Abstract Background Current guidelines recommend cholecystectomy for patients with mild acute biliary pancreatitis (MABP) during the index admission because it is associated with better outcomes. In this study, we aimed to assess national trends in cholecystectomy during index admissions for MABP and to identify factors associated with cholecystectomy completion and 30-day readmission. Methods Using diagnostic codes and the National Readmissions Database, we identified patients admitted with MABP between 2010 and 2014. Differences in cholecystectomy rates were computed on the basis of various characteristics. We conducted a multivariable analysis to identify factors associated with 30-day readmission and cholecystectomy during the same admission. Results We identified 255,695 unique index MABP cases (41.3% male) and the 30-day readmission rate was 12.6%. Overall, 43.8% underwent cholecystectomy and 25% underwent endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy. We observed a decreasing trend in both procedures during the study period (P < 0.001). In multivariate analysis, odds of 30-day readmission were reduced for patients undergoing ERCP with sphincterotomy (odds ratio, 0.78; 95% confidence interval, 0.74–0.84) or cholecystectomy (odds ratio, 0.37; 95% confidence interval, 0.35–0.39). Conclusions For patients with MABP, cholecystectomy or ERCP with sphincterotomy during the index admission decreased the risk of 30-day readmission. Despite this benefit and national guidelines recommending cholecystectomy during the index MABP admission, the rate of cholecystectomies performed nationally decreased during the study period. Further research is needed to understand the implications and reasons underlying this deviation from guidelines.

Background: Alcohol abuse and liver disease are associated with high rates of 30-day hospital readmission, but factors linking alcoholic hepatitis (AH) to readmission are not well understood. We aimed to determine the incidence rate of 30-day readmission for patients with AH and to evaluate potential predictors of readmission. Methods: We used the Nationwide Readmissions Database to determine the 30-day readmission rate for recurrent AH between 2010 and 2014 and examined trends in readmissions during the study period. We also identified the 20 most frequent reasons for readmission. Multivariate survey logistic regression analysis was used to identify factors associated with 30-day readmission. Results: Of the 61,750 index admissions for AH, 23.9% were readmitted within 30-days. The rate of readmission did not change significantly during the study period. AH, alcoholic cirrhosis, and hepatic encephalopathy were the most frequent reasons for readmission. In multivariate analysis female sex, leaving against medical advice, higher Charlson comorbidity index, ascites, and history of bariatric surgery were associated with earlier readmissions, whereas older age, payer type (private or self-pay/other), and discharge to skilled nursing-facility reduced this risk. Conclusions: The 30-day readmission rate in patients with AH was high and stable during the study period. Factors associated with readmission may be helpful for development of consensus-based expert guidelines, treatment algorithms, and policy changes to help decrease readmission in AH.

Objectives Chronic pancreatitis (CP) hospitalizations along with associated morbidity and costs are increasing. The goal of this study was to use the National Readmission Database to identify the incidence and risk factors for 30-day readmissions among patients with CP. Methods We performed a retrospective analysis of National Readmission Database from January 2013 to December 2013 to determine patient demographic and clinical characteristics predictive of 30-day hospital readmission for adult patients (aged >18 years) discharged with a principle diagnosis of CP. A survey logistic regression model was used to determine the predictive value of selected variables for 30-day readmission. Results In 2013, 12,545 admissions with primary diagnosis of CP were noted, and 30.4% were readmitted within 30 days. Cholecystectomy (odds ratio [OR], 0.53; P = 0.0024) or endoscopic retrograde cholangiopancreatography (OR, 0.70; P = 0.01) during index admission was associated with decreased all-cause readmissions. Pancreatectomy during index admission was associated with reduced (OR, 0.2; P = 0.0005) pancreatitis-related readmissions. Conclusions Hospital readmissions for CP are frequent and pose a significant healthcare burden. Performing cholecystectomy, endoscopic retrograde cholangiopancreatography, or pancreatectomy during index admission was associated with reduced odds of readmission.

Introduction: Chronic pancreatitis (CP) is a common reason for emergency department (ED) visits, but little research has examined ED use by patients with CP. Materials and Methods: The Nationwide Emergency Department Sample (2006 to 2012) was interrogated to evaluate trends in adult ED visits for a primary diagnosis of CP (International Classification of Disease, 9th revision, Clinical Modification code: 577.1), the rates of subsequent hospital admission, and total charges. A survey logistic regression model was used to determine factors associated with hospitalization from the ED. Results: We identified 253,753 ED visits with a primary diagnosis of CP. No significant trends in annual incidence were noted. However, the ED-to-hospitalization rates decreased by 3% per year (P<0.001) and mean ED charges after adjusting for inflation increased by 11.8% per year (P<0.001). Higher Charlson comorbidity index, current smoker status, alcohol use, and biliary-related CP were associated with hospitalization. In hospitalized patients, length of stay decreased by 2.2% per year (P=0.003) and inpatient charges increased by 2.9% per year (P=0.004). Conclusions: Patient characteristics associated with higher risk of hospitalization from the ED deserve further attention.

Introduction: Acute pancreatitis (AP) is the most common gastroenterology-related reason for hospital admission, and a major source of morbidity and mortality in the United States. This study examines the National Emergency Database Sample, a large national database, to analyze trends in emergency department (ED) utilization and costs, risk factors for hospital admission, and associated hospital costs and length of stay (LOS) in patients presenting with AP. Methods: The National Emergency Database Sample (2006 to 2012) was evaluated for trends in ED visits, ED charges, hospitalization rates, hospital charges, and hospital LOS in patients with primary diagnosis of AP (further subcategorized by age and etiology). A survey logistic-regression model was used to determine factors predictive of hospitalization. Results: A total of 2,193,830 ED visits were analyzed. There was a nonsignificant 5.5% ( P =0.07) increase in incidence of ED visits for AP per 10,000 US adults from 2006 to 2012, largely driven by significant increases in ED visits for AP in the 18 to <45 age group (+9.2%; P =0.025), AP associated with alcohol (+15.9%; P =0.001), and AP associated with chronic pancreatitis (+59.5%; P =0.002). Visits for patients aged ≥65 decreased over the time period. Rates of admission and LOS decreased during the time period, while ED and inpatient costs increased (62.1%; P <0.001 and 7.9%; P =0.0011, respectively). Multiple factors were associated with increased risk of hospital admission from the ED, with the strongest predictors being morbid alcohol use [odds ratio (OR), 4.53; P <0.0001], advanced age (age>84 OR, 3.52; P <0.0001), and smoking (OR, 1.75; P <0.0001). Conclusions: Despite a relative stabilization in the overall incidence of ED visits for AP, continued increases in ED visits and associated costs appear to be driven by younger patients with alcohol-associated and acute on chronic pancreatitis. While rates of hospitalization and LOS are decreasing, associated inflation-adjusted costs are rising. In addition, identified risk factors for hospitalization, such as obesity, alcohol use, and increased age, should be explored in further study for potential use in predictive models and clinical improvement projects.

Summary Esophageal cancer (EC) continues to be a major source of morbidity and mortality in the United States. However, there has been a relative dearth of research into hospital utilization in patients with EC. This study examines temporal trends in hospital admissions, length of stay (LOS), mortality, and costs associated with EC. In addition, we also analyzed factors associated with inpatient mortality and LOS. We interrogated National Inpatient Sample (NIS), a large registry of inpatient data, to retrieve information about various demographic and factors associated with hospital stay in patients who were admitted for EC between the years 1998 and 2013 in the United States. After examining trends over time, multivariate analysis was performed to identify factors associated with LOS and mortality. During 1998–2013, 538,776 hospital stays with principal diagnosis of EC were reviewed. Number of hospital stays and inpatient charges increased by 397 per year (±67.8;P &lt; 0.0001) and $3,033 per patient per year (±135; &lt;0.0001) respectively. Mortality and LOS decreased by 0.23% per year (±0.03;P &lt; 0.0001) and 0.07 days per year (±0.006;P &lt; 0.0001) respectively. Multiple factors associated with LOS and mortality were outlined. Despite overall increase in hospital utilization with respect to number of admissions and inpatient charges, inpatient mortality and LOS associated with EC declined. Factors associated with inpatient mortality and LOS may help drive clinical decision-making and influence healthcare or hospital policy.

Introduction: Although gastric cancer (GC) rates have been declining in the United States, it continues to be a major cause of morbidity. This study examined trends in hospital admissions, in-hospital mortality, length of stay (LOS), and inpatient costs related to GC. In addition, various factors associated with in-hospital mortality, LOS, and inpatient costs were examined. Methods: National inpatient sample—the largest publicly available all-payer inpatient care database—was interrogated to obtain information about various demographic and hospital-related factors (including those mentioned above) in patients who were primarily admitted for GC between the years 1998 to 2013. These trends were analyzed. Multivariate analysis was also performed to identify risk factors associated with LOS, costs, and mortality. Results: A total of 679,330 hospital discharges with the principal diagnosis of GC were obtained. Hospital stays increased by approximately 340 stays per year (±110; P=0.00079). However, inpatient mortality rate and LOS declined by 0.36% per year (±0.024%; P<0.0001), and 0.11 days per year (±0.01; P<0.0001), respectively. The inpatient charges have increased at the rate of $3241 per year (±133.3; P<0.0001). Differences in mortality rate, LOS, and inpatient costs were affected by multiple factors. Conclusions: Despite the overall decline in GC incidence, the incidence of hospitalizations per 100,000 US population related to GC did not change significantly. Although LOS and mortality declined, inpatient charges increased over the study period.
