Improved wound management at lower cost: a sensible goal for Australia

Burden of Chronic Nonhealing Wounds: An Overview of the Worldwide Humanistic and Economic Burden to the Healthcare System

Chronic wounds have long been a significant public health concern, but the true impact of these wounds is unknown since research designs and measuring techniques vary, leading to inconsistent estimates. The definition of a wound is a loss of epithelial continuity caused by damage to the tissue. The following conditions can cause chronic wounds: panniculitis, pyoderma gangrenosum, traumatic, neurological, metabolic, hematologic, neoplastic, or infection-related. The growing global incidence of diabetes and the aging population necessitate greater attention to chronic wounds. Regrettably, it is sad that significant healthcare institutions have overlooked wound research. The study of health-related illnesses and occurrences in particular populations, including their distribution, frequency, and determinants, and the application of this research to control health problems.

The client and family experience of attending a nurse-led clinic for chronic wounds

BACKGROUND

The quality of life for individuals with chronic wounds is diminished due to poor health-related outcomes and the financial burden of wound care. The literature has shown nurse-led wound care to have a positive impact on wound healing and psychosocial wellbeing. However, there is minimal research investigating the lived experience of attending a nurse-led clinic for chronic wounds. The purpose of this study was to explore the client and family experience of attending a nurse-led clinic for chronic wounds.

METHODS

Qualitative descriptive study. Semi-structured telephone interviews were transcribed verbatim and thematic analysis was undertaken.

RESULTS

Twelve clients and two family members participated, and the average length of interviews was 20min. Three main themes emerged: (1) expecting and managing pain; (2) receiving expert advice and reflecting on previous care; and (3) managing the cost of care. There was an emphasis on the impact of chronic wounds on pain and the ability to complete the activities of daily living. Expert advice, client satisfaction and physical accessibility were highlighted as benefits of the clinic. Cost and minimal client education were identified as challenges of the clinic.

CONCLUSIONS

The findings demonstrated that chronic wounds have a significant impact on the client and family attending the nurse-led clinic. Comprehensive pain assessment, improved social support, better client education and cost-effective care is required to optimise the experience for people attending the nurse-led clinic.

The financial burden of diabetes-related foot disease in Australia: a systematic review

BACKGROUND

Diabetes-related foot disease (DFD) is a common, costly, and severe complication of diabetes mellitus. DFD is associated with high rates of morbidity and mortality and poses a significant burden on patients, healthcare systems and society. While the detrimental impact of DFD is widely recognised, the precise financial implications of its management in Australia remain unclear due to inconsistent and inconclusive contemporary data. Therefore, the aim of this review was to identify, summarise and synthesise existing evidence to estimate the costs associated with DFD management in Australia.

METHODS

Searches were conducted in MEDLINE, Embase, AMED, CINAHL, Joanna Briggs Institute EBP, and the Cochrane Library from November 2011 to July 2023. Australian studies investigating costs associated with DFD management were eligible for inclusion. Two independent reviewers performed the study selection, data extraction and quality assessment steps. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS 2022) checklist was used to assess study quality. A descriptive analysis was performed due to limited existing evidence and large heterogeneity between study populations to conduct meta-analyses.

RESULTS

Three economic evaluations were included in the review. One study was rated as 'poor', one as 'very good' and one as 'excellent' when assessed against the CHEERS checklist. The estimated cost of DFD management varied between studies and comparisons were not possible due to the different methodological approaches and data sources. The studies were unable to provide an overall cost of DFD with respect to all aspects of care as they did not capture the multi-faceted level of care throughout the entire patient journey between sectors and over time.

CONCLUSION

There is limited contemporary evidence for the costs associated with DFD management within Australia, particularly related to direct costs and resource utilisation. Further research into the economic impact of DFD management is needed to inform optimisation of national service delivery and improve health outcomes for individuals with DFD in Australia. Integrating real-world data on impact of clinical interventions with parallel economic evaluation could be a valuable approach for future research, which would offer a more comprehensive understanding of the clinical and economic outcomes beyond solely model-based evaluations.

Assessing the healthcare costs associated with venous leg ulcer compression bandages - A scoping review

AIM

To determine the monetary costs identified in economic evaluations of treatment with compression bandages among adults with venous leg ulcers (VLU).

METHOD

A scoping review of existing publications was conducted in February 2023. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used.

RESULTS

Ten studies met the inclusion criteria. To place the costs of treatment into context, these are reported in conjunction with the healing rates. Three comparisons were made: 1.4 layer compression versus no compression (3 studies). One study reported that 4 layer compression was more expensive than usual care (£804.03 vs £681.04, respectively), while the 2 other studies reported the converse (£145 vs £162, respectively) and all costs (£116.87 vs £240.28 respectively). Within the three studies, the odds of healing were statistically significantly greater with 4 layer bandaging (OR: 2.20; 95% CI: 1.54-3.15; p = 0.001).; 2.4 layer compression versus other compression (6 studies). For the three studies reporting the mean costs per patient associated with treatment (bandages alone), over the treatment period, analysis identified a mean difference (MD) in costs for 4 layer vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) of -41.60 (95% CI: 91.40 to 8.20; p = 0.10). The OR of healing for 4 layer compression vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 0.70 (95% CI: 0.57-0.85; p = 0.004). For 4 layer vs comparator 2 (2 layer compression) the MD is: 14.00 (95% CI: 53.66 to -25.66; p < 0.49). The OR of healing for 4 layer compression vs comparator 2 (2 layer compression) is: 3.26 (95% CI: 2.54-4.18; p < 0.00001). For comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) vs comparator 2 (2 layer compression) the MD in costs is: 55.60 (95% CI: 95.26 to -15.94; p = 0.006). The OR of healing with Comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 5.03 (95% CI:4.10-6.17; p < 0.00001). Three studies presented the mean annual costs per patient associated with treatment (all costs). The MD is 172 (150-194; p = 0.401), indicating no statistically significant difference in costs between the groups. All studies showed faster healing rates in the 4 layer study groups. 3. Compression wrap versus inelastic bandage (one study). Compression wrap was less expensive than inelastic bandage (£201 vs £335, respectively) with more wounds healing in the compression wrap group (78.8%, n = 26/33; 69.7%, n = 23/33).

CONCLUSION

The results for the analysis of costs varied across the included studies. As with the primary outcome, the results indicated that the costs of compression therapy are inconsistent. Given the methodological heterogeneity among studies, future studies in this area are needed and these should use specific methodological guidelines to generate high-quality health economic studies.

Titanium Dioxide Nano-Formulation: Characterization, Antimicrobial Activity, and Wound Healing in Animals

The use of metal oxide nanoparticles as an alternative antimicrobial agent has gained attention due to the increasing problem of antimicrobial resistance. Understanding its properties and potential benefits can contribute to the development of more effective and sustainable treatments in veterinary medicine. The aim of this study was to characterize TiO2-NP formulations and evaluate their antibacterial and wound healing abilities. The diameters and zeta potentials were determined using the Zetasizer in conjunction with dynamic light scattering. The agar-well diffusion method, time-kill kinetic assay and crystal violet assay were used to evaluate their antimicrobial activities. Wound healing assays were conducted both in vitro and in vivo. The study demonstrated that TiO2-NP formulations exhibit significant antimicrobial properties against various bacterial strains such as S. aureus and E. coli. No measurable E. coli growth was observed within a 15-min period following exposure to TiO2-NP formulations. The TiO2-NP formation can improve wound healing by enhancing cell migration and collagen formation in both in vitro and in vivo conditions. In summary, our study suggests that TiO2-NP has the potential for use as an antimicrobial agent for animal wound treatment due to its ability to suppress bacterial growth and biofilm formation, as well as to enhance wound healing.

Comparison of the effectiveness of assisted turning mattresses and conventional air mattresses in relieving body pressure in different lying positions

Pressure ulcers are a common problem among individuals who, for medical reasons, must spend most of their day in bed. Manually turning a person's body is labor intensive and can easily cause occupational injuries. To compare the effectiveness of a new assisted turning mattress in pressure management with that of a conventional air mattress. This is a single-session crossover trial study. Twenty-four participants confined to bed were transferred onto the selected mattress (assisted turning or conventional air mattresses) in the selected position. Average interface pressures of bony prominences were measured after the participants laid on the mattress in different positions. After the data collection, they were transferred to the second mattress, and the process was repeated. Subjective feedback from participants and caregivers was also acquired immediately following a one-week trial period of assisted turning mattresses. The mean interface pressures were comparable for most body parts between two mattresses. Subjective feedback showed that assisted turning mattresses could relieve caregivers' workload but at the cost of patients' decreased feelings of safety. Assisted turning mattresses are equal to conventional air mattresses in pressure distribution. Proper pressure management through scheduled positional changes is required in assisted turning mattresses.

Effectiveness of Semi-Supervised Active Learning in Automated Wound Image Segmentation

Appropriate wound management shortens the healing times and reduces the management costs, benefiting the patient in physical terms and potentially reducing the healthcare system's economic burden. Among the instrumental measurement methods, the image analysis of a wound area is becoming one of the cornerstones of chronic ulcer management. Our study aim is to develop a solid AI method based on a convolutional neural network to segment the wounds efficiently to make the work of the physician more efficient, and subsequently, to lay the foundations for the further development of more in-depth analyses of ulcer characteristics. In this work, we introduce a fully automated model for identifying and segmenting wound areas which can completely automatize the clinical wound severity assessment starting from images acquired from smartphones. This method is based on an active semi-supervised learning training of a convolutional neural network model. In our work, we tested the robustness of our method against a wide range of natural images acquired in different light conditions and image expositions. We collected the images using an ad hoc developed app and saved them in a database which we then used for AI training. We then tested different CNN architectures to develop a balanced model, which we finally validated with a public dataset. We used a dataset of images acquired during clinical practice and built an annotated wound image dataset consisting of 1564 ulcer images from 474 patients. Only a small part of this large amount of data was manually annotated by experts (ground truth). A multi-step, active, semi-supervised training procedure was applied to improve the segmentation performances of the model. The developed training strategy mimics a continuous learning approach and provides a viable alternative for further medical applications. We tested the efficiency of our model against other public datasets, proving its robustness. The efficiency of the transfer learning showed that after less than 50 epochs, the model achieved a stable DSC that was greater than 0.95. The proposed active semi-supervised learning strategy could allow us to obtain an efficient segmentation method, thereby facilitating the work of the clinician by reducing their working times to achieve the measurements. Finally, the robustness of our pipeline confirms its possible usage in clinical practice as a reliable decision support system for clinicians.

Magnetite-Based Nanostructured Coatings Functionalized with Nigella sativa and Dicloxacillin for Improved Wound Dressings

In this study, we report the performance improvement of wound dressings by covering them with magnetite-based nanostructured coatings. The magnetite nanoparticles (Fe₃O₄ NPs) were functionalized with Nigella sativa (N. sativa) powder/essential oil and dicloxacillin and were synthesized as coatings by matrix assisted pulsed laser evaporation (MAPLE). The expected effects of this combination of materials are: (i) to reduce microbial contamination, and (ii) to promote rapid wound healing. The crystalline nature of core/shell Fe₃O₄ NPs and coatings was determined by X-ray diffraction (XRD). Differential Scanning Calorimetry (DSC) and Thermo Gravimetric Analysis (TGA) have been coupled to investigate the stability and thermal degradation of core/shell nanoparticle components. The coatings' morphology was examined by scanning electron microscopy (SEM). The distribution of chemical elements and functional groups in the resulting coatings was evidenced by Fourier transform infrared (FTIR) spectrometry. In order to simulate the interaction between wound dressings and epithelial tissues and to evaluate the drug release in time, the samples were immersed in simulated body fluid (SBF) and investigated after different durations of time. The antimicrobial effect was evaluated in planktonic (free-floating) and attached (biofilms) bacteria models. The biocompatibility and regenerative properties of the nanostructured coatings were evaluated in vitro, at cellular, biochemical, and the molecular level. The obtained results show that magnetite-based nanostructured coatings functionalized with N. sativa and dicloxacillin are biocompatible and show an enhanced antimicrobial effect against Gram positive and Gram negative opportunistic bacteria.

Frugal innovation in wound care: a critical discussion of what we can learn from low-resource settings

Frugal innovation is a common philosophy in low-income settings due to limited access to resources. However, with both the increasing prevalence and clinical acuity of patients with wounds in the UK, it is essential that alongside innovation such as harnessing cutting-edge new technologies, frugal innovation is also pursued. This may improve both economic efficiency and patient outcomes. Frugal innovations were adopted throughout the COVID-19 pandemic and included opportunistic solutions such as video-conferencing services to run clinics. However, there are many more opportunities for frugal innovation in wound care, including the use of smartphone technology, which is already accessible to 99.5% of UK clinicians caring for wounds, or the simplification of wound-assessment processes using pulse oximeters as an alternative to dopplers, as in the Lanarkshire Oximetry Index. This article explores what frugal innovation is and how it could improve UK wound services. The authors invite clinicians working in wound care to consider their access to existing resources that may not be considered useful for wound-care processes and explore how these could be used to improve clinical outcomes.

The viability and acceptability of a Virtual Wound Care Command Centre in Australia

The objective of this study was to assess the viability and acceptability of an innovative Virtual Wound Care Command Centre where patients in the community, and their treating clinicians, have access to an expert wound specialist service that comprises a digitally enabled application for wound analysis, decision-making, remote consultation, and monitoring. Fifty-one patients with chronic wounds from 9 centres, encompassing hospital services, outpatient clinics, and community nurses in one metropolitan and rural state in Australia, were enrolled and a total of 61 wounds were analysed over 7 months. Patients received, on average, an occasion of service every 4.4 days, with direct queries responded to in a median time of 1.5 hours. During the study period, 26 (42.6%) wounds were healed, with a median time to healing of 66 (95% CI: 56-88) days. All patients reported high satisfaction with their wound care, 86.4% of patients recommended the Virtual Wound Care Command Centre with 84.1% of patients reporting the digital wound application as easy to use. Potential mean travel savings of $99.65 for rural patients per visit were recognised. The data revealed that the Virtual Wound Care Command Centre was a viable and acceptable patient-centred expert wound consultation service for chronic wound patients in the community.

Primary Care Wound Clinics: A Qualitative Descriptive Study of Patient Experiences in Community Pharmacies

The expansion of primary care wound services serves to alleviate secondary and tertiary care utilization. However, patient satisfaction is required to ensure service uptake. In recent years, various community pharmacies in Australia have begun to offer dedicated wound clinics; however, evaluations of patient experiences have yet to be conducted. Thus, the present study seeks to explore: (1) the experiences and satisfaction of patients who have received wound care consultations for their acute wounds in a community pharmacy setting; and (2) how current pharmacy-based wound services can be improved. Semi-structured individual interviews were conducted with patients across five pharmacy-based wound care clinics in Western Australia. Interviews were audio-recorded, transcribed verbatim, and imported into QSR NVivo 12 Plus. Interview transcripts were coded and thematically analyzed using the framework method. Twelve interviews were required to reach data saturation. Five key themes emerged: the accessibility of wound services, the comprehensiveness of wound care services, confidence in wound care consultants, the awareness and promotion of wound services, and the expansion of wound care services. Overall, participants were satisfied with the accessibility and comprehensiveness of pharmacy-based wound service delivery, trusted the health care providers, and wanted the service to be expanded. The reported patient satisfaction, confidence in the health care provider, and desire to expand the service suggests there is potential for the service to grow in Australia. Due to the growing costs of wound care globally, there is scope to further evaluate and expand wound care services in the primary care setting on an international level.

A Comparative Study Between Vacuum Dressing and Normal Saline Dressing for Chronic Non-Healing Ulcers

Introduction

Isn’t it a boon that all living organisms possess the ability to heal their injuries? The wound healing is faster when the normal physiology of the wound healing is maintained. Our understanding of wound healing has undergone dramatic changes in the recent past. Almost all materials and methods available on earth have been used and tested to facilitate the process of wound healing. The mental agony and the disability suffered by patients with chronic ulcers have led to the reappraisal of the basic components of the wound healing process and how they are influenced by biological, mechanical, and physical forces.

The Department of General Surgery in our Government Chengalpattu Medical College and Hospital, Chengalpattu, Tamil Nadu, India, admits and treats a large volume of patients with wounds and ulcers. Here many materials are being used regularly for dressing to make wound healing faster. Vacuum dressings were also done on many patients, and promising results were observed. This kindled our interest in conducting this prospective study and comparing wound healing with vacuum dressing versus normal saline dressing.

Materials and methods

A total of 74 patients were included in the study, out of which 37 patients were randomly included in the experimental group and vacuum dressing was done, while the other 37 included in the control group were treated with dressing done with normal saline moistened gauze and bandage roll. Rates at which the wound healed were compared.

Results

We were able to observe a statistically significant difference in the rate of appearance of granulation tissue between the two and increased clearance of bacteria and toxins. The study group promised better progress as compared to the control group in various aspects.

Conclusion

Vacuum dressing brings an obvious improvement in the healing of non-healing ulcers and decreases the overall duration of stay in the hospital.

A narrative review of the epidemiology and economics of chronic wounds

Chronic wounds have a debilitating effect on the quality of life of many individuals, and the large economic impact on health system budgets warrants greater attention in policy making and condition management than is currently evident. The aim of this narrative review is to summarize the nature and extent of the chronic wound problem that confronts health systems across the world. The first section is used to highlight the underlying epidemiology relating to chronic wounds, while the second explores the economic costs associated with them and the relative efficiency of measures designed to manage them.

International study to develop the WOUND-Q patient-reported outcome measure for all types of chronic wounds

Patient‐reported outcome measures (PROMs) for chronic wounds mainly focus on specific types of wounds. Our team developed the WOUND‐Q for use with all types of wounds in any anatomic location. We conducted 60 concept elicitation interviews with patients in Canada, Denmark, the Netherlands, and the United States. Analysis identified concepts of interest to patients and scales were formed and refined through cognitive interviews with 20 patients and input from 26 wound care experts. Scales were translated into Danish and Dutch. An international field‐test study collected data from 881 patients (1020 assessments) with chronic wounds. Rasch measurement theory (RMT) analysis was used to refine the scales and examine psychometric properties. RMT analysis supported the reliability and validity of 13 WOUND‐Q scales that measure wound characteristics (assessment, discharge, and smell), health‐related quality of life (life impact, psychological, sleep impact, and social), experience of care (information, home care nurses, medical team, and office staff), and wound treatment (dressing and suction device). The WOUND‐Q can be used to measure outcomes in research and clinical practice from the perspective of patients with any type of wound.

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.

Venous leg ulcer management in Australian primary care: Patient and clinician perspectives

BACKGROUND

Venous leg ulcers are the most common chronic wound seen in Australian primary care. Healing outcomes are protracted due to suboptimal use of clinical practice guideline recommendations. A better understanding of the differences between patients and clinicians may optimise management in primary care and improve healing and health outcomes for patients and healthcare spend in society.

OBJECTIVE

We explored venous leg ulcer management from patients' and primary care clinicians' perspective, including assessment, diagnosis, treatment, referral, and health education as outlined in the clinical practice guidelines.

DESIGN

We conducted a qualitative secondary analysis of data obtained from the qualitative face-to-face and telephone interviews with the primary care clinicians and telephone interviews with patients with venous leg ulcers.

SETTING

Clinicians were recruited from urban and rural primary health practices across Victoria, Australia. Patients were recruited from two specialist care wound clinics in Victoria.

PARTICIPANTS

We analysed data from interviews with 66 participants, including 31 patients with venous leg ulcers, 15 general practitioners and 20 practice nurses.

METHODS

Secondary analysis of qualitative data was carried out using thematic analysis. Interview transcripts were coded and analysed for common themes.

RESULTS

We found patients and clinicians reported differing perspectives related to venous leg ulcer management. Patients reported the need for earlier referral to specialist wound care clinics from primary care, emphasizing the need for vascular assessment and compression therapy. Clinicians discussed clinical judgements about when to refer rather than follow guideline recommendations. Clinicians frequently discussed managing venous leg ulcers using only topical dressing treatments, without compression therapy. Patients reported inadequate pain management for wound pain. Meanwhile, clinicians reported that they generally did not discuss wound pain management as part of overall venous leg ulcer management. Clinicians reported patients lacked an understanding about the role of compression in management of and subsequent healing outcomes. Patients stated they wanted more information about how to care for venous leg ulcers and how best to prevent recurrence, and needed more information than was already provided by clinicians. Conversely, clinicians reported less information is given to ensure patients were not overwhelmed with health information.

CONCLUSION

There are discrepancies between what patients want and what clinicians do. These data suggest that patients' preferences are aligned with venous leg ulcer clinical practice guideline recommendations. Greater awareness of the guidelines by health professional may not only reduce discrepancies they may improve health and healing outcomes. Tweetable abstract: Patients and primary care clinicians have different perspectives about venous leg ulcer management.

Pressure injuries among admissions to a hospital in the tropics

We report incidence rates for pressure injuries seen in an acute hospital in Singapore that were classified as Stage 3 or Stage 4. The characteristics of patients and the factors that explain variation in the primary outcome of duration of hospital stay are summarized. Existing data were available from Singapore General Hospital for all admissions from January 2016 to December 2019. Univariable analysis was done and a multivariable Poisson regression model estimated. Incidence rates declined from 4.05 to 3.4 per 1000 admissions in the 48 months between 2016 and 2019. The vast majority were community acquired with 75% in admission from the patients' home. Factors that explain variation in length of stay were, ethnicity; site of injury; community versus healthcare associated; inter-hospital transfer; fracture as reason for admission; and the number of days between admission and assessment of wound by specialist nurse. Stage 3 and 4 injuries arise in a home environment most often and are subsequently managed in acute hospital at high cost. These are novel epidemiological data from a hospital in the tropics where the potential to improve outcomes, implement screening and prevention, and thus increase the performance of health services is strong.

Management of people with venous leg ulcers by Australian general practitioners: An analysis of the national patient-encounter data

Venous Leg Ulcers cost Australia's healthcare system millions yearly, as they are underdiagnosed, and possibly undertreated. Most Venous Leg Ulcers are seen in general practice. However, it is currently unknown as to what treatment actions are most common in these contexts. Understanding how they are managed in these settings can improve healthcare delivery and patient outcomes. Using cross-sectional general practitioner patient encounter data collected April 2006 to March 2016 from the Bettering the Evaluation and Care of Health program, a continuous national study of general practice clinical activity in Australia, we aimed to describe the characteristics of venous leg ulcer management by general practitioners in Australia. Among the 972 100 general practitioner-patient encounters recorded, 3604 (0.34%) involved management of VLU. Male general practitioners managed Venous Leg Ulcers significantly more often than female general practitioners. Most Venous Leg Ulcers were treated via dressings (76%) and/or pharmacological treatments (25.7%), with few patients receiving the best practice treatment of medical compression (2.1%) or referral (4.9%). Patients with new (first visit) Venous Leg Ulcers were more likely to receive pharmacological treatments and to be referred elsewhere, and less likely to receive dressings than patients receiving follow-up care. There appears to be a large gap between best practice guidelines and actual Venous Leg Ulcers treatments, as referrals and appropriate treatment was low. Further longitudinal studies are needed to determine the effectiveness of care for people with Venous Leg Ulcers who are managed by general practitioners.

Patient-reported experience measures are essential to improving quality of care for chronic wounds: An international qualitative study

Traditional quality measures for chronic wounds have focused on objective outcomes that are challenging to risk adjust, lack patient input, and have limited ability to inform quality improvement interventions. Patient-reported experience measures (PREMs) provide information from the patient perspective regarding health care quality and have potential to improve patient-centredness, increase care efficiency, and generate actionable data for quality improvement. The purpose of this study was to understand patient experiences and health care processes that impact quality of care among patients with chronic wounds. Sixty patients at least 18 years of age with various wound aetiologies were recruited from Canada, Denmark, The Netherlands, and the United States as part of a larger phase 1 qualitative study to develop a patient-reported outcome measure for chronic wounds (WOUND-Q). All patients had a chronic wound for at least 3 months, were fluent in their native speaking language, and able to participate in a one-on-one semi-structured interview. Interviews were digitally recorded and transcribed verbatim. Interpretive description was used to identify recurrent themes relating to patient experience and quality of care. We identified five domains (care coordination, establishing/obtaining care, information delivery, patient-provider interaction, and treatment delivery) and 21 sub-domains (access to patient information, interdisciplinary communication, encounter efficiency, provider availability, specialist referral, staff professionalism, travel/convenience, modality, reciprocity, understandability/consistency, accountability, continuity, credentials, rapport, appropriateness, complication management, continuity, environment/setting, equipment and supply needs, expectation, and patient-centred) as potential opportunities to measure and improve quality of care in the chronic wound population. PREMs for chronic wounds represent an important opportunity to engage patients and longitudinally assess quality across clinical settings and providers. Future research should focus on developing PREMs to complement traditional objective and patient-reported outcome measures for chronic wounds.

The outcomes and experience of people receiving community-based nurse-led wound care: A systematic review

AIMS AND OBJECTIVES

To review the literature related to the outcomes and experience of people receiving nurse-led care for chronic wounds in the community.

BACKGROUND

Chronic wounds lead to a poor quality of life and are an economic burden to the Australian healthcare system. A lack of awareness into the significance of chronic wounds leads to limited resources being available to facilitate the provision of evidence-based care. The majority of chronic wounds are managed by nurses in the community, and a better understanding into current models of care is required to inform future practice.

DESIGN

A systematic quantitative literature review.

METHODS

A systematic search was conducted in four electronic databases, and the inclusion criteria were as follows: English language, peer-reviewed, published from 2009-2019 and primary research. The data were compiled into an Excel database for reporting as per the Pickering and Byrne (Higher Education Research & Development, 33, 534.) method of systematic quantitative literature review. This review used the PRISMA checklist. The Mixed Methods Appraisal Tool was used for quality appraisal.

RESULTS

Twelve studies were included in the review. Home nursing care, social community care and nursing within a wound clinic were identified as three types of nurse-led care in the literature. The findings demonstrate that nurse-led care was cost-effective, reported high levels of client satisfaction and contributed to improved wound healing and reduced levels of pain.

CONCLUSIONS

Nurse-led care is a positive experience for people with chronic wounds and leads to better outcomes. The findings suggested a need for further client education and specialised training for healthcare practitioners managing chronic wounds.

RELEVANCE TO CLINICAL PRACTICE

This review demonstrates that nurse-led care for people with chronic wounds in the community is cost-effective and improves client outcomes. Raising awareness into the significance of chronic wounds aims to promote the resources required to facilitate evidence-based care.

First-Line Interactive Wound Dressing Update: A Comprehensive Review of the Evidence

Wound management is a significant and growing issue worldwide. Knowledge of dressing products and clinical expertise in dressing selection are two major components in holistic wound management to ensure evidence-based wound care. With expanding global market of dressing products, there is need to update clinician knowledge of dressing properties in wound care. Optimal wound management depends on accurate patient assessment, wound diagnosis, clinicians’ knowledge of the wound healing process and properties of wound dressings. We conducted a comprehensive review of the physical properties of wound dressing products, including the advantages and disadvantages, indications and contraindications and effectiveness of first-line interactive/bioactive dressing groups commonly used in clinical practice. These include semipermeable films, foams, hydroactives, alginates, hydrofibers, hydrocolloids, and hydrogels. In making decisions regarding dressing product selection, clinicians need to ensure a holistic assessment of patient and wound etiology, and understand dressing properties when making clinical decisions using wound management guidelines to ensure optimal patient outcomes. This review has highlighted there is lack of high quality evidence and the need for future well designed trials.

Vascular assessment in venous leg ulcer diagnostics and management in Australian primary care: Clinician experiences

AIM

In this article, we focus on primary health clinicians' experiences of vascular assessment in venous leg ulcer (VLU) diagnostics and management, including ankle brachial pressure index (ABPI) measurements using Doppler ultrasonography.

METHODS

We conducted semi-structured face-to-face and telephone interviews with general practitioners [15] and practice nurses [20] from primary health care settings in Australia. Twenty-one participants were recruited from practices located in Melbourne metropolitan settings and 14 from rural Victoria. We used the theory driven thematic analysis as a method of data analysis. The Theoretical Domains Framework informed this analysis.

RESULTS

Five domains were identified as relevant, including Environmental Context and Resources, Motivation and Goals, Skills, Knowledge, and Beliefs about Capabilities. Although the Australian and New Zealand clinical practice guideline for prevention and management of venous leg ulcers recommend that vascular assessment is conducted for all patients with suspected VLUs, findings from our study indicate vascular assessments are not routinely performed in many primary care settings. Our study also found that a lack of awareness of clinical practice guidelines among clinicians might be one of the main issues for not following the latest clinical recommendations for vascular assessment in venous leg ulcer diagnostics and wound management practice.

CONCLUSION

We recommend development of theory-informed interventions for clinicians in primary health care settings to optimise VLU management and healing outcomes for patients with VLUs. Implementation and evaluation of these interventions have the potential to reduce the evidence-practice gap in VLU management and optimise healing outcomes.

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.

Barriers and enablers to the use of venous leg ulcer clinical practice guidelines in Australian primary care: A qualitative study using the theoretical domains framework

BACKGROUND

Venous leg ulcers represent the most common chronic wound problem managed in Australian primary care. Despite the prevalence of the condition, there is an evidence-practice gap in both diagnosis and management of venous leg ulcers.

OBJECTIVE

We used the Theoretical Domains Framework to identify barriers and enablers perceived by primary care practitioners in implementing venous leg ulcer guidelines in clinical practice.

DESIGN

We collected data to explore the experiences of practice nurses and general practitioners related to their use of clinical practice guidelines in management of venous leg ulcers.

SETTING(S)

We recruited participants from primary care settings located in metropolitan and rural areas across Victoria, Australia.

PARTICIPANTS

We recruited general practitioners (15) and practice nurses (20).

METHODS

We conducted 35 semi-structured face-to-face and telephone interviews. Content analysis of health practitioners' statements was performed and barriers to implementing clinical practice guidelines were mapped across the Theoretical Domains Framework theoretical domains.

RESULTS

Six main domains from the Theoretical Domains Framework (Environmental context and resources, Knowledge, Skills, Social influences, Social/Professional Role and Identity and Belief about Capabilities) best explained these barriers and enablers. Many participants were not aware of venous leg ulcer clinical practice guidelines. Those that were aware, stated that finding and accessing guidelines was challenging and most participants relied on other sources of information. Venous leg ulcer management was greatly influenced by professional experience and suggestions from colleagues. Other barriers included busy clinical practice, absence of handheld Doppler ultrasonography, insufficient skills and a lack of confidence related to the use of technology to rule out arterial involvement prior to compression application, a particular skill related to venous leg ulcer management that will impact on healing outcomes.

CONCLUSIONS

We identified a number of barriers and the lack of enablers that influence the uptake of venous leg ulcer clinical practice guidelines in primary care. This paper adds a theoretically sound, systematic approach for understanding and addressing the behaviour change required to improve translation of venous leg ulcer clinical practice guidelines in clinical practice. Tweetable abstract: The need to optimise venous leg ulcer clinical practice guidelines (CPG) has never been greater as the current estimate of health cost is AUD3billion and increasing due to rising epidemics of diabetes and obesity. We found most primary care health practitioners are unaware of CPG and this will impact on health and healing outcomes in Australian primary care.

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.

Randomised controlled trials as part of clinical care: A seven-step routinisation framework proposal

Evidence translation in wound care relies on the need for evidence generation. Clinical practice may generate evidence only if evidence-generating research projects, such as randomised controlled trials (RCTs), became routinised in clinical settings. The aim of this study was to identify optimal trial-related practices to routinise trial-related activities in Melbourne-located wound clinics as reported by clinicians and researchers. We conducted a secondary analysis of the available data on how to routinise RCTs in clinical care, with a focus on enablers and suggestions provided by the participants during face-to-face and telephone interviews. Data were obtained from a qualitative observational study nested within a randomised, double-blinded, placebo-controlled trial on clinical effectiveness of aspirin as an adjunct to compression therapy in healing chronic venous leg ulcers (ASPiVLU). We developed a seven-step Routinisation of Trials in Clinical Care Framework. These steps include: (1) pre-trial clinical site assessment, (2) optimising pre-recruitment arrangements, (3) developing and updating trial-related skills, (4) embedding RCT recruitment as part of routine clinical care, (5) promoting teamwork and trial-related collaboration, (6) addressing trial-related financial issues, and (7) communicating trial results to clinicians.

Cost-effectiveness analysis of an innovative model of care for chronic wounds patients

Current provision of services for the care of chronic wounds in Australia is disjointed and costly. There is large variability in the way that services are provided, and little evidence regarding the cost-effectiveness of a specialist model of care for treatment and management. A decision-analytic model to evaluate the cost-effectiveness of a specialist wound care clinic as compared to usual care for chronic wounds is presented. We use retrospective and prospective data from a cohort of patients as well as information from administrative databases and published literature. Our results show specialist wound clinics are cost-effective for the management of chronic wounds. On average, specialist clinics were $3,947 cheaper than usual clinics and resulted in a quality adjusted life year gain of 0.04 per patient, per year. Specialist clinics were the best option under multiple scenarios including a different cost perspective and when the cost of a hospital admission was reduced. Current models of care are inefficient and represent low value care, and specialist wound clinics represent a good investment compared to current approaches for the management of chronic wounds in Australia.

Health benefits of an innovative model of care for chronic wounds patients in Queensland

Wound management in Australia suffers from a lack of adequate coordination and communication between sectors that impacts patient outcomes and costs. Wound Innovations is a specialist service comprising of a transdisciplinary team that aims to streamline and improve patient care and outcomes. We compared patient experiences and outcomes prior to accessing this specialist service, and the 3 months following their enrolment at the clinic. Information on patient experiences, wound history, and outcomes was collected through interviews and a review of medical records for the 12 months prior to enrolment at the clinic. Wound progress, quality of life (QoL) outcomes, and service use were tracked during the 3-month prospective phase. A sample of 29 participants was recruited. 40% healed completely by 3 months, with the average time to healing being 8 weeks. The average QoL score at baseline was 0.69 (from a score of 1, being best health imaginable). At 3 months, the average QoL score increased significantly to 0.84 (P ≤0.001). On average, participants attended the clinic 4.6 times. The average decrease in wound size was 85.4% (95% CI [75.7%, 95%]). Accessing wound care treatment at a specialist, multidisciplinary wound clinic leads to an increase in QoL and access to consistent evidence-based practices.

Measuring costs and quality of life for venous leg ulcers

Venous leg ulcers (VLUs) result in substantial economic costs and reduced quality of life (QoL); however, there are few Australian cost estimates, especially using patient-level data. We measured community-setting VLU management costs and the impact on the QoL of affected individuals. VLU patients were recruited from a specialist wound clinic, an outpatient clinic, and two community care clinics in Queensland. Cost data were collected at the baseline visit. QoL (EQ-5D-5L) and wound status data were collected at baseline, 1, 3, and 6 months. Patients were classified into guideline-based/optimal care and usual care groups. Average weekly costs per patient were statistically significantly different between the usual care and optimal care groups-$214.61 and $294.72, respectively (P = 0.04). Baseline average QoL score for an unhealed ulcer was significantly higher in the optimal care group compared with usual care (P = 0.025). Time to healing differed between the usual care group and the optimal care group (P = 0.04), with averages of 3.9 and 2.7 months, respectively. These findings increase the understanding of the costs, QoL, and healing outcomes of VLU care. Higher optimal care costs may be offset by faster time to healing. This study provides data to inform an economic evaluation of guideline-based care for VLUs.

Economic Evaluations of Guideline-Based Care for Chronic Wounds: a Systematic Review

OBJECTIVES

The aim of this study was to review all published economic evaluations of guideline-based care for chronic wounds and to assess how useful these studies are for decision making in health services.

METHODS

Embase, PubMed, Scopus, Health Technology Assessment (HTA) and National Health Service Economic Evaluation Database (NHS EED) were searched on April 16th, 2018. We included studies that evaluated the economic impact and health outcomes associated with implementing evidence-based guidelines as a bundle of care for the prevention and/or treatment of chronic wounds. Information was extracted from each eligible study and organized by the type of chronic wound. The quality of published economic evaluation studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS).

RESULTS

A total of 24 economic evaluation studies met the inclusion criteria, of which 12 applied decision analytic models. The compliance with the CHEERS checklist ranged between 43 and 83%.

LIMITATIONS

We may have missed some economic evaluation studies despite the use of broad search terms. The quality assessment was conducted based on judgment. Using the CHEERS checklist may reflect the way evaluations were reported rather than conducted.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

We found that guideline-based care may be cost-saving or cost-effective in most circumstances. The quality and usefulness of reviewed studies for decision making were variable. Better information and higher-quality economic evaluations will increase decision makers' confidence to promote guideline-based care.

Cost-effectiveness analysis of guideline-based optimal care for venous leg ulcers in Australia

BACKGROUND

Venous leg ulcers (VLUs) are expensive to treat and impair quality of life of affected individuals. Although improved healing and reduced recurrence rates have been observed following the introduction of evidence-based guidelines, a significant evidence-practice gap exists. Compression is the recommended first-line therapy for treatment of VLUs but unlike many other developed countries, the Australian health system does not subsidise compression therapy. The objective of this study is to estimate the cost-effectiveness of guideline-based care for VLUs that includes public sector reimbursement for compression therapy for affected individuals in Australia.

METHODS

A Markov model was designed to simulate the progression of VLU for patients receiving guideline-based optimal prevention and treatment, with reimbursement for compression therapy, and then compared to usual care in each State and Territory in Australia. Model inputs were derived from published literature, expert opinion, and government documents. The primary outcomes were changes to costs and health outcomes from a decision to implement guideline-based optimal care compared with the continuation of usual care. Sensitivity analyses were performed to test the robustness of model results.

RESULTS

Guideline-based optimal care incurred lower total costs and improved quality of life of patients in all States and Territories in Australia regardless of the health service provider. We estimated that providing compression therapy products to affected individuals would cost the health system an additional AUD 270 million over 5 years but would result in cost savings of about AUD 1.4 billion to the health system over the same period. An evaluation of unfavourable values for key model parameters revealed a wide margin of confidence to support the findings.

CONCLUSIONS

This study shows that guideline-based optimal care would be a cost-effective and cost-saving strategy to manage VLUs in Australia. Results from this study support wider adoption of guideline-based care for VLUs and the reimbursement of compression therapy. Other countries that face similar issues may benefit from investing in guideline-based wound care.

Evaluation of a multifactorial approach to reduce the prevalence of pressure injuries in regional Australian acute inpatient care settings

The aim of the study was to compare the changes in the prevalence of pressure injuries from 2008 to 2014 in relation to staff behaviour in acute/subacute inpatient care settings. In 2008, the large regional health district Hunter New England Local Health District implemented an initiative called the Crystal Model which resulted in changes in their policy and an e-learning education program for all nursing staff. A retrospective cross sectional study compared data from the 2008, 2010 and 2014 point prevalence surveys of PI in acute services. These were collected as part of an annual pressure injury prevention and management quality audit for adult inpatients. The total number of participants included 1407 participants in 2008, 1331 participants in 2010 and 1199 participants in 2014. From 2008 to 2014 there was a 15.7% decrease in percentage of patients with hospital-acquired pressure injuries and the percentages of each stage of pressure of injury 1-4 decreased. From 2008 to 2014 the completion and documentation of risk assessment, the documentation of repositioning and the implementation of pressure-relieving equipment increased. A multifactorial model can reduce the prevalence of pressure injuries in acute inpatient settings. The theories of knowledge translation and the modified Theory of Planned Behaviour can be utilised to analyse changes in health professionals habituated pressure injury prevention practice.

Impact of UK NICE clinical guidelines 168 on referrals to a specialist academic leg ulcer service

Background

Leg ulcers are a common cause of morbidity and disability and result in significant health and social care expenditure. The UK National Institute for Health and Care Excellence (NICE) Clinical Guideline (CG)168, published in July 2013, sought to improve care of patients with leg ulcers, recommending that patients with a break in the skin below the knee that had not healed within two weeks be referred to a specialist vascular service for diagnosis and management.

Aim

Determine the impact of CG168 on referrals to a leg ulcer service.

Methods

Patients referred with leg ulceration during an 18-month period prior to CG168 (January 2012–June 2013) and an 18-month period commencing six months after (January 2014–June 2015) publication of CG168 were compared.

Results

There was a two-fold increase in referrals (181 patients, 220 legs vs. 385 patients, 453 legs) but no change in mean age, gender or median-duration of ulcer at referral (16.6 vs. 16.2 weeks). Mean-time from referral to specialist appointment increased (4.8 vs. 6 weeks, p = 0.0001), as did legs with superficial venous insufficiency (SVI) (36% vs. 44%, p = 0.05). There was a trend towards more SVI endovenous interventions (32% vs. 39%, p = 0.271) with an increase in endothermal (2 vs. 32 legs, p = 0.001) but no change in sclerotherapy (24 vs. 51 legs) treatments. In both groups, 62% legs had compression. There was a reduction in legs treated conservatively with simple dressings (26% vs. 15%, p = 0.0006).

Conclusions

Since CG168, there has been a considerable increase in leg ulcer referrals. However, patients are still not referred until ulceration has been present for many months. Although many ulcers are multi-factorial and the mainstay of treatment remains compression, there has been an increase in SVI endovenous intervention. Further efforts are required to persuade community practitioners to refer patients earlier, to educate patients and encourage further investment in chronically underfunded leg ulcer services.

Effect of low-level laser therapy on angiogenesis and matrix metalloproteinase-2 immunoexpression in wound repair

Low-level laser therapy (LLLT) induces anti-inflammatory and angiogenic activities in wound healing. However, the mechanism of action and optimal parameters require further clarification. In this study, we investigated the effects of LLLT on wound healing matrix metalloproteinase (MMP)-2 immunoexpression and angiogenic processes. Twenty female Wistar rats were randomly divided into four groups (n = 5) according to the treatments as follows. CG7 and CG14 were control groups at days 7 and 14, respectively, which received physiological saline (0.9 % NaCl daily). LG7 and LG14 were laser therapy groups at days 7 and 14, respectively, which received two (LG7) or four (LG14) LLLT applications (40 mW; 660 nm; 4 J/cm²). A dorsal skin sample in the wound area (measuring 2 cm²) was removed after the experimental period, and then the animals were euthanized. The specimens were processed for qualitative and quantitative histological analyses and measurement of MMP-2 expression in the dermis and epidermis. A persistent crust and moderate number of inflammatory cells were found in CG7 and CG14 groups. In the LG14 group, wounds demonstrated complete re-epithelization at the remodeling phase. Angiogenesis and MMP-2 expression were higher in LLLT-treated groups, particularly the LG14 group, which correlated according to the Spearman correlation test. LLLT improves wound healing by enhancing neocollagenesis, increasing the amount of new vessels formed in the tissue (neoangiogenesis), and modulating MMP-2 expression. Epidermal overexpression of MMP-2 was correlated to angiogenic processes.

A cost-effectiveness analysis of optimal care for diabetic foot ulcers in Australia

In addition to affecting quality of life, diabetic foot ulcers (DFUs) impose an economic burden on both patients and the health system. This study developed a Markov model to analyse the cost-effectiveness of implementing optimal care in comparison with the continuation of usual care for diabetic patients at high risk of DFUs in the Australian setting. The model results demonstrated overall 5-year cost savings (AUD 9100·11 for those aged 35-54, $9391·60 for those aged 55-74 and $12 394·97 for those aged 75 or older) and improved health benefits measured in quality-adjusted life years (QALYs) (0·13 QALYs, 0·13 QALYs and 0·16 QALYs, respectively) for high-risk patients receiving optimal care for DFUs compared with usual care. Total cost savings for Australia were estimated at AUD 2·7 billion over 5 years. Probabilistic sensitivity analysis showed that optimal care always had a higher probability of costing less and generating more health benefits. This study provides important evidence to inform Australian policy decisions on the efficient use of health resources and supports the implementation of evidence-based optimal care in Australia. Furthermore, this information is of great importance for comparable developed countries that could reap similar benefits from investing in these well-known evidence-based strategies.
