Classification systems for lower extremity amputation prediction in subjects with active diabetic foot ulcer: a systematic review and meta-analysis

Introduction: Diabetes mellitus is a metabolic syndrome that is marked by higher blood glucose. The uncontrolled high blood glucose can lead to complication, such as diabetic foot. Diabetic foot is the most reason why diabetic patients are hospitalized. Diabetic foot that cannot heal may lead to lower extremity amputation. The purpose of this study was to describe the risk factors of lower extremity amputation in diabetic foot ulcer patients.Methods: This study used a case-control study of diabetic foot patients in Dr. Soetomo General Hospital from January 2015 to December 2017. This study used the data from medical records in Inpatient Installation Department of Internal Medicine. Patients with diabetic foot ulcer and lower extremity amputation due to diabetes were included in this study. Incomplete medical records were excluded. Data of samples were divided to two groups, i.e. the amputation group and the non-amputation group with a ratio of 1:1. Risk factors of amputation that were analyzed were male, old age, and the history of ulcer/lower extremity amputation.Results: Based on the data of 36 samples, there were 11 male patients (61.1%) and 7 female patients (38.9%) who experienced lower extremity amputation. The average age of amputation group was 59.61 years old with a range of ages from 39 to 72 years old. This study found the risk factors for lower extremity amputation in diabetic foot ulcer patients was the history of ulcer/amputation due to diabetes (OR 5.0, 95% CI 1.065-23.464, p = 0.034). Conclusion: The risk factor for lower extremity amputation in diabetic foot ulcer patients was the history of ulcer/amputation due to diabetes.

Background: The study is to determine the relation between the high HbA1c and ESR as prognostic factors with the severity of the diabetic foot ulcer disease, particularly, in predicting the final outcome in the form of higher incidence of lower extremity amputation (LEA) and/or prolonged hospital stay. The study explored the importance of increased level of serum HbA1c and erythrocyte sedimentation rate (ESR) in determining the final outcome of the disease. It revealed that the severity of diabetic foot ulcer disease is more in patients who had concomitant high levels of baseline HbA1c and ESR on admission.Methods: This observational study was done in 89 patients who were admitted in the surgical wards of the two teaching hospitals in India. The cohort consisted of patients from the age of 26 to 83 years of age who presented with clinically infected foot ulcers. Routine blood tests were done which include HbA1C on the day of admission and fasting ESR (1st hour) on the next day morning. The standard X-ray plates were routinely taken on the first day for determination of the involvement of underlying bones and soft tissues. The outcome of the diabetic foot ulcer was assessed from the severity of the disease according to Meggit-Wagner classification, the incidence of lower extremity amputation and the duration of hospital stay.Results: The high levels of baseline HbA1C (more than 7.0%) in blood on the first day of admission was found in all of the 89 patients who were included in this study but the criteria for consideration of high risk was more than 9% which was found in 41 patients. The criteria for consideration of high ESR in this study was set to be 50 mm/h. High ESR of more than 50 mm was found in 63 patients. We had subdivided 31 patients into a High Risk Group whose baseline levels of HbA1C > 9% and ESR > 50 mm/h. The incidence of amputation was 79.31% and 44.44% with HbA1c of more than 9.0% and ESR of more than 50 mm respectively and was considerably increased (83.87%) when both HbA1c and ESR were more than the critical value as set in the study. Similarly, the incidence of prolonged hospital stay of more than 14 days was 58.54% in patients with HbA1C level of greater than 9 %, 51.85% in patients with baseline ESR > 50 mm/h and 93.55% in presence of high levels of both HbA1C (>9%) and ESR (>50 mm/h)..Conclusions: The study observed that the patients who presented with baseline high levels of HbA1C, ESR or both on admission had unfavourable prognosis with increased incidence of lower extremity amputation and prolonged hospital stay than the other patients in the cohort.
