[PMID: 37356651 DOI: 10.1016/j.avsg.2023.05.042] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/22/2023] [Accepted: 05/22/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Elective endovascular abdominal aortic aneurysm repair (EVAR) can be performed safely with a short postoperative length of stay (LOS). We aimed to develop and assess the impact of an enhanced recovery protocol (ERP) on LOS after elective EVAR. METHODS Pre-ERP development single center retrospective review of elective EVAR procedures from January 2012 to December 2019. ERP was developed by targeting factors associated with prolonged LOS (>2 days) elucidated from semistructured interviews and Bayesian additive regression tree analysis. Post-ERP development, a subsequent retrospective review of elective EVAR performed from January 2018 to June 2021 was performed to evaluate LOS before and after ERP. Primary outcome was LOS. RESULTS Two hundred sixteen patients underwent elective infrarenal EVAR from 2012 to 2019. Periprocedural factors identified as associated with LOS >2 days included noncommercial insurance (43.6% vs. 26.5%; P = 0.01), preoperative anemia (hemoglobin 12.56 g/dL vs. 13.57 g/dL; P = 0.001), worse renal function (creatinine 1.31 mg/dL vs. 1.01/dL; P = 0.004), open femoral access (74.4% vs. 26.5%; P < 0.001), intensive care unit (ICU) stay (2.7 days vs. 0.9 days; P < 0.001), postoperative anemia (9.8 g/dL vs. 11.9 g/dL; P < 0.001), postoperative creatinine (1.55 mg/dL vs. 0.97 mg/dL; P < 0.001), and beta blocker need on discharge (45.5% vs. 25%; P = 0.003) as significant between patients with short and prolonged LOS groups. Semistructured interviews revealed postoperative day 1 complete blood count/chemistry, postoperative physical therapy evaluation, ICU admission, urinary retention, patient expectations, and unavailability of transportation home as modifiable factors that delayed early discharge. A 14-component ERP was created to target the factors identified from combined qualitative and quantitative results. Post-ERP development, 74 elective EVAR patients were reviewed from 2018 to 2021 (37 pre-ERP and 37 post-ERP). Following ERP development, the mean LOS was reduced from 2.6 (standard deviation: 1.9) to 1.3 days (standard deviation: 1.3); P < 0.01. There were no significant differences in 30-day readmission, postoperative complications, emergency room visits, or 90-day mortality before and after the ERP was used. CONCLUSIONS Practice and procedural factors can be modified through an informed and safe process to reduce LOS after elective EVAR. LOS following elective EVAR was safely reduced following the use of a systematically developed ERP.

J Vasc Surg 2023; 77:415-423.e1. [PMID: 36100032 DOI: 10.1016/j.jvs.2022.09.003] [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: 05/28/2022] [Revised: 08/08/2022] [Accepted: 09/02/2022] [Indexed: 01/25/2023]
Abstract
OBJECTIVE Chronic kidney disease (CKD) and end-stage renal disease are traditionally associated with worse outcomes after endovascular and open repair of abdominal aortic aneurysm (AAA). This study stratifies outcomes of AAA repair by approach, CKD severity, and dialysis dependence. METHODS All patients undergoing elective infrarenal open aneurysm repair (OAR) and endovascular aortic repair (EVAR) with preoperative renal function data captured by the Vascular Quality Initiative between January 2003 and September 2020 were analyzed. Patients were stratified by CKD class as follows: CKD stages 1 and 2, CKD stage 3a, CKD stage 3b, CKD stages 4 and 5, and dialysis. Primary outcomes were perioperative and 1-year mortality. Predictors of survival were identified by Cox multivariate regression models. RESULTS In total, 53,867 elective AAA repairs were identified: 5396 (10%) OARs and 48,471 (90%) EVARs. Most patients were White (90%) and male (81%), with a mean age of 73 ± 9 years. Patients who underwent EVAR were older and had more comorbidities. The use of elective EVAR for AAA increased from 52% in 2003 to 91% in 2020 (P < .001). The OAR cohort had more perioperative complications and short-term mortality. The CKD 1 and 2 group had the highest 1-year survival compared with the other groups after both OAR and EVAR. On Cox regression analysis, after EVAR, compared with CKD 1 and 2, worsening CKD stage (CKD 3a: hazard ratio [HR], 1.25; 95% confidence interval [CI], 0.93-1.68; P = .13; CKD 3b: HR, 1.74; 95% CI, 1.23-2.45; P < .050; CKD 4-5: HR, 3.23; 95% CI, 2.13-4.88; P < .001), and dialysis (HR, 4.48; 95% CI, 1.90-10.6; P < .001) were independently associated with worse 1-year survival rates. After OAR, compared with CKD 1 and 2, worsening CKD stage (CKD 3a: HR, 1.08; 95% CI, 0.96-1.20; P = .20; CKD 3b: HR, 1.60; 95% CI, 1.41-1.81; P < .001; CKD 4-5: HR, 2.85; 95% CI, 2.39-3.41; P < .001), and dialysis (HR, 3.79; 95% CI, 3.01-4.76; P < .001) were independently associated with worse 1-year survival rates. CONCLUSIONS Regardless of the treatment approach, CKD severity is an important predictor of perioperative and 1-year mortality rates after infrarenal AAA repair and may reflect the natural history of CKD. Open repair is associated with high perioperative mortality risk in patients with CKD stages 4 and 5, as well as end-stage renal disease. Individualization of patient decision-making is especially important in patients with a glomerular filtration rate of less than 45 and perhaps consideration should be given to raising the threshold for elective AAA repair in these patients. Further studies focusing on appropriate size threshold for repair in these patients may be warranted.

Abstract
OBJECTIVE To describe the long-term reintervention rate after endovascular abdominal aortic aneurysm repair (EVR), and identify factors predicting reintervention. SUMMARY OF BACKGROUND DATA EVR is the most common method of aneurysm repair in America, and reintervention after EVR is common. Clinical factors predicting reintervention have not been described in large datasets with long-term follow-up. METHODS We studied patients who underwent EVR using the Vascular Quality Initiative registry linked to Medicare claims. Our primary outcome was reintervention, defined as any procedure related to the EVR after discharge from the index hospitalization. We used classification and regression tree modeling to inform a multivariable Cox-regression model predicting reintervention after EVR. RESULTS We studied 12,911 patients treated from 2003 to 2015. Mean age was 75.5 ± 7.3 years, 79.9% were male, and 89.1% of operations were elective. The 3-year reintervention rate was 15%, and the 10-year rate was 33%. Five factors predicted reintervention: operative time ≥3.0 hours, aneurysm diameter ≥6.0 cm, an iliac artery aneurysm ≥2.0 cm, emergency surgery, and a history of prior aortic surgery. Patients with no risk factors had a 3-year reintervention rate of 12%, and 10-year rate of 26% (n = 7310). Patients with multiple risk factors, such as prior aortic surgery and emergent surgery, had a 3-year reintervention rate 72%, (n = 32). Modifiable factors including EVR graft manufacturer or supra-renal fixation were not associated with reintervention (P = 0.76 and 0.79 respectively). CONCLUSIONS All patients retain a high likelihood of reintervention after EVR, but clinical factors at the time of repair can predict those at highest risk.

Abstract
OBJECTIVE Significant debate exists among providers who perform endovascular abdominal aortic aneurysm repair (EVAR) regarding the renal function change between suprarenal (SuF) and infrarenal (InF) fixation devices. The purpose of this study is to review our institution's experience using these devices in terms of renal function. METHODS This is a retrospective review of all elective EVARs performed within a three-site health system (Florida, Minnesota, and Arizona) during the period of 2000 to 2018. The primary outcome was renal function decline on long-term follow-up depending on the anatomical fixation of the device (SuF vs InF). Secondary outcomes were length of hospitalization (LOH) and progression to hemodialysis. Multivariable regression analysis was performed to test for associations affecting LOH. RESULTS There were 1130 elective EVARs included in our review. Of those, 670 (59.3%) had SuF and 460 (40.7%) InF. Long-term follow-up was 4.8 ± 3.7 years, and the rate of change in creatinine and estimated glomerular filtration rate (eGFR) were not statistically significant among groups (SuF vs InF). LOH was higher in those individuals with a SuF device (3.4 ± 2.2 vs 2.3 ± 1.0 days; P < .001). Ten patients with chronic kidney disease progressed to hemodialysis at 6.7 ± 3.8 years from EVAR. On Kaplan-Meier analysis, patients with chronic kidney disease with SuF were more likely to progress to hemodialysis (P = .039). On multivariable regression, female sex (Coef, 2.4; 95% confidence interval [CI], 0.17-0.41; P = .02), SuF (Coef, 9.5; 95% CI, 0.11-1.11; P < .0001), and intraoperative blood loss of greater than 150 mL (Coef, 15.4; 95% CI, 0.11-1.76; P < .0001) were predictors of prolonged LOH. CONCLUSION Our three-site, single-institution data indicate that, although the starting eGFR was statistically lower in those individuals undergoing elective EVAR with InF, device fixation type did not affect the creatinine and eGFR on long-term follow-up. However, caution should be exercised at the time of abdominal aortic aneurysm repair in those individuals who already presented with renal dysfunction.

The Need for Accurate Risk Assessment in a High-Risk Patient Population: A NSQIP Study Evaluating Outcomes of Cholecystectomy in the Patient With Cancer. J Surg Res 2020; 257:519-528. [PMID: 32919342 DOI: 10.1016/j.jss.2020.07.078] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 06/18/2020] [Accepted: 07/11/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Cholecystectomy is considered a low-risk procedure with proven safety in many high-risk patient populations. However, the risk of cholecystectomy in patients with active cancer has not been established. METHODS The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was queried to identify all patients with disseminated cancer who underwent cholecystectomy from 2005 to 2016. Postcholecystectomy outcomes were defined for patients with cancer and those without by comparing several outcomes measures. A multivariate model was used to estimate the odds of 30-d mortality. RESULTS We compared outcomes in 3097 patients with disseminated cancer to a matched cohort of patients without cancer. Patients with cancer had more comorbidities at baseline: dyspnea (10.5% versus 7.0%, P < 0.0001), steroid use (10.1% versus 3.0%, P < 0.0001), and loss of >10% body weight in 6-mo prior (9.3% versus 1.6%, P < 0.0001). Patients with cancer sustained higher rates of wound (2.3% versus 5.6%, P < 0.0001), respiratory (1.4% versus 3.9%, P < 0.0001), and cardiovascular (2.0% versus 6.8%, P < 0.0001) complications. In addition, patients with disseminated cancer experienced a longer length of stay and higher 30-d mortality. Multivariate modeling showed that the odds of 30-d mortality was 3.3 times greater in patients with cancer. CONCLUSIONS Compared to patients without cancer, those with disseminated cancer are at higher risk of complication and mortality following cholecystectomy. Traditional treatment algorithms should be used with caution and care decisions individualized based on the patient's disease status and treatment goals.

Abstract
Objectives The average hospital length of stay plays a significant role in healthcare costs, and is also used as a metric of hospital efficiency. An advantage of endovascular abdominal aortic aneurysm repair (EVAR) is the shorter postoperative time period after the surgery. The purpose of this study is to review the factors associated with increased length of stay after EVAR. Methods The records from American College of Surgeons National Quality Improvement Program (ACS-NSQIP) database in 2013 were obtained using Procedure Participant User File. Pre-, intra-, and post-operative factors were assessed of patients undergoing EVAR in 2013. Multivariable logistic regression analysis was used to identify independent variables for a hospital length of stay of at least seven days. Results A total of 1,991 patients (18.7% female, 81.3% males) underwent EVAR in 2013. Among these patients, 223 (11.2%) had a hospital stay greater than seven days. Variables significantly associated with length of stay in a multivariable model included: total operation time greater than 180 minutes (vs. less than 90 minutes, OR 1.88, CI 1.03-3.41, p = 0.039), postoperative, and intraoperative transfusions (OR 2.60, CI 1.66-4.08, p < 0.001), return to operating room (OR 2.88, CI 1.55-5.38, p < 0.001), rupture indication for surgery (OR 5.59, CI 3.18-9.83, p < 0.001), myocardial infarction (OR 5.85, CI 2.22-15.43, p < 0.001), preoperative transfusion (OR 13.05, CI 4.26-39.99, p < 0.001), and on ventilator greater than 48 hours (OR 49.65, CI 10.72-230.07, p < 0.001). Conclusions Multiple factors affect length of hospital stay in patients who have undergone EVAR. Patients with postoperative respiratory failure after EVAR have a significantly higher risk for longer hospital stays.

Abstract
INTRODUCTION Penectomy for PC is useful in staging, disease prognosis, and treatment. Limited studies have evaluated its surgical complications. We sought to assess these complications and determine predictive models to create a novel risk score for penectomy complications. PATIENTS AND METHODS A retrospective review of patients undergoing PC surgical management from the 2005-2016 American College of Surgeons National Surgical Quality Improvement Program was performed. Data were queried for partial and total penectomy among those with PC. To develop predictive models of complications, we fit LASSO logistic, random forest, and stepwise logistic models to training data using cross-validation, demographic, comorbidity, laboratory, and wound characteristics as candidate predictors. Each model was evaluated on the test data using receiver operating characteristic curves. A novel risk score was created by rounding coefficients from the LASSO logistic model. RESULTS A total of 304 cases met the inclusion criteria. Overall incidence of penectomy complications was 19.7%, where urinary tract infection (3.0%), superficial surgical site infection (3.0%), and bleeding requiring transfusion (3.9%) were most common. LASSO logistic, random forest, and stepwise logistic models for predicting complications had area under the curve (AUC) [95% confidence interval] values of 0.66 [0.52-0.81], 0.73 [0.63-0.83], and 0.59 [0.45-0.74], respectively. Eleven variables were included in the risk score. The LASSO model-derived risk score had moderately good performance (area under the curve [95% confidence interval] 0.74 [0.66-0.82]). Using a cutoff point of 6, the score attains sensitivity 0.58, specificity 0.74, and kappa 0.26. CONCLUSION PC management through penectomy is associated with appreciable complications rates. Predictive models of penectomy complications performed moderately well. Our novel prognostic risk score may allow for improved preoperative counseling and risk stratification of men undergoing surgical management of PC.

Length of Stay after Thoracic Endovascular Aortic Repair Depends on Indication and Acuity. Ann Vasc Surg 2018; 55:157-165. [PMID: 30217710 DOI: 10.1016/j.avsg.2018.06.027] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 05/07/2018] [Accepted: 06/30/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Length of stay (LOS) is a commonly used metric to optimize value in medical care. Although pathways have been developed for some procedures in vascular surgery to reduce LOS, they do not yet exist for thoracic endovascular aortic repair (TEVAR). The purpose of this study is to identify and define the risk factors for prolonged LOS in patients undergoing TEVAR to facilitate pathway development. METHODS We included TEVAR patients in the National Surgical Quality Improvement Program database from 2005 to 2015. Prolonged LOS was defined as LOS > 75th percentile of the overall cohort (11 days). Because initial analysis revealed the distinct clinical differences between dissection and aneurysm patients, further analysis was stratified by aortic pathology. Student's t-test and Chi-square tests were used to compare demographic and perioperative variables between dissection and aneurysm patients, respectively. Multivariable logistic regression was used to evaluate the predictors for prolonged LOS. RESULTS A total of 3,021 patients underwent TEVAR, with 858 patients (28.4%) undergoing TEVAR for dissection and 2,163 (71.6%) undergoing TEVAR for aneurysm. An initial analysis with logistic regression identified dissection indication (odds ratio [OR], 2.87; 95% confidence interval [CI], 1.1-7.3) as an independent predictor of prolonged LOS. Further analysis for prolonged LOS was subsequently performed separating dissection and aneurysm patients. Aneurysm patients were older (71.2 ± 11.7 vs. 63.1 ± 13.6 years, P < 0.001), more often Caucasian (76.8% vs. 61.8%, P < 0.001), and had more medical comorbidities (chronic obstructive pulmonary disease, cardiac history, diabetes, peripheral vascular disease, transient ischemic attack [TIA], P < 0.001). In contrast, dissection patients had higher American Society of Anesthesiology (ASA) classification score (58.5% had >3 ASA vs. 45.5%, P < 0.001), longer hospitalizations (10.2 ± 9.3 vs. 8.5 ± 10.4 days, P < 0.001), were more likely to have been transferred from another hospital or emergency room (58.4% vs. 48.3%, P < 0.001), and were more often emergent (32.4% vs. 15.4%, P < 0.001). In dissection patients, ASA classification score (OR, 1.49; 95% CI, 1.1-2.1) and dialysis (OR, 1.98; 95% CI, 1.0-3.9) were independent predictors for prolonged LOS. In aneurysm patients, dependent functional status (OR, 2.03; 95% CI, 1.4-2.8), diabetes (OR, 1.75; 95% CI, 1.1-2.8), cardiac history (OR, 1.37; 95% CI, 1.0-1.9), emergency status (OR, 1.98; 95% CI, 1.4-2.8), and dialysis (OR, 2.08; 95% CI, 1.2-3.7) predicted prolonged LOS. Postoperative complications including stroke/TIA; failure to wean from ventilator, sepsis, and pneumonia; and need for reoperation similarly increased LOS in both dissection and aneurysm patients. CONCLUSIONS Dissection and aneurysm patients undergoing TEVAR are comprised of different patient populations, with dissection patients more often enduring prolonged hospitalizations. In contrast, TEVAR performed for nonemergent aneurysm repair had the shortest LOS. These data support the development of separate pathways defined by indication and acuity for patients undergoing TEVAR.
