A significant portion of patients already known to be colonized or infected with Methicillin-Resistant Staphylococcus aureus (MRSA) may not be identified at admission by neighboring hospitals.
We utilized data from a Regional Health Information Exchange to assess the frequency that patients known to have MRSA at one healthcare system are admitted to a neighboring healthcare system unaware of their MRSA status. We conducted a retrospective, registry trial from January 1999 through January 2006 involving three healthcare systems in central Indianapolis, representing six hospitals.
Over one year, 286 unique patients generated 587 admissions accounting for 4,335 inpatient days where the receiving hospital was not aware of the prior history of MRSA. The patients accounted for an additional 10% of MRSA admissions received by study hospitals over one year and over 3,600 inpatient days without contact isolation.
Information exchange could improve timely identification of known MRSA patients within an urban setting.
很大一部分已知已定植或感染耐甲氧西林金黄色葡萄球菌（MRSA）的患者在入院时可能未被周边医院识别出来。
我们利用区域卫生信息交换的数据来评估在一个医疗系统中已知患有MRSA的患者被收治到对其MRSA状况不知情的周边医疗系统的频率。我们进行了一项回顾性登记试验，时间从1999年1月至2006年1月，涉及印第安纳波利斯市中心的三个医疗系统，代表六家医院。
在一年多的时间里，286名独特患者产生了587次住院，共计4335个住院日，而接收医院并不知晓其先前的MRSA病史。这些患者占研究医院一年多来接收的MRSA住院患者的额外10%，以及超过3600个无接触隔离的住院日。
信息交换可以改善城市环境中已知MRSA患者的及时识别。
