Official title

Treatment Individualized Appendicitis Decision-Making (TRIAD) Patient Surveys

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

While appendectomy has been the main treatment of appendicitis for over 100 years, recent European studies found that, at least among highly selected patients, antibiotics alone can be an effective alternative. Surgeons and patients alike have a difficult time deciding if surgery or antibiotics are the best choice to treat appendicitis. The goal of the TRIAD is to evaluate the patients who are a part of the TRIAD implementation program and assess satisfaction and decisional regret for patients with appendicitis. This information will be used to inform the design of decision-support interventions to help patients improve their ability to make an informed decision in-line with their preferences and values.
