| Abstract;This paper investigated the distribution of environmental bacteria during the 13-year-period after Iwate Prefectural Central Hospital moved to a new building. (1) The change in airborne bacteria during the 13-year-period was found to be virtually the same as when the building was new. (2) A reduction in airborne bacteria through the use of HEPA filters was observed. (3) Within the hospital and depending on the season, the number of airborne bacteria fluctuated. (4) The detection ratios of airborne bacteria during the 13-year-period hovered in the following ranges: Gram Positive Coccus (GPC): 75.9 to 77.3%; Gram Positive Bacillus (GPB): 17.3 to 18.3%; Neisseria spp.: 0.2 to 1.3%; Gram Negative Rod (GNR): 2.9% to 4.8%; and mycetes: 1.2%. (5) With respect to the number of airborne bacteria detected, assigning a semi-sterile room as 1.0, the nurse's center registered 4.81 times this number and general wards registered 7.22 times this number. (6) The installation of HEPA filters is an effective way of reducing bacteria in the hospital. (7) Cooperation with epidemiologists is needed for improved in-hospital surveillance of airborne bacteria. (author abst.) |
