Objective : To evaluate bactericidal efficacy of alcohol solution during actual use and typical storage conditions in community
hospital and health centers.
Material and Method: The alcohol samples were collected immediately after the first bottle-opening (day 0) and on day 3, 7,
14, 21 and 30 from 10 stations in hospital and community health centers in Pone-na-kaew district, Sakon Nakhon province,
Thailand, during May-July 2011. Bactericidal efficacy of these samples against Staphylococcus epidermidis, Staphylococcus
aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae was evaluated. Ethanol concentration was
quantified by a gas chromatography method.
Results : Bactericidal efficacy of the alcohol samples still remained on day 30 with ethanol concentration range of 60.91-
65.99% v/v.
Conclusion : This finding should be considered as a cost-benefit model for using alcohol solution in community hospital and
health centers.
