Predictors of 90-day Colonic Diverticular Recurrent Bleeding and Readmission

Area of Science:

• Gastroenterology
• Clinical Medicine
• Internal Medicine

Background:

• Colonic diverticular bleeding is a common cause of gastrointestinal hemorrhage.
• Recurrence of bleeding and subsequent hospital readmissions are significant clinical challenges.

Purpose of the Study:

• To identify predictors of recurrent colonic diverticular bleeding.
• To determine factors associated with 90-day hospital readmission after an initial bleeding episode.

Main Methods:

• Retrospective comparative study of 144 patients with colonic diverticular bleeding.
• Analysis of clinical characteristics during hospitalization, comparing patients with and without recurrent bleeding/readmission.
• Multivariate analysis to identify independent predictors.

Main Results:

• Hypovolemic shock on admission, blood transfusion, and hyperlipidemia were associated with higher rates of recurrent bleeding and readmission.
• Shock on admission (OR 5.118) was a significant independent predictor of recurrent bleeding and readmission.

Conclusions:

• Hypovolemic shock upon admission is a key predictor for recurrent colonic diverticular bleeding and 90-day readmission.
• Endoscopic hemostasis should be carefully considered and adequately performed for patients presenting with shock.
