Prediction Models for Forecasting Risk of Development of Surgical Site Infection after Lower Limb Revascularization Surgery: A Systematic Review. Ann Vasc Surg 2024; 102:140-151. [PMID: 38307235 DOI: 10.1016/j.avsg.2023.11.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 11/01/2023] [Accepted: 11/08/2023] [Indexed: 02/04/2024]
Abstract
BACKGROUND Surgical site infections (SSIs) are a common and potentially preventable complication of lower limb revascularization surgery associated with increased healthcare resource utilization and patient morbidity. We conducted a systematic review to evaluate multivariable prediction models designed to forecast risk of SSI development after these procedures. METHODS After protocol registration (CRD42022331292), we searched MEDLINE, EMBASE, CENTRAL, and Evidence-Based Medicine Reviews (inception to April 4th, 2023) for studies describing multivariable prediction models designed to forecast risk of SSI in adults after lower limb revascularization surgery. Two investigators independently screened abstracts and full-text articles, extracted data, and assessed risk of bias. A narrative synthesis was performed to summarize predictors included in the models and their calibration and discrimination, validation status, and clinical applicability. RESULTS Among the 6,671 citations identified, we included 5 studies (n = 23,063 patients). The included studies described 5 unique multivariable prediction models generated through forward selection, backward selection, or Akaike Information Criterion-based methods. Two models were designed to predict any SSI and 3 Szyilagyi grade II (extending into subcutaneous tissue) SSI. Across the 5 models, 18 adjusted predictors (10 of which were preoperative, 3 intraoperative, and 5 postoperative) significantly predicted any SSI and 14 adjusted predictors significantly predict Szilagyi grade II SSI. Female sex, obesity, and chronic obstructive pulmonary disease significantly predicted SSI in more than one model. All models had a "good fit" according to the Hosmer-Lemeshow test (P > 0.05). Model discrimination was quantified using the area under the curve, which ranged from 0.66 to 0.75 across models. Two models were internally validated using non-exhaustive twofold cross-validation and bootstrap resampling. No model was externally validated. Three studies had a high overall risk of bias according to the Prediction model Risk Of Bias ASsessment Tool (PROBAST). CONCLUSIONS Five multivariable prediction models with moderate discrimination have been developed to forecast risk of SSI development after lower limb revascularization surgery. Given the frequency and consequences of SSI after these procedures, development and external validation of novel prediction models and comparison of these models to the existing models evaluated in this systematic review is warranted.

Risk Factors for Surgical Site Infection after Lower Limb Revascularisation Surgery: a Systematic Review and Meta-Analysis of Prognostic Studies. Eur J Vasc Endovasc Surg 2024; 67:455-467. [PMID: 37925099 DOI: 10.1016/j.ejvs.2023.10.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 09/27/2023] [Accepted: 10/30/2023] [Indexed: 11/06/2023]
Abstract
OBJECTIVE To systematically review and meta-analyse adjusted risk factors for surgical site infection (SSI) after lower limb revascularisation surgery. DATA SOURCES MEDLINE, Embase, Evidence Based Medicine Reviews, and the Cochrane Central Register of Controlled Trials (inception to 28 April 2022). REVIEW METHODS Systematic review and meta-analysis conducted according to PRISMA guidelines. After protocol registration, databases were searched. Studies reporting adjusted risk factors for SSI in adults who underwent lower limb revascularisation surgery for peripheral artery disease were included. Adjusted odds ratios (ORs) were pooled using random effects models. GRADE was used to assess certainty. RESULTS Among 6 377 citations identified, 50 studies (n = 271 125 patients) were included. The cumulative incidence of SSI was 12 (95% confidence interval [CI] 10 - 13) per 100 patients. Studies reported 139 potential SSI risk factors adjusted for a median of 12 (range 1 - 69) potential confounding factors. Risk factors that increased the pooled adjusted odds of SSI included: female sex (pooled OR 1.41, 95% CI 1.20 - 1.64; high certainty); dependent functional status (pooled OR 1.18, 95% CI 1.03 - 1.35; low certainty); being overweight (pooled OR 1.82, 95% CI 1.29 - 2.56; moderate certainty), obese (pooled OR 2.20, 95% CI 1.44 - 3.36; high certainty), or morbidly obese (pooled OR 1.65, 95% CI 1.08 - 2.52; moderate certainty); chronic obstructive pulmonary disease (pooled OR 1.42, 95% CI 1.17 - 1.71; high certainty); chronic limb threatening ischaemia (pooled OR 1.67, 95% CI 1.22 - 2.29; moderate certainty); chronic kidney disease (pooled OR 2.13, 95% CI 1.18 - 3.83; moderate certainty); intra-operative (pooled OR 1.23, 95% CI 1.02 - 1.49), peri-operative (pooled OR 1.92, 95% CI 1.27 - 2.90), or post-operative (pooled OR 2.21, 95% CI 1.44 - 3.39) blood transfusion (moderate certainty for all); urgent or emergency surgery (pooled OR 2.12, 95% CI 1.22 - 3.70; moderate certainty); vein bypass and or patch instead of endarterectomy alone (pooled OR 1.86, 95% CI 1.33 - 2.59; moderate certainty); an operation lasting ≥ 3 hours (pooled OR 1.86, 95% CI 1.33 - 2.59; moderate certainty) or ≥ 5 hours (pooled OR 1.60, 95% CI 1.18 - 2.17; moderate certainty); and early or unplanned re-operation (pooled OR 4.50, 95% CI 2.18 - 9.32; low certainty). CONCLUSION This systematic review identified evidence informed SSI risk factors following lower limb revascularisation surgery. These may be used to develop improved SSI risk prediction tools and to identify patients who may benefit from evidence informed SSI prevention strategies.

Abstract
OBJECTIVE Preventing untimely death in patients with peripheral artery disease (PAD) requires a detailed understanding of the predominant causes of death (COD). This literature review aims to describe how short- and long-term COD are reported in patients who had surgery for PAD. METHODS A literature review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines for articles reporting specific causes of mortality in patients who had surgery for all stages of PAD. Articles were included if they reported COD after open surgical or endovascular revascularisation, or major or minor amputation for PAD. Critical appraisals were conducted according to included study types, using the Joanna Briggs Institute tools. RESULTS Cause of death was reported in 21 publications. Twenty were observational and one was a randomised control trial. Study size ranged from 25 to 10,505 patients. Cardiovascular disease was the most prevalent COD in perioperative periods (42.5% from 13 studies). Long-term follow-up ranged from 1 month and 7 years with 15 studies reporting cardiac related mortality as the most frequent cause of death. However, mortality from neoplasia, respiratory disease (including pneumonia and pulmonary emboli), stroke and sepsis were prevalent. Many studies were low-average quality, with few population-based observational studies. CONCLUSION Whilst cardiovascular COD are the most prevalent reasons for mortality in patients with PAD, the proportion of patients dying from neoplasia and respiratory disease is high. Improved reporting standards for COD in studies examining PAD are needed.

Abstract
BACKGROUND The 5-factor frailty index (5-mFI), validated frailty index with Spearmen rho correlation of .95 and C statistic >.7 for predicting postoperative complications, can be preoperatively used to stratify patients prior to parastomal hernia repairs. METHODS Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database identified patients from 2015 to 2020. 5-mFI scores were calculated by adding one point for each comorbidity present: diabetes mellitus, congestive heart failure (CHF), hypertension requiring medication, severe chronic obstructive pulmonary disease (COPD), non-independent functional status. Primary endpoint was 30-day overall complications; secondary endpoints were 30-day readmission, reoperation, and discharge to care facility. RESULTS 2924 (52.2% female) patients underwent elective parastomal hernia repair. Univariate analysis showed 5-mFI > 2 had higher rates of overall (P = .008), pulmonary (P = .002), cardiovascular (P = .003)), hematologic (P = .003), and renal (P = .002) complications and higher rates of readmission (P = .009), reoperation (P = .001), discharge to care facility (P < .001), and death (P < .001). Multivariate analysis identified a 5-mFI of 2 or more as an independent risk factor for overall complications [OR: 1.40, 1.03-1.78; P = .032], pulmonary complications [2.97, 1.63-5.39; P < .001], hematological complications [1.60, 1.03-2.47; P = .035], renal complications [2.04, 1.19-3.46; P = .009], readmission [1.54, 1.19-1.99; P < .001], and discharge to facility [2.50, 1.66-3.77; P < .001]. Reoperation was not signification on multivariate analysis. CONCLUSIONS Parastomal hernia repair patients with 5-mFI score of >2 had higher risk of renal, cardiovascular, pulmonary, and hematologic complications, readmissions, longer hospitalization, discharge to care facility, and mortality, and can be useful during preoperative risk stratification.

Frail but Resilient: Frailty in Autologous Breast Reconstruction is Associated with Worse Surgical Outcomes but Equivalent Long-Term Patient-Reported Outcomes. Ann Surg Oncol 2024; 31:659-671. [PMID: 37864119 DOI: 10.1245/s10434-023-14412-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 09/19/2023] [Indexed: 10/22/2023]
Abstract
BACKGROUND Frailty is associated with higher risk of complications following breast reconstruction, but its impact on long-term surgical and patient-reported outcomes has not been investigated. We examined the association of the five-item modified frailty index (MFI) score with long-term surgical and patient-reported outcomes in autologous breast reconstruction. PATIENTS AND METHODS We conducted a retrospective cohort study of consecutive patients who underwent mastectomy and autologous breast reconstruction between January 2016 and April 2022. Primary outcome was any flap-related complication. Secondary outcomes were patient-reported outcomes and predictors of complications in the frail cohort. RESULTS We identified 1640 reconstructions (mean follow-up 24.2 ± 19.2 months). In patients with MFI ≥ 2, the odds of surgical [odds ratio (OR) 2.13, p = 0.023] and medical (OR 17.02, p < 0.001) complications were higher than in nonfrail patients. We found no significant difference in satisfaction with the breast (p = 0.287), psychosocial well-being (p = 0.119), or sexual well-being (p = 0.314) according to MFI score. Chronic obstructive pulmonary disease was an independent predictor of infection (OR 3.70, p = 0.002). Tobacco use (OR 7.13, p = 0.002) and contralateral prophylactic mastectomy (OR 2.36, p = 0.014) were independent predictors of wound dehiscence. Dependent functional status (OR 2.36, p = 0.007) and immediate reconstruction (compared with delayed reconstruction; OR 3.16, p = 0.026) were independent predictors of skin flap necrosis. Dependent functional status was also independently associated with higher odds of reoperation (OR 2.64, p = 0.011). CONCLUSION Frailty is associated with higher risk of complications in breast reconstruction, but there is no significant difference in long-term patient-reported outcomes. MFI should be considered in breast reconstruction to improve outcomes in high-risk frail patients.

ANNALS OF SURGERY OPEN 2023; 4:e348. [PMID: 38144491 PMCID: PMC10735122 DOI: 10.1097/as9.0000000000000348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 09/06/2023] [Indexed: 12/26/2023] Open
Abstract
Objective We investigated frailty's impact on traumatic subdural hematoma (tSDH), examining its relationship with major complications, length of hospital stay (LOS), mortality, high level of care discharges, and survival probabilities following nonoperative and operative management. Background Despite its frequency as a neurosurgical emergency, frailty's impact on tSDH remains underexplored. Frailty characterized by multisystem impairments significantly predicts poor outcomes, necessitating further investigation. Methods A retrospective study examining tSDH patients ≥18 years and assigned an abbreviated injury scale score ≥3, and entered into ACS-TQIP between 2007 and 2020. We employed multivariable analyses for risk-adjusted associations of frailty and our outcomes, and Kaplan-Meier plots for survival probability. Results Overall, 381,754 tSDH patients were identified by mFI-5 as robust-39.8%, normal-32.5%, frail-20.5%, and very frail-7.2%. There were 340,096 nonoperative and 41,658 operative patients. The median age was 70.0 (54.0-81.0) nonoperative, and 71.0 (57.0-80.0) operative cohorts. Cohorts were predominately male and White. Multivariable analyses showed a stepwise relationship with all outcomes P < 0.001; 7.1% nonoperative and 14.9% operative patients had an 20% to 46% increased risk of mortality, that is, nonoperative: very frail (HR: 1.20 [95% CI: 1.13-1.26]), and operative: very frail (HR: 1.46 [95% CI: 1.38-1.55]). There were precipitous reductions in survival probability across mFI-5 strata. Conclusion Frailty was associated with major complications, LOS, mortality, and high level care discharges in a nationwide population of 381,754 patients. While timely surgery may be required for patients with tSDH, rapid deployment of point-of-care risk assessment for frailty creates an opportunity to equip physicians in allocating resources more precisely, possibly leading to better outcomes.

Abstract
OBJECTIVE Frailty is common in vascular patients and is recognized for its prognostic value. In the absence of consensus, a multitude of frailty assessment tools exist. This systematic review aimed to quantify the variety in these tools and describe their content and application to inform future research and clinical practice. METHODS Multiple cross-disciplinary electronic literature databases were searched from inception to August 2022. Studies describing frailty assessment in a vascular surgical population were eligible. Data extraction to a validated template included patient demographics, tool content, and analysis methods. A secondary systematic search for papers describing the psychometric properties of commonly used frailty tools was then performed. RESULTS Screening 5358 records identified 111 eligible studies, with an aggregate population of 5,418,236 patients. Forty-three differing frailty assessment tools were identified. One-third of these failed to assess frailty as a multidomain deficit and there was a reliance on assessing function and presence of comorbidity. Substantial methodological variability in data analysis and lack of methodological description was also identified. Published psychometric assessment was available for only 4 of the 10 most commonly used frailty tools. The Clinical Frailty Scale was the most studied and demonstrates good psychometric properties within a surgical population. CONCLUSIONS Substantial heterogeneity in frailty assessment is demonstrated, precluding meaningful comparisons of services and data pooling. A uniform approach to assessment is required to guide future frailty research. Based on the literature, we make the following recommendations: frailty should be considered a continuous construct and the reporting of frailty tools' application needs standardized. In the absence of consensus, the Clinical Frailty Scale is a validated tool with good psychometric properties that demonstrates usefulness in vascular surgery.

Investigation of center-specific saphenous vein utilization rates in femoral popliteal artery bypass and associated impact of conduit on outcomes. J Vasc Surg 2023; 78:1497-1512.e3. [PMID: 37648090 PMCID: PMC10756644 DOI: 10.1016/j.jvs.2023.08.123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/14/2023] [Accepted: 08/19/2023] [Indexed: 09/01/2023]
Abstract
OBJECTIVE The purpose of this study is to investigate variation in great saphenous vein (GSV) use among the various centers participating in the Vascular Quality Initiative infrainguinal bypass modules. Further, differences in outcomes in femoral-popliteal artery bypass with single segment GSV conduit vs prosthetic conduit will be documented. Center GSV use rate impact on outcomes will be investigated. METHODS Primary exclusions were patients undergoing redo bypass, urgent or emergent bypass, and those in whom prosthetic graft was used while having undergone prior coronary artery bypass grafting. The distribution of GSV use across the 260 centers participating in Vascular Quality Initiative infrainguinal bypass module was placed into histogram and variance in mean GSV use evaluated with analysis of variance analysis. Centers that used GSV in >50% of bypasses were categorized as high use centers and centers that used the GSV in <30% of cases were categorized as low use centers. Baseline differences in patient characteristics and comorbidities in those undergoing bypass with GSV vs prosthetic conduit were analyzed with χ2 testing and the Student t test, as were those undergoing treatment in high vs low use centers. Multivariable time-dependent Cox regression analyses were then performed for the primary outcomes of major amputation ipsilateral to the operative side and mortality in long-term follow-up. High vs low use center was a dichotomous variable in these regressions. Secondary outcomes of freedom from graft infection and freedom from loss of primary patency were performed with Kaplan-Meier analysis. RESULTS Among centers with >50 patients meeting inclusion criteria for this study, GSV use ranged from 15% to 93% (analysis of variance P < .001). When considering all centers irrespective of number of patients, the range was 0% to 100%. On Kaplan-Meier analysis, GSV conduit use was associated with improved freedom from loss of primary or primary assisted patency, improved freedom from major amputation after index hospitalization, improved freedom from graft infection after the index hospitalization, and improved freedom from mortality in long-term follow-up (log-rank P < .001 for all four outcomes). Both low use center (hazard ratio, 1.35; P < .001) and prosthetic graft use (hazard ratio, 1.24; P < .001) achieved multivariable significance as risks for mortality in long-term follow-up. Other variables with a multivariable mortality association are presented in the manuscript. Low use center and prosthetic bypass were significant univariable but not multivariable risks for major amputation after index hospitalization. CONCLUSIONS There is remarkably wide variation in GSV use for femoral popliteal artery bypass among various medical centers. GSV use is associated with enhanced long-term survival as well as freedom from loss of bypass patency and graft infection. The data herein indicate institutional patterns of prosthetic conduit choice, which has the potential to be altered to enhance outcomes.

Association of Preoperative Frailty with Inferior Outcomes for Patients Undergoing Lower Extremity Bypass for Chronic Limb Threatening Ischemia: A Systematic Review. Ann Vasc Surg 2023; 97:320-328. [PMID: 37356656 DOI: 10.1016/j.avsg.2023.05.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 05/22/2023] [Accepted: 05/26/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Frailty is a risk factor associated with adverse postoperative outcomes following lower extremity bypass (LEB) surgery in patients with peripheral arterial disease (PAD). Chronic limb threatening ischemia (CLTI) represents the worst form of PAD, and frailty is common among patients presenting with CLTI. Multiple frailty assessment scores have been developed for the past 2 decades; however, a universal clinical assessment tool for measuring frailty has not yet been established due to the complexity of the concept. This systematic review aimed to evaluate the use of a frailty index as a predictor of postoperative outcomes in patients undergoing LEB. METHODS The review protocol was registered in the international prospective register of systematic reviews (PROSPERO) database (CRD42022358888). A systematic literature search was conducted using the PubMed and Scopus databases. The review followed the preferred reporting items for systematic reviews and metaanalyses (PRISMA) guidelines. The risk of bias was evaluated using the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool. A total of 3,929 studies were initially selected originally and were eventually left with 6 studies that met the inclusion criteria of this systematic review. RESULTS Six studies were examined that assessed the relationship between frailty index and long-term mortality following LEB for CLTI were screened. All analyses were published between 2017 and 2020 and included a broad spectrum of patients who underwent LEB. The results of these studies showed inconsistencies in the reporting of postoperative outcomes and the time endpoint of these events. However, all correlated with higher frailty index and increased mortality rate. CONCLUSIONS Higher frailty index preoperatively is associated with an increased likelihood of postoperative comorbidities after undergoing LEB. Identifying and addressing the preoperative frailty index of these patients may be a practical approach to reducing postoperative adverse outcomes. A thorough review of the frailty spectrum and standardized reporting of outcomes in the context of frailty could be helpful to have a more comprehensive understanding of this subject.

Preoperative Anemia is Associated with Poorer Postoperative Outcomes in Patients Undergoing Infrainguinal Bypass Surgery. Ann Vasc Surg 2023; 97:1-7. [PMID: 36641087 DOI: 10.1016/j.avsg.2023.01.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 01/01/2023] [Accepted: 01/02/2023] [Indexed: 01/13/2023]
Abstract
BACKGROUND Preoperative anemia is an important, modifiable risk factor among surgical patients. However, data are scarce on the impact of preoperative anemia on postoperative outcomes after infrainguinal bypass. METHODS In this multi-institutional analysis, data were retrospectively collected on all infrainguinal bypass procedures performed between 2010 and 2020. Patients were grouped by preoperative hemoglobin as per the National Cancer Institute anemia scale (mild, 10 g/dL-lower limit of normal; moderate, 8.0-9.9 g/dL; severe, 6.5-7.9 g/dL). Multivariable comparisons were performed using logistic regression analysis. RESULTS A total of 492 patients underwent bypass for peripheral artery disease over the 10-year study period. Median preoperative hemoglobin was 11.0 g/dL (interquartile range 9.5-12.7) and median follow-up was 1.7 years. Preoperative anemia was prevalent among bypass patients (mild 52.4% [n = 258], moderate 26.4% [n = 130], and severe 5.1% [n = 25]). Women were more likely to have moderate (49.2% [women] vs. 50.8% [men]) or severe anemia (52.0% [women] vs. 48.0% [men]) compared with normal hemoglobin (17.7% [women] vs. 82.3% [men]) (P < 0.001). Patients with preoperative anemia were more likely to present with tissue loss (22.8% [normal] vs. 47.7% [moderate] vs. 52.0% [severe], P = 0.01). Bypass target and conduit types were similar between groups. Anemic patients had longer median hospital length of stay compared with nonanemic patients (4 days [normal] vs. 5 days [mild] vs. 6 days [moderate] vs. 7 days [severe], P < 0.001). Postoperative mortality at 30 days was similar across anemia groups (2.5% [normal] vs. 4.6% [moderate] vs. 8.0% [severe], P = 0.23). On multivariable analysis, however, postoperative mortality was independently associated with severe anemia (odds ratio 7.5 [1.2-48.8], P = 0.04) and male gender (odds ratio 7.5 [1.2-26.4], P = 0.03). CONCLUSIONS Preoperative anemia is common among patients undergoing infrainguinal bypass surgery and is an independent risk factor for postoperative mortality. Future investigation is needed to determine whether correction of anemia improves postoperative outcomes in these high-risk patients.

[PMID: 37023923 DOI: 10.1016/j.avsg.2023.03.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 02/24/2023] [Accepted: 03/24/2023] [Indexed: 04/08/2023]
Abstract
BACKGROUND In recent years, there has been a tendency toward an "endovascular-first" approach for the treatment for femoropopliteal arterial disease. The purpose of this study is to determine if there are patients that are better served with an initial femoropopliteal bypass (FPB) rather than an endovascular attempt at revascularization. METHODS A retrospective analysis of all patients undergoing FPB between June 2006 - December 2014 was performed. Our primary endpoint was primary graft patency, defined as patent using ultrasound or angiography without secondary intervention. Patients with <1-year follow-up were excluded. Univariate analysis of factors significant for 5-year patency was performed using χ2 tests for binary variables. A binary logistic regression analysis incorporating all factors identified as significant by univariate analysis was used to identify independent risk factors for 5-year patency. Event-free graft survival was evaluated using Kaplan-Meier models. RESULTS We identified 241 patients undergoing FPB on 272 limbs. FPB indication was disabling claudication in 95 limbs, chronic limb-threatening ischemia (CLTI) in 148, and popliteal aneurysm in 29. In total, 134 FPB were saphenous vein grafts (SVG), 126 were prosthetic grafts, 8 were arm vein grafts, and 4 were cadaveric/xenografts. There were 97 bypasses with primary patency at 5 or more years of follow-up. Grafts patent at 5 years by Kaplan-Meier analysis were more likely to have been performed for claudication or popliteal aneurysm (63% 5-year patency) as compared with CLTI (38%, P < 0.001). Statistically significant predictors (using log rank test) of patency over time were use of SVG (P = 0.015), surgical indication of claudication or popliteal aneurysm (P < 0.001), Caucasian race (P = 0.019) and no history of COPD (P = 0.026). Multivariable regression analysis confirmed these 4 factors as significant independent predictors of 5-year patency. Of note, there was no statistical correlation between FPB configuration (above or below knee anastomosis, in-situ versus reversed saphenous vein) and 5-year patency. There were 40 FPBs in Caucasian patients without a history of COPD receiving SVG for claudication or popliteal aneurysm that had a 92% estimated 5-year patency by Kaplan-Meier survival analysis. CONCLUSIONS Long-term primary patency that was substantial enough to consider open surgery as a first intervention was demonstrated in Caucasian patients without COPD, having good quality saphenous vein, and who underwent FPB for claudication or popliteal artery aneurysm.

Ann Vasc Surg 2023; 96:261-267. [PMID: 37044241 DOI: 10.1016/j.avsg.2023.03.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 02/25/2023] [Accepted: 03/19/2023] [Indexed: 04/14/2023]
Abstract
BACKGROUND Endovascular interventions are performed routinely with minimal risk in younger populations. The safety and efficacy of endovascular interventions in nonagenarians is under examined. We sought to examine the following (1) mortality and limb salvage rates in the nonagenarian population and (2) whether frailty was associated with outcomes following lower extremity (LE) interventions for both acute limb ischemia (ALI) and chronic limb threatening ischemia (CLTI). METHODS A retrospective review of patients ≥90 years who underwent a LE angiogram for ALI or CLTI over a 12-year period at a single institution was performed. Primary outcomes were 30-day and 12-month limb salvage and mortality rates. Patient demographics, 30-day complications, and 12-month target vessel reintervention (TVR) were reviewed. Frailty scores were calculated using the 11-factor modified frailty index (MFI-11). RESULTS From 2009 to 2021, 76 patients (36% male) with a mean age of 93 (range: 90-102) underwent endovascular procedures for ALI (n = 13) and CLTI (n = 63). 30-day amputation and mortality rates were 6% and 8%, respectively. Patient demographics, preoperative functional status, and TVR rates were not different between patients who had early amputation (≤30 days) and those who achieved limb salvage. Seventy-two patients (94%) had follow-up data at 30 days. There was an 8% mortality rate at 30 days. Of those alive at 30 days, 94% of patients had successful limb salvage. Fifty-eight patients had complete follow-up data at 12 months. Of the patients alive at 12-month follow-up (75%), the limb salvage rate was 98%. Patients with amputation at 30 days had a significantly higher mortality rate at 12 months compared to those who did not (83% vs. 19%; P < 0.01). Based on MFI-11 scoring, 35% of the population was considered frail (≥0.27). Frail patients did not have significantly different 30-day outcomes (limb salvage: 94% vs. 88%; mortality 8% vs. 9%, P = 0.41 and 0.94, respectively) or 12-month outcomes (limb salvage: 82% vs. 94%; mortality: 32% vs. 22%, P = 0.28 and 0.39, respectively). CONCLUSIONS Endovascular procedures can be done safely in nonagenarians with low mortality and amputation rates. Patients with early amputation are at significantly higher risk of death at 12 months. Frailty, as measured by a validated index, was not associated with early or late outcomes. When compared to immediate amputation, nonagenarian patients and their families should be counseled as to the benefit from a minimally invasive endovascular procedure.

Abstract
This study aimed to investigate the frailty of patients with restenosis after percutaneous transluminal angioplasty (PTA) for peripheral arterial disease, explore the influencing factors, and determine its key factors to take targeted care measures and provide a basis for further interventional care. We recruited as many eligible subjects as possible and a total of 106 patients with restenosis after PTA for peripheral arterial disease in our hospital finished this study from January 2016 to August 2021. The Shorter 12-item version of health-related quality of life scale, Chinese Tilburg debility scale, Pittsburgh sleep quality index scale and activities of daily living score scale were used for investigation, and the independent influencing factors of patients' frailty were evaluated by multivariate logistic regression analysis. The incidence of frailty in restenosis after PTA was 72.6%. Logistic regression analysis found that high levels of C-reactive protein (odds ratios [OR] = 1.080, 95% confidence interval [CI] 1.012-1.153), diabetes (OR = 2.531, 95% CI 1.024-6.257) and advanced age (OR = 1.170, 95% CI 1.042-1.314) were risk factors for restenosis patients frailty, and higher scores of shorter 12-item version of health-related quality of life scale (OR = 0.889, 95% CI 0.813-0.973) was a protective factor for frailty in these patients. The incidence of debilitation in patients with restenosis after PTA for peripheral arterial disease is high, and high C-reactive protein levels, diabetes mellitus and advanced age are significantly associated with restenosis patients. Improving the quality of life of restenosis patients can reduce the occurrence of frailty.

A Meta-Analysis to Derive Population-Based Quality Benchmarks of the Incidence of Surgical Site Infection After Lower Limb Revascularization Surgery. Ann Vasc Surg 2023:S0890-5096(23)00509-5. [PMID: 37453466 DOI: 10.1016/j.avsg.2023.06.030] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 06/14/2023] [Accepted: 06/21/2023] [Indexed: 07/18/2023]
Abstract
OBJECTIVES The reported incidence of surgical site infection (SSI) after lower limb revascularization surgery varies. We conducted a systematic review and meta-analysis of population-based studies reporting the incidence of SSI in adults who underwent these surgeries in high-income countries to derive SSI quality benchmarks. METHODS We searched MEDLINE, EMBASE, CENTRAL, and Evidence-Based Medicine Reviews (inception-to-April 28th, 2022) for population-based studies estimating the cumulative incidence of SSI among adults who underwent lower limb revascularization surgery for peripheral artery disease (PAD) in high-income countries. Two investigators independently screened abstracts and full-text articles, extracted data, and assessed risks of bias. We used random-effects models to pool data and GRADE to assess certainty. RESULTS Among 6258 citations, we included 53 studies (n=757,726 patients); eight of which (n=435,769 patients) reported non-overlapping data that were meta-analyzed. The pooled cumulative incidence of any SSI was 6.0 in 100 patients [95% confidence interval (CI)=4.3-8.0 in 100 patients; n=8 studies; n=435,769 patients; moderate certainty]. The cumulative incidence of Szilagyi grade I (cellulitis), grade II (subcutaneous tissue), and grade III (prosthetic graft) SSI was 6.5 in 100 patients (95% CI=4.3-8.6 in 100 patients; n=2 studies; n=39,645 patients; low certainty), 2.1 in 100 patients (95% CI=2.0-2.3 in 100 patients; n=2 studies; low certainty), and 0.4 in 100 patients (95% CI=0.4-0.4 in 100 patients; n=1 study; n=333,275 patients; low certainty), respectively. The pooled cumulative incidence of any early (in-hospital/≤30-days) and late (>30-days) SSI was 6.2 in 100 patients (95% CI=4.4 to 8.0 in 100 patients; n=7 studies; n=431,273 patients; moderate certainty) and 3.7 in 100 patients (95% CI=2.2-5.2 in 100 patients; n=2 studies; n=10,565 patients; low certainty), respectively. CONCLUSIONS This systematic review derived population-based benchmarks of the incidence of any SSI; Szilagyi I, II, and III SSI; and early and late SSI after lower limb revascularization surgery. These may be used by practicing surgeons and healthcare leaders/administrators to guide quality improvement efforts in the United States and perhaps other countries.

Abstract
BACKGROUND Frailty predicts adverse perioperative outcomes and increased mortality in patients having vascular surgery. Frailty assessment is a potential tool to inform resource allocation, and shared decision-making about vascular surgery in the resource constrained COVID-19 pandemic environment. This cohort study describes the prevalence of frailty in patients having vascular surgery and the association between frailty, mortality and perioperative outcomes. METHODS The COVID-19 Vascular Service in Australia (COVER-AU) prospective cohort study evaluates 30-day and six-month outcomes for consecutive patients having vascular surgery in 11 Australian vascular units, March-July 2020. The primary outcome was mortality, with secondary outcomes procedure-related outcomes and hospital utilization. Frailty was assessed using the nine-point visual Clinical Frailty Score, scores of 5 or more considered frail. RESULTS Of the 917 patients enrolled, 203 were frail (22.1%). The 30 day and 6 month mortality was 2.0% (n = 20) and 5.9% (n = 35) respectively with no significant difference between frail and non-frail patients (OR 1.68, 95%CI 0.79-3.54). However, frail patients stayed longer in hospital, had more perioperative complications, and were more likely to be readmitted or have a reoperation when compared to non-frail patients. At 6 months, frail patients had twice the odds of major amputation compared to non-frail patients, after adjustment (OR 2.01; 95% CI 1.17-3.78), driven by a high rate of amputation during the period of reduced surgical activity. CONCLUSION Our findings highlight that older, frail patients, experience potentially preventable adverse outcomes and there is a need for targeted interventions to optimize care, especially in times of healthcare stress.

Abstract
BACKGROUND Microsurgical reconstruction is an integral part of plastic surgery. The 5-factor modified frailty index (5-mFI) is an effective tool to predict postoperative complications across multiple subspecialties. We aimed to determine if frailty scores using the 5-mFI can predict postoperative complications specifically in microvascular reconstruction. STUDY DESIGN Frailty scores were retrospectively assessed in microsurgical reconstruction patients (2012-2016) using the American College of Surgeons National Quality Improvement Program base. The 5 variables that comprise the 5-mFI are history of chronic obstructive pulmonary disease, history of congestive heart failure, functional status, hypertension requiring medication and diabetes. The data were analyzed using the Goodman test, χ2 test, and a logistic regression model. The congruence was also compared between the 5-mFI and the American Society of Anesthesiology (ASA) classification in predicting complications. RESULTS Of 5894 patients, the highest 5-mFI value was "3." Analyses show an increase in postoperative complications requiring ICU care. Further models indicate an association between readmission with hypertension and chronic obstructive pulmonary disease (P < 0.05). There was an increased risk of a failure to wean from ventilator with a history of chronic obstructive pulmonary disease and diabetes and an increased risk of readmission with a history of hypertension and chronic obstructive pulmonary disease. The 5-mFI and ASA were incongruent in predicting postoperative complications. CONCLUSIONS The 5-mFI predicts postoperative complications in the microsurgical reconstruction population. Although the 5-mFI and ASA predict different complications, their use provides insight into the potential adjustable risks before surgery.

Impact of frailty on all-cause mortality or major amputation in patients with lower extremity peripheral artery disease: A meta-analysis. Ageing Res Rev 2022; 79:101656. [PMID: 35654353 DOI: 10.1016/j.arr.2022.101656] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 04/15/2022] [Accepted: 05/27/2022] [Indexed: 12/19/2022]
Abstract
BACKGROUND Frailty has been increasingly identified as a risk factor of adverse outcomes in vascular disease. However, its impact on the survival and amputation in patients with lower extremity peripheral artery disease (PAD) remains controversial. This meta-analysis aimed to examine the value of frailty in predicting all-cause mortality or major amputation in patients with lower extremity PAD. METHODS PubMed, Embase, Web of Sciences, and Scopus databases (up to April 7, 2022) were comprehensively searched to identify relevant studies that investigated the association between frailty and all-cause mortality or major amputation in patients with lower extremity PAD. The impact of frailty on adverse outcomes was summarized by pooling the fully adjusted hazard ratio (HR) with 95% confidence intervals (CI) using a random effect (DerSimonian-Laird) model. RESULTS Seven studies reporting on eight articles that involved 122,892 patients were included. The prevalence of frailty ranged from 42% to 80% based on the frailty tool used. Meta-analysis showed that frailty was associated with an increased risk of 30-day all-cause mortality (HR 2.11; 95% CI 1.41-3.15; I2 =47.6%, p = 0.148, Tau-squared=0.058) and long-term all-cause mortality (HR 1.86; 95% CI 1.25-2.76; I2 =76.1%, p = 0.002, Tau-squared=0.118). However, no clear association was observed between frailty and major amputation (HR 1.07; 95% CI 0.83-1.36; I2 =23.0%, p = 0.273, Tau-squared=0.019). CONCLUSION Frailty independently predicts short and long-term all-cause mortality but not major amputation in patients with lower extremity PAD. Frailty status may play an important role in risk stratification of lower extremity PAD.

Abstract
Patients with widespread atherosclerosis such as peripheral artery disease (PAD) have a high risk of cardiovascular and limb symptoms and complications, which affects their quality of life and longevity. Over the past 2 decades there have been substantial advances in diagnostics, pharmacotherapy, and interventions including endovascular and open surgical to aid in the management of PAD patients. To summarize the evidence regarding approaches to diagnosis, risk stratification, medical and intervention treatments for patients with PAD, guided by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework, evidence was synthesized, and assessed for quality, and recommendations provided-categorized as weak or strong for each prespecified research question. Fifty-six recommendations were made, with 27% (15/56) graded as strong recommendations with high-quality evidence, 14% (8/56) were designated as strong recommendations with moderate-quality evidence, and 20% (11/56) were strong recommendations with low quality of evidence. Conversely 39% (22/56) were classified as weak recommendations. For PAD patients, strong recommendations on the basis of high-quality evidence, include smoking cessation interventions, structured exercise programs for claudication, lipid-modifying therapy, antithrombotic therapy with a single antiplatelet agent or dual pathway inhibition with low-dose rivaroxaban and aspirin; treatment of hypertension with an angiotensin converting enzyme or angiotensin receptor blocker; and for those with diabetes, a sodium-glucose cotransporter 2 inhibitor should be considered. Furthermore, autogenous grafts are more effective than prosthetic grafts for surgical bypasses for claudication or chronic limb-threatening ischemia involving the popliteal or distal arteries. Other recommendations indicated that new endovascular techniques and hybrid procedures be considered in patients with favourable anatomy and patient factors, and finally, the evidence for perioperative risk stratification for PAD patients who undergo surgery remains weak.

Ann Vasc Dis 2022; 15:165-174.

Abstract
Frailty is a well-known geriatric syndrome of impaired physiological reserve and increased vulnerability to stressors. Sarcopenia is also used as a parameter of physical impairment characterized by muscle weakness. As population aging has become more prominent in recent years, both modalities are now regarded as clinically important prognostic tools defined by multidimensional factors that may affect clinical outcomes in various clinical settings. A preoperative surgical risk analysis is mandatory to predict clinical and surgical outcomes in all surgical practices, particularly in high-risk surgical patients. In vascular surgical settings, frailty and sarcopenia have been accepted as useful prognostic tools to evaluate patient characteristics before surgery, as these may predict perioperative clinical and surgical outcomes. Although minimally invasive surgical approaches, such as endovascular therapy, and hybrid approaches have been universally developed, achieving good vascular surgical outcomes for high-risk cohorts remains to be challenge due to the increasing prevalence of elderly patients and multiple preoperative co-morbidities in addition to frailty and sarcopenia. Therefore, to further improve clinical and surgical outcomes, these preoperative geriatric prognostic factors will be of great importance and interest in vascular surgical settings for both physicians and surgeons.

Abstract
INTRODUCTION Frailty can be quantified using an index score to effectively predict surgical outcomes and complications. The modified frailty index (mFI) score includes 5 patient-specific medical history comorbidities including diabetes mellitus, congestive heart failure, hypertension, chronic obstructive pulmonary disease/pneumonia, and nonindependent functional status. The purpose of our study was to apply the 5-item mFI score to predict and minimize complications in patients undergoing breast reconstruction. METHODS The National Surgical Quality Improvement Program was queried for all patients undergoing primary breast reconstruction from 2016 to 2018. Patients were divided based on timing of reconstruction and type of reconstruction: immediate or delayed, and implant based or autologous based. A validated modified fragility score was applied to all patients. Patients were stratified by mFI scores of 0 (no comorbidities), 1 (1 comorbidity), and 2+ (2 or more comorbidities). Patient demographics and 30-day complications rates were recorded. RESULTS A total of 22,700 patients were identified. There were 10,673 patients who underwent immediate breast reconstruction, and 12,027 patients who underwent delayed breast reconstruction. A total of 14,159 patients underwent implant-based, and 8541 underwent autologous-based reconstruction. A total of 16,627 patients had an mFI score of 0, 4923 had a mFI score of 1, and 1150 had a mFI score of 2+. Compared with patients with an mFI score of 0, patients with an mFI score of 2 or greater were more likely to develop a postoperative complication (7.2 vs 12.3; P < 0.0001). Patients undergoing immediate reconstruction were more likely to develop a postoperative complications for every mFI category. The most common complications were wound and hematologic related. CONCLUSION Patients with higher mFI scores are likely to have an increase in postoperative complications after breast reconstruction. Increasing body mass index increases postoperative complications independent of frailty index scores. Patients with increasing frailty index scores undergoing immediate breast reconstruction have a significantly higher risk of postoperative complications compared with delayed reconstruction.Patients with increasing frailty index scores undergoing autologous breast reconstruction have a significantly higher risk of postoperative complications compared with implant-based reconstruction. High frailty index scores are associated with a higher risk of postoperative complications, reoperation rates, and readmission rates. Patients with higher mFI scores may benefit from a delayed implant-based reconstruction.

Abstract
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.

Abstract
OBJECTIVE To describe and critique tools used to assess frailty in vascular surgery patients, and investigate its associations with patient factors and outcomes. BACKGROUND Increasing evidence shows negative impacts of frailty on outcomes in surgical patients, but little investigation of its associations with patient factors has been undertaken. METHODS Systematic review and meta-analysis of studies reporting frailty in vascular surgery patients (PROSPERO registration: CRD42018116253) searching Medline, Embase, CINAHL, PsycINFO, and Scopus. Quality of studies was assessed using Newcastle-Ottawa scores (NOS) and quality of evidence using Grading of Recommendations Assessment, Development, and Evaluation criteria. Associations of frailty with patient factors were investigated by difference in means (MD) or expressed as risk ratios (RRs), and associations with outcomes expressed as odds ratios (ORs) or hazard ratios (HRs). Data were pooled using random-effects models. RESULTS Fifty-three studies were included in the review and only 8 (15%) were both good quality (NOS ≥ 7) and used a well-validated frailty measure. Eighteen studies (62,976 patients) provided data for the meta-analysis. Frailty was associated with increased age [MD 4.05 years; 95% confidence interval (CI) 3.35, 4.75], female sex (RR 1.32; 95% CI 1.14, 1.54), and lower body mass index (MD -1.81; 95% CI -2.94, -0.68). Frailty was associated with 30-day mortality [adjusted OR (AOR) 2.77; 95% CI 2.01-3.81), postoperative complications (AOR 2.16; 95% CI 1.55, 3.02), and long-term mortality (HR 1.85; 95% CI 1.31, 2.62). Sarcopenia was not associated with any outcomes. CONCLUSION Frailty, but not sarcopenia, is associated with worse outcomes in vascular surgery patients. Well-validated frailty assessment tools should be preferred clinically, and in future research.

Abstract
BACKGROUND Frailty is associated with worse outcomes across a variety of neurosurgical diseases. However, its effect on acute subdural hemorrhage (aSDH) outcomes is unclear. The goal of this study is to compare 3 measures of frailty with the gold standard (i.e., initial Glasgow Coma Scale [iGCS] score) for predicting outcomes after aSDH. METHODS Patients who presented between January 2016 and June 2018 were retrospectively identified based on International Classification of Diseases codes for aSDH. Patients' modified Frailty Index (mFI), temporalis muscle thickness (TMT), and age-adjusted Charlson Comorbidity Index (CCI) were calculated. Primary end points were death and discharge home. RESULTS Of 167 patients included, the mean age was 63.4 ± 1.9 years, the average CCI was 3.4 ± 0.2, mFI was 1.4 ± 0.1, TMT was 7.1 ± 0.2 mm, and iGCS score was 11.9 ± 0.3. Sixty-nine patients (41.3%) were discharged home and 32 (19.2%) died during hospitalization. In multivariate analysis, decreasing iGCS score (odds ratio [OR], 0.84; 95% confidence interval [CI], 0.74-0.96; P = 0.0112) and midline shift (OR, 1.27; 95% CI, 1.08-1.50; P = 0.0048), but not age or frailty, predicted mortality. In addition to iGCS score (OR, 1.26; 95% CI, 1.10-1.44; P = 0.0011), lower CCI (OR, 0.32; 95% CI, 0.14-0.74; P = 0.0071) and larger TMT (OR, 2.63; 95% CI, 1.16-5.99; P = 0.0210) independently predicted increased rates of discharge home. mFI was not independently associated with either primary end point in multivariate analysis. CONCLUSIONS iGCS score predicts both mortality and discharge location after aSDH better than do age or frailty. However, CCI and TMT, but not mFI, are useful prognostic indicators of discharge to home after aSDH. The iGCS score should continue to be the primary prediction tool for patients with aSDH; however, frailty may be useful for resource allocation, especially when nearing discharge.
