Clinicians therefore commonly rely on presumed species-level fluconazole susceptibility to guide initial therapy. Whether these presumed susceptibility categories identify clinically distinct patient populations with different treatment patterns and outcomes remains uncertain.<\/jats:p>\n                  <jats:p>We conducted a retrospective cohort study using TriNetX Research Network (May 2017\u2013November 2023) including adults with PCR-identified candidemia. Patients were categorized as presumed fluconazole susceptible (FS) (Candida albicans, C. parapsilosis, and C. tropicalis) or presumed fluconazole nonsusceptible (FNS) (Nakaseomyces glabratus, Pichia kudriavzevii, and C. auris). Clinical characteristics, antifungal treatment patterns, and 90-day all-cause mortality were evaluated using inverse probability of treatment weighting (IPTW) and Cox proportional hazards models.<\/jats:p>\n                  <jats:p>Among 1171 patients, 43% were categorized in the FNS group. Compared with the FS group, patients in the FNS group were older, had greater comorbidity burden, and more frequently received echinocandins, whereas azole exposure was more common in the FS group. Despite similar crude 90-day mortality (23.9% vs 23.3%), IPTW-adjusted analysis demonstrated lower survival among patients in the FS group (adjusted hazard ratio\u00a01.41, 95% confidence interval 1.09\u20131.82, P = .009). Within-group analyses identified variables independently associated with mortality.<\/jats:p>\n                  <jats:p>Species categorized as presumed FNS accounted for nearly half of PCR-identified candidemia cases and were associated with clinically distinct patient populations characterized by different baseline characteristics and mortality associations.
