Comparison of the effect of combination therapies in the treatment of large varicose ulcers: A real-world cohort study.

OBJECTIVES: The primary treatment for varicose ulcers is to address the underlying cause of venous hypertension, additionally, split-thickness skin transplantation (ST) is an effective option for large ulcers. The aim of this study was to compare the efficacy of venous surgery with or without split-thickness ST in the management of varicose ulcers (diameter ≥6 cm). METHODS: Patients with varicose ulcers between 2013 and 2023 were included in the real-world retrospective cohort study. The endovenous microwave ablation/endovenous laser ablation-high ligation-foam sclerotherapy-compression therapy + ST group (EMA/EVLA-CT-HL-FS + ST) consisted of 32 patients, while the EMA/EVLA-CT-HL-FS group consisted of 48 patients. RESULTS: A difference in ulcer healing time was found between the two groups (the hazard ratio [HR] was 4.4, 95% CI [2.3-8.2], P < 0.0001). However, the healing rate did not differ between the two groups at 6 and 12 months postoperatively. CONCLUSION: ST has been shown to expedite ulcer healing and ameliorate the symptoms of VVs in the early stages of treatment, while its intermediate to long-term efficacy for ulcer healing and overall patient quality of life may be limited.

Impact of primary dressings on healing of venous leg ulcers: a French cohort study from the healthcare insurance database.

OBJECTIVE: Multicomponent bandages (MCBs) are recommended by the French Authority for Health (Haute Autorité de Santé) as first-line treatment for venous leg ulcers (VLUs). A first analysis of the data collected from the French administrative healthcare database (Système National des Données de Santé (SNDS)) on 25,255 patients with a VLU supported superiority of MCBs versus short stretch bandages when considering the healing outcomes and costs associated with closure of these wounds. The aim of this study was to assess how beneficial the primary dressing (technology lipido-colloid nano-oligosaccharide factor (TLC NOSF) or control dressing group (CDG)) could be, when used in combination with MCBs in the treatment of VLUs. METHOD: Data from the SNDS were collected for patients meeting the following inclusion criteria: treatment for a VLU with MCBs and with the same dressing type (TLC-NOSF or CDG) during the whole treatment period. Healing outcomes were documented on the global cohorts and propensity score-matched cohorts. The mean healthcare cost and the ecological impact were calculated for those patients healed within the study period. RESULTS: In total, 12,507 patients met the criteria for treatment with both MCBs and TLC-NOSF dressings (n=1134) versus MCBs and CDG (n=11,373); with 1134 and 2268 patients per group following propensity score matching. Healing outcomes were favourable for the TLC-NOSF group in the global cohort and were enhanced in the propensity score-matched cohorts. At every point of the analysis, the adjusted healing rates were significantly higher in the TLC-NOSF group than in the CDG group (p<0.001). In the propensity score-matched cohorts (n=3402), the healing rate at three months was 52% in the TLC-NOSF group versus 37% in the CDG group (p<0.001). The median healing time was 87 days versus 125.5 days in the TLC-NOSF and CDG groups, respectively (p<0.0001). TLC-NOSF dressings significantly reduced the average treatment cost per healed ulcer (€2099) by 23.7% compared with dressings without TLC-NOSF (€2751) (p<0.001), as well as the resources used. CONCLUSION: This SNDS analysis confirms, in the largest real-life study performed in VLU management, the superiority of the TLC-NOSF dressings versus those not impregnated with the NOSF compound. Better clinical outcomes associated with cost savings and a positive ecological impact support the combination of MCBs and TLC-NOSF dressings and should be considered as an optimal standard of care for the global management of VLUs. These outcomes reinforce the current positions of the international guidelines on the use of NOSF impregnated dressings (UrgoStart range; Laboratoires Urgo, France) in this pathology.

Impact on healing of double-layered compression stocking in the treatment of severe venous leg ulcers: A prospective, multicenter, controlled trial.

Venous leg ulcer refers to chronic wounds, generally difficult to heal and often prone to recurrence. The objective of this research was to assess a double layered compression stocking VenoTrain® ulcertec on a population with mostly severe pathologies. This prospective, multicenter, interventional type II study was conducted between September 2018 and January 2022. Out of 124 patients enrolled, 97.6% had a history of previous leg ulceration, 72.6% were already being followed for leg ulcerations, 30.9% were severely overweight and 24.2% diabetic. Overall, a majority of target ulcers were present for 6months or more, and the ulcer surface area was larger than 8cm2 in nearly one in every five cases. The primary endpoint was the rate of closed ulcer after a maximum follow-up of 20weeks. While most of the treated venous leg ulcerations may be regarded as hard-to-heal wounds, closure rate at 20weeks ranged between 50.0% (two severity criteria) and 69.0% (no severity criteria) according to baseline wound severity criteria. Besides, VenoTrain® ulcertec device was particularly well accepted and tolerated by patients. In 93.2% of visits, patients stated using it every day. When managing venous ulcerations not requiring strongly thick absorbent dressings, VenoTrain® ulcertec device represents an efficient and more suitable alternative to venous compression bandaging.

The use of a multimodal wound matrix to treat a variety of hard-to-heal wounds: a case series surveillance.

OBJECTIVE: This case series examines the use of a multimodal wound matrix (MWM) trialled in a selection of clinical practice settings and on a variety of hard-to-heal wounds. The objective was to evaluate the effects of MWM and its performance in managing such wounds, regardless of clinical setting and ulcer type. METHOD: Treatment of the MWM was conducted by independent wound care practitioners on wounds that were of >4 weeks duration. Treatment was once a week. Assessment was taken after four weeks and at week 12 of the study to assess percentage area reduction (PAR) compared to baseline measurements taken at the first treatment visit. Complete (100%) re-epithelialisation was also recorded. RESULTS: A total of 63 wounds were treated with MWM, and ulcer types were grouped as: diabetic foot ulcers (n=21); venous leg ulcers (n=18); pressure injuries (n=10); and others (n=14). Of the wounds, 78% had 100% re-epithelialisation, with an average PAR of 57% at four weeks and 86% at 12 weeks. The average time to resolution for those wounds that closed was 7.9 weeks. CONCLUSION: Results from this series of independent case studies support the application of MWM to potentially benefit healing in hard-to-heal wounds of different aetiologies of any duration and in a variety of clinical settings.

Evaluating the number of cellular and/or tissue-based product applications required to treat diabetic foot ulcers and venous leg ulcers in non-hospital outpatient department settings.

BACKGROUND: There is substantial literature supporting the use of cellular and/or tissue-based product (CTP) in managing Wagner grade 1 and 2 diabetic foot ulcers (DFUs) and, to a lesser extent, venous leg ulcers (VLUs). Several studies advocate CTP therapy as an effective method for promoting healing in chronic DFUs and VLUs. OBJECTIVE: To evaluate how the number of CTP applications affect healing and wound area reduction (WAR) rates of DFUs and VLUs. METHODS: A multicenter private wound care practice, electronic health record, and database were used to analyze Medicare patients receiving CTPs between January 1, 2018, and December 31, 2023. Wound treatments occurred in the nursing home, private office, and home settings, not in hospital outpatient department settings. This privately funded, non-vendor-sponsored, real-world retrospective analysis included wound closure and WAR rates after each CTP application. Analysis includes current (2024) aspects of proposed local coverage determination changes that limit the number of CTP applications to 4. A paired t test was used to compare mean wound area before CTP applications and after completing CTP applications over a 16-week period. Effect sizes were analyzed using Cohen d, and correlations between the number of CTP applications and WAR were determined using the Pearson correlation coefficient. RESULTS: A total of 257 wounds were reviewed for analysis, of which 123 were DFUs and 134 were VLUs. For both DFUs and VLUs, there was a significant difference in the average initial wound areas (cm2) compared with the average wound areas after the CTP application series (P < .001). CONCLUSION: This comprehensive retrospective real-world analysis of Medicare patients receiving CTP therapy in conjunction with standard of care treatment of DFUs and VLUs demonstrated significant reduction in the average wound area after completing a CTP application series. The results of this study could be used as a guide for the average number of CTP applications required for the effective treatment of DFUs and VLUs.

Continuous muscle pump activation by neuromuscular electrical stimulation of the common peroneal nerve in the treatment of patients with venous leg ulcers: A position paper.

The standard treatment for patients with confirmed Venous Leg Ulcers (VLUs) is compression therapy to improve the function of the calf muscle pump. There is a significant cohort of patients who are unable to tolerate optimal compression therapy or indeed any level of compression therapy. In addition, there is a cohort of patients who can tolerate compression whose ulcers show little or no evidence of healing. There is a need for ways to further improve calf muscle pump function and to improve venous ulcer healing in these patients. Published data were reviewed on the use of Muscle Pump Activation (MPA) using common peroneal nerve neuromuscular electrical stimulation (NMES) to improve calf muscle pump function. There is physiological evidence that MPA can improve calf muscle pump function and venous return in both control subjects and in patients with venous disease. The use of MPA has also been shown to improve venous flow volume and venous flow velocity on ultrasound scanning in patients with venous disease. MPA has been shown to improve microcirculation in the skin using Laser Doppler and laser Doppler Speckle Contrast Imaging, in both normal subjects as well as in patients with venous disease and VLU. A recent randomized controlled trial of MPA plus compression therapy compared with compression therapy alone, found significantly faster rates of healing with the use of MPA in addition to compression therapy. There are indications for the use of MPA as an adjunctive treatment to enhance calf muscle pump function in patients with VLU: who cannot tolerate compression therapy who can only tolerate suboptimal, low-level compression whose ulcer healing remains slow or stalled with optimal compression.

Effect of Unna's boot on venous ulcer healing: a systematic review and meta-analysis.

OBJECTIVE: To analyze the effect of Unna's Boot on the healing of venous ulcers compared to other therapies. METHODS: Systematic Review carried out in the databases Scopus, Embase, Cochrane Library, Web of Science, PubMed, Cumulative Index of Nursing and Allied Health Literature, Latin American and Caribbean Literature in Health Sciences, and grey literature. Population - adult patients with venous ulcers; Intervention- Unna's Boot (UB); Control - other compression therapies (CT); Outcome- healing; Designs- randomized clinical trial, cohort study, and case control, published from 2001 to 2024. The effect of the intervention, risk of bias, and quality of evidence were evaluated. Registered with PROSPERO (CRD42021290077). RESULTS: A total of 39 studies were included, with 5.151 patients. The majority (71.8%) were randomized controlled trials (RCT). UB was used as intervention/control in eight studies. When comparing CTs, only 1 study with UB showed a superior effect (p < .001) in healing, compared with high compression elastic bandage. In the quality of evidence analysis, 27 studies were assessed as having a high risk of bias. CONCLUSION: No superiority of UB was found in the healing of venous ulcers when compared to other CTs.

Effects of concurrent optical and magnetic stimulation in hard-to-heal wounds: a real-world evidence case series.

OBJECTIVE: This work explores concurrent optical and magnetic stimulation (COMS) effects on hard-to-heal wounds in real-world settings. METHOD: In this case series, participants received COMS 1-3 times per week for up to 12 weeks alongside standard wound care. RESULTS: A total of 27 patients (18 female and nine male) were included. Mean age was 72 years. Participants' wounds that were unresponsive to standard wound care included: venous leg ulcers (VLUs, n=13); mixed leg ulcers (MLUs, n=4); diabetic foot ulcers (DFUs, n=1); pressure ulcers (PUs, n=5); and traumatic wounds (TWs, n=4). On average, COMS was applied twice a week, resulting in an overall mean wound area reduction of 69%. In 24 participants, COMS was used primarily to achieve wound closure by the end of the 12-week period, of which: 12 were classified as complete wound closure (50%; VLUs=8, PUs=3 and TW=1); four as likely-to-heal (17%; VLUs=2 and MLUs=2); four as 'improved' (17%; MLU=1, DFU=1 and TWs=2); and four as 'non-responding' (17%; VLUs=3 and MLU=1). The best results were achieved in PUs and VLUs (respectively 100% and 62% categorised as completely healed). When used in participants where its purpose was other than that of achieving wound closure, COMS was successfully used to debride two PUs, and for wound bed preparation in one TW. CONCLUSION: In this case series, COMS showed positive effects and appeared to be beneficial in healing different types of hard-to-heal wounds in community health and homecare settings. Novel COMS therapy aspects emerged: (1) positive outcomes for PU and VLU treatment; (2) COMS as a potential debridement tool when sharp debridement is unfeasible; and (3) COMS as a promising method to prepare wound beds for subsequent skin grafting or skin replacement procedures.

The use of acellular products in venous leg ulcers: a narrative review.

BACKGROUND: Venous leg ulcers (VLUs) are the most common type of chronic wound in the lower extremity and are often associated with redness, swelling, and pain at the site of the wound. The primary focus of VLU treatment is the promotion of wound healing through compression therapy, wound debridement, and elevation of the affected limb. Acellular matrices have gained traction as a potential adjunct to wound healing in diabetic foot ulcers. However, the clinical effect of acellular products in the setting of VLUs has not been well reported. OBJECTIVE: To review the published evidence on the use of acellular products in the management of VLUs. METHODS: PubMed, Embase, Cochrane, and Google Scholar databases were initially searched on March 2, 2023, for literature on VLU and acellular dermal matrix. Later, the search was broadened to include any and all acellular matrices, and a secondary search of the same databases was conducted on February 20, 2024. Articles obtained through collateral methods were also included. RESULTS: A total of 27 articles were identified for review. All studies were human studies. Four articles had level I evidence and 7 articles had level II evidence, while the remaining articles had level III or IV evidence. Studies included both large and small wound sizes ranging from 0.5 cm² to 100 cm2. Product application occurred once to twice weekly for 4 weeks to up to 36 months. Overall, regardless of ulcer size, the majority of studies reported favorable wound healing outcomes with the use of a variety of acellular skin coverage products with few complications. Some studies also reported pain reduction with the use of acellular skin substitutes in a small cohort of patients. CONCLUSION: Acellular products appear to have the potential to support healing in VLUs. However, more large-scale randomized controlled trials that provide level I evidence are needed.

Characteristics of chronic ulcer patients by gender and ulcer aetiology from a multidisciplinary wound centre.

Chronic ulcer patients form a heterogenous group of patients with various medical backgrounds. Cost-effective targeted treatment necessitates more knowledge about specific features related to different subgroups of ulcer patients. Hence, this study aimed to characterize ulcer patients according to gender and ulcer aetiology. A total of 946 consecutively recorded chronic ulcer patients in the Tampere Wound Registry (TWR) were included and data were gathered from the TWR and patient medical records. Comparisons were made between males and females and patients with venous-, arterial or mixed-, diabetic foot-, pressure- and atypical ulcers. Male patients were found to have diabetes, hypercholesterolemia and obesity significantly more often than females (59.2% vs. 39.6%; p < 0.001, 46.5% vs. 33.3%; p = 0.001, 42.7% vs. 35.9%; p = 0.017 respectively), whereas autoimmune diseases were more common among females (30.6% vs. 15.6%; p < 0.001). Recurrence of ulcers was most common among patients with venous ulcers (p < 0.001) and multimorbidity among those with diabetic foot ulcers (p < 0.001). To conclude, males with chronic ulcers would benefit particularly from lifestyle advice, multidisciplinary treatment should be targeted specifically at those with diabetic and arterial or mixed ulcers and preventive measures at those with venous ulcers.

Treatment of bacterially contaminated lower extremity ulcers with a fatty acid-containing wound matrix: a case series.

OBJECTIVE: The aim was to evaluate the effectiveness of a marine omega fatty acid-containing multimodal wound matrix (MWM) in reducing bacterial contamination and supporting wound area reduction (WAR) in patients with hard-to-heal wounds of varying aetiologies. METHOD: A prospective, single-site, pilot case series of patients with hard-to-heal wounds. All wounds were considered non-healing prior to inclusion as they had failed to achieve at least 50% WAR after at least four weeks of standard of care (SoC) treatments. Patients were seen once weekly for wound assessments, matrix application and dressing changes. Baseline and weekly fluorescence images, standard wound images and wound measurements were obtained. RESULTS: A total of three patients, two with venous leg ulcers (VLUs) and one with a diabetic foot ulcer (DFU) were enrolled in this pilot study. The mean baseline wound age prior to study enrolment was 24 weeks, with a mean baseline wound size of 8.61cm2. The two VLUs went on to complete closure. The DFU displayed a total WAR of 53% by six weeks, when the patient was lost to follow-up due to a geographical relocation. The mean percentage area reduction of all wounds combined was 82% upon study completion. CONCLUSION: The use of MWM proved to be effective and safe in this patient cohort. The wounds included in this case series failed to enter a healing trajectory with SoC wound therapies. The MWM supported wound closure and reduced bacterial loads in this patient cohort.

The influence of socioeconomic factors on intervention and postoperative healing of venous ulcers: a prospective study.

OBJECTIVE: In previous studies, venous ulcers (VUs) have been found to occur more often in patients with lower socioeconomic status. The aim of this study was to explore if socioeconomic factors influence the delay of referral to a vascular service or the time to healing after superficial venous intervention. METHOD: In this prospective study, patients answered a questionnaire about the duration and recurrence of their VU, comorbidities, body mass index (BMI), smoking, alcohol, social and physical activities, ambulatory status, education, marital status, housing, perceived economic status and dependence on home care. Postoperative complications, VU healing and recurrence were noted one year after superficial venous intervention. RESULTS: A total of 63 patients were included in this study (30 females and 33 males), with a mean age of 71.2 years (range: 37-92 years). Duration of the present VU in patients was: <3 months in 48%; 3-6 months in 27%; 6-12 months in 11%; and >12 months in 14%. Risk factors for delayed referral were recurrent VU (odds ratio (OR): 4.92; p=0.021); walking impairment (OR: 5.43; p=0.009) and dependence on home care (OR: 4.89: p=0.039) in a univariable analysis. The latter was the only significant finding in a multivariable analysis with socioeconomic risk factor (OR: 4.89; p=0.035). In 85% of patients, their VU healed without recurrence during one year follow-up. Healing took longer if the patients: were of older age (p=0.033); had a normal BMI (independent samples t-test, p=0.028); had a recurrent VU (OR: 5.00; p=0.049); or walking impairment (Fishers exact test, OR: 9.14; p=0.008), but no significant socioeconomic risk factors were found. CONCLUSION: In this study, socioeconomic factors were not important risk factors for delayed referral of VU patients to a vascular service or prolonged healing time after superficial venous intervention.

Venous Leg Ulcers: The Need to Incorporate Age-Friendly 4M's in Management.

Venous leg ulcers develop due to a complex set of conditions routed in lower extremity edema and inflammation. Even though older adults are disproportionally affected by these wounds, the guidelines discuss best practices without keeping in mind the age-friendly 4M's-what Matters Most, Mobility, Medications, and Mentation/Mood. This article reviews the management and treatment of venous leg ulcers, but with a geriatric medicine focus. Compression therapy, mobility optimization, and social isolation reduction are highlighted for our older adult population.

Percutaneous transluminal angioplasty of femoropopliteal veins for treatment of post-thrombotic syndrome.

Background: Controversy persists concerning the endovascular treatment of the post-thrombotic syndrome (PTS), particularly if femoropopliteal veins are involved. Methods: We screened consecutive patients with PTS who underwent percutaneous transluminal angioplasty (PTA) of femoropopliteal veins using posterior tibial or popliteal vein access who had at least 3-month follow-up. Our assessment included the evaluation of primary and secondary patency of the treated segments by Doppler ultrasound (DUS) and clinical outcomes measured by the change in Villalta score as well as ulcer healing. Results: Among 29 patients, 8 (27.7%) were women and the mean (SD) age was 53.3 (13.6) years. Posterior tibial vein and popliteal access were used in 26 (89.7%) and 3 patients (10.3%), respectively. 13 (44.8%) patients had prior (n = 11, 37.9%) or concomitant (n = 9, 31.0%) endovascular treatment of the iliac or common femoral veins. At a median follow-up of 395 days (Q1: 205-Q3: 756 days), primary patency of femoropopliteal veins was 79.3% (95% CI 64.6-94.1%) and secondary patency was 82.8% (95% CI, 69.0-96.5%). The percentage of patients with moderate or severe PTS according to the Villalta score decreased from baseline to last follow-up from 34.5% to 18.5% and from 31% to 14.8%, respectively (p<0.003). Overall, the mean (SD) Villalta score decreased from 11.5 (1.7) to 8.0 (1.7) (p<0.0001). Postprocedural complete ulcer healing occurred in 4 out of 5 (80%) patients. Two (6.9%) patients developed new ulcers. No major bleeding, pulmonary embolism, stroke, or death occurred. Conclusion: PTA of femoropopliteal veins via posterior tibial or popliteal vein access appears to improve the severity of PTS with acceptable patency rates.

Sucrose Octasulfate-Impregnated Dressings for Adults With Difficult-to-Heal Noninfected Diabetic Foot Ulcers and Difficult-to-Heal Noninfected Venous Leg Ulcers: A Health Technology Assessment.

Background: Diabetic foot ulcers and venous leg ulcers may not always heal in a timely manner despite proper wound care. Treatments that improve the healing rate of these ulcers would improve clinical outcomes for patients and may result in downstream cost savings for the health care system. We conducted a health technology assessment of sucrose octasulfate-impregnated dressings for adults with difficult-to-heal noninfected diabetic foot ulcers and difficult-to-heal noninfected venous leg ulcers, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding sucrose octasulfate-impregnated dressings, and patient preferences and values. Methods: We performed a systematic literature search of the clinical evidence. We assessed the risk of bias of each included study using the Cochrane risk-of-bias tool for randomized trials (RoB 2) and the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic economic literature search and analyzed the budget impact of publicly funding sucrose octasulfate-impregnated dressings for adults with difficult-to-heal noninfected diabetic foot ulcers and difficult-to-heal noninfected venous leg ulcers in Ontario. We did not conduct a primary economic evaluation because there is existing evidence to approximate the cost-effectiveness of sucrose octasulfate-impregnated dressings in Ontario. We leveraged 4 previous health technology assessments to explore the perspectives and experiences of patients with diabetic foot ulcers and venous leg ulcers, as well as the perspectives and experiences of their care partners. Results: We included 3 randomized controlled trials and 2 subsequent publications of these randomized controlled trials in the clinical evidence review. Compared with dressings that do not contain sucrose octasulfate, sucrose octasulfate-impregnated dressings result in faster wound closure in patients with difficult-to-heal noninfected neuroischemic diabetic foot ulcers (GRADE: Moderate) and reduce ulcer size and improve health-related quality of life in the domains of pain/discomfort and anxiety/depression for patients with difficult-to-heal noninfected venous leg ulcers (GRADE: Moderate). The use of sucrose octasulfate-impregnated dressings with noninfected wounds is considered safe (GRADE: Moderate).The economic evidence showed that, compared with dressings that do not contain sucrose octasulfate, sucrose octasulfate-impregnated dressings are highly likely to be cost-effective for both difficult-to-heal noninfected diabetic foot ulcers and difficult-to-heal noninfected venous leg ulcers and would lead to cost savings due to faster and increased complete wound healing. The annual budget impact of publicly funding sucrose octasulfate-impregnated dressings in Ontario over the next 5 years would range from cost savings of $0.93 million in year 1 to $0.62 million in year 5 for adults with difficult-to-heal noninfected diabetic foot ulcers, and cost savings of $0.8 million in year 1 to $0.53 million in year 5 for adults with difficult-to-heal noninfected venous leg ulcers. Overall, we estimate that publicly funding sucrose octasulfate-impregnated dressings in Ontario for adults with difficult-to-heal noninfected diabetic foot ulcers and difficult-to-heal noninfected venous leg ulcers would lead to total cost savings of $3.91 million and $3.38 million, respectively, over the next 5 years.Patients with diabetic foot ulcers and venous leg ulcers discussed the effects of living with these wounds, as well as their treatment journey. They spoke about the burden of their condition and its negative impact on their daily lives, including mobility, employment, social activities, and mental health. Patients also spoke about the variety of treatment options available and the financial barriers to accessing these treatments. Conclusions: Sucrose octasulfate-impregnated dressings are safe and improve the healing of difficult-to-heal noninfected neuroischemic diabetic foot ulcers and difficult-to-heal noninfected venous leg ulcers compared with dressings that do not contain sucrose octasulfate. We estimate that publicly funding sucrose octasulfate-impregnated dressings in Ontario would result in cost savings for both difficult-to-heal noninfected diabetic foot ulcers and difficult-to-heal noninfected venous leg ulcers. Evidence from patient engagement suggests that people with diabetic foot ulcers or venous leg ulcers face negative impacts on their quality of life, especially related to mobility. Patients spoke about their challenges, including long and difficult care journeys, as well as trying different treatment options to heal their ulcers and avoid amputation. It is not clear if the participants had direct experience with sucrose octasulfate-impregnated dressings, so we could not draw specific conclusions about these dressings from the preferences and values evidence.

Comparison of two ablation procedures combined with high ligation and foam sclerotherapy and compression therapy for patients with venous leg ulcers.

AIM: To compare the ablation techniques' efficacy of endovenous microwave ablation (EMA) combined with high ligation (HL), foam sclerotherapy (FS) and compression therapy (CT) and endovenous laser ablation (EVLA) combined with HL-FS-CT in the treatment of VLUs. METHOD: 301 consecutive patients with VLUs from 2013 to 2022 in a 3200-bed hospital were intervened by EMA combined with HL-FS-CT and EVLA combined with HL-FS-CT were retrospectively compared. RESULTS: One hundred thirty-four patients underwent EMA+HL-FS-CT and 167 patients underwent EVLA+HL-FS-CT. The primary outcome of the ulcer healing time was 1.45(0.75-1.5) months and 1.86(0.5-2.5) months, respectively, in the two groups (HR for ulcer healing was 1.26, 95% CI [0.96-1.66], p = 0.097). Secondary outcomes included that no significant difference was found in ulcer recurrence and GSV recanalization and complications between the two groups, and the postoperative VCSS and AVVQ were significantly lower than the baseline values in the respective groups (p = 0.0001). CONCLUSION: EMA+HL-FS-CT and EVLA+HL-FS-CT are both effective at treating VLUs. Both of the two comprehensive treatments were beneficial to the healing of ulcers, but no evidence showed which one was superior in the ulcer healing time.

Integrating new approaches to care in a vascular wound clinic.

INTRODUCTION: An evidence-based approach is essential in the treatment of wounds to optimise healing, reduce costs and improve patient outcomes. AIM: This case study aimed to demonstrate our model of care, which assesses and manages patients with venous disease and complex wounds. In this case, venous leg ulcer (VLU) was treated with TLC-NOSF dressing and therapeutic compression. The wound was serially assessed using a smart App that gave the patient a graphic representation of their progress. DESIGN: Descriptive Observational Case Study. CLINICAL CARE: An evidence-based approach for managing a chronic, severe VLU. The patient was initially seen at the Outpatient Vascular Wound Clinic twice weekly, then every two weeks for conservative sharp wound debridement, skin care, dressing change, and compression therapy using a compression (Ready) wrap. Wound progress was monitored by the digital application 'Tissue Analytics', a "purposedesigned digital wound management platform that records, tracks, and analyses wounds". RESULTS: Week 1: On initial review, ulcer length was 3.15cm, width was 3.1 cm, and total surface area was 6.31 cm2. The wound base was mildly sloughy (<25%), with areas of good granulation tissue on view. Week 12: Length was 1.32 cm, width 1.50 cm, and total surface area of 1.45 cm2, a 77% reduction in wound size. Week 24: The length was 0.48 cm, the width was 0.64 cm, and the total surface area was 0.18 cm2. This represented a 97% reduction in wound size. Week 36: Length was 0.01 cm, the width 0.06 cm, with a total surface area of 0.00 cm2. This represented a 99.99% reduction in wound size. CONCLUSION: The patient's treatment for a complex venous leg ulcer included the application of TLC-NOSF dressing in combination with individualised therapeutic compression therapy. We found TLC-NOSF was very effective in combination with the best standard of VLU care (i.e. therapeutic graduated compression therapy). The clinician and patient were impressed with the healing rate at 12 weeks, as the wound dimensions were the lowest since the wound started six years ago. This dramatically improved patient concordance and engagement in care. Despite incomplete healing at 36 weeks, the wound-healing journey over the 36 weeks indicated wound closure was close. In addition, using a wound assessment App, the patient could immediately see the benefits of the new treatment, facilitating patient compliance with the treatment.

Effectiveness of the Use of the Human Recombinant Epidermal Growth Factor in the Subsidized Regime vs The Contributive Regime in Patients with Venous Ulcers in Bogotá.

Introduction: Vascular ulcers constitute a serious global public health problem, responsible for causing a significant social and economic impact due to their recurrent, disabling nature and the need for prolonged therapies to cure them. Objective: To evaluate the use and efficacy of the rhEGF in the epithelialization of patients with a diagnosis of CEAP stage 6 venous insufficiency, in the two regimes of the health system in Colombia, the contributive (equivalent to a health system where citizens with payment capacity contribute a percentage of their salary) and the subsidized (equivalent to a health system where the state covers the vulnerable population and low socioeconomic level) versus the other treatments used. Methodology: Observational, descriptive, retrospective, multicenter study, in which 105 medical records with 139 ulcers were reviewed, in 2 centers, one belonging to the subsidized system and the other to the contributive system in Colombia. Results: The association with the epithelialization variable of the different treatment groups for ulcers according to the application of the mixed effect model test, for both regimes was for the Biologicals (EC 34.401/p = 0.000), Bioactive Agents (Hydrogels) (EC 24.735/p = 0.005) groups; for the rest of the treatment groups, the results were neither associated nor statistically significant. Conclusion: Intra- and perilesional therapy with rhEGF expands the therapeutic spectrum in patients with venous ulcers, regardless of the type of health system in which it will be applied, shortening the healing time and reaching a possible therapeutic goal, which according to this study there is an association with epithelialization regardless of the regime applied.

Advancing nursing practice in Ireland: A pathway of care for nurse-led integrated venous leg ulcer management.

Approximately 80% of patients presenting with leg ulcers are venous in origin. However, lack of standardisation of care has a human and financial impact for patients and service providers. Increases in the aging population and number of patients entering older age with co-morbidities results in increases in the demand for venous leg ulcer treatments. A joint initiative between a Registered Advanced Nurse Practitioner (RANP) in tissue viability and wound care, and a vascular consultant, identified deficits in patient care delivery and quality of life. A joint initiative Implementing the principles of the 'Sláintecare' policy was established as the Leg Ulcer Centre Ireland (LUCI) to deliver a pathway for the treatment and management of lower limb venous ulcers. The RANP provides a "one stop shop" for patients, offering a complete care package from diagnosis to surgical intervention - endovenous ablation, follow-up post operative care and discharge. Audit findings include; reduced hospital admissions and waiting times; increased patient satisfaction; and, improved interdisciplinary integrated referral pathways. The RANP offers an effective, efficient diagnosis-to-end treatment service for patients. The results demonstrate improved treatment, cost outcomes and value-based outcomes for patients. The new integrated service facilitates expansion of the service and further enhancement of the nursing skills and role.

Review of Mixed Arterial Venous Leg Ulcers (MAVLU) Disease in Contemporary Practice.

BACKGROUND: Mixed Arterial and Venous Leg Ulcers (MAVLU) are challenging. Clinical evidence specific to MAVLU management is scarce. We evaluated our recent experience with MAVLU patients and reviewed current data regarding MAVLU epidemiology, aetiology, diagnostic assessment and management options. METHODS: A prospective leg ulcer database was retrospectively interrogated to determine the prevalence and clinical outcome of MAVLU over 2-year period (2021-2022). The literature was reviewed to determine if optimal treatment strategies. RESULTS: 307 patients attended the ulcer clinic over a 2-year period. Most were venous leg ulcers (71%), 24% were arterial and 5% were MAVLU. The highest healing rate was in MAVLU (93%), followed by (74%) and (41%), in arterial and venous leg ulcer groups, respectively. CONCLUSION: Evidence-based guidelines for MAVLU remain lacking. Well-developed randomised controlled trials are warranted to guide current clinical practice.
