Assessment of the relationship between self-efficacy criteria and rate of lower limb amputation in diabetic patients; a cross-sectional study.

Abstract

According to the high prevalence of diabetes Mellitus (DM), as a harmful metabolic disease, the adoption of self-care (SC) behaviors along with modern medications seems necessary for diabetes Mellitus patients (DMPs). Since self-efficacy (SE) affects the quality of SC behaviors in DMPs to prevent limb amputation as one of the most common DM-related complications, the present study aimed to investigate the probable relationship between the effect of the Diabetes Management Self-Efficacy (DMSE) with limb amputation rate in DMPs. DMPs with ages of 18-65 years were selected and divided into two groups of the case (DMPs with experiences of DM ≥ 4 years and limb amputation, n = 300), and control (DMPs with no experience of limb amputation, n = 600). Data were collected through demographics, clinical checklists, and the DMSES tool, and were analyzed using SPSS (v.25). The mean age of DMPs was 55.2 ± 8.2 years, and 59.3% and 40.7% of patients had type I and type II DM, respectively. A significant relationship was found between the mean of DMSES in terms of groups of the case (Mean: 60.6) and control (mean 67.7) (P = 0.001), living place, education, family background in non-close relatives, underlying disease, high blood pressure, hyperlipidemia, and the type of DM. The odds ratio (OR) of amputation was also found higher in DMPs with a lower mean of DMSES OR = 1.03, CI 95%=1.01-1.04, P = 0.001). In this study, DMSE had a significant relationship with reducing limb amputation rate in DMPs. Furthermore, The average self-efficacy score according to gender, place of residence, education, family history in non-close relatives, underlying disease, and type of diabetes was significantly difference. It is suggested, that self-efficacy would be enhanced through systematic education in diabetes clinics. The online version contains supplementary material available at 10.1007/s40200-023-01331-0.
