Abstract

INTRODUCTION: Diabetes mellitus (DM) with complication is a major cause of morbidity and mortality and is associated with a high re-admission rate (RR) and economic burden on health care. This study was done to determine demographic parameters associated with high RR secondary to DM.

METHODS: Nationwide Inpatient Sample data was used to extract data of patients discharged with DM for year 2012-2014 using clinical classification software (CCS). NIS represents 20% of all hospital data in US. All the patients who were discharged with primary diagnosis of DM with complications and readmitted within 30 days were identified and categorized based on admitting diagnosis. Patients were classified as readmissions secondary to DM with complication as primary cause, readmissions with DM with complication as secondary cause and non-DM associated readmissions. Chi-square analysis was done for statistical significance.

RESULTS: We identified a total of 1,457,583 admissions for DM nationwide during the study period with total 30-day RR of 45.7%. 30-day RR for DM as primary diagnosis accounted for 9.1%. Age group (18-44), females, patients under Medicaid and living in metropolitan areas had higher 30-day RR secondary to DM as a primary cause and secondary to non-DM related causes (p<0.01).

CONCLUSION: Our study identifies the demographic parameters associated with high 30-day readmission rate for Diabetes mellitus with complications. It reveals that DM with complications is associated with high 30-day RR. Strategies to reduce morbidity and healthcare cost should be targeted more in these groups with high RR.
