to correlate surface cleaning and disinfection monitoring methods in two neonatal intensive care units and compare threshold values for adenosine triphosphate.
a correlational study with 864 assessments was conducted using adenosine triphosphate quantification, visual inspection, aerobic colony count, Staphylococcus aureus detection, and resistance testing before and after hygiene procedures.
in Unit A, correlations were found between colony count and Staphylococcus aureus on the counter (phase I; P=0.031) and between adenosine triphosphate and colony count in the incubator (phase II; P=0.001). In Unit B, a correlation was observed between adenosine triphosphate and colony count on the infusion pump (phase I; P=0.045). Threshold values for adenosine triphosphate were lower than 28 relative light units in Unit A and equal to or lower than 38 in Unit B.
variations were observed in the correlations and threshold values for adenosine triphosphate between the analyzed units.
关联两个新生儿重症监护病房的表面清洁与消毒监测方法，并比较三磷酸腺苷的阈值。
在卫生程序前后，采用三磷酸腺苷定量、目视检查、需氧菌落计数、金黄色葡萄球菌检测和耐药性测试进行了一项包含864次评估的相关性研究。
在A病房，在柜台处菌落计数与金黄色葡萄球菌之间存在相关性（第一阶段；P=0.031），在培养箱中三磷酸腺苷与菌落计数之间存在相关性（第二阶段；P=0.001）。在B病房，在输液泵上三磷酸腺苷与菌落计数之间观察到相关性（第一阶段；P=0.045）。A病房三磷酸腺苷的阈值低于28相对光单位，B病房则等于或低于38。
在所分析的病房之间，观察到三磷酸腺苷的相关性和阈值存在差异。
