We present a mesoergonomic approach to the early detection of neonatal sepsis, analyzing clinical data for 4999 patients from a neo-natal intensive care unit to predict positive culture results. The Apgar score at birth predicted positive results. For neonates with poor and intermediate Apgar scores, culture results for monitored infants were more likely to be positive than those for unmonitored infants. Thus, the medical staff tended to monitor infants who eventually had a greater chance for positive test results. A cost-effectiveness analysis indicated that for infants with high Apgar scores, the physician should decide whether to obtain a blood culture, based on the patient's characteristics. For infants with lower Apgar scores, it may be advisable to obtain a blood culture whenever one decides to monitor a neonate. The study demonstrates that staff decisions regarding a patient can serve as input for further clinical decision-making.

我们提出了一种早期检测新生儿败血症的人体工程学方法，分析了来自新生儿重症监护病房的 4999 名患者的临床数据，以预测阳性培养结果。出生时的 Apgar 评分预测了阳性结果。对于 Apgar 评分较差和中等的新生儿，受监测婴儿的培养结果比未受监测婴儿的培养结果更可能呈阳性。因此，医务人员倾向于监测最终有更大机会获得阳性检测结果的婴儿。一项成本效益分析表明，对于 Apgar 评分高的婴儿，医生应根据患者的特征决定是否进行血培养。对于 Apgar 评分较低的婴儿，建议在决定监测新生儿时进行血培养。
