The Burden of Diabetic Foot Ulcers in Urban India: A Community Healthcare Setup-Based Study

Foot ulcer is the most common cause of hospitalisation among people with diabetes (PWD). The objective of the study is to determine the incidence of diabetic foot ulcers (DFUs) in the urban community in India and its relationship with glycemic level and demographic parameters like age and sex among diabetic patients.

A retrospective observational study was performed from January 2016 to December 2018 at an urban community set up in Mumbai. The study was conducted in a healthcare setting, providing lifelong contributory healthcare to beneficiaries of an employees' universal healthcare scheme. PWD from the community was identified using prescriptions of anti-diabetic medications. We identified patients with DFUs from electronic medical records from the hospital information system (HIS). The yearly incidence rate of DFU among PWD was estimated for the study period. The association between glycemic control and the demographic profile of patients with DFU was studied using binary logistic regression.

The study documents the average incidence of 66 DFU patients among 10,000 PWD per year in the community. Logistic regression analysis showed higher odds for the elderly age group (OR 2.863) compared to lower age for developing DFU. Similarly, poor control (HbA1c >7%) over glycemic level has a higher chance (OR 1.713) of DFU than that of optimum glycemic control (HbA1c ≤7%). Among the DFU, 15.29% of patients required amputation during the study period.

The study documents the community-level incidence of DFUs among patients with diabetes. High glycemic levels and elderly age groups (≥60) are the associated risk factors for DFU.
