中文摘要
信息流通不畅会阻碍协调，可能导致医疗保健领域的次优决策。我们考察了一项大规模健康信息整合政策的效果。我们利用芬兰全国电子处方系统在四年间的交错（分批）实施以及处方层面的行政数据。结果显示，平均而言，该政策对有害药物联合开具概率没有可辨别的影响；但异质性分析表明，这一概率在农村地区下降了35%。这一大幅下降是由不同医生之间以及全科医生开具的具有相互作用的处方所驱动的。因此，信息整合能够改善医生相互依赖决策的协调。
Abstract
Poor information flows hamper coordination, potentially leading to suboptimal decisions in health care. We examine the effects of a large-scale policy of health information integration. We use the staggered adoption of a nationwide electronic prescribing system over four years in Finland and prescription-level administrative data. Our results show no discernible effect on the probability of co-prescribing harmful drugs on average, but the heterogeneity analysis reveals that this probability reduces in rural regions, by 35 percent. This substantial reduction is driven by interacting prescriptions from different physicians and generalists. Information integration can therefore improve the coordination of physicians' interdependent decisions.
