Abstract

This case study describes the use of SAS technology in streamlining cross-sectional and retrospective case-control studies in the exploration of the co-morbidity of depression and gastrointestinal disorders. Various studies in Europe and America have documented associations between irritable bowel syndrome and psychological conditions such as depression and anxiety disorders; however, these were observational studies. Because it is impossible to randomize symptoms, it is difficult to isolate patients with these co-morbidities for randomized trials. Therefore, studies will continue to use observational data. In this study, all steps are conducted electronically in a rapid development environment provided by SAS technology. In addition, it examines the potential rate of health-care utilization particularly for GI disorders among individuals with depressive symptoms and anxiety disorders. We find that the proportion of patients with gastrointestinal problems and psychological disorders is typically higher than the proportion of patients with only gastrointestinal problems.
