BACKGROUND: Multiple organizations have issued guidelines to address the prevention, diagnosis and management of diabetic foot ulcers. These guidelines are based on evidence review and expert opinion. <p>METHODS: Literature review was conducted and guidelines were reviewed to identify consensus (or lack thereof) on the nature of these recommendations, the strength of the recommendations and the level of evidence.</p> <p>RESULTS: Most guidelines were not based on highest level of evidence (randomized controlled trials). A listing of recommendations for prevention, diagnosis and management was created with evidence basis for all recommendations.</p> <p>CONCLUSIONS: Areas for future research were identified among recommendations based on minimal evidence, areas of controversy, or in areas of clinical care without recommendations.</p>
We sought to evaluate the relationship between baseline hemoglobin A1c (HbA1c) level and clinical outcomes, including foot ulcer outcome (resolved versus unresolved) and wound-healing time, in individuals with type 2 diabetes.
A prospective observational study was conducted on 99 patients presenting with a diabetic foot ulceration. Patient and ulcer characteristics were recorded. Patients were followed up for a maximum of 1 year.
After 1 year of follow-up, 77% of ulcers healed and 23% did not heal. Although this study demonstrated that the baseline HbA1c reading was not a significant predictor of foot ulcer outcome (P = .603, resolved versus amputated), on further statistical analyses, when HbA1c was compared with the time taken for complete ulcer healing in the resolved group (n = 77), it proved to be significant (P = .009).
These findings have important implications for clinical practice, especially in an outpatient setting. Improving glycemic control may improve ulcer outcomes. Prediction of outcome may be helpful for health-care professionals in individualizing and optimizing clinical assessment and management of patients. Identification of determinants of outcome could result in improved health outcomes, improved quality of life, and fewer diabetes-related foot complications.
We assessed the efficacy of customized foot orthotic therapy by comparing reulceration rates, minor amputation rates, and work and daily living activities before and after therapy. Peak plantar pressures and peak plantar impulses were compared with the patients not wearing and wearing their prescribed footwear.
One hundred seventeen patients with diabetes were prescribed therapeutic insoles and footwear based on the results of a detailed biomechanical study and were followed for 2 years. All of the patients had a history of foot ulcers, but none had undergone previous orthotic therapy.
Before treatment, the reulceration rate was 79% and the amputation rate was 54%. Two years after the start of orthotic therapy, the reulceration rate was 15% and the amputation rate was 6%. Orthotic therapy reduced peak plantar pressures in patients with reulcerations and in those without (P < .05), although a significant decrease in peak plantar impulses was achieved only in patients not experiencing reulceration. Sick leave was reduced from 100% to 26%.
Personalized orthotic therapy targeted at reducing plantar pressures by off-loading protects high-risk patients against reulceration. Treatment reduced the reulceration rate and peak plantar pressures, leading to patients’ return to work or other activities. (J Am Podiatr Med Assoc 103(4): 281-290, 2013)
In a retrospective review of 233 cases of diabetic foot ulceration preceded by minor trauma, 192 ulcerations exhibited focal pressure keratosis as the preceding traumatic event. The frequency of outpatient visits and other foot care interventions were correlated with the occurrence and severity of ulceration. Patients seen more frequently in an outpatient foot clinic had less severe ulcers and were less likely to undergo surgical treatment than those with less frequent visits.

BACKGROUND:Diabetic foot ulceration is a severe complication of diabetes characterized by chronic inflammation and impaired wound healing. This study aims to evaluate the effect of a medical device gel based on Adelmidrol + Trans traumatic acid in the healing process of diabetic foot ulcers. METHODS: Thirty-seven diabetic patients with foot ulcers of mild/moderate grade were treated with the gel applied daily for 4 weeks on the affected area. The following parameters were evaluated at baseline and weekly: a) wound area, measured drawing a map of the ulcer then calculated with Photoshop6 tools, b) clinical appearance of the ulcer, assessed recording the presence/absence of dry/wet necrosis, infection, fibrin, neoepithelium, exudate, redness, granulation tissue. RESULTS: Topical treatment led to progressive healing of diabetic foot ulcers with a significant reduction of the wound area and an improvement in the clinical appearance of the ulcers. No adverse events treatment-related were observed. CONCLUSIONS: The results of this open-label study show the potential benefits of Adelmidrol + Trans traumatic acid topical administration to promote re-epithelialization of diabetic foot ulcers. Further studies need to confirm the observed results.
Both vascular surgeons and podiatric physicians care for patients with diabetic foot ulcerations (DFUs), one of today's most challenging health-care populations in the United States. The prevalence of DFUs has steadily increased, along with the rising costs associated with care. Because of the numerous comorbidities affecting these patients, it is necessary to take a multidisciplinary approach in the management of these patients. Such efforts, primarily led by podiatric physicians and vascular surgeons, have been shown to effectively decrease major limb loss. Establishing an interprofessional partnership between vascular surgery and podiatric medicine can lead to an improvement in the delivery of care and outcomes of this vulnerable patient population.
We conducted a post-hoc retrospective analysis of patients enrolled in a randomized controlled trial to evaluate overall costs of negative pressure wound therapy (NPWT; V.A.C. Therapy; KCI USA, Inc, San Antonio, Texas) versus advanced moist wound therapy (AMWT) in treating grade 2 and 3 diabetic foot wounds during a 12-week therapy course.
Data from two study arms (NPWT [n = 169] or AMWT [n = 166]) originating from Protocol VAC2001-08 were collected from patient records and used as the basis of the calculations performed in our cost analysis.
A total of 324 patient records (NPWT = 162; AMWT = 162) were analyzed. There was a median wound area reduction of 85.0% from baseline in patients treated with NPWT compared to a 61.8% reduction in those treated with AMWT. The total cost for all patients, regardless of closure, was $1,941,472.07 in the NPWT group compared to $2,196,315.86 in the AMWT group. In patients who achieved complete wound closure, the mean cost per patient in the NPWT group was $10,172 compared to $9,505 in the AMWT group; the median cost per 1 cm2 of closure was $1,227 with NPWT and $1,695 with AMWT. In patients who did not achieve complete wound closure, the mean total wound care cost per patient in the NPWT group was $13,262, compared to $15,069 in the AMWT group. The median cost to close 1 cm2 in wounds that didn't heal using NPWT was $1,633, compared to $2,927 with AMWT.
Our results show greater cost effectiveness with NPWT versus AMWT in recalcitrant wounds that didn't close during a 12-week period, due to lower expenditures on procedures and use of health-care resources.
