Differences in characteristics between first-ever foot ulcer and recurrent foot ulcer in patients with diabetes: Prospective observational study.

Abstract

More effective preventive care can potentially be provided if the characteristics of both the first ever and the recurrent foot ulcers can be clarified. The purpose of this study was to characterize first ever and recurrent foot ulcers in diabetic patients. This study was conducted as a secondary analysis of a prospective study that was entitled: "Factors associated with the discontinuation of wound care specialist clinic visits in patients with diabetic foot ulcers." In 73 diabetes-related foot ulcer patients who visited one wound clinic in Indonesia between August 2020 and February 2021, we investigated characteristics of the patients and wounds, healing period, and cost. Trauma was shown to be the primary cause of the diabetic foot ulcer in both the first ever foot ulcer (n = 48) and recurrent foot ulcer (n = 25) patient groups (95.8% and 100.0%, respectively). The DMIST score for the first ever foot ulcer patients was significantly higher than the DMIST score for the recurrent foot ulcers. This was found to be especially the case in the first ever foot ulcer patients, as not only were there signs of inflammation (45.8%), but there were also signs of local infection (35.4%), or osteomyelitis and signs of local infection (14.6%) present. In the eightfirst ever foot ulcer patients and in the ninerecurrent ulcer patients who were able to be followed through complete healing, the costs found for the first ever foot ulcer patients were significantly higher as compared to the costs for the recurrent foot ulcer patients. To avoid diabetes-related foot ulcers, specialized educational programs on trauma prevention need to be established. Moreover, patients without diabetes-related foot ulcer histories should be educated regarding the need to undergo early consultations before developing any infections.
