Development and validation of a novel score for predicting perioperative major adverse cardiovascular events in patients with stable coronary artery disease undergoing noncardiac surgery. Int J Cardiol 2024; 405:131982. [PMID: 38521511 DOI: 10.1016/j.ijcard.2024.131982] [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: 12/01/2023] [Revised: 02/01/2024] [Accepted: 03/17/2024] [Indexed: 03/25/2024]
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.

Abstract
Prehabilitation is an intervention that occurs between cancer diagnosis and the start of an acute treatment. It involves physical, nutritional, and psychological assessments to establish a baseline functional level and provide targeted interventions to improve a person's health and prevent future impairments. Prehabilitation has been applied to surgical oncology and has shown positive results at improving functional capacity, reducing hospital stay, decreasing complications, and enhancing health-related quality of life. The importance of collaboration between various healthcare professionals and the implementation of multimodal interventions, including exercise training, nutrition optimization, and emotional support is discussed in this manuscript. The need for screening and assessment of conditions such as sarcopenia, frailty, or low functional status in order to identify patients who would benefit the most from prehabilitation is vital and should be a part of all prehabilitation programs. Exercise and nutrition play complementary roles in prehabilitation, enhancing anabolism and performance. However, in the presence of malnutrition and sarcopenia, exercise-related energy expenditure without sufficient protein intake can lead to muscle wasting and further deterioration of functional capacity, thus special emphasis on nutrition and protein intake should be made in these cases. Finally, the challenges and the need for a paradigm shift in perioperative care are discussed to effectively implement personalized prehabilitation programs.

Abstract
Preoperative care exists as part of perioperative continuum during which anesthesiologists and surgeons optimize patients for surgery. These multispecialty efforts are important, particularly for patients with complex medical histories and those requiring major surgery. Preoperative care improves planning and determines the clinical pathway and discharge disposition. The role of nonmedical social factors in the preoperative planning is not well described in anesthesiology. Research to improve outcomes based on social factors is not well described for anesthesiologists but could be instrumental in decreasing disparities and advancing health equity in surgical patients.

Abstract
More than 300 million surgeries are performed worldwide annually. Established perioperative centres in the UK, USA and Australia have demonstrated the impact of improving perioperative care in reducing costs, increasing patient satisfaction and improving population health. Likewise, the surgical burden of care in Asia is increasing, but with sociocultural, economic and epigenetic differences compared to the west. As Singapore's largest hospital, the Singapore General Hospital pre-admission perioperative clinic sees about 20,000 patients annually. We aim to illustrate Singapore General Hospital's perioperative model of care to contribute to the paucity of literature describing perioperative programme implementation within Asia, and to encourage the cross-sharing of perioperative practices internationally. Our perioperative framework navigates risk assessment, risk counselling, and mitigation of health, medical and functional risks to better patients' perioperative outcomes and population health. We have implemented evidence-based pathways for common conditions such as anaemia and malnutrition, including a multidisciplinary programme for the elderly to tackle frailty and reduce length of stay. We describe how we have enhanced local risk profiling with the Combined Assessment of Risk Encountered in Surgery surgical risk calculator derived locally using a gradient boosting machine learning model. Finally, we report clinical outcomes of these interventions and discuss further challenges and new initiatives at each tier of our perioperative model. Our perioperative care model provides a framework that other centres can adopt to promote value-driven care, while catering for differences in the Asian population, thereby promoting evidence-based improvements in the area of perioperative medicine.

Construct validity and responsiveness of the Duke Activity Status Index (DASI) as a measure of recovery after colorectal surgery. Surg Endosc 2022; 36:8490-8497. [PMID: 35212822 DOI: 10.1007/s00464-022-09145-6] [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: 09/03/2021] [Accepted: 02/15/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Returning to preoperative levels of physical function is highly valued by patients recovering from surgery. The Duke Activity Status Index (DASI, a 12-item questionnaire) may be a simple yet robust tool to assess postoperative recovery of functional capacity. This study assessed construct validity and responsiveness of the DASI as a measure of recovery after colorectal surgery. METHODS Data from a trial on early mobilization after colorectal surgery were analyzed. Patients completed the DASI questionnaire preoperatively and at postoperative weeks (POW) 2 and 4. Construct validity was assessed by testing the primary a priori hypotheses that postoperative DASI scores (1) are higher in patients without vs with postoperative complications and (2) correlate with six-minute walk test distance (6MWD). Exploratory analyses assessed the association between DASI scores and (1) preoperative physical status [higher (ASA ≤ 2) vs lower (ASA > 2)], (2) stoma creation (no stoma vs stoma), (3) age [younger (≤ 75 years) vs older (> 75 years)], (4) time to readiness for discharge [shorter (≤ 4 days) vs longer (> 4 days)], and (5) surgical approach (laparoscopic vs open). Responsiveness was assessed by testing a priori hypotheses that DASI scores are higher (1) preoperatively vs at POW2 and (2) at POW4 vs POW2. Mean differences in DASI scores were obtained using linear regression. The association between DASI and 6MWD was assessed via Pearson correlation. RESULTS We analyzed data from 100 patients undergoing colorectal surgery (mean age 65; 57% male; 81% laparoscopic). Mean DASI scores were 47.9 ± 12.1 preoperatively, 22.4 ± 12.7 at POW2, and 33.2 ± 15.7 at POW4. The data supported our two primary construct validity hypotheses, as well as 3/5 exploratory hypotheses. Both responsiveness hypotheses were supported. CONCLUSIONS Our findings support that the DASI questionnaire can be a useful tool to assess postoperative recovery of functional capacity in research and clinical practice.

Abstract
BACKGROUND Complications are common after colorectal surgery and remain a target for quality improvement. Lower preoperative physical functioning is associated with poor postoperative outcomes, but assessment often relies on subjective judgment or resource-intensive tests. Recent literature suggests that self-reported functional capacity, measured using the Duke Activity Status Index (DASI), is a strong predictor of postoperative outcomes. This study aimed to estimate the extent to which DASI predicts 30-day complications after colorectal surgery. METHODS In this observational study, 100 patients undergoing colorectal resection [median age 63, 57% men, 81% laparoscopic, 37% rectal surgery] responded to DASI two weeks preoperatively. Complications were classified according to Clavien-Dindo and quantified using the comprehensive complication index (CCI). Our primary analysis targeted the relationship between preoperative DASI and odds of complications. Secondary analyses focused on 30-day severe complications, CCI, readmissions, and length of stay (LOS). We also explored the predictive ability of DASI with scores dichotomized based on a previously validated threshold (≤ 34). RESULTS Mean preoperative DASI was 48 ± 12. Forty-six patients (46%) experienced 30-day complications (8% severe, CCI 9.6 ± 15). Lower DASI scores were associated with higher odds of complications (OR 1.08, 95%CI 1.03-1.14; p = 0.001). Preoperative DASI was also an independent predictor of severe complications, CCI, and readmissions. The predictive ability was supported when scores were dichotomized at ≤ 34. CONCLUSION DASI is a significant predictor of postoperative complications after colorectal surgery. This questionnaire can be easily implemented in clinical practice to identify patients with low preoperative functional capacity and target interventions to those at higher risk.
