Effects of neuromuscular taping form I on wound temperature and erythema in diabetic foot ulcer: a preliminary study.

OBJECTIVE: This study aimed to measure the effectiveness of neuromuscular taping (NMT) form I (a polyacrylate tape 0.6cm wide and 30cm long) on wound temperature and erythema in diabetic foot ulcers (DFUs) as an initial study in NMT intervention trials. METHOD: The study employed a quasi-experimental pretest and post-test design with a seven-day observation. The research sample was 38 patients with DFU grades 2 and 3. The sample was divided into two groups: the control group (n=19) and the intervention group (n=19). In wound care, the modern dressing was applied to both groups while NMT was applied to the intervention group in form I with 30cm long and 6mm wide strips, and on the proximal, distal and lateral sides. The wound bed temperature was measured with a non-contact infrared thermometer, and erythema was measured with Corel Photo-Paint X5 software (Corel Corp, Canada). Statistical analysis between the two groups was carried out using the Mann-Whitney test, independent t-test and Chi-squared test with p< 0.05 representing statistical significance. RESULTS: The preliminary results revealed that no statistically significant differences (p>0.05) were noted between the groups in sociodemographic or clinical characteristics, including age, body mass index, blood sugar, duration of diabetes, sex, smoking history, wound temperature and degree of erythema. Finally, it was also observed that, after seven days of application, NMT form I increased wound bed temperature, and reduced the level of erythema (p<0.05). CONCLUSION: In this study, NMT form I has been shown to increase the wound bed temperature and reduce the degree of erythema in DFUs.

Patients' behaviour after referral to a wound care clinic for diabetic foot ulcer care: a grounded theory study.

OBJECTIVE: The aim of this study was to construct a grounded theory regarding patients' activity behaviour over time after referral to an outpatient clinic for diabetic foot ulcer (DFU) care. METHOD: A constructivist grounded theory approach was used. Data from observations of and interviews with participants were collected and analysed using the constant comparative method. Based on this, the grounded theory 'Just a bump in the road' was constructed. RESULTS: The cohort included five participants who considered their ulcers as 'Just a bump in the road' in their lives, and four subcategories were embedded in this core category: 'Restricting my freedom'; 'Trusting or doubting the system'; 'Feeling no pain or illness'; and 'Receiving insufficient information'. Together, these categories describe the participants' behaviour and underlying concerns related to daily activities after referral to an outpatient clinic for the care of their DFU. CONCLUSION: The grounded theory 'Just a bump in the road' describes how participants with a DFU viewed their condition as merely a passing phase that would end with them regaining what they considered a normal life. Integrating these results into clinical practice could lead to improved care and a focus shift among health professionals from viewing patients as being defined by their wounds to seeing them as people who live with a wound.

Lessons learnt from an aggressive tumour masquerading as a neuropathic heel ulcer: a case report.

Cutaneous malignant melanoma (cMM) can develop at any site, but one-third of cases primarily affect the lower extremities, with ankle and foot lesions representing 3-15% of all cases. However, cMM may become a clinical conundrum when it presents as chronic ulceration that is clinically indiscernible from other lower extremity ulcers in patients with diabetes. We present the case of a 71-year-old female patient with a longstanding history of diabetes, hypertension, obesity, chronic kidney disease and heart failure who presented to our hospital with a fungating heel ulcer. The lesion was initially managed in another hospital as a neuropathic diabetic foot ulcer (DFU), treated by multiple local wound debridement. However, the ulcer progressed into a fungating heel lesion that interfered with the patient's mobility and quality of life. Consequently, the patient was referred to our specialist diabetic foot service for further management. Excisional biopsy of the lesion disclosed a cMM. Positron emission tomography/computed-tomography scanning revealed hypermetabolic ipsilateral inguinal lymphadenopathy, and a right cerebral metastasis for which palliative chemotherapy was initiated. Immunotherapy was considered, but the patient died before it was started. Atypical foot ulcers in patients with diabetes warrant a careful diagnostic approach, especially for recalcitrant cutaneous lesions not responding to standard therapies. Conscientious management, without undue delay in obtaining a histopathological diagnosis, might lead to early diagnosis of melanoma and potentially more favourable outcomes. This case highlights the importance of consideration of atypical foot lesions, in general practice in addition to referral centres, to try to identify alarming features and act accordingly.

A prospective, open-label, nonrandomized clinical trial using polyvinyl alcohol antibacterial foam for debridement of diabetic foot ulcers.

BACKGROUND: Diabetic foot ulcers (DFUs) pose significant challenges for patients, often leading to chronic inflammation, reduced mobility, and chronic pain. Despite being less prevalent in the United States compared to other nations, the economic burden of DFUs remains substantial, with an estimated annual cost ranging from $9 billion to $13 billion. Furthermore, DFUs are a leading cause of nontraumatic lower extremity amputations and significantly impact health care systems and work productivity. OBJECTIVE: This study aimed to evaluate the effectiveness of a polyvinyl alcohol (PVA) foam dressing containing gentian violet/methylene blue (GV/MB) in managing chronic DFUs. MATERIALS AND METHODS: A single-center study was conducted involving 20 patients with full-thickness chronic lower extremity wounds, including DFUs. Patients received treatment with a PVA foam dressing with GV/MB applied in an outpatient setting over a period of 4 weeks. Wound size, bacterial presence, and healing progress were assessed using fluorescence imaging and wound measurements. RESULTS: The study included 13 males and 7 females with an average age of 64.2 years. After 4 weeks of treatment, the average DFU size decreased by 53%, with 4 patients achieving complete wound closure. Reduction in ulcer size was strongly correlated with the use of surgical debridement and PVA GV/MB foam. Fluorescence imaging demonstrated a significant reduction in bacterial presence in all patients by the end of the study. Follow-up at 3 and 6 months showed no recurrent ulcerations, indicating the potential for long-term efficacy. CONCLUSION: The findings suggest that PVA GV/MB foam dressings, when combined with surgical debridement, are effective in promoting the healing of chronic DFUs. Further research with larger, controlled studies is warranted to confirm these findings and assess cost-effectiveness.

Use of carbon dioxide fractional laser in the management of lower limb ischemia in patients with diabetes: a case report : CO2 fractional laser in the treatment of diabetic foot.

Treatment of lower limb ischemia in patients with diabetes is challenging because of the location of the ulcers and the complexity of their pathogenesis. Carbon dioxide fractional laser (CO2FL) therapy in conjunction with tibial periosteum distraction could become a substitute for conventional methods. We herein describe a patient diagnosed with ischemic diabetic foot with a complex ulcer in the upper third of the tibia. Laser irradiation (Deep FX mode with 30 mJ of energy and 10% density) was applied to the entire region of skin below the knee after surface anesthesia, and this treatment was performed twice a week until the ulcer healed. Computed tomography angiography showed successful establishment of a blood supply to the back of the right foot after treatment. Skin grafting was successfully performed, with only a few wounds remaining on the foot 8 months after treatment. The pain score was significantly decreased at the last follow-up. No complications occurred. This case report provides guidance for the performance of CO2FL, a fast, easy, accurate treatment in patients with diabetes. CO2FL can target lower limb arterial occlusive disease accompanied by refractory ulcers, addressing the underlying vascular occlusion and dysfunction as well as promoting microcirculation and wound healing.

Clinical perspectives on sampling and processing approaches for the management of infection in diabetic foot ulceration: A qualitative study.

Diabetic foot ulcers (DFUs) often become infected and are treated with antimicrobials, with samples collected to inform care. Swab samples are easier than tissue sampling but report fewer organisms. Compared with culture and sensitivity (C&S) methods, molecular microbiology identifies more organisms. Clinician perspectives on sampling and processing are unknown. We explored clinician perspectives on DFU sampling-tissue samples/wound swabs-and on processing techniques, culture and sensitivity or molecular techniques. The latter provides information on organisms which have not survived transport to the laboratory for culture. We solicited feedback on molecular microbiology reports. Qualitative study using semi-structured interview, with analysis using a Framework approach. CODIFI2 clinicians from UK DFU clinics. Seven consultants agreed to take part. They reported, overall, a preference for tissue samples over swabbing. Clinicians were not confident replacing C&S with molecular microbiology as the approach to reporting was unfamiliar. The study was small and did not recruit any podiatrists or nurses, who may have discipline-specific attitudes or perspectives on DFU care. Both sampling approaches appear to be used by clinicians. Molecular microbiology reports would not be, at present, suitable for replacement of traditional culture and sensitivity.

Acute foot attack in patients with diabetes requires urgent action.

This review summarises the present knowledge of acute foot attacks in patients with diabetes. Diagnosis and treatment of acute foot attacks in patients with diabetes are often delayed, which increases the risk of amputations. To prevent this, urgent action is necessary, as it is for acute myocardial infarction and stroke, to ensure that patients are seen by competent specialists in a multidisciplinary team within hours. By following evidence-based guidelines, such as the National Treatment Guideline for diabetic foot disease from the Danish Endocrine Society, and seeking immediate medical attention, the risk of amputation and complications can be significantly reduced.

Assessment between antiseptic and normal saline for negative pressure wound therapy with instillation and dwell time in diabetic foot infections.

Negative pressure wound therapy with instillation and dwell time (NPWTi-d) is increasingly used for a diverse range of wounds. Meanwhile, the topical wound irrigation solution consisting of polyhexamethylene biguanide and betaine (PHMB-B) has shown efficacy in managing wound infections. However, the effectiveness of this solution as a topical instillation solution for NPWTi-d in patients with diabetic foot infections (DFIs) has not been thoroughly studied. The objective of this retrospective study was to evaluate the impact of using PHMB-B as the instillation solution during NPWTi-d on reducing bioburden and improving clinical outcomes in patients with DFIs. Between January 2017 and December 2022, a series of patients with DFIs received treatment with NPWTi-d, using either PHMB-B or normal saline as the instillation solution. Data collected retrospectively included demographic information, baseline wound characteristics, and treatment outcomes. The study included 61 patients in the PHMB-B group and 73 patients in the normal saline group, all diagnosed with DFIs. In comparison to patients treated with normal saline, patients with PHMB-B exhibited no significant differences in terms of wound bed preparation time (P = 0.5034), length of hospital stay (P = 0.6783), NPWTi-d application times (P = 0.1458), duration of systematic antimicrobial administration (P = 0.3567), or overall cost of hospitalization (P = 0.6713). The findings of the study suggest that the use of either PHMB-B or normal saline as an instillation solution in NPWTi-d for DFIs shows promise and effectiveness, yet no clinical distinction was observed between the two solutions.

Is Shock Wave Application Effective on Various Chronic Wounds in the Geriatric Population? Preliminary Clinical Study.

Purpose: Extracorporeal shock wave therapy (ESWT) is a beneficial adjunct modality for chronic wounds. Limited research has been conducted on pressure ulcers (PUs), while the majority of studies have focused on diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs). This study aimed to evaluate the short-term effects of radial ESWT in older adults with chronic wounds. Patients and Methods: This study involved a total of 31 wounds: PUs (n=22), VLUs (n=7), and DFUs (n=2). A single radial ESWT was performed with 300 + 100 shocks per cm2, pressure of 2.5 bar, energy of 0.15 mJ/mm2, and frequency of 5 Hz. Assessments using digital planimetry and clinical methods, utilizing the Wound Bed Score (WBS) and the Bates-Jansen Wound Assessment Tool (BWAT) were performed before the radial ESWT application (M0) and one week after (M1). Results: A significant wound decrease in planimetry was noted (pre-ESWT vs post-ESWT), with wound area from 9.4 cm2 to 6.2 cm2, length from 6.4 cm to 3.9 cm, and width from 2.8 cm to 2.1 cm (p<0.001). Additionally, a substantial clinical improvement was noted in both the WBS with a 31.25% increase and the BWAT with a 20.00% increase (p<0.001). It was also found a significant correlation between the planimetric and clinical outcomes for both tools: WBS (r=-0.446, p=0.012) and BWAT (r=0.327, p=0.073). Conclusion: The ESWT application yields substantial immediate clinical effects that support the healing of chronic wounds in older adults. Even a single ESWT session can prove to be clinically effective and beneficial in the management of chronic wounds.

The role of machine learning in advancing diabetic foot: a review.

Background: Diabetic foot complications impose a significant strain on healthcare systems worldwide, acting as a principal cause of morbidity and mortality in individuals with diabetes mellitus. While traditional methods in diagnosing and treating these conditions have faced limitations, the emergence of Machine Learning (ML) technologies heralds a new era, offering the promise of revolutionizing diabetic foot care through enhanced precision and tailored treatment strategies. Objective: This review aims to explore the transformative impact of ML on managing diabetic foot complications, highlighting its potential to advance diagnostic accuracy and therapeutic approaches by leveraging developments in medical imaging, biomarker detection, and clinical biomechanics. Methods: A meticulous literature search was executed across PubMed, Scopus, and Google Scholar databases to identify pertinent articles published up to March 2024. The search strategy was carefully crafted, employing a combination of keywords such as "Machine Learning," "Diabetic Foot," "Diabetic Foot Ulcers," "Diabetic Foot Care," "Artificial Intelligence," and "Predictive Modeling." This review offers an in-depth analysis of the foundational principles and algorithms that constitute ML, placing a special emphasis on their relevance to the medical sciences, particularly within the specialized domain of diabetic foot pathology. Through the incorporation of illustrative case studies and schematic diagrams, the review endeavors to elucidate the intricate computational methodologies involved. Results: ML has proven to be invaluable in deriving critical insights from complex datasets, enhancing both the diagnostic precision and therapeutic planning for diabetic foot management. This review highlights the efficacy of ML in clinical decision-making, underscored by comparative analyses of ML algorithms in prognostic assessments and diagnostic applications within diabetic foot care. Conclusion: The review culminates in a prospective assessment of the trajectory of ML applications in the realm of diabetic foot care. We believe that despite challenges such as computational limitations and ethical considerations, ML remains at the forefront of revolutionizing treatment paradigms for the management of diabetic foot complications that are globally applicable and precision-oriented. This technological evolution heralds unprecedented possibilities for treatment and opportunities for enhancing patient care.

Efficacy and safety of ultrasound-assisted wound debridement in the treatment of diabetic foot ulcers: a systematic review and meta-analysis of 11 randomized controlled trials.

Objective: Research data suggests that ultrasound-assisted wound debridement (UAWD) can effectively promote the healing of diabetic foot ulcers (DFU). However, existing research is not consistent with this viewpoint. Therefore, we conducted this study to investigate the effect of UAWD on the healing of diabetic foot ulcers. Methods: From the establishment of the database to January 2024, we searched 8 databases to study the effectiveness and safety of UAWD in the treatment of DFU. Two authors independently screened the qualifications of the articles, while two authors extracted relevant data. Statistical analysis was conducted using Review Manager 5.4 and STATA 18.0 software. Results: A total of 11 randomized controlled studies were included, with 6 countries and 696 participants participating. Our findings showed that UAWD was associated with a significant benefit in healing rate (OR = 2.60, 95% CI: [1.67, 4.03], P < 0.0001, I2 = 25%), wound healing time (MD = -11.94, 95% CI: [-23.65, -0.23], P = 0.05, I2 = 99%), percentage reduction in wound size (MD = 14.2, 95% CI: [10.8, 17.6], P = 0.47, I2 = 32%), effectiveness of treatment (OR = 10.3, 95% CI: [4.68, 22.66], P < 0.00001, I2 = 0%). Moreover, UAWD did not cause any significant adverse reactions. However, there was no obvious difference in wound blood perfusion (MD = 0.25, 95% CI: [-0.01, 0.52], P = 0.06, I2 = 90%), transcutaneous oxygen partial pressure (MD = 14.34, 95% CI: [-10.03, 38.71], P = 0.25, I2 = 98%). Conclusion: UAWD can significantly improve wound healing rate, shorten wound healing time, accelerate wound area reduction, and improve clinical treatment effectiveness without significant adverse reactions. Although there is no significant difference in transcutaneous oxygen pressure and wound blood flow perfusion between UAWD and SWC. So we look forward to more scientifically blinded, placebo-controlled, high-quality studies in the future, to enable researchers to obtain more complete and accurate analytical data, in order to improve the scientific and credibility of the evidence.

Treating chronic wounds in an acute care setting: the forgotten diagnosis.

BACKGROUND: Chronic wounds include lower extremity ulcers, diabetic foot ulcers, and pressure injuries, and can take months or years to heal. Wounds place a high burden on outpatient and inpatient care settings. This burden is expected to increase markedly in the United States as the population ages and with increased rates of diabetes, obesity, and COVID-19. PURPOSE: To articulate the effect of chronic, hard-to-heal wounds on acute care facilities, and how a few days of inpatient care can have a significant effect on the healing trajectory. METHODS: An expert panel of 7 members, all with extensive knowledge and experience in the assessment and treatment of chronic wounds in an acute care setting, was convened in March 2022. The panel discussed the role of hospitals as part of the longer-term healing pathway of chronic wounds. RESULTS: Chronic wounds have a significant effect on hospitals that includes unseen costs, bed occupancy, demands on bedside nurses, and wound complications that lead to extended stays or readmissions. A successful inpatient wound program offers appropriate identification of previously undiagnosed wounds, elevation of bedside care through simplified protocols, quickly and easily understood education and easy dressing selection, and comprehensive discharge planning with a multidisciplinary team for continuity of care and reduced risk of readmission. CONCLUSION: Hospitals can play a key role in the management of chronic wounds, thus reducing the effect on each facility and the wider care network.

Association of Preulcerative Foot Care and Outcomes of Diabetic Foot Ulceration.

BACKGROUND: The purpose of this study was to determine the association of preulcerative foot care and outcomes of diabetic foot ulcerations (DFUs). METHODS: This retrospective cohort study using the Mariner all-payers claims data set included participants with a new DFU from 2010 to 2019. Patients were stratified into two cohorts (foot care and control) based on whether they had received any outpatient foot care within 12 months before DFU. Adjusted comparison was performed by propensity matching for age, sex, and the Charlson Comorbidity Index (1:2 ratio). Kaplan-Meier estimates and logistic regression examined the association between foot care and outcomes of DFUs. RESULTS: Of the 307,131 patients in the study cohort, 4.7% (n = 14,477) received outpatient preulcerative foot care within the 12-month period before DFU. The rate of major amputation was 1.8% (foot care, 1.2%), and 9.0% of patients had hospitalizations for foot infection within 12 months after DFU (foot care, 7.8%). In the study cohort, patients who received pre-DFU foot care had greater major amputation-free survival (P < .001) on Kaplan-Meier estimate. In both the study and matched cohorts, multivariable analysis demonstrated that foot care was associated with lower odds of major amputation for both study (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.48-0.66) and matched (OR, 0.61; 95% CI, 0.51-0.72) cohorts, and lower odds of hospitalizations for a foot infection in both study (OR, 0.91; 95% CI, 0.86-0.96) and matched (OR, 0.88, 95% CI, 0.82-0.94) cohorts. CONCLUSIONS: Among patients with a new DFU, those who received outpatient preulcerative foot care within 12 months of diagnosis had lower risks of major amputation and hospitalizations for foot infection.

Foot self-care behaviour in primary care patients with diabetic foot ulcers: Structural equation modelling of psychological predictors.

Diabetic foot ulcers (DFUs) are one of the most prevalent and costly diabetes complications, associated with diminished quality of life and poor prognosis. Management of DFUs relies heavily on patients' foot self-care behaviour. This study aims to explore psychological determinants of this important behaviour among primary care patients. A total of 186 patients with active DFUs self-reported their illness perception, diabetes distress, self-efficacy, and foot self-care behaviour. Structural equation modelling was performed to examine interrelationships among measured variables. The final model demonstrated satisfactory fit, CFI = 0.933, TLI = 0.913, RMSEA = 0.050, SRMR = 0.073, χ2(95) = 132.256 (p = 0.004), and explained 51.1% of the variance of foot self-care. Illness threat perceptions (i.e., consequence, timeline, identity, concern, and emotion) had a direct positive effect on foot self-care behaviours, but also indirectly decreased foot self-care through increasing diabetes distress. Control perceptions (i.e., personal control, treatment control, and coherence) were not directly associated with foot self-care behaviours, but indirectly improved foot self-care by reducing diabetes distress and increasing foot care confidence. These findings suggest illness perceptions, diabetes distress, and self-care confidence as modifiable predictors to be targeted in self-management interventions for patients with DFUs.

Limb salvage and systemic management of gouty tophi: Case series.

INTRODUCTION: Gout is a chronic disease characterized by deposition of monosodium urate crystals. Tophi develop in some individuals with untreated or uncontrolled gout, which leads to ulcerations, cosmetic problems, mechanical obstruction of joint movement, joint damage and musculoskeletal disability. Currently, the treatment of gouty tophi is controversial and challenging. Both surgical and internal medical treatments have limitations and require further exploration in clinical practice. PATIENT CONCERNS: In Case 1, we treated a patient with severe infection of diabetic foot ulcers with concomitant multiple gouty tophi in the same limb. A systematic management strategy was formulated to close the wound and save the limb. The ulcers healed successfully after half a year. In Case 2, a giant gouty tophi located in the first metatarsophalangeal joint of the left foot was removed by surgical treatment and vancomycin-loaded bone cement implantation. In Case 3, we present a case of gouty tophi that was resolved by standardized systemic medical management. DIAGNOSIS: Three patients were all diagnosed with gout accompanied by gouty deposition, although there were other different comorbidities. INTERVENTIONS: In case 1, we used debridement to gradually remove gouty tophi. In case 2, the giant gouty tophi was removed by surgical operation. In case 3, the gouty tophi disappeared after standardized treatment with medicine, diet and lifestyle management. OUTCOMES: Three patients underwent different treatment therapies to remove gouty tophi based on their specific conditions. LESSONS: We explored effective interventions for tophi in gout by surgical or other interventions in combination with pharmacotherapy.

'Nutrition has everything to do with wound healing'-health professionals' perceptions of assessment and management of nutrition in individuals with diabetes-related foot ulceration.

Determine how healthcare professionals perceive their role in nutrition assessment and management, and explore barriers and enablers to assessment and management of nutrition in individuals with DFU. Mixed methods including a cross-sectional online survey derived from current international guidelines and theoretical domains framework, and semi-structured interviews with conventional content analysis was performed. One hundred and ninety-one participants completed the survey, with 19 participating in interviews. Many health professionals are not confident in their ability in this area of practice, are uncertain their nutrition advice or management will be effective in assisting wound healing outcomes and are uncertain their intervention would result in adequate behaviour change by the individual with DFU. Major barriers to implementation of nutrition assessment and management were: inadequate time, lack of knowledge and lack of clinical guidance and enablers were as follows: professional development, a standardised clinical pathway and screening tool and a resource addressing wound healing and diabetes management. Nutrition assessment and management in individuals with DFU is not consistently applied. Whilst health professionals believed nutrition was important for wound healing, they lacked confidence in implementing into their practice. Further dissemination of existing guidance and implementation of education programs and resources would help overcome cited barriers.

Impact of foot ulcer-related factors on quality of life in patients with diabetes: Prospective observational study.

Quality of life (QOL) may be impacted by foot ulcer-related factors, with prevention of diabetes-related foot ulcers or more effective early healing helping to improve overall patient QOL. This study, which examined the relationship between foot ulcer-related factors and QOL in patients with diabetes, was conducted as a secondary analysis of a prospective observational study entitled: "Factors associated with the discontinuation of wound care specialist clinic visits in patients with diabetic foot ulcers". We investigated EQ-5D-5L, patient characteristics and foot ulcer-related factors of 73 patients with diabetes-related foot ulcers who visited one wound clinic in Indonesia between August 2020 and February 2021. Results showed that the mean health utility was 0.294 ± 0.371. Factors selected for the multiple regression analysis included inflammation/infection of DMIST, first-ever foot ulcer, and size of DMIST. First-ever foot ulcer (ß = 0.309, p = 0.003) and size of DMIST (ß = -0.316, p = 0.015) were significantly associated with the health utility (p < 0.001). Significant improvement in the health utility of 15 patients was observed when the ulcer healed (Wilcoxon signed-rank sum test, p = 0.001). In conclusion, not only ulcer severity but also the first-ever foot ulcer itself affected the QOL in patients with diabetes. These results suggest there will be a greater impact on the QOL of patients who develop diabetes-related foot ulcers for the first time, along with the importance of prevention and early healing, through early infection control and wound size reduction.

Treatment of Diabetic Foot Ulcers Based on an Interdisciplinary Team Approach: Exploratory Cross-Sectional Study of Patients' Views on Quality of Care.

PURPOSE: The purpose of this study was to evaluate patients' perception and quality of diabetic foot ulcer (DFU) care delivered by an interdisciplinary team approach (ITA). DESIGN: Exploratory cross-sectional study. SUBJECTS AND SETTING: Twenty patients with a healed plantar DFU were recruited from an interdisciplinary Wound Care clinic of a Canadian University affiliated hospital. Their mean age was 64 years (75% were males [n = 15]), 18 (90%) were living with type 2 diabetes, and 45% (n = 9) had osteomyelitis in the previous year of their enrollment in the study. METHODS: The validated short form of the Quality From the Patient's Perspective questionnaire was used to evaluate quality of care dimensions (medical-technical competence of the caregivers; physical-technical conditions of the care organization; degree of identity-orientation in the attitudes and actions of the caregivers; and sociocultural atmosphere of the care organization). RESULTS: Respondents reported experiencing a high level of quality care with an ITA. All indicators of patient-perceived reality of care delivered were superior or equal related to their subjective importance in all dimensions of quality care (with scores ranging from 3.85 to 4.00 on a 4-Point Likert scale). Patients' satisfaction regarding the ITA was high. CONCLUSIONS: Study findings suggest that an ITA model provided high quality of care for treating DFUs for all quality dimensions judged important for patients.

Retention of Improved Plantar Sensation in Patients with Type II Diabetes Mellitus and Sensory Peripheral Neuropathy after One Month of Vibrating Insole Therapy: A Pilot Study.

Sensory peripheral neuropathy is a common complication of diabetes mellitus and the biggest risk factor for diabetic foot ulcers. There is currently no available treatment that can reverse sensory loss in the diabetic population. The application of mechanical noise has been shown to improve vibration perception threshold or plantar sensation (through stochastic resonance) in the short term, but the therapeutic use, and longer-term effects have not been explored. In this study, vibrating insoles were therapeutically used by 22 participants, for 30 min per day, on a daily basis, for a month by persons with diabetic sensory peripheral neuropathy. The therapeutic application of vibrating insoles in this cohort significantly improved VPT by an average of 8.5 V (p = 0.001) post-intervention and 8.2 V (p < 0.001) post-washout. This statistically and clinically relevant improvement can play a role in protection against diabetic foot ulcers and the delay of subsequent lower-extremity amputation.
