Clostridium Difficile-Associated Infection in Trauma Patients: Development of the Clostridium Difficile Influencing Factors (CDIF) Score
Karamanos E, Gupta AH, Stanton CN, Mohamed A, Patton JH, and Schmoekel N. Clostridium difficile-associated infection in trauma patients: Development of the clostridium difficile influencing factors (CDIF) score. Perm J 2018;22:18-013.
CONTEXT: Clostridium difficile-associated infection (CDAI) can result in longer hospitalization, increased morbidity, and higher mortality rates for surgical patients. The impact on trauma patients is unknown, however.
OBJECTIVE: To assess the effect of CDAI on trauma patients and develop a scoring system to predict CDAI in that population.
METHODS: Records of all trauma patients admitted to a Level I Trauma Center from 2001 to 2014 were retrospectively reviewed. Presence of CDAI was defined as evidence of positive toxin or polymerase chain reaction. Patients with CDAI were matched to patients without CDAI using propensity score matching on a ratio of 1:3.
MAIN OUTCOME MEASURES: Primary outcome was inhospital mortality. Secondary outcomes included length of stay and need for mechanical ventilation. A decision-tree analysis was performed to develop a predicting model for CDAI in the study population.
RESULTS: During the study period, 11,016 patients were identified. Of these, 50 patients with CDAI were matched to 150 patients without CDAI. There were no differences in admission characteristics and demographics. Patients in whom CDAI developed had significantly higher mortality (12% vs 4%, p < 0.01), need for mechanical ventilation (57% vs 23%, p < 0.01), and mean hospital length of stay (15.3 [standard deviation 1.4]) days vs 2.1 [0.6] days, p < 0.0).
CONCLUSION: In trauma patients, CDAI results in significant morbidity and mortality. The C difficile influencing factor score is a useful tool in identifying patients at increased risk of CDAI.
