Quaternary Ammonium Compound Disinfectant Efficacy Test on The Patients’ Environment in dr. Cipto Mangunkusumo General Hospital

The increasing prevalence of hospital-acquired infection continues to be a global concern until today. The purpose of this study is to determine the efficacies of Caviwipe® and 70% alcohol tissue in the prevention of hospital-acquired infection. This experimental study was conducted on 36 equipment samples in dr. Cipto Mangunkusumo Hospital during April–August 2015. A total of 144 surface samples were collected before and after the disinfection process by both the disinfectants. The sample equipment used and placed in the agar plate for a short period of time; the plates were then incubated. The colony numbers of grown bacteria and fungi were calculated. The data were numerically reported as the microbial colony count. Data were analyzed by using SPSS for Windows. Paired t-test was used for the statistical analysis. The mean colony counts before disinfection by 70% alcohol tissue and Caviwipe® were 11.75 and 17.58, respectively. Meanwhile, the average colony counts after disinfection with 70% alcohol tissue and Caviwipe® were 0.138 and 0.222, respectively. Statistical analysis showed no significant difference between the mean of the colony count before and after disinfection with both disinfectants (p>0.05). Separately, a significant difference of colony count between before and after the disinfection process for each disinfectant was seen (p<0.05). The mean reduction in the colony counts after disinfection by both disinfectants indicates that there is no significant difference (p>0.05) in the efficacies between the Caviwipe® and 70% alcohol tissue in reducing the amount of bacteria and fungi present on the surfaces of the equipment placed close to the patients in a hospital environment.
