Hygienic Investigation on Cleanness of Environment in Intravenous Medicine Admixture Service Center of Hospitals

Objectives To investigate the hygienic conditions and influencing factors on the cleanness of environment in the intravenous medicine admixture service center of hospitals, so as to provide scientific basis for administration and surveillance.

Methods The investigation was conducted in 106 cleaning rooms of 12 hospitals and the initial inspection result were analyzed.

Results The total qualified rate of 106 cleaning rooms was 69.8%; the qualified rate of permitted suspended particles concentration was the lowest (79.2%); the qualified rate of clean rooms at static state was lower than that at newly built state (χ²=13.391, P=0.000); the qualified rate of cleaning liquor rooms for liquid preparation was lower than that for clean auxiliary rooms (χ²=4.809, P=0.028); the qualified rate of cleaning liquor rooms with negative pressure was lower than those with positive pressure(P=0.029); no statistically significant difference was shown among different auxiliary rooms (χ²=3.622, P=0.164).

Conclusions The administration and surveillance on the cleanness of liquor rooms in hospitals for intravenous liquid medicine preparation should be strengthened. The investigation on cleaning rooms at static state should be concerned, and focused on liquor rooms with negative pressure. The concentration of suspended particles was the main factor influencing the qualified rate.
