The Impact of Information Technology on the Diffusion of New Pharmaceuticals
研究美国医生获取决策相关药物数据库的变化如何影响处方决策，发现使用数据库的医生更倾向开仿制药、更快采用新仿制药且处方更多样化，对医疗成本有重要影响。
Do information differences across US physicians contribute to treatment disparities? This paper uses a unique new dataset to evaluate how changes in physician access to a decision-relevant drug database affect prescribing decisions. Our results indicate doctors using the reference have a significantly greater propensity to prescribe generic drugs, are faster to begin prescribing new generics, and prescribe a more diverse set of products. These results are consistent with database users responding primarily to the increased accessibility of non-clinical information such as pricing and insurance formulary data, and suggest improvements to physician information access have important implications for aggregate healthcare costs.
