Healthcare Resource Utilization in Controlled Versus Uncontrolled Adults Living With Type 1 Diabetes in the South African Public Healthcare Sector [Editor's Choice]

Abstract

Objectives

This study aimed to understand the cost implications of managing people living with type 1 diabetes mellitus in the South African public healthcare system.

Methods

A multicenter, noninterventional retrospective chart review study was performed. Data on healthcare resource consumption, demographics, risk factors, clinical history, and acute events were collected. Direct medical costs were collected over a 1-year period, stratified by controlled versus uncontrolled patients. In addition, the costs in people with controlled (glycated hemoglobin 7%) versus uncontrolled glycated hemoglobin (≥ 7%) at time horizons of 1, 5, 10, and 25 years were modeled using the IQVIA Core Diabetes Model.

Results

The costs based on the retrospective chart review were $630 versus $1012 (controlled versus uncontrolled population). The modeled costs at various time horizons were as follows: at 1 year, $900 versus $1331; at 5 years, $4163 versus $6423; at 10 years, $7759 versus $16 481; and at 25 years, $16 969 versus $66 268. The largest cost in the controlled population was severe hypoglycemia requiring nonmedical assistance, severe hypoglycemia requiring medical assistance, and treatment costs. In the uncontrolled population, the largest cost was the cost of diabetic ketoacidosis, severe hypoglycemia requiring nonmedical assistance, severe hypoglycemia requiring medical assistance, and foot complications.

Conclusions

Strict glycemic control reduces healthcare resource use overall. Patients in the controlled group still experienced high resource use related to hypoglycemic events. The introduction of a structured patient education program and analog insulins may result in less episodes of hypoglycemia and potential cost savings.
