Evidence-based interventions for identifying candidate quality indicators to assess quality of care in diabetic foot clinics: a scoping review. BMC Public Health 2024; 24:996. [PMID: 38600498 PMCID: PMC11005120 DOI: 10.1186/s12889-024-18306-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 03/07/2024] [Indexed: 04/12/2024] Open
Abstract
BACKGROUND Foot ulcers in people with diabetes are a serious complication requiring a complex management and have a high societal impact. Quality monitoring systems to optimize diabetic foot care exist, but a formal and more evidence-based approach to develop quality indicators (QIs) is lacking. We aimed to identify a set of candidate indicators for diabetic foot care by adopting an evidence-based methodology. METHODS A systematic search was conducted across four academic databases: PubMed, Embase CINAHL and Cochrane Library. Studies that reported evidence-based interventions related to organization or delivery of diabetic foot care were searched. Data from the eligible studies were summarized and used to formulate process and structure indicators. The evidence for each candidate QI was described in a methodical and transparent manner. The review process was reported according to the "Preferred Reported Items for Systematic reviews and Meta-Analysis" (PRISMA) statements and its extension for scoping reviews. RESULTS In total, 981 full-text articles were screened, and 322 clinical studies were used to formulate 42 candidate QIs. CONCLUSIONS An evidence-based approach could be used to select candidate indicators for diabetic foot ulcer care, relating to the following domains: wound healing interventions, peripheral artery disease, offloading, secondary prevention, and interventions related to organization of care. In a further step, the feasibility of the identified set of indicators will be assessed by a multidisciplinary panel of diabetic foot care stakeholders.

Abstract
The safety and utility of endotracheal intubation by paramedics in the United Kingdom is a matter of debate. Considering the controversy surrounding the safety of paramedic-performed endotracheal intubation, any interventions that enhance patient safety should be evaluated for implementation based on solid evidence of their effectiveness. A systematic review performed by Hansel and colleagues (2022) sought to assess compare video laryngoscopes against direct laryngoscopes in clinical practice. This commentary aims to critically appraise the methods used within the review by Hansel et al (2022) and expand upon the findings in the context of clinical practice.

Abstract
Introduction To prevent foot ulcers and subsequent amputation on the non-amputated side, we conducted tests for diabetic neuropathy. The results were then used in prosthetic rehabilitation for lower limb amputees with diabetes mellitus. Materials and methods This cross-sectional retrospective study included patients admitted to our convalescent rehabilitation ward for prosthetic rehabilitation between April 2019 and December 2022 following lower limb amputation due to diabetes. We investigated the positive rate of the modified Ipswich Touch Test (mIpTT) in lower limb amputees with diabetes, and physical and orthotic therapy and prosthetic rehabilitation based on medical records. Results Twenty-seven transtibial amputees and nine transfemoral amputees had diabetes. The mIpTT results were positive in 22 (81%) transtibial and eight (89%) transfemoral amputees. There were no apparent differences in positivity rates by amputation level, gender, or age. Based on these results, personalized physical therapy and insoles were prescribed for the non-amputee foot in parallel with prosthetic rehabilitation. Conclusions Lower limb amputees with diabetes have diabetic neuropathy more frequently than diabetic patients without amputation. As a result, they may also be at a higher risk of developing foot ulcers and subsequent amputation due to neuropathy. Therefore, rehabilitation to prevent amputation on the non-amputated side of lower limb amputees with diabetes had better encompassing foot exercises and orthotic therapy on the non-amputated side during the prosthetic rehabilitation period.

Abstract
Diabetes mellitus (DM) induced wound healing impairment remains a serious health problem and burden on the clinical obligation for high amputation rates. Based on the features of wound microenvironment, biomaterials loading specific drugs can benefit diabetic wound treatment. Drug delivery systems (DDSs) can carry diverse functional substances to the wound site. Nano-drug delivery systems (NDDSs), benefiting from their features related to nano size, overcome limitations of conventional DDSs application and are considered as a developing process in the wound treatment field. Recently, a number of finely designed nanocarriers efficiently loading various substances (bioactive and non-bioactive factors) have emerged to circumvent constraints faced by traditional DDSs. This review describes various recent advances of nano-drug delivery systems involved in mitigating diabetes mellitus-based non-healing wounds.

Abstract
Diabetic foot ulcerations have devastating complications, including amputations, poor quality of life, and life-threatening infections. Diabetic wounds can be protracted, take significant time to heal, and can recur after healing. They are costly consuming health care resources. These consequences have serious public health and clinical implications. Debridement is often used as a standard of care. Debridement consists of both nonmechanical (autolytic, enzymatic) and mechanical methods (sharp/surgical, wet to dry debridement, aqueous high-pressure lavage, ultrasound, and biosurgery/maggot debridement therapy). It is used to remove nonviable tissue, to facilitate wound healing, and help prevent these serious outcomes. What are the various forms and rationale behind debridement? This article comprehensively reviews cutting-edge methods and the science behind debridement and diabetic foot ulcers.

Abstract
Background Reliable evidence on the effectiveness of interventions to prevent diabetes-related foot ulceration is essential to inform clinical practice. Well-conducted systematic reviews that synthesise evidence from all relevant trials offer the most robust evidence for decision-making. We conducted an overview to assess the comprehensiveness and utility of the available secondary evidence as a reliable source of robust estimates of effect with the aim of informing a cost-effective care pathway using an economic model. Here we report the details of the overview. [PROSPERO Database (CRD42016052324)]. Methods Medline (Ovid), Embase (Ovid), Epistomonikos, Cochrane Database of Systematic Reviews (CDSR), Database of Abstracts of Reviews of Effectiveness (DARE), and the Health Technology Assessment Journals Library were searched to 17th May 2021, without restrictions, for systematic reviews of randomised controlled trials (RCTs) of preventive interventions in people with diabetes. The primary outcomes of interest were new primary or recurrent foot ulcers. Two reviewers independently extracted data and assessed the risk of bias in the included reviews. Findings The overview identified 30 systematic reviews of patient education, footwear and off-loading, complex and other interventions. Many are poorly reported and have fundamental methodological shortcomings associated with increased risk of bias. Most concerns relate to vague inclusion criteria (60%), weak search or selection strategies (70%) and quality appraisal methods (53%) and inexpert conduct and interpretation of quantitative and narrative evidence syntheses (57%). The 30 reviews have collectively assessed 26 largely poor-quality RCTs with substantial overlap. Interpretation The majority of these systematic reviews of the effectiveness of interventions to prevent diabetic foot ulceration are at high risk of bias and fail to provide reliable evidence for decision-making. Adherence to the core principles of conducting and reporting systematic reviews is needed to improve the reliability of the evidence generated to inform clinical practice.

Effects of Special Therapeutic Footwear on the Prevention of Diabetic Foot Ulcers: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. J Diabetes Res 2022; 2022:9742665.

Abstract
OBJECTIVE To reduce diabetic foot ulcer (DFU) occurrence or recurrence, diabetic therapeutic footwear is widely recommended in clinical practice for at-risk patients. However, the effectiveness of therapeutic footwear is controversial. Thus, we performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to examine whether special therapeutic footwear could reduce the incidence of DFU. METHOD We systematically searched multiple electronic databases (Medline, EMBASE, and EMB databases) to identify eligible studies published from inception to June 11, 2021. The database search, quality assessment, and data extraction were independently performed by two reviewers. Efficacy (i.e., incidence of DFU) was explored using the R'meta' package (version 4.15-1). To obtain more robust results, the random-effects model and the Hartung-Knapp-Sidik-Jonkman method were selected to assess pooled data. Metaregression analysis and sensitivity analysis were performed to explore heterogeneity, and publication bias was assessed by a visual inspection of funnel plots and the AS-Thompson test. RESULTS Eight RCTs with a total of 1,587 participants were identified from the search strategy. Compared with conventional footwear, special therapeutic footwear significantly reduced the incidence of DFU (RR 0.49; 95% CI, 0.28-0.84), with no evidence of publication bias (P = 0.69). Unexpectedly, the effectiveness of special therapeutic footwear had a reverse correlation with the intervention time (coefficient = 0.085, P < 0.05) in the metaregression analysis. CONCLUSION Special therapeutic footwear with offloading properties is effective in reducing the incidence of DFU. However, the effect may decrease gradually over time. Despite undefined reasons, the optimal utility time and renewal frequency of special therapeutic footwear should be considered.

Abstract
BACKGROUND Diabetes-related foot ulcers give rise to considerable morbidity, generate a high monetary cost for health and social care services and precede the majority of diabetes-related lower extremity amputations. There are many clinical prediction rules in existence to assess risk of foot ulceration but few have been subject to validation. OBJECTIVES Our objectives were to produce an evidence-based clinical pathway for risk assessment and management of the foot in people with diabetes mellitus to estimate cost-effective monitoring intervals and to perform cost-effectiveness analyses and a value-of-information analysis. DESIGN We developed and validated a prognostic model using predictive modelling, calibration and discrimination techniques. An overview of systematic reviews already completed was followed by a review of randomised controlled trials of interventions to prevent foot ulceration in diabetes mellitus. A review of the health economic literature was followed by the construction of an economic model, an analysis of the transitional probability of moving from one foot risk state to another, an assessment of cost-effectiveness and a value-of-information analysis. INTERVENTIONS The effects of simple and complex interventions and different monitoring intervals for the clinical prediction rules were evaluated. MAIN OUTCOME MEASURE The main outcome was the incidence of foot ulceration. We compared the new clinical prediction rules in conjunction with the most effective preventative interventions at different monitoring intervals with a 'treat-all' strategy. DATA SOURCES Data from an electronic health record for 26,154 people with diabetes mellitus in one Scottish health board were used to estimate the monitoring interval. The Prediction Of Diabetic foot UlcerationS (PODUS) data set was used to develop and validate the clinical prediction rule. REVIEW METHODS We searched for eligible randomised controlled trials of interventions using search strategies created for Ovid® (Wolters Kluwer, Alphen aan den Rijn, the Netherlands), MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials. Randomised controlled trials in progress were identified via the International Standard Randomised Controlled Trial Number Registry and systematic reviews were identified via PROSPERO. Databases were searched from inception to February 2019. RESULTS The clinical prediction rule was found to accurately assess the risk of foot ulceration. Digital infrared thermometry, complex interventions and therapeutic footwear with offloading devices were found to be effective in preventing foot ulcers. The risk of developing a foot ulcer did not change over time for most people. We found that interventions to prevent foot ulceration may be cost-effective but there is uncertainty about this. Digital infrared thermometry and therapeutic footwear with offloading devices may be cost-effective when used to treat all people with diabetes mellitus regardless of their ulcer risk. LIMITATIONS The threats to the validity of the results in some randomised controlled trials in the review and the large number of missing data in the electronic health record mean that there is uncertainty in our estimates. CONCLUSIONS There is evidence that interventions to prevent foot ulceration are effective but it is not clear who would benefit most from receiving the interventions. The ulceration risk does not change over an 8-year period for most people with diabetes mellitus. A change in the monitoring interval from annually to every 2 years for those at low risk would be acceptable. FUTURE WORK RECOMMENDATIONS Improving the completeness of electronic health records and sharing data would help improve our knowledge about the most clinically effective and cost-effective approaches to prevent foot ulceration in diabetes mellitus.

Abstract
AIMS/HYPOTHESIS Foot ulceration is a serious complication for people with diabetes that results in high levels of morbidity for individuals and significant costs for health and social care systems. Nineteen systematic reviews of preventative interventions have been published, but none provides a reliable numerical summary of treatment effects. The aim of this study was to systematically review the evidence from RCTs and, where possible, conduct meta-analyses to make the best possible use of the currently available data. METHODS We conducted a systematic review and meta-analysis of RCTs of preventative interventions for foot ulceration. OVID MEDLINE and EMBASE were searched to February 2019 and the Cochrane Central Register of Controlled Trials to October 2018. RCTs of interventions to prevent foot ulcers in people with diabetes who were free from foot ulceration at trial entry were included. Two independent reviewers read the full-text articles and extracted data. The quality of trial reporting was assessed using the Cochrane Risk of Bias tool. The primary outcome of foot ulceration was summarised using pooled relative risks in meta-analyses. RESULTS Twenty-two RCTs of eight interventions were eligible for analysis. One trial of digital silicone devices (RR 0.07 [95% CI 0.01, 0.55]) and meta-analyses of dermal infrared thermometry (RR 0.41 [95% CI 0.19, 0.86]), complex interventions (RR 0.59 [95% CI 0.38, 0.90], and custom-made footwear and offloading insoles (RR 0.53 [95% CI 0.33, 0.85]) showed beneficial effects for these interventions. CONCLUSIONS/INTERPRETATION Four interventions were identified as being effective in preventing foot ulcers in people with diabetes, but uncertainty remains about what works and who is most likely to benefit.

Abstract
BACKGROUND Assistive products are items which allow older people and people with disabilities to be able to live a healthy, productive and dignified life. It has been estimated that approximately 1.5% of the world's population need a prosthesis or orthosis. OBJECTIVE The objective of this study was to systematically identify and review the evidence from randomized controlled trials assessing effectiveness and cost-effectiveness of prosthetic and orthotic interventions. METHODS Literature searches, completed in September 2015, were carried out in fourteen databases between years 1995 and 2015. The search results were independently screened by two reviewers. For the purpose of this manuscript, only randomized controlled trials which examined interventions using orthotic or prosthetic devices were selected for data extraction and synthesis. RESULTS A total of 342 randomised controlled trials were identified (319 English language and 23 non-English language). Only 4 of these randomised controlled trials examined prosthetic interventions and the rest examined orthotic interventions. These orthotic interventions were categorised based on the medical conditions/injuries of the participants. From these studies, this review focused on the medical condition/injuries with the highest number of randomised controlled trials (osteoarthritis, fracture, stroke, carpal tunnel syndrome, plantar fasciitis, anterior cruciate ligament, diabetic foot, rheumatoid and juvenile idiopathic arthritis, ankle sprain, cerebral palsy, lateral epicondylitis and low back pain). The included articles were assessed for risk of bias using the Cochrane Risk of Bias tool. Details of the clinical population examined, the type of orthotic/prosthetic intervention, the comparator/s and the outcome measures were extracted. Effect sizes and odds ratios were calculated for all outcome measures, where possible. CONCLUSIONS At present, for prosthetic and orthotic interventions, the scientific literature does not provide sufficient high quality research to allow strong conclusions on their effectiveness and cost-effectiveness.

Evidence based review of literature on detriments to healing of diabetic foot ulcers. Foot Ankle Surg 2017; 23:215-224. [PMID: 29202978 DOI: 10.1016/j.fas.2016.04.002] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2015] [Accepted: 04/15/2016] [Indexed: 02/08/2023]
Abstract
BACKGROUND Diabetes mellitus places a substantial burden on society worldwide. Diabetic foot ulcers are a challenging problem for clinicians. Seven generally accepted detriments to healing of diabetic foot ulcers were identified: infection, glycaemic control, vascular supply, smoking, nutrition, deformity and offloading. The aim of this paper is to present a comprehensive evidence based review of the literature available on detriments to healing of diabetic foot ulcers. METHOD A research question was generated for each of the detriments to healing and a comprehensive review of the literature was performed using the Pubmed database in July 2014. All articles were assessed for relevancy and a level of evidence was assigned. An analysis of the total body of literature was used to assign a grade of recommendation to each detriment. RESULTS Grade A recommendation was assigned to offloading as there was good evidence supporting this intervention. Grade B recommendation was assigned to deformity as there was fair evidence consistent with the hypothesis. Infection and vascular supply had poor quality evidence supporting the research question and grade C recommendation was assigned. Grade I recommendation was assigned to glycaemic control, smoking and nutrition as there was insufficient and conflicting evidence available. CONCLUSION Our literature review revealed good evidence for some factors and insufficient literature on others. Further studies are needed to provide quality evidence regarding detriments to healing of diabetic ulcers.

Abstract
BACKGROUND Foot and ankle devices are being developed as a method of preventing people with sensory perception loss sustaining a fall. Such devices are believed to work by reducing the likelihood of a fall by improving the balance and gait of the user. OBJECTIVES The objective of the review was to evaluate the effectiveness of foot and ankle devices for the prevention of falls and the improvement of balance and gait in adults with sensory perception loss. INCLUSION CRITERIA TYPES OF PARTICIPANTS Participants were community-dwelling adults with bilateral pathological sensory perception loss. TYPES OF INTERVENTION(S)/PHENOMENA OF INTEREST The current review evaluated any foot or ankle device, including but not restricted to, all types of footwear (therapeutic and retail), insoles (customized and prefabricated) and ankle-foot orthoses (AFOs). TYPES OF STUDIES In the absence of randomized controlled trials (RCT), the review considered experimental and epidemiological study designs, except case series, individual case reports and descriptive cross-sectional studies. OUTCOMES The primary outcome was number of falls. Secondary outcome measures were clinical or laboratory measures of balance or gait. SEARCH STRATEGY A search for published and unpublished literature from inception to March 2015 written in the English language was conducted across a number of major electronic databases. A three-step search strategy was developed using MeSH terminology and keywords to ensure all that relevant materials are captured. METHODOLOGICAL QUALITY Methodological quality of included studies was assessed by two reviewers, who appraised each study independently, using standardized Joanna Briggs Institute (JBI) critical appraisal tools. DATA EXTRACTION Quantitative data were extracted from the studies that were identified as meeting the criteria for methodological quality using the standardized JBI data extraction tools. DATA SYNTHESIS Due to the heterogeneity of populations, interventions and outcome measures, meta-analyses were not possible and results are presented in narrative form. RESULTS Nine trials (from 10 papers) involving 238 participants, (14 with multiple sclerosis and 16 with idiopathic peripheral neuropathy, 150 with diabetic neuropathy) and 58 controls were included in the review. No study reported falls as an outcome measure. The results of the included studies found that in people with sensory perception loss, postural sway improved with vibrating insoles and AFO, altering the softness and texture of the top cover had no effect on postural sway, wearing footwear over long distances or AFOs improved step-to-step consistency, and no foot and ankle device was reported to have a negative effect on the balance or gait of people with sensory perception loss. The methodological quality of the included studies was poor. No study used a randomized controlled trial (RCT) methodology. No study incorporated a follow-up period or tested the intervention within the context of the intended clinical environment. CONCLUSION There is limited evidence to suggest that footwear and insole devices can artificially alter postural stability and may reduce the step-to-step variability in adults with sensory perception loss. Varying the material properties of an insole does not notably affect static balance or gait.

Comparison of Removable and Irremovable Walking Boot to Total Contact Casting in Offloading the Neuropathic Diabetic Foot Ulceration. Foot Ankle Int 2016; 37:855-61.

Abstract
BACKGROUND Despite its efficacy in healing neuropathic diabetic foot ulcers (DFUs), total contact cast (TCC) is often underused because of technical limitations and poor patient acceptance. We compared TCC to irremovable and removable commercially available walking boots for DFU offloading. METHODS We prospectively studied 60 patients with DFUs, randomly assigned to 3 different offloading modalities: TCC (group A), walking boot rendered irremovable (i-RWD; group B), and removable walking boot (RWD; group C). Patients were followed up weekly for 90 days or up to complete re-epithelization; ulcer survival, healing time, and ulcer size reduction (USR) were considered for efficacy, whereas number of adverse events was considered for safety. Patients' acceptance and costs were also evaluated. RESULTS Mean healing time in the 3 groups did not differ (P = .5579), and survival analysis showed no difference between the groups (logrank test P = .8270). USR from baseline to the end of follow-up was significant (P < .01) in all groups without differences between the groups. Seven patients in group A (35%), 2 in group B (10%), and 1 in group C (5%) (Fisher exact test P = .0436 group A vs group C) reported nonsevere adverse events. Patients' acceptance and costs were significantly better in group C (P < .05). CONCLUSIONS Our results suggest that a walking boot was as effective and safe as TCC in offloading the neuropathic DFUs, irrespective of removability. The better acceptability and lesser costs of a removable device may actually extend the possibilities of providing adequate offloading. LEVEL OF EVIDENCE Level II, prospective comparative study.

Cochrane Database Syst Rev 2016; 2016:CD006899. [PMID: 27223580 PMCID: PMC9308064 DOI: 10.1002/14651858.cd006899.pub3] [Citation(s) in RCA: 106] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/17/2022]
Abstract
BACKGROUND Autologous platelet-rich plasma (PRP) is a treatment that contains fibrin and high concentrations of growth factors with the potential to improve the healing of chronic wounds. This is the first update of a review first published in 2012. OBJECTIVES To determine whether autologous PRP promotes the healing of chronic wounds. SEARCH METHODS In June 2015, for this first update, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library): Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. We also searched for ongoing and unpublished clinical trials in the WHO International Clinical Trials Registry Platform (ICTRP) (searched January 2015). We did not impose any restrictions with respect to language, date of publication, or study setting. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared autologous PRP with placebo or alternative treatments for any type of chronic wound in adults. We did not apply any date or language restrictions. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology, including two reviewers independently selecting studies for inclusion, extracting data, and assessing risk of bias. MAIN RESULTS The search identified one new RCT, making a total of 10 included RCTs (442 participants, 42% women). The median number of participants per RCT was 29 (range 10 to 117). Four RCTs recruited people with a range of chronic wounds; three RCTs recruited people with venous leg ulcers, and three RCTs considered foot ulcers in people with diabetes. The median length of treatment was 12 weeks (range 8 to 40 weeks).It is unclear whether autologous PRP improves the healing of chronic wounds generally compared with standard treatment (with or without placebo) (risk ratio (RR) 1.19, 95% confidence interval (CI) 0.95 to 1.50; I(2) = 27%, low quality evidence, 8 RCTs, 391 participants). Autologous PRP may increase the healing of foot ulcers in people with diabetes compared with standard care (with or without placebo) (RR 1.22, 95% CI 1.01 to 1.49; I(2) = 0%, low quality evidence, 2 RCTs, 189 participants). It is unclear if autologous PRP affects the healing of venous leg ulcers (RR 1.02, 95% CI 0.81 to 1.27; I(2) = 0% ). It is unclear if there is a difference in the risk of adverse events in people treated with PRP or standard care (RR 1.05, 95% CI 0.29 to 3.88; I(2) = 0%, low quality evidence from 3 trials, 102 participants). AUTHORS' CONCLUSIONS PRP may improve the healing of foot ulcers associated with diabetes, but this conclusion is based on low quality evidence from two small RCTs. It is unclear whether PRP influences the healing of other chronic wounds. The overall quality of evidence of autologous PRP for treating chronic wounds is low. There are very few RCTs evaluating PRP, they are underpowered to detect treatment effects, if they exist, and are generally at high or unclear risk of bias. Well designed and adequately powered clinical trials are needed.

Abstract
OBJECTIVES To prospectively determine clinical and biochemical characteristics associated with the development of peripheral neuropathy, loss of protective sensation, and foot ulceration in persons with type 2 diabetes mellitus (DM) over 7 years. RESEARCH DESIGN AND METHODS Graded monofilament (MF) testing, vibration perception threshold, and neuropathy symptom questionnaires were undertaken in 206 participants with type 2 DM without peripheral vascular disease or history of foot ulceration and 71 healthy participants without DM at baseline and after 7 years. 6 monthly glycosylated hemoglobin (HbA1c) levels and annual serum lipid profiles were measured during follow-up of those with DM. Incident foot ulceration was recorded at follow-up. RESULTS Taller stature and higher quartiles of serum triglyceride and HbA1c levels were associated with neuropathy at follow-up (p=0.008). Remission of baseline neuropathy was observed in 7 participants at follow-up. 9 participants with type 2 DM developed foot ulcers by the end of the study, only 1 at low risk. Mean HbA1c levels were higher in those who developed foot ulceration (p<0.0001). 1 participant with neuropathy throughout developed a Charcot foot. Failure to perceive 2 or more 2, 4 and 6 g MF stimuli at baseline predicted loss of protective sensation at follow-up. CONCLUSIONS Tall stature and worse metabolic control were associated with progression to neuropathy. Mean HbA1c levels were higher in those who developed foot ulcers. Graded MF testing may enrich recruitment to clinical trials and assignation of high risk for foot ulceration.

Abstract
BACKGROUND Pressure ulcers are areas of localised damage to the skin and underlying tissue caused by pressure or shear. Pressure redistribution devices are used as part of the treatment to reduce the pressure on the ulcer. The anatomy of the heel and the susceptibility of the foot to vascular disease mean that pressure ulcers located there require a particular approach to pressure relief. OBJECTIVES To determine the effects of pressure-relieving interventions for treating pressure ulcers on the heel. SEARCH METHODS In May 2013, for this first update, we searched the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid EMBASE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); and EBSCO CINAHL. No language or publication date restrictions were applied. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared the effects of pressure-relieving devices on the healing of pressure ulcers of the heel. Participants were treated in any care setting. Interventions were any pressure-relieving devices including mattresses and specific heel devices. DATA COLLECTION AND ANALYSIS Both review authors independently reviewed titles and abstracts and selected studies for inclusion. Both review authors independently extracted data and assessed studies for risk of bias. MAIN RESULTS In our original review, only one study met the inclusion criteria. This study (141 participants) compared two mattress systems; however, losses to follow up were too great to permit reliable conclusions. We did not find any further relevant studies during this first update. AUTHORS' CONCLUSIONS This review identified one small study at moderate to high risk of bias which provided no evidence to inform practice. More research is needed.

Abstract
BACKGROUND Foot ulcers in people with diabetes are a prevalent and serious global health issue. Wound dressings are regarded as important components of ulcer treatment, with clinicians and patients having many different types to choose from including hydrocolloid dressings. There is a range of different hydrocolloids available including fibrous-hydrocolloid and hydrocolloid (matrix) dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use. OBJECTIVES To compare the effects of hydrocolloid wound dressings with no dressing or alternative dressings on the healing of foot ulcers in people with diabetes. SEARCH METHODS For this first update, in April 2013, we searched the following databases the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. There were no restrictions based on language or date of publication. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that have compared the effects on ulcer healing of hydrocolloid with alternative wound treatments in the treatment of foot ulcers in people with diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS We included five studies (535 participants) in the review: these compared hydrocolloids with basic wound contact dressings, foam dressings, alginate dressings and a topical treatment. Meta-analysis of two studies indicated no statistically significant difference in ulcer healing between fibrous-hydrocolloids and basic wound contact dressings: risk ratio 1.01 (95% CI 0.74 to 1.38). One of these studies found that a basic wound contact dressing was more cost-effective than a fibrous-hydrocolloid dressing. One study compared a hydrocolloid-matrix dressing with a foam dressing and found no statistically significant difference in the number of ulcers healed. There was no statistically significant difference in healing between an antimicrobial (silver) fibrous-hydrocolloid dressing and standard alginate dressing; an antimicrobial dressing (iodine-impregnated) and a standard fibrous hydrocolloid dressing or a standard fibrous hydrocolloid dressing and a topical cream containing plant extracts. AUTHORS' CONCLUSIONS Currently there is no research evidence to suggest that any type of hydrocolloid wound dressing is more effective in healing diabetic foot ulcers than other types of dressing or a topical cream containing plant extracts. Decision makers may wish to consider aspects such as dressing cost and the wound management properties offered by each dressing type e.g. exudate management.

Abstract
BACKGROUND Foot ulcers in people with diabetes are a prevalent and serious global health issue. Dressings form a key part of ulcer treatment, with clinicians and patients having many different types to choose from including hydrogel dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use. OBJECTIVES To assess the effects of hydrogel wound dressings compared with alternative dressings or none on the healing of foot ulcers in people with diabetes. SEARCH METHODS For this first update, in April 2013, we searched the following databases the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. There were no restrictions based on language or date of publication. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that have compared the effects on ulcer healing of hydrogel with alternative wound dressings or no dressing in the treatment of foot ulcers in people with diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS We included five studies (446 participants) in this review. Meta analysis of three studies comparing hydrogel dressings with basic wound contract dressings found significantly greater healing with hydrogel: risk ratio (RR) 1.80, 95% confidence interval (CI) 1.27 to 2.56. The three pooled studies had different follow-up times (12 weeks, 16 weeks and 20 weeks) and also evaluated ulcers of different severities (grade 3 and 4; grade 2 and grade unspecified). One study compared a hydrogel dressing with larval therapy and found no statistically significant difference in the number of ulcers healed and another found no statistically significant difference in healing between hydrogel and platelet-derived growth factor. There was also no statistically significant difference in number of healed ulcers between two different brands of hydrogel dressing. All included studies were small and at unclear risk of bias and there was some clinical heterogeneity with studies including different ulcer grades. No included studies compared hydrogel with other advanced wound dressings. AUTHORS' CONCLUSIONS There is some evidence to suggest that hydrogel dressings are more effective in healing (lower grade) diabetic foot ulcers than basic wound contact dressings however this finding is uncertain due to risk of bias in the original studies. There is currently no research evidence to suggest that hydrogel is more effective than larval therapy or platelet-derived growth factors in healing diabetic foot ulcers, nor that one brand of hydrogel is more effective than another in ulcer healing. No RCTs comparing hydrogel dressings with other advanced dressing types were found.

Abstract
AIM Footwear interventions are used within clinical practice in an effort to reduce ulcerations however the effectiveness of these interventions is unclear. The aim of this paper was to conduct a systematic review which examined the effectiveness of footwear as an intervention for prevention of diabetic foot ulcers or the reduction of biomechanical risk factors for ulceration and to discuss the quality and interpret the findings of research to date. METHODS The CINAHL, Medline and Cochrane Register of Controlled Trials databases were searched with 12 articles identified for review. RESULTS The majority of these studies were cross sectional and examined the effect of different footwear conditions on plantar pressure measurements. Factors which influenced study findings such as participant selection, measurement and analysis techniques, footwear design and compliance are discussed and recommendations for future studies are provided. CONCLUSIONS No research to date has examined the effectiveness of footwear in preventing ulceration. Conflicting findings are reported on the effective of footwear interventions to prevent reulceration. While the use of rocker sole footwear and custom orthoses in plantar pressure reduction are supported in cross sectional studies, longitudinal studies are required to confirm their benefit.

Abstract
BACKGROUND Foot ulcers in people with diabetes mellitus are a common and serious global health issue. Dressings form a key part of ulcer treatment, with clinicians and patients having many different types to choose from including alginate dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use. OBJECTIVES To compare the effects of alginate wound dressings with no wound dressing or alternative dressings on the healing of foot ulcers in people with diabetes mellitus. SEARCH METHODS For this first update, in April 2013, we searched the following databases the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. There were no restrictions based on language or date of publication. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that have compared the effects on ulcer healing of alginate dressings with alternative wound dressings or no dressing in the treatment of foot ulcers in people with diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS We included six studies (375 participants) in this review; these compared alginate dressings with basic wound contact dressings, foam dressings and a silver-containing, fibrous-hydrocolloid dressing. Meta analysis of two studies found no statistically significant difference between alginate dressings and basic wound contact dressings: risk ratio (RR) 1.09 (95% CI 0.66 to 1.80). Pooled data from two studies comparing alginate dressings with foam dressings found no statistically significant difference in ulcer healing (RR 0.67, 95% CI 0.41 to 1.08). There was no statistically significant difference in the number of diabetic foot ulcers healed when an anti-microbial (silver) hydrocolloid dressing was compared with a standard alginate dressing (RR 1.40, 95% CI 0.79 to 2.47). All studies had short follow-up times (six to 12 weeks), and small sample sizes. AUTHORS' CONCLUSIONS Currently there is no research evidence to suggest that alginate wound dressings are more effective in healing foot ulcers in people with diabetes than other types of dressing however many trials in this field are very small. Decision makers may wish to consider aspects such as dressing cost and the wound management properties offered by each dressing type e.g. exudate management.

Abstract
PURPOSE The purpose of this cohort study was to evaluate the effect of a 1-year intervention of an electronic medical record wound care template on the completeness of wound care documentation and medical coding compared to a similar time interval for the fiscal year preceding the intervention. METHODS From October 1, 2006, to September 30, 2007, a "good wound care" intervention was implemented at a rural Veterans Affairs facility to prevent amputations in veterans with diabetes and foot ulcers. The study protocol included a template with foot ulcer variables embedded in the electronic medical record to facilitate data collection, support clinical decision making, and improve ordering and medical coding. RESULTS The intervention group showed significant differences in complete documentation of good wound care compared to the historic control group (χ = 15.99, P < .001), complete documentation of coding for diagnoses and procedures (χ = 30.23, P < .001), and complete documentation of both good wound care and coding for diagnoses and procedures (χ = 14.96, P < .001). CONCLUSIONS An electronic wound care template improved documentation of evidence-based interventions and facilitated coding for wound complexity and procedures.

Abstract
BACKGROUND Diabetes-related foot ulceration is a major contributor to morbidity in diabetes. Diabetic foot ulcers are partly a consequence of abnormal foot pressures and pressure relief is a widely used treatment for healing diabetes-related plantar foot ulcers, but the most effective method for healing is unclear. OBJECTIVES To determine the effects of pressure-relieving interventions on the healing of foot ulcers in people with diabetes. SEARCH METHODS For this update we searched the Cochrane Wounds Group Specialised Register (searched 2 November 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 10); Ovid MEDLINE (1950 to October Week 4 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, October 31, 2012); Ovid EMBASE (1980 to 2012 Week 43); and EBSCO CINAHL (1982 to 1 November 2012). There were no restrictions based on language or publication status. SELECTION CRITERIA Randomised controlled trials evaluating the effects of pressure-relieving interventions on the healing of foot ulcers in people with diabetes. DATA COLLECTION AND ANALYSIS Data from eligible trials were extracted, and summarised using a data extraction sheet, by two review authors independently. MAIN RESULTS Fourteen trials (709 participants) met the inclusion criteria for the review. One study compared two different types of non-removable casts with no discernable difference between the groups. Seven studies (366 participants) compared non-removable casts with removable pressure-relieving devices. In five of those studies non-removable casts were associated with a statistically significant increase in the number of ulcers healed compared with the removable device (RR 1.17 95% CI 1.01 to 1.36: P value = 0.04).Two studies (98 participants) found that significantly more ulcers healed with non-removable casts than with dressings alone. Achilles tendon lengthening combined with a non-removable cast in one study resulted in significantly more healed ulcers at 7 months than non-removable cast alone (RR 2.23; 95% CI 1.32 to 3.76). More ulcers remained healed at two years in this group (RR 3.41; 95% CI 1.42 to 8.18).Other comparisons included surgical debridement of ulcers; felt fitted to the foot; felted foam dressings and none of these showed a statistically significant treatment effect in favour of the intervention. AUTHORS' CONCLUSIONS Non-removable, pressure-relieving casts are more effective in healing diabetes related plantar foot ulcers than removable casts, or dressings alone. Non-removable devices, when combined with Achilles tendon lengthening were more successful in one forefoot ulcer study than the use of a non-removable cast alone.

Abstract
UNLABELLED BACKGROUND Neuropathic diabetic foot ulceration may be prevented if the mechanical stress transmitted to the plantar tissues is reduced. Insole therapy is one practical method commonly used to reduce plantar loads and ulceration risk. The type of insole best suited to achieve this is unknown. This trial compared custom-made functional insoles with prefabricated insoles to reduce risk factors for ulceration of neuropathic diabetic feet. METHOD A participant-blinded randomised controlled trial recruited 119 neuropathic participants with diabetes who were randomly allocated to custom-made functional or prefabricated insoles. Data were collected at issue and six month follow-up using the F-scan in-shoe pressure measurement system. Primary outcomes were: peak pressure, forefoot pressure time integral, total contact area, forefoot rate of load, duration of load as a percentage of stance. Secondary outcomes were patient perceived foot health (Bristol Foot Score), quality of life (Audit of Diabetes Dependent Quality of Life). We also assessed cost of supply and fitting. Analysis was by intention-to-treat. RESULTS There were no differences between insoles in peak pressure, or three of the other four kinetic measures. The custom-made functional insole was slightly more effective than the prefabricated insole in reducing forefoot pressure time integral at issue (27% vs. 22%), remained more effective at six month follow-up (30% vs. 24%, p=0.001), but was more expensive (UK £656 vs. £554, p<0.001). Full compliance (minimum wear 7 hours a day 7 days per week) was reported by 40% of participants and 76% of participants reported a minimum wear of 5 hours a day 5 days per week. There was no difference in patient perception between insoles. CONCLUSION The custom-made insoles are more expensive than prefabricated insoles evaluated in this trial and no better in reducing peak pressure. We recommend that where clinically appropriate, the more cost effective prefabricated insole should be considered for use by patients with diabetes and neuropathy.

Abstract
BACKGROUND Autologous platelet-rich plasma (PRP) is a treatment that contains fibrin and high concentrations of growth factors and has the potential to aid wound healing. OBJECTIVES To determine whether autologous PRP promotes the healing of chronic wounds. SEARCH METHODS We searched the Cochrane Wounds Group Specialised Register (searched 15 August 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 8); Ovid MEDLINE (1950 to August Week 1 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, August 14, 2012); Ovid EMBASE (1980 to 2012 Week 32); EBSCO CINAHL (1982 to 10 August 2012) and International Clinical Trials Registry Platform (ICTRP)(accessed 22 August 2012). No date or language restrictions were applied. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared autologous PRP with placebo or alternative treatments for any type of chronic wound in adults. DATA COLLECTION AND ANALYSIS Two review authors independently assessed each study against the inclusion criteria, extracted data and assessed risk of bias for all included trials. We calculated the risk ratio (RR) or the mean difference (MD) and time to wound healing was analysed as survival data using the hazard ratio (HR). We considered heterogeneity as significant when I(2) was >75%. MAIN RESULTS Nine eligible RCTs were included, with a total of 325 participants of whom 44% were women. The median number of participants per RCT was 26 (range 10 to 86). Four RCTs recruited people with mixed chronic wounds (there were participants with wounds caused by more than one aetiology and participants who had wounds of several aetiologies in the same trial), three RCTs recruited people with venous leg ulcers and two RCTs considered foot ulcers in people with diabetes. The median length of treatment was 12 weeks (range eight to 40 weeks).One study was at low risk of bias, three studies were at high risk of bias with the remainder being at overall unclear risk of bias. The proportion of completely healed chronic wounds was reported in seven RCTs that compared PRP with standard treatment or placebo, with no statistically significant difference between the groups, in diabetic foot ulcers (RR 1.16; 95% CI 0.57 to 2.35), in venous leg ulcers (pooled RR 1.02; 95% CI 0.81 to 1.27; I(2)=0% ) and in mixed chronic wounds (pooled RR 1.85; 95% CI 0.76 to 4.51; I(2)=42%). The total area epithelialised at the end of the intervention was reported in three RCTs of mixed chronic wounds, there was no statistically significant difference between the groups (pooled MD -1.94 cm(2); 95% CI -4.74 to 0.86; I(2)=47%). The percentage of wound area healed was reported in two RCTs of mixed chronic wounds, and results were statistically significant in favour of the PRP group (RR 51.78%; 95% CI 32.70 to 70.86; I(2)= 0%). Wound complications like infection or necrosis were reported by three RCTs, and there was no statistically significant difference between groups (RR 1.08; 95% CI 0.31 to 3.73). Adverse effects were reported by three studies and there was no statistically significant difference between people treated with PRP and those not given PRP (pooled RR 1.07; 95% CI 0.32 to 3.58; I(2)=0%). AUTHORS' CONCLUSIONS There is currently no evidence to suggest that autologous PRP is of value for treating chronic wounds. However, current evidence is based on a small number of RCTs, most of which are either at high or unclear risk of bias. Well-designed and adequately powered clinical trials are needed.

Abstract
Hyaluronic acid (HA) is a polysaccharide common to most species and is found in many sites in the human body, including the skin and soft tissue. A systematic review of the literature and meta-analysis was performed to identify randomized controlled trials, evaluating the use of HA derivatives in healing burns, epithelial surgical, and chronic wounds. Nine studies were identified, which met the search criteria and clinical endpoints of complete healing and percent wound size reduction when using HA vs. either an active or passive comparator. It was found in the vast majority of randomized controlled trials (eight of nine) that HA derivatives significantly improved the healing of wounds vs. traditional therapies or placebo (either via complete healing or a significant reduction in wound size) occurring from burns, venous insufficiency, diabetes, neuropathic insufficiency, and surgical removal of the epithelial layer (for tattoo removal). In the other remaining trial, one formulation of HA was compared with another, with the higher concentration showing improved application characteristics. Further, it was found in a meta-analysis in subsets of patients with diabetic foot ulcers (neuropathic) that HA derivatives healed these types of wounds significantly faster than standard of care. These studies in aggregate show that HA derivatives accelerate the healing process in burns, epithelial surgical wounds, and chronic wounds.

Abstract
BACKGROUND Foot ulcers in people with diabetes are a prevalent and serious global health issue. Wound dressings are regarded as important components of ulcer treatment, with clinicians and patients having many different types to choose from including hydrocolloid dressings. There is a range of different hydrocolloids available including fibrous-hydrocolloid and hydrocolloid (matrix) dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use. OBJECTIVES To compare the effects of hydrocolloid wound dressings with no dressing or alternative dressings on the healing of foot ulcers in people with diabetes. SEARCH METHODS We searched The Cochrane Wounds Group Specialised Register (searched 4 January 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4); Ovid MEDLINE (1950 to December Week 3 2011); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, January 03, 2012); Ovid EMBASE (1980 to 2011 Week 52); and EBSCO CINAHL (1982 to 30 December 2011). There were no restrictions based on language or date of publication. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that have compared the effects on ulcer healing of hydrocolloid with alternative wound dressings or no dressing in the treatment of foot ulcers in people with diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS We included four studies (511 participants) in the review: these compared hydrocolloids with basic wound contact dressings, foam dressings and alginate dressings. Meta-analysis of two studies indicated no statistically significant difference in ulcer healing between fibrous-hydrocolloids and basic wound contact dressings: risk ratio 1.01 (95% CI 0.74 to 1.38). One of these studies found that a basic wound contact dressing was more cost-effective than a fibrous-hydrocolloid dressing. One study compared a hydrocolloid-matrix dressing with a foam dressing and found no statistically significant difference in the number of ulcers healed. There was no statistically significant difference in healing between an antimicrobial (silver) fibrous-hydrocolloid dressing and standard alginate dressing; or an antimicrobial dressing (iodine-impregnated) and a standard fibrous hydrocolloid dressing. AUTHORS' CONCLUSIONS Currently there is no research evidence to suggest that any type of hydrocolloid wound dressing is more effective in healing diabetic foot ulcers than other types of dressing. Decision makers may wish to consider aspects such as dressing cost and the wound management properties offered by each dressing type e.g. exudate management.

Abstract
OBJECTIVE The objective of this study was to assess the impact of a structured follow-up program on the incidence of diabetic foot ulceration (DFU) in high-risk diabetic patients. RESEARCH DESIGN AND METHODS A total of 1874 diabetic patients referred to the Diabetic Foot Unit of the University of Pisa were ranked based on the ulcerative risk score proposed by the International Consensus on Diabetic Foot. Out of 334 patients (17.8%) with a score ≥2, 298 accepted to participate in this prospective trial and were randomized into 2 groups: group A, which received standard treatment, and group B, in which the patients received, as a part of a structured prevention program, custom-made orthesis and shoes. Incidence of new DFUs was observed for no less than 1 year and in a subset of patients after 3 and 5 years, respectively. Incidence of new DFUs and recurrences were considered as primary endpoints to establish the effectiveness of the program; costs were also compared. RESULTS Among the patients enrolled in this follow-up analysis, 46% had neuropathy and deformities, 20% had previous ulceration, 25% had previous minor amputation, and 9% had neuro-osteoarthropathy. During the first 12-month follow-up, 11.5% of patients in group B developed a DFU compared with 38.6% in group A (P < .0001). In the extended follow-up, the cumulative incidence of ulcer in group B compared with group A was 17.6% versus 61% (P < .0001) after 3 years and 23.5% versus 72% (P < .0001) after 5 years, respectively. The net balance at the end of the follow-up was highly in favor of the prevention program, with a saving of more than €100 000 per year. CONCLUSIONS The implementation of a structured follow-up with the use of orthesis and shoes can reduce the incidence of DFU in diabetic patients who are at high ulcerative risk and its related costs.

Abstract
Foot ulcers and their attendant complications are disquietingly high in people with diabetes, a majority of whom have underlying neuropathy. This review examines the evidence base underpinning the prevention and management of neuropathic diabetic foot ulcers in order to inform best clinical practice. Since it may be impractical to ask patients not to weight-bear at all, relief of pressure through the use of offloading casting devices remains the mainstay for management of neuropathic ulcers, whilst provision of appropriate footwear is essential in ulcer prevention. Simple non-surgical debridement and application of hydrogels are both effective in preparing the wound bed for healthy granulation and therefore enhancing healing. Initial empirical antibiotic therapy for infected ulcers should cover the most common bacterial flora. There is limited evidence supporting the use of adjunctive therapies such as hyperbaric oxygen and cytokines or growth factors. In selected cases, recombinant human platelet-derived growth factor has been shown to enhance healing; however, its widespread use cannot be advised due to the availability of more cost-effective approaches. While patient education may be beneficial, the evidence base remains thin and conflicting. In conclusion, best management of foot ulcers is achieved by what is taken out of the foot (pressure, callus, infection, and slough) rather than what is put on the foot (adjuvant treatment).

Abstract
Heel ulceration, on average, costs 1.5 times more than metatarsal ulceration. The aim of this study was to analyze the determinant factors of healing in diabetic patients with heel ulcers and the late outcomes at Jabir Abu Eliz Diabetic Centre Khartoum, Khartoum, Sudan. Data were collected prospectively for 96 of 100 diabetic patients presenting with heel ulcers at the Jabir Abu Eliz Diabetic Centre Khartoum from May 2003 to January 2005. Late outcome was assessed 3 years later (February 2008). Heeling was achieved in one half of the patients (n = 48). In the remaining 48 patients, 22 ended with major lower extremity amputation and 22 were still receiving wound care. A total of 8 patients died, 4 in each group, the healed and unhealed. The most significant determinants of healing using a logistic multivariate regression model, 95% confidence intervals, and odds ratios included a shorter duration of diabetes (p < .009), adequate lower limb perfusion (p < .043), and a superficial foot ulcer (p < .012). Three years later, of the 88 patients who could be traced, 78 were alive and 59 had healed ulcers (7 had died of unrelated causes and 3 of diabetic-related complications), and no additional lower extremity amputation was recorded. Mortality in the series was 18 patients, of whom 14 had undergone a previous lower extremity amputation. Superficial heel ulcers in diabetic patients with a short history of diabetes and with good limb circulation are more likely to heal within an average duration of 25 weeks. At 3 years of follow-up, 75% showed a favorable outcome for ulcer healing, and 22 patients underwent lower extremity amputation (25%), of whom 14 were dead within 3 years.

Abstract
BACKGROUND Pressure ulcers are areas of localised damage to the skin and underlying tissue caused by pressure or shear. Pressure redistribution devices are used as part of the treatment to reduce the pressure on the ulcer. The anatomy of the heel and the susceptibility of the foot to vascular disease mean that pressure ulcers located there require a particular approach to pressure relief. OBJECTIVES To determine the effects of pressure-relieving interventions for treating pressure ulcers on the heel. SEARCH STRATEGY We searched the Cochrane Wounds Group Specialised Register (searched 25 March 2011); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 1); Ovid MEDLINE (1948 to March Week 3 2011); Ovid EMBASE (1980 to 2011 Week 12);Ovid MEDLINE (In-Process & Other Non-Indexed Citations March 29, 2011); and EBSCO CINAHL (1982 to 25 March 2011). We applied no language or publication date restrictions. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared the effects of pressure-relieving devices on the healing of pressure ulcers of the heel. Participants were treated in any care setting. Interventions were any pressure-relieving devices including mattresses and specific heel devices. DATA COLLECTION AND ANALYSIS Both review authors independently reviewed titles and abstracts and selected studies for inclusion. Both review authors independently extracted data and assessed studies for risk of bias. MAIN RESULTS One study met the inclusion criteria. This study (141 participants) compared two mattress systems however losses to follow up were too great to permit reliable conclusions. AUTHORS' CONCLUSIONS This review identified one small study at moderate to high risk of bias which provided no evidence to inform practice. More research is needed.

Abstract
BACKGROUND Foot ulcers in people with diabetes are a prevalent and serious global health issue. Dressings form a key part of ulcer treatment, with clinicians and patients having many different types to choose from including hydrogel dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use. OBJECTIVES To assess the effects of hydrogel wound dressings compared with alternative dressings or none on the healing of foot ulcers in people with diabetes. SEARCH STRATEGY We searched the Cochrane Wounds Group Specialised Register (searched 10 June 2011); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 2); Ovid MEDLINE (1950 to June Week 1 2011); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, June 8, 2011); Ovid EMBASE (1980 to 2011 Week 22) and EBSCO CINAHL (1982 to 3 June 2011). There were no restrictions based on language or date of publication. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that have compared the effects on ulcer healing of hydrogel with alternative wound dressings or no dressing in the treatment of foot ulcers in people with diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS We included five studies (446 participants) in this review. Meta analysis of three studies comparing hydrogel dressings with basic wound contract dressings found significantly greater healing with hydrogel: risk ratio (RR) 1.80, 95% confidence interval (CI) 1.27 to 2.56. The three pooled studies had different follow-up times (12 weeks, 16 weeks and 20 weeks) and also evaluated ulcers of different severities (grade 3 and 4; grade 2 and grade unspecified). One study compared a hydrogel dressing with larval therapy and found no statistically significant difference in the number of ulcers healed and another found no statistically significant difference in healing between hydrogel and platelet-derived growth factor. There was also no statistically significant difference in number of healed ulcers between two different brands of hydrogel dressing. All included studies were small and at unclear risk of bias and there was some clinical heterogeneity with studies including different ulcer grades. No included studies compared hydrogel with other advanced wound dressings. AUTHORS' CONCLUSIONS There is some evidence to suggest that hydrogel dressings are more effective in healing (lower grade) diabetic foot ulcers than basic wound contact dressings however this finding is uncertain due to risk of bias in the original studies. There is currently no research evidence to suggest that hydrogel is more effective than larval therapy or platelet-derived growth factors in healing diabetic foot ulcers, nor that one brand of hydrogel is more effective than another in ulcer healing. No RCTs comparing hydrogel dressings with other advanced dressing types were found.

Abstract
BACKGROUND Frequent use of walking boots in podiatric medicine often elicits patient complaints and sequelae from the imposed limb-length discrepancy. This study was designed primarily to determine whether peak plantar pressures are decreased in the contralateral foot when a moderately worn athletic shoe is worn opposite a high-calf walking boot and, if so, secondarily to determine whether a specialized surgical shoe worn on the contralateral foot can also effectively reduce this pressure. The pressure reductions were then compared to determine whether significantly greater plantar pressure reduction was provided by either the athletic shoe or the surgical shoe. METHODS Participants without a foot abnormality walked on a treadmill in four footwear combinations: barefoot bilaterally, high-calf rocker-bottom sole (HCRB) walking boot/ barefoot, HCRB walking boot/athletic shoe, and HCRB walking boot/modified walking boot shoe. Measurements were taken with the participants wearing socks. Peak plantar calcaneal pressures were collected. RESULTS Peak plantar pressures under the calcaneus opposite the HCRB walking boot were significantly reduced from barefoot pressures when either an athletic shoe or the modified walking boot shoe was worn. However, no significant difference was seen when comparing the reduction by the athletic shoe with that by the modified walking boot. CONCLUSIONS Wearing an athletic shoe on the foot opposite an HCRB walking boot reduces calcaneal pressures; however, wearing a modified device with structural properties of an HCRB walking boot sole is no better than an athletic shoe at reducing peak calcaneal pressures.

Abstract
Charcot neuroarthropathy is one of the most serious manifestations of the diabetic foot syndrome and the multifaceted disease pattern requires interdisciplinary cooperation. Problems may arise even if the diagnosis is made early and lack of pain may mislead to the assumption of an infectious or traumatic event. With respect to operative therapy the characteristics of polyneuropathy and altered bone metabolism have to be taken into account. Rehabilitation, in particular, differs from the guidelines for trauma patients. In the face of high complication risks substantial improvement of function must be the goal for operative treatment.

Abstract
CONTEXT Ulceration can be a debilitating and costly complication of the neuropathic diabetic foot. Insoles inserted into footwear are routinely used in clinical practice to help to prevent ulceration. AIM AND SCOPE OF THE REVIEW: This review evaluated the effectiveness of insoles used for the prevention of ulcer in the neuropathic diabetic foot. METHODS Databases were searched from inception to 2008, supplemented by hand searching of references and grey literature. Data extraction and methodological quality assessment were independently conducted by two reviewers following the recommendations of the Centre for Reviews and Dissemination. RESULTS A total of five trials met the inclusion criteria: two randomised control trials (RCTs), two case control studies, and one follow-up study. The methodological quality of the majority of studies was poor. Omitted details regarding the generalisability of results made study comparison and inference to practice difficult. There is a small amount of limited evidence indicating that insoles are effective in reducing incidence of ulceration and reducing plantar peak pressures in the diabetic neuropathic foot. No study included economic analysis or patient-based outcome measures. CONCLUSIONS Insoles appear of use for the prevention of neuropathic diabetic foot ulceration, although evidence is limited. Clinical recommendation regarding type and specification of insole is not possible at this time. There is an essential need for a large well-designed RCT comparing different types of commonly used insole for the prevention of ulceration in the diabetic neuropathic foot. Outcome measures should include patient perceptions of the effectiveness and cost-effectiveness analysis.

Abstract
BACKGROUND Foot ulceration is thought to affect 15% of people with diabetes at some time in their lives. Debridement is widely regarded as an effective intervention to speed up ulcer healing. The most effective method is unclear. OBJECTIVES To assess the effects of debridement interventions on the healing of diabetic foot ulcers. SEARCH STRATEGY For this third update we searched the Cochrane Wounds Group Specialised Register (June 2009); The Cochrane Central Register of Controlled Trials (CENTRAL) - The Cochrane Library 2009, Issue 2; Ovid MEDLINE - 1950 to June Week 3 2009; Ovid EMBASE - 1980 to 2009 Week 25 and Ovid CINAHL - 1982 to June Week 3 2009. SELECTION CRITERIA Randomised controlled trials (RCTs) evaluating any method of debriding diabetic foot ulcers and measuring complete healing or rate of healing. There was no restriction on articles/trials based on language or publication status. DATA COLLECTION AND ANALYSIS Data extraction and assessment of study quality were undertaken by one review author and checked by an Editor of the Wounds Group. MAIN RESULTS Six RCTs of debridement were identified: four assessed hydrogels, with an additional study evaluating larval therapy against hydrogel and one evaluated surgical debridement. Pooling the three RCTs which compared hydrogel with gauze or standard care suggested that hydrogels are significantly more effective in healing diabetic foot ulcers (Relative Risk 1.84, 95% Confidence Interval (CI)1.3 to 2.61). Surgical debridement showed no significant benefit over standard treatment. One small trial suggested that larvae resulted in a more than 50% reduction in wound area compared with hydrogel. Other debridement methods such as enzyme preparations or polysaccharide beads have not been evaluated in diabetic foot ulcers. AUTHORS' CONCLUSIONS There is evidence to suggest that hydrogel increases the healing rate of diabetic foot ulcers compared with gauze dressings or standard care and larval therapy resulted in significantly greater reduction in wound area than hydrogel. More research is needed to evaluate the effects of a range of widely used debridement methods and of debridement per se.

Vacuum cushioned removable cast walkers reduce foot loading in patients with diabetes mellitus. Gait Posture 2009; 30:11-5.

Abstract
BACKGROUND Diabetes mellitus is one of the most common diseases worldwide and the number of patients is expected to increase dramatically in future. Plantar ulceration is partly caused by high plantar pressures and a major complication in diabetic patients. PURPOSE The aim of this study was to investigate the pressure-relieving effects of two vacuum orthoses in patients with diabetes mellitus. METHODS Twenty patients with diabetes mellitus were included. They presented with plantar callosities but no ulceration. Exclusion criteria included the use of walking aids and other systemic diseases. Plantar pressure distribution was measured with sensor insoles (Pedar-X, Novel GmbH) during walking in two vacuum orthoses, a post-operative shoe and an off-the-shelf shoe as reference condition. Statistical analysis was conducted using Friedman and Wilcoxon signed-rank tests. RESULTS Significant differences in plantar pressure distribution were found between the four walking conditions. The contact area increased in the midfoot with the vacuum orthoses. Maximum force and peak pressures showed a significant decrease under the rearfoot and forefoot and increased in the midfoot area during walking with both vacuum orthoses. The high-cut vacuum orthosis revealed equal pressure relief under the forefoot and significantly lower rearfoot pressures compared to the post-operative shoe. CONCLUSIONS The vacuum orthoses demonstrated a comparable pressure-relieving efficacy under the forefoot to post-operative shoes. Using vacuum orthosis significantly benefited re-distribution of plantar pressure and the roll-over process. Clinical significance of the pressure-relieving efficacy could not be confirmed in this investigation and has to be addressed in further studies.

Abstract
Background Foot ulcers are a significant problem for people with diabetes. Comprehensive assessments of risk factors associated with diabetic foot ulcer are recommended in clinical guidelines to decrease complications such as prolonged healing, gangrene and amputations, and to promote effective management. However, the translation of clinical guidelines into nursing practice remains fragmented and inconsistent, and a recent homecare chart audit showed less than half the recommended risk factors for diabetic foot ulcers were assessed, and peripheral neuropathy (the most significant predictor of complications) was not assessed at all. Strong leadership is consistently described as significant to successfully transfer guidelines into practice. Limited research exists however regarding which leadership behaviours facilitate and support implementation in nursing. The purpose of this pilot study is to evaluate the impact of a leadership intervention in community nursing on implementing recommendations from a clinical guideline on the nursing assessment and management of diabetic foot ulcers. Methods Two phase mixed methods design is proposed (ISRCTN 12345678). Phase I: Descriptive qualitative to understand barriers to implementing the guideline recommendations, and to inform the intervention. Phase II: Matched pair cluster randomized controlled trial (n = 4 centers) will evaluate differences in outcomes between two implementation strategies. Primary outcome: Nursing assessments of client risk factors, a composite score of 8 items based on Diabetes/Foot Ulcer guideline recommendations. Intervention: In addition to the organization's 'usual' implementation strategy, a 12 week leadership strategy will be offered to managerial and clinical leaders consisting of: a) printed materials, b) one day interactive workshop to develop a leadership action plan tailored to barriers to support implementation; c) three post-workshop teleconferences. Discussion This study will provide vital information on which leadership strategies are well received to facilitate and support guideline implementation. The anticipated outcomes will provide information to assist with effective management of foot ulcers for people with diabetes. By tracking clinical outcomes associated with guideline implementation, health care administrators will be better informed to influence organizational and policy decision-making to support evidence-based quality care. Findings will be useful to inform the design of future multi-centered trials on various clinical topics to enhance knowledge translation for positive outcomes.

Abstract
BACKGROUND Custom foot orthoses are commonly recommended for the treatment of foot pain. OBJECTIVES To evaluate the effectiveness of custom foot orthoses for different types of foot pain. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 2), MEDLINE (from January 1966), EMBASE (from January 1980), CINAHL (from January 1982) and the Physiotherapy Evidence Database (PEDro) (to June 2007). We also contacted authors of included trials and known researchers in the field and checked the reference lists of included trials to identify trials. No language or publication restrictions were applied. SELECTION CRITERIA Randomised controlled trials and controlled clinical trials evaluating custom-made foot orthoses for any type of foot pain. Outcomes included quantifiable levels of foot pain, function, disability, health-related quality of life, participant satisfaction, adverse effects and compliance. DATA COLLECTION AND ANALYSIS Two authors independently selected trials, rated methodological quality and cross checked data extraction. Data were analysed separately for different diagnoses of foot pain and follow-up time points. MAIN RESULTS Eleven trials involving 1332 participants were included: five trials evaluated custom-made foot orthoses for plantar fasciitis (691 participants); three for foot pain in rheumatoid arthritis (231 participants); and one each for foot pain in pes cavus (154 participants), hallux valgus (209 participants) and juvenile idiopathic arthritis (JIA) (47 participants). Comparisons to custom-made foot orthoses included sham orthoses; no intervention; standardised interventions given to all participants; non-custom (prefabricated) foot orthoses; combined manipulation, mobilisation or stretching; night splints; and surgery. Follow up ranged from one week to three years. Custom-made foot orthoses were effective for painful pes cavus (NNTB:5), rearfoot pain in rheumatoid arthritis (NNTB:4), foot pain in JIA (NNTB:3) and painful hallux valgus (NNTB:6); however, surgery was even more effective for hallux valgus and non-custom foot orthoses appeared just as effective for JIA but the analysis may have lacked sufficient power to detect a difference in effect. It is unclear if custom-made foot orthoses were effective for plantar fasciitis or metatarsophalangeal joint pain in rheumatoid arthritis. Custom-made foot orthoses were a safe intervention in all studies. AUTHORS' CONCLUSIONS There is limited evidence on which to base clinical decisions regarding the prescription of custom-made foot orthoses for the treatment of foot pain. Currently, there is gold level evidence for painful pes cavus and silver level evidence for foot pain in JIA, rheumatoid arthritis, plantar fasciitis and hallux valgus.

Abstract
PURPOSE The purpose of this review was to propose a model that describes the influences on the behavior and psychological functioning of people at risk for diabetes-related foot complications. METHODS A literature search was conducted in Medline (1950-2005), CINAHL (1982-2005), and PsycInfo (1967-2005) databases and in reference lists of journal articles and relevant books. The search focused on published literature in the English language that was related to concepts such as diabetes-related foot complications, behavior, and psychology. RESULTS The literature reviewed was arranged to reflect the reciprocal relationship between the personal, environmental, and behavioral factors of people at risk of diabetes-related foot complications. The model proposed uses the concept of reciprocal determinism to illustrate how these factors interact and influence the development of diabetes-related foot complications. CONCLUSION The concept of reciprocal determinism may be useful when developing further investigation into educational and behavioral interventions in this clinical population.

Abstract
As the incidence of diabetes mellitus is increasing globally, complications related to this endocrine disorder are also mounting. Because of the large number of patients, foot ulcers developing in the feet of diabetics have become a public health problem. The predisposing factors include abnormal plantar pressure points, foot deformities, and minor trauma. Vulnerable feet usually already have vascular insufficiency and peripheral neuropathy. The complex nature of these ulcers deserves special care. The most useful prognostic feature for healing remains the ulcer depth, ulcers heal poorly if they clearly involve underlying tendons, ligament or joints and, particularly, when gangrenous tissue is seen. Local treatment of the ulcer consists of repeated debridement and dressing. No 'miraculous' outcome is expected, even with innovative agents like skin cover synthetics, growth factors and stem cells. Simple surgery like split skin grafting or minor toe amputations may be necessary. Sophisticated surgery like flap coverages are indicated for younger patients. The merits of an intact lower limb with an abnormal foot have to be weighed against amputation and prosthesis in the overall planning of limb salvage or sacrifice. If limb salvage is the decision, additional means like oxygen therapy, and other alternative medicines, might have benefits. The off-loading of footwear should always be a major consideration as a prevention of ulcer formation.

Abstract
The authors use a total contact cast (TCC), Charcot restraint orthotic walker (CROW), or prefabricated diabetic walker (DW) for the treatment of neuroarthropathy, depending on the medical, social, and economic circumstances. There is not one single orthosis for the treatment of Charcot feet, but there are several models with advantages and disadvantages the physician should be aware of. In a retrospective study of 200 Charcot feet, the ankle foot orthosis (AFO) built in the authors' workshop turned out to be an efficient and comfortable appliance for orthotic treatment after reconstructive surgery. They prefer this type of orthosis because of its versatility and its safe application in a compliant patient.
