Quality of Life in Patients with Venous Leg Ulcers Treated by Means of Local Hyperbaric Oxygen Therapy or Local Ozone Therapy-A Single Center Study. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:2071. [PMID: 38138174 PMCID: PMC10744587 DOI: 10.3390/medicina59122071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 11/18/2023] [Accepted: 11/22/2023] [Indexed: 12/24/2023]
Abstract
Background and Objectives: Venous leg ulcers pose a significant medical problem worldwide. The complexity of the problem determines the need for further interdisciplinary activities that will improve the quality of life for treated patients. This study compared the quality of life of patients with venous leg ulcers who received local hyperbaric oxygen therapy or local ozone therapy procedures as part of comprehensive treatment. Materials and Methods: The study included 129 patients (62 men and 57 women) with venous leg ulcers. Group I underwent local hyperbaric oxygen therapy (HBOT), and Group II underwent local ozone therapy (OZONE). In both groups, the patients' quality of life was assessed before the start of the treatment cycle, as well as 10 weeks and 6 months after the completion of the treatment, by means of the EQ-5D-5L questionnaire and the Polish shortened version of the SF-36 scale. Results: After completing the respective therapeutic cycle, both groups showed statistically significant (p < 0.001) improvement in quality of life, according to the EQ-5D-5L questionnaire and the SF-36 scale. Differences were noted between the 1st examination (before treatment) and the 2nd examination (10 weeks after treatment), as well as the 3rd examination (6 months after treatment). In the EQ-5D-5L assessment of anxiety and depression, self-care, and activities of daily living 6 months after the end of treatment, better results were found in the group of patients treated with local hyperbaric oxygen therapy (p < 0.001). In this group, 6 months after the end of the treatment, a statistically significantly higher result on the EQ-VAS scale was also obtained (73.09 ± 19.8 points vs. 68.03 ± 17.37 points, p = 0.043). However, in the SF-36 assessment performed 6 months after the end of treatment, better results-a statistically significantly lower value of the quality of life index-were recorded in the group of patients treated with local ozone therapy (103.13 ± 15.76 points vs. 109.89 ± 15.42 points, p < 0.015). Conclusions: Hyperbaric oxygen therapy and local ozone therapy procedures have a beneficial effect on improving the quality of life of patients with venous leg ulcers.

Abstract
BACKGROUND Venous leg ulcers (VLUs) are a serious manifestation of chronic venous disease affecting up to 3% of the adult population. This typically recalcitrant and recurring condition significantly impairs quality of life, and its treatment places a heavy financial burden upon healthcare systems. The longstanding mainstay treatment for VLUs is compression therapy. Surgical removal of incompetent veins reduces the risk of ulcer recurrence. However, open surgery is an unpopular option amongst people with VLU, and many people are unsuitable for it. The efficacy of the newer, minimally-invasive endovenous techniques has been established in uncomplicated superficial venous disease, and these techniques can also be used in the management of VLU. When used with compression, endovenous ablation aims to further reduce pressure in the veins of the leg, which may impact ulcer healing. OBJECTIVES To determine the effects of superficial endovenous ablation on the healing and recurrence of venous leg ulcers and the quality of life of people with venous ulcer disease. SEARCH METHODS In April 2022 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scrutinised reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions on the language of publication, but there was a restriction on publication year from 1998 to April 2022 as superficial endovenous ablation is a comparatively new technology. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing endovenous ablative techniques with compression versus compression therapy alone for the treatment of VLU were eligible for inclusion. Studies needed to have assessed at least one of the following primary review outcomes related to objective measures of ulcer healing such as: proportion of ulcers healed at a given time point; time to complete healing; change in ulcer size; proportion of ulcers recurring over a given time period or at a specific point; or ulcer-free days. Secondary outcomes of interest were patient-reported quality of life, economic data and adverse events. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed studies for eligibility, extracted data, carried out risk of bias assessment using the Cochrane RoB 1 tool, and assessed GRADE certainty of evidence. MAIN RESULTS The previous version of this review found no RCTs meeting the inclusion criteria. In this update, we identified two eligible RCTs and included them in a meta-analysis. There was a total of 506 participants with an active VLU, with mean durations of 3.1 months ± 1.1 months in the EVRA trial and 60.5 months ± 96.4 months in the VUERT trial. Both trials randomised participants to endovenous treatment and compression or compression alone, however the compression alone group in the EVRA trial received deferred endovenous treatment (after ulcer healing or from six months). There is high-certainty evidence that combined endovenous ablation and compression compared with compression therapy alone, or compression with deferred endovenous treatment, improves time to complete ulcer healing (pooled hazard ratio (HR) 1.41, 95% CI 1.36 to 1.47; I2 = 0%; 2 studies, 466 participants). There is moderate-certainty evidence that the proportion of ulcers healed at 90 days is probably higher with combined endovenous ablation and compression compared with compression therapy alone or compression with deferred endovenous treatment (risk ratio (RR) 1.14, 95% CI 1.00 to 1.30; I2 = 0%; 2 studies, 466 participants). There is low-certainty evidence showing an unclear effect on ulcer recurrence at one year in people with healed ulcers with combined endovenous treatment and compression when compared with compression alone or compression with deferred endovenous treatment (RR 0.29, 95% CI 0.03 to 2.48; I2 = 78%; 2 studies, 460 participants). There is also low-certainty evidence that the median number of ulcer-free days at one year may not differ (306 (interquartile range (IQR) 240 to 328) days versus 278 (IQR 175 to 324) days) following combined endovenous treatment and compression when compared with compression and deferred endovenous treatment; (1 study, 450 participants). There is low-certainty evidence of an unclear effect in rates of thromboembolism between groups (RR 2.02, 95% CI 0.51 to 7.97; I2 = 78%, 2 studies, 506 participants). The addition of endovenous ablation to compression is probably cost-effective at one year (99% probability at GBP 20,000/QALY; 1 study; moderate-certainty evidence). AUTHORS' CONCLUSIONS Endovenous ablation of superficial venous incompetence in combination with compression improves leg ulcer healing when compared with compression alone. This conclusion is based on high-certainty evidence. There is moderate-certainty evidence to suggest that it is probably cost-effective at one year and low certainty evidence of unclear effects on recurrence and complications. Further research is needed to explore the additional benefit of endovenous ablation in ulcers of greater than six months duration and the optimal modality of endovenous ablation.

Chronic Venous Insufficiency With Emphasis on the Geriatric Population. Cureus 2023; 15:e40687. [PMID: 37485203 PMCID: PMC10358300 DOI: 10.7759/cureus.40687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 06/13/2023] [Indexed: 07/25/2023] Open
Abstract
The underpinning of Chronic Venous Insufficiency (CVI) is valvular dysfunction, which manifests on a spectrum depending on the severity of insufficiency and duration of the disease. The mainstay of treatment relies on compression therapy of a proper type and intensity. In older adults, special consideration must be taken during the patient encounter to account for age-related factors. This review discusses the clinical presentation, diagnosis, and mimicking of CVI, focusing mainly on older adults. The epidemiology, risk factors, disease burden, and grave complications -- such as thrombosis and ulceration, are reviewed. The physiological impacts of CVI are described, providing the background for treatment strategies, including non-invasive, medical, and surgical therapies. The findings show advanced age to be an important risk factor contributing to CVI and that other age-related factors add to the risk of severe complications. Clinical assessments combined with objective measurements that assess localized skin water using tissue dielectric constant values or whole limb assessments may aid in the differential diagnosis. Furthermore, understanding the mechanism of action of compression therapy, the mainstay of CVI treatment, and its physiological impacts, allows for its informed use in geriatric patients with increased risks of potential compression-related side effects.

Abstract
OBJECTIVE Symptoms and treatment of venous leg ulcers (VLUs) adversely impact patients' quality of life (QoL). There is no QoL tool that considers the linguistic and cultural specificities of patients with VLU in Taiwan. This study aimed to evaluate the psychometric properties of the traditional Chinese version of the Venous Leg Ulcer Quality of Life Questionnaire (VLU-QoL). METHODS The processes of translation and cultural adaptation of the VLU-QoL from English to traditional Chinese included forward translation, back translation, linguistic modification, and expert review. Using a sample of 167 patients with VLU from a hospital in southern Taiwan, the psychometric properties analyzed were internal consistency, test-retest reliability, content validity, convergent validity, and criterion-related. RESULTS The traditional Chinese version of the VLU-QoL demonstrated good overall internal consistency (Cronbach α = .95) and overall test-retest reliability coefficient (r = 0.98). Confirmatory factor analysis was used to assess the convergent validity of the scale; results showed that the Activity, Psychology, and Symptom Distress constructs had acceptable fit and a structure similar to that of the original scale. The scale had its criterion-related validity verified using the Taiwanese version of the 36-item Short-Form Health Survey, demonstrating a good correlation coefficient r that ranged from -0.7 to -0.2 (P < .001). CONCLUSIONS The Chinese version of the VLU-QoL is valid and reliable for assessing the QoL in patients with VLU, delivering a tool that nurses can use to deliver timely and appropriate care to improve patients' QoL.

Abstract
Objective: Complex hard-to-heal wounds are difficult to manage, generating significant expense to the US healthcare system, costing nearly $25 billion annually. Recently, a resorbable synthetic nanofibre matrix was trialled on a variety of complex hard-to-heal wounds at Astria Sunnyside Hospital to assess clinical efficacy. Method: In this case series, five patients with multiple comorbidities presented in both the inpatient and outpatient setting with various hard-to-heal refractory wounds, including a venous leg ulcer (n=1), a diabetic foot ulcer (n=1), a Charcot foot deformity (n=1) and pressure ulcers (n=2). In an effort to treat these hard-to-heal wounds using a different treatment modality, each patient was transitioned to a care regimen utilising the synthetic nanofibre matrix. Results: Each patient, regardless of wound type, exhibited the formation of granulation tissue and a reduction in wound size. The application of this synthetic nanofibre matrix also resulted in tissue coverage over exposed structure in three cases, reduction of wound exudate in two cases, and eliminated a recurring infection with and without antibiotics in four cases. Conclusion: In this study, the treatment of hard-to-heal refractory wounds with the synthetic nanofibre matrix resulted in the desired biological responses and new tissue formation. Inclusion of the nanofibre matrix in inpatient and outpatient wound care settings may provide a much-needed solution for costly, difficult-to-treat, hard-to-heal wounds, and may offer a reduction in the total cost of care.

Abstract
OBJECTIVE This study evaluated the impact of four weeks of treatment with Prontosan Wound Irrigation Solution and Prontosan Wound Gel (B. Braun Medical Inc., US) on adults with hard-to-heal leg wounds. Overall change (weeks 1-5) in the Global Quality of Life scale (GQOL), changes in body, psyche and everyday life (EDL) quality of life (QoL) subscores, and changes in wound appearance and size after treatment were assessed. METHOD In this prospective, open-label, single-arm, five-centre study, non-hospitalised patients with no more than two wounds below the knee were recruited into the study; wounds were ≥5cm2 and ≤50cm2 and present for ≥4 weeks. The investigator or a designee applied the wound solution and gel to the wounds at clinic visits, and patients/caregivers applied the wound solution and gel at home. Wound-QoL questionnaires were completed at the initial screening and at each week of treatment. Wound size and photographs were obtained at pre- and post-treatment during clinic visits. RESULTS A total of 43 patients were enrolled in the study. Mean GQOL scores decreased by 1.11 (46.1%). Body, psyche and EDL decreased by 1.17 (60.0%), 1.26 (41.8%) and 1.00 (42.2%), respectively. Wounds also showed improvement in odour, appearance and size. Adverse events were mild in intensity and transient in nature. CONCLUSION This study demonstrated marked improvement in the QoL of patients with hard-to-heal leg wounds below the knee during four weeks of treatment with the wound solution and gel. Wounds also showed improvement in odour, appearance and size, and the treatment solution and gel were well tolerated. DECLARATION OF INTEREST B.

Abstract
Living with chronic ulcers can be burdensome and restrictive, with regard to not only physical and psychological but also social well-being. This review aims to analyse social participation in patients with chronic wounds and to compare results across different wound types. A search string was applied in several electronic databases. Results were screened according to predefined inclusion and exclusion criteria. Data of eligible articles were extracted and synthesised narratively. The search revealed 42 eligible publications. Only minor differences across different ulcer types could be detected. Overall, family members were the main social contacts for patients; they often provided wound care and emotional support. Patients had few non-family relations, but those existing were often very close. Patients felt guilty as their condition imposed burden on family and friends, as well. A close relationship with nurses was described. Restrictions were caused by direct and indirect consequences of the wound. Overall, social support and social connections were reduced in wound patients. Inconsistent results were found regarding social isolation. In summary, people with chronic wounds experience impairments in all aspects of social participation. Therefore, social participation deserves increased attention in routine care both as a trigger of burden and as an outcome of therapy.

Configuration of vascular services: a multiple methods research programme. PROGRAMME GRANTS FOR APPLIED RESEARCH 2021.

Abstract
Background
Vascular services is changing rapidly, having emerged as a new specialty with its own training and specialised techniques. This has resulted in the need for reconfiguration of services to provide adequate specialist provision and accessible and equitable services.
Objectives
To identify the effects of service configuration on practice, resource use and outcomes. To model potential changes in configuration. To identify and/or develop electronic data collection tools for collecting patient-reported outcome measures and other clinical information. To evaluate patient preferences for aspects of services other than health-related quality of life.
Design
This was a multiple methods study comprising multiple systematic literature reviews; the development of a new outcome measure for users of vascular services (the electronic Personal Assessment Questionnaire – Vascular) based on the reviews, qualitative studies and psychometric evaluation; a trade-off exercise to measure process utilities; Hospital Episode Statistics analysis; and the development of individual disease models and a metamodel of service configuration.
Setting
Specialist vascular inpatient services in England.
Data sources
Modelling and Hospital Episode Statistics analysis for all vascular inpatients in England from 2006 to 2018. Qualitative studies and electronic Personal Assessment Questionnaire – Vascular evaluation with vascular patients from the Sheffield area. The trade-off studies were based on a societal sample from across England.
Interventions
The data analysis, preference studies and modelling explored the effect of different potential arrangements for service provision on the resource use, workload and outcomes for all interventions in the three main areas of inpatient vascular treatment: peripheral arterial disease, abdominal aortic aneurysm and carotid artery disease. The electronic Personal Assessment Questionnaire – Vascular was evaluated as a potential tool for clinical data collection and outcome monitoring.
Main outcome measures
Systematic reviews assessed quality and psychometric properties of published outcome measures for vascular disease and the relationship between volume and outcome in vascular services. The electronic Personal Assessment Questionnaire – Vascular development considered face and construct validity, test–retest reliability and responsiveness. Models were validated using case studies from previous reconfigurations and comparisons with Hospital Episode Statistics data. Preference studies resulted in estimates of process utilities for aneurysm treatment and for travelling distances to access services.
Results
Systematic reviews provided evidence of an association between increasing volume of activity and improved outcomes for peripheral arterial disease, abdominal aortic aneurysm and carotid artery disease. Reviews of existing patient-reported outcome measures did not identify suitable condition-specific tools for incorporation in the electronic Personal Assessment Questionnaire – Vascular. Reviews of qualitative evidence, primary qualitative studies and a Delphi exercise identified the issues to be incorporated into the electronic Personal Assessment Questionnaire – Vascular, resulting in a questionnaire with one generic and three disease-specific domains. After initial item reduction, the final version has 55 items in eight scales and has acceptable psychometric properties. The preference studies showed strong preference for endovascular abdominal aortic aneurysm treatment (willingness to trade up to 0.135 quality-adjusted life-years) and for local services (up to 0.631 quality-adjusted life-years). A simulation model with a web-based interface was developed, incorporating disease-specific models for abdominal aortic aneurysm, peripheral arterial disease and carotid artery disease. This predicts the effects of specified reconfigurations on workload, resource use, outcomes and cost-effectiveness. Initial exploration suggested that further reconfiguration of services in England to accomplish high-volume centres would result in improved outcomes, within the bounds of cost-effectiveness usually considered acceptable in the NHS.
Limitations
The major source of evidence to populate the models was Hospital Episode Statistics data, which have limitations owing to the complexity of the data, deficiencies in the coding systems and variations in coding practice. The studies were not able to address all of the potential barriers to change where vascular services are not compliant with current NHS recommendations.
Conclusions
There is evidence of potential for improvement in the clinical effectiveness and cost-effectiveness of vascular services through further centralisation of sites where major vascular procedures are undertaken. Preferences for local services are strong, and this may be addressed through more integrated services, with a range of services being provided more locally. The use of a web-based tool for the collection of clinical data and patient-reported outcome measures is feasible and can provide outcome data for clinical use and service evaluation.
Future work
Further evaluation of the economic models in real-world situations where local vascular service reconfiguration is under consideration and of the barriers to change where vascular services do not meet NHS recommendations for service configuration is needed. Further work on the electronic Personal Assessment Questionnaire – Vascular is required to assess its acceptability and usefulness in clinical practice and to develop appropriate report formats for clinical use and service evaluation. Further studies to assess the implications of including non-health-related preferences for care processes, and location of services, in calculations of cost-effectiveness are required.

Abstract
People with hard-to-heal leg ulcers experience reduced quality of life (QoL), including physical, mental and social aspects; this, in turn, negatively affects the wound healing process. QoL is often overlooked by health professionals treating those with hard-to-heal wounds, for whom the focus is instead on the wound itself and the healing process. This study aimed to investigate how the QoL of patients with hard-to-heal wounds is documented and followed up by nurses. The healthcare records of patients with hard-to-heal wounds were reviewed using an audit instrument. Data were collected retrospectively from 12 patient healthcare records. The nursing documentation included few notes related to patients' QoL. The nurses focused on issues such as nutrition, mobilisation and smoking, while the patients expressed concerns about anxiety/depressed mood, pain and sleeping difficulties. Only nine of the documented problems were approved according to the instrument. Most importantly, documentation of planned interventions and outcomes was missing. Documentation by nurses around the QoL of patients with hard-to-heal wounds is lacking, because of which QoL might be neglected and wound healing might not progress well.

Abstract
Background: The aim of the study was to analyze the dynamics of pain severity and its predictors in a group of patients with chronic venous leg ulcers. Methods: A 12-week longitudinal study included 754 patients with chronic venous leg ulcers. Subjective severity of pain was measured at weekly intervals with an 11-point visual analogue scale (VAS). Results: A significant decrease in VAS scores has been observed throughout the entire analyzed period. Higher severity of pain during follow-up was independently predicted by the presence of pus and/or unpleasant smell from the ulceration during the first visit, as well as by the occurrence of posterior and/or circumferential ulcers. The presence of ulcer redness during the first visit was associated with lesser pain severity; also, a significant interaction effect between the ulceration redness and warmth was observed. Conclusions: Implementation of complex holistic care may contribute to a substantial decrease in the occurrence and severity of pain in a patient with venous leg ulcers. Pain control seems to depend primarily on clinical parameters and topography of venous ulcers. The predictors of pain severity identified in this study might be considered during the planning of tailored care for patients with venous leg ulcers.

Abstract
Background: The aims of this review are to analyze the current literature regarding the characteristics and pathophysiological mechanisms of itch in chronic wounds, to assess the impact on quality of life and delayed-healing, to focus on the best strategies of prevention and treatment, to highlight the importance of on-going research in order to fully understand the pathophysiology, and to improve the management of target therapies. Methods: A systematic literature review was performed using MEDLINE, PubMed, Embase, Scopus, ScienceDirect, and the Cochrane Library. We included a total of 11 articles written in English with relevant information on the pathophysiology of itch in chronic wounds and on management strategies. Results: Itch in chronic wounds was found to be correlated with xerosis, larger wound areas, necrotic tissue and amount of exudate, peripheral tissue edema, sclerosis, granulation tissue, contact dermatitis, and bacterial burden, as well as with lower quality of life. Conclusions: Although there are several aspecific pharmacological and non-pharmacological approaches, there appears to be no validated prevention or management strategy for itch in chronic wounds. Further studies are needed to clarify the association and pathophysiology of itch in chronic wounds, to evaluate the safety and efficacy of topical treatments on perilesional skin to reduce itch, to characterize multidimensional sensations of itch in chronic wounds, to identify specific cytokine and chemokine expressions that are correlated to a tailored-based approach, and to develop practical guidelines.

Abstract
The aim of this study was to translate into Mexican Spanish, cross-culturally adapt and validate the wound-specific quality of life (QoL) instrument Cardiff wound impact schedule (CWIS) for Mexican patients. This instrument went through the full linguistic translation process based on the guidelines of Beaton et al (Beaton DE, Bombardier C, Guillemin F, Ferraz MB, Guidelines for the process of cross-cultural adaptation of self-report measures, Spine Phila Pa, 1976, 2000, 318-391). We included a total of 500 patients with chronic leg ulcers. The expert committee evaluated the Face validity and they agreed unanimously that the instrument was adequate to assess the QoL of these patients, covering all relevant areas presented by them. The content validity index obtained was of 0.95. The construct validity demonstrated moderately significant correlations between related sub-scales of CWIS and SF-36 (P = .010 to P < .001). The instrument was able to discriminate between healed and unhealed ulcers. The instrument obtained an overall Cronbach's alpha of .952, corresponding to an excellent internal consistency (.903-.771 alpha range for domains). The CWIS can be appropriately used to assess the health-related QoL of Mexican patients with chronic leg ulcers.

Biobehavioral Mechanisms Associated With Nonhealing Wounds and Psychoneurologic Symptoms (Pain, Cognitive Dysfunction, Fatigue, Depression, and Anxiety) in Older Individuals With Chronic Venous Leg Ulcers.

Abstract
The prevalence and incidence of chronic venous leg ulcers (CVLUs) are increasing worldwide, as are the associated financial costs. Although it has long been known that their underlying etiology is venous insufficiency, the molecular aspects of healing versus nonhealing, as well as the psychoneurologic symptoms (PNS; pain, cognitive dysfunction, fatigue, depression, and anxiety) associated with CVLUs remain understudied. In this biobehaviorally focused review, we aim to elucidate the complex mechanisms that link the biological and molecular aspects of CLVUs with their PNS. Innovations in "omics" research have increased our understanding of important wound microenvironmental factors (e.g., inflammation, microbial pathogenic biofilm, epigenetic processes) that may adversely alter the wound bed's molecular milieu so that microbes evade immune detection. Although these molecular factors are not singularly responsible for wound healing, they are major components of wound development, nonhealing, and PNS that, until now, have not been amenable to systematic study, especially over time. Further, this review explores our current understanding of the molecular mechanisms by which the immune activation that contributes to the development and persistence of CVLUs also leads to the development, persistence, and severity of wound-related PNS. We also make recommendations for future research that will expand the field of biobehavioral wound science. Biobehavioral research that focuses on the interrelated mechanisms of PNS will lead to symptom-management interventions that improve quality of life for the population burdened by CVLUs.

Abstract
BACKGROUND Venous leg ulcers are complex, costly, and their prevalence is expected to increase as populations age. Venous congestion is a possible cause of venous leg ulcers, which subfascial endoscopic perforator surgery (SEPS) attempts to address by removing the connection between deep and superficial veins (perforator veins). The effectiveness of SEPS in the treatment of venous leg ulcers, however, is unclear. OBJECTIVES To assess the benefits and harms of subfascial endoscopic perforator surgery (SEPS) for the treatment of venous leg ulcers. SEARCH METHODS In March 2018 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA We included randomised controlled trials (RCTs) of interventions that examined the use of SEPS independently or in combination with another intervention for the treatment of venous leg ulcers. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies for inclusion, extracted data, assessed risk of bias, and assessed the certainty of evidence using the GRADE approach. MAIN RESULTS We included four RCTs with a total of 322 participants. There were three different comparators: SEPS plus compression therapy versus compression therapy (two trials); SEPS versus the Linton procedure (a type of open surgery) (one trial); and SEPS plus saphenous surgery versus saphenous surgery (one trial). The age range of participants was 30 to 82, with an equal spread of male and female participants. All trials were conducted in hospital settings with varying durations of follow-up, from 18 months to 6 years. One trial included participants who had both healed and active ulcers, with the rest including only participants with active ulcers.There was the potential for reporting bias in all trials and performance bias and detection bias in three trials. Participants in the fourth trial received one of two surgical procedures, and this study was at low risk of performance bias and detection bias.SEPS + compression therapy versus compression therapy (2 studies; 208 participants)There may be an increase in the proportion of healed ulcers at 24 months in people treated with SEPS and compression therapy compared with compression therapy alone (risk ratio (RR) 1.17, 95% confidence interval (CI) 1.03 to 1.33; 1 study; 196 participants); low-certainty evidence (downgraded twice, once for risk of bias and once for imprecision).It is uncertain whether SEPS reduces the risk of ulcer recurrence at 24 months (RR 0.85, 95% CI 0.26 to 2.76; 2 studies; 208 participants); very low-certainty evidence (downgraded three times, twice for very serious imprecision and once for risk of bias).The included trials did not measure or report the following outcomes; time to complete healing, health-related quality of life (HRQOL), adverse events, pain, duration of hospitalisation, and district nursing care requirements.SEPS versus Linton approach (1 study; 39 participants)It is uncertain whether there is a difference in ulcer healing at 24 months between participants treated with SEPS and those treated with the Linton procedure (RR 0.95, 95% CI 0.83 to 1.09; 1 study; 39 participants); very low-certainty evidence (downgraded three times, twice for very serious imprecision and once for risk of bias).It is also uncertain whether there is a difference in risk of recurrence at 60 months: (RR 0.47, 95% CI 0.10 to 2.30; 1 study; 39 participants); very low-certainty evidence (downgraded three times, twice for very serious imprecision and once for risk of bias).The Linton procedure is possibly associated with more adverse events than SEPS (RR 0.04, 95% CI 0.00 to 0.60; 1 study; 39 participants); very low-certainty evidence (downgraded three times, twice for very serious imprecision and once for risk of bias).The outcomes time to complete healing, HRQOL, pain, duration of hospitalisation and district nursing care requirements were either not measured, reported or data were not available for analysis.SEPS + saphenous surgery versus saphenous surgery (1 study; 75 participants)It is uncertain whether there is a difference in ulcer healing at 12 months between participants treated with SEPS and saphenous surgery versus those treated with saphenous surgery alone (RR 0.96, 95% CI 0.64 to 1.43; 1 study; 22 participants); very low certainty evidence (downgraded three times, twice for very serious imprecision and once for high risk of reporting bias).It is also uncertain whether there is a difference in the risk of recurrence at 12 months: (RR 1.03, 95% CI 0.15 to 6.91; 1 study; 75 participants); very low certainty evidence (downgraded three times, twice for very serious imprecision and once for high risk of reporting bias).Finally, we are uncertain whether there is an increase in adverse events in the SEPS group (RR 2.05, 95% CI 0.86 to 4.90; 1 study; 75 participants); very low certainty evidence (downgraded three times, twice for very serious imprecision and once for high risk of reporting bias).The outcomes time to complete healing, HRQOL, serious adverse events, pain, duration of hospitalisation, and district nursing care requirements were either not measured, reported or data were not available for analysis. AUTHORS' CONCLUSIONS The role of SEPS for the treatment of venous leg ulcers remains uncertain. Only low or very low-certainty evidence was available for inclusion. Due to small sample sizes and risk of bias in the included studies, we were unable to determine the potential benefits and harms of SEPS for this purpose. Only four studies met our inclusion criteria, three were very small, and one was poorly reported. Further high-quality studies addressing the use of SEPS in venous leg ulcer management are likely to change the conclusions of this review.

Abstract
Cutaneous ulceration from sickle cell disease negatively impacts quality of life. Topical sodium nitrite has previously been shown to reduce the size of sickle leg ulcers. This study examined how topical sodium nitrite impacted the quality of life scores in patients with sickle leg ulcers.We prospectively collected data in patients enrolled in a leg ulcer study (n = 17) or an allogeneic hematopoietic cell transplant study (nonulcer group, n = 15). Both groups completed a pretreatment Short Form-36 questionnaire; the ulcer group completed a second questionnaire after 4 weeks of topical sodium nitrite applications. Data were analyzed by age, sex, >50% area improvement postintervention, and sickle-related complications (vaso-occlusive crises, pulmonary hypertension, or avascular necrosis). Physical and mental component summary scores were analyzed with Student t test.Physical summary scores were lower than mental summary scores in all groups, indicating leg ulcers among other sickle related complications negatively impacted physical quality of life measures. After sodium nitrite use, physical summary scores improved in the leg ulcer group (34.5 ± 9.4 to 39 ± 10.3, P = .03), and mental summary scores improved more in ulcerated patients ≤35 years old (40.7 ± 6.9 to 51.7 ± 9.7, P = .01).Brief topical sodium nitrite has the potential to improve quality of life, especially in younger individuals. Longer treatment duration and randomized-controlled trials are needed to confirm the efficacy of this topical therapy.

Compliance with NICE guidelines when commissioning varicose vein procedures. BJS Open 2018; 2:419-425.

Abstract
Background Varicose veins impair quality of life and can lead to chronic leg ulcers. National Institute for Health and Care Excellence (NICE) guidelines (CG168) set out evidence-based standards for patient management. In England, Clinical Commissioning Groups (CCGs) fund NHS care within their locality. The objective of this study was to evaluate CCGs' commissioning policies and compare them with CG168. Methods Searches were made for the published policies of all 206 English CCGs. They were reviewed for compliance with NICE guidelines and the associated quality standard. Areas of disagreement were analysed for themes. Results Some 203 CCGs (98·5 per cent) had a published policy and 190 (93·6 per cent) of these were published after publication of CG168. Only 73 of the policies (36·0 per cent) were compliant with CG168. Treatment was restricted on the basis of clinical disease severity in 119 CCGs (58·6 per cent); 29 (14·3 per cent) stipulated delay of treatment using a 'trial' of conservative treatment; 22 (10·8 per cent) used lifestyle-related factors such as BMI and smoking status to ration treatment. Treatment was commissioned for uncomplicated symptomatic varicose veins in 87 CCGs (42·9 per cent), but some applied additional rationing mechanisms; 109 CCGs (53·7 per cent) would treat oedema, 183 (90·1 per cent) would treat skin and soft tissue damage, 202 (99·5 per cent) healed ulceration, and all would allow active ulcers to be treated. Discussion The majority of CCGs in England have commissioning policies that contradict NICE guidelines. Rationing strategies include disease severity, delay and patient lifestyle-related factors, creating unwarranted geographical variation for varicose vein treatment, disregarding the NHS Constitution for England, and perhaps leading to an increase in costly treatment of chronic complications in the long term.

Predicting the likelihood of venous leg ulcer recurrence: The diagnostic accuracy of a newly developed risk assessment tool. Int Wound J 2018. [PMID: 29536629 DOI: 10.1111/iwj.12911] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/01/2022] Open
Abstract
The aim of this study was to validate a newly developed tool for predicting the risk of recurrence within 12 months of a venous leg ulcer healing. Performance of the tool to predict recurrence within a 12-month period was assessed using Area Under the Receiver Operating Characteristic Curve (AUC) analysis. Multi-site retrospective and prospective longitudinal studies were undertaken to validate a risk assessment tool for the recurrence of venous leg ulcers within 12 months. In the retrospective study (n = 250), 55% of venous leg ulcers recurred within 12 months, and the risk assessment total score had excellent discrimination and goodness of fit with an AUC of 0.83 (95% CI, 0.76-0.90, P < .001). The prospective study (n = 143) observed that 50.4% (n = 63) of venous leg ulcers recurred within 12 months of healing. Participants were classified using the risk assessment tool as being at low risk (28%), moderate risk (59%), and high risk (13%); the proportion of wounds recurring at 12 months was 15%, 61%, and 67% for each group, respectively. Validation results indicated good discrimination and goodness of fit, with an AUC of 0.73 (95% CI, 0.64-0.82, P < .001). Validation of this risk assessment tool for the recurrence of venous leg ulcers provides clinicians with a resource to identify high-risk patients and to guide decisions on adjunctive, tailored interventions to address the specific risk factors to decrease the risk of recurrence.

Influence of ulceration etiology on the global quality of life and its specific dimensions, including the control of pain, in patients with lower limb vascular insufficiency. Postepy Dermatol Alergol 2018; 34:471-477. [PMID: 29507563 PMCID: PMC5831284 DOI: 10.5114/ada.2017.71116] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Revised: 06/24/2016] [Accepted: 07/20/2016] [Indexed: 11/26/2022] Open
Abstract
Introduction The results of previous studies suggest that the quality of life in patients with lower limb ulcerations is markedly poorer than in the general population – with regard to physical, mental and social spheres. This complex character of that parameter necessitates comprehensive analyses of its specific aspects, including the level of the acceptance of illness and associated pain symptoms. Aim To compare the quality of life and its specific dimensions in patients with lower limb ulcerations of various etiology. Material and methods Patients with the ulcerations resulting from venous (n = 101) or arterial pathologies (n = 98), or having mixed etiology (n = 99) were examined with the: 1) Skindex-29 instrument, 2) Acceptance of Illness Scale, 3) Beliefs about Pain Control Questionnaire, and 4) Coping Strategy Questionnaire. Results The average quality of life related to physical symptoms was significantly higher in patients with venous ulcerations. Patients with ulcerations of arterial etiology more frequently used catastrophizing, and less often ignored pain sensations, used coping self-statements, and increased their activity levels; they were characterized by lower levels of control and poorer ability to decrease the pain. The internal locus of pain control increased proportionally to the global quality of life scores and levels of illness acceptance. Control over pain and ability to decrease the pain were more effective in individuals who used ignoring pain sensations, increasing the activity level, coping self-statements, and reinterpreting pain than in those using catastrophizing or praying and hoping strategies. Conclusions Physical complaints seem to be the basic determinant of the quality of life in patients with the lower limb ulceration, irrespective of its etiology.

Patients' perceptions and experiences of living with a surgical wound healing by secondary intention: A qualitative study. Int J Nurs Stud 2018; 77:29-38. [PMID: 29031127 PMCID: PMC5744862 DOI: 10.1016/j.ijnurstu.2017.09.015] [Citation(s) in RCA: 55] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 08/14/2017] [Accepted: 09/23/2017] [Indexed: 11/17/2022]
Abstract
BACKGROUND Most surgical wounds heal by primary intention, that is to say, the edges of the wound are brought together with sutures, staples, adhesive glue or clips. However, some wounds may be left open to heal (if there is a risk of infection, or if there has been significant tissue loss), and are known as 'surgical wounds healing by secondary intention'. They are estimated to comprise approximately 28% of all surgical wounds and are frequently complex to manage. However, they are under researched and little is known of their impact on patients' lives. OBJECTIVES To explore patients' views and experiences of living with a surgical wound healing by secondary intention. DESIGN A qualitative, descriptive approach. SETTINGS Participants were recruited from acute and community nursing services in two locations in the North of England characterised by high levels of deprivation and diverse populations. PARTICIPANTS Participants were aged 18 years or older and had at least one surgical wound healing by secondary intention, which was slow to heal. Purposeful sampling was used to include patients of different gender, age, wound duration and type of surgery (general, vascular and orthopaedic). Twenty people were interviewed between January and July 2012. METHODS Semi-structured interviews were conducted, guided by use of a topic guide developed with input from patient advisors. Data were thematically analysed using steps integral to the 'Framework' approach to analysis, including familiarisation with data; development of a coding scheme; coding, charting and cross comparison of data; interpretation of identified themes. FINDINGS Alarm, shock and disbelief were frequently expressed initial reactions, particularly to "unexpected" surgical wounds healing by secondary intention. Wound associated factors almost universally had a profound negative impact on daily life, physical and psychosocial functioning, and wellbeing. Feelings of frustration, powerlessness and guilt were common and debilitating. Patients' hopes for healing were often unrealistic, posing challenges for the clinicians caring for them. Participants expressed dissatisfaction with a perceived lack of continuity and consistency of care in relation to wound management. CONCLUSIONS Surgical wounds healing by secondary intention can have a devastating effect on patients, both physical and psychosocial. Repercussions for patients' family members can also be extremely detrimental, including financial pressures. Health care professionals involved in the care of patients with these wounds face multiple, complex challenges, compounded by the limited evidence base regarding cost-effectiveness of different treatment regimens for these types of wounds.

Abstract
AIM To systematically identify, evaluate and synthesize qualitative research that examined the symptoms and health-related quality of life themes that are important from the perspective of patients with venous leg ulceration. BACKGROUND Venous leg ulceration is a common chronic condition; the symptoms and associated treatments have a negative effect on health-related quality of life. Qualitative research methods can provide insight into the personal experiences of patients with venous leg ulceration. DESIGN Qualitative evidence synthesis (using framework synthesis). DATA SOURCES Multiple electronic databases including MEDLINE, EMBASE, PsycINFO and CINAHL were comprehensively searched from inception to November 2015. REVIEW METHODS Systematic identification, quality assessment and synthesis of existing qualitative research were performed; framework synthesis was conducted on included studies. An inductive approach was used and emergent themes were identified. The final stage in the synthesis involved the development of new interpretations. RESULTS Thirteen studies met the inclusion criteria; the overall quality of the included studies was good. Four overarching themes were identified; physical impact, psychological impact, social impact and treatment and, in these, further subthemes were identified. Ulcer and treatment-related pain, as well as odour and exudate appeared to have significant and direct negative effects on quality of life, with additional and cumulative effects on sleep, mobility and mood. CONCLUSION The themes identified in this review should be considered by professionals providing services, care and treatment for venous leg ulcer patients and in the selection, or development, of patient-reported outcome measures for use with this population.

Abstract
Conditions such as diabetes, cardiovascular disease and long-term immobilisation can precipitate the development of chronic dermal ulcers. Such wounds are associated with inflammation and bacterial contamination which in turn can lead to the liberation of offensive odours that cause patient embarrassment and, in some instances, social isolation. Activated carbon-containing dressings have been used to manage the odours from such wounds. However, these can be bulky and can become fouled by wound exudate. Agarose is a natural polysaccharide derived from seaweed that forms brittle free-standing films that can be made pliable by addition of a plasticiser. In this study, activated carbon-containing plasticised agarose films were evaluated for their ability to sequester thiol-containing molecules from solution and the gaseous phase. The water vapour transmission rate was also evaluated to determine the potential breathability of these films should they be considered for application to the skin. It was found that the adsorption of thiols was directly proportional to the activated carbon content of the films. Water vapour was found to pass relatively freely through the films indicating that sweat-induced tissue maceration would be unlikely to occur if applied clinically. In conclusion, activated carbon-containing plasticised agarose films have some potential in the sequestration of malodourous molecules such as those liberated from chronic dermal wounds.

Abstract
CONTEXT Adults with venous leg ulcers frequently experience multiple symptoms that may influence quality of life (QOL). OBJECTIVES The objective of this study was to identify patient subgroups based on their experience with a pain-depression-fatigue-sleep disturbance symptom cluster and to identify differences in patient characteristics and wound-healing and QOL outcomes between the subgroups. METHODS Secondary data analysis from previous longitudinal studies of 247 patients with venous leg ulcers. Latent class analysis identified subgroups of patients with distinct experiences with the symptom cluster of pain, depression, fatigue, and sleep disturbance. Hierarchical regression analysis identified relationships between the subgroups and QOL outcomes. Survival analysis identified differences between the subgroups and ulcer healing. RESULTS Latent class analysis found 67% of patients were in a mild symptom subgroup (i.e., experiencing no or mild pain, depressive symptoms, fatigue, or sleep disturbance). One-third of the samples were in a severe symptom subgroup, who reported moderate-to-severe levels of these symptoms. Compared with the mild subgroup, patients in the severe subgroup had poorer QOL scores (t = 8.06, P < 0.001). Symptom subgroup membership accounted for 19% of the variance (P < 0.001) within a hierarchical regression model that explained 42% of the variance in QOL (F(7,170) = 16.89, P < 0.001, R2 = 0.42). Cox proportional hazards regression found that at enrollment into the study, patients in the severe symptom subgroup were 1.5 times (95% confidence interval 1.02-2.08) less likely to heal in the following 24 weeks (P = 0.037). CONCLUSION Significant relationships were found between delayed ulcer healing, decreased QOL, and membership in the severe symptom subgroup. These findings suggest that comprehensive symptom assessment is needed to identify patients at higher risk for poor outcomes and enable early intervention.

Abstract
We report a 53-year-old female patient presenting with a refractory venous leg ulcer and unremarkable findings in the doppler Ultrasound venous mapping of the leg veins. Further comprehensive diagnostics demonstrated an underlying May-Thurner syndrome. After resolution of the primary mechanical obstruction, rapid wound healing in the following 3 weeks was documented. Iliac vein compression syndrome, commonly known as May-Thurner syndrome, is a distinguishable anatomical variant that results from an external compression over the left iliac vein exerted by the overriding adjacent right common iliac artery. It is mostly seen among young, healthy female patients and can easily be under-diagnosed. Lower extremities duplex ultrasonography remains the gold standard in diagnosing venous insufficiency, but it should not solely depend on it. Instead, clinicians should consider other possibilities, assessing the patency within the truncal veins, which in turn might contribute to the venous insufficiency along the lower limbs. An active early diagnostic approach can prevent significant overall morbidity and help patients to ease back into their daily-life activities. Therefore, it is recommended that all patients with suspected venous insufficiency and normal lower limbs duplex findings should undergo further evaluation of the truncal venous system pattern. May-Thurner syndrome, along with other causes of iliac veins compression, should be considered in the differential diagnosis in unclear persistent cases of unilateral venous symptoms.

Abstract
OBJECTIVE To identify primary empirical research related specifically to feelings of disgust associated with malodorous chronic cutaneous wounds. METHOD A rapid review of the literature using the key words disgust; wounds; malodour and psychosocial. RESULTS A total of 163 papers were retrieved with seven being included for the final review. Themes emanating from the review were malodour, health-care professionals coping with malodour and disgust. Malodour is a concern to patients, which can sometimes go unreported by nursing staff; although the reasons for this remain unclear. The coping mechanisms developed by nurses in response to 'disgusting' wounds requires further exploration in order for a fuller understanding of these mechanisms to be achieved. This review has identified that both health-care professionals and patients can become distressed at wound odours, yet there is little evidence that is available to guide people as to how to manage these feelings. CONCLUSION Hard-to-heal or chronic cutaneous wounds, such as leg ulcers and diabetic foot ulcers, are an increasing global health-care issue. While some research has been undertaken to explore the psychological impact of living with a fungating carcinoma; much less has been written about the management and mitigation of feelings of disgust for patients and families living with a malodorous wound or how health-care professionals can effectively provide psychosocial care.

Abstract
AIMS To identify factors associated with longitudinal changes in health-related quality of life in community-dwelling individuals with venous or mixed-venous leg ulcers. BACKGROUND Most care focuses primarily on healing; this research may additionally lead to strategies to improve quality of life. DESIGN Data from four studies (2000-2009) were combined (2012) to examine quality of life in community-dwelling individuals referred for care of chronic leg wounds. METHODS Data collection occurred at baseline, 3, 6, 9 and 12 months or at healing and included a comprehensive clinical assessment and measures of pain (McGill), functional autonomy (EQ-5D™ ) and quality of life (SF-12TM ). Physical Component Summary and Mental Component Summary scores (SF-12TM ) were categorized by whether or not there was an improvement (≥3 points) over time. Multivariable logistic regression modelling was used to identify factors associated with improvement. RESULTS/FINDINGS Mean age of this sample (n = 519) was 67·5 years, 55·9% were women. Median time to healing was 70 days. Mean Physical Component Summary score increased from 37·0-41·5; factors associated with improvement included independent mobility, family history, problems with usual activities, fewer comorbidities and higher baseline pain. Mean Mental Component Summary score improved from 50·5-53·7; factors associated with improvement included anxiety or depression at baseline and living with others. CONCLUSION Chronic leg ulceration has a substantial, negative impact on health-related quality of life. Ascertaining characteristics associated with changes in quality of life will contribute to the development of comprehensive strategies for prevention, care and improved quality of life.

Abstract
BACKGROUND Venous leg ulcers are common, chronic wounds caused by venous diseases, with a high recurrence rate and heavy disease burden. Compression therapy (bandages or stockings) is the first choice treatment for venous leg ulcers. However, when ulcers remain unhealed, medication can also be used with or without compression therapy. Sulodexide, a highly purified glycosaminoglycan (a naturally occurring molecule) has antithrombotic and profibrinolytic properties (it reduces the formation of blood clots) as well as anti-inflammatory effects. Sulodexide has been studied as a potential treatment for venous leg ulcers. OBJECTIVES To assess the efficacy and safety of sulodexide for treating venous leg ulcers. SEARCH METHODS In July 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; EBSCO CINAHL; Chinese Biomedical Literature Database (CBM); China National Knowledge Infrastructure Database (CNKI); Wan Fang and VIP. We also searched clinical trials registries to identify ongoing studies, as well as references listed in relevant publications. There were no restrictions based on date of publication, language or study setting. SELECTION CRITERIA Randomised controlled trials (RCTs) involving people with a diagnosis of venous leg ulcers which compared sulodexide with placebo or any other drug therapy (such as pentoxifylline, flavonoids, aspirin), with or without compression therapy. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. The authors independently selected studies, extracted data and assessed risk of bias. We pooled data to present the risk ratio (RR) with 95% confidence interval (CI), or presented a narrative summary. We assessed overall evidence quality according to the GRADE approach. MAIN RESULTS We included four RCTs with a total of 463 participants (aged 42 years to 93 years); one report was only available as a published abstract.Meta-analysis of three RCTs suggests an increase in the proportion of ulcers completely healed with sulodexide as an adjuvant to local treatment (including wound care and compression therapy) compared with local treatment alone (rate of complete healing with sulodexide 49.4% compared with 29.8% with local treatment alone; RR 1.66; 95% CI 1.30 to 2.12). This evidence for sulodexide increasing the rate of complete healing is low quality due to risk of bias. It is unclear whether sulodexide is associated with any increase in adverse events (4.4% with sulodexide versus 3.1% with no sulodexide; RR 1.44; 95% CI 0.48 to 4.34). The evidence for adverse events is very low quality, downgraded twice for risk of bias and once for imprecision. AUTHORS' CONCLUSIONS Sulodexide may increase the healing of venous ulcers, when used alongside local wound care, however the evidence is only low quality and the conclusion is likely to be affected by new research. It is not clear whether sulodexide is associated with adverse effects. The standard dosage, route and frequency of sulodexide reported in the trials was unclear. Further rigorous, adequately powered RCTs examining the effects of sulodexide on healing, ulcer recurrence, quality of life and costs are necessary.

Correlation between health-related quality of life and venous leg ulcer's severity and characteristics: a cross-sectional study. Int Wound J 2016; 14:360-368. [PMID: 27112627 DOI: 10.1111/iwj.12610] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2015] [Revised: 04/05/2016] [Accepted: 04/06/2016] [Indexed: 10/21/2022] Open
Abstract
This study aims to determine health-related quality of life (HRQoL) in patients suffering with venous ulceration and to correlate wound's severity status with HRQoL loss as well as identify the aspects of HRQoL most negatively affected by the presence of venous ulcers. In this observational, cross-sectional, descriptive, analytical multi-centre study, data was compiled over a period of 3·5 months. Thrity-four patients with venous ulceration were recruited. The RESVECH 2·0 scale was used to monitor wounds. The MAID scale was used to measure wound's severity. The Charing Cross Venous Ulcer Questionnaire (CCVUQe) (Spanish version) was used to evaluate quality of life. The mean CCVUQe score was 60·58 ± 16·04. The HRQoL dimension most affected was 'Emotional state' (mean score = 77. 67 ± 17·34). The average RESVECH 2.0 score for the wounds was 13·15 ± 5·07. A statistically significant association between total CCVUQ-e score and total RESVECH 2.0 score was detected [Pearson correlation coefficient r = 0·546 (P ≤ 0·001)]. Venous ulcers affect patients' HRQoL, particularly their emotional status. There is a relationship between the severity of the wound and loss of HRQoL. The presence of non-viable tissue, poor exudate control and infection all determine loss of HRQoL. New studies are needed to confirm these findings.

Abstract
An evaluation of a new short-stretch compression system (CoFlex UBZ, TLC and TLC Lite, Aspen Medical Europe Ltd) was undertaken in four leg ulcer clinics. A total of 19 patients aged 42-93 years were treated for up to 4 weeks, or until healed. Collated data included age, underlying diseases, leg ulcer type, ulcer duration and current treatment. The evaluation included quality of life measurements, wear time, slippage, exudate strikethrough and pain using a numerical pain score. Patients were asked to document sleep patterns. Compression was applied according to clinical need. Inclusion criteria were non-healing wounds on the lower limb existing for more than 6 weeks that were suitable for compression. Exclusion criteria included patients with untreated peripheral disease, ankle-brachial pressure index (ABPI)<0.5 or those unable to consent. Staff were asked to rate performance, wear time, fluid handling and conformability. Wound tissue types improved significantly for n=16 (84%) patients. Pain scores reduced significantly by week 2, n=11 (58%) patient leg ulcers had improved, n=2 (11%) patients in standard compression noted a marked reduction in malodour and sloughy tissue. n=16 (84%) rated the overall performance as 'very good' or 'good'. A detailed cost analysis was undertaken on one patient, suggesting a potential cost saving of £186.92 per month and a cost efficiency saving of 43.4%.

A Multicenter Randomized Controlled Trial Comparing Treatment of Venous Leg Ulcers Using Mechanically Versus Electrically Powered Negative Pressure Wound Therapy. Adv Wound Care (New Rochelle) 2015; 4:75-82. [PMID: 25713749 DOI: 10.1089/wound.2014.0575] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2014] [Accepted: 09/01/2014] [Indexed: 11/12/2022] Open
Abstract
Objective: This study compares two different negative pressure wound therapy (NPWT) modalities in the treatment of venous leg ulcers (VLUs), the ultraportable mechanically powered (MP) Smart Negative Pressure (SNaP®) Wound Care System to the electrically powered (EP) Vacuum-Assisted Closure (V.A.C.®) System. Approach: Patients with VLUs from 13 centers participated in this prospective randomized controlled trial. Each subject was randomly assigned to treatment with either MP NPWT or EP NPWT and evaluated for 16 weeks or complete wound closure. Results: Forty patients (n=19 MP NPWT and n=21 EP NPWT) completed the study. Primary endpoint analysis of wound size reduction found wounds in the MP NPWT group had significantly greater wound size reduction than those in the EP NPWT group at 4, 8, 12, and 16 weeks (p-value=0.0039, 0.0086, 0.0002, and 0.0005, respectively). Kaplan-Meier analyses showed greater acceleration in complete wound closure in the MP NPWT group. At 30 days, 50% wound closure was achieved in 52.6% (10/19) of patients treated with MP NPWT and 23.8% (5/21) of patients treated with EP NPWT. At 90 days, complete wound closure was achieved in 57.9% (11/19) of patients treated with MP NPWT and 38.15% (8/21) of patients treated with EP NPWT. Innovation: These data support the use of MP-NPWT for the treatment of VLUs. Conclusions: In this group of venous ulcers, wounds treated with MP NPWT demonstrated greater improvement and a higher likelihood of complete wound closure than those treated with EP NPWT.

Abstract
BACKGROUND Well-tolerated and effective treatments are needed for chronic leg ulcers in sickle cell anaemia. Topical sodium nitrite, a known nitric oxide donor, enhances blood flow in ulcers and has known bacteriostatic effects. We aimed to assess the safety, tolerability, and pharmacokinetics of topical sodium nitrite in patients with sickle cell disease and chronic leg ulcers. METHODS We enrolled adult patients from an ambulatory clinic at the National Institutes of Health (Bethesda, MD, USA) with sickle cell anaemia with leg ulcers (with a surface area of 2.5-100 cm2) persisting for at least 4 weeks into a safety and tolerability phase 1 dose-escalation trial of topical sodium nitrite. Increasing concentrations of sodium nitrite cream were applied twice weekly for 4 weeks to one ulcer per patient at five dose levels (0.5%, 1%, 1.5%, 1.8%, and 2%). The primary endpoints were safety and tolerability, with secondary endpoints of pharmacokinetics, blood flow, and wound healing. Pain relief was analysed post hoc. Endpoints were analysed over time for the whole study population and according to dose level. This study is registered with ClinicalTrials.gov, number NCT01316796. FINDINGS Between April 4, 2011, and March 19, 2013, we enrolled 18 adult patients with sickle cell anaemia and leg ulcers into our trial. We assigned three patients into each cohort, and each cohort was treated with a different concentration of sodium nitrite cream (cohort 1: 0.5%, cohort 2: 1.0%, cohort 3: 1.5%, and cohort 4: 2.0%). Patients were not enrolled into the next cohort dose until we were able to establish that no dose-limiting toxicities were observed. An additional six patients were enrolled to cohort 3a: 1.8%, after two patients in cohort 4 had asymptomatic drops in diastolic blood pressure. No grade 3-4 adverse events were observed, and there were no serious adverse events or dose-limiting side-effects. Pharmacokinetic analysis showed that systemic absorption of sodium nitrite was very low. Application of topical sodium nitrite was associated with a significant increase in peri-wound cutaneous blood flow measured by laser speckle contrast imaging (p=0.0002), corroborated by increased peri-wound skin temperature by infrared thermography (p=0.0119). We recorded a dose-dependent decrease in leg ulcer size (p=0.0012) and pain (p<0.0001). Ulcers healed completely in three patients who received the highest concentrations of topical sodium nitrite (the 1.8% and 2% cream). In our post-hoc analysis of pain, brief pain inventory scores improved in pain severity (p=0.0048) and pain interference (p=0.0013). INTERPRETATION Our results indicate that topical sodium nitrite 2% cream is suitable for additional clinical trials in adults with sickle cell anaemia to promote healing of leg ulcers.

Abstract
OBJECTIVE To explore the psychological treatment options for pruritus in patients with wounds. METHOD This study employed a narrative design with a search being completed using the databases Academic Search Complete, Google Scholar, PsycInfo, PsycARTICLES, Medline and CINAHL Plus. All articles between 1980-2013 that included the following search terms: [pruritus OR itch OR itching] AND [management OR psychological interventions OR treatment] AND [wounds OR burns OR wounds burns] were included in the review. RESULTS A number of psychological treatments options emerged from the literature search that were suggested to be effective for treating itching. These included methods such as habit reversal, suggestions, relaxation, massage and itch-coping programmes. Each of these methods showed potential for improving the patient experience by reducing itching, although the research evidence is currently somewhat limited. CONCLUSION Although itching is a common symptom in wounds, the use of psychological treatments for this may be rather limited. The treatments discussed show promise and their use should be a welcome addition to the healthcare professional's armoury for working with people with wounds. DECLARATION OF INTEREST There were no external sources of funding for this study. The authors have no conflicts of interest to declare.

A prospective, open, multicentre study to evaluate a new gelling fibre dressing containing silver in the management of venous leg ulcers. Int Wound J 2014; 11:438-45. [PMID: 24602074 PMCID: PMC4674970 DOI: 10.1111/iwj.12239] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2013] [Revised: 01/16/2014] [Accepted: 01/20/2014] [Indexed: 12/01/2022] Open
Abstract
This study investigated the performance of a new gelling fibre dressing containing silver (DURAFIBER™ Ag; Smith & Nephew, Hull, UK) in moderate to highly exuding venous leg ulcers with one or more clinical signs of infection. Fourteen patients with venous leg ulceration of median ulcer duration 12·5 weeks, recruited from three centres in South Africa, received treatment with the new dressing for a maximum of 8 weeks. Multilayer compression bandaging was used for all patients, at the majority of assessments. The objectives of this study were to assess the clinical acceptability of the dressing in terms of the following characteristics: antimicrobial properties, the progress of the wound towards healing, wear time, exudate management, conformability, patient comfort, pain on application, pain on removal and dressing integrity. The new dressing was rated as clinically acceptable for all characteristics, for all 14 patients (100%). It was easy to apply and remove; in 96·8% of removals, the dressing stayed intact on removal and could be removed in one piece. Fifty per cent of the wounds healed within the 8-week study duration; between baseline and final assessment, the median percentage reduction in wound area was 98·2% and the median percentage reduction in devitalised tissue was 78%. Exudate levels and wound pain were significantly improved at final assessment compared to baseline assessment, and an increase in the number of patients with healthy peri-wound skin between baseline and final assessment was observed. A reduction in bioburden and signs of clinical infection and an improvement in quality of life were observed over the 8-week period. The average wear time was 6·4 days. This study supports the use of new dressing in the management of moderately to highly exuding venous leg ulcers with clinical signs of infection.

Abstract
CONTEXT Patients with venous leg ulcers experience multiple symptoms, including pain, depression, and discomfort from lower leg inflammation and wound exudate. Some of these symptoms impair wound healing and decrease quality of life (QOL). The presence of co-occurring symptoms may have a negative effect on these outcomes. The identification of symptom clusters could potentially lead to improvements in symptom management and QOL. OBJECTIVES To identify the prevalence and severity of common symptoms and the occurrence of symptom clusters in patients with venous leg ulcers. METHODS For this secondary analysis, data on sociodemographic characteristics, medical history, venous history, ulcer and lower limb clinical characteristics, symptoms, treatments, healing, and QOL were analyzed from a sample of 318 patients with venous leg ulcers who were recruited from hospital outpatient and community nursing clinics for leg ulcers. Exploratory factor analysis was used to identify symptom clusters. RESULTS Almost two-thirds (64%) of the patients experienced four or more concurrent symptoms. The most frequent symptoms were sleep disturbance (80%), pain (74%), and lower limb swelling (67%). Sixty percent of patients reported three or more symptoms at a moderate-to-severe level of intensity (e.g., 78% reported disturbed sleep frequently or always; the mean pain severity score was 49 of 100, SD 26.5). Exploratory factor analysis identified two symptom clusters: pain, depression, sleep disturbance, and fatigue; and swelling, inflammation, exudate, and fatigue. CONCLUSION Two symptom clusters were identified in this sample of patients with venous leg ulcers. Further research is needed to verify these symptom clusters and to evaluate their effect on patient outcomes.

Abstract
Part 1 of the KTwo evidence review concerned the efficacy and reproducibility of the bandage system in the management of leg ulceration and lymphoedema. Here, in Part 2, the focus shifts to its tolerability and acceptability to both patients and clinicians. The evidence presented here ranges from a randomised controlled trial to anecdotal reports in conference posters. The aim of this review is to describe the evidence, and not to critique it.
