ABSTRACT
INTRODUCTION: Clostridioides difficile infection (CDI) is an important community- and hospital-acquired infection. Patients receiving tube feeding often have diarrhoea, and it is still unclear whether the traditional criteria for submitting samples for Clostridioides difficile (CD) testing as determined by the frequency of the diarrhoea apply to these patients.
METHODS: We conducted a retrospective study comparing the clinical features of tube-fed inpatients with suspected CDI, with CDI, and those without CDI admitted between 2004 and 2020. Univariate associations were assessed using the chi-square test, Fisher's exact test, or student's t-test, and multivariate analysis was conducted using logistic regression analysis.
RESULTS: Among 805 tube-fed inpatients with and suspected CDI, 163 (20.2%) had CDI and 642 (79.8%) did not. The following seven predictors, independently associated with CDI, were used to develop the SEASON GAP score: male (Sex) (1 point), Emaciation (1 point), days from Admission to testing ≥21 days (2 points), Stool frequency/day ≥5 times (1 point), seasON (summer: 2 points, spring and winter: 1 point), GAstrostomy (2 points), and no prior Proton pump inhibitor use (1 point). In a receiver operating characteristic curve, the area under the curve was 0.77 (95% confidence interval: 0.73-0.80). The optimal cut-off point was 3.5. A score of ≤3 had a sensitivity, specificity, and negative predictive value of 81%, 60%, and 93%, respectively.
CONCLUSIONS: The SEASON GAP score is useful in ruling out CDI in patients with tube feeding, thus reducing unnecessary CD testing and antimicrobial use.
