Factors associated with physical activity levels in people with venous leg ulcers: A multicentre, prospective, cohort study

Association between physical activity levels and healing in people with venous leg ulcers: secondary analysis of prospective cohort data

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.

The Effect of an Educational Intervention on Self-Care in Patients with Venous Leg Ulcers-A Randomized Controlled Trial

Background: Although patients with venous leg ulcers are involved in ulcer management, little is known about why and how these patients self-treat their ulcers without direct supervision by health professionals. Yet patients’ knowledge of ulcer management can be important for achieving ulcer closure and/or preventing recurrence. This study thus investigates the effects of an educational intervention on knowledge of self-care among patients with venous leg ulcers, mainly on wound dressing practice, compression therapy, physical activity and nutrition. Methods and participants: This research was conducted in three outpatient hospitals in central Croatia. An educational brochure was made and distributed to patients; patients were surveyed about caring for venous leg ulcers before the brochure was distributed and after 3 months. Results: In total, 208 patients were involved in the study: 112 in the experimental group and 96 in the control group. The educational intervention increased awareness of compression therapy, knowledge of recurrence prevention, appropriate lifestyle habits, and warning signs related to venous leg ulcers. Conclusions: Patient education on illness and self-care is necessary to achieve positive effects in self-care knowledge. In this study, patients learned how to change dressings, learned how to improve their lifestyle, and were empowered to deal with their illness.

Physical Activity as an Adjunct to Compression Therapy on Healing Outcomes and Recurrence in Patients With Venous Leg Ulcers: A Scoping Review Protocol

Background: Chronic venous leg ulceration is a common and costly clinical issue across the world, affecting up to 3 in 1,000 people. Compression therapy is recommended as the gold standard treatment in clinical practice, although a large number of venous leg ulcers remain unhealed after several years. Physical activity may improve healing although there is limited evidence on the effects of physical activity as an adjuvant treatment to compression to improve venous leg ulcers healing and prevent recurrence. Objectives: This scoping review protocol aims to systematically search, appraise, and synthesize quantitative research evidence to assess the effect of physical activity interventions applied in conjunction with compression therapy on venous leg ulcer healing and recurrence. Methods and Analysis: We will use the methodology framework suggested by Arksey and O'Malley, Levac et al., the JBI as a guide. We will also follow the three-step search strategy recommended by the JBI to systematic search for relevant published research, ongoing clinical trials, and grey literature. Two review authors will independently screen titles and abstracts followed by full-text review to determine final eligibility for inclusion. The search process will be reported using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow chart. Characteristics of physical activity interventions, primary outcomes related to ulcer healing and recurrence, and secondary outcomes of interest included quality of life, pain level, adverse effects, and economic costs will be extracted and summarized. The review will provide a descriptive account of the findings from included studies. Where appropriate, data will be pooled for a meta-analysis using a random effects model. Discussion: Physical activity interventions represent a low-cost, potentially useful adjuvant treatment to compression therapy for the management of venous leg ulcers. Several gaps in knowledge remain that are answerable via a targeted scoping review. This protocol outlines the rationale, objectives, and the planned methodology for conducting the study. Ethics and Dissemination: The scoping review will use data from publicly available sources and ethical approval is not required. Findings from this review will be submitted to a peer-reviewed journal, presented at relevant conferences and disseminated via social media.

A conceptual framework of patient-reported outcomes in people with venous leg ulcers

Venous leg ulcers (VLUs) are a common chronic often undertreated condition, which affects individual's health-related quality of life (HRQoL). Numerous patient-reported outcome measures (PROMs) have been validated to capture HRQoL in patients with VLUs. However, available instruments contain many items, are hard to use in clinical practice, and present with weak responsiveness. This study aims to determine clinical utility of an existing VLU-QoL instrument and to develop a comprehensive PROs assessment framework to guide clinical practice treatment in people with VLUs in Australia. Semi-structured qualitative interviews were conducted with VLU patients (N = 13) and their managing clinicians (N = 6) in Victoria, Australia. Interview topics covered content and face validity, appropriateness, and acceptability of the VLU-QoL instrument to determine suitable and appropriate for use in clinical practice. Clinicians and patients agreed that a VLU-QoL instrument was needed in clinical practice. Both clinicians and patients agreed it would be appropriate to answer PROMs questions prior to consultation with clinicians every 3-6 months. However, patients considered that some of the questions are ambiguous and too technical. Patients reported that it would be useful to include additional items relating to daily wound care, compression bandaging, and dressings. Clinicians reported that the VLU-QoL instrument was too long and required restructuring to facilitate utility in practice. A conceptual framework for HRQoL in VLUs included traditional HRQoL components and VLU-specific issues. Overall, the VLU-QoL was well accepted, although changes to make it more concise, comprehensive, and to clearly reflect consumers' perspectives were lacking. The proposed conceptual framework will inform the development of a new PROM for use by clinicians and patients in clinical settings.

A scoping review on Chronic Venous Disease and the development of a Venous Leg Ulcer: The role of obesity and mobility

OBJECTIVE

The risk factors obesity and reduced mobility are not well known in the development of a Venous Leg Ulcer (VLU). The aim of this scoping review is to explore the mechanisms by which obesity and reduced mobility contribute the development of a VLU in patients with Chronic Venous Disease (CVD).

METHODS

For this scoping review a search was performed in May 2019 in the Cochrane Library and Pubmed to identify studies on the working mechanisms of obesity and mobility in developing a VLU. Hand searches were performed to find additional studies explaining the working mechanisms (indirectly related to the VLU). Two reviewers independently reviewed the abstracts and full-text articles.

RESULTS

Twenty-eight studies met our eligibility criteria. Disturbed range of ankle motion and gait can lead to a reduced Calf Muscle Pump (CMP) function which leading to a venous outflow disorder. Increased abdominal pressure due to obesity can lead to a venous outflow obstruction and increased adipose tissue mass results in an increase in adipokine secretion. The venous outflow disorder, outflow obstruction and increased adipokine secretion can all lead to chronic systemic inflammation, increased endothelial permeability and hence microcirculatory dysfunction. This alone can result in a VLU.

CONCLUSION

Obesity and reduced mobility can lead to a reduction of the CMP function, an increase in abdominal pressure and an increase in adipose tissue mass. This can simultaneously lead to haemodynamic changes in the macro- and microcirculation of the lower extremities and eventually in a VLU. In patients with obesity and reduced mobility the microcirculation alone can lead to skin changes and eventually a VLU. Therefore, early recognition of CVD symptoms in patients with obesity and reduced mobility is crucial to diagnose and treat CVD to prevent a VLU.

Adjuvant therapies in venous leg ulcer management: A scoping review

Compression therapy is the current evidence-based approach to manage venous leg ulcers (VLU); however, adherence is a major barrier to successful treatment. Combination approaches may relieve the burden of treatment by shortening the time to ulcer healing. This scoping review conducted by Australian researchers aimed to establish the evidence of effectiveness of various adjuvant methods on wound healing and recurrence. Randomized Controlled Trials (RCTs), and Systematic Reviews (SR) and Meta-Analyses (MA) on VLU management approaches published from January 2015 to December 2018 were included in this review. The articles included in the scoping review were grouped according to the management approaches, including (1) pharmaceutical interventions, (2) surgical interventions, (3) topical agents, (4) the use of devices, and (5) other, such as physiotherapy and psychological interventions. Results of this scoping review indicate that there is a limited high-quality evidence of effectiveness in most adjuvant therapies on wound healing and recurrence. Given the low-quality evidence observed in this scoping review for adjuvant treatments, the implication for practice is that current management guidelines be followed. Further rigorous studies have the potential to produce better quality evidence. Quality of evidence can be improved by ensuring large sample sizes of a single etiology wounds, standardizing reporting outcomes, and maintaining detailed and evidence-based protocols in physiological or psychological interventions.

Factors associated with physical activity levels in people with venous leg ulcers: A multicentre, prospective, cohort study

Increasing levels of physical activity among people with venous leg ulcers (VLUs) can potentially reduce the health cost burden, improve functional aspects of patients' lives and increase ulcer healing rates. The aim of this study was to investigate factors associated with physical activity levels in patients with VLUs. Data from 2016 to 2017 Aspirin for Venous Leg Ulcer cohort study were analysed for the present study. Ninety participants were recruited from 5 outpatient specialist wound clinics across Victoria, Australia between August 2016 and April 2017. There was a statistically significant association between diabetes and physical activity, with a higher proportion of people with type 2 diabetes in the sedentary category. Further, there was a statistically significant association between patient-reported VLU education and physical activity levels. An indirect advantage of relevant, easy-to-understand education about VLUs may increase physical activity levels, which may facilitate improved time to healing of VLUs.
