Abstract

This study examines the adoption of a new preventive treatment for HIV called preexposure prophylaxis (PrEP) in a nation-wide network of US physicians. We compare the structure of these networks across nine multi-state census regions, and assess geographic variations in network structure. Within these networks, we measured the adoption threshold associated with physician adoption of PrEP. The low threshold values that we observe are consistent with the hypothesis that slow PrEP adoption is the result of a lack of knowledge and exposure among physicians. Regression results demonstrate the mix of market, epidemiological, and socio/cultural factors that shape adoption thresholds.

评估在全国范围内的医生网络中采用 PrEP 的动态变化

本研究探讨了美国全国范围内的医生网络采用一种名为 "暴露前预防"（PrEP）的新型艾滋病预防疗法的情况。我们比较了九个多州人口普查地区的网络结构，并评估了网络结构的地域差异。在这些网络中，我们测量了与医生采用 PrEP 相关的采用阈值。我们观察到的低阈值与以下假设相符：PrEP 的缓慢采用是医生缺乏知识和接触的结果。回归结果表明，市场、流行病学和社会/文化因素共同影响着采用阈值。

期刊介绍： Social Networks is an interdisciplinary and international quarterly. It provides a common forum for representatives of anthropology, sociology, history, social psychology, political science, human geography, biology, economics, communications science and other disciplines who share an interest in the study of the empirical structure of social relations and associations that may be expressed in network form. It publishes both theoretical and substantive papers. Critical reviews of major theoretical or methodological approaches using the notion of networks in the analysis of social behaviour are also included, as are reviews of recent books dealing with social networks and social structure.
