Introduction: Erosive esophagitis (EE) is a severe form of gastroesophageal reflux disease commonly treated with proton pump inhibitors (PPIs). The aim of this retrospective, observational cohort study was to describe the characteristics and healthcare burden of patients with EE.
Methods: We identified adults in the USA with an EE diagnosis between January 1, 2016 and February 28, 2019 in a linked dataset containing electronic health records (EHR) from the Veradigm Network EHR and claims data from Komodo Health.
Aims: The study objectives were to 1) characterize the cost drivers of patients with (HP) and 2) estimate HP-related cost savings following lab-confirmed HP eradication with US guideline-recommended treatment compared to failed eradication.
Methods: We identified adults newly diagnosed with HP between 1/1/2016-12/31/2019 in the Veradigm Electronic Health Record Database linked to claims data (earliest HP diagnosis = index date). For the overall costs analysis, we required patients to have data available for ≥12 months before and after the index date.
Background: Psoriasis is a common autoimmune dermatologic condition which has a pronounced negative impact on patient quality of life and disease burden. Currently, there are a number of treatments available for psoriasis, with differences in efficacy, mechanism of action, mode of administration, adverse effects, and tolerability. However, a reliable, validated patient-reported instrument to address patient expectations and of psoriasis treatment has not been developed.

Objective: To evaluate the efficacy of clarithromycin-based triple eradication regimens over time.
Design: A comprehensive literature review and time-trend analysis.
Background: Japanese guidelines recommend triple therapy with vonoprazan or a proton pump inhibitor (PPI) in combination with antibiotics to treat () infection. While studies have shown improved eradication rates and reduced costs with vonoprazan PPIs, there is little data describing healthcare resource use (HCRU) and treatment patterns.
Objectives: To compare patients treated with a vonoprazan-based or PPI-based regimen for infection in Japan in terms of their characteristics, HCRU, healthcare costs, clinical outcomes, and treatment patterns.
Approximately 36% of the United States (US) population is infected with Helicobacter pylori (HP), a known major risk factor for peptic ulcer disease and gastric cancer. HP eradication reduces the rate of complications; however, the benefits are undermined by rising rates of HP eradication treatment failure. This real-world observational cohort analysis aims to describe HP diagnostic and treatment patterns among insured patients in the US.

Introduction: Erosive esophagitis (EE) occurs when refluxate from the stomach causes T-lymphocyte infiltration of the esophageal mucosa, resulting in mucosal breaks. Currently, therapy with proton-pump inhibitors (PPIs) is the standard treatment for EE in the United States, but few comprehensive reviews exist on the efficacy of PPIs in US populations. Here, we present the most contemporary, thorough analysis of PPI efficacy rates, and identify and characterize patient subgroups at risk for poor healing outcomes.
View Article and Find Full Text PDFObjective: Management of erosive oesophagitis (EE) remains suboptimal, with many patients experiencing incomplete healing, ongoing symptoms, and relapse despite proton pump inhibitor (PPI) treatment. The Study of Acid-Related Disorders investigated patient burden of individuals with EE in a real-world setting.
Design: US gastroenterologists (GIs) or family physicians (FPs)/general practitioners (GPs) treating patients with EE completed a physician survey and enrolled up to four patients with EE for a patient survey, with prespecified data extracted from medical records.
Background And Aims: Effective acid suppression is a crucial component of () eradication regimens. Approved treatments include dual, triple, and quadruple therapies composed of certain antibiotics in combination with proton pump inhibitors (PPIs). Vonoprazan, a potassium-competitive acid blocker, provides more potent and durable acid suppression than PPIs.

Introduction: (Hp) is causal in benign and malignant gastrointestinal diseases. Accordingly, current guidelines recommend Hp eradication in patients with active infection. Unfortunately, treatment failure is common, exposing patients to complications associated with persistent Hp infection and consequences of repeated treatment, including promotion of antibiotic resistance.
View Article and Find Full Text PDFBackground And Aims: eradication rates have declined as antibiotic resistance rates have increased. In addition, adherence to treatment guidelines is suboptimal. It is therefore important that contemporary, real-world evidence of diagnostic and treatment patterns is explored and compared with evidence-based guidelines.

Methods: DMT-treated MS patients (DMT users) and direct-matched controls without MS (1:3) were captured using the IBM MarketScan Commercial Claims and Encounters Database and the Health and Productivity Management Database between 1 January 2009 and 1 January 2017. DMT users were also stratified by route of administration.
Purpose: Compare treatment switching rates and costs among biologic-naive psoriasis patients initiating apremilast or biologics.
Methods: This retrospective claims analysis used IBM MarketScan Commercial and Medicare Supplemental databases to identify patients who initiated apremilast or a biologic (ie, tumor necrosis factor [TNF] or interleukin [IL] inhibitor) for psoriasis treatment between January 1, 2015, and December 31, 2016. A 1:1 propensity score matching was used to adjust for possible selection bias and maximize the number of patients available for analysis.
Treatment switching and healthcare costs were compared among biologic-naive psoriasis patients initiating apremilast or biologics with ≥12 months pre-/post-index continuous enrollment in Optum Clinformatics™ Data Mart. After propensity score matching, switch rates (new therapy post-index) and days between index and switch were assessed. Total and per-patient per-month costs by service type were assessed.
