Early identification of delayed wound healing in complex diabetic foot ulcers treated with a dermal regeneration template: a novel clinical target and its risk factors. Int J Surg 2024; 110:943-955. [PMID: 38085826 PMCID: PMC10871583 DOI: 10.1097/js9.0000000000000898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 11/02/2023] [Indexed: 02/17/2024]
Abstract
BACKGROUND The dermal regeneration template (DRT), a tissue-engineered skin substitute composing a permanent dermal matrix and an upper temporary silicone layer that serves as the epidermis, has demonstrated efficacy in treating uncomplicated diabetic foot ulcers (DFUs). Our institution has obtained good outcomes with DRT in patients with more complicated DFUs. Because of its chronicity, the authors are working to identify a clinical target that anticipates delayed healing early in the treatment in addition to determining the risk factors linked to this endpoint to increase prevention. MATERIALS AND METHODS This retrospective single-center study analyzed patients with DFUs who underwent wound reconstruction using DRT between 2016 and 2021. The patients were categorized into poor or good graft-take groups based on their DRT status on the 21st day after the application. Their relationship with complete healing (CH) rate at day 180 was analyzed. Variables were collected for risk factors for poor graft take at day 21. Independent risk factors were identified after multivariable analysis. The causes of poor graft take were also reported. RESULTS This study examined 80 patients (38 and 42 patients in the poor and good graft-take groups, respectively). On day 180, the CH rate was 86.3% overall, but the poor graft-take group had a significantly lower CH rate (76.3 vs. 95.2%, P =0.021) than the good graft-take group. Our analysis identified four independent risk factors: transcutaneous oxygen pressure less than 30 mmHg (odds ratio, 154.14), off-loading device usage (0.03), diabetic neuropathy (6.51), and toe wound (0.20). The most frequent cause of poor graft take was infection (44.7%), followed by vascular compromise (21.1%) and hematoma (15.8%). CONCLUSION Our study introduces the novel concept of poor graft take at day 21 associated with delayed wound healing. Four independent risk factors were identified, which allows physicians to arrange interventions to mitigate their effects or select patients more precisely. DRT represents a viable alternative to address DFUs, even in complicated wounds. A subsequent split-thickness skin graft is not always necessary to achieve CH.

Abstract
This manuscript describes the implementation and initial evaluation of a novel Canadian acute care pathway for people with a diabetic foot ulcer (DFU). A multidisciplinary team developed and implemented an acute care pathway for patients with a DFU who presented to the emergency department (ED) and required hospitalisation at a tertiary care hospital in Canada. Processes of care, length of stay (LOS), and hospitalisation costs were considered through retrospective cohort study of all DFU hospitalizations from pathway launch in December 2018 to December 2020. There were 82 DFU-related hospital admissions through the ED of which 55 required invasive intervention: 28 (34.1%) minor amputations, 16 (19.5%) abscess drainage and debridement, 6 (7.3%) lower extremity revascularisations, 5 (6.1%) major amputations. Mean hospital LOS was 8.8 ± 4.9 days. Mean hospitalisation cost was $20 569 (±14 143): $25 901 (±15 965) when surgical intervention was required and $9279 (±7106) when it was not. LOS and hospitalisation costs compared favourably to historical data. An acute care DFU pathway can support the efficient evaluation and management of patients hospitalised with a DFU. A dedicated multidisciplinary DFU care team is a valuable resource for hospitals in Canada.

Abstract
PURPOSE The purpose of this study was to explore patients' perception of reasons contributing to delay in seeking help and referral to a wound care specialist at the onset of a diabetic foot ulcer (DFU). DESIGN Constructivist grounded theory study. SUBJECTS AND SETTING The sample comprised 30 individuals with active DFU attending a wound care clinic in southeastern Ontario, Canada. METHODS Participants were selected through purposive and theoretical sampling. Semistructured interviews were conducted with participants until no new properties of the patterns emerged. All interviews were transcribed, coded, and analyzed using methods informed by constructivist grounded theory. RESULTS The reasons contributing to delay to seek help and referral to a wound care specialist were (1) limited knowledge about foot care, (2) unaware of diabetic foot problems, (3) underestimation of ulcer presentation, (4) I thought I could fix it myself, (5) inaccurate diagnosis, and (6) trial and error approach by a nonspecialized wound care provider. CONCLUSIONS Study findings suggest that patients and primary healthcare providers need additional education regarding the management of diabetic foot disease and DFU.

Abstract
OBJECTIVES The purpose of this study was to determine the feasibility and safety of a novel decellularized dermal matrix (DDM) for the treatment of chronic diabetic foot ulcers (DFUs). METHODS An interventional, single-arm, prospective study of DDM for DFU treatment was conducted in 2 Canadian centres from July 1, 2016 to May 30, 2017. Individuals ≥18 years of age, with an active DFU of ≥2 weeks and ulcer area ≥1 cm2 before debridement and who consented to participate, were enrolled in this clinical trial. RESULTS A total of 11 patients were enrolled, with 9 patients (82%) having achieved 100% closure between 2 and 8 weeks. The mean and median times to wound closure for these patients were 3.3 and 2.5 weeks, respectively. The mean and median reductions in wound area at 4 weeks posttreatment were 87% and 100%, respectively. The proportion of patients having achieved complete healing at 12 weeks was 82%. All patients received only 1 DDM application to achieve these results. There were no adverse events related to use of the product. No cases of recurrence during a 1-year follow up after completion of the study were reported for patients who achieved wound closure. CONCLUSIONS These findings provide evidence that this DDM may be safe and effective for the treatment of chronic, hard-to-heal neuropathic DFUs. Specifically, DDM demonstrated the potential to accelerate healing of DFUs when compared with reported times of 8 to 12 weeks required to achieve closure using the current standard of care.

Abstract
BACKGROUND Early detection of hard-to-heal diabetic foot ulcers (DFUs) is vital to prevent a poor prognosis. The purpose of this work was to employ clinical characteristics to create an optimal predictive model of hard-to-heal DFUs (failing to decrease by >50% at 4 weeks) based on machine learning algorithms. METHODS A total of 362 DFU patients hospitalized in two tertiary hospitals in eastern China were enrolled in this study. The training dataset and validation dataset were split at a ratio of 7:3. Univariate logistic analysis and clinical experience were utilized to screen clinical characteristics as predictive features. The following six machine learning algorithms were used to build prediction models for differentiating hard-to-heal DFUs: support vector machine, the naïve Bayesian (NB) model, k-nearest neighbor, general linear regression, adaptive boosting, and random forest. Five cross-validations were employed to realize the model's parameters. Accuracy, precision, recall, F1-scores, and AUCs were utilized to compare and evaluate the models' efficacy. On the basis of the best model identified, the significance of each characteristic was evaluated, and then an online calculator was developed. RESULTS Independent predictors for model establishment included sex, insulin use, random blood glucose, wound area, diabetic retinopathy, peripheral arterial disease, smoking history, serum albumin, serum creatinine, and C-reactive protein. After evaluation, the NB model was identified as the most generalizable model, with an AUC of 0.864, a recall of 0.907, and an F1-score of 0.744. Random blood glucose, C-reactive protein, and wound area were determined to be the three most important influencing factors. A corresponding online calculator was created (https://predicthardtoheal.azurewebsites.net/). CONCLUSION Based on clinical characteristics, machine learning algorithms can achieve acceptable predictions of hard-to-heal DFUs, with the NB model performing the best. Our online calculator can assist doctors in identifying the possibility of hard-to-heal DFUs at the time of admission to reduce the likelihood of a dismal prognosis.

Abstract
Diabetes mellitus is considered a silent disease with possible late chronic complications such as diabetic foot ulcer. This condition is managed by surgical debridement. To improve surgical outcome, some surgeons use proteolytic agents after surgery. Kiwifruit contains a type of proteolytic enzyme called actinidin that may play a role in the treatment of such complication. In the current study, we evaluate the role of kiwifruit extract in the treatment of diabetic foot ulcer. Eighteen diabetic foot ulcer patients were included in a randomized, double-blind clinical trial. The patients were divided randomly to control and experimental groups. Patients in the control group underwent daily wound dressing using base ointment (Eucerin). In the experimental group, we added kiwifruit extract to the standard wound dressing. Clinical data including general appearance of wound (according to recorded photographs before and after medical intervention) were analyzed using SPSS version 22. The mean wound area of the experimental group was significantly less than in the control group (P = .005) after 4 weeks of treatment. Comparison of the average of size difference, before and after the treatment in the experimental group and the control group, shows that kiwifruit can have a good impact on wound healing (P = .0001). In patients with diabetic foot ulcer, wound dressing using kiwifruit extract may help reduce time of treatment and may replace surgical debridement for some selected cases.

Abstract
The aim of this study was to determine the wound healing outcomes of patients with a plantar diabetic foot ulcer (DFU) treated with an interdisciplinary team approach, and to identify associated variables. A retrospective observational cohort study of 140 adult patients, with a plantar DFU, treated between 2012 and 2018 at a wound care clinic of a University affiliated hospital was conducted. Predictive and explicative analyses were conducted with logistic multivariate methods and with a Receiver Operating Characteristics curve. The best predictor of wound healing at 3 months was a 41.8% wound size reduction at 4 weeks (AUC: 0.86; sensitivity: 83.1%; specificity: 67.2%, positive predictive value: 72.8%; negative predictive value: 78.9%; positive and negative likelihood ratios: 2.53 and 0.25, respectively). Main baseline variables independently associated with this predictor were: a monophasic Doppler waveform (OR 7.52, 95% CI [2.64–21.39]), cigarette smoking (OR 4.7, 95% CI [1.44–15.29]), and male gender (OR 3.58, 95% CI [1.30–9.87]). The health care provider should be cautious and intensify its management of DFUs particularly with patients of male gender; smoking, having a monophasic waveform with a hand‐held Doppler, and not achieving a minimal 41.8% wound area reduction at 4 weeks of treatment.

Abstract
Background One Australian loses a limb every 3 h as a result of infected diabetic foot ulcers (DFU). This common condition accounts for substantial morbidity and mortality for affected individuals and heavy economic costs for the health sector and the community. There is an urgent need to test interventions that improve wound healing time, prevent amputations and recurrent ulceration in patients presenting with DFU whilst improving quality of life and reducing health care costs. Methods One hundred and fifty eligible participants will be randomised to receive an autologous skin cell suspension, also termed 'spray-on' skin (ReCell®) or standard care interventions for their DFU. The primary outcome is complete wound healing at 6 months, but participants will be followed up for a total of 12 months to enable secondary outcomes including total overall costs, ulcer free days at 12 months and quality of life to be assessed. Discussion Outpatient costs for dressings, home nursing visits and outpatient appointments are key cost drivers for DFU. If spray-on skin is effective, large cost savings to WA Health will be realised immediately through a shortened time to healing, and through a higher proportion of patients achieving complete healing. Shortened healing times may enable participants to return to work earlier. Any economic benefits are likely to be amplified across Australia and other similar demographic settings where aging populations with increased diabetes rates are considered major future challenges.

Abstract
The role of smoking for wound healing in patients with diabetic foot has been unclear. This meta-analysis examined the relationship between cigarette smoking and diabetic foot wound healing. Observational studies for the association between smoking and diabetic foot wound healing of patients were systematically searched through PubMed and Wanfang Data, published up to June 2018. Healing rates of wounds were recognized as outcomes. Meta-analysis models were chosen by heterogeneity. A total of 3388 eligible studies were identified, of which 18 met all our inclusion criteria. In the smoking group, healing rate had an average of 62.1%, ranging from 20.0% to 89.6%; in the nonsmoking group, healing rate had an average of 71.5%, ranging from 40.2% to 93.8%. A significant association was found between smoking and the healing of diabetic foot wounds ( z = 3.08; P = .002), with an odds ratio (OR) of 0.70 (95% CI = 0.56-0.88), based on a random-effects model. Meta-regression analyses indicated that the heterogeneity did not come from publication year ( t = -0.50, P = .622) or overall healing rate ( t = 0.16, P = .872). The leave-one-out sensitivity analysis was robust; sensitivity analysis for pooled estimate of adjusted ORs had an OR of 0.20 (95% CI = 0.07-0.56; z = 3.08; P = .002). Subgroup analysis had an OR of 0.62 (95% CI = 0.41-0.95; z = 2.21; P = .027) in retrospective cohort studies and had an OR of 0.75 (95% CI = 0.57-0.99; z = 2.02; P = .043) in prospective cohort studies. Our meta-analysis indicated that smoking had an overall negative effect on the wound healing of diabetic foot individuals. This study provides evidence for the harm of smoking to diabetic foot and may help reduce the medical and economic burden on poor healing of diabetic foot.
