Abstract

BACKGROUND: Recent reports have demonstrated a decline in bacterial bloodstream infections (BSIs) following adherence to central line insertion practices; however, declines have been less evident for BSIs due to Candida species. METHODS: We conducted active, population-based laboratory surveillance for candidemia in metropolitan Atlanta, GA and Baltimore, MD over a 5-year period. We calculated annual candidemia incidence and antifungal drug resistance rates. RESULTS: We identified 3,848 candidemia cases from 2008-2013. Compared with 2008, candidemia incidence per 100,000 person-years decreased significantly by 2013 in both locations (GA: 14.1 to 9.5, p<0.001; MD: 30.9 to 14.4, p<0.001). A total of 3,255 cases (85%) had a central venous catheter (CVC) in place within 2 days before the BSI culture date. In both locations, the number of CVC-associated cases declined (GA: 473 to 294; MD: 384 to 151). Candida albicans (CA, 36%) and Candida glabrata (CG, 27%) were the most common species recovered. In both locations, the proportion of cases with fluconazole resistance decreased (GA: 8.0% to 7.1%, -10%; MD: 6.6% to 4.9%, -25%), while the proportion of cases with an isolate resistant to an echinocandin increased (GA: 1.2% to 2.9%, +147%; MD: 2.0% to 3.5%, +77%). Most (74%) echinocandin-resistant isolates were CG; 17 (<1%) isolates were resistant to both drug categories (multidrug resistant [MDR], 16/17 were CG). The proportion of CG cases with MDR Candida increased from 1.8% to 2.6%. CONCLUSIONS: We observed a significant decline in the incidence of candidemia over a five-year period, and increases in echinocandin-resistant and MDR Candida. Efforts to strengthen infection control practices may be preventing candidemia among high-risk patients. Further surveillance for resistant Candida is warranted.

  • Findings from EIP surveillance data have indicated a decrease in overall candidemia incidence in their longest-running surveillance sites of Atlanta, GA, and Baltimore, MD, with the incidence of all species decreasing except C. tropicalis.

    “Findings from EIP surveillance data have indicated a decrease in overall candidemia incidence in their longest-running surveillance sites of Atlanta, GA, and Baltimore, MD, with the incidence of all species decreasing except C. tropicalis [8].”

    From Invasive candidiasis species distribution and trends, United States, 2009-2017 (2021) · cites this paper as [8]

    The Abstract reports declining overall candidemia incidence in both Atlanta and Baltimore. The “Changes in species distribution” section says species-specific incidence decreased in both locations except for C. tropicalis in Atlanta, where it increased 4%; the claim omits that the exception applies only to Atlanta. (LLM, conf=0.87)

  • Active population-based surveillance showed the incidence of candidemia decreased from 2008 to 2017 across multiple US sites, with a coincident increase in the incidence of invasive candidiasis from non-blood sources, including abdominal sterile sites, from 2009-2017.

    “A more nuanced assessment using data from active population-based surveillance showed the incidence of candidemia decreased from 2008 to 2017 across multiple US sites,25,27,35 with a coincident increase in the incidence of IC from non-blood sources, including abdominal sterile sites, from 2009–2017.34”

  • In population-based surveillance performed in the metropolitan areas of Atlanta, Georgia, and Baltimore, Maryland, candidemia incidence (primarily among adults) increased 10%-40% from the early 1990s and the late 2000s, which was followed by more recent reports of decreases in these areas.

    The Changes in Incidence Rates section (page unavailable) reports substantial declines among infants in Atlanta and Baltimore from 2008 to 2013. It does not establish that those declines had occurred by the late 2000s. The early-1990s statement is attached to a different citation. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
