A Linked Electronic Medical Record-Claims Analysis of the Clinical and Economic Outcomes of Patients Coded for Erosive Esophagitis in the United States
Abstract
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. Patients were required to have 1 year of baseline data and 3 years of follow-up data. Patients were stratified by the number of PPI lines of therapy (LOT) during the 4-year study period. We descriptively captured patient characteristics and treatment patterns, along with all-cause and EE-related healthcare utilization and costs.
Results: Among the 158,347 qualifying adults with EE, 71,958 (45.4%) had 1 PPI LOT, 14,985 (9.5%) had 2 LOTs, 15,129 (9.6%) had 3+ LOTs, and 56,275 (35.5%) did not fill a PPI prescription. Omeprazole and pantoprazole comprised more than 70% of any LOT, with patients commonly switching between the two. Mean (standard deviation) annualized all-cause and EE-related healthcare costs in the follow-up period were $16,853 ($70,507) and $523 ($3659), respectively. Both all-cause and EE-related healthcare costs increased with LOTs.
Conclusions: Patients with EE are commonly treated with prescription PPIs; however, 19.0% of patients cycled through…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 158,347 participants or records.
