Duration of colonization with and risk factors for prolonged carriage of multidrug resistant organisms among residents in long-term care facilities

Background Residents of long-term care facilities (LTCFs) colonized with multidrug resistant organisms (MDROs) are often placed under contact isolation to ensure appropriate infection control. This isolation may reduce opportunities for rehabilitation and social stimuli and may also increase medical costs. However, the number of previous studies investigating the duration of colonization in LTCFs is limited. This study was conducted to determine the duration of colonization and risk factors for prolonged carriage of MDROs among residents of a LTCF.
