality, requires caution when applying the results in practice. The authors recommend establishing a gold standard for measuring triage training outcomes.

Older Adults, the "Social Admission," and Nonspecific Complaints in the Emergency Department: Protocol for a Scoping Review

BACKGROUND

Older adults have a higher visit rate and poorer health outcomes in the emergency department (ED) compared to their younger counterparts. Older adults are more likely to require additional resources and hospital admission. The nonspecific, atypical, and complex nature of disease presentation in older adults challenges current ED triage systems. Acute illness in older adults is often missed or commonly disguised in the ED as a social or functional issue. If diagnostic clarity is lacking or safe discharge from the ED is not feasible, then older adults may be labelled a "social admission" (or another synonymous term), often leading to negative health consequences.

OBJECTIVE

This scoping review aims to describe and synthesize the available evidence on patient characteristics, adverse events, and health outcomes for older adults labelled as "social admission" (and other synonymously used terms), as well as those with nonacute or nonspecific complaints in the ED or hospital setting.

METHODS

A literature search of MEDLINE, Embase, Scopus, PsycINFO, and CINAHL was completed. Relevant reference lists were screened. Data have been managed using EndNote software and the Covidence web application. Original data have been included if patients are aged ≥65 years and are considered a "social admission" (or other synonymously used term) or if they present to the ED with a nonacute or nonspecific complaint. Two review team members have reviewed titles and abstracts and will review full-text articles. Disagreements are resolved by consensus or in discussion with a third reviewer. This review does not require research ethics approval.

RESULTS

As of January 2023, we have completed the title and abstract screening and have started the full-text screening. Some remaining full-text articles are being retrieved and/or translated. We are extracting data from included studies. Data will be presented in a narrative and descriptive manner, summarizing key concepts, patient characteristics, and health outcomes of patients labelled as a "social admission" (and other synonymously used terms) and of those with nonacute and nonspecific complaints. We expect the first results for publication in Spring 2023.

CONCLUSIONS

Acute illness in the older adult is not always easily identified. We hope to better understand patient characteristics, adverse events, and health outcomes of older adults labelled as a "social admission," as well as those with nonacute or nonspecific complaints. We aim to identify priorities for future research and identify knowledge gaps that may inform health care providers caring for these vulnerable patients.

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.

Clinical Frailty Scale as a predictor of short-term mortality: A systematic review and meta-analysis of studies on diagnostic test accuracy

BACKGROUND

The Clinical Frailty Scale (CFS) is a representative frailty assessment tool in medicine. This systematic review and meta-analysis aimed to examine whether frailty defined based on the CFS could adequately predict short-term mortality in emergency department (ED) patients.

METHODS

The PubMed, EMBASE, and Cochrane libraries were searched for eligible studies until December 23, 2021. We included studies in which frailty was measured by the CFS and short-term mortality was reported for ED patients. All studies were screened by two independent researchers. Sensitivity, specificity, positive likelihood ratio (PLR), and negative likelihood ratio (NLR) values were calculated based on the data extracted from each study. Additionally, the diagnostic odds ratio (DOR) was calculated for effect size analysis, and the area under the curve (AUC) of summary receiver operating characteristics was calculated. Outcomes were in-hospital and 1-month mortality rate for patients with the CFS scores of ≥5, ≥6, and ≥7.

RESULTS

Overall, 17 studies (n = 45,022) were included. Although there was no evidence of publication bias, a high degree of heterogeneity was observed. For the CFS score of ≥5, the PLR, NLR, and DOR values for in-hospital mortality were 1.446 (95% confidence interval [CI] 1.325-1.578), 0.563 (95% CI 0.355-0.893), and 2.728 (95% CI 1.872-3.976), respectively. In addition, the pooled statistics for 1-month mortality were 1.566 (95% CI 1.241-1.976), 0.582 (95% CI 0.430-0.789), and 2.696 (95% CI 1.673-4.345), respectively. Subgroup analysis of trauma patients revealed that the CFS score of ≥5 could adequately predict in-hospital mortality (PLR 1.641, 95% CI 1.242-2.170; NLR 0.580, 95% CI 0.461-0.729; DOR 2.883, 95% CI 1.994-4.168). The AUC values represented sufficient to good diagnostic accuracy.

CONCLUSIONS

Evidence that is published to date suggests that the CFS is an accurate and reliable tool for predicting short-term mortality in emergency patients.

Time to CT scan for patients with acute severe neurological symptoms: a quality assurance study

Emergent brain computed tomography (CT) scan allows for identification of patients presenting with acute severe neurological symptoms in whom medical and surgical interventions may be lifesaving. The aim of this study was to evaluate if time to CT from arrival at the emergency department exceeded 30 min in patients admitted with acute severe neurological symptoms. This was a retrospective register-based quality assurance study. We identified patients admitted to the emergency department with acute severe neurological symptoms between April 1st, 2016 and September 30th, 2020. Data were retrieved from the registry of acute medical team activations. We considered that time to CT from arrival at the emergency department should not exceed 30 min in more than 10% of patients. A total of 559 patients were included. Median time from arrival at the emergency department until CT scan was 24 min (IQR 16–35) in children (< 18 years), 10 min (IQR 7–17) for adults (18–59 years), and 11 min (IQR 7–16) for elders (> 60 years). This time interval exceeded 30 min for 8.2% (95% CI 6.1–10.9) of all included patients, 35.3% of children, 5.9% of adults, and 8.6% of elders. No children died within 30 days. The 30-day mortality was 21.3% (95% CI 16.4–27) in adults, and 43.9% (95% CI 38.2–49.8) in elders. Time from arrival at our emergency department until brain CT scan exceeded 30 min in 8.2% of all included patients but exceeded the defined quality aim in children and could be improved.

Identification through the Manchester Triage System of the older population at risk of delirium: A case-control study

OBJECTIVE

To identify the flow charts and discriminators of the Manchester Triage System that are most likely to identify the onset of delirium in older people.

BACKGROUND

Delirium is an underdiagnosed geriatric syndrome, and up to 80% of all cases of delirium go undetected in emergency departments. Patient triage seeks to manage clinical risk with a view to safely and appropriately managing patient flows.

DESIGN

A case-control study was performed according to the STROBE checklist.

SETTING

The emergency department of a secondary hospital.

PARTICIPANTS

Older adults aged ≥65 years and admitted from 1 January to 31 December 2020.

METHODS

Older patients were identified from the emergency department research database. Cases were defined as patients diagnosed with delirium (n = 128), excluding cases of delirium due to alcohol or substance abuse. Controls were randomised from the remaining patients (n = 128).

RESULTS

A total of 29.35% of the subjects admitted to the emergency department were older adults with an incidence of delirium of 0.7%. The flow charts with the highest probability of delirium were 'unwell adult' [OR = 3.04 (95%CI:1.82-5.1)] and 'behaving strangely' [OR = 16.06 (95%CI:3.72-69.29)], and the discriminators were 'rapid onset' [OR = 3.3 (95%CI:1.85-5.88)] and 'new neurological deficit less than 24 h old' [OR = 4.76 (95%%CI:1.01-22.5). The area under the curve for 'unwell adult' in the presence of dementia, previous stroke and fall in the previous 30 days was 0.73 (95%CI: 0.67-0.79), and that for 'behaving strangely' in the presence of diabetes was 0.75 (95%CI: 0.69-0.81).

CONCLUSIONS

Knowing which flow charts, discriminators and risk factors are most likely to predict delirium allows the identification of the older population at risk for triage screening in emergency departments.

RELEVANCE TO CLINICAL PRACTICE

Risk factors such as diabetes, dementia, previous stroke and recent fall among 'unwell adult' or 'behaving strangely' triaged older persons should be assessed for the probable presence of delirium.

Evaluation and disposition of older adults presenting to the emergency department with abdominal pain

BACKGROUND

Abdominal pain is the most common chief complaint in US emergency departments (EDs) among patients over 65, who are at high risk of mortality or incident disability after the ED encounter. We sought to characterize the evaluation, management, and disposition of older adults who present to the ED with abdominal pain.

METHODS

We performed a survey-weighted analysis of the National Hospital Ambulatory Medical Care Survey (NHAMCS), comparing older adults with a chief complaint of abdominal pain to those without. Visits from 2013 to 2017 to nationally representative EDs were included. We analyzed 81,509 visits to 1211 US EDs, which projects to 531,780,629 ED visits after survey weighting. We report the diagnostic testing, evaluation, management, additional reasons for visit, and disposition of ED visits.

RESULTS

Among older adults (≥65 years), 7% of ED visits were for abdominal pain. Older patients with abdominal pain had a lower probability of being triaged to the "Emergent" (ESI2) acuity on arrival (7.1% vs. 14.8%) yet were more likely to be admitted directly to the operating room than older adults without abdominal pain (3.6% vs. 0.8%), with no statistically significant differences in discharge home, death, or admission to critical care. Ultrasound or CT imaging was performed in 60% of older adults with abdominal pain. A minority (39%) of older patients with abdominal pain received an electrocardiogram (EKG).

CONCLUSIONS

Abdominal pain in older adults presenting to EDs is a serious condition yet is triaged to "emergent" acuity at half the rate of other conditions. Opportunities for improving diagnosis and management may exist. Further research is needed to examine whether improved recognition of abdominal pain as a syndromic presentation would improve patient outcomes.

Assessment of patient mobility improves the risk stratification of triage with the Emergency Severity Index: a prospective cohort study

BACKGROUND AND IMPORTANCE

Formal triage may assign a low acuity to patients at high risk of deterioration and mortality. A patient's mobility can be easily assessed at triage.

OBJECTIVE

To investigate if a simple assessment of mobility at triage can improve the Emergency Severity Index's (ESI) prediction of adverse outcomes.

DESIGN, SETTING AND PARTICIPANTS

Prospective observational study of all patients attending the emergency department (ED) of a single academic hospital in Switzerland over a period of 3 weeks.

OUTCOME MEASURES AND ANALYSIS

Triage clinicians classified participants as having normal or impaired mobility at triage. Impaired mobility was defined as the lack of a stable independent gait, regardless of its cause or duration (e.g. any patient who needed help to walk). The primary outcome was 30-day mortality. We performed a survival analysis stratified by mobility and ESI level. We compared the performance of regression models including the ESI alone or in combination with mobility as predictors of mortality using the Bayesian information criterion (BIC).

MAIN RESULTS

2523 patients were included in the study and 880 (34.9%) had impaired mobility. Patients with impaired mobility had a lower median 30-day survival in ESI levels 1-3. Survival of patients with normal mobility was similar regardless of their ESI level.

CONCLUSION

The assessment of mobility at triage improves the ESI algorithm's risk stratification.

Ability of prehospital NEWS to predict 1-day and 7-day mortality is reduced in the older adult patients

BACKGROUND

National Early Warning Score (NEWS) does not include age as a parameter despite age is a significant independent risk factor of death. The aim of this study was to examine whether age has an effect on predictive performance of short-term mortality of NEWS in a prehospital setting. We also evaluated whether adding age as an additional parameter to NEWS improved its short-term mortality prediction.

METHODS

We calculated NEWS scores from retrospective prehospital electronic patient record data for patients 18 years or older with sufficient prehospital data to calculate NEWS. We used area under receiver operating characteristic (AUROC) to analyse the predictive performance of NEWS for 1 and 7 day mortalities with increasing age in three different age groups: <65 years, 65-79 years and ≥80 years. We also explored the ORs for mortality of different NEWS parameters in these age groups. We added age to NEWS as an additional parameter and evaluated its effect on predictive performance.

RESULTS

We analysed data from 35 800 ambulance calls. Predictive performance for 7-day mortality of NEWS decreased with increasing age: AUROC (95% CI) for 1-day mortality was 0.876 (0.848 to 0.904), 0.824 (0.794 to 0.854) and 0.820 (0.788 to 0.852) for first, second and third age groups, respectively. AUROC for 7-day mortality had a similar trend. Addition of age as an additional parameter to NEWS improved its ability to predict short-term mortality when assessed with continuous Net Reclassification Improvement.

CONCLUSIONS

Age should be considered as an additional parameter to NEWS, as it improved its performance in predicting short-term mortality in this prehospital cohort.

Factors associated with the undertriage of patients with abdominal pain in an emergency room

INTRODUCTION

The triage process lasts for a very short time, which can result in over-triage and under-triage. Studies have explored factors related to under-triage among trauma patients. In Korea, the clinical characteristics and severity of cases of under-triaged patients have been investigated. However, there is limited research on the under-triage of patients experiencing abdominal pain. Therefore, this study aimed to determine the under-triage rate of emergency department (ED) patients with abdominal pain, as well as the factors associated with their under-triage.

METHODS

The participants of this retrospective cohort study were 3,030 adult patients at a single tertiary hospital in Korea, who were brought to the ED for abdominal pain as the chief complaint. Participants' general characteristics, pain-related information, and environmental information were obtained from their electronic medical records.

RESULTS

The under-triage rate of ED patients with abdominal pain was 31.0%. Factors related to the under-triage of these patients were sex, age, visit route, time from the onset of the pain to the visit, location of pain, and intensity of pain.

CONCLUSION

These findings provide a foundation for the understanding and mitigation of under-triage in EDs through the identification of factors associated with under-triage in patients with abdominal pain.

[Information technology and eHealth to improve patient safety]

Patient safety is a key element of high-quality healthcare. Digitalization, new eHealth applications and data-based algorithms have high potential to make a significant contribution. This article presents current technological developments along a simplified patient journey from emergency medical triage, diagnosis and therapy to follow-up. The technical interventions are highly diverse and mostly accompanied by a low level of evidence, since most of them are from single academic projects or start-ups. Although there should be no doubt that technology is an important instrument for increasing patient safety, new technologies also involve new risks. Furthermore, technical measures must always be embedded in an overall concept of organizational measures, adequate education, training and accompanying research in order to generate the highest possible benefits and lowest possible risks.

Physicians' Disease Severity Ratings are Non-Inferior to the Emergency Severity Index

Our objective was to compare informal physicians’ disease severity ratings (PDSR) at presentation with the well-established Emergency Severity Index (ESI) in order to test for non-inferiority of the discriminatory ability regarding hospitalization, intensive care, and mortality. We made a prospective observational study with consecutive enrollment. At presentation, the PDSR and subsequently Emergency Severity Index (ESI) levels were recorded. The primary outcome was the non-inferiority of the discriminatory ability (PDSR versus ESI) regarding hospitalization, intensive care, and mortality. The secondary outcomes were the reliability, the predictive validity, and the safety of PDSR. We included 6859 patients. The median age was 51 years (interquartile range (IQR) = 33 to 72 years); 51.4% were males. There were 159 non-survivors (2.4%) at the 30 day follow-up. The PDSR’s discriminatory ability was non-inferior to the ESI’s discriminatory ability. The safety assessment showed mortality of <0.5% in low-acuity patients in both tools. The predictive validity increased by 3.5 to 7 times if adding high-acuity PDSR to ESI in all categories with mortality of >1%. Our data showed the non-inferiority of PDSR compared with ESI regarding discriminatory ability, a moderate reliability, and an acceptable safety of both tools.

Prevalence of Fractures and Diagnostic Accuracy of Emergency X-ray in Older Adults Sustaining a Low-Energy Fall: A Retrospective Study

BACKGROUND

Plain radiography (XR) series are standard of care for detection of fall-related fractures in older patients with low-energy falls (LEF) in the emergency department (ED). We have investigated the prevalence of fractures and diagnostic accuracy of XR imaging in the ED.

METHODS

2839 patients with LEF, who were presented to two urban level I trauma centers in 2016 and received XR and computed tomography (CT), were consecutively included in this retrospective cohort study. The primary endpoint was the prevalence of fractures of the vertebral column, rib cage, pelvic ring, and proximal long bones. Secondary endpoints were diagnostic accuracy of XR for fracture detection with CT as reference standard and cumulative radiation doses applied.

RESULTS

Median age was 82 years (range 65-105) with 64.1% female patients. Results revealed that 585/2839 (20.6%) patients sustained fractures and 452/2839 (15.9%) patients received subsequent XR and CT examinations of single body regions. Cross-tabulation analysis revealed sensitivity of XR of 49.7%, a positive likelihood ratio of 27.6, and negative likelihood ratio of 0.5.

CONCLUSIONS

XR is of moderate diagnostic accuracy for ruling-out fractures of the spine, pelvic ring, and rib cage in older patients with LEF. Prospective validations are required to investigate the overall risk-benefit of direct CT imaging strategies, considering the trade-off between diagnostic safety, health care costs, and radiation exposure.

Modification of the Emergency Severity Index Improves Mortality Prediction in Older Patients

Introduction

Older patients frequently present to the emergency department (ED) with nonspecific complaints (NSC), such as generalized weakness. They are at risk of adverse outcomes, and early risk stratification is crucial. Triage using Emergency Severity Index (ESI) is reliable and valid, but older patients are prone to undertriage, most often at decision point D. The aim of this study was to assess the predictive power of additional clinical parameters in NSC patients.

Methods

Baseline demographics, vital signs, and deterioration of activity of daily living (ADL) in patients with NSC were prospectively assessed at four EDs. Physicians scored the coherence of history and their first impression. For prediction of 30-day mortality, we combined vital signs at decision point D (heart rate, respiratory rate, oxygen saturation) as “ESI vital,” and added “ADL deterioration,” “incoherence of history,” or “first impression,” using logistic regression models.

Results

We included 948 patients with a median age of 81 years, 62% of whom were female. The baseline parameters at decision point D (ESI vital) showed an area under the curve (AUC) of 0.64 for predicting 30-day mortality in NSC patients. AUCs increased to 0.67 by adding ADL deterioration to 0.66 by adding incoherence of history, and to 0.71 by adding first impression. Maximal AUC was 0.73, combining all parameters.

Conclusion

Adding the physicians’ first impressions to vital signs at decision point D increases predictive power of 30-day mortality significantly. Therefore, a modified ESI could improve predictive power of triage in older patients presenting with NSCs.

Comparison between Emergency Severity Index plus peak flow meter and Emergency Severity Index in the dyspneic patients with chronic obstructive pulmonary disease: A randomized clinical trial

Introduction

It is unclear whether the Emergency Severity Index (ESI) can identify high-risk patients with Chronic Obstructive Pulmonary Disease (COPD). This study aims to compare the mistriage rates of the ESI plus the Peak Expiratory Flowmeter (PEF) approach and ESI approach among dyspneic patients with COPD.

Methods

This study was a randomized clinical trial conducted between July and October 2018. We randomly assigned COPD patients with dyspnea to the ESI + PEF or ESI groups. Triage levels, disposition rates, number of resources used, and time to first physician contact were compared in patients admitted to the Intensive Care Unit (ICU), the Pulmonary Care Unit (PU), or discharged from the ED. Reliability of the ESI was evaluated by using the interobserver agreement (Kappa).

Results

Seventy COPD patients were equally assigned to the ESI + PEF and ESI groups. The under-triage rates were 11.42% and 0%, the over-triage rates were 31.42% and 2.85% in the ESI and ESI + PEF groups, respectively. The triage levels of the patients admitted to the ICU (2 vs. 3), the PU (2 vs. 4), or discharged from the ED (3 vs. 2) were significantly different between the ESI + PEF and ESI groups.

Conclusions

Addition of PEF to the ESI provides a more accurate method for triaging COPD patients compared to ESI alone. We recommend using PEF for the triage of COPD patients in the ED.

Study protocol for a multicentre prospective cohort study to identify predictors of adverse outcome in older medical emergency department patients (the Risk Stratification in the Emergency Department in Acutely Ill Older Patients (RISE UP) study)

BACKGROUND

Older patients (≥65 years old) experience high rates of adverse outcomes after an emergency department (ED) visit. Reliable tools to predict adverse outcomes in this population are lacking. This manuscript comprises a study protocol for the Risk Stratification in the Emergency Department in Acutely Ill Older Patients (RISE UP) study that aims to identify predictors of adverse outcome (including triage- and risk stratification scores) and intends to design a feasible prediction model for older patients that can be used in the ED.

METHODS

The RISE UP study is a prospective observational multicentre cohort study in older (≥65 years of age) ED patients treated by internists or gastroenterologists in Zuyderland Medical Centre and Maastricht University Medical Centre+ in the Netherlands. After obtaining informed consent, patients characteristics, vital signs, functional status and routine laboratory tests will be retrieved. In addition, disease perception questionnaires will be filled out by patients or their caregivers and clinical impression questionnaires by nurses and physicians. Moreover, both arterial and venous blood samples will be taken in order to determine additional biomarkers. The discriminatory value of triage- and risk stratification scores, clinical impression scores and laboratory tests will be evaluated. Univariable logistic regression will be used to identify predictors of adverse outcomes. With these data we intend to develop a clinical prediction model for 30-day mortality using multivariable logistic regression. This model will be validated in an external cohort. Our primary endpoint is 30-day all-cause mortality. The secondary (composite) endpoint consist of 30-day mortality, length of hospital stay, admission to intensive- or medium care units, readmission and loss of independent living. Patients will be followed up for at least 30 days and, if possible, for one year.

DISCUSSION

In this study, we will retrieve a broad range of data concerning adverse outcomes in older patients visiting the ED with medical problems. We intend to develop a clinical tool for identification of older patients at risk of adverse outcomes that is feasible for use in the ED, in order to improve clinical decision making and medical care.

TRIAL REGISTRATION

Retrospectively registered on clinicaltrials.gov ( NCT02946398 ; 9/20/2016).

Camera-based measurement of respiratory rates is reliable

OBJECTIVES

Respiratory rate (RR) is one of the most important vital signs used to detect whether a patient is in critical condition. It is part of many risk scores and its measurement is essential for triage of patients in emergency departments. It is often not recorded as measurement is cumbersome and time-consuming. We intended to evaluate the accuracy of camera-based measurements as an alternative measurement to the current practice of manual counting.

MATERIALS AND METHODS

We monitored the RR of healthy male volunteers with a camera-based prototype application and simultaneously by manual counting and by capnography, which was considered the gold standard. The four assessors were mutually blinded. We simulated normoventilation, hypoventilation and hyperventilation as well as deep, normal and superficial breathing depths to assess potential clinical settings. The volunteers were assessed while being undressed, wearing a T-shirt or a winter coat.

RESULTS

In total, 20 volunteers were included. The results of camera-based measurements of RRs and capnography were in close agreement throughout all clothing styles and respiratory patterns (Pearson's correlation coefficient, r=0.90-1.00, except for one scenario, in which the volunteer breathed slowly dressed in a winter coat r=0.84). In the winter-coat scenarios, the camera-based prototype application was superior to human counters.

CONCLUSION

In our pilot study, we found that camera-based measurements delivered accurate and reliable results. Future studies need to show that camera-based measurements are a secure alternative for measuring RRs in clinical settings as well.

Short-term mortality in older medical emergency patients can be predicted using clinical intuition: A prospective study

Background

Older emergency department (ED) patients are at risk for adverse outcomes, however, it is hard to predict these. We aimed to assess the discriminatory value of clinical intuition, operationalized as disease perception, self-rated health and first clinical impression, including the 30-day surprise question (SQ: “Would I be surprised if this patient died in the next 30 days” of patients, nurses and physicians. Endpoints used to evaluate the discriminatory value of clinical intuition were short-term (30-day) mortality and other adverse outcomes (intensive/medium care admission, prolonged length of hospital stay, loss of independent living or 30-day readmission).

Methods

In this prospective, multicentre cohort study, older medical patients (≥65 years), nurses and physicians filled in scores regarding severity of illness and their concerns (i.e. disease perception and clinical impression scores) immediately after arrival of the patient in the ED. In addition, patients filled in a self-rated health score and nurses and physicians answered the SQ. Area under the curves (AUCs) of receiver operating characteristics (ROCs) were calculated.

Results

The median age of the 602 included patients was 79 years and 86.7% were community dwelling. Within 30 days, 66 (11.0%) patients died and 263 (43.7%) patients met the composite endpoint. The severity of concern score of both nurses and physicians yielded the highest AUCs for 30-day mortality (for both 0.75; 95%CI 0.68–0.81). AUCs for the severity of illness score and SQ of nurses and physicians ranged from 0.71 to 0.74 while those for the disease perception and self-rated health of patients ranged from 0.64 to 0.69. The discriminatory value of the scores for the composite endpoint was lower (AUCs ranging from 0.60 to 0.67). We used scores that have not been previously validated which could influence their generalisability.

Conclusion

Clinical intuition,—disease perception, self-rated health and first clinical impression—documented at an early stage after arrival in the ED, is a useful clinical tool to predict mortality and other adverse outcomes in older ED patients. Highest discriminatory values were found for the nurses’ and physicians’ severity of concern score. Intuition may be helpful for the implementation of personalised medical care in the future.

Responsibility-Evading Performance: The Experiences of Healthcare Staff about Triage in Emergency Departments: A Qualitative Study

Background:

Correct triage is one of the most important issues in delivering proper healthcare in the emergency department. Despite the availability of various triage guidelines, triage is not still appropriately implemented. Therefore, this study was conducted to investigate the role of different underlying factors in triaging emergency patients through a qualitative approach.

Materials and Methods:

This study was conducted by conventional content analysis. For this purpose, 30 interviews were conducted with 25 participants. The participants included triage nurses, emergency general physicians, emergency medicine specialists, and expert managers at different position rankings in hospitals and educational and administrative centers in Yazd, selected by purposeful sampling. Data were collected through in-depth and unstructured interviews from April 2017 to January 2018, and then analyzed by inductive content analysis.

Results:

Four categories of profit triage, exhibitive triage, enigmatic, and tentative performance triage were drawn from the data, collectively comprising the main theme of responsibility-evading performance.

Conclusions:

The dominant approach to the triage in the emergency departments in a central city of Iran is responsibility evasion; however, the triage is performed tentatively, especially in critical cases. To achieve a better implementation of triage, consideration of the underlying factors and prevention of their involvement in triage decision-making is necessary.

Ten Best Practices for the Older Patient in the Emergency Department

This article reviews 10 best practices that integrate geriatric principles into emergency department processes of care. These best practices are grouped around ten words: complexity; clinician education; geriatric-specific; atypical; medication; variability; cognitive impairment; psychosocial issues; end-of-life care; and interdisciplinary.

An Approach to the Older Patient in the Emergency Department

Older patients in the emergency department (ED) present unique diagnostic and therapeutic challenges. The ED clinicians must simultaneously evaluate and treat older adults along multiple domains: cognitive impairment, atypical presentations, functional impairment, medication management, trauma and falls, and end-of-life care. This article reviews these domains and suggests strategies for a more comprehensive, patient-centered ED approach to older patients. Incorporating assessment of these domains into the ED process improves patient outcomes, provider satisfaction, and ED flow.

Elderly care in the emergency department: an integrative review

Abstract Objective: To identify the care practices of nurses for the elderly in emergency departments. Method: An integrative review was carried out in the CAPES database, selecting publications in English, Portuguese and Spanish published between January 2011 and October 2016. The descriptors used were: "Emergency nursing"; "Geriatric nursing"; "Health services for the elderly"; "Elderly person"; "Nursing care". Results: Sixteen articles were analyzed in English, the majority of which had a qualitative approach (56.2%). Australia had the largest number of publications (31.2%). After reading the studies in full, the common themes were organized and classified into three categories: Challenges/difficulties in the care of the elderly in the emergency department, Positive experiences of elderly care in the emergency department and The emergency department as a space of death and dying. Conclusion: The care practices of nurses are focused on identifying the main problems regarding elderly care, adaptation and the planning of their work routine. Another strategy is the implementation of instruments of evaluation specific to elderly patients and the involvement of the family in all stages of care.

Emergency Department Length of Stay for Critical Care Admissions. A Population-based Study

RATIONALE

Hospital emergency department (ED) strain is common in North America. Excessive strain may result in prolonged ED length of stay and may lead to worse outcomes for patients admitted to intensive care units (ICUs).

OBJECTIVES

To describe patient, ED, and hospital characteristics associated with prolonged ED length of stay for adult patients admitted from EDs to ICUs.

METHODS

We conducted a population-based cohort study in the Province of Ontario, Canada, including patients admitted to an adult ICU from an ED and excluding only interhospital transfers and scheduled visits. Using regression modeling, we examined associations between patient- and hospital-level characteristics and two ED performance measures: length of stay in the ED of more than 6 hours and 90-day mortality.

MEASUREMENTS AND MAIN RESULTS

From April 2007 to March 2012, 261,274 adults presented to 118 EDs in Ontario, generating 314,836 ICU admissions. This activity represented 4.1% of all adult ED visits (incidence, 1,374 ICU admissions/100,000 ED visits). Median (interquartile range) ED length of stay was 7 (4-13) hours. Less than half (41.4%; 95% confidence interval [CI], 41.2-41.5) of these patients had an ED length of stay of 6 hours or less, whereas 10.5% (95% CI, 10.4-10.6) stayed 24 hours or longer. Hospital characteristics associated with ED length of stay more than 6 hours included shift-level ED crowding (mean length of stay of patients of similar acuity registering during same 8 h epoch) (odds ratio [OR], 1.19/h; 95% CI, 1.19-1.19), ED annual visit volume (OR, 1.01/1,000 patients; 95% CI, 1.01-1.01), time of ED presentation (00:00-07:59) (OR, 1.41; 95% CI, 1.38-1.45), and ICU functioning at greater than 20% above the average annual census (OR, 1.10; 95% CI, 1.08-1.12). ED length of stay more than 6 hours was not associated with 90-day mortality after adjustment for selected confounders (OR, 0.99; 95% CI, 0.97-1.02).

CONCLUSIONS

In this population-based study, less than half of adult ED patients were admitted to an ICU 6 hours or less after arrival to an ED, an internationally recognized performance indicator for ED care quality. ED and ICU strain generated by time-varying demand on capacity was an important determinant of ED length of stay. However, prolonged length of stay in an ED did not measurably reduce 90-day mortality.

Nursing Perceptions of the Emergency Severity Index as a Triage Tool in the United Arab Emirates: A Qualitative Analysis

INTRODUCTION

With emergency department crowding becoming an increasing problem across the globe, nursing triage to prioritize patients receiving care is ever more important. ESI is the most common triage system used in the United States and is increasingly used worldwide. This qualitative study that explores emergency nursing perceptions of the ESI identifies strengths, weaknesses, and barriers to implementation of the ESI internationally.

METHODS

We conducted a cross-sectional qualitative analysis using semistructured interviews of 27 emergency triage nurses. Content analysis was performed by 2 independent coders, using NVivo software to identify and analyze important themes.

RESULTS

Interview coding revealed 7 core themes related to use of the ESI (frequencies indicated in parentheses): ease of use (90), speed and efficiency (135), patient safety (12), accuracy and reliability (30), challenging patient characteristics (123), subjectivity and variability (173), and effect of triage system on team dynamics (100). Intercoder agreement was excellent (Cohen's unweighted kappa = 0.84). Subjectivity and variability in ESI score assignment consistently emerged in all interviews and included variability in number and use of resources, definition of "high risk," nursing experience, and subjectivity in pain assessment.

DISCUSSION

Although emergency nurses perceive the ESI as easy to use, there are concerns about the subjectivity and variability inherent in the ESI that can lead to a functional lack of triage and a burden of undifferentiated ESI level 3 patients. These limitations in separating critically ill patients and in stratifying patients based on anticipated required resources points to the need for improvement in the ESI algorithm or a more objective triage system that can predict patient outcomes.

Clinical frailty adds to acute illness severity in predicting mortality in hospitalized older adults: An observational study

AIM

Frail individuals may be at higher risk of death from a given acute illness severity (AIS), but this relationship has not been studied in an English National Health Service (NHS) acute hospital setting.

METHODS

This was a retrospective observational study in a large university NHS hospital in England. We analyzed all first non-elective inpatient episodes of people aged ≥75years (all specialties) between October 2014 and October 2015. Pre-admission frailty was assessed with the Clinical Frailty Scale (CFS) of the Canadian Study on Health & Aging, and AIS in the Emergency Department was measured with a Modified Early Warning Score (ED-MEWS<4 was considered as low acuity, and ED-MEWS≥4 as high acuity). A survival analysis compared times to 30-day inpatient death between CFS categories (1-4: very fit to vulnerable, 5: mildly frail, 6: moderately frail, and 7-8: severely or very severely frail).

RESULTS

There were 12,282 non-elective patient episodes (8202 first episodes, of which complete data was available for 5505). In a Cox proportional hazards model controlling for age, gender, Charlson Comorbidity Index, history of dementia, current cognitive concern, and discharging specialty (medical versus surgical), ED-MEWS≥4 (HR=2.87, 95% CI: 2.27-3.62, p<0.001), and CFS 7-8 (compared to CFS 1-4, HR=2.10, 95% CI: 1.52-2.92, p<0.001) were independent predictors of survival time.

CONCLUSIONS

We found frailty and AIS independently associated with inpatient mortality after adjustment for confounders. Hospitals may find it informative to undertake large scale assessment of frailty (vulnerability), as well as AIS (stressor), in older patients admitted to hospital as emergencies.

Nurses' accuracy and self-perceived ability using the Emergency Severity Index triage tool: a cross-sectional study in four Swiss hospitals

Background

The Emergency Severity Index (ESI) is an English language emergency department patient triage tool. After translation, it has been adapted for use to triage patients in growing numbers of emergency departments in non-English-speaking countries. Few reports of the proficiency of triage nurses to score an ESI exist. We sought to determine accuracy, inter-rater reliability, and subjective confidence of triage nurses at four hospitals to determine an ESI from standardized ESI scenarios.

Methods

Triage nurses assigned an ESI score to each of 30 standard ESI (ESI Implementation Handbook Version 4) translated teaching case scenarios. Accuracy and Inter-rater reliability (Krippendorff’s alpha) of the ESI scoring was measured. Nurses’ subjective confidence applying the ESI algorithm was obtained by a Likert scale.

Results

Sixty-nine nurses from four EDs participated in the study. They scored 59.6 % of the case scenarios correctly. Inter-rater reliability was 0.78 (Krippendorff’s alpha). Most (54/69, 78 %) felt confident in their ability to apply the ESI.

Conclusions

Low accuracy of ESI score assignment was observed when nurses scored an ESI for 30 standard written case scenarios, translated into nurses’ native language, despite a good inter-rater reliability and high nurse confidence in their ability to apply the ESI. Although feasible, using standard written case scenarios to determine ESI triage scoring effectiveness may not be the optimum means to rate nurses’ triage skills.

[Recognition of infections in elderly emergency patients]

BACKGROUND

Elderly patients represent an increasing population in the emergency department (ED) and physicians often have to deal with multimorbidity and complexity. Infections are one of the major reasons for ED presentations of older patients and the main cause of mortality; however, infections are often difficult to diagnose in older patients.

AIM

This article provides a review of important indicators for infections, diagnostic tools and limitations in elderly patients.

MATERIAL AND METHODS

A literature search was carried out using PubMed in the period 1990-2015 and in addition own published data are presented.

RESULTS AND CONCLUSION

Infections in the elderly are difficult to assess in the emergency department due to atypical symptoms. Even subtle changes need to be recognized. For the diagnosis of infections in older ED patients unspecific symptoms, vital parameters, laboratory parameters, including C-reactive protein (CRP) and procalcitonin levels, cognitive function and functionality of the patient need to be taken into account.
