The elderly in the emergency department: a critical review of problems and solutions

Impact of dementia on 30-, 180-, and 365-day mortality during the first pandemic wave in older adults seen in spanish emergency departments diagnosed with or without COVID-19

OBJECTIVES

To assess whether dementia is an independent predictor of death after a hospital emergency department (ED) visit by older adults with or without a COVID-19 diagnosis during the first pandemic wave.

METHOD

We used data from the EDEN-Covid (Emergency Department and Elderly Needs during Covid) cohort formed by all patients ≥65 years seen in 52 Spanish EDs from March 30 to April 5, 2020. The association of prior history of dementia with mortality at 30, 180 and 365 d was evaluated in the overall sample and according to a COVID-19 or non COVID diagnosis.

RESULTS

We included 9,770 patients aged 78.7 ± 8.3 years, 51.1% men, 1513 (15.5%) subjects with prior history of dementia and 3055 (31.3%) with COVID-19 diagnosis. 1399 patients (14.3%) died at 30 d, 2008 (20.6%) at 180 days and 2456 (25.1%) at 365 d. The adjusted Hazard Ratio (aHR) for age, sex, comorbidity, disability and diagnosis for death associated with dementia were 1.16 (95% CI 1.01-1.34) at 30 d; 1.15 at 180 d (95% CI 1.03-1.30) and 1.19 at 365 d (95% CI 1.07-1.32), p < .001. In patients with COVID-19, the aHR were 1.26 (95% CI: 1.04-1.52) at 30 days; 1.29 at 180 d (95% CI: 1.09-1.53) and 1.35 at 365 d (95% CI: 1.15-1.58).

CONCLUSION

Dementia in older adults attending Spanish EDs during the first pandemic wave was independently associated with 30-, 180- and 365-day mortality. This impact was lower when adjusted for age, sex, comorbidity and disability, and was greater in patients diagnosed with COVID-19.

Comparison of Manchester, qSOFA, emergency severity index, and national early warning scores for prognostic estimation and effective triage system in geriatric patients

BACKGROUND

Triage refers to classifying and prioritizing patients based on the severity of their injuries or illnesses in the health care setting. The increasing number of elderly patients seeking care in emergency departments (EDs) highlights the need for special attention to the unique needs of this patient population.

AIM

We aimed to compare the qSOFA, Emergency Severity Index (ESI), National Early Warning Score (NEWS), and Manchester Triage System (MTS) scores to assist ED physicians in assessing the severity of elderly patients' clinical conditions and triaging them appropriately.

METHODS

This cross-sectional study included 1066 patients aged 65 and over who presented to our ED as outpatients or by ambulance between September 1, 2022, and August 30, 2023. Scoring systems at the time of admission to the ED were recorded separately for outpatients and arriving by ambulance.

RESULTS

According to the qSOFA, patients with a score of 0 were 0.976 times less likely to arrive by ambulance compared to those scoring 1 and above (OR = 0.976, p = .934). According to the NEWS, patients in the moderate-risk category were 0.447 times less likely to arrive by ambulance (OR = 0.447, p = .054). According to the ESI score, patients requiring high resource use with normal vital signs were 146.758 times more likely to arrive by ambulance (OR = 146.758, p = .001).

CONCLUSION

Significant differences in patients' methods of presentation to the ED were observed based on the MTS, qSOFA, NEWS, and ESI scores.

Optimizing older patient care in emergency departments: a comprehensive survey of current practices and challenges in Northern Italy

BACKGROUND

The progressive aging of the population and the increasing complexity of health issues contribute to a growing number of older individuals seeking emergency care. This study aims to assess the state of the art of care provided to older people in the Emergency Departments of Lombardy, the most populous region in Italy, counting over 2 million people aged 65 years and older.

METHODS

An online cross-sectional survey was developed and disseminated among emergency medicine physicians and physicians affiliated to the Lombardy section of the Italian Society of Geriatrics and Gerontology (SIGG), during June and July 2023. The questionnaire covered hospital profiles, geriatric consultation practices, risk assessment tools, discharge processes and perspectives on geriatric emergency care.

RESULTS

In this mixed method research, 219 structured interviews were collected. The majority of physicians were employed in hospitals, with 54.7% being geriatricians. Critical gaps in older patient's care were identified, including the absence of dedicated care pathways, insufficient awareness of screening tools, and a need for enhanced professional training.

CONCLUSIONS

Tailored protocols and geriatric educational programs are crucial for improving the quality of emergency care provided to older individuals. These measures might also help relieve the burden on the Emergency Departments, thereby potentially enhancing overall efficiency and ensuring better outcomes.

Price for waiting: the adverse outcomes of boarding critically ill elderly medical patients in the emergency department

PURPOSE

Boarding, the period in which a patient spends in the emergency department (ED) before admission, may be hazardous to critically ill patients, particularly the elderly. This study investigated the associations of boarding with hospital course, prognosis, and medical expenditure in older patients.

METHODS

From January 2019 to December 2021, the medical records of older patients (age ≥ 65) visiting the ED of a tertiary referral hospital who were admitted to the medical intensive care unit (ICU) were retrospectively reviewed. Eligible patients were categorized into two groups according to boarding time with a cutoff set at 6 h. Primary outcomes were in-hospital mortality, ICU/hospital length of stay, and total/average hospitalization cost. Subgroup analyses considered age and disease type.

RESULTS

Among 1318 ICU admissions from the ED, 36% were subjected to boarding for over 6 h. Prolonged boarding had a longer ICU (8.9 ± 8.8 vs. 11.2 ± 12.2 days, P < .001) and hospital (17.8 ± 20.1 vs. 22.8 ± 23.0 days, P < .001) stay, higher treatment cost (10.4 ± 13.9 vs. 13.2 ± 16.5 thousands of USD, P = .001), and hospital mortality (19% vs. 25% P = .020). Multivariate regression analysis showed a longer ICU stay in patients aged 65-79 (8.3 ± 8.4 vs. 11.8 ± 14.2 days, P < .001) and cardiology patients (6.9 ± 8.4 vs. 8.8 ± 9.7 days, P = .001). Besides, the treatment cost was also higher for both groups (10.4 ± 14.6 vs. 13.7 ± 17.7 thousands of USD, P = .004 and 8.4 ± 14.0 vs. 11.7 ± 16.6 thousands of USD, P < .001, respectively).

CONCLUSION

Extended ED boarding for critically ill medical patients over 65 years old was associated with negative outcomes, including longer ICU/hospital stays, higher treatment costs, and hospital mortality.

Clinical Frailty Score is a good predictor of postoperative mortality in patients undergoing open abdomen surgery: a multicenter retrospective cohort study

BACKGROUND

Open Abdomen (OA) is gaining popularity in damage control surgery (DCS) but there is not an absolute prognostic score to identify patients that may benefit from it. Our study investigates the correlation between the clinical frailty scale score (CFSS) and postoperative morbidity and mortality in patients undergoing OA.

METHODS

Patients ≥65 yo undergoing OA in two referral centres between 2015 and 2020 were included and stratified according to CFSS in non-frail (NF), frail (F) and highly-frail (HF). The primary endpoint was 30-day mortality. Secondary endpoints were postoperative morbidity and 1- year survival.

RESULTS

One hundred and thirty-six patients were included: 35 NF (25.7%), 56 F (41.2%), 45 HF (33.1%). Average age 76.8. The 73.5% of cases were non-traumatic diseases with no difference in preoperative characteristics. 95 (71.4%) had one complication, 26 NF (74.3%), 34 F (63.2%), 35 HF (77.8%) (P=0.301) and 59.4% had a complication with a CD≥3, 57.1% NF, 56.6% F and 64.4 HF. The 30-day mortality was 32.4%, higher in HF (46.7%) and F (30.4%) compared to NF (17.1%, P=0.018). The Overall 1-year survival was 41% (SE ±4) with statistically significant difference between HF vs. NF and HF vs. F (P=0.009 and P=0.029, respectively). In the univariate analysis, the only significant prognostic factor impacting mortality was CFSS, with HF having an HR of 1.948 (95% CI 1.097-3.460, P=0.023).

CONCLUSIONS

When OA is a surgical option, frail patients should not be precluded, while HF should be carefully evaluated. The CFSS might be a good prognostic score for patients that may safely benefit from OA.

Association between social support and ambulance use among older people in Japan: an empirical cross-sectional study

BACKGROUND

Ambulance service demand and utilization are increasing worldwide. To address this issue, the factors that affect ambulance use must be identified. Few studies have examined factors that can intervene and thus reduce the frequency of ambulance use. This study aimed to examine the association between social support and ambulance use among older adults in Japan. We hypothesize that social support is associated with reduced ambulance use.

METHODS

This cross-sectional study was conducted as part of the Japan Gerontological Evaluation Study. In December 2019 and January 2020, we collaborated with individuals aged 65 years or above with no long-term care needs. A total of 24,581 participants were included in the analysis. The objective and explanatory variables were ambulance use and social support, respectively. Binomial regression analysis was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

Social support was associated with ambulance use. People who had no one to listen to their complaints or worries were significantly more likely to use ambulance services than those who did (OR [95% CI] = 1.26 [1.03-1.53]). People with no one to take care of them when they were ill were also significantly more likely to use ambulance services than those who had someone to provide care (1.15 [1.01-1.31]). Moreover, the results of binomial logistic regression analysis indicated that individuals who called an ambulance but were not hospitalized had significantly lower social support compared to those who did not call an ambulance.

CONCLUSIONS

The results suggest that the presence and quality of social support play a significant role in ambulance use among older adults in Japan. Our findings can help policymakers to plan and implement strategies for reducing the burden on emergency medical care.

Influence of the COVID-19 Outbreak in Vulnerable Patients (Pediatric Patients, Pregnant Women, and Elderly Patients) on an Emergency Medical Service System: A Pre- and Post-COVID-19 Pandemic Comparative Study Using the Population-Based ORION Registry

Background and Objective: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread all over the world. To assess the influence of the COVID-19 pandemic on emergency medical services (EMS) for vulnerable patients transported by ambulance. Materials and Methods: This study was a retrospective, descriptive study with a study period from 1 January 2019 to 31 December 2021 using the Osaka Emergency Information Research Intelligent Operation Network (ORION) system. We included all pediatric patients, pregnant women, and elderly patients ≥ 65 years of age transported by ambulance in Osaka Prefecture. The main outcome of this study was difficult-to-transport cases. We calculated the rate of difficult-to-transport cases under several conditions. Results: For the two year-long periods of 1 January 2019 to 31 December 2019 and 1 January 2021 to 31 December 2021, a total of 887,647 patients were transported to hospital by ambulance in Osaka Prefecture. The total number of vulnerable patients was 579,815 (304,882 in 2019 and 274,933 in 2021). Multivariate logistic regression analysis showed that difficult-to-transport cases were significantly more frequent in 2021 than in 2019. Difficult-to-transport cases were significantly less frequent in the vulnerable population than in the non-vulnerable population (adjusted odds ratio 0.81, 95% confidence interval 0.80-0.83; p < 0.001). Conclusion: During the pandemic (2021), difficult-to-transport cases were more frequent compared to before the pandemic (2019); however, vulnerable patients were not the cause of difficulties in obtaining hospital acceptance for transport.

Telemedicine in Nursing Home Residents Requiring a Call to an Emergency Medical Communication Center

OBJECTIVES

To compare the proportion of nursing home residents dispatched to an emergency department (ED) after a call to the emergency medical communication center (EMCC) according to the availability or nonavailability of telemedicine.

DESIGN

This prospective, observational trial was conducted in the EMCC and 74 nursing homes in a French county.

SETTING AND PARTICIPANTS

All nursing home residents who needed to contact the EMCC between June 2019 and April 2020 were included in the study. We excluded calls notifying the death of a resident, for completing data from a previous call, and for nursing home staff.

METHODS

The primary outcome was the proportion of residents dispatched to an ED after their first call to the EMCC. The secondary outcomes were the proportion of second calls, proportion of residents dispatched to an ED after a second call, and proportion of death within 30 days.

RESULTS

We included 3103 calls in the final analysis (355 from equipped nursing homes and 2748 from unequipped nursing homes). The proportion of patients dispatched to an ED after the first call was lower among telemedicine-equipped than among telemedicine-unequipped nursing homes (41% vs 50%; odds ratio, 0.71; 95% CI, 0.56-0.90). The proportion of a second call for the same purpose within 72 hours, proportion of dispatching to an ED at the second call, and proportion of deaths within 30 days were similar between the groups.

CONCLUSION AND IMPLICATIONS

The use of telemedicine by nursing home residents requiring a call to the EMCC is associated with a reduction in the number of dispatches to an ED without any increase in the number of 72-hour callbacks or 30-day mortality rates.

Introducing a pharmacist-led transmural care program to reduce drug-related problems in orthogeriatric patients: a prospective interventional study

BACKGROUND

Orthogeriatric patients have an increased risk for complications due to underlying comorbidities, chronic drug therapy and frequent treatment changes during hospitalization. The clinical pharmacist (CP) plays a key role in transmural communication concerning polypharmacy to improve continuity of care by the general practitioner (GP) after discharge. In this study, a pharmacist-led transmural care program, tailored to orthogeriatric patients, was evaluated to reduce drug related problems (DRPs) after discharge.

METHODS

An interventional study was performed (pre-period: 1/10/2021-31/12/2021; post-period: 1/01/2022-31/03/2022). Patients (≥ 65 years) from the orthopedic department were included. The pre-group received usual care, the post-group received the pharmacist-led transmural care program. The DRP reduction rate one month after discharge was calculated. Associated factors for the DRP reduction rate were determined in a multiple linear regression analysis. The GP acceptance rate was determined for the proposed interventions, as well as their clinical impact using the Clinical, Economic and Organizational (CLEO) tool. Readmissions one month after discharge were evaluated.

RESULTS

Overall, 127 patients were included (control n = 61, intervention n = 66). The DRP reduction rate was statistically significantly higher in the intervention group compared to the control group (p < 0.001). The pharmacist's intervention was associated with an increased DRP reduction rate (+ 1.750, 95% confidence interval 1.222-2.278). In total, 141 interventions were suggested by the CP, of which 71% were accepted one month after discharge. In both periods, four patients were readmitted one month after discharge. 58% of the interventions had a clinical impact (≥ 2 C level using the CLEO-tool) according to the geriatrician and for the CP it was 45%, indicating that they had the potential to avoid patient harm.

CONCLUSIONS

The pharmacist-led transmural care program significantly reduced DRPs in geriatric patients from the orthopedic department one month after discharge. The transmural communication with GPs resulted in a high acceptance rate of the proposed interventions.

Impact of First Wave of COVID-19 Pandemic on Mortality at Emergency Department in Older Patients with COVID and Non-COVID Diagnoses

INTRODUCTION

Mortality in emergency departments (EDs) is not well known. This study aimed to assess the impact of the first-wave pandemic on deaths accounted in the ED of older patients with COVID and non-COVID diseases.

METHODS

We used data from the Emergency Department and Elderly Needs (EDEN) cohort (pre-COVID period) and from the EDEN-COVID cohort (COVID period) that included all patients ≥65 years seen in 52 Spanish EDs from April 1 to 7, 2019, and March 30 to April 5, 2020, respectively. We recorded patient characteristics and final destination at ED. We compared older patients in the pre-COVID period, with older patients with non-COVID and with COVID-19. ED-mortality (before discharge or hospitalization) is the prior outcome and is expressed as an adjusted odds ratio (aOR) with 95% interval confidence.

RESULTS

We included 23,338 older patients from the pre-COVID period (aged 78.3 [8.1] years), 6,715 patients with non-COVID conditions (aged 78.9 [8.2] years) and 3,055 with COVID (aged 78.3 [8.3] years) from the COVID period. Compared to the older patients, pre-COVID period, patients with non-COVID and with COVID-19 were more often male, referred by a doctor and by ambulance, with more comorbidity and disability, dementia, nursing home, and more risk according to qSOFA, respectively (p < 0.001). Compared to the pre-COVID period, patients with non-COVID and with COVID-19 were more often to be hospitalized from ED (24.8% vs. 44.3% vs. 79.1%) and were more often to die in ED (0.6% vs. 1.2% vs. 2.2%), respectively (p < 0.001). Compared to the pre-COVID period, aOR for age, sex, comorbidity and disability, ED mortality in elderly patients cared in ED during the COVID period was 2.31 (95% confidence interval [CI]: 1.76-3.06), and 3.75 (95% CI: 2.77-5.07) for patients with COVID. By adding the variable qSOFA to the model, such OR were 1.59 (95% CI: 1.11-2.30) and 2.16 (95% CI: 1.47-3.17), respectively.

CONCLUSIONS

During the early first pandemic wave of COVID-19, more complex and life-threatening older with COVID and non-COVID diseases were seen compared to the pre-COVID period. In addition, the need for hospitalization and the ED mortality doubled in non-COVID and tripled in COVID diagnosis. This increase in ED mortality is not only explained by the complexity or severity of the elderly patients but also because of the system's overload.

[Geriatric ultrasound : Prospective evaluation of ultrasound as extended screening in acute geriatric patients]

BACKGROUND

The aim of this study was to evaluate ultrasound as a routinely used procedure and extended physical examination in geriatric patients in acute care.

METHODS

Prospective study of 86 patients using ultrasound as a screening examination (abdomen, basal sections of the thorax, thyroid glands) under comparative use of a hand-held ultrasound device (HHUSD) and a high-end ultrasound (HEUS = gold standard).

RESULTS

In 20/86 (23.2%) clinically relevant findings with therapeutic consequences were found (pleural effusion, urinary retention, choledocholithiasis metatases, colon tumor). In 22/86 (25.6%) patients, additional questions existed besides the screening indication: tumor search (9.3%), anemia (5.8%), liver value elevation (5.8%), dyspnea (5.8%), splenic pathologies (2.3%), weight loss (1.2%), infectious focus (1.2%), diarrhea (1.2%), intra-abdominal hematoma (1.1%), abdominal aortic aneurysm (1.2%). The most common sonographic findings included: cholecystolithiasis (32.6%); right pleural effusion (31.4%), thyroid nodules (30.2%), renal cysts (27.9%), and fatty liver (26.7%). There were significant differences in sizing between HHUSD and HEUS (kidneys, pancreatic corpus and pancreatic caudal diameters, portal vein, left hepatic vein) without diagnostic relevance.

CONCLUSION

The extended screening by ultrasound provided important answers to classical questions in geriatrics (e.g. urinary retention, volume deficiency/pleural effusion) in many cases. The new findings had therapeutic consequences in one fifth of the patients. The HHUSD can be used in screening.

Epidemiology and clinical characteristics of trauma in older patients transferred from long-term care hospitals to emergency departments: A nationwide retrospective study in South Korea

BACKGROUND

South Korea's aging population had leg to an increased number of long-term care hospitals (LTCHs), and increased transfer of older patients to emergency departments (EDs). This study investigated the epidemiological and injury profiles of LTCH patients aged ≥65 who were transferred from LTCHs to EDs due to trauma.

METHOD

This retrospective study conducted between January 2014 and December 2019 in South Korea utilized data from the National Emergency Department Information System. The requirement for informed consent was waived by the IRB due to the retrospective nature of the study. Patient information was anonymized prior to analysis.

RESULTS

Of the 1,472,006 trauma cases aged ≥65, 14,469 came from LTCHs. Outcomes varied: 44.1% were discharged, 40.6% were admitted to general wards (GW), 5.9% to intensive care units (ICU), 2.4% to other hospitals, and 6.5% returned to LTCHs. ED length of stay (LOS) was longest in the death (410.28 ± 559.73 min) and GW admission (390.12 ± 621.71 min) groups. Falls were the main cause of injury (50.1%), and the most common fracture was femoral (71.6%). Femoral and shoulder/upper extremity fractures increased hospitalization risk only, whereas self-harm increased both hospitalization and mortality risk.

CONCLUSION

Visits to the ED by older patients from LTCH for trauma were avoidable in 50.6% of cases. Additionally, these patients had longer ED LOS and higher hospitalization rates than non-LTCH patients. Falls were the predominant mode of presentation, femoral fracture was the most common fracture among patients from LTCH.

A consensus statement on minimum operational standards for geriatric emergency care in Belgium: a modified Delphi study

BACKGROUND

As emergency department (ED) leaders started integrating geriatric emergency guidelines on a facultative basis, important variations have emerged between EDs in care for older patients. The aim of this study was to establish a consensus on minimum operational standards for Geriatric ED care in Belgium.

METHODS

A two-stage modified Delphi study was conducted. Twenty panellists were recruited from Dutch and French speaking regions in Belgium to join an interdisciplinary expert panel. In the first stage, an online survey was conducted to identify and define all possible elements of geriatric emergency care. In the second stage, an online survey and online expert panel meeting were organized consecutively to determine which elements should be recognized as minimum operational standards.

RESULTS

Between March 2020 and February 2021, the expert panel developed a broad consensus including ten statements focusing on the target population, specific goals, availability of geriatric practitioners and quality assurance. Additionally, the expert panel also determined which protocols, materials and accommodation criteria should be available in conventional EDs (39 standards) and in observational EDs (57 standards).

CONCLUSIONS

This study presents a consensus on minimum operational standards for geriatric emergency care in two ED types: the conventional ED and the observational ED. These findings may serve as a starting point towards broadly supported minimum standards of care stipulated by legislation in Belgium or other countries.

[Utility and safety of direct admission to acute geriatric unit after Nursing Home Geriatric Team assessment]

BACKGROUND AND OBJECTIVE

More than half of institutionalized older people need a emergency department visit annually, with high resources consumption and higher risk of adverse events, due to high complexity. Direct admission to Acute Geriatric Unit (AGU), after geriatric consultant and nursing home medical team assessment, could be a safety and effective alternative to emergency department (ED) admission.

METHODS

Retrospective observational study of AGU patients admitted by Nursing Home Geriatric Team between January, 1st and December, 31st, 2021. Planned admissions and SARS-CoV-2 positive patients were excluded. Medical (sociodemographic, clinical, functional and cognitive) records and outcomes data (inpatient mortality, hospital and ED lenght of stay, transfer to ED and delirium within 48h after admission, hospital discharge location) were collected.

RESULTS

Two hundred and six patients directly admitted, 101 through ED (N 307). 62.5% with Barthel index <40, 65% with dementia, 56.4% with Charlson index ≥3. Inpatient mortality was 14.6% in direct admission, 20.8% in ED referral group, p=0.14. Hospital lenght of stay was 9.61±6.01 days in direct admission, 11.22±5.36 days in ED group, p=0.02. 27.7% of patients with delirium in direct admission and 36.6% in ED group; only one patient was transferred to ED, within 48h after admission.

CONCLUSIONS

Direct admission is a safety and effective alternative to ED referral in institutionalized older people after geriatric assessment, due to no increased mortality, shorter length of stay and hospital cost reduction.

Screening Tool Risk Score Assessment in the Emergency Department for Geriatric (S-TRIAGE) in 28-day mortality

BACKGROUND

The number of older adults with a high risk of frailty and severe illness continues to increase. Moreover, physiological change and multiple comorbidities are challenging to triage in geriatrics. Therefore, we aimed to evaluate variables to predict 28-day mortality and develop a screening tool to predict mortality and lifesaving intervention among geriatric patients in the emergency department (ED).

METHODS

This study was a retrospective, single-center, observational study at the ED of Ramathibodi Hospital, Bangkok. Patients aged ≥ 65 years who visited the ED between January 2018 and December 2019 were enrolled. In the development cohort, univariable logistic regression was used to identify predictors of 28-day mortality in older patients. A predictive model for mortality and the need for lifesaving intervention was developed by multivariable logistic regression. In addition, the score was validated with internal validation and compared between development and validation set by chi-square.

RESULTS

We enrolled 1393 patients. In the development cohort, among these 1002 patients, 103 (10.3%) of whom died within 28 days. Malignancy, shock index (SI), systolic blood pressure (SBP) < 100 mmHg, and altered mentation were independent risk factors of 28-day mortality. We developed new screening tools named the S-TRIAGE score, which has the respiratory rate (< 11, > 22 breaths/min), the ratio of pulse oximetric saturation to the fraction of inspired oxygen (< 420, 420-450), SI (> 1, 0.6-0.99), SBP < 100 mmHg, body temperature (< 36, > 37.5 °C), and mental change. The area under a receiver operating characteristic (ROC) curve of the S-TRIAGE score in the validation cohort was 0.826 [95% confidence interval (95%CI) 0.773-0.879] in predicting mortality and lifesaving intervention, and the clinical score classified patients into five groups.

CONCLUSION

This study showed malignancy, hypotension, increased SI, and mental status change were predictive factors for 28-day mortality in older adults in the ED. The screening tool risk score for geriatrics used in this study is potentially a good predictor of mortality and lifesaving intervention in high-risk older patients in the ED.

Prescription errors by emergency physicians for inpatients are associated with emergency department length of stay

OBJECTIVES

Adverse drug events are the sixth-leading cause of death in Western countries and are also more frequent in emergency departments (EDs). In some hospitals or on some occasions, ED physicians prescribe for patients who they have admitted. These prescriptions are then followed by the wards and can persist for several days. Our objectives were to determine the frequency of prescription errors for patients over 18years old hospitalized from ED to medical or surgical wards, and whether there exists a relationship between those prescription errors and ED LOS.

METHODS

This was a single center retrospective study that was conduct in the ED of a university hospital with an annual census of 65 000 patients. The population studied consisted of patients over 18years old hospitalized from ED to medical or surgical wards between January 1st, 2012 and January 21st, 2012.

RESULTS

Six hundred eight patients were included. One hundred fifty-four (25%) patients had prescription errors. Prescription errors were associated with increased ED length of stay (OR=2.47; 95% CIs [1.58; 3.92]) and polypharmacy (OR=1.78; 95% CIs [1.20; 2.66]). Fewer prescription errors were found when the patient was examined in the ED by a consultant (OR=0.61; 95% CIs [0.41; 0.91]) and when the medical history was known (OR=0.28; 95% CIs [0.10; 0.88]).

CONCLUSION

Prescription errors occurred frequently in the ED. We assume that a clear communication and cooperation between EPs and consultants may help improve prescription accuracy.

Older patients with nonspecific complaints at the Emergency Department are at risk of adverse health outcomes

OBJECTIVE

Older adults at the Emergency Department (ED) often present with nonspecific complaints (NSC) such as 'weakness' or 'feeling unwell'. Health care workers may underestimate illness in patients with NSC, leading to adverse health outcomes. This study compares characteristics and outcomes of NSC-patients versus specific complaints (SC) patients.

METHODS

Cohort study in patients ≥ 70 years in two Dutch EDs. NSC was classified according to the BANC-study-framework based on the medical history in the ED letter, before additional diagnostics took place. A second classification was performed at the end of the ED visit/hospital admission. Primary outcomes were functional decline, institutionalization, and mortality at 30 days.

RESULTS

26% (n = 228) of a total of 888 included patients presented with NSC. Compared with SC-patients, NSC-patients were older, more frail, and more frequently female. NSC-patients had a higher risk of functional decline and institutionalization at 30 days (adjusted ORs 1.84, 95% CI 1.27 - 2.72, and 2.46, 95% CI 1.51-4.00, respectively), but not mortality (adjusted OR 1.26, 95% CI 0.58 - 2.73). Reclassification to a specific complaint after the ED visit or hospital admission occurred in 54% of NSC-patients.

CONCLUSION

NSC occur especially in older, frail female patients and are associated with an increased risk of functional decline and institutionalization, even after adjustment for worse baseline status. In half of the patients, a specific complaint revealed during ED or hospital stay. Physicians at the ED should consider NSC as a red flag needing appropriate observation and evaluation of underlying serious conditions and needs of this vulnerable patient group.

Mortality before and after reconfiguration of the Danish hospital-based emergency healthcare system: a nationwide interrupted time series analysis

OBJECTIVES

The study aimed to investigate how the 'natural experiment' of reconfiguring the emergency healthcare system in Denmark affected in-hospital and 30-day mortality on a national level. The reconfiguration included the centralisation of hospitals and the establishment of emergency departments with specialists present around the clock.

DESIGN

Hospital-based cohort study.

SETTING

All public hospitals in Denmark.

PARTICIPANTS

Patients with an unplanned contact from 1 January 2007 until 31 December 2016.

INTERVENTIONS

Stepped-wedge reconfiguration of the Danish emergency healthcare system.

MAIN OUTCOME MEASURES

We determined the adjusted ORs for in-hospital mortality and HRs for 30-day mortality using logistic and Cox regression analysis adjusted for sex, age, Charlson Comorbidity Index, income, education, mandatory referral and the changes in the out of hours system in the Capital Region. The main outcomes were stratified by the time of arrival. We performed subgroup analyses on selected diagnoses: myocardial infarction, stroke, pneumonia, aortic aneurysm, bowel perforation, hip fracture and major trauma.

RESULTS

We included 11 367 655 unplanned hospital contacts. The adjusted OR for overall in-hospital mortality after reconfiguration of the emergency healthcare system was 0.998 (95% CI 0.968 to 1.010; p=0.285), and the adjusted OR for 30-day mortality was 1.004 (95% CI 1.000 to 1.008; p=0.045)). Subgroup analyses showed some possible benefits of the reconfiguration such as a reduction in-hospital and 30-day mortality for myocardial infarction, stroke, aortic aneurysm and major trauma.

CONCLUSIONS

The Danish emergency care reconfiguration programme was not associated with an improvement in overall in-hospital mortality trends and was associated with a slight slowing of prior improvements in 30-day mortality trends.

Improvement of the Identification of Seniors at Risk scale for predicting adverse health outcomes of elderly patients in the emergency department

OBJECTIVES

To explore the validity of the Chinese version of the Identification of Seniors at Risk (ISAR) screening tool in emergency rooms (ERs) to identify elderly patients prone to adverse outcomes after being discharged from the ER.

METHODS

A prospective single-center observational study design was adopted and included 497 elderly (aged ≥65 years) ER patients of a medical center in northern Taiwan. Before discharge from the ER, baseline sociodemographic and clinic data were collected by researchers and the ISAR was administered. Adverse health outcomes (ER revisits, readmissions, and mortality) at 30 days were evaluated by medical records and follow-up telephone interviews.

RESULTS

ISAR screening showed that 334 (67.2%) elderly patients in the ER were at high risk after discharge. Higher-risk patients were older, had had a fall within the previous 6 months, and had complex comorbidities. The ISAR had good sensitivity (0.77∼1.00) for screening adverse health outcomes in these elderly patients. The discrimination of the ISAR for adverse health outcomes was 0.60∼0.77, and it increased to 0.64∼0.80 when the age-adjusted Charlson comorbidity index (ACCI) was simultaneously considered.

CONCLUSIONS

The ISAR exhibited good sensitivity for screening adverse outcomes for elderly patients at risk. The ACCI is recommended to simultaneously be considered to improve the prognostic performance of the ISAR.

Validity of the Korean triage and acuity scale in older patients compared to the adult group

INTRODUCTION

While many patients visit the emergency department (ED) for various reasons, medical resources are limited. Therefore, various triage scale systems have been used to predict patient urgency and severity. South Korea has developed and used the Korean Triage and Accuracy Scale (KTAS) based on the Canadian classification tool. As the elderly population increases, the number of elderly patients visiting the ED also increases. However, in KTAS, there is no consideration for the elderly, and the same classification system as adults. The aim of this study is to verify the ability of KTAS to predict severity levels in the elderly group, compared to the adult group.

METHODS

This is a retrospective study for patients who visited the ED at two centers between February 1, 2018 and January 31, 2021. The initial KTAS level, changed level at ED discharge, general patient character, ED treatment results, in-hospital mortality, and lengths of hospital and ED stays were acquired. Area under the receiver operating characteristics (AUROC) was used to verify the severity prediction ability of the elderly group to KTAS, and logistic regression analysis was used for the prediction up-triage of KTAS.

RESULTS

The enrolled patients in the study were 87,220 in the adult group and 37,627 in the elderly group. The proportion of KTAS up-triage was higher in the elderly group (1.9 % vs. 1.2 %, p < 0.001). The AUROC for the overall admission rate was 0.686, 0.667 in the adult and elderly group, the AUROC for ICU admission was 0.842, 0.767, and the AUROC for in-hospital mortality prediction was 0.809, 0.711, indicating a decrease in the AUROC value in the elderly group. The independent factors of the up-triage predictors were old age, male gender, pulse, and ED length of stay, and old age was the most influential variable.

CONCLUSION

KTAS was poorly associated with severity in the elderly than in adults, and it was found that up-triaging was more likely to occur in the elderly. The severity and urgency of patients over 65 years of age should not be underestimated when initially determining the triage scale.

[Four types of old patients in the emergency department : A geriatric medicine qualitative and economic viewpoint]

BACKGROUND

Lack of clinical management of old patients in the emergency department.

QUESTION

How can we manage old patients in the emergency department more effectively, medically and economically?

METHODS

Evaluation of current selection and screening methods and recommendations for old patients in the emergency department. Acute inpatient treatment needs, presence of dysfunction in at least two core areas and assessment of advance care needs are examined.

RESULT

The identification of old patients in the emergency department as geriatric patients alone shows no control potential. Combining the three test criteria of acute inpatient need for treatment, the presence of dysfunction in at least two core areas and the assessment of advance care needs generates four old patient types that have interesting control potential: the medical traumatology patient, the acute geriatric patient, the rehabilitative geriatric patient, and the ambulatory patient.

DISCUSSION

in addition to identifying geriatric patients, screening should map acute inpatient treatment needs, assessment of dysfunction, and analysis of advance care needs to define clinically steerable old patients.

Potentially avoidable hospitalizations for older patients transferred from long-term care hospitals: a nationwide cross-sectional analysis of potential healthcare consequences

Multiple chronic disorders and disabilities among older patients in long term care hospitals (LTCH) tends to increase the healthcare burden by causing overcrowding, particularly in emergency departments. Therefore, access to timely and adequate healthcare for LTCH patients is an increasingly important issue, and potentially avoidable hospitalizations (PAHs) and hospitalizations during non-office hours can result as indicators of emergency department overcrowding. The study aimed to evaluate PAHs and hospitalizations during non-office hours in emergency departments for older patients transferred from LTCH compared to patients living at home. We performed a cross-sectional study using the National Emergency Department Information System database from January 2018 to December 2019, in South Korea, with older patients (≥ 65 years) who visited nationwide emergency departments. Adjusted odds ratio (aOR) and 95% confidence interval (CI) for indicators of overcrowding as PAHs and hospitalizations during non-office hours were calculated by logistic regression. Among the 2,177,663 older patients who visited the emergency departments, 98,434 patients were living in LTCH and 2,079,229 patients were living at home. The older patients living in LTCH was associated with PAHs (aOR: 1.90, 95% CI 1.87-1.94) and hospitalizations during non-office hours (aOR: 1.76, 95% CI 1.73-1.78). LTCH patients showed more hospital visits, extended stay in the emergency department, greater prevalence of chronic diseases, greater rates of transfer as well as higher admission rates and mortality as compared to the patients living at home. The LTCH older patients were associated with the indicators of emergency department overcrowding, which impacts health care quality in hospitals. Introduction of policy and training programs for LTCH staff are recommended to manage vulnerable groups in advance.

Exploring biomarkers in routine diagnostics for the risk stratification of older patients in the Chest Pain Unit: a prospective cohort study

OBJECTIVES

This study aims to estimate the association of the often, in daily clinical practice, used biological age-related biomarkers high-sensitivity troponin-T (hs-TnT), C reactive protein (CRP) and haemoglobin (Hb) with all-cause mortality for the purpose of older patient's risk stratification in the emergency department (ED).

DESIGN

Exploratory, prospective cohort study with a follow-up at 2.5 years after recruitment started. For the predictors, data from the hospital files including the routinely applied biological age-related biomarkers hs-TnT, CRP and Hb were supplemented by a questionnaire.

SETTING

A cardiological ED, Chest Pain Unit, University Hospital Heidelberg, Germany.

PARTICIPANTS

N=256 cardiological ED patients with a minimum age of 70 years and the capability to informed consent.

PRIMARY OUTCOME MEASURES

The primary outcome of this study was all-cause mortality which was assessed by requesting registry office information.

RESULTS

Among N=256 patients 63 died over the follow-up period. Positive results in each of the three biomarkers alone as well as the combination were associated with increased all-cause mortality at follow-up. The number of positive age-related biomarkers appeared to be strongly indicative of the risk of mortality, even when controlled for major confounders (age, sex, body mass index, creatinine clearance and comorbidity).

CONCLUSIONS

In older ED patients, biomarkers explicitly related to biological ageing processes such as hs-TnT, CRP and Hb were to a certain degree independently of each other as well as combined associated with an increased risk of all-cause mortality. Thus, they may have the potential to be used to supplement the general risk stratification of older patients in the ED. Validation of the results in a large dataset is needed.

Frailty Screening in the Emergency Department: Comparing the Variable Indicative of Placement Risk, Clinical Frailty Scale and PRISMA-7

Prompt recognition of frailty in the emergency department (ED) is important to identify patients at higher risk of adverse outcomes. Despite this, few studies examine the diagnostic accuracy of screening instruments for frailty, instead focusing on predictive validity. We compared three commonly used, short frailty screens to an independent comprehensive geriatric assessment (CGA) in an urban University Hospital ED. Consecutive attendees aged ≥70 years were screened by trained raters, blind to the CGA, with the Variable Indicative of Placement risk (VIP), 3 and 4-item versions, Clinical Frailty Scale (CFS) and PRISMA-7. Accuracy was measured from the area under the ROC curve (AUROC). In total, 197 patients were included, median age 79 (±10); 46% were female. Half (49%) were confirmed as frail after CGA. All instruments differentiated frail from non-frail states, although the CFS (AUROC: 0.91) and PRISMA-7 (AUROC: 0.90) had higher accuracy compared to the VIP-4 (AUROC: 0.84) and VIP-3 (AUROC: 0.84). The CFS was significantly more accurate than the VIP-3 (p = 0.026) or VIP-4 (p = 0.047). There was no significant difference between the CFS and PRISMA-7 (p = 0.90). The CFS and PRISMA-7 were more accurate and should be considered in preference to the VIP (3 or 4-item versions) to identify frailty in EDs.

Association of age with emergency department visits and hospital admissions: A nationwide study

AIM

Older adults are frequently stigmatized for improper emergency department (ED) visits and hospitalizations. In this study, we aimed to investigate the relationship between age and appropriateness of ED visits, and the mismatching between ED clinical severity and hospitalizations.

METHODS

We carried out a nationwide assessment of Italian Informative System for the Emergency and Urgency data from 1 January 2015 to 31 December 2015 including patients admitted to all the Italian EDs for any reason. Appropriateness of ED visits was defined as a yellow/red/black color code (potentially life-threatening/dead patients), whereas clinical severity/hospitalization mismatching was defined as hospital admission after validated ED green/white codes. Analyses dedicated to people aged ≥75 years were carried out.

RESULTS

There were 20 400 071 ED visits (3 444 091 aged ≥75 years), which increased with age, up to >650/1000 inhabitants aged ≥90 years. The appropriateness of ED visits increased with age, from 6.3% in the 5-9 years age group to 44.2% in the 95-99 years age group. Clinical severity/hospitalization mismatching decreased with age, from 62.9% in the 30-34 years age group to 27.7% in the 95-99 years age group. At ED presentation, 21.6% of patients aged ≥75 years complained of non-specific symptoms, and hospital discharge diagnoses frequently differed from the ED admission diagnoses; 11.4% died during hospitalization and 8.8% were discharged to long-term care facilities.

CONCLUSIONS

The request for ED care and the admission to acute care ward are commonly appropriate for older patients. Clinical presentation at ED admission is frequently atypical. Health care systems should aim at improving outpatients' management to reduce the ED care need, but also at optimizing in-hospital strategies and pathways for older adults.

Comprehensive geriatric assessment in the emergency department: A protocol for a prospective cohort study

Background: Comprehensive geriatric assessment (CGA) has been shown to improve outcomes in hospitalised older adults; however, there is currently no compelling evidence to support CGA interventions within the Emergency Department (ED). The aim of this study is  to explore the clinical and process outcomes of older adults who receive ED-CGA over a period of six months after their initial ED attendance.

Design: Prospective cohort study.

Methods: The STrengthening the Reporting of the OBservational studies in Epidemiology (STROBE) standardised reporting guidelines will be adhered to. Older adults aged ≥65 years who score ≥2 on the Identification of Seniors at Risk (ISAR) tool and present to the ED with a medical complaint during the operational hours of the dedicated interdisciplinary team, will be considered eligible for recruitment. Demographic and health assessment information will be obtained at the ED index attendance followed by completion of an interdisciplinary CGA. A dedicated research nurse will complete follow-up telephone interviews with participants at 30 days and six months. The primary outcome will be incidence of hospital admission from the ED index attendance. Secondary outcomes will include functional decline, patient satisfaction with the ED index attendance, unscheduled ED reattendance(s), unscheduled hospital (re)admission(s), nursing home admission(s), healthcare utilisation, and death. Descriptive statistics will be used to profile the characteristics of the study participants and multivariate logistic and linear regression analysis will be used to analyse risk of adverse outcomes.

Ethics and dissemination: Ethical approval was granted by the University of Limerick Hospital Group Research Ethics Committee (107/2021). The authors will disseminate study findings through publication in a peer-reviewed journal and presentation at national and international conferences. Patient and public involvement will be sought from a panel of older adults at the Ageing Research Centre in the University of Limerick.

Motoric cognitive risk syndrome and incident hospitalization in Quebec's older population: Results of the NuAge cohort study

Background

Screening older adults at risk of hospitalization is essential to prevention of this adverse event. Motoric cognitive risk syndrome (MCR) has been associated with incident dementia and falls, which are both risk factors of hospitalization. There is no information on the association of MCR with incident hospitalization in older adults.

Objective

The study aims to examine the association of MCR with incident hospitalization in community-dwelling older adults.

Design

Quebec older population-based observational cohort study with 3 years of follow-up.

Setting

Community dwellings.

Subjects

A subset of 999 participants recruited in the NuAge study.

Methods

Participants with MCR (i.e., with slow gait and cognitive complaint without dementia or motor disability) were identified at baseline assessment. Incident hospitalization (i.e., ≥1) and its recurrence (i.e., ≥2) were collected annually over a 3 year follow-up period.

Results

The prevalence of MCR was 5.0% at baseline. The overall incidence of hospitalization was 29.0% and its recurrence 4.8%. MCR was associated with incident recurrent hospitalization [adjusted Hazard Ratio (aHR) = 2.58 with 95% Confidence Interval (CI) = (1.09–6.09) and P = 0.031], but not with incident hospitalization [aHR = 1.48, with 95%CI = (0.95–2.28) and P = 0.081].

Conclusion

MCR is associated with incident recurrent hospitalization in NuAge participants, suggesting that MCR may be of clinical interest for screening individuals at risk for hospitalization in Quebec's older population.

The effectiveness of interventions to reduce adverse outcomes among older adults following Emergency Department discharge: umbrella review

Background

Population ageing is increasing rapidly worldwide. Older adults are frequent users of health care services including the Emergency Department (ED) and experience a number of adverse outcomes following an ED visit. Adverse outcomes include functional decline, unplanned hospital admission and an ED revisit. Given these adverse outcomes a number of interventions have been examined to improve the outcomes of older adults following presentation to the ED. The aim of this umbrella review was to evaluate the effectiveness of ED interventions in reducing adverse outcomes in older adults discharged from the ED.

Methods

Systematic reviews of randomised controlled trials investigating ED interventions for older adults presenting to the ED exploring clinical, patient experience and healthcare utilisation outcomes were included. A comprehensive search strategy was employed in eleven databases and the PROSPERO register up until June 2020. Grey literature was also searched. Quality was assessed using the A MeaSurement Tool to Assess Systematic Reviews 2 tool. Overlap between systematic reviews was assessed using a matrix of evidence table. An algorithm to assign the Grading of Recommendations Assessment, Development and Evaluation to assess the strength of evidence was applied for all outcomes.

Results

Nine systematic reviews including 29 randomised controlled trials were included. Interventions comprised of solely ED-based or transitional interventions. The specific interventions delivered were highly variable. There was high overlap and low methodological quality of the trials informing the systematic reviews. There is low quality evidence to support ED interventions in reducing functional decline, improving patient experience and improving quality of life. The quality of evidence of the effectiveness of ED interventions to reduce mortality and ED revisits varied from very low to moderate. Results were presented narratively and summary of evidence tables created.

Conclusion

Older adults are the most important emerging group in healthcare for several economic, social and political reasons. The existing evidence for the effectiveness of ED interventions for older adults is limited. This umbrella review highlights the challenge of synthesising evidence due to significant heterogeneity in methods, intervention content and reporting of outcomes. Higher quality intervention studies in line with current geriatric medicine research guidelines are recommended, rather than the publication of further systematic reviews.

The utility of the Barthel index as an outcome predictor in older patients with acute infection attending the emergency department

BACKGROUND

Functional decline and frailty are common in older adults and influence the risk of adverse outcomes. We aimed to assess the value of a Barthel index at the Emergency Department (ED-BI) score in predicting 30-day mortality and ED reconsultation among older patients with acute infection.

METHODS

We performed a prospective multicentre cohort study of older patients (≥75 years) diagnosed with acute infection in 69 Spanish EDs. Demographic, comorbidities, functional status, clinical and analytical data were collected. Unadjusted and adjusted logistic regression models were used to assess the association between ED-BI score, mortality and ED reconsultation.

RESULTS

In total 1596 patients with a mean age of 84.7 years were included in the study and 51.7% female. The most frequent focus of infection was respiratory in 918 patients (57.5%). Patients with an ED-BI< 60 points were significantly older, predominantly female, more likely institutionalized and more urinary infections. When comparing patients with an ED-BI score ≥ 60 points with those< 60 points no differences were found in ED reconsultation but in the latter group mortality at 30-days was higher (p < 0.001).

CONCLUSION

An ED-BI score< 60 points appears to be a strong predictor of mortality at the 30-day follow up in older patients with acute infection.

Profile of Geriatric Patients Attending the Emergency Department of a Tertiary Care Hospital in Karachi: A Cross-Sectional Study

Background and Objectives

The emergency department (ED) is the most important unit of a hospital and is often visited by an ever-increasing proportion of geriatric patients. However, in Pakistan, there is an inadequacy of geriatrics specialists. The objective of this study was to assess the profile of geriatric patients in the ED. We considered main diagnoses, frailty, and other factors that help to come up with certain findings that may assist with policymaking and initiatives for better geriatric care in Pakistan.

Methods

A cross-sectional study was conducted at a hospital in Karachi, Pakistan. The study population comprised 101 patients aged 65 years and older who attended the hospital’s ED from July to September 2021. Data were collected by taking the patients’ histories.

Results

The majority of patients were aged between 65 and 70 years. The most common diagnoses were: gastrointestinal disorders, cerebrovascular accidents, and neurologic disorders. More than half of the patients were found to be frail by the five-item FRAIL questionnaire. The mean Charlson Comorbidity Index score was 5.37 ± 1.88.

Conclusion

It was concluded that the need for geriatric care is worth mentioning since it imposes a significant burden on the ED. The geriatric patients had a higher risk of being on the critical list as most of them were frail and suffered from multiple severe comorbidities. Our results can assist in the development of geriatric emergency medicine and acute care systems in Pakistan.

"Emergency Room Evaluation and Recommendations" (ER2) Tool for the Screening of Older Emergency Department Visitors With Major Neurocognitive Disorders: Results From the ER2 Database

Purpose: The Emergency Room Evaluation and Recommendation (ER²) is an application in the electronic medical file of patients visiting the Emergency Department (ED) of the Jewish General Hospital (JGH; Montreal, Quebec, Canada). It screens for older ED visitors at high risk of undesirable events. The aim of this study is to examine the performance criteria (i.e., sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV], positive likelihood ratio [LR+], negative likelihood ratio [LR-] and area under the receiver operating characteristic curve [AUROC]) of the ER² high-risk level and its "temporal disorientation" item alone to screen for major neurocognitive disorders in older ED visitors at the JGH. Methods: Based on a cross-sectional design, 999 older adults (age 84.9 ± 5.6, 65.1% female) visiting the ED of the JGH were selected from the ER² database. ER² was completed upon the patients' arrival at the ED. The outcomes were ER²'s high-risk level, the answer to ER²'s temporal disorientation item (present vs. absent), and the diagnosis of major neurocognitive disorders (yes vs. no) which was confirmed when it was present in a letter or other files signed by a physician. Results: The sensitivities of both ER²'s high-risk level and temporal disorientation item were high (≥0.91). Specificity, the PPV, LR+, and AROC were higher for the temporal disorientation item compared to ER²'s high-risk level, whereas a highest sensitivity, LR-, and NPV were obtained with the ER² high-risk level. Both area under the receiver operating characteristic curves were high (0.71 for ER²'s high-risk level and 0.82 for ER² temporal disorientation item). The odds ratios (OR) of ER²'s high-risk level and of temporal disorientation item for the diagnosis of major neurocognitive disorders were positive and significant with all OR above 18, the highest OR being reported for the temporal disorientation item in the unadjusted model [OR = 26.4 with 95% confidence interval (CI) = 17.7-39.3]. Conclusion: Our results suggest that ER² and especially its temporal disorientation item may be used to screen for major neurocognitive disorders in older ED users.

Emergency department use and length of stay by younger and older adults: Nottingham cohort study in the emergency department (NOCED)

BACKGROUND

Younger and older adults attending the Emergency Department (ED) are a heterogeneous population. Longer length of ED stay is associated with adverse outcomes and may vary by age.

AIMS

To evaluate the associations between age and (1) clinical characteristics and (2) length of ED stay among adults attending ED.

METHODS

The NOttingham Cohort study in the Emergency Department (NOCED)-a retrospective cohort study-comprises new consecutive ED attendances by adults ≥ 18 years, at a secondary/tertiary care hospital, in 2019. Length of ED stay was dichotomised as < 4 and ≥ 4 h. The associations between age and length of ED stay were analysed by binary logistic regression and adjusted for socio-demographic and clinical factors including triage acuity.

RESULTS

146,636 attendances were analysed; 75,636 (51.6%) resulted in a length of ED stay ≥ 4 h. Attendances of adults aged 65 to 74 years, 75 to 84 years and ≥ 85 years, respectively, had an increased risk (odds ratio (95% confidence interval) of length of ED stay ≥ 4 h of 1.52 (1.45-1.58), 1.65 (1.58-1.72), and 1.84 (1.75-1.93), compared to those of adults 18 to 64 years (all p < 0.001). These findings remained consistent in the subsets of attendances leading to hospital admission and those leading to discharge from ED.

DISCUSSION AND CONCLUSION

In this real-world cohort study, older adults were more likely to have a length of ED stay ≥ 4 h, with the oldest old having the highest risk. ED target times should take into account age of attendees.

Prevalence and pattern of geriatric emergencies in a teaching hospital of North India

Introduction

Changing demographic patterns worldwide and improvement in healthcarehas contributed to increasing visits to the emergency department byelderly patients. Geriatric patients usually have multiple co-morbidities and declining physiological functional status. This complex interplay of various factors requires a specific and curated approach from the emergency physicians. Our aim was to study the pattern and prevalence of geriatric emergencies and the profile of infectious and non-infectious causes of fever in geriatric population in our tertiary care center.

Materials and Methods

This retrospective descriptive study was carried out at a tertiary care hospital of north India and included all patients aged more than 18 years who visited the emergency department over a period of six months (July 2018 to December 2018). Detailed data regarding demographic, clinical and diagnosis was obtained retrospectively from the hospital records system. The patients were divided into two groups, age less than 60 years and elderly patients more than 60 years of age for comparison.

Results

A total of 24768 patients above the age of 18 years visited the emergency department over a period of six months. Out of which 5399 (27.5%) patients belonged to the geriatric age group more than 60 years of age. 2474 (45.8%) geriatric age group patientswere triaged to critical areas level one and level two as compared to 4668 (24.1%) patients aged less than 60 years. Ninety (1.8%) geriatric patients succumbed to death as compared to 77 (0.4%) patients aged less than 60 years. 651 (21.9%) geriatric patients were shifted to intensive care unit as opposed to 1038 (14.8%) patients of the younger age group.226 (4.2%) geriatric patients presented with fever in the emergency department.116 (73.4%) patients having underlying co-morbidities , had fever due to infectious causes whereas 42 ( 26.5%) patients had fever due to non-infectious causes.

Conclusion

The clinical presentation mortality and morbidity pattern of geriatric patients differs significantly from that of younger population and requires a customized approach and dedicated emergency setups.

Elderly People's Access to Emergency Departments during the COVID-19 Pandemic: Results from a Large Population-Based Study in Italy

Across the world, people have avoided seeking medical attention during the coronavirus pandemic, resulting in a marked reduction in emergency department (ED) visits. This retrospective cohort study examines in detail how the present pandemic affects ED use by the elderly. The regional database on ED visits in Veneto (northeastern Italy) was consulted to extract anonymous data on all ED visits during 2019 and 2020, along with details concerning patients' characteristics (access mode, triage code, chief complaint, and outcome). A year-on-year comparison was drawn between 2019 and 2020. There was a 25.3% decrease in ED visits in 2020 compared to the previous year. The decrease ranged from -52.4% in March to -18.4% in September when comparing the same months in the two years. This decrease started in late February 2020, with the lowest numbers of visits recorded in March and April 2020 (during the "first wave" of the COVID-19 pandemic in Italy), and in the autumn (during the "second wave"). The proportion of visits to the ED by ambulance has increased sharply since March 2020, and patients arrived more frequently with severe conditions (red or yellow triage tags) that often required a hospitalization. The greatest decrease was in fact observed for non-urgent complaints. This decreased concerned a wide range of conditions, including chest pain and abdominal pain. The sharp reduction observed in the present study is unlikely to be attributed entirely to the effect of lockdown measures. Individual psychological and media-induced fear of contagion most likely played a relevant role in leading people to avoid seeking medical attention.

Predictors of Emergency Room Access and Not Urgent Emergency Room Access by the Frail Older Adults

Background: Emergency rooms (ERs) overcrowded by older adults have been the focus of public health policies during the recent COVID-19 outbreak too. This phenomenon needed a change in the nursing care of older frail people. Health policies have tried to mitigate the frequent use of ER by implementing community care to meet the care demands of older adults. The present study aimed to investigate the predictors of emergency room access (ERA) and not-urgent emergency room access (NUERA) of community-dwelling frail older adults in order to provide an indication for out-of-hospital care services.

Method: Secondary analysis of an observational longitudinal cohort study was carried out. The cohort consisted of 1,246 community-dwelling frail older adults (over 65 years) in the Latium region in Italy. The ER admission rate was assessed over 3 years from the administration of the functional geriatric evaluation (FGE) questionnaire. The ordinal regression model was used to identify the predictors of ERA and NUERA. Moreover, the ERA and NUERA rate per 100 observations/year was analyzed.

Results: The mean age was 73.6 (SD ± 7.1) years, and 53.4% were women. NUERAs were the 39.2% of the ERAs; robust and pre-frail individuals (79.3% of the sample) generated more than two-third of ERAs (68.17%), even if frails and very frails showed the higher ER rates per observation/year. The ordinal logistic regression model highlighted a predictive role on ERAs of comorbidity (OR = 1.13, p < 0.001) and frailty level (OR = 1.29; p < 0.001). Concerning NUERAs, social network (OR 0.54, P = 0.015) and a medium score of pulmo-cardio-vascular function (OR 1.50, P = 0.006) were the predictors.

Conclusion: Comorbidity, lack of social support, and functional limitations increase both ERA and NUERA rates generated by the older adult population. Overall, bio-psycho-social frailty represents an indicator of the frequency of ERAs. However, to reduce the number of ERAs, intervention should focus mainly on the robust and pre-frail needs for prevention and care.

Factors to improve quality for older patients in the emergency department: a qualitative study of patient trajectory

BACKGROUND

Managing older people in the emergency department remains a challenge. We aimed to identify the factors influencing the care quality of older patients in the emergency department, to fine-tune future interventions for older people, considering the naturalistic context of the ED.

METHODS

This is a qualitative study of some 450 h of observations performed in three emergency departments selected for their diverse contexts. We performed seventy observations of older patient trajectories admitted to the emergency department. Themes were extracted from the material using an inductive reasoning approach, to highlight factors positively or negatively influencing management of patient's trajectories, in particular those presenting with typically geriatric syndromes.

RESULTS

Four themes were developed: no geriatric flow routine; risk of discontinuity of care; unmet basic needs and patient-centered care; complex older patients are unwelcome in EDs.

CONCLUSIONS

The overall process of care was based on an organ- and flow-centered paradigm, which ignored older people's specific needs and exposed them to discontinuity of care. Their basic needs were neglected and, when their management slowed the emergency department flow, older people were perceived as unwelcome. Findings of our study can inform the development of interventions about the influence of context and organizational factors.

Risk for short-term undesirable outcomes in older emergency department users: Results of the ER2 observational cohort study

BACKGROUND

The "Emergency Room Evaluation and Recommendations" (ER2) is a clinical tool designed to determine prognosis for the short-term Emergency Department (ED) undesirable outcomes including long length of stay (LOS) in ED and in hospital, as well as the likelihood of hospital admission during an index ED visit. It is also designed to guide appropriate and timely tailor-made geriatric interventions. This study aimed to examine whether ER2 assessment part was: 1) usable by ED healthcare workers (e.g. nurses) and 2) scoring system associated with long LOS in ED and in hospital, as well as hospital admission in older ED users on stretchers.

METHODS

Based on an observational, prospective and longitudinal cohort study 1,800 participants visiting the ED of the Jewish General Hospital (Montreal, Quebec, Canada) were recruited between September and December 2017. ER2 assessment determined three risk-levels (i.e., low, medium and high) for short-term ED undesirable outcomes. The rate of ER2 digital form completed, the time to fill ER2 items and obtain ER2 risk-levels, the LOS in ED and in hospital, and hospital admission were used as outcomes.

RESULTS

ER2 was usable by ED nurses in charge of older ED users. High-risk group was associated with both increased ED stay (coefficient of regression β = 3.81 with P≤0.001) and hospital stay (coefficient of regression β = 4.60 with P = 0.002) as well as with hospital admission (HR = 1.32 with P≤0.001) when low ER2 risk level was used as referent level. Kaplan-Meier distributions showed that the three risk groups of participants differed significantly (P = 0.001). Those with high-risk level (P≤0.001) were discharged later from hospital to a non-hospital location compared to those with low risk. There was no significant difference between those classified in low-risk and in medium-risk groups (P = 0.985) and those in medium and high-risk groups (P = 0.096).

CONCLUSION

The ER2 assessment part is usable in daily practice of ED care and its risk stratifications may be used to predict adverse outcomes including prolonged LOS in ED and in hospital as well as hospital admission.

Root causes and preventability of emergency department presentations of older patients: a prospective observational study

OBJECTIVE

More older patients are presenting to the emergency department (ED). It is important to know why these patients present and if the ED is the best place for them to receive the care they need. The primary aim of this study was to identify organisational-related, technical-related, healthcare worker-related and patient-related factors leading to ED presentations of older patients. The secondary aim was to determine patients' and caregivers' perspectives on what kinds of ED presentations are potentially preventable.

DESIGN

This is a prospective observational study. A root cause analysis was performed by the Prevention and Recovery Information System for Monitoring and Analysis method. It used basic administrative data collected from patient records and interviews of patients, general practitioners (GPs) and physicians at the ED.

SETTING

The ED of an academic hospital in the Netherlands.

PARTICIPANTS

100 older patients (aged ≥70 years) who attended the ED between November 2017 and March 2018.

RESULTS

In 100 patients presenting to the ED, 159 factors that contributed to presentation were identified; most of these factors were related to underlying diseases (59%) and patient-related factors (18%). These presentations were considered potentially preventable by 23% of the physicians at the ED and 21% of the GPs, but only 10% of the patients. In only four cases was there overall agreement between the patients and the healthcare workers.

CONCLUSION

The most frequent underlying factors contributing to an ED presentation in older patients are disease-related and patient-related. The low percentage of ED presentations considered potentially preventable shows that a 'preventable ED presentation' is difficult to define and therefore interventions to reduce them are unlikely to be simple. Novel solutions within the acute care pathway are required in order to deliver care of optimal quality and safety to older patients.

Prevalence, determinants and practical implications of inappropriate hospitalizations in older subjects: A prospective observational study

In a context of high demand for hospital services among older people, we aimed to assess the rate and determinants of inappropriate hospitalizations of older patients, and to what extent they were associated with inappropriate hospital stay. This prospective observational multicentre study evaluated a random sample of consecutive patients aged ≥ 70 years accessing the Emergency Department (ED) of two Italian tertiary hospitals. A standardized comprehensive geriatric assessment was carried out in each patient, including the Blaylock Risk Assessment Screen Scale (BRASS) for identification of patients at risk of difficult discharge. Inappropriate hospitalization was defined by the ED physician when patients did not necessitate hospital-provided procedures but was due to social reasons or lack of an alternative care-setting. Among 1877 patients (median age 80.7 years, 50.1% male), with a high prevalence of functional dependence and social isolation (around 30% and 25%, respectively), 767 (40.9%) were hospitalized. Incidence of inappropriate hospitalization was 14.6% (95% CI 12.1%-17.1%) and was associated with moderate-high risk of difficult discharge at BRASS (OR = 1.98, 95% CI 1.16-3.39, p = 0.013) and the presence of dementia with behavioural disorders (OR = 1.79, 95% CI 1.10-2.91, p = 0.020). Compared with patients appropriately admitted, inappropriate hospitalizations had shorter length of hospital stay but accounted for 1059/9154 days of stay (11.6%). Inappropriate hospitalizations occurred in less than 15% of cases, mainly accounted for by patients no longer manageable at home, but contributed to the greatest proportion of inappropriate hospital stay. These findings highlight the need of implementing appropriate home-care services and ensuring rapid access to suitable care-facilities for community-dwelling frail older patients.

Predicting Unscheduled Emergency Department Return Visits Among Older Adults: Population-Based Retrospective Study

Background

Unscheduled emergency department return visits (EDRVs) are key indicators for monitoring the quality of emergency medical care. A high return rate implies that the medical services provided by the emergency department (ED) failed to achieve the expected results of accurate diagnosis and effective treatment. Older adults are more susceptible to diseases and comorbidities than younger adults, and they exhibit unique and complex clinical characteristics that increase the difficulty of clinical diagnosis and treatment. Older adults also use more emergency medical resources than people in other age groups. Many studies have reviewed the causes of EDRVs among general ED patients; however, few have focused on older adults, although this is the age group with the highest rate of EDRVs.

Objective

This aim of this study is to establish a model for predicting unscheduled EDRVs within a 72-hour period among patients aged 65 years and older. In addition, we aim to investigate the effects of the influencing factors on their unscheduled EDRVs.

Methods

We used stratified and randomized data from Taiwan’s National Health Insurance Research Database and applied data mining techniques to construct a prediction model consisting of patient, disease, hospital, and physician characteristics. Records of ED visits by patients aged 65 years and older from 1996 to 2010 in the National Health Insurance Research Database were selected, and the final sample size was 49,252 records.

Results

The decision tree of the prediction model achieved an acceptable overall accuracy of 76.80%. Economic status, chronic illness, and length of stay in the ED were the top three variables influencing unscheduled EDRVs. Those who stayed in the ED overnight or longer on their first visit were less likely to return. This study confirms the results of prior studies, which found that economically underprivileged older adults with chronic illness and comorbidities were more likely to return to the ED.

Conclusions

Medical institutions can use our prediction model as a reference to improve medical management and clinical services by understanding the reasons for 72-hour unscheduled EDRVs in older adult patients. A possible solution is to create mechanisms that incorporate our prediction model and develop a support system with customized medical education for older patients and their family members before discharge. Meanwhile, a reasonably longer length of stay in the ED may help evaluate treatments and guide prognosis for older adult patients, and it may further reduce the rate of their unscheduled EDRVs.

Emergency room evaluation and recommendations for older emergency department users: results of the ER2 experimental study

PURPOSE

The study aims to examine whether the use of "emergency room evaluation and recommendations" (ER²) tool in daily ED practice reduces the length of stay in ED and hospital, and hospital admission in older patients visiting ED on stretcher.

METHODS

A total of 3931 older patients visiting ED of the Jewish General Hospital (Montreal, Quebec, Canada) on stretcher were recruited in this non-randomized, pre-post intervention, single arm, prospective and longitudinal open-label trial. ED staff and patients were blinded of the ER² score and patients received usual ED care over the observational phase, whereas ED staff were informed about the ER² score and patients had usual care plus interventions based on tailor-made geriatric recommendations during the interventional phase. The length of stay in ED and in hospital, and hospital admission were the outcomes.

RESULTS

The ER² recommendations were associated with increased length of stay in ED (β = 2.94 with P ≤ 0.001) and decreased length of stay in hospital (β = - 2.07 with P = 0.011). No effect was found for hospital admission (Odd Ratio (OR) = 0.92 with P = 0.182).

CONCLUSION

Emergency room evaluation and recommendations (ER²) tool had mixed effects. Shorter hospital stay has been reported for older ED users hospitalized, but increased ED stay and no effects on hospital admission were found.

A qualitative study of home care client and caregiver experiences with a complex cardio-respiratory management model

Background

Home care clients are typically older and have some degree of medical, physical, cognitive or social conditions that require formal or informal support to promote healthy aging in the community. Home care clients contribute a significant proportion of health service use, including emergency department visits. The DIVERT-CARE trial introduced a cardio-respiratory management model to improve client motivation, symptoms and rates of unwarranted health service use. Our objective was to explore the perceptions and experiences of individuals who participated in the DIVERT-CARE self-management support and education intervention.

Methods

A qualitative study was nested within a pragmatic randomized control trial and conducted following a 15-week multi-component cardio-respiratory intervention. A phenomenological descriptive design was employed using thematic analysis. Post-intervention, clients and their caregivers were invited to participate in a semi-structured telephone interview. Interview questions were designed to elicit the experience with the intervention components.

Results

A total of 29 interviews were completed from June 2018 to March 2020 from participants in Ontario, Newfoundland, and British Columbia. Three themes were identified; self-care trajectory and burden of responsibility, learning and behaviour change, and feeling connected pre-emptively to care providers, the information and medical advice, and connection through the therapeutic relationship.

Conclusions

Home care clients experience unique challenges in managing cardio-respiratory related chronic disease. Home-based interventions fostered a therapeutic relationship of connectedness while equipping clients with necessary knowledge and skills. These results inform recommendations for community nursing, and home-based self-management supports for older community-residing individuals.

Mind the caretaker: ED referrals of community-dwelling older adult patients by their primary caregivers are accurate

BACKGROUND

ED referral of older adults on the initiative of their family or paid live-in caregiver is common but not previously studied.

METHODS

ED-presenting community-dwelling patients ≥65 years were studied, emphasizing the referring agent, and correct (admitted or discharged +changed diagnosis/treatment) vs. incorrect referral (discharged, no change made).

RESULTS

Of 448 consecutive patients (median age 83 years), 231 were referred by their primary physician (PCP) (73% admitted, 17% discharged +change). 117 ED referrals were initiated by their family (78% admitted, 6% discharged +change), and 100 by their paid caregiver (66% admitted, 21% discharged +change). Differences were non-significant, as was the distribution of main diagnoses.

CONCLUSIONS

ED referral of older adults from the community by laymen who know the patient well (family or caregiver) is non-inferior to a referral by their PCP. ED physicians should regard non-physician ED presentations as seriously as a referral by a physician, pending confirmation in future studies.

Value of biomarkers in predicting mortality in older medical emergency department patients: a Dutch prospective study

OBJECTIVE

Older emergency department (ED) patients are at high risk of mortality, and it is important to predict which patients are at highest risk. Biomarkers such as lactate, high-sensitivity cardiac troponin T (hs-cTnT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), D-dimer and procalcitonin may be able to identify those at risk. We aimed to assess the discriminatory value of these biomarkers for 30-day mortality and other adverse outcomes.

DESIGN

Prospective cohort study. On arrival of patients, five biomarkers were measured. Area under the curves (AUCs) and interval likelihood ratios (LRs) were calculated to investigate the discriminatory value of the biomarkers.

SETTING

ED in the Netherlands.

PARTICIPANTS

Older (≥65 years) medical ED patients, referred for internal medicine or gastroenterology.

PRIMARY AND SECONDARY OUTCOME MEASURES

30-day mortality was the primary outcome measure, while other adverse outcomes (intensive care unit/medium care unit admission, prolonged length of hospital stay, loss of independent living and unplanned readmission) were the composite secondary outcome measure.

RESULTS

The median age of the 450 included patients was 79 years (IQR 73-85). In total, 51 (11.3%) patients died within 30 days. The AUCs of all biomarkers for prediction of mortality were sufficient to good, with the highest AUC of 0.73 for hs-cTnT and NT-proBNP. Only for the highest lactate values, the LR was high enough (29.0) to be applicable for clinical decision making, but this applied to a minority of patients. The AUC for the composite secondary outcome (intensive and medium care admission, length of hospital stay >7 days, loss of independent living and unplanned readmission within 30 days) was lower, ranging between 0.58 and 0.67.

CONCLUSIONS

Although all five biomarkers predict 30-day mortality in older medical ED patients, their individual discriminatory value was not high enough to contribute to clinical decision making.

Prevalence, severity, and nature of risk factors associated with drug-drug interactions in geriatric patients receiving cancer chemotherapy: A prospective study in a tertiary care teaching hospital

INTRODUCTION

Polypharmacy increases hazard of drug-drug interactions(DDIs), hospitalization, treatment toxicity, and mortality in elderly individuals with cancer. The present study explores and analyzes prevalence and severity of DDIs in geriatric cancer patients subjected to anticancer chemotherapy, their mechanisms, stratification of severity, and correlation between DDI risk and number of medications taken.

METHODS

This was a cross-sectional study conducted between January-July 2019 at the Medical Oncology/Hematology and Radiation-Oncology Departments, All India Institute of Medical Sciences(AIIMS) Rishikesh. The study included a convenience sampling of 126 geriatric cancer patients.

RESULTS

126 patients were enrolled in present study. DDIs were identified in 97.6% of elderly cancer patients, and 88.9% had at least one DDI with antineoplastic medications. Highest number of DDIs involving antineoplastic medications in any given patient was 12. DDIs involving medications used for treatment of non-cancerous diseases were observed in 83.3% of patients; highest number of interactions identified in any given patient was 15. Out of 473 interactions, 237(50.1%) DDIs were attributable to pharmacodynamic mechanisms of action. 126(27%) of DDIs involved pharmacokinetic mechanisms and 110(23.6%) involved unknown mechanisms. In this present study, total number of DDIs could be positively correlated with total number of medications and number of health problems.

CONCLUSIONS

Geriatric cancer patients are at high risk of DDIs ascribable to polypharmacy. Physicians may utilize online DDI checking softwares to alert themselves, characterize potential DDIs, and modify medications judiciously. An integrative and algorithmic approach with inclusion of geriatricians, oncologists, cardiologists, general practitioners, and clinical pharmacologists/ pharmacists is imperative to optimize drug therapy.

Profiles of Frequent Geriatric Users of Emergency Departments: A Latent Class Analysis

BACKGROUND/OBJECTIVES

Frequent geriatric users of emergency departments (EDs) represent a complex and heterogeneous population. Identifying their specific subgroups would allow the development of interventions better customized to their needs and characteristics. Thus, this study aimed to develop profiles of frequent geriatric ED users using the individual characteristics of patients.

DESIGN

This was a retrospective cohort study.

SETTING

Databases from the Régie de l'assurance maladie du Québec (RAMQ) were utilized. PARTICIPANTSThis study included individuals aged 65 years or older living in the community in the Province of Quebec (Canada), who consulted in an ED at least four times in the year after an ED index date (an ED visit, chosen randomly, during an index period of January 1, 2012 to December 31, 2013) and who had received a diagnosis of ambulatory care-sensitive conditions (ACSCs) in the 2 years preceding the index date.

MEASUREMENTS

A latent class analysis was used to identify subgroups of frequent geriatric ED users according to their individual characteristics, including ACSC type, dementia, mental health disorders, cancer diagnosis, and comorbidity index.

RESULTS

The study cohort consisted of 21,393 frequent geriatric ED users. Four groups of frequent geriatric ED users were identified: people with low comorbidity (39.0%), comprising the individuals with the lowest number of physical and mental health conditions; people with cancer (32.7%); people with pulmonaryand cardiac diseases (18.1%); and people with dementia or mental health disorders (10.2%), composed of individuals with the highest proportion of common and severe mental health disease, as well as dementia. This group accounts for the highest use of overall healthcare services.

CONCLUSION

These profiles will be useful in developing customized interventions addressing the needs of each subgroup of frequent geriatric ED users. More research is needed to bridge the remaining gaps, especially regarding the healthiest frequent geriatric users of EDs.
