Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Antibiotics Therapy Arm | Patients in the antibiotics (abx) arm will receive a total of 10 days of abx, with a minimum of 24 hours using an IV abx formulation (administered in q8, q12, or q24 hour regimens with or without concurrent oral abx) followed by oral abx for the remainder of the 10 days. Patients will be offered a treatment regimen of abx based on guidelines published jointly by the Surgical Infection Society and the Infectious Disease Society of America. Any of the IV abx options (Single antibiotic-Cefoxitin, Ertapenem, Moxifloxicin, Tigecycline, Ticarcillin-Clavulanic Acid or Dual antibiotics-Metronidazole plus one of the following-Cefazolin, Cefuroxime, Ceftriaxone, Cefotaxime, Ciprofloxacin, Levofloxacin) will be considered acceptable. After IV abx, a regimen of oral abx will be continued for a total treatment length of 10 days.~C | 37 | 676 | OG000 |
| Group 2 | Appendectomy Arm | Patients in the appendectomy arm will have an appendectomy performed by an open or laparoscopic approach, depending on patient and surgeon preference. Prior to their operation, patients in this arm will receive one dose of antibiotics per currently accepted standards when appendicitis diagnosis is confirmed. Patients may also receive preoperative antibiotics per hospital standards for surgical infection prevention bundle.~Appendectomy: Appendectomy will be performed by an open or laparoscopic approach, depending on patient and surgeon preference. | 21 | 656 | OG001 |
