Nonalcoholic fatty liver disease (NAFLD) can progress to advanced fibrosis, which, in the nonsurgical population, is associated with poor hepatic and extrahepatic outcomes. Despite its high prevalence, NAFLD and related liver fibrosis may be overlooked during the preoperative evaluation, and the role of liver fibrosis as an independent risk factor for surgical-related mortality has yet to be tested. The aim of this study was to assess whether fibrosis-4 (FIB-4), which consists of age, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelets, a validated marker of liver fibrosis, is associated with postoperative mortality in the general surgical population.A historical cohort of patients undergoing general anesthesia at an academic medical center between 2014 and 2018 was analyzed. Exclusion criteria included known liver disease, acute liver disease or hepatic failure, and alcohol use disorder. FIB-4 score was categorized into 3 validated predefined categories: FIB-4 ≤1.3, ruling out advanced fibrosis;1.3 and2.67, inconclusive; and ≥2.67, suggesting advanced fibrosis. The primary analytic method was propensity score matching (FIB-4 was dichotomized to indicate advanced fibrosis), and a secondary analysis included a multivariable logistic regression.Of 19,861 included subjects, 1995 (10%) had advanced fibrosis per FIB-4 criteria. Mortality occurred intraoperatively in 15 patients (0.1%), during hospitalization in 272 patients (1.4%), and within 30 days of surgery in 417 patients (2.1%). FIB-4 ≥2.67 was associated with increased intraoperative mortality (odds ratio [OR], 3.63; 95% confidence interval [CI], 1.25-10.58), mortality during hospitalization (OR, 3.14; 95% CI, 2.37-4.16), and within 30 days from surgery (OR, 2.46; 95% CI, 1.95-3.10), after adjusting for other risk factors. FIB-4 was related to increased mortality in a dose-dependent manner for the 3 FIB-4 categories ≤1.3 (reference),1.3 and2.67, and ≥2.67, respectively; during hospitalization (OR, 1.89; 95% CI, 1.34-2.65 and OR, 4.70; 95% CI, 3.27-6.76) and within 30 days from surgery (OR, 1.77; 95% CI, 1.36-2.31 and OR, 3.55; 95% CI, 2.65-4.77). In a 1:1 propensity-matched sample (N = 1994 per group), the differences in mortality remained. Comparing the FIB-4 ≥2.67 versus the FIB-42.67 groups, respectively, mortality during hospitalization was 5.1% vs 2.2% (OR, 2.70; 95% CI, 1.81-4.02), and 30-day mortality was 6.6% vs 3.4% (OR, 2.26; 95% CI, 1.62-3.14).A simple liver fibrosis marker is strongly associated with perioperative mortality in a population without apparent liver disease, and may aid in future surgical risk stratification and preoperative optimization.

Assessment of frailty can help surgeons predict perioperative risk and guide preoperative counseling. However, current methods are often cumbersome in the clinical setting. We prospectively compared the effectiveness of a rapid picture based Clinical Frailty Scale (CFS-9) assessed by patient and surgeon against reference standard Fried Frailty Index in older patients with pelvic floor conditions.We enrolled 71 patients between March 2018 and June 2019. Frailty assessment using CFS-9 (scale ranging from very fit to terminally ill) was performed followed by the Fried Frailty Index, a validated tool of 5 measures (shrinking, physical energy, activity, grip strength, walking speed). Correlations and agreement between Fried Frailty Index and CFS-9 scores from the treating surgeon, a second surgeon (surgeon 2) and patient were analyzed using sensitivity, specificity, area under the curve and Cohen's Kappa.The patient cohort was mostly female (97.2%), with a mean age (±SD) of 73.0 (±5.9) years and 23.9% were frail using the Fried Frailty Index. Compared to the Fried Frailty Index, CFS-9 scores of the treating surgeon, surgeon 2 and patient had AUC values (95% CI) of 0.86 (0.77-0.86), 0.91 (0.84-0.91) and 0.88 (0.79-0.88), respectively. As assessed by Cohen's Kappa the CFS-9 scores all had substantial (surgeon 2, Kappa 0.66, 95% CI 0.46-0.85 or moderate (all other CFS-9 measures, Kappa 0.44 to 0.58) agreement with the Fried Frailty Index scores.Rapid and effective validated tools to screen for frailty are needed in the clinical setting. CFS-9 is an excellent predictor of frailty compared to the Fried Frailty Index for patients with pelvic floor conditions.

Age-related changes in skin contribute to impaired wound healing after surgical procedures. Changes in skin with age include decline in thickness and composition, a decrease in the number of most cell types, and diminished microcirculation. The microcirculation provides tissue perfusion, fluid homeostasis, and delivery of oxygen and other nutrients. It also controls temperature and the inflammatory response. Surgical incisions cause further disruption of the microvasculature of aged skin. Perioperative management can be modified to minimize insults to aged tissues. Judicious use of fluids, maintenance of normal body temperature, pain control, and increased tissue oxygen tension are examples of adjustable variables that support the microcirculation. Anesthetic agents influence the microcirculation of a combination of effects on cardiac output, arterial pressure, and local microvascular changes. The authors examined the role of anesthetic management in optimizing the microcirculation and potentially improving postoperative wound repair in older persons.
