Inappropriate Testing for Clostridioides difficile in Long-Term Care: Implications Highlight the Need for an Algorithm

Abstract

This article provides clear guidance related to appropriate testing for Clostridioides difficile (C. diff) and identifies the negative implications of inappropriate testing, repeat testing, and testing for cure. Residents of long-term care (LTC) facilities are at increased risk for developing C. diff. Complications can arise if a resident does not have an active C. diff infection (colonization) and has a positive C. diff laboratory test result. The authors share a fictional bedside story illustrating the negative consequences that can result from inappropriate C. diff testing, and present a decision tree that promotes mindful application of testing, which may result in cost savings and prevent adverse resident outcomes.
