In order to achieve simultaneously a higher quality of hospital care and cost-containment, an objective assessment of alternative systems for surveillance of hospital infections is needed in our country. This assessment will allow to make a rational choice of the system to be used at each hospital.
719 patients admitted to a Vascular Surgery ward were studied. Sensitivity, specificity, and predictive values for a selective system of surveillance of nosocomial infection (NI) were assessed. This selective system attempted to contain costs by means of limiting the revision of records to those patients who presented fever, prescription of antibiotics after admission or who required laboratory cultures. In this selective method charts revision was retrospectively performed by nurses.
A low sensitivity (50.9%) and acceptable values for specificity and predictive values were found.
Although this selective method requires only 20% of the reference method's time, its association with an important reduction in sensitivity precludes its systematic use and confines it eventually to low risk wards.
为了同时实现更高质量的医院护理和成本控制，我国需要对医院感染监测的替代系统进行客观评估。该评估将有助于各医院合理选择要使用的系统。
对719名入住血管外科病房的患者进行了研究。评估了一种医院感染（NI）选择性监测系统的敏感性、特异性和预测值。该选择性系统试图通过将记录审查限制在出现发热、入院后使用抗生素或需要实验室培养的患者身上来控制成本。在这种选择性方法中，护士对病历进行回顾性审查。
发现敏感性较低（50.9%），特异性和预测值可接受。
虽然这种选择性方法只需要参考方法20%的时间，但其与敏感性的显著降低相关，这排除了其系统使用的可能性，并最终将其限制在低风险病房。
