Relationship between Information Technology Level and Triple Dimensions of Organizational Structure in the Hospitals of Tehran University of Medical Sciences

In the near future, no factor like Information Technology (IT) is able to change the structure of organization. In this research the effect of IT on triple dimensions of organization structure includes complexity, formalization, and centralization was evaluated. In this cross-sectional and analytical-descriptive research, staffs from in ten study hospitals that had administrative posts and were IT specialists were studied. These ten hospitals were selected randomly. All data are collected by observation, interview and questionnaire (Rabinz and CSF). We analyze data using STATA (900), Pearson correlation linear and multiple regression tests. There was significant relationship between the overall status of IT and centralization (P = 0.01) and formalization (P = 0.06).In most of the cases the five dimensions of IT (including network, hardware, software, staff and utilization) had significant effect on utilization with formalization from the triple dimensions of organization structure. Though the influence of IT was not in a way that leads to fundamental change in the structure of the studied hospitals but it seems that IT had significant effect on utilization with formalization dimensions of organization structure.
