Risk factors and risk stratification approaches for delirium screening: A Geriatric Emergency Department Guidelines 2.0 systematic review.

OBJECTIVE: As part of the Geriatric Emergency Department (ED) Guidelines 2.0 project, we conducted a systematic review to find risk factors or risk stratification approaches that can be used to identify subsets of older adults who may benefit from targeted ED delirium screening. METHODS: An electronic search strategy was developed with a medical librarian, conducted in April 2021 and November 2022. Full-text studies of patients ≥65 years assessed for prevalent delirium in the ED were included. Risk of bias was assessed using the McMaster University Clarity Group tool. Outcomes measures pertained to the risk stratification method used. Due to heterogeneity of patient populations, risk stratification methods, and outcomes, a meta-analysis was not conducted. RESULTS: Our search yielded 1878 unique citations, of which 13 were included. Six studies developed a novel delirium risk score with or without evaluation of specific risk factors, six studies evaluated specific risk factors only, and one study evaluated an existing nondelirium risk score for association with delirium. The most common risk factor was history of dementia, with odds ratios ranging from 3.3 (95% confidence interval [CI] 1.2-8.9) to 18.33 (95% CI 8.08-43.64). Other risk factors that were consistently associated with increased risk of delirium included older age, use of certain medications (such as antipsychotics, antidepressants, and opioids, among others), and functional impairments. Of the studies that developed novel risk scores, the reported area under the curve ranged from 0.77 to 0.90. Only two studies reported potential impact of the risk stratification tool on screening burden. CONCLUSIONS: There is significant heterogeneity, but results suggest that factors such as dementia, age over 75, and functional impairments should be used to identify older adults who are at highest risk for ED delirium. No studies evaluated implementation of a risk stratification method for delirium screening or evaluated patient-oriented outcomes.

Dissemination and implementation of age-friendly care and geriatric emergency department accreditation at Veterans Affairs hospitals.

OBJECTIVES: In 2018, the U.S. Department of Veterans Affairs (VA) National Office of Geriatrics and Extended Care (GEC) and the National Emergency Medicine (EM) Program partnered to improve emergency care for older Veterans. A core team disseminated age-friendly models of care via education and standardization of practice with the goal of multisite geriatric emergency department (GED) accreditation. We compare rates of GED screening at VAs with GED implementation to those without. METHODS: Observational evaluation of GED screening of older Veterans (≥65 years) at VA Emergency Departments (ED) from January 2018 to March 2022, during peak pandemic years. Data were extracted from the VA Corporate Data Warehouse of Veteran ED visit encounters to track documented GED screens and Veteran demographic data. Generalized estimating equation models were used to compare screening completion across different levels of GED accreditation, adjusting for potential confounding. RESULTS: During this period, over 1.07 million Veterans ≥ 65 years of age made 4.07 million VA ED visits. Mean (±SD) age was 73.4 (±7.2) years, 96.5% were male, 68% were White, and 89.9% made their index ED visit at a non-GED VA ED. As of early 2022, a total of 50 of 111 VA EDs have achieved or applied for GED accreditation. During early 2022, 8.3% of all visits by older Veterans had at least one GED screen documented; 15% were screened at Levels 1-3 GED versus 2.2% at non-GED facilities. Screens identifying older adults at risk for poor outcomes, for delirium, and for falls had the highest usage rates within VA GEDs. Veterans seen at Level 1 GEDs had a 76-fold greater odds of having a GED screen than at Level 3 GEDs (odds ratio 75.8, 95% confidence interval 72.8-79.0). CONCLUSIONS: Through VA National Office of GEC and EM Program partnership, the VA has created, standardized, and disseminated a GED Model of Care, despite the pandemic. GED accreditation was associated with GED screen implementation, with Level 1 having the highest screening prevalence.

Telehealth for geriatric post-emergency department visits to promote age-friendly care.

OBJECTIVE: To describe a feasibility pilot study for older adults that addresses the digital divide, unmet health care needs, and the 4Ms of Age-Friendly Health Systems via the emergency department (ED) follow-up home visits supported by telehealth. DATA SOURCES AND STUDY SETTING: Data sources were a pre-implementation site survey and pilot phase individual-level patient data from six US Department of Veterans Affairs (VA) EDs. STUDY DESIGN: A pre-implementation survey assessed existing geriatric ED processes. In the pilot called SCOUTS (Supporting Community Outpatient, Urgent care & Telehealth Services), sites identified high-risk patients during an ED visit. After ED discharge, Intermediate Care Technicians (ICTs, former military medics), performed follow-up telephone, or home visits. During the follow-up visit, ICTs identified "what matters," performed geriatric screens aligned with Age-Friendly Health Systems, observed home safety risks, assisted with video telehealth check-ins with ED providers, and provided care coordination. SCOUTS visit data were recorded in the patient's electronic medical record using a standardized template. DATA COLLECTION/EXTRACTION METHODS: Sites were surveyed via electronic form. Administrative pilot data extracted from VA Corporate Data Warehouse, May-October 2021. PRINCIPLE FINDINGS: Site surveys showed none of the EDs had a formalized way of identifying the 4 M "what matters." During the pilot, ICT performed 56 telephone and 247 home visits. All home visits included a telehealth visit with an ED provider (n = 244) or geriatrician (n = 3). ICTs identified 44 modifiable home fall risks and 99 unmet care needs, recommended 80 pieces of medical equipment, placed 36 specialty care consults, and connected 180 patients to a Patient Aligned Care Team member for follow-up. CONCLUSIONS: A post-ED follow-up program in which former military medics perform geriatric screens and care coordination is feasible. Combining telehealth and home visits allows providers to address what matters and unmet care needs.

Care transitions and social needs: A Geriatric Emergency care Applied Research (GEAR) Network scoping review and consensus statement.

OBJECTIVES: Individual-level social needs have been shown to substantially impact emergency department (ED) care transitions of older adults. The Geriatric Emergency care Applied Research (GEAR) Network aimed to identify care transition interventions, particularly addressing social needs, and prioritize future research questions. METHODS: GEAR engaged 49 interdisciplinary stakeholders, derived clinical questions, and conducted searches of electronic databases to identify ED discharge care transition interventions in older adult populations. Informed by the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) framework, data extraction and synthesis of included studies included the degree that intervention components addressed social needs and their association with patient outcomes. GEAR convened a consensus conference to identify topics of highest priority for future care transitions research. RESULTS: Our search identified 248 unique articles addressing care transition interventions in older adult populations. Of these, 17 individual care transition intervention studies were included in the current literature synthesis. Overall, common care transition interventions included coordination efforts, comprehensive geriatric assessments, discharge planning, and telephone or in-person follow-up. Fourteen of the 17 care transition intervention studies in older adults specifically addressed at least one social need within the PRAPARE framework, most commonly related to access to food, medicine, or health care. No care transition intervention addressing social needs in older adult populations consistently reduced subsequent health care utilization or other patient-centered outcomes. GEAR stakeholders identified that determining optimal outcome measures for ED-home transition interventions was the highest priority area for future care transitions research. CONCLUSIONS: ED care transition intervention studies in older adults frequently address at least one social need component and exhibit variation in the degree of success on a wide array of health care utilization outcomes.

Cardiopulmonary Emergencies in Older Adults.

Older adults are susceptible to serious illnesses, including atrial fibrillation, congestive heart failure, pneumonia, and pulmonary embolism. Atrial fibrillation is the most common arrhythmia in this age group and can cause complications such as thromboembolic events and stroke. Congestive heart failure is the most common cause of hospital admission and readmission in the older adult population. Older adults are at higher risk for pulmonary embolism because of age-related changes and comorbidities. Pneumonia is also prevalent and is one of the leading causes of death.

Emergency Department Interventions for Older Adults: A Systematic Review.

OBJECTIVES: To evaluate the effect of emergency department (ED) interventions on clinical, utilization, and care experience outcomes for older adults. DESIGN: A conceptual model informed, protocol-based systematic review. SETTING: Emergency Department (ED). PARTICIPANTS: Older adults 65 years of age and older. METHODS AND MEASUREMENT: Medline, Embase, CINAHL, and PsycINFO were searched for English-language studies published through December 2017. Studies evaluating the use of one or more eligible intervention strategies (discharge planning, case management, medication safety or management, and geriatric EDs including those that cited the 2014 Geriatric ED Guidelines) with adults 65 years of age and older were included. Studies were classified by the number of intervention strategies used (ie, single strategy or multi-strategy) and key intervention components present (ie, assessment, referral plus follow-up, and contact both before and after ED discharge ["bridge"]). The effect of ED interventions on clinical (functional status, quality of life [QOL]), patient experience, and utilization (hospitalization, ED return visit) outcomes was evaluated. RESULTS: A total of 2000 citations were identified; 17 articles describing 15 unique studies (9 randomized and 6 nonrandomized) met eligibility criteria and were included in analyses. ED interventions showed a mixed pattern of effects. Overall, there was a small positive effect of ED interventions on functional status but no effects on QOL, patient experience, hospitalization at or after the initial ED index visit, or ED return visit. CONCLUSION: Studies using two or more intervention strategies may be associated with the greatest effects on clinical and utilization outcomes. More comprehensive interventions, defined as those with all three key intervention components present, may be associated with some positive outcomes.

Optimal older adult emergency care: introducing multidisciplinary geriatric emergency department guidelines from the American College of Emergency Physicians, American Geriatrics Society, Emergency Nurses Association, and Society for Academic Emergency Medicine.

In the United States and around the world, effective, efficient, and reliable strategies to provide emergency care to aging adults is challenging crowded emergency departments (EDs) and a strained health care system. In response, geriatric emergency medicine (EM) clinicians, educators, and researchers collaborated with the American College of Emergency Physicians (ACEP), American Geriatrics Society (AGS), Emergency Nurses Association (ENA), and the Society for Academic Emergency Medicine (SAEM) to develop guidelines intended to improve ED geriatric care by enhancing expertise, educational, and quality improvement expectations; equipment; policies; and protocols. These "Geriatric Emergency Department Guidelines" represent the first formal society-led attempt to characterize the essential attribute of the geriatric ED and received formal approval from the boards of directors for each of the four societies in 2013 and 2014. This article is intended to introduce EM and geriatric health care providers to the guidelines, while providing proposals for educational dissemination, refinement via formal effectiveness evaluations and cost-effectiveness studies, and institutional credentialing.

Randomized clinical trial of an emergency department observation syncope protocol versus routine inpatient admission.

STUDY OBJECTIVE: Older adults are frequently hospitalized from the emergency department (ED) after an episode of unexplained syncope. Current admission patterns are costly, with little evidence of benefit. We hypothesize that an ED observation syncope protocol will reduce resource use without adversely affecting patient-oriented outcomes. METHODS: This randomized trial at 5 EDs compared an ED observation syncope protocol to inpatient admission for intermediate-risk adults (≥50 years) presenting with syncope or near syncope. Primary outcomes included inpatient admission rate and length of stay. Secondary outcomes included 30-day and 6-month serious outcomes after hospital discharge, index and 30-day hospital costs, 30-day quality-of-life scores, and 30-day patient satisfaction. RESULTS: Study staff randomized 124 patients. Observation resulted in a lower inpatient admission rate (15% versus 92%; 95% confidence interval [CI] difference -88% to -66%) and shorter hospital length of stay (29 versus 47 hours; 95% CI difference -28 to -8). Serious outcome rates after hospital discharge were similar for observation versus admission at 30 days (3% versus 0%; 95% CI difference -1% to 8%) and 6 months (8% versus 10%; 95% CI difference -13% to 9%). Index hospital costs in the observation group were $629 (95% CI difference -$1,376 to -$56) lower than in the admission group. There were no differences in 30-day quality-of-life scores or in patient satisfaction. CONCLUSION: An ED observation syncope protocol reduced the primary outcomes of admission rate and hospital length of stay. Analyses of secondary outcomes suggest reduction in index hospital costs, with no difference in safety events, quality of life, or patient satisfaction. Our findings suggest that an ED observation syncope protocol can be replicated and safely reduce resource use.

Overtreatment of presumed urinary tract infection in older women presenting to the emergency department.

OBJECTIVES: To determine how often older women presenting to an emergency department (ED) are diagnosed with a urinary tract infection (UTI) without a positive urine culture and to investigate whether collecting urine by catheterization instead of clean catch improves the accuracy of the urinalysis (UA). DESIGN: Retrospective chart review. SETTING: Academic-affiliated ED in Providence, Rhode Island. PARTICIPANTS: One hundred fifty-three women aged 70 and older with diagnosis of UTI in the ED between December 1, 2008, and March 1, 2010. MEASUREMENTS: Chief complaint, review of systems, results of UA and culture, urine procurement (clean catch, straight catheter, or newly inserted Foley catheter), antibiotic administered or prescribed, and diagnosis. A confirmed UTI was defined as a positive urine culture, with microbial growth of 10,000 colony-forming units (CFU)/ mL or more for clean-catch specimens and 100 CFU/mL or more for newly inserted catheter specimens; an ED diagnosis of UTI was defined as the designation by an ED physician. RESULTS: Of 153 individuals with an ED-diagnosed UTI, only 87 (57%) had confirmed UTI according to culture. Of the remaining 66 with negative cultures, 63 (95%) were administered or prescribed antibiotics in the ED. The method of urine procurement affected the ability of a UA to predict the culture result (P = .02), with catheterization yielding a lower proportion of false-positive UA (31%) than clean catch (48%). CONCLUSION: Nearly half of older women diagnosed with a UTI in an ED setting did not have confirmatory findings on urine culture and were therefore inappropriately treated. Catheterization improved the accuracy of UA when assessing older women for possible UTI.

Health care utilization before and after an outpatient ED visit in older people.

BACKGROUND: Older adults in the United States receive a significant amount of care in the emergency department (ED), yet the associations between ED and other types of health care utilization have not been adequately studied in this population. OBJECTIVES: The goals of this study were to examine the relationships between health care use before and after an ED visit among older adults. METHODS: This retrospective cohort study examined health care use among 308 patients 65 years or older discharged from a university-affiliated ED. Proportional-hazards models were used to assess the relationship between pre-ED health care use (primary care physician [PCP], specialist, ED, and hospital) and risk of return ED visits. RESULTS: Older ED patients in this study had visited other types of providers frequently in the previous year (median number of PCP and specialist visits, 4). Patients who used the ED on 2 or more occasions in the previous year were found to have visited their PCP more often than those without frequent ED use (median number of visits, 7.0 vs 4.0; P < .001). Despite more PCP use in this population, frequent ED use was associated with increased risk of a repeat ED visit (hazard ratio, 2.20; 95% confidence interval, 1.15-4.21), in models adjusted for demographics and health status. CONCLUSION: Older adults who use the ED are also receiving significant amounts of care from other sources; simply providing additional access to care may not improve outcomes for these vulnerable individuals.

Older patients' understanding of emergency department discharge information and its relationship with adverse outcomes.

OBJECTIVES: To describe older patients' understanding of emergency department (ED) discharge information and to explore the relationship between understanding of ED discharge information and adverse outcomes. METHODS: Telephone interviews were conducted with patients 65 years or older (or their proxies) within 72 hours of discharge from an academic medical center ED. We assessed 4 areas of discharge information: ED diagnosis, expected course of illness, self-care instructions, and return precautions. Adverse events were defined as repeat ED visits and hospitalizations or deaths within 90 days of ED discharge. Reverse Kaplan-Meier curves were constructed to illustrate cumulative event probabilities according to patient understanding of discharge information (differences examined with log-rank tests). RESULTS: Of 92 respondents (mean patient age, 75.1; SD, 7.4; 59.8% female subjects), patients or proxies reported not understanding discharge information about diagnosis (20.7%), self-care instructions (16.3%), expected course of illness (63%), and return precautions (55.7%). Within 90 days of ED discharge, 42.3% of patients had returned to the ED, 30.4% were hospitalized, and 4.3% had died. There was little difference in cumulative event probabilities according to whether patients understood self-care instructions or return precautions. Adverse event probabilities were higher among patients who did not understand their ED diagnosis (P = 0.33) and those who did not understand expected course of illness (P = 0.12), although these did not achieve statistical significance. CONCLUSIONS: A substantial number of older patients, or proxies, may not understand ED discharge information, and this could have an effect on patient outcomes. Strategies are needed to improve communication of ED discharge information to older patients and their families.

Acute abdominal pain in the older adult.

Abdominal pain in older adults is a concerning symptom common to a variety of diagnoses with high morbidity and mortality. Organizing the differential into categories based on pathology (inflammatory, obstructive, vascular, or other causes) provides a framework for the history, physical, and diagnostic studies. An organized approach and treatment and considerations specific to the geriatric population are discussed.
