Abstract
Nursing home have been found to play a significant role in the spread of Antimicrobial Resistant Organisms (AMROs). However, only few reports have elucidated the isolation of resistant bacteria and risk factors for the carriage such bacteria in these facilities. This study examined the situation of the carriage of AMROs in a special unit-type nursing home (Facility A). The residents of Facility A mainly live in their own rooms. The study also analyzed the risk factors of bacterial carriage among the residents of Facility A based on their attributes. We obtained consent for study participation from 28 residents. Certain resistant bacteria were detected in 10 participants (35.7%). Of these bacteria, Methicillin-resistant Staphylococcus aureus (MRSA) was detected in one participant (3.6%) and glucose non-fermenting bacteria, which grew in a culture medium selective for Extended-Spectrum β-lactamase (ESBL), were detected in two participants (7.1%). The bacterial carriage rate among participants of Care Level 4 or above was 53.8%, which was higher than that of participants of Care Level 3 or below (20.0%). No statistically significant difference (p = 0.06, chi-square test) was found between the two groups. Additionally, a comparison of bacterial carriage rates between participants who require assistance for everyday activity and those who do not revealed that the rates were higher in those who required assistance for eating, excretion, and moving between the bed and wheelchair. The difference observed was not significant. This study did not find significant difference for any risk factors. However, we deem that future studies are needed in larger cohorts and in a larger number of facilities. In doing so, the characteristics of facilities should be considered.
