Too Frail for Surgery? Initial Results of a Large Multidisciplinary Prospective Study Examining Preoperative Variables Predictive of Poor Surgical Outcomes

Frailty as a predictor of adverse outcomes in patients with hepatectomy - the importance of design studies to improve frailty: A systematic review and meta-analysis of 128 868 patients

BACKGROUND

Frailty has been associated with increased mortality among patients with surgery. However, evidence about the frailty prevalence and outcomes in frail populations with hepatectomy is inconsistent and has not been clarified. The purpose of this study was to quantitatively synthesize the prevalence of frailty and the role of frailty on mortality in patients with hepatectomy.

METHODS

Embase, PubMed, Scopus, and Web of Science were searched for eligible studies that explored the prevalence and impact of frailty in hepatectomy from inception until January 24, 2024. The pooled prevalence of frailty and odds ratio (OR) corresponding 95% confidence intervals (CI) in mortality and major complications estimates were analyzed.

RESULTS

A total of 26 studies containing 128 868 patients with hepatectomy were included. The prevalence of frailty in hepatectomy was 23% (95% CI: 17-28; p = .000). Frailty was associated with an increased odds ratio for mortality (adjusted OR = 3.06; 95% CI: 1.85-5.04; p = .000). Furthermore, frailty was significantly associated with an increased odds ratio for major complications (adjusted OR = 3.20; 95% CI: 2.04-5.04; p < .01).

CONCLUSION

The prevalence of frailty in patients with hepatectomy is prevalent, which has a significant adverse impact on the outcomes of patients with hepatectomy. These findings highlight the importance of frailty assessment in this population, which may provide prognostic details.

Outcomes following pancreaticoduodenectomy for octogenarians: a systematic review and meta-analysis

BACKGROUND

An increasing number of elderly patients are being diagnosed with pancreatic cancer, with increasing need to consider pancreatic surgery. This study aims to provide an updated systematic review and meta-analysis to evaluate the outcomes following pancreaticoduodenectomy in octogenarians.

METHODS

A systematic review and meta-analysis was performed via a search of Medline, PubMed and Cochrane databases. Studies comparing outcomes of patients >80 years to younger patients undergoing PD were included.

RESULTS

26 studies were included. This included 22481 patients, with 20134 (89.6%) aged <80 years old, and 2347 (10.4%) octogenarians. Octogenarians were associated with higher rates of mortality (OR 2.37 (95%CI 1.91-2.94, p < 0.00001)), all-cause morbidity (OR 1.60 (95%CI 1.30-1.96), p<0.00001) and re-operation (OR 1.41 (95%CI 1.13-1.75), p = 0.002). Octogenarians had a two-fold risk of cardiac complications and respiratory complications (OR 2.13 (95%CI 1.67-2.73), p < 0.00001), (OR 2.38 (95%CI 1.72-3.27), p < 0.0001). There was no difference in postoperative pancreatic fistula, post-pancreatectomy hemorrhage or delayed gastric emptying. Younger patients were more likely to return to adjuvant therapy (OR 0.20 (95%CI 0.12-0.34), p < 0.00001).

CONCLUSIONS

Octogenerians are associated with higher mortality rate, postoperative complications, and reduced likelihood to undergo adjuvant therapy. Careful preoperative assessment and selection of elderly patients for consideration of pancreatic surgery is essential.

Adoption of robot-assisted radical nephroureterectomy permits a minimally invasive option for management of upper tract urothelial carcinoma in geriatric patients: comparison with non-geriatric patients with intermediate-term oncologic follow-up

To assess the oncologic efficacy and safety of robot-assisted approach to radical nephroureterectomy (RARNU) in geriatric versus younger patients with upper tract urothelial carcinoma (UTUC). A single-center, retrospective cohort study was conducted from 2009 to 2022 of 145 patients (two cohorts: < 75 and ≥ 75 years old) with non-metastatic UTUC who underwent RARNU. Primary endpoint was UTUC-related recurrence of disease during surveillance (bladder-specific and metastatic). Safety was assessed according to 30-day, modified Clavien-Dindo (CD) classifications (Major: C.D. III-V). Survival estimates were performed using Kaplan-Meier method. There were 89 patients < 75 years (median 65 years) and 56 patients ≥ 75 years (median 81 years). Comparing the young versus geriatric cohorts: median follow-up 38 vs 24 months (p = 0.03, respectively) with similar 3-year bladder-specific recurrence survival (60% vs 67%, HR 0.70, 95% CI [0.35, 1.40], p = 0.31) and metastasis-free survival (79% vs 70%, HR 0.71, 95% CI [0.30, 1.70], p = 0.44). Expectedly, the younger cohort had a significant deviation in overall survival compared to the geriatric cohort at 1-year (89% vs 76%) and 3-years (72% vs 41%; HR 3.29, 95% CI [1.88, 5.78], p < 0.01). The 30-day major (1% vs 0) and minor complications (8% vs 14%, p = 0.87). Limitations include retrospective study design of a high-volume, single-surgeon experience. Compared to younger patients with UTUC, geriatric patients undergoing RARNU have similar oncologic outcomes at intermediate-term follow-up with no increased risk of 30-day perioperative complications. Thus, age alone should not be used to disqualify patients from definitive surgical management of UTUC with RARNU.

Differences in preoperative frailty assessment of surgical candidates by sex, age, and race

Introduction

Surgical decision-making often relies on a surgeon's subjective assessment of a patient's frailty status to undergo surgery. Certain patient demographics can influence subjective judgment when compared to validated objective assessments. In this study, we explore the relationship between subjective and objective frailty assessments according to patient age, sex, and race.

Methods

Patients were prospectively enrolled in urology, general surgery, and surgical oncology clinics. Using a visual analog scale (0-100), operating surgeons independently rated the patient's frailty status. Objective frailty was classified using the Fried Frailty Criteria ranging from 0 to 5. Multivariable proportional odds models were conducted to examine the potential association of factors with objective frailty, according to surgeon frailty rating. Subgroup analysis according to patient sex, race, and age was also performed.

Results

Seven male surgeons assessed 203 patients preoperatively with a median age of 65. A majority of patients were male (61 %), white (67 %), and 60 % and 40 % underwent urologic and general surgery/surgical oncology procedures respectively. Increased subjective surgeon rating (OR 1.69; p < 0.001) was significantly associated with the presence of objective frailty. On subgroup analysis, a higher magnitude of such association was observed more in females (OR 1.86; p = 0.0007), non-white (OR 1.84; p = 0.0019), and older (>60, OR 1.75; p = 0.0001) patients, compared to male (OR 1.45; p = 0.0243), non-white (OR 1.48; p = 0.0109) and patients under 60 (OR 1.47; p = 0.0823).

Conclusion

The surgeon's subjective assessment of frailty demonstrated tendencies to rate older, female, and non-white patients as frail; however, differences in patient sex, age, and race were not statistically significant.

Preoperative diagnosis of frailty

The aging world population obliges physicians to establish measures to optimize and estimate the outcomes of increasingly frail patients. Thus, in the last few years there has been an increase in the application of frailty indices. Multiple scales have emerged that can be applied in the perioperative setting. Each one has demonstrated some utility, either by way of establishing postoperative prognosis or as a method for the clinical optimization of patient care. Anaesthesiologists are offered a wide choice of scales, the characteristics and appropriate management of which they are often unaware. This narrative review aims to clarify the concept of frailty, describe its importance in the perioperative setting and evaluate the different scales that are most applicable to the perioperative setting. It will also establish paths for the future optimization of patient care.

Association between frailty and clinical outcomes in patients undergoing craniotomy-systematic review and meta-analysis of observational studies

BACKGROUND

Frailty in patients undergoing craniotomy may affect perioperative outcomes. There have been a number of studies published in this field; however, evidence is yet to be summarized in a quantitative review format. We conducted a systematic review and meta-analysis to examine the effects of frailty on perioperative outcomes in patients undergoing craniotomy surgery.

METHODS

Our eligibility criteria included adult patients undergoing open cranial surgery. We searched MEDLINE via Ovid SP, EMBASE via Ovid SP, Cochrane Library, and grey literature. We included retrospective and prospective observational studies. Our primary outcome was a composite of complications as per the Clavien-Dindo classification system. We utilized a random-effects model of meta-analysis. We conducted three preplanned subgroup analyses: patients undergoing cranial surgery for tumor surgery only, patients undergoing non-tumor surgery, and patients older than 65 undergoing cranial surgery. We explored sources of heterogeneity through a sensitivity analysis and post hoc analysis.

RESULTS

In this review of 63,159 patients, the pooled prevalence of frailty was 46%. The odds ratio of any Clavien-Dindo grade 1-4 complication developing in frail patients compared to non-frail patients was 2.01 [1.90-2.14], with no identifiable heterogeneity and a moderate level of evidence. As per GradePro evidence grading methods, there was low-quality evidence for patients being discharged to a location other than home, length of stay, and increased mortality in frail patients.

CONCLUSION

Increased frailty was associated with increased odds of any Clavien-Dindo 1-4 complication. Frailty measurements may be used as an integral component of risk-assessment strategies to improve the quality and value of neurosurgical care for patients undergoing craniotomy surgery.

ETHICS AND DISSEMINATION

Five-factors Modified Frailty Index role as predictors of outcomes after proximal abdominal aortic aneurysms

BACKGROUND

The aim of the study was to evaluate the correlation between frailty, measured by the Five-Factor Modified Frailty Index (mFI-5) and mortality and all major adverse events (MAE) in patients who underwent proximal abdominal aortic aneurysm (p-AAA) open surgery (OS).

METHODS

Data of all elective patients submitted to p-AAA OS from 2010 to 2021 were recorded. Primary endpoints were 30-day mortality and mid-term survival and secondary endpoints included postoperative acute kidney injury (AKI), freedom from aortic reintervention and any MAE. The impact of frailty was assessed by univariate and multivariate analysis; mid-term overall survival were estimated using Kaplan-Meier method (log-rank test).

RESULTS

Two-hundred twenty-one patients (197 male, 24 female; aged 72.2±7.4) were included. Thirty-seven (16.4%) were octogenarians (>80 years). The mFI-5 was assessed in the entire group: mean mFI-5 was 0.29±0.12. One-hundred patients (100/221, 45.25%, 91:9 male-to-female ratio) were defined "frail" considering the mFI-5 cut-off >0.25. At univariate analysis a correlation was found between mFI-5>0.25 and mid-term mortality (Pearson correlation [r] 0.280, P<0.001) and AKI (r=0.146, P=0.030). No correlation with 30-day mortality was found (P not significant). At multivariate analysis mFI-5>0.25 increased the risk for midterm mortality (odds ratio 3.32, P=0.021) and postoperative AKI (OR 2.09, P<0.001). The effect of mFI-5>0.25 on mid-term mortality persisted after adjustment for age (P<0.001). Survival was estimated with Kaplan-Meyer method (mean follow-up of 52.7 months, 95% CI: 48.6-56.8); 68 (30.7%) deaths were recorded: 23 among non-frail patients (19.0%) and 45 among frail patients (45/100, 45%, P<0.001).

CONCLUSIONS

These findings suggest that mFI-5 is a tool capable to identify "frail" patients, who appear to be at increased risk of postoperative AKI and mid-term mortality, but not 30-day mortality. Five-factor modified Frailty Index assessment is simple, fast and can be widely applied in surgical practice to perform appropriate risk stratifications.

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.

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.

Psoas attenuation and cross-sectional area improve performance of traditional sarcopenia measurements in predicting one-year mortality among elderly patients undergoing emergency abdominal surgery: a pilot study of five computed tomography techniques

BACKGROUND

Risk stratification is challenging in the growing population of geriatric patients requiring emergency surgery. Sarcopenia, which assesses muscle bulk, is a surrogate for frailty and predicts 1-year mortality, but does not incorporate potentially valuable additional information about muscle quality.

OBJECTIVE

To describe five different CT methods of measuring sarcopenia and muscle quality and to determine which method has the greatest sensitivity for predicting 1-year mortality following emergency abdominal surgery in elderly patients.

METHODS

This retrospective study includes 297 patients 70 years and older who underwent "urgent" or "emergent" laparotomy or laparoscopy for acute abdominal disease between 2006 and 2011 at a single quaternary academic medical center. All patients received a CT abdomen and pelvis with intravenous contrast within 1 month of surgery. Five different methods were applied to the psoas muscles on CT: method 1 (total psoas index TPI, which is total psoas area TPA normalized by height), method 2 ("pseudoarea" = anterior-posterior × transverse dimensions), method 3 (average HU), method 4 (TPA × HU), and method 5 ("pseudoarea" × HU).

RESULTS

For all five CT measures, mortality was greatest for the lowest quartile by univariate and adjusted Cox proportional hazard analyses at all time points up to 1-year. The C-statistic was highest for Method 4, using a composite index of TPA and Hounsfield Units, indicating the greatest predictive ability to estimate mortality at all time points.

CONCLUSION

Muscle quality and muscle size can be used in tandem to refine risk assessment of older patients undergoing emergency abdominal surgery. Routine calculation of the composite score of psoas cross-sectional area and HU in the emergency room setting may provide surgeons and patients valuable insight on the risk of 1-year mortality to guide preoperative decision-making and counseling.

CLINICAL IMPACT

Muscle quality and size, both strong independent predictors of surgical outcomes in older patients undergoing emergency abdominal surgery, may be used in tandem to refine risk assessment. A composite score of psoas muscle cross-sectional area and Hounsfield units on CT may provide insight on 1-year mortality in this patient population.

Frailty as a predictor of neurosurgical outcomes in brain tumor patients: A systematic review and meta-analysis

BACKGROUND

Patients with frailty are at a high risk of poor health outcomes, and frailty has been explored as a predictor of adverse events, such as perioperative complications, readmissions, falls, disability, and mortality in the neurosurgical literature. However, the precise relationship between frailty and neurosurgical outcomes in patients with brain tumor has not been established, and thus evidence-based advancements in neurosurgical management. The objectives of this study are to describe existing evidence and conduct the first systematic review and meta-analysis of the relationship between frailty and neurosurgical outcomes among brain tumor patients.

METHODS

Seven English databases and four Chinese databases were searched to identify neurosurgical outcomes and the prevalence of frailty among patients with a brain tumor, with no restrictions on the publication period. According to the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis and the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines, two independent reviewers employed the Newcastle-Ottawa scale in cohort studies and JBI Critical Appraisal Checklist for Cross-sectional Studies to evaluate the methodological quality of each study. Then random-effects or fixed-effects meta-analysis was used in combining odds ratio (OR) or hazard ratio (RR) for the categorical data and continuous data of neurosurgical outcomes. The primary outcomes are mortality and postoperative complications, and secondary outcomes include readmission, discharge disposition, length of stay (LOS), and hospitalization costs.

RESULTS

A total of 13 papers were included in the systematic review, and the prevalence of frailty ranged from 1.48 to 57%. Frailty was significantly associated with increased risk of mortality (OR = 1.63; CI = 1.33-1.98; p < 0.001), postoperative complications (OR = 1.48; CI = 1.40-1.55; p < 0.001; I ² = 33%), nonroutine discharge disposition to a facility other than home (OR = 1.72; CI = 1.41-2.11; p < 0.001), prolonged LOS (OR = 1.25; CI = 1.09-1.43; p = 0.001), and high hospitalization costs among brain tumor patients. However, frailty was not independently associated with readmission (OR = 0.99; CI = 0.96-1.03; p = 0.74).

CONCLUSION

Frailty is an independent predictor of mortality, postoperative complications, nonroutine discharge disposition, LOS, and hospitalization costs among brain tumor patients. In addition, frailty plays a significant potential role in risk stratification, preoperative shared decision making, and perioperative management.

Evaluating the Impact of Preoperative Geriatric-Specific Variables and Modified Frailty Index on Postoperative Outcomes After Elective Pancreatic Surgery

BACKGROUND

Pursuing pancreatic resection in elderly patients is often complex and limited by concern for functional status and postoperative risk. This study examines the associations between two different preoperative functional status metrics with postoperative outcomes in the geriatric population.

METHODS

Patients who participated in the ACS NSQIP Geriatric Surgery Research File pilot program (2014-2018) undergoing elective pancreatic operations were included. Two clinically meaningful functional status scores were calculated: the presence of one or more geriatric-specific variable (GSV) and a 5-factor modified frailty index (mFI-5). Multivariable logistic regression adjusting for ACS NSQIP-estimated risk was performed to evaluate associations between preoperative GSV, mFI-5 and 30-day outcome measures.

RESULTS

A total of 1266 patients were included: 808 (64%) age 65-74, 302 (24%) age 75-80, and 156 (12%) age ≥ 81; 843 (67%) patients underwent pancreatoduodenectomy. Operations were performed for pancreatic adenocarcinoma in 712 (56%) patients. Older patients had greater likelihood of postoperative morbidity (35% vs 31% vs 47%, by age group, p = 0.004) and discharge to a facility (12% vs 23% vs 48%, by age group, p < 0.001). Adjusting for ACS NSQIP predicted risk, patients with a preoperative GSV were more likely to require reoperation and discharge to a facility (OR 1.81 [95% CI 1.03-3.16] and 3.95 [95% CI 2.91-5.38], respectively). The mFI-5 was not associated with postoperative outcomes (all p ≥ 0.18).

CONCLUSION

The presence of a preoperative GSV is associated with reoperation and discharge to a skilled facility following elective pancreatic resection. Geriatric-specific variables should be considered in joint preoperative decision making to optimize care.

Outcomes After Major Surgical Procedures in Octogenarians: A Nationwide Cohort Study

Introduction

Aging of the worldwide population has been observed, and postoperative outcomes could be worse in elderly patients. This nationwide study assessed trends in number of surgical resections in octogenarians regarding various major surgical procedures and associated postoperative outcomes.

Methods

All patients who underwent surgery between 2014 and 2018 were included from Dutch nationwide quality registries regarding esophageal, stomach, pancreas, colorectal liver metastases, colorectal cancer, lung cancer and abdominal aortic aneurysms (AAA). For each quality registry, the number of patients who were 80 years or older (octogenarians) was calculated per year. Postoperative outcomes were length of stay (LOS), 30 day major morbidity and 30 day mortality between octogenarians and younger patients.

Results

No increase in absolute number and proportion of octogenarians that underwent surgery was observed. Median LOS was higher in octogenarians who underwent surgery for colorectal cancer, colorectal liver metastases, lung cancer, pancreatic disease and esophageal cancer. 30 day major morbidity was higher in octogenarians who underwent surgery for colon cancer, esophageal cancer and elective AAA-repair. 30 day mortality was higher in octogenarians who underwent surgery for colorectal cancer, lung cancer, stomach cancer, pancreatic disease, esophageal cancer and elective AAA-repair. Median LOS decreased between 2014 and 2018 in octogenarians who underwent surgery for stomach cancer and colorectal cancer. 30 day major morbidity decreased between 2014 and 2018 in octogenarians who underwent surgery for colon cancer. No trends were observed in octogenarians regarding 30 day mortality between 2014 and 2018.

Conclusion

No increase over time in absolute number and proportion of octogenarians that underwent major surgery was observed in the Netherlands. Postoperative outcomes were worse in octogenarians.

Venous Thromboembolism in Surgically Treated Esophageal Cancer Patients: A Provincial Population-Based Study

Objective  Venous thromboembolism (VTE) is a major cause of morbidity and mortality in surgical patients. Surgery for esophageal cancer carries a high risk of VTE. This study identifies the risk factors and associated mortality of thrombotic complications among patients undergoing esophageal cancer surgery.

Methods  All patients in the province of Ontario undergoing esophageal cancer surgery from 2007 to 2017 were identified. Logistic regression identified VTE risk factors at 90 days and 1 year postoperatively. A flexible parametric survival analysis compared mortality and survival up to 5 years after surgery for patients with and without a postoperative VTE.

Results  Overall 9,876 patients with esophageal cancer were identified; 2,536 (25.7%) underwent surgery. VTE incidence at 90 days and 1 year postoperatively were 4.1 and 6.3%, respectively. Patient factors including age, sex, performance status, and comorbidities were not associated with VTE risk. VTE risk peaked at 1 month after surgery, with a subsequent decline, plateauing after 6 months. Adenocarcinoma was strongly associated with VTE risk compared with squamous cell carcinoma (SCC) (odds ratio [OR] 2.53, 95% confidence interval [CI] 1.38–4.63, p  = 0.003). VTE risk decreased with adjuvant chemotherapy (OR = 0.58, 95% CI 0.36–0.94, p  = 0.028). Postoperative VTE was associated with decreased survival at 1 and 5 years (hazard ratio = 1.57, 95% CI 1.23–2.00, p  < 0.001).

Conclusion  Esophageal cancer patients with postoperative VTE have worse long-term survival compared with those without thrombotic complications. Adenocarcinoma carries a higher VTE risk compared with SCC. Strategies to reduce VTE risk should be considered to reduce the negative impacts on survival conferred by thrombotic events.

Clinical Factors and Outcomes When Real-World Heart Teams Overruled STS Risk Scores in TAVR Cases

Objectives

This study was conducted to determine why heart teams recommended transcatheter aortic valve replacement (TAVR) versus surgical AVR (SAVR) for patients at low predicted risk of mortality (PROM) and describe outcomes of these cases.

Background

Historically, referral to TAVR was based predominately on the Society of Thoracic Surgeons (STS) risk model's PROM >3%. In selected cases, heart teams had latitude to overrule these scores. The clinical reasons and outcomes for these cases are unclear.

Methods

Retrospective data were gathered for all TAVR and SAVR cases conducted by 9 hospitals between 2013 and 2017.

Results

Cases included TAVR patients with STS PROM >3% (n = 2,711) and ≤3% (n = 415) and SAVR with STS PROM ≤3% (n = 1,438). Leading reasons for recommending TAVR in the PROM ≤3% group were frailty (57%), hostile chest (22%), severe lung disease (16%), and morbid obesity (13%), and 44% of cases had multiple reasons. Most postoperative and 30-day outcomes were similar between TAVR groups, but the STS PROM ≤3% group had a one-day shorter length of stay (2.5 ± 3.4 vs. 3.5 ± 4.7 days; p ≤ 0.001) and higher one-year survival (91.6% vs. 86.0%, p=0.002). In patients with STS PROM ≤3%, 30-day mortality was higher for TAVR versus SAVR (2.0% vs. 0.6%; p < 0.001).

Conclusions

Heart teams recommended TAVR in patients with STS PROM ≤3% primarily due to frailty, hostile chest, severe lung disease, and/or morbid obesity. Similar postoperative outcomes between these patients and those with STS PROM >3% suggest that decisions to overrule STS PROM ≤3% were merited and may have reduced SAVR 30-day mortality rate.

Analysis of readmissions data among frail and non-frail patients presenting for acoustic neuroma

The incidence of acoustic neuromas in the United States is 1.09 per 100,000 with 23,739 newly diagnosed cases in the years 2004 to 2010. Because the recent literature has supported that frailty can serve as a more accurate predictor of patient outcomes when evaluated with age, and is an important variable to consider in the course of patient treatment. The objective of this study was to compare the outcomes of frail patients who had undergone surgery for acoustic neuroma with their non-frail counterparts.The authors conducted a retrospective cohort study of geriatric patients receiving cranial neurosurgery for acoustic neuroma between 2016 and 2017 by using the Nationwide Readmission Database. A total of 396 frail patients and 402 non-frail patients were identified through the database of undergoing surgery for acoustic neuroma. Frail patients had statistically higher rates of readmission (p < 0.01), post-operative infection (p < 0.01), facial paralysis (p < 0.01), urinary tract infection (p < 0.01), hydrocephalus (p < 0.01), and dysphagia (p < 0.01). These post-op morbidities likely led to the increased length of stay (p < 0.01), non-routine discharge (p < 0.01), and all payer cost seen in frail patients (p < 0.01). However, no significant difference was found between frail and non-frail patients with regards to CSF leak, post hemorrhagic anemia, myocardial infarction, and mortality. Patient frailty status is a significant predictor of poor outcomes in the postoperative sequelae of acoustic neuroma surgery. Further, models including patient frailty plus age outperformed those using age alone for prediction of several postoperative complications.

Benefits of both physical assessment and electronic health record review to assess frailty prior to heart transplant

INTRODUCTION

Frailty status affects outcomes after heart transplantation, but the optimal way to assess frailty prior to transplant remains unknown.

METHODS

This single-center, observational study assessed 44 heart transplant candidates for frailty using three methods. The Short Physical Performance Battery (SPPB) and Fried Frailty Phenotype (FFP) were used as two physical assessments of frailty. The Frailty Risk Score (FRS) was used as a chart-review based assessment measuring 20 different biopsychosocial and functional components, including biomarkers, depression, cognitive impairment, and sleep.

RESULTS

We determined the correlation between FRS, SPPB, and FFP and how each correlated with clinical outcomes. Of 44 participants, mean age was 60 years. FRS correlated with SPPB and FFP (P = .043, P < .001, respectively). Higher frailty as measured by SPPB and FRS was significantly associated with lack of achieving waitlist status (P = .022; P = .002) and not being transplanted (P = .026; P = .008). Higher frailty by SPPB and FFP was also associated with mortality (P = .010; P = .025).

CONCLUSION

SPPB and chart-review FRS showed potential for predicting waitlist and transplant status of heart transplant candidates, while SPPB and FFP were associated with mortality. Additional studies may serve to validate these observations.

How aging of the global population is changing oncology

Population aging is causing a demographic redistribution with implications for the future of healthcare. How will this affect oncology? First, there will be an overall rise in cancer affecting older adults, even though age-specific cancer incidences continue to fall due to better prevention. Second, there will be a wider spectrum of health functionality in this expanding cohort of older adults, with differences between “physiologically older” and “physiologically younger” patients becoming more important for optimal treatment selection. Third, greater teamwork with supportive care, geriatric, mental health and rehabilitation experts will come to enrich oncologic decision-making by making it less formulaic than it is at present. Success in this transition to a more nuanced professional mindset will depend in part on the development of user-friendly computational tools that can integrate a complex mix of quantitative and qualitative inputs from evidence-based medicine, functional and cognitive assessments, and the personal priorities of older adults.

A Clinical Decision Aid to Support Personalized Treatment Selection for Patients with Clinical T1 Renal Masses: Results from a Multi-institutional Competing-risks Analysis

BACKGROUND

Personalized treatment for clinical T1 renal cortical masses (RCMs) should take into account competing risks related to tumor and patient characteristics.

OBJECTIVE

To develop treatment-specific prediction models for cancer-specific mortality (CSM), other-cause mortality (OCM), and 90-d Clavien grade ≥3 complications across radical nephrectomy (RN), partial nephrectomy (PN), thermal ablation (TA), and active surveillance (AS).

DESIGN, SETTING, AND PARTICIPANTS

Pretreatment clinical and radiological features were collected for consecutive adult patients treated with initial RN, PN, TA, or AS for RCMs at four high-volume referral centers (2000-2019).

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Prediction models used competing-risks regression for CSM and OCM and logistic regression for 90-d Clavien grade ≥3 complications. Performance was assessed using bootstrap validation.

RESULTS AND LIMITATIONS

The cohort comprised 5300 patients treated with RN (n = 1277), PN (n = 2967), TA (n = 476), or AS (n = 580). Over median follow-up of 5.2 yr (interquartile range 2.5-8.7), there were 117 CSM, 607 OCM, and 198 complication events. The C index for the predictive models was 0.80 for CSM, 0.77 for OCM, and 0.64 for complications. Predictions from the fitted models are provided in an online calculator (https://small-renal-mass-risk-calculator.fredhutch.org). To illustrate, a hypothetical 74-yr-old male with a 4.5-cm RCM, body mass index of 32 kg/m², estimated glomerular filtration rate of 50 ml/min, Eastern Cooperative Oncology Group performance status of 3, and Charlson comorbidity index of 3 has predicted 5-yr CSM of 2.9-5.6% across treatments, but 5-yr OCM of 29% and risk of 90-d Clavien grade 3-5 complications of 1.9% for RN, 5.8% for PN, and 3.6% for TA. Limitations include selection bias, heterogeneity in practice across treatment sites and the study time period, and lack of control for surgeon/hospital volume.

CONCLUSIONS

We present a risk calculator incorporating pretreatment features to estimate treatment-specific competing risks of mortality and complications for use during shared decision-making and personalized treatment selection for RCMs.

PATIENT SUMMARY

We present a risk calculator that generates personalized estimates of the risks of death from cancer or other causes and of complications for surgical, ablation, and surveillance treatment options for patients with stage 1 kidney tumors.

Adrenalectomy outcomes predicted by a 5-item frailty index (5-iFI) in the ACS-NSQIP database

BACKGROUND

Frailty has been shown to be a predictor of adverse postoperative outcomes. This study aims to evaluate a 5-item frailty index (5-iFI) as a predictor of complications as well as healthcare resource utilization (HCRU) following adrenalectomy.

METHODS

All adrenalectomy cases recorded in the ACS-NSQIP database from 2015 to 2018 were analyzed. Primary outcomes of interest were Clavien-Dindo [CD] I/II or CD IV complications and HCRU. HCRU outcomes were prolonged length of stay (PLOS), discharge to continued care (DCC), and unplanned 30-day readmission (UR).

RESULTS

4358 patients were included. Higher 5-iFI scores were associated with higher rates of CDI/II, CDIV, and increased HCRU (p < 0.05). On multivariate analysis, 5-iFI scores were found to be independent predictors of adverse clinical and HCRU outcomes.

CONCLUSIONS

Frailty tools like the 5i-FI can be useful in preoperative risk-benefit analysis, patient counseling, and planning prehabilitation interventions.

Venous Thromboembolism in Surgical Lung Cancer Patients: A Provincial Population-Based Study

BACKGROUND

Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in surgical patients. Thoracic surgery patients are at increased risk due to inherent technical and disease-specific factors. Other surgical specialties have adopted post-discharge extended VTE prophylaxis; however, evidence is scarce in thoracic surgery. This study aims to identify VTE risk factors and associated mortality among surgical lung cancer patients.

METHODS

Using administrative databases, all patients in the province of Ontario undergoing lung cancer surgery from 2007 to 2017 were identified. Logistic regression identified VTE risk factors at 90-days and one-year postoperatively. A flexible parametric survival analysis compared mortality and survival up to 5 years after surgery between patients with and without VTE.

RESULTS

Of 65,513 patients diagnosed with lung cancer, 12,626 (19.3%) underwent surgery. VTE incidence at 90-days and 1-year postoperatively was 1.3% and 2.7%, respectively. Open and more extensive resections carried an increased VTE-risk, with pneumonectomy conferring the highest risk (OR = 2.36; p<0.001). Stage III and IV disease carried a 3.19 and 4.97-times higher risk of VTE, respectively, compared to stage I (p<0.001). The hazard ratio for mortality at one year for patients with a VTE was 2.01 (p<0.001). Patients suffering a VTE had reduced 5-year survival.

CONCLUSIONS

Patients undergoing pneumonectomy and those with advanced stage have an increased VTE-risk. Patients suffering a thrombotic complication have an increased risk of mortality, and decreased 5-year survival. Accordingly, strategies to reduce VTE risk should be considered in patients undergoing high risk operations to reduce the mortality of VTEs.

Frailty as a Predictor of Mortality for Fenestrated EVAR and Open Surgical Repair of Aortic Aneurysms Involving Visceral Vessels

OBJECTIVES

Frailty has been correlated with poor outcomes after major surgery across multiple specialties, but has not been studied in patients undergoing open or endovascular repair of suprarenal and thoracoabdominal aortic aneurysms. Fenestrated endovascular aneurysm repair (FEVAR) has emerged as a lower risk alternative to open surgical repair (OSR) for patients with complex aortic aneurysms involving the visceral artery branches. The objective of the current study was to examine the relationship between frailty and peri-operative outcomes for FEVAR and OSR in patients with suprarenal and thoracoabdominal aortic aneurysms.

METHODS

The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent FEVAR or OSR for the years 2011 through 2017. Frailty was quantified using a modified 5-factor frailty index (mFI-5) that was previously validated for surgical patients. Frailty was correlated with the primary endpoint of 30-day mortality. Logistic regression was used to identify predictors of 30-day mortality.

RESULTS

A total of 675 FEVAR and 1,779 OSR operations were included in the analysis. The 30-day mortality rate was 3.0% for FEVAR and 7.1% for OSR (P = 0.002). Increasing frailty was significantly associated with higher 30-day mortality for both FEVAR (P = 0.018) and OSR (P = 0.0003). Independent predictors of 30-day mortality were frailty score (Odds Ratio [OR] 1.22 [per 0.1-unit increase]; P = 0.0005), type of repair (OSR versus FEVAR, OR 2.46; P = 0.0001), age (OR 1.03; P = 0.0025), female sex (OR 1.61; P = 0.007), Hispanic ethnicity (OR 2.68; P = 0.021), American Society of Anesthesiology [ASA] class (OR 1.57; P = 0.035), preoperative dialysis (OR 3.45; P = 0.032), and history of bleeding disorder (OR 2.60; P < 0.0001).

CONCLUSIONS

Frailty, as measured using a mFI-5 score, is an independent predictor of 30-day mortality, overall complications, and length of stay after FEVAR or OSR. Frailty should be used to identify patients at high risk of adverse postoperative outcomes to determine if this risk is modifiable or whether nonoperative is the most appropriate option. FEVAR may offer improved 30-day outcomes, compared to OSR, for the frailest patients.

The clinical application of frailty in nephrology and transplantation

PURPOSE OF REVIEW

Clinicians treating end-stage kidney disease (ESKD) and kidney transplant patients face unique challenges in their care because of the high burden of frailty in these patients. Frailty has gained significant attention by medical and surgical specialties for risk stratification in the past decades. This review highlights the importance of measuring frailty in kidney transplant candidates and recipients.

RECENT FINDINGS

Emerging data support that frailty is present even at younger ages among patients undergoing dialysis, transplant evaluation, or transplantation. It is estimated that 18.8% of younger (18-64 years) candidates, 25.2% of older (≥65 years) candidates, 14.3% of younger recipients, and 20.8% of older recipients are frail. Additionally, frailty is dynamic and subject to change pretransplantation and posttransplantation. Although many patients and clinicians are aware of the importance of measuring frailty, further studies addressing the need for interventions to reduce frailty burden are needed.

SUMMARY

Frailty is independently associated with many adverse outcomes in ESKD and kidney transplant populations. Given the growing number of ESKD and kidney transplant patients, it is pivotal to expand the utility of frailty measurement in clinical practice, recognize the burden of frailty, and identify appropriate interventions to mitigate the adverse effects of frailty.

Radical cystectomy and perioperative chemotherapy in octogenarians with bladder cancer

INTRODUCTION

We aimed to compare the treatment patterns and oncological outcomes, including postoperative morbidity and chemotherapy use, between octogenarians and patients <80 years of age who underwent radical cystectomy for bladder cancer.

METHODS

We conducted a retrospective analysis of 119 patients who underwent radical cystectomy for bladder cancer at our center between January 2013 and April 2019. Comorbidities, clinical and pathological data, 30-day postoperative morbidity, and perioperative chemotherapy use were compared between octogenarians (n=31) and younger patients (n=88). Cancer-specific and overall survival rates were estimated with the Kaplan-Meier method and compared between the groups.

RESULTS

No significant differences were found between the age groups in the clinical and pathological findings, including Charlson comorbidity index, modified frailty index, albumin level, renal function, and TNM stage. The median followup for survivors was 19 months (interquartile range [IQR] 11-30). Major complications (Clavien-Dindo grade ≥3) and 30-day postoperative mortality rates did not differ between the age groups (p=0.3 and p=0.18, respectively). Despite no difference in baseline glomerular filtration rates, perioperative chemotherapy utilization rate was lower among octogenarians compared to younger patients (13% vs. 34%, p=0.03). Estimated two-year cancer-specific survival rates for octo-generians and younger patients were 40% and 75%, respectively. Similarly, estimated two-year overall survival rates were 30% and 69%, respectively. Both cancer-specific and overall survival rates were significantly lower in octogenarians (p=0.007 and p=0.001, respectively).

CONCLUSIONS

Radical cystectomy in octogenarians results in comparable short-term outcomes as in younger patients. However, in the elderly population, perioperative chemotherapy utilization rates are lower and survival is inferior.

Role of Race in Short-Term Outcomes for 1700 Consecutive Patients Undergoing Brain Tumor Resection

BACKGROUND

Access to medical care seems to be impacted by race. However, the effect of race on outcomes, once care has been established, is poorly understood.

PURPOSE

This study seeks to assess the influence of race on patient outcomes in a brain tumor surgery population.

IMPORTANCE AND RELEVANCE TO HEALTHCARE QUALITY

This study offers insights to if or how quality is impacted based on patient race, after care has been established. Knowledge of disparities may serve as a valuable first step toward risk factor mitigation.

METHODS

Patients differing in race, but matched on other outcomes affecting characteristics, were assessed for differences in outcomes subsequent to brain tumor resection. Coarsened exact matching was used to match 1700 supratentorial brain tumor procedures performed over a 6-year period at a single, multihospital academic medical center. Patient outcomes assessed included unplanned readmission, mortality, emergency department (ED) visits, and unanticipated return to surgery.

RESULTS

There was no significant difference in readmissions, mortality, ED visits, return to surgery after index admission, or return to surgery within 30 days between the two races.

CONCLUSION

This study suggests that race does not independently influence postsurgical outcomes but may instead serve as a proxy for other closely related demographics.

Role of pre-operative frailty status in relation to outcome after carotid endarterectomy: a systematic review

Carotid endarterectomy (CEA) is a surgical treatment option to prevent ischemic cerebrovascular accidents. Patients that present with pre-operative frailty might have an elevated risk for unfavorable outcomes after the CEA. A systematic search, using Medline, Embase, Web of Science and Cochrane Database, was performed for relevant literature on frailty in patients undergoing CEA. The study protocol was registered with PROSPERO (CRD42020190345). Eight articles were included. The pooled prevalence for pre-operative frailty was 23.9% (95% CI: 12.98-34.82). A difference in the incidence of complications between frail and non-frail patients (6.4% vs. 5.2%, respectively) and a difference in hospital length of stay [2 (IQR: 2-3) days vs. 1 (IQR: 1-2) day, respectively] were described. The 30-day mortality after CEA was 0.6% for non-frail patients, 2.6% for frail patients, and 4.9% for very frail patients (P<0.001). For 3-year mortality, a >1.5-fold increased risk was found for frail patients (OR 1.7, 95% CI: 1.4-2.0) and a >2.5-fold increased risk for very frail patients (OR 2.6, 95% CI: 2.2-3.1). In conclusion, this review shows the impact of frailty on outcome after CEA. Pre-operative frailty assessment with a validated, multi-domain tool should be implemented in the clinical setting as it will provide information on post-operative surgical outcomes and mortality risk but also frailty trajectory and cognitive decline.

Risk prediction score and appendicectomy in the elderly: A single centre 5-year retrospective cohort study

BACKGROUND

Appendicitis is a common surgical emergency that can be a challenging entity to manage. In the elderly, it is associated with significant morbidity and mortality. Risk prediction is not routinely performed prior to surgery.

METHODS

All patients aged >65 years undergoing appendicectomy over 5 years from one NHS Trust were included. Age, American Society of Anesthesiologists physical status classification system (ASA grade), Rockwood score, type of surgery, length of stay, morbidity and 90-day mortality were recorded. ACS NSQIP was retrospectively calculated. Spearman's Rank correlation coefficient and linear regression analysis were conducted, assessing correlation between ASA, Age, Rockwood Score and ACS NSQIP with length of stay and post-operative complications.

RESULTS

A total of 225 patient cases were reviewed. A complication rate of 29.3% was recorded, with a 6.7% serious complication rate. Two mortalities occurred. ASA, Age, Rockwood and NSQIP scoring systems all showed low degree positive correlation with length of stay (+0.16-+0.34). As predictors of length of stay, ASA was superior. Rockwood and age showed low degree positive correlation (+0.25-+0.33) with post-operative complications. NSQIP and ASA demonstrated a greater degree of correlation (+0.38-+0.40).

CONCLUSION

Both ASA and ACS NSQIP appear superior indicators for outcomes compared to age and Rockwood score. However, caution is warranted when interpreting the superiority of ASA over validated risk stratification tools. Therefore, we advocate the use of pre-operative risk stratification for elderly patients undergoing low-risk surgery such as appendicectomy. Validated tools are not routinely applied in many centres currently. Utilisation of scores such as ACS NSQIP may help improve consent, patient selection, outcomes and expectations.

Systematic Review of Treatments for Colorectal Metastases in Elderly Patients to Guide Surveillance Cessation Following Hepatic Resection for Colorectal Liver Metastases

BACKGROUND

Although included in surveillance programmes for colorectal cancer (CRC) metastases, elderly patients are susceptible to declines in health and quality of life that may render them unsuitable for further surveillance. Deciding when to cease surveillance is challenging.

METHODS

There are no publications focused on surveillance of elderly patients for CRC metastases. A systematic review of studies reporting treatment outcomes for CRC metastases in elderly patients was performed to assess the risk-benefit balance of the key objectives of surveillance; detecting and treating CRC metastases.

RESULTS

Sixty-eight eligible studies reported outcomes for surgery and chemotherapy in the elderly. Liver resections and use of chemotherapy, including biologics, are more conservative and have poorer outcomes in the elderly compared with younger patients. Selected studies demonstrated poorer quality-of-life (QoL) following surgery and chemotherapy. Studies of ablation in elderly patients are limited.

DISCUSSION

The survival benefit of treating CRC metastases with surgery or chemotherapy decreases with advancing age and QoL may decline in the elderly. The relatively lower efficacy and detrimental QoL impact of multimodal therapy options for detected CRC metastases in the elderly questions the benefit of surveillance in some elderly patients. Care of elderly patients should thus be customized based on their preference, formal geriatric assessment, natural life-expectancy, and the perceived risk-benefit balance of treating recurrent CRC metastases. Clinicians may consider surveillance cessation in patients aged 75 years and above if geriatric assessment is unsatisfactory, patients decline surveillance, or patient fitness deteriorates catastrophically.

The relation between physical fitness, frailty and all-cause mortality after elective endovascular abdominal aortic aneurysm repair

BACKGROUND

Accurate determination of probable surgical outcomes is fundamental in decision-making regarding appropriate abdominal aortic aneurysm treatment. These outcomes depend, among other factors, on patient-related factors such as physical fitness. The primary aim of this study was to evaluate the correlation between physical fitness, measured by the metabolic equivalent of task (MET) score and the five-factor Modified Frailty Index (MFI-5), and all-cause mortality.

METHODS

Four hundred twenty-nine patients undergoing elective endovascular treatment of an infrarenal aortic aneurysm (EVAR) from January 2011 to September 2018 were identified in an existing local abdominal aortic aneurysm database. Physical fitness was measured by the MFI-5 and the METs as registered during preoperative screening. The primary end point was 1-year all-cause mortality and secondary end points included 5-year all-cause mortality, freedom from aneurysm-related mortality and aneurysm-related reinterventions. Correlations were analyzed using Spearman's rho and survival was analyzed using Kaplan-Meier analyses. The effect of physical fitness on mortality was assessed by binary logistics regression analyses.

RESULTS

There was a positive correlation between the MFI-5 and 1-year all-cause mortality (Rho = 0.163; P = .001), but not between the METs and 1-year all-cause mortality (Rho = -0.083; P = .124). A significant correlation between both MFI-5 and METs and 5-year all-cause mortality was observed (Rho = 0.255; P < .001 and Rho = -0.154; P = .004). When stratified by the MFI-5, the 1- and 5-year follow-up survival rates were 95.1% and 85.9%, respectively, in the group with the lowest MFI-5 and 74.5% and 33.1% in the group with the highest MFI-5 score (P = .007 and P < .001). When stratified by METs categories for 1-year follow-up, no significant differences in survival between the groups were observed (P = .090). The 5-year follow-up survival rate was 39.4% in the lowest METs category and 76.3% in the highest METs category (P = .039). Logistic regression analysis, assessing the impact of age, sex, METs, and the MFI-5 on the risk of all-cause mortality, showed that only age and the MFI-5 made a significant contribution.

CONCLUSIONS

There is a significant positive association between the MFI-5 and both the 1- and 5-year all-cause mortality rates after EVAR; METs only correlated with the 5-year all-cause mortality. Only age and the MFI-5 contributed to predicting overall survival after EVAR; therefore, it could be recommended to add the MFI-5 for guidance in preoperative counselling.

Short-term outcomes in older patients with peritoneal malignancy treated with cytoreductive surgery and HIPEC: Experience with 245 patients from a national centre

BACKGROUND

Cytoreductive Surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly accepted as the optimal management of selected patients with peritoneal malignancy. There is limited published evidence on outcomes in older patients treated by this complex therapeutic strategy.

METHODS

A retrospective review of a prospective database of all patients who underwent CRS with HIPEC in a single institution over seven years. A comparative analysis of outcomes in patients under 65 undergoing CRS and HIPEC with patients ≥65 years was performed. The key endpoints were morbidity, mortality, reintervention rate and length of stay in the high dependency/intensive care (HDU/ICU) units.

RESULTS

Overall, 245 patients underwent CRS and HIPEC during the study period, with 76/245 (31%) ≥65 years at the time of intervention. Tumour burden measured by the peritoneal carcinomatosis index (PCI) score was a median of 11 for both groups. Median length of hospital stay in the ≥65-year-old group was 14.5 days versus 13 days in the <65-year-old group (∗p = 0.01). Patients aged ≥65-years spent a median of one more day in the critical care unit ∗(p = 0.001). Significant morbidity (Clavien-Dindo ≥ Grade IIIa) was higher in the ≥65-year than the <65-year group (18.4% versus 11.2%). There were no perioperative deaths in the ≥65-year group.

CONCLUSION

This study demonstrates higher perioperative major morbidity in ≥65-year group, but with low mortality in patients undergoing CRS/HIPEC for disseminated intraperitoneal malignancy. This increased morbidity does not translate into higher rates of re-interventions and highlights the importance of optimal patient selection.

Frailty as predictor of complications in patients undergoing percutaneous nephrolithotomy (PCNL)

INTRODUCTION & OBJECTIVE

Surgical complications are difficult to predict, despite existing tools. Frailty phenotype has shown promise estimating postoperative risk among the elderly. We evaluate the use of frailty as a predictive tool on patients undergoing percutaneous renal surgery.

METHODS

Frailty was prospectively analyzed using the Hopkins Frailty Index, consisting of 5 components yielding an additive score: patients categorized not frail, intermediate, or severely frail. Primary outcomes were complications during admission and 30-day complication rate. Secondary outcomes included overall hospital length of stay (LOS) and discharge location.

RESULTS

A total of 100 patients recruited, of whom five excluded as they did not need the procedure. A total of 95 patients analyzed; 69, 10, and 16 patients were not frail, intermediate, and severely frail, respectively. There were no differences in blood loss, number of dilations, presence of a staghorn calculus, laterality, or location of dilation. Severely frail patients were likely to be older and have a higher American Society of Anesthesiologists score and Charlson comorbidity index. Patients of intermediate or severe frailty were more likely to exhibit postoperative fevers, bacteremia, sepsis, and require ICU admissions (P < 0.05). Frail patients had a longer LOS (P < 0.001) and tended to require skilled assistance when discharge (p < 0.0001).

CONCLUSIONS

Frailty assessment appears useful stratifying those at risk of extended hospitalization, septic complications, and need for assistance following percutaneous renal surgery. Risks of sepsis, bacteremia, and post-operative hemorrhage may be higher in frail individuals. Preoperative assessment of frailty phenotype may give insight into treatment decisions and represent a modifiable marker allowing future trials exploring the concept of "prehabilitation".

Novel bypass risk predictive tool is superior to the 5-Factor Modified Frailty Index in predicting postoperative outcomes

OBJECTIVE

This study aimed to develop risk predictive models of 30-day mortality, morbidity, and major adverse limb events (MALE) after bypass surgery for aortoiliac occlusive disease (AIOD) and to compare their performances with a 5-Factor Frailty Index.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program 2012-2017 Procedure Targeted Aortoiliac (Open) Participant Use Data Files were queried to identify all patients who had elective bypass for AIOD: femorofemoral bypass, aortofemoral bypass, and axillofemoral bypass (AXB). Outcomes assessed included mortality, major morbidity, and MALE within 30 days postoperatively. Major morbidity was defined as pneumonia, unplanned intubation, ventilator support for >48 hours, progressive or acute renal failure, cerebrovascular accident, cardiac arrest, or myocardial infarction. Demographics, comorbidities, procedure type, and laboratory values were considered for inclusion in the risk predictive models. Logistic regression models for mortality, major morbidity and MALE were developed. The discriminative ability of these models (C-indices) were compared with that of the 5-Factor Modified Frailty Index (mFI-5): a general frailty tool determined from diabetes, functional status, history of chronic obstructive pulmonary disease, history of congestive heart failure, and hypertension. Calculators were derived using the most significant variables for each of the three risk predictive models.

RESULTS

A total of 2612 cases (mean age 65.0, 60% male) were identified, of which 1149 (44.0%) were femorofemoral bypass, 1138 (43.6%) were aortofemoral bypass, and 325 (12.4%) were axillofemoral bypass. Overall, the rates of mortality, major morbidity, and MALE were 2.0%, 8.5%, and 4.9%, respectively. Twenty preoperative risk factors were considered for incorporation in the risk tools. Apart from procedure type, age was the most statistically significant predictor of both mortality and morbidity. Preoperative anemia and critical limb ischemia were the most significant predictors of MALE. All three constructed models demonstrated significantly better discriminative ability (P < .001) on the outcomes of interest as compared with the mFI-5.

CONCLUSIONS

Our models outperformed the mFI-5 in predicting 30-day mortality, major morbidity, and adverse limb events in patients with AIOD undergoing elective bypass surgery. Calculators were created using the most statistically significant variables to help calculate individual patient's postoperative risks and allow for better informed consent and risk-adjusted comparison of provider outcomes.

Transition in Frailty State Among Elderly Patients After Vascular Surgery

BACKGROUND

Frailty in the vascular surgical ward is common and predicts poor surgical outcomes. The aim of this study was to analyze transitions in frailty state in elderly patients after vascular surgery and to evaluate influence of patient characteristics on this transition.

METHODS

Between 2014 and 2018, 310 patients, ≥65 years and scheduled for elective vascular surgery, were included in this cohort study. Transition in frailty state between preoperative and follow-up measurement was determined using the Groningen Frailty Indicator (GFI), a validated tool to measure frailty in vascular surgery patients. Frailty is defined as a GFI score ≥4. Patient characteristics leading to a transition in frailty state were analyzed using multivariable Cox regression analysis.

RESULTS

Mean age was 72.7 ± 5.2 years, and 74.5% were male. Mean follow-up time was 22.7 ± 9.5 months. At baseline measurement, 79 patients (25.5%) were considered frail. In total, 64 non-frail patients (20.6%) shifted to frail and 29 frail patients (9.4%) to non-frail. Frail patients with a high Charlson Comorbidity Index (HR = 0.329 (CI: 0.133-0.812), p = 0.016) and that underwent a major vascular intervention (HR = 0.365 (CI: 0.154-0.865), p = 0.022) had a significantly higher risk to remain frail after the intervention.

CONCLUSIONS

The results of this study, showing that after vascular surgery almost 21% of the non-frail patients become frail, may lead to a more effective shared decision-making process when considering treatment options, by providing more insight in the postoperative frailty course of patients.

Frailty of the Heart Recipient

Frailty has been defined as a state of increased vulnerability due to a decline in the reserve and function of multiple physiological systems. Initially conceived as a geriatric syndrome indicative of physiological aging, it is now apparent that frailty can also be observed as a manifestation of chronic disease states including heart failure. Estimates of the prevalence of frailty in heart failure vary according to the age of the study population and the frailty instrument used, however multiple studies have identified frailty to be prevalent in patients with advanced heart failure including those who are referred for heart transplantation. Frailty is emerging as an independent predictor of mortality both before and after bridge-to-transplant ventricular assist device (BTT VAD) implantation and heart transplantation. Frailty is also predictive of prolonged hospitalization following these procedures. Heart failure-associated frailty is a dynamic state. While reversibility of frailty can be anticipated in younger heart failure patients, predicting the reversibility of frailty is more challenging in older patients who often have multiple comorbidities that may contribute to the frailty syndrome. Prehabilitation is a promising approach to both preventing and reversing frailty however more research is urgently needed to establish its effectiveness in mitigating the adverse impacts of frailty on post-VAD and posttransplant morbidity and mortality.

The influence of race on outcomes following pituitary tumor resection

OBJECTIVE

To assess the influence of race on short-term patient outcomes in a pituitary tumor surgery population.

PATIENTS AND METHODS

Coarsened exact matching was used to retrospectively analyze consecutive patients (n = 567) undergoing pituitary tumor resection over a six-year period (June 07, 2013 to April 29, 2019) at a single, multi-hospital academic medical center. Black/African American and white patients were exact matched based on twenty-nine (29) patient, procedure, and hospital characteristics. Matching characteristics included surgical costs, American Society of Anesthesiologists grade, duration of surgery, and Charlson Comorbidity Index, amongst others. Outcomes studied included unplanned 90-day readmission, emergency room (ER) evaluation, and unplanned reoperation.

RESULTS

Ninety-two (n = 92) patients were exact matched and analyzed. There was no significant difference in 90-day readmission (p = 0.267, OR (black/AA vs white) = 0.500, 95% CI = 0.131-1.653) or ER evaluation within 90 days (p = 0.092, OR = 3.000, 95% CI = 0.848-13.737) between the two cohorts. Furthermore, there was no significant difference in the rate of unplanned reoperation throughout the duration of the follow up period between matched black/African American and white patients (p = 0.607, OR = 0.750, 95% CI = 0.243-2.211).

CONCLUSION

This study suggests that the effect of race on post-operative outcomes is largely mitigated when equal access is attained, and when race is effectively isolated from socioeconomic factors and comorbidities in a population undergoing pituitary tumor resection.

Precision Health Analytics With Predictive Analytics and Implementation Research: JACC State-of-the-Art Review

Emerging data science techniques of predictive analytics expand the quality and quantity of complex data relevant to human health and provide opportunities for understanding and control of conditions such as heart, lung, blood, and sleep disorders. To realize these opportunities, the information sources, the data science tools that use the information, and the application of resulting analytics to health and health care issues will require implementation research methods to define benefits, harms, reach, and sustainability; and to understand related resource utilization implications to inform policymakers. This JACC State-of-the-Art Review is based on a workshop convened by the National Heart, Lung, and Blood Institute to explore predictive analytics in the context of implementation science. It highlights precision medicine and precision public health as complementary and compelling applications of predictive analytics, and addresses future research and training endeavors that might further foster the application of predictive analytics in clinical medicine and public health.

Perioperative and Functional Outcomes of Robot-Assisted Radical Prostatectomy in Octogenarian Men

Background: The functional and oncologic outcomes of robot-assisted radical prostatectomy (RARP) in octogenarians are not well studied. We sought to study the perioperative, functional, and oncologic outcomes of RARP in octogenarian men. Methods: Between January 2009 and 2019, 46 patients ≥80 years with localized prostate cancer (PCa) underwent RARP in three high-volume robotic urologic practices in the United States. Clinical and pathologic features, and perioperative and postoperative complications were retrospectively evaluated. Functional outcomes for urinary and sexual function were collected via patient-reported questionnaires. Continence was defined as the use of zero or one safety pad per day. Results: The median (interquartile range) age was 81 (80-82), the mean (standard deviation [SD]) operative time was 116.5 (36.4) minutes, and the mean (SD) blood loss was 132 (35.6) mL. All cases were completed robotically, no intraoperative complications were encountered, and the mean length of stay was 1.21 (0.78) days. Regarding 30- and 90-day complication, nine patients had postoperative complications; seven were Clavien-Dindo grade I-II, and two were Clavien-Dindo grade ≥III. Post-RARP continence rates at 3 and 12 months were 68.4% and 84.8%, respectively. Conclusions: RARP represents a feasible option to treat PCa in well-selected octogenarian men. Careful patient selection and counseling are critical before offering surgical treatment for these men.

Robotic versus open pancreaticoduodenectomy: Is there any difference for frail patients?

BACKGROUND

Old age and frailty are predictors of early postoperative results after pancreatic surgery. We analysed the results of robotic and open pancreatoduodenectomy in elderly and frail patients.

METHODS

Data from the local robotic pancreatoduodenectomy database were reviewed and matched with those from open operations during the same period (2014-2020). Both old age and frailty were used to determine any correlation with postoperative outcomes. Elderly patients were defined as patients aged 70 years or more, while frailty was classified according to the validated modified Frailty Index.

RESULTS

A total of 118 pancreatoduodenectomies were included in the analysis: 65 (55.1%) robotic and 53 (44.9%) open. More than 50% of patients were frail. Overall, 7.6% of patients experienced grade IV Clavien-Dindo complications, and 3.4% died within 90 days after surgery. Frail patients experienced a similar rate of severe complications after robotic vs. open operations (5.3 vs. 11.6; p = 0.439) but earlier refeeding (3 days vs. 4 days; p = 0.006) and earlier drain removal (6 days vs. 7 days; p = 0.046) when operated on by a robotic approach. The oncological outcomes, including limphnodes retrieval, residual disease, recurrences, and survival, were not influenced by the surgical approach. Non-elderly patients also showed more benefits with the robotic approach (lower complication index, earlier refeeding, and drain removal).

CONCLUSIONS

Robotic pancreatoduodenectomy is associated with risks of major complications that are comparable to those of open operation in frail patients. Some perioperative parameters (refeeding, drain removal) seem to favour robotics in frail patients and younger patients, although at the price of longer operating times.

Predictive Effect of Frailty on Amputation, Mortality, and Ambulation in Patients Undergoing Revascularization for Acute Limb Ischemia

BACKGROUND

Frailty is a common, age-associated syndrome that has been used to predict postoperative outcomes in vascular surgery. This study examines if standard measures of frailty correlate with postoperative outcomes for patients undergoing revascularization for acute limb ischemia (ALI).

METHODS

A retrospective study was conducted on all adult patients undergoing revascularization for ALI at an academic medical center between January 2016 and June 2019. Frailty was calculated with the 11-factor modified frailty index (mFI-11), derived from the Canadian Study of Health and Aging Frailty Index. Outcomes examined included in-hospital mortality, major amputation, site of discharge, and ambulatory status at follow-up.

RESULTS

Fifty-three ambulatory patients presented with ALI during the study time period, with 13.2% deemed not frail (mFI-11 < 3) and 86.8% deemed frail (mFI-11 ≥ 3). Frailty was significantly correlated with discharge to a skilled nursing facility (P = 0.028) and nonambulation at follow-up (P = 0.002). There was no significant correlation with other outcomes, including mortality and amputation. On multivariate analysis, frailty was the only factor contributing to nonambulation at follow-up (P = 0.012). Endovascular treatment did not mitigate the effects of frailty on discharge site and ambulatory status.

CONCLUSIONS

Frailty is exceedingly common in patients with ALI. Although frailty predicts discharge site and nonambulation at follow-up, it is not associated with amputation or death. Therefore, frail patients should not be denied open or endovascular revascularization for ALI.

Role of predictive markers for severe postoperative complications in gynecological cancer surgery: a prospective study (RISC-Gyn Trial)

BACKGROUND

Surgery for gynecological cancer involves highly invasive and complex procedures potentially associated with various complications, which can cause extended hospital stays and delay of subsequent therapy, with a detrimental effect on the prognosis. The aim of this study was to explore and define the predictors of severe postoperative complications in patients undergoing surgery for gynecologic cancer.

METHODS

Patients undergoing surgery for gynecologic cancers were analyzed prospectively from October 2015 through January 2017. Using validated assessment tools preoperatively, we assessed comorbidities, performance status, quality of life, nutritional and body composition by bioelectrical impedance analysis, and the surgical data of each patient. Surgical complications were graded using the Clavien-Dindo criteria. Using stepwise logistic regression models, we identified predictive markers for postoperative complications.

RESULTS

Of the 226 enrolled patients, 40 (17.7%) experienced a grade ≥IIIb complication according to the Clavien-Dindo criteria. In the regression analysis, overweight/obesity (body mass index >25) (OR 6.41, 95% CI 2.38 to 17.24; p<0.001) and impaired physical functioning defined by a quality of life questionnaire (OR 4.19, 95% CI 1.84 to 9.50; p=0.001) emerged as significant predictors of postoperative complications. Moreover, postoperative complications were predicted by phase angle of bioelectrical impedance analysis <4.75° (OR 3.11, 95% CI 1.35 to 7.16; p=0.008) and Eastern Cooperative Oncology Group (ECOG) performance status >1 (OR 2.51, 95% CI 1.06 to 5.92; p=0.04). Intraoperative factors associated with higher risk of postoperative complications were increased use of norepinephrine (>11 µg/kg/min) (OR 5.59, 95% CI 2.16 to 14.44; p<0.001) and performance of large bowel resection (OR 4.28, 95% CI 1.67 to 10.97; p=0.002).

CONCLUSION

In patients undergoing surgery for gynecological cancer, preoperative evaluation of performance status according to ECOG, domains of quality of life and nutritional status, as well as intraoperative monitoring of risk factors, might help to identify patients at high risk for severe postoperative complications, and thus reduce surgical morbidity and mortality.

Frailty Is Associated with In-Hospital Morbidity and Nonroutine Disposition in Brain Tumor Patients Undergoing Craniotomy

OBJECTIVE

Frailty is associated with postoperative morbidity in multiple surgical disciplines. We evaluated the association between frailty and early postoperative outcomes for brain tumor patients using a national database.

METHODS

We reviewed the Nationwide Readmissions Database from 2010 to 2014. International Classification of Diseases, ninth revision, codes were used to identify benign and malignant brain tumors treated with surgical resection. Pituitary tumors were excluded. Frailty was assessed using the Johns Hopkins Adjusted Clinical Groups frailty indicator tool. Multivariable exact logistic regression was used to conduct analyses assessing the association between frailty and the outcome variables. Statistical significance was defined as P < 0.001.

RESULTS

The criteria for frailty were met for 7209 of 87,835 patients (8.2%). After adjustment for patient and hospital factors, frailty was independently associated with in-hospital surgical complications (odds ratio [OR], 1.48; 95% confidence interval [CI] 1.37-1.59; P < 0.0001), mental status changes (OR, 1.9; 95% CI, 1.72-2.09; P < 0.0001), and pulmonary insufficiency (OR, 1.75; 95% CI, 1.55-1.96; P < 0.0001). Frailty was associated with an increased length of stay (incident rate ratio, 1.92; 95% CI, 1.87-1.98; P < 0.0001) and nonroutine disposition (OR, 1.84; 95% CI, 1.72-1.97; P < 0.0001). In-hospital mortality was greater for frail patients (2.2% vs. 1.4%; P < 0.0001), but the difference did not achieve significance on multivariate analysis. Frail patients were not more likely to be readmitted.

CONCLUSION

Frailty is associated with in-hospital complications and nonroutine disposition after craniotomy for benign and malignant brain tumors. Additional work is needed to identify prehabilitation or in-hospital strategies to improve the care and outcomes of these at-risk patients.

Can Fried Frailty Score predict postoperative morbidity and mortality in gynecologic cancer surgery? Results of a prospective study

BACKGROUND

Aim of this study is to evaluate the predictive ability of Fried Frailty Score for surgical outcomes in patients undergoing gynecologic cancer surgery.

METHODS

This is a prospective cohort study at an academic gynecological cancer center from Oct 2015 through Jan 2017. We applied systematically numerous screening tools, geriatric questionnaires and single measurements which may provide predictions for surgical outcomes. We classified frailty according to the Fried definition and surgical complications were graded according Clavien-Dindo criteria. Using logistic regression analysis, we identified predictive clinical variables for postoperative complications (POC).

RESULTS

Overall 226 patients were enrolled (median age 59 years, range 18-87 years). The prevalence of frailty based on the presence of three or more frailty criteria was 14.2%, the presence of one or two frailty criteria was classified as prefrail with 59.4% and without any presence as robust with 26.5%. Within 30 days of surgery, nine (3.8%) patients have died and 40 (18.3%) experienced a grade ≥ IIIb complication. In the regression analysis obesity (OR: 5.37, 95% CI 1.99-14.49, p = 0.001) as well as ECOG >1 (OR: 4.32, 95% CI 1.28-1.55, p = 0.018) and Albumin<3.6 g/dl (OR: 3.88, 95% CI 1.37-10.98, p = 0.011) emerged as significant predictors of postoperative complications (POC). Fried Frailty Score (OR: 2.41, 95% CI 0.91-6.41, p = 0.077) showed no significant additional predictive value.

CONCLUSION

Fried Frailty Score could help the surgeon to estimate the risk for POC among patients undergoing gynecologic cancer surgery. But preoperatively determined ECOG, BMI and Albumin can predict severe POC in patients undergoing gynecologic surgery more precisely and should be assessed routinely.

Impact of frailty on surgery for glioblastoma: a critical evaluation of patient outcomes and caregivers' perceptions in a developing country

OBJECTIVE

The authors aimed to evaluate the impact of age and frailty on the surgical outcomes of patients with glioblastoma (GBM) and to assess caregivers' perceptions regarding postdischarge care and challenges faced in the developing country of India.

METHODS

This was a retrospective study of patients with histopathologically proven GBM from 2009 to 2018. Data regarding the clinical and radiological characteristics as well as surgical outcomes were collected from the institute's electronic database. Taking Indian demographics into account, the authors used the cutoff age of 60 years to define patients as elderly. Frailty was estimated using the 11-point modified frailty index (mFI-11). Patients were divided into three groups: robust, with an mFI score of 0; moderately frail, with an mFI score of 1 or 2; and severely frail, with an mFI score ≥ 3. A questionnaire-based survey was done to assess caregivers' perceptions about postdischarge care.

RESULTS

Of the 276 patients, there were 93 (33.7%) elderly patients and 183 (66.3%) young or middle-aged patients. The proportion of severely frail patients was significantly more in the elderly group (38.7%) than in the young or middle-aged group (28.4%) (p < 0.001). The authors performed univariate and multivariate analysis of associations of different short-term outcomes with age, sex, frailty, and Charlson Comorbidity Index. On the multivariate analysis, only frailty was found to be a significant predictor for in-hospital mortality, postoperative complications, and length of hospital and ICU stay (p < 0.001). On Cox regression analysis, the severely frail group was found to have a significantly lower overall survival rate compared with the moderately frail (p = 0.001) and robust groups (p < 0.001). With the increase in frailty, there was a concomitant increase in the requirement for readmissions (p = 0.003), postdischarge specialist care (p = 0.001), and help from extrafamilial sources (p < 0.001). Greater dissatisfaction with psychosocial and financial support among the caregivers of severely frail patients was seen as they found themselves ill-equipped to provide postdischarge care at home (p < 0.001).

CONCLUSIONS

Frailty is a better predictor of poorer surgical outcomes than chronological age in terms of duration of hospital and ICU stay, postoperative complications, and in-hospital mortality. It also adds to the psychosocial and financial burdens of the caregivers, making postdischarge care challenging.

Influence of Frailty on Outcome in Older Patients Undergoing Non-Cardiac Surgery - A Systematic Review and Meta-Analysis

Frailty is increasingly recognized as a better predictor of adverse postoperative events than chronological age. The objective of this review was to systematically evaluate the effect of frailty on postoperative morbidity and mortality. Studies were included if patients underwent non-cardiac surgery and if frailty was measured by a validated instrument using physical, cognitive and functional domains. A systematic search was performed using EMBASE, MEDLINE, Web of Science, CENTRAL and PubMed from 1990 - 2017. Methodological quality was assessed using an assessment tool for prognosis studies. Outcomes were 30-day mortality and complications, one-year mortality, postoperative delirium and discharge location. Meta-analyses using random effect models were performed and presented as pooled risk ratios with confidence intervals and prediction intervals. We included 56 studies involving 1.106.653 patients. Eleven frailty assessment tools were used. Frailty increases risk of 30-day mortality (31 studies, 673.387 patients, risk ratio 3.71 [95% CI 2.89-4.77] (PI 1.38-9.97; I2=95%) and 30-day complications (37 studies, 627.991 patients, RR 2.39 [95% CI 2.02-2.83). Risk of 1-year mortality was threefold higher (six studies, 341.769 patients, RR 3.40 [95% CI 2.42-4.77]). Four studies (N=438) reported on postoperative delirium. Meta-analysis showed a significant increased risk (RR 2.13 [95% CI 1.23-3.67). Finally, frail patients had a higher risk of institutionalization (10 studies, RR 2.30 [95% CI 1.81- 2.92]). Frailty is strongly associated with risk of postoperative complications, delirium, institutionalization and mortality. Preoperative assessment of frailty can be used as a tool for patients and doctors to decide who benefits from surgery and who doesn't.

Comparison of Major Complications at 30 and 90 Days Following Radical Cystectomy

OBJECTIVES

To better understand the time-course in which major complications occur after radical cystectomy and to describe associations with complications at 30 and 90 days.

METHODS

A database of radical cystectomy cases was queried for preoperative, perioperative, and postoperative data. Follow-up extended to 90 days postsurgery and included major complications (Clavien III-V). Early (30-day) and late (90-day) complication rates were compared via McNemar's test, and patient characteristics were compared across complication time groups by one-way ANOVA or Fisher's exact tests. Multinomial logistic regression was used to explore associations between patient characteristics and complication timing.

RESULTS

Of 969 patients undergoing radical cystectomy, 210/969 (21.7%) experienced a complication within 90 days. The rate of major complication significantly differed at 30 and 90 days (14.4% [conflict of interest (CI): 12.4%-16.9%] vs 21.7% [CI: 19.2%-24.4%] respectively, P ≤.0001). Chronic obstructive pulmonary disease (COPD) (P = .03), Charlson Comorbidity Index (P = .02), and Indiana pouch diversion (P = .002) were significant predictors of early complication. Diabetes was the strongest predictor for late complication (OR: 2.42; P = 0.01). Diabetes was also a significant predictor for late genitourinary complications (OR 3.39; P = .01), and smoking history was a significant predictor for late infectious complications (OR 3.61; P = .01).

CONCLUSION

We identified a significant number of complications occurring after 30 days postcystectomy, including the majority of deaths and genitourinary complications. These findings suggest that assessment of complications exclusively at 30 days would fail to capture a large proportion of major complications and deaths. Understanding the time-course of complications postcystectomy will serve to better inform design of future outcome studies.

Exposure to surgery is associated with better long-term outcomes in patients admitted to Swedish intensive care units

BACKGROUND

Long-term outcomes of patients admitted to intensive care units (ICUs) after surgery are unknown. We investigated the long-term effects of surgical exposure prior to ICU admission.

METHODS

Registry-based cohort study. The adjusted effect of surgical exposure for mortality was examined using Cox regression. Secondary analysis with conditional logistic regression in a case-control subpopulation matched for age, gender, and Simplified Acute Physiology Score III (SAPS3) was also conducted.

RESULTS

72 242 adult patients (56.9% males, median age 66 years [IQR 50-76]), admitted to Swedish ICUs in 3-year (2012-2014) were followed for a median of 2026 days (IQR 1745-2293). Cardiovascular diseases (17.5%), respiratory diseases (15.8%), trauma (11.2%), and infections (11.4%) were the leading causes for ICU admission. Mortality at longest follow-up was 49.4%. Age; SAPS3; admissions due to malignancies, respiratory, cardiovascular and renal diseases; and transfer to another ICU were associated with increased mortality. Surgical exposure prior to ICU admission (adjusted hazard ratio [aHR] 0.90; 95% CI 0.87-0.94; P < .001), admissions from the operation theatre (aHR 0.94; CI 0.90-0.99; P = .022) or post-anaesthesia care unit (aHR 0.92; CI 0.87-0.97; P = .003) were associated with decreased mortality. Conditional logistic regression confirmed the association between surgical exposure and decreased mortality (adjusted odds ratio 0.82; CI 0.75-0.91; P < .001).

CONCLUSIONS

Long-term ICU mortality was associated with known risk factors such as age and SAPS3. Transfer to other ICUs also appeared to be a risk factor and requires further investigation. Prior surgical exposure was associated with better outcomes, a noteworthy observation given limited ICU admissions after surgery in Sweden.

Frailty, geriatric assessment and prehabilitation in elderly patients undergoing urological surgery - is there a need for change of the daily clinical practice? Synthesis of the available literature

Introduction

The population of older people is heterogeneous and constantly growing. Over 50% of urological operations are performed in elderly patients. Some elderly patients present with frailty syndrome - a state of increased vulnerability to external stressors resulting in increased risk of hospitalizations, adverse treatment outcomes and death. Currently, there is no widely accepted system of qualification and preparation for surgical treatment developed specifically for elderly patients.

Material and methods

We searched Medline/Pubmed, Embase and Cochrane Libraries databases from 2000-2020 (week 5). The following medical subject headings (MeSH) terms were used to ensure the sensitivity of the searches: geriatric assessment, frailty, urology, and prehabilitation. Relevant articles were also identified through a manual search of the reference lists of potentially relevant articles.

Results

A total of 23 papers met the criteria and were included in the current study. Screening for frailty seems to be promising in predicting adverse outcomes, but frail patients should undergo detailed geriatric assessment (GA) which may indicate a need for preoperative intervention which can be unavailable during the hospitalization. The concept of prehabilitation is becoming increasingly discussed in thoracic and abdominal surgery, but only a few studies are available in the field of urology.

Conclusions

Geriatric assessment seems to be a valuable tool for urologists in daily clinical practice. A proper form of prehabilitation may provide enhanced recovery after surgery.

Frailty is a useful predictive marker of postoperative complications after pancreaticoduodenectomy

Background

Frailty results in a high risk for disability, hospitalization, and mortality. This study aimed to investigate perioperative details of frail patients who underwent pancreatectomy and whether frailty can be a predictive factor of postoperative complications, especially of clinically relevant postoperative pancreatic fistula (CR-POPF).

Methods

This retrospective study included patients who underwent pancreatectomy in our hospital between August 2016 and March 2019. The patients were divided into frail and pre-/non-frail groups. The diagnostic criteria were based on the Japanese version of the Cardiovascular Health Study.

Results

Of 93 patients, 11 (11.8%) and 82 (88.2%) were frail and pre-/non-frail patients, with median ages of 82 and 72 years, respectively (p = 0.041). Postoperative complications (Clavien-Dindo ≧ IIIa) were found in 8 and 32 patients (p = 0.034), CR-POPF in 3 and 13 patients (p = 0.346), and postoperative hospital stays were 21 and 17 days (p = 0.041), respectively. On multivariate analysis, frailty was an independent predictive factor (odds ratio [OR] 5.604, 95.0% confidence interval [CI] 1.002-30.734; p = 0.047) of postoperative complications (Clavien-Dindo ≧ IIIa) after pancreaticoduodenectomy. On multivariate analysis, a soft pancreas (OR 5.696, 95.0% CI 1.142-28.149; p = 0.034) was an independent and significant predictive factor of CR-POPF after pancreaticoduodenectomy.

Conclusions

Frailty may be a useful predictive factor of postoperative complications in patients undergoing pancreaticoduodenectomy.

Assessing the Role of Patient Race in Disparity of 90-Day Brain Tumor Resection Outcomes

BACKGROUND

This study assesses the influence of race on patient outcomes in a brain tumor surgery population.

METHODS

Coarsened exact matching was used to retrospectively analyze 1700 supratentorial brain tumor procedures over a 6-year period (June 7, 2013 to April 29, 2019) at a single, multihospital academic medical center. Outcome measures included readmission, mortality, emergency room visits, and reoperation.

RESULTS

McNemar test (mid-P) showed no significant difference in 90-day mortality between the 2 races (P = 0.3018). However, there was a significant difference in 90-day readmissions between the 2 races (P = 0.0237). There was no significant difference in 90-day emergency room visits (P = 0.0579), 90-day return to surgery after index admission (P = 0.6015), or return to surgery within 90 days (P = 0.6776) between the 2 races. There was also no significant difference in return to surgery for the duration of the follow-up period (P = 0.8728).

CONCLUSIONS

This study suggests that race alone does not result in disparate outcomes; however, there was an associated difference in 90-day postsurgical readmissions. Despite coarsened exact matching, persistent differences in median household income may play a role in the disparate outcome noted.
