Revascularization in frail patients with acute coronary syndromes: a retrospective longitudinal study.

Frailty is increasingly prevalent in people presenting with acute coronary syndrome (ACS). This high-risk group is typically excluded from trials of interventions in ACS, and there is uncertainty about the risks and benefits of invasive management. Patients with an ACS diagnosis between 2010 and 2015 in England were identified from Hospital Episode Statistics, with linked Office for National Statistics mortality data. Frailty was defined by the Hospital Frailty Risk Score. Causal inference analysis used regional variation in revascularization as an instrumental variable to estimate average treatment effects of revascularization on cardiovascular mortality up to 5 years in people presenting with ACS and low-, intermediate-, or high-risk frailty. The analysis included 565 378 ACS patients, of whom 11.6% (n = 65 522) were at intermediate risk and 4.7% (n = 26 504) were at high risk of frailty. Intermediate and high frailty risks were associated with reduced likelihood of echocardiography, invasive angiography, or revascularization and increased likelihood of mortality and major adverse cardiovascular events compared with low frailty risk. Cardiovascular death at 5 years was 78.6%, 77.3%, and 75.7% in people at low, intermediate, and high frailty risk, respectively. Instrumental variable analysis suggested that revascularization resulted in a higher absolute reduction in cardiovascular mortality in high and intermediate frail risk patients compared with low risk at 1-year post-ACS. Frailty is common in people presenting with ACS, where cardiovascular causes are the principal mode of death. Revascularization is associated with short- and long-term survival benefits in people at intermediate and high risk of frailty after adjustment for measured and unmeasured confounders.

Gabapentinoids and Risk of Hip Fracture.

The increased use of gabapentinoids has been most pronounced in older people who are also susceptible to hip fractures. To investigate the overall association between gabapentinoids and the risk of hip fractures and the stratified association across age groups, frailty status, and history of chronic kidney disease. This was a case-case-time-control study in patients hospitalized for hip fracture in Victoria, Australia, between March 1, 2013, and June 30, 2018, with at least 1 prescription for a gabapentinoid before fracture. Conditional logistic regression was used to estimate the odds ratio (OR) and 95% CI for gabapentinoid dispensing in the index (1-60 days prefracture) compared with the reference (121-180 days prefracture) period. To adjust for the underlying time trend in gabapentinoid use, each index case was matched with up to 5 controls, selected from future cases of the same age and sex. Subgroup analyses were conducted in subgroups with or without chronic kidney disease (CKD), frailty scores less than 5, and frailty scores 5 and above. Frailty was computed using the Hospital Frailty Risk Score (HFRS). Data were analyzed from November 2023 to April 2024. Gabapentinoids (pregabalin or gabapentin). Hip fracture. Of 28 293 patients hospitalized for hip fractures, 2946 (1752 [59.5%] aged ≥80 years; 2099 [71.2%] female) were dispensed a gabapentinoid before hip fracture. Gabapentinoid dispensing was associated with increased odds of hip fractures (OR, 1.96; 95% CI, 1.66-2.32). After adjusting for the exposure-time trend and concomitant use of other central nervous system medications, the odds of hip fractures remained elevated (OR, 1.30; 95% CI, 1.07-1.57). The association between gabapentinoid dispensing and hip fracture was higher in patients with HFRS 5 and above (OR, 1.75; 95% CI, 1.31-2.33) and CKD (OR, 2.41; 95% CI, 1.65-3.52). In this case-case-time-control study of Australian residents hospitalized for hip fracture, gabapentinoid use was associated with an increased risk of hip fractures, especially in patients who were frail or had chronic kidney disease. In addition to the known risk associated with kidney impairment, frailty status may be an important risk factor when considering use of gabapentinoids.

Abstract 4135273: Frailty increases the risk of in-hospital mortality and post-procedural complications in patients undergoing Cardiac Implantable Electronic Devices placement

Background: Heart failure with reduced ejection fraction (HFrEF) often necessitates the use of cardiac implantable electronic devices (CIED) such as cardiac resynchronization therapy defibrillators (CRT-D) or implantable cardioverter-defibrillators (ICD). These devices are proven to reduce mortality, prevent hospitalizations, and improve symptoms and quality of life. Frailty, characterized by an age-associated decline in physiological reserve, significantly impacts outcomes in these patients. This study uses the Hospital Frailty Risk Score (HFRS) to assess the effect of frailty on mortality and post-procedural complications in HFrEF patients undergoing CIED implantation. Hypothesis: Frail patients with HFrEF have worse in-hospital outcomes after CIED placement Methods: We conducted a retrospective cohort study using the 2020 National Inpatient Sample database from the Healthcare Utilization Project. Our population included patients aged 18 years or older with HFrEF who underwent CRT-D or ICD placement, identified using ICD-10 procedure codes. The primary risk factor was frailty, classified by an HFRS score of ≥5 (frail) or <5 (not frail). The primary outcome was in-hospital mortality, and the secondary outcome was the composite of post-procedural complications. Multivariate regression analysis was used to estimate the odds ratio. Results: Out of 24,809 patients who underwent ICD or CRT-D placement, 48.8% were frail. Non-Frail patients had lower mean age compared to Frail patients (66.2 vs 67.3 years old, p=0.003). In-hospital mortality was 1.1%, and 7% experienced post-procedural complications. In-hospital mortality was higher in frail patients compared to non-frail patients (2% vs 0.3%, p<0.001). In the multivariate analysis, frail patients had higher odds of in-hospital mortality compared to the non-frail group subset (OR=5.97; 95% CI: 2.77-12.88, p<0.001). Additionally, frailty was associated with higher odds of post-procedural complications (OR=1.28; 95% CI: 1.01-1.63, p<0.001), increased length of stay (5 vs 11.6 days, p<0.001), and total hospital charges (215,668 vs 324,474 , p<0.001). Conclusion: Frailty significantly increases the risk of in-hospital mortality and post-procedural complications in HFrEF patients. This highlights the importance of considering frailty as part of a pre-procedural risk stratification assessment and tailoring management strategies to improve outcomes for these high-risk patients.

Meta-Analysis: Prevalence of Frailty and Associated Adverse Events in Inflammatory Bowel Diseases.

The number of adults aged over 60 years with inflammatory bowel disease (IBD) is increasing. Frailty, rather than chronological age, may be a better predictor of adverse health outcomes. To summarise current knowledge about frailty in adults with IBD including the prevalence and associations of frailty and IBD-related adverse outcomes. We performed an electronic search of MEDLINE, EMBASE and EMBASE Classic databases using search terms for IBD and frailty from inception to 14 February 2024. All studies involving adults aged ≥ 16 with a confirmed diagnosis of IBD that included a frailty assessment were eligible for inclusion. We included 23 observational studies involving 1,893,448 adults. Risk of bias was low for 18 studies and moderate for five. Twelve methods of frailty assessment were used, the most common being the Hospital Frailty Risk Score. Pooled prevalence of frailty in IBD patients was 18% (95% confidence interval (CI) 12.4%-25.6%). Meta-analysis of unadjusted events data demonstrated that frailty increased the risk of infection-related admissions following treatment in two studies (relative risk (RR) 1.9; 95% CI 1.2-3.0), post-operative morbidity in three (RR 2.0; 95% CI 1.4-2.7) and mortality in seven (RR 4.3; 95% CI 2.6-7.4). Frailty is common in patients with IBD and is associated with IBD-related adverse outcomes including infection-related admissions following treatment, post-operative morbidity and death. Future work should focus on developing risk assessment tools to better support decision making for older people with frailty and IBD.

Prognostic Value of Hospital Frailty Risk Score and Clinical Outcomes in Critical Limb-Threatening Ischemia and End-Stage Kidney Disease.

End-stage kidney disease (ESKD) is commonly associated with critical limb-threatening ischemia (CLTI) and frailty. Yet there are no specific tools to predict outcomes of CLTI in ESKD, particularly those that incorporate frailty. We aimed to assess the utility of the medical record-based Hospital Frailty Risk (HFR) score in predicting outcomes of CLTI in ESKD. We identified patients with ESKD diagnosed with CLTI from the US Renal Data System from 2015 to 2018. These patients were categorized into 3 frailty risk groups on the basis of their HFR scores: low (<5), intermediate (5-10), high-risk (>10), and on the basis of whether they underwent revascularization (endovascular revascularization [ER]/surgical revascularization [SR]) or not (no revascularization). Primary outcomes of interest included in-hospital composite of death or major amputation and in-hospital death. We included 49 454 eligible patients, with ER/SR cohort including 19.8% (n=9777). A total of 88.4% (ER/SR) and 90.0% (no revascularization) were frail on the HFR scale. We found a nonlinear association between HFR score and in-hospital adverse outcomes. In both cohorts, intermediate and high-risk HFR scores were associated with greater risk of in-hospital death (high-risk, ER/SR: odds ratio, 2.7 [95% CI, 1.6-4.8]; P<0.0001; no revascularization: odds ratio, 7.8 [95% CI, 5.3-11.6]; P<0.01) and composite of in-hospital major amputation or death (high-risk, ER/SR: odds ratio, 2.4 [95% CI, 1.9-3.1]; P<0.0001; no revascularization: odds ratio, 1.7 [95% CI, 1.5-1.9]; P<0.0001). The HFR score can predict risk of in-hospital death and composite ofdeath or major amputation in patients with ESKD and CLTI. Further data are needed to determine the utility of the HFR score in this population.

Impact of Frailty on COVID-19 Hospitalizations: Results from the California State Inpatient Database.

Frail patients are at greater risk of experiencing adverse clinical outcomes in any critical illness due to decreased physiologic reserves, greater susceptibility to the adverse effects of treatment, and greater needs for intensive care. In this study, we sought to assess the prevalence of frailty and associated adverse in-hospital outcomes among coronavirus disease 2019 (COVID-19) hospitalizations using the 2020 California State Inpatient Database (SID). For this study, we conducted a retrospective analysis of data from all COVID-19 hospital patients aged 18 years and older. We identified hospitalizations that were at high risk of frailty using the Hospital Frailty Risk Score. The primary outcome of our study was in-hospital mortality, and the secondary outcomes were prolonged length of stay, vasopressor use, mechanical ventilation, and intensive care unit admission. The prevalence of frailty was 44.3% among COVID-19 hospitalizations. Using propensity score matching analysis, we found that the odds of mortality (odds ratio [OR] 4.54, 95% confidence interval [CI] 4.28-4.82), prolonged length of stay (OR 2.81, 95% CI 2.70-2.90), vasopressor use (OR 8.65, 95% CI 7.45-10.03), mechanical ventilation (OR 6.90, 95% CI 6.47-7.35), and intensive care unit admission (OR 7.17, 95% CI 6.71-7.66) were significantly higher among the group of frail patients. Our findings show that frailty could be used for assessing and risk stratifying patients for improved hospital outcomes.

Health care utilization at the end of life in Parkinson’s disease: a population-based register study

BackgroundKnowledge of health care utilization at the end of life in Parkinson’s disease (PD) is sparse. This study aims to investigate end of life health care utilization, characterized by emergency room (ER) visits, receipt of specialized palliative care (SPC), and acute hospital deaths in a Swedish population-based PD cohort.MethodsWe conducted a retrospective cohort study on deceased patients (≥ 18 years) with a PD diagnosis during their last year of life (n = 922), based on health care-provider data from Region Stockholm´s data warehouse, for the study period 2015–2021. Univariable and multivariable logistic regression analyses tested associations and adjusted Odds ratios (aORs) were calculated.ResultsDuring the last month of life, approx. half of the cohort had emergency room (ER) visits and risk of frailty (measured by Hospital Frailty Risk Score) significantly predicted these visits (aOR, 3.90 (2.75–5.55)). In total, 120 people (13%) received SPC during their last three months of life, which positively associated with risk for frailty, (aOR, 2.65 (1.43–4.94, p = 0.002). In total, 284 people (31%) died in acute hospital settings. Among community-dwellers, male gender and frailty were strongly associated with acute hospital deaths (aOR, 1.90 (1.15–3.13, p = 0.01) and 3.70 (1.96–6.98, p < 0.0001)).ConclusionsRates of ER visits at end of life and hospital deaths were relatively high in this population-based cohort. Considering a high disease burden, referral to SPC at end of life was relatively low. Sex-specific disparities in health care utilization are apparent. Identifying people with high risk for frailty could assist the planning of optimal end-of-life care for people with PD.

Temporal trends in mortality and hospitalisation risk in patients with heart failure according to frailty status

Abstract Background Heart failure (HF) and frailty often coexist, and patients with both conditions have a higher risk of mortality and hospitalisation compared with those who are not frail. Over the past two decades, advances in medication targeting HF have been introduced, prolonging the life of patients with HF, but also resulting in increased comorbidity accumulation and susceptibility to frailty. It remains unknown how the interplay between HF and frailty at HF onset impacts patient prognosis and how this has changed over time. Purpose We investigated the temporal trends in the risk of all-cause mortality and HF hospitalisation in patients with HF from 1999 to 2017 according to their frailty status. Methods From Danish nationwide registers, we included patients with new-onset HF. Patients were categorised into four groups according to the year of HF onset: 1999-2002, 2003-2007, 2008-2012, and 2013-2017. The Hospital Frailty Risk Score was used to classify patients into frailty severity categories: 1) non-frail, 2) moderately frail, and 3) severely frail. The primary outcome was the 5-year cumulative incidence of all-cause mortality, assessed using the Kaplan-Meier estimator. The secondary outcome was the 5-year risk of HF hospitalisation, assessed using the Aalen-Johansen estimator, accounting for the competing risk of death. Moreover, a sensitivity analysis was conducted using a multivariable Cox proportional hazard model, investigating the interaction between year group and frailty status for all-cause mortality, comparing frail patients with non-frail patients. Results Among 131,235 patients with HF (median age 74 years; 39.7% female), 102,635 (78%) were categorised as non-frail, 26,054 (20%) as moderately frail, and 2609 (2%) as severely frail. The proportion of moderately frail patients increased the most, from 13% in 1999 to 25% in 2017. From 1999-2002 to 2003-2017, the 5-year cumulative incidence of all-cause mortality declined from 56.4% (95% CI, 55.8-57.0%) to 33.3% (32.6-34.1%), 79.8% (78.5-81.0%) to 58.6% (57.2-60.1%), and 90.8% (85.6-96.0%) to 79.8% (76.4-83.2%) in the non-frail, moderately frail, and severely frail patient group, respectively (Fig 1). The largest relative improvement was observed in the non-frail patient group. The 5-year cumulative incidence of HF hospitalisation remained fairly constant across the frailty groups (Fig 2). Conclusions From 1999 to 2017, we observed an increase in moderately and severely frail patients. Overall, the mortality risk decreased across all frailty groups. These findings underscore the importance of implementing guidelines directed at frail patients with HF.5-year risk of all-cause mortality5-year risk of HF hospitalisation

Switching from warfarin to a DOAC in frail elderly asian patients with atrial fibrillation: a nationwide population-based study

Abstract Background Recently, switching international normalized ratio guided warfarin management to a direct oral anticoagulant (DOAC) was associated with more bleeding complications than maintaining warfarin in frail elderly patients with atrial fibrillation (AF). However, there is a paucity of information on whether these results could be applied to Asian patients with AF, who are known to have relatively low time in therapeutic range (TTR) levels. Purpose To evaluate the safety and effectiveness of switching from warfarin to a DOAC in frail elderly Asian patients with AF. Methods Using a Korean health insurance database, we included patients with AF who were prescribed warfarin between January 2013 and August 2015 without significant bleeding or thromboembolic events during the window period, specifically those aged 75 or older with a Hospital Frailty Risk Score of 5 or more. Those who switched to DOACs during the window period were categorized as the DOAC group and those who continued with warfarin were categorized as the warfarin group. The primary outcome was defined as the composite of major bleeding (MB) and clinically relevant non-major bleeding (CRNMB), and secondary outcomes were defined as thromboembolic events, all-cause death, the composite of MB, CRNMB and ischemic stroke (so-called net clinical outcome [NCO]). The propensity score weighting method was utilized to compare the two groups. Results A total of 12,162 patients were included (8,108 with maintaining warfarin, 4,054 with switching to a DOAC). Baseline characteristics were well-balanced after the inverse probability of treatment weighting (mean age, 80 years; men, 50%; and mean CHA₂DS₂-VASc score, 5.6). Compared with maintaining warfarin, switching to a DOAC was associated with significantly higher risks of the primary outcome (hazard ratio [HR] 1.43, 95% confidence interval [CI] 1.09-1.87, p=0.01), thromboembolic events (1.28, 1.01-1.62, p=0.039), all-cause death (1.38, 1.15-1.66, p&amp;lt;0.001) and the NCO (1.26, 1.01-1.58, p=0.04). (Figure A, Figure B), whereas there was no difference in the risk of intracerebral hemorrhage (0.90, 0.50-1.60, p=0.7157). When comparing each DOAC with maintaining warfarin, switching to rivaroxaban was associated with a higher risk of the composite of MB and CRNMB (1.91, 1.38-2.64, p&amp;lt;0.001) and thromboembolic events (1.40, 1.03-1.91, p=0.034) than maintaining warfarin. Conclusion In line with the non-Asian population, switching to a DOAC was associated with a significantly higher risk of MB or CRNMB, thromboembolic events, all-cause death and NCO compared with maintaining warfarin in frail elderly Asian patients with AF. Therefore, even in Asians, switching to a DOAC should be considered more cautiously in patients who are stably managed on warfarin.

Relative effectiveness of high-dose versus standard-dose quadrivalent influenza vaccine against hospitalizations and mortality according to frailty score: a post-hoc analysis of the DANFLU-1 trial

Abstract Background Frailty is a major risk factor for adverse cardiovascular events. Influenza vaccination has been shown to protect against cardiovascular fatal and nonfatal events. However, limited data exist on the added benefit of high-dose versus standard-dose influenza vaccination according to frailty status. Purpose We sought to assess the relative effectiveness of high-dose (QIV-HD) versus standard-dose (QIV-SD) quadrivalent influenza vaccination according to frailty status in elderly individuals. Methods This is a post-hoc analysis of the randomized controlled feasibility trial of QIV-HD versus QIV-SD conducted during the 2021–2022 influenza season in adults aged 65–79 years. We assessed the following prespecified outcomes: hospitalizations for pneumonia or influenza, cardio-respiratory hospitalizations, cardiovascular hospitalizations, all-cause hospitalizations and all-cause mortality. Level of frailty was defined according to the Hospital Frailty Risk Score based on ICD-10 codes for relevant comorbidities any time prior to vaccination. We divided the participants into two categories according to Frailty Score (FS): low frailty (0-4 points) and intermediate or high frailty (≥5 points). We analyzed outcomes as time to first event using Cox proportional hazards regression. Results Among 12,473 randomly assigned participants to QIV-HD versus QIV-SD (mean age 71.7 years, 47.1% female), 10,711 (85.9%) were categorized as having low frailty and 1,762 (14.1%) had intermediate or high frailty. In total, 38 individuals were hospitalized for pneumonia or influenza during follow-up, 219 were hospitalized for cardiorespiratory illness, 1055 were hospitalized due to any cause and 62 died during follow-up. FS significantly modified the effect of QIV-HD versus QIV-SD for all-cause mortality (P for interaction 0.02). In participants with low frailty, QIV-HD was associated with a lower risk of all-cause mortality (Figure 1: HR 0.26, 95% CI 0.13 to 0.55), whereas there was no evidence of effect among those with intermediate or high frailty (HR 1.68, 95% CI 0.66 to 4.26). QIV-HD versus QIV-SD was associated with a lower incidence of hospitalizations for pneumonia and influenza, this effect was consistent regardless of frailty status (P for interaction 0.88). QIV-HD was not associated with a significantly lower incidence of hospitalizations due to cardiovascular, cardiorespiratory or respiratory disease or any cause regardless of frailty status. Conclusions In this post-hoc analysis of a large-scale pragmatic trial, QIV-HD was similarly associated with a lower incidence of hospitalizations for pneumonia and influenza among older adults irrespective of frailty status. The potential benefit of QIV-HD versus QIV-SD may therefore be applicable regardless of frailty status. However, our results suggest that QIV-HD is associated with a lower risk of all-cause mortality among adults with low frailty only.Figure 1.

Impact of Frailty on Early Readmissions of Endoscopic Retrograde Cholangiopancreatography in the United States: Where Do We Stand?

Background/Objectives: We assessed the impact of frailty on outcomes of endoscopic retrograde cholangiopancreatography (ERCP) in the United States. Methods: The National Readmission Database (2016-2020) was used to identify index and 30-day ERCP readmissions, which were categorized into low-frailty, intermediate-frailty, and high-frailty groups based on the Hospital Frailty Risk Score (HFRS). Outcomes were then compared. Results: Of 885,416 index admissions, 9.9% were readmitted within 30 days of ERCP. The odds of 30-day readmission were higher in the intermediate-frailty group (12.59% vs. 8.2%, odds ratio [OR] 1.67, 95% confidence interval [CI] 1.64-1.71, p < 0.001) and the high-frailty group (10.57% vs. 8.2%, OR 1.62, 95% CI 1.52-1.73, p < 0.001) compared to the low-frailty group. On readmission, a higher HFRS also increased mean length of stay (intermediate-frailty vs. low-frailty: 8.49 vs. 4.22 days, mean difference (MD) 4.26, 95% CI 4.19-4.34, p < 0.001; high-frailty vs. low-frailty: 10.9 vs. 4.22 days, MD 10.9 days, 95% CI 10.52-11.28, p < 0.001) and mean total hospitalization charges (intermediate-frailty vs. low-frailty: $118,996 vs. $68,034, MD $50,962, 95% CI 48, 854-53,069, p < 0.001; high-frailty vs. low-frailty: $195,584 vs. $68,034, MD $127,550, 95% CI 120,581-134,519, p < 0.001). The odds of inpatient mortality were also higher for the intermediate-frailty and high-frailty compared to the low-frailty subgroup. Conclusions: Frailty was associated with worse clinical outcomes after ERCP.

Predicting frailty domain impairments and mortality with the Hospital Frailty Risk Score among older adults with cancer: the ELCAPA-EDS cohort study.

Automated frailty screening tools like the Hospital Frailty Risk Score (HFRS) are primarily validated for care consumption outcomes. We assessed the predictive ability of the HFRS regarding care consumption outcomes, frailty domain impairments and mortality among older adults with cancer, using the Geriatric 8 (G8) screening tool as a clinical benchmark. This retrospective, linkage-based study included patients aged ≥70years with solid tumor, enrolled in the Elderly Cancer Patients (ELCAPA) multicentre cohort study (2016-2020) and hospitalized in acute care within the Greater Paris University Hospitals. HFRS scores, which encompass hospital-acquired problems and frailty-related syndromes, were calculated using data from the index admission and the preceding 6months. A multidomain geriatric assessment (GA), including cognition, nutrition, mood, functional status, mobility, comorbidities, polypharmacy, incontinence, and social environment, was conducted at ELCAPA inclusion, with computation of the G8 score. Logistic and Cox regressions measured associations between the G8, HFRS, altered GA domains, length of stay exceeding 10days, 30-day readmission, and mortality. Among 587 patients included (median age 82years, metastatic cancer 47.0%), 237 (40.4%) were at increased frailty risk by the HFRS (HFRS>5) and 261 (47.5%) by the G8 (G8≤10). Both HFRS and G8 were significantly associated with cognitive and functional impairments, incontinence, comorbidities, prolonged length of stay, and 30-day mortality. The G8 was associated with polypharmacy, nutritional and mood impairment. Although showing significant associations with short-term care consumption, the HFRS could not identify polypharmacy, nutritional, mood and social environment impairments and showed low discriminatory ability across all GA domains.

Impact of the Hospital Frailty Risk Score on Outcomes following Primary Total Elbow Arthroplasty

The Hospital Frailty Risk Score (HFRS) has demonstrated strong correlation with adverse outcomes in various joint replacement surgeries, yet its applicability in total elbow arthroplasty (TEA) remains unexplored. The purpose of this study is to assess the association between HFRS and postoperative complications following elective primary TEA. The Nationwide Readmissions Database was queried to identify patients undergoing primary TEA from 2016 to 2020. The HFRS was used to compare medical, surgical, and clinical outcomes of frail vs. non-frail patients. Mean and relative costs, total hospital length of stay (LOS), and discharge disposition for frail and non-frail patients were also compared. We identified 2,049 primary TEA in frail patients and 3,693 in non-frail patients. Frail patients had increased complication rates including acute respiratory failure (13.6% vs. 1.1%; p < 0.001), urinary tract infections (12.3% vs. 0.0%; p < 0.001), transfusions (3.9% vs. 1.1%; p < 0.001), pneumonia (1.1% vs. 0.2%; p < 0.001), acute respiratory distress syndrome (3.2% vs 0.6%; p < 0.001), sepsis (0.7% vs. 0.1%; p < 0.001), and hardware failure (1.2% vs 0.1%; p < 0.001). Frail patients also experienced higher rates of readmission (37% vs. 25%; p < 0.001) and death (1.7% vs. 0.2%; p < 0.001), while being less likely to undergo revision (6.5% vs. 17%; p < 0.001). Frail patients incurred higher healthcare costs ($28,497 vs. $23,377; p < 0.001) and longer LOS (5.3 days vs. 2.6 days; p < 0.001), with reduced likelihood of routine hospital stays (36% vs. 71%; p < 0.001) and increased utilization of short-term hospitalization (p < 0.001), care facilities (p < 0.001), and home health care services (p < 0.001). HFRS is a validated indicator of frailty and is strongly associated with increased rates of complications in patients undergoing elective primary TEA. These findings should be considered by orthopedic surgeons when assessing surgical candidacy and discussing treatment options in this at-risk patient population.

Effect of frailty on unplanned readmission in older adults: A systematic review

BackgroundFrailty and hospital readmissions are two major problems for older people because of their impact on health, quality of life and healthcare systems. The aims of this study were to investigate the relationship between frailty and unplanned readmissions at 30, 90, 180 days and 1 year in hospitalised older people, and to identify the most relevant tools for assessing readmission risk in different clinical settings to facilitate systematic identification of this high-risk population by healthcare professionals. MethodThis review was based on a systematic search of the MEDLINE, EMBASE and SCIENCEDIRECT databases for articles published between January 2011 and December 2021 that examined the association between frailty and unplanned readmission in hospitalised adults aged 65 years and over using identified validated tools. Results44 eligible studies out of 1362 were included in a descriptive analysis. Sixteen countries were represented with older adults hospitalised in medical, surgical, post-acute care and rehabilitation, and emergency departments. Up to 84.5% of frail older adults had an unplanned readmission. Of the 21 tools identified, the Hospital Frailty Risk Score (HFRS), the Frailty Index (FI), its derivatives, the Clinical Frailty Scale (CFS) and the Fried model were the most widely used and relevant tools for identifying the association between frailty and unplanned readmission. ConclusionFrailty is widely associated with readmission risk in older adults. The HFRS, FI, CFS and Fried model appear to be the most commonly used tools to assess frailty and prevent unplanned readmissions.

High hospitalization rates and risk factors among frail patients with cirrhosis: A 10-year population-based cohort study

Cirrhosis-related inpatient hospitalizations have increased dramatically over the past decade. We used a longitudinal dataset capturing a large metropolitan area in the US from 2011-2021 to evaluate contemporary hospitalization rates and risk factors among frail patients with cirrhosis. We conducted a retrospective, longitudinal cohort study using the Chicago Area Patient-Centered Outcomes Research Network (CAPriCORN) database, an electronic health record (EHR) repository that aggregates de-duplicated data across seven healthcare systems in the Chicago metropolitan area, from 2011-2021. The primary outcome of our study was the rate of hospitalization encounters. Frailty was defined by the Hospital Frailty Risk Score. Hospitalization rates were reported per 100 patients per year and a multivariable logistic regression analysis identified predictors of annual hospitalization probability. During the study period, of 36,971 patients, 16,265 patients (44%) were hospitalized (compensated: 18.4%, decompensated: 81.6%). Hospitalization rates were highest in patients with decompensated cirrhosis, reaching nearly 77.3 hospitalizations/100 patients per year. Hospitalization rates among patients with compensated cirrhosis were also high (14.2 vs. 77.3 hospitalization/100 patients per year), with odds of annual hospitalization three times (OR 3.1; 95%CI 2.9-3.4) as high among compensated patients with intermediate frailty and five times (OR 5.2; 95%CI 4.5-6.0) as high among those with severe frailty (compared to compensated patients with low frailty). Compensated and decompensated cirrhosis patients with intermediate to severe frailty face a substantially increased odds of annual hospitalizations compared to those with low frailty. Future work should focus on targeted interventions to incorporate routine frailty screenings into cirrhosis care and to ultimately minimize high hospitalization rates.

Predictors of Morbidity, Mortality, and Hospital Utilization Among Endoscopic Retrograde Cholangiopancreatography-related Hospitalizations: A Five-year Nationwide Assessment.

We aimed to assess the hospital frailty risk score on the inpatient mortality, morbidity, and health care resource utilization among endoscopic retrograde cholangiopancreatography (ERCP)-related hospitalizations. Data regarding the inpatient mortality, morbidity, and health care resource utilization of ERCP among frail individuals remain limited. Using the Nationwide Inpatient Sample, we compared the odds of inpatient mortality and morbidity of ERCP-related hospitalizations among individuals with low frailty scores, intermediate frailty scores (IFSs), and high frailty scores (HFSs). Overall, 776,025 ERCP-related hospitalizations were recorded from 2016 to 2020. 552,045 had a low frailty score, whereas 217,875 had an IFS, and 6105 had an HFS. Frail individuals had a 5-fold increase in mortality [IFS: adjusted odds ratio (aOR) = 4.81, 95% CI: 3.77-6.14; HFS: aOR = 4.62, 95% CI: 2.48-8.63]. An IFS was associated with a 24% increase in post-ERCP pancreatitis (aOR = 1.25, 95% CI: 1.11-1.41), a 3-fold increase in post-ERCP bleeding (aOR = 2.59, 95% CI: 1.82-3.67), and a 2-fold increase in post-ERCP duct perforation (aOR = 1.91, 95% CI: 1.38-2.64). Frail individuals experienced higher odds of in-hospital morbidity, including secondary sepsis, respiratory failure, acute kidney injury, cerebrovascular accidents, deep vein thrombosis, and pulmonary embolism. In summary, our study presents strong evidence in support of using the hospital frailty risk score as an index to predict mortality and morbidity during ERCP-related hospitalizations. Additional caution is warranted in the management of frail individuals undergoing ERCP.

Frailty among stroke patients and its effects on hospital outcomes

BackgroundAlthough assessment of frailty is increasingly being included in routine practice, its effects on hospital outcomes is not well studied. In this study, we used a national database to estimate the effects of frailty on hospital outcomes among stroke patients. MethodsThis study was a retrospective analysis of data from Nationwide Inpatient Sample (NIS) database collected during the years 2016 to 2019. Adult patients 45 years and older with a primary diagnosis of stroke were included for the analysis. Primary outcome was frequency of frailty among stroke patients. Secondary outcomes were in-hospital mortality, prolonged length of stay, mechanical ventilation, and acute renal failure. Frailty levels were assessed by using the Hospital Frailty Risk Score (HFRS). ResultsAmong 2,031,085 stroke hospitalizations, 362,140 (17.8 %) were non-frail, 1,333,000 (65.6 %) were pre-frail, and 335,945 (16.6 %) were frail. Regression analysis showed that the odds of mortality were significantly higher among frail (aOR, 2.82, 95 % CI: 2.63–3.04) and pre-frail (aOR, 1.62, 95 % CI: 1.53–1.73) patients, compared to non-frail patients. Similarly, the odds of mechanical ventilation were significantly higher among frail (aOR, 9.72, 95 % CI: 8.84–10.69) and pre-frail (aOR, 3.41, 95 % CI: 3.12–3.73) patients. The odds of acute renal failure were significantly higher among frail (aOR, 6.96, 95 % CI: 6.62–7.33) and pre-frail (aOR, 2.94, 95 % CI: 2.80–3.08) patients. ConclusionCollaborative efforts by neurologists, neurosurgeons, and physiatrists towards identifying frailty and incorporating it in risk estimation measures could help improve management strategies, resource utilization, and optimization of patient outcomes among frail stroke patients.

Impact of the Hospital Frailty Risk Score on Outcomes After Transcatheter Aortic Valve Replacement in Late Elderly Patients.

Prognostic prediction using objective indices is needed to optimize the indications for transcatheter aortic valve replacement (TAVR). We evaluated the impact of the Hospital Frailty Risk Score (HFRS), an International Classification of Diseases (ICD)-based frailty index, on the prognosis after TAVR in the late elderly. We identified patients aged ≥75 years undergoing TAVR from April 2014 to September 2020 from the Shizuoka Kokuho Database (SKDB). Cox logistic regression analysis was performed to examine predictors of long-term mortality. We also evaluated the relationship between HFRS categories (low risk: <5, intermediate risk: 5-15, high risk: >15) and functional decline. This study involved 607 patients (189 (31.1%) men) with a mean age of 85.0 years. During the median follow-up period of 20 months, survival significantly differed among HFRS categories (survival at two years; low (HFRS <5): 88.9%, intermediate (HFRS 5-15): 82.6%, high (HFRS >15): 67.7%; log-rank p = 0.002). In the multivariate regression model, male sex (hazard ratio (HR): 2.15, 95% confidence interval (CI): 1.42-3.24), preoperative care needs level of ≥3 (HR: 2.43, 95% CI: 1.17-5.06), and HFRS (HR: 1.07, 95% CI: 1.03-1.12) were significant predictors of mortality. Functional decline-free survival significantly differed among HFRS categories (event-free survival at two years; low: 79.4%, intermediate: 75.2%, high: 50.8%; log-rank p = 0.001). The HFRS is a predictor of long-term mortality after TAVR in the late elderly and is associated with postoperative functional decline. The HFRS can provide additional information for decision-making regarding treatment strategies for the late elderly.
