The impact of frailty as a critical mediator causing postoperative neurocognitive disorders in postoperative cardiac patients

Frailty is prevalent in elderly cardiac patients and may be a critical predictor of post-operative neurocognitive disorders (PND). The aim of this review was to demonstrate the correlation of frailty with PND in postsurgical elder patients. A review of published literature and bibliometric analysis was undertaken. Electronic databases from 2009 to 2022 were searched to identify articles that evaluated the relationship between frailty and PND in aging populations. Demographic data, type of surgery performed, frailty measurement, and impact of frailty on PND were extracted from the selected studies. The quality of the studies and risk of bias were assessed by the Newcastle-Ottawa Quality Assessment Scale, and the included articles were assessed as medium to high quality. Eighty-one studies were selected for the Bibliometric review in terms of research trends and hotpots. Additionally, 35 observational studies (prospective and retrospective cohorts) were selected for this review. The mean age ranged from 63 to 84 years and included patients undergoing cardiac, orthopedic, and other surgeries who had cardiac symptoms. Regardless of how frailty was measured, the strongest evidence in terms of numbers of studies, consistency of results, and study quality was for associations between frailty and PND. This analysis found a steadily growing focus on frailty and PND research in cardiac and other patients. The observational studies account for the majority of this area, and frailty occurred in the older cardiac patients over 60 years of age, and pre-screening of frailty can be predictive of PND and mortality.

Impact of preoperative frailty on the surgical and survival outcomes in older patients with solid cancer after elective abdominal surgery

BACKGROUND

Frailty is common in older patients with cancer; however, its clinical impact on the survival outcomes has seldom been examined in these patients. This study aimed to investigate the association of frailty with the survival outcomes and surgical complications in older patients with cancer after elective abdominal surgery in Taiwan.

METHODS

We prospectively enrolled 345 consecutive patients aged ≥65 years with newly diagnosed cancer who underwent elective abdominal surgery between 2016 and 2018. They were allocated into the fit, pre-frail, and frail groups according to comprehensive geriatric assessment (CGA) findings.

RESULTS

The fit, pre-frail, and frail groups comprised 62 (18.0%), 181 (52.5%), and 102 (29.5%) patients, respectively. After a median follow-up of 48 (interquartile range, 40-53) months, the mortality rates were 12.9%, 31.5%, and 43.1%, respectively. The adjusted hazard ratio was 1.57 (95% confidence interval [CI], 0.73-3.39; p = 0.25) and 2.87 (95% CI, 1.10-5.35; p = 0.028) when the pre-frail and frail groups were compared with the fit group, respectively. The frail group had a significantly increased risk for a prolonged hospital stay (adjusted odds ratio, 2.22; 95% CI, 1.05-4.69; p = 0.022) compared with the fit group.

CONCLUSION

Pretreatment frailty was significantly associated with worse survival outcomes and more surgical complications, with prolonged hospital stay, in the older patients with cancer after elective abdominal surgery. Preoperative frailty assessment can assist physicians in identifying patients at a high risk for surgical complications and predicting the survival outcomes of older patients with cancer.

Clinical impact of preoperative and postoperative sarcopenia on oncological outcomes in non-metastatic colorectal cancer

AIM

This study investigated the association between preoperative and postoperative changes in skeletal muscle mass and long-term oncological outcomes in patients with non-metastatic colorectal cancer.

METHOD

Patients who underwent surgery for Stages I-III colorectal cancer from January 2014 to December 2015 were included. Skeletal muscle mass was evaluated through preoperative and postoperative abdominopelvic CT scans. A multivariable analysis was conducted to determine the factors affecting disease-free survival rates.

RESULTS

A total of 238 patients were analysed. Forty-nine (25.9%) patients had preoperative sarcopenia. Patients with preoperative sarcopenia showed lower 3-year disease-free survival (58.5% vs. 78.4%, P = 0.001). Patients with postoperative sarcopenia also showed significantly lower 3-year disease-free survival compared to postoperative patients without sarcopenia at 6, 12 and 18 months, respectively (53.9% vs. 77.8%; 69.7% vs. 81.8%; 69.1% vs. 87.7%, P = 0.004). In a subgroup analysis, patients with both preoperative and postoperative sarcopenia showed the lowest 3-year disease-free survival rates (50.9%). The incidence of tumour recurrence was higher among the patients who had lost more skeletal muscle mass at 12, 18 and 24 months (-14.3 cm² /m² vs. -1.5 cm² /m² , P < 0.001; -24.5 cm² /m² vs. -1.1 cm² /m² , P < 0.001; and -31.6 cm² /m² vs. -1.4 cm² /m² , P < 0.001, respectively). A multivariable analysis demonstrated that the factors associated with disease-free survival included tumour stage, venous invasion, adjuvant chemotherapy, and preoperative or postoperative sarcopenia.

CONCLUSION

Not only preoperative but also postoperative sarcopenic changes adversely affect oncological outcomes following curative resection of colorectal cancer. Careful attention should be given to correcting sarcopenic status from the preoperative to the postoperative period.

Factors Related to Frailty in Older Cancer Patients Undergoing Colorectal Surgery: A Longitudinal Study

BACKGROUND

Frailty is common in older cancer patients undergoing colorectal surgery, but few studies have focused on frailty and its associations in this population.

OBJECTIVE

The aim of this study was to investigate the prevalence of frailty and its associations in older cancer patients undergoing colorectal surgery.

METHODS

A convenience sample of 88 cancer patients 60 years or older undergoing colorectal surgery was recruited from 1 medical center. Frailty, physical activity, functional status, anxiety, depression, and social support of the patients were assessed before surgery, at discharge post surgery, and at 1 month post surgery.

RESULTS

The prevalence of frailty in cancer patients undergoing colorectal surgery was 22.7% before surgery, decreased to 19.3% before discharge, and was 12.7% at 1 month after surgery. The proportion of prefrail patients significantly increased from 47.7% before surgery to 71.1% before discharge and was 64.6% at 1 month after surgery. Frail patients were more likely to be older and unmarried, have a lower albumin level, have lower physical activity, and be more dependent on others than nonfrail patients.

CONCLUSION

Older cancer patients undergoing colorectal surgery were more likely to be prefrail after surgery than before surgery. Assessment of frailty and its associated factors is necessary for older cancer patients undergoing colorectal surgery before and after surgery.

IMPLICATIONS FOR PRACTICE

Frailty may occur in cancer patients after colorectal surgery and is related to malnutrition and low physical activity. Appropriate discharge planning with physical activity tracking and an appropriate diet is encouraged to prevent frailty in cancer patients after colorectal surgery.

Acetyl-L-carnitine Slows the Progression from Prefrailty to Frailty in Older Subjects: A Randomized Interventional Clinical Trial

BACKGROUND

Ageing is characterized by a gradual decline in body function, representing the clinical situation called "frailty". Prefrailty is the intermediate stage between frailty and robust condition. L-carnitine (LC) plays an important role in energy production from long-chain fatty acids in mitochondria, and its serum level is lower in prefrail and frail subjects.

OBJECTIVE

This study aims to evaluate the effect of Acetyl-L-carnitine (ALCAR) in pre-frail older patients.

METHODS

We scheduled 3 months of treatment and then 3 months of follow-up. A total of 92 subjects were selected from May, 2009 to July, 2017, in a randomized, observational, double-blind, placebo-controlled study. We scheduled 3 months of treatment and then 3 months of follow-up. ALCAR (oral 1.5 g/bis in die - BID) or placebo groups were used.

RESULTS

After the treatment, only the treated group displayed a decrease in C reactive protein (CRP) p < 0.001 and an increase in serum-free carnitine and acetylcarnitine (p < 0.05) in Mini-Mental state (MMSE) p < 0.0001 and 6-walking distance (p < 0.0001); ALCAR group vs. placebo group showed a decrease in HDL cholesterol and CRP (p < 0.01), an increase in MMSE score (p < 0.001) and in the 6-walking distance (p < 0.001).

CONCLUSIONS

ALCAR treatment delays the incidence and severity of onset of degenerative disorders of the elderly in prefrail subjects with improvement in memory and cognitive processes.

Close Surgical Margins in Oral and Oropharyngeal Cancer: Do They Impact Prognosis?

Introduction. Mucosal margins exhibit a mean shrinkage of 30−40% after resection of oral and oropharyngeal cancers, and an adequate in situ surgical margin frequently results in a pathological close margin. However, the impact on prognosis remains unclear. We investigated the impact of a pathological close margin on disease-free survival (DFS) and overall survival (OS). Methods. We retrospectively reviewed the clinicopathological data of 418 patients diagnosed with squamous cell carcinomas of the oral cavity or oropharynx who underwent initial surgery (with curative intent) at our institute between 2010 and 2016. Results. Of the total population, the pathological marginal status of 290 (69.4%) patients was reported as clear (>5 mm), 61 (14.6%) as close (>1 mm, ≤5 mm), and 67 (16.0%) as positive (≤1 mm). The 5-year DFSs were 79.3%, 65.1%, and 52% in patients in the negative margin (group 1), close margin (group 2), and positive margin (group 3) groups, respectively. The difference between groups 1 and 2 was not significant (p = 0.213) but the difference between groups 2 and 3 was (p = 0.034). The 5-year OSs were 79.4%, 84%, and 52.3% in groups 1, 2, and 3, respectively. The difference between groups 1 and 2 was not significant (p = 0.824) but the difference between groups 2 and 3 was (p = 0.001). In multivariate analysis, older age, advanced T stage, and a positive margin were independently prognostic of the 5-year DFS and OS. Conclusion. In conclusion, the OS of patients with close margins was no different than that of others when appropriate postoperative adjuvant and/or salvage treatment were/was prescribed. However, we could not determine the impact of close margins on locoregional recurrence given various biases in our study setting. A future prospective study is needed.

Association of sarcopenia with a higher risk of infection in patients with type 2 diabetes

AIMS

This study aimed to determine whether patients with type 2 diabetes and sarcopenia had a higher risk of infection.

STUDY DESIGNS

A cross-sectional study and a follow-up study were performed.

METHOD

A total of 2562 patients were enrolled and assessed for body composition and infection status. They were classified into four groups according to body fat (BF) and muscle mass index (ASMI): obese, sarcopenic, sarcopenic obese, and normal. Among these, 275 patients were followed for a median follow-up period of 1.84 years to evaluate the relationship of changes in skeletal muscle with infection status.

RESULTS

The sarcopenic and sarcopenic obese groups showed a higher risk of infection, an increase by 49.6% (OR = 1.496, 95% CI 1.102-2.031) and 42.4% (OR = 1.424, 95% CI 1.031-1.967) compared with the normal group, and also had a higher risk of respiratory infection, an increase by 56.0% (OR = 1.560, 95% CI 1.084-2.246) and 57.4% (OR = 1.574, 95% CI 1.080-2.293), respectively. Patients with the increased ASMI (OR = 0.079, 95% CI 0.021-0.298) represented a lower risk of infection than those with the decreased ASMI. Even a minor change (OR = 0.125, 95% CI 0.041-0.378) against age was beneficial to lowering the risk of infection. However, no association was found in the changes of body mass index and BF with infection status.

CONCLUSIONS

Sarcopenia, especially in patients with diabetes who are also obese, increases the risk of infection. Maintaining or improving muscle mass is expected to reduce infections.

Usefulness of postoperative serum translocator protein as a predictive marker for delirium after breast cancer surgery in elderly women

Objective

Postoperative delirium (POD) has rarely been investigated in breast cancer patients. Herein, we assessed the association between serum levels of the inflammatory biomarker translocator protein (TP) and the occurrence of POD in breast cancer patients.

Methods

In this prospective, observational study, TP levels were detected in preoperative and postoperative serum samples from 152 elderly breast cancer patients, samples from 152 healthy elderly women, and samples from 152 elderly women with benign breast diseases. The relationship between serum TP levels and POD was investigated using multivariate analysis.

Results

TP levels in postoperative patient serum samples were significantly higher than in preoperative patient serum samples and serum from women in the two control groups. Postoperative serum TP levels were independently correlated with serum C-reactive protein levels and the occurrence of POD. Postoperative serum TP levels had a high discriminatory ability for POD under the receiver operating characteristic curve.

Conclusions

Increased postoperative serum TP levels are independently associated with the degree of inflammatory response and the risk of POD in elderly breast cancer patients, substantializing TP as an inflammatory biomarker that can efficiently discriminate POD after breast cancer surgery.

Frailty assessment and postoperative outcomes among patients undergoing general surgery

BACKGROUND

Frailty is an emerging concept in modern general surgery because of its correlation with adverse outcomes. More frail older patients are undergoing general surgery due to the rapid aging of the population and the effect of the "baby boom" generation. However, there is no consensus on the definition of frailty and on ways to assess its severity and effect.

PURPOSE

To describe the definition and epidemiology, measurement tools, and the effect of frailty on postoperative outcomes after general surgery.

METHODS

PubMed and Google Scholar databases were comprehensively searched.

RESULTS

Frailty is a syndrome defined as increased vulnerability to stressors due to a decline in physiological function and reserve among organ systems, resulting in adverse outcomes. Numerous tools have been described and tested for frailty measurement, but the ideal clinical tool has not been found yet. The evidence from cohort studies and meta-analyses shows associations between preoperative frailty and adverse perioperative outcomes after general surgery.

CONCLUSION

Frailty is an essential concept in general surgery. However, further studies have to identify the optimal way to preoperatively assess frailty and risk-stratify older patients.

Preoperative Risk Assessment: A Poor Predictor of Outcome in Critically ill Elderly with Sepsis After Abdominal Surgery

Background

Postoperative outcome prediction in elderly is based on preoperative physical status but its predictive value is uncertain. The goal was to evaluate the value of risk assessment performed perioperatively in predicting outcome in case of admission to an intensive care unit (ICU).

Methods

A total of 108 postsurgical patients were retrospectively selected from a prospectively recorded database of 144 elderly septic patients (>70 years) admitted to the ICU department after elective or emergency abdominal surgery between 2012 and 2017. Perioperative risk assessment scores including Portsmouth Physiological and Operative Severity Score for the enumeration of Mortality (P-POSSUM) and American Society of Anaesthesiologists Physical Status classification (ASA) were determined. Acute Physiology and Chronic Health Evaluation IV (APACHE IV) was obtained at ICU admission.

Results

In-hospital mortality was 48.9% in elderly requiring ICU admission after elective surgery (n = 45), compared to 49.2% after emergency surgery (n = 63). APACHE IV significantly predicted in-hospital mortality after complicated elective surgery [area under the curve 0.935 (p < 0.001)] where outpatient ASA physical status and P-POSSUM did not. In contrast, P-POSSUM and APACHE IV significantly predicted in-hospital mortality when based on current physical state in elderly requiring emergency surgery (AUC 0.769 (p = 0.002) and 0.736 (p = 0.006), respectively).

Conclusions

Perioperative risk assessment reflecting premorbid physical status of elderly loses its value when complications occur requiring unplanned ICU admission. Risks in elderly should be re-assessed based on current clinical condition prior to ICU admission, because outcome prediction is more reliable then.

Nutritional status and interventions for patients with cancer - A systematic review

BACKGROUND

Malnourishment is commonly seen in ageing, cancer and many chronic conditions, and is associated with poorer prognosis.

AIM

We set out to collect all currently available evidence on the association between nutritional status assessed with a validated screening tool and prognosis or course of treatment in older patients with cancer, and on the benefit of nutritional interventions in improving these outcomes.

METHODS

A systematic search in MEDLINE and EMBASE.

RESULTS

We included 71 studies on the association between nutritional status and outcome in (older) patients with cancer and 17 studies on the benefit of nutritional interventions in improving outcomes in this patient population. There is a significant association between nutritional status and increased intermediate- and long-term mortality (hazard ratio 1.87 (95% confidence interval 1.62-2.17). Those with poorer nutritional status were less likely to complete oncologic treatment according to plan and had higher health care consumption. Benefit of dietary interventions was limited although dietary counselling may lead to improved quality of life while nutritional support may lead to a decrease in post-operative complication rates.

CONCLUSION

Nutritional status is associated with poorer survival, decreased treatment completion and higher health care consumption and nutritional interventions are only able to negate these negatives outcome to a very limited degree.

Accuracy and Feasibility of Clinically Applied Frailty Instruments before Surgery

Background

A barrier to routine preoperative frailty assessment is the large number of frailty instruments described. Previous systematic reviews estimate the association of frailty with outcomes, but none have evaluated outcomes at the individual instrument level or specific to clinical assessment of frailty, which must combine accuracy with feasibility to support clinical practice.

Methods

The authors conducted a preregistered systematic review (CRD42019107551) of studies prospectively applying a frailty instrument in a clinical setting before surgery. Medline, Excerpta Medica Database, Cochrane Library and the Comprehensive Index to Nursing and Allied Health Literature, and Cochrane databases were searched using a peer-reviewed strategy. All stages of the review were completed in duplicate. The primary outcome was mortality and secondary outcomes reflected routinely collected and patient-centered measures; feasibility measures were also collected. Effect estimates were pooled using random-effects models or narratively synthesized. Risk of bias was assessed.

Results

Seventy studies were included; 45 contributed to meta-analyses. Frailty was defined using 35 different instruments; five were meta-analyzed, with the Fried Phenotype having the largest number of studies. Most strongly associated with: mortality and nonfavorable discharge was the Clinical Frailty Scale (odds ratio, 4.89; 95% CI, 1.83 to 13.05 and odds ratio, 6.31; 95% CI, 4.00 to 9.94, respectively); complications was associated with the Edmonton Frail Scale (odds ratio, 2.93; 95% CI, 1.52 to 5.65); and delirium was associated with the Frailty Phenotype (odds ratio, 3.79; 95% CI, 1.75 to 8.22). The Clinical Frailty Scale had the highest reported measures of feasibility.

Conclusions

Clinicians should consider accuracy and feasibility when choosing a frailty instrument. Strong evidence in both domains support the Clinical Frailty Scale, while the Fried Phenotype may require a trade-off of accuracy with lower feasibility.

High and low estimated glomerular filtration rates are associated with adverse outcomes in patients undergoing surgery for gastrointestinal malignancies

BACKGROUND

Abnormally high estimated glomerular filtration rates (eGFRs) are associated with endothelial dysfunction and frailty. Previous studies have shown that low eGFR is associated with increased morbidity, but few reports address high eGFR. The purpose of this study is to evaluate the association of high eGFR with surgical outcomes in patients undergoing surgery for gastrointestinal malignancies.

METHODS

We identified patients who underwent elective surgery for gastrointestinal malignancies from 2005 to 2015 in the American College of Surgeons National Surgical Quality Improvement Program database. We evaluated associations of eGFR with surgical outcomes by Cox or logistic models with restricted cubic spline functions, adjusting for case mix variables (i.e. age, gender, race and diabetes).

RESULTS

The median eGFR is 83 (interquartile range 67-96) mL/min/1.73 m2. Thirty-day mortality was 1.9% (2555/136 896). There is a U-shaped relationship between eGFR and 30-day mortality. The adjusted hazard ratios (95% confidence intervals) for eGFRs of 30, 60, 105 and 120 mL/min/1.73 m2 (versus 90 mL/min/1.73 m2) are 1.73 (1.52-1.97), 1.00 (0.89-1.11), 1.42 (1.31-1.55) and 2.20 (1.79-2.70), respectively. Similar associations are shown for other surgical outcomes, including return to the operating room and postoperative pneumonia. Subgroup analyses show that eGFRs both higher and lower than the respective medians are consistently associated with a higher risk of adverse outcomes across age, gender and race.

CONCLUSIONS

High and low eGFRs are associated with more adverse surgical outcomes in patients undergoing surgery for gastrointestinal malignancies. The eGFR associated with the lowest postoperative risk is approximately at the median eGFR of a given population.

Frailty and Sarcopenia in Older Patients Receiving Kidney Transplantation

Kidney transplantation is the treatment of choice for most of the patients with end-stage renal disease (ESRD). It improves quality of life, life expectancy, and has a lower financial burden to the healthcare system in comparison to dialysis. Every year more and more older patients are included in the kidney transplant waitlist. Within this patient population, transplanted subjects have better survival and quality of life as compared to those on dialysis. It is therefore crucial to select older patients who may benefit from renal transplantation, as well as those particularly at risk for post-transplant complications. Sarcopenia and frailty are frequently neglected in the evaluation of kidney transplant candidates. Both conditions are interrelated complex geriatric syndromes that are linked to disability, aging, comorbidities, increased mortality, and graft failure post-transplantation. Chronic kidney disease (CKD) and more importantly ESRD are characterized by multiple metabolic complications that contribute for the development of sarcopenia and frailty. In particular, anorexia, metabolic acidosis and chronic low-grade inflammation are the main contributors to the development of sarcopenia, a key component in frail transplant candidates and recipients. Both frailty and sarcopenia are considered to be reversible. Frail patients respond well to multiprofessional interventions that focus on the patients' positive frailty criteria, while physical rehabilitation and oral supplementation may improve sarcopenia. Prospective studies are still needed to evaluate the utility of formally measuring frailty and sarcopenia in the older candidates to renal transplantation as part of the transplant evaluation process.

A novel geriatric assessment tool that predicts postoperative complications in older adults with cancer

INTRODUCTION

Comprehensive geriatric assessment prior to oncologic surgery can help predict surgical outcomes. We tested whether an abbreviated geriatric assessment tool, the Vulnerable Elderly Surgical Pathways and outcomes Assessment (VESPA), would predict post-operative complications among older adults undergoing oncologic surgery.

METHOD

From 2008 to 2011, geriatric assessments were completed using the VESPA tool for patients age ≥ 70 seen in a pre-operative clinic. The VESPA assessed functional status, mood, cognition, and mobility, and can be completed in <10 min. We selected the subset of patients who underwent oncologic surgery and evaluated the VESPA's ability to predict post-operative surgical complications, geriatric complications (e.g., delirium), length of stay, and geriatric post-discharge needs (e.g., new functional dependence).

RESULTS

A total of 476 patients who underwent oncologic surgery received the assessment using VESPA. Compared to patients with low VESPA scores (<9), patients with high VESPA scores (≥9) had longer length of stay (mean 6.6 vs. 2.0 days; p < .001), more geriatric complications (39.5% vs. 5.7%; p < .001), more surgical complications (29.5% vs. 11.8%; p < .001), and more likely to have post discharge needs (76.0% vs. 31.7%; p < .001). Using logistic regression, each additional point on the VESPA scale was also associated with increased probability of geriatric complications (OR = 1.3; 95% CI = 1.2-1.4), surgical complications (OR = 1.2; 95% CI = 1.1-1.2), and geriatric post-discharge needs (OR = 1.3; 95% CI = 1.2-1.3).

CONCLUSION

The VESPA identifies older patients with cancer who are at risk for postoperative surgical and geriatric complications as well as functional needs at hospital discharge.

Frailty assessment: from clinical to radiological tools

Frailty is a syndrome of cumulative decline across multiple physiological systems, which predisposes vulnerable adults to adverse events. Assessing vulnerable patients can potentially lead to interventions that improve surgical outcomes. Anaesthesiologists who care for older patients can identify frailty to improve preoperative risk stratification and subsequent perioperative planning. Numerous clinical tools to diagnose frailty exist, but none has emerged as the standard tool to be used in clinical practice. Radiological modalities, such as computed tomography and ultrasonography, are widely performed before surgery, and are therefore available to be used opportunistically to objectively evaluate surrogate markers of frailty. This review presents the importance of frailty assessment by anaesthesiologists; lists common clinical tools that have been applied; and proposes that utilising radiological imaging as an objective surrogate measure of frailty is a novel, expanding approach for which anaesthesiologists can significantly contribute to broad implementation.

Predictive value of each geriatric assessment domain for older patients with cancer: A systematic review

BACKGROUND

A geriatric assessment (GA) is increasingly used to help guide treatment decisions in older patients with cancer. However, there is no consensus regarding which domains should be included in the GA. In addition, the field of geriatric oncology moves very fast and as a result many new studies have been published since the last review in 2015. Therefore, the objective of this systematic review is to evaluate which domains of the GA could predict patient-related treatment outcomes of older patients with cancer and thereby should be included in a GA.

METHODS

A systematic literature search was performed for publications in English or Dutch between September 2006 and July 2017 addressing the association between individual domains of the GA and mortality, postoperative complications, or systemic treatment-related outcomes in older patients with cancer.

RESULTS

Eight different domains were evaluated in 46 publications, namely functional status, nutritional status, cognition, mood, physical function, fatigue, social support, and falls. All eight domains were predictive for at least one of the investigated outcomes but the results were quite variable across studies. Physical function and nutritional status were the domains most often associated with mortality and systemic treatment-related outcomes, and the domain physical function was most often associated with postoperative complications.

CONCLUSION

Overall, this review demonstrates that the GA should minimally consist of physical function and nutritional status, when the aim is to predict patients-related outcomes of older patients with cancer, although the results are quite heterogeneous. For the other domains, the findings are too inconsistent to draw conclusions about their overall predictive ability.

Frailty in geriatric head and neck cancer: A contemporary review

OBJECTIVE

To provide a summary of the current frailty literature relating to head and neck cancer.

DATA SOURCES

Ovid MEDLINE, PubMed, Google Scholar.

METHODS

A comprehensive review of the literature was performed from 2000 to 2017 using key words frailty, elderly, geriatric, surgery, otolaryngology, head and neck cancer.

RESULTS

The aging population has led to an increased diagnosis of head and neck cancer in elderly patients. The prevalence of comorbidities, disabilities, geriatric syndromes and social issues can make treatment planning and management in this population challenging. Chronological age alone may not be the optimal approach to guiding treatment decisions, as there is marked heterogeneity amongst this age group. Individualization of treatment can be achieved by assessing for the presence of frailty, which has growing evidence as an important marker of health status in geriatric oncology. Frailty is a complex geriatric syndrome characterized by a state of increased vulnerability to stressors and is associated with morbidity, mortality, and treatment toxicity. Screening for frailty may provide an efficient method to identify those who would benefit from further assessment or pretreatment optimization, and to provide prognostic information to assist clinicians and patients in formulating the most ideal treatment plan for the elderly individual with head and neck cancer.

CONCLUSIONS

Frailty has emerged as an important concept in geriatric oncology, with wide significance in head and neck cancer. Incorporating frailty assessments into clinical practice may provide otolaryngologists pertinent information regarding health status and outcomes leading to optimal care of the elderly cancer patient.

Urinary tract infections in a geriatric sub-acute ward-health correlates and atypical presentations

Purpose

Bacterial urinary tract infections (UTIs) are the most frequently occurring infectious diseases in the geriatric population. The aim of the study was to determine the prevalence and clinical features of UTIs in geriatric in-patients and their association with health and functional ability characteristics.

Methods

A prospective cross-sectional cohort study was conducted among patients hospitalized on the geriatric ward. Patients were interviewed, examined, and had their hospital records analyzed. An uncontaminated midstream urine sample was collected and cultured in all of the cases suspected for UTI. Relative risks for UTI were counted and multivariable logistic regression model was built.

Results

246 patients were included, 179 (72.8%) women, 210 (85.4%) 75 + -year-olds. Bacterial UTIs occurred in 18.3% of the patients. The main etiological agent was Escherichia coli (73.3%). The most significant predictors of UTI were recurrent UTI and urinary catheter. The typical clinical UTI symptoms occurred in less than half of the cases (only in 11.1% of cases fever was observed). More often, than in patients without UTIs, they reported symptoms such as delirium (28.9% vs. 18%), tachycardia (11.1% vs. 1.5%) or hypotension (20% vs. 12.1%).

Conclusions

Bacterial UTIs affect about 1/5 of hospitalized geriatric patients. The clinical picture of these infections very often is atypical and it indicates a need for diagnostic vigilance.

Simple Method of Screening for Frailty in Older Adults Using a Chronometer and Tape Measure in Clinic

OBJECTIVES

Detecting frailty in older adults scheduled for surgery is important to predict the occurrence of adverse outcomes, but because of its complexity, frailty screening is not commonly performed. The objective of the current study was to assess whether frailty can be screened for using automatically measured usual gait speed (UGS) and mid-arm circumference (MAC) in the outpatient clinic.

DESIGN

Prospective, cross-sectional study.

SETTING

Geriatric center of a tertiary hospital.

PARTICIPANTS

Outpatients aged 65 and older (N = 113).

MEASUREMENTS

Frailty status was evaluated according to a multidimensional frailty score (MFS) using a comprehensive geriatric assessment, and participants were classified into 5 categories. UGS was evaluated by having participants walk through the clinic using an automated laser-gated chronometer. MAC was recorded using a tape measure on a blood pressure cuff. Correlations between these two physical measurements and MFS were assessed.

RESULTS

The mean age of the 93 participants who successfully underwent UGS evaluation was 75.8 ± 4.7; 35 were male. In this population, the mean Charlson Comorbidity Index was 2.2 ± 1.4, mean MFS was 4.1 ± 2.0, and 20 participants were considered to be at high risk of experiencing adverse outcomes. Mean UGS was 0.75 ± 0.16 m/s, and mean MAC was 31.2 ± 1.9 cm); both physical parameters were correlated with MFS (UGS: standardized beta = -0.420, P < .001; MAC: standardized beta = -0.457, P < .001). Using UGS and MFS, the area under curve of receiver operating curve for determining which participants were at high risk of experiencing adverse outcomes was 0.809 (P < .001).

CONCLUSION

UGS and MAC are viable methods of clinically screening for frailty.

A Review of Frailty Syndrome and Its Physical, Cognitive and Emotional Domains in the Elderly

Background: Frailty, a very important complication of increasing age, is a well-recognised concept although it has not been accurately measured in the clinical setting. The aim of this literature review is to summarise commonly used frailty screening tools, and to describe how new measurement methods have been developed recently. Methods: Several frailty measurement tools including the most cited and newly developed scales have been described in this review. We searched the MEDLINE using the search terms; “frailty score, scale, tool, instrument, index, phenotype” and then summarised selected tools for physical, cognitive, emotional and co-morbidity domains. Results: The most cited frailty measurement methods developed from 1999 to 2005 are primarily criteria for physical frailty (e.g., frailty phenotype). More recently developed tools (e.g., triad of impairment and multidimensional frailty score) consider cognitive and emotional domains in addition to physical deficit in measuring frailty. Co-morbidity has also been considered as a domain of frailty in several measurement tools. Conclusion: Although frailty tools have traditionally assessed physical capability, cognitive and emotional impairment often co-exist in older adults and may have shared origins. Therefore, newer tools which provide a composite measure of frailty may be more relevant for future use.

Is Frailty a Modifiable Risk Factor of Future Adverse Outcomes in Elderly Patients with Incident End-Stage Renal Disease?

Little is known about the clinical significance of frailty and changes of frailty after dialysis initiation in elderly patients with end-stage renal disease (ESRD). We prospectively enrolled 46 elderly patients with incident ESRD at a dialysis center of a tertiary hospital between May 2013 and March 2015. Frailty was assessed by using a comprehensive geriatric assessment protocol and defined as a multidimensional frailty score of ≥ 10. The main outcome was the composite of all-cause death or cardiovascular hospitalization, as determined in June 2016. The median age of the 46 participants was 71.5 years, and 63.0% of them were men. During the median 17.7 months follow-up, the rate of composite outcome was 17.4%. In multivariate logistic regression analysis, after adjusting for age, sex, diabetes, body mass index (BMI), and time of predialytic nephrologic care, female sex, and increased BMI were associated with increased and decreased odds of frailty, respectively. In multivariate Cox proportional hazards analysis, after adjusting for age, sex, diabetes, BMI, and time of predialytic nephrologic care, frailty was significantly associated with the composite adverse outcome. In repeated frailty assessments, the multidimensional frailty score significantly improved 12 months after the initiation of dialysis, which largely relied on improved nutrition. Therefore, frailty needs to be assessed for risk stratification in elderly patients with incident ESRD.

Leading Comorbidity associated with 30-day post-anesthetic mortality in geriatric surgical patients in Taiwan: a retrospective study from the health insurance data

Background

Elderly patients with aged physical status and increased underlying disease suffered from more postoperative complication and mortality. We design this retrospective cohort study to investigate the relationship between existing comorbidity of elder patients and 30 day post-anesthetic mortality by using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) from Health Insurance Database.

Methods

Patients aged above 65 years old who received anesthesia between 2000 and 2010 were included from 1 million Longitudinal Health Insurance Database in (LHID) 2005 in Taiwan. We use age, sex, type of surgery to calculate propensity score and match death group and survival one with 1:4 ratio (death: survival = 1401: 5823). Multivariate logistic model with stepwise variable selection was employed to investigate the factors affecting death 30 days after anesthesia.

Results

Thirty seven comorbidities can independently predict the post-anesthetic mortality. In our study, the leading comorbidities predict post-anesthetic mortality is chronic renal disease (OR = 2.806), acute myocardial infarction (OR = 4.58), and intracranial hemorrhage (OR = 3.758).

Conclusions

In this study, we present the leading comorbidity contributing to the postoperative mortality in elderly patients in Taiwan from National Health Insurance Database. Chronic renal failure is the leading contributing comorbidity of 30 days mortality after anesthesia in Taiwan which can be explained by the great number of hemodialysis and prolong life span under National Taiwan Health Insurance. Large scale database can offer enormous information which can help to improve quality of medical care.

Systematic review and meta-analysis of frailty as a predictor of morbidity and mortality after major abdominal surgery

BACKGROUND

Frailty is associated with poor prognosis, but the multitude of definitions and scales of assessment makes the impact on outcomes difficult to assess. The aim of this study was to quantify the effect of frailty on postoperative morbidity and mortality, and long-term mortality after major abdominal surgery, and to evaluate the performance of different frailty metrics.

METHODS

An extended literature search was performed to retrieve all original articles investigating whether frailty could affect outcomes after elective major abdominal surgery in adult populations. All possible definitions of frailty were considered. A random-effects meta-analysis was carried out for all outcomes of interest. For postoperative morbidity and mortality, overall effect sizes were estimated as odds ratios (OR), whereas the hazard ratio (HR) was calculated for long-term mortality. The potential effect of the number of domains of the frailty indices was explored through meta-regression at moderator analysis.

RESULTS

A total of 35 studies with 1 153 684 patients were analysed. Frailty was associated with a significantly increased risk of postoperative major morbidity (OR 2·56, 95 per cent c.i. 2·08 to 3·16), short-term mortality (OR 5·77, 4·41 to 7·55) and long-term mortality (HR 2·71, 1·63 to 4·49). All domains were significantly associated with the occurrence of postoperative major morbidity, with ORs ranging from 1·09 (1·00 to 1·18) for co-morbidity to 2·52 (1·32 to 4·80) for sarcopenia. No moderator effect was observed according to the number of frailty components.

CONCLUSION

Regardless of the definition and combination of domains, frailty was significantly associated with an increased risk of postoperative morbidity and mortality after major abdominal surgery.

Prediction of Mortality and Postoperative Complications using the Hip-Multidimensional Frailty Score in Elderly Patients with Hip Fracture

High mortality and dependent living after hip fracture pose a significant public health concern. Retrospective study was conducted with 481 hip fracture patients (≥65 years of age) undergoing surgery from March 2009 to May 2014. The Hip-MFS was calculated by Comprehensive Geriatric Assessment (CGA). The primary outcome was the 6-month all-cause mortality rate. The secondary outcomes were 1-year all-cause mortality, postoperative complications and prolonged hospital stay, and institutionalization. Thirty-five patients (7.3%) died within 6 months after surgery (median [interquartile range], 2.9 [1.4-3.9] months). The fully adjusted hazard ratio per 1 point increase in Hip-MFS was 1.458 (95% confidence interval [CI]: 1.210-1.758) for 6-months mortality and odds ratio were 1.239 (95% CI: 1.115-1.377), 1.156 (95% CI: 1.031-1.296) for postoperative complications and prolonged total hospital stay, respectively. High-risk patients (Hip-MFS > 8) showed higher risk of 6-month mortality (hazard ratio: 3.545, 95% CI: 1.466-8.572) than low-risk patients after adjustment. Hip-MFS successfully predict 6-month mortality, postoperative complications and prolonged hospital stay in elderly hip fracture patients after surgery. Hip-MFS more precisely predict 6-month mortality than age or existing tools (P values of comparison of ROC curve: 0.002, 0.004, and 0.044 for the ASA classification, age and NHFS, respectively).

Clinical implication of frailty assessment in older patients with atrial fibrillation

BACKGROUND

We aimed to show the frailty status in older AF patients, and to find the association between frailty and the scores of CHA₂DS₂-VASc and HAS-BLED. Ultimately, we sought to investigate the impact of frailty on cardiovascular and all-cause mortality in older AF patients.

METHODS

We retrospectively evaluated 365 patients (≥65years old) with AF, who underwent comprehensive geriatric assessment (CGA) between 2007 and 2014 in a single tertiary hospital. The CHA₂DS₂-VASc and HAS-BLED scores were calculated based on the electronic medical records and the frailty index was computed from the CGA data. The primary outcomes were cardiovascular and all-cause mortality.

RESULTS

Frailty status was positively associated with the CHA₂DS₂-VASc score (P<0.001) and the HAS-BLED score (P=0.01). Patients with high CHA₂DS₂-VASc and HAS-BLED scores were more likely to be treated with anticoagulants rather than antiplatelet agents. However, frailty status was not associated with antithrombotic therapy. During the follow-up period (median [interquartile range], 22.9 [8.4-42.2] months), 141 patients (38.6%) died, of which 48 were due to cardiovascular events. CHA₂DS₂-VASc score could predict cardiovascular mortality, but not all-cause mortality. In contrast, frailty status was the independent predictor for both cardiovascular and all-cause mortality after adjusting for possible confounders (hazard ratio for all-cause mortality, 4.549; 95% CI, 2.756-7.509; P<0.001).

CONCLUSION

Frailty assessment can be used to predict mortality in older AF patients, and provides additional prognostic value, along with the CHA₂DS₂-VASc and HAS-BLED scores.

Prehabilitation in our most frail surgical patients: are wearable fitness devices the next frontier?

PURPOSE OF REVIEW

Frailty is the concept of accumulating physiologic declines that make people less able to deal with stressors, including surgery. Prehabilitation is intervention to enhance functional capacity before surgery. Frailty and prehabilitation among transplant populations and the role of wearable fitness tracking devices (WFTs) in delivering fitness-based interventions will be discussed.

RECENT FINDINGS

Frailty is associated with increased complications, longer length of hospital stay and increased mortality after surgery. Frail kidney transplant patients have increased delayed graft function, mortality and early hospital readmission. Frail lung or liver transplant patients are more likely to delist or die on the waitlist. Prehabilitation can mitigate frailty and has resulted in decreased length of hospital stay and fewer postsurgical complications among a variety of surgical populations. Increasingly, WFTs are used to monitor patient activity and improve patient health. Interventions using WFTs have resulted in improved activity, weight loss and blood pressure.

SUMMARY

Frailty is a measurable parameter that identifies patients at risk for worse health outcomes and can be mitigated through intervention. Prehabilitation to reduce frailty has been shown to improve postsurgical outcomes in a variety of populations. WFTs are being integrated in healthcare delivery for monitoring and changing health behavior with promising results.

[Perioperative risk and mortality after major surgery]

Although anesthesia-associated mortality has been significantly reduced down to 0.00068-0.00082% over the last decades, recent studies have revealed a high perioperative mortality of 0.8- 4%. Apart from anesthesia and surgery-induced major complications, perioperative mortality is primarily negatively influenced by individual patient comorbidities. These risk factors predispose for acute critical incidents (e.g., myocardial infarction); however, the majority of fatal complications are a result of slowly progressing conditions, particularly infections or the sequelae of systemic inflammation. This implicates a broad window of opportunity for the detection and treatment of slow-onset complications to improve the perioperative outcome. The term "failure to rescue" (FTR), i.e., the proportion of patients who die from major complications compared to the number of all patients with complications, has been introduced as a valid indicator for the quality of perioperative care. Growing evidence has already shown that FTR is an underestimated factor in perioperative medicine accounting for or at least being involved in the development of postoperative mortality. While the incidence of severe postoperative complications amazingly does not show much variation between hospitals, FTR shows significant differences implying a major potential for improvement. With 14 million surgical procedures per year in Germany, a postoperative mortality of approximately 1% and an avoidable FTR rate of 40% mean that there are an estimated 60,000 preventable deaths per year. Hence, in the future it will be imperative to (1) identify patients at risk, (2) to prevent the development of postoperative complications with the use of adequate adjunctive therapeutic strategies, (3) to establish surveillance and monitoring systems for the early detection of postoperative complications and (4) to treat postoperative complications efficiently and in time when they arise.

Comprehensive geriatric assessment in patients with gastric and gastroesophageal adenocarcinoma undergoing gastrectomy

OBJECTIVE

The purpose of this study was to identify clinical and geriatric assessment variables associated with outcome in patients with gastric adenocarcinoma who have undergone gastrectomy.

METHODS

We reviewed demographic, clinical, and geriatric assessment variables, including recent falls, pain, performance status, American Society of Anesthesiologists score, assistive device use, comorbidity, polypharmacy, and weight change, for patients undergoing gastrectomy between 2005 and 2014. Outcome variables included morbidity, mortality, hospital length of stay, and readmission.

RESULTS

Of 279 patients, 133 (48%) underwent total gastrectomy. The 90-day major morbidity rate was 24% and the mortality rate was 1%. Length of hospital stay ≥ 14 days occurred in 38%, with readmission within 30 days in 13%. On multivariate analysis, gastroesophageal junction involvement, (odds ratio [OR] 2.5, 95% confidence interval [1.1-5.8]), additional organ resection, (OR 3.2, [1.6-6.3]), pain score >0 (OR 3.8, [1.6-8.7]), Eastern Cooperative Oncology Group performance status >0, (OR 2.3, [1.2-4.6]), and polypharmacy (OR 2.4, [1.1-5.2]) were associated with major morbidity. Hospital stay ≥ 14 days was associated with age ≥ 75 years (OR 3.9, [1.7-9.2]), total gastrectomy (OR 3.5, [2.0-6.3]), performance status >0 (OR 1.8, [1.0-3.2]), and preoperative chemotherapy (OR 0.3, [0.2-0.7]).

CONCLUSIONS

Future studies are needed to identify methods to improve performance status, as this may improve postoperative complications and resource utilization.
