Abstract
Background
Invasive candidiasis (IC) including candidemia and deep-seated candidiasis is associated with up to 50 % overall mortality and up to $80,000 in attributable cost (2015 US$). Rapid diagnostic tests (RDTs) for Candida have been developed. However, whether RDTs along with real-time decision support translate to better attainment of stewardship goals—improve clinical outcomes, minimize unintended consequences of antifungal use, and reduce healthcare costs—is unknown. The purpose of this systematic review was to provide an up-to-date review of recently published studies that have assessed how RDTs for IC impact attainment of these goals.
Methods
Three electronic bibliographic databases were searched using a pre-defined search strategy evaluating the impact of RDTs for IC on attainment of antifungal stewardship goals. Quality assessments were performed by two reviewers using established study methodology metrics.
Results and Conclusions
Eight studies were identified of which five had sufficient information to be included in the review. Despite the limitations of the various studies and the different methodologies employed, the studies all produced similar conclusions. Compared to conventional methods and baseline stewardship activities, the integration of RDTs for IC and real-time decision support, mainly through antifungal stewardship, was associated with decreased mortality, more optimal use of antifungals, and reduced healthcare costs. However, larger clinical studies are needed to confirm these trends.

This open-label randomized controlled trial suggested that electronic templated comments can be used to communicate results of a rapid diagnostic test and deliver straightforward recommendations to clinicians, such as discontinuing treatment of contaminants and escalating therapy in patients with positive blood cultures. This was the first study to show that real-time antifungal stewardship is not the only effective form of support that can aid clinicians in acting on the results of a rapid diagnostic test.
