Abstract

Background: Dyspepsia is among the most common complaints evaluated by gastroenterologists, but there are few studies examining its current epidemiology, evaluation, and costs. We examined these issues in a large managed care system in the Southwestern United States.

Methods: We conducted a retrospective case-control analysis of adults with incident dyspepsia or a Helicobacter pylori-related condition in years 2006 through 2010 using utilization data. Medical record abstraction of 400 cases was conducted to obtain additional clinical information.

Results: A total of 6989 cases met all inclusion and exclusion criteria. Women had a substantially higher risk of dyspepsia than men (14 per 1000 per year vs 10 per 1000; p < .001), and the incidence of dyspepsia increased with age such that persons in their seventh decade had almost twice the risk of those aged 18-29. Hispanic persons had a significantly higher risk of dyspepsia and positive H. pylori testing. Dyspepsia cases had a higher prevalence of other chronic comorbidities than their matched controls. Dyspepsia patients had healthcare costs 54% higher than controls even before the diagnosis was made, and costs in the initial diagnostic period were $483 greater per person, but subsequent costs were not greatly affected. Among those aged 55 and younger, the "test and treat" approach was used in 53% and another 18% had an initial esophagogastroduodenoscopy, as compared to 47 and 27%, respectively, among those over the age of 55.

Conclusions: Women and older adults have a higher incidence of dyspepsia than previously appreciated, and Hispanics in this region also have a higher risk. Current guidelines for dyspepsia evaluation are only loosely followed.
