Patients with venous leg ulcers can be managed safely in the community ----results of an observational comparison study in Singapore. J Tissue Viability 2024:S0965-206X(24)00114-1. [PMID: 39164151 DOI: 10.1016/j.jtv.2024.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 07/08/2024] [Accepted: 07/21/2024] [Indexed: 08/22/2024]
Abstract
AIM To examine the healing outcomes of patients with venous leg ulcers requiring compression bandaging in community care versus tertiary care. METHOD This was an analytical observational cohort study. Venous leg ulcer (VLU) patients who required compression bandaging were recruited from an outpatient vascular clinic between May 2021 and August 2022. Eligible patients received two-or four-layer compression bandaging and followed up with the community care or tertiary care centre nurses. The primary outcome was the difference in the total surface area of the VLU after 12 weeks, and the secondary outcome was the patient's quality of life, as measured by the Cardiff Wound Impact Schedule (CWIS). RESULTS Forty-seven VLU patients were recruited; 27 received compression bandaging in the community care and 20 by the tertiary care centre. Mean age 70 years old (SD 11.04). The two most prevalent comorbidities were hypertension (51.06 %) and diabetes mellitus (38.29 %). Among those who completed follow-up (12 weeks), the median difference of the total surface area of the VLU between community-based care (p = 0.02) versus tertiary-based care (0.003) was significant. However, there was no difference in the healing status between community and tertiary-based care (p = 0.68). There was no difference in the quality of life of patients between groups. CONCLUSION This first tropical study comparing VLU healing outcomes between community and tertiary care found no significant difference in healing with compression bandaging by nurses in either setting. However, the small sample size and high dropout rate limit the generalizability of the findings, necessitating a larger-scale study with longer follow-up. Despite these limitations, the study is a crucial step toward improving wound care services in Singapore, and highlights the need for further research to guide future community wound care implementation.

Abstract
OBJECTIVE To evaluate the use and performance of a gelling fibre dressing (Biatain Fiber; Coloplast A/S, Denmark) in the management of wounds in community nursing practice. METHOD A sub-analysis of the prospective, observational, real-world VIPES (Observatoire en Ville des Plaies ExSudatives) study was conducted. Patients with exuding wounds, for which nurses chose to apply the gelling fibre as a primary dressing, were included. Outcomes included assessments of wound condition and patient/nurse opinion. RESULTS Overall, 149 patients with acute (n=52; 34.9%) or hard-to-heal (chronic) (n=97; 65.1%) wounds were included. At baseline, mean±standard deviation wound age was 351.5±998.2 days, 108 (72.5%) wounds were moderately-to-highly exuding, and 126 (84.6%) showed exudate pooling in the wound bed. At the last follow-up visit, 29 (19.5%) wounds had healed, within a median of 36 days, and 64 (43.0%) were progressing towards healing. From baseline to the last follow-up visit, significant reductions in wound surface area (p<0.05), depth (p<0.01), exudate level (p<0.0001), and in the proportion of wounds with sloughy tissue (p<0.0001) were observed. Most wounds had no (n=86; 58.5% (two missing values)) or low exudate pooling (n=45; 30.6% (two missing values)) at the last visit and proportions of patients with healthy wound edges/periwound skin increased from baseline. At the last visit, wounds were considered improved by nurses in 71.4% (n=105) of cases, and by patients in 66.7% (n=98) of cases (two patients missing). CONCLUSION Patients who received treatment with the gelling fibre experienced improvements in the condition of a range of complex wounds. This analysis highlights the importance of adequate exudate management, and indicates how the selection of an appropriate wound dressing can encourage healing progression.

Abstract
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.

Abstract
Aim To explore the relationship between physical activity levels and wound healing and recurrence in people with venous leg ulcers. Methods Questionnaires and medical records were used to collect data, with responses used to group participants into different physical activity groups. The differences in healing and recurrence outcomes of ulcers among different physical activity groups were compared using Chi-square, Kaplan Meier survival analysis, Cox proportional hazards regression analysis, and Kruskal-Wallis test. To measure the strength of the association between physical activity levels and patient outcomes, Spearman's Rho tests were used. We used descriptive analysis to examine how physical activity levels change over 24 weeks. Results Participants were classified into four distinct groups based on physical activity levels reported at baseline and week 12. The survival analysis showed higher physical activity level was associated with a shorter time to healing (log-rank test = 14.78, df = 3; p = 0.002). The persistently moderate-to-vigorous group had a 7.3-fold increased likelihood of healing compared to the persistently sedentary group. High levels of physical activity were also associated with a better quality of life score at baseline (ρ = 0.41, p < 0.000), week 12 (ρ = 0.36, p < 0.001), and week 24 (ρ = 0.49, p < 0.000). Most participants (48.5%) reported low levels of physical activity, which remained low for the entire study period. Conclusion An increased level of physical activity was linked to a shorter healing time and enhanced quality of life. Low levels of physical activity appeared common among people with venous leg ulcers.

Abstract
In the current era of increasing emphasis on diversity, inclusion, and equity, it is of utmost importance for vascular surgeons to be cognizant of the increasingly diverse population in the United States. We should try our best to ensure the same quality of vascular care to all our patients, regardless of their backgrounds. It is humanly impossible to expect any of us to have a deep understanding of all the cultures, and that is not the point of this essay. The key lesson from this essay is that we should be able to recognize that patients from different backgrounds may have different expectations from us and we should try to meet those expectations to the best of our abilities.

Abstract
Venous leg ulceration results in significant morbidity. However, the majority of studies conducted are on Western populations. This study aims to evaluate the wound healing and quality of life for patients with venous leg ulcers (VLUs) in a Southeast Asian population. This is a multi-centre prospective cohort study from Nov 2019 to Nov 2021. All patients were started on 2- or 4-layer compression bandage and were reviewed weekly or fortnightly. Our outcomes were wound healing, factors predictive of wound healing and the EuroQol 5-dimensional 5-level (EQ-5D-5L) health states. Within our cohort, there were 255 patients with VLU. Mean age was 65.2 ± 11.6 years. Incidence of diabetes mellitus was 42.0%. Median duration of ulcer at baseline was 0.30 years (interquartile range 0.136-0.834). Overall, the median time to wound healing was 4.5 months (95% confidence interval [CI]: 3.77-5.43). The incidence of complete wound healing at 3- and 6-month was 47.0% and 60.9%, respectively. The duration of the wound at baseline was independently associated with worse wound healing (Hazard ratio 0.94, 95% CI: 0.89-0.99, P = .014). Patients with healed VLU had a significantly higher incidence of perfect EQ-5D-5L health states at 6 months (57.8% vs 13.8%, P < .001). We intend to present longer term results in subsequent publications.

Abstract
BACKGROUND There is no agreed treatment pathway following excision of keratinocyte cancer (KC). Compression therapy is considered beneficial for secondary intention healing on the lower leg; however, there is a lack of supportive evidence. To plan a randomized controlled trial (RCT), suitable data are needed. We report a multicentre prospective observational cohort study in this patient population with the intention of informing a future trial design. AIM To estimate the time to healing in wounds healing by secondary intention without planned postoperative compression, following excision of KC on the lower leg; to characterize the patient population, including factors affecting healing; and to assess the incidence of complications. METHODS This was a multicentre prospective observational cohort study. Inclusion criteria were age ≥ 18 years with planned excision of KC on the lower leg and healing by secondary intention, an ankle-brachial pressure index (ABPI) of ≥ 0.8; and written informed consent. Exclusion criteria included planned excision with primary closure, skin graft or flap; compression therapy for another indication; planned compression; inability of patient to receive, comply with or tolerate high compression; or a suspected diagnosis other than KC. RESULTS This study recruited 58 patients from 9 secondary care dermatology clinics. In the analysis population (n = 53), mean age was 81 years (range 25-97 years), median time to healing was 81 days (95% CI 73-92) and 45 patients (84.9%) had healing of the wound at the 6-month follow-up. The healing prognostic factors were wound parameters and ABPI. Wound infections occurred in 16 participants (30.2%). Four patients (7.5%) were admitted to hospital; three because of an infection and one because of a fall. CONCLUSIONS The collected data have informed the RCT preparation. A relatively high proportion (7.5-15%) of unhealed wounds, infection and hospital admissions demonstrate the need for clearly establishing potentially effective treatments to improve outcomes for this population.

Synthesizing time-series wound prognosis factors from electronic medical records using generative adversarial networks. J Biomed Inform 2021; 125:103972. [PMID: 34920125 DOI: 10.1016/j.jbi.2021.103972] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 09/20/2021] [Accepted: 12/03/2021] [Indexed: 11/26/2022]
Abstract
Wound prognostic models not only provide an estimate of wound healing time to motivate patients to follow up their treatments but also can help clinicians to decide whether to use a standard care or adjuvant therapies and to assist them with designing clinical trials. However, collecting prognosis factors from Electronic Medical Records (EMR) of patients is challenging due to privacy, sensitivity, and confidentiality. In this study, we developed time series medical generative adversarial networks (GANs) to generate synthetic wound prognosis factors using very limited information collected during routine care in a specialized wound care facility. The generated prognosis variables are used in developing a predictive model for chronic wound healing trajectory. Our novel medical GAN can produce both continuous and categorical features from EMR. Moreover, we applied temporal information to our model by considering data collected from the weekly follow-ups of patients. Conditional training strategies were utilized to enhance training and generate classified data in terms of healing or non-healing. The ability of the proposed model to generate realistic EMR data was evaluated by TSTR (test on the synthetic, train on the real), discriminative accuracy, and visualization. We utilized samples generated by our proposed GAN in training a prognosis model to demonstrate its real-life application. Using the generated samples in training predictive models improved the classification accuracy by 6.66-10.01% compared to the previous EMR-GAN. Additionally, the suggested prognosis classifier has achieved the area under the curve (AUC) of 0.875, 0.810, and 0.647 when training the network using data from the first three visits, first two visits, and first visit, respectively. These results indicate a significant improvement in wound healing prediction compared to the previous prognosis models.

Abstract
Venous leg ulcerations are a common problem, with high prevalence in the middle-aged and elderly population, and more attention on research of their physical activities has been paid, as they have great effects on the blood circulation of the lower limb. With enough, appropriate training, the chronic venous ulcerations in the lower limb can be avoided and alleviated, and venous hypertension can be reduced effectively. The study deals with a physical activity tracking system for the patients based on a three-axis accelerometer. The system uses a three-axis accelerometer, a microcontroller, and a wireless Bluetooth module to form a data acquisition platform to acquire accelerations of the lower limb movement, and sends it to a smart mobile phone via the wireless Bluetooth module. The system takes advantages of the smart mobile phone to guide the chronic venous leg ulcers to do prescribed rehabilitation exercises for the lower limb muscles, perform acceleration data preprocessing, wavelet transform and reconstruction, denoising and feature extraction, obtain the results of the rehabilitation exercises, and then give reasonable evaluation and judgment. It is helpful to treat underlying venous reflux, create such an environment that allows skin to grow across an ulcer, and accelerate ulcer healing process consequently.

Abstract
BACKGROUND Despite regular treatment of venous leg ulcers (VLUs), some fail to heal. Although several risk factors have previously been identified to be associated with the failure of VLUs to heal, the majority of studies are limited to <24-week follow-up. METHODS A retrospective cohort study was performed at an academic vascular and wound center. A total of 65 patients with VLUs who were observed for a year or more were identified. These patients underwent a variety of treatments following the Society for Vascular Surgery and American Venous Forum VLU guidelines. Risk factors, which were based on previously defined elements for failure of VLUs to heal after a period of treatment, were examined. Both univariate (unadjusted) and multivariate (adjusted) logistic regression analyses were used to assess the magnitude of effect that a given risk factor had on healing. RESULTS Of 65 patients treated for a minimum of 52 weeks, 19 (29%) remained unhealed. By univariate analysis, deep venous disease (P = .01; odds ratio [OR], 5.82; 95% confidence interval [CI], 1.49-22.72), history of deep venous thrombosis (P < .001; OR, 14.06; 95% CI, 3.77-52.39), and depression (P = .04; OR, 3.89; 95% CI, 1.10-13.80) were all shown to be significant risk factors for nonhealing. The patient's race (ie, being nonwhite; P = .02; OR, 103.45; 95% CI, 1.94-5.53 × 103), deep venous disease (P = .05; OR, 37.0; 95% CI, 1.05-1.31 × 103), and history of deep venous thrombosis (P = .01; OR, 122.4; 95% CI, 3.09-4.84 × 103), however, were all shown to be significant for nonhealing under multivariate analysis. In addition, identification of an incompetent perforator (P = .02; OR, 0.006; 95% CI, 9.27 × 10-5-0.44) was conversely shown to be a good prognostic factor for healing. CONCLUSIONS This study confirmed that risk factors known to be associated with the failure of a VLU to heal-deep venous disease and post-thrombotic etiology-were significant at 52 weeks, whereas depression and race (nonwhite) are novel risk factors. An analysis of markers of access to care showed no difference between white and nonwhite, suggesting other factors as a cause. The predominance of deep venous disease in the unhealed vs healed cohort (84% vs 48%) highlights the need for a viable treatment option for deep venous disease due to reflux. Overall, this study emphasizes the need to consider all risk factors when evaluating a patient for VLU to coordinate an effective treatment plan and to identify gaps in our treatment.
