| 1 | Trends and outcomes of transarterial chemoembolization in hepatocellular carcinoma:a national survey显示文摘BACKGROUND:Transarterial chemoembolization(TACE) is a palliative procedure frequently used in patients with advanced hepatocellular carcinoma(HCC). We examined the national inpatient trends of TACE and related outcomes in the United States over the last decade.METHODS:We utilized the National Inpatient Sample(2002 to 2012) and performed trend analyses of TACE for HCC in all adult patients(age >18 years). Multivariate analyses for the outcomes of in-hospital 'procedure-related complications'(PRCs) and 'post-procedure complications'(PPCs) were performed. We also compared early(2002 to 2006) and late(2007 to 2012) eras by multivariate analyses to identify predictors of complications, healthcare resource utilization and mortality.RESULTS:Overall, 19058 patients underwent TACE for HCC where PRCs and PPCs were seen in 24.2% and 17.6% of patients, respectively. The overall trends in the use of TACE(P<0.001) and associated PRCs(P=0.006) were observed to be increasing. There was less mortality [adjusted Odds ratio(a OR):0.58; 95% CI:0.41, 0.82], reduced length of hospital stay(-1.87 days; 95% CI:-2.77,-0.97) and increased hospital charges($19232; 95% CI:11013, 27451) in the late era. Additionally, there was increased mortality(a OR:4.07; 95% CI:2.96, 5.59), PRCs(a OR:3.21; 95% CI:2.56, 4.02), and PPCs(a OR:2.70; 95% CI:2.11, 3.46) among patients with coagulopathy.CONCLUSIONS:There is an increasing trend of TACE utilization in HCC. However, the outcomes are worse in patients with coagulopathy. Although PRCs have increased, mortality has decreased in recent years. These findings should be considered during TACE evaluation in patients with HCC. | Khalid Mumtaz Nishi Patel Rohan M Modi Vihang Patel Alice Hinton James Hanje Sylvester M Black Somashaker Krishna | 2017 | Hepatobiliary & Pancreatic Diseases International2017，16，6： | 2 |
| 2 | African Americans are less likely to receive curative treatment for hepatocellular carcinoma显示文摘AIM To determine if racial disparities continue to exist in the treatment of hepatocellular carcinoma(HCC).METHODS A retrospective database analysis using the Nationwide Inpatient Sample was performed including patients with a primary diagnosis of HCC. Univariate and multivariate analyses were utilized to determine racial disparities in liver decompensation, treatment, inpatient mortality, and metastatic disease.RESULTS A total of 62604 patients with HCC were included consisting of 32428 Caucasian, 9726 African-American, 8988 Hispanic, and 11462 patients of other races. Caucasian patients were more likely to undergo curative therapies of liver transplant(OR: 2.66, 95%CI: 1.92-3.68), resection(OR: 1.82, 95%CI: 1.48-2.23), and ablation(OR: 1.77, 95%CI: 1.36-2.30) than African-American patients. Hispanic patients were more likely to undergo transplant(OR: 2.18, 95%CI: 1.40-3.39) and ablation(OR: 1.46, 95%CI:1.05-2.03) than African-American patients. Patients of other races were more likely to receive a liver transplant(OR: 2.41, 95%CI: 1.62-3.61), resection(OR: 1.79 95%CI: 1.39-2.32), and ablation(OR: 2.03, 95%CI: 1.47-2.80) than African-American patients. There are no differences in the rates of transarterial chemoembolization between races.CONCLUSION Racial disparities in HCC treatment exist despite emphasis to support equality in healthcare. African-American patients are less likely to undergo curative treatments for HCC. | Lindsay A Sobotka Alice Hinton Lanla F Conteh | 2018 | World Journal of Hepatology2018，10，11： | 1 |
| 3 | Paracentesis in cirrhotics is associated with increased risk of 30-day readmission显示文摘AIM To determine the readmission rate, its reasons, predictors, and cost of 30-d readmission in patients with cirrhosis and ascites.METHODS A retrospective analysis of the nationwide readmission database(NRD) was performed during the calendar year 2013. All adults cirrhotics with a diagnosis of ascites,spontaneous bacterial peritonitis, or hepatic encephalopathy were identified by ICD-9 codes. Multivariate analysis was performed to assess predictors of 30-d readmission and cost of readmission.RESULTS Of the 59597 patients included in this study, 18319(31%) were readmitted within 30 d. Majority(58%) of readmissions were for liver related reasons. Paracentesis was performed in 29832(50%) patients on index admission. Independent predictors of 30-d readmission included age < 40(OR: 1.39; CI: 1.19-1.64), age 40-64(OR: 1.19; CI: 1.09-1.30), Medicaid(OR: 1.21; CI: 1.04-1.41) and Medicare coverage(OR: 1.13; CI: 1.02-1.26), > 3 Elixhauser comorbidity(OR: 1.13; CI: 1.05-1.22), nonalcoholic cirrhosis(OR: 1.16; CI: 1.10-1.23), paracentesis on index admission(OR: 1.28; CI: 1.21-1.36) and having hepatocellular carcinoma(OR: 1.21; CI: 1.05; 1.39). Cost of index admission was similar in patients readmitted and not readmitted(P-value: 0.34); however cost of care was significantly more on 30 d readmission($30959 ± 762) as compared to index admission($12403 ± 378), P-value: < 0.001.CONCLUSION Cirrhotic patients with ascites have a 33% chance of readmission within 30-d. Younger patients, with public insurance, nonalcoholic cirrhosis and increased comorbidity who underwent paracentesis are at increased risk of readmission. Risk factors for unplanned readmission should be targeted given these patients have higher healthcare utilization. | Lindsay A Sobotka Rohan M Modi Akshay Vijayaraman A James Hanje Anthony J Michaels Lanla F Conteh Alice Hinton Ashraf El-Hinnawi Khalid Mumtaz | 2018 | World Journal of Hepatology2018，10，6： | 1 |
| 4 | Diagnosis of morbid obesity may not impact healthcare utilization for orthotopic liver transplantation:A propensity matched study显示文摘AIM To study mortality, length of stay, and total charges in morbidly obese adults during index hospitalization for orthotopic liver transplantation.METHODS The Nationwide Inpatient Sample was queried to obtain demographics, healthcare utilization, post orthotopic liver transplantation(OLT) complications, and short term outcomes of OLT performed from 2003 to 2011(n = 46509). We divided patients into those with [body mass index(BMI) ≥ 40] and without(BMI < 40) morbid obesity. Multivariable logistic regression analysis was performedto characterize differences in in-hospital mortality, length of stay(LOS), and charges for OLT between patients with and without morbid obesity after adjusting for significant confounders. Additionally, propensity matching was performed to further validate the results.RESULTS Of the 46509 patients who underwent OLT during the study period, 818(1.8%) were morbidly obese. Morbidly obese recipients were more likely to be female(46.8% vs 33.4%, P = 0.002), Caucasian(75.2% vs 67.8%, P = 0.002), in the low national income quartile(32.3% vs 22.5%, P = 0.04), and have ≥ 3 comorbidities(modified Elixhauser index; 83.9% vs 45.0%, P < 0.001). Morbidly obese patient also had an increase in procedure related hemorrhage(P = 0.028) and respiratory complications(P = 0.043). Multivariate and propensity matched analysis showed no difference in mortality(OR: 0.70; 95%CI: 0.27-1.84, P = 0.47), LOS(β:-4.44; 95%CI:-9.93, 1.05, P = 0.11) and charges for transplantation(β: $15693; 95%CI:-51622-83008, P = 0.64) between the two groups. Morbidly obese patients were more likely to have transplants on weekdays(81.7%) as compared to those without morbid obesity(75.4%, P = 0.029).CONCLUSION Morbid obesity may not impact in-hospital mortality and health care utilization in OLT recipients. However, morbidly obese patients may be selected after careful assessment of co-morbidities. | Joshua R Peck Nicholas Latchana Anthony Michaels Adam J Hanje Alice Hinton Elmahdi A Elkhammas Sylvester M Black Khalid Mumtaz | 2017 | World Journal of Hepatology2017，9，12： | 0 |
| 5 | Accuracy of virtual chromoendoscopy in differentiating gastric antral vascular ectasia from portal hypertensive gastropathy:A proof of concept study显示文摘BACKGROUND Accurate detection of gastric antral vascular ectasia(GAVE)is critical for proper management of cirrhosis-related gastrointestinal bleeding.However,endoscopic diagnosis of GAVE can be challenging when GAVE overlaps with severe portal hypertensive gastropathy(PHG).AIM To determine the added diagnostic value of virtual chromoendoscopy to high definition white light for real-time endoscopic diagnosis of GAVE and PHG.METHODS We developed an I-scan virtual chromoendoscopy criteria for diagnosis of GAVE and PHG.We tested our criteria in a cross-sectional cohort of cirrhotic adults with GAVE and PHG when high-definition white light endoscopy(HDWLE)diagnosis was in doubt.We then compared the accuracy of I-scan vs HDWLE alone to histology.RESULTS Twenty-three patients were included in this study(65.2%Caucasians and 60.9%males).Chronic hepatitis C was the predominant cause of cirrhosis(43.5%)and seven adults(30.4%)had confirmed GAVE on histology.I-scan had higher sensitivity(100%vs 85.7%)and specificity(75%vs 62.5%)in diagnosing GAVE compared to HDWLE.This translates into a higher,albeit not statistically significant,accuracy of I-scan in detecting GAVE compared to HDWLE alone(82%vs 70%).I-scan was less likely to lead to an accurate diagnosis of GAVE in patients on dialysis(P<0.05)and in patients with elevated creatinine(P<0.05).Iscan had similar accuracy to HDWLE in detecting PHG.CONCLUSION This pilot work supports that virtual chromoendoscopy may obviate the need for biopsies when the presence of GAVE is in doubt.Larger studies are needed to assess the impact of virtual chromoendoscopy on success of endoscopic therapy for GAVE. | Ahmad M Al-Taee Mark P Cubillan Alice Hinton Lindsay A Sobotka Alex S Befeler Christine Y Hachem Hisham Hussan | 2021 | World Journal of Hepatology2021，13，12： | 0 |
| 6 | Hospital outcomes and early readmission for the most common gastrointestinal and liver diseases in the United States:Implications for healthcare delivery显示文摘BACKGROUND Gastrointestinal(GI)and liver diseases contribute to substantial inpatient morbidity,mortality,and healthcare resource utilization.Finding ways to reduce the economic burden of healthcare costs and the impact of these diseases is of crucial importance.Thirty-day readmission rates and related hospital outcomes can serve as objective measures to assess the impact of and provide further insights into the most common GI ailments.AIM To identify the thirty-day readmission rates with related predictors and outcomes of hospitalization of the most common GI and liver diseases in the United States.METHODS A cross-sectional analysis of the 2012 National Inpatient Sample was performed to identify the 13 most common GI diseases.The 2013 Nationwide Readmission Database was then queried with specific International Classification of Diseases,Ninth Revision,Clinical Modification codes.Primary outcomes were mortality(index admission,calendar-year),hospitalization costs,and thirty-day readmission and secondary outcomes were predictors of thirty-day readmission.RESULTS For the year 2013,the thirteen most common GI diseases contributed to 2.4 million index hospitalizations accounting for about$25 billion.The thirty-day readmission rates were highest for chronic liver disease(25.4%),Clostridium difficile(C.difficile)infection(23.6%),functional/motility disorders(18.5%),inflammatory bowel disease(16.3%),and GI bleeding(15.5%).The highest index and subsequent calendar-year hospitalization mortality rates were chronic liver disease(6.1%and 12.6%),C.difficile infection(2.3%and 6.1%),and GI bleeding(2.2%and 5.0%),respectively.Thirty-day readmission correlated with any subsequent admission mortality(r=0.798,P=0.001).Medicare/Medicaid insurances,≥3 Elixhauser comorbidities,and length of stay>3 d were significantly associated with thirty-day readmission for all the thirteen GI diseases.CONCLUSION Preventable and non-chronic GI disease contributed to a significant economic and health burden comparable to chronic GI conditions,providing a window of opportunity for improving healthcare delivery in reducing its burden. | Somashekar G Krishna Brandon K Chu Alecia M Blaszczak Gokulakrishnan Balasubramanian Hisham Hussan Peter P Stanich Khalid Mumtaz Alice Hinton Darwin L Conwell | 2021 | World Journal of Gastrointestinal Surgery2021，13，2： | 0 |
| 7 | Outcomes of inpatient cholecystectomy among adults with cystic fibrosis in the United States显示文摘BACKGROUND Symptomatic biliary and gallbladder disorders are common in adults with cystic fibrosis(CF)and the prevalence may rise with increasing CF transmembrane conductance regulator modulator use.Cholecystectomy may be considered,but the outcomes of cholecystectomy are not well described among modern patients with CF.AIM To determine the risk profile of inpatient cholecystectomy in patients with CF.METHODS The Nationwide Inpatient Sample was queried from 2002 until 2014 to investigate outcomes of cholecystectomy among hospitalized adults with CF compared to controls without CF.A propensity weighted sample was selected that closely matched patient demographics,patient’s individual comorbidities,and hospital characteristics.The propensity weighted sample was used to compare outcomes among patients who underwent laparoscopic cholecystectomy.Hospital outcomes of open and laparoscopic cholecystectomy were compared among adults with CF.RESULTS A total of 1239 inpatient cholecystectomies were performed in patients with CF,of which 78.6%were performed laparoscopically.Mortality was<0.81%,similar to those without CF(P=0.719).In the propensity weighted analysis of laparoscopic cholecystectomy,there was no difference in mortality,or pulmonary or surgical complications between patients with CF and controls.After adjusting for significant covariates among patients with CF,open cholecystectomy was independently associated with a 4.8 d longer length of stay(P=0.018)and an$18449 increase in hospital costs(P=0.005)compared to laparoscopic cholecystectomy.CONCLUSION Patients with CF have a very low mortality after cholecystectomy that is similar to the general population.Among patients with CF,laparoscopic approach reduces resource utilization and minimizes post-operative complications. | Mitchell L Ramsey Lindsay A Sobotka Somashekar G Krishna Alice Hinton Stephen E Kirkby Susan S Li Michael P Meara Darwin L Conwell Peter P Stanich | 2021 | World Journal of Gastrointestinal Endoscopy2021，13，9： | 0 |
| 8 | Women receive more inpatient resections and ablations for hepatocellular carcinoma than men显示文摘AIM To evaluate disparities in the treatment of hepatocellular carcinoma(HCC) based on gender.METHODS A retrospective database analysis using the Nationwide Inpatient Sample(NIS) was performed between 2010 and 2013. Adult patients with a primary diagnosis of hepatocellular carcinoma determined by International Classification of Disease 9(ICD-9) codes were included. Univariate analysis and multivariate logistic regressions were performed to analyze differences in treatment, mortality, features of decompensation, and metastatic disease based on the patient's gender.RESULTS The analysis included 62582 patients with 45908 men and 16674 women. Women were less likely to present with decompensated liver disease(OR = 0.84, P < 0.001) and had less risk of inpatient mortality when compared to men(OR = 0.75, P < 0.001). Women were more likely to receive inpatient resection(OR = 1.31, P < 0.001) or an ablation(OR = 1.22, P = 0.028) than men. There was no significant difference between men and women in regard to liver transplantation and transcatheter arterial chemoembolization(TACE).CONCLUSION Gender impacts treatment for hepatocellular carcinoma. Women are more likely to undergo an ablation or resection then men. Gender disparities in transplantation have resolved. | Lindsay Sobotka Alice Hinton Lanla Conteh | 2017 | World Journal of Hepatology2017，9，36： | 0 |
