Syed AR, et al. - In this cross-sectional population-based study, researchers established the epidemiological features and documentation of diagnostic workup for gastroparesis (GP). They used the Explorys Platform to determine the prevalence of GP in a large and diverse population highly representative of the US population and to investigate the diagnostic approach of GP. Information gathered were individual characteristics from electronic medical records (EMRs) included age, ethnicity/race, sex, diagnostic report for esophagogastroduodenoscopy (EGD) and gastric emptying study (GES). In total, 43,827,910 medical records were surveyed (1999 to 2014), of which 69,950 had a diagnosis of GP, yielding an overall prevalence of 0.16%. GP was confirmed by both diagnostic tests in 16.8%, 14.0%, and 13.2%, respectively, for patients with T1DM, T2DM, or idiopathic GP. The estimated rates of prevalence of GP in T1DM and T2DM show that GP is not a common clinical complication in these populations. There was no evidence of conclusive diagnostic testing (EGD and/or GES) in the majority of EMRs that suggested GP diagnosis.
