Patient with Diabetic Foot Ulcer Admitted in Surgery Ward; Risk Factors, Associations and Grades of Presentation

Abstract

Background: The management of chronic diabetic foot ulcers (DFU) poses a great challenge to the treating physician and surgeon. The aim of this study was to identify the risk factors, clinical presentation, and outcomes associated with chronic DFU. Objective: To determine the various risk factors for diabetic foot ulcers and study their associations. To study the grades of diabetic foot ulcers at presentation. Method: Purposive sampling. This study was done in the Surgery department of Shaheed Ziaur Rahman Medical College Hospital (SZMCH), Bogura for period of twelve (12) months. 100 cases were selected after informed consent. Study group (A) comprises of 50 cases of type 2 diabetes with diabetic foot ulcer and control group (B) comprises of 50 cases of age and gender matched type 2 diabetics without foot ulcers. Patients having serious systemic illness, type I diabetics and non-diabetic patients presenting with foot ulcer were excluded. Age, gender, duration of diabetes, duration of ulcer, glycemic control, presence of neuropathy and vascular disease were documented. Grading and Staging of ulcer was done according to New University of Texas Diabetic Wound Classification. Various risk factors were compared between the two groups. Data analyzed via SPSS version 17 with significant p-value < 0.05. Results: Among 100 cases (64 % males & 36 % females); mean age was 58.50 ± 9.8 (group A) versus 50.40 ± 10.5 (group B). Mean duration of diabetes was longer in group A (10.49 ± 7.06 years) vs. group B (8.34 ± 4.83 years) (p = 0.019). Glycemic control was poor in group A (72 %) vs. group B (56 %) (p = 0.045). There was significantly more peripheral vascular disease in group A (50 %) vs. group B (32 %) (p= 0.005). Sensory neuropathy was more in group A (90 %) vs. group B (38 %) (p < 0.0001). Grade-I ulcer was present in 16 % cases, Grade-II in 38 % and Grade-III in 46 %. Conclusion: Neuropathy carries highest risk for diabetic foot ulcer, followed by peripheral vascular disease and poor glycemic control. Therefore, diabetic patient must be educated about these risk factors, foot care and self-examination and to have regular screening by clinician. Appropriate glycemic control and timely medical and surgical intervention may reduce morbidity in diabetics.
