Patient education for preventing diabetic foot ulceration

Impact of Diabetes Foot Care Education on Amputation Rate in the University of Abuja Teaching Hospital, Nigeria

Ulceration of the foot is a major problem for people with diabetes. In a developing country like Nigeria, huge challenge is caused by diabetes foot problems. The aim of this study was to determine the impact of diabetic foot care education of patients and health care staff on the outcome of diabetic foot complications in our hospital. This was a pre and post design carried out from April 2013 to March 2014 on 155 diabetes patients. Patient education was carried out by diabetes nurses and doctors, at diagnosis and re-enforced at follow-up clinics. At the end of 1 year, the impact of education was assessed. Descriptive statistics were generated as appropriate. A total of 155 patients, 64 (41%) males and 91 (59%) females, were studied with mean age of 49 ± 3 years and mean duration of diabetes 6 ± 2.6 years. At the onset of the program, 70% of the patients had no knowledge of foot care education. Only 13.5% knew that diabetes mellitus foot ulcer could be related to long duration of diabetes, nerve damage, blood vessel blockage, foot deformity, and uncontrolled blood glucose. Ninety-two percent of the patients preferred home remedies, herbal treatment, or chemist in the event of an ulcer. After the program, 77% would seek hospital care as first option, and amputation rate decreased from 50% in 2009 to 10% by 2017. Our experience has shown that education is the cheaper option for the prevention of lower limb amputation in a resource-poor setting like ours.

Diabetic foot workshop: Improving technical and educational skills for nurses

Diabetes mellitus as one of the most common metabolic disorders has some complications, one of the main ones is diabetic foot (DF). Appropriate care and education prevents 85% of diabetic foot amputations. An ideal management to prevent and treat diabetic foot necessitates a close collaboration between the health team members and the diabetic patient. Therefore, improving nurses' knowledge about DF care and advancement in the quality of care provided by the nurses could significantly improve diabetic foot prevention and management. Therefore, the aim of DF workshop was to improve technical and educational skills of the nurses to prevent and manage diabetic foot. Considering the vital role of the nurses in providing DF care, EMRI decided to conduct Diabetic foot workshop for them. The following five steps were designed for the 14 coordinating sessions in the workshop: Goals definition, deciding about attendees, location selection, creating agenda, and developing a follow-up plan. "Diabetic Foot Workshop for Nurses" provides appropriate training to DF nurses at the national level; and combining theory and practice in this workshop not only increases nurses' knowledge, but also improves their skills in the field of the diabetic foot. Providing education and care to patients by DF nurse specialists instead of general nurses could be an important output of this workshop, which may lead to DF prevention and amputation decrease in the long term.

Literature review on the management of diabetic foot ulcer

Diabetic foot ulcer (DFU) is the most costly and devastating complication of diabetes mellitus, which affect 15% of diabetic patients during their lifetime. Based on National Institute for Health and Clinical Excellence strategies, early effective management of DFU can reduce the severity of complications such as preventable amputations and possible mortality, and also can improve overall quality of life. The management of DFU should be optimized by using a multidisciplinary team, due to a holistic approach to wound management is required. Based on studies, blood sugar control, wound debridement, advanced dressings and offloading modalities should always be a part of DFU management. Furthermore, surgery to heal chronic ulcer and prevent recurrence should be considered as an essential component of management in some cases. Also, hyperbaric oxygen therapy, electrical stimulation, negative pressure wound therapy, bio-engineered skin and growth factors could be used as adjunct therapies for rapid healing of DFU. So, it’s suggested that with appropriate patient education encourages them to regular foot care in order to prevent DFU and its complications.

Patient education for preventing diabetic foot ulceration

BACKGROUND

Ulceration of the feet, which can result in loss of limbs and even death, is one of the major health problems for people with diabetes mellitus.

OBJECTIVES

To assess the effects of patient education on the prevention of foot ulcers in patients with diabetes mellitus.

SEARCH METHODS

We searched The Cochrane Wounds Group Specialised Register (searched 03 September 2014); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 8).

SELECTION CRITERIA

Prospective randomised controlled trials (RCTs) that evaluated educational programmes for preventing foot ulcers in people with diabetes mellitus.

DATA COLLECTION AND ANALYSIS

Two review authors independently undertook data extraction and assessment of risk of bias. Primary end points were foot ulceration or ulcer recurrence and amputation.

MAIN RESULTS

Of the 12 RCTs included, the effect of patient education on primary end points was reported in only five. Pooling of outcome data was precluded by marked, mainly clinical, heterogeneity. One of the RCTs showed reduced incidence of foot ulceration (risk ratio (RR) 0.31, 95% confidence interval (CI) 0.14 to 0.66) and amputation (RR 0.33, 95% CI 0.15 to 0.76) during one-year follow-up of diabetes patients at high risk of foot ulceration after a one-hour group education session. However, one similar study, with lower risk of bias, did not confirm this finding (RR amputation 0.98, 95% CI 0.41 to 2.34; RR ulceration 1.00, 95% CI 0.70 to 1.44). Three other studies, also did not demonstrate any effect of education on the primary end points, but were most likely underpowered. Patients' foot care knowledge was improved in the short term in five of eight RCTs in which this outcome was assessed, as was patients' self-reported self-care behaviour in the short term in seven of nine RCTs. Callus, nail problems and fungal infections improved in only one of five RCTs. Only one of the included RCTs was at low risk of bias.

AUTHORS' CONCLUSIONS

In some trials, foot care knowledge and self reported patient behaviour seem to be positively influenced by education in the short term. Yet, based on the only two sufficiently powered studies reporting the effect of patient education on primary end points, we conclude that there is insufficient robust evidence that limited patient education alone is effective in achieving clinically relevant reductions in ulcer and amputation incidence.

Assessing decreased sensation and increased sensory phenomena in diabetic polyneuropathies

Loss of sensation and increased sensory phenomena are major expressions of varieties of diabetic polyneuropathies needing improved assessments for clinical and research purposes. We provide a neurobiological explanation for the apparent paradox between decreased sensation and increased sensory phenomena. Strongly endorsed is the use of the 10-g monofilaments for screening of feet to detect sensation loss, with the goal of improving diabetic management and prevention of foot ulcers and neurogenic arthropathy. We describe improved methods to assess for the kind, severity, and distribution of both large- and small-fiber sensory loss and which approaches and techniques may be useful for conducting therapeutic trials. The abnormality of attributes of nerve conduction may be used to validate the dysfunction of large sensory fibers. The abnormality of epidermal nerve fibers/1 mm may be used as a surrogate measure of small-fiber sensory loss but appear not to correlate closely with severity of pain. Increased sensory phenomena are recognized by the characteristic words patients use to describe them and by the severity and persistence of these symptoms. Tests of tactile and thermal hyperalgesia are additional markers of neural hyperactivity that are useful for diagnosis and disease management.

The care process of diabetic foot ulcer patients: a qualitative study in Iran

Background

The Purpose of this study is to clarify the care process for Iranian diabetic patients with diabetic foot ulcer condition.

Methods

The main question of this research was “How is the care process for diabetic foot ulcer patients and how do patients experience it?” This study was within the Grounded Theory method. Data collection was carried out until data saturation was achieved. Saturation was achieved after interviewing 11 patients, 4 physicians, one head nurse and one nurse.

Results

Three main themes emerged from this study, including: “disease management, disease experience and continuity of care”. Each of these themes is consisted of different sub-themes.

Conclusions

This is the first study to describe the care process in Iranian diabetic patients with diabetic foot ulcer disease. Knowing patients’ experience and the manner of dealing with them once faced with foot ulcer condition could facilitate a comprehensive decision making by therapists and better recovery of diabetic patients.

Improving health outcomes with better patient understanding and education

A central plank of health care reform is an expanded role for educated consumers interacting with responsive health care teams. However, for individuals to realize the benefits of health education also requires a high level of engagement. Population studies have documented a gap between expectations and the actual performance of behaviours related to participation in health care and prevention. Interventions to improve self-care have shown improvements in self-efficacy, patient satisfaction, coping skills, and perceptions of social support. Significant clinical benefits have been seen from trials of self-management or lifestyle interventions across conditions such as diabetes, coronary heart disease, heart failure and rheumatoid arthritis. However, the focus of many studies has been on short-term outcomes rather that long term effects. There is also some evidence that participation in patient education programs is not spread evenly across socio economic groups. This review considers three other issues that may be important in increasing the public health impact of patient education. The first is health literacy, which is the capacity to seek, understand and act on health information. Although health literacy involves an individual's competencies, the health system has a primary responsibility in setting the parameters of the health interaction and the style, content and mode of information. Secondly, much patient education work has focused on factors such as attitudes and beliefs. That small changes in physical environments can have large effects on behavior and can be utilized in self-management and chronic disease research. Choice architecture involves reconfiguring the context or physical environment in a way that makes it more likely that people will choose certain behaviours. Thirdly, better means of evaluating the impact of programs on public health is needed. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework has been promoted as one such potential approach.

Patients' perspectives on foot complications in type 2 diabetes: a qualitative study

BACKGROUND

Foot ulceration is a major health problem for people with diabetes. To minimise the risk of ulceration, patients are advised to perform preventive foot self-care.

AIM

To explore beliefs about diabetic foot complications and everyday foot self-care practices among people with type 2 diabetes.

DESIGN OF STUDY

Qualitative study using one-to-one interviews.

SETTING

A suburban primary care health centre.

METHOD

Semi-structured interviews with a purposive sample of adults with type 2 diabetes but with no experience of foot ulceration.

RESULTS

Most participants were unsure of what a foot ulcer is and unaware of the difficulties associated with ulcer healing. Prevention of accidental damage to the skin was not considered a priority, as few participants knew that this is a common cause of foot ulceration. Although it was recognised that lower-limb amputation is more common in people with diabetes, this was perceived to be predominantly caused by poor blood supply to the feet and unrelated to foot ulceration. Therefore, preventive foot care focused on stimulating blood circulation, for example by walking barefoot. Consequently, some of the behaviours participants considered beneficial for foot health could potentially increase the risk of ulceration. In some cases the uptake of advice regarding preventive foot care was hampered because participants found it difficult to communicate with health professionals.

CONCLUSION

Patients with type 2 diabetes may have beliefs about foot complications that differ from medical evidence. Such illness beliefs may play a role in foot-related behaviours that have previously been unrecognised. Health professionals need to explore and address the beliefs underlying patients' foot self-care practices.

Double blind, randomized, placebo controlled clinical trial for the treatment of diabetic foot ulcers, using a nitric oxide releasing patch: PATHON

Background

Diabetes Mellitus constitutes one of the most important public health problems due to its high prevalence and enormous social and economic consequences. Diabetic foot ulcers are one of the chronic complications of diabetes mellitus and constitute the most important cause of non-traumatic amputation of inferior limbs. It is estimated that 15% of the diabetic population will develop an ulcer sometime in their lives. Although novel therapies have been proposed, there is no effective treatment for this pathology. Naturally produced nitric oxide participates in the wound healing process by stimulating the synthesis of collagen, triggering the release of chemotactic cytokines, increasing blood vessels permeability, promoting angiogenic activity, stimulating the release of epidermical growth factors, and by interfering with the bacterial mitochondrial respiratory chain. Topically administered nitric oxide has demonstrated to be effective and safe for the treatment of chronic ulcers secondary to cutaneous leishmaniasis. However, due to their unstable nitric oxide release, the topical donors needed to be applied frequently, diminishing the adherence to the treatment. This difficulty has led to the development of a multilayer polymeric transdermal patch produced by electrospinning technique that guarantees a constant nitric oxide release. The main objective of this study is to evaluate the effectiveness and safety of this novel nitric oxide releasing wound dressing for the treatment of diabetic foot ulcers.

Methods and design

A double-blind, placebo-controlled clinical trial, including 100 diabetic patients was designed. At the time of enrollment, a complete medical evaluation and laboratory tests will be performed, and those patients who meet the inclusion criteria randomly assigned to one of two groups. Over the course of 90 days group 1 will receive active patches and group 2 placebo patches. The patients will be seen by the research group at least every two weeks until the healing of the ulcer or the end of the treatment. During each visit the healing process of the ulcer, the patient's health status and the presence of adverse events will be assessed. Should the effectiveness of the patches be demonstrated an alternative treatment would then be available to patients.
