Evaluation of risk factors for lower extremity amputation in diabetic foot ulcer: a hospital based observational study in Northern India

摘要

Background: The present prospective observational study was done to analyse the risk factors leading to minor or major lower extremity amputation (LEA) in diabetic patients. Methods: A 139 patients were divided into Group A (n=113) and Group B (n=26) who underwent minor and major LEA respectively. Results: Majority of the patients in group B were from rural and lower socioeconomic background. Duration of diabetes (p=0.017) and of DFU was significantly longer in group B (P 0.001) The pro-portion of patients with Wagner Grade 4 and 5 ulcer were significantly higher in group B than in group A (P 0.001) Wound infection and maggots were significantly higher in group B though polymicrobial infection was higher in group A. Biochemical investigations were abnormally altered but difference between two groups was not significant. Conclusions: Socioeconomic burden on the society due to LEA can be reduced by making diabetic patients aware of foot hygiene, regular medical check-up for control of diabetes and associated complications.
