The primary outcome is 30 day all-cause mortality. This binary outcome is the most suitable and reported outcome for FCDC. The secondary outcomes are: 1) 30 day morbidity, a composite binary outcome to include all Clavien-Dindo grade 2-5 (serious) complications (6) which also includes death (Clavien grade 5); 2) 90 day all-cause mortality (binary) in order to capture those who survive the first month but have a long and complicated hospitalization with poor outcome; 3) restoration of gastrointestinal continuity by ileostomy closure (binary) which serves as a surrogate for excellent recovery; 4) length of hospital stay, a censored outcome, using time to discharge as the outcome censoring by death (patients who die during hospitalization will contribute towards length of stay for the days that they survived).
