RESUMO
BACKGROUND AND AIMS: Predicting personalized risk for adverse events following percutaneous coronary intervention (PCI) remains critical in weighing treatment options, employing risk mitigation strategies, and enhancing shared decision-making. This study aimed to employ machine learning models using pre-procedural variables to accurately predict common post-PCI complications. METHODS: A group of 66 adults underwent a semiquantitative survey assessing a preferred list of outcomes and model display. The machine learning cohort included 107 793 patients undergoing PCI procedures performed at 48 hospitals in Michigan between 1 April 2018 and 31 December 2021 in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC2) registry separated into training and validation cohorts. External validation was conducted in the Cardiac Care Outcomes Assessment Program database of 56 583 procedures in 33 hospitals in Washington. RESULTS: Overall rate of in-hospital mortality was 1.85% (n = 1999), acute kidney injury 2.51% (n = 2519), new-onset dialysis 0.44% (n = 462), stroke 0.41% (n = 447), major bleeding 0.89% (n = 942), and transfusion 2.41% (n = 2592). The model demonstrated robust discrimination and calibration for mortality {area under the receiver-operating characteristic curve [AUC]: 0.930 [95% confidence interval (CI) 0.920-0.940]}, acute kidney injury [AUC: 0.893 (95% CI 0.883-0.903)], dialysis [AUC: 0.951 (95% CI 0.939-0.964)], stroke [AUC: 0.751 (95%CI 0.714-0.787)], transfusion [AUC: 0.917 (95% CI 0.907-0.925)], and major bleeding [AUC: 0.887 (95% CI 0.870-0.905)]. Similar discrimination was noted in the external validation population. Survey subjects preferred a comprehensive list of individually reported post-procedure outcomes. CONCLUSIONS: Using common pre-procedural risk factors, the BMC2 machine learning models accurately predict post-PCI outcomes. Utilizing patient feedback, the BMC2 models employ a patient-centred tool to clearly display risks to patients and providers (https://shiny.bmc2.org/pci-prediction/). Enhanced risk prediction prior to PCI could help inform treatment selection and shared decision-making discussions.

OBJECTIVE: The Society for Vascular Surgery (SVS) Wound, Ischemia, and foot Infection (WIfI) classification system aims to risk stratify patients with chronic limb-threatening ischemia (CLTI), predicting both amputation rates and the need for revascularization. However, real-world use of the system and whether it predicts outcomes accurately after open revascularization and peripheral interventions is unclear. Therefore, we sought to determine the adoption of the WIfI classification system within a contemporary statewide collaborative as well as the impact of patient factor, and WIfI risk assessment on short- and long-term outcomes. METHODS: Using data from a large statewide collaborative, we identified patients with CLTI undergoing open surgical revascularization or peripheral vascular intervention (PVI) between 2016 and 2022. The primary exposure was preoperative clinical WIfI stage. Patients were categorized according to the SVS Lower Extremity Threatened Limb Classification System into clinical WIfI stages 1, 2, 3, or 4. The primary outcomes were 30-day and 1-year amputation and mortality rates. Multivariable logistic regression was performed to estimate the association of WIfI stage on postrevascularization outcomes. RESULTS: In the cohort of 17,417 patients, 83.4% (n = 14,529) had WIfI stage documented. PVIs were performed on 57.6% of patients, and 42.4% underwent an open surgical revascularization. Of the patients, 49.5% were classified as stage 1, 19.3% stage 2, 12.8% stage 3, and 18.3% of patients met stage 4 criteria. Stage 3 and 4 patients had higher rates of diabetes, congestive heart failure, and renal failure, and were less likely to be current or former smokers. One-half of stage 3 patients underwent open surgical revascularization, whereas stage 1 patients were most likely to have received a PVI (64%). As WIfI stage increased from 1 to 4, 1-year mortality increased from 12% to 21% (P < .001), 30-day amputation rates increased from 5% to 38% (P < .001), and 1-year amputation rates increased from 15% to 55% (P < .001). Finally, patients who did not have WIfI scores classified had significantly higher 30-day and 1-year mortality rates, as well as higher 30-day and 1-year amputation rates. CONCLUSIONS: The SVS WIfI clinical stage is significantly associated with 1-year amputation rates in patients with CLTI after lower extremity revascularization. Because nearly 55% of stage 4 patients require a major amputation within 1 year of intervention, this finding study supports use of the WIfI classification system in clinical decision-making for patients with CLTI.
RESUMO
BACKGROUND: Ileostomies constitute 15% to 43% of readmissions after colorectal surgery, often due to dehydration and acute kidney injury. Prior institutional interventions decreased readmissions but not among patients who underwent new ileostomies. OBJECTIVE: To evaluate readmissions among patients who underwent new ileostomies after postoperative oral rehydration solution and standardized clinic visits. DESIGN: Retrospective analysis of prospective database. SETTINGS: Enhanced recovery colorectal surgery service. PATIENTS: Patients who underwent new ileostomy before and after intervention. INTERVENTIONS: Postoperative oral rehydration solution and postdischarge clinic visits with review of inputs/outputs, antimotility and appliance needs, and trained nurse reeducation 4 to 7 days after discharge, 30 days postoperatively, and every 1 to 2 weeks thereafter as needed. MAIN OUTCOME MEASURES: Readmission rate due to dehydration/acute kidney injury (primary), emergency department visits, and readmission rates overall and for specific diagnoses. Analysis used univariate and weighted techniques. RESULTS: A total of 312 patients (199 preintervention; 113 postintervention) were included, with a mean age of 59.0 years. Patients were predominantly White (94.9%) and evenly split between men and women. The most common diagnosis was diverticulitis (43.3%). The most common procedure was high anterior resection (38.8%), followed by low anterior resection (16.35%). Patient and procedure characteristics were well matched between groups. Multivariate analysis demonstrated that readmission rate due to dehydration/acute kidney injury significantly decreased between pre- and postintervention study groups (45.7% vs 16.5%, p = 0.039). Emergency department visits due to dehydration/acute kidney injury (12.0% vs 1.7%, p < 0.001) and readmissions from all causes (24.33% vs 10.6%, p = 0.005) also significantly decreased. Other complications were not significantly different between groups. Average stoma output 24 hours before (776 vs 625 mL, p = 0.005) and after (993 vs 890 mL, p = 0.025) discharge was significantly decreased in the postintervention group. LIMITATIONS: Retrospective single-center study. CONCLUSIONS: An oral rehydration solution and frequent standardized postdischarge visits led by trained nursing staff decreased readmissions and emergency department visits among patients who underwent new ileostomies after colorectal surgery.

LA REHIDRATACIN ORAL POSOPERATORIA Y EL SEGUIMIENTO REGLAMENTADO REDUCEN LOS REINGRESOS EN PACIENTES DE CIRUGA COLORRECTAL CON ILEOSTOMAS: ANTECEDENTES:Las ileostomías constituyen del 15 al 43% de los reingresos después de la cirugía colorrectal, a menudo debido a la deshidratación y la lesión renal aguda. Las intervenciones institucionales previas redujeron los reingresos, pero no entre los pacientes con nuevas ileostomías.OBJETIVO:Evaluar los reingresos entre pacientes con nuevas ileostomías después del uso de solución de rehidratación oral postoperatoria y visitas clínicas estandarizadas.DISEÑO:Análisis retrospectivo de base de datos prospectiva.AJUSTES:Servicio de cirugía colorrectal de recuperación mejorada.PACIENTES:Pacientes con ileostomía nueva antes y después de la intervención.INTERVENCIÓN(ES):Solución de rehidratación oral posoperatoria y visitas clínicas posteriores al alta con revisión de entradas/salidas, antimotilidad y necesidades de aparatos, y reeducación de enfermeras capacitadas 4-7 días después del alta, 30 días después de la operación y cada 1-2 semanas después, según sea necesario.PRINCIPALES MEDIDAS DE RESULTADO:Tasa de readmisión debido a deshidratación/lesión renal aguda (primaria), tasa de urgencias y de readmisión en general y para diagnósticos específicos. El análisis utilizó técnicas univariadas y ponderadas.RESULTADOS:Se incluyeron un total de 312 pacientes (199 preintervención; 113 postintervención), con una edad media de 59,0 años. Los pacientes eran predominantemente blancos (94,9%) y se dividieron equitativamente entre hombres y mujeres. El diagnóstico más frecuente fue diverticulitis (43,3%). El procedimiento más común fue la resección anterior alta (38,8 %) seguida de la resección anterior baja (16,35 %). Las características del paciente y del procedimiento coincidieron bien entre los grupos. El análisis multivariante demostró que la tasa de reingreso debido a deshidratación/lesión renal aguda disminuyó significativamente entre los grupos de estudio antes y después de la intervención (45,7 % frente a 16,5 %, p = 0,039). Las visitas a urgencias por deshidratación/insuficiencia renal aguda (12,0 % frente a 1,7 %, p < 0,001) y los reingresos por todas las causas (24,33 % frente a 10,6 %, p = 0,005) también disminuyeron significativamente. Otras complicaciones no fueron significativamente diferentes entre los grupos. El gasto medio del estoma 24 horas antes (776 ml frente a 625 ml, p = 0,005) y después (993 ml frente a 890 ml, p = 0,025) del alta disminuyó significativamente en el grupo posterior a la intervención.LIMITACIONES:Estudio retrospectivo de centro único.CONCLUSIONES:Una solución de rehidratación oral y frecuentes visitas estandarizadas posteriores al alta dirigidas por personal de enfermería capacitado redujeron los reingresos y las visitas al servicio de urgencias entre los pacientes con nuevas ileostomías después de la cirugía colorrectal.

OBJECTIVE: To evaluate the potential pathway, through which race and socioeconomic status, as measured by the social deprivation index (SDI), affect outcomes after lower extremity bypass chronic limb-threatening ischemia (CLTI), a marker for delayed presentation. BACKGROUND: Racial and socioeconomic disparities persist in outcomes after lower extremity bypass; however, limited studies have evaluated the role of disease severity as a mediator to potentially explain these outcomes using clinical registry data. METHODS: We captured patients who underwent lower extremity bypass using a statewide quality registry from 2015 to 2021. We used mediation analysis to assess the direct effects of race and high values of SDI (fifth quintile) on our outcome measures: 30-day major adverse cardiac event defined by new myocardial infarction, transient ischemic attack/stroke, or death, and 30-day and 1-year surgical site infection (SSI), amputation and bypass graft occlusion. RESULTS: A total of 7077 patients underwent a lower extremity bypass procedure. Black patients had a higher prevalence of CLTI (80.63% vs 66.37%, P < 0.001). In mediation analysis, there were significant indirect effects where Black patients were more likely to present with CLTI, and thus had increased odds of 30-day amputation [odds ratio (OR): 1.11, 95% CI: 1.068-1.153], 1-year amputation (OR: 1.083, 95% CI: 1.045-1.123) and SSI (OR: 1.052, 95% CI: 1.016-1.089). There were significant indirect effects where patients in the fifth quintile for SDI were more likely to present with CLTI and thus had increased odds of 30-day amputation (OR: 1.065, 95% CI: 1.034-1.098) and SSI (OR: 1.026, 95% CI: 1.006-1.046), and 1-year amputation (OR: 1.068, 95% CI: 1.036-1.101) and SSI (OR: 1.026, 95% CI: 1.006-1.046). CONCLUSIONS: Black patients and socioeconomically disadvantaged patients tended to present with a more advanced disease, CLTI, which in mediation analysis was associated with increased odds of amputation and other complications after lower extremity bypass compared with White patients and those that were not socioeconomically disadvantaged.

OBJECTIVE: The surgical treatment of claudication can be associated with significant morbidity and costs. There are growing concerns that some patients proceed to interventions without first attempting evidence-based nonoperative management. We used a direct, cross-site, blinded expert review to evaluate the appropriateness of the surgical treatment of claudication. METHODS: We enlisted practicing vascular surgeons to perform retrospective clinical assessments of lower extremity bypass procedures in a statewide clinical registry. Cases were limited to elective, open, infrainguinal bypasses performed for claudication using prosthetic grafts. Reviewing surgeons were randomly assigned 10 cases from a sample of 139 anonymized bypass operations and instructed to evaluate procedural appropriateness based on their expert opinion and evidence-based guidelines for preoperative treatment, namely, antiplatelet, statin, cilostazol, exercise, and smoking cessation therapy as documented in the medical record. Ninety-day episode payments were estimated from a distinct but similar cohort of patients undergoing lower extremity bypass for claudication. RESULTS: Of 325 total reviews, surgeons stated they would not have recommended bypass in 134 reviews (41%) and deemed bypass inappropriate in 122 reviews (38%). The most common reason for inappropriateness was lack of preoperative medical and lifestyle therapy, which was present in 63% of reviews where bypass was deemed appropriate and 39% of reviews where bypass was deemed inappropriate (P < .001). Surgeons stated they would have recommended additional preoperative therapy in 65% of reviews where bypass was deemed inappropriate and 35% of reviews where bypass was deemed appropriate (P < .001). The mean total episode payments in a similar cohort of 1458 patients undergoing elective open lower extremity bypass for claudication were $31,301 ± $21,219. Extrapolating to the 325 reviews, the 134 reviews in which surgeons would not have recommended bypass were associated with potentially avoidable estimated total payments of $4,194,334, and the 122 reviews in which bypass was deemed inappropriate were associated with potentially avoidable estimated total payments of $3,818,722. CONCLUSIONS: In this cross-site expert peer review study, 40% of lower extremity bypasses were deemed premature and, therefore, potentially avoidable, primarily owing to a lack of medical and lifestyle management before surgery. Reviews deemed inappropriate were associated with approximately $4 million in potentially avoidable costs. This approach could inform performance feedback among surgeons to help align clinical practice with evidence-based recommendations for the treatment of claudication.

BACKGROUND: A Michigan Surgical Quality Collaborative Colorectal Cancer Project initiative sought to increase adoption of surgeon total mesorectal excision (TME) grading through standardized education and synoptic operative reporting. Our study aim was to assess initiative impact and level of agreement between surgeon and pathologist-determined TME grades. METHODS: This is a retrospective comparison of surgeon and pathologist TME grades before and after initiative implementation using a prospectively maintained enhanced recovery colorectal surgery database. RESULTS: There were 112 TMEs before, and 53 TMEs following initiative implementation. There was a significant increase in surgeon TME-grade reporting in the postinitiative period (25.0% pre- vs. 81.1% post-, p < 0.001). Pathologist TME-grade reporting was high in both time periods and there was no significant change (91.1% pre- vs. 88.7% post-, p = 0.84). Surgeon and pathologist agreement was 59.3% in the preinitiative period (Κ "minimal" 0.356) and 65.0% in the postinitiative period (Κ "moderate" = 0.605, p = 0.827). There was no significant association between clinical T-stage and surgeon or pathologist TME grade. CONCLUSION: Surgeon TME grading improves with education and synoptic operative reporting. There is only moderate agreement between surgeon and pathologist, a finding that requires further study. Organized regional initiatives are effective at implementing rectal cancer management quality improvement.

BACKGROUND: Alvimopan is a µ-opioid receptor antagonist associated with shorter time to gastrointestinal recovery in patients having open colorectal surgery. Data demonstrating the benefit of perioperative alvimopan for the minimally invasive surgical approach are inconsistent. The aim of this study is to determine colorectal surgery groups that benefit from perioperative alvimopan. METHODS: This is a retrospective cohort analysis of colorectal surgery patients who had, and patients who did not have, perioperative alvimopan in the Michigan Surgical Quality Collaborative regional risk-adjusted database from 2018 through 2021. Main outcome measures were postoperative length of hospital stay, time to return of bowel function, and postoperative ileus. RESULTS: There were 10,010 patients (30.3% open, 40.5% laparoscopic, 12.7% hand-assist laparoscopic, 43.5% robotic) who met inclusion criteria-4919 received alvimopan in the perioperative period and 5091 did not. When compared to those not receiving alvimopan, unadjusted outcomes showed that the alvimopan group had significantly shorter postoperative length of stay (4.75 days vs 5.5 days, p < 0.001), shorter time to return of bowel function (1.61 days vs 2.01 days, p < 0.001) and less postoperative ileus (5.45% vs 7.94%, p < 0.001). After adjustment, regression models confirmed that alvimopan was associated with an 9.6% reduction in hospital length of stay (p < 0.001), a 14.9% shorter time to return of bowel function (p < 0.001), and a 42.1% reduction in postoperative ileus (p < 0.001). Subgroup analysis showed significant benefit of alvimopan for all three outcomes in patients having the minimally invasive approach. CONCLUSIONS: Alvimopan is associated with shorter hospital length of stay, shorter time to return of bowel function, and decreased postoperative ileus when administered to patients undergoing colorectal surgery. Benefit is not limited to the open approach and includes minimally invasive laparoscopic and robotic colorectal procedures.

BACKGROUND: Cannabis is one of the most commonly used substances in the United States, with national use on the rise. However, there is a paucity of data regarding the effects of cannabis and surgical outcomes. The aim of this study was to assess the association of cannabis use on postoperative outcomes after lower extremity bypass. METHODS: We queried a large statewide registry from 2014 to 2021 to assess patients who underwent lower extremity bypass procedures. Data were gathered regarding cannabis use and the association with postoperative outcomes at 30 days and 1 year. RESULTS: A total of 11,013 patients were identified. Ninety-one percent of patients (10,024) reported no cannabis use, whereas 9.0% (989) reported cannabis use in the past month. Compared with noncannabis users, patients using cannabis had higher opioid use at discharge (odds ratio [OR]: 1.56, 95% confidence interval [CI]: 1.28-1.90), decreased bypass patency at 30 days (OR: 0.52, 95% CI: 0.36-0.78) and 1 year (OR: 0.64, 95% CI 0.47-0.86), and an increased amputation rate at 1 year (OR: 1.25, 95% CI: 1.02-1.52) after lower extremity bypass. CONCLUSIONS: This study shows that cannabis use in vascular surgical patients was associated with decreased graft patency, increased amputation, and increased opioid use after lower extremity bypass procedures. Although future studies are needed, the present study provides novel data that can be used to counsel patients undergoing vascular surgery.

BACKGROUND: Contrast-associated acute kidney injury (CA-AKI) after endovascular abdominal aortic aneurysm repair (EVAR) is associated with mortality and morbidity. Risk stratification remains a vital component of preoperative evaluation. We sought to generate and validate a preprocedure CA-AKI risk stratification tool for elective EVAR patients. METHODS: We queried the Blue Cross Blue Shield of Michigan Cardiovascular Consortium database for elective EVAR patients and excluded those on dialysis, with a history of renal transplant, death during procedure, and without creatinine measures. Association with CA-AKI (rise in creatinine > 0.5 mg/dL) was tested using mixed-effects logistic regression. Variables associated with CA-AKI were used to generate a predictive model via a single classification tree. The variables selected by the classification tree were then validated by fitting a mixed-effects logistic regression model into the Vascular Quality Initiative dataset. RESULTS: Our derivation cohort included 7,043 patients, 3.5% of whom developed CA-AKI. After multivariate analysis, age (odds ratio [OR] 1.021, 95% confidence interval [CI] 1.004-1.040), female sex (OR 1.393, CI 1.012-1.916), glomerular filtration rate (GFR) < 30 mL/min (OR 5.068, CI 3.255-7.891), current smoking (OR 1.942, CI 1.067-3.535), chronic obstructive pulmonary disease (OR 1.402, CI 1.066-1.843), maximum abdominal aortic aneurysm (AAA) diameter (OR 1.018, CI 1.006-1.029), and presence of iliac artery aneurysm (OR 1.352, CI 1.007-1.816) were associated with increased odds of CA-AKI. Our risk prediction calculator demonstrated that patients with a GFR < 30 mL/min, females, and patients with a maximum AAA diameter of > 6.9 cm are at a higher risk of CA-AKI after EVAR. Using the Vascular Quality Initiative dataset (N = 62,986), we found that GFR < 30 mL/min (OR 4.668, CI 4.007-5.85), female sex (OR 1.352, CI 1.213-1.507), and maximum AAA diameter > 6.9 cm (OR 1.824, CI 1.212-1.506) were associated with an increased risk of CA-AKI after EVAR. CONCLUSIONS: Herein, we present a simple and novel risk assessment tool that can be used preoperatively to identify patients at risk of CA-AKI after EVAR. Patients with a GFR < 30 mL/min, maximum AAA diameter > 6.9 cm, and females who are undergoing EVAR may be at risk for CA-AKI after EVAR. Prospective studies are needed to determine the efficacy of our model.

BACKGROUND: Over 150,000 carotid endarterectomies (CEA) are performed annually worldwide, accounting for $900 million in the United States alone. How cost/spending and quality are related is not well understood but remain essential components in maximizing value. We sought to identify determinants of variability in hospital 90-day episode value for CEA. METHODS: Medicare and private-payer admissions for CEA from January 2, 2014 to August 28, 2020 were linked to retrospective clinical registry data for hospitals in Michigan performing vascular surgery. Hospital-specific, risk-adjusted, 30-day composite complications (defined as reoperation, new neurologic deficit, myocardial infarction, additional procedure including CEA or carotid artery stenting, readmission, or mortality) and 30-day risk-adjusted, price-standardized total episode payments were used to categorize hospitals into low or high value by defining the intersection between complications and spending. RESULTS: A total of 6,595 patients across 39 hospitals were identified across both datasets. Patients at low-value hospitals had a higher rate of 30-day composite complications (17.9% vs. 10.1%, P < 0.001) driven by a significantly higher rate of reoperation (3.0% vs. 1.4%, P = 0.016), readmission (10.7% vs. 6.2%, P = 0.012), new neurologic deficit (4.6% vs. 2.3%, P = 0.017), and mortality (1.6% vs. 0.6%, P < 0.049). Mean total episode payments were $19,635 at low-value hospitals compared to $15,709 at high-value hospitals driven by index hospitalization ($10,800 vs. $9,587, P = 0.002), professional ($3,421 vs. $2,827, P < 0.001), readmission ($3,011 vs. $1,826, P < 0.001), and post-acute care payments ($2,335 vs. $1,486, P < 0.001). Findings were similar when only including patients who did not suffer a complication. CONCLUSIONS: There is tremendous variation in both quality and payments across hospitals included for CEA. Importantly, costs were higher at low-value hospitals independent of postoperative complication. There appears to be little to no relationship between total episode spending and surgical quality, suggesting that improvements in value may be possible by decreasing total episode cost without affecting surgical outcomes.

BACKGROUND: Adequate sedation to complement regional techniques in carotid endarterectomy (CEA) can be challenging. Dexmedetomidine has both analgesic and amnesic properties and is reported to be a safe and acceptable alternative to conventional general endotracheal anesthesia (GETA). Outcomes observing dexmedetomidine in conjunction with regional anesthesia in CEA are not well described or known. OBJECTIVE: Compare the immediate (during hospitalization) and short-term (within 30 days of hospitalization) postoperative outcomes in patients who underwent CEA using GETA versus local regional anesthesia (LRA) alone versus dexmedetomidine with LRA at a single institution to determine whether dexmedetomidine is a safe adjunct and if there are anesthesia advantages over LRA alone. METHODS: A retrospective cohort study from January 2015 to December 2019 at Saint Joseph Mercy Ann Arbor. Patients were stratified into three groups based on anesthesia type: GETA, LRA, and dexmedetomidine (D) + LRA. Primary outcomes included stroke, myocardial infarction (MI), and death. Patient demographics were characterized and adjusted using propensity score weighting. RESULTS: Three hundred seventy nine patients met inclusion criteria; 182 patients in the GETA group, 66 in the D + LRA, and 131 in LRA. There were no significant differences across anesthesia groups in primary outcomes of stroke, MI, and death during the admission. The GETA group had significantly longer length of stay (LOS) compared to the D + LRA group (LOS = 1.51 days versus 0.85 days; P = 0.011) and the LRA group (LOS = 1.08 days; P = 0.003). However, there was no significant difference in hospital LOS between the D + LRA group and LRA only groups (P = 0.952). There was no significant difference between stroke (LRA 0.87%, GETA 0.85%, and LRA + Dex 3.52%), MI (LRA 0%, GETA 0.49%, LRA + Dex 0%), or death (LRA 5.24%, GETA 1.16%, LRA + Dex 0%), within 30 days between all three of the anesthesia groups. There was no significant difference in postoperative pain scores when comparing the GETA group (mean 1.3, standard deviation [SD] 2.5) to LRA (mean 1.2, SD 2.1) and between LRA and D + LRA (mean 0.9, SD 2.1). Procedure time (time of skin incision to closure) and total room time were comparable among all three anesthesia groups (LRA 2.2 hr, SD 2.2; GETA 2.1 hr, SD 0.5; LRA + Dex 2.1 hr, SD 0.5). CONCLUSIONS: The use of dexmedetomidine in addition to LRA is a safe and acceptable alternative to conventional GETA or LRA alone in CEA with shorter length of hospital stay when compared with GETA, improved patient tolerance based on physician observation, and similar rates of immediate and short-term complications and postoperative pain scores.

OBJECTIVE: Tobacco use is common among vascular surgery patients and negatively impacts outcomes and longevity. In the second quarter of 2018, a statewide vascular quality collaborative launched an initiative across its 35 participating hospitals to promote smoking cessation at the time of surgery. This intervention was based on the Vascular Physician Offer and Report (VAPOR) trial and consisted of 3 components: brief physician-delivered advice, referral to telephone-based counseling, and nicotine replacement therapy. The goal of this study is to evaluate the results of this intervention. METHODS: We performed a retrospective analysis of patients undergoing vascular surgery between 2018 and 2020. Procedures included open abdominal aortic aneurysm repair, endovascular aneurysm repair, open vascular bypass, open thrombectomy, carotid endarterectomy, and carotid stenting. The primary explanatory variables were receipt of tobacco cessation interventions as documented in the medical record. The primary outcome was tobacco cessation, captured during 30-day and 1-year chart review and/or patient follow-up. A multivariable logistic regression model was calculated to estimate the association of covariates with smoking cessation while adjusting for patient and clinical characteristics. RESULTS: A total of 13,890 patients underwent surgery during the study period. The mean age was 69.4 ± 10 years; 4687 patients (34%) were female, and 5158 patients (37%) were current smokers. At least one smoking cessation component was delivered to 2245 patients (44% of smokers). The quit rate was 35% among 4671 patients with 30-day follow-up and 43% among 2936 patients with 1-year follow up. On multivariable regression, at 30 days, receiving two intervention components was associated with 1.29 (95% confidence interval [CI], 1.07-1.55) higher odds of quitting. At both time points, smoking cessation was also associated with undergoing an emergent procedure (30-day odds ratio [OR], 1.52; 95% CI, 1.16-1.99; 1-year OR, 1.41; 95% CI, 1.01-1.97) and undergoing open abdominal aortic aneurysm repair (30-day OR, 1.71; 95% CI, 1.20-2.43; 1-year OR, 1.75; 95% CI, 1.11-2.78). CONCLUSIONS: In a cohort of vascular surgical patients where tobacco use was common, nearly one-half of patients quit smoking 1 year after surgery. Receiving two smoking cessation intervention components was associated with quitting at 30 days. Overall, these results demonstrate encouraging quit rates and identify an opportunity for longer-term intervention to maintain even greater 1-year tobacco cessation.

OBJECTIVE: Opioid use is common among patients with peripheral arterial disease (PAD), given that pain is a defining symptom. Unfortunately, long-term opioid use places patients at dramatically increased risk of overdose and death. Although surgical revascularization is extremely effective in alleviating ischemic pain related to PAD, it is unclear whether this practice results in the discontinuation of opioids after surgery. Therefore, we conducted the following study to investigate trends in opioid use before and after surgical bypass in patients with PAD, as well as the risk factors for continued opioid use after surgery. METHODS: We conducted a retrospective analysis of patients undergoing open lower extremity bypass for claudication or rest pain between June 1, 2017, and March 31, 2021. Patients were grouped according to whether they reported preoperative opioid use at the time of surgery. The primary outcome was continued opioid use at 30-day follow-up after discharge. A multivariable logistic regression was conducted to estimate the association of continued opioid use with patient characteristics, preoperative opioid use, and receiving a postoperative opioid prescription. RESULTS: Among 3873 patients undergoing surgery, the mean age was 65.7 (10.2) years and 2650 (68.4%) patients were male. There were 913 patients (23.6%) who used opioids preoperatively and hydrocodone was the most common preoperative opioid (583 [63.9%]). At discharge, 2506 patients (64.7%) received a postoperative opioid prescription. Postoperative opioid prescriptions were significantly more common for preoperative opioid users than opioid-naïve patients (813 [89.0%] vs 1693 [57.2%]; P < .001) and were significantly larger in size (24.3 [21.1] pills vs 19.9 [10.5] pills; P < .001). On 30-day follow-up, 522 preoperative opioid users (61.3%) and 616 opioid-naïve patients (28.4%) reported that they were still using opioids (P < .001). Continued opioid use at follow-up was associated with preoperative opioid use (adjusted odds ratio, 3.23; 95% confidence interval, 2.70-3.89) and receiving a postoperative opioid prescription (adjusted odds ratio, 10.83; 95% confidence interval, 7.96-15.06). CONCLUSIONS: Most patients with PAD who use opioids preoperatively do not discontinue opioids after lower extremity bypass. Moreover, a significant proportion of previously opioid-naïve patients are still using opioids 1 month after surgery. In both cases, postoperative opioid prescriptions had the strongest association with continued opioid use. These findings underscore the need for improved prescribing practice and increased attentiveness to discontinuation of unnecessary medications after surgery.

BACKGROUND: Quality improvement national registries provide structured, clinically relevant outcome and process-of-care data to practitioners-with regional meetings to disseminate best practices. However, whether a quality improvement collaborative affects processes of care is less clear. We examined the effects of a statewide hospital collaborative on the adherence rates to best practice guidelines in vascular surgery. METHODS: A large statewide retrospective quality improvement database was reviewed for 2013 to 2019. Hospitals participating in the quality improvement collaborative were required to submit adherence and outcomes data and meet semiannually. They received an incentive through a pay for participation model. The aggregate adherence rates among all hospitals were calculated and compared. RESULTS: A total of 39 hospitals participated in the collaborative, with attendance of surgeon champions at face-to-face meetings of >85%. Statewide, the hospital systems improved every year of participation in the collaborative across most "best practice" domains, including adherence to preoperative skin preparation recommendations (odds ratio [OR], 1.83; 95% confidence interval [CI], 1.76-1.79; P < .001), intraoperative antibiotic redosing (OR, 1.09; 95% CI, 1.02-1.17; P = .018), statin use at discharge for appropriate patients (OR, 1.18; 95% CI, 1.16-1.2; P < .001), and reducing transfusions for asymptomatic patients with hemoglobin >8 mg/dL (OR, 0.66; 95% CI, 0.66-0.66; P < .001). The use of antiplatelet therapy at discharge remained high and did not change significantly during the study period. Teaching hospital and urban or rural status did not affect adherence. The adherence rates exceeded the professional society mean rates for guideline adherence. CONCLUSIONS: The use of a statewide hospital collaborative with incentivized semiannual meetings resulted in significant improvements in adherence to "best practice" guidelines across a large, heterogeneous group of hospitals.

OBJECTIVE: First-line treatment of peripheral artery disease (PAD) involves medical therapy and lifestyle modification. Multiple professional organizations such as the Society for Vascular Surgery and the American Heart Association/American College of Cardiology make Class I recommendations for medical management including antiplatelet, statin, antihypertensive, and cilostazol medications, as well as lifestyle therapy including exercise and smoking cessation. Although evidence supports up-front medical and lifestyle management prior to surgical intervention, it is unclear how well this occurs in contemporary clinical practice. It is also unclear whether variability in first-line treatment prior to revascularization is associated with postoperative outcomes. This study examined the proportion of patients with claudication actively receiving evidence-based therapy prior to surgery in a statewide surgical registry. METHODS: We conducted a retrospective cohort study of adult patients undergoing elective open lower extremity bypass for claudication from 2012 to 2021 within a statewide surgical quality registry. The primary exposure was optimal medical therapy, defined as an antiplatelet agent, a statin, and an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker (if the patient had hypertension) on the patient's home medication list on admission for surgery, all of which are Class I recommendations. Despite also being Class I recommendations, cilostazol was not included in the primary exposure due to its highly selective use and our inability to capture intolerance and/or contraindications that are common, and lifestyle therapies were not included as they were only recorded at the time of discharge rather than preoperatively. The primary outcomes were mortality, hospital readmission, amputation, wound complication, myocardial infarction (MI), non-patent bypass, and non-independent ambulatory status at 30 days and 1 year after surgery. Multivariable logistic regression was performed to estimate the association of receiving optimal vs non-optimal medical therapy. RESULTS: A total of 3829 patients with claudication underwent bypass surgery during the study period, with a mean age of 64.8 years (standard deviation, 9.8 years); 2690 (70.3%) were males, and 1873 (48.9%) were current smokers. Of the patients, 1822 (47.6%) were on optimal medical therapy prior to surgery. Additionally, at discharge, 66.5% of smokers received referral to smoking cessation therapy, and 54.1% of patients received referral to exercise therapy. In a multivariable logistic regression, compared with patients not on optimal medical therapy, patients on optimal medical therapy prior to surgery had lower 30-day odds of mortality (adjusted odds ratio [aOR], 0.45; 95% confidence interval [CI], 0.26-0.78) and MI (aOR, 0.46; 95% CI, 0.28-0.76), lower 1-year odds of mortality (aOR, 0.57; 95% CI, 0.39-0.82), MI (aOR, 0.48; 95% CI, 0.32-0.74), and lower readmission (aOR, 0.79; 95% CI, 0.64-0.96). CONCLUSIONS: Although medical and lifestyle management is recommended as first-line treatment for patients with PAD, only one-half of patients were on optimal medical therapy prior to surgery. Patients receiving optimal therapy had a lower risk of postoperative mortality, MI, and readmission. This suggests that not only are there significant opportunities to improve clinical utilization of evidence-based treatment of PAD, but that doing so can benefit patients postoperatively.

OBJECTIVE: The delays in elective surgery caused by the coronavirus disease 2019 (COVID-19) pandemic have resulted in a substantial backlog of cases. In the present study, we sought to determine the estimated time to recovery for vascular surgery procedures delayed by the COVID-19 pandemic in a regional health system. METHODS: Using data from a 35-hospital regional vascular surgical collaborative consisting of all hospitals performing vascular surgery in the state of Michigan, we estimated the number of delayed surgical cases for adults undergoing carotid endarterectomy, carotid stenting, endovascular and open abdominal aortic aneurysm repair, and lower extremity bypass. We used seasonal autoregressive integrated moving average models to predict the surgical volume in the absence of the COVID-19 pandemic and historical data to predict the elective surgical recovery time. RESULTS: The median statewide monthly vascular surgical volume for the study period was 439 procedures, with a maximum statewide monthly case volume of 519 procedures. For the month of April 2020, the elective vascular surgery procedural volume decreased by â¼90%. Significant variability was seen in the estimated hospital capacity and estimated number of backlogged cases, with the recovery of elective cases estimated to require â¼8 months. If hospitals across the collaborative were to share the burden of backlogged cases, the recovery could be shortened to â¼3 months. CONCLUSIONS: In the present study of vascular surgical volume in a regional health collaborative, elective surgical procedures decreased by 90%, resulting in a backlog of >700 cases. The recovery time if all hospitals in the collaborative were to share the burden of backlogged cases would be reduced from 8 months to 3 months, underscoring the necessity of regional and statewide policies to minimize patient harm by delays in recovery for elective surgery.

BACKGROUND: Complex abdominal aortic aneurysms (AAAs) have traditionally been treated with an open surgical repair (OSR). During the past decade, fenestrated endovascular aneurysm repair (FEVAR) has emerged as a viable option. Hospital procedural volume to outcome relationship for OSR of complex AAAs has been well established, but the impact of procedural volume on FEVAR outcomes remains undefined. This study investigated the outcomes of OSR and FEVAR for the treatment of complex AAAs and examined the hospital volume-outcome relationship for these procedures. METHODS: A retrospective review of a statewide vascular surgery registry was queried for all patients between 2012 and 2018 who underwent elective repair of a juxtarenal/pararenal AAA with FEVAR or OSR. The primary outcomes were 30-day mortality, myocardial infarction, and new dialysis. Secondary end points included postoperative pneumonia, renal dysfunction (creatine concentration increase of >2 mg/dL from preoperative baseline), major bleeding, early procedural complications, length of stay, and need for reintervention. To evaluate procedural volume-outcomes relationship, hospitals were stratified into low- and high-volume aortic centers based on a FEVAR annual procedural volume. To account for baseline differences, we calculated propensity scores and employed inverse probability of treatment weighting in comparing outcomes between treatment groups. RESULTS: A total of 589 patients underwent FEVAR (n = 186) or OSR (n = 403) for a complex AAA. After adjustment, OSR was associated with higher rates of 30-day mortality (10.7% vs 2.9%; P < .001) and need for dialysis (11.3% vs 1.8; P < .001). Postoperative pneumonia (6.8% vs 0.3%; P < .001) and need for transfusion (39.4% vs 10.4%; P < .001) were also significantly higher in the OSR cohort. The median length of stay for OSR and FEVAR was 9 days and 3 days, respectively. For those who underwent FEVAR, endoleaks were present in 12.1% of patients at 30 days and 6.1% of patients at 1 year, with the majority being type II. With a median follow-up period of 331 days (229-378 days), 1% of FEVAR patients required a secondary procedure, and there were no FEVAR conversions to an open aortic repair. Hospitals were divided into low- and high-volume aortic centers based on their annual FEVAR volume of complex AAAs. After adjustment, hospital FEVAR procedural volume was not associated with 30-day mortality or myocardial infarction. CONCLUSIONS: FEVAR was associated with lower perioperative morbidity and mortality compared with OSR for the management of complex AAAs. Procedural FEVAR volume outcome analysis suggests limited differences in 30-day morbidity, although long-term durability warrants further research.

OBJECTIVE: Widespread adoption of direct oral anticoagulants (DOACs) for atrial fibrillation and venous thromboembolism treatment has resulted in peripheral bypass patients receiving therapeutic anticoagulation with DOACs postoperatively. This study was undertaken to evaluate patient outcomes after open peripheral bypass based on anticoagulation treatment. METHODS: Postoperative treatment and outcomes of patients undergoing peripheral bypass operations between January 2012 and December 2017 from a statewide multicenter quality improvement registry were examined. Surgeons participating in the registry were surveyed on practice patterns regarding DOACs in bypass patients. Multivariate logistic regression was performed for 30-day transfusion outcomes, and multiple linear regression was performed for length of stay. RESULTS: Among 9682 patients, 7685 patients received no anticoagulation, whereas 1379 received a vitamin K antagonist (VKA) and 618 received a DOAC postoperatively. Patients receiving anticoagulation compared with no anticoagulation had a higher body mass index and were more likely to have preoperative anemia, congestive heart failure, and atrial fibrillation (all P < .001). Compared with patients receiving VKAs, patients receiving DOACs were less likely to have chronic kidney disease (P = .002) and more likely to have atrial fibrillation (P < .001). The shortest length of stay was among patients receiving no anticoagulation (median, 5 days; interquartile range, 3-9 days; P < .001), followed by DOACs (median, 6 days; interquartile range 3-11 days; P < .001) and VKAs (median, 8 days; interquartile range, 5-13 days; P < .001). Compared with patients receiving VKAs postoperatively, there was no difference in readmission for anticoagulation complications, bypass thrombectomy or thrombolysis, major amputation, or graft patency at 1 year among patients receiving DOACs. On multivariate logistic regression, patients receiving a DOAC (odds ratio, 0.743; confidence interval, 0.59-0.94; P = .011) or no anticoagulation (odds ratio, 0.792; confidence interval, 0.69-0.91; P = .001) were less likely to require transfusion within 30 days than patients taking VKAs. Approximately 70% of the surveyed surgeons reported that they "sometimes" or "always" use DOACs instead of VKAs for protection of a high-risk bypass. CONCLUSIONS: Among patients undergoing lower extremity surgical bypass, those receiving a DOAC postoperatively had a shorter length of stay and were less likely to receive a transfusion in 30 days without compromising graft patency and readmission for anticoagulation complications, thrombectomy, or thrombolysis or affecting amputation rate compared with those receiving a VKA. A majority of surgeons within the quality collaborative have adopted the use of DOACs after peripheral bypass, suggesting the need for a prospective trial evaluating DOAC safety and efficacy in patients requiring anticoagulation for high-risk bypass grafts.

OBJECTIVE: Recent vascular societal guidelines have recommended an abdominal aortic aneurysm (AAA) size threshold for elective intervention; however, limited data have documented how well these AAA diameter benchmarks are being met. The objective of this study was to analyze variation in management of AAAs based on diameter and to determine the physician's rationale for intervention on small AAAs in relation to recommended treatment guidelines. METHODS: A retrospective review of a statewide vascular surgery registry of all elective endovascular or open surgical AAA repairs from January 2012 to January 2016 was performed. Patients were dichotomized on the basis of aortic diameter at time of intervention into either guideline size AAAs or small AAAs, which were defined as <5.5 cm in men, <5.0 cm in women, or with growth <1.0 cm/y. An internal review was conducted of all small AAAs to determine the physician's rationale for intervention. The primary outcomes were variation in adherence to recommended treatment guidelines and the physician's rationale for treatment of small AAAs. Risk-adjusted major complication and mortality rates were calculated at 30 days and 1 year using a propensity score matching analysis. RESULTS: Among the 3932 patients who underwent an elective AAA repair, 485 (12.3%) were repaired at diameters smaller than recommended by guidelines. The median AAA size in the small AAA cohort was 5.1 cm (interquartile range, 4.7-5.3 cm) vs 5.6 cm (interquartile range, 5.2-6.1 cm) in the guideline-based group. Percentage of small AAA repairs varied widely between hospitals from 1.4% to 44.4%. The physician's rationale for the majority of early interventions included the patient's anxiety (12.0%), combined aortoiliac occlusive disease (14.8%), aneurysm anatomy (28.2%), and does not adhere to guidelines (30%). The small AAA cohort had no significant difference in the 30-day or 1-year risk-adjusted mortality in comparison to guideline size AAAs. CONCLUSIONS: Despite well-established aortic diameter threshold guidelines, marked variation exists both at the hospital level and in terms of the physician's rationale for the management of elective AAA repairs. These findings demonstrate the challenge of providing uniform care for patients with AAAs despite established guidelines.

OBJECTIVES: Behavioral intervention is the only treatment for pediatric feeding problems with well documented empirical support. However, parents may be hesitant to pursue behavioral intervention because of concerns about possible negative side effects on child behavioral health and the parent-child relationship. This study investigated associations between behavioral feeding treatment and parenting stress, internalizing and externalizing behavior problems in young children, and parent-child attachment quality. METHODS: Participants included 16 mother-child dyads seeking treatment from a behavioral feeding clinic at a large Midwestern university medical center. Children were between the ages of 30 and 45 months (adjusted) at baseline. Caregivers completed the Child Behavior Checklist for ages 1.5 to 5 (CBCL/1.5-5), the Parenting Stress Index, 3rd Edition Short Form (PSI/SF), and mother-child dyads participated in the Strange Situation procedure at baseline and again after 6 months. The treatment group (nâ=â12) began outpatient behavioral feeding intervention following the baseline evaluation, whereas the control group (nâ=â12) remained on the clinic waitlist until after the 6-month follow-up. RESULTS: The treatment group demonstrated decreases in internalizing and externalizing child behavior problems and parenting stress compared with the control group. No significant differences were demonstrated in parent-child attachment quality within or between groups. CONCLUSIONS: Behavioral feeding intervention had positive effects on perceptions of child emotional and behavioral functioning and maternal parenting stress. Intervention also did not impact the quality of the mother-child attachment relationship. Further research with a larger sample size and additional observational measures of behavior is needed to support the replicability and generalizability of these results.
