A review of the factors influencing nonrecurrence of venous leg ulcers

Traffic light system for healed venous leg ulcer monitoring

The purpose of this paper is to introduce the conceptualisation and evolution of a trialed Doppler traffic light system for healed venous leg ulceration. This tool aims to facilitate clinical decision-making and provides a systematic approach to the ongoing assessment of arterial disease in patients with healed venous leg ulcers when used in conjunction with other purposely-designed assessment documentation to ensure the novice registered and unregistered nurse contributes safely and effectively to the care of patients. The validation and trial of this clinical decision tool is discussed in terms of the use of a recognised methodology determining its fitness for purpose and robustness.

Managing a venous leg ulcer in the 21st century, by improving self-care

This paper examines the context of managing a long-term condition within the community environment using appropriate evidence-based literature. It is a case study that focuses upon concordance with compression bandaging in treating venous leg ulceration and preventing ulcer recurrence through a well leg clinic. The challenges of this episode of care and the interventions put in place to improve concordance and promote self-care will be explained and analysed.

Relationships between preventive activities, psychosocial factors and recurrence of venous leg ulcers: a prospective study

AIM

The aim of this study was to identify relationships between preventive activities, psychosocial factors and leg ulcer recurrence in patients with chronic venous leg ulcers.

BACKGROUND

Chronic venous leg ulcers are slow to heal and frequently recur, resulting in years of suffering and intensive use of healthcare resources.

METHODS

A prospective longitudinal study was undertaken with a sample of 80 patients with a venous leg ulcer recruited when their ulcer healed. Data were collected from 2006 to 2009 from medical records on demographics, medical history and ulcer history; and from self-report questionnaires on physical activity, nutrition, preventive activities and psychosocial measures. Follow-up data were collected via questionnaires every 3 months for 12 months after healing. Median time to recurrence was calculated using the Kaplan-Meier method. A Cox proportional-hazards regression model was used to adjust for potential confounders and determine effects of preventive strategies and psychosocial factors on recurrence.

RESULTS

There were 35 recurrences in a sample of 80 participants. Median time to recurrence was 27 weeks. After adjustment for potential confounders, a Cox proportional hazards regression model found that at least an hour/day of leg elevation, 6 or more days/week in Class 2 (20-25 mmHg) or 3 (30-40 mmHg) compression hosiery, higher social support scale scores and higher General Self-Efficacy scores remained significantly associated (P < 0·05) with a lower risk of recurrence, while male gender and a history of deep vein thrombosis remained statistically significant risk factors for recurrence.

CONCLUSION

Results indicate that leg elevation, compression hosiery, high levels of self-efficacy and strong social support will help prevent recurrence.

Advancing nursing documentation--an intervention study using patients with leg ulcer as an example

AIM

The aim was to implement and evaluate a standardised nursing record, using patients with leg ulcer as an example, regarding the content of the nursing record and district nurses' experiences of documentation.

METHOD

This was a prospective, stratified and randomised intervention study, with one intervention group and one control group. A standardised nursing wound care record was designed and implemented in the electronic patient record in the intervention group for a period of 3 months. Pre- and post-intervention audits of nursing records [n=102 and n=92, respectively] were carried out and 126 district nurses answered questionnaires pre-intervention and 83 post-intervention.

RESULT

The standardised nursing wound care record led to more informative, comprehensive and knowledge-intensive documentation according to the audit and district nurses' opinions. Furthermore, the district nurses' self-reported knowledge of nursing documentation increased in the intervention group. When the standardised nursing wound care record was not used, the documentation was mostly incomplete with a lack of nursing relevance. There were no differences in the district nurses' experiences of documentation in general between the two groups.

CONCLUSION

Using the standardised nursing wound care record improved nursing documentation meeting legal demands, which should increase the safety of patient. There was however a discrepancy between the nurses stated knowledge and how they carried out the documentation. Regular in-service training together with use of evidence based standardised nursing records, as a link to clinical reasoning about nursing care, could be ways effecting change.

Developing a nurse-led education program to enhance self-care agency in leg ulcer patients

Patients with leg ulceration face changing self-care demands associated with the consequences of the disease and treatment. Often patients can manage their self-care for some time, but new therapeutic self-care demands may emerge that require more complex self-care actions. The purpose of this article is to describe the development of a nurse-led education program in North-Rhine Westphalia, Germany, that aims to help patients with leg ulcers to meet their therapeutic self-care demands. Orem's self-care deficit nursing theory is used as a framework to provide the conceptual context for this supportive-educative nursing system that is being tested in a multi-site clinical trial.

Interventions to enhance patient compliance with leg ulcer treatment: a review of the literature

BACKGROUND AND AIMS

Non-compliance with compression therapy and with leg exercises and leg elevation is a common problem, often reported in patients with venous leg ulceration. Studies on compliance-enhancing interventions and the effectiveness of these interventions in patients with venous leg ulceration were reviewed.

METHODS

MEDLINE, Cochrane, Embase and CINAHL were explored up to April 2005. Reference lists, wound care journals and conference proceedings were searched. Experts and manufacturers of compression systems were contacted. Studies were eligible if they included patients with venous or mixed leg ulcers and reported patient compliance outcome. Twenty studies were included.

RESULTS

Most studies describe patient compliance as the extent to which the compression system was worn and/or the extent to which treatment regimen was followed. Self-reporting was the most commonly used method of compliance assessment. There are indications that class III stockings for patients with venous ulcers enhance compliance compared with short stretch compression bandages. No real evidence is found that intermittent pneumatic compression systems improved compliance. There is no well-documented evidence that healthcare system interventions increase compliance. Educational programmes combining cognitive, behavioural and affective components were shown to have a positive effect on leg elevation, but not on compliance with compression therapy.

CONCLUSION

The included studies have a lack of consistency in defining the standard and operationalization of compliance. Patient compliance plays an ancillary role in research. No study has been able to offer an acceptable and well-documented solution to the non-compliance problem.

RELEVANCE TO CLINICAL PRACTICE

Research might focus on the development of comprehensive compliance-enhancing strategies. A stronger commitment of healthcare providers and society is needed to make progress in this area. The scope of nursing must be expanded to also include the problems experienced by patients with leg ulcers and the improvement of patient compliance.

Preventing venous ulcer recurrence: a review

This review article examines the available evidence on both the primary and secondary prevention of venous ulceration, exploring both the individual, social and financial implications of system failures that allow patients to remain at increased risk of recurrent ulceration. The role of both venous disease assessment and corrective superficial venous surgery are discussed in the light of recently published randomised controlled studies on the role of superficial venous surgery as both an adjunct to ulcer healing and ulcer prevention.

Setting up a community nurse-led healed leg ulcer clinic

Chronic obstructive pulmonary disease (COPD) is a progressive, smoking-related, chronic disease that eventually impacts on every area of the lives of the patient and his/her family and carers. The nature of the disease - chronic, irreversible airflow obstruction - limits the impact of drug therapy, particularly as the disease progresses. Increasing breathlessness on exertion saps confidence, reduces self-esteem and produces dependence. In addition, frequent exacerbations utilize health service resources. Non-pharmacological approaches, such as pulmonary rehabilitation, together with lifestyle advice that enables patients to help themselves manage exacerbations, maintain independence and quality of life and make the most of life with COPD can benefit both patients and the health service.

Acti-Glide: a simple method of applying compression hosiery

Compression hosiery is often worn to help prevent aching legs and swollen ankles, to prevent ulceration, to treat venous ulceration or to treat varicose veins. However, patients and nurses may experience problems applying hosiery and this can lead to non-concordance in patients and possibly reluctance from nurses to use compression hosiery. A simple solution to applying firm hosiery is Acti-Glide from Activa Healthcare.

Exploring debridement options for chronic venous leg ulcers

The presence of devitalized tissue in a wound is a common problem facing practitioners and is regarded by many as a major inhibitory factor in the wound-healing process and can act as a focus for microbial proliferation. Therefore, for wound healing to proceed in a logical and ordered fashion, it follows that any necrotic material should be cleared from the wound bed. Wound bed preparation is now recognized as crucial to facilitating ordered restoration and regeneration of damaged tissue. However, there is a clear lack of good clinical evidence to support available wound debridement options, particularly for chronic ulcers of the lower extremities. This article reviews the debridement options available to practitioners and discusses rationales for treatment and implications for clinical practice with specific reference to chronic venous leg ulcer management.

Factors influencing concordance with compression stockings after venous leg ulcer healing

OBJECTIVE

To investigate the factors influencing patient concordance with compression stockings after venous leg ulcer healing.

METHOD

In 2001 patients discharged from a specialist leg ulcer service in New Zealand were approached to participate in a structured interview about their use of compression stockings in the first six months following venous leg ulcer healing. Univariate analyses were performed to identify significant associations between factors and stocking use. Multiple logistic regression was employed to model the factors associated with frequency of stocking use.

RESULTS

A total of 163 patients were identified, of whom 129 (79%) agreed to participate. Sixty-seven (52%) reported wearing stockings every day for the first six months after their ulcers had healed, 21 (16%) stated that they had worn the most days, seven (5%) had worn them occasionally and 29 (22%) had not worn them at all after their ulcer had healed. Five (4%) did not provide data. Two factors distinguished those who wore stockings from those who did not 75% of the time: the belief that wearing stockings was worthwhile and the belief that stockings were uncomfortable to wear. Commonly cited factors, such as age, sex, difficulty in applying stockings and cosmetic appearance were not significantly related to stocking use. Cost did not seem to influence the decision to purchase compression stockings.

CONCLUSION

Many factors previously thought to influence concordance appear to have little impact on compression-stocking use in people whose venous leg ulcers had healed.

Nurse-led education sets out to improve patient concordance and prevent recurrence of leg ulcers

OBJECTIVE

This study evaluated the effects of a structured nurse-led education programme that aimed to improve patient concordance and prevent venous leg ulcer recurrence.

METHOD

The design was quasi-experimental. Subjects (average age: 80) had venous leg ulceration that had healed within the previous two years, and were cared for at home by a district nurse. Data were available on 49 patients with 97 legs, 72 of which had had venous leg ulcers. Patients were divided into two groups: a control group, which received 'usual' care, and experimental group, which was exposed to the education programme. Recurrence rates, the effects of the education on patient behaviour and the effect on recurrence of having both ankle movement and general mobility were measured over one year.

RESULTS

Patients in the experimental group experienced significantly less recurrence over the year (log rank test = 8.28, p = 0.004). To control for differences in mobility and ankle movement in the control and experimental groups at baseline, simultaneous logistic regression analysis was undertaken. This revealed a significant advantage for patients in the experimental group (p = 0.035; OR = 4.45, 95% CI = 1.11-17.74), who spent more time with their legs elevated each day. This difference was sustained throughout the 52 weeks (f = 2.88, p = 0.015). Those who had both full ankle movement (> 60 degrees) and full mobility (without aid) had significantly less recurrence (p = 0.042). Education had no significant effect on the amount of time patients wore compression hosiery (f = 2.1).

CONCLUSION

A structured nurse-led patient concordance programme is effective in preventing venous leg ulcer recurrence and increasing the time patients spend with their legs elevated at heart level. Having both full ankle movement and full mobility reduces the risk of recurrence.

An evaluation of the leg and foot ulcer treatment provided in Oslo

OBJECTIVE

This study set out to gather more information about the treatment of leg and foot ulcers in the community in Oslo, Norway.

METHOD

A structured questionnaire on leg and foot ulcer treatment was sent to 173 community nurses in Oslo, of whom 102 responded with data on 145 patients.

RESULTS

Of the sample, 55.9% had leg ulcers, 32.2% had foot ulcers and 11.9% both; 26.2% had diabetes. Thirty-four per cent of the patients had not had a diagnosis of leg ulceration. Saline was the preferred cleansing solution. Compression therapy was used on all types of ulcer. Pain was a problem for 52.9% of the patients, of whom 9% did not receive analgesia.

CONCLUSION

Nurses and doctors working in this community need to update their knowledge of wound treatments.

Errors and discrepancies: a patient perspective on leg ulcer treatment at home

OBJECTIVE

This Norwegian study explored the treatment experiences of nine patients with a leg ulcer who lived at home.

METHOD

The study was descriptive and exploratory, with open-ended interviews. Five women and four men aged 60-96 years who had a leg ulcer for more than six weeks participated. Most had a venous/arterial leg ulcer, lasting from between four months to 'my whole adult life'.

RESULTS

Treatment was not always carried out in a correct and caring manner. The patients experienced trial and error in their treatment, delays in the arrival of the helpers, unhygienic methods and lack of information about the cause and treatment of their ulcer. Despite these problems, they had confidence in the treatment they received.

CONCLUSION

The treatment, hygiene and organisation of the care of patients with leg ulcers living at home needs improving.

Living with a chronic leg ulcer: an insight into patients' experiences and feelings

OBJECTIVES

This study sought to ascertain patient need and help health-care professionals to understand the effects of chronic leg ulceration from a patient's perspective.

METHOD

A qualitative grounded theory approach was used. A purposeful sample of eight participants (six females and two males) was selected. All were under the care of a district nurse and had over a year's history of venous leg ulceration. Data were collected by interview.

RESULTS

Five major categories developed, relating to the 'physical experience', 'loss of control', 'vision of the future', 'carer's perspective' and 'health-care professional and patient relationship'.

CONCLUSION

Although the physical and psychological effects of leg ulceration featured prominently in this study, these were heavily influenced by the relationship between the participant and the health-care professional.

Community nurses', home carers' and patients' perceptions of factors affecting venous leg ulcer recurrence and management of services

AIM

This study examines the feasibility of utilizing social service home carers (SSHC) to provide a collaborative approach with community nurses for the provision of leg ulcer aftercare in four National Health Service (NHS) Trusts. The purpose of this study was to gain insight into what community nurses and people with healed venous leg ulcers felt influenced leg ulcer recurrence.

BACKGROUND

Studies have demonstrated that provision of community-based leg ulcer clinics has improved healing rates of venous leg ulcers, yet recurrence remains a problem. The reasons for this are far from clear, and further research is required before unequivocal support can be given to one approach to the provision of care for this client group. Collaborative approaches to the provision of leg ulcer aftercare are beginning to receive more attention. It has been recognized that social service health carers could be co-opted to provide essential aftercare once healing has occurred, although the logistics of this approach have not been fully explored.

METHODS

This study was conducted in four NHS Trusts. Stage one used focus groups to explore the perceptions of district nurses (n = 15) and social service health carers (n = 15) of a leg ulcer shared care project and to gain insight into factors that they felt influenced recurrence. The second stage used semistructured interviews (n = 12) to explore the perceptions that people with healed leg ulcers have about factors influencing ulcer recurrence.

FINDINGS

Key themes emerging from this study were: health promotion is perceived by community nurses and patients to be ineffective and leg ulcer aftercare services are fragmented. Organizational factors such as time constraints and limited resources were cited by community nurses and home carers as being responsible for high leg ulcer recurrence rates. Community nurses expressed a desire to delegate preventative aspects of leg ulcer care to home carers rather than participate in health promotion strategies to support healing behaviours.

CONCLUSIONS

A strategy aimed at supporting healing behaviour in elderly people has the potential to reduce the recurrence of leg ulceration and improve quality of life. The findings suggest that such a strategy needs to rationalize delivery of leg ulcer aftercare to provide seamless care. It needs to improve carers' and patients' understanding of factors influencing leg ulcer recurrence and facilitate development of a more balanced professional--patient relationship.

Preventing unnecessary suffering: an audit of a leg ulcer clinic

Unnecessary patient suffering and increased costs in leg ulcer care were reported in an Effective Health Care bulletin (NHS Centre for Reviews and Dissemination (NHSCRD), 1997). Follow-up assessment of patients with a history of venous ulceration has beneficial effects for patients' quality of life, and for effective and efficient management of resources for community nurses. This article describes the process of implementing evidence-based practice in a leg ulcer clinic in South London within existing resources, which resulted in the successful prevention of leg ulcer recurrence.

Standards of care for venous leg ulcers: compression therapy and moist wound healing

Venous ulcers are the most common type of cutaneous ulceration of the lower extremity, accounting for 70% to 90% of all cases. Despite recent advances in treatment and the development of new modalities, the current standard of care remains compression therapy in combination with appropriate moist wound care principles. The physiology of the venous system and the pathophysiology of venous disease leading to ulceration are described. A review of the use of gradient compression therapy is provided, including a discussion of several types. The history of moist wound healing and the use of hydrocolloids also are included. It is essential for the vascular nurse to be well versed in the areas of compression therapy and moist wound principles as the most effective treatment for venous ulcers at this time.

Wound care in the community setting: clinical decision making in context

Sixty-two community nurses in northern England of grades B and D to H were interviewed by a team of four researchers. The interviews were semi-structured, and were tape-recorded, fully transcribed and content analysed. They were conducted as part of a larger study, the aim of which was to examine community nurses' perceptions of quality in nursing care. One of the main themes the work focused on was decision-making as an element of quality. Data relating to wound care were considered from the perspective of the insights they offered into clinical decision-making. Data were interpreted in the light of a literature review in which a distinction had been made between theories which represented clinical decision-making as a linear or staged process and those which represented it as intuitive. Within the former category, three sub-categories were suggested: theorists could be divided into 'pragmatists', 'systematisers' and those who advocated 'diagnostic reasoning'. The interpretation of the data suggested that the clinical decisions made by community nurses in the area of wound care appeared largely intuitive, yet were also closely related to 'diagnostic reasoning'. They were furthermore based on a range of sources of information and justified by a number of different types of rationale.
