Ntuli S, Letswalo DM. Diabetic foot and lower limb amputations at central, provincial and tertiary hospitals-underscores the need for organised foot health services at primary healthcare level. Foot (Edinb) 2023; 56:102039. [PMID: 37244198 DOI: 10.1016/j.foot.2023.102039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 04/13/2023] [Accepted: 05/06/2023] [Indexed: 05/29/2023]
Abstract
BACKGROUND Diabetic foot amputations are a devastating outcome for any diabetic patient. They are associated with various risk factors, including failure to risk stratify the diabetic foot. Early risk stratification could lower foot complications risk at the primary healthcare level (PHC). In the Republic of South Africa (RSA), PHC clinics are the first entry point to the public healthcare system. Failure to correctly identify, risk categorise, and refer diabetic foot complications at this level may lead to poor clinical outcomes for diabetic patients. This study looks at the incidence of diabetic-related amputations at central and tertiary hospitals in Gauteng to highlight the case of the needed foot health services at the PHC level. METHODS A cross-sectional retrospective study that reviewed prospectively collected theatre records database of all patients who underwent a diabetic-related foot and lower limb amputation between January 2017 and June 2019. Inferential and descriptive statistics were performed, and patient demographics, risk factors and type of amputation were reviewed. RESULTS There were 1862 diabetic-related amputations in the period under review. Most patients (98 %) came from a poor socioeconomic background earning ZAR 0.00-70 000.00 (USD 0.00-4754.41) per annum. Most amputations, 62 % were in males, and the majority, 71 % of amputations, were in patients younger than 65. The first amputation was major in 73 % of the cases, and an infected foot ulcer was a primary amputation cause in 75 % of patients. CONCLUSION Amputations are a sign of poor clinical outcomes for diabetic patients. Due to the hierarchal nature of healthcare delivery in RSA, diabetic-related foot amputations could imply inadequate care of or access to diabetic foot complications at the PHC level in RSA. A lack of access to structured foot health services at PHC levels impedes early identification of foot complication identification and appropriate referral resulting in amputation in some of the patients.

The Development of Lower Limb Amputations in Finland from 1997 to 2018: A Nationwide Retrospective Registry Study. Eur J Vasc Endovasc Surg 2021; 63:138-146. [PMID: 34774371 DOI: 10.1016/j.ejvs.2021.09.030] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 08/25/2021] [Accepted: 09/19/2021] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To investigate the rates of transfemoral, transtibial foot and toe amputations, and lower limb revascularisations in Finland between 1997 and 2018. METHODS Retrospective observational cohort study. Data from the Finnish National Hospital Discharge Register for the period 1997 - 2018 were used. The study population covered all patients 20 years and older who underwent lower limb revascularisations or amputations in private and public hospitals during the study period. All (outpatient and inpatient) amputations and revascularisations were included. The age adjusted incidence rates were based on the annual mid populations, which were obtained from the Official Statistics of Finland. Continuous variables were presented as median with interquartile range (IQR) or as mean with standard deviation. The 95% confidence intervals (CI) for the incidence rates were calculated using the Poisson exact method. All changes in incidence were calculated as relative change (%). RESULTS A total of 75 230 patients underwent 149 492 lower limb revascularisations and amputations between 1997 and 2018 in Finland. The median (IQR) age of the patients was 73 (65, 80) and 60% of the patients were men. The incidence of all endovascular lower limb revascularisations increased by 159% while the incidence of lower limb amputations increased by 25%. The most notable increase occurred in toe (84%) and foot (107%) amputations, while the incidence of transfemoral amputations remained steady and transtibial amputations decreased by 53%. The first minor-major amputation ratio (CI) increased from 1.13 (1.03 - 1.24) to 1.49 (1.36 to 1.62) during the study period. CONCLUSION The findings of this nationwide cohort study suggest that the incidence of both lower limb revascularisations and amputations is increasing. More specifically, revascularisations are more often performed endovascularly, and the incidence of transtibial amputations is declining, whereas the incidence of toe and foot amputations is increasing.

Abstract
INTRODUCTION Topical oxygen therapy (TOT) has been suggested as a treatment for diabetes-related foot ulcer (DFU) but no prior meta-analyses of randomised clinical trials (RCT) have been reported. This systematic review and meta-analysis examined the randomised evidence for the benefit of TOT in healing DFU. METHODS Publicly available databases were searched for RCTs investigating the effect of TOT on wound healing in participants with a DFU. The primary outcome was ulcer healing defined as full epithelialisation. Meta-analyses were performed using random effect models and reported as risk ratios (RR) and 95% confidence intervals (CI). Study quality and publication bias were assessed using a modified version of the Cochrane Collaboration's tool and funnel plots, respectively. RESULTS Six RCTs involving 530 participants with a DFU testing TOT were included. Meta-analysis suggested that TOT significantly increased the likelihood of ulcer healing compared to controls (Risk ratio [RR] 1.94; 95% CI 1.19, 3.17; I2 = 57%; NNT = 5.33) and findings were robust in sensitivity analyses. Risk of bias was high, moderate and low in two, one and three studies, respectively. Analysis of the three trials judged to be at low risk of bias suggested that TOT increased the likelihood of ulcer healing compared to controls (RR 2.37; 95% CI 1.52, 3.68; I2 = 0%). Funnel plots suggested the possibility of publication bias. Data on amputation were too limited for meta-analysis. CONCLUSION This meta-analysis suggests that TOT improves the likelihood of DFU healing; however, its effect on amputation and cost-effectiveness are unclear.

Abstract
Diabetic foot is a major public health issue, driven by diabetes complications (neuropathy, peripheral vascular disease, foot deformity, and abnormal leucocyte function), which may lead to leg amputation, thus resulting in severe disability, reduced quality of life, and high health costs. The prevention of diabetes complications and the early detection and proper management of diabetic foot wounds are the milestones to avoid major amputations. Unfortunately, in many areas, the prevention of diabetic foot lesions is inadequate and wounds may proceed toward infection and chronicity, with limb- and life-threatening results. Using the Delphi method, we conducted a survey on diabetic foot among Italian experts, selected across different Italian clinical centers. This method was used to achieve a consensus on current opinion and clinical leanings on the diagnosis and management of diabetic foot ulcers. Specifically, the aim of the survey was to evaluate the current management of the diabetic foot syndrome; highlight the differences in the approach among a group of experts; evaluate the role of wound bed preparation and antisepsis; and discuss any areas of disagreement in which evidences are sparse and the clinical judgment plays a crucial role in the decision-making process.

Abstract
BACKGROUND Above-knee amputation (AKA) is a morbid procedure and is performed for a number of conditions. Although AKA is usually performed for dysvascular disease, trauma, and malignancy, AKA is also considered in patients who have failed multiple salvage attempts at treating periprosthetic joint infection (PJI) of TKA. Although aggressive measures are being taken to treat PJI, the huge volume of TKAs might result in a large number of AKAs being performed for PJI in the United States. However, the national trends in the incidence of AKAs from different etiologies and the relative contribution of different etiologies to AKA are yet to be studied. QUESTIONS/PURPOSES (1) What are the temporal trends in the incidence of AKAs (from all causes) in the US population from 1998 to 2013? (2) What are the temporal trends in the incidence of AKAs by etiology (dysvascular disease, trauma, malignancy, and PJI)? (3) What are the temporal trends in the relative contribution of different etiologies to AKA? METHODS Using the Nationwide Inpatient Sample (NIS) from 1998 to 2013, AKAs were identified using International Classification of Diseases, 9 Revision (ICD-9) procedure code 84.17. The NIS database is the largest all-payer database in the United States containing information on approximately 20% of all the hospital admissions in the country. As a result of its sampling design, it allows for estimation of procedural volumes at the national level. All AKAs were grouped into one of the following five etiologies in a sequential manner using ICD-9 diagnosis codes: malignancy, PJI, trauma, dysvascular disease (peripheral vascular disease, diabetic, or a combination), and others. All of the numbers were converted to national estimates using sampling weights provided by the NIS, and the national incidence of AKAs resulting from various etiologies was calculated using the US population as the denominator. Poisson and linear regression analyses were used to analyze the annual trends. RESULTS From 1998 to 2013, the incidence of AKAs decreased by 47% from 174 to 92 AKAs per 1 million adults (incidence rate ratio [IRR]; change in the number of AKAs per 1 million adults per year; 0.96; 95% confidence interval [CI], 0.96-0.96; p < 0.001). The incidence of AKAs resulting from PJI increased by 263% (IRR, 1.07; 95% CI, 1.06-1.07; p < 0.001). An increase was also observed for AKAs from malignancy (IRR, 1.01; 95% CI, 1.00-1.02; p = 0.007), although to a smaller extent. AKAs from dysvascular causes (IRR, 0.96; 95% CI, 0.95-0.96; p < 0.001) and other etiologies (IRR, 0.97; 95% CI, 0.96-0.97; p < 0.001) decreased. There was no change in the incidence of AKAs related to trauma (IRR, 1.00; 95% CI, 0.99-1.00; p = 0.088). The proportion of AKAs resulting from PJI increased by 589% from 1998 to 2013 (coefficient = 0.18; 95% CI, 0.15-0.22; p < 0.001). The proportion of AKAs resulting from dysvascular causes decreased (coefficient = 0.18; 95% CI, 0.15-0.22; p < 0.001), whereas that resulting from malignancy (coefficient = 0.04; 95% CI, 0.03-0.05; p < 0.001) and trauma (coefficient = 0.13; 95% CI, 0.09-0.18; p < 0.001) increased. CONCLUSIONS The incidence of AKAs has decreased in the United States. AKAs related to dysvascular disease and other etiologies such as trauma and malignancy have either substantially decreased or remained fairly constant, whereas that resulting from PJI more than tripled. Given the increased resource utilization associated with limb loss, the results of this study suggest that national efforts to reduce disability should prioritize PJI. Further studies are required to evaluate the risk factors for AKA from PJI and to formulate better strategies to manage PJI. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Lower extremity amputation (LEA) in patients with diabetes results in high mortality, reduced quality of life, and increased medical costs. Exact data on incidences of LEA in diabetic and non-diabetic patients are important for improvements in preventative diabetic foot care, avoidance of fatal outcomes, as well as a solid basis for health policy and the economy. However, published data are conflicting, underlining the necessity for the present systematic review of population-based studies on incidence, relative risks and changes of amputation rates over time. It was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Nineteen out of 1582 studies retrieved were included in the analysis. The incidence of LEA in the diabetic population ranged from 78 to 704 per 100,000 person-years and the relative risks between diabetic and non-diabetic patients varied between 7.4 and 41.3. Study designs, statistical methods, definitions of major and minor amputations, as well as the methods to identify patients with diabetes differed greatly, explaining in part these considerable differences. Some studies found a decrease in incidence of LEA as well as relative risks over time. This obvious lack of evidence should be overcome by new studies using a standardized design with comparable methods and definitions.

Abstract
BACKGROUND/AIM Diabetic foot ulcers and related complications are a major cause of morbidity and hospital admissions. Our aim was to evaluate the risk factors associated with poor outcome in diabetic foot ulcers. MATERIALS AND METHODS A prospective study was conducted on patients with diabetic foot ulceration attending the Madinah Teaching Hospital from June 2014 to December 2015. Potential risk factors and laboratory test results at presentation were recorded and their association with outcome (healing vs. amputation) was analyzed using IBM SPSS Statistics for Windows, Version 22.0. RESULTS In total, 112 patients were studied during our study period. The majority of the patients were male (60.7%) and aged 50 years and older (62.5%). Regarding the outcome, 68% healed completely, 27.7% underwent amputation, and 4.5% died during this period. Patient age of 50 and older, long duration of diabetes (>10 years), rural origin, and heel ulcers were significantly associated with poor outcome (P < 0.05). CONCLUSION Patients with diabetes should have a detailed annual foot examination; those having risk factors for poor outcome require more frequent foot care, patient education, and early referral to tertiary care centers.

Abstract
Background: Plantar pressure serves as a key factor for predicting ulceration in the feet of diabetes patients. We designed this study to analyze plantar pressure changes and correlating risk factors in Chinese patients with type 2 diabetes. Methods: We recruited 65 patients with type 2 diabetes. They were invited to participate in the second wave 2 years later. The patients completed identical examinations at the baseline point and 2 years later. We obtained maximum force, maximum pressure, impulse, pressure-time integral, and loading rate values from 10 foot regions. We collected data on six history-based variables, six anthropometric variables, and four metabolic variables of the patients. Results: Over the course of the study, significant plantar pressure increases in some forefoot portions were identified (P < 0.05), especially in the second to forth metatarsal heads. Decreases in heel impulse and pressure-time integral levels were also found (P < 0.05). Plantar pressure parameters increased with body mass index (BMI) levels. Hemoglobin A1c (HbA1c) changes were positively correlated with maximum force (β = 0.364, P = 0.001) and maximum pressure (β = 0.366, P = 0.002) changes in the first metatarsal head. Cholesterol changes were positively correlated with impulse changes in the lateral portion of the heel (β = 0.179, P = 0.072) and pressure-time integral changes in the second metatarsal head (β = 0.236, P = 0.020). Ankle-brachial index (ABI) changes were positively correlated with maximum force changes in the first metatarsal head (β = 0.137, P = 0.048). Neuropathy symptom score (NSS) and common peroneal nerve sensory nerve conduction velocity (SCV) changes were positively correlated with some plantar pressure changes. In addition, plantar pressure changes had a correlation with the appearance of infections, blisters (β = 0.244, P = 0.014), and calluses over the course of the study. Conclusions: We should pay attention to the BMI, HbA1c, cholesterol, ABI, SCV, and NSS changes in the process of preventing high plantar pressure and ulceration. Some associated precautions may be taken with the appearance of infections, blisters, and calluses.

Abstract
High plantar pressures are a risk factor for diabetic foot ulcers that are common chronic wounds. In patients with peripheral neuropathy, plantar ulcers may be managed by debridement of callus, a process that has been shown to reduce peak plantar pressures. Callus debridement is clearly an important ulcer prevention strategy. The scalpel skills used by the podiatrist to remove callus are best suited to achieve safe, local sharp wound debridement. Current podiatric practice in the United Kingdom is based on sound theoretical principles. However, good scientific data recommending its efficacy are scarce. The role of podiatry in debridement and wound management needs careful examination, a major aim of this article.

Abstract
AIM To study toe ulcer healing in patients with diabetic foot ulcers attending a multidisciplinary foot clinic over a 10 years period. METHODS The study was retrospective, consecutive and observational during 2001 through 2011. The patients were treated according to the International Consensus on the Diabetic Foot. During the period the chiropodist staffing in the foot clinic was doubled; new offloading material and orthopedic foot corrections for recalcitrant ulcers were introduced. Healing was investigated in toe ulcers in Cox regression models. RESULTS 2634 patients developed foot ulcers, of which 1461 developed toe ulcers; in 790 patients these were neuropathic, in 551 they were neuro-ischemic and in 120 they were critically ischemic. One-year healing rates increased in the period 2001-2011 from 75% to 91% for neuropathic toe ulcers and from 72% to 80% for neuro-ischemic toe ulcers, while no changes was observed for ischemic toe ulcers. Adjusted for changes in the patient population, the overall rate of healing for neuropathic and neuro-ischemic toe ulcers almost doubled (HR=1.95 [95% CI: 1.36-2.80]). CONCLUSION The results show that the healing of toe ulcers improved. This outcome could not be explained by changes in the patient characteristics, but coincided with a number of improvements in organization and therapy.

Syst Rev 2015; 4:74.

Abstract
BACKGROUND Diabetic individuals have a largely increased risk of lower extremity amputation (LEA) compared with non-diabetic patients. Prior systematic reviews of incidence of LEA have some limitations with respect to lack of consensus in the definition of LEA, level of LEA (all, major, minor), and definition of source population (general population or population with diabetes at risk). The purpose of our review is to evaluate the incidence of LEA in the diabetic population and its differences with regard to sex, ethnicity, age, and regions; to compare the incidence rate (IR) in the diabetic and non-diabetic population; and to investigate time trends. METHODS/DESIGN We will perform a systematic literature search in MEDLINE, Embase, Web of Knowledge, and publisher databases such as Journals@OVID and ScienceDirect. We will develop comprehensive systematic search strategies according to established guidelines for meta-analyses of observational studies in epidemiology (the MOOSE group). Two authors will independently screen abstracts and full text of all references on the basis of inclusion criteria with respect to types of study, types of population, and the main outcome. We will exclude studies if they report solely incidences of LEA among persons with diabetes mellitus when referring to the total population (diabetic and non-diabetic) and not exclusively to the diabetic population. Data extraction and assessment of risk of bias will be undertaken by two review authors working independently. We will assess incidence rate (IR) or cumulative incidence (CumI), relative risk of amputations comparing the diabetic to non-diabetic populations, cause of LEA, and type of diabetes. If we find subsets of studies to be homogeneous enough, we will perform meta-analyses for incidence rates by Poisson generalized linear mixed models (GLMM). SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42015017809.

Abstract
BACKGROUND Ulceration of the feet, which can result in loss of limbs and even death, is one of the major health problems for people with diabetes mellitus. OBJECTIVES To assess the effects of patient education on the prevention of foot ulcers in patients with diabetes mellitus. SEARCH METHODS We searched The Cochrane Wounds Group Specialised Register (searched 03 September 2014); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 8). SELECTION CRITERIA Prospective randomised controlled trials (RCTs) that evaluated educational programmes for preventing foot ulcers in people with diabetes mellitus. DATA COLLECTION AND ANALYSIS Two review authors independently undertook data extraction and assessment of risk of bias. Primary end points were foot ulceration or ulcer recurrence and amputation. MAIN RESULTS Of the 12 RCTs included, the effect of patient education on primary end points was reported in only five. Pooling of outcome data was precluded by marked, mainly clinical, heterogeneity. One of the RCTs showed reduced incidence of foot ulceration (risk ratio (RR) 0.31, 95% confidence interval (CI) 0.14 to 0.66) and amputation (RR 0.33, 95% CI 0.15 to 0.76) during one-year follow-up of diabetes patients at high risk of foot ulceration after a one-hour group education session. However, one similar study, with lower risk of bias, did not confirm this finding (RR amputation 0.98, 95% CI 0.41 to 2.34; RR ulceration 1.00, 95% CI 0.70 to 1.44). Three other studies, also did not demonstrate any effect of education on the primary end points, but were most likely underpowered. Patients' foot care knowledge was improved in the short term in five of eight RCTs in which this outcome was assessed, as was patients' self-reported self-care behaviour in the short term in seven of nine RCTs. Callus, nail problems and fungal infections improved in only one of five RCTs. Only one of the included RCTs was at low risk of bias. AUTHORS' CONCLUSIONS In some trials, foot care knowledge and self reported patient behaviour seem to be positively influenced by education in the short term. Yet, based on the only two sufficiently powered studies reporting the effect of patient education on primary end points, we conclude that there is insufficient robust evidence that limited patient education alone is effective in achieving clinically relevant reductions in ulcer and amputation incidence.

Comparison of plantar pressure in three types of insole given to patients with diabetes at risk of developing foot ulcers - A two-year, randomized trial. JOURNAL OF CLINICAL AND TRANSLATIONAL ENDOCRINOLOGY 2014; 1:121-132. [PMID: 29159093 PMCID: PMC5685010 DOI: 10.1016/j.jcte.2014.06.002] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/21/2013] [Revised: 06/04/2014] [Accepted: 06/15/2014] [Indexed: 12/30/2022]
Abstract
Background Special insoles and shoes designed to prevent foot ulcers caused by repetitive high pressures are recommended for patients with diabetes who have any of the following risk factors: neuropathy; peripheral vascular disease; foot deformities; previous ulcers; amputation; and skin pathologies. However, there is a need for increased knowledge regarding: a) differences in the peak pressure (PP) and pressure time integral (PTI) for different types of insoles; and b) the properties of the pressure distribution for insoles used over a period of several months. We present the results of a randomized trial to compare the plantar pressures of three commonly used insoles. Objectives The primary objective was to compare the PP and PTI between three types of insoles. The secondary objective was to explore the long-term pattern of peak plantar pressure distribution and variations in specific regions of interest (ROI). The tertiary objective was to investigate the impacts of insole adjustments, how much the insoles were used, and the levels of patient satisfaction. Methods In a 2-year trial, 114 patients with type 1 (N = 31) or type 2 (N = 83) diabetes (62 men and 52 women; mean age, 57.7 ± 15.4 years; duration of diabetes, 12.3 ± 11.2 years; neuropathy, 38%), were randomized to be supplied with one of three different insoles. The ethylene vinyl acetate (EVA) insoles were used in outdoor walking shoes. The 35 EVA group (N = 39) received soft custom-made insoles composed of EVA of 35 shore A hardness, the 55 EVA group (N = 37) received custom-made insoles composed of EVA of 55 shore hardness, and the control group (N = 38) received prefabricated insoles composed of a hard core with a top layer of soft 12 shore hardness microfiber. Using F-Scan®, the in-shoe plantar pressures were measured at seven ROI (hallux, metatarsal head 1, metatarsal head 2, metatarsal head 4, metatarsal head 5, lateral aspect of the mid-foot, heel) on five occasions during the study period. The plantar-pressure variables used were PP (main outcome) and PTI. The plantar patterns of load were explored, satisfaction and usage of the insoles were rated by the participants, and insole adjustments were recorded. Results A mixed model analysis estimated lower PP values in the heel regions for the 35 EVA and 55 EVA insoles (171 ± 13 and 161 ± 13 kPa, respectively) than for the prefabricated insoles (234 ± 10 kPa) (p < 0.001). Also for some of the other six ROI indications of difference in PP or PTI could be observed. The redistribution of peak plantar pressure for all of the insoles, was stable at the mid-foot, while the proportion of load on the distal area changed during the study period According to the self-reported answers (scale, 0–100), the average usage of the insoles was rated as 79 and satisfaction was rated as 85 (N = 75). Thirty-two percent of the subjects had not received foot care. Fourteen adjustments to insoles were made during the study period, and 86 pairs of insoles were exchanged due to wear, with 49% being exchanged in the 35 EVA group. Conclusions Custom-made insoles used in combination with stable walking shoes gave lower pressures at the heel region. The variation makes it difficult to detect a systematic difference in plantar pressure for the 6 ROI, if such a difference indeed exists. The levels of satisfaction and usage for all the insoles tested were high. The insoles maintained their pressure redistribution properties over long periods, and few adjustments were needed.

Abstract
BACKGROUND Plantar pressure is a key factor for predicting ulceration in the foot of a diabetes patient. SUBJECTS AND METHODS We recruited a group of 100 Chinese patients with type 2 diabetes and an age-, sex-, weight-, and height-matched group of 100 Chinese subjects without diabetes. We obtained plantar pressure data using a Footscan(®) gait system (RsScan International, Olen, Belgium) when the subjects with and without diabetes walked barefoot across a sensor platform. We recorded the maximum force, maximum pressure, impulse, pressure-time integral, and loading rate from 10 regions of the foot. We collected the data of 11 history-based variables, 10 anthropometric variables, and three metabolic variables regarding the clinical characteristics of the diabetes patients. RESULTS Weight was identified as a determining factor for high plantar pressure. Height, the Neuropathy Symptom Score (NSS), and ankle-brachial index (ABI) were correlated positively with plantar pressure measurements, respectively. The sex, history of ulcer and callus, intima-media membrane of the lower limb blood vessels, and fasting blood glucose (FBG) could also explain a portion of the variability of the plantar pressure measurements. However, the correlations were low or weak. CONCLUSIONS High plantar pressure in diabetes patients could be predicted, in part, based on weight, height, NSS, ABI, sex, history of ulcer and callus, intima-media membrane of the lower limb blood vessels, and FBG. Therefore, interventions should be taken specifically before high plantar pressure emerges.

Abstract
AIMS AND OBJECTIVES To survey the efficacy of education about factors that influence the learning process and behaviour of diabetics following a nursing interventional project in diabetic foot care education. BACKGROUND Educating diabetics can change their behaviour, which may contribute to the prevention of diabetic foot ulcer and amputation. However, there is little information on the factors that contribute to effectiveness of foot care education. DESIGN Survey. METHODS The data before education were collected by using structured assessment based on a practical reasoning scheme. The interventional diabetic foot care education project immediately followed. We used verbal and written patient education material. After education (six months), we used a questionnaire by postadministration. The data were analysed using content analysis, descriptive statistics and inferential statistics. RESULTS We discovered a rise of knowledge, willingness and motivation to learn and to change the behaviour of diabetics after education. The clinical parameters (weight, Body Mass Index, blood pressure) demonstrated a statistically significant positive change six months after education. CONCLUSION The findings after education show a rise in knowledge, willingness and motivation, which are important factors that contribute to changing behaviour of diabetics in diabetic foot care. After education, we identified better results in terms of weight and blood pressure, both of which play a role in the prevention of diabetic ulcer. RELEVANCE TO CLINICAL PRACTICE The education valuable tool ensures knowledge, motivation and willingness to change behaviour in order to prevent diabetic foot complications of diabetics. By using structured assessment, nurses are able to modify their educational interventions.

Abstract
Treatment of diabetic foot ulceration is very challenging, costly and often needs to be of long duration. This leads to substantial economic burden. Population-based research suggests that a meaningful reduction of the incidence of amputations caused by diabetes mellitus has already been achieved since the St. Vincent resolution in 1989. Still, it cannot be inferred from these studies that the current preventive efforts are (cost-)effective because reduction of amputation incidence can also be the result of improvements in ulcer treatment. Nevertheless, education of people with diabetes is widely advocated and implemented in standard practice. Despite the fact that preventive interventions are often combined in daily practice, there is little scientific evidence demonstrating the effect of those efforts. In systematically reviewing the evidence, there is insufficient evidence that limited patient education alone is effective in achieving clinically relevant reductions in ulcer and amputation incidence. To date, high quality evidence that more complex interventions including patient education can prevent diabetic foot ulceration is not available either. This, however, should be interpreted as lack of evidence rather than evidence of no effect. Future directions for research and practice may be to concentrate preventive effort on those patients who appear to be at highest risk of foot ulceration after careful screening and selection.

Abstract
OBJECTIVE To analyse the outcome of minor amputations (through, or distal to, the ankle joint) in patients with diabetes. METHOD All diabetic patients in a defined population undergoing one or more minor amputation between 1982 and 2006 were investigated according to a standardised protocol and were followed until final outcome (healing or death). A total of 410 consecutive amputations in 309 patients with a median age of 73 (32-93) years were identified. RESULTS In 94% of amputations, deep infection (39%) and/or gangrene (55%) was present. Severe peripheral vascular disease or critical limb ischaemia was present in 61% of amputations. 261/410 (64%) of the amputations healed at a level below the ankle joint; 69/410 (17%) healed after a re-amputation above the ankle joint; in 76/410 of amputations (19%), the patient died before healing could occur. In surviving patients, 79% of the amputations healed below the ankle. Median healing time for amputations that healed below the ankle was 26 (2-250) weeks; 21% of amputations required a re-amputation above the ankle. None of the analysed parameters excluded the possibility of healing below the ankle. CONCLUSION In this population-based survey, the goal of avoiding major amputation was achieved in almost two thirds of minor amputations, but at the price of long healing times. In almost all amputations, the patient had deep infection and/or gangrene. In spite of this, 64% of all amputations, and 79% of amputations in surviving patients, healed at a level below the ankle. This indicates that minor amputations in these patients are worthwhile. DECLARATION OF INTEREST None.

Abstract
BACKGROUND AND PURPOSE In the city of Trondheim, Norway, diabetic lower-limb amputations accounted for one-third of all lower-limb amputations (LLAs). In an attempt to reduce this rate, a diabetic foot team was established in 1996. We present the incidence of LLA in Trondheim as measured 10 years later. PATIENTS AND METHODS In 2004-07, we registered all LLAs performed in Trondheim and then compared the data with previously published data from 1994-1997. From 1996 through 2006, we registered the activity of the diabetic foot team and we also registered the number of vascular procedures performed on citizens of Trondheim from 1998 through 2006. RESULTS Comparing the two 3-year periods 1994-97 and 2004-07, we observed a decrease in all non-traumatic LLAs. The incidence of diabetic major LLAs per 10³ diabetics per year decreased from 4.0 to 2.4, and in patients with peripheral vascular disease we observed a decrease in LLAs from 18 to 12 per 10⁵ inhabitants per year. 5,915 consultations on diabetic subjects were conducted by the diabetic foot team during the period 1996-2006. From 1998 to 2006, the rate of vascular procedures decreased in the non-diabetic population, and was unchanged in diabetic subjects. INTERPRETATION In the population of Trondheim city there appears to have been a reduction in the rate of vascular obstructive lower-limb disease between the two 3-year periods 1994-97 and 2004-07. In our judgment, the decline in diabetic LLA also reflects better care of the diabetic foot.

Abstract
Background Diabetic foot complications are a leading cause of lower extremity amputation. With the increasing incidence of diabetes mellitus in the Arab world, specifically in the Kingdom of Saudi Arabia, the rate of amputation will rise significantly. A diabetic foot care program was implemented at King Abdulaziz Medical City in Riyadh, Saudi Arabia, in 2002. The program was directed at health care staff and patients to increase their awareness about diabetic foot care and prevention of complications. The purpose of this study was to perform a primary evaluation of the program’s impact on the rate of lower extremity amputation due to diabetic foot complications. Method This pilot study was the first analysis of the diabetic foot care program and examined two groups of participants for comparison, ie, a “before” group having had diabetic foot ulcers managed between 1983, when the hospital was first established, and 2002 when the program began and an “after group” having had foot ulcers managed between 2002 and 2004, in the program’s initial phase. A total of 41 charts were randomly chosen retrospectively. A data sheet containing age, gender, medical data, and the presentation, management, and outcome of diabetic foot cases was used for the analysis. Results The before group contained 20 patients (17 males) and the after group contained 21 patients (16 males). There was no difference between the two groups with regard to age and comorbidities. The rate of amputation was 70% in the before group and 61.9% in the after group. There was a decrease in the percentage of toe amputation in the after group and an increase in the percentage of below-knee amputation in the before group. However, these changes were not significant. Conclusion The program, although evaluated at an early stage, has increased the awareness of both patients and health care staff about the prevention and management of diabetic foot disease, and decreased the rate of lower extremity amputation. We believe that the statistical proof of its impact will be evident in the final evaluation.

Abstract
BACKGROUND Ulceration of the feet, which can result in loss of limbs and even death, is one of the major health problems for people with diabetes mellitus. OBJECTIVES To assess the effects of patient education on the prevention of foot ulcers in patients with diabetes mellitus. SEARCH STRATEGY Eligible studies were identified by searching the Cochrane Wounds Group Specialised Register (22 December 2009), the Cochrane Central Register of Controlled Trials (Cochrane Library 2009 Issue 4 ), Ovid MEDLINE (1950 to November Week 3 2009), Ovid MEDLINE In-Process & Other Non-Indexed Citations (Searched 22/12/09), Ovid EMBASE (1980 to 2009 Week 51) and EBSCO CINAHL (1982 to December 22 2009). SELECTION CRITERIA Prospective randomised controlled trials (RCTs) which evaluated educational programmes for preventing foot ulcers in people with diabetes mellitus. There was no restriction on language of the publications. DATA COLLECTION AND ANALYSIS Two review authors independently undertook data extraction and assessment of risk of bias. Primary end-points were foot ulceration or ulcer recurrence and amputation. MAIN RESULTS Eleven RCTs were included. Three studies described the effect of foot care education as part of general diabetes education compared with usual care. Two studies examined the effect of foot care education tailored to educational needs compared with no intervention. Finally, six studies described the effect of intensive compared with brief educational interventions. Pooling of outcome data was precluded by marked, mainly clinical, heterogeneity. Four RCTs assessed the effect of patient education on primary end-points: foot ulceration and amputations. One of these studies reported a statistically significant benefit of one hour group education after one year of follow-up in people with diabetes who were at high risk for foot ulceration; RR amputation 0.33 (95% CI 0.15 to 0.76); RR ulceration 0.31 (95% CI 0.14 to 0.66), however this study was at high risk of bias and may have overestimated the effect due to a unit of analysis error. One similar, but methodologically superior study did not confirm this finding; RR amputation 0.98 (95% CI 0.41 to 2.34); RR ulceration 1.00 (95% CI 0.70 to 1.44). The other two studies did not detect any effect of education on ulcer incidence or amputation but were underpowered. Patients' foot care knowledge was improved in the short term in five of eight RCTs in which this outcome was assessed, as was patients' self reported self care behaviour in the short term in seven of nine RCTs. The effects on callus, nail problems and fungal infections were described in five of the included studies, of which only two reported temporary improvements after an educational intervention.Only one of the included RCTs was considered to be at low risk of bias. AUTHORS' CONCLUSIONS Most of the RCTs included in this review are at high or unclear risk of bias. In some trials, foot care knowledge and self reported patient behaviour seem to be positively influenced by education in the short term. This, however, must be viewed with caution. The ultimate goal of educational interventions is preventing foot ulceration and amputation but only four RCTs reported these outcomes and only two reported sufficient data to examine this. Based on these two studies, we conclude that there is insufficient robust evidence that limited patient education alone is effective in achieving clinically relevant reductions in ulcer and amputation incidence.Future research should focus on evaluating the effect of more comprehensive and/or intensive prevention strategies which may also include patient education (complex interventions).

Abstract
Diabetic foot infections are the major cause of morbidity. Infection is the common sequel of diabetic foot ulceration that leads to delayed wound healing. These infections are difficult to control. If not addressed well in time, they may lead to amputation of foot. An attempt has been made to develop simple and effective treatment modality by using citric acid as a sole antimicrobial agent to control diabetic foot infections not responding to conventional treatment. Hundred and fifteen cases of diabetic foot ulcers of different Wagner grades infected with a variety of bacteria were investigated for culture and susceptibility, and susceptibility to citric acid. Citric acid gel was applied to ulcer to determine its efficacy in the management of diabetic foot ulcers with different Wagner grades. Citric acid gel was found effective in the control of foot infections; especially in Wagner grades I and II, the success rate was found to be more than 94%. In Wagner grade III also, it was found effective in complete healing of ulcers without deep osteomyelitis. Citric acid treatment is effective in the control of diabetic foot infections and in successful management of diabetic foot ulcers with Wagner grades I and II, and even with Wagner grade III, without deep osteomyelitis.

Abstract
Cutaneous anesthesia (EMLA_cream) of the forearm results in rapid improvement of hand sensibility, and here we applied this concept in the lower extremity. This double-blind study with 40 volunteers randomized to cutaneous application of anesthetic cream to the lower leg showed a significant improvement 2 h after treatment in touch thresholds in the EMLA group as compared with the placebo group. In 12 volunteers, fMRI examination was performed before and after treatment. Improvement was not associated with a visible cortical expansion of the cortical foot area. This novel finding may have considerable therapeutic potential in the treatment of foot sensibility disturbances in various neuropathies, such as diabetic neuropathy.

Abstract
OBJECTIVE The purpose of this study was to compare the incidence of vascular lower-limb amputation (LLA) in the diabetic and nondiabetic general population. RESEARCH DESIGN AND METHODS A population-based cohort study was conducted in a representative Swedish region. All vascular LLAs (at or proximal to the transmetatarsal level) performed from 1997 through 2006 were consecutively registered and classified into initial unilateral amputation, contralateral amputation, or reamputation. The incidence rates were estimated in the diabetic and nondiabetic general population aged > or =45 years. RESULTS During the 10-year period, LLA was performed on 62 women and 71 men with diabetes and on 79 women and 78 men without diabetes. The incidence of initial unilateral amputation per 100,000 person-years was 192 (95% CI 145-241) for diabetic women, 197 (152-244) for diabetic men, 22 (17-26) for nondiabetic women, and 24 (19-29) for nondiabetic men. The incidence increased from the age of 75 years. Of all amputations, 74% were transtibial. The incidences of contralateral amputation and of reamputation per 100 amputee-years in diabetic women amputees were 15 (7-27) and 16 (8-28), respectively; in diabetic men amputees 18 (10-29) and 21 (12-32); in nondiabetic women amputees 14 (7-24) and 18 (10-28); and in nondiabetic men amputees 13 (6-22) and 24 (15-35). CONCLUSIONS In the general population aged > or =45 years, the incidence of vascular LLA at or proximal to the transmetatarsal level is eight times higher in diabetic than in nondiabetic individuals. One in four amputees may require contralateral amputation and/or reamputation.

Abstract
UNLABELLED In 2005, it was estimated that more than 20 million people in the United States had diabetes. Approximately 30% of these people had undiagnosed cases. Increased risk for diabetes is primarily associated with age, ethnicity, family history of diabetes, smoking, obesity, and physical inactivity. Diabetes-related complications--including cardiovascular disease, kidney disease, neuropathy, blindness, and lower-extremity amputation--are a significant cause of increased morbidity and mortality among people with diabetes, and result in a heavy economic burden on the US health care system. With advances in treatment for diabetes and its associated complications, people with diabetes are living longer with their condition. This longer life span will contribute to further increases in the morbidity associated with diabetes, primarily in elderly people and in minority racial or ethnic groups. In 2050, the number of people in the United States with diagnosed diabetes is estimated to grow to 48.3 million. RESULTS from randomized controlled trials provide evidence that intensive lifestyle interventions can prevent or delay the onset of diabetes in high-risk individuals. In addition, adequate and sustained control of blood sugar levels, blood pressure, and blood lipid levels can prevent or delay the onset of diabetes-related complications in people with diabetes. Effective interventions, at both the individual and population levels, are desperately needed to slow the diabetes epidemic and reduce diabetes-related complications in the United States. This report describes the current diabetes epidemic and the health and economic impact of diabetes complications on individuals and on the health care system. The report also provides suggestions by which the epidemic can be curbed.

Abstract
BACKGROUND AND PURPOSE With an ageing population and an increasing incidence of diabetes, reduction of the number of diabetes-related amputations becomes increasingly difficult to achieve and maintain. There is controversy in this respect regarding the degree of success. We started a multidisciplinary treatment program for diabetic foot ulcers in 1982, and have now assessed incidence rates of amputations from 1982 through 2001. METHODS In a defined population, gradually increasing from 199,000 to 234,000, all diabetes-related amputations of the lower extremity from toe to hip were recorded from January 1, 1982 to December 31, 2001, using several sources of information. RESULTS The incidence of major amputations decreased by 0.57 from 16 (11-22) to 6.8 (6.1-7.5) per 100,000 inhabitants between the first and last 4-year period. The most substantial decrease was seen in patients aged 80 years and older. The fraction of amputations with a final level at or below the ankle (n = 240) increased from 0.23 in the first 4-year period to 0.31, 0.49, 0.47, and 0.49 in the following 4-year periods. The overall fraction of re-amputation was 0.34 in the first 4- year period and 0.27, 0.21, 0.32, and 0.21 in the following 4-year periods. The fraction of amputations in diabetic patients that were channeled through the footcare team prior to amputation increased from 0.51 in the first 4- year period to 0.83, 0.86, 0.90, and 0.90 in the following 4-year periods. INTERPRETATION Our findings indicate that a substantial decrease in the incidence of major lower extremity amputations in diabetic patients has been achieved and maintained.

Abstract
In order to direct scientific research, it is pivotal to know the extent of a clinical problem. Therefore, much effort has been undertaken to tally all diabetic foot problems around the world. Incidence and prevalence figures concerning both foot ulcerations and lower extremity amputations have been reported extensively worldwide. The figures presented are being compared with those from other countries, regions or clinics and those with the lowest numbers are deemed best practices.However, for these comparisons to be valid there are many possible pitfalls that are to be considered. A significant number of epidemiological and clinical considerations are to be dealt with and many of these are extremely important to realize when comparing ulceration or amputation rates. The influence of using a certain definition of nominators and denominators are explained. Also, the clinical setting in which the research has been performed is of importance. Many possible pitfalls are discussed in this presentation. Although there are limitations to this type of research, it may be the only way possible to go. In order to compare health strategies in certain areas of the world or to determine the importance of an intervention, incidence and prevalence figures certainly may prove a beneficial effect and therefore justify an intervention. Therefore, given the limitations epidemiological research concerning the prevalence and incidence of foot-related complications still forms the backbone of clinical research in the area of the diabetic foot.

Abstract
The incidence of re-amputation following lower extremity amputations (LEA) among the diabetic patients referred to the Artificial Limb and Appliance Centers (ALAC) in South Wales, UK, was investigated. Manual and electronic data-gathering systems were used to extract the medical records of 473 people with various causes of LEA referred to the ALAC in South Wales during 2001-2003. The data included demographic information, causes of amputation and occurrence of various levels of re-amputation. Two hundred and five subjects with diabetes underwent 316 amputations, 44 were foot amputations and 272 major amputations on the ipsilateral and contra-lateral sides. Of the diabetic patients, 45.9% with single LEA underwent re-amputations with 22% incidence of contra-lateral LEA within 2 years. In comparison, 15% underwent re-amputations in the non diabetic dysvascular patients. Ipsilateral re-amputations occurred much earlier (average 21 weeks) compared with the contra-lateral amputations which took an average of 82 weeks following the first amputation. Nearly half of the diabetic patients with single LEA referred for rehabilitation underwent re-amputations within 2 years; out of which 22% of the patients underwent contra-lateral LEA. Although the progression of level of amputations does not follow a particular pattern, re-amputation on the contra-lateral side occurred almost four times later than that on the ipsilateral side.

Abstract
Diabetes mellitus reached epidemic proportions in much of the less-developed world over a decade ago. In Africa, incidence and prevalence rates of diabetes are increasing and foot complications are rising in parallel. The predominant risk factor for foot complications is underlying peripheral neuropathy, although there is a body of evidence that confirm the increasing role of peripheral vascular disease. Gangrene and infections are two of the more serious sequelae of diabetic foot ulcer disease that cause long-standing disability, loss of income, amputation or death. Unfortunately, diabetes imposes a heavy burden on the health services in many African countries, where resources are already scarce or cut back. Reasons for poor outcomes of foot complications in various less-developed countries include the following: lack of awareness of foot care issues among patients and health care providers alike; very few professionals with an interest in the diabetic foot or trained to provide specialist treatment; non existent podiatry services; long distances for patients to travel to the clinic; delays among patients in seeking timely medical care, or among untrained health care providers in referring patients with serious complications for specialist opinion; lack of the concept of a team approach; absence of training programs for health care professionals; and finally lack of surveillance activities. There are ways of improving diabetic foot disease outcomes that do not require an exorbitant outlay of financial resources. These include implementation of sustainable training programmes for health care professionals, focusing on the management of the complicated diabetic foot and educational programmes that include dissemination of information to other health care professionals and patients; sustenance of working environments that inculcate commitment by individual physicians and nurses through self growth; rational optimal use of existing microbiology facilities and prescribing through epidemiologically directed empiricism, where appropriate; and using sentinel hospitals for surveillance activities. Allied with the golden rules of prevention (i.e. maintenance of glycaemic control to prevent peripheral neuropathy, regular feet inspection, making an effort not to walk barefooted or cut foot callosities with razors or knives at home and avoidance of delays in presenting to hospital at the earliest onset of a foot lesion), reductions in the occurrence of adverse events associated with the diabetic foot is feasible in less-developed settings.

Abstract
BACKGROUND To evaluate the economic aspects of diabetic foot care in a multidisciplinary setting. METHOD A review of the English language literature, published from 1966 to November 2005. RESULTS The results of available studies on the cost-of-illness of diabetic foot problems are difficult to compare. Nevertheless trends concerning excess of costs, protraction in time of costs, positive correlation to severity of ulcer and/or peripheral vascular disease, contribution of in-hospital stay and length of stay, and the patient's own contribution to total costs, are obvious. Only a few cost-effectiveness and cost-utility studies are available. Most use a Markov based model to predict outcome and show an acceptable result on long-term. CONCLUSIONS Diabetic foot problems are frequent and are associated with high costs. A multidisciplinary approach to diabetic foot problems has proved to be cost saving with regard to cost of treatment itself. Nevertheless, it remained unclear if these savings could offset the overall costs involved in implementing this kind of approach. The few studies that address this issue specifically all show an acceptable cost-effectiveness, but often the profit will be evident after some years only, because long-term costs are involved. Based on these data, policymakers should foresee sufficient reimbursement for preventive and early curative measures, and not only for 'salvage manoeuvres'.

Abstract
Understanding reasons for the neglect of foot screening during the annual review of people with diabetes enables the development of solutions for this omission. This study explores the reasons within the context of health care delivery systems in terms of the professional, social, political and economic aspects of this screening. Information was obtained through reviewing publications on diabetic foot and health care reform. The omission of annual foot examination for people with diabetes is attributed to the nature of diabetes-related foot problems, people with diabetes, health care professionals and the current structure of health care delivery systems. Increasing the adherence to foot screening for those with diabetes requires short- and long-term strategies. Short- and long-term strategies for reminding patients and staff about foot screening are suggested.

BACKGROUND Ulceration of the feet, which can result in loss of limbs and even death, is one of the major health problems for people with diabetes mellitus. OBJECTIVES To assess the effectiveness of patient education on the prevention of foot ulcers in patients with diabetes mellitus. SEARCH STRATEGY Eligible studies were identified by searching the Cochrane Wounds Group Specialised Register, (September 2004) and the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2004). SELECTION CRITERIA Prospective randomised controlled trials (RCTs) which evaluated educational programmes for the prevention of foot ulcers in people with diabetes mellitus. There was no restriction on language of the publications. DATA COLLECTION AND ANALYSIS Two reviewers undertook data extraction and assessment of study quality independently. MAIN RESULTS Nine RCTs were included. Four trials compared the effect of intensive with brief educational interventions; two of these reported clinical endpoints. One study involving high-risk patients reported a reduction in ulcer incidence (Peto OR: 0.28 (95% CI 0.13 - 0.59)) and amputation rate (Peto OR: 0.32 (95% CI 0.14 - 0.71)) after one year. The other RCT did not find an effect at seven years follow-up. Participants' foot care knowledge significantly improved with education in two trials. In one trial foot care knowledge improved significantly in the control group, in contrast to the intervention group. Non-calcaneal callus was significantly reduced by education in one trial. One RCT did not find that patient foot care education, as part of a general diabetes education program, reduced foot ulceration compared with usual care. Patient education as part of a complex intervention, targeted at both people with diabetes and doctors, reduced the number of serious foot lesions at one year in one RCT (OR: 0.41(95% CI 0.16 -1.00)) and improved foot care behaviour. Evidence from three RCTs comparing the effect of patient-tailored education in addition to usual care was conflicting.The methodological quality of the nine included RCTs was poor. The internal validity score (range 0 - 10) of individual RCTs ranged from 2 to 5. AUTHORS' CONCLUSIONS RCTs evaluating education for people with diabetes, aimed at preventing diabetic foot ulceration, are mostly of poor methodological quality. Weak evidence suggests that patient education may reduce foot ulceration and amputations, especially in high-risk patients. Foot care knowledge and behaviour of patients seem positively influenced by patient education in the short term. Because of conflicting results and the methodological shortcomings more RCTs are needed.

Abstract
OBJECTIVE Lower-extremity amputation is a common complication among patients with diabetes throughout the world. However, few data exist on the actual impact of the recent moves to improve the management of diabetic foot ulcers to reduce the incidence of lower-extremity amputations. The aim was to determine the incidence of lower-extremity amputations among diabetic patients from 1991 to 2000 in The Netherlands. RESEARCH DESIGN AND METHODS A secondary database containing information regarding all hospital admissions in which a lower-extremity amputation occurred for the years 1991-2000 was obtained from the Dutch National Medical Register. Because a patient-unique identifier was included, multiple amputations and hospitalizations for a single individual could be identified. Furthermore, age- and sex-specific diabetes prevalence rates were calculated using a 3-year average for every year, calculating the total diabetic population in the Netherlands at risk for every year. RESULTS In 1991, a total of 1,687 patients with diabetes had been admitted 1,865 times for 2,409 amputations. In 2000, a total of 1,673 patients with diabetes were admitted 1,932 times for 2,448 amputations. The overall incidence rates of the number of patients who underwent lower-extremity amputation decreased over the years from 55.0 to 36.3 per 10,000 patients with diabetes (P < 0.05). Both in men (71.8 vs. 46.1, P < 0.05) and women (45.0 vs. 28.0, P < 0.05) with diabetes, a significant decrease could be observed. Mean duration of hospitalization decreased from 45.0 days (SD 44.4) in 1991 to 36.2 days (SD 38.4) in 2000; decreases were observed for both men and women. CONCLUSIONS Over the years observed in this study, the incidence rates of diabetes-related lower-extremity amputation in The Netherlands was found to decrease in both men (36%) and women (38%) with diabetes. Furthermore, the duration of hospitalization decreased over time.

Abstract
Diabetic foot, an important cause of morbidity and mortality, is an important economic problem in all countries. We examined the duration of diabetes, ratio of hospitalization, and the amputation rates of our diabetic foot patients between 1996 and 2002 and compared the results with those obtained between 1985 and 1995. Medical reports of 117 patients with diabetic foot referred to Gazi University Medical Faculty between 1996 and 2002 were retrospectively analyzed. The mean age was 61.09+/-10.87 years and mean duration of diabetes was 16.14+/-9.44 years. Sixty-one patients were hospitalized and 56 patients were followed in our outpatient clinic. The mean duration of hospitalization was 45.00+/-18.74 (20-74) days in amputees and 28.95+/-11.61 (10-47) days in the nonamputees (P=.023). The mean age and duration of diabetes were significantly higher in amputees in the present group than that in the previous group. The amputation rate was significantly lower in the group studied between 1996 and 2002 compared to the group followed between 1985 and 1995 (9.4% vs. 21%, respectively, P<.001). Appropriate diabetes education and systematic follow-up in an outpatient clinic may delay preventable diabetic foot lesions and reduce the amputation rate.

Abstract
Diabetic foot ulcers pose a great burden on both the patient and the health care system. A multifactorial approach is necessary in diagnosing and treating these patients, with the input of many different specialists. These different view points and approaches were the basis for the International Consensus on the Diabetic Foot, resulting in a worldwide network of professionals involved in the management of diabetic patients with foot problems. Moreover, several consensus texts were produced and the project resulted in many (local) national initiatives. These activities, which are a continuous process and which are embedded in the International Diabetes Federation, are described in the article.

OBJECTIVE Ulceration of the feet, which can result in loss of limbs and death, is a major health problem for people with diabetes mellitus. The objective of this review is to assess the effectiveness of patient education to prevent diabetic foot ulcers. RESEARCH DESIGN AND METHODS We conducted a systematic review of randomized controlled trials (RCTs) that evaluated educational programmes for the prevention of foot ulcers in people with diabetes mellitus. We used standard search methods of the Cochrane "Wounds Groups". Two reviewers working independently extracted data and assessed study quality. RESULTS The methodologic quality of the 8 included RCTs was poor. The internal validity score (range 0-10) of individual RCTs ranged from 2 to 4. Four trials compared the effect of intensive with brief educational interventions; 2 of these reported clinical endpoints. One study involving high-risk patients reported a reduction in ulcer incidence (OR 0.28, 95% confidence interval [CI] 0.13-0.59) and amputation rate (OR 0.32, 95% CI 0.14-0.71) after 1 year. The other RCT did not find an effect after 7 years of follow-up. Two trials showed that participants' foot care knowledge significantly improved with education. In one trial, foot care knowledge was significantly worse at 6 months, although foot care behavior improved significantly. One RCT, that compared patient foot care education as part of a general diabetes education program to usual care, showed no reduction in the risk of foot ulceration. In one RCT, patient education as part of a complex intervention targeted at both people with diabetes and doctors reduced the prevalence of serious foot lesions at 1 year (OR 0.41, 95% CI 0.16-1.00) and improved foot care behavior. Evidence from two RCTs comparing the effect of patient-tailored education in addition to usual care was conflicting. SUMMARY Evidence, limited by poor methodologic quality and conflicting results, suggests that patient education may have positive but short-lived effects on foot care knowledge and behavior of patients and may reduce foot ulceration and amputations, especially in high-risk patients. High-quality randomized controlled trials are needed to establish the efficacy of patient education to prevent diabetic foot ulcerations.

Abstract
There is a current lack of evidence for most of the treatments that are applied to those patients who have diabetic foot problems. This paper reviews existing evidence and national and international consensus documents. The diabetic foot is an enormous public health problem and it is important that it receives rapid and effective management.

Abstract
BACKGROUND The cause of diabetic foot ulcers is multifactorial, e.g., neuropathy and angiopathy, leading to functional disturbances in the macrocirculation and skin microcirculation. Adequate tissue oxygen tension is an essential factor in infection control and wound healing. Hyperbaric oxygen (HBO) therapy, daily sessions of oxygen breathing at 2.5-bar increased pressure in a hyperbaric chamber, has beneficial actions on wound healing including antimicrobial action, prevention of edema and stimulation of fibroblasts. The aim of the present study was to investigate the long-term effect of HBO in treatment of diabetic foot ulcers. METHODS Thirty-eight diabetic patients (30 males) with chronic foot ulcers were investigated in a prospective study. The mean age was 60+/-13 years and the mean diabetes duration 27+/-14 years. All patients were evaluated with measurements of transcutaneous oxygen tension (tcPO(2)), peripheral blood pressure, and HbA(1c). All patients had a basal tcPO(2) value lower than 40 mmHg, which increased to >/=100 mmHg, or at least three times the basic value, during inhalation of pure oxygen. Seventeen patients underwent 40-60 sessions of HBO therapy, while 21 patients were treated conventionally. The follow-up time was 3 years. RESULTS 76% of the patients treated with HBO (Group A) had healed with intact skin at a follow-up time of 3 years. The corresponding value for patients treated conventionally (Group B) was 48%. Seven patients (33%) in Group B compared to two patients (12%) in Group A went to amputation. Peripheral blood pressure, HbA(1c), diabetes duration, and basal values of tcPO(2) were similar in both groups. CONCLUSIONS Adjunctive HBO therapy can be valuable for treating selected cases of hypoxic diabetic foot ulcers. It seems to accelerate the rate of healing, reduce the need for amputation, and increase the number of wounds that are completely healed on long-term follow-up. Additional studies are needed to further define the role of HBO, as part of a multidisciplinary program, to preserve a functional extremity, and reduce the short- and long-term costs of amputation and disability.
