In addition to EHR status, a number of independent variables measuring various organizational demographic data were collected. Organizational questions included practice type, practice ownership, practice size, number of practice locations, physician’s specialty, HIT ownership, and HIT support. Practice type refers to whether the physician practices in an independent practice or as part of a medical group component of a hospital or health system. The variable ownership is differentiated from HIT ownership; the former is concerned with who owns the practice, and the latter addresses the ownership of the information technology the practice uses. The specific operationalization of each variable used in the current study is summarized in Table 1.
