Diabetes mellitus is a major public health problem with rising prevalence globally, and it is estimated that it will increase to 642 million by 2040.[1] Diabetes mellitus is one of the leading cause of death according to World Health Organization,[2] and it attributed to 5 million deaths globally in 2015. International Diabetes Federation has recently estimated that 69.2 million people are affected by diabetes in India.[1]

About 10% of patients of type 2 diabetes mellitus at the time of diagnosis have one or more risk factors for foot disease, like peripheral vascular disease and peripheral neuropathy.[3] As numbers of cases are increasing rapidly the diabetes related foot disease and complication are expected to increase. Andrew et al.[3]; have estimated that about 3%-10% of people worldwide with diabetes have a foot ulcer, with the lifetime risk for developing foot ulcers 15%. Barshes et al.[4]; in their study, noted that a large majority of diabetics patients do not know or receive any guideline-recommended for self-foot care. A similar study by Basu et al.[5]; in UK noted that 33% of diabetics did not receive information about foot self-care. Wikblad et al.[6]; noted that about 87% of people with diabetes never reported and never inspected their feet, and 66% diabetics were not interested in diabetes self-foot care.

Diabetic foot is one of the most devastating and disabling complication in diabetics and is defined as a group of syndromes in which ischemia, neuropathy, and superadded infection lead to tissue breakdown and possible amputation.[7] About 15% of diabetic patients will develop foot ulcers in their lifetime and, if not appropriately treated, leads to chronic ulcer, chronic osteomyelitis, and finally amputation in 85% of the cases.[8] According to The International Working Group on the Diabetic Foot, in every 20 seconds, somewhere in the world diabetics loses their leg due to its complication and after such amputations, over half of these people will die within 5 years.[9] Jain et al.[8]; in their study, estimated that approximately 45,000 legs or foot amputation are being done every year in India which can be avoided by diabetic foot self-care practice.

Most foot or leg amputations can be prevented or at least delayed just by foot self-care at home.[10] Long term diabetes lead to microangiopathy, neuropathy which decreases the foot sensation and even with minor trauma foot ulcer develops without any pain and go unnoticed by patients.[11] It further gets worsened by poor foot hygiene, inappropriate footwear, and delay in seeking medical attention. Self-care of foot can be taught, and these external modifiable risk factors can be minimized to prevent ulcers.[12] More recently, diabetic foot care has been talked about and gaining international consensus. In the present literature there are inconsistent results and no concrete evidence that self-foot care alone can prevent foot ulcer and subsequent amputation and it is because of lack of randomized trials. However, this lack of evidence is not evidence of any effect.[1314] American Diabetes Association has formulated current guidelines for standardized care of foot in diabetic patients that recommend yearly screening for high risk feet. Foot care education is to be given to those who are at high risk.[15]

In India, the number of diabetics is constantly increasing, and its related complications are also expected. This results in increased morbidity, mortality, and economic burden on patients, as medical insurance in India is very low.

Prevention of diabetic foot ulceration is very important and crucial to minimize foot related morbidity and mortality and the danger of amputation. A large number of associated modifiable external factors work together to cause diabetic foot ulceration, and these factors can be modified. These include incorrect footwear, toes nails deformity, external trauma, and mechanical stress. Internal factors like peripheral vascular disease and peripheral neuropathy also play a major role in developing diabetic foot ulceration.[161718]

Periodically and regular self-foot examination by the patient or by a physician is required to minimize diabetic foot ulceration, infection; however, it involves a multi-disciplinary team approach that can reduce the chance of development of ulcers by 50% and amputations by 85%.[1419]

The present study was conducted to determine the prevalence of awareness of self-foot care in diabetics who attended the orthopedics and diabetics OPD in our hospital.

Material and Methods

Approval of institutional ethics committee was taken prior to conducting the study. All included patients were confirmed cases of Type II diabetes mellitus. The study was conducted between Mar 2018 and Dec 2019.

Including criteria:

  • Age more than 19 years
  • Confirmed case of Type I & type II diabetes mellitus
  • Diabetes mellitus with or without peripheral neuropathy
  • Diabetes mellitus with or without peripheral vascular disease.

Excluding criteria:

  • Patients with gestational diabetes mellitus
  • Cerebral stroke
  • Leg or foot amputation
  • Non diabetic Peripheral vascular disease or neuropathy
  • Hansen’s disease
  • Foot deformities like CTEV, Pes planus, Cavus foot, etc., were excluded
  • Previous h/o healed diabetic ulcer or present ulcer.

All included patients were given a self-explanatory questionnaire to enquire about awareness regarding self-foot care, responses obtained were assessed through self-explanatory questionnaire, as suggested by K. Kaliyaperuma in his book.[20] In our study, foot self-care practices were observed from the Summary of Diabetes Self-Care Activities (SDSCA) measure.[21] Diabetes Self-Management Questionnaire (DSMQ) was also used to assess awareness designed by[22] and evaluated by Schmitt et al.[23]; All included patient’s feet were examined by authors for presence of peripheral vascular disease, neuropathy, foot ulcer, toe nail deformity, or any other pathology that put foot at risk.

Peripheral neuropathy was assessed using the Modified Neuropathy Disability Score (NDS). The severity of Peripheral neuropathy was graded after adding of assessment scores and classified as (a) absence of neuropathy (score 0), (b) mild neuropathy (score 1–3), (c) moderate neuropathy (score 4–7) and (d) severe neuropathy (score >7). Peripheral vascular disease was defined as ABPI of <0.9; arterial atherosclerosis was defined as ABPI of >1.3.[23]

Ankle-brachial pressure index was measured by a hand-operated Doppler machine with ankle brachial pressure index of 0.9 was kept as a cutoff point. International Diabetes Federation Guideline Development Group (IDF) guideline was used to assess risk factors, and was classified as (a) foot at “no added risk”, (b) foot “at risk” (foot has one risk factor without previous history of foot ulceration or amputation) and (c) foot at “high risk” (foot has more than one risk factor with or without history of ulcer or amputation).[24]

Statistical analysis

In this study, data was analyzed using SPSS statistical package version 19 (IBM, Chicago USA). To determine odds ratios Univariate and multivariate logistic regressions were used. Comparison between two groups was done using Pearson correlation (Chi-square) and Fisher’s exact test for categorical variables. For continuous variables, a student’s t-test was used to assess the difference between groups. A P value was set at less than 0.05 to consider as significant.


A total of 1687 patients were included in this study, of which 1074 (63.7%) were females and 613 (36.6%) were males. Demographic characteristics of the study population are shown in Table 1. In the present study, the Point prevalence of diabetic foot ulcers was 15.3% (95% CI: 2.17–5.92). Education level has a significant difference between patients with diabetic foot ulcers than those without ulcers. (p = 0.041).

Table 1:
Demographic characteristics of diabetic patients with and without the presence of diabetic foot ulcers

However, socioeconomic status did not significantly differ between patients with diabetic foot ulcers than those without ulcers. (p = 0.0763).

The magnitude of risk factors to develop diabetic foot ulcers in univariate and multivariate analysis has been shown in Table 2. In univariate logistic regression analysis, age >45 years, patients on insulin therapy, and those who had neuropathy has increased chances to develop a diabetic foot ulcer. Those who were graduate have shown lesser chances to develop diabetic foot ulcer because of awareness. Smoking and alcoholism were not much associated with the development of foot ulcer. However, in multivariate analysis, insulin therapy, combination therapy, and neuropathy were significant predictors of foot ulcers. Patients with moderate and severe neuropathy have eight and twenty six-time respectively more chances to develop a diabetic foot ulcer.

Awareness about dietetic self-foot care

Awareness and knowledge about self-foot care and its risk factors among the study population are shown in Table 3. The maximum total score for all knowledge questions was 23, which means the higher the score better the knowledge. Patients’ responses vary from 0–23, with a mean score of 9.41 ± 8.92 S.D (95% CI: 10.67–12.59). The mean score was similar among patients with diabetic foot ulcer and those without ulcer. Higher level of financial status, education, people doing or retired from a government job and longer duration of type II diabetes have awareness and some knowledge about self-foot care and have higher mean scores.

Table 3:
Mean scores of awareness and knowledge on diabetes self-foot care among diabetic patients

In the present study, 905 patients (53.6%) had received information about self-foot care. However, the duration of diabetes had no effect on foot ulcer irrespective of information about self-foot care (p = 0.782). The majority of patients received awareness and knowledge from their treating physician (51.6%) and family physician (31.1%).

Self-Foot care practices observed by patients at the time of study has been summarizes in Table 4. Foot self-inspection was done daily only by 51.6% of patients.

Self Foot care practices observed by patients at the time of the study

Patients who had their foot examination once by a physician care for their foot more than those who had not been examined by a physician. However, only 686 patients (40.6%) have their feet inspected by a physician at any event once since their initial diagnosis [Table 5].

It is estimated that diabetics have 15% higher lifetime risk of developing diabetic foot ulcer however, and many studies noted lifetime incidence as high as 25 % to 32.9%.[1242526] However, it was noted as low as 4.1% by Saad et al.[27] In the present study, the awareness regarding diabetic foot ulcer was 22.5%.

Reiber et al.[28] have described that peripheral neuropathy is the most common clinical symptom in the development of diabetic foot ulceration. The prevalence of diabetic peripheral neuropathy in India ranges from 10.5% to 32.2%,[293031] and it is up to 50% in a developed country.[32] In the present study, the prevalence of peripheral neuropathy was 28.7%, while the prevalence among patients with foot ulcers was 91.7%. Many published data have shown that patients with moderate diabetic peripheral neuropathy were eight times more likely to develop foot ulcers. Those with severe neuropathy were 24 times more likely to develop foot ulcers than those with no neuropathy.[303132]

Development of peripheral neuropathy and foot ulcer later on was mainly due to ignorance of patients about self-foot care and such observation signify the importance of education on self-care foot which was insensate. In order to prevent minor trauma, infection, and ulcer, self-foot care is mandatory. Education and awareness regarding strict glycemic control and foot care should be implemented at every diabetic clinic. In the elderly and patients with long-standing diabetes, foot care should be emphasized on each OPD visit and their feet should be examined by a treating physician once.

On the contrary to peripheral neuropathy, peripheral vascular disease was present in 164 (9.76%) of patients and was associated with diabetic foot ulcers too. However, Boyko et al.[33] from Seattle, and Al-Mahroos et al.[34] from Bahrain, reported that peripheral vascular disease is an independent risk factor for developing a foot ulcer.

Awareness about self-foot care

Awareness about self-foot care in diabetics in preventing foot ulcers is a widely accepted fact, and published data support this. In the present study, more than 50% of diabetic patients who have no foot ulcer reported that they had never received any information regarding foot care. However, those has foot ulcer reported that they have some awareness regarding self-foot care but they could not do it due to busy schedule. The health care giver is partly responsible not to emphasize on self-foot care because of heavy rush in outpatient department. However, even those who received information it was partial or not fully understood by patients.

To educate each patient individually in a thick rush of outpatient department is nearly impossible in many tertiary care hospitals in India. To call each patient on the next day in outpatient department is not feasible and it incurs an additional cost. Education on self-foot care can be given at the primary health care center level or by a family physician to avoid the unnecessary rush in tertiary care hospital.

As many patients were not much educated, and their awareness score was influenced by level of their education. It was seen that patients with a longer duration of diabetes have some awareness compared to patients with a shorter duration of diabetes because they received knowledge from either family physician or hospital.

Many published studies have noted that low awareness and knowledge scores were attributed to low level of education.[3536373839] More recently Fatima et al.,[40] noted only 7% of the study population (among 358 patients) had good foot care knowledge and practices, 55.3% had average and 37.7% had poor foot care knowledge and practices. Foot ulceration in educated diabetic patients was less because they are likely to read and obtain information regarding foot care from different sources.

Methods for safe diabetic Foot self-care

Present study shows many patients were not aware of foot self-care practice and a large number were not taught by primary or family physician. A large number of patients did not inspect their feet regularly or even once a week. They don’t know that they were using the wrong footwear that can cause foot abrasion and ulceration in their insensate foot. Few patients showed their risky behaviors, like cutting toenails with blades or scissors and not using proper nail cutter, and it comprises as high as about 75% of the study population. They usually ignore the minor cut or abrasion, use homemade medication, and do not take proper physician consultation that leads to infection and ulceration. Foot self-care are practices are somewhat similar in all patients, but those who were aware are doing in a scientific and methodical way. Those patients whose feet have been inspected once by physicians are able to take care for their foot as they taught.

Role of primary care physician

There is a need of education in community regarding self-foot care among diabetics and that can be done at all primary health care hospital in all district level. Patients can be made aware for self-foot care by video, photographs and by organizing small audio-visual sessions. This may reduce the unnecessary work load on tertiary care hospital and improve overall patient care.


The prevalence of diabetic foot ulcers is high among patients attending diabetic opd in our hospital. Many risk factors like Peripheral neuropathy and microangiopathy is the major risk factor for foot ulcer. Peripheral neuropathy leads to sensation loss, and the patient may be unaware of any minor injury. Awareness and knowledge about self-foot care are low among patients with diabetes. Education and proper training by health care providers can improve awareness and understanding.

By this study, we conclude that there is a requirement to educate and raise awareness among diabetic patients by health care givers regarding the importance of self-foot care practices and identifying risk factors for foot ulcers. Every diabetic clinic in tertiary care hospitals should incorporate a self-foot care program in outpatient department services. There is a need for continuous education on foot care to improve patients’ awareness and knowledge of risks and foot self-care practices.

Key points and take-home message: It is now most important to introduce self-foot care education programs among diabetics at domiciliary, primary as well as tertiary care level. Primary health care giver needs to do regular and periodic reinforcement regarding self-foot care to reduce the incidence of diabetic foot ulceration, gangrene and eventually amputations.
