Protocol-Based Intravenous Fluid Hydration for Newly Created Ileostomies Decreases Readmissions Secondary to Dehydration

High risk populations for unplanned healthcare utilization following ostomy construction

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.
