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

OBJECTIVE

In previous studies, venous ulcers (VUs) have been found to occur more often in patients with lower socioeconomic status. The aim of this study was to explore if socioeconomic factors influence the delay of referral to a vascular service or the time to healing after superficial venous intervention.

METHOD

In this prospective study, patients answered a questionnaire about the duration and recurrence of their VU, comorbidities, body mass index (BMI), smoking, alcohol, social and physical activities, ambulatory status, education, marital status, housing, perceived economic status and dependence on home care. Postoperative complications, VU healing and recurrence were noted one year after superficial venous intervention.

RESULTS

A total of 63 patients were included in this study (30 females and 33 males), with a mean age of 71.2 years (range: 37-92 years). Duration of the present VU in patients was: <3 months in 48%; 3-6 months in 27%; 6-12 months in 11%; and >12 months in 14%. Risk factors for delayed referral were recurrent VU (odds ratio (OR): 4.92; p=0.021); walking impairment (OR: 5.43; p=0.009) and dependence on home care (OR: 4.89: p=0.039) in a univariable analysis. The latter was the only significant finding in a multivariable analysis with socioeconomic risk factor (OR: 4.89; p=0.035). In 85% of patients, their VU healed without recurrence during one year follow-up. Healing took longer if the patients: were of older age (p=0.033); had a normal BMI (independent samples t-test, p=0.028); had a recurrent VU (OR: 5.00; p=0.049); or walking impairment (Fishers exact test, OR: 9.14; p=0.008), but no significant socioeconomic risk factors were found.

CONCLUSION

In this study, socioeconomic factors were not important risk factors for delayed referral of VU patients to a vascular service or prolonged healing time after superficial venous intervention.

Managing venous leg ulceration: variance and variety

Frameworks of care have been developed to enhance and standardise care for those with venous leg ulcers. Community nurses are faced with an array of frameworks and guidance documents on which to base their care. This article outlines and discusses variations in the information provided within the body of evidence relating to the care of venous leg ulcers. It is based on the findings of ongoing study for a PhD thesis.

Implementation of a varicose vein module added to Swedvasc, the Swedish National Registry for vascular surgery

OBJECTIVES

The addition of a varicose veins (VV) module to the existing Swedish National Registry for Vascular Surgery (Swedvasc) and its impact on quality of care were evaluated.

METHODS

Vascular departments and private VV clinics were invited to enter data from 2016.

RESULTS

Registrations were approximately 10,000 yearly but dropped to 5390 in 2022 when a fee was introduced for private clinics due to reduced funding. 88% more interventions were reported to Swedvasc 2020 than to the National Board of Health and Welfare. Regions differed in interventions per 100,000 inhabitants/year from 21 to 233 and in preoperative CEAP C4-6 from 30.8%-90.4%. Follow-up was 9.4%. These data contributed to the decision to prioritize the patient group for national guidelines and pathways of care, which will be monitored by Swedvasc.

CONCLUSIONS

A national VV registry with high coverage is possible and can contribute to national quality of care. The main challenge is funding.

Delayed referral of venous ulcers increases resource usage

OBJECTIVE

Venous insufficiency is often not readily recognized as a contributing etiology to nonhealing wounds by nonvascular surgery specialists, potentially delaying appropriate treatment to achieve wound healing and increasing healthcare costs. The objective of the present study was to understand the time and resources used before the definitive treatment of venous ulcers.

METHODS

A single-institution retrospective medical record review of C6 patients undergoing radiofrequency saphenous and perforator vein ablation from May 2016 to January 2018 identified 56 patients with 67 diseased limbs. The numbers of inpatient, emergency department, and wound care visits and the intervals to vein ablation from the initial evaluation of the ulceration by a healthcare provider were collected. The demographics, comorbidities, previous venous interventions, wound characteristics, duplex ultrasound imaging, and available wound healing follow-up through July 2018 were assessed for all patients.

RESULTS

For the 67 limbs examined, 588 total healthcare visits were performed for wound assessment before a referral to a vascular surgeon, with 413 visits at a wound care center (70% of all visits). Other specialty visits included emergency medicine (17.9% of limbs) and rheumatology (22.4% of limbs). Six patients (nine limbs) were admitted to inpatient services for treatment of their ulceration. Overall, the patients were seen an average of 8.6 ± 9.7 times for their ulcer with the wound center before determination of a contributing venous etiology and subsequent treatment. These visits translated to a median of 230 days (interquartile range, 86.5-1088 days) between the first identification of the ulcer by healthcare providers and subsequent accurate diagnosis and definitive treatment of their venous disease with radiofrequency saphenous and perforator vein ablation. After intervention, 18.64% of the limbs had healed at 1 month, 33.92% had healed at 3 months, 50% had healed at 6 months, and 82.92% had healed by 12 months.

CONCLUSIONS

An earlier and accurate diagnosis of the venous contribution to ulcers and subsequent appropriate treatment of venous etiologies in wound formation by a vascular venous specialist could significantly improve healing and minimize resource usage.

Primary care survey of venous leg ulceration management and referral pre-EVRA trial

Venous leg ulceration (VLU) is a public health concern that is largely managed in community settings. The present study aimed to survey current VLU management in the community. A 14-question survey was distributed to primary care professionals, and 90 responses were received. Some 54% of respondents stated that they would assess ankle brachial pressure indices (ABPI) for those with VLU, while 25% reported that they would not. Additionally, 62% reported not organising duplex ultrasound scanning. Compression therapy was offered by 82% of respondents. When asked whether VLU patients were referred to specialist services in secondary or tertiary care, some 32% reported that they would. However, 57% reported that, if a study suggested that referral to specialist services was beneficial, they would change their practice. On the basis of the findings, the authors concluded that there is diversity in VLU diagnostic and treatment pathways. New, high-quality evidence may improve practice, but care delivery is influenced by local factors including time and resource distribution.

Why nurses in primary care need to be research active: the case of venous leg ulceration

Venous leg ulceration (VLU) is predominantly managed in primary care by district nurses, however much of the research takes place in secondary care. This study aimed to identify to what extent nurses are involved in publishing VLU research and to ascertain how much VLU research is conducted in primary care. Three searches of literature published between 2015 and 2020 were undertaken, reviewing VLU publications on interventions, quality of life and qualitative research. Some 37% of intervention studies had one or more nurse authors, compared with 65% of quality of life studies and 86% of qualitative research publications. Of papers that providing details of recruitment, 39% of intervention and quality of life studies included primary care as a recruitment setting. Qualitative studies were more likely to recruit from primary as well as secondary care (50%). Nurses are involved in leading VLU research but are more likely to publish quality of life and qualitative research than intervention studies. The majority of nurse authors in this field are based in academic institutions. A minority of studies utilise primary care as a recruitment setting for VLU research. More must be done to enable VLU research in community settings and to promote the involvement of clinical nurses in research.

UK primary care survey of venous leg ulceration management and referral - Post-EVRA trial

Objective

Determine standards of referral and management of patients with venous leg ulceration in primary care after the release of the EVRA (A Randomized Trial of Early Endovenous Ablation in Venous Ulceration) study results.

Methods

An online questionnaire was disseminated over four months to professionals working within primary care.

Results

The survey received 643 responses. Of respondents, 90 (14%) had heard of the EVRA trial and 51 (8%) were familiar with the results. Of those who answered the following questions, 410 (69.1%) stated that referral to a vascular specialist must be made by the General Practitioner and 13 (2.2%) reported that they would always refer patients for secondary care assessment before the publication of EVRA. Considering the EVRA results, 128 (29%) reported that they would change practice regarding referral and would experience no barriers and 198 (45%) reported that they would like to refer earlier but is not their decision. Barriers to changing practice included local referral policies, training and time restrictions, 266 (59%) had heard of the NICE guideline (CG168) and 194 (43%) were aware of the recommendations for referral to a vascular service within two weeks for patients with an open or healed ulcer.

Conclusion

There is a considerable variation in local referral pathways for venous leg ulceration, and despite clinicians wanting to refer promptly, many primary care professionals are unable to. Unfortunately, the EVRA study alone may not change the overall practice, and work is needed to overcome barriers faced by primary care professionals.

The recommended goal in the United Kingdom's National Institute for Health and Care Excellence Clinical Guideline 168 for immediate referral of patients with bleeding varicose veins is not being achieved

OBJECTIVE

Published in July 2013, National Institute for Health and Care Excellence Clinical Guideline 168 (CG168) recommended that people with bleeding varicose veins be referred immediately to a vascular service. We have examined the impact of CG168 on referral practice for patients with bleeding varicose veins from primary to secondary care in a local National Health Service setting.

METHODS

Referrals to a local vascular service in the 6 years before (group 1) and 6 years after (group 2) publication of CG168 were analyzed to assess patients' management after a bleed, with particular reference to a patient's initial presentation and delays in referral to the vascular service. This was done by retrospective electronic database and case note interrogation of patients presenting with bleeding varicose veins. Relevant data were collected onto an Excel spread sheet (Microsoft, Redmond, Wash) in relation to demographic information, comorbidities, clinical presentation, and treatment pathway.

RESULTS

During the period studied, 73 patients presented with bleeding varicose veins. Their mean age was 66 years, and 56% were men. Their mean body mass index was 28 kg/m². Of note, 33 patients (45%) initially self-treated before going to see their general practitioner; another 18 (25%) went to the emergency department. In 51 patients (70%), the underlying superficial disease involved the great saphenous vein, and most patients (73%) were treated with foam sclerotherapy with or without truncal thermal ablation; 45 patients (group 1) were treated in the 6 years before publication of CG168, and 28 patients, allowing 6 months for dissemination, were treated in the 6 years after CG168 publication (group 2). Mean time from index bleed to referral to the vascular service was faster after publication of CG168 (84 days before and 20 days after publication of CG168; P = .00842). Publication of CG168 was also associated with reduced mean bleed to intervention times (194 vs 60 days; P = .00097).

CONCLUSIONS

Publication of UK National Institute for Health and Care Excellence guideline CG168 has been associated with a significant reduction in the delay to referral of patients presenting with bleeding varicose veins; however, the goal of immediate referral to a vascular service is not being met. CG168 is likely to have been a significant component of the factors that have led to the improvements seen thus far.

Correlation of disease comorbidity with prescribed treatment among insured U.S. lymphedema patients

OBJECTIVE

The objective of this study was to define the current forms of treatment in a contemporary population of lymphedema (LED) patients for LED related to breast cancer, the most prevalently diagnosed LED comorbidity in Western countries, and phlebolymphedema with venous leg ulcer (PLEDU), a sequela of chronic venous disease. The goals of LED therapy are to reduce edema, thereby improving function and related symptoms, and to improve skin integrity to prevent development of infection. Treatment is generally nonsurgical: conservative care, including complex physical therapy, manual lymphatic drainage, and compression bandaging; or pneumatic compression device (PCD) therapy by a simple nonprogrammable device or an advanced programmable device.

METHODS

To determine the frequency of individual types of treatment for LED and their relationship to breast cancer-related lymphedema (BCRL) and PLEDU, we queried claims from a deidentified Health Insurance Portability and Accountability Act-compliant commercial administrative insurance database with >165 million members. A total of 26,902 patients identified with LED who had been enrolled with continuous medical benefits for 12 months before and after the index date for the complete years 2012 through 2016 were separated into four treatment categories: no treatment, conservative care, simple PCD (SPCD), and advanced PCD. LED treatment was related to the BCRL and PLEDU comorbidities.

RESULTS

BCRL patients, who represented 32.1% of all study patients, made up 41% of all patients receiving conservative care and 24% of patients receiving PCD therapy. By contrast, PLEDU patients (9.6% of study patients) were proportionally under-represented in the conservative care group (7.8%) but composed a disproportionately high share of the PCD therapy group (17.7%). PLEDU patients represented 23.5% of all LED patients prescribed SPCD therapy, whereas BCRL patients composed 10.3% of total LED patient SPCD prescriptions (P < .001).

CONCLUSIONS

Our analysis of a large health care administrative database showed clear differences between the way BCRL and PLEDU patients are treated. Compared with BCRL patients, PLEDU patients were less likely to receive conservative care and more likely to be prescribed SPCDs for pneumatic compression therapy. These differences suggest that lymphatic therapy may be undervalued for treatment of chronic venous swelling and prevention and treatment of PLEDU.

The global management of leg ulceration: Pre early venous reflux ablation trial

BACKGROUND

Various guidelines exist worldwide for the diagnosis and management of venous leg ulcers; however, these are difficult to implement resulting in disparate treatment of patients globally.

METHOD

An online, 26-question survey was designed to evaluate the current global management of venous leg ulceration and was emailed globally to approximately 15,000 participants (November 2017-February 2018).

RESULTS

Overall, 799 responses were received from 86 countries, with a 5% response rate. The respondent physicians saw a median of 10 (interquartile range 5-20) patients per month, with a median time to referral from primary to secondary care of six weeks. Of the respondents, 61% arranged an ankle brachial pressure index on first visit and 84% performed a venous duplex, with 95% prescribing compression for those in whom it was not contraindicated. Fifty-nine percent performed endovenous intervention or surgery prior to ulcer healing.

CONCLUSIONS

The survey showed a diversity of treatment pathways. The need to develop a robust, clear pathway for patients with leg ulceration is clearly required.

A qualitative study on the patient's narrative in the progression of chronic venous disease into a first venous leg ulcer: a series of events

BACKGROUND

A venous leg ulcer (VLU) has a significant negative impact on quality of life. Prevention of a VLU is not yet imbedded in clinical practice because risk factors for developing a first VLU are not well known.

OBJECTIVES

To explore further the progression of chronic venous disease (CVD) into a first VLU from the patient's perspective.

METHODS

A qualitative study using semistructured interviews was conducted among male and female patients with a VLU. Patients from primary and secondary care, under and over 50 years of age, and with first and recurrent VLUs were included. The interviews were transcribed and analysed using a narrative approach to a thematic analysis. Transcripts were organized in chronological order and an iterative process was used to code the transcripts.

RESULTS

Four key themes and the connections made between them emerged from the 11 narratives on the progression of CVD towards a first VLU: 'comorbidity', 'mobility', 'work and lifestyle' and 'acknowledgment of CVD'. Comorbidity was linked to reduced mobility and late acknowledgment of CVD. Comorbidity also affected work and lifestyle and vice versa. Work and lifestyle affected mobility and was linked to the acknowledgment of CVD.

CONCLUSIONS

A reduction in mobility as a result of comorbidity and work and lifestyle occurred before the VLU developed. Patients did not recognize symptoms of CVD and did not acknowledge the chronicity of CVD. Healthcare professionals should be aware of reductions in mobility and the knowledge deficit in patients with CVD. What's already known about this topic? Not all patients with chronic venous disease (CVD) develop a venous leg ulcer (VLU). A patient's quality of life decreases significantly when a VLU develops. Risk factors for the development of a first VLU in patients with CVD are not well known, unlike risk factors for other chronic wounds like diabetic foot ulcer and pressure ulcers. What does this study add? The patient's narrative towards the development of a first VLU, a series of events. Insight into the events (comorbidity, mobility, work and lifestyle) that patients themselves link to the development of a VLU. Insight into the patients' acknowledgment of CVD in the progression of CVD towards a first VLU. What are the clinical implications of this work? More awareness is needed of CVD symptoms among patients and healthcare providers, as well as more awareness for prevention of a VLU in clinical practice. New insights (for further studies) are needed into the concept of mobility and the development of a VLU. Improved patient education and follow-up are needed for patients with CVD.
