Rapid molecular testing for antimicrobial stewardship and solid organ transplantation
Abstract Background Several molecular platforms now exist for early detection of infectious pathogens. In this review, we present the currently available literature summarizing clinical outcomes using rapid diagnostic tests (RDTs) in the solid organ transplant (SOT) population. We also present potential benefits and drawbacks of these technologies for SOT patients. Methods We completed a PubMed search querying for 31 specific RDTs AND (“SOT”). We also queried PubMed for studies on RDT outcomes in the general population. References of the resulting relevant studies were reviewed and incorporated if the study population included at least one SOT patient. All culture specimen types were included. Only full‐text peer‐reviewed publications in English were examined. Results Our search yielded eleven studies. Across these studies, integrating RDTs with ASP intervention led to faster species identification and susceptibility results, faster time‐to‐optimal therapy, decreased hospital length‐of‐stay and costs, and decreased mortality. Potential drawbacks of RDTs in the SOT population included: overdiagnosis due to increased sensitivity (i.e., Clostridium difficile), decreased yield of tests for respiratory pathogens, and lack of identification of important pathogens in this population such as, Aspergillus species. Conclusions Although there is a scarcity of studies involving SOT patients, current available data suggests that the use of RDTs helps improve patient outcomes and minimizes inappropriate antimicrobial use when coupled with proactive ASPs. Future studies should focus on clinical outcomes in SOT patients specifically, as well as how to optimize the use of RDTs in conjunction with traditional microbiology methods..
