RESUMO

BACKGROUND: Frailty is an objective measurement capable of preoperatively identifying patients with increased risk of 30-d morbidity and mortality, though less is known about its utility beyond that timeframe. We hypothesized that preoperative frailty is associated with an increased risk of 1-y mortality in patients undergoing major intra-abdominal surgery. MATERIALS AND METHODS: Demographics, laboratory values, and traditional surgical risk assessments (American Society of Anesthesiologists scale, Eastern Cooperative Oncology Group Performance Status, Charlson Comorbidity Index) were collected prospectively. Preoperative frailty was evaluated using Fried criteria. Postoperative complications were defined by Clavien-Dindo Classification. One-year mortality data were gathered from phone calls, medical records, and the National Death Index. RESULTS: This study included 189 patients with a mean age of 62 years. Of the total, 59.8% were male and 71.4% were Caucasian. At enrollment, 139 (73.5%) patients were considered "not frail", whereas 50 (26.5%) were considered "intermediately frail" or "frail". A total of 73 (38.6%) patients experienced a 30-d postoperative complication. At 1 y, 15 (7.9%) patients had died, 5 (3.6%) not frail and 10 (20.0%) intermediately frail/frail patients. Postoperative mortality occurred <30 d, between 31-100 d, and >100 d in 3, 4, and 8 patients, respectively. Malignant neoplasm was documented as the underlying cause of death in 12 patients. All 30-d mortalities occurred in frail patients who had a postoperative complication. CONCLUSIONS: Frailty status is predictive of 1-y postoperative mortality. The Fried Frailty Criteria has the potential to more accurately evaluate surgical patients' mortality risk beyond the immediate postoperative period, particularly when considered collectively with traditional surgical risk assessment tools.

RESUMO

BACKGROUND: Frailty has gained recognition as an objective measure of a patient's physiologic reserve that ideally can replace the subjective biases of surgeons. In this study, we sought to examine the concordance between patient and attending surgeon perceptions of the patient's "fitness" before surgery. We then correlated these ratings with the patient's objective frailty scores. METHODS: Patients were prospectively enrolled from urology, general surgery, and surgical oncology clinics. Patients were asked to rate their ability to withstand the physical stress of the scheduled surgery on a visual analog scale. The operating surgeon then independently rated his assessment of the patient's ability to withstand surgery blinded to the patient's self assessment. RESULTS: A total of 203 patients were included. Median patient age and body mass index were 62 (range = 21-87) years and 28.1 kg/m(2) (18.0-53.1), respectively. The majority of patients were white (67%) and male (60.6%). A patients' self-assessment showed no correlation with their age; however, surgeons' ratings showed a positive correlation with patients' age. Patients' self-rated scores showed a positive correlation with their frailty score, although surgeons' ratings showed a stronger correlation. However, when stratified by age group, the positive correlation and predictive ability were lost (P value = 0.198). CONCLUSIONS: Although age is an established risk factor, our data demonstrate surgeons may place an overreliance on a patient's age in place of an objective measure of physiologic reserve. Conversely, patients tended to overestimate their ability to withstand the stress of surgery, possibly leading to unrealistic expectations of their recovery and outcomes.

RESUMO

PURPOSE: The incidence of lower urinary tract symptoms (LUTS) as the sole presenting symptom for bladder cancer has traditionally been reported to be low. The objective of this study was to evaluate the prevalence and clinical characteristics of newly diagnosed bladder cancer patients who presented with LUTS in the absence of gross or microscopic hematuria. MATERIALS AND METHODS: We queried our database of bladder cancer patients at the Atlanta Veteran's Affairs Medical Center (AVAMC) to identify patients who presented solely with LUTS and were subsequently diagnosed with bladder cancer. Demographic, clinical, and pathologic variables were examined. RESULTS: 4.1% (14/340) of bladder cancer patients in our series presented solely with LUTS. Mean age and Charlson Co-morbidity Index of these patients was 66.4 years (range = 52-83) and 3 (range = 0-7), respectively. Of the 14 patients in our cohort presenting with LUTS, 9 (64.3%), 4 (28.6%), and 1 (7.1%) patients presented with clinical stage Ta, carcinoma in Situ (CIS), and T2 disease. At a median follow-up of 3.79 years, recurrence occurred in 7 (50.0%) patients with progression occurring in 1 (7.1%) patient. 11 (78.6%) patients were alive and currently disease free, and 3 (21.4%) patients had died, with only one (7.1%) death attributable to bladder cancer. CONCLUSIONS: Our database shows a 4.1% incidence of LUTS as the sole presenting symptom in patients with newly diagnosed bladder cancer. This study suggests that urologists should have a low threshold for evaluating patients with unexplained LUTS for underlying bladder cancer.

RESUMO

INTRODUCTION: High-grade T1 (HGT1) bladder cancer represents a clinical challenge in that the urologist must balance the risk of disease progression against the morbidity and potential mortality of early radical cystectomy and urinary diversion. Using two non-muscle invasive bladder cancer (NMIBC) databases, we re-examined the rate of progression of HG T1 bladder cancer in our bladder cancer populations. MATERIALS AND METHODS: We queried the NMIBC databases that have been established independently at the Atlanta Veterans Affairs Medical Center (AVAMC) and the University of Pennsylvania to identify patients initially diagnosed with HGT1 bladder cancer. Demographic, clinical, and pathologic variables were examined as well as rates of recurrence and progression. RESULTS: A total of 222 patients were identified; 198 (89.1%) and 199 (89.6%) of whom were male and non-African American, respectively. Mean patient age was 66.5 years. 191 (86.0%) of the patients presented with isolated HG T1 disease while 31 (14.0%) patients presented with HGT1 disease and CIS. Induction BCG was utilized in 175 (78.8%) patients. Recurrence occurred in 112 (50.5%) patients with progression occurring in only 19 (8.6%) patients. At a mean follow-up of 51 months, overall survival was 76.6%. Fifty two patients died, of whom only 13 (25%) patient deaths were bladder cancer related. CONCLUSIONS: In our large cohort of patients, we found that the risk of progression at approximately four years was only 8.6%. While limited by its retrospective nature, this study could potentially serve as a starting point in re-examining the treatment algorithm for patients with HG T1 bladder cancer.

RESUMO

BACKGROUND: The definition of frailty, as modeled by the Fried criteria, has been limited primarily to the physical domain. The purpose of this study was to assess the additive value of cognitive function with existing frailty criteria to predict poor postoperative outcomes in a large multidisciplinary cohort of patients undergoing major operations. STUDY DESIGN: A 4-level composite frailty scoring system was created via the combination of the Fried frailty score and the Emory Clock Draw Test to assess preoperative frailty and cognitive impairment, respectively. Overall survival was defined as months from date of operation to date of death or last follow-up. RESULTS: This study included 330 patients undergoing major operations; mean age was 58 years and a total of 53 patient deaths occurred during 4-year follow-up. Among the robust cohort, 20 of 168 patients died (11.9%), and among those who were both physically frail and cognitively impaired, 11 of 26 patients died (42.3%). Multivariable analysis demonstrated the physically frail and cognitively impaired cohort to have a 3.92 higher risk of death (95% CI 1.66 to 9.26) compared with the cohort of robust patients (p = 0.002). Kaplan-Meier survival curves reveal an overall difference in long-term survival (log-rank p < 0.0001), driven mainly by the high risk of mortality among patients with both physical frailty and cognitive impairment. CONCLUSIONS: The use of a combined frailty and cognitive assessment score has a more powerful potential to predict adult patients at higher risk of overall survival than either measurement alone. The addition of cognitive assessment to physical frailty measure can lead to improved preoperative decision making and possibly early intervention, as well as more accurate patient counseling.

RESUMO

BACKGROUND: Frailty is an objective method of quantifying a patient's fitness for surgery. Its clinical use is limited by the time needed to complete, as well as a lack of evidence-based interventions to improve outcomes in identified frail patients. The purpose of this study was to critically analyze the components of the Fried Frailty Criteria, among other preoperative variables, to create a simplified risk assessment amenable to a busy clinical setting, while maintaining prognostic ability for surgical outcomes. STUDY DESIGN: We performed a prospective evaluation of patients that included the 5-component Fried Frailty Criteria, traditional surgical risk assessments, biochemical laboratory values, and clinical and demographic data. Thirty-day postoperative outcomes were the outcomes of interest. RESULTS: There were 351 consecutive patients undergoing major intra-abdominal operations enrolled. Analysis demonstrated that shrinking and grip strength alone hold the same prognostic information as the full 5-component Fried Frailty Criteria for 30-day morbidity and mortality. The addition of American Society of Anesthesia (ASA) score and serum hemoglobin creates a composite risk score, which facilitates easy classification of patients into discrete low (ref), intermediate (odds ratio [OR] 1.974, 95% CI 1.006 to 3.877, p = 0.048), and high (OR 4.889, 95% CI 2.220 to 10.769, p < 0.001) risk categories, with a corresponding stepwise increase in risk for 30-day postoperative complications. Internal validation by bootstrapping confirmed the results. CONCLUSIONS: This study demonstrated that 2 components of the Fried Frailty Criteria, shrinking and grip strength, hold the same predictive value as the full frailty assessment. When combined with American Society of Anesthesiologists score and serum hemoglobin, they form a straightforward, simple risk classification system with robust prognostic information.

RESUMO

BACKGROUND AND PURPOSE: Current surgical decision-making is overly subjective and often misjudges a patient's physiologic state. The concept of frailty has gained recent recognition and potentially represents a measureable phenotype, which can quantify a patient's physiologic reserve and risk of an adverse surgical outcome. We sought to investigate the relationship between preoperative markers of frailty and postoperative complications in patients undergoing minimally invasive surgery (MIS). METHODS: Frailty, using the methodology described by Fried and coworkers, was prospectively measured in patients who presented to urology, general surgery, and surgical oncology clinics where major MIS (endoscopic, laparoscopic, or robotic) was planned. The relationship between preoperative markers of frailty and 30-day postoperative complications was our primary outcome measure. RESULTS: Our cohort includes 80 patients. Mean age and body mass index were 60.0 (range 19-87) years and 29.2 (range 18.4-53.1) kg/m(2), respectively. The majority of patients were male (57.5%) and Caucasian (65.0%). Thirteen patients were deemed "intermediately frail" or "frail," and the remaining 67 were classified as "not frail." Thirteen (16.25%) patients experienced any postoperative complication. Five (38.5%) of the intermediately frail and frail patients experienced a complication, compared with eight (11.9%) of the not frail patients (odds ratio=5.914; 95% confidence interval=1.25-27.96; P=0.025). CONCLUSION: The advent of MIS has potentially lured surgeons into thinking older and patients with comorbidities may more easily tolerate this surgical approach compared with traditional open techniques. Our data suggest, however, that intermediately frail or frail patients are at increased risk of experiencing postoperative complications compared with not frail patients.

RESUMO

BACKGROUND: The decision as to whether a patient can tolerate surgery is often subjective and can misjudge a patient's true physiologic state. The concept of frailty is an important assessment tool in the geriatric medical population, but has only recently gained attention in surgical patients. Frailty potentially represents a measureable phenotype, which, if quantified with a standardized protocol, could reliably estimate the risk of adverse surgical outcomes. STUDY DESIGN: Frailty was prospectively evaluated in the clinic setting in patients consenting for major general, oncologic, and urologic procedures. Evaluation included an established assessment tool (Hopkins Frailty Score), self-administered questionnaires, clinical assessment of performance status, and biochemical measures. Primary outcome was 30-day postoperative complications. RESULTS: There were 189 patients evaluated: 117 from urology, 52 from surgical oncology, and 20 from general surgery clinics. Mean age was 62 years, 59.8% were male, and 71.4% were Caucasian. Patients who scored intermediately frail or frail on the Hopkins Frailty Score were more likely to experience postoperative complications (odds ratio [OR] 2.07, 95% CI 1.05 to 4.08, p = 0.036). Of all other preoperative assessment tools, only higher hemoglobin (p = 0.033) had a significant association and was protective for 30-day complications. CONCLUSIONS: The aggregate score of patients as "intermediately frail or frail" on the Hopkins Frailty Score was predictive of a patient experiencing a postoperative complication. This preoperative assessment tool may prove beneficial when weighing the risks and benefits of surgery, allowing objective data to guide surgical decision-making and patient counseling.
