Abstract

Nosocomial infection is important in the management of the nursing care and has been found to be related with the airborne microbes contamination. The purpose of this study is to identify the differences of the airborne microbes between hospitals, nursing units, days and times and to identify the difference in the types of microorg-anisms between hospitals, nursing units, days and times. This study was conducted from May 25, to July 10, 1981, according to R. Koch's methods for quantative samplings of airborne microbes and the results of this study were reviewed in a statistical method. The following conclusions were obtained: 1. There was a significant difference in the types of airborne microbes between 8 hospitals (F=5.0491, P<0.01) 2. There was a significant difference in the types of airborne microbes between surgical, medical, nursery, I.C.U., operating theatre and outpatient nursing unit, (F=2.1764, P<0.05) 3. There was not a significant difference in the types of airborne microbes between Monday, Thrusday and Saturday (F=1.6365, P>0.05) 4. There was a significant difference in the types of airborne microbes between AM 7 : 00, AM 11: 00 and PM 3 : 00. (F=7.2951, P<0.01) 5. 4061 colonies were divided into more 48 types and the classification was as follows. gram positive cocci (2024 colonies) 49.3% gram positive bacillus (1211 colonies) 29.8% gram negative bacillus (577 colonies) 14. 2% fungus (200 colonies) 4.9% gram negative cocci (41 colonies) 1.0% other's (8 colonies) 0.3% 6. There was a significant difference of airborne microbes between 8 hospitals. (F=7.7943, P<0.01) 7. There was not a significant difference of airborne microbes between 6 nursing units. (F= 1.8461, P>0.05) outpatient nursing unit : 12.6 colonies surgical nursing unit: 10.4 colonies Medical nursing unit : 9.8 colonies nursery nursing unit: 9.4 colonies operating theatre nursing unit: 8.2 colonies Intensive care nursing unit: 7.8 colonies 8. There was not a significant difference of airborne microbes between Monday, Thursday and Saturday. (F=1.4371, P>0.05) Saturday : 11.0 colonies Monday : 9.1 colonies Thursday : 9,1 colonies 9. There was a significant difference of airborne microbes between A.M. 7 : 00, A.M. 11 : 00 and P.M. 3 : 00 (F=7.6658, P<0.05) P.M. 3 : 00 : 12.2 colonies A.M. 11 : 00 : 10.0 colonies A.M. 7 : 00 : 7.1 colonies.
