Rate and Predictors of 30-Day Readmission following Diabetic
This study aimed to describe rates and characteristics of non-elective 30-day readmission among adult patients with diabetes mellitus type 1 (T1DM) hospitalized for diabetic ketoacidosis (DKA) and also identify predictors of readmission.

The study analyzed the Nationwide Readmission Database. DKA hospitalizations in patients with T1DM were classified using ICD-10-CM codes. It utilized Chi-square tests to compare baseline characteristics between readmissions and index hospitalizations. Multivariable cox regression was employed to identify independent predictors of readmission. Following this, a 30-day readmission risk scoring system based on independent predictors was developed.

-- The 30-day all-cause readmission rate for DKA was 19.4%.

-- A majority of patients (64.8%) had DKA as the principal diagnosis on readmission.

-- Readmitted patients had a significantly higher mean age (35.3 vs. 34.9 years) and a higher proportion of females (52.8 vs. 49.6%) compared to the index admission.

-- Readmission following DKA was associated with higher odds of inpatient mortality (0.69 vs. 0.24%, OR: 2.84).

-- Independent predictors of 30-day all-cause readmission included female sex, index hospitalizations with Charlson Comorbidity Index (CCI) score of 3 or greater, and being discharged against medical advice (AMA).

Conclusively, the readmission rate for DKA in T1DM patients is high, and most patients have DKA as the principal diagnosis on readmission. A CCI equal to or greater than 3, hypertension, female sex, and being discharged AMA were significant predictors of readmission.
