Study summary

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.

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. Patient-reported symptom burden and quality of life measured by the Diverticulitis Quality of Life scale (DV-QOL)

    Patient-reported burden of disease (diverticulitis symptoms and quality of life, as measured by the Diverticulitis Quality of Life scale (DV-QOL)) will be measured over time among patients that do and do not undergo elective colon resection.

    Time frame: 3 months - 4 years

Secondary outcomes

  1. Number of patients who report non-clinical factors as reason for deciding to have surgery

    Patient-reported factors (clinical and non-clinical) for deciding to have elective colon surgery, or deciding to have medical management for diverticulitis will be analyzed across surgical and non-surgical patients.

    Time frame: 3 months - 4 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 5, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
