Little is known about the opportunities for a community clinical data exchange network to influence patient care. Rates of patient "cross-over" among different institutions can provide one estimate of the additional value such systems have over unconnected, independent institutional electronic medical records. The Indiana Network for Patient Care (INPC) represents such a system, involving a collaboration of central Indiana hospitals to improve patient care. During a one year study period, 288,696 patients made 471,640 Emergency Department (ED) visits within the INPC collaboration -- accounting for 92% of all Indianapolis ED visits. Overall 25% of the patients with more than one visit also visited one of the other five hospital systems, accounting for 19% of all visits. Our results help clarify the expected frequency within one large metropolitan area that ED patients could obtain direct benefit from a community clinical data exchange network.
关于社区临床数据交换网络影响患者护理的机会，人们了解甚少。不同机构之间患者“交叉就诊”的比率可以提供一种估计，即此类系统相对于未联网的独立机构电子病历所具有的额外价值。印第安纳州患者护理网络（INPC）就是这样一个系统，它涉及印第安纳州中部各医院的合作，旨在改善患者护理。在为期一年的研究期间，288,696名患者在INPC合作范围内进行了471,640次急诊科（ED）就诊，占印第安纳波利斯所有ED就诊的92%。总体而言，有多次就诊经历的患者中有25%还就诊于其他五个医院系统之一，占所有就诊的19%。我们的研究结果有助于明确在一个大都市地区内，急诊科患者能够从社区临床数据交换网络中直接受益的预期频率。
