INTRODUCTION
In 2017, the Journal of Clinical Microbiology published a Point-Counterpoint on the laboratory diagnosis of Clostridium difficile infection (CDI). At that time, Ferric C. Fang, Christopher R. Polage, and Mark H. Wilcox discussed the strategies for diagnosing Clostridium difficile colitis in symptomatic patients (J Clin Microbiol 55:670–680, 2017, https://doi.org/10.1128/JCM.02463-16). Since that paper, new guidelines from the Infectious Diseases Society of America and the Society for Health Care Epidemiology have been published (L. C. McDonald, D. N. Gerding, S. Johnson, J. S. Bakken, K. C. Carroll, et al., Clin Infect Dis 66:987–994, 2018, https://doi.org/10.1093/cid/ciy149) and health care systems have begun to explore screening asymptomatic patients for C. difficile colonization. The theory behind screening selected patient populations for C. difficile colonization is that these patients represent a substantial reservoir of the bacteria and can transfer the bacteria to other patients. Hospital administrators are taking note of institutional CDI rates because they are publicly reported. They have become an important metric impacting hospital safety ratings and value-based purchasing, and hospitals may have millions of dollars of reimbursement at risk. In this Point-Counterpoint, Cliff McDonald of the U.S. Centers for Disease Control and Prevention discusses the value of asymptomatic C. difficile screening, while Dan Diekema of the University of Iowa discusses why caution should be used.
