Seng L, Drovandi A, Fernando ME, Golledge J. Opinions about the most appropriate surgical management of diabetes-related foot infection: a cross-sectional survey. J Foot Ankle Res 2022; 15:18. [PMID: 35232476 PMCID: PMC8889647 DOI: 10.1186/s13047-022-00523-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 02/21/2022] [Indexed: 11/18/2022] Open
Abstract
Background There is a lack of high quality evidence to guide the optimal management of diabetes-related foot infection, particularly in cases of severe diabetes-related foot infection and diabetes-related foot osteomyelitis. This study examined the opinions of surgeons about the preferred management of severe diabetes-related foot infection. Methods Vascular and orthopaedic surgeons in Australia and New Zealand were invited to complete an online survey via email. The survey included multi-choice and open-ended questions on clinical management of diabetes-related foot infection. Responses of vascular surgeons and orthopaedic surgeons were compared using non-parametric statistical tests. Open-text responses were examined using inductive content analysis. Results 29 vascular and 20 orthopaedic surgeons completed the survey. One-third (28.6%) used best-practice guidelines to assist in decisions about foot infection management. Areas for guideline improvement identified included more specific advice regarding the indications for available treatments, more recommendations about non-surgical patient management and advice on how management can be varied in regions with limited health service resource. The probe-to-bone test and magnetic resonance imaging were the preferred methods of diagnosing osteomyelitis. Approximately half (51.2%) of respondents indicated piperacillin combined with tazobactam as the preferred antibiotic choice for empirical treatment of severe diabetes-related foot infection. Negative pressure wound therapy was the most common way of managing a wound following debridement. All vascular surgeons (100%) made revascularisation decisions based on the severity of ischemia while most orthopaedic surgeons (66.7%) were likely to refer to vascular surgeons to make revascularisation decisions. Vascular surgeons preferred using wound swabs while orthopaedic surgeons favoured tissue or bone biopsies to determine the choice of antibiotic. Respondents perceived a moderate variation in management decisions between specialists and supported the need for randomised controlled trials to test different management pathways. Conclusions Most vascular and orthopaedic surgeons do not use best-practice guidelines to assist in decisions about management of diabetes-related foot infection. Vascular and orthopaedic surgeons appear to have different preferences for wound sampling to determine choice of antibiotic. There is a need for higher quality evidence to clarify best practice for managing diabetes-related foot infection.

COVER: A Curriculum in the Management of Soft Tissue Injury and Infection for Junior Surgery Residents. J Grad Med Educ 2021; 13:95-102. [PMID: 33680307 PMCID: PMC7901621 DOI: 10.4300/jgme-d-20-00278.1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/18/2020] [Accepted: 08/29/2020] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND While wound management is a common task for practicing surgeons, there is a paucity of dedicated education on soft tissue management during residency training. OBJECTIVE The COVER (Causes of soft tissue injury, Obstacles to closure, Vacuums and stitches, Epithelialization, Rationale for wound care) curriculum was developed to engage junior surgery residents in the management of soft tissue injury and infection. METHODS Junior surgery residents participated in the COVER lab during academic years 2018-2020. Residents applied appropriate surgical management and wound care to cadaveric models of soft tissue injury and infection. Assessments included a pre-/post-curriculum and pre-/post-lab multiple choice questionnaire and survey. RESULTS All eligible residents (n = 45, 27) participated in the COVER lab for both academic years. Postgraduate year (PGY)-1s, PGY-2s, and PGY-3s showed improvement in wound management knowledge with an average increase in score of 17%, 8%, and 18%, respectively. They also showed a change in their self-reported perceived ability to achieve primary soft tissue closure with confidence levels 22%, 20%, and 16%, respectively. This was again seen in perceived ability to manage soft tissue injuries and infections (28%, 28%, and 23%, respectively). There was a significant increase in performing new wound management skills (PGY-1 mean 51.3%, PGY-2 33.5%, PGY-3 20%; ANOVA, P = .0001). CONCLUSIONS The COVER curriculum provides a systematic approach to soft tissue injury and infection. Residents showed a significant increase in both soft tissue knowledge as well as confidence in ability to perform wound management.

Abstract
Objective: Chronic wounds represent a highly prevalent but little recognized condition with substantial implications for patients and payers. While better wound care products and treatment modalities are known to improve healing rates, they are inconsistently used in real-world practice. Predicting healing rates of chronic wounds and comparing to actual rates could be used to detect and reward better quality of care. We developed a prediction model for chronic wound healing. Approach: We analyzed electronic medical records (EMRs) for 620,356 chronic wounds of various etiologies in 261,398 patients from 532 wound care clinics in the United States. Patient-level and wound-level parameters influencing wound healing were identified from prior research and clinician input. Logistic regression and classification tree models to predict the probability of wound healing within 12 weeks were developed using a random sample of 70% of the wounds and validated in the remaining data. Results: A total of 365,659 (58.9%) wounds were healed by week 12. The logistic and classification tree models predicted healing with an area under the curve of 0.712 and 0.717, respectively. Wound-level characteristics, such as location, area, depth, and etiology, were more powerful predictors than patient demographics and comorbidities. Innovation: The probability of wound healing can be predicted with reasonable accuracy in real-world data from EMRs. Conclusion: The resulting severity adjustment model can become the basis for applications like quality measure development, research into clinical practice and performance-based payment.

Clinical evaluation of the efficacy and safety of a medical device in various forms containing Triticum vulgare for the treatment of venous leg ulcers - a randomized pilot study. DRUG DESIGN DEVELOPMENT AND THERAPY 2015; 9:2787-92.

Abstract
This study was carried out to assess the efficacy and tolerability of the topical application of an aqueous extract of Triticum vulgare (TV) in different vehicles (cream, impregnated gauzes, foam, hydrogel, and dressing gel) for the treatment of venous lower leg ulcers. Fifty patients were randomized to receive one of the five investigational vehicles. Treatment was performed up to complete healing or to a maximum of 29 days. The wound size reduction from baseline was the primary efficacy variable, which was measured by means of a noninvasive laser scanner instrument for wound assessment. In all groups, apart from the foam group, a similar trend toward the reduction of the surface area was observed. The cream showed the greatest effect on the mean reduction of the lesion size. At last visit, six ulcers were healed: two in the cream group, three in the gauze group, and one in the dressing gel group. In the patients treated with the cream, the gauzes, the hydrogel, and the dressing gel, the reduction of lesion size was 40%–50%; the reduction was smaller in the foam group. No impact in terms of age on the healing process was found. The Total Symptoms Score decreased in all groups during the study; a greater efficacy in terms of signs/symptoms was observed in the patients treated with the gauzes. In the dressing gel group, one patient had an infection of the wound after 3 weeks of treatment and 2 of colonization, leading to a systemic antibiotic treatment. The events were judged as nonrelated to the device used. On the basis of the results, it could be argued that the medical device may be useful in the treatment of chronic venous ulcers.

Abstract
BACKGROUND Costs of chronic wound care are significant, but systematic reviews of cost-effectiveness studies regarding guideline-based or strategic interventions are scarce. OBJECTIVES Our objectives were to assess/compare the cost effectiveness of new interventions/systems designed to improve the prevention/treatment of chronic wounds in adult populations against current care and provide decision makers with information on which to base future interventions for chronic wound management. DATA SOURCES Data sources included PubMed, Scopus, HTA, and NHS EED. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS We included comparative health economic evaluations of interventions published in English designed to prevent or treat adult chronic wounds that were guideline-based or strategic in nature and from which an incremental cost-effectiveness ratio or incremental net health benefit was reported or could be calculated. STUDY APPRAISAL AND SYNTHESIS METHODS Study and model characteristics and outcomes were extracted into pre-designed tables. Quality assessment of studies was based on literature-reported methods. Studies were assigned strength of evidence ratings and recommendation level for decision makers. RESULTS A total of 16 health economic evaluations were included, of which ten were trial based and six were wholly model based. Only three studies had high, and five studies moderate, strength of evidence and were recommended for decision makers. All studies had some shortcomings regarding time horizon, costs, effectiveness units, and methodological reporting. Two studies had major flaws. LIMITATIONS Limitations include missed studies published in non-English languages or not cited in searched databases; judgment bias in assessing studies. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS Few well conducted cost-effectiveness studies exist to guide decision makers regarding guideline-based or strategic interventions for chronic wounds.

Abstract
Using data from a national wound-specific electronic medical record (WoundExpert, Net Health, Pittsburgh, PA), we compared the effectiveness of a bilayered living cellular construct (BLCC) and an acellular porcine small intestine submucosa collagen dressing (SIS) for the treatment of venous leg ulcer. Data from 1,489 patients with 1,801 refractory venous leg ulcers (as defined by failure to have >40% reduction in size in the 4 weeks prior to treatment) with surface areas between 1 and 150 cm(2) in size, treated between July 2009 and July 2012 at 158 wound care facilities across the US were analyzed. Patient baseline demographics and wound characteristics were comparable between groups. Kaplan-Meier-derived estimates of wound closure for BLCC (1,451 wounds) was significantly greater (p = 0.01, log-rank test) by weeks 12 (31% vs. 26%), 24 (50% vs. 41%), and 36 (61% vs. 46%), respectively, compared with SIS (350 wounds). BLCC treatment reduced the median time to wound closure by 44%, achieving healing 19 weeks sooner (24 vs. 43 weeks, p = 0.01, log-rank test). Treatment with BLCC increased the probability of healing by 29% compared with porcine SIS dressing (hazard ratio = 1.29 [95% confidence interval 1.06, 1.56], p = 0.01).

Abstract
INTRODUCTION Clinical practice guidelines can improve healthcare processes and patient outcomes, but are often of low quality. Guideline appraisal tools aim to help potential guideline users in assessing guideline quality. We conducted a systematic review of publications describing guideline appraisal tools in order to identify and compare existing tools. METHODS Among others we searched MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews from 1995 to May 2011 for relevant primary and secondary publications. We also handsearched the reference lists of relevant publications. On the basis of the available literature we firstly generated 34 items to be used in the comparison of appraisal tools and grouped them into thirteen quality dimensions. We then extracted formal characteristics as well as questions and statements of the appraisal tools and assigned them to the items. RESULTS We identified 40 different appraisal tools. They covered between three and thirteen of the thirteen possible quality dimensions and between three and 29 of the possible 34 items. The main focus of the appraisal tools were the quality dimensions "evaluation of evidence" (mentioned in 35 tools; 88%), "presentation of guideline content" (34 tools; 85%), "transferability" (33 tools; 83%), "independence" (32 tools; 80%), "scope" (30 tools; 75%), and "information retrieval" (29 tools; 73%). The quality dimensions "consideration of different perspectives" and "dissemination, implementation and evaluation of the guideline" were covered by only twenty (50%) and eighteen tools (45%) respectively. CONCLUSIONS Most guideline appraisal tools assess whether the literature search and the evaluation, synthesis and presentation of the evidence in guidelines follow the principles of evidence-based medicine. Although conflicts of interest and norms and values of guideline developers, as well as patient involvement, affect the trustworthiness of guidelines, they are currently insufficiently considered. Greater focus should be placed on these issues in the further development of guideline appraisal tools.

Abstract
OBJECTIVE To describe the role of health economics (HE) in wound care in relation to coverage and reimbursement. APPROACH Narrative description of key concepts with supporting references. RESULTS The process of approval or clearance of wound care products within the U.S. regulatory framework often causes lack of high level of evidence regarding clinical outcomes. There is also a paucity of HE information and great reluctance to use such information (when it is available) by insurers and Centers for Medicare and Medicaid, as well as other health-care agencies. Cost-effectiveness (CE) studies are the most common type of HE study in wound care, and the most common outcomes are incremental CE ratios (ICERs). Interpretation of ICERs requires considerable judgment when results are not obvious and is hampered by lack of contemporary and useful benchmarks. While many lessons have been learned in applying CE to coverage and reimbursement decisions in other western countries-including transparency of decision-making and involvement of patients-there is still a major aversion to using CE in the United States Applying CE to basic wound care and advanced therapeutics has the potential to decrease the costs of wound healing considerably. INNOVATION AND CONCLUSIONS Many CE approaches, including modeling, provide sufficiently detailed information that decision-makers can make informed decisions about wound care products in regard to coverage and reimbursement. The reluctance to use CE information in the United States, however, is likely to contribute heavily to the ever-increasing costs in wound care.
