Abstract

|
|
Background: This study aimed to investigate perceptions of Clostridioides difficile infection (CDI) diagnostic tests among physicians who prescribe CDI diagnostic tests as part of providing direct patient care.
Methods: In August 2018, we provided a 12-question survey of gastroenterologists (the most common referral source for CDI testing) to 35 medical institutions in Korea, asking them about their perceptions of CDI diagnosis and testing.
Results: A comparison of the perceptions of physicians and clinical pathologists (CPs) found that physicians had a lower perceived sensitivity of the toxin AB enzyme immunoassay test. For nucleic acid amplification tests, physicians exhibited a perception of higher assay sensitivity and specificity than CPs. The specificity of culture tests was generally perceived
as high by physicians, whereas CPs regarding expressed mixed opinions. All but one physician and one CPs found the algorithmic test useful. Concerning the CDI isolation criteria, physicians commenced patient isolation by concurrently assessing both test results and clinical symptoms, rather than exclusively relying upon test results. Among CPs, 84.6% said they could rely on symptoms to determine when to release a patient from isolation, while 46.2% of physicians said they would rely on test results.
Conclusion: This study provides useful information on the status of laboratory diagnosis of
CDI in Korea and what needs to be improved, which will help to standardize and improve
laboratory diagnosis of CDI in Korea.
