초록

본 연구는 다제내성균 환자가 사용한 병실 환경에 대한 환경관리 평가 방법 중 미생물 배양검사와 Adenosin Triphosphate Bioluminescence 방법을 이용하여 오염도를 파악 한 후 환경소독제를 이용하여 소독효과를 평가하고자 시도되었다. 환경표면은 다제내성균으로 격리된 환자병실을 대상으로 하였다. 검체채취는 인퓨전펌프, IV 폴대, 상두대, 침대난간, 키보드 혈압기 커프 5곳을 실시하였고 소독 전, 소독 직후, 소독 후 5분 후 ATP와 미생물배양검사를 실시하였다. 연구결과 Infusion pump의 환경표면이 소독·후 오염도가 통계적으로 유의하게 감소하였다. 또한 IV 폴대, 침상난간, 키보드는 소독 전후 균 검출이 감소하였다. 즉 정기적인 환경표면소독은 환자에게 감염으로부터 안전한 환경을 제공할 수 있다. 따라서 향후 다기관을 대상으로 소독제의 지속성 등을 평가하여 환경표면 소독방법, 소독주기 등의 지침을 마련하는 것이 필요하다.

This study was carried out to evaluate the effects of disinfection using environmental disinfectant after having assessed the extent of contamination through microbial culture testing and the Adenosine Triphosphate Bioluminescence method among the environmental management evaluation methods used for the environment in the hospital ward of patients infected by multidrug-resistant organisms. This study was conducted with the patient wards isolated due to multidrug-resistant organisms as the environmental surface. Specimens were collected from five locations including infusion pumps, IV poles, bedside cabinets, bed railings, keyboards, and blood pressure measurement cuffs. ATP and microbial culture testing were executed prior to, immediately after, and five minutes post-disinfection. According to the result contamination of the infusion pumps was statistically significantly reduced after disinfection. In addition, the bacteria before and after disinfection reduced in IV pole, bed railing, and keyboard. That is, regular environmental surface disinfection can provide safer environments to patients against infection. Therefore, it is necessary to establish guidelines including disinfection methods and intervals for environmental surfaces by evaluating the persistence of disinfectants at various institutions in the future.
