Can the introduction of a 12-lead ECG help reduce mortality in those presenting with foot ulceration to multidisciplinary diabetic foot clinics? An observational evaluation of a real-world implementation pilot in England.

AIMS/HYPOTHESIS: The risk of dying within 2 years of presentation with diabetic foot ulceration is over six times the risk of amputation, with CVD the major contributor. Using an observational evaluation of a real-world implementation pilot, we aimed to assess whether for those presenting with diabetic foot ulceration in England, introducing a 12-lead ECG into routine care followed by appropriate clinical action was associated with reduced mortality. METHODS: Between July 2014 and December 2017, ten multidisciplinary diabetic foot services in England participated in a pilot project introducing 12-lead ECGs for new attendees with foot ulceration. Inception coincided with launch of the National Diabetes Footcare Audit (NDFA), whereby all diabetic footcare services in England were invited to enter data on new attendees with foot ulceration. Poisson regression models assessed the mortality RR at 2 and 5 years following first assessment of those receiving care in a participating pilot unit vs those receiving care in any other unit in England, adjusting for age, sex, ethnicity, deprivation, type and duration of diabetes, ulcer severity, and morbidity in the year prior to first assessment. RESULTS: Of the 3110 people recorded in the NDFA at a participating unit during the pilot, 33% (1015) were recorded as having received an ECG. A further 25,195 people recorded in the NDFA had attended another English footcare service. Unadjusted mortality in the pilot units was 16.3% (165) at 2 years and 37.4% (380) at 5 years for those who received an ECG, and 20.5% (430) and 45.2% (950), respectively, for those who did not receive an ECG. For people included in the NDFA at other units, unadjusted mortality was 20.1% (5075) and 42.6% (10,745), respectively. In the fully adjusted model, mortality was not significantly lower for those attending participating units at 2 (RR 0.93 [95% CI 0.85, 1.01]) or 5 years (RR 0.95 [95% CI 0.90, 1.01]). At participating units, mortality in those who received an ECG vs those who did not was lower at 5 years (RR 0.86 [95% CI 0.76, 0.97]), but not at 2 years (RR 0.87 [95% CI 0.72, 1.04]). Comparing just those that received an ECG with attendees at all other centres in England, mortality was lower at 5 years (RR 0.87 [95% CI 0.78, 0.96]), but not at 2 years (RR 0.86 [95% CI 0.74, 1.01]). CONCLUSIONS/INTERPRETATION: The evaluation confirms the high mortality seen in those presenting with diabetic foot ulceration. Overall mortality at the participating units was not significantly reduced at 2 or 5 years, with confidence intervals just crossing parity. Implementation of the 12-lead ECG into the routine care pathway proved challenging for clinical teams-overall a third of attendees had one, although some units delivered the intervention to over 60% of attendees-and the evaluation was therefore underpowered. Nonetheless, the signals of potential mortality benefit among those who had an ECG suggest that units in a position to operationalise implementation may wish to consider this.

A RAND/UCLA-Modified VAS Study on Telemedicine, Telehealth, and Virtual Care in Daily Clinical Practice of Vascular Medicine.

Background: Telemedicine is increasingly used in several fields of healthcare, including vascular medicine. This study aimed to investigate the views of experts and propose clinical practice recommendations on the possible applications of telemedicine in vascular medicine. Methods: A clinical guidance group proposed a set of 67 clinical practice recommendations based on the synthesis of current evidence and expert opinion. The Telemedicine Vascular Medicine Working Group included 32 experts from Europe evaluating the appropriateness of each clinical practice recommendation based on published RAND/UCLA methodology in two rounds. Results: In the first round, 60.9% of clinical practice recommendations were rated as appropriate, 35.9% as uncertain, and 3.1% as inappropriate. The strongest agreement (a median value of 10) was reached on statements regarding the usefulness of telemedicine during the 2019 coronavirus disease (COVID-19) pandemic, its usefulness for geographical areas that are difficult to access, and the superiority of video calls compared to phone calls only. The lowest degree of agreement (a median value of 2) was reported on statements regarding the utility of telemedicine being limited to the COVID-19 pandemic and regarding the applicability of teleconsultation in the diagnosis and management of abdominal aortic aneurysm. In the second round, 11 statements were re-evaluated to reduce variability. Conclusions: This study highlights the levels of agreement and the points that raise concern on the use of telemedicine in vascular medicine. It emphasizes the need for further clarification on various issues, including infrastructure, logistics, and legislation.

Validation of the Fast-Track Model: A Simple Tool to Assess the Severity of Diabetic Foot Ulcers.

This study aimed to validate the association between the grades of severity of diabetic foot ulcers (DFUs) identified by the fast-tack model and specific outcomes. Three hundred and sixty-seven patients with new DFUs who were referred to a tertiary level diabetic foot service serving Rome, Italy, were included. The fast-track model identifies three levels of DFUs' severity: uncomplicated DFUs, including superficial wounds, not-infected wounds, and not-ischemic wounds; complicated DFUs, including ischemic wounds, infected wounds, and deep ulcers involving the muscles, tendons, or bones, and any kind of ulcers in patients on dialysis and/or with heart failure; and severely complicated DFUs, including abscesses, wet gangrene, necrotizing fasciitis, fever, or clinical signs of sepsis. Healing, minor and major amputation, hospitalization, and survival after 24 weeks of follow-up were considered. Among the included patients, 35 (9.6%) had uncomplicated DFUs, 210 (57.2%) had complicated DFUs, and 122 (33.2%) had severely complicated DFUs. The outcomes for patients with uncomplicated, complicated, and severely complicated DFUs were as follows, respectively: healing, 97.1%, 86.2%, and 69.8%; minor amputation, 2.9%, 20%, and 66.4%; major amputation, 0%, 2.9%, and 16.4%; hospitalization, 14.3%, 55.7%, and 89.3%; survival, 100%, 96.7%, and 89.3%. DFU severity was an independent predictor of healing, amputation, hospitalization, and survival. The current study shows an association between the grade of severity of DFUs identified by the fast-track model and the considered outcomes. The fast-track model may be a useful tool for assessing the severity and prognosis of DFUs.

Resource use within a multidisciplinary foot team clinic.

OBJECTIVE: The establishment of multidisciplinary foot team clinics reduces the risk of amputation, but little is known about its resource requirement. This study evaluates the service's resource use for first visit attendees to an established multidisciplinary foot team clinic. METHOD: A retrospective evaluation was performed for new referrals to the clinic over six months, including demographics, resource use and clinical outcome. Data were extracted electronically with retrospective review of electronic clinical notes. RESULTS: A total of 240 first visit attendees were analysed. Mean age was 64±15years, 63% were male, 72% had type 2 diabetes, 16% had type 1 diabetes, 15% had a previous amputation, and 40% had a previous ulceration. Common presentations were ulcers (62%), osteomyelitis (11%), Charcot foot (19%), foot ischaemia (17%), post-surgical wounds (13%), and osteomyelitis (11%). At first attendance, 79% of patients required specialist services including diabetologist (45%), joint vascular review (23%), joint orthopaedics services (8%), dermatologist (2%), and orthotics services (1%). A total of 4% of patients had complex debridement, 0.4% total nail excision, 0.8% pus drainage, 3% cast-related procedures, and 1% vacuum-assisted dressing. Of the patients, 4% were admitted to hospital, 38% had vascular duplex investigations, 7% had a deep vein thrombosis scan, 16% had magnetic resonance imagine (MRI), and 5% had a bone scan. CONCLUSION: A functional multidisciplinary foot team clinic requires significant resources-both clinical and administrative-for prompt investigations and revascularisation to sustain low amputation rates. Regular appraisal of resource use helps with clinic and pathway planning.

Outcomes after Emergency Admission with a Diabetic Foot Attack Indicate a High Rate of Healing and Limb Salvage But Increased Mortality: 18-Month Follow-up Study.

AIM: The diabetic foot attack (DFA) is perhaps the most devastating form of diabetic foot infection, presenting with rapidly progressive skin and tissue necrosis, threatening both limb and life. However, clinical outcome data in this specific group of patients are not available. METHODS: Analysis of 106 consecutive patients who underwent emergency hospitalisation for DFA (TEXAS Grade 3B or 3D and Infectious Diseases Society of America (IDSA) Class 4 criteria). Outcomes evaluated were: 1) Healing 2) major amputation 3) death 4) not healed. The first outcome reached in one of these four categories over the follow-up period (18.4±3.6 months) was considered. We also estimated amputation free survival. RESULTS: Overall, 57.5% (n=61) healed, 5.6% (n=6) underwent major amputation, 23.5% (n=25) died without healing and 13.2% (n=14) were alive without healing. Predictive factors associated with outcomes were: Healing (age<60, p=0.0017; no Peripheral arterial disease (PAD) p= 0.002; not on dialysis p=0.006); major amputation (CRP>100 mg/L, p=0.001; gram+ve organisms, p=0.0013; dialysis, p= 0.001), and for death (age>60, p= 0.0001; gram+ve organisms p=0.004; presence of PAD, p=0.0032; CRP, p=0.034). The major amputation free survival was 71% during the first 12 months from admission, however it had reduced to 55.4% by the end of the follow-up period. CONCLUSIONS: In a unique population of hospitalised individuals with DFA, we report excellent healing and limb salvage rates using a dedicated protocol in a multidisciplinary setting. An additional novel finding was the concerning observation that such an admission was associated with high 18-month mortality, almost all of which was after discharge from hospital.

Peripheral Arterial Disease Located in the Feet of Patients With Diabetes and Foot Ulceration Demands a New Approach to the Assessment of Ischemia.

Peripheral arterial disease (PAD) is common below the knee in diabetes but arteries in the foot are controversially said to be spared of occlusive disease. This is relevant to the convenient site of vascular assessment that is recommended in guidelines. Should assessment be distal at toe/forefoot to detect foot disease or only proximal to detect disease at ankle level? The objective was to determine frequency of PAD at foot and ankle level. This was a cross-sectional observational study, evaluating arterial disease proximally by palpation of pedal pulses and Ankle Brachial Index (ABI), and distally by Toe Brachial Index (TBI), and forefoot transcutaneous oxygen tension (tcpO2), in consecutive patients presenting with foot ulceration. We assessed 301 limbs in 154 patients: 59% of limbs were ulcerated. PAD in the foot was detected in 70% and 74% of limbs by TBI and forefoot tcpO2, respectively, but PAD at ankle level only in 51% and 34% by pulse palpation and ABI, respectively. In limbs with "normal" ABI, PAD was present in the foot in 70% as indicated by low TBI, and in 73% by low tcpO2, with 70% to 64% having associated ulceration, respectively. When compared with arterial waveforms, as a measure of PAD, TBI gave an excellent AUC (area under the curve of the receiver operating characteristic curve) of 0.81 (95% confidence interval: 0.73-0.89), but ABI gave a poor AUC of 0.65 (95% confidence interval: 0.55-0.76). In conclusion, arterial disease is important in the foot and can be detected by TBI, which should be performed even when ABI is normal. Guidelines that recommend TBI only if ABI is artificially raised need updating.

Characteristics of new patient referrals to specialised diabetic foot units across Europe and factors influencing delays.

OBJECTIVE: Foot ulcers are a common complication of diabetes and are associated with an increase in lower limb amputation and death. Early referral to a specialised unit is recommended. The aim of this study was to assess the characteristics of new-patient referrals to specialised diabetes foot care units across Europe and to determine the factors involved in delayed referral. METHOD: In this prospective observational study, consecutive patients with a new foot ulcer presenting to nine diabetic foot centres in five European countries (France, Germany, Italy, Spain and the UK) were included. RESULTS: Some 25% of the 332 patients included had presented with a foot ulcer >3 months before referral to the participating foot clinic. Compared with patients referred earlier, patients with a long time to referral (>3 months) were older (p=0.006) and had a less severe wound according to Infectious Diseases Society of America (IDSA) classification (p=0.003) and University of Texas classification (grade D=infection + peripheral artery disease, p=0.004). CONCLUSION: The proportion of patients with a diabetic foot ulcer (DFU) referred to a specialised unit >3 months after the beginning of the ulcer remained high throughout Europe. Patients with severe DFU were, however, referred more quickly by front line health professionals. Primary care professionals need to be made aware of the importance of early referral to a specialised unit in order to improve the management of foot disease in patients with diabetes. DECLARATION OF INTEREST: The authors have no conflicts of interest to declare.

People living with diabetes are unaware of their foot risk status or why they are referred to a multidisciplinary foot team.

AIM: People with active diabetic foot disease should be rapidly referred by health professionals along a pathway of care to a multidisciplinary foot team. The aim was to investigate patients' self-reported understanding of their foot risk status and reasons for their referral to a multidisciplinary foot team. METHOD: This seven-month service evaluation included consecutive newly referred patients. Participants completed a questionnaire which asked firstly about their understanding of their foot risk status, secondly about their pathway of care before presentation to the multidisciplinary foot team, and thirdly about their interest in diabetes-related foot education and preferred learning style. RESULTS: There were 202 participants; 65% were male, mean age was 64±15 years (mean±standard deviation (SD)), 86% had type 2 diabetes, and mean HbA1c was 65±23mmol/mol (8.3±3.7%). Only 4% of participants knew their current foot risk status and 52% did not know why their care had been escalated to a multidisciplinary foot clinic. Participants with type 2 diabetes more readily expressed an interest in further foot education compared with participants with type 1 diabetes, (70% versus 29%, p=0.001). CONCLUSIONS: These findings show that people with diabetes and foot disease are less aware of their foot risk status or why they are referred to a multidisciplinary team. Participants indicated a variable interest in further learning about foot complications. These findings indicate possible communication and educational barriers between patients and health professionals which may contribute to delayed presentation or suboptimal engagement.

Effectiveness of fast-track pathway for diabetic foot ulcerations.

AIM: To investigate the effectiveness of fast-track pathway (FTP) in the management of diabetic foot ulceration (DFU) after 2 years of implementation. METHODS: The study group was composed of patients who referred to a specialized DF centre due to DFUs. Those were divided in two groups: early referral (ER) and late referral (LR) patients. According to FTP, ER were considered patients who referred after 2 weeks in the case of uncomplicated non-healing ulcers (superficial, not infected, not ischemic), within 4 days in the case of complicated ulcers (ischemic, deep, mild infection) and within 24 h in the case of severely complicated ulcers (abscess, wet gangrene, fever). Healing, healing time, minor and major amputation, hospitalization, and survival were evaluated. The follow-up was 6 months. RESULTS: Two hundred patients were recruited. The mean age was 70 ± 13 years, 62.5% were male, 91% were affected by type 2 diabetes with a mean duration of 18 ± 11 years. Within the group, 79.5% had ER while 20.5% had LR. ER patients showed increased rates of healing (89.9 vs. 41.5%, p = 0.001), reduced healing time (10 vs. 16 weeks, p = 0.0002), lower rates of minor (17.6 vs. 75.6%, p < 0.0001) and major amputation (0.6 vs. 36.6%, p < 0.0001), hospitalization (47.1 vs. 82.9%, p = 0.001), and mortality (4.4 vs. 19.5%, p = 0.02) in comparison to LR. At multivariate analysis, ER was an independent predictor of healing, while LR was an independent predictor for minor and major amputation and hospitalization. CONCLUSION: After the FTP implementation, less cases of LR were reported in comparison to ER. ER was an independent predictor of positive outcomes such as healing, healing time, limb salvage, hospitalization, and survival.

The current burden of diabetic foot disease.

Neuropathy and ischaemia are two great pathologies of the diabetic foot which lead to the characteristic features of foot ulceration (neuropathic and ischaemic) and Charcot neuroarthropathy. These can be complicated by infection and eventually may result in amputation (minor or major) and increased mortality. All of these features contribute to considerable clinical and economic burden. Peripheral nerves in the lower limbs are susceptible to different types of damage in patients with diabetes leading to distinctive syndromes. These include symmetrical sensory neuropathy associated with autonomic neuropathy, which advances gradually, and acutely painful neuropathies and mononeuropathies which have a rather acute presentation but usually recover. Ischaemia in the form of peripheral arterial disease is an important contributor to the burden of the diabetic foot. The incidence of atherosclerotic disease is raised in patients with diabetes and its natural history is accelerated. Diabetes causes severe and diffuse disease below-the knee. The lifetime risk of developing a diabetic foot ulcer is between 19% and 34%. Recurrence is common after initial healing; approximately 40% of patients have a recurrence within 1 year after ulcer healing, almost 60% within 3 years, and 65% within 5 years. Charcot neuroarthropathy is characterised by bone and joint destruction on the background of a neuropathy. Its prevalence in diabetes varies from 0.1% to 8%. Infection develops in 50%-60% of ulcers and is the principal pathology that damages diabetic feet. Approximately 20% of moderate or severe diabetic foot infections result in lower extremity amputations. The incidence of osteomyelitis is about 20% of diabetic foot ulcers. Every 20 s a lower limb is amputated due to complications of diabetes. Of all the lower extremity amputations in persons with diabetes, 85% are preceded by a foot ulcer. The mortality at 5 years for an individual with a diabetic foot ulcer is 2.5 times as high as the risk for an individual with diabetes who does not have a foot ulcer. The economic burden exacted on health care systems is considerable and includes direct and indirect costs, with loss of personal earnings and burden to carers. The diabetic foot is a significant contributor to the global burden of disability and reduces the quality of life. It remains a considerable public health problem.

Isolated low toe-brachial index is associated with increased mortality and morbidity: a retrospective cohort study.

OBJECTIVE: The aim was to assess the prognostic impact of perfusion assessments including ankle-brachial Index (ABI) and toe-brachial Index (TBI) on survival of patients who present with diabetic foot ulceration and to analyse clinical outcomes when patients are categorised into three levels of limb ischaemia. METHOD: This was a retrospective cohort analysis of consecutive patients presenting with foot ulceration. Patients continued with their standard of care, after having baseline assessments of limb perfusion. Patients were retrospectively categorised into three groups according to baseline ABI and TBI: Group 1 (n=31) non-ischaemic (TBI≥0.75, ABI≥0.9), Group 2 (n=67) isolated low TBI with foot ischaemia (TBI<0.75, ABI≥0.90) and Group 3 (n=30) foot-leg ischaemia (TBI<0.75, ABI<0.90). RESULTS: A total of 128 patients took part in the study. Low TBI was associated with a significant decrease in patient survival (42±20 versus 51±16 months, p=0.011). There was a progressive and significant decline in mean patient survival time (51±16 versus 44±20 versus 39±22 months, respectively, for ANOVA across the three groups, p=0.04). Patients with isolated low TBI had angioplasty and bypass at a rate similar to that of patients in Group 3 (low ABI and low TBI). The proportion of angioplasties was significantly higher in the isolated low TBI (19.4% (13/67) versus the non-ischaemic 3.2% (1/31), p=0.033). Such revascularisation resulted in ulcer healing within the foot ischaemic group that was similar to the non-ischaemic group (68% versus 60% over 12 months, p=0.454). CONCLUSION: Regardless of ABI level, measurement of TBI identifies patients with isolated low TBI who require specialised care pathways and revascularisation to achieve ulcer healing that is similar to non-ischaemic patients.

The Role of Bone Scintigraphy with SPECT/CT in the Characterization and Early Diagnosis of Stage 0 Charcot Neuroarthropathy.

We describe the use of Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) in the investigation and diagnosis of Charcot neuroarthropathy (CN) in patients with a hot swollen foot but normal radiographs and clinical suspicion of CN, usually termed Stage 0. This was a retrospective cohort review of 46 diabetes patients who underwent 3 phase bone scintigraphy with "High Resolution" SPECT/CT. The imaging demonstrated that Stage 0 Charcot foot has a distinct bone pathology, which can be classified into three groups: (1) fractures on Computed Tomography (CT) with accompanying focal uptake of tracer on SPECT, (2) bony abnormalities apart from fracture on CT with focal uptake of tracer on SPECT, and (3) normal CT but focal bony uptake of tracer on SPECT. The CT component of SPECT/CT detected bony fractures in 59% of patients. Early treatment with below knee cast and follow-up for 24 months showed only 4 patients who developed Stage 1 Eichenholtz Charcot foot. Our findings support the use of 3 phase bone scintigraphy with SPECT/CT in the characterization and early diagnosis of CN. Stage 0 Charcot foot has a distinct bone pathology which requires urgent treatment to prevent progression to Stage 1 Eichenholtz Charcot foot. If SPECT/CT is unavailable, CT alone will detect bone fracture in 59% patients.

Referral of patients with diabetic foot ulcers in four European countries: patient follow-up after first GP visit.

OBJECTIVE: This study aimed to analyse the characteristics of patients, including demographics, medical history and treatment, with a diabetic foot ulcer (DFU) during their first follow-up visit to a general practitioner (GP). METHODS: A two-part quantitative online questionnaire was distributed among GPs in France, UK, Germany and Spain. Part one entailed a survey of GPs' perceptions of referrals for DFU. Part two collected data on recently managed DFU cases. The percentage of responses was compared for each question and across the four countries for significant differences. RESULTS: In part one of the study, 600 questionnaires were collected (150 per country) and 1188 patients managed for a DFU were included in the second part. About 88% of patients had type 2 diabetes, with a significant proportion of suboptimal control (average HbA1c: 10.64mmol/l). A patient complaint led to diagnosis in 60% of the cases. Wounds were found to be more frequently located in the toes and midfoot, and were superficial (according to the Texas Wound Classification system) in 80% of the cases. More than two-thirds of patients developed small wounds (<5cm2); more than half of them had infected wounds. Approximately 50% of wounds were ischaemic, which triggered the onset of a DFU. Follow-up wound examinations before and after hospitalisation were performed by nurses, except in Germany where GPs undertook this role, including prescribing offloading devices and in the UK where follow-up was managed by podiatrists. Ischaemia, wound necrosis, suspected osteomyelitis and absence of wound healing were the primary reasons for hospital admission during the first month after diagnosis. CONCLUSION: Delay in specialised foot care is a recurring topic in the treatment of DFUs, even with different health-care structures across Europe. Knowledge and education on DFUs should be reinforced among GPs and nurses to establish a global DFU care network between primary and specialised care, avoid hospitalisation and adequately manage high-risk patients.

Surgical Diabetic Foot Debridement: Improving Training and Practice Utilizing the Traffic Light Principle.

Comprehensive management of a severe diabetic foot infection focus on clear treatment pathways. Including rapid, radical debridement of all infection in addition to intravenous antibiotics and supportive measures. However, inexperienced surgeons can often underestimate the extent of infection, risking inadequate debridement, repeated theatre episodes, higher hospital morbidity, and hospital length of stay (LOS). This study aims to assess protocolized diabetic-foot-debridement: Red-Amber-Green (RAG) model as part of a value-based driven intervention. The model highlights necrotic/infected tissue (red-zone, nonviable), followed by areas of moderate damage (amber-zone), healthy tissue (green-zone, viable). Sequential training of orthopedic surgeons supporting our emergency service was undertaken prior to introduction. We compared outcomes before/after RAG introduction (pre-RAG, n = 48; post- RAG, n = 35). Outcomes measured included: impact on number of debridement/individual admission, percentage of individuals requiring multiple debridement, and length-of-hospital-stay as a function-of-cost. All-patients fulfilled grade 2/3, stage-B, of the Texas-Wound-Classification. Those with evidence of ischemia were excluded. The pre-RAG-group were younger (53.8 ± 11.0 years vs 60.3 ± 9.2 years, P = .01); otherwise the 2-groups were matched: HbA1c, white blood cell count, and C-reactive protein. The post-RAG-group underwent significantly lower numbers of debridement's (1.1 ± 0.3 vs 1.5 ± 0.6/individual admission, P = .003); equired fewer visits to theatre (8.6% vs 38%, P = .003), their LOS was reduced (median LOS pre-RAG 36.0 vs post-RAG 21.5 days, P = .02). RAG facilitates infection clearance, fewer theatre-episodes, and shorter LOS. This protocolized-management-tools in acute severely infected diabetic foot infection offers benefits to patients and health-care-gain.

Perception of diabetic foot ulcers among general practitioners in four European countries: knowledge, skills and urgency.

OBJECTIVE: Diabetic foot ulcers (DFU) have the potential to deteriorate rapidly, in the absence of prompt assessment and treatment. The aim of this study was to analyse the awareness and perception of DFU among general practitioners (GPs) from four European countries, and to find possible differences between these countries in terms of management. METHOD: A two-part, quantitative, online questionnaire was distributed to GPs across four countries in Europe-the UK, France, Germany and Spain. The first part entailed a survey on the perception and knowledge of the pathogenesis and management of DFU, among GPs. The second part of the questionnaire was used for the collection of data on recently-managed DFU cases. RESULTS: For the first part of the study, 600 questionnaires were collected (150 per country) and 1188 patient cases of DFU management were included in the second part. In France, only 49% of GPs mentioned neuropathy as the main causative process in DFU development. However, in Germany and the UK, 82% and 83% of GPs, respectively, considered neuropathy as an important causative factor. DFU care in Spain and the UK is thought to be organised by multidisciplinary teams (MDT) (83% and 84% of GPs, respectively, completely agreed with this statement). In France and Germany, GPs are responsible for follow-up and management. Only UK physicians have clearly identified specialised podiatrists to refer patients to, if needed. Approximately 29-40% of GPs in all countries did not feel they were sufficiently trained in the DFU treatment protocol. Almost 30% of GPs in France and Germany thought that DFU treatment was not well-established due to the absence of clinical guidelines and protocols. CONCLUSION: The intra-country and inter-country management of the complex aspects of DFU is quite heterogeneous. The cause of this finding is multifactorial. Although there are international guidelines, it would be beneficial to establish clear and specific competencies for the different health professionals involved in DFU management. As a minimum, intra-country heterogeneity should improve with their development.

Using a modified Delphi methodology to gain consensus on the use of dressings in chronic wounds management.

OBJECTIVE: Managing chronic wounds is associated with a burden to patients, caregivers, health services and society and there is a lack of clarity regarding the role of dressings in improving outcomes. This study aimed to provide understanding on a range of topics, including: the definition of chronicity in wounds, the burden of illness, clinical outcomes of reducing healing time and the impact of early interventions on clinical and economic outcomes and the role of matrix metalloproteinases (MMPs) in wound healing. METHOD: A systematic review of the literature was carried out on the role of dressings in diabetic foot ulcer (DFU), and venous leg ulcer (VLU) management strategies, their effectiveness, associated resource use/cost, and quality of life (QoL) impact on patients. From this evidence-base statements were written regarding chronicity in wounds, burden of illness, healing time, and the role of MMPs, early interventions and dressings. A modified Delphi methodology involving two iterations of email questionnaires followed by a face-to-face meeting was used to validate the statements, in order to arrive at a consensus for each. Clinical experts were selected, representing nurses, surgeons, podiatrists, academics, and policy experts. RESULTS: In the first round, 38/47 statements reached or exceeded the consensus threshold of 80% and none were rejected. According to the protocol, any statement not confirmed or rejected had to be modified using the comments from participants and resubmitted. In the second round, 5/9 remaining statements were confirmed and none rejected, leaving 4 to discuss at the meeting. All final statements were confirmed with at least 80% consensus. CONCLUSION: This modified Delphi panel sought to gain clarity from clinical experts surrounding the use of dressings in the management of chronic wounds. A full consensus statement was developed to help clinicians and policy makers improve the management of patients with these conditions.

Delayed referral of patients with diabetic foot ulcers across Europe: patterns between primary care and specialised units.

OBJECTIVE: Diabetic foot ulceration (DFU) has the potential to deteriorate rapidly without prompt assessment and treatment. The aim of this study was to assess the referral patterns for DFU, from primary care to specialised diabetes foot care units. METHOD: A two-part, quantitative, online questionnaire was administered to GPs across four countries in Europe: France, the UK, Germany and Spain. The first part entailed a survey of GPs' perceptions of referrals for DFU. The second part of the questionnaire collected data on recently managed DFU cases. RESULTS: There were 600 questionnaires collected in the first part of the study (150 per country), and 1188 patient cases of DFU management were included in the second part. Up to 95% of patients had type 2 diabetes. Patients' complaints led to diagnosis, on average, 60% of the time, and the diagnosis was an incidental finding during a consultation 13-28% of the time. On average, only 40% of GPs completely agreed that they have clearly identified DFU clinical practitioners working in a hospital facility. In 55-66% of cases, the duration of DFU was unknown or DFU diagnosis was delayed more than three weeks from the onset of the wound. On average, 48% of patients were referred after an unknown duration or more than one month from the onset of DFU. CONCLUSION: Despite differences in health-care structures across Europe, delays in referral to specialist foot care teams seems to be a common theme. There is an ongoing need to educate GPs, nurses and patients to be more aware of the risk of DFU, and the need for prompt referral to specialist diabetic foot teams.

Transformation of the multidisciplinary diabetic foot clinic into a multidisciplinary diabetic foot day unit: results from a service evaluation.

The natural history of the diabetic foot is aggressive and complex. To counteract this, we describe the transformation of a Multidisciplinary Diabetic Foot Clinic into a Multidisciplinary Diabetic Foot Day Unit, which delivers an emergency open access system for patients, with a "one-stop," same day service in which investigations are performed, results reviewed and treatment implemented. It also provides joint clinics with vascular, orthopaedic, and plastic surgeons and specialized clinics for casting of complex neuropathic feet and for the administration of intravenous or intramuscular antibiotics on the same day. The aim was to document these increasingly wide-ranging facilities by undertaking a retrospective evaluation over a 6-week period, with analysis of notes, investigations, and an anonymous patient satisfaction survey. The clinic was visited by 597 patients who attended in 1076 appointments, of which 112 (10.4%) were emergency visits; these patients attended the clinic without a booked appointment but via an open access policy, 93 of whom were known to the clinic, but 19 were new self-referred patients to the service. Furthermore, 197 (18%) were seen in a Joint Vascular Diabetic Foot Clinic and 98 (9%) were seen in a Joint Orthopaedic Plastic Diabetic Foot Clinic, 570 (53%) were seen in an Active Ulcer Clinic and 97 (9%) in a Total Contact Casting Clinic. Forty-five percent of patients were prescribed antibiotics, including 188 (76%) as oral and 45(18%) as intravenous antibiotics and 15(6%) as intramuscular injections. Of the 1076 appointments, 150 (14%) patients were in the foot clinic for more than 4 hours. Sixty (10%) patients were reviewed 4 or more times over the 6-week period. Only 22 (2%) were admitted to hospital. Of the 125 survey responders, 98% were satisfied with this service, which has evolved from a Diabetic Foot Clinic into a Multidisciplinary Diabetic Foot Day Unit.
