Preventing Readmissions of Hepatic Encephalopathy: Strategies in the Acute Inpatient, Immediate Postdischarge, and Longitudinal Outpatient Setting.

Hepatic encephalopathy (HE) is a strong predictor of early hospital readmission in patients with cirrhosis. Early hospital readmission increases health care costs and is associated with worse survival. Herein we provide an overview of strategies to prevent hospital readmissions in patients with HE, divided into 3 contexts: (a) acute inpatient, (b) immediate postdischarge, and (c) longitudinal outpatient setting.

The Clinical Impact and Cost-Effectiveness of Surveillance of Incidentally Detected Gastric Intestinal Metaplasia: A Microsimulation Analysis.

BACKGROUND & AIMS: Gastric intestinal metaplasia (GIM) is associated with a higher risk of noncardia intestinal gastric adenocarcinoma (GA). The aim of this study was to estimate lifetime benefits, complications, and cost-effectiveness of GIM surveillance using esophagogastroduodenoscopy (EGD). METHODS: We developed a semi-Markov microsimulation model of patients with incidentally detected GIM, to compare the effectiveness of EGD surveillance with no surveillance at 10-year, 5-year, 3-year, 2-year, and 1-year intervals. We modeled a simulated cohort of 1,000,000 US individuals aged 50 with incidental GIM. Outcome measures were lifetime GA incidence, mortality, number of EGDs, complications, undiscounted life-years gained, and incremental cost-effectiveness ratio with a willingness-to-pay threshold of $100,000/quality-adjusted life-year (QALY). RESULTS: In the absence of surveillance, the model simulated 32.0 lifetime GA cases and 23.0 lifetime GA deaths per 1000 individuals with GIM, respectively. Among surveilled individuals, simulated lifetime GA incidence (per 1000) decreased with shorter surveillance intervals (10-year to 1-year, 11.2-6.1) as did GA mortality (7.4-3.6). Compared with no surveillance, all modeled surveillance intervals yielded greater life expectancy (87-190 undiscounted life-years gained per 1000); 5-year surveillance provided the greatest number of life-years gained per EGD performed and was the cost-effective strategy ($40,706/QALY). In individuals with risk factors of family history of GA or anatomically extensive, incomplete-type GIM intensified 3-year surveillance was cost-effective (incremental cost-effectiveness ratio $28,156/QALY and $87,020/QALY, respectively). CONCLUSIONS: Using microsimulation modeling, surveillance of incidentally detected GIM every 5 years is associated with reduced GA incidence/mortality and is cost-effective from a health care sector perspective. Real-world studies evaluating the impact of GIM surveillance on GA incidence and mortality in the United States are needed.

Cost-effectiveness of endoscopic, surgical and pharmacological obesity therapies: a microsimulation and threshold analyses.

OBJECTIVE: Weight loss interventions to treat obesity include sleeve gastrectomy (SG), lifestyle intervention (LI), endoscopic sleeve gastroplasty (ESG) and semaglutide. We aimed to identify which treatments are cost-effective and identify requirements for semaglutide to be cost-effective. DESIGN: We developed a semi-Markov microsimulation model to compare the effectiveness of SG, ESG, semaglutide and LI for weight loss in 40 years old with class I/II/III obesity. Extensive one-way sensitivity and threshold analysis were performed to vary cost of treatment strategies and semaglutide adherence rate. Outcome measures were incremental cost-effectiveness ratios (ICERs), with a willingness-to-pay threshold of US$100 000/quality-adjusted life-year (QALY). RESULTS: When strategies were compared with each other, ESG was cost-effective in class I obesity (US$4105/QALY). SG was cost-effective in class II obesity (US$5883/QALY) and class III obesity (US$7821/QALY). In class I/II/III, obesity, SG and ESG were cost-effective compared with LI. However, semaglutide was not cost-effective compared with LI for class I/II/III obesity (ICER US$508 414/QALY, US$420 483/QALY and US$350 637/QALY). For semaglutide to be cost-effective compared with LI, it would have to cost less than US$7462 (class III), US$5847 (class II) or US$5149 (class I) annually. For semaglutide to be cost-effective when compared with ESG, it would have to cost less than US$1879 (class III), US$1204 (class II) or US$297 (class I) annually. CONCLUSIONS: Cost-effective strategies were: ESG for class I obesity and SG for class II/III obesity. Semaglutide may be cost-effective with substantial cost reduction. Given potentially higher utilisation rates with pharmacotherapy, semaglutide may provide the largest reduction in obesity-related mortality.

Confusion assessment method accurately screens for hepatic encephalopathy and predicts short-term mortality in hospitalized patients with cirrhosis.

Hepatic encephalopathy (HE), a subtype of delirium, is common in cirrhosis and associated with poor outcomes. Yet, objective bedside screening tools for HE are lacking. We examined the relationship between an established screening tool for delirium, Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and short-term outcomes while comparing its performance with previously established measures of cognitive function such as West Haven criteria (WHC). Prospectively enrolled adults with cirrhosis who completed the CAM-ICU from 6/2014-6/2018 were followed for 90 days. Blinded provider-assigned West Haven Criteria (WHC) and other measures of cognitive function were collected. Logistic regression was used to test associations between CAM-ICU status and outcomes. Mortality prediction by CAM-ICU status was assessed using Area under the Receiver Operating Characteristics curves (AUROC). Of 469 participants, 11% were CAM-ICU( +), 55% were male and 94% were White. Most patients were Childs-Pugh class C (59%). CAM-ICU had excellent agreement with WHC (Kappa = 0.79). CAM-ICU( +) participants had similar demographic features to those CAM-ICU(-), but had higher MELD (25 vs. 19, p < 0.0001), were more often admitted to the ICU (28% vs. 7%, p < 0.0001), and were more likely to be admitted for HE and infection. CAM-ICU( +) participants had higher mortality (inpatient:37% vs. 3%, 30-day:51% vs. 11%, 90-day:63% vs. 23%, p < 0.001). CAM-ICU status predicted mortality with AUROC of 0.85, 0.82 and 0.77 for inpatient, 30-day and 90-day mortality, respectively. CAM-ICU easily screens for delirium/HE, has excellent agreement with WHC, and identifies a hospitalized cirrhosis cohort with high short-term mortality.

Incidence and Risk Factors of Recurrent Clostridioides difficile Infection in Patients With Cirrhosis.

INTRODUCTION: Clostridioides difficile infection (CDI) is common in patients with cirrhosis and is associated with poor outcomes. CDI risk factors in this population have been well characterized; however, risk factors of recurrent CDI (R-CDI) after treatment have not been explored. We sought to estimate the incidence of R-CDI and its associated risk factors in patients with cirrhosis. METHODS: We performed a cohort study of patients with cirrhosis hospitalized with CDI between 2012 and 2016. We collected patient characteristics, including detailed information on the CDI, features of the underlying liver disease, and outcomes including R-CDI, hospital readmission, and mortality. R-CDI was defined as CDI occurring 2-8 weeks after the initial episode. Cox proportional hazards model was used to identify variables independently associated with the outcomes. RESULTS: A total of 257 hospitalized patients with cirrhosis and CDI were included. CDI was community associated in 22.6%. The incidence of R-CDI was 11.9%. R-CDI was not significantly associated with medications at hospital admission or discharge. Independent risk factors of R-CDI included increased Charlson Comorbidity Index (hazard ratio [HR] 1.30; 95% confidence interval [CI]: 1.09-1.55) and use of lactulose (HR 2.58; 95% CI: 1.09-6.09). The 30-day readmission rate was 37%, and readmission was associated with increased Charlson Comorbidity Index (HR 1.12; 95% CI: 1.03-1.23) and Model for End-Stage Liver Disease score (HR 1.04; 95% CI: 1.01-1.07). The 90-day mortality was 22.8%. DISCUSSION: In patients with cirrhosis, R-CDI is associated with comorbidity burden and lactulose use. Attention to these factors might aid clinicians in efforts to prevent R-CDI and improve outcomes in this population.
