Effectiveness of the frailty index in predicting recurrent pneumonia and death in long-term hospitalized patients with vascular cognitive impairment. Exp Gerontol 2024; 196:112576. [PMID: 39241990 DOI: 10.1016/j.exger.2024.112576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2024] [Revised: 08/31/2024] [Accepted: 09/03/2024] [Indexed: 09/09/2024]
Abstract
OBJECTIVE The aim was to predict the effectiveness of using frailty, defined by the frailty index (FI), for predicting recurrent pneumonia and death in patients 50 years and older with vascular cognitive impairment (VCI) during long-term hospitalization. MEASUREMENTS This retrospective cohort study was conducted at a teaching hospital in western China and included VCI patients aged ≥50 years undergoing long-term hospitalization. The relevant data were collected from the electronic medical record system. The FI was based on 31 parameters and groups were defined using a cutoff value (0.2) as robust (FI < 0.2) and FRAIL (≥0.2). The definition of recurrent pneumonia was a minimum of two episodes within a year, with the symptoms, signs, and imaging results of pneumonia disappearing completely between episodes, and a minimum interval between episodes of seven days. Death was recorded by the hospital as the result of cardiac and respiratory arrest and survival was defined as the interval between hospital admission and confirmed death. Logistic regression models were used to assess the association between FI and recurrent pneumonia, while associations between FI and death were assessed by Cox proportional hazards models. RESULTS A total of 252 long-term hospitalized VCI patients ≥50 years old were enrolled, of whom 115 were male (45.6 %). Ninety-seven patients (38.5 %) were defined as FRAIL. The median length of stay for hospitalized patients was 37 months. Overall, 215 patients developed pneumonia during hospitalization, which occurred an average of 14.5 months after admission, while 151 (59.9 %) had recurrent pneumonia, and 155 (61.5 %) died. Of these, 143 died in the hospital and 12 died after discharge. No significant differences were seen in the incidence of recurrent pneumonia between FRAIL and robust long-term hospitalized VCI patients (FRAIL vs. robust: 66.0 % vs. 56.1 %, P = 0.121) while FRAIL patients had a higher mortality rate than robust patients (FRAIL vs. robust: 71.1 % vs. 55.5 %, P = 0.013). After further Cox regression analysis and adjustment for possible confounders found to be significant in the univariate analysis (including age, sex, smoking history, and activities of daily living (ADL) score), FRAIL patients had a higher risk of death than healthy patients (HR = 1.595, 95 % CI: 1.149-2.213). In addition, based on Model 2, confounding variables that were not statistically significant in the univariate analysis but may have had an impact on the results (including marital status, educational level, drinking history, comorbidity and rehabilitation treatment) were incorporated into Model 3 for further correction. The result remained unchanged, namely, that compared with robust patients, FRAIL patients had a higher risk of death (HR = 1.771, 95 % CI: 1.228-2.554). CONCLUSIONS AND IMPLICATIONS Frailty defined by the FI was effective for predicting the risk of mortality but not that of recurrent pneumonia in long-term hospitalized VCI patients aged 50 or older.

Shah SK, Xiang L, Adler RR, Clark CJ, Hsu J, Mitchell SL, Finlayson E, Kim DH, Lin KJ, Weissman JS. Patients with dementia or frailty undergoing major limb amputation have poor outcomes. J Vasc Surg 2024:S0741-5214(24)01818-4. [PMID: 39226934 DOI: 10.1016/j.jvs.2024.08.058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 08/13/2024] [Accepted: 08/26/2024] [Indexed: 09/05/2024]
Abstract
OBJECTIVE Major lower limb amputation is a disfiguring operation associated with impaired mobility and high near-term mortality. Informed decision-making regarding amputation requires outcomes data. Despite the co-occurrence of both chronic limb-threatening ischemia (CLTI) and Alzheimer's disease and related dementias (ADRD), there is sparse data on the outcomes of major limb amputation in this population and the impact of frailty. We sought to determine mortality, complications, readmissions, revisions, intensive interventions (eg, cardiopulmonary resuscitation), and other outcomes after amputation for CLTI in patients living with ADRD looking at the modifying effects of frailty. METHODS We examined Medicare fee-for-service claims data from January 1, 2016, to December 31, 2020. Patients with CLTI undergoing amputation at or proximal to the ankle were included. Along with demographic information, dementia status, and comorbid conditions, we measured frailty using a claims-based frailty index. We dichotomized dementia and frailty (pre-frail/robust = "non-frail" vs moderate/severe frailty = "frail") to create four groups: non-frail/non-ADRD, frail/non-ADRD, non-frail/ADRD, and frail/ADRD. We used linear and logistic regression via generalized estimating equations in addition to performing selected outcomes analyses with death as a competing risk to understand the association between dementia status, frailty status, and 1-year mortality as our primary outcome in addition to the postoperative outcomes outlined above. RESULTS Among 46,930 patients undergoing major limb amputation, 11,465 (24.4%) had ADRD and 24,790 (52.8%) had frailty. Overall, 55.9% of amputations were below-knee. Selected outcomes among frail/ADRD patients undergoing amputation (n = 10,153) were: 55.3% 1-year mortality 29.6% readmissions at 30 days, and 32.3% amputation revision/reoperation within 1 year. Of all four groups, those in the frail/ADRD had the worst outcomes only for 1-year mortality. CONCLUSIONS First, patients with ADRD or moderate/severe frailty suffer an array of very poor outcomes after major limb amputation for CLTI, including high mortality, readmissions, revision, and risks of discharge to higher levels of care. Second, there is a complex relationship between outcome severity and ADRD/frailty status. Specifically, frailty is more often than ADRD associated with the poorest results for any given outcome. These data provide important outcomes data to help align decision-making with health care values and goals.

Ann Vasc Surg 2024; 109:291-296. [PMID: 39069122 DOI: 10.1016/j.avsg.2024.07.087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Revised: 07/03/2024] [Accepted: 07/09/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Major lower extremity amputation is a significant life-changing event that can have long-term implications. The goal of this study was to assess long-term medical outcomes and social determinants of health (SDH) challenges in this population. METHODS A retrospective review of major lower extremity (previously mentioned ankle) amputations (2018-2022) was performed at a safety-net tertiary care center. Patients who participated in an SDH survey between 6 months and 1.5 years postoperatively were included for survey analysis. Patient demographics, comorbidities, and perioperative and long-term outcomes were analyzed. RESULTS There were 100 patients included. Mean age was 61.5 years and 23% were of female gender. The majority (57%) were Black race, 20% White race, and 21% Hispanic ethnicity. Comorbidities included diabetes (78%), chronic kidney disease (51%), coronary artery disease (31%), congestive heart failure (23%), previous cerebrovascular events (19%), and 37% used opioids preadmission. At baseline, the majority (62%) lived at home. Guillotine amputation was performed in 24%, with definitive amputation in the following and previously mentioned knee in 67% and 33%, respectively. Median length of stay was 7 days. Readmission at 30 days, 90 days, and 1 year was 13%, 30%, and 43% respectively. The average follow up was 839 days. At long-term follow up, 55% lived at home, 25% used opioids, and only 25% were independently ambulatory. In the SDH survey at follow up, 32% identified at least one SDH challenge, with younger patients more often affected (58 vs. 63 years, P = 0.031). SDH challenges consisted of food insecurity (17%), housing insecurity (13%), transportation challenges (13%), seeking employment (8%), difficulty paying for utilities (5%) and medications (4%), seeking further education (5%), and difficulty caring for family/friends (4%). On multivariable analysis, having at least one SDH challenge was independently associated with 1-year readmission (odds ratio 6.7, 95% confidence interval 1.3-35.8, P < 0.001). Older age was associated with lower long-term independent ambulation (odds ratio 0.92, 95% confidence interval 0.85-0.99, P = 0.025). CONCLUSIONS After major lower extremity amputation, patients have significant medical and social challenges with fewer living at home, the majority were not independently ambulatory, and one-third having at least one SDH challenge. Improvements in long-term support including medical, social, and rehabilitation services are required for this vulnerable population.

Abstract
BACKGROUND AND AIMS Frailty is widespread in the elderly, while there is a bi-directional relationship between frailty and malnutrition. The objectives of this study were to investigate the prevalence and correlation of frailty and nutritional risk in older adult patients and to analyse the factors associated with fatigue which is one indicator of frailty. METHODS This cross-sectional multicentre survey study was conducted in five hospitals in the same city from 01 January 2021 to 01 December 2021. We collected information on gender, age, diseases, medication and dietary status. Frailty status was diagnosed using the FRAIL scale, and Nutritional Risk Screening-2002 was used to screen the nutritional risk. Spearman rank correlation was used to analyse the correlation between frailty and nutritional risk. Univariate and multivariate logistic regression analyses were used to analyse the risk factors related to fatigue in all patients and inpatients. RESULTS Among 2016 older adult patients, the prevalence of frailty was 15.1% (305/2016), the prevalence of nutritional risk was 16.2% (327/2016) and the overlap prevalence of frailty and nutritional risk was 7.3% (147/2016). Multivariate analysis showed that nutritional risk (OR 3.109, 95% CI 2.384 to 4.056, p<0.001) was an independent risk factor for fatigue in all patients; similar results were found for nutritional risk (OR 2.717, 95% CI 2.068 to 3.571, p<0.001) in hospitalised patients. CONCLUSIONS Frailty and nutritional risk are prevalent among older adult patients, and nutritional risk is associated with the occurrence of fatigue in older adult patients and older adult inpatients.

Abstract
Increasing evidence highlights the adverse impact of frailty and reduced physiologic reserve on surgical outcomes. Therefore, identification of frailty is essential for older adults being evaluated for vascular surgery procedures. Numerous frailty assessment tools are available to quantify the level of frailty and assist in preoperative decision making for these older patients. This review evaluates traditional and novel frailty metrics for their scientific validation, limitations, and clinical utility in vascular surgery decision-making.

Abstract
BACKGROUND The purpose of this study was to investigate the predictive value of the 5-factor modified frailty index (mFI-5) for postoperative mortality, delirium and pneumonia in patients over 65 years of age undergoing elective lung cancer surgery. METHODS Data were collected from a single-center retrospective cohort study conducted in a general tertiary hospital from January 2017 to August 2019. In total, the study included 1372 elderly patients aged over 65 who underwent elective lung cancer surgery. They were divided into frail group (mFI-5, 2-5), prefrail group (mFI-5, 1) and robust group (mFI-5, 0) on the basis of mFI-5 classification. The primary outcome was postoperative 1-year all-cause mortality. Secondary outcomes were postoperative pneumonia and postoperative delirium. RESULTS Frailty group had the highest incidence of postoperative delirium (frailty 31.2% versus prefrailty 1.6% versus robust 1.5%, p < 0.001), postoperative pneumonia (frailty 23.5% versus prefrailty 7.2% versus robust 7.7%, p < 0.001), and postoperative 1-year mortality (frailty 7.0% versus prefrailty 2.2% versus robust 1.9%. p < 0.001). Frail patients have significantly longer length of hospitalization than those in the robust group and prefrail patients (p < 0.001). Multivariate analysis showed a clear link between frailty and increased risk of postoperative delirium (aOR 2.775, 95% CI 1.776-5.417, p < 0.001), postoperative pneumonia (aOR 3.291, 95% CI 2.169-4.993, p < 0.001) and postoperative 1-year mortality (aOR 3.364, 95% CI, 1.516-7.464, p = 0.003). CONCLUSIONS mFI-5 has potential clinical utility in predicting postoperative death, delirium and pneumonia incidence in elderly patients undergoing radical lung cancer surgery. Frailty screening of patients (mFI-5) may provide benefits in risk stratification, targeted intervention efforts, and assist physicians in clinical decision-making.

Abstract
Frailty, as an age-related syndrome of reduced physiological reserve, contributes significantly to post-operative outcomes. With the aging population, frailty poses a significant threat to patients and health systems. Since 2012, preoperative frailty assessment has been recommended, yet its implementation has been inhibited by the vast number of frailty tests and lack of consensus. Since the anesthesiologist is the best placed for perioperative care, an anesthesia-tailored preoperative frailty test must be simple, quick, universally applicable to all surgeries, accurate, and ideally available in an app or online form. This systematic review attempted to rank frailty tests by predictive accuracy using the c-statistic in the outcomes of extended length of stay, 3-month post-operative complications, and 3-month mortality, as well as feasibility outcomes including time to completion, equipment and training requirements, cost, and database compatibility. Presenting findings of all frailty tests as a future reference for anesthesiologists, Clinical Frailty Scale was found to have the best combination of accuracy and feasibility for mortality with speed of completion and phone app availability; Edmonton Frailty Scale had the best accuracy for post-operative complications with opportunity for self-reporting. Finally, extended length of stay had too little data for recommendation of a frailty test. This review also demonstrated the need for changing research emphasis from odds ratios to metrics that measure the accuracy of a test itself, such as the c-statistic.

Abstract
Introduction Frailty is associated with adverse postoperative health outcomes, including increased mortality, longer length of stay, higher rehospitalization, and other complications. There are many frailty assessment tools are to assess the level of frailty in vascular surgery patients. The aim of this study was to perform a systematic review and meta-analysis to assess the association between the frailty levels described by different frailty scores and adverse postoperative health outcomes among hospitalized vascular surgery patients and patients undergoing amputation. Methods Studies utilizing frailty scores and similar frailty assessment tools to describe frailty and investigate the association between frailty and health outcomes were searched. The primary outcomes of this study were in-hospital mortality, postdischarge mortality, length of hospital stay, rehospitalization, and discharge location. Additional outcomes included postoperative myocardial infarction, postoperative renal failure, cerebrovascular accident and stroke, comorbidities, and estimated glomerular filtration rate (eGFR) levels. Joanna Briggs Institute (JBI) Critical Appraisal Tools were used for quality assessment. Results In total, 24 studies with 1,886,611 participants were included in the final analysis. The overall results found that higher in-hospital mortality and postdischarge mortality were significantly associated with frailty. Frailty was also found to be significantly associated with a longer length of hospital stay, higher rehospitalization, and higher likelihood of non-home discharge. In addition, the results also showed that frailty was significantly associated with all kinds of comorbidities investigated, except chronic kidney disease. However, lower eGFR levels were significantly associated with frailty. Conclusion Among patients who underwent all types of vascular surgery and those who underwent amputations, assessment of frailty was significantly associated with adverse postoperative outcomes and multiple comorbidities.

Abstract
BACKGROUND Multiple frailty screening tools are implemented; however, it is unclear whether they perform in a comparable way for both frailty detection and prediction of perioperative outcomes in patients undergoing lower-extremity revascularization. METHODS Patients undergoing lower-extremity revascularization were identified from the Vascular Quality Initiative (VQI) national database. Two cohorts were established based on the revascularization type (percutaneous vascular interventions (PVI) or lower-extremity bypass). Frailty was assessed by the 5-item modified frailty index (mFI-5) and the VQI-derived risk analysis index (RAI). RESULTS Out of 134,081 patients undergoing PVI, frailty was identified in 67% by mFI-5 and 28% by RAI. Similarly, out of 41,316 patients in the bypass cohort, frailty was identified in 69% by mFI-5 and 16% by RAI. There was little agreement between the two frailty tools for both vascular cohorts (PVI: kappa: 0.17; bypass: kappa: 0.13). In an adjusted analysis, frailty as assessed by mFI-5 and RAI was associated with higher odds of mortality in both cohorts (p < 0.001). A significant association between frailty and unplanned amputations was only noted in the bypass cohort when RAI was applied (OR: 1.50, p < 0.01). The addition of frailty to traditional PAD risk factors marginally improved model performance to predict mortality and unplanned major amputations. CONCLUSION There was significant variation in frailty detection by mFI-5 and RAI. Although frailty was associated with mortality, the predictive value of these tools in predicting outcomes in PAD was limited. Future research should focus on designing new frailty screening tools specific to the PAD population.

Elevated Risk Analysis Index (RAI) Frailty Scores Are Independently Associated with Adverse Outcomes in Lower Extremity Surgical Revascularizations Similarly Across Genders. Ann Vasc Surg 2022; 87:47-56. [PMID: 35460856 DOI: 10.1016/j.avsg.2022.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 04/11/2022] [Accepted: 04/11/2022] [Indexed: 11/23/2022]
Abstract
INTRODUCTION The Risk Analysis Index (RAI) frailty scoring system, developed in a predominantly male Veteran sample, has recently undergone revision and external validation to become the RAI-rev using a general surgical sample from the American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) database. We set forth to evaluate the application of RAI-rev scoring to lower extremity surgical revascularization outcomes in the NSQIP database while verifying that similar associations with outcomes persist in this subset across genders. METHODS All elective cases in the NSQIP Targeted Lower Extremity Open (LEO) database recorded from 2015-2019 were paired with the NSQIP Participant User File using Case IDs. Groups were defined by EMR-recorded gender. Extended length of stay was defined as top quartile postoperative stays. Aggregate demographics, perioperative factors, and 30-day outcomes were compared between groups using unpaired t-test and Fisher's exact test. Adjusted odds-ratios (aOR) for each outcome were generated by applying a multivariate binary logistic regression model in IBM SPSSTM for five-point RAI-rev score increments from 25-45 and a most-frail group with scores >45. Covariates included surgical indication, prior ipsilateral surgical revascularization versus percutaneous intervention, graft utilization, presence of dirty/infected wound, smoking, hypertension, diabetes, and steroid use. A non-frail group with RAI-rev scores <25 was utilized as the reference for generating adjusted odds ratios. RESULTS 8,155 cases were recorded in the NSQIP LEO database from 2015-2019, including 2,498 (31%) performed in women who had slightly lower RAI-rev scores on average (22.1±5.8 vs 24.2±5.1; p=0.0001). Univariate trends demonstrated dose-dependent increases in frequency of most outcomes with rising frailty score ranges, with the most substantial changes over mortality (0.4% of non-frail to 14.7% most-frail), disposition to a skilled nursing facility (8% of non-frail to 27% most-frail), and extended length of stay (16% of non-frail to 44% most-frail). After adjusting for co-variates, patients with RAI-rev scores of 26-30 had aOR of 1.4 (95% CI: 1.2-1.6; p<0.001), 1.9 (95% CI: 1.6-2.2; p<0.001), and 2.4 (95% CI: 1.3-4.4; p<0.001) for extended stay, disposition to skilled nursing, and mortality respectively as compared to those with RAI-rev scores <25. Despite more non-significant aOR for women than men, trends were similar across genders in both univariate and multivariate analyses. CONCLUSION Our study is the first to find that outcomes other than mortality are significantly predicted by RAI-rev score ranges in lower extremity surgical revascularizations with similar associations regardless of gender. RAI-rev frailty scores >30 may help to identify frail patients at a higher risk of mortality, extended stay, and increased rehabilitation needs prior to lower extremity surgical revascularization to inform risk assessment and optimize patient recovery.

[PMID: 34793920 DOI: 10.1016/j.jvs.2021.10.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Accepted: 10/25/2021] [Indexed: 11/16/2022]
Abstract
OBJECTIVE Surgical frailty is strongly associated with increased perioperative morbidity and mortality. The risk analysis index (RAI) is a validated frailty score system, which has been shown to predict for short-term outcomes and long-term mortality in various surgical subspecialties. In the present study, we applied the frailty score to a veteran aneurysm population who had undergone nonemergent endovascular aortic aneurysm repair (EVAR). METHODS After obtaining institutional review board approval, the Veteran Affairs Surgical Quality Improvement Program data were queried for endovascular repair of infrarenal abdominal aortic aneurysm or dissection using the Current Procedural Terminology codes 34,800, 34,803, and 34,805 from 2001 to 2018. The preoperative variables were used to calculate the RAI score. The patients were placed into six cohorts according to the RAI score (≤20, 21-25, 26-30, 31-35, 35-40, and ≥41). The χ2 test and analysis of variance test were used compare the cohorts. Forward logistic regression modeling was used to determine the risks of each cohort. RESULTS From 2001 to 2018, 5568 patients had undergone EVAR. Of the 5568 patients, 99.6% were male, with a mean age of 71 ± 8 years. Of these patients, 4.5%, 43.8%, 33.9%, 11.7%, 4.2%, and 1.8% were included in the following RAI groups: ≤20, 21 to 25, 26 to 30, 31 to 35, 35 to 40, and ≥41, respectively. Frailty was associated with increased rates of overall complications, death, and an increased length of stay. When risk adjusted, frailty at the highest vs lowest level was associated with 2.7 times the odds of any complication developing and 4.4 times the odds of mortality ≤30 days. CONCLUSIONS Frailty, as determined by the RAI, was associated with postoperative outcomes in a dose-dependent manner. Frailty was associated with higher rates of major cardiac (myocardial infarction, cardiac arrest), pulmonary (pneumonia, failure to wean from ventilation, reintubation), renal (renal failure), overall complications, length of stay, and death. We recommend the use of this frailty index as a screening tool to guide discussions with patients scheduled to undergo EVAR.
