Description
Summary:Objectives (1) To identify the cost‐driving factors of health expenditure in inflammatory bowel disease (IBD), (2) to determine the effect of different cost‐sharing levels on outpatient visits and (3) to determine the effect of different cost‐sharing levels on medication adherence among patients with IBD. Method This was a retrospective, longitudinal study in which data were collected from 1999 to 2013 using the Medical Expenditure Panel Survey. The study sample included all patients who had IBD, were at least 18 years old, and had insurance. A comprehensive list of demographic factors was assessed to identify cost‐driving factors associated with high level of expenditure in IBD. Two logistic regression models were built to examine the association between outpatient cost sharing and number of outpatient visits, and between prescription cost sharing and medication adherence. Statistical significance was evaluated at P
