Review of medical records revealed that, of 190 intravascular catheters sent for culture during the study period, 50 were positive. Of these 50, 11 (22%) were sent for culture as a routine procedure without special clinical indications. Of the remaining 39 cultures, only 11 (28%) had clinical impact in the patient's management. Ten of the 50 therapeutic interventions were inappropriate. Restricting cultures to patients who may have catheter-related infection is likely to lead to significant cost savings.
病历审查显示，在研究期间送检培养的190根血管内导管中，有50根培养结果呈阳性。在这50根阳性导管中，有11根（22%）是作为常规程序送检培养的，并无特殊临床指征。在其余39次培养中，只有11次（28%）对患者的治疗产生了临床影响。50次治疗干预中有10次是不恰当的。将培养限制在可能有导管相关感染的患者中，可能会大幅节省成本。
