Demographics
The analysis included 74/75 patients which had at least one respiratory culture in their medical record. Demographic data are presented in Table 1 including comparison between children who ever had a MDRO-positive culture and those who never had an MDRO recovered from culture throughout the study (MDRO-negative). All the participants had tracheostomies and 69 (93%) of them were on chronic mechanical ventilation. Our patient population was predominately female and Caucasian. They mostly come from rural, small town, and suburban areas. The most common primary diagnosis was neuromuscular disease (n=45, 61%) which included neurologic, cerebral palsy, secondary paralysis, myopathies, and muscular dystrophies. There was no significant difference between the baseline demographics of the MDRO-positive and MDRO-negative participants.
