Half of all Americans over 60 years of age have diverticulitis of the colon. Over the last decade, the use of elective colon resection has increased by more than 50%, and diverticulitis is now the leading reason for elective colectomy. Surgeons and patients alike have a difficult time deciding if surgery is the best choice to treat diverticulitis. The goal of the DEBUT study is to improve the understanding about how doctors and patients make decisions to have elective surgery for diverticulitis, and the global impact of diverticulitis on patients' lives.


This study will examine both clinical and non-clinical reasons for pursuing surgery, taking into account previously unexplored areas in surgical decision-making including the comprehensive impact of this disease, as well as factors that impact a surgeon's willingness to recommend surgery. Ultimately, this patient-centered research approach will help us understand the impact of treatment decisions on a patient's quality of life, work, and clinical symptoms, and will ultimately help to inform our recommendations for the treatment of patients with diverticulitis.

The DEBUT study was developed from questions raised by our Washington State Surgical Collaborative, (SCOAP Colon and Rectal Surgery Work Group) and will be carried out in clinics and hospitals across Washington State, Oregon, and California. The investigators invite patients to participate in research activities designed to identify the impact of diverticulitis and treatment options, in order to better understand the outcomes that matter most to patients. Patients who are considering surgery or who have received treatment for their diverticulitis will be recruited for study participation. Participants will complete a baseline survey via a convenient electronic platform, and follow-up surveys will be sent quarterly for up to four years. These surveys will examine quality of life, overall health, and clinical symptoms to understand what drives patients and surgeons to an operation, as well as how that decision impacts quality of life and recurrent events in patients that choose to have surgery compared to those that do not have surgery. Participating surgeons will complete surveys that examine their indications for surgery and surgical outcomes.
