Pressure-Measuring Devices for Compression Therapy in Venous Leg Ulcers: A Comprehensive Review

OBJECTIVE

To investigate the evolution of pressure-measuring devices used in compression treatment for venous leg ulcers and assess the most practical and effective devices to determine optimal pressure in compression therapy.

DATA SOURCES

Relevant information was retrieved from databases including Google Scholar, PubMed, Wiley Online, and ScienceDirect without publication date restrictions. The keywords included venous leg ulcer, compression therapy, pressure measuring device, pressure sensor, and wireless system.

STUDY SELECTION

Studies included in the review had to be published in English and discuss or compare pressure-measuring devices/sensors for compression therapy, the development of alternative sensors, and the applications of wireless technologies. Veterinary studies, conference proceedings, and unpublished articles were excluded. Applicable studies and articles were critically evaluated and synthesized.

DATA EXTRACTION

After abstract review, 39 studies were identified. During full-text review, study details were collected using a data extraction form and organized into tables. Device attributes, accuracy, price, and limitations were categorized and analyzed.

DATA SYNTHESIS

Studies disagree on the effectiveness and user-friendliness of existing pressure-measuring devices. These devices often impact user comfort and convenience, which are crucial factors in the adoption and use of wearable devices. Potential solutions for pressure-measuring devices with promising technologies were proposed: four feasible alternative sensors are described that could improve comfort and facilitate prolonged use under bandages. Advanced communication technologies may provide more convenience for users and practitioners.

CONCLUSIONS

Conventional pressure-measuring devices used in compression therapy are not designed for the user's comfort and convenience. The use of flexible and stretchy pressure sensors (e-skin) provides good biocompatibility, conformability, and comfort and when integrated with near-field communication technology could address the drawbacks of current pressure-measuring devices.

Common, But Neglected: A Comprehensive Review of Leg Ulcers in Sickle Cell Disease

OBJECTIVE

To compile available evidence to better understand the management of leg ulcers in sickle cell disease (SCD), as well as describe potential therapeutic steps that may be required to improve the quality of life of patients with SCD leg ulcers.

DATA SOURCES

MEDLINE, PubMed, EMBASE, and Web of Science databases.

STUDY SELECTION

A comprehensive search was conducted to retrieve relevant studies using the keywords "sickle cell disease and leg ulcer," "ulcer treatments, diagnosis and sickle cell," and "wound sickle cell." Studies published through July 2020 were included.

DATA EXTRACTION

Two independent authors selected all studies that assessed the relationship between leg ulcer and SCD identified from online databases.

DATA SYNTHESIS

The authors have summarized updated information on pathophysiology (vasculopathy linked to chronic hemolysis and endothelial dysfunction), diagnosis, and available treatment options to unravel the dermohematologic connection between leg ulcers and SCD.

CONCLUSIONS

It is the authors' hope that this detailed discussion of the information available on leg ulcers and SCD will lead to a better appreciation of this clinical problem by the clinicians and researchers and in turn have a long-term positive effect on the quality of life of patients with SCD. Researchers should design new trials considering these insights and potential therapeutic approaches based on current knowledge.

Lower Extremity Ulcers

Lower extremity ulcerations contribute to significant morbidity and economic burden globally. Chronic wounds, or those that do not progress through healing in a timely manner, are estimated to affect 6.5 million people in the United States alone causing, significant morbidity and economic burden of at least an estimated $25 billion annually. Owing to the aging population and increasing rates of obesity and diabetes mellitus globally, chronic lower extremity ulcers are predicted to increase. Here, we explore the pathophysiology, diagnosis, and management of the most (and least) commonly seen lower extremity ulcers.

The Effect of Bacterial Colonization and Maggot Debridement Treatment on Wound Healing in Chronic Venous Leg Ulcers

BACKGROUND

The debridement of necrotic and infected tissues, which prolong the wound healing process, is important for the preparation of the wound bed. Therefore, wound-bed preparation and debridement are vital components of venous leg ulcer management. We aimed to present a perspective to evaluate the clinical and microbiological efficacy of Maggot Debridement Therapy (MDT) in the treatment of chronic leg ulcers caused by venous insufficiency.

METHODS

Thirty-eight patients with chronic venous leg ulcers who were referred to our unit with an MDT request were included in the study. Lucilia sericata larvae were applied to the wounds two days a week until the necrotic tissue was cleared. Swab samples were regularly taken before and immediately after each larval application for wound culture. Changes in the percentage of wound surface area and growing pathogenic microorganisms were recorded during the follow-up period.

RESULTS

The sample consisted of 38 patients with 55 venous leg ulcers. The mean initial ulcer surface area was 99.1 cm2 (range 3 - 500). Complete debridement was achieved in all ulcers in the 2nd week, on average. Twenty-five ulcers (45.5%) were completely debrided with two one-week MDT sessions. Complete wound healing occurred in 42 ulcers (76.4%) after an average of seven MDT sessions. Microorganisms isolated from the wounds significantly decreased immediately after the first MDT session.

CONCLUSIONS

Although many methods are used in the treatment of venous leg ulcers, they are often not effective. MDT, which is coming into widespread use today, is a simple and effective method in the treatment of these ulcers. Its effects such as biodebridement, disinfection, and growth stimulation can encourage the rapid healing of chronic venous leg ulcers.

Bench-to-Bedside in Vascular Medicine: Optimizing the Translational Pipeline for Patients With Peripheral Artery Disease

Peripheral arterial disease is a growing worldwide problem with a wide spectrum of clinical severity and is projected to consume >$21 billion per year in the United States alone. While vascular researchers have brought several therapies to the clinic in recent years, few of these approaches have leveraged advances in high-throughput discovery screens, novel translational models, or innovative trial designs. In the following review, we discuss recent advances in unbiased genomics and broader omics technology platforms, along with preclinical vascular models designed to enhance our understanding of disease pathobiology and prioritize targets for additional investigation. Furthermore, we summarize novel approaches to clinical studies in subjects with claudication and ischemic ulceration, with an emphasis on streamlining and accelerating bench-to-bedside translation. By providing a framework designed to enhance each aspect of future clinical development programs, we hope to enrich the pipeline of therapies that may prevent loss of life and limb for those with peripheral arterial disease.

Human Wound and Its Burden: Updated 2020 Compendium of Estimates

Significance: Chronic wounds impact the quality of life (QoL) of nearly 2.5% of the total population in the United States and the management of wounds has a significant economic impact on health care. Given the aging population, the continued threat of diabetes and obesity worldwide, and the persistent problem of infection, it is expected that chronic wounds will continue to be a substantial clinical, social, and economic challenge. In 2020, the coronavirus disease (COVID) pandemic dramatically disrupted health care worldwide, including wound care. A chronic nonhealing wound (CNHW) is typically correlated with comorbidities such as diabetes, vascular deficits, hypertension, and chronic kidney disease. These risk factors make persons with CNHW at high risk for severe, sometimes lethal outcomes if infected with severe acute respiratory syndrome coronavirus 2 (pathogen causing COVID-19). The COVID-19 pandemic has impacted several aspects of the wound care continuum, including compliance with wound care visits, prompting alternative approaches (use of telemedicine and creation of videos to help with wound dressing changes among others), and encouraging a do-it-yourself wound dressing protocol and use of homemade remedies/substitutions. Recent Advances: There is a developing interest in understanding how the social determinants of health impact the QoL and outcomes of wound care patients. Furthermore, addressing wound care in the light of the COVID-19 pandemic has highlighted the importance of telemedicine options in the continuum of care. Future Directions: The economic, clinical, and social impact of wounds continues to rise and requires appropriate investment and a structured approach to wound care, education, and related research.

A relational database within the Leg Club Network: an audit

The growing prevalence of venous leg ulcers in an ageing population presents challenges for wound care and management. The Lindsay Leg Club model is an alternative approach to the management of leg health that can improve patient outcomes. This article reports on an audit of a relational database located within the Leg Club Network, containing records of more than 17 000 patients (known as members) who attended a Leg Club in a 5-year period (2014-2019). Overall, over 266 000 member leg assessments and treatments were entered into the database. The average nurse-member attendance time was 28 min, with a skill mix of 23% senior nurses, 70% qualified and associate nurses, and 7% nurses in supervisory roles. Healing rates averaged 62% after 12 weeks. Recurrence rates were 20% after 12 weeks. Annual clinical and volunteer hours averaged 821 and 800 h, respectively. Staffing costs were £28 per wound treatment or leg assessment with a typical duration of 27 min; 71% of members were aged 70 to 94 years old, which indicates the need for a service that caters to the specific requirements of this age group. However, no data on psychosocial and well-being outcomes were recorded. Their inclusion in further developments of this database is recommended.

Interventions for treating leg ulcers in people with sickle cell disease

BACKGROUND

The frequency of skin ulceration makes an important contributor to the morbidity burden in people with sickle cell disease. Many treatment options are available to the healthcare professional, although it is uncertain which treatments have been assessed for effectiveness in people with sickle cell disease. This is an update of a previously published Cochrane Review.

OBJECTIVES

To assess the clinical effectiveness and harms of interventions for treating leg ulcers in people with sickle cell disease.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register. We searched LILACS (1982 to January 2020), ISI Web of Knowledge (1985 to January 2020), and the Clinical Trials Search Portal of the World Health Organization (January 2020). We checked the reference lists of all the trials identified. We also contacted those groups or individuals who may have completed relevant randomised trials in this area. Date of the last search of the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register: 13 January 2020; date of the last search of the Cochrane Wounds Group Trials Register: 17 February 2017.

SELECTION CRITERIA

Randomised controlled trials of interventions for treating leg ulcers in people with sickle cell disease compared to placebo or an alternative treatment.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies for inclusion. All three authors independently assessed the risk of bias of the included studies and extracted data. We used GRADE to assess the quality of the evidence.

MAIN RESULTS

Six studies met the inclusion criteria (198 participants with 250 ulcers). Each trial investigated a different intervention and within this review we have grouped these as systemic pharmaceutical interventions (L-cartinine, arginine butyrate, isoxsuprine) and topical pharmaceutical interventions (Solcoseryl® cream, arginine-glycine-aspartic acid (RGD) peptide dressing and topical antibiotics). No trials on non-pharmaceutical interventions were included in the review. All trials had an overall unclear or high risk of bias, and drug companies sponsored four of them. We were unable to pool findings due to the heterogeneity in outcome definitions, and inconsistency between the units of randomisation and analysis. Three interventions reported on the change in ulcer size (arginine butyrate, RGD peptide, L-cartinine). Of these, only arginine butyrate showed a reduction of ulcer size compared with a control group, mean reduction -5.10 cm² (95% CI -9.65 to -0.55), but we are uncertain whether this reduces ulcer size compared to standard care alone as the certainty of the evidence has been assessed as very low. Three trials reported on complete leg ulcer closure (isoxsuprine, arginine butyrate, RGD peptide matrix; very low quality of evidence). None reported a clinical benefit. No trial reported on: the time to complete ulcer healing; ulcer-free survival following treatment for sickle cell leg ulcers; quality of life measures; incidence of amputation or harms.

AUTHORS' CONCLUSIONS

Given the very low quality of the evidence identified in this updated Cochrane Review we are uncertain whether any of the assessed pharmaceutical interventions reduce ulcer size or result in leg ulcer closure in treated participants compared to controls. However, this intervention was assessed as having a high risk of bias due to inadequacies in the single trial report. Other included studies were also assessed as having an unclear or high risk of bias. The harm profile of the all interventions remains inconclusive.

Successful Treatment of a Venous Leg Ulcer With Manuka Honey: A Case Study

BACKGROUND

Refractory venous leg ulcers (VLUs) often require extended time to heal, and they carry a high risk of recurrence. This case study describes our experiences with a patient with a VLU refractory to multiple treatment strategies who was successfully treated with Manuka honey.

CASE

Mr S. was a 76-year-old man with multiple comorbid conditions and hypersensitivity to silver-based compounds, who developed 3 VLUs of his right lower extremity. He experienced 90 days of unsuccessful treatments using an iodized cadexomer ointment, hydrodetersive fiber dressings, hydrocolloid meshes, compression therapy, and antibiotic treatment without progression toward wound healing. We then initiated treatment with Manuka honey and continued compression therapy. His primary VLU was completely epithelialized within 38 days, and an adjacent VLU also showed progression toward healing. Mr S. reported clinically relevant improvement in wound-related pain at 17 days.

CONCLUSION

The use of Manuka honey proved effective in this patient with a VLU refractory to other treatment strategies.

Implementing a Locally Made Low-Cost Intervention for Wound and Lymphedema Care in Western Kenya

In Western Kenya, the burden of chronic wounds and lymphedema has a significant impact on functionality and quality of life. Major barriers to provision of care include availability, affordability, and accessibility of bandages. At the Academic Model Providing Access to Healthcare, dermatologists and pharmacists collaborated to develop a 2-component compression bandage modeled after the Unna boot, using locally available materials, that is distributed through a revolving fund pharmacy network. In partnership with nursing, use of these bandages at a national referral hospital and a few county facilities has increased, but increasing utilization to an expanded catchment area is needed.

An audience survey of practice relating to pain in the management of chronic venous leg ulcers

Venous leg ulcers (VLU) respond well to compression, yet many ulcers remain unhealed after 1 year. Practitioners could be reluctant to apply compression to patients with significant ulcer pain. This study aimed to capture the views of practitioners on compression therapy for patients with painful VLU. A survey was conducted at a UK meeting in 2019 using handheld voting pads to capture the anonymous responses to four questions to which a mean of 90 practitioners responded. Nearly 40% of practitioners treat six or more patients a day with painful lower-limb ulcers. Some 80% felt confident in managing patients with painful ulcers; yet, most practitioners suggested they would refer onward for pain management. Some 40% would omit or reduce compression therapy as a pain management strategy. This survey supports the need for technological solutions that reduce VLU pain so that patients receive effective compression therapy.

Rationale for participation in venous leg ulcer clinical research: Patient interview study

Recruitment to wound care clinical trials is challenging and a better understanding of patient decisions to participate has the potential to influence recruitment success. We conducted 31 semi-structured telephone interviews of patients who participated in the Aspirin in Venous Leg Ulcer (ASPiVLU) randomised controlled trail (RCT) or ASPiVLU cohort study. Data were coded and analysed using thematic analysis. We identified four key themes: (a) "I participated to help others"; (b) "I participated in research to thank those who cared for me"; (c) "I participated to receive better care"; and (d) "I participated to have a say on what works." These themes became basic elements for the Rationale for Research Participation Framework that we have developed to improve the participant recruitment process for clinical trials in wound care.

[Non-healing wounds]

The incidence of non-healing wounds is increasing. Identification of the underlying cause of a wound is of essential importance for adequate treatment. In this article, we present three female patients aged 50, 65 and 85 years with respectively pyoderma gangraenosum, livedoid vasculopathy and Martorell hypertensive ischaemic leg ulcer. All patients were treated with local wound care for weeks without a valid diagnosis. In retrospect it can be concluded that several warning signals had not been recognised. Severe pain, atypical location or appearance, insufficient healing and progression of the wound despite adequate wound care should all be considered red flags. Patients with non-healing wounds require prompt referral and more extensive diagnostic investigation. Our cases also show that a multidisciplinary wound care team ensures and accelerates consensus on diagnosis and treatment plan. Such a team can ensure and coordinate follow-up in the home environment.

The TLC-NOSF (Technology Lipido-Colloid Plus Nano-Oligo Saccharide Factor) protease inhibitor for the treatment of ulceration in rheumatic disease A case report

Cutaneous Lupus Erithematosus is one of the most common manifestation of Systemic Lupus Erithematosus and can be featured by the onset of cutaneous vasculitis which can bring to skin ulcers, expecially on the extremities. The "common" aetiopathogenesis can be summarized as following: 1) an antiself response to the endothelial cells which brings to frequent ischemic or thrombotic episodes, 2) the drugs therapy; recently authors have been demostrated a correlation between Metalloproteinase Matrix (MMP) and Cutaneous LES. Here we present the case of a 33 y.o. woman affected by a rheumatic disorder, which has developed a chronic ulcer on her left leg. After several and different unsuccessful approaches, as homologous and autologous skin graft, and considering both the refusal of other surgery even if enhanced by Negative Pressure Therapy and the compromised vascularization which contraindicated the use of flaps, we decided to use a dressing based on the TLC-NOSF (Technology Lipido-Colloid plus Nano-Oligo Saccharide Factor) protease inhibitor, a metalloproteinase regulator. The dressing was changed 2 times/week for the first 2 months and 1 time/week for other 2 months. The ulcer became smaller at every session and we obtained a full coverage at 4th month. KEY WORDS: Nano-oligo saccharide factor, Wound.

Safety and efficacy of larval therapy on treating leg ulcers: a protocol for systematic review and meta-analysis

INTRODUCTION

Leg ulcers (LUs) not only seriously affect life and work of patients, but also bring huge economic burden to the society. As a potential underused biological debridement, larval therapy provides help for the treatment of LUs. The purpose of our research is to assess whether patients with LUs can benefit from larval therapy.

METHODS AND ANALYSIS

The following electronic databases will be searched: PubMed, EMBASE, Web of Science, the Cochrane Library, China National Knowledge Infrastructure Database, Wanfang Database and Chinese Biological Medicine. Randomised controlled trials are eligible for inclusion. There will be no restrictions with respect to language and search date is up to June 2020. Primary outcomes investigated are complete healing rate after treatment, time to ulcer healing, reduction of wound surface area and adverse events. Risk ratios will be used for categorical data; weighted mean difference will be used for measurement data. Subgroup analysis and sensitivity analysis will be considered if heterogeneity exists. The results of data synthesis will be performed by narrative summary and quantitative analysis.

ETHICS AND DISSEMINATION

This systematic review does not require the approval of the ethics committee because individual data on patients are not collected. The results of the study will be disseminated in peer-reviewed journals.

The use of intermittent pneumatic compression of the thigh to affect arterial and venous blood flow proximal to a chronic wound site

Intermittent pneumatic compression of the lower limbs has been shown to have beneficial effects in patients with chronic ulceration. However, the intermittent compression cuff will normally be applied over the wound, which may produce discomfort or interfere with other treatments. Thigh-only approaches to intermittent pneumatic compression could solve this problem. This study aimed to demonstrate if such a system would have positive effects on venous and arterial blood flow distal to the compression site, but proximal to wound sites. The distal venous and arterial effects of a prototype thigh-only 3-chamber sequential intermittent pneumatic compression system were tested in 20 healthy volunteers, and 13 patients with ulcers of various aetiologies using Doppler ultrasound. The system produced hyperaemic responses in the arterial flow of both test groups. The peak venous velocity on deflation of the first and second chambers of the cuff was also greater in the patients with ulceration than in the healthy volunteers (11.6 cm/s vs 8.3 cm/s, P = .1). This work demonstrates that compression of the thigh alone can produce positive haemodynamic effects in the calves of patients with chronic wounds, and that this approach should be investigated as a therapy to improve blood flow to wound sites.

The management of malignant lower limb ulcers: clinical considerations

Lower limb malignant ulcers are an uncommon finding, making diagnosis complex and their management costly. Yet, despite this, the increase in skin cancers over the past 30 years means that clinicians require an awareness and understanding of their existence, particularly in the primary care setting. Familiarity with common aetiologies and presentations is vital for prompt recognition, diagnosis and referral of wounds suspicious for malignancy. Lower limb malignant wounds often develop insidiously, with a wide variation in clinical presentation that overlaps between entities. Therefore, a fundamental algorithm for approaching lower limb ulcers that raise suspicion of malignancy should be possessed by all clinicians. This article reviews the clinical features of malignant wounds that should alert clinicians to the need for further evaluation, such as atypical location and appearance. The authors also highlight the various diagnostic and therapeutic modalities available and review current clinical guidelines for the referral and follow-up of suspicious lesions.

Microcirculatory Flux and Pulsatility in Arterial Leg Ulcers is Increased by Intermittent Neuromuscular Electrostimulation of the Common Peroneal Nerve

BACKGROUND

Neuromuscular electrical stimulator (NMES) devices increase blood flow to the lower limb by a process of intermittent muscular contraction initiated by a transdermal stimulus to the common peroneal nerve. However, its effects on localized microvascular blood supply to lower limb wounds are unknown. This study is a single-center open label study measuring the effect of neuromuscular stimulation of the common peroneal nerve on the microvascular blood flow within the wound bed of arterial leg ulcers.

METHODS

Eights patients with ischemic lower limb wounds had an NMES (geko™) applied to the common peroneal nerve. Baseline and intervention analysis of blood flow to the wound bed and edge was performed using Laser Speckle Contrast Imaging. Mean flow (flux) and pulse amplitude (pulsatility) were measured.

RESULTS

Stimulation of the common peroneal nerve with the NMES resulted in a significantly increased flux and pulsatility in both the wound bed and the wound edge in all 8 patients.

CONCLUSIONS

Neuromuscular electrical stimulation immediately increases microcirculatory blood flow to the wound bed and edge in patients with ischemic lower limb wounds. These data may provide mechanistic insight into the clinical efficacy of NMES in healing wounds. www.clinicaltrials.gov NCT03186560.

Outcomes and Characteristics of Wound Healing in an Outpatient Physical Therapy Clinic

INTRODUCTION

Detailed understandings regarding the outcomes and characteristics of healing in wounds of different etiologies are lacking.

OBJECTIVE

In the present study, data on 265 patients treated at an outpatient physical therapy wound care clinic were extracted.

METHODS

Using Kaplan-Meier analyses, wound healing outcomes for different wound etiologies were evaluated and compared.

RESULTS

The results revealed venous leg ulcers (VLUs) healed faster than non-VLUs, pressure ulcers (PUs), diabetic foot ulcers (DFUs), and arterial wounds but not faster than surgical and traumatic wounds (STWs). The estimated medians (mean for arterial wounds) of total treatment durations for complete wound closure were 87, 152, 100, 170, 525.44, 773 days in VLUs, non-VLUs, STWs, DFUs, arterial wounds, and PUs, respectively. Compared with patients with VLUs, patients with non-VLUs were younger (69.72 vs. 61.35, respectively), had a higher proportion of men (odds ratio [OR] = 2.26), were less likely to have more than 1 wound (OR = 0.25), reached complete wound closure upon discharge (OR = 0.41), or had a body mass index value greater than or equal to 25 (OR = 0.39).

CONCLUSIONS

Venous leg ulcers and other wound etiologies (ie, STWs, PUs, DFUs, and arterial wounds) appear to differ in wound healing outcomes and certain characteristics. These results may be of interest to clinicians, patients, health care policy makers, and insurers. Future research is warranted to compare wound healing outcomes and patient characteristics among different settings.

Primary care networks: an opportunity to improve community wound care

Primary care networks (PCNs) were introduced in England in 2019 to bring about closer collaboration between general practice and community health services. The ambition is that greater collaboration between services will achieve better patient outcomes and reduce costs through more effective sharing of staff and resources. Wound care might be considered an ideal focus for PCNs, since general practice and community health services not only have a predominant role in the management of wounds, but variable and suboptimal practice continues and poor outcomes persist. This article investigates some ways in which PCNs might enable health-system changes that could improve the provision of wound care.

The Ears of a Hippopotamus: Quality of Venous Leg Ulcer Care in Gauteng, South Africa

OBJECTIVE

To describe venous ulcer care and wound care practices in Gauteng, a province of South Africa, according to the Donabedian structure-process-outcome quality improvement model.

METHODS

Forty-eight facilities were selected randomly from public and private wound care practices in Gauteng. Structured interviews were conducted with care providers via questionnaire to assess the structural aspects of the Donabedian model. Within these facilities, investigators randomly selected 160 patient files and extracted data using a checklist to assess processes implemented and outcomes reached for patients who had previously presented with lower-leg venous ulcers.

RESULTS

Facilities lack the necessary equipment to perform vital assessments. Handheld Dopplers were available in 66% (n = 48) of the facilities. Sixty-one percent (n = 48) of the personnel at the facilities indicated that they had no formal wound care training. Although the majority of files (92%, n = 147) indicated that an assessment tool was used, many elements were not evaluated comprehensively according to the best available evidence. Aspects such as smoking, body mass index, and anemia were assessed in fewer than 30% of the patients. Distinguishing between superficial and deep infection and the accompanying overuse of antimicrobials and antibiotics were among the challenges identified. Further, 71% of patients received compression therapy, although the ankle-brachial pressure index of only 30% of patients was known. In 27 cases (17%), the outcome was amputation.

CONCLUSIONS

From this survey, it is evident that not all clinicians providing wound care in Gauteng are adequately trained or fully implementing best practice guidelines, and the consequences are detrimental to patients, particularly in terms of amputation. This article highlights the need for improved legislation and regulation for practitioners who deliver wound care services.
