Information Integration, Coordination Failures, and Quality of Prescribing
研究了芬兰全国电子处方系统分阶段实施对有害药物联合处方概率的影响，发现农村地区该概率降低35%，表明信息整合能改善医生间协调。
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.
