Antimicrobial resistance patterns among urinary isolates from long-term care residents in Canada: findings from an AMRNet pilot

AMRNet surveillance of urinary isolates from long-term care residents in five Canadian provinces (2016–2024) found 98% of isolates from patients aged ≥60, with E. coli at 51%.

• Why it matters: Canadian long-term care antimicrobial resistance data have been limited, despite residents being older, chronically ill, and often exposed to antimicrobials.
• What they did: Lab-based susceptibility data from public and private laboratories were analyzed by using the first isolate per patient per species per calendar year, with urinary isolates summarized by age, sex, species, and AWaRe categories.
• The result: Non-susceptibility was common in key pathogens: E. coli showed 44% non-susceptibility to fluoroquinolones and 18% to third generation cephalosporins, while K. pneumoniae had 56% to nitrofurantoin.
