Awareness regarding foot self-care practices among diabetic patients in Northeast part of India. Can primary care physician make a difference? A hospital based cross-sectional study

Abstract

Background: About 10% of patients with type 2 diabetes mellitus at the time of diagnosis have more than one risk factor for developing foot ulceration, and it increases to 15% in a lifetime. The risk of development of Diabetic foot ulcers/gangrene can be prevented by the patient's self-foot care practice at home. The present study aimed to determine the prevalence of awareness of self-foot care practice among diabetic patients in a rural setting. The study also aimed to identify the factors preventing dry or wet diabetic gangrene development and subsequent amputation.

Methods: A hospital-based cross-sectional study was carried out among 1687 people with diabetes mellitus (DM) who attended orthopedic and diabetic OPD in a tertiary care hospital in Kamrup, Assam, India. An appropriate self-explanatory questionnaire about knowledge of self-foot care practice was given to all study participants. Foot examination was performed by authors participated in the study on all patients. The observations and results were categorized according to the International Diabetes Federation foot risk categories.

Results: Of 1687 patients included in this study, 298 (17.7%) had foot ulcers of various grades, 164 (9.76%) had peripheral vascular disease, and 484 (28.7%), had peripheral neuropathy of different grades. After multivariate analysis, patients on insulin and combination therapy and peripheral neuropathy were significantly associated with the presence of foot ulcers. The mean knowledge score was as low as 9.7 ± 4.8 out of a total score of 23. Low awareness and knowledge were associated with low mean scores due to a lack of formal education (8.3 ± 6.1). Among the 1687 patients, only 381 (22.5%) are aware and have some knowledge about self-foot care, and 686 (40.6%) had their feet examined by a doctor only once since their initial diagnosis. The incidence of development of diabetic-related complications was significantly low in those who know about foot self-care as well as those whose feet had been inspected by a physician at least once.

Conclusion: The incidence of development of diabetic-related complications was significantly low in those who know about foot self-care as well as those whose feet had been examined by a physician of family doctors at least once. There is a need to educate all patients of diabetes about self-foot care. It is prudent to establish an integrated foot care services within primary care centers and in the diabetic clinic to identify feet at risk, institute early preventive measures, and provide continuous foot care education through images videos on WhatsApp to patients and primary health care givers.
