Constipation: a neglected condition in older emergency department patients.

Constipation and fecal impaction are common issues with the potential for significant morbidity in older people presenting to the Emergency Department (ED). While many of these patients present with classical symptoms of constipation or fecal impaction, atypical presentations are also frequent. These atypical presentations may include paradoxical diarrhea, fecal incontinence, urinary retention or overflow incontinence, hyperactive or hypoactive delirium, anorexia/dysphagia, and syncope. In addition, various clinical conditions (such as dementia, Parkinson's disease, dehydration, and hypothyroidism) and medications (such as opiate analgesics, anticholinergics, diuretics, calcium channel blockers, anti-parkinsonian drugs, and oral iron supplements) are associated with constipation and should be considered during the diagnostic process in the ED. This narrative review specifically focuses on the prevalence, presentation, diagnoses, and management of constipation in older ED patients.

Core requirements of frailty screening in the emergency department: an international Delphi consensus study.

INTRODUCTION: Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study. METHODS: A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements for Round 1 (August-September 2021). Four main themes identified were: (i) principles of frailty screening, (ii) practicalities and logistics, (iii) frailty domains and (iv) frailty risk factors. RESULTS: In Round 1, 13/56 statements (23%) were accepted. Following feedback, 22 new statements were created and 35 were re-circulated in Round 2 (October 2021). Of these, 19 (54%) were finally accepted. It was agreed that ideal frailty screens should be short (<5 min), multidimensional and well-calibrated across the spectrum of frailty, reflecting baseline status 2-4 weeks before presentation. Screening should ideally be routine, prompt (<4 h after arrival) and completed at first contact in ED. Functional ability, mobility, cognition, medication use and social factors were identified as the most important variables to include. CONCLUSIONS: Although a clear consensus was reached on important requirements of frailty screening in ED, and variables to include in an ideal screen, more research is required to operationalise screening in clinical practice.

Sensibility and Specificity of the VitaPCR™ SARS-CoV-2 Assay for the Rapid Diagnosis of COVID-19 in Older Adults in the Emergency Department.

(1) Background: During the COVID-19 pandemic, rapid and reliable diagnostic tools are needed for detecting SARS-CoV-2 infection in urgent cases at admission to the hospital. We aimed to assess the performances of the rapid molecular VitaPCR™ test (Menarini Diagnostics) in a sample of older adults admitted to the Emergency Department of two Italian hospitals (2) Methods: The comparison between the rapid VitaPCR™ and the RT-PCR was performed in 1695 samples. Two naso-pharyngeal swab samplings from each individual were obtained and processed using the VitaPCR™ and the RT-PCR for the detection of SARS-CoV-2 (3) Results: VitaPCR™ exhibited good precision (<3% CV) and an almost perfect overall agreement (Cohen's K = 0.90) with the RT-PCR. The limit of detection of the VitaPCR™ was 4.1 copies/µL. Compared to the RT-PCR, the sensitivity, the specificity, and the positive and negative predictive values of VitaPCR™ were 83.4%, 99.9%, 99.2% and 98.3%, respectively (4) Conclusions: The VitaPCR™ showed similar sensitivity and specificity to other molecular-based rapid tests. This study suggests that the VitaPCR™ can allow the rapid management of patients within the Emergency Department. Nevertheless, it is advisable to obtain a negative result by a RT-PCR assay before admitting a patient to a regular ward.

Prevalence and management of dysphagia in nursing home residents in Europe and Israel: the SHELTER Project.

BACKGROUND: Dysphagia is a frequent condition in older nursing home residents (NHRs) which may cause malnutrition and death. Nevertheless, its prevalence is still underestimated and there is still debate about the appropriateness and efficacy of artificial nutrition (AN) in subjects with severe dysphagia. The aim is to assess the prevalence of dysphagia in European and Israeli NHRs, its association with mortality, and the relationship of different nutritional interventions, i.e. texture modified diets and AN-with weight loss and mortality. METHODS: A prospective observational study of 3451 European and Israeli NHRs older than 65 years, participating in the SHELTER study from 2009 to 2011, at baseline and after 12 months. All residents underwent a standardized comprehensive evaluation using the interRAI Long Term Care Facility (LTCF). Cognitive status was assessed using the Cognitive Performance Scale (CPS), functional status using Activities of Daily Living (ADL) Hierarchy scale. Trained staff assessed dysphagia at baseline by clinical observation. Data on weight loss were collected for all participants at baseline and after 12 months. Deaths were registered by NH staff. RESULTS: The prevalence of dysphagia was 30.3%. During the one-year follow-up, the mortality rate in subjects with dysphagia was significantly higher compared with that of non-dysphagic subjects (31.3% vs 17.0%,p = 0,001). The multivariate analysis showed that NHRs with dysphagia had 58.0% higher risk of death within 1 year compared with non-dysphagic subjects (OR 1.58, 95% CI, 1.31-1.91). The majority of NHRs with dysphagia were prescribed texture modified diets (90.6%), while AN was used in less than 10% of subjects. No statistically significant difference was found concerning weight loss and mortality after 12 months following the two different nutritional treatments. CONCLUSIONS: Dysphagia is prevalent among NHRs and it is associated with increased mortality, independent of the nutritional intervention used. Noticeably, after 12 months of nutritional intervention, NHRs treated with AN had similar mortality and weight loss compared to those who were treated with texture modified diets, despite the clinical conditions of patients on AN were more compromised.

Ecological factors associated with Emergency Department use by older people in Italy.

BACKGROUND: Many studies investigated factors associated with overuse of Emergency Department (ED) by older people. However, there is little evidence of how a better access to long-term care services can affect ED visit rates. Therefore, we estimated the association between ED use and contextual (distance to closest ED), need (priority level at admission and care deprivation), predisposing (socio-economic conditions) and enabling factors (availability of health services) at the municipal level. METHODS: We investigated ED visit rates by comparing the older population (aged 75 and more) to those aged less than 75 years among 233 municipalities and 13 health districts in the Marche Region, Central Italy. Administrative data were enriched by spatial dimensions. The outcomes were analysed using t-tests and ANOVA, while OLS and multilevel regressions have been used to identify independent correlates of ED visit rates. RESULTS: Mean ED visit rate was 56.3% and 25.3% among older people and the rest of the population (< 75 years), respectively. The multivariate analysis for older people showed that the presence of an ED within the municipality and living alone were positively associated with ED use, whereas greater availability of nursing homes was negatively associated. For general population (< 75 years), distance to closest ED, economic deprivation and bigger hospitals were negatively associated with ED visits. CONCLUSIONS: Our study shows that interventions to reduce frequent ED use by older people should include the availability of long-term care facilities in the area. As population ageing is progressing, our results suggest that investing in alternative care options for older people with long-term care needs might have the beneficial impact of reducing the overall ED rates and improving quality and appropriateness of care.

Non-pharmacological approaches in the prevention of delirium.

PURPOSE: Delirium is a geriatric syndrome often occurring in hospitalized older patients. Since there is no established treatment for delirium, it is important to identify patients at high risk to develop it, to implement preventive interventions. As yet, there is no conclusive evidence that different drugs classes are effective in preventing delirium; whereas they have potentially severe adverse effects. The non-pharmacological interventions to prevent delirium are quite diverse, ranging from single-component interventions to complex multi-component interventions that deploy simultaneous care for different risk factors. The aim of this review was to summarize the evidence concerning the efficacy of non-pharmacological interventions in delirium prevention in older adults. METHODS: Extensive PubMed search using the following keywords with different combinations: delirium (with or without "prevention") AND non-pharmacological; interventions; multi-component. The reference lists of retrieved articles and, most of all, systematic reviews and meta-analysis, were screened for additional pertinent studies. RESULTS: The evidence for non-pharmacological, multi-component interventions is sufficiently robust for clinical practice recommendations to be formulated. However, no conclusive effects have been demonstrated on outcomes more distal to delirium occurrence and for single-component interventions. CONCLUSIONS: The majority of studies that investigated non-pharmacological prevention of delirium were designed as explanatory studies aimed at demonstrating the efficacy of the intervention. In the future, pragmatic studies should be conducted, in which the aim is to investigate effectiveness in usual clinical practice.

Is polypharmacy an independent risk factor for adverse outcomes after an emergency department visit?

This study aimed at verifying the role of polypharmacy as an independent risk factor for adverse health outcomes in older emergency department (ED) patients. This was a large (n = 2057) sample of older ED patients (≥65 years) participating in an observational cohort study. Polypharmacy and excessive polypharmacy were defined as having 6-9 drug prescriptions and 10 or more drug prescriptions in the last 3 months, respectively. The total number of medication prescriptions was also available. Outcome measures were in-hospital mortality; 30-day ED return; ED revisit, hospital admission, and mortality at 6 months. Logistic and Cox regression models as well as receiver operating characteristic curves using the Youden index and the area under the curve were calculated. Polypharmacy and excessive polypharmacy were present in 624 (30.3 %) and 367 (17.8 %) subjects, respectively. The mean number of prescriptions in the last 3 months was 5.7 (range 0-25) drugs. Polypharmacy and, particularly, excessive polypharmacy were constantly and independently associated with worse outcomes. A cut-off of 6 had the highest value of the Youden Index in predicting the majority of the adverse outcomes considered. Polypharmacy and excessive polypharmacy are independent risk factors for adverse health outcomes after an ED visit. Further studies are needed to clarify whether drug related issues (such as non-compliance, inappropriate or suboptimal prescribing, adverse drug reactions, and drug-drug or drug-disease interactions) or underlying multimorbidity and disease severity, as well as clinical complexity and frailty, are responsible for the negative outcomes associated with polypharmacy.

Pattern of use and presenting complaints of older patients visiting an Emergency Department in Italy.

BACKGROUND AND AIMS: The number of older persons admitted to the Emergency Department (ED) is dramatically increasing due to their complex medical and social problems, which in turn lead to longer clinical evaluation times and increased use of resources compared to younger adults. However, scant data are available for Italian EDs. Similarly, no data are available about the reasons to ED visit and its role in determining the ED utilization pattern. The study aimed at describing the pattern of ED use by older patients and main presenting complaints. METHODS: Cross-sectional descriptive study of 5,826 ED patients in the city of Fano (Italy). Identifiers and triage, clinical and social data were collected. Presenting complaints as recorded by triage nurses have been recoded according to the Canadian Emergency Department Information System list version 1.1. Data were analyzed comparing older patients (more than 65 years-old) with younger adults (less than 65 years-old). RESULTS: The prevalence of ED visits by older adults was 23.9 %. Their visits were characterized by higher emergency levels, admission rate and length of ED stay. Trauma was the main reason for ED presentation, especially among young adults, but elderly trauma patients were more frequently admitted because of hip fracture. Dyspnea and abdominal pain were the most frequent non-trauma presenting complaints among geriatric patients and represented the main causes for admission. CONCLUSIONS: Older adults use the ED appropriately also in Italy. Trauma with complications (fracture) and various presenting complaints underlying medical problems accounted for more than 50 % of ED visits and hospital admissions.

Risk stratification of older patients in the emergency department: comparison between the Identification of Seniors at Risk and Triage Risk Screening Tool.

BACKGROUND AND OBJECTIVES: The increasing number of elderly patients accessing emergency departments (ED) requires use of validated, rapid assessment instruments. The aim of this study was to compare the Identification of Seniors at Risk (ISAR) and Triage Risk Screening Tool (TRST), based on direct patient evaluation. RESEARCH DESIGN AND SUBJECTS: This study was a prospective observational study with 6 months follow-up. Subjects were 2,057 residents in the Marche Region, aged 65 or more years, accessing the first-level ED of a geriatric hospital in Ancona, Italy, over a 6-month period. METHODS: ISAR and TRST were administered at triage by nurse. Outcomes were in need of hospital admission and mortality at the index ED access, early (within 30 days) and late ED revisit, hospitalization, and death in 6 months. RESULTS: ISAR (cutoff of≥2) was positive in 68% of patients, whereas 64% were TRST-positive. The two scores were significantly correlated and had similar areas under the receiver operating characteristic (ROC) curves in predicting hospital admission (ISAR, 0.68; TRST, 0.66) and mortality (ISAR, 0.74; TRST, 0.68), as well as early ED revisit (ISAR, 0.63; TRST, 0.61). In the 6-month follow-up of patients discharged alive, the tools predicted comparably ED return visit (ISAR, 0.60; TRST, 0.59), hospital admission (ISAR, 0.63; TRST, 0.60), and mortality (ISAR, 0.74; TRST, 0.73). A similar performance was observed in the subgroup of participants discharged directly from the ED. CONCLUSIONS: Risk stratification of elderly ED patients with ISAR or TRST is substantially comparable for selecting elderly ED patients who could benefit from geriatric interventions. ISAR had slightly higher sensitivity and lower specificity than TRST.

Prognostic stratification of elderly patients in the emergency department: a comparison between the "Identification of Seniors at Risk" and the "Silver Code".

BACKGROUND: The increasing number of elderly patients accessing emergency departments (EDs) requires use of validated assessment tools. We compared the Identification of Seniors at Risk (ISAR), using direct patient evaluation, with the Silver Code (SC), based on administrative data. METHODS: Subjects aged 75+ years accessing a geriatric ED over an 8-month period were enrolled. Outcomes were need for hospital admission and mortality at the index ED access, ED return visit, hospitalization, and death at 6 months. RESULTS: Of 1,632 participants (mean age 84 ± 5.5 years), 75% were ISAR positive, and the sample was homogeneously distributed across the four SC risk categories (cutoffs of 0-3, 4-6, 7-10, and 11+). The two scores were mildly correlated (r = .350, p < .001) and had a similar area under the receiver-operating characteristic curve in predicting hospital admission (ISAR: 0.65, SC: 0.63) and mortality (ISAR: 0.72, SC: 0.70). ISAR-positive subjects were at greater risk of hospitalization and death (odds ratio 2.68 and 5.23, respectively, p < .001); the risk increased across SC classes (p < .001). In the 6-month follow-up of discharged patients, the tools predicted similarly ED return visit, hospital admission, and mortality. The SC predicted these outcomes even in participants not hospitalized at the index ED access. CONCLUSIONS: Prognostic stratification of elderly ED patients with the SC is comparable with that obtained with direct patient evaluation. The SC, previously validated in hospitalized patients, predicts ED readmissions and future hospitalizations even in patients discharged directly from the ED.

Adverse drug events as a cause of hospitalization in older adults.

Older adults are about four to seven times more likely than younger persons to experience adverse drug events (ADEs) that cause hospitalization, especially if they are women and take multiple medications. The prevalence of drug-related hospitalizations has been reported to be as high as 31%, with large heterogeneity between different studies, depending on study setting (all hospital admissions or only acute hospital admissions), study population (entire hospital, specific wards, selected population and/or age groups), type of drug-related problem measured (adverse drug reaction or ADE), method of data collection (chart review, spontaneous reporting or database research) and method and definition used to detect ADEs. The higher risk of drug-related hospitalizations in older adults is mainly caused by age-related pharmacokinetic and pharmacodynamic changes, a higher number of chronic conditions and polypharmacy, which is often associated with the use of potentially inappropriate drugs. Other factors that have been involved are errors related to prescription or administration of drugs, medication non-adherence and inadequate monitoring of pharmacological therapies. A few commonly used drugs are responsible for the majority of emergency hospitalizations in older subjects, i.e. warfarin, oral antiplatelet agents, insulin and oral hypoglycaemic agents, central nervous system agents. The aims of the present review are to summarize recent evidence concerning drug-related hospitalization in older adults, to assess the contribution of specific medications, and to identify potential interventions able to reduce the occurrence of these drug-related events, as they are, at least partly, potentially preventable.

Predictive validity of the Identification of Seniors At Risk (ISAR) screening tool in elderly patients presenting to two Italian Emergency Departments.

BACKGROUND AND AIMS: Elderly patients presenting to Emergency Departments (ED) have complex health problems and often undergo adverse outcomes after an ED visit. In Canadian ED, the Identification of Seniors At Risk (ISAR) is useful in screening for these aspects. This study evaluated the predictive validity of ISAR for elderly patients presenting to Italian ED. METHODS: Prospective observational study of a cohort of 200 elderly patients presenting to two urban ED in Ancona (Italy). Identifiers and triage, clinical and social data were collected, and the ISAR was administered. The following single outcomes were considered: early (30-day) and late (6-month) ED revisit, frequent ED return, hospital admission, and functional decline. Composite outcomes were: [1] death, long-term care (LTC) placement, functional decline; [2] the same as [1] plus any ED revisit or hospitalization. Odds ratios (OR) and 95% confidence intervals (CI) were calculated. RESULTS: ISAR was positive for 141 (70.5%) subjects, who had high comorbidity, disability and cognitive impairment. ISAR-positive patients had an OR of 4.77 (95% CI, 2.19-10.42) to undergo composite outcome [1] and of 3.46 (95% CI, 1.68-7.15) to experience composite outcome [2]. ISAR also predicted ED revisit and frequent use, hospitalization and functional decline at 6 months. ISAR was also an independent predictor of 6-month mortality (Hazard Ratio 6.9, 95% CI 1.65-29, p=0.008). CONCLUSIONS: ISAR can be used as a screening test to identify Italian elderly ED patients who have an increased 6-month risk of death, LTC placement, functional decline, ED revisit, or hospitalization.

A geriatric emergency service for acutely ill elderly patients: pattern of use and comparison with a conventional emergency department in Italy.

The current disease-oriented, episodic model of emergency care does not adequately address the complex needs of older adults presenting to emergency departments (EDs). Dedicated ED facilities with a specific organization (e.g., geriatric EDs (GEDs)) have been advocated. One of the few GED experiences in the world is described and its outcomes compared with those of a conventional ED (CED). In a secondary analysis of a prospective observational cohort of 200 acutely ill elderly patients presenting to two urban EDs in Ancona, Italy, identifiers and triage, clinical, and social data were collected and the following outcomes considered: early (30-day) and late (6-month) ED revisit, frequent ED return, hospital admission, and functional decline. Death, functional decline, any ED revisit and any hospital admission were also considered as a composite outcome. Odds ratios and 95% confidence intervals (CIs) were calculated. Overall, GED patients were older and frailer than CED patients. The two EDs did not differ in terms of early, late, or frequent ED return or in 6-month hospital admission or functional decline. The mortality rate was slightly but significantly lower in the GED patients (hazard ratio=0.47, 95% CI=0.22-0.99, P=.047). The data suggest noninferiority and, indirectly, a slight superiority for the GED system in the acute care of elderly people, supporting the hypothesis that ED facilities specially designed for older adults may provide better care.

Mini Nutritional Assessment (short form) and functional decline in older patients admitted to an acute medical ward.

BACKGROUND AND AIMS: Protein and/or energy malnutrition is common in hospitalized older patients and is associated with poor outcomes. Among recommended nutritional screening tools, contrasting data exist about the usefulness of the Mini Nutritional Assessment Short-Form (MNA-SF). We evaluated whether the MNA-SF, alone or integrated with serum albumin levels, is a reliable predictor of functional decline in older patients. METHODS: We studied 275 elderly patients (mean age 76.5, 60.7% males) admitted to an acute medical ward of a tertiary-care teaching hospital over a 12-month period. In this observational study, we evaluated nutritional status, with the MNA-SF alone or integrated with albumin. Data were collected at admission and related to laboratory and geriatric assessment features, and length of stay (LOS). Functional decline (defined as a loss >or=10% in terms of Barthel Index score at discharge compared with 2 weeks before admission) was considered as outcome. RESULTS: The MNA-SF estimated 46% patients at risk of malnutrition. These subjects had worse clinical features (lower total cholesterol and albumin levels), longer LOS (13.3 vs 11.2 days, p=0.014) and considerable functional decline (OR 4.25, 95% CI 1.83-9.9, p=0.001). Integrating the MNA-SF with albumin values, we obtained an effective instrument to detect older inpatients with protein-energy malnutrition, at higher risk of undergoing functional decline (OR 16.19, 95% CI 4.68-56.03, p<0.0001). CONCLUSIONS: The MNA-SF is a useful screening tool for hospitalized elders at risk of malnutrition. It is associated with poor clinical outcomes and is able to predict functional decline. Together with hypoalbuminemia, it better identifies patients with true protein-energy malnutrition.

A manual of guidelines to score the modified cumulative illness rating scale and its validation in acute hospitalized elderly patients.

OBJECTIVES: To update previous guidelines to score the Cumulative Illness Rating Scale (CIRS) and test their usefulness in hospitalized elderly patients. DESIGN: The CIRS was scored retrospectively in a cohort of elderly patients followed for 18 months. SETTING: An acute internal medicine ward in an academic tertiary care hospital. PARTICIPANTS: Three hundred eighty-seven patients aged 65 and older. MEASUREMENTS: The CIRS was retrospectively scored for the enrolled patients. Intrarater and interrater reliability were calculated. Two illness severity indices (total score (TSC) and severity (SV)) and one comorbidity index (CM) were obtained. Clinical features and comprehensive geriatric assessment (CGA) variables were also used. All patients underwent an 18-month follow-up for mortality and rehospitalization. RESULTS: Intrarater and interrater reliability of the CIRS scored following the guidelines was good (intraclass correlation coefficients of 0.83 and 0.81, respectively). The TSC, SV, and CM correlated with clinical features (laboratory values, medication usage, and length of in-hospital stay) and CGA variables (cognitive impairment, depression and disability). All three indices were able to predict 18-month mortality and rehospitalization rates. CONCLUSION: This study confirmed the validity of the CIRS as an indicator of health status and demonstrated its ability to predict 18-month mortality and rehospitalization in hospitalized elderly patients. The availability of detailed guidelines for scoring the CIRS can improve its usefulness and facilitate more-widespread use for research and clinical aims.
