Predictors of prolonged length of stay after elective carotid revascularization. J Vasc Surg 2024:S0741-5214(24)01201-1. [PMID: 38763455 DOI: 10.1016/j.jvs.2024.05.022] [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: 03/13/2024] [Revised: 05/12/2024] [Accepted: 05/14/2024] [Indexed: 05/21/2024]
Abstract
OBJECTIVE Postoperative day-one discharge is used as a quality-of-care indicator after carotid revascularization. This study identifies predictors of prolonged length of stay (pLOS), defined as a postprocedural LOS of >1 day, after elective carotid revascularization. METHODS Patients undergoing carotid endarterectomy (CEA), transcarotid artery revascularization (TCAR), and transfemoral carotid artery stenting (TFCAS) in the Vascular Quality Initiative between 2016 and 2022 were included in this analysis. Multivariable logistic regression analysis was used to identify predictors of pLOS, defined as a postprocedural LOS of >1 day, after each procedure. RESULTS A total of 118,625 elective cases were included. pLOS was observed in nearly 23.2% of patients undergoing carotid revascularization. Major adverse events, including neurological, cardiac, infectious, and bleeding complications, occurred in 5.2% of patients and were the most significant contributor to pLOS after the three procedures. Age, female sex, non-White race, insurance status, high comorbidity index, prior ipsilateral CEA, non-ambulatory status, symptomatic presentation, surgeries occurring on Friday, and postoperative hypo- or hypertension were significantly associated with pLOS across all three procedures. For CEA, additional predictors included contralateral carotid artery occlusion, preoperative use of dual antiplatelets and anticoagulation, low physician volume (<11 cases/year), and drain use. For TCAR, preoperative anticoagulation use, low physician case volume (<6 cases/year), no protamine use, and post-stent dilatation intraoperatively were associated with pLOS. One-year analysis showed a significant association between pLOS and increased mortality for all three procedures; CEA (hazard ratio [HR],1.64; 95% confidence interval [CI], 1.49-1.82), TCAR (HR,1.56; 95% CI, 1.35-1.80), and TFCAS (HR, 1.33; 95%CI, 1.08-1.64) (all P < .05). CONCLUSIONS A postoperative LOS of more than 1 day is not uncommon after carotid revascularization. Procedure-related complications are the most common drivers of pLOS. Identifying patients who are risk for pLOS highlights quality improvement strategies that can optimize short and 1-year outcomes of patients undergoing carotid revascularization.

Abstract
Background Previous studies indicate an inverse relationship between hospital volume and mortality after carotid endarterectomy. However, data at the level of Brazil are lacking. Objectives To assess the relationship between hospital carotid endarterectomy procedure volumes and mortality in the state of São Paulo. Methods Data from the São Paulo State Hospital Information System on all carotid endarterectomies performed between 2015 and 2019 were analyzed. Hospitals were categorized into clusters by annual volume of surgeries (1-10, 11-25, and ≥26). Multiple logistic regression models were used to determine whether the volume of carotid endarterectomy procedures was an independent predictor of in-hospital mortality among patients undergoing this procedure. Results Crude in-hospital mortality was nearly 60 percent lower in patients who underwent carotid endarterectomy at the highest volume hospitals than among those who underwent endarterectomy at the lowest volume hospitals (unadjusted OR of survival to hospital discharge, 2.41; 95% CI, 1.11-5.23; p = 0.027). Although this lower rate represents 1.5 fewer deaths per 100 patients treated, high-volume centers are more likely than low-volume centers to perform elective procedures, thus the analysis did not retain statistical significance when adjusted for admission character (OR, 1.69; 95% CI, 0.74-3.87; p = 0.215). Conclusions In a contemporary Brazilian registry, higher volume carotid endarterectomy centers were associated with lower in-hospital mortality than lower volume centers. Further studies are needed to verify this relationship considering the presence of symptoms in patients.

Abstract
BACKGROUND Length of stay (LOS) and readmissions are common measures to evaluate quality of health care. The objective of this study was to evaluate factors related to hospital LOS and readmission within 90 days following carotid endarterectomy (CEA) in patients who have not had a stroke. METHODS Using a single institution database, patients who underwent CEA for carotid stenosis between 2014 and 2019 were identified. Asymptomatic carotid stenosis (no history of any stroke or transient ischemic attack (TIA) within 6 months prior to CEA), and patients who had a TIA without stroke were included. Demographic and perioperative factors were collected. Primary outcomes analyzed were increased LOS (>1 day) and readmission within 90 days after surgery. RESULTS There were 125 patients identified who underwent CEA for 133 carotid stenosis, and 8 patients had bilateral CEA; of which 36.8% were asymptomatic carotid stenosis with the remaining being operated on for TIA without any stroke. The mean age was 68 years old and 36.1% of cases were female. The median postoperative LOS was 2 days. Increased LOS occurred in 81 cases (60.9%). Increased LOS, compared to no increased LOS, occurred more often in patients with diabetes (48.1% vs. 30.8%, P = 0.047), in those with operations starting after 12:00 pm (45.7% vs. 21.2%, P = 0.004) and those with any minor complications such as neck swelling, neck pain, and urinary retention (30.9% vs. 15.4%, P = 0.044). Readmission within 90 days after CEA occurred in 24 (18%) of cases. Readmission within 90 days, compared to no readmission within 90 days, occurred more often in patients with a history of coronary artery disease (58.3% vs. 27.5%, P = 0.004), congestive heart failure (37.5% vs. 11%, P = 0.001), and atrial fibrillation (29.2% vs. 8.3%, P = 0.004). CONCLUSIONS More than half of patients undergoing CEA for carotid stenosis were discharged after postoperative day 1. Interventions on modifiable clinical risk factors, such as morning CEA scheduling and management of comorbidities, may decrease LOS and 90-day readmission rates.

Abstract
INTRODUCTION The objective of this study is to create a predictive model of prolonged postoperative length of stay (PLOS) in patients undergoing anatomic lung resection, to validate it in an external series and to evaluate the influence of PLOS on readmission and 90-day mortality. METHODS All patients registered in the GEVATS database discharged after the intervention were included. We define PLOS as the postoperative stay in days above the 75th percentile of stay for all patients in the series. A univariate and multivariate analysis was performed using logistic regression and the model was validated in an external cohort. The possible association between PLOS and readmission and mortality at 90 days was analyzed. RESULTS 3473 patients were included in the study. The median postoperative stay was 5 days (IQR: 4-7). 815 patients had PLOS (≥8 days), of which 79.9% had postoperative complications. The final model included as variables: age, BMI, male sex, ppoFEV1%, ppoDLCO% and thoracotomy; the AUC in the referral series was 0.684 (95% CI: 0.661-0.706) and in the validation series was 0.73 (95% CI: 0.681-0.78). A significant association was found between PLOS and readmission (p < .000) and 90-day mortality (p < .000). CONCLUSIONS The variables age, BMI, male sex, ppoFEV1%, ppoDLCO% and thoracotomy affect PLOS. PLOS is associated with an increased risk of readmission and 90-day mortality. 20% of PLOS are not related to the occurrence of postoperative complications.

Abstract
BACKGROUND Percutaneous endovascular treatment for arterial vascular diseases has revolutionized vascular care. While these procedures offer improved morbidity, mortality, and length of stay (LOS), their effect on postdischarge complications is unknown. The objectives of the study were to evaluate trends in LOS and postdischarge complications over time and to assess factors associated with postdischarge complications. METHODS Patients who underwent surgery for common vascular pathologies (abdominal aortic aneurysm, aortoiliac occlusive disease, lower extremity disease, and carotid stenosis) were identified from the American College of Surgeons National Surgical Quality Improvement Program procedure-targeted database (2014-2019). Outcomes included LOS, 30-day complications, and proportions of postdischarge complications. Predictors of postdischarge complications were assessed using a multivariable logistic regression. RESULTS Of 80,311 patients evaluated, median LOS did not change from 2014 to 2019 (2, interquartile range 1-5). Overall, 15.7% of patients experienced any 30-day complication, with 31.3% occurring after discharge. The proportion of postdischarge complications increased from 29.1% (2014) to 35.9% (2019), P < 0.001. With exception of carotid procedures, endovascular procedures had lower overall complication rates than open procedures; however, there was an increased proportion of postdischarge complications for endovascular procedures (all P < 0.001). Factors associated with an increased odds of postdischarge complications included female, Black or other race, dependent functional status, underweight or obesity, increased LOS, and procedural time, all P < 0.05. CONCLUSIONS Across 4 representative common vascular pathologies, endovascular treatments had a higher proportion of postdischarge complications compared to open procedures. Early identification and evaluation of postdischarge complications for endovascular patients may be warranted to avoid unplanned readmission.

Abstract
Background Patients who exceed their expected length of stay in the hospital come at a cost to stakeholders in the healthcare sector as bed spaces are limited for new patients, nosocomial infections increase and the outcome for many patients is hampered due to multimorbidity after hospitalization. Objectives This paper develops a technique for predicting Extended Length of Hospital Stay (ELOHS) at preadmission and their risk factors using hospital data. Methods A total of 91,468 records of patient’s hospital information from a private acute teaching hospital were used for developing a machine learning algorithm relaying on Recursive Feature Elimination with Cross-Validation and Extra Tree Classifier (RFECV-ETC). The study implemented Synthetic Minority Oversampling Technique (SMOTE) and tenfold cross-validation to determine the optimal features for predicting ELOHS while relying on multivariate Logistic Regression (LR) for computing the risk factors and the Relative Risk (RR) of ELOHS at a 95% confidence level. Results An estimated 11.54% of the patients have ELOHS, which increases with patient age as patients < 18 years, 18–40 years, 40–65 years and ≥ 65 years, respectively, have 2.57%, 4.33%, 8.1%, and 15.18% ELOHS rates. The RFECV-ETC algorithm predicted preadmission ELOHS to an accuracy of 89.3%. Age is a predominant risk factors of ELOHS with patients who are > 90 years—PAG (> 90) {RR: 1.85 (1.34–2.56), P: < 0.001} having 6.23% and 23.3%, respectively, higher likelihood of ELOHS than patient 80–90 years old—PAG (80–90) {RR: 1.74 (1.34–2.38), P: < 0.001} and those 70–80 years old—PAG (70–80) {RR: 1.5 (1.1–2.05), P: 0.011}. Those from admission category—ADC (US1) {RR: 3.64 (3.09–4.28, P: < 0.001} are 14.8% and 70.5%, respectively, more prone to ELOHS compared to ADC (UC1) {RR: 3.17 (2.82–3.55), P: < 0.001} and ADC (EMG) {RR: 2.11 (1.93–2.31), P: < 0.001}. Patients from SES (low) {RR: 1.45 (1.24–1.71), P: < 0.001)} are 13.3% and 45% more susceptible to those from SES (middle) and SES (high). Admission type (ADT) such as AS2, M2, NEWS, S2 and others {RR: 1.37–2.77 (1.25–6.19), P: < 0.001} also have a high likelihood of contributing to ELOHS while the distance to hospital (DTH) {RR: 0.64–0.75 (0.56–0.82), P: < 0.001}, Charlson Score (CCI) {RR: 0.31–0.68 (0.22–0.99), P: < 0.001–0.043} and some VMO specialties {RR: 0.08–0.69 (0.03–0.98), P: < 0.001–0.035} have limited influence on ELOHS. Conclusions Relying on the preadmission assessment of ELOHS helps identify those patients who are susceptible to exceeding their expected length of stay on admission, thus, making it possible to improve patients’ management and outcomes.

Abstract
Background: In recent years, the length of hospital stay (LOS) following endarterectomy has decreased significantly from 4 days to 1 day. LOS is influenced by several common complications and factors that can adversely affect the patient’s health and may vary from one healthcare facility to another. The aim of this work is to develop a forecasting model of the LOS value to investigate the main factors affecting LOS in order to save healthcare cost and improve management. Methods: We used different regression and machine learning models to predict the LOS value based on the clinical and organizational data of patients undergoing endarterectomy. Data were obtained from the discharge forms of the “San Giovanni di Dio e Ruggi d’Aragona” University Hospital (Salerno, Italy). R2 goodness of fit and the results in terms of accuracy, precision, recall and F1-score were used to compare the performance of various algorithms. Results: Before implementing the models, the preliminary correlation study showed that LOS was more dependent on the type of endarterectomy performed. Among the regression algorithms, the best was the multiple linear regression model with an R2 value of 0.854, while among the classification algorithms for LOS divided into classes, the best was decision tree, with an accuracy of 80%. The best performance was obtained in the third class, which identifies patients with prolonged LOS, with a precision of 95%. Among the independent variables, the most influential on LOS was type of endarterectomy, followed by diabetes and kidney disorders. Conclusion: The resulting forecast model demonstrates its effectiveness in predicting the value of LOS that could be used to improve the endarterectomy surgery planning.

The impact of case order and intraoperative staff changes on spine surgical efficiency. Spine J 2022; 22:1089-1099. [PMID: 35121151 DOI: 10.1016/j.spinee.2022.01.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 01/04/2022] [Accepted: 01/24/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Despite concerted efforts toward quality improvement in high-volume spine surgery, there remains concern that increases in case load may compromise the efficient and safe delivery of surgical care. There is a paucity of evidence to describe the effects of spine case order and operating room (OR) team structure on measures of intraoperative timing and OR efficiency. PURPOSE This study aims to determine if intraoperative staff changes and surgical case order independently predict extensions in intraoperative timing after spinal surgery for spondylotic diseases. STUDY DESIGN/ SETTING Retrospective cohort analysis PATIENT SAMPLE: All patients over age 18 who underwent primary or revision decompression and/or fusion for degenerative spinal diseases between 2017 to 2019 at a single academic institution were retrospectively identified. Exclusion criteria included absence of descriptive data and intraoperative timing parameters as well as surgery for traumatic injury, infection, and malignancy. OUTCOME MEASURES Intraoperative timing metrics including total theater time, wheels in to induction, induction start to cut, cut to close, and close to wheels out. Postoperative outcomes included length of hospital stay and 90-day hospital readmissions. METHODS Surgical case order and intraoperative changes in staff (circulator and surgical scrub nurse or technician) were determined. Patient demographics, surgical factors, intraoperative timing and postoperative outcomes were recorded. Extensions in each operative stage were determined as a ratio of the actual duration of the parameter divided by the predicted duration of the parameter. Univariate and multivariate analyses were performed to compare outcomes within case order and staff change groups. RESULTS A total of 1,108 patients met the inclusion criteria. First, second, and third start cases differed significantly in intraoperative extensions of total theater time, wheels in to induction, induction start to cut, cut to close, and close to wheels out. On regression, decreasing case order predicted extension in wheels in to induction time. Surgeries with intraoperative staff changes were associated with increases in total theater time, induction start to cut time, cut to close time, close to wheels out time, and length of hospital stay. Switch in primary circulator predicted extended theater time and cut to close time. Relief of primary circulator or scrub predicted extended total theater time, induction start to cut time, cut to close time, and close to wheels out time. CONCLUSIONS Intraoperative staff change in spine surgery independently predicted extended operative duration. However, higher case order was not significantly associated with procedural time.

Abstract
BACKGROUND Intensive care unit (ICU) admission after endovascular aortic aneurysm repair (EVAR) varies across medical centers. We evaluated the association of postoperative ICU use with perioperative and long-term outcomes after EVAR. STUDY DESIGN The Vascular Quality Initiative (2003-2019) was queried for index elective EVARs. Included centers were categorized by percentage of patients with EVARs postoperatively admitted to the ICU; routine ICU (rICU) centers as ≥80% ICU admissions and nonroutine ICU (nrICU) centers as ≤20% ICU admissions. Patients admitted preoperatively or with same day discharge were excluded. Perioperative outcomes and survival were compared between rICU and nrICU centers. RESULTS Of 45,310 EVARs in the database, 35,617 were performed at rICU or nrICU centers - 5,443 (15.3%) at 71 rICU centers and 30,174 (84.7%) at 200 nrICU centers. Overall, mean age was 73.4 years and 81.6% were male. Postoperative myocardial infarction, pulmonary complications, stroke, leg ischemia, and in-hospital mortality were similar between rICU and nrICU centers (all p > 0.05). Postoperative length of stay (LOS) was prolonged at rICU centers (mean) (2.2 ± 3.6 vs 2 ± 4.2 days, p < 0.001). One-year survival was similar between rICU and nrICU centers, respectively, (94.9% vs 95.4%, p = 0.085). When compared with nrICU centers, rICU centers had similar 1-year mortality risk (hazard ratio [HR] 1.15, 95% CI 0.99-1.34, p = 0.076), but were associated with longer postoperative LOS (means ratio 1.1, 95% CI 1.08-1.13, p < 0.001). CONCLUSIONS Routine ICU use after EVAR was associated with prolonged postoperative LOS, without improved perioperative/long-term morbidity or mortality. Updated care pathways to include postoperative admission to lower acuity care units may reduce costs without compromising care.

Hospital-Level Medicaid Prevalence Is Associated with Increased Length of Stay after Asymptomatic Carotid Endarterectomy and Stenting Despite no Increase in Major Complications. Ann Vasc Surg 2020; 71:65-73. [PMID: 32949743 DOI: 10.1016/j.avsg.2020.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 09/07/2020] [Accepted: 09/08/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Length of stay (LOS) after carotid endarterectomy (CEA) and carotid artery stenting (CAS) for asymptomatic disease is used as a quality measure and affects hospital operating margins. Patient-level Medicaid status has traditionally been associated with longer hospital LOS. Our goal was to assess the association between hospital-level Medicaid prevalence and postoperative LOS after CEA and CAS. METHODS The National Inpatient Sample was queried from 2006-2014 for CEA and CAS performed for asymptomatic carotid stenosis. Overall hospital-level Medicaid prevalence was divided into quartiles. The quartiles were further categorized into low Medicaid prevalence (LM) (lowest quartile), medium Medicaid prevalence (MM) (second and third quartiles), and high Medicaid prevalence (HM) (fourth quartile) cohorts. The primary outcome evaluated was postoperative LOS >1 day. The secondary outcomes included perioperative/in-hospital complications and mortality. RESULTS There were 984,283 patients with asymptomatic carotid stenosis who underwent CEA (88%) or CAS (12%). Mean postoperative LOS after CEA at hospitals with LM, MM, and HM prevalence was 1.4 ± 1.5, 2.1 ± 2.5, and 2.2 ± 2.8 days (P = 0.0001), respectively, and after CAS were 1.7 ± 2.6, 1.8 ± 2.1, and 2 ± 2.6 days (P < 0.0001), respectively. After CEA, relative to LM prevalence, MM (OR 1.62, 95% CI 1.17-2.24) and HM (OR 1.66, 95% CI 1.2-2.28) prevalence were associated with a higher likelihood of LOS > 1 day (P = 0.009). After CAS, relative to LM prevalence, HM prevalence was associated with a higher likelihood of LOS >1 day (OR 1.42, 95% CI 1.06-1.91) (P = 0.003). After CEA, neurologic (0.8% vs. 0.9% vs. 0.9%, P = 0.83) and cardiac complications (0.9% vs. 1.2% vs. 1.2%, P = 0.24) were similar among hospitals with LM, MM, and HM prevalence, respectively. After CAS, the prevalence of neurological (1.1% vs. 1% vs. 1.2%, P = 0.42) and cardiac complications (2% vs. 1.3% vs. 1.5%, P = 0.46) were also similar. After both CEA and CAS, mortality was similar among Medicaid prevalence cohorts. CONCLUSIONS Higher hospital-level Medicaid prevalence was associated with longer LOS after CEA and CAS for asymptomatic carotid stenosis. Value-based payment models should adjust for hospital-level Medicaid prevalence to appropriately reimburse providers and hospital with higher Medicaid prevalence as well as investigate care pathways and systems improvement to help reduce LOS.

Abstract
STUDY DESIGN Retrospective study of a surgical cohort from a single, large academic institution. OBJECTIVE The aim of this study was to investigate associations between surgical start time, length of stay, cost, perioperative outcomes, and readmission. SUMMARY OF BACKGROUND DATA One retrospective study with a smaller cohort investigated associations between surgical start time and outcomes in spine surgery and found that early start times were correlated with shorter length of stay. No examinations of perioperative outcomes or cost have been performed. METHODS All patients undergoing anterior cervical discectomy and fusion (ACDF) and posterior cervical decompression and fusion (PCDF) were queried from a single institution from January 1, 2008 to November 30, 2016. Patients undergoing surgery that started between 12:00 AM and 6:00 AM were excluded due to their likely emergent nature. Cases starting before and after 2:00 PM were compared on the basis of length of stay and cost as the primary outcomes using multivariable logistic regression. RESULT The patients undergoing ACDF and PCDF were both similar on the basis of comorbidity burden, preoperative diagnosis, and number of segments fused. The patients undergoing ACDF starting after 2 PM had longer LOS values (adjusted difference of 0.65 days; 95% confidence interval [CI]: 0.28-1.03; P = 0.0006) and higher costs of hospitalization (adjusted difference of $1177; 95% CI: $549-$1806; P = 0.0002). Patients undergoing PCDF starting after 2 PM also had longer LOS values (adjusted difference of 1.19 days; 95% CI: 0.46-1.91; P = 0.001) and higher costs of hospitalization (adjusted difference of $2305; 95% CI: $826-$3785; P = 0.002). CONCLUSION Later surgical start time is associated with longer LOS and higher cost. These findings should be further confirmed in the spine surgical literature to investigate surgical start time as a potential cost-saving measure. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVE The objective of this study was to evaluate factors affecting regional variation in length of stay (LOS) after elective, uncomplicated carotid endarterectomy (CEA). METHODS Data were obtained from the Vascular Quality Initiative database and included patients with complete data who received elective CEA without complications between 2012 and 2017 across 18 regions in North America and 294 centers. The main outcome measure was LOS >1 day after surgery (LOS >1 postoperative day [POD]). Using least absolute shrinkage and selection operator regression, multivariable modeling, and mixed-effects general linear modeling, we evaluated whether regional variations in LOS were independent of demographic, clinical, or center-related factors and to what extent these factors accounted for postoperative variation in LOS. RESULTS A total of 36,004 patients were included. Mean postprocedure LOS was 1.6 ± 6.6 days. Overall, 24% of patients had an LOS >1 POD. After adjustment for important demographic, clinical, and center-related factors, the region in which a patient was treated independently and significantly affected LOS after elective, uncomplicated CEA. Region and center of treatment accounted for 18% of LOS variation. Demographic, clinical, and surgical factors accounted for another 32% of variation in LOS. Of these factors, postoperative discharge to a facility other than home (odds ratio [OR], 6.3; confidence interval [CI], 5.2-7.6), use of intravenous (IV) vasoactive agents (OR, 3.2; CI, 3-3.4), intraoperative drain placement (OR, 1.4; CI, 1.3-1.55), and female sex (OR, 1.4; CI, 1.3-1.5) were associated with longer LOS. Factors associated with LOS ≤1 POD included preoperative aspirin (OR, 0.88; CI, 0.8-0.96) and statin use (OR, 0.9; CI, 0.83-0.98), high surgeon volume (highest quartile: OR, 0.68; CI, 0.5-0.87), and completion evaluation after CEA (eg, Doppler, ultrasound; OR, 0.87; CI, 0.8-0.95). We also found that use of IV vasoactive medications varied significantly across regions, independent of demographic and clinical factors. CONCLUSIONS Significant regional variation in LOS exists after elective, uncomplicated CEA even after controlling for a wide range of important factors, indicating that there remain unmeasured causes of longer LOS in some regions. Even so, modification of certain clinical practices may reduce overall LOS. Regional differences in use of IV vasoactive medications not driven by clinical factors warrant further analysis, given the strong association with longer LOS.

Abstract
Background Reducing the incidence of extended length of stay (ELOS) after carotid endarterectomy (CEA), defined as LOS > 1 day, is an important quality improvement focus of the Vascular Quality Initiative (VQI). Rural patients with geographic barriers pose a particular challenge for discharge and may have higher incidences of ELOS as a result. The purpose of this study was to examine the impact of patients’ home geographic location on ELOS after CEA. Methods The VQI national database for CEA comprised the sample for analyses ( N = 66,900). Rural-Urban Commuting Area (RUCA) codes, a validated system used to classify the nation’s census tracts according to rural and urban status, was applied to the VQI database and used to indicate patients’ home geographic location. LOS was categorized into two groups: LOS ≤ 1 day (66%) and LOS > 1 day (ELOS) (34%). Multivariable logistic regression was conducted to examine the effect of geographic location on ELOS after adjustment for age, gender, race, and comorbid conditions. Results A total of 66,900 patients were analyzed and the mean age of the sample was 70.5 ± 9.3 years (40% female). After adjustment for covariates, the urban group had increased risk for ELOS (OR = 1.20, p < 0.001). Other factors that significantly increased risk for ELOS were non-White race/Latinx/Hispanic ethnicity (OR = 1.44, p < 0.001) and nonelective status (OR = 3.31, p < 0.001). In addition, patients treated at centers with a greater percentage of urban patients had greater risk for ELOS (OR = 1.008, p < 0.001). Conclusions These analyses found that geographic location did impact LOS, but not in the hypothesized direction. Even with adjustment for comorbidities and other factors, patients from urban areas and centers with more urban patients were more likely to have ELOS after CEA. These findings suggest that other mechanisms, such as racial disparities, barriers in access to care, and disparities in support after discharge for urban patients may have a significant impact on LOS.

Abstract
OBJECTIVE Quality metrics were developed to improve outcomes after carotid artery revascularization; however, few studies have evaluated regional differences in perioperative outcomes. This study aimed to evaluate regional variation in mortality and perioperative outcomes after carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS We identified all patients who underwent CEA or CAS from 2009 to 2016 in the Vascular Quality Initiative. Patients were analyzed on the basis of their symptom status. We assessed variation in perioperative outcomes using χ2 analysis, Fisher exact test, and t-test, where appropriate. RESULTS A total of 78,467 carotid interventions were identified; 85% were CEAs, with 69% of those asymptomatic. Within CAS, 39% were asymptomatic. Perioperative stroke/death varied across regions within both CAS groups (asymptomatic, 0%-5.8% [P = .03]; symptomatic, 2.4%-8.1% [P = .1]), and several regions did not meet the American Heart Association (AHA) guidelines of 3% for asymptomatic patients and 6% for symptomatic patients, which persisted after risk adjustment. For CEA, the stroke/death rates fell within the standards set by the AHA guidelines in all regions for both the unadjusted and risk-adjusted models; however, there was significant regional variation in the cohorts (asymptomatic, 0.9%-3.1% [P < .01]; symptomatic, 1.3%-4.9% [P < .01]). Variation in 30-day mortality was significant in symptomatic patients (asymptomatic: CEA, 0%-1.3% [P = .2], CAS, 0%-2.4% [P = .2]; symptomatic: CEA, 0%-1.8% [P < .01], CAS, 0%-4.6% [P = .01]). Rates of in-hospital stroke, postoperative myocardial infarction, prolonged length of stay (>2 days), and use of intravenous blood pressure medications all varied significantly across the regions. After CEA, there was significant variation in the rates of cranial nerve injuries (asymptomatic, 0.9%-4.9% [P < .01]; symptomatic, 1.5%-7.7% [P < .01]), return to the operating room (asymptomatic, 0.9%-3.4% [P < .01]; symptomatic, 0.6%-3.4% [P = .02]), and discharge on antiplatelet and statin (asymptomatic, 75%-87% [P < .01]; symptomatic, 78%-91% [P < .01]). After CAS, significant variation was found in the rates of access site complications (asymptomatic, 2.3%-18.2% [P < .01]; symptomatic, 1.4%-16.9% [P < .01]) and discharge on dual antiplatelet therapy (asymptomatic, 79%-94% [P < .01]; symptomatic, 83%-93% [P < .01]). CONCLUSIONS Unwarranted regional variation exists in outcomes after carotid artery revascularization across the regions of the VQI. Significant variation was seen in a number of outcomes for which quality metrics currently exist, such as length of stay and discharge medications. In addition, after CAS, several regions failed to meet the AHA guidelines for stroke and death. Given these results, quality improvement projects should be targeted to improve adherence to current guidelines to promote best practices.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE To compare time to discharge for anterior cervical discectomy and fusions (ACDF) when performed as either a first case versus later surgical start times. SUMMARY OF BACKGROUND DATA ACDF is a commonly performed spinal procedure that typically has a short acute recovery period. With an increasing focus on reducing hospital costs and a shift toward outpatient surgical practices, early patient discharge has become a priority for hospitals and physicians alike. However, the impact of surgery start time on the ability for same-day discharge has not been explored in spine surgery. METHODS A surgical database of patients who underwent ACDF from 2013 to 2015 was reviewed. Patients were stratified into two cohorts: those whose surgery was the first of the day (early cohort), and those who underwent later surgeries. Baseline patient characteristics and perioperative variables were compared between cohorts using Student t test and χ test. Same-day discharge was tested for association with surgical start time using Poisson regression with robust error variance controlling for preoperative variables. RESULTS A total of 106 patients, divided into early and late cohorts of 60 and 46 patients, respectively, were included in the analysis. There were no significant differences in pre- or perioperative characteristics between cohorts (). Same-day discharge was achieved in 36.8% (n = 39) of all ACDF patients. The later cohort was significantly more likely to require an overnight stay compared with the early cohort (RR = 1.61 ± 0.30; P = 0.010).(Table is included in full-text article.)CONCLUSION.: Patients undergoing ACDF later in the day are at a higher risk for staying overnight than those who have the first surgery of the day. These results may influence operative scheduling, as performing ACDFs early in the day may result in a greater likelihood of same-day discharge, eliminating the increased resource utilization associated with an overnight hospital stay.

Abstract
BACKGROUND Carotid endarterectomy (CEA) is a commonly performed vascular operation. Yet, postoperative length of stay (LOS) varies greatly even within institutions. In this study, the morbidity and mortality, as well as financial impact of increased LOS were reviewed to establish modifiable factors associated with prolonged hospital stay. METHODS The Society for Vascular Surgery Vascular Quality Initiative database was used to identify all patients undergoing primary CEA at a single institution between June 1, 2011 and November 28, 2014. Preoperative patient characteristics, intraoperative details, postoperative factors, long-term outcomes, and cost data were reviewed using an Institutional Review Board-approved prospectively collected database. Multivariate analysis was used to determine statistical difference between patients with LOS ≤1 day and >1 day. RESULTS Complete 30-day variable and cost data were available for 219 patients with an average follow-up of 12 months. Seventy-nine (36%) patients had an LOS > 1 day. Variables determined to be statistically significant predictors of prolonged LOS included preoperative creatinine (P = 0.02) and severe congestive heart failure (P = 0.05) with self-pay status (P = 0.02) and preoperative beta-blocker therapy (P = 0.04) being protective. Shunt placement (P = 0.04), arterial re-exploration, and postoperative cardiac (P = 0.001) or neurological (P = 0.03) complications also resulted in prolonged hospitalization. Specific modifiable risk factors that contributed to increased LOS included operative start time after noon (P = 0.04), drain placement (P = 0.05), prolonged operative time (101 vs. 125 min, P = 0.01), return to the operating room (P = 0.01), and postoperative hypertension (P = 0.02) or hypotension (P = 0.04). Of note, there was no difference in LOS associated with technique (conventional versus eversion), patch use (P = 0.49), protamine administration (P = 0.60), electroencephalogram monitoring (P = 0.45), measurement of stump pressure (P = 0.63), Doppler (P = 0.36), or duplex (P = 0.92). Both hospital charges (P = 0.0001) and costs (P = 0.0001) were found to be significantly higher in patients with prolonged LOS, with no difference in physician charges (P = 0.10). Increased LOS after CEA was associated with an increase in 12-month mortality (P = 0.05). CONCLUSIONS Increased LOS was associated with increased hospital charges, costs, as well as significant morbidity and midterm mortality following CEA. Furthermore, this study highlights several modifiable risk factors leading to increased LOS. Identified factors associated with increase LOS can serve as targets for improving care in vascular surgery.

Abstract
Background Stroke is the number one cause of disability and third leading cause of death among adults in the United States. A major cause of stroke is carotid artery stenosis (CAS) caused by atherosclerotic plaques. Randomized trials have varying results regarding the equivalence and perioperative complication rates of stents versus carotid endarterectomy (CEA) in the management of CAS. Objectives We review the evidence for the current management of CAS and describe the current concepts and practice patterns of CEA. Methods A literature search was conducted using PubMed to identify relevant studies regarding CEA and stenting for the management of CAS. Results The introduction of CAS has led to a decrease in the percentage of CEA and an increase in the number of CAS procedures performed in the context of all revascularization procedures. However, the efficacy of stents in patients with symptomatic CAS remains unclear because of varying results among randomized trials, but the perioperative complication rates exceed those found after CEA. Conclusions Vascular surgeons are uniquely positioned to treat carotid artery disease through medical therapy, CEA, and stenting. Although data from randomized trials differ, it is important for surgeons to make clinical decisions based on the patient. We believe that CAS can be adopted with low complication rate in a selected subgroup of patients, but CEA should remain the standard of care. This current evidence should be incorporated into practice of the modern vascular surgeon.
