Does a delay to surgery for preoperative echocardiogram affect outcomes in patients with hip fracture? OTA Int 2024; 7:e338. [PMID: 38863460 PMCID: PMC11164006 DOI: 10.1097/oi9.0000000000000338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 04/10/2024] [Accepted: 04/16/2024] [Indexed: 06/13/2024]
Abstract
Introduction Delay to surgery >24 hours has been shown to correlate with mortality rates in patients with hip fracture when left untreated. Many of these patients have multiple comorbidities, including aortic stenosis (AS), and undergo workup for operative clearance, which may delay time to surgery. The purpose of this study was to examine whether preoperative echocardiogram workup affects time to surgery, complications, and mortality after operative fixation for hip fracture. Methods Our institutional hip fracture registry was retrospectively reviewed for inclusion over a 3-year period. Patients who had a preoperative echocardiogram (yECHO) for operative clearance were compared with those who did not (nECHO). Demographic data, time to surgery, overall complication rate, and mortality at 30 days, 90 days, and 1 year were collected. Results Two cohorts consisted of 136 yECHO patients (45.8%) and 161 nECHO patients (54.2%). Thirty-two yECHO patients (23.5%) had AS. Patients in the yECHO cohort were more likely to have a complication for any cause compared with nECHO patients (25.7% vs. 10.6%, P = 0.01) and have a higher mortality rate at 1 year (38.9% vs. 17.4%, P = 0.001). There was no association found between AS and all-cause complication (P = 0.54) or 30-day (P = 0.13) or 90-day mortality rates (P = 0.79). However, patients with AS had a significantly higher mortality rate at 1 year (45.8% vs. 25.1%, P = 0.03). Conclusion This study reinforces the benefits of ensuring less than a 24-hour time to surgery in the setting of a hip fracture and identifies an area of preoperative management that can be further optimized to prevent unnecessary prolongation in time to surgery. Patients with known aortic stenosis are not associated with increased 30-day or 90-day mortality or all-cause complications. Surgical delays in the yECHO cohort were attributed to preoperative medical assessments, including echocardiograms and the management of comorbidities. Therefore, the selective utilization of preoperative echocardiograms is needed and should be reserved to ensure they have a definitive role in guiding the perioperative care of patients with hip fracture. Level of Evidence III.

Abstract
BACKGROUND Risk assessment is critically important in elective and high-risk interventions, particularly spine surgery. This narrative review describes the evolution of risk assessment from the earliest instruments focused on general surgical risk stratification, to more accurate and spine-specific risk calculators that quantified risk, to the current era of big data. METHODS The PubMed and SCOPUS databases were queried on October 11, 2023 using search terms to identify risk assessment tools (RATs) in spine surgery. A total of 108 manuscripts were included after screening with full-text review using the following inclusion criteria: 1) study population of adult spine surgical patients, 2) studies describing validation and subsequent performance of preoperative RATs, and 3) studies published in English. RESULTS Early RATs provided stratified patients into broad categories and allowed for improved communication between physicians. Subsequent risk calculators attempted to quantify risk by estimating general outcomes such as mortality, but then evolved to estimate spine-specific surgical complications. The integration of novel concepts such as invasiveness, frailty, genetic biomarkers, and sarcopenia led to the development of more sophisticated predictive models that estimate the risk of spine-specific complications and long-term outcomes. CONCLUSIONS RATs have undergone a transformative shift from generalized risk stratification to quantitative predictive models. The next generation of tools will likely involve integration of radiographic and genetic biomarkers, machine learning, and artificial intelligence to improve the accuracy of these models and better inform patients, surgeons, and payers.

Abstract
PURPOSE OF REVIEW Given the rapid growth of nonoperating room anesthesia (NORA) in recent years, it is essential to review its unique challenges as well as strategies for patient selection and care optimization. RECENT FINDINGS Recent investigations have uncovered an increasing prevalence of older and higher ASA physical status patients in NORA settings. Although closed claim data regarding patient injury demonstrate a lower proportion of NORA cases resulting in a claim than traditional operating room cases, NORA cases have an increased risk of claim for death. Challenges within NORA include site-specific differences, limitations in ergonomic design, and increased stress among anesthesia providers. Several authors have thus proposed strategies focusing on standardizing processes, site-specific protocols, and ergonomic improvements to mitigate risks. SUMMARY Considering the unique challenges of NORA settings, meticulous patient selection, risk stratification, and preoperative optimization are crucial. Embracing data-driven strategies and leveraging technological innovations (such as artificial intelligence) is imperative to refine quality control methods in targeted areas. Collaborative efforts led by anesthesia providers will ensure personalized, well tolerated, and improved patient outcomes across all phases of NORA care.

A Closer Look into the Nationwide Danish Cohort. J Cardiothorac Vasc Anesth 2024; 38:1707-1715. [PMID: 38789284 DOI: 10.1053/j.jvca.2024.03.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 02/27/2024] [Accepted: 03/20/2024] [Indexed: 05/26/2024]
Abstract
OBJECTIVE General anesthesia (GA) may impair outcome after vascular surgery. The use of anticoagulant medication is often used in patients with cardiac comorbidity. Regional anesthesia (RA) requires planning of discontinuation before neuraxial blockade(s) in this subgroup. This study aimed to describe the effect of anesthesia choice on outcome after vascular surgery in patients with known cardiac comorbidity. DESIGN Retrospective cohort study. SETTING Danish hospitals. PARTICIPANTS 6302 patients with known cardiac comorbidity, defined as ischemic heart disease, valve disease, pulmonary vascular disease, heart failure, and cardiac arrhythmias, undergoing lower extremity vascular surgery between 2005 and 2017. INTERVENTIONS GA versus RA. MEASUREMENTS AND MAIN RESULTS Data were extracted from national registries. GA was defined as anesthesia with mechanical ventilation. Multivariable regression models were used to describe the incidence of postoperative complications as well as 30-day mortality, hypothesizing that better outcomes would be seen after RA. The rate of RA decreased from 48% in 2005 to 20% in 2017. The number of patients with 1 or more complications was 9.7% vs 6.2% (p < 0.001), and 30-day mortality was 6.0% vs 3.4% (p < 0.001) after GA. After adjusting for baseline differences, the odds ratio (OR) was significantly lower for medical complications (cardiac, pulmonary, renal, new dialysis, intensive care unit and other medical complications; OR, 0.97; 95% confidence interval [CI], 0.95-0.98) and 30-day mortality (OR 0.98; 95% CI, 0.97-0.99) after RA. CONCLUSIONS RA may be associated with a better outcome than GA after lower extremity vascular surgery in patients with a cardiac comorbidity. Prioritizing RA, despite the inconvenience of discontinuing anticoagulants, may be recommended.

Abstract
BACKGROUND The relationship between postoperative adverse events and blood pressures in the preoperative period remains poorly understood. This study tested the hypothesis that day-of-surgery preoperative blood pressures are associated with postoperative adverse events. METHODS The authors conducted a retrospective, observational study of adult patients having elective procedures requiring an inpatient stay between November 2017 and July 2021 at Vanderbilt University Medical Center to examine the independent associations between preoperative systolic and diastolic blood pressures (SBP, DBP) recorded immediately before anesthesia care and number of postoperative adverse events-myocardial injury, stroke, acute kidney injury, and mortality-while adjusting for potential confounders. The study used multivariable ordinal logistic regression to model the relationship. RESULTS The analysis included 57,389 cases. The overall incidence of myocardial injury, stroke, acute kidney injury, and mortality within 30 days of surgery was 3.4% (1,967 events), 0.4% (223), 10.2% (5,871), and 2.1% (1,223), respectively. The independent associations between both SBP and DBP measurements and number of postoperative adverse events were found to be U-shaped, with greater risk both above and less than SBP 143 mmHg and DBP 86 mmHg-the troughs of the curves. The associations were strongest at SBP 173 mmHg (adjusted odds ratio, 1.212 vs. 143 mmHg; 95% CI, 1.021 to 1.439; P = 0.028), SBP 93 mmHg (adjusted odds ratio, 1.339 vs. 143 mmHg; 95% CI, 1.211 to 1.479; P < 0.001), DBP 106 mmHg (adjusted odds ratio, 1.294 vs. 86 mmHg; 95% CI, 1.003 to 1.17671; P = 0.048), and DBP 46 mmHg (adjusted odds ratio, 1.399 vs. 86 mmHg; 95% CI, 1.244 to 1.558; P < 0.001). CONCLUSIONS Preoperative blood pressures both less than and above a specific threshold were independently associated with a higher number of postoperative adverse events, but the data do not support specific strategies for managing patients with low or high blood pressure on the day of surgery.

Abstract
A team comprising nursing, medical staff, and administrative leaders at an urban academic orthopedic hospital in the northeastern United States sought to revise a preoperative laboratory testing protocol based on evidence and practice guidelines. The goal was to decrease unnecessary tests by 20% without negatively affecting patient outcomes. After adding the revised protocol to the electronic health record, audits revealed that the target goal was not met and additional strategies were implemented, including educational webinars for surgeon office personnel who ordered tests, additional webinars for advanced practice professionals, and the creation of scorecards to track surgeons' progress. Overall, a downward trend in the ordering of unnecessary laboratory tests for patients without identified risks was observed, but a 20% reduction was not achieved. Surgical complications during the project were not associated with laboratory tests. Clinicians continue to use the revised preoperative laboratory testing protocol at the facility.

Abstract
BACKGROUND Obesity is known as a risk factor for cardiovascular disease (CVD). However, there is an absence of preoperative cardiac risk assessment in bariatric surgery candidates and the incidence of CVD among these high-risk patients is still unknown. METHODS A consecutive series of bariatric surgery candidates at two Chinese tertiary hospitals received coronary CT angiography or coronary angiography from 2017 to 2023. Patients were categorized as metabolically unhealthy obesity (MUO) and metabolically healthy obesity (MHO) based on the presence or absence of MetS. CVD was diagnosed based on the maximum intraluminal stenosis > 1% in any of the segments of the major epicardial coronary arteries. Obstructive CVD was defined as coronary stenosis ≥ 50%. Binary multivariable logistic regression was performed to analyze the association between CVD and metabolic status. The number of principal MetS components was categorized into zero (without glycemic, lipid, and BP components), one (with one of the components), two (with any two components), and three (with all components) to explore their association with CVD. RESULTS A total of 1446 patients were included in the study. The incidence of CVD and obstructive CVD were 31.7% and 9.6%. Compared with MHO patients, MUO patients had a significantly higher incidence of mild (13.7% vs. 6.1%, P < 0.05), moderate (7.4% vs. 0.8%, P < 0.05), and severe CVD (3.1% vs. 0%, P < 0.05). Following complete adjustment, compared with zero or one component, two principal MetS components was found to be associated with a notable increase in the risk of CVD (OR 2.05, 95% CI 1.18-3.58, P < 0.05); three principal MetS components were observed to have a higher risk of CVD and obstructive CVD (OR 2.68, 95% CI 1.56-4.62, P < 0.001; OR 3.93, 95% CI 1.19-12.93, P < 0.05). Each increase in the number of principal MetS components correlated with a 1.47-fold (95% CI 1.20-1.81, P < 0.001) and 1.78-fold (95% CI 1.24-2.55, P < 0.05) higher risk of CVD and obstructive CVD, respectively. CONCLUSION This study reported the incidence of CVD based on multicenter bariatric surgery cohorts. CVD is highly prevalent in patients with obesity, especially in MUO patients. Increased number of principal MetS components will significantly elevate the risk of CVD.

Abstract
BACKGROUND Patients with peripheral arterial disease have an increased risk of developing cardiovascular complications in the postoperative period of arterial surgeries known as Major Adverse Cardiac Events (MACE), which includes acute myocardial infarction, heart failure, malignant arrhythmias, and stroke. The preoperative evaluation aims to reduce mortality and the risk of MACE. However, there is no standardized approach to performing them. The aim of this study was to compare the preoperative evaluation conducted by general practitioners with those performed by cardiologists. METHODS This is a retrospective analysis of medical records of patients who underwent elective arterial surgeries from January 2016 to December 2020 at a tertiary hospital in São Paulo, Brazil. The authors compared the preoperative evaluation of these patients according to the initial evaluator (general practitioners vs. cardiologists), assessing patients' clinical factors, mortality, postoperative MACE incidence, rate of requested non-invasive stratification tests, length of hospital stay, among others. RESULTS 281 patients were evaluated: 169 assessed by cardiologists and 112 by general practitioners. Cardiologists requested more non-invasive stratification tests (40.8%) compared to general practitioners (9%) (p < 0.001), with no impact on mortality (8.8% versus 10.7%; p = 0.609) and postoperative MACE incidence (10.6% versus 6.2%; p = 0.209). The total length of hospital stay was longer in the cardiologist group (17.27 versus 11.79 days; p < 0.001). CONCLUSION The increased request for exams didn't have a significant impact on mortality and postoperative MACE incidence, but prolonged the total length of hospital stay. Health managers should consider these findings and ensure appropriate utilization of human and financial resources.

Abstract
BACKGROUND Postoperative myocardial infarction (POMI) is associated with major surgeries and remains the leading cause of mortality and morbidity in people undergoing vascular surgery, with an incidence rate ranging from 5% to 20%. Preoperative coronary interventions, such as coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCI), may help prevent acute myocardial infarction in the perioperative period of major vascular surgery when used in addition to routine perioperative drugs (e.g. statins, angiotensin-converting enzyme inhibitors, and antiplatelet agents), CABG by creating new blood circulation routes that bypass the blockages in the coronary vessels, and PCI by opening up blocked blood vessels. There is currently uncertainty around the benefits and harms of preoperative coronary interventions. OBJECTIVES To assess the effects of preoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery. SEARCH METHODS We searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, and CINAHL EBSCO on 13 March 2023. We also searched the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov. SELECTION CRITERIA We included all randomised controlled trials (RCTs) or quasi-RCTs that compared the use of preoperative coronary interventions plus usual care versus usual care for preventing acute myocardial infarction during major open vascular or endovascular surgery. We included participants of any sex or any age undergoing major open vascular surgery, major endovascular surgery, or hybrid vascular surgery. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes of interest were acute myocardial infarction, all-cause mortality, and adverse events resulting from preoperative coronary interventions. Our secondary outcomes were cardiovascular mortality, quality of life, vessel or graft secondary patency, and length of hospital stay. We reported perioperative and long-term outcomes (more than 30 days after intervention). We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included three RCTs (1144 participants). Participants were randomised to receive either preoperative coronary revascularisation with PCI or CABG plus usual care or only usual care before major vascular surgery. One trial enrolled participants if they had no apparent evidence of coronary artery disease. Another trial selected participants classified as high risk for coronary disease through preoperative clinical and laboratorial testing. We excluded one trial from the meta-analysis because participants from both the control and the intervention groups were eligible to undergo preoperative coronary revascularisation. We identified a high risk of performance bias in all included trials, with one trial displaying a high risk of other bias. However, the risk of bias was either low or unclear in other domains. We observed no difference between groups for perioperative acute myocardial infarction, but the evidence is very uncertain (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.02 to 4.57; 2 trials, 888 participants; very low-certainty evidence). One trial showed a reduction in incidence of long-term (> 30 days) acute myocardial infarction in participants allocated to the preoperative coronary interventions plus usual care group, but the evidence was very uncertain (RR 0.09, 95% CI 0.03 to 0.28; 1 trial, 426 participants; very low-certainty evidence). There was little to no effect on all-cause mortality in the perioperative period when comparing the preoperative coronary intervention plus usual care group to usual care alone, but the evidence is very uncertain (RR 0.79, 95% CI 0.31 to 2.04; 2 trials, 888 participants; very low-certainty evidence). The evidence is very uncertain about the effect of preoperative coronary interventions on long-term (follow up: 2.7 to 6.2 years) all-cause mortality (RR 0.74, 95% CI 0.30 to 1.80; 2 trials, 888 participants; very low-certainty evidence). One study reported no adverse effects related to coronary angiography, whereas the other two studies reported five deaths due to revascularisations. There may be no effect on cardiovascular mortality when comparing preoperative coronary revascularisation plus usual care to usual care in the short term (RR 0.07, 95% CI 0.00 to 1.32; 1 trial, 426 participants; low-certainty evidence). Preoperative coronary interventions plus usual care in the short term may reduce length of hospital stay slightly when compared to usual care alone (mean difference -1.17 days, 95% CI -2.05 to -0.28; 1 trial, 462 participants; low-certainty evidence). We downgraded the certainty of the evidence due to concerns about risk of bias, imprecision, and inconsistency. None of the included trials reported on quality of life or vessel graft patency at either time point, and no study reported on adverse effects, cardiovascular mortality, or length of hospital stay at long-term follow-up. AUTHORS' CONCLUSIONS Preoperative coronary interventions plus usual care may have little or no effect on preventing perioperative acute myocardial infarction and reducing perioperative all-cause mortality compared to usual care, but the evidence is very uncertain. Similarly, limited, very low-certainty evidence shows that preoperative coronary interventions may have little or no effect on reducing long-term all-cause mortality. There is very low-certainty evidence that preoperative coronary interventions plus usual care may prevent long-term myocardial infarction, and low-certainty evidence that they may reduce length of hospital stay slightly, but not cardiovascular mortality in the short term, when compared to usual care alone. Adverse effects of preoperative coronary interventions were poorly reported in trials. Quality of life and vessel or graft patency were not reported. We downgraded the certainty of the evidence most frequently for high risk of bias, inconsistency, or imprecision. None of the analysed trials provided significant data on subgroups of patients who could potentially experience more substantial benefits from preoperative coronary intervention (e.g. altered ventricular ejection fraction). There is a need for evidence from larger and homogeneous RCTs to provide adequate statistical power to assess the role of preoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery.

Abstract
BACKGROUND Surgical risk stratification is crucial for enhancing perioperative assistance and allocating resources efficiently. However, existing models may not capture the complexity of surgical care in Brazil. Using data from various healthcare settings nationwide, we developed a new risk model for 30-day in-hospital mortality (the Ex-Care BR model). METHODS A retrospective cohort study was conducted in 10 hospitals from different geographic regions in Brazil. Data were analysed using multilevel logistic regression models. Model performance was assessed using the area under the receiver operating characteristic curve (AUROC), Brier score, and calibration plots. Derivation and validation cohorts were randomly assigned. RESULTS A total of 107,372 patients were included, and 30-day in-hospital mortality was 2.1% (n=2261). The final risk model comprised four predictors related to the patient and surgery (age, ASA physical status classification, surgical urgency, and surgical size), and the random effect related to hospitals. The model showed excellent discrimination (AUROC=0.93, 95% confidence interval [CI], 0.93-0.94), calibration, and overall performance (Brier score=0.017) in the derivation cohort (n=75,094). Similar results were observed in the validation cohort (n=32,278) (AUROC=0.93, 95% CI, 0.92-0.93). CONCLUSIONS The Ex-Care BR is the first model to consider regional and organisational peculiarities of the Brazilian surgical scene, in addition to patient and surgical factors. It is particularly useful for identifying high-risk surgical patients in situations demanding efficient allocation of limited resources. However, a thorough exploration of mortality variations among hospitals is essential for a comprehensive understanding of risk. CLINICAL TRIAL REGISTRATION NCT05796024.

[PMID: 38382579 DOI: 10.1016/j.jjcc.2024.02.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/29/2023] [Accepted: 02/14/2024] [Indexed: 02/23/2024]
Abstract
BACKGROUND The AUB-HAS2 Cardiovascular Risk Index is a newly derived tool for preoperative cardiovascular evaluation. It is based on six data elements: history of heart disease, symptoms of angina or dyspnea, age ≥ 75 years, hemoglobin < 12 g/dl, vascular surgery, and emergency surgery. This study compares the performance of this new index among emergency and elective surgeries. METHODS AND RESULTS The study population consisted of 1,167,414 non-cardiac surgeries registered in the American College of Surgeons National Surgical Quality Improvement Program database (153,715 were emergency and 1,013,699 were elective). Each patient was given an AUB-HAS2 score of 0, 1, 2, 3, or >3 depending on the number of data elements s/he has. The outcome measure (death, myocardial infarction, or stroke at 30 days after surgery) was higher in emergency than elective surgeries (7.0 % vs 1.4 %, p < 0.0001). The AUB-HAS2 index was able to stratify risk in both types of surgeries with a gradual increase in risk as the score increased (p < 0.0001). The discriminatory power of the AUB-HAS2 index, measured by the area under the receiver operator characteristic curves, was good and similar in the two types of surgeries (0.804 for emergency vs 0.791 for elective surgeries). CONCLUSION The AUB-HAS2 index is a versatile tool that can effectively and equally stratify risk in both emergency and elective surgeries with a good discriminatory power.

Abstract
BACKGROUND A model developed specifically for stable coronary artery disease (SCAD) patients to predict perioperative major adverse cardiovascular events (MACE) has not been previously reported. METHODS The derivation cohort consisted of 5780 patients with SCAD undergoing noncardiac surgery at the First Affiliated Hospital of Zhejiang University School of Medicine, from January 1, 2013 until May 31, 2021. The validation cohort consisted of 2677 similar patients from June 1, 2021 to May 31, 2023. The primary outcome was a composite of MACEs (death, resuscitated cardiac arrest, myocardial infarction, heart failure, and stroke) intraoperatively or during hospitalization postoperatively. RESULTS Six predictors, including Creatinine >90 μmol/L, Hemoglobin <110 g/L, Albumin <40 g/L, Leukocyte >10 ×109/L, high-risk Surgery (general abdominal or vascular), and American Society of Anesthesiologists (ASA) class (III or IV), were selected in the final model (CHALSA score). Each patient was assigned a CHALSA score of 0, 1, 2, 3, or > 3 according to the number of predictors present. The incidence of perioperative MACEs increased steadily across the CHALSA score groups in both the derivation (0.5%, 1.4%, 2.9%, 6.8%, and 23.4%, respectively; p < 0.001) and validation (0.3%, 1.5%, 4.1%, 9.2%, and 29.2%, respectively; p < 0.001) cohorts. The CHALSA score had a higher discriminatory ability than the revised cardiac risk index (C statistic: 0.827 vs. 0.695 in the validation dataset; p < 0.001). CONCLUSIONS The CHALSA score showed good validity in an external dataset and will be a valuable bedside tool to guide the perioperative management of patients with SCAD undergoing noncardiac surgery.

Effect of continuing angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers on the day of surgery on myocardial injury after non-cardiac surgery: A retrospective cohort study. J Clin Anesth 2024; 94:111401. [PMID: 38330844 DOI: 10.1016/j.jclinane.2024.111401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 01/17/2024] [Accepted: 01/23/2024] [Indexed: 02/10/2024]
Abstract
STUDY OBJECTIVE To evaluate the effect of continuing of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) prescriptions 24 h before surgery on postoperative myocardial injury and blood pressure in patients undergoing non-cardiac surgery. DESIGN A single-center, retrospective study. SETTING Operating room and perioperative care area. PATIENTS 42,432 patients who had been taking chronic ACEI/ARB underwent non-cardiac surgery from January 2012 to June 2022. INTERVENTIONS Patients who discontinued ACEI/ARB 24 h before surgery (withheld group, n=31,055) and those who continued ACEI/ARB 24 h before surgery (continued group, n=11,377). MEASUREMENTS Primary outcome was myocardial injury after non-cardiac surgery (MINS) within 7 days postoperatively. MINS was defined as an elevated postoperative cardiac troponin measurement above the 99th percentile of the upper reference limit with a rise/fall pattern. Perioperative blood pressure and clinical outcomes were secondary outcomes. MAIN RESULTS Among 42,432 patients, MINS occurred in 2848 patients (6.7%) and was the all-cause of death within 30 days in 122 patients (0.3%). Incidence of MINS was significantly higher in the continued group than the withheld group (847/11,377 [7.4%] vs. 2001/31,055 [6.4%]; OR [95% CI] 1.17 [1.07-1.27]; P<0.001). After 1:1 propensity score matching, 11,373 patients were included in each group. There was still a significant difference for the occurrence of MINS between two groups in matched cohort (7.4% vs. 6.6%, OR [95% CI] 1.14 [1.03-1.26]; P=0.015). Time-average weight of mean arterial pressure <65 mmHg during surgery was significantly higher in the continued group (mean 0.11 vs. 0.09 [95% CI of mean difference] [0.01-0.03]; P<0.001). However, there was no significant difference in other clinical outcomes and mortality. CONCLUSIONS Withholding ACEI/ARB before surgery was associated with a reduced risk of intraoperative hypotension and postoperative myocardial injury, but it did not affect overall clinical outcomes in patients undergoing non-cardiac surgery.

Abstract
BACKGROUND Major vascular surgery is associated with a high perioperative risk and significant mortality. Despite advances in risk stratification, monitoring, and management of perioperative complications, cardiac complications are still common. Stress echocardiography is well established in coronary artery disease diagnostics; however, its prognostic value before high-risk aortic surgery is unknown. This prospective, single-center study compared the outcome of patients undergoing extended cardiac risk assessment before open abdominal aortic surgery with the outcome of patients who had received standard preoperative assessment. METHODS The study included patients undergoing elective open abdominal aortic surgery. Patients who underwent standard preoperative assessment before the start of a dedicated protocol were compared with patients who had extended cardiac risk assessment, including dobutamine stress echocardiography, as part of a stepwise interdisciplinary cardiovascular team approach. The combined primary endpoint was cardiovascular death, myocardial infarction, emergency coronary revascularization, and life-threatening arrhythmia within 30 days. The secondary endpoint was acute renal failure and severe bleeding. RESULTS In total, 77 patients (mean age 68.1 ± 8.1 years, 70% male) were included: 39 underwent standard and 38 underwent cardiac risk assessment. The combined primary endpoint was reached significantly more often in patients before than after implementation of the extended cardiac stratification procedure (15% vs. 0%, p = 0.025). The combined secondary endpoint did not differ between the groups. CONCLUSIONS Patients with extended cardiac risk assessment undergoing elective open abdominal aortic surgery had better 30-day outcomes than did those who had standard preoperative assessment.

Abstract
Introduction Indications for HSCT are increasing worldwide, paralleled by a growing demand for donors of therapeutic cells. Methods Herein, we report our real-world experience of adult HPC donor assessment during a 5-year study period (2018-2023): we have retrospectively revised data of 455 potential related stem cell donors, consecutively evaluated at our center. Donor medical history was assessed by a questionnaire and an interview with a trained physician experienced in donation procedures to evaluate donor fitness and medical history. Pre-existing health disorders were fully investigated. Behavioral risk factors for communicable infectious diseases were also routinely explored. Results and discussion Overall, 351 donors were finally assessed as eligible for HPC donation, and 233 underwent stem cell collection, 158 through apheresis from mobilized peripheral blood, and 75 through bone marrow harvest. Among them, 27 donors were selected despite the presence of pre-existing health conditions, which would be potential exclusion criteria for unrelated donors: 16 suffered from well-controlled cardiovascular diseases (CVD) and 11 from allergic diathesis. Most of the selected donors with pre-existing disorders were candidates for apheresis HPC collection (21, 77.8%), while only six (22.2%) underwent BM harvest. We then analyzed the data relative to the corresponding 233 allogeneic HSCT to explore if the presence of pre-existing diseases in the donors could show any association with transplant characteristics. Transplants from CVD and allergy donors showed no significant disparities in comparison with those from healthy donors. A significant difference emerged regarding the disease severity, with a higher proportion of patients with high/very high disease risk index (DRI) among those receiving grafts from CVD donors (68.7% in transplants from CVD donors versus 36.0% in transplants from healthy donors, p=0.005). Multivariate analysis confirmed that high/very high DRI patients had an increased probability of receiving donations from CVD donors (OR, 4.89; 95%CI, 1.15-20.86; p=0.031). Among donors with well-controlled pre-existing conditions, no adverse events were recorded during stem cell collection or at follow-up. Our results suggest that in patients at high risk for relapse requiring a prompt allogeneic transplant, a familiar donor might be accepted for HPC apheresis donation on less strict criteria than unrelated donors, without risk for both donor and patient.

Abstract
BACKGROUND There is wide variation in stress test utilization before major vascular surgery and adherence to practice guidelines is unclear. We defined rates of stress test compliance at our institution and led a quality improvement initiative to improve compliance with American Heart Association (ACC/AHA) guidelines. METHODS We implemented a stress testing order set in the electronic medical record at one tertiary hospital. We reviewed all patients who underwent elective, major vascular surgery in the 6 months before (Jan 1, 2022 - Jul 1, 2022) and 6 months after (Aug 1, 2022 - Jan 31, 2023) implementation. We studied stress test guideline compliance, changes in medical or surgical management, and major adverse cardiac events (MACE). RESULTS Before order set implementation, 37/122 patients (30%) underwent stress testing within the past year (29 specifically ordered preoperatively) with 66% (19/29) guideline compliance. After order set implementation, 50/173 patients (29%) underwent stress testing within the past year (41 specifically ordered preoperatively) with 80% (33/41) guideline compliance. In the pre- and postimplementation cohorts, stress testing led to a cardiovascular medication change or preoperative coronary revascularization in 24% (7/29) and 27% (11/41) of patients, and a staged surgery or less invasive anesthetic strategy in 14% (4/29) and 4.9% (2/41) of patients, respectively. All unindicated stress tests were surgeon-ordered and none led to a change in management. There was no change in MACE after order set implementation. CONCLUSIONS Electronic medical record-based guidance of perioperative stress testing led to a slight decrease in overall stress testing and an increase in guideline-compliant testing. Our study highlights a need for improved preoperative cardiovascular risk assessment prior to major vascular surgery, which may eliminate unnecessary testing and more effectively guide perioperative decision-making.

Abstract
Artificial intelligence (AI) is a speciality within computer science that deals with creating systems that can replicate the intelligence of a human mind and has problem-solving abilities. AI includes a diverse array of techniques and approaches such as machine learning, neural networks, natural language processing, robotics, and expert systems. An electronic literature search was conducted using the databases of "PubMed" and "Google Scholar". The period for the search was from 2000 to June 2023. The search terms included "artificial intelligence", "machine learning", "liver cancers", "liver tumors", "hepatectomy", "perioperative" and their synonyms in various combinations. The search also included all MeSH terms. The extracted articles were further reviewed in a step-wise manner for identification of relevant studies. A total of 148 articles were identified after the initial literature search. Initial review included screening of article titles for relevance and identifying duplicates. Finally, 65 articles were reviewed for this review article. The future of AI in liver cancer planning and management holds immense promise. AI-driven advancements will increasingly enable precise tumour detection, location, and characterisation through enhanced image analysis. ML algorithms will predict patient-specific treatment responses and complications, allowing for tailored therapies. Surgical robots and AI-guided procedures will enhance the precision of liver resections, reducing risks and improving outcomes. AI will also streamline patient monitoring, better hemodynamic management, enabling early detection of recurrence or complications. Moreover, AI will facilitate data-driven research, accelerating the development of novel treatments and therapies. Ultimately, AI's integration will revolutionise liver cancer care, offering personalised, efficient and effective solutions, improving patients' quality of life and survival rates.

Abstract
BACKGROUND Vascular surgery carries a high risk of post-operative cardiac complications. Recent studies have shown an association between asymptomatic left ventricular systolic dysfunction and increased risk of major adverse cardiovascular events (MACE). This systematic review aims to evaluate the prognostic value of left ventricular function as determined by left ventricular ejection fraction (LVEF) measured by resting echocardiography before vascular surgery. METHODS This review conformed to PRISMA and MOOSE guidelines. PubMed, OVID Medline and Cochrane databases were searched from inception to 27 October 2022. Eligible studies assessed vascular surgery patients, with multivariable-adjusted or propensity-matched observational studies measuring LVEF via resting echocardiography and providing risk estimates for outcomes. The primary outcomes measures were all-cause mortality and congestive heart failure at 30 days. Secondary outcome included the composite outcome MACE. RESULTS Ten observational studies were included (4872 vascular surgery patients). Studies varied widely in degree of left ventricular systolic dysfunction, symptom status, and outcome reporting, precluding reliable meta-analysis. Available data demonstrated a trend towards increased incidence of all-cause mortality, congestive heart failure and MACE in patients with pre-operative LVEF <50%. Methodological quality of the included studies was found to be of moderate quality according to the Newcastle Ottawa Checklist. CONCLUSION The evidence surrounding the prognostic value of LVEF measurement before vascular surgery is currently weak and inconclusive. Larger scale, prospective studies are required to further refine cardiac risk prediction before vascular surgery.

Perioperative hyperoxia- impact on myocardial biomarkers, strain and outcome in high-risk patients undergoing non-cardiac surgery: Protocol for a prospective randomized controlled trial. Contemp Clin Trials 2024; 140:107512. [PMID: 38537904 DOI: 10.1016/j.cct.2024.107512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 02/21/2024] [Accepted: 03/24/2024] [Indexed: 04/05/2024]
Abstract
BACKGROUND Supplemental oxygen is used during every general anesthesia. However, for the maintenance phase of a general anesthesia, in most cases the longest part of anesthesia, only scarce evidence of dosing supplemental oxygen exists. Oxygen is a well-known coronary vasoconstrictor and thus may contribute to cardiovascular complications especially in vulnerable high-risk patients with coronary artery disease undergoing major non-cardiac surgery. Myocardial biomarkers are early indicators of myocardial injury. Oxygen supply demand mismatches due to coronary artery disease aggravated by hyperoxia might be displayed by changes from the biomarker's baseline-values. This study is designed to detect changes in myocardial biomarkers levels associated with perioperative hyperoxia. METHODS This prospective randomized controlled interventional trial investigates the impact of maintaining perioperative high oxygen supplementation in high-risk patients undergoing non-cardiac vascular surgery on cardiac biomarkers, myocardial strain and outcome in 110 patients. Patients are allocated to be supplemented with either 0.3 (normal) or 0.8 (high) fraction of inspired oxygen (FiO2) perioperatively. Included is a short crossover phase during which transesophageal echocardiography is used to evaluate myocardial function at FiO2 0.3 and 0.8 by strain analysis in each patient. Patients will be followed up for complications at 30 days and 1 year. CONCLUSION The trial is designed to evaluate perioperative changes from baseline myocardial biomarkers associated with perioperative FiO2. Furthermore, exploration and correlation of changes in biomarkers, acute early changes in myocardial function and clinical outcomes induced by different FiO2 may be possible.

Abstract
BACKGROUND In the BEST-CLI trial (Best Endovascular Versus Best Surgical Therapy for Patients With Chronic Limb-Threatening Ischemia), a prespecified secondary objective was to assess the effects of revascularization strategy on health-related quality of life (HRQoL). METHODS Patients with chronic limb-threatening ischemia were randomized to surgical bypass (Bypass) or endovascular intervention (Endo) in 2 parallel trials. Cohort 1 included patients with single-segment great saphenous vein; cohort 2 included those lacking suitable single-segment great saphenous vein. HRQoL was assessed over the trial duration using Vascular Quality-of-Life (VascuQoL), European Quality-of-Life-5D (EQ-5D), the Short Form-12 (SF-12) Physical Component Summary (SF-12 PCS), SF-12 Mental Component Summary (SF-12 MCS), Utility Index Score (SF-6D R2), and numeric rating scales of pain. HRQoL was summarized by cohort and compared within and between groups using mixed-model linear regression. RESULTS A total of 1193 and 335 patients in cohorts 1 and 2 with a mean follow-up of 2.9 and 2.0 years, respectively, were analyzed. In cohort 1, HRQoL significantly improved from baseline to follow-up for both groups across all measures. For example, mean (SD) VascuQoL scores were 3.0 (1.3) and 3.0 (1.2) for Bypass and Endo at baseline and 4.7 (1.4) and 4.8 (1.5) over follow-up. There were significant group differences favoring Endo when assessed with VascuQoL (difference, -0.14 [95% CI, -0.25 to -0.02]; P=0.02), SF-12 MCS (difference, -1.03 [95% CI, -1.89 to -0.18]; P=0.02), SF-6D R2 (difference, -0.01 [95% CI, -0.02 to -0.001]; P=0.03), numeric rating scale pain at present (difference, 0.26 [95% CI, 0.03 to 0.49]; P=0.03), usual level during previous week (difference, 0.26 [95% CI, 0.04 to 0.48]; P=0.02), and worst level during previous week (difference, 0.29 [95% CI, 0.02 to 0.56]; P=0.04). There was no difference between treatment arms on the basis of EQ-5D (difference, -0.01 [95% CI, -0.03 to 0.004]; P=0.12) or SF-12 PCS (difference, -0.41 [95% CI, -1.2 to 0.37]; P=0.31). In cohort 2, HRQoL also significantly improved from baseline to the end of follow-up for both groups based on all measures, but there were no differences between Bypass and Endo on any measure. CONCLUSIONS Among patients with chronic limb-threatening ischemia deemed eligible for either Bypass or Endo, revascularization resulted in significant and clinically meaningful improvements in HRQoL. In patients with an available single-segment great saphenous vein for bypass, but not among those without one, Endo was statistically superior on some HRQoL measures; however, these differences were below the threshold of clinically meaningful difference.

Abstract
PURPOSE Hypotension is common during anesthesia induction. However, minimal hemodynamic effects of remimazolam anesthesia have been reported. We hypothesized that remimazolam would have weaker hemodynamic effects than would propofol. To test this, we simultaneously evaluated the hemodynamics using the estimated continuous cardiac output (esCCO) system and heart rate variability (HRV) during anesthesia induction. METHODS This was a single-center, observational, retrospective study of patients undergoing dental surgery under general anesthesia between 2020 and 2022. Seventy patients were divided into two groups: remimazolam (R group; n=34) and propofol (P group; n=36). The information obtained from the anesthesia records, patient information, esCCO system parameters, and HRV were integrated and analyzed. The percentages of various parameters were set to 100% for the pre-induction phase as the baseline. RESULTS The %MAP (noninvasive mean arterial blood pressure) decreased over a narrower range in the R compared to the P group (-17.8% (-26.3%, -11.9%) vs. -22.6% (-32.9%, -17.0%); P=0.039). The %HR (heart rate) increased significantly in the R group and decreased in the P group (+10.7% (+6.5%, +18.6%) vs. -6.5% (-14.5%, +8.4%); P<0.01). The %SVesCCO (stroke volume calculated using the esCCO system) decreased significantly in both groups, but the R group showed a smaller difference compared to the P group (- 5.1% (-7.7%, -2.1%) vs. -10.0% (-13.8%, -5.6%); P<0.01). The rates of change in %LF nu (normalized unit of low frequency) and %HF nu (normalized unit of high frequency) were lower for the R than for the P group, although the difference was not significant (+6.8% (-14.5%, 32.4%) vs. +9.2% (-7.2%, +59.7%), P=0.30; +7.9% (-51.0%, +66.9%) vs. +22.8% (-26.1%, +61.6%), P=0.57). CONCLUSION Remimazolam demonstrated a lower MAP reduction rate than propofol. A compensatory increase in HR occurred with a decrease in stroke volume. However, the HR increase was not attributable to the autonomic nervous system.

Abstract
BACKGROUND Temporal trends and risk factors of perioperative cardiac events (PCEs) in patients over 80 years old with coronary artery disease (CAD) undergoing noncardiac surgery are still unclear. METHODS We retrospectively reviewed 1478 patients over 80 years old, with known CAD undergoing selective noncardiac surgery in a single center (2014-2022). Patients were divided into three equal time groups based on the discharge date (2014-2016, 2017-2019, and 2020-2022), with 367, 473, and 638 patients in Groups 1-3, respectively. Perioperative clinical variables were extracted from the electronic medical records database. The primary outcome was the occurrence of PCEs intraoperatively or during hospitalization postoperatively, defined as any of the following events: myocardial infarction, heart failure, nonfatal cardiac arrest, and death. RESULTS PCEs occurred in 180 (12.2%) patients. Eight independent risk factors were associated with PCEs, including four clinical factors (body mass index < 22 kg/m2, history of myocardial infarction, history of heart failure, and general anesthesia) and four preoperative laboratory results (hemoglobin < 110 g/L, albumin < 40 g/L, creatinine > 120 μmol/L, and potassium <3.6 mmol/L). Significant rising trends were seen over the 9-year study period in the incidence of PCEs and independent risk factors including history of myocardial infarction, history of heart failure, general anesthesia, preoperative hemoglobin < 110 g/L, preoperative albumin < 40 g/L, and preoperative creatinine > 120 μmol/L (P for trend <0.05). CONCLUSION The incidence and independent risk factors of PCEs in patients over 80 years old with CAD undergoing noncardiac surgery showed significant rising trends over the last 9-year period.

Rostagno C, Craighero A. Postoperative Myocardial Infarction after Non-Cardiac Surgery: An Update. J Clin Med 2024; 13:1473. [PMID: 38592265 PMCID: PMC10932291 DOI: 10.3390/jcm13051473] [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: 01/23/2024] [Revised: 02/29/2024] [Accepted: 03/01/2024] [Indexed: 04/10/2024] Open
Abstract
Every year, not less than 300 million non-cardiac surgery interventions are performed in the world. Perioperative mortality after non-cardiac surgery is estimated at 2% in patients over 45 years of age. Cardiovascular events account for half of these deaths, and most are due to perioperative myocardial infarction (MINS). The diagnosis of postoperative myocardial infarction, before the introduction of cardiac biomarkers, was based on symptoms and electrocardiographic changes and its incidence was largely underestimated. The incidence of MINS when a standard troponin assay is used ranges between 8 and 19% but increases to 20-30% with high-sensitivity troponin assays. Higher troponin values suggesting myocardial injury, both with or without a definite diagnosis of myocardial infarction, are associated with an increase in 30-day and 1-year mortality. Diagnostic and therapeutic strategies are reported.

Neurosurgery 2024; 94:597-605. [PMID: 37800926 DOI: 10.1227/neu.0000000000002710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 08/10/2023] [Indexed: 10/07/2023] Open
Abstract
BACKGROUND AND OBJECTIVE Perioperative low-dose aspirin (ASA) management for open craniotomy surgery lacked information. We analyze to establish the perioperative ASA strategy to minimize both hemorrhagic and thromboembolic complications. METHODS The investigators designed a multicenter retrospective study, which included patients scheduled to have clipping surgery for unruptured intracranial aneurysm. The incidence and risk factors were analyzed for postoperative hemorrhagic complications and major cardio- and cerebrovascular events (MACCEs) within 1 month postoperation. RESULTS This study included 503 long-term ASA users of 3654 patients at three tertiary centers. The incidence of hemorrhagic complications and MACCEs was 7.4% (37/503) and 8.8% (44/503), respectively. Older age (>70 years, odds ratio [OR]: 2.928, 95% CI [1.337-6.416]), multiple aneurysms operation (OR: 2.201, 95% CI [1.017-4.765]), large aneurysm (>10 mm, OR: 4.483, 95% CI [1.485-13.533]), and ASA continuation (OR: 2.604, 95% CI [1.222-5.545]) were independent risk factors for postoperative hemorrhagic complications. Intracranial hemorrhage was the only type of hemorrhagic complication that increased in the ASA continuation group (10.6% vs 2.9%, P = .001). Between the ASA continuation and discontinuation groups, the overall incidence of MACCEs was not significantly different (log-rank P = .8). In the subgroup analysis, ASA discontinuation significantly increased the risk of MACCEs in the secondary prevention group (adjusted hazard ratio: 2.580, 95% CI [1.015-6.580]). CONCLUSION ASA continuation increased the risk of postoperative intracranial hemorrhage. Simultaneously, ASA discontinuation was the major risk factor for postoperative MACCEs in the high-risk group. Without evidence of intracranial hemorrhage, early ASA resumption was indicated (a total cessation duration <7-10 days) in the secondary prevention group.

Abstract
More than 300 million surgeries are performed annually worldwide. Patients are progressively aging and often have multiple comorbidities that put them at increased cardiovascular risk in the perioperative period. The United States published latest guidelines regarding preoperative cardiac evaluation and risk stratification for patients undergoing non-cardiac surgery in 2014. There are multiple risk stratification tools available that can help guide management. Furthermore, newer laboratory tests, such as preoperative NT-proBNP and high-sensitivity troponin assays, may aid in preventing and diagnosing perioperative myocardial injury.

Perioperative copeptin: predictive value and risk stratification in patients undergoing major noncardiac surgery-a prospective observational cohort study. Can J Anaesth 2024; 71:330-342. [PMID: 38243094 PMCID: PMC10923994 DOI: 10.1007/s12630-023-02677-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 09/18/2023] [Accepted: 09/18/2023] [Indexed: 01/21/2024] Open
Abstract
PURPOSE Biomarkers can aid in perioperative risk stratification. While preoperative copeptin has been associated with adverse events, intraoperative information is lacking and this association may rather reflect a baseline risk. Knowledge about correlations between postoperative copeptin measurements and clinically relevant outcomes is scarce. We examined the association of perioperative copeptin concentrations with postoperative all-cause mortality and/or major adverse cardiac and cerebrovascular events (MACCE) at 12 months and 30 days as well as with perioperative myocardial injury (PMI). METHODS We conducted a prospective observational cohort study of adults undergoing noncardiac surgery with intermediate to high surgical risk in Basel, Switzerland, and Düsseldorf, Germany from February 2016 to December 2020. We measured copeptin and cardiac troponin before surgery, immediately after surgery (0 hr) and once between the second and fourth postoperative day (POD 2-4). RESULTS A primary outcome event of a composite of all-cause mortality and/or MACCE at 12 months occurred in 48/502 patients (9.6%). Elevated preoperative copeptin (> 14 pmol·L-1), immediate postoperative copeptin (> 90 pmol·L-1), and copeptin on POD 2-4 (> 14 pmol·L-1) were associated with lower one-year MACCE-free and/or mortality-free survival (hazard ratio [HR], 2.89; 95% confidence interval [CI], 1.62 to 5.2; HR, 2.07; 95% CI, 1.17 to 3.66; and HR, 2.47; 95% CI, 1.36 to 4.46, respectively). Multivariable analysis continued to show an association for preoperative and postoperative copeptin on POD 2-4. Furthermore, elevated copeptin on POD 2-4 showed an association with 30-day MACCE-free survival (HR, 2.15; 95% CI, 1.18 to 3.91). A total of 64 of 489 patients showed PMI (13.1%). Elevated preoperative copeptin was not associated with PMI, while immediate postoperative copeptin was modestly associated with PMI. CONCLUSION The results of the present prospective observational cohort study suggest that perioperative copeptin concentrations can help identify patients at risk for all-cause mortality and/or MACCE. Other identified risk factors were revised cardiac risk index, body mass index, surgical risk, and preoperative hemoglobin. TRIAL REGISTRATION ClinicalTrials.gov (NCT02687776); first submitted 9 February 2016.

Abstract
PURPOSE The preoperative management guidelines of surgical patients are constantly evolving as newer evidence-based research is published. Oral and maxillofacial surgeons need to be current with the increasingly more complex new drug therapies and updated national association(s) guidelines. This narrative review provides a synopsis with important reference tables for updated preoperative optimization guidelines for anticoagulation, antiplatelet therapy, antihypertensive management, and glycemic control in the preoperative period for the oral and maxillofacial surgery patient. It also includes the most current anesthesia guidelines on glucagon-like peptide receptor agonists. METHODS The search strategy utilized pubmed.gov to identify the most recent national society guidelines and review articles pertinent to perioperative anticoagulation, antiplatelet therapy, antihypertensive management, and glycemic control. RESULTS The search identified 75 articles from the American College of Surgeons, American Heart Association, American Society of Anesthesiologists, American College of Cardiologists, in addition to recent reviews discussing the standard of care for optimization of patients in the perioperative period. CONCLUSION Medical optimization prior to surgery is important for safe and efficient surgical practice and has been shown to improve overall mortality. This narrative review provides a summary of the current data with recommendations focusing on four key points.

Abstract
BACKGROUND We aimed to determine the relationship between common preoperative comorbidities and subsequent incidence of postoperative surgical site infections (SSIs) in hand and finger fractures and/or dislocations. METHODS We queried the American College of Surgeons National Safety and Quality Improvement Program from January 1, 2015 to December 31, 2019. Patients were included in our study if they were treated by open or percutaneous fixation for any hand or finger fracture and/or dislocation. Predictor variables were smoking status, diabetes mellitus status, and obesity (body mass index > 30) status. Primary outcome was incidence of postoperative SSI. RESULTS There were a total of 9245 patients included in our study, and 148 patients (1.6%) experienced postoperative SSI. Of these, 59 patients (39.9%) were only smokers, 7 patients (4.7%) only had diabetes mellitus, and 55 patients (37.2%) were only obese. Overall, patients experienced greater odds of sustaining a postoperative SSI if they were a smoker or diabetic compared to non-smokers and non-diabetics, respectively. Considering only open fixation modality, patients with comorbidities were not at significantly increased odds of sustaining postoperative SSI. Considering only percutaneous fixation modality, patients experienced significantly greater odds of sustaining postoperative SSI if they were a smoker compared to non-smoker. CONCLUSIONS Common preoperative comorbidities, including smoking status and diabetes mellitus, increase the likelihood of postoperative complication in patients with hand and finger fractures and/or dislocations undergoing surgical treatment. Further investigation into the different relationship of these comorbidities between open and closed fractures with larger sample sizes will be valuable.

Abstract
Ophthalmic surgery encompasses a wide range of procedures addressing various ocular conditions. Although generally considered low risk, a thorough preoperative evaluation is still crucial in optimizing patient outcomes and ensuring safe surgical interventions. This review provides a comprehensive overview of the preoperative assessment and management of patients presenting for ophthalmic surgery, specifically focusing on cataract surgery. We discuss the role of routine preoperative testing, the assessment of intraocular factors, and the evaluation of systemic comorbidities and medications. The review emphasizes the importance of individualized decision-making based on patient-specific factors and collaborative efforts between ophthalmologists and the health-care team.

Abstract
Esophagectomy is an exemplar of complex oncological surgery and is associated with a relatively high risk of major morbidity and mortality. In the modern era, where specific complications are targeted in prevention and treatment pathways, and where the principles of enhanced recovery after surgery are espoused, optimum outcomes are targeted via a number of approaches. These include comprehensive clinical and physiological risk assessment, specialist perioperative care by a high-volume team, and multimodal inputs throughout the patient journey that aim to preserve or restore nutritional deficits, muscle mass and function.

Abstract
PURPOSE Perioperative management of patients medicated with antithrombotics requiring elective intracranial procedures is challenging. We ought to (1) identify the clinical practice guidelines (CPGs) and recommendations (CPRs) on perioperative management of antithrombotic agents in elective intracranial surgery and (2) assess their methodological quality and reporting clarity. METHODS The study was conducted following the 2020 PRISMA guidelines for a systematic review and has been registered (PROSPERO, CRD42023415710). An electronic search was conducted using PubMed, Scopus, and Google Scholar. The search terms used were "adults," "antiplatelets," "anticoagulants," "guidelines," "recommendations," "english language," "cranial surgery," "brain surgery," "risk of bleeding," "risk of coagulation," and "perioperative management" in all possible combinations. The search period extended from 1964 to April 2023 and was limited to literature published in the English language. The eligible studies were evaluated by three blinded raters, by employing the Appraisal of Guidelines for Research & Evaluation II (AGREE-II) analysis tool. RESULTS A total of 14 sets of guidelines were evaluated. Two guidelines from the European Society of Anaesthesiology and one from the American College of Chest Physicians found to have the highest methodological quality and reporting clarity according to the AGREE-II tool. The interrater agreement was good with a mean Cohens Kappa of 0.70 (range, 46.5-94.4%) in the current analysis. CONCLUSION The perioperative management of antithrombotics in intracranial procedures may be challenging, complex, and demanding. Due to the lack of high quality data, uncertainty remains regarding the optimal practices to balance the risk of thromboembolism against that of bleeding.

Abstract
INTRODUCTION Abdominal oncologic surgeries pose significant risks due to the complexity of the surgery and patients' often weakened health, multiple comorbidities, and increased perioperative hazards. Hypotension is a major risk factor for perioperative cardiovascular complications, necessitating individualized management in modern anesthesiology. AIM This study aimed to determine the dynamics of changes in troponin and NTproBNP levels during the first two postoperative days in patients undergoing major cancer abdominal surgery with advanced hemodynamic monitoring including The AcumenTM Hypotension Prediction Index software (HPI) (Edwards Lifesciences, Irvine, CA, USA) and their association with the occurrence of postoperative cardiovascular complications. METHODS A prospective study was conducted, including 50 patients scheduled for abdominal cancer surgery who, due to the overall risk of perioperative complications (ASA class 3 or 4), were monitored using the HPI software. Hypotension was qualified as at least one ≥ 1 min episode of a MAP < 65 mm Hg. Preoperatively and 24 and 48 h after the procedure, the levels of NTproBNP and troponin were measured, and an ECG was performed. RESULTS We analyzed data from 46 patients and found that 82% experienced at least one episode of low blood pressure (MAP < 65 mmHg). However, the quality indices of hypotension were low, with a median time-weighted average MAP < 65 mmHg of 0.085 (0.03-0.19) mmHg and a median of 2 (2-1.17) minutes spent below MAP < 65 mmHg. Although the incidence of perioperative myocardial injury was 10%, there was no evidence to suggest a relationship with hypotension. Acute kidney injury was seen in 23.9% of patients, and it was significantly associated with a number of episodes of MAP < 50 mmHg. Levels of NTproBNP were significantly higher on the first postoperative day compared to preoperative values (285.8 [IQR: 679.8] vs. 183.9 [IQR: 428.1] pg/mL, p < 0.001). However, they decreased on the second day (276.65 [IQR: 609.4] pg/mL, p = 0.154). The dynamics of NTproBNP were similar for patients with and without heart failure, although those with heart failure had significantly higher preoperative concentrations (435.9 [IQR: 711.15] vs. 87 [IQR: 232.2] pg/mL, p < 0.001). Patients undergoing laparoscopic surgery showed a statistically significant increase in NTproBNP. CONCLUSIONS This study suggests that advanced HPI monitoring in abdominal cancer surgery effectively minimizes intraoperative hypotension with no significant NTproBNP or troponin perioperative dynamics, irrespective of preoperative heart failure.

Abstract
Cardiovascular complications in patients undergoing thoracic surgery, which physicians have a limited ability to predict, are often unavoidable and resulting in adverse outcome. Cardiopulmonary exercise testing (CPET), the gold standard of cardiopulmonary function evaluation, has also been proved to be a preoperative risk assessment tool. Meanwhile, elevated red blood cell distribution width (RDW) has surged as a biochemical marker in the occurrence of cardiovascular disease. However, it is yet unclear the value of CPET combined with RDW in predicting cardiovascular complications after thoracic surgery. 50 patients with cardiovascular complications after thoracic surgery were collected as the case group, and 100 thoracic surgery patients were recruited as the control group, with the same gender, age ± 2 years old, and no postoperative complications. After admission, all patients underwent CPET and RDW inspection before surgery, and the results were recorded. The CPET parameter oxygen pulse (VO2/HR) and RDW of the case group were lower than those of the control group (P < 0.05), and the ventilation/carbon dioxide production (VE/VCO2 slope) was significantly higher than control group (P < 0.01). The biochemical parameters hemoglobin (Hb) and Glomerular filtration rate (GFR)) of the case group were lower than those of the control group (P < 0.05), the homocysteine (hCY), creatinine (Cr), operation time and blood loss of the case group were higher than those of the control group (P < 0.05). The RDW had a negative correlation with VO2 max in both overall and control group. The combination of VO2/kg and RDW had the highest diagnostic value in predicting cardiovascular complications. The combination of VO2/kg and RDW has predictive diagnostic value and is more suitable for predicting postoperative complications of thoracic surgery.

Abstract
BACKGROUND The National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator from the American College of Surgeons is a widely available tool for peri-operative risk prediction. This study investigates its predictive performance in an Australian setting. METHODS A single-centre retrospective external validation study was conducted at a tertiary referral centre in New South Wales, Australia. Data from a general surgical cohort in a 2-year period from 2020 to 2021 was collected from the NSQIP database and entered into the NSQIP calculator. The predictive performance of the calculator was analysed across the standard 14 NSQIP postoperative outcome measures at 30 days. RESULTS There were 2121 patient records analysed using tests of accuracy and in the discrimination and calibration domains. The overall predictive performance of the NSQIP calculator was reasonable. There was greater accuracy at lower-risk predictions. At higher-risk predictions, Readmission, Death, and Discharge to Nursing or Rehab Facility, and Length of Stay were overestimated, whilst other outcomes were underestimated. CONCLUSION This study demonstrates reasonable overall performance of the NSQIP calculator in the context of this cohort and provides data to support the need for locally adapted and validated risk prediction tools for use by Australian perioperative physicians.

Abstract
AIMS To leverage deep learning on the resting 12-lead electrocardiogram (ECG) to estimate peak oxygen consumption (V˙O2peak) without cardiopulmonary exercise testing (CPET). METHODS AND RESULTS V ˙ O 2 peak estimation models were developed in 1891 individuals undergoing CPET at Massachusetts General Hospital (age 45 ± 19 years, 38% female) and validated in a separate test set (MGH Test, n = 448) and external sample (BWH Test, n = 1076). Three penalized linear models were compared: (i) age, sex, and body mass index ('Basic'), (ii) Basic plus standard ECG measurements ('Basic + ECG Parameters'), and (iii) basic plus 320 deep learning-derived ECG variables instead of ECG measurements ('Deep ECG-V˙O2'). Associations between estimated V˙O2peak and incident disease were assessed using proportional hazards models within 84 718 primary care patients without CPET. Inference ECGs preceded CPET by 7 days (median, interquartile range 27-0 days). Among models, Deep ECG-V˙O2 was most accurate in MGH Test [r = 0.845, 95% confidence interval (CI) 0.817-0.870; mean absolute error (MAE) 5.84, 95% CI 5.39-6.29] and BWH Test (r = 0.552, 95% CI 0.509-0.592, MAE 6.49, 95% CI 6.21-6.67). Deep ECG-V˙O2 also outperformed the Wasserman, Jones, and FRIEND reference equations (P < 0.01 for comparisons of correlation). Performance was higher in BWH Test when individuals with heart failure (HF) were excluded (r = 0.628, 95% CI 0.567-0.682; MAE 5.97, 95% CI 5.57-6.37). Deep ECG-V˙O2 estimated V˙O2peak <14 mL/kg/min was associated with increased risks of incident atrial fibrillation [hazard ratio 1.36 (95% CI 1.21-1.54)], myocardial infarction [1.21 (1.02-1.45)], HF [1.67 (1.49-1.88)], and death [1.84 (1.68-2.03)]. CONCLUSION Deep learning-enabled analysis of the resting 12-lead ECG can estimate exercise capacity (V˙O2peak) at scale to enable efficient cardiovascular risk stratification.

Abstract
OBJECTIVE To understand the consequences of functional cardiac stress testing among patients considering noncardiac nonophthalmologic surgery. DESIGN A retrospective cohort study of 118,552 patients who made 159,795 visits to a dedicated preoperative risk assessment and optimization clinic between 2008 and 2018. SETTING A large integrated health system. PATIENTS Patients who visited a dedicated preoperative risk assessment and optimization clinic before noncardiac nonophthalmologic surgery. MEASUREMENTS To assess changes to care delivered, we measured the probability of completing additional cardiac testing, cardiac surgery, or noncardiac surgery. To assess outcomes, we measured time-to-mortality and total one-year mortality. MAIN RESULTS In causal inference models, preoperative stress testing was associated with increased likelihood of coronary angiography (relative risk: 8.6, 95% CI 6.1-12.1), increased likelihood of percutaneous coronary intervention (RR: 4.1, 95% CI: 1.8-9.2), increased likelihood of cardiac surgery (RR: 6.8, 95% CI 4.9-9.4), decreased likelihood of noncardiac surgery (RR: 0.77, 95% CI 0.75-0.79), and delayed noncardiac surgery for patients completing noncardiac surgery (mean 28.3 days, 95% CI: 23.1-33.6). The base rate of downstream cardiac testing was low, and absolute risk increases were small. Stress testing was associated with higher mortality in unadjusted analysis but was not associated with mortality in causal inference analyses. CONCLUSIONS Preoperative cardiac stress testing likely induces coronary angiography and cardiac interventions while decreasing use of noncardiac surgery and delaying surgery for patients who ultimately proceed to noncardiac surgery. Despite changes to processes of care, our results do not support a causal relationship between stress testing and postoperative mortality. Analyses of care cascades should consider care that is avoided or substituted in addition to care that is induced.

Abstract
OBJECTIVE To assess the incremental contribution of preoperative stress test results toward a diagnosis of obstructive coronary artery disease (CAD), prediction of mortality, or prediction of perioperative myocardial infarction in patients considering noncardiac, nonophthalmologic surgery. DESIGN, SETTING, PARTICIPANTS A retrospective cohort study of visits to a preoperative risk assessment and optimization clinic in a large health system between 2008 and 2018. MEASUREMENTS To assess diagnostic information of preoperative stress testing, we used the Begg and Greenes method to calculate test characteristics adjusted for referral bias, with a gold standard of angiography. To assess prognostic information, we first created multiply-imputed logistic regression models to predict 90-day mortality and perioperative myocardial infarction (MI), starting with two tools commonly used to assess perioperative cardiac risk, Revised Cardiac Risk Index (RCRI) and Myocardial Infarction or Cardiac Arrest (MICA). We then added stress test results and compared the discrimination for models with and without stress test results. MAIN RESULTS Among 136,935 visits by patients without an existing diagnosis of CAD, the decision to obtain preoperative stress testing identified around 4.0% of likely new diagnoses. Stress testing increased the likelihood of CAD (likelihood ratio: 1.31), but for over 99% of patients, stress testing should not change a decision on whether to proceed to angiography. In 117,445 visits with subsequent noncardiac surgery, stress test results failed to improve predictions of either perioperative MI or 90-day mortality. Reweighting the models and adding hemoglobin improved the prediction of both outcomes. CONCLUSIONS Cardiac stress testing before noncardiac, nonophthalmologic surgery does not improve predictions of either perioperative mortality or myocardial infarction. Very few patients considering noncardiac, nonophthalmologic surgery have a pretest probability of CAD in a range where stress testing could usefully select patients for angiography. Better use of existing patient data could improve predictions of perioperative adverse events without additional patient testing.

Abstract
OBJECTIVE Many patients undergoing thoracoabdominal aortic aneurysm (TAAA) repair have had a previous myocardial infarction (MI). To address the paucity of data regarding outcomes in such patients, we aimed to compare outcomes after open TAAA repair in patients with and without previous MI. METHODS From 1986 to 2022, we performed 3737 consecutive open TAAA repairs. Of these, 706 (18.9%) were in patients with previous MI. We used multivariable logistic regression to identify predictors of operative death. Propensity score matching analyzed preoperative and select operative variables to create matched groups of patients with or without a previous MI (n = 704 pairs). Late survival was determined by Kaplan-Meier analysis and compared by log rank test. RESULTS Overall, operative mortality was 8.5% and the adverse event rate was 15.2%; these were elevated in patients with MI (11.0% vs 7.9% [P = .01] and 18.0% vs 14.6% [P = .02], respectively). In the propensity score-matching cohort, the MI group had a greater rate of cardiac complications (32.4% vs 25.4%; P = .005) and delayed paraparesis (5.1% vs 2.4%; P = .1); however, there was no difference in operative mortality (11.1% vs 10.9%; P = 1) or adverse event rate (18.0% vs 16.8%; P = .6). Overall, previous MI was not independently associated with operative mortality in multivariable analysis (P = .1). The matched MI group trended toward poorer 10-year survival (29.8% ± 1.9% non-MI vs 25.0% ± 1.8% MI; P = .051). CONCLUSIONS Although previous MI was not associated with early mortality after TAAA repair, patients with a previous MI had greater rates of cardiac complications and delayed paraparesis. Patients with a previous MI also trended toward poorer survival.

Abstract
Extensive preventive strategies in the perioperative period are popular worldwide. Novel "prehabilitation" approaches are being defined for every individual surgical discipline. With intention to reduce perioperative morbidity, "prehabilitation" was developed to increase "physical wellness" considering exercise capacity, nutritional status, and psychological support. Thus, prehabilitation could be well-suited for patients undergoing lung cancer surgery. Theoretically, improving physical condition may increase the chances of having a better post-operative course, especially among frail patients. In this review, we describe the concept of prehabilitation with possible benefits, its role in the Enhanced Recovery After Surgery protocols, and its potential for the future.

Preventing quality improvement drift: evaluation of efforts to sustain the cost savings from implementing best practice guidelines to reduce unnecessary electrocardiograms (ECGs) during the preadmisison testing evaluation. J Osteopath Med 2023; 123:547-554. [PMID: 37532683 DOI: 10.1515/jom-2022-0196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Accepted: 07/11/2023] [Indexed: 08/04/2023]
Abstract
CONTEXT Medical professionals commonly fail to follow best practice guidelines. Drift, or a return to previous tendencies, is abundant in healthcare even when guidelines are followed initially. This "drift" was found internally at Temple University Hospital with preoperative electrocardiograms (ECGs). Best-practice guidelines were instituted and followed as a first step, but sustaining performance improvement was the ultimate goal. OBJECTIVES The objectives are to improve and maintain adherence to published guidelines for preoperative ECG testing at Temple University Hospital in a physician-led, nurse practitioner (NP)-staffed preadmission testing (PAT) clinic. METHODS To start this quality improvement (QI) project, a retrospective chart review was completed to determine the number of ECGs performed in PAT at Temple University Hospital in 2017. New guidelines for ordering preoperative ECGs were then implemented, and Plan-Do-Study-Act (PDSA) cycles were performed over 3 years. A repeat retrospective chart review was completed and looked at ECGs ordered from 2018 through 2020. The number of ECGs completed in PAT before and after implementation of the new guidelines was then compared. In addition, the complexity of our surgical patients was estimated by looking at the yearly average American Society of Anesthesiology Physical Health Status (American Society of Anesthesiology [ASA] status) values assigned. Finally, the cost of performing each ECG was calculated, and the cost savings to the hospital over 4 years was determined. RESULTS The baseline ECG rate for PAT in 2017, 2018, 2019, and 2020 at Temple University Hospital was 54.0 , 20.7, 22.3, and 21.9 %, respectively, which was a statistically significant decrease in ECG performance rate in the years after implementation of the PDSA project. The ASA status average remained constant, demonstrating that while patients' medical diagnoses remained on average the same, reinforced training had been effective in preventing a return to previous liberal ordering tendencies. Over the course of 4 years, the reduction in unnecessary ECGs led to an estimated direct cost savings of $213,000. CONCLUSIONS Self-adoption of best-practice guidelines among clinicians is often poor; however, the barriers to adoption can be overcome with education and individual feedback. Sustaining performance improvement gains is challenging, but possible, as shown by example in one urban, academic teaching hospital's physician-led, NP-staffed outpatient clinic.

BACKGROUND The optimal antiplatelet therapy (APT) for patients undergoing non-cardiac surgery within 1 year after percutaneous coronary intervention (PCI) is not yet established. METHODS Patients who underwent non-cardiac surgery within 1 year after second-generation drug-eluting stent implantation were included from a multicenter prospective registry in Korea. The primary endpoint was 30-day net adverse clinical event (NACE), including all-cause death, major adverse cardiovascular event (MACE), and major bleeding events. Covariate adjustment using propensity score was performed. RESULTS Among 1130 eligible patients, 708 (62.7%) continued APT during non-cardiac surgery. After propensity score adjustment, APT continuation was associated with a lower incidence of NACE (3.7% vs 5.5%; adjusted odds ratio [OR], 0.48; 95% confidence interval [CI], 0.26-0.89; P = .019) and MACE (1.1% vs 1.9%; adjusted OR, 0.35; 95% CI, 0.12-0.99; P = .046), whereas the incidence of major bleeding events was not different between the 2 APT strategies (1.7% vs 2.6%; adjusted OR, 0.61; 95% CI, 0.25-1.50; P = .273). CONCLUSIONS The APT continuation strategy was chosen in a substantial proportion of patients and was associated with the benefit of potentially reducing 30-day NACE and MACE with similar incidence of major bleeding events, compared with APT discontinuation. This study suggests a possible benefit of APT continuation in non-cardiac surgery within 1 year of second-generation drug-eluting stent implantation.

Neutrophilia is more predictive than increased white blood cell counts for short-term mortality after liver transplantation in patients with acute-on-chronic liver failure. Anesth Pain Med (Seoul) 2023; 18:389-396. [PMID: 37919923 PMCID: PMC10635859 DOI: 10.17085/apm.23048] [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: 04/17/2023] [Revised: 07/22/2023] [Accepted: 07/26/2023] [Indexed: 11/04/2023] Open
Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) is a life-threatening disease that requires urgent liver transplantation (LT). Accurate identification of high-risk patients is essential for predicting post-LT survival. The chronic liver failure consortium ACLF score is a widely accepted risk-stratification score that includes total white blood cell (WBC) counts as a component. This study aimed to evaluate the predictive value of total and differential WBC counts for short-term mortality following LT in patients with ACLF. METHODS A total of 685 patients with ACLF who underwent LT between January 2008 and February 2019 were analyzed. Total and differential WBC counts were examined as a function of the model for end-stage liver disease for sodium (MELD-Na) score. The association between total and differential WBC counts and 90-day post-LT mortality was assessed using multivariable Cox proportional hazards regression analysis. RESULTS The total WBC counts and neutrophil ratio were higher in patients with ACLF than in those without ACLF. The neutrophil ratio was significantly associated with 90-day post-LT mortality after adjustment (hazard ratio [HR], 1.04; P = 0.001), whereas total WBC counts were not significantly associated with 90-day post-LT mortality in either univariate or multivariate Cox analyses. The neutrophil ratio demonstrated a relatively linear trend with an increasing MELD-Na score and HR for 90-day post-LT mortality, whereas the total WBC counts exhibited a plateaued pattern. CONCLUSIONS Neutrophilia, rather than total WBC counts, is a better prognostic indicator for short-term post-LT mortality in patients with ACLF.

Abstract
Aerobic, or endurance, exercise is an energy requiring process supported primarily by energy from oxidative adenosine triphosphate synthesis. The consumption of oxygen and production of carbon dioxide in muscle cells are dynamically linked to oxygen uptake (V̇O2) and carbon dioxide output (V̇CO2) at the lung by integrated functions of cardiovascular, pulmonary, hematologic, and neurohumoral systems. Maximum oxygen uptake (V̇O2max) is the standard expression of aerobic capacity and a predictor of outcomes in diverse populations. While commonly limited in young fit individuals by the capacity to deliver oxygen to exercising muscle, (V̇O2max) may become limited by impairment within any of the multiple systems supporting cellular or atmospheric gas exchange. In the range of available power outputs, endurance exercise can be partitioned into different intensity domains representing distinct metabolic profiles and tolerances for sustained activity. Estimates of both V̇O2max and the lactate threshold, which marks the upper limit of moderate-intensity exercise, can be determined from measures of gas exchange from respired breath during whole-body exercise. Cardiopulmonary exercise testing (CPET) includes measurement of V̇O2 and V̇CO2 along with heart rate and other variables reflecting cardiac and pulmonary responses to exercise. Clinical CPET is conducted for persons with known medical conditions to quantify impairment, contribute to prognostic assessments, and help discriminate among proximal causes of symptoms or limitations for an individual. CPET is also conducted in persons without known disease as part of the diagnostic evaluation of unexplained symptoms. Although CPET quantifies a limited sample of the complex functions and interactions underlying exercise performance, both its specific and global findings are uniquely valuable. Some specific findings can aid in individualized diagnosis and treatment decisions. At the same time, CPET provides a holistic summary of an individual's exercise function, including effects not only of the primary diagnosis, but also of secondary and coexisting conditions.

Abstract
OBJECTIVE To measure the frequency of preoperative stress testing and its association with perioperative cardiac events. BACKGROUND There is persistent variation in preoperative stress testing across the United States. It remains unclear whether more testing is associated with reduced perioperative cardiac events. METHODS We used the Vizient Clinical Data Base to study patients who underwent 1 of 8 elective major surgical procedures (general, vascular, or oncologic) from 2015 to 2019. We grouped centers into quintiles by frequency of stress test use. We computed a modified revised cardiac risk index (mRCRI) score for included patients. Outcomes included in-hospital major adverse cardiac events (MACEs), myocardial infarction (MI), and cost, which we compared across quintiles of stress test use. RESULTS We identified 185,612 patients from 133 centers. The mean age was 61.7 (±14.2) years, 47.5% were female, and 79.4% were White. Stress testing was performed in 9.2% of patients undergoing surgery, and varied from 1.7% at lowest quintile centers, to 22.5% at highest quintile centers, despite similar mRCRI comorbidity scores (mRCRI>1: 15.0% vs 15.8%; P =0.068). In-hospital MACE was less frequent among lowest versus highest quintile centers (8.2% vs 9.4%; P <0.001) despite a 13-fold difference in stress test use. Event rates were similar for MI (0.5% vs 0.5%; P =0.737). Mean added cost for stress testing per 1000 patients who underwent surgery was $26,996 at lowest quintile centers versus $357,300 at highest quintile centers. CONCLUSIONS There is substantial variation in preoperative stress testing across the United States despite similar patient risk profiles. Increased testing was not associated with reduced perioperative MACE or MI. These data suggest that more selective stress testing may be an opportunity for cost savings through a reduction of unnecessary tests.

Sex-related differences in functional capacity and its implications in risk stratification before major non-cardiac surgery: a post hoc analysis of the international METS study. EClinicalMedicine 2023; 64:102223. [PMID: 37811489 PMCID: PMC10556582 DOI: 10.1016/j.eclinm.2023.102223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 08/24/2023] [Accepted: 09/05/2023] [Indexed: 10/10/2023] Open
Abstract
Background Poor functional capacity has been identified as an important modifiable risk factor for postoperative complications. Cardiopulmonary exercise testing (CPET) provides objective parameters of functional capacity (e.g., oxygen consumption at peak exercise, peak VO2), with significant prognostication for postoperative complications. However, sex-specific thresholds for functional capacity to predict surgical risk are yet to be established. Therefore, we performed a post hoc analysis of the international, multicentre, prospective observational METS (Measurement of Exercise Tolerance before Surgery) study to evaluate if sex-specific thresholds of peak VO2 improve risk prediction of postoperative complications. Methods We undertook a post hoc analysis (HREC/71824/PMCC) of the METS study, which was performed between March 2013 and March 2016. We investigated whether sex-specific differences exist for CPET-derived parameters and associated thresholds for predicting postoperative complications in this large cohort of patients that had major non-cardiac surgery (n = 1266). Logistic regression models were analyzed for the association of low peak VO2 with moderate-to-severe in-hospital postoperative complications. Optimal sex-specific peak VO2 thresholds were obtained by maximizing the Youden index of receiver operating characteristic (ROC) curves. Finally, multivariable logistic regression models tested the resulting sex-specific thresholds against the established non-sex-specific peak VO2 threshold (14 mL kg-1 min-1) adjusted for clinically relevant features such as comorbidities and surgical complexity. Models were evaluated by bootstrapping optimism-corrected area under the ROC curve and the net reclassification improvement index (NRI). Findings Female patients (n = 480) had a lower mean (SD) peak VO2 than males (16.7 (4.9) mL kg-1 min-1 versus 21.2 (6.5) mL kg-1 min-1, p < 0.001) and a lower postoperative complication rate (10.4% versus 15.3%; p = 0.018) than males (n = 786). The optimal peak VO2 threshold for predicting postoperative complications was 12.4 mL kg-1 min-1 for females and 22.3 mL kg-1 min-1 for males, respectively. In the multivariable regression model, low non-sex-specific peak VO2 did not independently predict postoperative complications. In contrast, low sex-specific peak VO2 was an independent predictor of postoperative complications (OR 2.29; 95% CI: 1.60, 3.30; p < 0.001). The optimism-corrected AUC-ROC of the sex-specific model was higher compared with the non-sex-specific model (0.73 versus 0.7; DeLong's test: p = 0.021). The sex-specific model classified 39% of the patients more correctly than the baseline model (NRI = 0.39; 95% CI: 0.24, 0.55). In contrast, the non-sex-specific model only classified 9% of the patients more correctly when compared against the baseline model (NRI = 0.09; 95% CI: -0.04, 0.22). Interpretation Our data report sex-specific differences in preoperative CPET-derived functional capacity parameters. Sex-specific peak VO2 thresholds identify patients at increased risk for postoperative complications with a higher discriminatory ability than a sex-unspecific threshold. As such, sex-specific threshold values should be considered in preoperative CPET to potentially improve risk stratification and to guide surgical decision-making, including eligibility for surgery, preoperative optimization strategies (prehabilitation) or seeking non-surgical options.

The original METS study was funded by Canadian Institutes of Health Research, Heart and Stroke Foundation of Canada, Ontario Ministry of Health and Long-Term Care, Ontario Ministry of Research, Innovation and Science, UK National Institute of Academic Anaesthesia, UK Clinical Research Collaboration, Australian and New Zealand College of Anaesthetists, and Monash University.
