Abstract
Objective Diabetic foot ulcers (DFUs) are complications of diabetes that can progress with high mortality and morbidity. It is a preventable problem with the determination of risk factors and patient education. Our aim is to examine the knowledge and behavior of diabetic patients in our region about foot care.
Materials and Methods Diabetic individuals who applied to the Endocrine and Internal Medicine Clinic were included in this cross-sectional study. Demographic variables, physical examination, and laboratory findings were recorded. “Diabetic foot information form for diabetic foot care” was used to evaluate the patient’s level of knowledge about diabetic foot and care. The questionnaire consists of 16 questions with two options, right or wrong, according to the suggestions of the guides. A total of 16 points scoring system has been established, 1 point for each correct answer and 0 points for the wrong answer.
Results “Total acknowledgment scores” (TAS) were significantly higher in patients with DFU, amputation, and DFU history (p < 0.001). TAS were significantly lower in patients receiving oral antidiabetic therapy than those receiving insulin therapy (p = 0.005). Total scores were significantly lower in untrained patients compared with primary school graduates (p = 0.005), and in high school graduates compared with university graduates (p < 0.001).
Conclusion In this study, a serious lack of information or insufficiency was found in patients with diabetes. More comprehensive training programs are needed to reduce diabetic foot development and complications.

Introduction
Diabetes mellitus (DM) is a metabolic disease with acute and chronic complications. Diabetic foot ulcers (DFUs), on the other hand, are one of the complications in which diabetes patients are affected by approximately 25% of their lives.[1] Diabetic foot (DF) is the most common reason for hospitalization in patients with diabetes, and its mortality and morbidity are high.[2] [3] Quality of life and social activities of patients with DF are severely affected because of pain, inactivity, and loss of sensation. The first reason for foot amputations is known as DF, and foot amputation rate in diabetic patients is 24%.[4]
DFU develops due to changes in foot pressure foci due to diabetic neuropathy, blood loss in diabetic vasculopathy, and recurrent trauma. In unhealed DFUs likely to go to amputation, the first goal is to protect the patient from lower limb amputations.[5] According to the American Diabetes Association, early diagnosis and treatment of diabetic patients can prevent ulcers and amputation or other negative consequences of risky feet.[6] For this purpose, it is necessary to recognize the feet at risk, to take effective treatment and measures. Education is the most important part of success in prevention. Some studies have shown that regular foot self-care significantly reduces lower limb amputations.[7]
Turkey Diabetes, Hypertension, Obesity and Endocrinology Diseases Prevalence Study (TURDEP-II) showed an alarming increase in diabetes rates in Turkey. According to the study, the frequency of diabetes has been reported to have increased by 90% over the past 12 years from 7.7 to 13.7%.[8] In parallel with this increase, diabetes complications are likely to increase. Therefore, it is very important to prevent complications such as DF, which brings serious social and economic problems. In this study, it was aimed to evaluate the awareness and behavior of DF care in our region.

Materials and Methods
In this cross-sectional study, outpatients and inpatients admitted to the Endocrine and Internal Medicine Clinics of our hospital between September 2018 and June 2019 were included. Age, gender, height, weight, body mass index (kg/m2), type of diabetes, duration of diabetes, drugs, history of smoking, and history of DF problems were recorded. On physical examination, blood pressure, peripheral pulses, and neurological examination were evaluated. Laboratory findings of glucose, hemoglobin A1c (HbA1c), lipid profile, and other biochemical and hematological parameters were noted.
“The diabetic foot information form for diabetic foot care” was used to assess the patient’s level of acknowledge about DF and care. In our country, there is no valid and reliable measurement tool to measure the level of knowledge. Therefore, a questionnaire was prepared according to the principles of DF care and prevention. The questionnaire consists of 16 questions with two options as right or wrong according to the recommendations of the IDF Clinical Practice Recommendations on the Diabetic Foot 2017,[9] Preventive Foot Care.[10] [7] A total of 16-point scoring system was created, 1 point for each correct answer and 0 points for the wrong answer ([Table 1]). Each patient was given diabetes education after the questionnaire.
The study protocol was in accordance with the Helsinki Declaration of Human Rights and was confirmed by the Yozgat Bozok University Clinical Research Ethics Committee in August 13, 2018 (2017-KAEK-189_2018.09.12_02) and informed consent form was taken from all participants.
#
Statistical Analyses
All statistical analyses were calculated with the Statistical Package for the Social Sciences, version 15.0 (Chicago, Illinois, United States). A p-value of < 0.05 was considered as statistically significant. The characteristics of participants were compared using an analysis of variance and Student’s t-test for normal distributions. t-Test was used in normal distributions and Mann-Whitney U and Kruskal–Wallis were used in the abnormal distribution. Stepwise linear regression analysis was performed to determine the interfering factors from among the patients’ demographics with the assumption of the total knowledge score and the total score after education as the dependent variables, respectively.
#
Results
Three hundred and fifty-four diabetic patients were included in the study. The mean age of the participants was 59.44 ± 11.85 years. Note that 61.3% (217) were females and 38.7% (137) males. Note that 2.3% of them had type 1 diabetes. The mean diabetes duration of patients was 9.64± 7.27 years. Eighty-three percent of participants had smoking habit. The demographic features are shown in [Table 2] and diabetic complications rate in [Table 3].

Of the 354 patients, 84 (23%) had no formal education, 212 (59.8%) had primary education, 34 (9,6%) graduated high school and 24 (6.7%) graduated from university.
Note that 10.2% (36) of patients had a history of foot ulcers. A total of 2.5% (9) of the patients had previous foot, toe, or leg amputation. Note that 8.2% of patients had sores, ulcers, or blisters on the foot. Thirteen percent (46) of patients had callus on their feet. Twenty-six percent (92) of the patients had diabetic neuropathy.
#
Knowledge of Foot Care
The mean total acknowledge score (TAS) was 6.84 ± 3.53. Note that 9.3% (33) of them check their feet every day. Note that 4.8% (17) of diabetic patients check the soles of their shoes for any foreign matter or lining in every clothing. [Table 4] shows the factors affecting the TAS. TAS were significantly higher in patients with DFU, amputation, and DFU history (p < 0.001). The TAS was significantly lower in patients receiving oral antidiabetic therapy than insulin treatment (p = 0.005).
The TAS were 4.83 ± 2.81 in patients with no formal education, 7.22 ± 3.49 in patients with primary education, 7.36 ± 2.66 in patients that graduated high school, and 9.71 ± 3.79 in patients that graduated university. Total scores were significantly lower in patients with no formal education compared with primary school graduates (p = 0.005), and in high school graduates compared with university graduates (p < 0.001) ([Fig. 1]).

In correlation analysis, TAS was negatively correlated with age (r =–0.18 p = 0.01), and positively correlated with duration of diabetes (r = 0.136, p = 0.01), glucose (r = 0.117, p = 0.015), and HbA1c (r = 0.13, p = 0.015).
We analyzed linear regression to investigate the interference of each of the variables on the TAS of the diabetics. Age (confidence interval [CI]: 0.07–0.062, p = 0.015), diabetes foot education (CI: 3.53–5.37, p < 0.001), patient education level (CI: 0.73–1.52, p < 0.001), and history of DFU (CI: 2.03–4.02, p < 0.001) were found to be independent predictors of the total score.
#
Discussion
Our study demonstrated that the majority of patients with diabetes do not have sufficient knowledge and skills in foot care. Inexperience in nail care, foot hygiene, and controls, interpretation of DFU symptoms (redness), effects of smoking on DFU formation, and selection of suitable shoes were determined.
Education is directly related to DF care. Knowledge and self-care were found seriously insufficient in individuals with low education level. The scores of diabetic individuals with low education level were found to be quite low. The relationship between education and information can also be explained by the fact that the educated patient can use educational materials and information technologies to obtain information. Reports from India, Iran, and Pakistan also support these results.[11] [12] [13]
Studies to prevent DF wounds emphasizes the importance of blood sugar regulation, proper footwear, foot and nail care, regular foot examinations, and patient education.[14] [15] The purpose of DM training programs with including the patient in the management of the disease is to improve metabolic control, to prevent acute and chronic complications, and to improve the quality of life. Only 42 (13.4%) patients received diabetes and DF training.
People with diabetes are likely to have 15 to 40 times more knee-leg amputations than the general population. The presence of DFU is 36 times more likely to lead to future ulcer development.[9] In our study, TAS was found to be significantly higher in patients with a history of DFUs and amputation.
Diabetic peripheral neuropathy (DPN) is one of the main factors of DFU. In a multicenter study conducted, coexistence of minor trauma, deformity, and DPN has been shown to account for 63% of DFU.[16] Due to diabetic neuropathy, the pressure foci of the feet change, and the feeling of pain decreases, and the feet become vulnerable. Shoes that do not match should not be worn, the method used to warm the cold feet and trainings on nonbarefoot gain more importance for patients with diabetic neuropathy. In our study, no significant difference was found in TAS compared with those without neuropathy. In addition, there was no significant difference in TAS in patients with callus due to varying foci of pressure on the foot. This situation was interpreted as a reflection of the lack of education observed throughout the study.
The results of the studies conducted with the DF knowledge level differ according to the regions. While the level of knowledge was low in one study in Sudan, the level of knowledge was found good in another study in Saudi Arabia.[17] [18] This difference may be related to the participants living in urban and rural areas, accessing health centers, and the number of health care professionals in the region. In a study conducted in China, low self-care skills were associated with education, duration of diabetes, lack of regular periodic examinations, and diabetes complication training.[19] It can be said that regular doctor control increases awareness of foot care.[20]
There are some limitations of this study. First, the knowledge level form does not include all of the knowledge and practices related to DF care. Second, the questionnaire we used was not confirmed by the test–retest method. To minimize the margin of error, locally and internationally accepted rules were used to prepare the survey.[21] [22] [23] Finally, although a sufficient number of patients participated in the study, as it is a single-center study it does not represent Turkey’s profile.
#
Conclusion
As a result, diabetes and DF education of the patients were poor and this was closely related to the patient’s educational status and DF education. Although diabetes and DF education progress with special effort of the clinics, it does not seem sufficient. Patients need more information about diabetes and DF by health care professionals.
