In order to study the relationship between physician networks and utilization of a computer-based hospital information system (HIS), blockmodel analysis and multidimensional scaling were used to analyze and spatially represent the network of professional relations among 24 physicians in a private group practice. A blockmodel analysis of patient referrals, consultations, discussions, and on-call coverage identified four groups of physicians who share common locations and perform similar roles within the network. Investigation of the shared attributes of these groups supports this relational structure. The results suggest that the center-periphery model of diffusion of new ideas among professionals may be too simplistic. Instead, the communication network may involve multiple central cohesive subgroups of physicians who differentially initiate patient referrals and consultations with physicians in other subgroups. Network location was found to have a significant effect on the adoption and utilization of the HIS independently of background and practice characteristics of physicians. The results also suggest that adoption of an innovation and its implementation or utilization may involve separate processes that need to be differentiated in future research.
为了研究医师网络与基于计算机的医院信息系统（HIS）的使用之间的关系，运用块模型分析和多维标度法来分析并在空间上呈现一家私立集团诊所中24位医师之间的专业关系网络。对患者转诊、会诊、讨论及值班安排进行的块模型分析确定了四组医师，他们在网络中处于相同位置并履行相似职责。对这些组共享属性的调查支持了这种关系结构。结果表明，专业人员之间新思想传播的中心-外围模型可能过于简单。相反，通信网络可能涉及多个核心凝聚亚组的医师，他们以不同方式发起与其他亚组医师之间的患者转诊和会诊。研究发现，网络位置对HIS的采用和使用有显著影响，且独立于医师的背景和执业特征。结果还表明，创新的采用及其实施或使用可能涉及不同的过程，未来研究需要对其加以区分。
