Frailty as a predictor of surgical outcomes in older patients

Older age impacts outcomes after adrenalectomy

BACKGROUND

Adrenalectomy is well tolerated with low complication rates. It is unclear if these excellent outcomes are consistent across all age groups.

METHODS

The 2015-2020 American College of Surgeons National Surgical Quality Improvement Program datasets were used. Patients who underwent adrenalectomy were identified and grouped based on age: ≤60, 61 to 70, 71 to 80, and >80 years. Patient characteristics, surgical indications, operative characteristics, and postoperative outcomes were compared between age groups. Primary outcome measures were mortality, morbidity, postoperative length of stay, non-home discharge, and unplanned readmission. Multivariable logistic regression analysis was performed.

RESULTS

Adrenalectomy was performed on 6,114 patients. Younger patients more frequently had surgery for non-functional benign neoplasms compared with older (55.7% vs 52.8% vs 45.9% vs 45.3%, for patients ≤60, 61 to 70, 71 to 80, and >80 years, respectively, P < .001), and less frequently had surgery for malignancy (8.8% vs 14.4% vs 22.5% vs 24.5%, P < .001). The median length of stay for patients ≤60 was 1 day compared with 2 days for patients 61-70, 71-80, and >80 (P < .001). The overall mortality rate was <1% and did not differ based on age (P = .18). Morbidity occurred less frequently in the younger age groups (7.3% vs 8.9% vs 11.2% vs 16.0%, P < .001) compared with older. Similar trends were seen for non-home discharge (1.4% vs 2.5% vs 4.8% vs 17.0%, P < .001). On multivariable analysis, patients aged >80 had a 2-fold increased likelihood of morbidity and a 9-fold increased likelihood of non-home discharge compared to patients aged ≤60.

CONCLUSION

Older age is associated with morbidity and non-home discharge after adrenalectomy. Knowledge of these risks is critical when counseling an aging surgical population.

Preoperative evaluation of the elderly patient

Nowadays, the pre-operative evaluation of older patients is a critical step in the decision-making process. Clinical assessment and care planning should be considered a whole process rather than separate issues. Clinicians should use validated tools for pre-operative risk assessment of older patients to minimize surgery-related morbidity and mortality and enhance care quality. Traditional pre-operative consultation often fails to capture the pathophysiological and functional profiles of older patients. The elderly's pre-operative evaluation should be focused on determining the patient's functional reserve and reducing any possible peri-operative risk. Therefore, older adults may benefit from the Comprehensive Geriatric Assessment (CGA) that allows clinicians to evaluate several aspects of elderly life, such as depression and cognitive disorders, social status, multi-morbidity, frailty, geriatric syndromes, nutritional status, and polypharmacy. Despite the recognized challenges in applying the CGA, it may provide a realistic risk assessment for post-operative complications and suggest a tailored peri-operative treatment plan for older adults, including pre-operative optimization strategies. The older adults' pre-operative examination should not be considered a mere stand-alone, that is, an independent stage of the surgical pathway, but rather a vital step toward a personalized therapeutic approach that may involve professionals from different clinical fields. The aim of this review is to revise the evidence from the literature and highlight the most important items to be implemented in the pre-operative evaluation process in order to identify better all elderly patients' needs.

Geriatric anesthesia: Demographics, epidemiology, state of the art at international level, educational needs, and future perspectives

Population aging has induced in the last year a corresponding aging inside the surgical population, currently accounting for 45%.50% of the total surgical population in the majority of the advanced countries. This has induced a number of new challenges in the daily anesthesia practice, ranging from the need of implementing specific education in the field of geriatric medicine, organizational adjustments aimed to adapt our preoperative evaluation methodology to the needs older patients present, and a careful redesign of the whole perioperative course for these patients. Today's anesthesiologists are called to became familiar with the aging processes and their impact on the patho.physiological perioperative course, with the concept of functional impairment and frailty and with the dimensions of polypathology, polymedication, and reduced functional reserves. The introduction of new trends such as the team-based approach and interdisciplinary culture are essential to overcome these emerging criticalities.

Geriatric Surgery Produces a Hypoactive Molecular Phenotype in the Monocyte Immune Gene Transcriptome

Surgery is a major challenge for the immune system, but little is known about the immune response of geriatric patients to surgery. We therefore investigated the impact of surgery on the molecular signature of circulating CD14+ monocytes, cells implicated in clinical recovery from surgery, in older patients. We enrolled older patients having elective joint replacement (N = 19) or spine (N = 16) surgery and investigated pre- to postoperative expression changes in 784 immune-related genes in monocytes. Joint replacement altered the expression of 489 genes (adjusted p < 0.05), of which 38 had a |logFC| > 1. Spine surgery changed the expression of 209 genes (adjusted p < 0.05), of which 27 had a |logFC| > 1. In both, the majority of genes with a |logFC| > 1 change were downregulated. In the combined group (N = 35), 471 transcripts were differentially expressed (adjusted p < 0.05) after surgery; 29 had a |logFC| > 1 and 72% of these were downregulated. Notably, 21 transcripts were common across procedures. Thus, elective surgery in older patients produces myriad changes in the immune gene transcriptome of monocytes, with many suggesting development of an immunocompromised/hypoactive phenotype. Because monocytes are strongly implicated in the quality of surgical recovery, this signature provides insight into the cellular and molecular mechanisms of the immune response to surgery and warrants further study as a potential biomarker for predicting poor outcomes in older surgical patients.

Application of MFI-5 in severe complications and unfavorable outcomes after radical resection of colorectal cancer

BACKGROUND

Frailty is considered a characteristic manifestation of physiological decline in multiple organ systems, which significantly increases the vulnerability of elderly individuals with colorectal cancer (CRC) and is associated with a poor prognosis. While studies have demonstrated that the 11-factor Modified Frailty Index (mFI-11) can effectively predict adverse outcomes following radical resection of CRC, there is a lack of research on the applicability of the 5-factor Modified Frailty Index (mFI-5) within this patient population.

METHODS

In this retrospective analysis, we examined a cohort of CRC patients aged 65 years and above who had undergone radical resection. For each patient, we calculated their mFI-5 score, considering a score of ≥ 2 as an indication of frailty. We conducted univariate and multivariate analyses to assess the association between the mFI-5 and adverse outcomes as well as postoperative complications.

RESULTS

Patients with an mFI-5 score ≥ 2 exhibited a significantly higher incidence of serious postoperative complications (53% vs. 30%; P = 0.001) and experienced a longer hospital stay [19.00 (15.00-24.50) vs. 17.00 (14.00-20.00); P < 0.05]. Notably, an mFI-5 score greater than 2 emerged as an independent risk factor for severe postoperative complications (odds ratio: 2.297; 95% confidence interval: 1.216 to 4.339; P = 0.01). Furthermore, the mFI-5 score displayed predictive capabilities for severe postoperative complications with an area under the receiver operating characteristic (ROC) curve of 0.629 (95% confidence interval: 0.551 to 0.707; P < 0.05).

CONCLUSION

The mFI-5 demonstrates a high level of sensitivity in predicting serious complications, prolonged hospital stays, and mortality following radical resection of colorectal carcinoma. As a practical clinical assessment tool, the mFI-5 enables the identification of high-risk patients and facilitates preoperative optimization.

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.

Advances in the relationship between temporal muscle thickness and prognosis of patients with glioblastoma: a narrative review

The most dangerous variety of glioma, glioblastoma, has a high incidence and fatality rate. The prognosis for patients is still bleak despite numerous improvements in treatment approaches. We urgently need to develop clinical parameters that can evaluate patients' conditions and predict their prognosis. Various parameters are available to assess the patient's preoperative performance status and degree of frailty, but most of these parameters are subjective and therefore subject to interobserver variability. Sarcopenia can be used as an objective metric to measure a patient's physical status because studies have shown that it is linked to a bad prognosis in those with cancers. For the purpose of identifying sarcopenia, temporal muscle thickness has demonstrated to be a reliable alternative for a marker of skeletal muscle content. As a result, patients with glioblastoma may use temporal muscle thickness as a potential marker to correlate with the course and fate of their disease. This narrative review highlights and defines the viability of using temporal muscle thickness as an independent predictor of survival in glioblastoma patients, and it evaluates recent research findings on the association between temporal muscle thickness and prognosis of glioblastoma patients.

Supervised Home-Based Exercise Prehabilitation in Unfit Patients Scheduled for Pancreatic Surgery: Protocol for a Multicenter Feasibility Study

BACKGROUND

Morbidity rates in pancreatic surgery are high, and frail patients with low aerobic capacity are especially at risk of complications and require prophylactic interventions. Previous studies of small patient cohorts receiving intra-abdominal surgery have shown that an exercise prehabilitation program increases aerobic capacity, leading to better treatment outcomes.

OBJECTIVE

In this study, we aim to assess the feasibility of a home-based exercise prehabilitation program in unfit patients scheduled for pancreatic surgery on a larger scale.

METHODS

In this multicenter study, adult patients scheduled for elective pancreatic surgery with a preoperative oxygen uptake (VO2) at the ventilatory anaerobic threshold ≤13 mL/kg/min or a VO2 at peak exercise ≤18 mL/kg/min will be recruited. A total of 30 patients will be included in the 4-week, home-based, partly supervised exercise prehabilitation program. The program comprises 25-minute high-intensity interval training on an advanced cycle ergometer 3 times a week. Training intensity will be based on steep ramp test performance (ie, a short-term maximal exercise test on a cycle ergometer), aiming to improve aerobic capacity. Twice a week, patients will perform functional task exercises to improve muscle function and functional mobility. A steep ramp test will be repeated weekly, and training intensity will be adjusted accordingly. Next to assessing the feasibility (participation rate, reasons for nonparticipation, adherence, dropout rate, reasons for dropout, adverse events, and patient and therapist appreciation) of this program, individual patients' responses to prehabilitation on aerobic capacity, functional mobility, body composition, quality of life, and immune system factors will be evaluated.

RESULTS

Recruitment for this study began in January 2022 and is expected to be completed in the summer of 2023.

CONCLUSIONS

Results of this study will provide important clinical and scientific knowledge on the feasibility of a partly supervised home-based exercise prehabilitation program in a vulnerable patient population. This might ease the path to implementing prehabilitation programs in unfit patients undergoing complex abdominal surgery, such as pancreatic surgery.

Frailty and postoperative outcomes in brain tumor patients: a systematic review subdivided by tumor etiology

PURPOSE

Frailty has gained prominence in neurosurgical oncology, with more studies exploring its relationship to postoperative outcomes in brain tumor patients. As this body of literature continues to grow, concisely reviewing recent developments in the field is necessary. Here we provide a systematic review of frailty in brain tumor patients subdivided by tumor type, incorporating both modern frailty indices and traditional Karnofsky Performance Status (KPS) metrics.

METHODS

Systematic literature review was performed using PRISMA guidelines. PubMed and Google Scholar were queried for articles related to frailty, KPS, and brain tumor outcomes. Only articles describing novel associations between frailty or KPS and primary intracranial tumors were included.

RESULTS

After exclusion criteria, systematic review yielded 52 publications. Amongst malignant lesions, 16 studies focused on glioblastoma. Amongst benign tumors, 13 focused on meningiomas, and 6 focused on vestibular schwannomas. Seventeen studies grouped all brain tumor patients together. Seven studies incorporated both frailty indices and KPS into their analyses. Studies correlated frailty with various postoperative outcomes, including complications and mortality.

CONCLUSION

Our review identified several patterns of overall postsurgical outcomes reporting for patients with brain tumors and frailty. To date, reviews of frailty in patients with brain tumors have been largely limited to certain frailty indices, analyzing all patients together regardless of lesion etiology. Although this technique is beneficial in providing a general overview of frailty's use for brain tumor patients, given each tumor pathology has its own unique etiology, this combined approach potentially neglects key nuances governing frailty's use and prognostic value.

Efficiency, Safety, Quality, and Empathy: Balancing Competing Perioperative Challenges in the Elderly

Although baby boomer generation accounts for a little more than 15% of the US population, the cohort represents a disproportionate percentage of patients undergoing surgery. As this group continues to age, a multitude of challenges have arisen in health care regarding the safest and most effective means of providing anesthesia services to these patients. Many elderly patients may be exquisitely sensitive to the effects of anesthesia and surgery and may experience cognitive and physical decline before, during, or after hospital admission. In this review article, the authors briefly examine the physiologic processes underlying aging and explore steps necessary to deliver safe, empathetic care.

Patient selection in ambulatory surgery

Patient selection is important for ambulatory surgical practices. Proper patient selection for ambulatory practices will optimize resources and lead to increased patient and provider satisfaction. As the number and complexity of procedures in ambulatory surgical centers increase, it is important to ensure that patients are best cared for in facilities that can provide appropriate levels of care. This review addresses the multiple variables and resources that should be considered when selecting patients for anesthesia in ambulatory centers and offices.

The prognostic value of clinical frailty and American Society of Anesthesiology score in patients with chronic limb threatening ischaemia

Background: Frailty is a complex multisystem syndrome associated with increased comorbidity and decreased physiological reserve. There are associations between frailty and adverse outcome in surgical patients. Chronic limb threatening ischemia (CLTI) is increasingly prevalent, with a typically frail patient population. Existing frailty scoring systems focus on functional measures and do not reliably assess comorbidities. The present study aims to describe the prognostic value of multimodal frailty assessment in patients with CLTI. Patients and methods: Patients >50 years old admitted as an emergency with CLTI between May 2020 to June 2021 were included. Frailty was measured using Clinical Frailty Score (CFS), and comorbidities with American Society of Anesthiologists score (ASA). A composite score combining CFS and ASA was derived and the prognostic value compared with each component score. The primary outcome was overall survival. Results: There were 249 eligible patients, 53.4% (n=133) had CFS>4. The mean (95% CI) overall survival for the CFS>4 cohort was 15.9 (13.6-18.3) months vs. 28.5 (26.1-30.9) months for CFS≤4 cohort (p<0.001). Increasing CFS-ASA score was associated with inferior survival on univariate (HR=2.84, 95% CI [1.96-4.11], p<0.001) and multivariate (HR=1.78, 95% CI [1.20-2.64], p<0.01) analyses. ROC-analysis showed comparable prognostic value of CFS and CFS-ASA to predict one-year survival. Conclusions: Frailty is highly prevalent and a poor prognostic indicator in patients with CLTI admitted as an emergency. Our results suggest that incorporating assessment of comorbidities into frailty assessment may offer prognostic value, but comparable to existing clinical frailty assessment. Further work to identify patients with inferior prognosis is required.

Association between sarcopenia and postoperative complications in patients undergoing surgery for gastrointestinal or hepato-pancreatico-biliary cancer

BACKGROUND AND OBJECTIVES

Despite surgical advances, postoperative complications persist, affecting oncologic outcomes and increasing treatment costs. It is important to identify a marker that can predict postoperative complications, which can help prehabilitate patients before surgery. This study evaluated sarcopenia as a predictive marker of postoperative complications in patients undergoing surgery for gastrointestinal (GI) or hepato-pancreatico-biliary (HPB) cancer.

METHODS

Sarcopenia was assessed using the skeletal muscle index at the third lumbar vertebra on abdominal computed tomography. The predictive ability of sarcopenia was evaluated by adjusting for other clinicopathological factors.

RESULTS

Of the 210 patients, 81 (38.57%) were sarcopenic. The overall morbidity and mortality were 33.81% and 2.86%, respectively. Major complications (Clavien-Dindo Grade ≥ III) were observed in 10.95% patients and sarcopenic patients were significantly more likely to develop major complications (p = 1.42 × 10-10 ). Sarcopenia (p = 6.13 × 10-6 ; odds ratio = 12.29) independently predicted postoperative complications and prolonged hospital stay (p = 0.01).

CONCLUSION

Sarcopenia objectively predicted the development of postoperative complications and prolonged hospital stay in patients undergoing surgery for GI or HPB cancer. This may facilitate the prehabilitation of patients planned for surgery to reduce the risk of complications.

Surgical outcome improvement by shared decision-making: value of a preoperative multidisciplinary target clinic for the elderly in colorectal surgery

PURPOSE

Frailty and comorbidities increase the risk of postoperative complications and raise treatment costs. Perioperative optimisation is shown to improve surgical outcomes for the elderly. The aim of this study was to assess the impact of introducing a multidisciplinary preoperative clinic for older patients (Colchester Older Persons' Evaluation for Surgery (COPES) clinic) undergoing major colorectal surgery.

METHODS

This 5-year single centre study included patients >65 years with ≥3 comorbidities undergoing major colorectal surgery. From October 2018, patients with these characteristics were evaluated and optimised in the COPES clinic by a geriatrician and an anaesthetist. Outcomes were compared to high-risk patients operated on prior to COPES (pre-COPES group). The primary outcomes were postoperative morbidity at discharge and 6 months measured by the Comprehensive Complication Index. Patients were matched on age and number of comorbidities.

RESULTS

A total of 54 patients were enrolled in the pre-COPES and 18 in the COPES group. After matching, the results were comparable for both groups. The length of stay was shorter in the COPES group and the recurrence rate was higher; however, it did not reach statistical significance in both findings.

CONCLUSION

This clinic intends to improve treatment quality, placing emphasis on shared decision-making. More focus should be put on patient-reported outcomes and experiences. Especially for elderly patients, quality of life and maintaining independence are often their priority. To determine the true value of a preoperative multidisciplinary clinic targeting elderly comorbid patients, a prospective study with larger cohort is needed, focusing not only on objective outcomes but also on patient-reported outcomes.

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.

Racial disparities in inpatient palliative care consultation among frail older patients undergoing high-risk elective surgical procedures in the United States: a cross-sectional study of the national inpatient sample

Surgical interventions are common among seriously ill older patients, with nearly one-third of older Americans facing surgery in their last year of life. Despite the potential benefits of palliative care among older surgical patients undergoing high-risk surgical procedures, palliative care in this population is underutilized and little is known about potential disparities by race/ethnicity and how frailty my affect such disparities. The aim of this study was to examine disparities in palliative care consultations by race/ethnicity and assess whether patients' frailty moderated this association. Drawing on a retrospective cross-sectional study of inpatient surgical episodes using the National Inpatient Sample of the Healthcare Cost and Utilization Project from 2005 to 2019, we found that frail Black patients received palliative care consultations least often, with the largest between-group adjusted difference represented by Black-Asian/Pacific Islander frail patients of 1.6 percentage points, controlling for sociodemographic, comorbidities, hospital characteristics, procedure type, and year. No racial/ethnic difference in the receipt of palliative care consultations was observed among nonfrail patients. These findings suggest that, in order to improve racial/ethnic disparities in frail older patients undergoing high-risk surgical procedures, palliative care consultations should be included as the standard of care in clinical care guidelines.

Advances in the Management of Acute Postsurgical Pain: A Review

Despite the millions of surgeries performed every year around the world, postoperative pain remains prevalent and is often addressed with inadequate or suboptimal treatments. Chronic postsurgical pain is surprisingly prevalent, and its rate varies with the type of surgery, as well as with certain patient characteristics. Thus, better clinical training is needed as well as patient education. As pain can be caused by more than one mechanism, multimodal or balanced postsurgical analgesia is appropriate. Pharmacological agents such as opioid and nonopioid pain relievers, as well as adjuvants and nonpharmacologic approaches, can be combined to provide better and opioid-sparing pain relief. Many specialty societies have guidelines for postoperative pain management that emphasize multimodal postoperative analgesia. These guidelines are particularly helpful when dealing with special populations such as pregnant patients or infants and children. Pediatric pain control, in particular, can be challenging as patients may be unable to communicate their pain levels. A variety of validated assessment tools are available for diagnosis. Related to therapy, most guidelines agree on the fact that codeine should be used with extreme caution in pediatric patients as some may be "rapid metabolizers" and its use may be life-threatening. Prehabilitation is a preoperative approach that prepares patients in advance of elective surgery with conditioning exercises and other interventions to optimize their health. Prehabilitation may have aerobic, strength-training, nutritional, and counseling components. Logistical considerations and degree of patient adherence represent barriers to effective prehabilitation programs. Notwithstanding all this, acute postoperative pain represents a clinical challenge that has not yet been well addressed.

Measuring Frailty Using Patient-Reported Outcomes (PRO) Data: A Feasibility Study in Patients with Multiple Myeloma

PURPOSE

The objective of this retrospective study was to determine the feasibility of measuring frailty using patient responses to relevant EORTC QLQ-C30 items as proxy criteria for the Fried Frailty Phenotype, in a cohort of patients with Relapsed/Refractory Multiple Myeloma (RRMM).

METHODS

Data were pooled from nine Phase III randomized clinical trials submitted to the FDA for regulatory review between 2010 and 2021, for the treatment of RRMM. Baseline EORTC QLQ-C30 responses were used to derive a patient-reported frailty phenotype (PRFP), based on the Fried definition of frailty. PRFP was assessed for internal consistency reliability, structural validity, and known groups validity.

RESULTS

This study demonstrated the feasibility of adapting patient responses to relevant EORTC QLQ-C30 items to serve as proxy Fried frailty criteria. Selected items were well correlated with one another and PRFP as a whole demonstrated adequate internal consistency reliability and structural validity. Known groups analysis demonstrated that PRFP could be used to detect distinct comorbidity levels and distinguish between different functional profiles, with frail patients reporting more difficulty in walking about, washing/dressing, and doing usual activities, as compared to their pre-frail and fit counterparts. Among the 4928 patients included in this study, PRFP classified 2729 (55.4%) patients as fit, 1209 (24.5%) as pre-frail, and 990 (20.1%) as frail.

CONCLUSION

Constructing a frailty scale from existing PRO items commonly collected in cancer trials may be a patient-centric and practical approach to measuring frailty. Additional psychometric evaluation and research is warranted to further explore the utility of such an approach.

One-Year Survival after Cardiac Surgery in Frail Older People-Social Support Matters: A Prospective Cohort Study

There are increasing rates of cardiac surgery in the elderly. Frailty, depression, and social vulnerability are frequently present in older people, and should be considered while assessing risk and providing treatment options. We aimed to analyse the impact of clinically relevant variables on survival at one year, and identify areas of future intervention. We performed a prospective cohort study at a University Hospital, with a sample of 309 elective cardiac surgery patients 65 years old and over. Their socio-demographic and clinical variables were collected. Frailty prevalence was 61.3%, while depression was absent in the majority of patients. Mortality was 1.6% and 7.8% at 30 days and 12 months, respectively. After Kaplan-Meier analysis, severe frailty (p = 0.003), severe depression (p = 0.027), pneumonia until 30 days (p = 0.014), and re-operation until 12 months (p = 0.003) significantly reduced survival, while social support increased survival (p = 0.004). In the adjusted multivariable Cox regression model, EuroSCORE II (HR = 1.27 [95% CI 1.069-1.499] p = 0.006), pneumonia until 30 days (HR = 4.19 [95% CI 1.169-15.034] p = 0.028), re-intervention until 12 months (HR = 3.14 [95% CI 1.091-9.056] p = 0.034), and social support (HR = 0.24 [95% CI 0.079-0.727] p = 0.012) explained time until death. Regular screening for social support, depression, and frailty adds relevant information regarding risk stratification, perioperative interventions, and decision-making in older people considered for cardiac surgery.

Surgery for Metastatic Spinal Disease in Octogenarians and Above: Analysis of 78 Patients

STUDY DESIGN

Retrospective Cohort Study.

OBJECTIVE

Octogenarians living with spinal metastases are a challenging population to treat. Our objective was to identify the rate, types, management, and predictors of complications and survival in octogenarians following surgery for spinal metastases.

METHODS

A retrospective review of a prospectively collected cohort of patients aged 80 years or older who underwent surgery for metastatic spinal tumor treatment between 2008 and 2019 were included. Demographic, intraoperative, complications, and postoperative follow-up data was collected. Cox proportional hazards regression and logistic regression were used to associate variables with overall survival and postoperative complications, respectively.

RESULTS

78 patients (mean 83.6 years) met inclusion criteria. Average operative time and blood loss were 157 minutes and 615 mL, respectively. The median length of stay was 7 days. The overall complication rate was 31% (N = 24), with 21% considered major and 7% considered life-threatening or fatal. Blood loss was significantly associated with postoperative complications (OR = 1.002; P = 0.02) and mortality (HR = 1.0007; P = 0.04). Significant associations of increased risk of death were also noted with surgeries with decompression, and cervical/cervicothoracic index level of disease. For deceased patients, median time to death was 4.5 months. For living patients, median follow-up was 14.5 months. The Kaplan-Meier based median overall survival for the cohort was 11.6 months (95% CI: 6.2-19.1).

CONCLUSIONS

In octogenarians undergoing surgery with instrumentation for spinal metastases, the median overall survival is 11.6 months. There is an increased complication rate, but only 7% are life-threatening or fatal. Patients are at increased risk for complications and mortality particularly when performing decompression with stabilization, with increasing intraoperative blood loss, and with cervical/cervicothoracic tumors.

The impact of frailty on ventral hernia repair outcomes in a statewide database

INTRODUCTION

Preoperative frailty is a strong predictor of postoperative morbidity in the general surgery population. Despite this, there are a paucity of research examining the effect of frailty on outcomes after ventral hernia repair (VHR), one of the most common abdominal operations in the USA. We examined the association of frailty with short-term postoperative outcomes while accounting for differences in preoperative, operative, and hernia characteristics.

METHODS

We retrospectively reviewed the Michigan Surgery Quality Collaborative Hernia Registry (MSQC-HR) for adult patients who underwent VHR between January 2020 and January 2022. Patient frailty was assessed using the validated 5-factor modified frailty index (mFI5) and categorized as follows: no (mFI5 = 0), moderate (mFI5 = 1), and severe frailty (mFI5 ≥ 2). Our primary outcome was any 30-day complication. Multivariable logistic regression was used to evaluate the association of frailty with outcomes while controlling for patient, operative, and hernia variables.

RESULTS

A total of 4406 patients underwent VHR with a mean age (SD) of 55 (15) years, 2015 (46%) females, and 3591 (82%) white patients. The mean (SD) BMI of the cohort was 33 (8) kg/m2. A total of 2077 (47%) patients had no frailty, 1604 (36%) were moderately frail, and 725 (17%) were severely frail. The median hernia size (interquartile range) was 2.5 cm (1.5-4.0 cm). Severe frailty was associated with increased odds of any complication (adjusted Odds Ratio (aOR) 3.12, 95% CI 1.78-5.47), serious complication (aOR 5.25, 95% CI 2.17-13.19), SSI (aOR 3.41, 95% CI 1.58-7.34), and post-discharge adverse events (aOR 1.70, 95% CI 1.24-2.33).

CONCLUSION

After controlling for patient, operative, and hernia characteristics, frailty was independently associated with increased odds of postoperative complications. These findings highlight the importance of preoperative frailty assessment for risk stratification and to inform patient counseling.

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.

The Impact of Frailty on Postoperative Complications in Total En Bloc Spondylectomy for Spinal Tumors

Total en bloc spondylectomy (TES) is an effective treatment for spinal tumors. However, its complication rate is high, and the corresponding risk factors remain unclear. This study aimed to clarify the risk factors for postoperative complications after TES, including the patient's general condition, such as frailty and their levels of inflammatory biomarkers. We included 169 patients who underwent TES at our hospital from January 2011-December 2021. The complication group comprised patients who experienced postoperative complications that required additional intensive treatments. We analyzed the relationship between early complications and the following factors: age, sex, body mass index, type of tumor, location of tumor, American Society of Anesthesiologists score, physical status, frailty (categorized by the 5-factor Modified Frailty Index [mFI-5]), neutrophil-to-lymphocyte ratio, C-reactive protein/albumin ratio, preoperative chemotherapy, preoperative radiotherapy, surgical approach, and the number of resected vertebrae. Of the 169 patients, 86 (50.1%) were included in the complication group. Multivariate analysis showed that high mFI-5 scores (odds ratio [OR] = 2.99, p < 0.001) and an increased number of resected vertebrae (OR = 1.87, p = 0.018) were risk factors for postoperative complications. Frailty and the number of resected vertebrae were independent risk factors for postoperative complications after TES for spinal tumors.

Implementation of a novel nursing assessment tool in geriatric trauma patients with proximal femur fractures

BACKGROUND

Geriatric trauma patients represent a special challenge in postoperative care and are prone to specific complications. The goal of this study was to analyse the predictive potential of a novel nursing assessment tool, the outcome-oriented nursing assessment for acute care (ePA-AC), in geriatric trauma patients with proximal femur fractures (PFF).

METHODS

A retrospective cohort study of geriatric trauma patients aged ≥ 70 years with PFF was conducted at a level 1 trauma centre. The ePA-AC is a routinely used tool that evaluates pneumonia; confusion, delirium and dementia (CDD); decubitus (Braden Score); the risk of falls; the Fried Frailty index (FFI); and nutrition. Assessment of the novel tool included analysis of its ability to predict complications including delirium, pneumonia and decubitus.

RESULTS

The novel ePA-AC tool was investigated in 71 geriatric trauma patients. In total, 49 patients (67.7%) developed at least one complication. The most common complication was delirium (n = 22, 44.9%). The group with complications (Group C) had a significantly higher FFI compared with the group without complications (Group NC) (1.7 ± 0.5 vs 1.2 ± 0.4, p = 0.002). Group C had a significantly higher risk score for malnutrition compared with Group NC (6.3 ± 3.4 vs 3.9 ± 2.8, p = 0.004). A higher FFI score increased the risk of developing complications (odds ratio [OR] 9.8, 95% confidence interval [CI] 2.0 to 47.7, p = 0.005). A higher CDD score increased the risk of developing delirium (OR 9.3, 95% CI 2.9 to 29.4, p < 0.001).

CONCLUSION

The FFI, CDD, and nutritional assessment tools are associated with the development of complications in geriatric trauma patients with PFF. These tools can support the identification of geriatric patients at risk and might guide individualised treatment strategies and preventive measures.

Do ethnic chinese older adults with epithelial ovarian cancer survive a poorer prognosis?

BACKGROUND

The risk of suffering epithelial ovarian cancer (EOC) for women increases with age evidently, while the prognosis of older EOC patients remain unclear. Against the backdrop of the accelerate aging process in China, this paper investigates whether the older EOC patients have a lower overall survival probability than the younger patients based on the sample of ethnic Chinese population.

METHODS

A total of 323 ethnic Chinese patients diagnosed as epithelial ovarian cancer were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We compared the overall survival probability between the younger group (< 70 years) and the older patients group (≥ 70 years). Survival curves were drawn using the Kaplan-Meier method, comparisons among different subgroups were evaluated using log-rank tests, and independent prognostic factors were identified by univariate and multivariate Cox regression analyses.

RESULTS

43 patients were (13.3%) in the older patients group and 280 (86.7%) in the younger group. The distribution patterns between two groups were significantly different with regard to marital status, histologic type and FIGO stage. The median overall survival (OS) was significantly longer in the younger group than the older patients group (not reached vs. median 39 months, p < 0.05). The multivariate analysis demonstrated that the age (The older vs. the younger, HR: 1.967, P = 0.007), primary tumor laterality (HR: 1.849, P = 0.009), and FIGO stage (III vs. I, HR: 3.588, P = 0.001; and IV vs. I, HR: 4.382, P = 0.001; respectively) remained as important risk factors while Histology (HGSOC vs. CCOC, HR: 0.479, P = 0.025; and LGSOC/MOC/EC vs. CCOC, HR: 0.390, P = 0.034; respectively) and the number of lymph node dissected more than 10 was a protective factor (HR: 0.397, P = 0.008). In an analysis of 104 pairs of patients matched on the basis of the propensity score, the older patients group had significantly lower overall mortality (HR = 2.561, P = 0.002).

CONCLUSION

Ethnic Chinese Older EOC patients have a worse prognosis than the younger patients.

Efficacy of Transforaminal Endoscopic Lumbar Discectomy in Elderly Patients Over 65 Years of Age Compared to Young Adults

OBJECTIVE

Spine surgery rates are increasing in the elderly population due to social aging, and it is known that prognoses related to surgery are worse for the elderly compared to younger individuals. However, minimally invasive surgery, such as full endoscopic surgery, is considered safe with low complication rates due to minimal damage to surrounding tissues. In this study, we compared outcomes of transforaminal endoscopic lumbar discectomy (TELD) in elderly and younger patients with disc herniation in the lumbosacral region.

METHODS

We retrospectively analyzed the data of 249 patients who underwent TELD at a single center between January 2016 to December 2019, with a minimum follow-up of 3 years. Patients were allocated to 2 groups: a young group aged ≤ 65 years (n = 202) or an elderly group aged > 65 years (n = 47). We evaluated baseline characteristics, clinical outcomes, surgery-related outcomes, radiological outcomes, perioperative complications, and adverse events during the 3-year follow-up period.

RESULTS

Baseline characteristics, including age, general condition based on American Society of Anesthesiologist physical status classification grade, age-Charlson Comorbidity Index, and disc degeneration, were worse in elderly group (p < 0.001). However, except for leg pain at 4 weeks after surgery, overall outcomes, including pain improvement, radiological change, operation time, blood loss, and hospital stay, were not different between the 2 groups. Furthermore, the rates of perioperative complications (9 patients [4.46%] in the young group and 3 patients [6.38%] in the elderly group, p = 0.578) and adverse events over the 3-year follow-up period (32 patients [15.84%] in the young group and 9 patients [19.15%] in the elderly group, p = 0.582) were comparable in the 2 groups.

CONCLUSION

Our findings suggest that TELD produces similar outcomes in both elderly and younger patients with a herniated disc in the lumbosacral region. TELD can be considered a safe option for appropriately selected elderly patients.

Liver transplantation in the patient with physical frailty

Frailty is a decline in functional reserve across multiple physiological systems. A key component of frailty is sarcopenia, which denotes a loss of skeletal muscle mass and impaired contractile function that ultimately result in physical frailty. Physical frailty/sarcopenia are frequent and contribute to adverse clinical outcomes before and after liver transplantation. Frailty indices, including the liver frailty index, focus on contractile dysfunction (physical frailty), while cross-sectional image analysis of muscle area is the most accepted and reproducible measure to define sarcopenia. Thus, physical frailty and sarcopenia are interrelated. The prevalence of physical frailty/sarcopenia is high in liver transplant candidates and these conditions have been shown to adversely impact clinical outcomes including mortality, hospitalisations, infections, and cost of care both before and after transplantation. Data on the prevalence of frailty/sarcopenia and their sex- and age-dependent impact on outcomes are not consistent in patients on the liver transplant waitlist. Physical frailty and sarcopenic obesity are frequent in the obese patient with cirrhosis, and adversely affect outcomes after liver transplantation. Nutritional interventions and physical activity remain the mainstay of management before and after transplantation, despite limited data from large scale trials. In addition to physical frailty, there is recognition that a global evaluation including a multidisciplinary approach to other components of frailty (e.g., cognition, emotional, psychosocial) also need to be addressed in patients on the transplant waitlist. Recent advances in our understanding of the underlying mechanisms of sarcopenia and contractile dysfunction have helped identify novel therapeutic targets.

Management of Prostate Cancer in Older Adults

The majority of men with prostate cancer are diagnosed when they are older than 65 years; however, clinical trial participants are disproportionately younger and more fit than the real-world population treated in typical clinical practices. It is, therefore, unknown whether the optimal approach to prostate cancer treatment is the same for older men as it is for younger and/or more fit men. Short screening tools can be used to efficiently assess frailty, functional status, life expectancy, and treatment toxicity risk. These risk assessment tools allow for targeted interventions to increase a patient's reserve and improve treatment tolerance, potentially allowing more men to experience the benefit of the significant recent treatment advances in prostate cancer. Treatment plans should also take into consideration each patient's individual goals and values considered within their overall health and social context to reduce barriers to care. In this review, we will discuss evidence-based risk assessment and decision tools for older men with prostate cancer, highlight intervention strategies to improve treatment tolerance, and contextualize these tools within the current treatment landscape for prostate cancer.

Preoperative frailty vs. cognitive impairment: Which one matters most for postoperative delirium among older adults with cancer?

INTRODUCTION

Limited data are available to explore the association between preoperative frailty and cognitive impairment with postoperative delirium among older adults with cancer. We explored this association in a single Comprehensive Cancer Center where postoperative delirium and frailty are assessed in routine care using the Confusion Assessment Method (CAM) and Memorial Sloan Kettering Frailty Index (MSK-FI), respectively.

MATERIALS AND METHODS

Retrospective study on patients with cancer, aged 65+, who underwent surgery from April 2018 to March 2019 with hospital stay ≥1 day. We used logistic regression with postoperative delirium as the outcome, primary predictor MSK-FI, adjusted for age, operative time, and preoperative albumin. As the MSK-FI includes a component related to cognitive impairment, we additionally evaluated the impact of this component, separately from the rest of the score, on the association between frailty and postoperative delirium.

RESULTS

Among 1,257 patients with available MSK-FI and CAM measures, 47 patients (3.7%) had postoperative delirium. Increased frailty was associated with increased risk of postoperative delirium (odds ratio [OR] 1.51; 95% confidence interval [CI] 1.26, 1.81; p < 0.001). However, this was largely related to the effect of cognitive impairment (OR 15.29; 95% CI 7.18; 32.56; p < 0.001). In patients with cognitive impairment, the association between frailty and postoperative delirium was not significant (OR 0.97; 95% CI 0.65, 1.44; p-value = 0.9), as having cognitive impairment put patients at high risk for postoperative delirium even without taking into account the other components of the MSK-FI. While the association between frailty and postoperative delirium in patients with intact cognitive function was statistically significant (OR 1.58; 95% CI 1.27, 1.96; p < 0.001), it was not clinically meaningful, particularly considering the low risk of delirium among patients with intact cognitive function (e.g., 1.3% vs 3.2% for MSK-FI 1 vs 3).

DISCUSSION

Cognitive function should be a greater focus than frailty, as measured by the MSK-FI, in preoperative assessment for the prediction of postoperative delirium.

Interpreting the risk analysis index of frailty in the context of surgical oncology

BACKGROUND AND OBJECTIVES

The Risk Analysis Index (RAI) accurately predicts adverse postoperative outcomes but the inclusion of cancer status in the RAI has raised two key concerns about its suitability for use in surgical oncology: (1) the potential over classification of cancer patients as frail, and (2) the potential overestimation of postoperative mortality for patients with surgically curable cancers.

METHODS

We performed a retrospective cohort analysis to assess the RAI's power to appropriately identify frailty and predict postoperative mortality in cancer patients. We assessed discrimination for mortality and calibration across five RAI models-the complete RAI and four variants that removed different cancer-related variables.

RESULTS

We found that the presence of disseminated cancer was a key variable driving the RAI's power to predict postoperative mortality. The model including only this variable [RAI (disseminated cancer)] was similar to the complete RAI in the overall sample (c = 0.842 vs. 0.840) and outperformed the complete RAI in the cancer subgroup (c = 0.736 vs 0.704, respectively, p < 0.0001, Max R2  = 19.3% vs. 15.1%, respectively).

CONCLUSION

The RAI demonstrates somewhat less discrimination when applied exclusively to cancer patients, but remains a strong predictor of postoperative mortality, especially in the setting of disseminated cancer.

Association of Comorbidities and Functional Level With Mortality in Geriatric Bowel Perforation

INTRODUCTION

Spontaneous bowel perforation is associated with high morbidity and mortality. This entity remains understudied in the geriatric patient. We sought to use a national surgical sample to uncover independent predictors of mortality in elderly patients undergoing emergent operation for perforated bowel.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement database, years 2007 to 2017, all geriatric patients (age ≥65 y) who underwent emergency surgery and who had a postoperative diagnosis of bowel perforation were included. Univariate and multivariable analyses were used to identify independent predictors of 30-d mortality.

RESULTS

A total of 8981 patients were included. The median (interquartile range) age was 75 y (69, 82), and 59.0% were female. Twenty-one percent of patients were partially or totally dependent, and 25.2% were admitted from sources other than home. Overall, 30-d mortality rate was 22.1%. Independent predictors of mortality included the following: age 70-79 y (odds ratio [OR]: 1.59, P < 0.001), age ≥80 y (OR: 3.23, P < 0.001), American Society of Anesthesiologists ≥3 (OR: 4.74, P < 0.001), admission from chronic care facility (OR: 1.61, P < 0.001), being partially or totally dependent (OR: 1.50, P < 0.001), chronic steroid use (OR: 1.36, P < 0.001), and preoperative septic shock (OR: 3.74, P < 0.001). Having immediate fascial closure was protective against mortality (immediate fascial closure only, OR: 0.55, P < 0.001; -immediate closure of all surgical site layers, OR: 0.44, P < 0.001).

CONCLUSIONS

In geriatric patients, functional status and chronic steroid therapy play an important role in determining survival following surgery for bowel perforation. These factors should be considered during preoperative counseling and decision-making.

Surgery for glioblastomas in the elderly: an Association des Neuro-oncologues d'Expression Française (ANOCEF) trial

OBJECTIVE

The role of surgery in the treatment of malignant gliomas in the elderly is not settled. The authors conducted a randomized trial that compared tumor resection with biopsy only-both followed by standard therapy-in such patients.

METHODS

Patients ≥ 70 years of age with a Karnofsky Performance Scale (KPS) score ≥ 50 and presenting with a radiological suspicion of operable glioblastoma (GBM) were randomly assigned between tumor resection and biopsy groups. Subsequently, they underwent standard radiotherapy during the first years of the trial (2008-2017), with the addition of adjunct therapy with temozolomide when this regimen became standard (2017-2019). The primary endpoint was survival, and secondary endpoints were progression-free survival (PFS), cognitive status (Mini-Mental State Examination), autonomy (KPS), quality of life (European Organisation for Research and Treatment of Cancer [EORTC] QLQ-C30 and QLQ-BN20), and perioperative morbidity and mortality.

RESULTS

Between 2008 and 2019, 107 patients from 9 centers were enrolled in the study; 101 were evaluable for analysis because a GBM was histologically confirmed (50 in the surgery arm and 51 in the biopsy arm). There was no statistically significant difference in median survival between the surgery (9.37 months) and the biopsy (8.96 months, p = 0.36) arms (adjusted HR 0.79, 95% CI 0.52-1.21, p = 0.28). However, the surgery group had an increased PFS (5.06 vs 4.02 months; p = 0.034) (adjusted HR 0.50, 95% CI 0.32-0.78, p = 0.002). Less deterioration of quality of life and KPS score evolution than in the biopsy group was observed. Surgery was not associated with increased mortality or morbidity.

CONCLUSIONS

This study suggests that debulking surgery is safe, and-compared to biopsy-is associated with a less severe deterioration of quality of life and autonomy, as well as a significant although modest improvement of PFS in elderly patients suffering from newly diagnosed malignant glioma. Although resection does not provide a significant survival benefit in the elderly, the authors believe that the risk/benefit analysis favors an attempt at optimal tumor resection in this population, provided there is careful preoperative geriatric evaluation.

Association of Routine Preoperative Frailty Assessment With 1-Year Postoperative Mortality

Importance

Patient frailty is a known risk factor for adverse outcomes following surgery, but data are limited regarding whether systemwide interventions related to frailty are associated with improved patient outcomes.

Objective

To evaluate whether a frailty screening initiative (FSI) is associated with reduced late-term mortality after elective surgery.

Design, Setting, and Participants

This quality improvement study with an interrupted time series analysis used data from a longitudinal cohort of patients in a multihospital, integrated health care system in the US. Beginning in July 2016, surgeons were incentivized to measure frailty with the Risk Analysis Index (RAI) for all patients considering elective surgery. Implementation of the BPA occurred in February 2018. The cutoff for data collection was May 31, 2019. Analyses were conducted between January and September 2022.

Exposures

The exposure of interest was an Epic Best Practice Alert (BPA) used to identify patients with frailty (RAI ≥42) and prompt surgeons to document a frailty-informed shared decision-making process and consider additional evaluation by a multidisciplinary presurgical care clinic or the primary care physician.

Main Outcomes and Measures

The primary outcome was 365-day mortality after the elective surgical procedure. Secondary outcomes included 30-day and 180-day mortality as well as the proportion of patients referred for additional evaluation based on documented frailty.

Results

A total of 50 463 patients with at least 1 year of postsurgical follow-up (22 722 before intervention implementation and 27 741 after) were included (mean [SD] age, 56.7 [16.0] y; 57.6% women). Demographic characteristics, RAI score, and operative case mix, as defined by Operative Stress Score, were similar between time periods. After BPA implementation, the proportion of frail patients referred to a primary care physician and presurgical care clinic increased significantly (9.8% vs 24.6% and 1.3% vs 11.4%, respectively; both P < .001). Multivariable regression analysis demonstrated an 18% reduction in the odds of 1-year mortality (0.82; 95% CI, 0.72-0.92; P < .001). Interrupted time series models demonstrated a significant slope change in the rate of 365-day mortality from 0.12% in the preintervention period to -0.04% in the postintervention period. Among patients triggering the BPA, estimated 1-year mortality changed by -4.2% (95% CI, -6.0% to -2.4%).

Conclusions and Relevance

This quality improvement study found that implementation of an RAI-based FSI was associated with increased referrals of frail patients for enhanced presurgical evaluation. These referrals translated to a survival advantage among frail patients of similar magnitude to those observed in a Veterans Affairs health care setting, providing further evidence for both the effectiveness and generalizability of FSIs incorporating the RAI.

Chief Residents Can Safely Operate on Older and Frail Patients

INTRODUCTION

Older age and frailty increase the risk of poor recovery after surgery. We hypothesized that general surgery operations performed by supervised chief residents, as opposed to attending physicians, would still be safe for these vulnerable patients.

MATERIALS AND METHODS

We used the Veterans Affairs Surgical Quality Improvement Program database to identify 114,525 patients age 65+ y, including 18,030 patients age 80+ y and 47,555 categorized as frail, who had a general surgery procedure from 1999 to 2019 that was performed by an attending physician or by a supervised chief resident. Frailty was defined by a Risk Analysis Index score ≥30. We used inverse probability weighting on the propensity score to compare morbidity and mortality between operations performed by attendings versus chief residents.

RESULTS

Patients 65 y and above had a 2.1% increase in postoperative complications when the surgery was performed by a chief resident instead of an attending surgeon (95%CI 1.2%-3.0%, P < 0.0001). A similarly increased risk of complications was seen for patients age ≥80 y old (+2.3%, 95%CI 0.7%-3.9%, P = 0.004) and for frail patients (+2.7%, 95%CI 1.4%-4.0%, P < 0.0001). There were no differences in mortality for patients age 65+ y (+0.2%, 95%CI -0.1%-0.5%, P = 0.2), 80+ y (+0.3%, 95%CI -0.6%-1.1%, P = 0.5), or frail patients (+0.2%, 95%CI -0.5%-0.8%, P = 0.6) when their operations were performed by chief residents.

CONCLUSIONS

We found a small increase in morbidity and no difference in mortality when older or frail patients were operated on by chief residents rather than attending surgeons. Our findings suggest that it is reasonable and safe for training programs to allow appropriately supervised chief residents to operate on older or frail patients.

Study protocol for a pilot trial analysing the usability, validity and safety of an interventional health app programme for the structured prehabilitation of patients before major surgical interventions: the PROTEGO MAXIMA trial

INTRODUCTION

Major surgery is associated with a high risk for postoperative complications, leading to an increase in mortality and morbidity, particularly in frail patients with a reduced cardiopulmonary reserve. Prehabilitation, including aerobic exercise training, aims to improve patients' physical fitness before major surgery and reduce postoperative complications, length of hospital stay and costs. The purpose of the study is to assess the usability, validity and safety of an app-based endurance exercise software in accordance with the Medical Device Regulation using wrist-worn wearables to measure heart rate (HR) and distance.

METHODS AND ANALYSIS

The PROTEGO MAXIMA trial is a prospective, interventional study with patients undergoing major elective surgery, comprising three tasks. Tasks I and II aim to assess the usability of the app, using evaluation questionnaires and usability scenarios. In Task IIIa, patients will undergo a structured risk assessment by the Patronus App, which will be correlated with the occurrence of postoperative complications after 90 days (non-interventional). In Task IIIb, healthy students and patients will perform a supervised 6 min walking test and a 37 min interval training on a treadmill based on HR reserve, wearing standard ECG limb leads and two smartwatches, which will be driven by the test software. The aim of this task is to assess the accuracy of HR measurement by the wearables and the safety, using specific alarm settings of the devices and lab testing of the participants (interventional).

ETHICS AND DISSEMINATION

Ethical approval was granted by the Institutional Review Board of the University Hospital of Frankfurt and by the Federal Institute for Pharmaceuticals and Medical Products (BfArM, reference number 94.1.04-5660-13655) on 7 February 2022. The results from this study will be submitted to peer-reviewed journals and reported at suitable national and international meetings.

[Supporting the frail elderly: from resilience to reducing hospitalizations]

The frail elderly population will most certainly continue to grow in the coming years. Consequently, the number of hospitalizations and the iatrogenic dependence linked to them will increase. In this context, it seems interesting to question frailty. Indeed, accompanying, in ambulatory care, these patients towards a resilient behavior is one of the roles of advanced practice nurses, which it would be judicious to deepen in order to decrease the recourse to hospitalization.

The modified 5-item frailty index determines the length of hospital stay and accompanies with mortality rate in patients with bone and implant-associated infections after trauma and orthopedic surgery

BACKGROUND

Bone and implant-associated infections are severe complications after trauma and orthopedic surgery. The modified 5-item frailty index (mFI-5) is an easily applicable score to predict adverse outcome after surgery. The current literature regarding mFI-5 is focused on a period of 30-days postoperative.

PURPOSE

This study aims to assess the impact of frailty in orthopedic trauma patients with bone and implant-associated infections. mFI-5 was calculated from a database, which prospectively collects data about factors potentially correlated with peri- and postoperative complications since 2014.

METHODS

In a level I trauma center a total of 345 patients with surgical site infections were enrolled in this study. Hereof, patients with fracture-related infections after osteosynthesis, periprosthetic joint infections of the hip and knee and post-operative osteomyelitis were included. Extensive medical baseline examination was performed in 2013/14, a three-year follow-up was organized as a telephone interview. The mFI-5 score was calculated based on the 5 factor-principle as established by Subramaniam. The nutritional status was assessed using the Nutritional Risk Screening (NRS-2002).

RESULTS

130 patients were included, whereof seven had died, resulting in 123 patients. A grouping of our patients was performed in mFI-5 = 0 (n = 46; 36,4%), mFI-5 = 1 (n = 41; 33,3%) or mFI-5 ≥ 2 (n = 36; 29,3%). Sex distribution showed 69,1% male and 30,9% female patients. Frailty did neither impact on the re-admission (p = 0,433) nor the reoperation (p = 0,327) rate in our cohort. The mortality risk nearly doubled (1,7 times) in frail patients, but did not reach significance. In hospital stay was prolonged due to frailty (12,1 ± 11,8; p = 0,004) compared to those with a mFI-5 = 0 (5,9 ± 5,1) or mFI-5 = 1 (6,9 ± 5,9). Frailty goes along with a risk of malnutrition and increases with age.

CONCLUSION

The modified 5-item frailty index is not a suitable screening tool for predicting revision rate, re-admission rate, and mortality in our orthopedic trauma patient population with bone and implant-associated infections. Nevertheless, frailty is associated with an increased risk of malnutrition and increases with age.

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.

Microsurgical clipping and endovascular management of unruptured anterior circulation aneurysms: how age, frailty, and comorbidity indexes influence outcomes

OBJECTIVE

Frailty is one of the important factors in predicting the outcomes of surgery. Many surgical specialties have adopted a frailty assessment in the preoperative period for prognostication; however, there are limited data on the effects of frailty on the outcomes of cerebral aneurysms. The object of this study was to find the effect of frailty on the surgical outcomes of anterior circulation unruptured intracranial aneurysms (UIAs) and compare the frailty index with other comorbidity indexes.

METHODS

A retrospective study was performed utilizing the National Inpatient Sample (NIS) database (2016-2018). The Hospital Frailty Risk Score (HFRS) was used to assess frailty. On the basis of the HFRS, the whole cohort was divided into low-risk (0-5), intermediate-risk (> 5 to 15), and high-risk (> 15) frailty groups. The analyzed outcomes were nonhome discharge, complication rate, extended length of stay, and in-hospital mortality.

RESULTS

In total, 37,685 patients were included in the analysis, 5820 of whom had undergone open surgical clipping and 31,865 of whom had undergone endovascular management. Mean age was higher in the high-risk frailty group than in the low-risk group for both clipping (63 vs 55.4 years) and coiling (64.6 vs 57.9 years). The complication rate for open surgical clipping in the high-risk frailty group was 56.1% compared to 0.8% in the low-risk group. Similarly, for endovascular management, the complication rate was 60.6% in the high-risk group compared to 0.3% in the low-risk group. Nonhome discharges were more common in the high-risk group than in the low-risk group for both open clipping (87.8% vs 19.7%) and endovascular management (73.1% vs 4.4%). Mean hospital charges for clipping were $341,379 in the high-risk group compared to $116,892 in the low-risk group. Mean hospital charges for coiling were $392,861 in the high-risk frailty group and $125,336 in the low-risk group. Extended length of stay occurred more frequently in the high-risk frailty group than in the low-risk group for both clipping (82.9% vs 10.7%) and coiling (94.2% vs 12.7%). Frailty had higher area under the receiver operating characteristic curve values than those for other comorbidity indexes and age in predicting outcomes.

CONCLUSIONS

Frailty affects surgical outcomes significantly and outperforms age and other comorbidity indexes in predicting outcome. It is imperative to include frailty assessment in preoperative planning.

High Risk, High Reward: Frailty in Colorectal Cancer Surgery is Associated with Worse Postoperative Outcomes but Equivalent Long-Term Oncologic Outcomes

BACKGROUND

Frailty is a physiologic state that affects perioperative outcomes. Studies evaluating the impact of frailty on long-term oncologic outcomes are limited. This study evaluated perioperative and long-term oncologic outcomes for elderly patients undergoing colorectal surgery.

METHODS

Patients older than 65 years at the time of colorectal resection between July 2011 and September 2020 at Roswell Park Comprehensive Cancer Center were identified. Variables from the National Surgical Quality Improvement Program (NSQIP), the tumor registry, and electronic medical records (EMRs) were used to identify frail patients using the revised Risk Analysis Index (RAI-A) score. A score of 38 or higher defined a patient as "frail." Perioperative outcomes were evaluated using logistic regression and chi-square, and oncologic outcomes were evaluated using Kaplan-Meier analysis.

RESULTS

The study analyzed 411 patients. The mean age at surgery was 75.1 years. The median RAI-A score was 37, and 29.9 % of the patients were frail. The frail patients had significantly higher rates of overall complications (30.1 % vs 14.6 %; p < 0.001). They also had significantly higher rates of postoperative hospitalization longer than 30 days, postoperative delirium, and discharge to rehabilitation. No mortality differences were observed. The 318 patients with colorectal adenocarcinoma undergoing curative-intent resection were evaluated for oncologic outcomes. No differences with frailty in terms of overall survival, disease-specific survival, or progression-free survival were observed except for frail patients with stage 0 or 1 adenocarcinoma, who had worse overall survival than non-frail patients but equivalent other outcomes.

CONCLUSIONS

For elderly patients undergoing colorectal surgery, frailty is associated with higher postoperative complications, discharge to rehabitation, and prolonged hospitalization rates. Frailty does not affect long-term oncologic outcomes, so frail elderly patients gain the same oncologic benefit with surgery as non-frail patients.

Frailty Assessment and Perioperative Major Adverse Cardiovascular Events After Noncardiac Surgery

OBJECTIVE

Frailty is an emerging risk factor for adverse outcomes. However, perioperative frailty assessments derived from electronic health records have not been studied on a large scale. We aim to estimate the prevalence of frailty and the associated incidence of major adverse cardiovascular events (MACE) among adults hospitalized for noncardiac surgery.

METHODS

Adults aged ≥45 years hospitalized for noncardiac surgery from 2004-2014 were identified from the National Inpatient Sample. The validated Hospital Frailty Risk Score (HFRS) derived from International Classification of Diseases codes was used to classify patients as low (HFRS <5), medium (5-10), or high (>10) frailty risk. The primary outcome was MACE, defined as myocardial infarction, cardiac arrest, and in-hospital mortality. Multivariable logistic regression was used to estimate the adjusted odds of MACE stratified by age and HFRS.

RESULTS

A total of 55,349,978 hospitalizations were identified, of which 81.0%, 14.4%, and 4.6% had low, medium, and high HFRS, respectively. Patients with higher HFRS had more cardiovascular risk factors and comorbidities. MACE occurred during 2.5% of surgical hospitalizations and was common among patients with high frailty scores (high HFRS: 9.1%, medium: 6.9%, low: 1.3%, P < .001). Medium (adjusted odds ratio [aOR] 2.05; 95% confidence interval [CI], 2.02-2.08) and high (aOR 2.75; 95% CI, 2.70-2.79) HFRS were associated with greater odds of MACE vs low HFRS, with the greatest odds of MACE observed in younger individuals 45-64 years (interaction P value < .001).

CONCLUSIONS

The HFRS may identify frail surgical inpatients at risk for adverse perioperative cardiovascular outcomes.

Is surgical resection predict overall survival in frail patients with glioblastoma, IDH-wildtype?

PURPOSE

We assessed the impact of frailty on surgical outcomes, survival, and functional dependency in elderly patients harboring a glioblastoma, isocitrate dehydrogenase (IDH)-wildtype.

METHODS

We retrospectively reviewed records of old and frail patients surgical treated at a single neurosurgical institution between January 2018 to May 2021. Inclusion criteria were: (1) neuropathological diagnosis of glioblastoma, IDH-wildtype; (2) patient≥65years at the time of surgery; (3) available data to assess the frailty index according to the 5-modified Frailty Index (5-mFI).

RESULTS

A total of 47 patients were included. The 5-mFI was at 0 in 11 cases (23.4%), at 1 in 30 cases (63.8%), at 2 in two cases (4.2%), at 3 in two cases (4.2%), and at 4 in two cases (4.2%). A gross total resection was performed in 26 patients (55.3%), a subtotal resection was performed in 13 patients (27.6%), and a biopsy was performed in 8 patients (17.1%). The rate of 30-day postoperative complications was higher in the biopsy subgroup and in the 5-mFI=4 subgroup. Gross total resection and age≤70years were independent predictors of a longer overall survival. Sex, 5-mFI, postoperative complications, and preoperative Karnofsky Performance Status score did not influence overall survival and functional dependency.

CONCLUSION

In patients≥65years harboring a glioblastoma, IDH-wildtype, gross total resection remains an independent predictor of longer survival and good postoperative functional recovery. The frailty, assessed by the 5-mFI score, does not influence surgery and outcomes in this dataset. Further confirmatory analyses are required.

A systematic review of perioperative clinical practice guidelines for care of older adults living with frailty

BACKGROUND

Perioperative frailty is prevalent and requires complex management, which could be guided by clinical practice guidelines (CPGs). The objective of this systematic review was to identify and synthesise CPGs that provide perioperative recommendations specific to older adults living with frailty.

METHODS

After protocol registration, we performed a systematic review of CPGs. MEDLINE, Embase, CINAHL, and 14 grey literature databases were searched (January 1, 2000 until December 22, 2021). We included all CPGs that contained at least one frailty-specific recommendation related to any phase of the perioperative period. We compiled all relevant recommendations, extracted underlying strength of evidence, and categorised them by perioperative phase of care. Within each phase, recommendations were synthesised inductively into themes. Quality of CPGs was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.

RESULTS

From 4707 citations, 13 guidelines were included; 8/13 were focused on the perioperative care of older surgical patients in general. Among 110 recommendations extracted, 37 themes were generated, with the majority pertaining to preoperative care. Four themes were supported by strong evidence: performing preoperative frailty assessments, using multidimensional frailty instruments, reducing urinary catheter use, and following multidisciplinary care and communication throughout the perioperative period. Per AGREE II, most guidelines (8/13; 62%) were recommended for use with modifications.

CONCLUSIONS

Despite increasing numbers of patients living with frailty, few guidelines exist that address frailty-specific perioperative care. Given the lack of strong evidence-based recommendations, particularly outside the preoperative period, high-quality primary research is required to underpin future guidelines and better inform the care of older surgical patients with frailty.

Delirium Prevention and Management in Frail Surgical Patients

Delirium, an acute, fluctuating impairment in cognition and awareness, is one of the most common causes of postoperative brain dysfunction. It is associated with increased hospital length of stay, health care costs, and mortality. There is no FDA-approved treatment of delirium, and management relies on symptomatic control. Several preventative techniques have been proposed, including the choice of anesthetic agent, preoperative testing, and intraoperative monitoring. Frailty, a state of increased vulnerability to adverse events, is an independent and potentially modifiable risk factor for the development of delirium. Diligent preoperative screening techniques and implementation of prevention strategies could help improve outcomes in high-risk patients.

Listing Dilemmas: Age, Frailty, Weight, Preexisting Cancers, and Systemic Diseases

Selection of lung transplant candidates is an evolving field that pushes the boundaries of what is considered the norm. Given the continually changing demographics of the typical lung transplant recipient as well as the growing list of risk factors that predispose patients to poor posttransplant outcomes, we explore the dilemmas in lung transplant candidate selections pertaining to older age, frailty, low and high body mass index, preexisting cancers, and systemic autoimmune rheumatic diseases.

Modified frailty index as an indicator for outcomes after lower extremity endovascular revascularization

BACKGROUND

The 5-factor frailty index is associated with adverse outcomes after various procedures. This study aimed to evaluate the performance of the 5-factor frailty index after lower extremity endovascular revascularization.

METHODS

The American College of Surgeons' National Surgical Quality Improvement Program Database as retrospectively analyzed for patients undergoing lower extremity endovascular revascularization between 2015 and 2019. Outcomes were assessed using bivariate analyses and multivariate logistic regression analyses.

RESULTS

In the study, 11,947 lower extremity endovascular revascularization performed between 2015 and 2019 were identified from National Surgical Quality Improvement Program Database. Median age was 69 (standard deviation 11.44) years, 4,727 (39.6%) were female, and 7,570 (63.4%) were White. In addition, 7,541 (62.9%) were performed for chronic limb threatening ischemia. Thirty-day mortality was 1.7%. Bivariate analysis demonstrated that a 5-factor frailty index score greater than 0.6 was associated with higher rates of discharge to SNF (28.6% vs 8.2%, P < .001, reference 5-factor frailty index = 0), cardiopulmonary arrest (2.0% vs 0.1%, P < .001), readmission (21.1% vs 10.8%, P < .001), reintubation (2.8% vs 0.3%, P < .001), and 30-day mortality (5.1% vs 0.7%, P < .001). Beta blocker use, higher age, chronic limb threatening ischemia indication, and 5-factor frailty index were all associated with increased 30-day mortality. Multivariate logistic regression showed that 5-factor frailty index >0.6 predicted 3 times higher odds for 30-day mortality (odds ratio, 2.988; P = .013), with physiologic high risk (odds ratio, 2.118; P < .001), chronic limb threatening ischemia indication (odds ratio, 2.157; P < .001), and inpatient procedures (odds ratio, 3.409; P < .001) also showing increased risk for mortality.

CONCLUSION

For patients undergoing lower extremity endovascular revascularization, higher 5-factor frailty index was associated with increased hospital resource utilization and 30-day mortality. The 5-factor frailty index may be useful for preoperative risk stratification and predicting adverse outcomes in patients undergoing lower extremity endovascular revascularization.

Association Between the Modified Frailty Index and Outcomes Following Lobectomy

INTRODUCTION

Elective thoracic surgery is safe in well-selected elderly patients. The association of frailty with postoperative morbidity in elective-lobectomy patients is understudied. We examined frailty as defined by abbreviated modified frailty index (mFI-5), mFI-11 in the thoracic surgery population, and the correlation between frailty and postoperative complications.

METHODS

We studied outcomes of patients in two cohorts, 2010-2012 and 2013-2019, from the National Surgical Quality Improvement Program (NSQIP) database and used multivariable logistic regression models to predict all postoperative morbidity, mortality, and major morbidity. The mFI-5 could be calculated for all subjects (both 2010-2012, and 2013-2019); the mFI-11 could only be calculated for the 2010-2012 cohort. Patient frailty was defined as mFI≥3 (with either index). We used odds ratios (ORs) to examine associations of preoperative characteristics with postoperative complications and C-statistics to assess overall predictive power.

RESULTS

Complications were less prevalent in the 2013-2019 cohort (17.9% versus 19.5%, P = 0.008). Open lobectomies were more common in the 2010-2012 cohort (53.9% versus 34.6%) and were strongly associated with postoperative morbidity and mortality (ORs >1.5) in both cohorts. Each frailty measure was associated with morbidity and mortality (ORs >1.4) after adjusting for other significant preoperative factors. Models on the 2010-2012 cohort had nearly identical C-statistics using the mFI-11 versus mFI-5 frailty indices (0.6142 versus 0.6139; P > 0.8).

CONCLUSIONS

Frailty, as captured in the mFI-5, is a significant associated factor of postoperative morbidity and mortality following elective lobectomies. As a modifiable risk factor, frailty should be considered in surgical decision-making and when counseling patients regarding perioperative risks.
