Wilson's Disease: An Analysis of Health Care Use and Cost Burden of Commercially Insured Adults in the United States.

The economic and health care use burdens of Wilson's disease (WD) are unknown. In this study, we aimed to quantify this health care resource use and economic burden. We performed a retrospective case-control analysis of individuals in the Truven Health MarketScan Commercial Claims database (2007-2017). Using propensity scores, 424 WD cases were matched 1:1 to chronic liver disease (CLD) controls without WD. Total and service-specific parameters, expressed in monthly averages, were quantified for the 6-month pre-WD diagnosis versus the 12-month period after diagnosis. Wilcoxon signed-rank tests and McNemar tests were used to examine incremental differences in burden between cases and controls. Adjusted multivariable generalized linear regression models were used to compare health care burdens. Relative to the 6-month pre-WD diagnosis, the 12 months after diagnosis had more claims per patient (2.87 vs. 3.35; P < 0.0001) and increased per patient health care costs (US $2,089 vs. US $3,887; P < 0.0001). WD cases incurred US $1,908 more in total unadjusted costs compared to controls in the 12-month postindex date monthly averages. The increase in claims was primarily due to outpatient visits (1.62 vs. 1.82) and pharmaceutical claims (1.11 vs. 1.37). Cases also had higher health care costs for inpatient admissions (US $559 vs. US $1,264), outpatient visits (US $770 vs. US $1,037), and pharmaceutical claims (US $686 vs. US $1,489). Conclusion: WD is associated with significant health care cost and use burdens driven by increased inpatient admissions, outpatient visits, and pharmaceutical claims.

Incidence of Non-variceal Upper Gastrointestinal Bleeding Worsens Outcomes with Acute Coronary Syndrome: Result of a National Cohort.

INTRODUCTION: Upper gastrointestinal bleeding (UGIB) is a feared complication of acute coronary syndrome (ACS) and has been shown to increase morbidity and mortality. Our aim was to assess the incidence of non-variceal UGIB in patients with ACS in a national cohort and its impact on in-hospital mortality, length of stay (LOS), and cost of hospitalization. METHODS: This was a retrospective cohort study analyzing the 2016 Nationwide Inpatient Sample (NIS) utilizing ICD 10 CM codes. Principal discharge diagnoses of ACS (STEMI, NSTEMI, and UA) in patients over 18 years old were included. Non-variceal UGIB with interventions including endoscopy, angiography, and embolization were also evaluated. Primary outcome was the national incidence of concomitant non-variceal UGIB in the setting of ACS. Secondary outcomes included in-hospital mortality, length of stay, and cost of stay. RESULTS: A total of 661,404 discharges with principal discharge diagnosis of ACS in 2016 were analyzed. Of the included cohort, 0.80% (n = 5324) were complicated with non-variceal UGIB with increased frequency in older patients (OR 1.03, 95% CI 1.03-1.04; p = 0.0001). Despite endoscopic evaluation, 17.35% (n = 744) underwent angiography. After adjustment of confounders, inpatient mortality was significantly higher in patients with UGIB (OR 2.07, 95% CI 1.63-2.63, p = 0.0001). Non-variceal UGIB also led to significantly longer LOS (10.38 days vs 4.37 days, p = 0.0001) and cost of stay ($177,324 vs $88,468, p = 0.0001). DISCUSSION: Our study shows that the national incidence of non-variceal UGIB complicating ACS is low at less than 1%, but resulted in significantly higher inpatient mortality, LOS, and hospitalization charges.

Portal Hypertension and Chronic Kidney Disease Significantly Increase the Risk of Early Unplanned Readmissions in GAVE- Related Admissions.

BACKGROUND AND AIMS: Gastric antral vascular ectasia (GAVE) is an uncommon cause of non-variceal upper gastrointestinal bleeding that is characterized by dilation of blood vessels in the antrum of the stomach. Various co-morbidities are associated with the development of GAVE, but the impact of co-morbidities on unplanned GAVE readmissions is unclear. The aim of this study was to assess the national incidence, 30-day mortality rate, and 30-day readmissions related to GAVE. Secondary outcomes were evaluation of predictors of early readmission, hospital length of stay (LOS) and total hospitalization charges. METHODS: Using the 2016 National Readmission Database, we analyzed discharges for GAVE. ICD-10 CM codes were utilized to identify associated comorbidities and inpatient procedures during the index admission. 30-day readmissions were identified for GAVE. Secondary measures of outcomes including LOS and hospitalization charges were also calculated. Risk factors for early readmission were also evaluated using multivariate analysis to adjust for confounders. RESULTS: A total of 18,375 index admissions for GAVE were identified. 20.49% (n=3,720) of the discharged patients were readmitted within 30 days. 30-day mortality of GAVE-related admissions was 1.82% (n=335). Early readmissions accounted for 20,157 hospital days along with $189 million in hospitalization costs. Multivariate analysis revealed that the presence of portal hypertension (OR 1.63; 95% CI 1.37-1.93; p=0.0001) and chronic kidney disease (CKD) (OR 1.62, 95% CI 1.44-1.82; p<0.0001) significantly increased the odds of early readmission. CONCLUSIONS: Our analysis demonstrates that the overall 30-day mortality rate of GAVE-related admissions is relatively low, but the 30-day readmission rate is significantly high. Patients with comorbid CKD and portal hypertension have a significantly higher risk of readmission. Further studies are required to determine if therapeutic interventions such as argon plasma coagulation or radiofrequency ablation during the index admission may prevent readmissions in these specific subgroups.
