The impact of the multidisciplinary team in the management of individuals with diabetic foot ulcers: a systematic review

The frequency of neuropathy and predictive parameters in prediabetic cases from Turkiye

INTRODUCTION

Diabetic sensorimotor peripheral neuropathy causes patients to have foot injuries without realizing it. This condition may progress to diabetic foot ulcer; infections can include osteomyelitis and lower limb amputations. Managing diabetes and screening diabetic neuropathy is crucial to reducing patient mortality, quality of life, functionality, and the cost burden of complications to the healthcare system. We aim to contribute to the literature by comparing diagnostic methods and examining parameters that can predict neuropathy early.

MATERIAL AND METHODS

A total of 108 patients with a neuropathy score Douleur Neuropathique-4 (DN-4) above 4, 54 with known diabetes, and 54 with prediabetes were included. Fasting plasma glucose, oral glucose tolerance test, hemoglobin A1c (HbA1c), LDL-cholesterol, HDL-cholesterol, triglyceride, uric acid, vitamin B12, folic acid, creatinine, and complete urinalysis was performed on 108 patients included. Afterward, a monofilament test, tuning fork test, and electromyography were performed by the neurologist to prove neuropathy.

RESULTS

The frequency of neuropathy in the prediabetes group was found to be 0.40 ± 0.49 % using EMG. This rate is 0.71 ± 0.45 % for diabetic neuropathy. The difference is statistically significant (p = 0.001) in the prediabetic group, the neuropathy score (DN-4 score) was 5.1 ± 0.9, the tuning fork test positivity was 0.18 ± 0.39, and p = 0.001 was statistically significant compared to the diabetic group. Also, in the monofilament test, the rate of neuropathy in the prediabetes group was again statistically significant with 0.68 ± 0.47 (p = 0.027). Total cholesterol (185.1 ± 21.8, p = 0.003), high uric acid (5.11 ± 1.27, p = 0.003), and low folic acid (4.5 ± 1.05, p = 0.026) are found to be statistically significant between diabetic and prediabetic groups.

DISCUSSION AND CONCLUSION

In diagnosing neuropathy, monofilament, and diapason testing can be used in the clinical setting, and they have been found to be successful tests in the diagnosis of neuropathy. Also, our analysis indicates the relationship between low folic acid, high total cholesterol/uric acid levels, and prediabetic neuropathy. The role of intervening blood levels of those factors with medications in preventing neuropathy is unclear. We recommend further investigating all the patient's dietary habits to find possible risk factors, as well as investigating patients with low folic acid and high total cholesterol/ uric acid levels much more cautiously.

RECOMMENDATION

Neuropathy should be screened in prediabetic and diabetic patients, and possible risk factors should be assessed periodically.

Multidisciplinary Approach to Midfoot Charcot Neuro-Osteoarthropathy: A Case Series

BackgroundIn Charcot neuro-osteoarthropathy (CNO), deformity-induced ulcers significantly increase the risk of amputation. Reconstructive foot surgery (RFS) is essential to prevent this, but peripheral artery disease (PAD) and diabetes increase complication risks.MethodsAll patients from a single center treated with RFS for midfoot CNO between 2019 and 2023 were included. Treatment followed a multidisciplinary protocol aimed at optimizing 4 factors: hyperglycemia, infection, pressure, and arterial blood flow.ResultsSeventeen patients were included (mean follow-up 20 months). Sixteen patients (94%) achieved an ulcer-free, plantigrade foot. No amputations were performed. Fifteen patients (88%) were diabetic, 67% of whom had elevated HbA1c levels, and 80% of these normalized after treatment. Four patients had PAD (24%), of whom 2 required revascularization. Deep infections occurred in 4 (24%) cases, and 6 (35%) required additional surgery.ConclusionsUlcer-free and good functional outcomes can be achieved, and amputation prevented, in patients with midfoot CNO provided they are treated by a multidisciplinary team.Level of Evidence:Level IV, case series.

Narrative review of comprehensive management strategies for diabetic retinopathy: interdisciplinary approaches and future perspectives

This review examines the epidemiological trends, pathophysiologic mechanisms, and current and future therapeutic strategies for diabetic retinopathy (DR), focusing on innovative management countermeasures in the face of this global public health challenge. As the number of patients with diabetes continues to increase, DR, as one of its major complications, poses a significant threat to global visual health. This review not only summarises the latest advances in personalised treatment and emerging therapeutic modalities (such as anti-vascular endothelial growth factor therapy, laser treatment, surgical procedures and cutting-edge gene and stem cell therapies) but also emphasises the revolutionary potential of telemedicine technologies and digital health platforms to improve DR screening and adherence among people with diabetes. We show how these technological innovations, especially in resource-limited settings, can achieve early diagnosis and effective treatment, thereby significantly reducing the public health burden of DR. In addition, this article highlights the critical role of interdisciplinary teamwork in optimising the comprehensive management of DR, involving close collaboration among physicians, researchers, patient education specialists and policy-makers, as well as the importance of implementing these innovative solutions through societal engagement and policy support. By highlighting these innovative strategies and their specific impact on improving public health practices, this review offers new perspectives and strategies for the future management of DR, with the goal of promoting the prevention, diagnosis and treatment of DR worldwide, improving patient prognosis and enhancing quality of life.

Temporal and regional trends in Canada for the epidemiology and management of diabetic foot ulcers

OBJECTIVE

Diabetic foot ulcers (DFUs) are a common downstream consequence of diabetes and pose significant concern to the health of affected individuals. There are currently limited data available that detail the epidemiology and inpatient burden of DFUs in Canada. This study aims to provide updated data on the epidemiological and economic burden of DFUs in Canada between 2015 and 2019.

METHOD

Using the Canadian Institute for Health Information Patient Cost Estimator the authors estimated, as the primary outcome, the number of DFU inpatient cases in Canada, the associated financial burden of these admissions on the Canadian healthcare system, physician compensation, and average patient length of hospitalisation. This analysis covered 12 Canadian jurisdictions and was stratified by age, sex, province and geographical region. The secondary outcome was to highlight temporal trends in the public health burden of DFUs by computing the average annual percentage change (AAPC; the weighted average of several annual percentage changes over multiple years) using Joinpoint (Surveillance Research Program National Cancer Institute, US) regression analysis.

RESULTS

The total number of cases, average length of hospitalisation and physician costs across Canada were highest for patients over ≥60 years of age. By region, the total number of cases and standardised physician costs were highest in Central Canada, followed by Western Canada, and subsequently Eastern and Northern Canada. In 2019, there were >1800 patients with DFUs admitted to Canadian acute care hospitals. Despite having the lowest number of inpatient admissions, Northern Canada had the highest associated inpatient costs, followed by Central, then Western and, lastly, Eastern Canada. Overall, mean inpatient costs remained stable over time across all age groups (AAPC 0.61; 95% confidence interval: -1.87-3.15), with an average cost of >$10,000 CAD per case. Average physician cost across all jurisdictions was approximately $1000 CAD per case, with the mean hospitalisation time being nine days.

CONCLUSION

The findings of this study emphasise the dynamic nature of the economic and epidemiological DFU burden in Canada, underscoring the need for targeted interventions, multidisciplinary care and evidence-based resource allocation for the optimal management of diabetes and DFUs.

Surgical Management of Complex Ankle Fractures in Patients with Diabetes: A National Retrospective Multicentre Study

Objectives: Patients with ankle fractures associated with diabetes experience more complications following standard open reduction-internal fixation (ORIF) than those without diabetes. Augmented fixation strategies, namely extended ORIF and hindfoot nails (HFNs), may offer better results and early weightbearing in this group. The aim of this study was to define the population of patients with diabetes undergoing primary fixation for ankle fractures. Secondarily, we aimed to assess the utilisation of standard and augmented strategies and the effect of these choices on surgical outcomes, including early post-operative weightbearing and surgical complications. Methods: A national multicentre retrospective cohort study was conducted between January and June 2019 in 56 centres (10 major trauma centres and 46 trauma units) in the United Kingdom; 1360 patients with specifically defined complex ankle fractures were enrolled. The patients' demographics, fixation choices and surgical and functional outcomes were recorded. Statistical analysis was performed to compare high-risk patients with and without diabetes. Results: There were 316 patients in the diabetes cohort with a mean age of 63.9 yrs (vs. 49.3 yrs. in the non-diabetes cohort), and a greater frailty score > 4 (24% vs. 14% (non-diabetes cohort) (p < 0.03)); 7.5% had documented neuropathy. In the diabetes cohort, 79.7% underwent standard ORIF, 7.1% extended ORIF and 10.2% an HFN, compared to 87.7%, 3.0% and 10.3% in the non-diabetes cohort. Surgical wound complications after standard-ORIF were higher in the diabetes cohort (15.1% vs. 8.7%) (p < 0.02), but patients with diabetes who underwent augmented techniques showed little difference in surgical outcomes/complications compared to non-diabetes patients, even though early-weightbearing rates were greater than for standard-ORIF. Conclusions: Ankle fractures in diabetes occur in older, frailer patients, whilst lower-than-expected neuropathy rates suggest a need for improved assessment. Augmented surgical techniques may allow earlier weightbearing without increasing complications, in keeping with modern guidelines in ankle fracture management.

Definitive single-stage surgery for treating diabetic foot osteomyelitis: a protocolized pathway including antibiotic bone graft substitute use

BACKGROUND

Diabetic foot ulcers (DFUs) are a challenging complication of diabetes mellitus, often leading to poor clinical outcomes and significant socioeconomic burdens. We evaluated the effectiveness of a definitive single-stage protocolized surgical management pathway, including the use of local antibiotic bone graft substitute, for the treatment of infected DFUs with associated osteomyelitis.

METHODS

A retrospective cohort study was conducted. Medical records were extracted (from January 2017 to December 2020) to establish a database consisting of patients who underwent surgical intervention for the treatment of an infected DFU with osteomyelitis. Patients were divided into conventional (control) and protocolized (intervention) surgical groups depending on the treatment received. Clinical outcomes were assessed over a 12-month follow-up period.

RESULTS

A total of 136 consecutive patients were included (conventional = 33, protocolized = 103). The protocolized group demonstrated a statistically significant reduction in the mean number of operations performed per patient (1.2 vs. 3.5) (P < 0.001) and a shorter accumulative hospital length of stay (12.6 vs. 25.1 days) (P < 0.001) compared to the conventional group. Major amputation rates were significantly lower in the protocolized group (2% vs. 18%) (P < 0.001). Within 12 months of surgical intervention, the protocolized group exhibited an ulcer healing rate of 89%, with a low rate of recurrence (3%).

CONCLUSION

The protocolized surgical pathway, including local antibiotic bone graft substitute use, demonstrated superior outcomes compared to conventional management for the treatment of infected DFUs with osteomyelitis. Further research is needed to evaluate the cost-effectiveness and generalizability of this approach.

The Efficacy of Diabetic Foot Treatment in a "TOSF" Pattern: A Five-Year Retrospective Study

Aim

To evaluate the advantages and problems in the diagnosis and treatment of diabetic foot (DF) patients by analyzing the results of a 5-year follow-up of the organ system based (TOSF) treatment model.

Methods

A retrospective study was conducted in 229 patients with diabetic foot. Chi-square test and rank-sum test were used to analyze the effects of patients' general condition, behavioral and nutritional status, degree of infection (inflammatory markers), comorbidity, diabetic foot grade/classification, and revascularization on readmission rate, amputation rate, all-cause mortality, incidence of other complications, and wound healing time. Logistic regression was used to analyze the risk factors affecting the prognosis of diabetic foot. Kaplan-Meier survival curve was used to analyze the differences in amputation rate and mortality rate at each time point.

Results

This study showed that nutritional status, degree of infection, and revascularization influenced readmission rates. General condition, behavior and nutritional status, degree of infection, Wagner grade and revascularization affect the amputation rate. General conditions, behavioral and nutritional status, degree of infection, comorbidities, classification and revascularization affect the mortality of patients. Age and white blood cell(WBC) count affected the incidence of other complications. Influence of infection degree and Wagner grade and revascularization in patients with wound healing time. Revascularization was an independent protective factor for readmission, amputation, and mortality.Elevated serum inflammatory markers are an independent risk factor for amputation. Hypoproteinemia is an independent risk factor for mortality.

Conclusion

In the "TOSF" diagnosis and treatment pattern, diabetic foot patients have a good prognosis. Special attention should be paid to the screening and revascularization of lower extremity vascular disease in patients with diabetic foot.

Changes in daily nursing needs and self-care capability of people with diabetes after in-hospital treatment for foot complications: A descriptive study

AIM

A limited number of studies discuss the changes in patients' self-care skills and needs for assisted self-care after discharge from in-patient treatment due to diabetes foot ulcer-related complications. The aim of this study was to examine the ability to perform self-care and needs for assisted nursing interventions at hospital discharge, compared to pre-admission, for people with diabetes admitted and treated for foot ulcer-related complications.

DESIGN

Retrospective patient record study.

METHODS

A retrospective assessment was done on the medical records of a total of 134 patients with diabetes consecutively admitted to a specialist in-patient unit due to foot ulcer complications, between 1 November 2017 and 30 August 2018. Data on daily self-care needs and home situations at admission and discharge were recorded.

RESULTS

The median age was 72 years (38-94), 103 (76.9%) were men and 101 (73.7%) had diabetes type 2. The median length of admission was 10 days (2-39). Infection was the most common cause of admission (51%), with severe ischaemia in 6%, and a combination of both in 20% of patients. Surgical treatment was performed in 22% and vascular intervention in 19% of patients. The percentage of patients discharged to their home without assistance was 48.1% compared to 57.5% before admission, discharge to home with assistance was 27.4% versus 22.4% before admission and 9.2% were discharged to short-term nursing accommodation versus 6% before admission. Three patients died during their stay in hospital. The need for help with medications increased from 14.9% of patients at admission to 26.7% at discharge and for mobility assistance from 23.1% to 35.9%. Social services at home were increased in 21.4% of patients at discharge.

Effect of a multidisciplinary team approach in patients with diabetic foot ulcers on major adverse limb events (MALEs): systematic review and meta-analysis for the development of the Italian guidelines for the treatment of diabetic foot syndrome

The treatment of patients with diabetic foot ulcers (DFUs) is extremely complex, requiring a comprehensive approach that involves a variety of different healthcare professionals. Several studies have shown that a multidisciplinary team (MDT) approach is useful to achieve good clinical outcomes, reducing major and minor amputation and increasing the chance of healing. Despite this, the multidisciplinary approach is not always a recognized treatment strategy. The aim of this meta-analysis was to assess the effects of an MDT approach on major adverse limb events, healing, time-to-heal, all-cause mortality, and other clinical outcomes in patients with active DFUs. The present meta-analysis was performed for the purpose of developing Italian guidelines for the treatment of diabetic foot with the support of the Italian Society of Diabetology (Società Italiana di Diabetologia, SID) and the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD). The study was performed using the Grading of Recommendations Assessment, Development, and Evaluation approach. All randomized clinical trials and observational studies, with a duration of at least 26 weeks, which compared the MDT approach with any other organizational strategy in the management of patients with DFUs were considered. Animal studies were excluded. A search of Medline and Embase databases was performed up until the May 1st, 2023. Patients managed by an MDT were reported to have better outcomes in terms of healing, minor and major amputation, and survival in comparison with those managed using other approaches. No data were found on quality of life, returning-to-walking, and emergency admission. Authors concluded that the MDT may be effective in improving outcomes in patients with DFUs.

Developing an interprofessional decision support tool for diabetic foot ulcers management in primary care within the family medicine group model: a Delphi study in Canada

BACKGROUND

Primary care professionals encounter difficulties coordinating the continuum of care between primary care providers and second-line specialists and adhere to practice guidelines pertaining to diabetic foot ulcers management. Family medicine groups are providing primary care services aimed to improve access, interdisciplinary care, coordination and quality of health services, and reduce emergency department visits. Most professionals working in family medicine groups are primary care physicians and registered nurses. The aim of this study was to develop and validate an interprofessional decision support tool to guide the management of diabetic foot ulcers for primary care professionals working within the family medicine group model.

METHODS

A one-page decision tool developed by the research team was validated by an expert panel using a three-round Delphi protocol held between December 2019 and August 2021. The tool includes 43 individual actions and a care pathway from initial presentation to secondary prevention. Data collection was realized with both paper and electronic questionnaires, and answers were compiled in an electronic spreadsheet. Data was analyzed with use of descriptive statistics, and consensus for each item was defined as ≥ 80% agreement.

RESULTS

Experts from 12 pre-identified professions of the diabetic foot ulcer interdisciplinary care team were included, 39 participants out of the 59 invited to first round (66.1%), 34 out of 39 for second (87.2%) and 22 out of 34 for third (64.7%) rounds. All items included in the final version of the decision support tool reached consensus and were deemed clear, relevant and feasible. One or more professionals were identified to be responsible for every action to be taken.

CONCLUSIONS

This study provided a comprehensive decision support tool to guide primary care professionals in the management of diabetic foot ulcers. Implementation and evaluation in the clinical setting will need to be undertaken in the future.

Standards for the development and methodology of the 2023 IWGDF guidelines

AIMS

Diabetes-related foot disease is a major source of patient burden and societal costs. Investing in evidence-based international guidelines on diabetes-related foot disease is important to reduce this burden and costs, provided the guidelines are focused on outcomes important to key stakeholders and are evidence-based and properly implemented.

MATERIALS AND METHODS

The International Working Group on the Diabetic Foot (IWGDF) has published and updated international guidelines since 1999. The 2023 updates were made using the Grading of Recommendations Assessment Development and Evaluation evidence-to-decision framework. This concerns formulating relevant clinical questions and important outcomes, conducting systematic reviews of the literature and meta-analyses where appropriate, completing summary of judgement tables, and writing recommendations that are specific, unambiguous and actionable, along with their transparent rationale.

RESULTS

We herein describe the development of the 2023 IWGDF Guidelines on the prevention and management of diabetes-related foot disease, which consists of seven chapters, each prepared by a separate working group of international experts. These chapters provide guidelines related to diabetes-related foot disease on prevention; classification of diabetes-related foot ulcer, offloading, peripheral artery disease, infection, wound healing interventions, and active Charcot neuro-osteoarthropathy. Based on these seven guidelines, the IWGDF Editorial Board also produced a set of practical guidelines. Each guideline underwent extensive review by the members of the IWGDF Editorial Board as well as independent international experts in each field.

CONCLUSIONS

We believe that the adoption and implementation of the 2023 IWGDF guidelines by healthcare providers, public health agencies, and policymakers will improve the prevention and management of diabetes-related foot disease, and subsequently reduce the worldwide patient and societal burden caused by this disease.

The impact of diabetes on mortality rates after lower extremity amputation

OBJECTIVE

To assess the impact of diabetes, amputation level, sex and age on mortality rates after lower extremity amputation (LEA) in Belgium, and to assess temporal trends in one-year survival rates from 2009 to 2018.

METHODS

Nationwide data on individuals who underwent minor and major LEA from 2009 to 2018 were collected. Kaplan-Meier survival curves were constructed. A Cox regression model with time-varying coefficients was used to estimate the likelihood of mortality after LEA in individuals with or without diabetes. Matched amputation-free individuals with or without diabetes were used for comparison. Time trends were analysed.

RESULTS

Amputations 41,304 were performed: 13,247 major and 28,057 minor. Five-year mortality rates in individuals with diabetes were 52% and 69% after minor and major LEA, respectively (individuals without diabetes: 45% and 63%, respectively). In the first six postoperative months, no differences in mortality rates were found between individuals with or without diabetes. Later, hazard ratios (HRs) for mortality in individuals with diabetes (compared with no diabetes) after minor LEA ranged from 1.38 to 1.52, and after major LEA from 1.35 to 1.46 (all p ≤ 0.005). Among individuals without LEA, HRs for mortality in diabetes (versus no diabetes) were systematically higher compared to the HRs for mortality in diabetes (versus no diabetes) after minor and major LEA. One-year survival rates did not change for individuals with diabetes.

CONCLUSIONS

In the first six postoperative months, mortality rates after LEA were not different between individuals with or without diabetes; later, diabetes was significantly associated with increased mortality. However, as HRs for mortality were higher in amputation-free individuals, diabetes impacts mortality less in the minor and major amputation groups relative to the comparison group of individuals without LEA.

Diabetic Foot Ulcer Management and Treatment: An Overview of Published Patents

BACKGROUND

One of the most challenging effects of diabetes is diabetic foot ulceration (DFU). DFU may occur in up to one-third of individuals with diabetes mellitus (D.M.) at some point in their lives. The major cause of morbidity in D.M. patients is DFU. The length of treatment is difficult, and DFU recurrence is common.

OBJECTIVE

The most crucial element for the treatment and prevention of DFUs require a multidisciplinary approach. Patients who are at risk should be identified, depending on the type of risk, prophylactic actions etc. It is imperative to identify at-risk patients and take preventative measures accordingly.

METHOD

The at-risk diabetes-related foot ulcer was identified based on the risk category classification, while the foot ulcers were evaluated using Wagner's classification system.

RESULTS

Literature reported that patients with lower limb vascular insufficiency, loss of vibratory sensation, or protective sensation loss have an increased risk of developing foot ulcers. Proper categorization and therapeutic measures will be implemented after the DFU has been formed. The appropriate assessment and management of general health status should include glycemic control, the diagnosis and treatment of vascular disease, standard care for wounds, diagnosis, and infection treatments.

CONCLUSION

The review reflects the updated awareness of the treatment and management of DFU based on the current and past literature and patent analysis.

Impact of multidisciplinary care of diabetic foot infections for inpatients at Campbelltown Hospital

BACKGROUND

Diabetic foot infection (DFI), including diabetic foot ulcer, is a serious complication of diabetes, particularly in the South Western Sydney (SWS) region where it is a leading cause of diabetes-related hospitalisations. Multidisciplinary team (MDT) involvement is effective at improving the health outcomes of DFI patients. This study investigated the impact of MDT (High Risk Foot Service, HRFS) on the length of stay and surgical outcomes of inpatients with DFI in a Sydney tertiary hospital.

METHOD

A retrospective audit of electronic medical records of inpatient admissions for DFI at Campbelltown Hospital between January 2019 - December 2021, was performed. The main outcome of the study was MDT involvement, defined as having two or more specialities involved in the patient's treatment. The other measured variables included length of stay (defined as the total duration from admission to discharge), and surgical outcomes including debridement, minor amputation, and major amputation.

RESULTS

Over the three years, 78 participants presented to the hospital for 89 unique DFI admissions. There were 24 admissions in 2019, 28 admissions in 2020, and 37 admissions in 2021, with MDT attendance showing a steady increase at 62.5%, 75.0% and 83.8% respectively. Patients with serious comorbidities such as chronic kidney disease were more likely to have MDT involvement (84.8% vs. 15.2%, P = 0.048). Imaging was more likely to be performed with MDT involvement (78.8% vs. 21.3%, p < 0.05). Comparing patients who received and did not receive MDT care, the mean HbA1c (%) (8.4 ± 2.0 vs. 8.2 ± 2.7, P = 0.701), median length of stay (LOS: 7.8, IQR 15.0 days vs. 4.8 IQR 7.9 days, P = 0.243) and rate of surgical outcomes (74.6% vs. 72.7%, P = 0.262) were similar. Patients who required major amputation had significantly longer LOS (24 days, IQR 21.5 vs. 5.2 days, IQR 13.0, P = 0.004) but similar HbA1c (P = 0.552) compared to those who had conservative intervention.

CONCLUSION

Adopting an MDT approach was associated with more thorough investigation of DFI, with similar rates of surgical outcomes. Further research on the impacts of MDT on length of stay and surgical outcomes of DFI patients in other SWS hospitals is needed.

Management of diabetic foot ulcers: a narrative review

Diabetic foot ulcers (DFUs) are among the most serious complications of diabetes and are a source of reduced quality of life and financial burden for the people involved. For effective DFU management, an evidence-based treatment strategy that considers the patient's clinical context and wound condition is required. This treatment strategy should include conventional practices (surgical debridement, antibiotics, vascular assessment, offloading, and amputation) coordinated by interdisciplinary DFU experts. In addition, several adjuvant therapies can be considered for nonhealing wounds. In this narrative review, we aim to highlight the current trends in DFU management and review the up-to-date guidelines.

A novel Canadian multidisciplinary acute care pathway for people hospitalised with a diabetic foot ulcer

This manuscript describes the implementation and initial evaluation of a novel Canadian acute care pathway for people with a diabetic foot ulcer (DFU). A multidisciplinary team developed and implemented an acute care pathway for patients with a DFU who presented to the emergency department (ED) and required hospitalisation at a tertiary care hospital in Canada. Processes of care, length of stay (LOS), and hospitalisation costs were considered through retrospective cohort study of all DFU hospitalizations from pathway launch in December 2018 to December 2020. There were 82 DFU-related hospital admissions through the ED of which 55 required invasive intervention: 28 (34.1%) minor amputations, 16 (19.5%) abscess drainage and debridement, 6 (7.3%) lower extremity revascularisations, 5 (6.1%) major amputations. Mean hospital LOS was 8.8 ± 4.9 days. Mean hospitalisation cost was $20 569 (±14 143): $25 901 (±15 965) when surgical intervention was required and $9279 (±7106) when it was not. LOS and hospitalisation costs compared favourably to historical data. An acute care DFU pathway can support the efficient evaluation and management of patients hospitalised with a DFU. A dedicated multidisciplinary DFU care team is a valuable resource for hospitals in Canada.

Hospital clinicians' perceptions and experiences of care pathways for chronic limb-threatening ischaemia: a qualitative study

BACKGROUND

Chronic limb-threatening ischaemia (CLTI) is a condition associated with significant risks of lower limb loss and mortality, which increase with delays in management. Guidance recommends urgent referral and assessment, but delays are evident at every stage of the CLTI patient pathway. This study uses qualitative methods to explore hospital clinicians' experiences and perceptions of the existing CLTI pathway.

METHODS

A qualitative interview study was conducted. Semi-structured interviews were undertaken with 13 clinicians involved in the assessment of patients referred to hospital with suspected CLTI, identified via purposive sampling from English vascular surgery units. Clinicians included podiatrists, vascular specialist nurses and doctors. Reflexive thematic analysis was performed on the data from a critical realist position.

RESULTS

The need for speed was the single overarching theme identified. Four linked underlying themes were also identified; 1. Vascular surgery as the poor relation (compared to cancer and other specialties), with a sub-theme of CLTI being a challenging diagnosis. 2. Some patients are more equal than others, with sub-themes of diabetes vs. non-diabetes, hub vs. spoke and frailty vs. non-frail. 3. Life in the National Health Service (NHS) is tough, with sub-themes of lack of resource and we're all under pressure. 4. Non-surgeons can help.

CONCLUSIONS

The underlying themes generated from the rich interview data describe barriers to timely referral, assessment and management of CLTI, as well as the utility of non-surgical roles such as podiatrists and vascular specialist nurses as a potential solution for delays. The overarching theme of the need for speed highlights the meaning given to adverse consequences of delays in management of CLTI by clinicians involved in its assessment. Future improvement projects aimed at the CLTI pathway should take these findings into account.

Issues and challenges in diabetic neuropathy management: A narrative review

Diabetic neuropathy (DN) is a devastating disorder with an increasing prevalence globally. This epidemic can pose a critical burden on individuals and com-munities, subsequently affecting the productivity and economic output of a country. With more people living a sedentary lifestyle, the incidence of DN is escalating worldwide. Many researchers have relentlessly worked on ways to combat this devastating disease. Their efforts have given rise to a number of commercially available therapies that can alleviate the symptoms of DN. Unfortunately, most of these therapies are only partially effective. Worse still, some are associated with unfavorable side effects. This narrative review aims to highlight current issues and challenges in the management of DN, especially from the perspective of molecular mechanisms that lead to its progression, with the hope of providing future direction in the management of DN. To improve the approaches to diabetic management, the suggested resolutions in the literature are also discussed in this review. This review will provide an in-depth understanding of the causative mechanisms of DN, apart from the insights to improve the quality and strategic approaches to DN management.

Diabetic foot ulcers: weekly versus second-weekly conservative sharp wound debridement

Diabetic foot ulcers (DFU) are a serious and costly long-term complication of diabetes, and are one of the most prevalent hard-to-heal (chronic) wound types. Conservative sharp wound debridement (CSWD) is a mainstay of care. It is performed regularly until healing is achieved (when there is adequate blood flow for healing) to support endogenous healing and improve the efficacy of advanced healing therapies. CSWD is supported by evidence-based treatment guidelines, despite a lack of prospective studies. The first prospective randomised study to compare different frequencies of CSWD-the Diabetes Debridement Study (DDS)-showed no difference in healing outcomes at 12 weeks between those ulcers debrided weekly and those debrided every second week. A DFU may require more or less frequent debridement according to individual wound characteristics; however, the new data from DDS can inform clinical decisions and service provision. The implications of weekly versus second-weekly debridement are discussed.

Diabetic foot in primary and tertiary (DEFINITE) Care: A health services innovation in coordination of diabetic foot ulcer (DFU) Care within a healthcare cluster - 18-month results from an observational population health cohort study

Diabetic Foot in Primary and Tertiary (DEFINITE) Care is an inter-institutional and multi-disciplinary team (MDT) health systems innovation programme at a healthcare cluster in Singapore. We aim to achieve coordinated MDT care across primary and tertiary care for patients with diabetic foot ulcers (DFU), within our public healthcare cluster - an integrated network of seven primary care polyclinics and two acute care tertiary hospitals (1700-bed and 800-bed) with a total catchment population of 2.2 million residents. Results from prospective DEFINITE Care is referenced against a retrospective 2013-2017 cohort, which was previously published. Cardiovascular profile of the study population is compared against the same population's profile in the preceding 12 months. Between June 2020 and December 2021, there were 3475 unique patients with DFU with mean age at 65.9 years, 61.2% male, mean baseline HbA1c at 8.3% with mean diabetes duration at 13.3 years, mean diabetes complication severity index (DCSI) at 5.6 and mean Charlson Comorbidity Index (CCI) at 6.8. In the 12-months preceding enrolment to DEFINITE Care, 35.5% had surgical foot debridement, 21.2% had minor lower extremity amputation (LEA), 7.5% had major LEA whilst 16.8% had revascularisation procedures. At 18-months after the implementation of DEFINITE Care programme, the absolute minor and major amputation rates were 8.7% (n = 302) and 5.1% (n = 176), respectively, equating to a minor and major LEA per 100000 population at 13.7 and 8.0, respectively. This represents an 80% reduction in minor amputation rates (P < .001) and a 35% reduction in major amputation rates (P = .005) when referenced against a retrospective 2013-2017 cohort, which had minor and major LEA per 100000 population at 68.9 and 12.4, respectively. As compared to the preceding 12 months, there was also a significant improvement in cardiovascular profile (glycemic and lipid control) within the DEFINITE population, with improved mean HbAc1 (7.9% from 8.4%, P < .001), low-density lipoprotein (LDL) levels (2.1 mmol/L from 2.2, P < .001), total cholesterol (3.9 mmol/L from 4.1, P < .001) and triglycerides levels (1.6 mmol/L from 1.8, P = .002). Multivariate analysis revealed a history of minor amputation in the preceding 12 months to be an independent predictor for major and minor amputation within the study period of 18 months (Hazard Ratio 3.4 and 1.8, respectively, P < .001). In conclusion, within DEFINITE care, 18-month data showed a significant reduction of minor and major LEA rates, with improved medical optimisation and cardiovascular profile within the study population.

Interprofessional communication in the hospital setting : a systematic review of the qualitative literature

Communication plays a key role in the provision of safe patient care, and miscommunication in healthcare can lead to avoidable patient harm or mortality. Interprofessional communication (IPCom) can be challenging due to differences in training, education and roles between healthcare professions. The aim of this systematic review was to synthesize the qualitative evidence regarding healthcare providers' perceptions of interprofessional communication in the hospital setting. Four databases (PubMed, CINAHL, Web of Science, and Embase) were searched for studies that met the inclusion criteria. Eighteen studies were identified as suitable for inclusion in the review and were examined using thematic synthesis. Thematic synthesis led to the development of five descriptive themes: 1) 'Hierarchy", 2) "Interprofessional Ethos," 3) "Healthcare Environment," 4) "Personal Factors" and 5) "Methods of Communication," and two overarching analytical themes: "Barriers to Communication" and "Facilitators to Communication." Personal factors, such as strong interprofessional relationships, were found to be important facilitators to IPCom, while organizational factors, such as challenging and hierarchical working environments, were found to pose barriers to IPCom.

A clinicopathological study on management of diabetic foot ulcer in tertiary care centre

INTRODUCTION

Diabetes is a disease in which the body's ability to produce or respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in the blood. India being the Diabetes Capital of the World has a Prevalence of 65.1 million suffering from DM of the Entire Indian Population being 1.33 billion of Worlds 6 billion people. This states that almost half of the Indian Population will sometime in their life be detected with Diabetes Almost 15-20 % of the population suffering from Diabetes are seen to have Diabetic Foot Ulcer at least once in their lifetime. It is also been noted that 10-15 % of patients suffering from Diabetic Foot Ulcer require Expert Management or Multi Disciplinary Approach. Diabetic foot ulcers have many pathogenic mechanisms, These risk factors are as follows: gender (male), duration of diabetes longer than 10 years, advanced age of patients, high Body Mass Index and other co-morbidities such as retinopathy, diabetic peripheral neuropathy, peripheral vascular disease, high glycated haemoglobin level (HbA1C), foot deformity, high plantar pressure, infections and inappropriate foot selfcare habits. Rough estimates are at about 1,00,000 lower limbs are amputated in India every year, of which at least seventy-five percent are neuropathic feet with secondary infections and are potentially preventable.

AIMS AND OBJECTIVES

Diabetes-Related Lower Extremity Amputations in Romania: Patterns and Changes between 2015 and 2019

Lower extremity amputations (LEAs) are a feared complication of diabetes mellitus (DM). Here we evaluated the recent trends in DM-related LEAs in Romania. We collected data from a national database regarding minor and major LEAs performed between 2015 and 2019 in patients with DM admitted to a public hospital. Absolute numbers of LEAs were presented by year, diabetes type, sex and age; incidence rates of LEAs in the general population were also calculated. Over the study period, 40,499 LEAs were recorded nationwide (83.16% in persons with type 2 DM [T2DM]); on average, the number of LEAs increased by 5.7%/year. This trend was driven by an increased number of LEAs in patients with T2DM; in patients with type 1 DM (T1DM), LEAs decreased over the study period. In patients with T2DM, the increase in minor LEAs was more pronounced than that in major LEAs. The overall number of LEAs showed an increasing trend with age (r = 0.72), which was most pronounced in patients aged ≥70 years. Men had a higher frequency of LEAs than women, regardless of DM type. These data support renewed efforts to prevent and decrease the burden of amputations among patients with DM.

Diabetic foot ulcers: A devastating complication of diabetes mellitus continues non-stop in spite of new medical treatment modalities

Diabetic foot ulcer is a devastating complication of diabetes mellitus and significant cause of mortality and morbidity all over the world and can be complex and costly. The development of foot ulcer in a diabetic patient has been estimated to be 19%-34% through their lifetime. The pathophysiology of diabetic foot ulcer consist of neuropathy, trauma and, in many patients, additional peripheral arterial disease. In particular, diabetic neuropathy leads to foot deformity, callus formation, and insensitivity to trauma or pressure. The standard algorithms in diabetic foot ulcer management include assessing the ulcer grade classification, surgical debridement, dressing to facilitate wound healing, off-loading, vascular assessment (status and presence of a chance for interventional vascular correction), and infection and glycemic control. Although especially surgical procedures are sometimes inevitable, they are poor predictive factors for the prognosis of diabetic foot ulcer. Different novel treatment modalities such as nonsurgical debridement agents, oxygen therapies, and negative pressure wound therapy, topical drugs, cellular bioproducts, human growth factors, energy-based therapies, and systematic therapies have been available for patients with diabetic foot ulcer. However, it is uncertain whether they are effective in terms of promoting wound healing related with a limited number of randomized controlled trials. This review aims at evaluating diabetic foot ulcer with regard to all aspects. We will also focus on conventional and novel adjunctive therapy in diabetic foot management.

People Living with Inflammatory Bowel Disease Want Multidisciplinary Healthcare: A Qualitative Content Analysis

This study reports on the preferences of people with inflammatory bowel disease (IBD) for their healthcare. Overall, 477 people with IBD responded to an open-ended survey question within a larger study. We qualitatively content-analysed these responses with open coding using NVivo. Respondents expressed a desire for (1) better communication, (2) multidisciplinary care, (3) better treatment, services and specialist care, (4) whole person care, (5) health promotion, (6) proactive healthcare, (7) fewer administrative issues and (8) improved hospital experience. Patients with IBD want patient-centred, multidisciplinary care. Healthcare professionals should facilitate patients' access to proactive care.

The Interdisciplinary Approach: Preventive and Therapeutic Strategies for Diabetic Foot Ulcers

The appropriate treatment of the common diabetic foot ulcers (DFUs) in diabetic patients demands enormous human, organizational and financial resources that are finite. Interdisciplinary teams of medical and surgical specialists, as well as allied health professionals, can help to reduce the consumption of these resources, optimize treatment, and prevent DFUs. They consist primarily of vascular surgeons, endocrinologists, and orthopedic foot and ankle surgeons and are closely supported when required by infectious diseases specialists, plastic surgeons, wound care specialist nurses, podiatrists, and orthotists. A timely interdisciplinary team review in each clinic session decreases the number of hospital visits for the oftentimes-handicapped diabetic patients significantly. The interdisciplinary team clinic setup has also been shown to reduce the risk of amputations, length of hospital staz and mortality rates.

Prevention and Management Strategies for Diabetic Neuropathy

Diabetic neuropathy (DN) is a common complication of diabetes that is becoming an increasing concern as the prevalence of diabetes rapidly rises. There are several types of DN, but the most prevalent and studied type is distal symmetrical polyneuropathy, which is the focus of this review and is simply referred to as DN. It can lead to a wide range of sensorimotor and psychosocial symptoms and is a major risk factor for diabetic foot ulceration and Charcot neuropathic osteoarthropathy, which are associated with high rates of lower limb amputation and mortality. The prevention and management of DN are thus critical, and clinical guidelines recommend several strategies for these based on the best available evidence. This article aims to provide a narrative review of DN prevention and management strategies by discussing these guidelines and the evidence that supports them. First, the epidemiology and diverse clinical manifestations of DN are summarized. Then, prevention strategies such as glycemic control, lifestyle modifications and footcare are discussed, as well as the importance of early diagnosis. Finally, neuropathic pain management strategies and promising novel therapies under investigation such as neuromodulation devices and nutraceuticals are reviewed.

Multidisciplinary extremity preservation program improves quality of life for patients with advanced limb threat

INTRODUCTION

The need for multidisciplinary care of patients with advanced limb threat is well established. We examined patient reported outcomes and health-related quality of life (HR-QoL) for those who completed a multidisciplinary extremity preservation program (EPP) at our institution.

METHODS

Patients with advanced limb threat, who had previously failed standard management at a tertiary-care center, were referred to EPP for evaluation by a multidisciplinary panel of vascular, plastic, orthopedic and podiatric surgeons, along with infectious disease, prosthetics, orthotics, imaging, palliative care, social work and wound nursing specialists. HR-QoL was quantified before and after EPP participation with the RAND-36 questionnaire. The validated RAND-36 assesses physical function, role limitations caused by physical and emotional health problems, social functioning, emotional well-being, energy, pain and general health perceptions.

RESULTS

From 2018 to 2020, 185 patients were referred to EPP. After review by the multidisciplinary panel, 120 were accepted into the program, 63 of whom completed their course of care; 9 were one-time consultations. The median number of EPP in-person care visits was 23 (13-54) per participant; 87.3% of patients received one or more surgical procedure, including operative debridement (73%), revascularization (44%), soft tissue reconstruction or transplantation (46%), as well as hyperbaric oxygen therapy (11%) during their course of treatment. 85.7% of patients achieved complete wound healing, 41.5% occurring within 6 months. Ultimately, 14.3% required a major amputation. Graduates noted improvement in all categories of the HR-QoL upon completion, including those undergoing major amputation. On adjusted multivariate regression analysis, patients with immunocompromised status were more likely to show greater improvement in their social function (OR: 10.1; P<0.044) and emotional role limitation (OR:8.1; P=0.042), while patients with larger wound volume at presentation were more likely to have greater improvement in their general health (OR: 1.1; P<0.049). Conversely, patients with a smoking history had less improvement in energy level (OR:0.4; P=0.044) and patients with dialysis-dependence had less improvement in social function (OR:0.2; P=0.034).

CONCLUSION

Coordinated, multidisciplinary extremity preservation program improves HR-QoL of patients with complex limb threat, including those who are immunocompromised with impaired social function and emotional role limitations. Further study is warranted to better characterize the generalizability of this approach, including considerations of cost-effectiveness, wound recidivism, and limiting the number of in-person visits required to achieve complete healing.

Temporal trends in major, minor and recurrent lower extremity amputations in people with and without diabetes in Belgium from 2009 to 2018

AIMS

This study assessed temporal trends in the incidence of lower extremity amputations (LEA) in Belgium from 2009 to 2018, and subsequent secondary amputation rates.

METHODS

Nationwide data on LEA were collected. Sex- and age-adjusted annual incidence rates were calculated. Time trends were analysed in negative binomial models. The incidence of secondary interventions, defined as either any ipsilateral reamputation or any contralateral amputation, was studied with death as competing risk.

RESULTS

41 304 amputations were performed (13 247 major, 28 057 minor). In individuals with diabetes, the amputation rate (first amputation per patient per year) decreased from 143.6/100.000 person-years to 109.7 (IRR 0.97 per year, 95 %CI 0.96-0.98, p < 0.001). The incidence of major LEAs decreased from 56.2 to 30.7 (IRR 0.93, 95 %CI 0.91-0.94, p < 0.001); the incidence of minor amputations showed a non-significant declining trend in women (54.3 to 45.0/100 000 person years, IRR 0.97 per year, 95 %CI 0.96-0.99), while this remained stable in men with diabetes (149.2 to 135.3/100 000 person years, IRR 1.00 per year, 95 %CI 0.98-1.01). In individuals without diabetes, the incidence of major amputation didn't change significantly, whereas minor amputation incidence increased (8.0 to 10.6, IRR 1.04, 95 %CI 1.03-1.05, p < 0.001). In individuals with diabetes, one-year secondary intervention rates were high (31.3% after minor, 18.4% after major LEA); the incidence of secondary amputations didn't change.

CONCLUSIONS

A significant decline in the incidence rate of major LEA was observed in people with diabetes. This decline was not accompanied by a significant rise in minor LEA. The incidence of secondary interventions remained stable.

Clinical and economic outcomes of a multidisciplinary team approach in a lower extremity amputation prevention programme for diabetic foot ulcer care in an Asian population: A case-control study

Present guidelines recommend a multidisciplinary team (MDT) approach to diabetic foot ulcer (DFU) care, but relevant data from Asia are lacking. We aim to evaluate the clinical and economic outcomes of an MDT approach in a lower extremity amputation prevention programme (LEAPP) for DFU care in an Asian population. We performed a case-control study of 84 patients with DFU between January 2017 and October 2017 (retrospective control) vs 117 patients with DFU between December 2017 and July 2018 (prospective LEAPP cohort). Comparing the clinical outcomes between the retrospective cohort and the LEAPP cohort, there was a significant decrease in mean time from referral to index clinic visit (38.6 vs 9.5 days, P < .001), increase in outpatient podiatry follow-up (33% vs 76%, P < .001), decrease in 1-year minor amputation rate (14% vs 3%, P = .007), and decrease in 1-year major amputation rate (9% vs 3%, P = .05). Simulation of cost avoidance demonstrated an annualised cost avoidance of USD $1.86m (SGD $2.5m) for patients within the LEAPP cohort. In conclusion, similar to the data from Western societies, an MDT approach in an Asian population, via a LEAPP for patients with DFU, demonstrated a significant reduction in minor and major amputation rates, with annualised cost avoidance of USD $1.86m.

Diabetes-related foot disease research in Aotearoa New Zealand: a bibliometric analysis (1970-2020)

Background

The aim of this bibliometric study was to examine trends in the quality and quantity of published diabetes-related foot disease (DRFD) research in Aotearoa/New Zealand (NZ) over the past five decades.

Method

In July 2021, the Scopus® database was searched for DRFD-related publications (1970–2020) using predetermined search and inclusion criteria. Bibliometric data were extracted from Scopus® and Journal Citation Reports. Retrieved bibliometric indicators were analysed in Biblioshiny, an R Statistical Software interface and reported using descriptive statistics.

Results

Forty-seven DRFD-related articles were identified. The annual number of publications showed a significant upward trend increasing from one in 1988 to a peak of six in 2018 (P < 0.001). The majority of identified articles (n = 31, 66%) were published in the last decade (2011–2020). Basic/clinical research accounted for 87% (n = 41) of publications and 14 (30%) investigated the screening and/or prevention of DRFD. The average citation per article was 20.23 (range: 0–209) and the median impact factor was 4.31 (range, 1.82–79.32). Over a third of articles (36%) had an international authorship network. Funding was reported in 15 (32%) articles; 12 (26%) were supported by public national grants vs. three (6%) reporting industry-sponsorship.

Conclusion

DRFD articles authored by NZ researchers have increased over the past five decades. Despite NZ researchers having increased their global impact through collaborative networks, most of the research was classified as low-level evidence, with limited focus on Indigenous Māori and limited financial support and funding. Increased funding for interventional research is required to enable a higher level of evidence-based and practice-changing research to occur. With rates of diabetes-related amputations higher in Māori future research must focus on reducing inequalities in diabetes-related outcomes for Māori by specifically targeting the prevention and screening of DRFD in primary care settings in NZ.

Geographic and Ethnic Inequalities in Diabetes-Related Amputations

Individuals with diabetes mellitus are at increasing risk for major lower-extremity amputations (LEAs). Poor quality of life and remarkable disabilities are associated with LEAs, determining a high economic burden for the healthcare systems. Reducing LEAs is therefore a primary marker of quality of care of the diabetic foot. At global level, between-countries comparisons of LEAs rates are basically hampered by differences in criteria used for data collection and analysis among studies. Significant variability in amputation rates exists between geographic areas, and also within specific regions of a country. Overall 5-year mortality rate after major amputations is reported to vary substantially across countries, from 50 to 80%. The odds of LEAs are substantially higher for Black, Native American and Hispanic ethnicities compared with White groups, with similar figures observed in the economically disadvantaged areas compared to more developed ones. Such discrepancies may reflect differences in diabetes prevalence as well as in financial resources, health-care system organization and management strategies of patients with diabetic foot ulcers. Looking at the experience of countries with lower rates of hospitalization and LEAs worldwide, a number of initiatives should be introduced to overcome these barriers. These include education and prevention programs for the early detection of diabetic foot at primary care levels, and the multidisciplinary team approach with established expertise in the treatment of the more advanced stage of disease. Such a coordinated system of support for both patients and physicians is highly required to reduce inequalities in the odd of diabetes-related amputations worldwide.

Hyperbaric oxygen therapy: when pressure is good for diabetic foot ulcers

The diabetic foot ulcer (DFU) as a common complication of diabetes. Even with adequate treatment, up to 35% of these ulcers do not heal. This is due to the effect of aging, repeated ischemia-reperfusion (IR) injury, bacterial colonisation of the wound and chronic hypoxia. All wound-healing processes are highly dependent on oxygen, so hyperbaric oxygen therapy (HBOT) can be employed to improve wound healing and correct the four pathophysiological factors for chronic wounds. It is, in fact, internationally recognised as a treatment option for non-healing DFUs. Several trials and systematic reviews have been performed on its efficacy, which show a positive trend towards increased wound healing and reduced amputation risk. Some controversy exists due to contradictory results in these studies, which may be due to grouping patients with and without peripheral arterial occlusive disease (PAOD) together. Side effects are usually mild and transient, and the treatment is considered safe.

Management of diabetic foot ulcers and the challenging points: An endocrine view

Diabetic foot ulcers (DFU) are one of the most challenging complications of diabetes. Up to one-third of patients with diabetes mellitus (DM) may suffer from DFUs during their life. DFU is one of the leading causes of morbidity in patients with DM. The treatment period is challenging, and the recurrence rate of DFUs is high. Hence, establishing prevention strategies is the most important point to be emphasized. A multidisciplinary approach is necessary in the prevention and treatment of DFUs. Patients at risk should be identified, and prevention measures should be taken based on the risk category. Once a DFU is formed, the appropriate classification and evidence-based treatment interventions should be executed. Glycemic control, diagnosis and treatment of vascular disease, local wound care, diagnosis, and treatment of infection should be addressed along with the proper evaluation and management of general health status.

What is the Lived Experience of the ‘Three Great Pathologies’ of Diabetic Foot Disease? An Interpretative Phenomenological Analysis of the Independent Thinking of Podiatrists in Diabetes Secondary Care

Researching the podiatrists’ lived experience of The Three Great Pathologies may help improve the quality of patient care. The aim of this research using an Interpretative Phenomenological Analysis approach is to report on insights relating to the Three Great Pathologies of diabetic foot disease – infection, ischaemia and amputation. To do this, data was collected from six New Zealand diabetes care Podiatrists. Three superordinate themes resulted with subordinate themes. They are compromised health status, podiatric challenges and best outcomes. The findings are firstly, patient education remains a priority; secondly, there is an unmet need for postgraduate podiatry education; and thirdly, early intervention is a key measure for reducing the influence of the Three Great Pathologies. This study demonstrates that focussing on a group of six specialist podiatrists contributes to new priorities of care for dealing with the Three Great Pathologies of diabetic foot disease.

Will Multidisciplinary Collaboration Reduce the Disability Rate of Diabetic Foot (2009-2019)?-A Study Based on the Perspective of Organizational Reform

Objectives: Discuss the experience and practice of multidisciplinary cooperation of diabetic foot in China and analyze its impact on the quality of care.

Methods: This study observed the medical procedure by interviewing 12 key personnel in-depth. We extracted data from medical records and assessed the effect of MDT in three dimensions: quality, efficiency, and cost, to eventually achieve a final conclusion.

Results: The studied reform includes the following three aspects: the adjustment of hospital buildings layout and disciplines, one-stop outpatient, and one-stop inpatient service. After the multidisciplinary collaboration, the rate of above-knee amputation is reduced by 3.63%, the disability score per 100 diabetic foot patients decreases by 6.12, the average length of stay decreases significantly, and the cost of hospitalization shows an increasing trend.

Conclusions: Multidisciplinary collaboration is performed based on spatial layout adjustment and clinical pathway optimization, which provide more comprehensive and integrated care than a general medical team or a single specialist, thereby reducing the rate of disability, shortening the length of hospitalization. Besides, the new measurable indicator called disability score per 100 diabetic foot patients has been verified to evaluate the living ability of patients after surgery. This paper provides a reference for organizational reform of multidisciplinary diseases to support treatment and management of other multiorgan diseases.

ECONOMIC VALUE OF PODIATRY SERVICE IN LIMB SALVAGE ALLIANCE

INTRODUCTION

Over the last decade, multidisciplinary "toe and flow" programs have gained great popularity with proven benefits in limb salvage. Many vascular surgeons have incorporated podiatrists into their practices. The viability of this practice model requires close partnership, hospital support, and financial sustainability. We intend to examine the economic values of podiatrists in a busy safety-net hospital in the Southwest United States.

METHODS

An administrative database that captured monthly OR cases, clinic encounters, in-patient volume, and total work relative value units (wRVU) in an established limb salvage program in a tertiary referral center were examined. The practice has a diverse patient population with >30% of minority patients. During a period of three years, there was a significant change in the number of podiatrists (n=1 to 4) within the program where the clinical full-time employees for vascular surgeons remained relatively stable.

RESULTS

The limb salvage program experienced >100% of growth in total OR volumes, clinic encounters, and total wRVUs over a period of four years. A total of 35,591 patients were evaluated in a multidisciplinary limb salvage clinic and 5535 procedures were performed. The initial growth of clinic volume and operative volume (P<0.01) were attributed by the addition of vascular surgeons in year one. However, recruitment of podiatrists to the program significantly increased clinic and OR volume by an additional 60% and >40% respectively (P<0.01) in the last three years. With equal number of surgeons, podiatry contributed 40% of total wRVUs generated by the entire program in 2019. Despite that most of the foot and ankle procedures that were regularly performed by vascular surgeons were shifted to the podiatrists, vascular surgeons continued to experience an incremental increase in operative volume and >10% of increase in wRVUs.

CONCLUSION

This study shows that the value of close collaboration between podiatry and vascular in a limb salvage program extends beyond a patient's clinical outcome. A financial advantage of including podiatrist in a vascular surgery practice is clearly demonstrated.

Nationwide prevalence and clinical characteristics of inpatient diabetic foot complications: A Peruvian multicenter study

OBJECTIVE

To evaluate the burden of diabetic foot complications amongst inpatients in Peru.

MATERIALS AND METHODS

Cross-sectional multicenter study, performed in public hospitals, in one-day enrollment between October and December 2018.

RESULTS

We included 8346 patients from 39 national hospitals. Diabetic foot (DF) inpatient point prevalence was 2.8% (CI 95% 2.4-3.1), and DF point prevalence among Diabetes Mellitus (DM) inpatients was 18.9% (CI 95% 16.7-21.1). DF prevalence was higher in jungle and coastal hospitals than highlands ones, and there was no difference according to its care complexity level. Of the 234 patients with DF, 73% were males, age average was 62 ± 12 years, with DM mean time duration of 15 ± 9.9 years. Regarding to DF etiology, 91% and 68% had some degree of peripheral neuropathy and peripheral artery disease, respectively. According to the Infectious Diseases Society of America criteria, 61% presented moderate to severe infections, and 40% had bone involvement. Debridement within 48 h was performed in 36% of sepsis cases.

CONCLUSION

Peru has a substantial burden of DF disease, with a greater share of that burden falling on less equipped hospitals in the country's jungle and coastal regions. Interdisciplinary teams and pathways may improve the time of surgical debridement in the highest risk patients.

Demographics and outcomes of inpatients with diabetic foot ulcers treated conservatively and surgically in a metropolitan hospital network

AIMS

To describe the demographics of patients with diabetic foot ulcers (DFU) and their impact on inpatient management. Secondary outcomes identified relationships of treatment modality with mortality, length of hospital admission, readmissions and post-admission care.

METHODS

Retrospective cohort study including patients with DFU admitted to a hospital network in Melbourne, Australia from 2016 to 2018. Medical records were manually reviewed for acute admission with DFU as a major presenting diagnosis; incidental ulcers and traumatic amputations were excluded. Amputations distal and proximal to the ankle were labelled 'minor' and 'major' respectively. Patients were followed until October 31, 2019.

RESULTS

Of 338 patients, 21 and 148 had major and minor amputations, and 169 were managed conservatively. 94% had ≥1 microvascular and/or macrovascular complication. Conservative management (7 days) was associated with a shorter length of stay (major 18, minor 10 days, p < 0.001). Readmission rates were not significantly different. Mortality was greatest (38%) and survival time shortest (999 days) after major amputation than after either other treatment. Other factors associated with mortality were age and a history of coronary artery disease.

CONCLUSIONS

Early identification and multi-disciplinary management of DFU is essential to reduce the significant morbidity and mortality associated with amputation in these complex patients.

The tip of the iceberg: an overview of diabetic foot disease

Diabetic foot disease is the leading cause of lower-extremity amputation globally and imposes a significant burden for healthcare services and patients alike. The main pathology is ulceration, due to neuropathy or peripheral arterial disease. The most frequent sign is ulceration on the foot. Ulceration needs to be referred to the multidisciplinary diabetic foot team promptly for a comprehensive management plan to be developed. Delay in referral is associated with poor outcomes. Management of diabetic foot ulceration is multifaceted, including offloading, revascularisation, infection control, debridement, glycaemic control and wound care. Management plans need to be patient focused and developed collaboratively across primary and secondary care settings.

Interdisciplinary Care for Amputees Network: A Novel Approach to the Management of Amputee Patient Populations

Extremity amputation remains a common intervention for limb-threatening conditions. With advancement in surgical technique to address deleterious postoperative sequelae of limb removal, there is a salient need to develop and operationalize interdisciplinary care frameworks to provide more comprehensive care to an otherwise challenging patient population. Herein, we describe our interdisciplinary approach to the management of amputee patient populations at our institution, referred to as the Interdisciplinary Care for Amputees Network (ICAN). This novel framework focuses on 3 fundamental areas: combined preoperative patient evaluation, orthoplastic surgical intervention, and multi-specialty postoperative functional and psychosocial rehabilitation. Importantly, the successful implementation of a combined orthoplastic clinic requires establishing a working relationship among providers to leverage increased provider familiarity. This, coupled with sufficient clinic space, dedicated operating room time, and standardized patient workflow, serves to improve care and meet patient goals of pain minimization, return to desired functional status, and improvement in quality of life.

Diabetic foot ulcers: Epidemiology and the role of multidisciplinary care teams

Diabetic foot ulcers (DFUs) are a common but highly morbid complication of long-standing diabetes, carrying high rates of associated major amputation and mortality. As the global incidence of diabetes has increased, along with the lifespan of the diabetic patient, the worldwide burden of DFUs has grown steadily. Outcomes in diabetes and DFUs are known to depend strongly on social determinants of health, with worse outcomes noted in minority and socioeconomically disadvantaged populations. Effective treatment of DFUs is complex, requiring considerable expenditure of resources and significant cost to the health care system. Comprehensive care models with multidisciplinary teams have proven effective in the treatment of DFUs by decreasing barriers to care and increasing access to the multiple specialists required to provide timely and effective DFU procedural intervention, surveillance, and preventative care. Vascular surgeons are an integral part throughout the cycle of care for DFUs and should be involved early in the course of such patients to maximize their contributions to a multidisciplinary care model.

Conservative Management of Catastrophic Antiphospholipid Syndrome-Related Skin Necrosis: A Case Report

Catastrophic antiphospholipid syndrome is an extremely rare autoimmune disease with complex and diverse clinical manifestations. Cutaneous necrosis is one of its rare clinical features. However, interventions for this manifestation are not standardized and lack evidence, which increases treatment difficulty. Here, study authors report the successful care and follow-up of a 46-year-old female patient with nephrotic syndrome and catastrophic antiphospholipid syndrome complicated by full-thickness cutaneous necrosis of the dorsum of the right hand that lasted more than 4 months and 1 month prior to wound treatment, respectively. Study authors set up an interprofessional team, including a nephrologist, a vascular surgeon, and two specialist wound care nurses to provide holistic wound care and treat her complex systemic conditions. After 84 days of treatment, which involved removing necrotic tissue with autolytic wound debridement, reducing inflammation with hydrofiber dressings containing silver, and promoting re-epithelialization with hydrocolloid paste and systemic medications, the wound healed successfully. Authors followed up with the patient at 1, 4, 6, 11, and 19 months after healing. The quality of scar was monitored, and the function of her right hand recovered normally.

Quality of Diabetic Foot Ulcer Care: Evaluation of an Interdisciplinary Wound Care Clinic Using an Extended Donabedian Model Based on a Retrospective Cohort Study

OBJECTIVES

Diabetic foot ulcer (DFU), a serious complication of diabetes, is associated with increased morbidity and mortality and presents a substantial socioeconomic burden. However, DFU quality of care has been insufficiently studied. Therefore, the aim of this study was to evaluate the quality of DFU care at an interdisciplinary wound care clinic in Canada, based on an extended Donabedian model: structure, process and outcome quality indicators combined with patient characteristics.

METHODS

This was a retrospective cohort study of 140 adult patients with diabetes who were treated between 2012 and 2018 at a wound care clinic in a university-affiliated hospital in the Québec City area of Canada. Twenty-two internationally recognized quality-of-care indicators were identified from the literature. Data were collected from medical files, and the results were used to document the selected quality-of-care indicators.

RESULTS

The principal indicators regarding structure and process were met, and outcome indicators were influenced by study population characteristics, particularly peripheral artery disease and critical limb ischemia. Moreover, this study highlights that quality-of-care indicators are essential when evaluating DFU outcomes, as structure and process indicators can also affect wound healing outcomes.

CONCLUSIONS

This study suggests that DFU care at a Canadian wound care clinic, with an interdisciplinary approach, meets most quality-of-care indicators. The socioeconomic burden of DFUs for patients, health-care organizations and policymakers, and the paucity of quality and performance evaluations, call for more studies evaluating DFU care.

The utilisation of vascular limb salvage services in the assessment and management of chronic limb-threatening ischaemia and diabetic foot ulceration: A systematic review

Specialist vascular limb salvage services have gained prominence as a new model of care to help overcome barriers which exist in the management of patients with chronic limb-threatening ischaemia (CLTI) and/or diabetic foot ulceration (DFU). This systematic review aims to explore the nature of reported services, investigate their outcome in the management of CLTI/DFU, and assess the scope and quality of the evidence base to help make recommendations for future practice and research. A systematic search of MEDLINE, Embase, The Cochrane Library, Scopus and CINAHL, from 1st January 1995 to 18th January 2019, was performed. Specialist vascular limb salvage services were defined as those services conforming to the definition of "centres of excellence" within the 2019 Global Vascular Guidelines. A study protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42019123325). In total, 2260 articles were screened, with 12 articles (describing 11 services) included in a narrative synthesis. All services ran akin to the "toe-and-flow" model, with a number of services having additional core input from diabetology, microbiology, allied health professionals and/or internal/vascular medicine. Methodological weaknesses were identified within the design of the included articles and only one was deemed of high quality. The inception of services was associated with improved rates of major amputation; however, no significant changes in minor amputation or mortality rates were identified. Further research should adopt more a standardised study design and outcomes measures in order to improve the quality of evidence within the literature.

Knowledge of diabetic foot care management among medical students at King Abdulaziz University Hospital, Jeddah, Saudi Arabia

OBJECTIVES

To evaluate medical students' knowledge of diabetic foot care management and its related factors.

METHODS

This was a cross-sectional, descriptive study of 303 students studying at King Abdulaziz University Hospital, Jeddah, Saudi Arabia conducted from June to July 2019. Data were collected using a two-part questionnaire. The first one captured student information; the second assessed student knowledge. It consists of 68 true and false questions divided into 4 subscales (risk factors, foot examination, foot complications and footwear selection). The higher the total score is, the higher the students' knowledge.

RESULTS

The total average knowledge score was 55.5±5.5 out of 68. While the mean score was 14.11/16 for risk factors, 9.24/10 for foot examination, 24.21/32 for foot complications, and 7.88/10 for footwear selection subscales. Only 56.4% of students educated diabetic patients about diabetic foot risks;concurrently, only 63% performed foot examinations in diabetes patients. Students who educated diabetic patients, preformed foot exam, or attended extra elective clinical rotation in a diabetic foot team, had a significantly higher knowledge level. Conclusion: Students were found to have high level of knowledge regarding diabetic foot management. Students who educated patients about diabetic foot risk, performed foot examination on patients and students who took elective rotations in a diabetic foot care team had a higher knowledge level.

Organizational changes in diabetic foot care practices for patients at low and moderate risk after implementing a comprehensive foot care program in Alberta, Canada

BACKGROUND

Neuropathy and vasculopathy can lead to costly and debilitating complications in people with diabetes. The purpose of this study was to evaluate, at an organizational level, uptake of practices included in a diabetic foot care clinical pathway and associated resources. This research focused on patients at low and moderate risk in Alberta, Canada between 2014 to 2019.

METHODS

Serial surveys (2014, 2019) of practices related to screening and care of the feet of people with diabetes. Surveys were administered using a combination of targeted and snowball sampling in order to assess the impact of the clinical pathway first implemented in 2015. The pathway focused on screening, assessment and referral of patients from primary care. High-risk foot teams (HRFT) were established at six sites to provide increased access to specialty care. Comparative statistics were performed to assess differences in footcare practices between 2014 and 2019 using two-tailed Fisher's exact test or Chi-square test.

RESULTS

Respondents (n = 104, 2014 and n = 75, 2019) included personnel from primary health care, home care and long-term care, acute and emergency care, specialty clinics, diabetes-specific programs and private contractors. The proportion of primary care and home care/long-term care (HC/LTC) sites providing screening increased significantly (p < 0.05). A significant increase in the proportion of sites providing assessment for patients designated as moderate risk also increased from 35% (34 out of 96 sites) to 55% (36 out of 65 sites) (p < 0.05), particularly with respect to vascular assessment, and the proportion of sites reporting appropriate follow-up intervals according to the pathway recommendation was also improved.

CONCLUSION

Provision of a clinical pathway for diabetic foot care along with education and resources led to increased screening in primary care and HC/LTC settings in Alberta, Canada. HRFT provided primary healthcare providers with an important option for referral and also provided increased expertise for procedures such as vascular assessment for patients with moderate risk of ulceration. This comprehensive model has the potential to reduce progression of foot problems and overall health services utilization. Further analyses of outcomes such as incident lower limb amputation and long-term cost-effectiveness of pathway implementation are underway.

Clinical Characteristics, Treatment, and Prognosis of Diabetic Foot Disease in Macao and Beijing: A Retrospective Study

INTRODUCTION

There has been no epidemiological study of diabetes mellitus (DM) in Macao. Also, multidisciplinary treatment is yet to be popularized and complications of DM cannot be managed promptly in this region. Therefore, this study was performed to compare the clinical characteristics, treatment, and prognosis of diabetic foot disease between patients in Macao and Beijing.

METHODS

A total of 243 patients with diabetic foot disease were enrolled: 124 from a tertiary hospital in Beijing and 119 from a tertiary hospital in Macao. The clinical profiles were collected and analyzed.

RESULTS

The surgical treatment rate in the Beijing group (96.0%) was significantly higher than that in the Macao group (21.0%) (P < 0.05). The overall mortality rate was 14.8%, and cardiac failure was the most common cause (72.2%). Monthly household income and smoking were independent factors affecting the age of onset. Age of diabetes onset was a risk factor for the occurrence of diabetic foot disease; age, duration of diabetic foot disease, and length of smoking history were independent factors affecting the severity of diabetic foot disease. Renal dysfunction and activated partial thromboplastin time were independent factors affecting the survival time of patients with diabetic foot disease.

CONCLUSIONS

Smoking may be a risk factor for the occurrence and development of diabetic foot; it can significantly reduce the onset age and aggravate the severity of this disease. The onset age of diabetic foot was lower in high-income patients, and prevention should be encouraged in this population. Elderly age may be associated with a rapidly developing and severe diabetic foot. The clinical course was also associated with the severity of diabetic foot. Renal and coagulation function should be closely monitored during the treatment of diabetic foot.

Multidisciplinary Management of Diabetic Foot Ulcers in Primary Cares in Quebec: Can We Do Better?

A growing body of evidence supports the presence of integrated foot care based on multidisciplinary and interdisciplinary teams in the management and prevention of diabetic foot ulcer (DFU) worldwide. This model of care is however rare in the clinical setting in Quebec, Canada. Many best practice gaps are identified as well as probable causal hypothesis are listed in this commentary. We support our opinions with a pilot audit conducted as part of a continuous quality improvement process in managing patients with DFU in our area and on Canadian facts and data. Our pilot study (n = 27 hospitalized patients) included a typical DFU population with neuropathy, peripheral arterial disease and previous amputation. It highlights underachievement of best practice recommendations implementation such as multidisciplinary DFU management and offloading interventions in our establishment. Due the high morbidity and mortality associated with DFU patients, four died during the studied hospitalization episode. Several barriers were encountered in the pilot audit justifying that no robust conclusion can be raised. However, our observations are concerning. Even though data accessibility was limited, our observations are sadly coherent with what is found in the literature. Economic data of what this means for our health system is put forward in the overall discussion. We are preoccupied by the trends outlined by some facts and observations, and this commentary was written with this in mind. In the face of the diabetes crisis that is arising, a plea is made to reassess care pathway for this vulnerable population as we emphasize the importance of teamwork in managing DFU.
