Assessment of Contributing Factors and Wound Severity in Diabetic Foot Ulcer - A Prospective Study
Abstract
The study aims to assess the factors contributing to the development of Diabetic Foot Ulcer (DFU) and wound severity of ulcer in DFU, and also to assess the type of dressing used and provide relevant patient care education to patient with DFU. It is a prospective observational study conducted for 6 months, from November 2021 to April 2022 in the in-patient and out-patient facility of the surgery Department at ESIC Hospital, Nacharam, Hyderabad, Telangana in India. A total of 103 subjects were included in the study. The contributing factors of DFU and wound severity were assessed by Wagner-Meggitt classification system. This study concluded that along with hyperglycemia, hypertension (55.33%), traumas (33%) are the leading risk factors for DFU. The highest number of patients falls under moderate numbness. Various types of dressing used in different severity grade patients was assessed and was found that highest type of dressing used was saline dressing. Based on wound severity specific counselling points were provided to the patient to progress the wound healing process. Counselling regarding diabetic diet and lifestyle modification was provided based on the GRBS (Glycemic index) of the patients.

Introduction
In India, around 3 crores patients were diagnosed with Diabetes by 2021. Prevalence rate among Adults in urban region were found to be 9% and in rural region it is 3% 1. Diabetes is a metabolic condition that occurs due to inability of pancreas to produce sufficient amounts of insulin or due to improper usage of insulin by the body 2. Diabetic foot occurs due to ulceration with neuropathy and/or peripheral arterial disease. It is a serious and damaging complication of diabetes and can be caused due to lack of feeling in the foot, poor circulation, foot deformities, irritation (such as friction or pressure), trauma, duration of diabetes.
In order to provide treatment plan and follow up, proper diagnosis and classification of DFUs are required. Wagner-Meggitt classification system is based mainly on the depth of the wound and it consists of 6 wound grades. The Wagner diabetic foot ulcer classification system assesses the depth of the ulcer and the presence of gangrene and osteomyelitis by the following grades—Grade 0 – intact Skin, Grade 1 – superficial ulcer of skin or subcutaneous tissue, Grade 2 – ulcers extend into tendon, bone, or capsule, Grade 3 – deep ulcer with osteomyelitis, or abscess, Grade 4 – partial foot gangrene, Grade 5 – whole foot gangrene and requires amputation 3. There are different methods for dressing the wound they are alginate dressing, hydro fiber dressing, foam dressing, hydrocolloid dressing, low-adherence dressing, hydrogel dressing, transparent film dressing, and papaya dressing.
Regular foot examinations to check the presence of foot abnormalities are important to prevent Diabetic foot ulcer, it can be self-examination or clinical examination. Diabetes related complications are reduced by controlling blood glucose levels. Regular maintenance of healthy diet, lifestyle and taking prescribed medications as directed can play vital role in managing diabetes. The risk of damaging the nerves that can further lead to DFU can be prevented by controlling blood glucose levels. Quit smoking, ensure no injuries to feet and increase risk of injury and burns, wash your feet regularly with lukewarm water and soap, maintain good foot hygiene, always check for foot related complications during medical visits, selecting healthy food choices, optimal exercise, maintain normal bodyweight.

Among 103 subjects under study, patients with glucose level below 200mg/dl were found to be high represented in Figure 11. Among 103 patients there are 12 high risk patients which are divided based on wound grade severity. The results found to be 66.6% of complications and co-morbidities, 16.6% of trauma & co-morbidities, 8.3% of only DM and 8.3% of only trauma represented in Figure 12. Among the subjects under study highest num of patients with high risk of severity falls under grade 1 (47.6%) which are trauma and co-morbidities group, and follows with only trauma (45.4%) in grade 2. Most of the patients fall under grade-3 wound severity, in that the patients are more in only co-morbidities (21.5%) represented in Figure 13.
DISCUSSION
In our study of subject size 103 patients, pain (88.34%), swelling (75.72%) and redness (74.75%) were the majorly observed symptoms, which is similar to a study conducted by Saneh Khunkaew et al. of sample size 12 which states that presence of pain and high levels of C –Reactive Protein is observed which indicates inflammation 4. In our study with subject size of 103, 55.33% of the patients have hypertension as co-morbidity which is most observed comorbidity, similarly a study conducted by Khalid Al-Rubeaan et al. at sample size of 62681 of which 46.90% patients have hypertension as comorbidity which is one of the major contributing factor in DFU 5.
In our study of subject size 103, 56.3% of the patients are previously diagnosed DFU patients and 43.6% are newly diagnosed patients. In our study with subject size of 103 subjects, most number of patients fall under grade-1(30%), grade-2(20.3%), grade-3(20.3%), which states that patients mostly fall in moderate severity, which is similar to a study conducted by Andrew J. Boulton et al. in general population of US states that patients who fall under grade-1,2,3 will heal in a moderate time period 6. In our study, with subject size of 103 subjects, most of the patients fall under stage-2 class of 25.24%. In our study with subject size of 103 subjects, patients with amputation falls under the grade-5(10.6%), which is similar to a study conducted by Yotsapon Thewjitcharoen et al. of a sample size of 290 patients, states that 26.9% have amputation 7.
In our study, with subject size of 103 subjects, most of the patients are under moderate numbness group of 64.07%. In our study with subject size of 103 subjects, papaya dressing (22.33%) and saline dressing (60.19%) are used which can be correlated to a comparative study conducted by Vasuki V et al. of subject size 100 in which 50 % are treated with papaya dressing and 50% are treated with saline dressing which states that Papaya dressing is a better enzymatic dressing agent which can be suggested when compared to wet to dry normal saline mechanical debridement. In our study with subject size of 103 subjects, patients with GRBS level below 200mg/dl were found to be slightly higher (50.48%) when compared to GRBS level above 200mg/dl (48.54%).
CONCLUSION
This study with sample size of 103 DFU patients, were assessed the contributing factors and wound severity by using Wagner-Meggitt classification system. After assessment of 103 patients, this study had concluded that, the contributing factors are HTN (Hypertension), trauma and uncontrolled hyperglycemia are the leading factors or risk factors for DFU. This study assessed and reported the types of dressing used in different severity grade patients; and used the Wagner-Meggitt classification system to find out the wound severity in order to give specific counselling points to the patient to progress the wound healing process and also, this study had taken the data from patients about GRBS (Glycemic index) to counsel their diabetic diet and even counseled about lifestyle modification.
