当病人从一家医院转到另一家医院时，控制危及生命的感染，如耐甲氧西林金黄色葡萄球菌（MRSA）的努力可能会变得复杂。利用加利福尼亚奥兰治县所有医院的详细计算机模拟模型，我们探索了当医院联合对所有入院患者进行MRSA检测并采取措施限制检测阳性患者之间的传播时的影响。这些程序被称为“接触隔离”，规定了与感染患者接触的医护人员的预防措施，例如戴手套和穿长袍。我们的模拟表明，每家医院检测MRSA和实施接触者隔离程序的决定可能会影响所有其他医院的MRSA患病率。因此，我们的研究表明，医院之间的进一步合作，已经反映在一些有限的合作感染控制工作中，可以帮助个别医院实现比他们自己更好的感染控制。
Efforts to control life-threatening infections, such as with methicillin-resistant Staphylococcus aureus (MRSA), can be complicated when patients are transferred from one hospital to another. Using a detailed computer simulation model of all hospitals in Orange County, California, we explored the effects when combinations of hospitals tested all patients at admission for MRSA and adopted procedures to limit transmission among patients who tested positive. Called "contact isolation," these procedures specify precautions for health care workers interacting with an infected patient, such as wearing gloves and gowns. Our simulation demonstrated that each hospital's decision to test for MRSA and implement contact isolation procedures could affect the MRSA prevalence in all other hospitals. Thus, our study makes the case that further cooperation among hospitals which is already reflected in a few limited collaborative infection control efforts under way could help individual hospitals achieve better infection control than they could achieve on their own.
