Protocol for the perioperative outcome risk assessment with computer learning enhancement (Periop ORACLE) randomized study.
This paper describes a protocol for an ongoing study that hypothesizes that anesthesiology clinicians can predict postoperative complications more accurately with machine learning assistance than without machine learning assistance. This investigation is a sub-study nested within the TECTONICS randomized clinical trial. Study team members who are anesthesiology clinicians working in a telemedicine setting are currently reviewing ongoing surgical cases and documenting how likely they feel the patient is to experience 30-day in-hospital death or acute kidney injury. These case reviews will be randomized to be performed with access to a display showing machine learning predictions for the postoperative complications or without access to the display, and the accuracy of the predictions will be compared across these two groups.

Risk factors for nonresilient outcomes in older adults after total knee replacement.
The purpose of this study was to develop a simple measure of physical resilience and identify risk factors for nonresilient patient outcomes in total knee replacement procedures (TKR). The researchers conducted a secondary analysis of the Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement (FORCE-TJR) cohort study, including 7,239 adults aged 60 or older who underwent TKR between 2011 and 2015. The study found that the variables of age, body mass index, and Charlson Comorbidity Index (CCI) were associated with increased risk of physically nonresilient outcomes across the 3 patient-reported outcomes of the physical component summary (PCS), bodily pain (BP), and vitality (VT). A household income of greater than $45 000 associated with lower risk for PCS (RR = 0.81 [0.70-0.93]), BP (RR = 0.80 [0.69-0.91]), and VT (RR = 0.86 [0.78-0.93]). CONCLUSIONS: We operationalized physical resilience and identified factors predicting resilience after TKR. This approach may aid clinical risk stratification, guide further investigation of causes, and ultimately aid patients through the design of interventions to enhance physical resilience.

Association between race and perioperative outcomes after carotid endarterectomy for asymptomatic carotid artery stenosis in NSQIP.
This study investigated the association of race on carotid endarterectomy (CEA) outcomes. Perioperative outcomes (at 30 days) were compared for Black vs. White patients adjusting for age/sex, comorbidities and disease characteristics. Out of 16,764 patients from the ACS-NSQIP targeted vascular database (2011-2019), 95.2% were White and 4.8% were Black. Black patients were slightly younger and more frequently (79.5% vs 74.0%) had high-grade carotid artery stenosis compared to White patients. Comorbidities including hypertension, diabetes, kidney disease, congestive heart failure, and coronary artery disease were all more prevalent among Black patients. Crude perioperative stroke and stroke/death were higher for Black patients, but myocardial infarction leading to death were similar. After adjusting for baseline differences between groups, the risk of perioperative stroke and stroke/death remained significantly higher for Black patients than White patients.

Short-term risk of performing concurrent procedures with hepatic artery infusion pump placement.
This study’s objective was to characterize the short-term outcomes of concurrent surgery with hepatic artery infusion pump (HAIP) placement using data from the 2005-2017 ACS NSQIP dataset. Findings showed that HAIP placement is not associated with additional morbidity when performed with hepatic and/or colorectal surgery. Decisions regarding HAIP placement should consider the risks of concurrent operations as well as patient- and disease-specific factors.

Exposure to general anesthesia for cesarean delivery and odds of severe postpartum depression requiring hospitalization.
This retrospective cohort study evaluated the risk of general anesthesia use in cesarean delivery versus neuraxial anesthesia on maternal mental health. Cesarean deliveries performed in New York State hospitals between 2006 and 2013 were included. Exclusion criteria included having more than 1 cesarean delivery during the study period, residing outside of New York State, and having a general anesthetic for other surgery or delivery in the year before or after the index case. The primary outcome looked at was severe postpartum depression (PPD), and secondary outcomes were suicidal ideation, anxiety disorders, and posttraumatic stress disorder (PTSD). The majority of cesareans used neuraxial anesthesia and only 8% (34,356) had general anesthesia. Severe PPD requiring hospitalization occurred in 1158 women with 60% identified during readmission. General anesthesia was found to be associated with a 54% increased odds of PPD, and a 91% increased odds of suicidal ideation or self-inflicted injury. There was insufficient evidence for increased risk of anxiety orders.

Evaluating the impact of pneumonia prevention recommendations after cardiac surgery.
Pneumonia is the most prevalent healthcare-associated infection after coronary artery bypass grafting (CABG), but the relative effectiveness of strategies to reduce its incidence remains unclear. In this study, the investigators evaluated the relationship between healthcare-associated infection recommendations and risk of pneumonia after CABG. These pneumonia prevention recommendations may serve as effective targets for avoiding postoperative healthcare-associated infections.

Post-discharge venous thromboembolism after pancreatectomy for malignancy: predicting risk based on preoperative, intraoperative, and postoperative factors.
Extended chemoprophylaxis is recommended for high-risk patients following pancreatectomy for malignancy. However, quantifying risk remains difficult. In this study, the investigators sought to (a) identify factors associated with post-discharge venous thromboembolism (VTE) following pancreatectomy for malignancy and (b) develop a post-discharge VTE risk calculator to identify high-risk patients. The investigators concluded that preoperative, intraoperative, and postoperative factors were associated with post-discharge VTE following pancreatectomy for malignancy.

Importance of long-term follow-up after endoscopic management for upper tract urothelial carcinoma and factors leading to surgical management.
Patients undergoing endoscopic management for upper tract urothelial carcinoma often progress to definitive therapy with radical nephroureterectomy. This study examined the rate of progression as well as risk factors for transitions in treatment over time. The investigators found that patients who progressed to radical nephroureterectomy after endoscopic management had fewer comorbid conditions and changes in disease status including visible lesions on ureteroscopy and positive biopsies.

Rates, risk factors, and complications of red blood cell transfusion in metastatic spinal tumor surgery: an analysis of a prospective multicenter surgical database.
The goal of this study was to identify rates, risks, and complications of red blood cell (RBC) transfusion in metastatic spinal tumor surgery. The multicenter prospective American College of Surgeons National Quality Improvement Program database was used to identify adult patients with disseminated cancer who underwent metastatic spinal tumor surgery from 2012-2016. A patient was included if at least 1 intraoperative/postoperative RBC transfusion was received within the first 72 hours of surgery start time. Out of 1601 patients included, 623 (38.9%) received a RBC transfusion. There was an overall higher complication rate in patients who received a transfusion compared to those who didn’t. These complications included sepsis (3.5% vs. 1.9%), deep vein thrombosis (6.1% vs. 3.3%), and prolonged ventilation (3.9% vs. 1.3%). Future research into complication prevention was recommended.

Comparison of accuracy of prediction of postoperative mortality and morbidity between a new, parsimonious risk calculator (SURPAS) and the ACS Surgical Risk Calculator.
The purpose of this study was to compare the accuracy of the Surgical Risk Preoperative Assessment System (SURPAS) to that of the American College of Surgeons Surgical Risk Calculator (ACS-SRC). Data from 1006 selected ACS National Surgical Quality Improvement Program (NSQIP) patients with known outcomes were used to calculate predicted risk of postoperative mortality and morbidity. Findings showed that the SURPAS risk predictions were more accurate than the ACS-SRC's for overall morbidity, particularly for high risk patients.

Margin positivity in resectable esophageal cancer: are there modifiable risk factors?
Patients with esophageal cancer have poor overall survival, with positive resection margins worsening survival. Margin positivity rates are used as quality measures in other malignancies, but modifiable risk factors are necessary to develop actionable targets for improvement. The objectives of this study were to (1) evaluate trends in esophageal cancer margin positivity, and (2) identify modifiable patient/hospital factors associated with margin positivity.

Increased-risk donors and solid organ transplantation: current practices and opportunities for improvement.
This study looked at recent developments in decision making for use of CDC-labeled increased-risk donor (IRD) use for solid organ transplantation. The implementation of nucleic acid testing for HIV and hepatitis C virus has resulted in decreasing risk of window-period infection often by an order of magnitude or more. However, surgeons still are hesitant to utilize IRD organs. The authors conclude that rate of transmission of window-period infection from IRD organs is exceptionally low and the harms regarding the increased risk classification outweigh the benefits for patients who need organ transplantation.

Hirschsprung-associated enterocolitis in children treated at US children's hospitals.
The incidence of and risk factors for Hirschsprung's-associated enterocolitis (HAEC) following pull-through have been limited to single institutions studies. In this retrospective cohort study, the investigators characterized the incidence of, risk factors for, and consequences of post-operative HAEC. The investigators concluded that HAEC following pull-through occurs in a large proportion of infants with HD and predicts reoperation. They suggest that multicenter studies are needed to develop prediction models and treatment protocols for HAEC.

Post-operative complications and readmissions associated with smoking following bariatric surgery.
The link between smoking and poor postoperative outcomes is well established. Despite this, current smokers are still offered bariatric surgery. In this study, the investigators describe the risk of postoperative 30-day complications and readmission following laparoscopic sleeve gastrectomy and laparoscopic Roux-En-Y gastric bypass in smokers. The investigators concluded that smokers undergoing bariatric surgery experienced significantly worse 30-day outcomes when compared with non-smokers.

Readmission after spinal epidural abscess management in urban populations: a bi-institutional study.
This study examined 90-day readmission rates and causes after spinal epidural abscess (SEA) occurrence in urban populations. Neurosurgery records from two large urban institutions were reviewed to identify patients who were treated with SEA. Out of 103 patients with identified SEA, 97 were included. The mean age was 57.1 years and 57.7% were male. The 90-readmission rate for all causes was 37.1% with infection being the most common cause. Patients with prior immunocompromised status or hepatic disease had higher odds of 90-day readmission after SEA treatment.

Frailty as a predictor of death or new disability after surgery: a prospective cohort study.
The purpose of this study was to compare the accuracy of the modified Fried Index (mFI) and the Clinical Frailty Scale (CFS) to predict death or patient-reported new disability 90 days after major elective surgery. Results showed that older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery and that although accuracy was similar, the CFS, compared to the mFI, was easier to use and feasibility was higher.

Hospital experience predicts outcomes after high-risk geriatric surgery.
This study examined if there an association between a hospital’s annual volume of high-risk geriatric surgery and their risk of inpatient mortality, postoperative length of stay, and discharge to nursing facility. Using the 2014 National Inpatient Sample, older adults were identified who had undergone high-risk geriatric surgery. There were an estimated 514,950 hospital encounters at 3,115 hospitals undergoing surgery. A higher proportion of high-risk geriatric surgery patients was associated with decreased mortality and shorter postoperative length of stay. Higher volume hospitals were not associated with mortality but was associated with longer length of stay and decreased discharge to nursing facilities.

Long-term functional decline after high-risk elective colorectal surgery in older adults.
This study examined the long-term risks of functional decline after elective colorectal surgery in older adults. This retrospective matched cohort study used data from the Health and Retirement Study, a nationally representative, longitudinal survey of adults >50 years of age. This survey collected data on functional status, cognition, and demographics, among other topics. The survey was linked with Medicare claims and National Death Index data from 1992 to 2012 and used patients 65 years and older. Surgery patients did experience a greater likelihood of functional decline with or without complications compared to control subjects. The older the patient, the more likelihood of a functional decline occurring after surgery.

Pre-operative, intra-operative, and post-operative factors associated with post-discharge venous thromboembolism following colorectal cancer resection.
Venous thromboembolism (VTE) is the most common preventable cause of 30-day post-operative mortality, with many events occurring after hospital discharge. High-level evidence supports post-discharge VTE chemoprophylaxis following abdominal/pelvic cancer resection; however, some studies support a more tailored approach. The objectives of this study were to (1) identify risk factors associated with post-discharge VTE in a large cohort of patients undergoing colorectal cancer resection and (2) develop a post-discharge VTE risk calculator.

Association of cardiac rehabilitation with decreased hospitalization and mortality risk after cardiac valve surgery.
Investigators sought to characterize cardiac rehabilitation (CR) enrollment after cardiac valve surgery and its association with outcomes, including hospitalizations and mortality. Subjects were all fee-for-service Medicare beneficiaries undergoing open cardiac valve surgery in 2014, identified by inpatient diagnosis codes for open aortic, mitral, tricuspid, and pulmonary valve surgery. They found that fewer than half of Medicare beneficiaries undergoing cardiac valve surgery enrolled in CR programs, and there were marked racial/ethnic disparities among those who do. They recommend further study on barriers to CR enrollment in this population.

Centralization of high-risk cancer surgery within existing hospital systems.
Centralization is often proposed as a strategy to improve the quality of certain high-risk health care services. In this study, the investigators evaluated the extent to which existing hospital systems centralize high-risk cancer surgery and whether centralization is associated with short-term clinical outcomes. The investigators concluded that greater centralization of complex cancer surgery within existing hospital systems was associated with better outcomes.

Development of comorbidity score for patients undergoing major surgery.
The goal of this study was to develop and validate a claims-based comorbidity score and compare to established comorbidity scores. The researchers used Medicare data to find adults 65 and older who had undergone major surgery to predict 1-year mortality, and 30-day hospital readmission. The comorbidity score was compared to the Charlson, Elixhauser, and CMC-HCC scores. Their newly developed comorbidity score better predicted outcomes than the established comorbidity score systems in the surgical population.
