Background:
Patients with a new ostomy have high rates of unplanned healthcare utilization (UPHU). We used machine learning to assess which factors contributed the most to UPHU after ostomy construction.
Methods:
We retrospectively studied new ostomy patients between 2018 and 2021 at a single institution. The primary outcome was UPHU within 60 days of discharge. Factors that contributed the most to UPHU were assessed using a classification tree machine learning method.
Results:
Among 318 patients, 30.8 % of patients had an UPHU event. The classification tree identified diabetes mellitus as the most important factor associated with UPHU: 56 % of diabetics had UPHU. Smoking history was the next most important factor: 77 % of diabetics who smoked had UPHU. Patients who had diabetes, smoked, and had chronic kidney disease had the highest UPHU rate at 86 %.
Discussion:
Unplanned healthcare utilization after ostomy construction is highest among patients with diabetes, smoking history, and chronic kidney disease.

Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
