Frailty for Surgeons: Review of a National Institute on Aging Conference on Frailty for Specialists

Unveiling the multi-dimensional frailty network among older cancer survivors in China: A network analysis study

INTRODUCTION

Frailty has a significant impact on the overall quality of life of older cancer survivors, but the relationships among frailty symptoms are not well understood. This study aims to explore the specific associations among multidimensional symptoms of frailty among older cancer survivors by employing network analysis to provide supportive evidence for targeted interventions in the future.

MATERIALS AND METHODS

Data were obtained by cluster sampling from three large Grade-A tertiary hospitals in Shandong Province, China, and collected through face-to-face interviews by trained investigators. We included patients who were diagnosed with a solid malignant tumor at the age of 60 years or older. Frailty indicators were measured by the Groningen Frailty Indicator (GFI) and analyzed primarily through network analysis, including network estimation, centrality, and stability analysis. The relative importance of a node in a network was tested by centrality analyses, and Spearman correlations were applied to estimate the relationships between symptom pairs (symptom score) and symptom clusters (standardized symptom score) in the symptom network. In terms of centrality, the indexes of strength, closeness, and betweenness were adopted to measure the importance of nodes.

RESULTS

Five hundred and eight older cancer survivors were included, with an average age of 68.4 years (standard deviation [SD] = 5.4), and a higher proportion were male (n = 307[60.4%]). The prevalence of frailty among older cancer survivors was 58.9% (n = 299), with a mean GFI score of 4.46 (SD = 2.87). The strongest edge was between "dressing and undressing" and "going to the toilet" (r = 0.58). The nodes with the higher strength centrality were "going to the toilet" (rS=1.09), "walking around outside" (rS=0.97), and "part of social network" (rS=0.96); and the nodes with the higher closeness centrality were "mark physical fitness" (rC=0.005), "calm and relaxed" (rC=0.005), and "nervous or downhearted" (rC=0.005).

DISCUSSION

This study demonstrated that older cancer survivors in China have a high prevalence of frailty, with self-care and social participation-related symptoms playing a key role in the multidimensional network of frailty symptoms. Psychological symptoms can rapidly influence other symptoms within this network. Therefore, prioritizing psychological symptoms in the assessment of older adults with cancer is essential for effective frailty management.

Implications of frailty before and after intensive care unit admission

PURPOSE OF REVIEW

In the decade since the first publications related to frailty in those with critical illness, the study of frailty has rapidly increased. The purpose of this review is to update the reader on recent advances across several important areas of frailty research: how best to identify frailty in those with critical illness, studies describing the relationship between frailty and delirium, and how frailty affects outcomes for those with coronavirus disease 2019 (COVID-19), which, despite rates and severity of acute infection declining, still tremendously impacts patients long after the acute infection, resulting in symptoms of long COVID-19.

RECENT FINDINGS

A number of frailty assessment tools exist, to date, the Clinical Frailty Scale based on the deficit accumulation approach to defining frailty, is the most commonly used in ICU studies. Several novel frailty instruments for the ICU are being developed. Because tools assessing frailty by the phenotypic and deficit accumulation approaches identify different populations, careful choice of a frailty assessment tool is warranted.Frailty and delirium are hypothesized to represent different clinical expressions of a similar underlying vulnerability, thus identifying frailty may be a useful means by which to identify patients at high risk of becoming delirious. Recent studies show that frailty at ICU admission is a predictor of the development of delirium.Finally, frailty and its outcomes were studied in patients with COVID-19. As with other causes of critical illness, frailty was highly prevalent in those admitted to the ICU and is associated with greater mortality. Frailty was also associated with increased decisions to limit life support treatments, but these decisions were not different among those admitted with COVID-19 or for other reasons.

SUMMARY

Frailty in those with critical illness is an emerging field of study. Future work to define the optimal means by which to identify this syndrome and how best to manage critically ill patients with frailty are needed.

How can we approach preoperative frailty and related factors in patients with cancer? A scoping review

AIM

To identify factors related to preoperative frailty in patients with cancer and map the tools that measure frailty.

DESIGN

A Scoping review.

METHODS

This scoping review based on Arksey and O'Malley's framework. Articles from CINAHL, PubMed, EMBASE, and PsycINFO databases published between January 2011 and April 2021. The searched keywords were concepts related to 'cancer', 'frailty' and 'measurement'.

RESULTS

While 728 records were initially identified, 24 studies were eventually selected. Research on frailty was actively conducted between 2020 and 2021. Factors related to preoperative frailty were age (22.9%), sex (11.4%), body mass index (11.4%) and physical status indicators (54.3%). The most common result of preoperative frailty was postoperative complications (35.0%). 24 instruments were used to measure frailty.

IMPLICATIONS FOR PATIENT CARE

Selecting an appropriate preoperative frailty screening tool can help improve patient postoperative treatment outcomes.

IMPACT

There are many instruments for assessing preoperative frailty, each evaluating a multi-dimensional feature. We identified the frailty screening tools used today, organized the factors that affect frailty, and explored the impact of frailty. Identifying and organizing frailty measurement tools will enable appropriate evaluation.

Comparison of the frailty index and frailty phenotype and their associations with postoperative delirium incidence and severity

BACKGROUND

Recent studies have reported an association between presurgical frailty and postoperative delirium. However, it remains unclear whether the frailty-delirium relationship differs by measurement tool (e.g., frailty index vs. frailty phenotype) and whether frailty is associated with delirium, independent of preoperative cognition.

METHODS

We used the successful aging after elective surgery (SAGES) study, a prospective cohort of older adults age ≥70 undergoing major non-cardiac surgery (N = 505). Preoperative measurement of the modified mini-mental (3MS) test, frailty index and frailty phenotype were obtained. The confusion assessment method (CAM), supplemented by chart review, identified postoperative delirium. Delirium feature severity was measured by the sum of CAM-severity (CAM-S) scores. Generalized linear models were used to determine the relative risk of each frailty measure with delirium incidence and severity. Subsequent models adjusted for age, sex, surgery type, Charlson comorbidity index, and 3MS.

RESULTS

On average, patients were 76.7 years old (standard deviation 5.22), 58.8% of women. For the frailty index, the incidence of delirium was 14% in robust, 17% in prefrail, and 31% in frail patients (p < 0.001). For the frailty phenotype, delirium incidence was 13% in robust, 21% in prefrail, and 27% in frail patients (p = 0.016). Frailty index, but not phenotype, was independently associated with delirium after adjustment for comorbidities (relative risk [RR] 2.13, 95% confidence interval [CI] 1.23-3.70; RR 1.61, 95% CI 0.77-3.37, respectively). Both frailty measures were associated with delirium feature severity. After adjustment for preoperative cognition, only the frailty index was associated with delirium incidence; neither index nor phenotype was associated with delirium feature severity.

CONCLUSION

Both the frailty index and phenotype were associated with the development of postoperative delirium. The index showed stronger associations that remained significant after adjusting for baseline comorbidities and preoperative cognition. Measuring frailty prior to surgery can assist in identifying patients at risk for postoperative delirium.

Avoiding Locoregional Overtreatment in Older Adults With Early-Stage Breast Cancer

Advances in the treatment of older women with early-stage breast cancer, particularly opportunities for de-escalation of therapy, have afforded patients and providers opportunity to individualize care. As the majority of women ≥65 have estrogen receptor-positive, HER2-negative disease, locoregional therapy (surgery and/or radiation) may be tailored based on a patient's physiologic age to avoid either over- or undertreatment. To determine who would derive benefit from more or less intensive therapy, an accurate assessment of an older patient's physiologic age and incorporation of patient-specific values are paramount. While there now exist well-validated geriatric assessment tools whose use is encouraged by the American Society of Clinical Oncology when considering systemic therapy, these instruments have not been widely integrated into the locoregional breast cancer care model. This review aims to highlight the importance of assessing frailty and the concepts of and over- and undertreatment, in the context of trial data supporting opportunities for safe deescalation of locoregional therapy, when treating older women with early-stage breast cancer.

NSQIP 5-factor modified frailty index and complications after ileal anal pouch anastomosis for ulcerative colitis

Background

Frailty has been associated with worse postoperative outcomes. The 5-factor modified frailty index (mFI-5) is an objective measure although its validity in measuring frailty in patients undergoing ileal pouch-anal anastomosis (IPAA) for chronic ulcerative colitis (CUC) has not been reported.

Methods

This study used the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) targeted proctectomy database. The mFI-5 was calculated by five preoperative diagnoses: insulin-dependent or noninsulin-dependent diabetes, congestive heart failure, hypertension, chronic obstructive pulmonary disease, and dependent or partially dependent functional status. The impact of mFI-5 on minor and major postoperative morbidity in CUC patients undergoing IPAA was analyzed.

Results

The cohort included 1454 patients (median age 38 years, median body mass index [BMI] 26 kg/m2) of which 87 % had a mFI-5 = 0, 11 % had a mFI-5 = 1, and 2.5 % a mFI-5 ≥ 2. In multivariable logistic regression, mFI-5 ≥ 2 was significantly associated with minor complications (OR = 2.29, 95 % CI [1.00-5.22], p = 0.049), but not with major complications (p = 0.860).

Conclusion

IPAA for CUC is associated with high postoperative morbidity, however, the mFI-5 alone has limited utility in determining which patients are at a higher risk of complications due to frailty. These observations suggest there is a need for more relevant instruments to measure frailty in this patient cohort.

Enhancing surgical outcomes in elderly gastric cancer patients: the role of comprehensive preoperative assessment and support

BACKGROUND

As the prevalence of gastric cancer rises in aging populations, managing surgical risks and comorbidities in elderly patients presents a unique challenge. The Comprehensive Preoperative Assessment and Support (CPAS) program, through comprehensive preoperative assessments, aims to mitigate surgical stress and improve outcomes by enhancing patient awareness and preparation. This study investigates the efficacy of a CPAS program, incorporating frailty and sarcopenia evaluations, to improve short-term outcomes in elderly gastric cancer patients.

METHODS

A retrospective analysis was conducted on 127 patients aged 75 or older who underwent surgery with CPAS between 2018 and August 2023, compared to 170 historical controls from 2012 to 2017. Propensity score matching balanced both groups based on age-adjusted Charlson Comorbidity Index and surgical details. The primary focus was on the impact of CPAS elements such as rehabilitation, nutrition, psychological support, oral frailty, and social support on short-term surgical outcomes.

RESULTS

Among 83 matched pairs, the CPAS group, despite 40.4% of patients in the CPAS group and 21.2% in the control group had an ASA-PS score of 3 or higher (P < 0.001), demonstrated significantly reduced blood loss (100 ml vs. 190 ml, P = 0.026) and lower incidence of serious complications (19.3% vs. 33.7%, P = 0.034), especially in infections and respiratory issues. Sarcopenia was identified in 38.6% of CPAS patients who received tailored support. Additionally, the median postoperative hospital stay was notably shorter in the CPAS group (10 days vs. 15 days, P < 0.001), with no in-hospital deaths. These results suggest that personalized preoperative care effectively mitigates operative stress and postoperative complications.

CONCLUSION

Implementing CPAS significantly enhances surgical safety and reduces complication rates in elderly gastric cancer patients, emphasizing the critical role of personalized preoperative care in surgical oncology for this demographic.

Factors Predicting 90-Day Readmissions for US Older Adult Burn Patients From the 2016-2018 Nationwide Readmissions Database

Older adults with burn injuries have a high risk of readmission after the initial burn admission. Frailty is associated with poor outcomes from the initial burn injury, however, it remains unknown if frailty impacts readmission in older adults after the initial index burn admission. Our study aims to examine patient, frailty, burn, surgical, and hospital factors that contribute to 90-day readmissions in older adults with an acute burn. Patients ≥ 50 years of age with an acute burn diagnosis in the Nationwide Readmissions Database (2016-2018) were included. Patients who died during index admissions were excluded from the readmission analysis. Patient, burn, hospital stay, and hospital characteristics were analyzed. Using variables significant from univariate logistic regression analysis, we performed a multivariable logistic regression analysis to identify factors associated with 90-day readmissions. A total of 41,500 weighted index burn admissions were included. The 90-day readmission rate was 25.6% (10,641/41,500). Almost all the readmissions were unplanned (96.5%). The most common primary readmission diagnoses based on Clinical Classifications Software Refined were burn injury and septicemia. Multivariable logistic regression analysis demonstrated an increased hospital frailty risk and lower-body-only burns were associated with an increased risk of readmission. Notably, surgical treatment of the burn injury during the index admission was associated with a decreased risk of readmission. This highlights the importance and challenges of surgical decision-making for older adults with high comorbidity burden. Future studies are needed to develop decision guides to help clinicians identify patients who would benefit from surgical treatment versus more conservative strategies in older adult patients with burns.

Value of a multidisciplinary geriatric oncology committee on patient care in a community-based, academic cancer center

INTRODUCTION

The heterogeneity in health and functional ability among older patients makes the management of cancer a unique challenge. The Geriatric Oncology Program at the University of Maryland Baltimore Washington Medical Center (BWMC) was created to optimize cancer management for older patients. This study aimed to assess the benefits of the implementation of such a program at a community-based academic cancer center.

MATERIALS AND METHODS

We analyzed patients aged ≥80 years presenting to the Geriatric Oncology Program between 2017 and 2022. A multidisciplinary team of specialists collectively reviewed each patient using geriatric-specific domains and stratified each patient into one of three management groups- Group 1: those deemed fit to receive standard oncologic care (SOC); Group 2: those recommended to receive optimization services prior to reassessment for SOC; and Group 3: those deemed to be best suited for supportive care and/or hospice care.

RESULTS

The study cohort consisted of 233 patients, of which 76 (32.6%) received SOC, 43 (18.5%) were optimized, and 114 (49.0%) received supportive care or hospice referral. Among the optimized patients, 69.8% were deemed fit for SOC upon re-evaluation following their respective optimization services. The Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS) score was implemented in 2019 (n = 90). Patients receiving supportive/hospice care only had an average score of 5.8, while the averages for those in the optimization and SOC groups were 4.6 and 4.1, respectively (p ≤0.001). Patients receiving SOC had the longest average survival of 2.71 years compared to the optimization (2.30 years) and supportive care groups (0.93 years) (p ≤0.001). For all patients that underwent surgical interventions post-operatively, 23 patients (85%) were discharged home and four (15%) were discharged to a rehabilitation facility.

DISCUSSION

The present study demonstrates the profound impact that the complexities in health status and frailty among older individuals can have during cancer management. The Geriatric Oncology Program at BWMC maximized treatment outcomes for older adults through the provision of SOC therapies and optimization services, while also minimizing unnecessary interventions on an individual patient-centric level.

Impact of Modified Frailty Index on Readmissions Following Surgery for NSCLC

BACKGROUND

 Analyzing the risk factors that predict readmissions can potentially lead to more individualized patient care. The 11-factor modified frailty index is a valuable tool for predicting postoperative outcomes following surgery. The objective of this study is to determine whether the frailty index can effectively predict readmissions within 90 days after lung resection surgery in cancer patients within a single health care institution.

METHODS

 Patients who underwent elective pulmonary resection for nonsmall cell lung cancer (NSCLC) between January 2012 and December 2020 were selected from the hospital's database. Patients who were readmitted after surgery were compared to those who were not, based on their data. Propensity score matching was employed to enhance sample homogeneity, and further analyses were conducted on this newly balanced sample.

RESULTS

 A total of 439 patients, with an age range of 68 to 77 and a mean age of 72, were identified. Among them, 55 patients (12.5%) experienced unplanned readmissions within 90 days, with an average hospital stay of 29.4 days. Respiratory failure, pneumonia, and cardiac issues accounted for approximately 67% of these readmissions. After propensity score matching, it was evident that frail patients had a significantly higher risk of readmission. Additionally, frail patients had a higher incidence of postoperative complications and exhibited poorer survival outcomes with statistical significance.

CONCLUSION

 The 11-item modified frailty index is a reliable predictor of readmissions following pulmonary resection in NSCLC patients. Furthermore, it is significantly associated with both survival and postoperative complications.

Consensus on managing open ankle fractures in the frail patient

Aims

Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest.

Methods

A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS).

Results

In the first stage, there were 36 respondents to the survey, with over 70% stating their unit treats more than 20 such cases per year. There was a 50:50 split regarding if the timing of surgery should be within 36 hours, as per the hip fracture guidelines, or 72 hours, as per the open fracture guidelines. Overall, 75% would attempt primary wound closure and 25% would utilize a local flap. There was no orthopaedic agreement on fixation, and 75% would permit weightbearing immediately. In the second stage, performed at the BLRS meeting, experts discussed the survey results and agreed upon a consensus for the management of open elderly ankle fractures.

Conclusion

A mutually agreed consensus from the expert panel was reached to enable the best practice for the management of patients with frailty with an open ankle fracture: 1) all units managing lower limb fragility fractures should do so through a cohorted multidisciplinary pathway. This pathway should follow the standards laid down in the "care of the older or frail orthopaedic trauma patient" British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guideline. These patients have low bone density, and we should recommend full falls and bone health assessment; 2) all open lower limb fragility fractures should be treated in a single stage within 24 hours of injury if possible; 3) all patients with fragility fractures of the lower limb should be considered for mobilisation on the day following surgery; 4) all patients with lower limb open fragility fractures should be considered for tissue sparing, with judicious debridement as a default; 5) all patients with open lower limb fragility fractures should be managed by a consultant plastic surgeon with primary closure wherever possible; and 6) the method of fixation must allow for immediate unrestricted weightbearing.

Correlation of preoperative frailty with postoperative delirium and one-year mortality in Chinese geriatric patients undergoing noncardiac surgery: Study protocol for a prospective observational cohort study

BACKGROUND

To Frailty is associated with postoperative delirium (POD) but is rarely assessed in patients undergoing noncardiac surgery. In this study, the correlation between preoperative frailty and POD, one-year mortality will be investigated in noncardiac Chinese geriatric surgery patients.

METHODS

This study is a prospective, observational, cohort study conducted at a single center with Chinese geriatric patients. Patients who undergo noncardiac surgery and are older than 70 years will be included. A total of 536 noncardiac surgery patients will be recruited from the First Affiliated Hospital of Shandong First Medical University for this study. The Barthel Index (BI) rating will be used to assess the patient's ability to carry out everyday activities on the 1st preoperative day. The modified frailty index (mFI) will be used to assess frailty. Patients in the nonfrailty group will have an mFI < 0.21, and patients in the frailty group will have an mFI ≥ 0.21. The primary outcome is the incidence of POD. Three-Minute Diagnostic Interview for CAM-defined Delirium (3D-CAM) will be conducted twice daily during the 1st-7th postoperative days, or just before discharge. The secondary outcomes will include one-year mortality, in-hospital cardiopulmonary events, infections, acute renal injury, and cerebrovascular events.

DISCUSSION

This study will clarify the correlation of preoperative frailty with POD and one-year all-cause mortality in Chinese geriatric patients undergoing noncardiac surgery. Can preoperative frailty predict POD or one-year mortality? In the face of China's serious aging social problems, this result may have important clinical value for the surgical treatment of geriatric patients.

TRIAL REGISTRATION

This protocol has been registered with ClinicalTrials. Gov on 12 January 2022 (https://clinicaltrials.gov/ct2/show/NCT05189678).

Modified Frailty Index Predicts Postoperative Complications Following Parastomal Hernia Repair

BACKGROUND

The 5-factor frailty index (5-mFI), validated frailty index with Spearmen rho correlation of .95 and C statistic >.7 for predicting postoperative complications, can be preoperatively used to stratify patients prior to parastomal hernia repairs.

METHODS

Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database identified patients from 2015 to 2020. 5-mFI scores were calculated by adding one point for each comorbidity present: diabetes mellitus, congestive heart failure (CHF), hypertension requiring medication, severe chronic obstructive pulmonary disease (COPD), non-independent functional status. Primary endpoint was 30-day overall complications; secondary endpoints were 30-day readmission, reoperation, and discharge to care facility.

RESULTS

2924 (52.2% female) patients underwent elective parastomal hernia repair. Univariate analysis showed 5-mFI > 2 had higher rates of overall (P = .008), pulmonary (P = .002), cardiovascular (P = .003)), hematologic (P = .003), and renal (P = .002) complications and higher rates of readmission (P = .009), reoperation (P = .001), discharge to care facility (P < .001), and death (P < .001). Multivariate analysis identified a 5-mFI of 2 or more as an independent risk factor for overall complications [OR: 1.40, 1.03-1.78; P = .032], pulmonary complications [2.97, 1.63-5.39; P < .001], hematological complications [1.60, 1.03-2.47; P = .035], renal complications [2.04, 1.19-3.46; P = .009], readmission [1.54, 1.19-1.99; P < .001], and discharge to facility [2.50, 1.66-3.77; P < .001]. Reoperation was not signification on multivariate analysis.

CONCLUSIONS

Parastomal hernia repair patients with 5-mFI score of >2 had higher risk of renal, cardiovascular, pulmonary, and hematologic complications, readmissions, longer hospitalization, discharge to care facility, and mortality, and can be useful during preoperative risk stratification.

The Impact of Frailty on Outcomes of Proximal Aortic Aneurysm Surgery: A Nationwide Analysis

(1) Background: This study examines frailty's impact on proximal aortic surgery outcomes. (2) Methods: All patients with a thoracic aortic aneurysm who underwent aortic root, ascending aorta, or arch surgery from the 2016-2017 National Inpatient Sample were included. Frailty was defined by the Adjusted Clinical Groups Frailty Indicator. Outcomes of interest included in-hospital mortality and a composite of death, stroke, acute kidney injury (AKI), and major bleeding (MACE). (3) Results: Among 5745 patients, 405 (7.0%) met frailty criteria. Frail patients were older, with higher rates of chronic pulmonary disease, diabetes, and chronic kidney disease. There was no difference in in-hospital death (4.9% vs. 2.4%, p = 0.169); however, the frail group exhibited higher rates of stroke and AKI. Frail patients had a longer length of stay (17 vs. 8 days), and higher rates of non-home discharge (74.1% vs. 54.3%) than non-frail patients (both p < 0.001). Sensitivity analysis confirmed increased morbidity and mortality in frail individuals. After adjusting for patient comorbidities and hospital characteristics, frailty independently predicted MACE (OR 4.29 [1.88-9.78], p = 0.001), while age alone did not (OR 1.00 [0.99-1.02], p = 0.568). Urban teaching center status predicted a lower risk of MACE (OR 0.27 [0.08-0.94], p = 0.039). (4) Conclusions: Frailty is associated with increased morbidity in proximal aortic surgery and is a more significant predictor of mortality than age. Coordinated treatment in urban institutions may enhance outcomes for this high-risk group.

Associations of physical frailty with incidence and mortality of overall and site-specific cancers: A prospective cohort study from UK biobank

OBJECTIVE

Evidence regarding the role of physical frailty in cancer-related outcomes is limited. We aimed to examine the association of frailty with cancer incidence and mortality risk.

METHODS

This prospective study included 348,144 participants free of cancer at baseline from the UK Biobank. Frailty phenotypes (non-frail, pre-frail, and frail) were constructed from 5 components: weight loss, exhaustion, low physical activity, slow gait speed, and low grip strength. The outcome was incidence and mortality of overall and cite-specific cancers. Cox proportional hazard regression was used to estimate the association of frailty phenotypes with cancer incidence and mortality risk.

RESULTS

A total of 43,304 incident cancer cases and 10,152 cancer deaths were documented during a median of 12.0 years of follow-up. For overall cancer, compared with non-frailty, the incidence risk increased by 4% for pre-frailty and 11% for frailty, and the mortality risk increased by 11% for pre-frailty and 39% for frailty. Frailty phenotypes were also dose-dependently associated with a higher risk of incidence and mortality of some site-specific cancers (including liver and lung), with significant sex differences. We observed a synergetic association of frailty phenotypes and smoking with overall cancer incidence and mortality risk.

CONCLUSIONS

Frailty phenotypes contributed significantly to a higher risk of overall and some site-specific cancers incidence and mortality in a stepwise manner or within individual categories. Future studies are warranted to emphasize the identification, management and prevention of frailty in the whole population and complements of lifestyle-targeted interventions such as quitting smoking.

Factors Associated with the Rehabilitation of the Older Adult Burn Patient

The number of older people is increasing and as a result so will the number of older adult patients who present with a burn injury. There are distinct differences between older and younger burn patients, particularly with respect to skin anatomy and physiology and frailty. These are 2 important factors that influence the rehabilitation efforts with respect to older adult burn patients. There has been minimal work done studying the specific rehabilitation of older adult burn patients. More work is needed to fully understand the rehabilitation needs of older adult burn patients.

Influence of preoperative frailty on quality of life after cardiac surgery: A systematic review and meta-analysis

BACKGROUND

Frailty has emerged as an important prognostic marker of increased mortality after cardiac surgery, but its association with quality of life (QoL) and patient-centered outcomes is not fully understood. We sought to evaluate the association between frailty and such outcomes in older patients undergoing cardiac surgery.

METHODS

This systematic review included studies evaluating the effect of preoperative frailty on QoL outcomes after cardiac surgery amongst patients 65 years and older. The primary outcome was patient's perceived change in QoL following cardiac surgery. Secondary outcomes included residing in a long-term care facility for 1 year, readmission in the year following the intervention, and discharge destination. Screening, inclusion, data extraction, and quality assessment were performed independently by two reviewers. Meta-analyses based on the random-effects model were conducted. The evidential quality of findings was assessed with the GRADE profiler.

RESULTS

After the identification of 3105 studies, 10 observational studies were included (1580 patients) in the analysis. Two studies reported on the change in QoL following cardiac surgery, which was higher for patients with frailty than for patients without. Preoperative frailty was associated with both hospital readmission (pooled odds ratio [OR] 1.48 [0.80-2.74], low GRADE level) as well as non-home discharge (pooled OR 3.02 [1.57-5.82], moderate GRADE level).

CONCLUSION

While evidence in this field is limited by heterogeneity of frailty assessment and non-randomized data, we demonstrated that baseline frailty may possibly be associated with improved QoL, but with increased readmission as well as discharge to a non-home destination following cardiac surgery. These patient-centered outcomes are important factors when considering interventional options for older patients.

The psoas muscle density as a predictor of postoperative complications in elderly patients undergoing rectal cancer resection

Background

Muscle depletion that impairs normal physiological function in elderly patients leads to poor prognosis. This study aimed to evaluate the association between total abdominal muscle area (TAMA), total psoas area (TPA), psoas muscle density (PMD), and short-term postoperative complications in elderly patients with rectal cancer.

Methods

All elderly patients underwent rectal cancer resection with perioperative abdominal computed tomography (CT). Complications were assessed according to the Clavien-Dindo classification. Severe complications were defined as grade III-V following the Clavien-Dindo classification. Univariate and multivariate analyses were performed to evaluate risk factors of short-term severe postoperative complications.

Results

The cohort consisted of 191 patients with a mean age of 73.60 ± 8.81 years. Among them, 138 (72.25%) patients had Clavien-Dindo 0- II, 53 (27.75%) patients had severe postoperative complications (Clavien-Dindo III-V), and 1(0.52%) patient died within 30 days of surgery. PMD was significantly higher in the Clavien-Dindo 0-II cohort compared to the Clavien-Dindo III-V cohort (p=0.004). Nevertheless, TAMA and TPA failed to exhibit significant differences. Moreover, the multivariate regression analysis implied that advanced age [OR 1.07 95%CI (1.02-1.13) p=0.013], male [OR 5.03 95%CI (1.76-14.41) p=0.003], high charlson comorbidity index (CCI) score [OR 3.60 95%CI (1.44-9.00) p=0.006], and low PMD [OR 0.94 95%CI (0.88-0.99) p=0.04] were independent risk factors of Clavien-Dindo III-V.

Conclusion

Preoperative assessment of the PMD on CT can be a simple and practical method for identifying elderly patients with rectal cancer at risk for severe postoperative complications.

Impact of Prehabilitation on Postoperative Mortality and the Need for Non-Home Discharge in High-Risk Surgical Patients

BACKGROUND

The preoperative period is an important target for interventions (eg Surgical Prehabilitation and Readiness [SPAR]) that can improve postoperative outcomes for older patients with comorbidities.

STUDY DESIGN

To determine whether a preoperative multidisciplinary prehabilitation program (SPAR) reduces postoperative 30-day mortality and the need for non-home discharge in high-risk surgical patients, surgical patients enrolled in a prehabilitation program targeting physical activity, pulmonary function, nutrition, and mindfulness were compared with historical control patients from 1 institution's American College of Surgeons (ACS) NSQIP database. SPAR patients were propensity score-matched 1:3 to pre-SPAR NSQIP patients, and their outcomes were compared. The ACS NSQIP Surgical Risk Calculator was used to compare observed-to-expected ratios for postoperative outcomes.

RESULTS

A total of 246 patients were enrolled in SPAR. A 6-month compliance audit revealed that overall patient adherence to the SPAR program was 89%. At the time of analysis, 118 SPAR patients underwent surgery with 30 days of follow-up. Compared with pre-SPAR NSQIP patients (n = 4,028), SPAR patients were significantly older with worse functional status and more comorbidities. Compared with propensity score-matched pre-SPAR NSQIP patients, SPAR patients had significantly decreased 30-day mortality (0% vs 4.1%, p = 0.036) and decreased need for discharge to postacute care facilities (6.5% vs 15.9%, p = 0.014). Similarly, SPAR patients exhibited decreased observed 30-day mortality (observed-to-expected ratio 0.41) and need for discharge to a facility (observed-to-expected ratio 0.56) compared with their expected outcomes using the ACS NSQIP Surgical Risk Calculator.

CONCLUSIONS

The SPAR program is safe and feasible and may reduce postoperative mortality and the need for discharge to postacute care facilities in high-risk surgical patients.

Robotic Bariatric Surgery in Older Adults, Is It Safer Than the Laparoscopic Approach? A 7-Year Analysis of Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Database

BACKGROUND

Utilization of the robotic platform in bariatric surgery has increased over the past several years. The population of older adults who benefit from bariatric surgery is also growing. This study evaluated the safety of robotic-assisted bariatric surgery in older adults using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Database.

METHODS

Adults who underwent gastric bypass or sleeve gastrectomy and were ≥ 65 years old between the years 2015 and 2021 were included. The 30-day outcomes were assessed and stratified based on Clavien-Dindo (CD) classification of III-V. Univariable and multivariable logistic regressions were performed to identify predictors of CD ≥ III complications.

RESULTS

A total of 62,973 bariatric surgery patients were included. Most of the patients (90%) underwent laparoscopic surgery, and the remainder (10%) underwent robotic surgery. Robotic sleeve gastrectomy (R-SG) was associated with lower odds of developing CD ≥ III complications compared to three other procedures (adjusted odds ratio (aOR), 0.741; confidence interval (CI), 0.584-0.941; p 0.014).

CONCLUSIONS

Bariatric surgery using a robotic approach is considered safe for older patients. Robotic sleeve gastrectomy (R-SG) has the lowest morbidity and mortality rates compared to laparoscopic sleeve gastrectomy (L-SG), laparoscopic Roux-en-Y gastric bypass (L-RYGB), and robotic Roux-en-Y gastric bypass (R-RYGB). The findings of this study can help surgeons and their elderly patients to make informed decisions regarding the safety of different bariatric surgical approaches.

Sarcopenia, frailty, and elective surgery outcomes in the elderly: an observational study with 125 patients (the SAFESOE study)

Background

Sarcopenia is a syndrome characterized by loss of muscle mass, strength and function. Frailty, a state of vulnerability with diminished reserves. The measurement of perioperative risk does not include the assessment of these variables, as little is known about how these conditions impact each other.

Methods

Observational study with a cross-sectional and a prospective cohort component. Elderly people over 60 years of age, able to walk and to independently perform activities of daily living were consecutively recruited in the preoperative period of non-emergency surgical procedures. Frailty was measured by the modified frailty index (mFI-11). Sarcopenia was measured by: (1) thickness and echogenicity on ultrasound; (2) handgrip strength on dynamometry and (3) gait speed. Data obtained from eight muscle groups were submitted to Principal Component Analysis. Postoperative complications were measured using the Clavien-Dindo scale. Follow-up was performed for 1 year to record readmissions and deaths.

Results

Between February and May 2019, 125 elderly people were recruited, median age of 71 years (IQR 65-77), 12% of whom were frail. Frailty was associated with older age, use of multiple medicines, presence of multimorbidity and greater surgical risk according to the American Society of Anesthesiologists (ASA) scale, in addition to lower gait speeds and lower handgrip strength. Frailty was also independently associated with smaller measurements of muscle thickness but not with echogenicity, and with longer hospital and Intensive care unit (ICU) stays. Prevalence of sarcopenia was 14% when considering at least two criteria: low walking speed and low handgrip strength. For muscle thickness, lower values were associated with female gender, older age, frailty, lower gait speeds and lower muscle strength, higher proportion of postoperative complications and higher occurrence of death. For echogenicity, higher values were related to the same factors as those of lower muscle thickness, except for postoperative complications. Lower gait speeds and lower handgrip strength were both associated with higher proportions of postoperative complications, and longer hospital stays. A higher mortality rate was observed in those with lower gait speeds.

Conclusion

Sarcopenia was associated with frailty in all its domains. Unfavorable surgical outcomes were also associated with these two conditions.

Substitution of self-reported measures for objectively assessed grip strength and slow walk in the Physical Frailty Phenotype: ramifications for validity

BACKGROUND

Frailty assessment promises to identify older adults at risk for adverse consequences following stressors and target interventions to improve health outcomes. The Physical Frailty Phenotype (PFP) is a widely-studied, well validated assessment but incorporates performance-based slow walk and grip strength criteria that challenge its use in some clinical settings. Variants replacing performance-based elements with self-reported proxies have been proposed. Our study evaluated whether commonly available disability self-reports could be substituted for the performance-based criteria in the PFP while still identifying as "frail" the same subpopulations of individuals.

METHODS

Parallel analyses were conducted in 3393 female and 2495 male Cardiovascular Health Study, Round 2 participants assessed in 1989-90. Candidate self-reported proxies for the phenotype's "slowness" and "weakness" criteria were evaluated for comparable prevalence and agreement by mode of measurement. For best-performing candidates: Frailty status (3 + positive criteria out of 5) was compared for prevalence and agreement between the PFP and mostly self-reported versions. Personal characteristics were compared between those adjudicated as frail by (a) only a self-reported version; (b) only the PFP; (c) both, using bivariable analyses and multinomial logistic regression.

RESULTS

Self-reported difficulty walking ½ mile was selected as a proxy for the phenotype's slowness criterion. Two self-reported weakness proxies were examined: difficulty transferring from a bed or chair or gripping with hands, and difficulty as just defined or in lifting a 10-pound bag. Prevalences matched to within 4% between self-reported and performance-based criteria in the whole sample, but in all cases the self-reported prevalence for women exceeded that for men by 11% or more. Cross-modal agreement was moderate, with by-criterion and frailty-wide Kappa statistics of 0.55-0.60 in all cases. Frail subgroups (a), (b), (c) were independently discriminated (p < 0.05) by race, BMI, and depression in women; by age in men; and by self-reported health for both.

CONCLUSIONS

Commonly used self-reported disability items cannot be assumed to stand in for performance-based criteria in the PFP. We found subpopulations identified as frail by resultant phenotypes versus the original phenotype to systematically differ. Work to develop self-reported proxies that more closely replicate their objective phenotypic counterparts than standard disability self-reports is needed.

Assessing and managing frailty in emergency laparotomy: a WSES position paper

Many countries are facing an aging population. As people live longer, surgeons face the prospect of operating on increasingly older patients. Traditional teaching is that with older age, these patients face an increased risk of mortality and morbidity, even to a level deemed too prohibitive for surgery. However, this is not always true. An active 90-year-old patient can be much fitter than an overweight, sedentary 65-year-old patient with comorbidities. Recent literature shows that frailty-an age-related cumulative decline in multiple physiological systems, is therefore a better predictor of mortality and morbidity than chronological age alone. Despite recognition of frailty as an important tool in identifying vulnerable surgical patients, many surgeons still shun objective tools. The aim of this position paper was to perform a review of the existing literature and to provide recommendations on emergency laparotomy and in frail patients. This position paper was reviewed by an international expert panel composed of 37 experts who were asked to critically revise the manuscript and position statements. The position paper was conducted according to the WSES methodology. We shall present the derived statements upon which a consensus was reached, specifying the quality of the supporting evidence and suggesting future research directions.

Frailty Assessment and Prehabilitation as Part of a PeRioperative Evaluation and Planning (PREP) Program for Patients Undergoing Colorectal Surgery

Frailty assessment and prehabilitation can be incrementally implemented in a multidisciplinary, multiphase pathway to improve patient care. To start, modifications can be made to a surgeon's practice with existing resources while adapting standard pathways for frail patients. Frailty screening can identify patients in need of additional assessment and optimization. Personalized utilization of frailty data for optimization through prehabilitation can improve postoperative outcomes and identify patients who would benefit from adapted care. Additional utilization of the multidisciplinary team can lead to improved outcomes and a strong business case to add additional members of the team.

Management of Older Patients with Head and Neck Cancer: A Comprehensive Review

The projected increase in life expectancy over the next few decades is expected to result in a rise in age-related diseases, including cancer. Head and neck cancer (HNC) is a worldwide health problem with high rates of morbidity and mortality. In this report, we have critically reviewed the literature reporting the management of older patients with HNC. Older adults are more prone to complications and toxicities secondary to HNC treatment, especially those patients who are frail or have comorbidities. Thus, this population should be screened prior to treatment for such predispositions to maximize medical management of comorbidities. Chronologic age itself is not a reason for choosing less intensive treatment for older HNC patients. Whenever possible, also older patients should be treated according to the best standard of care, as nonstandard approaches may result in increased treatment failure rates and mortality. The treatment plan is best established by a multidisciplinary tumor board with shared decision-making with patients and family. Treatment modifications should be considered for those patients who have severe comorbidities, evidence of frailty (low performance status), or low performance status or those who refuse the recommendations of the tumor board.

Comparison of Frailty Criteria, Cognitive Function, Depressive and Insomnia Symptoms in Men with Localized and Advanced Prostate Cancer under Androgen Deprivation Therapy

BACKGROUND

Prostate cancer (PCa) is considered one of the most important medical problems in the male population, with a very high incidence after the age of 65. Frailty represents one of the most critical issues facing healthcare due to its inherent relationship with poor healthcare outcomes. The physical phenotype of frailty syndrome based on Fried criteria has been associated with poor outcomes, morbidity, and premature mortality. To date, there are few studies that have analyzed frailty syndrome in patients with localized and advanced (mPCa) disease under androgen-deprivation therapy.

OBJECTIVE

Our goal was to assess whether there are differences in frailty criteria between mPCa and localized PCa. We also evaluated the role of other geriatric variables such as depressive and insomnia symptoms, which are frequently reported in cancer patients.

METHODS

In this cross-sectional study, frailty syndrome was evaluated in both groups, as well as its possible relationship with cognitive functions, depressive and insomnia symptoms, and other clinical variables related to PCa and its treatment. Frailty was defined on Fried's criteria: low lean mass, weakness, self-reported exhaustion, low activity level, and slow walking speed; prefrailty was defined as having one or two of those criteria and frailty as having three or more, depressive symptoms were defined by the Yesavage scale, cognitive functions with the Mini-Mental examination test, and insomnia symptoms by the Athens scale and self-reported health status.

RESULTS

The prevalence of prefrailty/frailty was slightly higher in mPCa compared to localized PCa (81.5% versus 72.3%, respectively), however by analyzing each of the frailty criteria, two of them were significantly reduced in mPCa compared to localized PCa patients, e.g., gait speed (p = 0.001) and muscle strength (p = 0.04). The reduced gait speed and muscle strength in mPCa were not due to the increased age in mPCa group, or to an increase in comorbidities or shorter time under androgen-deprivation therapy. The symptoms of insomnia were significantly higher in mPCa patients compared to those with localized PCa (p < 0.05) whereas cognitive functions or depressive symptoms were not significantly different between the two groups.

CONCLUSION

Patients with mPCa under androgen-deprivation therapy display higher alterations in gait speed and muscular strength and insomnia symptoms, thus interventions should be aimed to reduce these alterations in order to limit adverse outcomes related to them and to improve quality of life in these patients.

A patient with heart failure, who is frail: How does this affect therapeutic decisions?

Patients with heart failure (HF) are heterogeneous, not only related to comorbidities but also in the presentation of frailty syndrome. Frailty syndrome also affects patients with HF across the lifespan. Frailty in patients with HF has a significant impact on clinical features, diagnosis, management, adverse medical outcomes and costs. In everyday clinical practice, frail patients with HF require an individualized approach, often imposing the need to modify therapeutic decisions. The aim of this review is to illustrate how frailty and multimorbidity in HF can affect therapeutic decisions. The scientific evidence underlying this publication was obtained from an analysis of papers indexed in the PubMed database. The search was limited to articles published between 1990 and July 2022. The search was limited to full-text papers published in English. The database was searched for relevant MeSH phrases and their combinations and keywords including: "elderly, frail"; "frailty, elderly"; "frail older adults"; "frailty, older adults"; "adult, frail older"; "frailty, heart failure"; "frailty, multimorbidity"; "multimorbidity, heart failure"; "multimorbidity, elderly"; "older adults, cardiovascular diseases". In therapeutic decisions regarding patients with HF, additionally burdened with multimorbidity and frailty, it becomes necessary to individualize the approach in relation to optimization and treatment of coexisting diseases, frailty assessment, pharmacological and non-pharmacological treatment and in the implementation of invasive procedures in the form of implantable devices or cardiac surgery.

Frailty as an indicator of postoperative complications following surgical excision of non-melanoma skin cancer on the head and neck

INTRODUCTION

Non-melanoma skin cancer (NMSC) predominantly affects those aged over 90 years, with 85% of lesions arising on the head and neck, where surgical excision remains the treatment of choice. Frailty is a measure of physiologic age and can be used as a predictor of adverse treatment outcomes. The aim of this study was to determine if the Rockwood Frailty Index is predictive of complications following excision of NMSC.

METHODS

Data were collected prospectively for patients who underwent an excision of a suspected NMSC from the head or neck across a two-month period. Details of the patient, lesion and procedure were recorded alongside ASA grade and Rockwood's Frailty score. Postoperative complications were recorded four weeks later.

RESULTS

There was a total of 125 patients: 74 (60%) male, 51 (40%) female; mean age was 78 (±9.8) years. Of the excised sites, 61% were closed primarily, 26% with a full thickness skin graft (FTSG), 13% with a local flap. Frailty ranged from 1 to 7 (median = 4). ASA ranged from 1 to 4 (median = 3). A total of 21 (17%) patients reported postoperative complications. Within this group, the median frailty and ASA grades were 5 and 3. Both frailty and ASA were positively significantly associated with age (p ≤ 0.001). There was no significant difference between the frailty or ASA grades of patients that experienced complications and those who did not. Patients who had a FTSG were significantly more likely to experience complications (p ≤ 0.05).

CONCLUSIONS

Frailty is not predictive of postoperative complications following excision of NMSC on the head and neck. Postoperative complications are significantly more associated with FTSG.

Geriatric assessment and treatment decision-making in surgical oncology

PURPOSE OF REVIEW

Present an approach for surgical decision-making in cancer that incorporates geriatric assessment by building upon the common categories of tumor, technical, and patient factors to enable dual assessment of disease and geriatric factors.

RECENT FINDINGS

Conventional preoperative assessment is insufficient for older adults missing important modifiable deficits, and inaccurately estimating treatment intolerance, complications, functional impairment and disability, and death. Including geriatric-focused assessment into routine perioperative care facilitates improved communications between clinicians and patients and among interdisciplinary teams. In addition, it facilitates the detection of geriatric-specific deficits that are amenable to treatment. We propose a framework for embedding geriatric assessment into surgical oncology practice to allow more accurate risk stratification, identify and manage geriatric deficits, support decision-making, and plan proactively for both cancer-directed and non-cancer-directed therapies. This patient-centered approach can reduce adverse outcomes such as functional decline, delirium, prolonged hospitalization, discharge to long-term care, immediate postoperative complications, and death.

SUMMARY

Geriatric assessment and management has substantial benefits over conventional preoperative assessment alone. This article highlights these advantages and outlines a feasible strategy to incorporate both disease-based and geriatric-specific assessment and treatment when caring for older surgical patients with cancer.

Analysis of Frailty Syndrome in Men with Metastatic Prostate Cancer: A Scoping Review

Most patients with metastatic prostate cancer (mPCa) are older. In addition, current geriatric oncology guidelines suggest that all cancer patients aged over 70 years should undergo a comprehensive geriatric assessment (CGA), with the identification of frailty syndrome being crucial for clinical decisions. Frailty can be associated with lower quality of life (QoL) and interfere with the feasibility or side effects of oncology treatments.

METHODS

We performed a systematic literature search to evaluate frailty syndrome and associated alterations related to CGA impairment by searching in different academic databases (PubMed, Embase, and Scopus). The identified articles were reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

Of the 165 articles consulted, 7 met our inclusion criteria. Analysis of data related to frailty syndrome in patients with mPCa showed a prevalence between 30-70% depending on the tool used. Additionally, frailty was associated with other CGA assessments and QoL evaluation outcomes. In general terms, CGA scores for patients with mPCa were lower than those for patients without metastasis. Furthermore, functional QoL appeared to be worse for patients with metastasis, and global QoL (burden) was more strongly associated with frailty.

CONCLUSION

Frailty syndrome was related to a poorer QoL in patients with mPCa and its evaluation should be considered in clinical decision-making and when choosing the most appropriate active treatment, if any, to increase survival.

Even minor alteration of plasma creatinine after open abdominal surgery is associated with 30-day mortality: A single-centre cohort study

PURPOSE

Postoperative acute kidney injury is common and associated with increased length of hospital stay, costs and mortality. The impact from postoperative subclinical changes in plasma concentration of creatinine (p-creatinine) on postoperative mortality has received less attention. In this study, the association between the postoperative change of p-creatinine and all-cause mortality was investigated.

METHODS

A single-centre register-based, retrospective study was conducted including patients ≥60 years undergoing open abdominal surgery from 2000 to 2013. Postoperative p-creatinine change was analysed for association with 30-day mortality following adjustment for age, gender, surgical setting and surgical procedure. Main findings A total of 3,460 patients were included in the study of whom 67.6% underwent emergency surgery. The 30-day mortality rate was 18.3%, and a given 10μmol/L daily postoperative increase in p-creatinine was associated with an increased mortality risk with an odds ratio (OR) of 2.67 (95% CI; 2.28-3.14, P<0.001). In patients undergoing emergency surgery, a daily 10μmol/L increase in p-creatinine increased the risk for a fatal outcome a 2.39 OR (CI 95%; 2.05-2.78), P<0.001). In patients undergoing elective surgery, a similar increase in p-creatinine increased risk of postoperative death with a 28.85 OR (CI 95%; 10.25-81.19).

CONCLUSION

Even a minor postoperative p-creatinine increase following open abdominal surgery below the criteria for acute kidney injury was associated with increased 30-day mortality in patients aged 60 years or above.

Preoperative frailty screening, assessment and management

PURPOSE OF REVIEW

To highlight the importance of frailty assessment in thoracic surgery patients.

RECENT FINDINGS

Frailty results from an accelerated loss of functional reserve associated with ageing and leads to increased vulnerability following surgery. It is a complex and multidimensional syndrome involving physiological and psychosocial systems. Frailty is a separate entity from comorbidities and disabilities. Frailty is associated with an increased risk of complications and a higher mortality rate after thoracic surgery. Patients can easily be screened for frailty and frail patients can benefit from further assessment of all areas of frailty secondarily. Prehabilitation and rehabilitation can help limit frailty-related complications after thoracic surgery.

SUMMARY

Frailty should be part of the routine preoperative evaluation for thoracic surgery. Frailty must be considered in assessing eligibility for surgery and in planning prehabilitation and rehabilitation if necessary.

Frailty and Acute Postoperative Urinary Retention in Older Women Undergoing Pelvic Organ Prolapse Surgery

IMPORTANCE

Acute postoperative urinary retention (POUR) is common after pelvic reconstructive surgery, occurring in 15-45% of women. There is a paucity of data on the relationship between frailty and POUR after prolapse surgery.

OBJECTIVE

This study aimed to examine the association between frailty and POUR in older women who underwent pelvic organ prolapse surgery.

STUDY DESIGN

This secondary analysis of a prospective study of postoperative delirium enrolled women 60 years and older undergoing prolapse surgery. The Fried Frailty Index was used to assess frailty before surgery. Acute POUR was defined as failure to pass a retrograde voiding trial at hospital discharge with postvoid residual volume of greater than 100 mL.

RESULTS

Analyses included 165 women, with a mean ± SD age of 72.5 ± 6.1 years and a body mass index of 28.0 ± 4.4 kg/m2. There were 49 laparoscopic/robotic apical suspension procedures (29.7%), 60 vaginal obliterative procedures (36.4%), 47 vaginal apical suspension procedures (28.5%), and 9 isolated anterior and/or posterior colporrhaphies (5.5%), of which 9 had a concomitant incontinence procedure. Seventy-eight women (47.3%) experienced acute POUR. Thirty-one (18.8%) met the criteria for "not frail," 115 (88.5%) were "prefrail," and 19 (11.5%) were "frail." Neither frailty status nor score was associated with POUR. In an analysis of individual Fried Frailty Index components, self-reported unintentional weight loss was significantly associated with POUR (odds ratio, 4.6; 95% confidence interval, 1.23-17.15). This remained significant on multivariable logistic regression (adjusted odds ratio, 4.06; 95% confidence interval, 1.01-16.39).

CONCLUSIONS

Frailty was not associated with POUR in older women undergoing prolapse surgery. The observed association between POUR and unintended weight loss before surgery warrants further investigation.

Meta-Analysis of Simultaneous versus Staged Decompression of Stenotic Regions in Patients with Tandem Spinal Stenosis

BACKGROUND

Tandem spinal stenosis (TSS) refers to simultaneous spinal canal stenosis of noncontiguous regions. There is no consensus in the surgical strategies for patients with symptomatic TSS because of the confusing clinical manifestations. This meta-analysis aimed to compare the outcomes of 1-stage and 2-stage decompression of all stenotic regions (cervical and lumbar/thoracic segments) in patients with TSS.

METHODS

A systematic review was conducted, and a comprehensive literature search with the Japanese Orthopedic Association score, was carried out using MEDLINE, Web of Science, and PubMed databases from inception to September 13, 2022. Observational studies reporting the outcomes after 1-stage or 2-stage decompression of all symptomatic regions were included. Possible heterogeneity among studies was assessed by the Higgins I2 test, and heterogeneity was statistically investigated using the Q statistic.

RESULTS

Thirteen retrospective observational studies were included in this meta-analysis. Meta-analysis showed that there was no significant difference in the Japanese Orthopedic Association score improvement in patients with TSS involving either the cervical-thoracic or cervical-lumbar segments. Regarding the surgical parameters and complications, 1-stage decompression showed comparable operation time, blood loss, and major complications to 2-stage decompression in patients with cervical and lumbar TSS. In patients with cervical and thoracic TSS, 1-stage decompression had significant advantages compared with 2-stage decompression in operation time, blood loss, and major complications.

CONCLUSIONS

For patients with cervical and lumbar TSS, 2-stage decompression showed slight advantages in clinical outcome without exposing patients to unnecessary surgical risks. For patients with cervical and thoracic TSS, 1-stage decompression showed comparable clinical outcome, although with better operative parameters and lower complication rate than in simultaneous decompression.

Modified Frailty Index Does Not Provide Additional Value in Predicting Outcomes in Patients Undergoing Elective Transforaminal Lumbar Interbody Fusion

OBJECTIVE

To determine the predictive value of the modified Frailty Index (mFI) in evaluating sarcopenia and clinical outcomes in patients undergoing 1-level or 2-level transforaminal lumbar interbody fusion (TLIF).

METHODS

Patients who underwent a 1-level or 2-level TLIF between 2012 and 2020 were retrospectively identified. Frailty was compared among groups using mFI, and sarcopenia was classified by the psoas muscle cross-sectional area. Bivariate statistics compared demographics, comorbidities, and clinical outcomes. A linear regression model was developed using the Charlson Comorbidity Index (CCI) or mFI as independent variables to determine potential predictors for improvement in 1-year patient-reported outcomes.

RESULTS

Of 488 included patients, 60 were severely frail and 60 patients had sarcopenia, but sarcopenia was not associated with patient frailty (P = 0.469). Severely frail patients had worse baseline Oswestry Disability Index (ODI) (P < 0.001), Mental Component Score-12 (P = 0.001), and Physical Component Score-12 (P < 0.001), and worse improvement in ODI (P = 0.037), Physical Component Score-12 (P < 0.001), and visual analog scale (VAS) back (P = 0.007). mFI was an independent predictor of poorer improvement in VAS back and ODI, whereas age + CCI in addition predicted poorer improvement in VAS leg. Patients with higher mFI experienced longer length of stay, less frequent home discharge, and higher rates of complications, but similar readmission and reoperation rates.

CONCLUSIONS

Frailer patients experience poorer improvement in back pain, physical functioning, and disability after TLIF. mFI and the combination of age and CCI comparably predict patient-reported outcomes but do not correlate to baseline sarcopenia. Frailty increased the risk of complications, length of hospital stay, and risk of nonhome discharge.

Frailty as a predictor of delayed initiation of adjuvant chemotherapy in patients with ovarian cancer

OBJECTIVE

This study aimed to identify whether frailty is associated with the time between surgery and the initiation of chemotherapy for patients with ovarian cancer.

METHODS

This retrospective cohort study included patients 18 years or older with stage II to IV ovarian cancer who underwent primary debulking surgery at a tertiary medical center between July 2006 and July 2015. Basic demographics and clinical information were obtained from a departmental database and the electronic medical record. The Modified Frailty Index (mFI) was calculated based on 10 comorbidities and functional status yielding 11 items total. Patients were categorized by a total score: 0-1=no frailty, 2=moderate frailty and 3+=high frailty.

RESULTS

Among 451 patients, 359 had mFI scores of 0-1, 60 had a score of 2, and 32 had scores of 3+. Mean time from surgery to initiation of chemotherapy was 37 days. Mean number of days between surgery and initiation of chemotherapy increased with increasing frailty score: 36 days for the not frail group, 39 days for the moderate frailty group, and 54 days for the high frailty group (p<0.001). Time to initiation of chemotherapy of 42 days or more occurred in 23% of the no frailty group, 28% in the moderate frailty group, and 63% in the high frailty group (p<0.001). Overall survival decreased with increasing frailty scores.

CONCLUSION

High mFI scores lead to a greater delay between surgery and chemotherapy initiation. Being able to predict delays in initiation of chemotherapy may allow oncologists to consider neoadjuvant chemotherapy, pre-habilitation before surgery, and improved preoperative counseling in high-risk patients.

4,300 steps per day prior to surgery are associated with improved outcomes after pancreatectomy

BACKGROUND

Decreased preoperative physical fitness and low physical activity have been associated with preoperative functional reserve and surgical complications. We sought to evaluate daily step count as a measure of physical activity and its relationship with post-pancreatectomy outcomes.

METHODS

Patients undergoing pancreatectomy were given a remote telemonitoring device to measure their preoperative levels of physical activity. Patient activity, demographics, and perioperative outcomes were collected and compared in univariate and multivariate logistic regression analysis.

RESULTS

73 patients were included. 45 (61.6%) patients developed complications, with 17 (23.3%) of those patients developing severe complications. These patients walked 3437.8 (SD 1976.7) average daily steps, compared to 5918.8 (SD 2851.1) in patients without severe complications (p < 0.001). In logistic regression analysis, patients who walked less than 4274.5 steps had significantly higher odds of severe complications (OR = 7.5 (CI 2.1, 26.8), p = 0.002).

CONCLUSION

Average daily steps below 4274.5 before surgery are associated with severe complications after pancreatectomy. Preoperative physical activity levels may represent a modifiable target for prehabilitation protocols.

Proceedings of the 2021 American Burn Association State and Future of Burn Science Meeting

Periodically, the American Burn Association (ABA) has convened a State of the Science meeting on various topics representing multiple disciplines within burn care and research. In 2021 at the request of the ABA President, meeting development was guided by the ABA's Burn Science Advisory Panel (BSAP) and a subgroup of meeting chairs. The goal of the meeting was to produce both an evaluation of the current literature and ongoing studies, and to produce a research agenda and/or define subject matter-relevant next steps to advance the field(s). Members of the BSAP defined the topics to be addressed and subsequently solicited for nominations of expert speakers and topic leaders from the ABA's Research Committee. Current background literature for each topic was compiled by the meeting chairs and the library then enhanced by the invited topic and breakout discussion leaders. The meeting was held in New Orleans, LA on November 2nd and 3rd and was formatted to allow for 12 different topics, each with two subtopics, to be addressed. Topic leaders provided a brief overview of each topic to approximately 100 attendees, followed by expert-lead breakout sessions for each topic that allowed for focused discussion among subject matter experts and interested participants. The breakout and topic group leaders worked with the participants to determine research needs and associated next steps including white papers, reviews and in some cases collaborative grant proposals. Here, summaries from each topic area will be presented to highlight the main foci of discussion and associated conclusions.

Identifying barriers and facilitators to routine preoperative frailty assessment: a qualitative interview study

PURPOSE

Preoperative frailty assessment is recommended by multiple practice guidelines and may improve outcomes, but it is not routinely performed. The barriers and facilitators of routine preoperative frailty assessment have not been formally assessed. Our objective was to perform a theory-guided evaluation of barriers and facilitators to preoperative frailty assessment.

METHODS

This was a research ethics board-approved qualitative study involving physicians who perform preoperative assessment (consultant and resident anesthesiologists and consultant surgeons). Semistructured interviews were conducted by a trained research assistant informed by the Theoretical Domains Framework to identify barriers and facilitators to frailty assessment. Interview transcripts were independently coded by two research assistants to identify specific beliefs relevant to each theoretical domain.

RESULTS

We interviewed 28 clinicians (nine consultant anesthesiologists, nine consultant surgeons, and ten anesthesiology residents). Six domains (Knowledge [100%], Social Influences [96%], Social Professional Role and Identity [96%], Beliefs about Capabilities [93%], Goals [93%], and Intentions [93%]) were identified by > 90% of respondents. The most common barriers identified were prioritization of other aspects of assessment (e.g., cardio/respiratory) and a lack of awareness of evidence and guidelines supporting frailty assessment. The most common facilitators were a high degree of familiarity with frailty, recognition of the importance of frailty assessment, and strong intentions to perform frailty assessment.

CONCLUSION

Barriers and facilitators to preoperative frailty assessment are multidimensional, but generally consistent across different types of perioperative physicians. Knowledge of barriers and facilitators can guide development of evidence-based strategies to increase frailty assessment.

Association Between Frailty and Time Alive and At Home After Cancer Surgery Among Older Adults: A Population-Based Analysis

BACKGROUND

Although frailty is known to impact short-term postoperative outcomes, its long-term impact is unknown. This study examined the association between frailty and remaining alive and at home after cancer surgery among older adults.

METHODS

Adults aged ≥70 years undergoing cancer resection were included in this population-based retrospective cohort study using linked administrative datasets in Ontario, Canada. The probability of remaining alive and at home in the 5 years after cancer resection was evaluated using Kaplan-Meier methods. Extended Cox regression with time-varying effects examined the association between frailty and remaining alive and at home.

RESULTS

Of 82,037 patients, 6,443 (7.9%) had preoperative frailty. With median follow-up of 47 months (interquartile range, 23-81 months), patients with frailty had a significantly lower probability of remaining alive and at home 5 years after cancer surgery compared with those without frailty (39.1% [95% CI, 37.8%-40.4%] vs 62.5% [95% CI, 62.1%-63.9%]). After adjusting for age, sex, rural living, material deprivation, immigration status, cancer type, surgical procedure intensity, year of surgery, and receipt of perioperative therapy, frailty remained associated with increased hazards of not remaining alive and at home. This increase was highest 31 to 90 days after surgery (hazard ratio [HR], 2.00 [95% CI, 1.78-2.24]) and remained significantly elevated beyond 1 year after surgery (HR, 1.56 [95% CI, 1.48-1.64]). This pattern was observed across cancer sites, including those requiring low-intensity surgery (breast and melanoma).

CONCLUSIONS

Preoperative frailty was independently associated with a decreased probability of remaining alive and at home after cancer surgery among older adults. This relationship persisted over time for all cancer types beyond short-term mortality and the initial postoperative period. Frailty assessment may be useful for all candidates for cancer surgery, and these data can be used when counseling, selecting, and preparing patients for surgery.

Frailty and postoperative urinary tract infection

BACKGROUND

Among older adults, postoperative urinary tract infection is associated with significant harms including increased risk of hospital readmission and perioperative mortality. While risk of urinary tract infection is known to increase with age, the independent association between frailty and postoperative urinary tract infection is unknown. In this study we used 2014-2018 data from the U.S. National Surgical Quality Improvement Program (NSQIP) to investigate whether frailty is an independent risk factor for postoperative urinary tract infection, controlling for age and other relevant confounders.

METHODS

Frailty was assessed using the modified Frailty Index. Postoperative urinary tract infection was defined as any symptomatic urinary tract infection (of the kidneys, ureters, bladder, or urethra) developing within 30 days of the operative procedure. To examine associations between frailty and other specific factors and postoperative urinary tract infection, chi squared tests, students t-tests, and logistic regression modelling were used.

RESULTS

Urinary tract infection was identified after 22,356 of 1,724,042 procedures (1.3%). In a multivariable model controlling for age and other patient and surgical characteristics, the relative odds for urinary tract infection increased significantly with increasing frailty score. For example, compared to a frailty score of 0, the relative odds for urinary tract infection for a frailty score of 3 was 1.50 (95% confidence interval 1.41, 1.60). The relative odds associated with the maximum frailty score (5) was 2.50 (95% confidence interval 1.73, 3.61).

CONCLUSIONS

Frailty is associated with postoperative urinary tract infection, independent of age. Further research should focus on the underlying mechanisms and strategies to mitigate this risk among frail adults.

Controversies in Hypertension II: The Optimal Target Blood Pressure

The optimal target blood pressure in the treatment of hypertension is undefined. Whether more intense therapy is better than standard, typically <140/90 mm Hg, is controversial. The most recent American guidelines recommend ≤130/80 mm Hg for essentially all adults. There have been at least 28 trials targeting more versus less intensive therapy, including 13 aimed at reducing cardiovascular events and mortality, 11 restricted to patients with chronic kidney disease, and 4 with surrogate endpoints. We review these trials in a narrative fashion due to significant heterogeneity in targets chosen, populations studied, and primary endpoints. Most were negative, although some showed significant benefit to more intense therapy. When determining the optimal pressure for an individual patient, additional factors should be considered, including age, frailty, polypharmacy, baseline blood pressure, and the diastolic blood pressure J-curve. We discuss these modifying factors in detail. Whereas the tenet "lower is better" is generally true, one size does not fit all, and blood pressure control must be individualized.

The impact of minimally invasive surgery and frailty on post-hepatectomy outcomes

BACKGROUND

The impact of patient frailty on post-hepatectomy outcomes is not well studied. We hypothesized that patient frailty is a strong predictor of 30-day post-hepatectomy complications.

METHODS

The liver-targeted National Surgical Quality Improvement Program (NSQIP) database for 2014-2019 was reviewed. A validated modified frailty index (mFI) was used.

RESULTS

A total of 24,150 hepatectomies were reviewed. Worsening frailty was associated with increased incidence of Clavien-Dindo grade IV complications (mFI 0, 1, 2, 3, 4 was 3.9%, 6.3%, 10%, 8.1%, 50% respectively; p < 0.001). Minimally invasive hepatectomies had a lower rate of Clavien-Dindo grade IV complications for non-frail (Laparoscopic: 1%, Robotic: 2.6%, Open: 4.6%; p < 0.001) and frail patients (Laparoscopic: 3%, Robotic: 2.3%, Open: 7.7%; p < 0.001). Frail patients experienced higher incidence of post-hepatectomy liver failure (5.4% vs 4.1% for non-frail; p < 0.001) and grade C liver failure (28% vs 21.1% for non-frail; p = 0.03). Incorporating mFI to Albumin-Bilirubin score (ALBI) improved its ability to predict Clavien-Dindo grade IV complications (AUC improved from 0.609 to 0.647; p < 0.001) and 30-day mortality (AUC improved from 0.663 to 0.72; p < 0.001).

CONCLUSION

Worsening frailty correlates with increased incidence of Clavien-Dindo grade IV complications post-hepatectomy, whereas minimally invasive approaches decrease this risk. Incorporating frailty assessment to ALBI improves its ability to predict major postoperative complications and 30-day mortality.

Frailty assessment tools for use by surgeons when evaluating older adults prior to surgery: a scoping review protocol

INTRODUCTION

Despite growing evidence, uncertainty persists about which frailty assessment tools are best suited for routine perioperative care. We aim to understand which frailty assessment tools perform well and are feasible to implement.

METHODS AND ANALYSIS

Using a registered protocol following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA), we will conduct a scoping review informed by the Joanna Briggs Institute Guide for Scoping Reviews and reported using PRISMA extension for Scoping Reviews recommendations. We will develop a comprehensive search strategy with information specialists using the Peer Review of Electronic Search Strategies checklist, and implement this across relevant databases from 2005 to 13 October 2021 and updated prior to final review publication. We will include all studies evaluating a frailty assessment tool preoperatively in patients 65 years or older undergoing intracavitary, non-cardiac surgery. We will exclude tools not assessed in clinical practice, or using laboratory or radiologic values alone. After pilot testing, two reviewers will independently assess information sources for eligibility first by titles and abstracts, then by full-text review. Two reviewers will independently chart data from included full texts using a piloted standardised electronic data charting. In this scoping review process, we will (1) index frailty assessment tools evaluated in the preoperative clinical setting; (2) describe the level of investigation supporting each tool; (3) describe useability of each tool and (4) describe direct comparisons between tools. The results will inform ready application of frailty assessment tools in routine clinical practice by surgeons and other perioperative clinicians.

ETHICS AND DISSEMINATION

Ethic approval is not required for this secondary data analysis. This scoping review will be published in a peer-review journal. Results will be used to inform an ongoing implementation study focused on geriatric surgery to overcome the current lack of uptake of older adult-oriented care recommendations and ensure broad impact of research findings.

Metabolic Syndrome (MetS), Systemic Inflammatory Response Syndrome (SIRS), and Frailty: Is There any Room for Good Outcome in the Elderly Undergoing Emergency Surgery?

Background

Patients with MetS or SIRS experience higher rates of mortality and morbidity, across both cardiac and noncardiac surgery. Frailty assessment has acquired increasing importance in recent years as it predisposes elderly patients to a worse outcome. The aim of our study was to investigate the influence of MetS, SIRS, and with or without frailty on elderly patients undergoing emergency surgical procedures.

Methods

We analyzed data of all patients with nonmalignant diseases requiring an emergency surgical procedure from January 2017 to December 2020. The occurrence of MetS was identified using modified definition criteria used by the NCEP-ATP III Expert Panel: obesity, hypertension, diabetes, or if medication for high triglycerides or for low HDL cholesterol was taken. Systemic inflammatory response syndrome (SIRS) was evaluated according to the original consensus study (Sepsis-1). The frailty profile was investigated by the 5-modified Frailty Index (5-mFI) and the Emergency Surgery Frailty Index (EmSFI). Postoperative complications have been reported and categorized according to the Clavien-Dindo (C-D) classification system. Morbidity and mortality have been mainly considered as the 30-day standard period definition.

Results

Of the 2,318 patients included in this study, 1,010 (43.6%) fulfilled the criteria for MetS (MetsG group). Both 5-Items score and EmsFI showed greater fragility in patients with MetS. All patients with MetS showed more frequently a CACI index greater than 6. The occurrence of SIRS was higher in MetSG. LOS was longer in patients with MetS (MetSG 11.4 ± 12 days vs. n-MetSG 10.5 ± 10.2 days, p = 0.046). MetSG has a significantly higher rate of morbidity (353 (35.%) vs. 385 (29.4%), p = 0.005). The mortality rate in patients with MetS (98/1010, 10%) was similar to that in patients without it (129/1308, 10%). Considering patients with MetS who developed SIRS and those who had frailty or both, the occurrence of these conditions was associated with a higher rate of morbidity and mortality.

Conclusion

Impact of MetS and SIRS on elderly surgical patient outcomes has yet to be fully elucidated. The present study showed a 43.6% incidence of MetS in the elderly population. In conclusion, age per se should be not considered anymore as the main variable to estimate patient outcomes, while MetS and Frailty should have always a pivotal role.

The five-factor modified frailty index predicts adverse postoperative and chemotherapy outcomes in gynecologic oncology

INTRODUCTION

Frailty is increasingly recognized as a predictor of postoperative morbidity and oncologic outcomes. Evidence of the predictive value of frailty assessment in gynecologic oncology remains sparse.

OBJECTIVES

To evaluate the National Surgical Quality Improvement Program (NSQIP) comorbidity-based modified Frailty Index-5 (mFI-5) as predictor of severe postoperative complications, non-completion of chemotherapy and other patient-centered outcomes in gynecologic oncology patients >70 years-old undergoing surgery.

METHODS

Prospectively-collected NSQIP data and retrospective chart review of patients undergoing elective laparotomies for gynecologic malignances at a tertiary academic center in Ontario, Canada, between 01/2016-09/2020 were reviewed. Primary outcome was rate of 30-day Clavien-Dindo (Clavien) grade III-V complications. Secondary outcomes included Clavien II-V complications, postoperative length of stay (LOS), non-home discharge and non-completion of chemotherapy. Logistic regression analyses and receiver-operator curves were performed.

RESULTS

Two-hundred and fifty-nine patients were included; 103 were planned to receive adjuvant chemotherapy. Fifty-three patients (20.5%) had an mFI ≥ 2 and were categorized as frail. On multivariable analyses, frailty independently predicted grade III-V complications (OR 24.49, 95%CI 9.72-70.67, p < 0.0001), grade II-V complications (OR 4.64, 95%CI 2.31-9.94, p < 0.0001), non-home discharge (OR 7.37, 95%CI 2.81-20.46, p < 0.0001), LOS ≥ 7d (OR 3.6, 95% CI 1.54-8.6, p = 0.003) and non-completion of chemotherapy (OR 8.42, 95%CI 2.46-32.79, p = 0.001). Adjusted C-statistics demonstrated strong predictive value of the mFI-5 for grade III-V (0.92, 95%CI 0.86-0.97) and grade II-V (0.74, 95%CI 0.68-0.8) complications as well as non-home discharge (0.86, 95%CI 0.78-0.95) and chemotherapy non-completion (0.87, 95%CI 0.8-0.95).

CONCLUSION

Frailty as assessed with the mFI-5 predicted adverse postoperative and chemotherapy outcomes in gynecologic oncology patients aged ≥70 undergoing a laparotomy. The mFI-5 is a concise tool that can be used for routine frailty screening and risk stratification.

Efficacy of power training to improve physical function in individuals diagnosed with frailty and chronic disease: A meta-analysis

Muscle power training with emphasis on high-velocity of concentric movement improves physical functionality in healthy older adults, and, maybe superior to traditional exercise programs. Power training may also be advantageous for patients with acute and chronic illnesses, as well as frail individuals. To determine the efficacy of power training compared with traditional resistance training on physical function outcomes in individuals diagnosed with frailty, acute illness or chronic disease. PubMed (MEDLINE), CINAHL, PEDro, Web of Science, and Google Scholar. (1) at least one study group receives muscle power training of randomized controlled trial (RCT) (2) study participants diagnosed as prefrail, frail or have an ongoing acute or chronic disease, condition or illness; (3) study participants over the age of 18; (4) publication in English language; (5) included physical function as the primary or secondary outcome measures. Two independent reviewers assessed articles for inclusion and graded the methodological quality using Cochrane Risk-of-Bias tool for RCTs. Fourteen RCTs met the inclusion criteria. In seven studies, muscle power training was more effective at improving physical function compared to control activities with a mean fixed effect size (ES) of 0.41 (p = 0.006; 95% CI 0.12 to 0.71). Power training and conventional resistance training had similar effectiveness in eight studies with a mean fixed ES of 0.10 (p = 0.061; 95% CI -0.01 to 0.40). Muscle power training is just as efficacious for improving physical function in individuals diagnosed with frailty and chronic disease when compared to traditional resistance training. The advantages of power training with reduced work per session may support power training as a preferential exercise modality for clinical populations. The findings should be interpreted with caution since generalizability is questioned due to the heterogeneity of patient populations enrolled and participants were relatively mobile at baseline.

Effects of frailty on postoperative clinical outcomes of aneurysmal subarachnoid hemorrhage: results from the National Inpatient Sample database

Background

This study aimed to investigate the potential effect of preoperative frailty on postoperative clinical outcomes of patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods

Data of patients aged 18 years and older who were diagnosed with subarachnoid hemorrhage or intracerebral hemorrhage, underwent aneurysm repair surgical intervention from 2005 to 2014. A retrospective database analysis was performed based on U.S. National Inpatient Sample (NIS) from 2005 to 2014. Frailty was determined using the Johns Hopkins Adjusted Clinical Groups (ACG) frailty-defining diagnoses indicator. Patients were stratified into frail and non-frail groups and the study endpoints were incidence of postoperative complications and related adverse clinical outcomes.

Results

Among 20,527 included aSAH patients, 2303 (11.2%) were frail and 18,224 (88.8%) were non-frail. Significant differences were found between frailty and non-frailty groups in the four clinical outcomes (all p < 0.05). Multivariate analysis showed that frailty was associated with significant higher risks of discharge to institutional care (aOR: 2.50, 95%CI: 2.10–2.97), tracheostomy or gastrostomy tube replacement (aOR: 4.41, 95%CI: 3.81–5.10) and postoperative complications (aOR: 3.29, 95%CI: 2.55–4.25) but a lower risk of death in hospital (aOR: 0.40, 95%CI: 0.33–0.49) as compared with non-frailty. Stratified analysis showed the impact of frailty on some of the outcomes were greater among patients younger than 65 years than their older counterparts.

Conclusions

Frailty is significantly correlated with the increased risk of discharge to institutional care, tracheostomy or gastrostomy tube placement, and postoperative complications but with the reduced risk of in-hospital mortality outcomes after aneurysm repair. Frailty seems to have greater impact among younger adults than older ones. Baseline frailty evaluation could be applied to risk stratification for aSAH patients who were undergoing surgery.

Preoperative frailty based on laboratory data and postoperative health outcomes in patients undergoing coronary artery bypass graft surgery

BACKGROUND

Frailty is associated with adverse surgical outcomes. Patients with cardiovascular diseases have many risk factors of frailty; thus, preoperative frailty evaluation is necessary to predict adverse outcomes after coronary artery bypass graft (CABG) surgery. Laboratory data based-frailty assessments are objective and not time-consuming, addressing the need for an accurate but simple frailty screening for patients awaiting CABG surgery.

OBJECTIVES

This retrospective study aimed to determine the association between laboratory based-frailty and patient health outcomes after CABG surgery.

METHODS

We evaluated 896 patients who underwent on-pump or off-pump CABG surgery between August 1, 2015 and July 31, 2020 at a tertiary hospital. The frailty index-laboratory (FI-LAB), which comprises 32 laboratory parameters and vital signs, was used for frailty assessment.

RESULTS

The patients were divided into three groups according to their preoperative FI-LAB level as low (FI-LAB <0.25, 23.0%), moderate (FI-LAB ≥0.25 to ≤0.4, 54.9%), and high (FI-LAB>0.4, 22.1%) frailty groups. In the confounder-adjusted analysis, the lengths of hospital stay and intensive care unit stay were longer by 2.20 days (p=.023) and by 0.89 days (p=.009), respectively, in the high frailty group than those in the low frailty group. The odds ratio for 30-day readmission was also 2.58 times higher in the high frailty group than that in the low frailty group.

CONCLUSION

A high preoperative FI-LAB score indicates increasing risks of adverse postoperative outcomes among CABG surgery patients. FI-LAB has potential strengths to capture the need for a more thorough frailty assessment for cardiac surgery patients.
