This study fills a gap in literature by providing contemporary real-world evidence on the prevalence of patients with gastroesophageal reflux disease (GERD), Barrett esophagus (BE), and Barrett esophagus-related neoplasia (BERN) and their upper endoscopy utilization patterns in the United States. A retrospective cohort study design was used: adults with GERD, nondysplastic Barrett esophagus (NDBE), and BERN (indefinite for dysplasia [IND], low-grade dysplasia [LGD], high-grade dysplasia [HGD], or esophageal adenocarcinoma [EAC]) were identified from the MarketScan databases (January 01, 2015-December 31, 2019). For each disease stage, prevalence of adults in commercial claims by calendar year, annual number of upper endoscopies per patient and time between upper endoscopies were reported. In 2019, in commercial claims (N = 12,363,227), the annual prevalence rate of GERD was 13.7% and 0.70% for BE/BERN, among which, 87.1% had NDBE, 6.8% had IND, 2.3% had LGD, 1.0% had HGD, and 2.8% had EAC. From 2015-2019, the study included 3,310,385 patients with GERD, 172,481 with NDBE, 11,516 with IND, 4332 with LGD, 1549 with HGD, and 11,676 with EAC. Annual mean number of upper endoscopies was 0.20 per patient for GERD, 0.37 per patient for NDBE, 0.43 for IND, 0.58 for LGD, and 0.87 for HGD. Median time (months) to second upper endoscopy was 38.10 for NDBE, 36.63 for IND, 22.63 for LGD, and 11.90 for HGD. Upper endoscopy utilization increased from GERD to BE to BERN, and time between upper endoscopies decreased as the disease stage progressed from BE to BERN, with less frequent utilization in BERN than what would be expected from guideline recommendations for surveillance.
