Survey
Among the 51 practitioners surveyed, 36% were performing routine echo and 22% self-reported performing routine abdominal imaging. After education, no respondents planned to routinely do echo or abdominal imaging. All but 1 respondent planned to change their practice for evaluation of fungemia patients based on the presentation (eFigure 1).
Baseline Data
Over the 23-month period from January 1, 2016 to November 19, 2017, there were 21 episodes of fungemia, 18 of which occurred in patients on the pediatric gastroenterology service (2 of the 18 were transplant recipients). For the 18 episodes on this service, abdominal imaging and echo were done 100% of the time, with 0 positive findings (eFigure 2).
Of those 18 episodes, the average age was 4.6 years, with two-thirds of the population being male. There were 3 patients with multiple episodes that accounted for 8 of the episodes (3, 3, and 2 episodes each). Fever was the most common presenting complaint. The most common organism was Candida parapsilosis (6 of the 18 episodes). All episodes but one involved a central line, and all central lines were removed when present except for one case. Of the risk factors, 3 episodes occurred in neutropenic patients, and for 1 episode the patient had a questionable history of fungal endocarditis (and was on fungal prophylaxis). There were no patients with recent cardiac/urogenital surgery or prior fungal balls. No episodes had clinical symptoms suggestive of fungal endocarditis or fungal balls.
Post-Intervention Data
Over the subsequent 17-month period (November 11, 2017 to April 3, 2019), there were 13 episodes of candidemia. There were no episodes of Cryptococcus fungemia. Seven episodes occurred in patients on the pediatric gastroenterology service (2 of the 7 occurred in transplant recipients). Abdominal imaging was done in 3 of these episodes (43%), and in 2 of these 3 episodes, imaging was done at an outside institution prior to arrival, with no positive results (eFigure 2).
Echocardiography was done 57% of the time (n = 4), with echo being done at an outside institution prior to arrival half of the time (n = 2), with no endocarditis identified. The cases of abdominal imaging and echo done at outside institutions prior to arrival were not impacted by the countermeasures. Excluding those 2 patients who had both abdominal imaging and echocardiography done prior to arrival, the overall rate of imaging (both abdominal imaging and echo) done after countermeasures were instituted was 30% (Figure 3).
