OBJECTIVES: To evaluate the safety of antimotility agents (AAs) in a population of patients with hematologic malignancies and concurrent Clostridioides difficile infection (CDI) and to describe the outcomes of AA use in a hospital setting.

PATIENTS AND METHODS: We used the electronic health record to identify patients who were hospitalized in the adult malignant hematology service who had 1 or more toxin-positive C difficile stool assay between April 1, 2012, and September 21, 2017. We reviewed medical charts to obtain information on the use of AAs and any subsequent gastrointestinal complications.

RESULTS: There were 339 patients who were stool toxin positive for CDI during the study period. Of those, 94 patients (27%) were prescribed AAs within 14 days of CDI diagnosis. All patients received CDI antimicrobial therapy within the first 24 hours. There were 2 adverse gastrointestinal events in the group that received AAs and 6 in the group that did not receive AAs. The risk of adverse events did not differ between patients who received AAs and those who did not (adjusted odds ratio, 0.36; 95% CI, 0.06 to 2.10). The mean age of the full cohort was 52.7±15.5 years, and the mean length of stay was 26.7±22.6 days. Early AA use (<48 hours of diagnosis) was not associated with increased adverse effects.

CONCLUSION: There was no increase in the incidence of gastrointestinal events in the arm that used AAs compared with the control arm. The evidence suggests that for patients with hematologic malignancies and CDI, the addition of AAs to appropriate antimicrobial therapy poses no additional risk.
