Abstract

In 2021, the American College of Gastroenterology and Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America released guidelines for Clostridioides difficile infection (CDI) management, with conflicting recommendations. We surveyed US gastroenterologists (GIs), infectious disease (ID) specialists, and primary care physicians (PCPs) on their use of clinical guidelines and attitudes toward gut microbial therapies for CDI.
We conducted an online survey of 302 physicians (n = 101 GIs, 101 IDs, 100 PCPs; February 24 to March 13, 2023). Included GIs and IDs saw a minimum of 3 to 4 patients and PCPs 1 to 2 patients with CDI per month.
Physicians working in hospital/academic settings were more familiar with CDI guidelines than those working in independent/group practices. Half of GIs used American College of Gastroenterology guidelines; 98% of IDs followed Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America guidelines. More PCPs reported that their institutions did not have set guidelines (40%). More GIs (51%) and IDs (74%) used the recommended multistep algorithm for CDI testing; PCPs were more likely to use a single diagnostic test (49%). GIs and IDs more often prescribed vancomycin taper (93% and 98%, respectively) and fidaxomicin (87% and 97%, respectively); PCPs were more likely to prescribe metronidazole (84%). Less than 10% of physicians felt very knowledgeable about donor-derived microbiome therapies. While 60% of GIs, 53% of IDs, and 50% of PCPs agreed donor-derived microbiome therapies are essential for CDI management, more than 50% cited the need for real-world evidence of safety and efficacy.
Education around CDI guidelines and standardized diagnostic and treatment algorithms are needed to ensure consistent CDI management.
