Background Frailty is an aggregate variable that encompasses debilitating geriatric conditions, which potentially affects postoperative outcomes. In this study, we evaluate the relationship between clinical frailty and post-cholecystectomy outcomes using a national registry of hospitalized patients. Methods 2011–2017 National Inpatient Sample database was used to identify patients who underwent cholecystectomy. Patients were stratified using the Johns Hopkins ACG frailty definition into binary (frailty and no-frailty) and tripartite frailty (frailty, prefrailty, no-frailty) indicators. The controls were matched to study cohort using 1:1 propensity score-matching and postoperative outcomes were compared. Results Post-match, using the binary term, frail patients (n = 40,067) had higher rates of mortality (OR 2.07 95%CI 1.90–2.25), length of stay, costs, and complications. In multivariate, frailty was associated with higher mortality (aOR 2.06 95%CI 1.89–2.24). When using tripartite frailty term, prefrail (n = 35,595) and frail (n = 4472) patients had higher mortality (prefrailty: OR 2.04 95%CI 1.86–2.23; frailty: OR 2.49 95%CI 1.99–3.13), length of stay, costs, and complications. In multivariate, prefrailty and frailty were associated with higher mortality (prefrailty: aOR 2.02 95%CI 1.84–2.21; frailty: aOR 2.54 95%CI 2.02–3.19). Conclusion This study shows the presence of frailty (and prefrailty) is an independent risk factor of adverse postoperative outcomes in patients undergoing cholecystectomy.

Frailty aggregates a composite of geriatric and elderly features that is classified into a singular syndrome; literature thus far has proven its influence over postoperative outcomes. In this study, we evaluate the effects of frailty following gastrectomy for gastric cancer. 2011–2017 National Inpatient Sample was used to isolate patients with gastric cancer undergoing gastrectomy; from this, the Johns Hopkins ACG frailty criteria were applied to segregate frailty-present and absent populations. The case–controls were matched using propensity-score matching and compared to various endpoints. Post match, there were 1171 with and without frailty who were undergoing gastrectomy for gastric cancer. Those with frailty had higher mortality (6.83 vs 3.50% p

Patients with liver cancer or space-occupying cysts suffer from malnutrition due to compression of gastric and digestive structures, liver and cancer-mediated dysmetabolism, and impaired nutrient absorption. As proportion of these patients requires removal of lesions through hepatic resection, it is important to evaluate the effects of malnutrition on post-hepatectomy outcomes. In our study approach, 2011–2017 National Inpatient Sample was used to isolate in-hospital hepatectomy cases, which were stratified using malnutrition (composite of malnutrition, sarcopenia and weight loss/cachexia). The malnutrition-absent controls were matched to cases using nearest neighbour propensity score matching method and compared with the following endpoints: mortality, length of stay, hospitalisation costs and postoperative complications. There were 2531 patients in total who underwent hepatectomy with matched number of controls from the database; following the match, malnutrition cohort (compared with controls) was more likely to experience in-hospital death (6·60 % v. 5·25 % P < 0·049, OR 1·27, 95 % CI 1·01, 1·61) and was more likely to have higher length of stay (18·10 d v. 9·32 d, P < 0·001) and hospitalisation costs ($278 780 v. $150 812, P < 0·001). In terms of postoperative complications, malnutrition cohort was more likely to experience bleeding (6·52 % v. 3·87 %, P < 0·001, OR 1·73, 95 % CI 1·34, 2·24), infection (6·64 % v. 2·49 %, P < 0·001, OR 2·79, 95 % CI 2·07, 3·74), wound complications (4·5 % v. 1·38 %, P < 0·001, OR 3·36, 95 % CI 2·29, 4·93) and respiratory failure (9·40 % v. 4·11 %, P < 0·001, OR 2·42, 95 % CI 1·91, 3·07). In multivariate analysis, malnutrition was associated with higher mortality (P < 0·028, adjusted OR 1·3, 95 % CI 1·03, 1·65). Thus, we conclude that malnutrition is a risk factor of postoperative mortality in patients undergoing hepatectomy.

Objectives: Since there is increasing number of patients with cirrhosis who require the bariatric procedure due to obesity and obesity-related nonalcoholic steatohepatitis fibrosis, we evaluate the effect of cirrhosis on post-bariatric surgery outcomes.Methods: 2011-2017 National Inpatient Sample was used to isolate bariatric cases, which were stratified by cirrhosis; controls were propensity-score matched to cases and compared to endpoints: mortality, length of stay (LOS), costs, and postoperative complications.Results: From 190,753 patients undergoing bariatric surgery, there were 957 with cirrhosis and 957 matched controls. There was no difference in mortality (0.94 vs 0.52% p = 0.42, OR 1.81 95%CI 0.60-5.41); however, cirrhosis patients had higher LOS (3.36 vs 2.89d p = 0.002), costs ($68,671 vs $61,301 p < 0.001), and bleeding (2.09 vs 0.72% p < 0.001, OR 2.95 95%CI 1.89-4.61). In multivariate, there was no difference in mortality (p = 0.330, aOR 1.73 95%CI 0.58-5.19). In subgroup comparison of cirrhosis patients, those with decompensated cirrhosis had higher mortality (7.69 vs 0.94% p < 0.001, OR 8.78 95%CI 3.41-22.59).Conclusion: The results of this study show compensated cirrhosis does not pose an increased risk toward post-bariatric surgery mortality; however, hepatic decompensation increases the postsurgical risks.

Background & objective: While splenectomy is performed for various trauma and non-trauma indications, there is little information about the impact of cirrhosis on the post-splenectomy outcomes, despite the intricate physiological and vascular connection between the liver and the spleen. Methods: 2011–2017 National Inpatient Sample was used to select patient cases who underwent the splenectomy procedure, who were further stratified using cirrhosis. The cirrhosis-absent controls were matched to the study cohort using propensity score matching with nearest neighbor matching method. Endpoints included mortality, length of stay, hospitalization costs, and postoperative complications. Results: There were 675 patients with cirrhosis and 675 matched controls identified from the database. Cirrhosis cohort had higher mortality (20.0 vs 7.26%, p Conclusions: Cirrhosis is an independent risk factor of postoperative mortality in patients undergoing splenectomy; given this finding, further precautious and multidisciplinary care should be rendered in these at-risk patients with cirrhosis in the setting of splenectomy.

Background We evaluate the effects of paroxysmal arrhythmia on the hospital outcomes of patients admitted with cirrhosis. Research design and methods : 2011-2017 National Inpatient Sample was used to isolate patients with decompensated/compensated cirrhosis, stratified by paroxysmal arrhythmia (supraventricular: PSVT and ventricular: PVT). The cohorts were matched using propensity-score matching and compared to mortality, length of stay, cost, and cardiac complications (cardioversion, cardiogenic shock, cardiac arrest, ventricular fibrillation). Results : In compensated cirrhosis, 2,453 had PSVT with matched controls; 5,274 had PVT with matched controls. Those with PSVT had higher mortality (aOR 1.55 95%CI 1.23-1.95) and higher rates of cardioversion and cardiogenic shock; likewise, those with PVT had higher mortality (aOR 2.41 95%CI 2.09-2.78) and higher rates of all complications. In decompensated cirrhosis, 1,598 had PSVT with matched controls; 4,178 had PVT with matched controls. Those with PSVT had higher mortality (aOR 1.57 95%CI 1.28-1.93) and higher rates of cardioversion, cardiogenic shock, cardiac arrest; those with PVT had higher mortality (aOR 2.25 95%CI 1.98-2.56) and higher rates of all complications. Conclusion : The findings from this study show that in either decompensated or compensated cohort, those with paroxysmal arrhythmias are at a higher risk of in-hospital mortality and adverse cardiac outcomes.

OBJECTIVES In this study, we use a national database to evaluate post-transcatheter (TAVR)/surgical aortic valve replacement (SAVR) outcomes stratified using chronic liver disease (CLD). BACKGROUND In patients undergoing TAVR and SAVR, the surgical risks should be optimized; this includes evaluating hepatic diseases that may pose an operative risk. METHODS 2011-2017 National Inpatient Sample was used to select in-hospital TAVR and SAVR cases, which were stratified according to CLD (cirrhosis, hepatitis B/C, alcoholic/fatty/nonspecific liver disease). The cases-controls were matched using propensity score matching and compared with various endpoints. RESULT After matching for demographics and comorbidities, for TAVR, 606 and 1818 were with or without CLD; for SAVR, 1353 and 4059 were with and without CLD. In TAVR, there was no differences in mortality (2.81% vs. 2.75% OR 1.02 95% CI 0.58-1.78) or length of stay (6.29 vs. 6.44d p = 0.29), and CLD-present patients had marginally increased costs ($228,415 vs. $226,682 p = 0.048). There were no differences in complications. In multivariate, there was no difference in mortality (aOR 1.02 95% CI 0.58-1.79). In SAVR, CLD patients had higher mortality (7.98% vs. 3.23% OR 2.60 95% CI 2.00-3.38), length of stay (13.3 vs. 11.3 days p

Malnutrition is a prominent feature of gastric cancer patients who suffer from gastric outlet obstruction, impaired peristalsis, and cancer-mediated disruptions in metabolic hemostasis. In this study, we systematically evaluate the impact of malnutrition on the postoperative outcome of patients with gastric cancer undergoing gastrectomy.2011-2017 National Inpatient Sample was used to isolate patients with gastric cancer who underwent gastrectomy, who were stratified using malnutrition. The malnutrition-present cohort was matched to the malnutrition-absent controls using 1:1 propensity score-matching analysis, and compared to the following endpoints: mortality, length of stay (LOS), hospitalization costs, and postoperative complications.5309 were identified to have undergone gastric resection procedure for gastric cancer, from which there were 1044 with malnutrition and 1044 matched controls. Malnourished patients had higher mortality (6.80 vs 3.83% p = 0.003, OR 1.83 95% CI 1.23-2.73), LOS (17.2 vs 11.4 d p 0.001), costs ($197,702 vs $124,133 p 0.001), and were more often discharged to rehabilitation facilities. Malnourished patients had higher rates of wound complications (3.64 vs 1.25% p 0.001, OR 3.00 95% CI 1.59-5.66), infection (6.90 vs 3.26% p 0.001, OR 2.20 95% CI 1.45-3.34), and respiratory failure (6.80 vs 3.64% p = 0.002, OR 1.93 95% CI 1.29-2.89). In multivariate analysis, malnourished patients had higher rates of mortality (p = 0.002, aOR 1.87 95% CI 1.25-2.80), length of stay (p 0.001, aOR 1.52 95% CI 1.48-1.55), costs (p 0.001, aOR 1.61 95% CI 1.61-1.61) despite controlling for non-matched hospital variables.In this propensity score matched analysis, malnutrition is associated with increased postoperative mortality, LOS, and hospitalization costs in patients with gastric cancer undergoing gastric resection surgery.

Malnutrition can be prevalently found in patients with significant-to-advanced colorectal cancer, who potential require colorectal resection procedures; to accurately describe the postoperative risks, we used a propensity-score matched comparison of national database to analyze the effects of malnutrition on post-colectomy outcomes.2011-2017 National inpatient Sample was used to isolate inpatient ceases of colorectal resection procedures, which were stratified using malnutrition into malnutrition-present cohort and malnutrition-absent controls; the controls were propensity-score matched with the study cohort using 1:1 ratio and compared to the following endpoints: mortality, length of stay, costs, postoperative complications.After matching, there were 11357 with and without malnutrition who underwent colorectal resection surgery; in comparison, malnourished patients had higher rates of in-hospital mortality (6.14 vs 3.22% p 0.001, OR 1.96 95%CI 1.73-2.23), length of stay (15.4 vs 9.61d p 0.001), costs ($163, 962 vs $102,709 p 0.001), and were more likely to be discharged to non-routine discharges, including short term hospitals, skilled nursing facilities, and home healthcare. In terms of complications, malnourished patients had higher bleeding (2.87 vs 1.68% p 0.001, OR 1.73 95%CI 1.44-2.07), wound complications (4.31 vs 1.34% p 0.001, OR 3.32 95%CI 2.76-3.99), infection (6 vs 2.62% p 0.001, OR 2.38 95%CI 2.07-2.73), and postoperative respiratory failure (7.27 vs 3.37% p 0.001, OR 2.25 95%CI 1.99-2.54).This study demonstrates the presence of malnutrition to be associated with adverse postoperative outcomes including mortality and complications in patients undergoing colorectal resection surgery for colon cancer.

GOALS We specifically evaluate the effect of malnutrition on the infection risks of patients admitted with alcoholic hepatitis using a national registry of hospitalized patients in the United States. BACKGROUND Malnutrition is a common manifestation of alcoholic hepatitis that affects patient outcomes. STUDY 2011 to 2017 National Inpatient Sample was used to isolated patients with alcoholic hepatitis, stratified using malnutrition (protein-calorie malnutrition, sarcopenia, and weight loss/cachexia) and matched using age, gender, and race with 1:1 nearest neighbor matching method. Endpoints included mortality and infectious endpoints. RESULTS After matching, there were 10,520 with malnutrition and 10,520 malnutrition-absent controls. Mortality was higher in the malnutrition cohort [5.02 vs. 2.29%, P

BACKGROUND/OBJECTIVES: Patients with cirrhosis have liver-related immune dysfunction that potentially predisposes the patients to increased influenza infection risk. Our study evaluates this cross-sectional relationship using a national registry of hospital patients. METHODS: This study included the 2011–2017 National Inpatient Sample database. From this, respiratory influenza cases were isolated and stratified using the presence of cirrhosis into a cirrhosis-present study cohort and cirrhosis-absent controls; propensity score matching method was used to match the controls to the study cohort (cirrhosis-present) using a 1:1 matching ratio. The endpoints included mortality, length of stay, hospitalization costs, and influenza-related complications. RESULTS: Following the match, there were 2,040 with cirrhosis and matched 2,040 without cirrhosis admitted with respiratory influenza infection. Compared to the controls, cirrhosis patients had higher in-hospital mortality (7.79 vs 3.43% p < 0.001, OR 2.38 95% CI 1.78–3.17), longer length of stay (7.25 vs 6.52 d p < 0.001), higher hospitalization costs ($70,009 vs $65,035 p < 0.001), and were more likely be discharged to a skilled nursing facility and home healthcare (vs routine home discharges). In terms of influenza-related complications, the cirrhosis cohort had higher rates of sepsis (29.8 vs 22% p < 0.001, OR 1.51 95% CI 1.31–1.74). In the multivariate regression analysis, cirrhosis was associated with higher mortality (p < 0.001, aOR 2.31 95% CI 1.59–3.35) and length of stay (p = 0.018, aOR 1.03 95% CI 1.01–1.06). In subgroup analysis of patients with decompensated (n = 597) versus compensated cirrhosis (n = 1443), those with decompensated cirrhosis had higher rates of in-hospital mortality (12.7 vs 5.75% p < 0.001, OR 2.39 95% CI 1.72–3.32), length of stay (8.85 vs 6.59 d p < 0.001), and hospitalization costs ($92,858 vs $60,556 p < 0.001). In the multivariate analysis, decompensated cirrhosis was associated with increased mortality (p < 0.001, aOR 2.86 95% CI 1.90–4.32). CONCLUSION: This study shows the presence of cirrhosis to result in higher hospital mortality and postinfluenza complications in patients with influenza infection.
