Insights
Male gender, high magnesium, high platelets, and low HbA1c are key risk factors for major amputation in diabetic foot ulcer patients. Understanding these factors aids in preventing limb loss for individuals with diabetes.
Area of Science:
- Endocrinology
- Vascular Surgery
- Diabetology
Background:
- Diabetic foot ulcers are a significant cause of morbidity and mortality.
- Major amputation is a devastating complication, impacting quality of life and survival.
Purpose of the Study:
- To identify independent risk factors for major amputation in hospitalized patients with diabetic forefoot ulcers.
Main Methods:
- Retrospective analysis of 1032 diabetic patients with forefoot ulcers admitted between 2003-2018.
- Collected data on 88 potential risk factors, including demographics, ulcer characteristics, and serological markers.
- Utilized univariate and stepwise multiple logistic regression to identify significant predictors of amputation.
Main Results:
- Four factors remained significant predictors in multivariate analysis: male gender, elevated magnesium, elevated platelets, and decreased glycated hemoglobin (HbA1c).
- Male gender (OR 8.216) and increased magnesium (OR 2.480) were associated with higher amputation risk.
- Increased platelet count (OR 1.009) showed a slight association, while lower HbA1c (OR 0.570) was protective.
Conclusions:
- Male gender, elevated serum magnesium, and elevated platelet levels are significant risk factors for major amputation in diabetic forefoot ulcer patients.
- Lower levels of glycated hemoglobin (HbA1c) appear to be protective against major amputation.
- These findings can inform targeted interventions to reduce amputation rates in this vulnerable population.
Aims:
The purpose of this study was to investigate the risk factors for major amputation in patients hospitalized with diabetic forefoot ulcers.
Methods:
Between January 2003 and December 2018, a total of 1792 diabetic patients were admitted to the diabetic wound center for the management of diabetic foot ulcers. Among the patients, 1032 diabetic patients with forefoot ulcers were included in this study. Nine hundred and eighty-three patients (95%) healed without major amputations while 49 patients (5%) healed after major amputations. Data related to 88 potential risk factors including demographics, ulcer condition, vascularity, bioburden, neurology, and serology were collected from the patients in these two groups for comparison.
Results:
Among the 88 potential risk factors, 34 showed statistically significant differences between the two groups. In the univariate analysis of 88 risk factors, 33 showed statistically significant differences. In stepwise multiple logistic regression analysis, four of the 33 risk factors remained statistically significant. The multivariate-adjusted odds ratios for gender, magnesium levels, platelet levels, and glycated hemoglobin (HbA1c) levels were 8.216, 2.480, 1.009, and 0.570, respectively.
Conclusion:
Risk factors for major amputation in patients hospitalized with diabetic forefoot ulcers include male gender, increased magnesium, increased platelet levels, and low levels of HbA1c.
