This study sought to investigate the factors that led residents with IDU-associated diagnoses and procedures to seek care outside their home cities of Lawrence and Lowell, Massachusetts. Endocarditis diagnoses were found to be no different between hospitals in and out of Lawrence and Lowell, however, echocardiograms (CI = -0.19, -0.14; p-value = <0.001), skin and soft tissue infections (CI = 1.11, 1.23; p-value = <0.001), and irrigation and drainage procedures (CI = 0.15, 0.21; p-value = <0.001) were all found to be significantly different. These changes in hospital use highlight the need to account for patient-resident mobility during the creation of future similar studies.
