[PMID: 39197376 DOI: 10.1016/j.artmed.2024.102966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 01/20/2024] [Accepted: 08/19/2024] [Indexed: 09/01/2024]
Abstract
This comprehensive systematic review critically analyzes the current progress and challenges in automating transtibial prosthesis alignment. The manual identification of alignment changes in prostheses has been found to lack reliability, necessitating the development of automated processes. Through a rigorous systematic search across major electronic databases, this review includes the highly relevant studies out of an initial pool of 2111 records. The findings highlight the urgent need for automated alignment systems in individuals with transtibial amputation. The selected studies represent cutting-edge research, employing diverse approaches such as advanced machine learning algorithms and innovative alignment tools, to automate the detection and adjustment of prosthesis alignment. Collectively, this review emphasizes the immense potential of automated transtibial prosthesis alignment systems to enhance alignment accuracy and significantly reduce human error. Furthermore, it identifies important limitations in the reviewed studies, serving as a catalyst for future research to address these gaps and explore alternative machine learning algorithms. The insights derived from this systematic review provide valuable guidance for researchers, clinicians, and developers aiming to propel the field of automated transtibial prosthesis alignment forward.

Abstract
BACKGROUND lower limb amputation (LLA) is a growing problem in the population with and without diabetes mellitus. Monitoring the incidence rates of LLA is important for health care planning and has implications for the future problems of medical and social care. OBJECTIVE This study aimed to determine the trends in incidence rates of LLA due to nondiabetic peripheral artery disease in Novokuznetsk, Western Siberia, Russia. STUDY DESIGN An observational study. METHODS Data on all transtibial and transfemoral amputations performed in inpatient facilities in Novokuznetsk from 1996 to 2019 were derived from the regional Register of patients with limb amputations. The rates were calculated per 100,000 population. RESULTS A total of 2448 persons with amputations due to nondiabetic peripheral artery disease were included in this study (3191 amputations). The overall incidence rate of LLA in Novokuznetsk increased from 14.6 in 1996 to 30.4 in 2019. The proportion of persons older than 60 years increased from 15.5% in 1996 to 20.3% in 2019. CONCLUSION The expected aging of the population and increasing incidence of LLA are relevant issues in Russia. These findings can contribute to improving healthcare services and the development of prevention programs to reverse the alarming trend.

Abstract
BACKGROUND Dietary intake is a recognised contributor to healing in diabetes-related foot ulceration (DFU). However, it is currently unknown how individuals with DFU perceive their diet, and what is deemed an acceptable dietary intervention. Therefore, the aims of this study were to explore perceptions of diet quality, previous dietary advice, and dietary interventions in individuals with DFU, and secondly to determine acceptable dietary interventions in individuals with DFU to assist with wound healing. METHODS A qualitative study using reflexive thematic analysis was undertaken. Individuals with active or recent history of DFU were recruited from a high-risk foot service. Semi-structured interviews were undertaken. RESULTS Nineteen participants were included with three themes identified: A complex relationship with food, perceptions of food, diet and dietitians, and self-management. Dietary misconceptions were common. Self-perceived diet quality varied, with most unaware of how diet could impact wound healing. Many expressed barriers relating to food agency (purchasing, preparing, and accessing food). Participants expressed a strong preference for personalised, face-to-face dietary advice and nutritional supplementation. CONCLUSIONS There is a need for personalised dietary re-education and assistance with food agency in this cohort to overcome commonly held misconceptions of diet and improve dietary intake to facilitate wound healing.

Abstract
BACKGROUND Diabetes-related foot infections cause substantial morbidity and mortality, both globally and in Australia. There is a need for up-to-date evidence-based guidelines to ensure optimal management of patients with diabetes-related foot infections. We aimed to identify and adapt high quality international guidelines to the Australian context to become the new Australian evidence-based guideline for people with a diabetes-related foot infection. METHODS Following Australian National Health and Medical Research Council (NHMRC) procedures we identified the 2019 International Working Group on the Diabetic Foot (IWGDF) guidelines as suitable for adaptation to the Australian context. Guidelines were screened, assessed and judged by an expert panel for the Australian context using the guideline adaptation frameworks ADAPTE and Grading of Recommendations Assessment, Development and Evaluation (GRADE). Judgements led to recommendations being adopted, adapted or excluded, with additional consideration regarding their implementation, monitoring and future research for the Australian context. Clinical pathways were then developed to assist implementation. RESULTS Of 36 original diabetes-related foot infection IWGDF sub-recommendations, 31 were adopted, four were adapted and one was excluded. Adaption was primarily undertaken due to differences or clarification of the sub-recommendations' intended population. One sub-recommendation was excluded due to substantial differences in judgements between the panel and IWGDF and unacceptable heterogeneity of the target population. Therefore, we developed 35 evidence-based sub-recommendations for the Australian context that should guide best practice diagnosis and management of people with diabetes-related foot infection in Australia. Additionally, we incorporated these sub-recommendations into two clinical pathways to assist Australian health professionals to implement these evidence-based sub-recommendations into clinical practice. The six guidelines and the full protocol can be found at: https://www.diabetesfeetaustralia.org/new-guidelines/ . CONCLUSIONS A new national guideline for the diagnosis and management of people with diabetes-related foot infections were successfully developed for the Australian context. In combination with simplified clinical pathway tools they provide an evidence-based framework to ensure best management of individuals with diabetes-related foot infections across Australia and highlight considerations for implementation and monitoring.

Factors influencing lower extremity amputation outcomes in people with active foot ulceration in regional Australia: A retrospective cohort study. Wound Repair Regen 2021; 30:24-33.

Abstract
Australia has the second highest rate of non-traumatic lower extremity amputation (LEA) globally. Australia's large geographical size is one of the biggest challenges facing limb preservation services and may be contributing to LEA. The aim of this study was to determine what factors contribute to the likelihood of LEA in people with active foot ulceration in regional Australia. This retrospective cohort study audited patients with active foot ulceration in a multidisciplinary high risk foot service (HRFS) in regional Australia. Neurological, vascular and wound characteristics were systematically extracted, along with demographic information. Participants were followed for at least 12 months until healing or LEA occurred. Correlations between LEA and clinical and demographic characteristics were assessed using the Pearson's product moment correlation coefficient and chi squared test for independence. Significant variables (p < 0.05) were included in the model. Direct logistic regression assessed the independent contribution of significantly correlated variables on the likelihood of LEA. Of note, 1876 records were hand screened with 476 participants (25%) meeting the inclusion criteria. Geographical distance from the HRFS, toe systolic pressure (TSP), diabetes and infection were all significantly correlated with LEA and included in the logistic regression model. TSP decrease of 1 mmHg (OR 1.02, 95% CI 1.01-1.03), increased geographical distance (1 km) from HRFS (OR 1.006, 95% CI 1.001-1.01) infection (OR 2.08, 95% CI 1.06-4.07) and presence of diabetes (OR 3.77, 95% CI 1.12-12.65) were all significantly associated with increased likelihood of LEA. HRFS should account for the disparity in outcomes between patients living in close proximity to their service, compared to those in rural areas. Optimal management of diabetes, vascular perfusion and control of infection may also contribute to preventing LEA in people with active foot ulceration.

Transtibial Osseointegration for Patients with Peripheral Vascular Disease: A Case Series of 6 Patients with Minimum 3-Year Follow-up. JB JS Open Access 2021; 6:JBJSOA-D-20-00113.

Abstract
The management of peripheral vascular disease (PVD) can require amputation. Osseointegration surgery is an emerging rehabilitation strategy for amputees. In this study, we report on 6 patients who had PVD requiring transtibial amputation (PVD-TTA) and either simultaneous or subsequent osseointegration (PVD-TTOI). Methods Six patients (aged 36 to 84 years) with transtibial amputation and preexisting PVD underwent osseointegration between 2014 and 2016 and were followed for 3 to 5 years. Pre- and postoperative clinical and functional outcomes (pain, prosthesis wear time, mobility, walking ability, and quality of life) and adverse events (infection, fracture, implant failure, revision surgery, additional amputation, and death) were prospectively recorded. Results All patients' mobility improved following osseointegration. Three patients initially had required the use of a wheelchair, precluding baseline walking tests; the other 3 were classified as K level 1 or 2, with mean baseline Timed Up and Go (TUG) test = 14.0 ± 2.2 s and 6-Minute Walk Test (6MWT) = 262 ± 75 m. At the time of the latest follow-up, all patients were K level 2 or 3; mean TUG = 12.7 ± 7.2 s and 6MWT = 353 ± 148 m. Four patients wore their prosthesis ≥16 hours daily. Three patients had superficial soft-tissue infections. One other patient experienced recurrent infections 2.8 years after osseointegration requiring debridements and transfemoral amputation; the patient died 2 days following surgery from myocardial infarction caused by coronary atherosclerosis. Conclusions All 6 patients who underwent PVD-TTOI in this case series survived through 2 years. Patients who initially had used a wheelchair achieved and maintained independent, unaided ambulation until PVD-related impairments in the contralateral leg occurred in 1 patient. Patients previously using a traditional socket prosthesis reported improvement in mobility and quality of life. One patient's death underscores the importance of careful patient selection. However, marked improvement in the other 5 patients suggests cautious optimism that PVD-TTA is not an absolute osseointegration contraindication. Conscientious further investigation seems appropriate. Level of Evidence Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
AIMS Peripheral artery disease (PAD) revascularization can be performed by either endovascular or open surgical approach. Despite increasing use of endovascular revascularization, it is still uncertain which strategy yields better long-term outcomes. METHODS AND RESULTS This retrospective cohort study evaluated patients hospitalized with PAD in Australia and New Zealand who underwent either endovascular or surgical revascularization between 2008 and 2015, and compared procedures using a propensity score-matched analysis. Hybrid interventions were excluded. The primary endpoint was mortality or major adverse limb events (MALE), defined as a composite endpoint of acute limb ischaemia, urgent surgical or endovascular reintervention, or major amputation, up to 8 years post-hospitalization using time-to-event analyses 75 189 patients fulfilled eligibility (15 239 surgery and 59 950 endovascular), from whom 14 339 matched pairs (mean ± SD age 71 ± 12 years, 73% male) with good covariate balance were identified. Endovascular revascularization was associated with an increase in combined MALE or mortality [hazard ratio (HR) 1.13, 95% confidence interval (CI): 1.09-1.17, P < 0.001]. There was a similar risk of MALE (HR 1.04, 95% CI: 0.99-1.10, P = 0.15), and all-cause urgent rehospitalizations (HR 1.01, 95% CI: 0.98-1.04, P = 0.57), but higher mortality (HR 1.16, 95% CI: 1.11-1.21, P < 0.001) when endovascular repair was compared to surgery. In subgroup analysis, these findings were consistent for both claudication and chronic limb-threatening ischaemia presentations. CONCLUSION Although the long-term risk of MALE was comparable for both approaches, enduring advantages of surgical revascularization included lower long-term mortality. This is at odds with some prior PAD studies and highlights contention in this space.

Abstract
PURPOSE OF STUDY To investigate toe systolic blood pressure and/or toe-brachial pressure index in predicting healing post minor diabetic foot amputations. KEY METHODS A systematic search of EMBASE and PubMed (including Medline and The Cochrane Library) was conducted from database inception to 9 March 2020. Two authors independently reviewed and selected relevant studies. Quality was assessed with a modified Critical Appraisal Skill Programme checklist. MAIN RESULTS Ten studies met the inclusion criteria. Nine studies investigating toe systolic blood pressure reported healing occurred at mean toe systolic blood pressure values ⩾30 mmHg, ranging between 30 and 83.6 mmHg. The meta-analysis (four studies) found toe systolic blood pressure <30 mmHg had 2.09 times the relative risk of non-healing post amputation, compared to toe systolic blood pressure ⩾30 mmHg (relative risk = 2.09, 95% confidence interval: 1.37-3.20, p = 0.001). Two studies investigating toe-brachial pressure index report successful healing where toe-brachial pressure index >0.2, with one study reporting a higher value of 0.8. MAIN CONCLUSIONS Successful post-amputation healing outcomes were reported at mean toe systolic blood pressure ⩾30 mmHg, and the results varied considerably between the studies. Further research should identify whether variables, including amputation level, method of wound closure and length of post-operative follow-up periods, affect the values of toe systolic blood pressure and toe-brachial pressure index observed in this review.

Abstract
BACKGROUND An increasing prevalence of diabetes mellitus has led to a high risk of diabetic foot infections (DFI) and associated morbidity. However, little is known about the relationship between DFI and mortality. AIM To investigate the risk of mortality and associated factors in patients with DFI in an Australian context. METHODS A prospective cohort study of inpatients with DFI between May 2012 and October 2016 was done at Royal Darwin Hospital, a tertiary referral hospital for the Top End of the Northern Territory. Primary outcome was 1-year mortality with Cox regression analysis undertaken to assess risk factors for mortality. RESULTS Four hundred and thirteen consecutive adult diabetic patients with 737 admissions were referred to the High-Risk Foot Service for DFI. Cumulative risk of mortality at 1 year was 8.9% (95% confidence interval (CI) 6.4-12.2). On univariable analysis, mortality was associated with older age (hazard ratio (HR) per year increase 1.08, 95% CI 1.06-1.11, P = 0.001), haemodialysis (HR 3.64, 1.74-7.62, P < 0.001), isolation of Pseudomonas aeruginosa (HR 2.32, 1.05-5.12, P = 0.04) and ischaemic heart disease (HR 2.05, 1.04-4.07, P = 0.04), while indigenous status (HR 0.48, 0.25-0.95, P = 0.04) and HbA1c > 7% (HR 0.45, 0.20-0.99, P < 0.05) were protective. After adjusting for confounders, independent risk factors for mortality were haemodialysis (adjusted HR 5.76, 95% CI 2.28-14.59, P < 0.001) and older age (adjusted HR 1.09, 1.06-1.13, P < 0.001). Patients on haemodialysis had a cumulative risk of mortality of 24.5% (95% CI 14.0-40.8) at 1 year. CONCLUSION There is a high risk of mortality associated with DFI, substantially increased in patients undergoing haemodialysis, highlighting the importance of early and dedicated interventions targeted at this high-risk group.

Abstract
Although more and more data on lower limb amputations are becoming available by leveraging the widening access to health care administrative databases, the applicability of these data for public health decisions is still limited. Problems can be traced back to methodological issues, how data are generated and to conceptual issues, namely, how data are interpreted in a multidimensional environment. The present review summarised all of the steps from converting the claims data of administrative databases into the analytical data and reviewed the wide array of sources of potential biases in the analysis of such data. The origins of uncertainty of administrative data analysis include uncontrolled confounding due to a lack of clinical data, the left- and right-censored nature of data collection, the non-standardized diagnosis/procedure-based data extraction methods (i.e., numerator/denominator problems) and additional methodological problems associated with temporal and spatial analyses. The existence of these methodological challenges in the administrative data-based analysis should not deter the analysts from using these data as a powerful tool in the armamentarium of clinical research. However, it must be done with caution and a thorough understanding and respect of the methodological limitations. In addition to this requirement, there is a profound need for pursuing further research on methodology and widening the search for other indicators (structural, process or outcome) that allow a deeper insight how the quality of vascular care may be assessed. Effective research using administrative data is based on strong collaboration in three domains, namely expertise in claims data handling and processing, the clinical field, and statistical analysis. The final interpretations of results and the countermeasures on the level of vascular care ought to be grounded on the integrity of research, open discussions and institutionalized mechanisms of science arbitration and honest brokering.

Abstract
BACKGROUND: Ambulation with a prosthesis is the ultimate goal of rehabilitation for a person with a major lower limb amputation. Due to challenges with prosthetic service delivery in rural settings, many patients with amputations are not benefitting from prosthetic interventions. Inaccessibility to prosthetic services results in worse functional outcomes and quality of life. Learning from the experiences of current prosthetic users in this setting can assist to improve prosthetic service delivery. OBJECTIVES: To explore the experiences of lower limb prosthetic users and to understand the importance of a lower limb prosthesis to a prosthetic user in a rural area of South Africa. STUDY DESIGN: A generic qualitative approach and an explorative design were utilised in this study. METHODS: A semi-structured interview guide was used to collect data from nine prosthetic users in a rural area in the Mpumalanga province of South Africa. Interviews were audio-recorded, transcribed verbatim and analysed thematically. Demographic details and information related to acute in-patient rehabilitation were analysed descriptively. RESULTS: All participants were independent in activities of daily living with their prosthesis and participated actively in their community. Participants reported that their prosthesis was essential to their functioning. High travel cost was highlighted as a barrier to the maintenance of their prosthesis. Patients were dissatisfied with being unemployed. CONCLUSION: Prosthetic intervention positively influences function, independence and community participation. Challenges relating to the accessibility, cost and maintenance of prosthetics should be a priority to ensure continued functional independence for prosthetic users. CLINICAL RELEVANCE Understanding the importance of a prosthesis to a prosthetic user validates prosthetic intervention for persons living with an amputation in a rural setting and is vital in establishing and remodelling effective systems for prosthetic service delivery.

Abstract
Purpose: What are the characteristics of people with lower limb amputation at admission to, and discharge from, subacute rehabilitation? Have these characteristics changed over time?Methods: A total of 425 lower limb amputation inpatient rehabilitation admissions (335 individuals) from 2005 to 2011 were examined. Admission characteristics, including aetiology, gender, age, amputation level, cognition (Mini-Mental State Examination (MMSE)), indoor mobility aid, motor function (Functional Independence Measure motor subscale) and number and type of comorbidities, and discharge characteristics, including prosthetic prescription, motor function, discharge mobility aid, and destination were compared by admission date and year.Results: Proportion of people with lower limb amputation with nonvascular aetiology increased over time (2004, 15% to 2011, 24%) (ß = -181.836, p < 0.001). Admission cognition increased over time (ß = 9.296, p < 0.001). Motor function worsened over time; median admission (IQR) Functional Independence Measure motor 70 (59-77) in 2005 to 67 (51.5-73.25) in 2011 (ß = -1.937, p < 0.001) and discharge from 81 in 2005 to 79 in 2011 (ß = -1.267, p < 0.001). Prosthetic prescription rates were highest in 2005 (68%) decreasing to 47% in 2010 (ß = -200.473, p < 0.001).Conclusions: Total numbers of people with lower limb amputation did not change over the seven-year study period. Changes were observed in aetiology, cognition and motor function. Prosthetic prescription rates decreased over time.Implications for rehabilitationRehabilitation should account for the changing characteristics of people with lower limb amputation.Motor function should be addressed as part of rehabilitation to optimise the patient's ability to return home and to the community.Prescription rates for lower limb prostheses reduced across time, indicating more specific selection processes and refined clinical decision making; this decision is best informed by a multi-disciplinary approach.

Abstract
BACKGROUND After amputation patients are more likely to injure their residual limb. An injury of a previously amputated limb, especially if the residuum is not anatomically normal, poses a dilemma for management. Case Description and Methods: This case report discusses a femoral fracture sustained proximal to a through-knee amputation. Findings and outcomes: The fracture was at the site of a malunited fracture. A shortening osteotomy with bone graft was undertaken to improve alignment and prosthetic fit and remove poor-quality bone. This was stabilised using an intramedullary nail, supplemented with an anti-rotation plate. This fracture went on to uneventful union, and the patient was able to comfortably use a prosthesis with increased functionality compared with prior to the recent injury. DISCUSSION This management enabled quick healing of the fracture without the need to resort to a more proximal amputation. CONCLUSION In these unusual cases, careful planning is necessary to ensure all aspects of the problem is dealt with. Each case should be treated on its own merits. Clinical relevance This case demonstrates the difficulty in care of complex limb trauma and offers a solution for management of similar cases. Excellent results are possible when all surgical options are considered.

Abstract
BACKGROUND Osseointegration is an alternative treatment for amputees who are unable to wear or have difficulty wearing a socket prosthesis. Although the majority of limb amputations are due to vascular disease, such amputations have been perceived as a contraindication to osseointegration surgery. We report the outcomes of osseointegrated reconstruction in a series of 5 patients with limb amputation due to peripheral vascular disease. METHODS Five patients with transtibial amputation and a history of peripheral vascular disease who received an osseointegration implant from 2014 to 2015 were followed for 12 months. Clinical and functional outcomes were assessed, including pain, the amount of time the patient wore the prosthesis, mobility, walking ability, and quality of life. Adverse events, including infection, fracture, implant failure, revision surgery, additional amputation, and death, were monitored and recorded. RESULTS Five transtibial amputees (56 to 84 years of age) followed for 1 year after osseointegration surgery were included in this case series. The mobility of all patients was improved at the time of follow-up. Three patients were wheelchair-bound prior to the surgery but all 5 were able to walk and perform daily activities at the time of follow-up. Four of the 5 patients were pain-free at 12 months postoperatively, and all 5 were using the osseointegrated prosthesis. Two patients had a single episode of superficial soft-tissue infection. CONCLUSIONS An osseointegrated implant may be considered a feasible alternative to the conventional socket prosthesis for patients with peripheral vascular disease.

Abstract
OBJECTIVE The cost of treating diabetes-related disease in New Zealand is increasing and is expected to reach New Zealand dollars (NZD) 1.8 billion in 2021. The financial burden attached to the treatment of diabetic foot wounds is difficult to quantify and reported costs of treatment vary greatly in the literature. As of yet, no study has captured the true total cost of treating a diabetic foot wound. In this study, we investigate the total minimum cost of treating a diabetic foot ulcer at a tertiary institution. METHODS A retrospective audit of hospital and interhospital records was performed to identify adult patients with diabetes who were treated operatively for a diabetic foot wound by the department of vascular surgery at Auckland Hospital between January 2009 and June 2014. Costs from the patients' admissions and outpatient clinics from their first meeting to the achievement of a final outcome were tallied to calculate the total cost of healing the wound. The hospital's expenses were calculated using a fully absorbed activity-based costing methodology and correlated with a variety of demographic and clinical factors extracted from patients' electronic records using a general linear mixed model. RESULTS We identified 225 patients accounting for 265 wound episodes, 700 inpatient admissions, 815 outpatient consultations, 367 surgical procedures, and 248 endovascular procedures. The total minimum cost to the Auckland city hospital was NZD 10,217,115 (NZD 9,886,963 inpatient costs; NZD 330,152 outpatient costs). The median cost per wound episode was NZD 29,537 (NZD 28,491 inpatient costs; NZD 834 outpatient cost). Wound healing was achieved in 70% of wound episodes (average length of healing, 9 months); 19% of wounds had not healed before the patient's death. Of every 3.5 wound episodes, one required a major amputation. Wound treatment modality, particularly surgical management, was the strongest predictor of high resource utilization. Wounds treated with endovascular intervention and no surgical intervention cost less. Surgical management (indiscriminate of type) was associated with faster wound healing than wounds managed endovascularly (median duration, 140 vs 224 days). Clinical risk factors including smoking, ischemic heart disease, hypercholesterolemia, hypertension, and chronic kidney disease did not affect treatment cost significantly. CONCLUSIONS We estimate the minimum median cost incurred by our department of vascular surgery in treating a diabetic foot wound to be NZD 30,000 and identify wound treatment modality to be a significant determinant of cost. While readily acknowledging our study's inherent limitations, we believe it provides a real-world representation of the minimum total cost involved in treating diabetic foot lesions in a tertiary center. Given the increasing rate of diabetes, we believe this high cost reinforces the need for the establishment of a multidisciplinary diabetic foot team in our region.

Abstract
In Australia, little is known about how the incidence rate (IR) of lower limb amputation (LLA) varies across the country. While studies in other economically developed countries have shown considerable geographic variation in the IR-LLA, mostly these have not considered whether the effect of common risk factors are the same across regions. Mapping variation of the IR-LLA, and the effect of common risk factors, is an important first step to focus research into areas of greatest need and support the development of regional specific hypotheses for in-depth examination. The aim of this study was to describe the geographic variation in the IR-LLA across Australia and understand whether the effect of common risk factors was the same across regions. Using hospital episode data from the Australian National Hospital Morbidity database and Australian Bureau of Statistics, the all-cause crude and age-standardised IR-LLA in males and females were calculated for the nation and each state and territory. Generalised Linear Models were developed to understand which factors influenced geographic variation in the crude IR-LLA. While the crude and age-standardised IR-LLA in males and females were similar in most states and territories, they were higher in the Northern Territory. The effect of older age, being male and the presence of type 2 diabetes was associated with an increase of IR-LLA in most states and territories. In the Northern Territory, the younger age at amputation confounded the effect of sex and type 2 diabetes. There are likely to be many factors not included in this investigation, such as Indigenous status, that may explain part of the variation in the IR-LLA not captured in our models. Further research is needed to identify regional- and population- specific factors that could be modified to reduce the IR-LLA in all states and territories of Australia.

Abstract
The aims of this study were to investigate the point prevalence, and associated independent factors, for foot disease (ulcers, infections and ischaemia) in a representative hospitalised population. We included 733 (83%) of 883 eligible adult inpatients across five representative Australian hospitals on one day. We collected an extensive range of self-reported characteristics from participants. We examined all participants to clinically diagnose foot disease (ulcers, infections and ischaemia) and amputation procedures. Overall, 72 participants (9·8%) [95% confidence interval (CI):7·2-11·3%] had foot disease. Foot ulcers, in 49 participants (6·7%), were independently associated with peripheral neuropathy, peripheral arterial disease, previous foot ulcers, trauma and past surgeon treatment (P < 0·05). Foot infections, in 24 (3·3%), were independently associated with previous foot ulcers, trauma and past surgeon treatment (P < 0·01). Ischaemia, in 33 (4·5%), was independently associated with older age, smokers and past surgeon treatment (P < 0·01). Amputation procedures, in 14 (1·9%), were independently associated with foot infections (P < 0·01). We found that one in every ten inpatients had foot disease, and less than half of those had diabetes. After adjusting for diabetes, factors linked with foot disease were similar to those identified in diabetes-related literature. The overall inpatient foot disease burden is similar in size to well-known medical conditions and should receive similar attention.

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

Abstract
OBJECTIVE To systematically review studies reporting the prevalence in general adult inpatient populations of foot disease disorders (foot wounds, foot infections, collective 'foot disease') and risk factors (peripheral arterial disease (PAD), peripheral neuropathy (PN), foot deformity). METHODS A systematic review of studies published between 1980 and 2013 was undertaken using electronic databases (MEDLINE, EMBASE and CINAHL). Keywords and synonyms relating to prevalence, inpatients, foot disease disorders and risk factors were used. Studies reporting foot disease or risk factor prevalence data in general inpatient populations were included. Included study's reference lists and citations were searched and experts consulted to identify additional relevant studies. 2 authors, blinded to each other, assessed the methodological quality of included studies. Applicable data were extracted by 1 author and checked by a second author. Prevalence proportions and SEs were calculated for all included studies. Pooled prevalence estimates were calculated using random-effects models where 3 eligible studies were available. RESULTS Of the 4972 studies initially identified, 78 studies reporting 84 different cohorts (total 60 231 517 participants) were included. Foot disease prevalence included: foot wounds 0.01-13.5% (70 cohorts), foot infections 0.05-6.4% (7 cohorts), collective foot disease 0.2-11.9% (12 cohorts). Risk factor prevalence included: PAD 0.01-36.0% (10 cohorts), PN 0.003-2.8% (6 cohorts), foot deformity was not reported. Pooled prevalence estimates were only able to be calculated for pressure ulcer-related foot wounds 4.6% (95% CI 3.7% to 5.4%)), diabetes-related foot wounds 2.4% (1.5% to 3.4%), diabetes-related foot infections 3.4% (0.2% to 6.5%), diabetes-related foot disease 4.7% (0.3% to 9.2%). Heterogeneity was high in all pooled estimates (I(2)=94.2-97.8%, p<0.001). CONCLUSIONS This review found high heterogeneity, yet suggests foot disease was present in 1 in every 20 inpatients and a major risk factor in 1 in 3 inpatients. These findings are likely an underestimate and more robust studies are required to provide more precise estimates.

[PMID: 26098890 PMCID: PMC4476617 DOI: 10.1371/journal.pone.0130609] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2014] [Accepted: 05/21/2015] [Indexed: 12/30/2022] Open
Abstract
Objective To determine trends in the incidence of foot-related hospitalisation and amputation amongst persons with diabetes in Queensland (Australia) between 2005 and 2010 that coincided with changes in state-wide ambulatory diabetic foot-related complication management. Methods All data from cases admitted for the principal reason of diabetes foot-related hospitalisation or amputation in Queensland from 2005–2010 were obtained from the Queensland Hospital Admitted Patient Data Collection dataset. Incidence rates for foot-related hospitalisation (admissions, bed days used) and amputation (total, minor, major) cases amongst persons with diabetes were calculated per 1,000 person-years with diabetes (diabetes population) and per 100,000 person-years (general population). Age-sex standardised incidence and age-sex adjusted Poisson regression models were also calculated for the general population. Results There were 4,443 amputations, 24,917 hospital admissions and 260,085 bed days used for diabetes foot-related complications in Queensland. Incidence per 1,000 person-years with diabetes decreased from 2005 to 2010: 43.0% for hospital admissions (36.6 to 20.9), 40.1% bed days (391 to 234), 40.0% total amputations (6.47 to 3.88), 45.0% major amputations (2.18 to 1.20), 37.5% minor amputations (4.29 to 2.68) (p < 0.01 respectively). Age-sex standardised incidence per 100,000 person-years in the general population also decreased from 2005 to 2010: 23.3% hospital admissions (105.1 to 80.6), 19.5% bed days (1,122 to 903), 19.3% total amputations (18.57 to 14.99), 26.4% major amputations (6.26 to 4.61), 15.7% minor amputations (12.32 to 10.38) (p < 0.01 respectively). The age-sex adjusted incidence rates per calendar year decreased in the general population (rate ratio (95% CI)); hospital admissions 0.949 (0.942–0.956), bed days 0.964 (0.962–0.966), total amputations 0.962 (0.946–0.979), major amputations 0.945 (0.917–0.974), minor amputations 0.970 (0.950–0.991) (p < 0.05 respectively). Conclusions There were significant reductions in the incidence of foot-related hospitalisation and amputation amongst persons with diabetes in the population of Queensland over a recent six-year period.

Abstract
Background Diabetic foot complications are the leading cause of lower extremity amputation and diabetes-related hospitalisation in Australia. Studies demonstrate significant reductions in amputations and hospitalisation when health professionals implement best practice management. Whilst other nations have surveyed health professionals on specific diabetic foot management, to the best of the authors’ knowledge this appears not to have occurred in Australia. The primary aim of this study was to examine Australian podiatrists’ diabetic foot management compared with best practice recommendations by the Australian National Health Medical Research Council. Methods A 36-item Australian Diabetic Foot Management survey, employing seven-point Likert scales (0 = Never; 7 = Always) to measure multiple aspects of best practice diabetic foot management was developed. The survey was briefly tested for face and content validity. The survey was electronically distributed to Australian podiatrists via professional associations. Demographics including sex, years treating patients with diabetes, employment-sector and patient numbers were also collected. Chi-squared and Mann Whitney U tests were used to test differences between sub-groups. Results Three hundred and eleven podiatrists responded; 222 (71%) were female, 158 (51%) from the public sector and 11–15 years median experience. Participants reported treating a median of 21–30 diabetes patients each week, including 1–5 with foot ulcers. Overall, participants registered median scores of at least “very often” (>6) in their use of most items covering best practice diabetic foot management. Notable exceptions were: “never” (1 (1 – 3)) using total contact casting, “sometimes” (4 (2 – 5)) performing an ankle brachial index, “sometimes” (4 (1 – 6)) using University of Texas Wound Classification System, and “sometimes” (4 (3 – 6) referring to specialist multi-disciplinary foot teams. Public sector podiatrists reported higher use or access on all those items compared to private sector podiatrists (p < 0.01). Conclusions This study provides the first baseline information on Australian podiatrists’ adherence to best practice diabetic foot guidelines. It appears podiatrists manage large caseloads of people with diabetes and are generally implementing best practice guidelines recommendations with some notable exceptions. Further studies are required to identify barriers to implementing these recommendations to ensure all Australians with diabetes have access to best practice care to prevent amputations.

AUST HEALTH REV 2015; 39:76-84.

Abstract
Objective To examine personal and social demographics, and rehabilitation discharge outcomes of dysvascular and non-vascular lower limb amputees. Methods In total, 425 lower limb amputation inpatient rehabilitation admissions (335 individuals) from 2005 to 2011 were examined. Admission and discharge descriptive statistics (frequency, percentages) were calculated and compared by aetiology. Results Participants were male (74%), aged 65 years (s.d. 14), born in Australia (72%), had predominantly dysvascular aetiology (80%) and a median length of stay 48 days (interquartile range (IQR): 25–76). Following amputation, 56% received prostheses for mobility, 21% (n = 89) changed residence and 28% (n = 116) required community services. Dysvascular amputees were older (mean 67 years, s.d. 12 vs 54 years, s.d. 16; P < 0.001) and recorded lower functional independence measure – motor scores at admission (z = 3.61, P < 0.001) and discharge (z = 4.52, P < 0.001). More non-vascular amputees worked before amputation (43% vs 11%; P < 0.001), were prescribed a prosthesis by discharge (73% vs 52%; P < 0.001) and had a shorter length of stay (7 days, 95% confidence interval: –3 to 17), although this was not statistically significant. Conclusions Differences exist in social and demographic outcomes between dysvascular and non-vascular lower limb amputees. What is known about the topic? Lower limb amputation occurs due to various aetiologies. What does this paper add? Lower limb amputee rehabilitation over 7 years was investigated, comprising 425 admissions, 80% due to dysvascular aetiology. Personal and social demographics, and discharge outcomes are compared by aetiology. What are the implications for practitioners? Demographic and discharge outcome differences exist between dysvascular and non-vascular lower limb amputees. Twenty-one percent were required to change residence and 28% required additional social supports. Discharge planning should begin as soon as possible to limit time spent waiting for new accommodation or major modifications for current homes. Lower limb amputees are not homogeneous, so care should be taken if extrapolating from combined amputee aetiologies or from one aetiology to another.

Abstract
Objetivo Analisar a rede de atenção à pessoa amputada na perspectiva dos profissionais de saúde inseridos nos serviços de alta complexidade. Métodos Pesquisa qualitativa com coleta de dados mediante entrevista semi-estruturada com profissionais de diferentes áreas de atuação envolvidos no cuidado à pessoa amputada. Resultados Observou-se que uma parte dos profissionais entrevistados conhece e atua em uma perspectiva de encaminhamento para reabilitação, enquanto outros desconhecem o fluxo de encaminhamento bem como a rede de atenção que ampara estes usuários. Conclusão Os dados evidenciaram como grande fortaleza no contexto da reabilitação o trabalho multiprofissional e inter-instituicional ocorrido em alguns espaços. Como principal fragilidade aponta a falta de conhecimento dos profissionais sobre a alta complexidade das redes de atenção à saúde, assim como a maneira como a reabilitação é vista, não sendo inserida em um contexto de cuidado desde que exista a possibilidade ou ocorrência da amputação.

J Foot Ankle Res 2014; 7:41.

Abstract
BACKGROUND Australian subacute inpatient rehabilitation facilities face significant challenges from the ageing population and the increasing burden of chronic disease. Foot disease complications are a negative consequence of many chronic diseases. With the rapid expansion of subacute rehabilitation inpatient services, it seems imperative to investigate the prevalence of foot disease and foot disease risk factors in this population. The primary aim of this cross-sectional study was to determine the prevalence of active foot disease and foot disease risk factors in a subacute inpatient rehabilitation facility. METHODS Eligible participants were all adults admitted at least overnight into a large Australian subacute inpatient rehabilitation facility over two different four week periods. Consenting participants underwent a short non-invasive foot examination by a podiatrist utilising the validated Queensland Health High Risk Foot Form to collect data on age, sex, medical co-morbidity history, foot disease risk factor history and clinically diagnosed foot disease complications and foot disease risk factors. Descriptive statistics were used to determine the prevalence of clinically diagnosed foot disease complications, foot disease risk factors and groups of foot disease risk factors. Logistic regression analyses were used to investigate any associations between defined explanatory variables and appropriate foot disease outcome variables. RESULTS Overall, 85 (88%) of 97 people admitted to the facility during the study periods consented; mean age 80 (±9) years and 71% were female. The prevalence (95% confidence interval) of participants with active foot disease was 11.8% (6.3 - 20.5), 32.9% (23.9 - 43.5) had multiple foot disease risk factors, and overall, 56.5% (45.9 - 66.5) had at least one foot disease risk factor. A self-reported history of peripheral neuropathy diagnosis was independently associated with having multiple foot disease risk factors (OR 13.504, p = 0.001). CONCLUSION This study highlights the potential significance of the burden of foot disease in subacute inpatient rehabilitation facilities. One in eight subacute inpatients were admitted with active foot disease and one in two with at least one foot disease risk factor in this study. It is recommended that further multi-site studies and management guidelines are required to address the foot disease burden in subacute inpatient rehabilitation facilities.

Abstract
BACKGROUND Contemporary literature reports that the incidence of lower limb amputation has declined in many countries. This impression may be misleading given that many publications only describe the incidence of lower limb amputations above the ankle and fail to include lower limb amputations below the ankle. OBJECTIVES To describe trends in the incidence of different levels of lower limb amputation in Australian hospitals over a 10-year period. STUDY DESIGN Descriptive. METHOD Data describing the age-standardised incidence of lower limb amputation were calculated from the Australian National Hospital Morbidity database and analysed for trends over a 10-year period. RESULTS The age-standardised incidence of lower limb amputation remained unchanged over time (p = 0.786). A significant increase in the incidence of partial foot amputations (p = 0.001) and a decline in the incidence of transfemoral (p = 0.00) and transtibial amputations (p = 0.00) were observed. There are now three lower limb amputations below the ankle for every lower limb amputation above the ankle. CONCLUSION While the age-standardised incidence of all lower limb amputation has not changed, a shift in the proportion of lower limb amputations above the ankle and lower limb amputations below the ankle may be the result of improved management of precursor disease that makes partial foot amputation a more commonly utilised alternative to lower limb amputations above the ankle. Clinical relevance This article highlights that although the incidence of lower limb amputation has remained steady, the proportion of amputations above the ankle and below the ankle has changed dramatically over the last decade. This has implications for how we judge the success of efforts to reduce the incidence of lower limb amputation and the services required to meet the increasing proportion of persons with amputation below the ankle.

Abstract
BACKGROUND Great emphasis is placed on the skeletal medio-lateral to maintain the normal adduction of the remnant femur and to ensure coronal plane stability in an ischial containment socket. Given the invasiveness of the skeletal medio-lateral measurement, an alternative approach using prediction based on non-invasive measures would be welcomed. OBJECTIVES Determine the accuracy with which the skeletal medio-lateral dimension could be predicted using sex, stature, anterior-posterior dimension and iliofemoral angle. STUDY DESIGN Cross-sectional. METHOD Anthropometric measurements on 77 persons were recorded and used as input data into a standard multiple regression. RESULTS The regression model explained 59% of the variance in skeletal medio-lateral (r(2) = 0.59) that was statistically significant (F(4,72) = 25.37, p = 0.000). Only sex contributed significantly to the prediction of skeletal medio-lateral (β = 0.67, t = 6.15, p = 0.00). The degree of error associated with the regression model (sum of squared errors = 0.009) indicated that the actual skeletal medio-lateral could be predicted within ±18 mm in 95% of the cases. CONCLUSION The regression model is not sufficiently accurate to predict skeletal medio-lateral for clinical purposes. Accuracy of the prediction could be improved with more accurate input data from computed tomography scans and use of other independent variables that explain the unique variance not already described by the participants' sex. Clinical relevance This pilot study demonstrates potential for the skeletal medio-lateral to be predicted using non-invasive anthropometric measurements. Given this proof of concept, future investigators should use more accurate input data from computed tomography scans and identify alternative independent variables that explain the variance in the skeletal medio-lateral not attributable to sex.

J Foot Ankle Res 2014; 7:7. [PMID: 24468080 PMCID: PMC3906769 DOI: 10.1186/1757-1146-7-7] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2013] [Accepted: 01/22/2014] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Foot disease complications, such as foot ulcers and infection, contribute to considerable morbidity and mortality. These complications are typically precipitated by "high-risk factors", such as peripheral neuropathy and peripheral arterial disease. High-risk factors are more prevalent in specific "at risk" populations such as diabetes, kidney disease and cardiovascular disease. To the best of the authors' knowledge a tool capturing multiple high-risk factors and foot disease complications in multiple at risk populations has yet to be tested. This study aimed to develop and test the validity and reliability of a Queensland High Risk Foot Form (QHRFF) tool. METHODS The study was conducted in two phases. Phase one developed a QHRFF using an existing diabetes foot disease tool, literature searches, stakeholder groups and expert panel. Phase two tested the QHRFF for validity and reliability. Four clinicians, representing different levels of expertise, were recruited to test validity and reliability. Three cohorts of patients were recruited; one tested criterion measure reliability (n = 32), another tested criterion validity and inter-rater reliability (n = 43), and another tested intra-rater reliability (n = 19). Validity was determined using sensitivity, specificity and positive predictive values (PPV). Reliability was determined using Kappa, weighted Kappa and intra-class correlation (ICC) statistics. RESULTS A QHRFF tool containing 46 items across seven domains was developed. Criterion measure reliability of at least moderate categories of agreement (Kappa > 0.4; ICC > 0.75) was seen in 91% (29 of 32) tested items. Criterion validity of at least moderate categories (PPV > 0.7) was seen in 83% (60 of 72) tested items. Inter- and intra-rater reliability of at least moderate categories (Kappa > 0.4; ICC > 0.75) was seen in 88% (84 of 96) and 87% (20 of 23) tested items respectively. CONCLUSIONS The QHRFF had acceptable validity and reliability across the majority of items; particularly items identifying relevant co-morbidities, high-risk factors and foot disease complications. Recommendations have been made to improve or remove identified weaker items for future QHRFF versions. Overall, the QHRFF possesses suitable practicality, validity and reliability to assess and capture relevant foot disease items across multiple at risk populations.

Abstract
AIMS To compare direct medical costs 1 year before up to 3 years after first major lower extremity amputation (LEA) between patients with and without diabetes. METHODS We used health insurance claims data and included patients with a first major LEA between 2005 and 2009. Costs for hospitalization, rehabilitation, outpatient care, outpatient drug prescriptions, non-physician services, durable medical equipment and long-term care were assessed. We estimated cost ratios (CR) for diabetes status using generalized linear models adjusted for age, sex, amputation level, care dependency as well as observation time and mortality within the corresponding period and costs before LEA. RESULTS We included 444 patients with first major LEA (58.3% had diabetes), 71.8% were male and the average age was 69.1 years. Total mean costs for 1 year before LEA were higher in patients with diabetes (24,504 vs. 18,961 Euros), which was also confirmed by the multivariate analysis (CR: 1.27; 95% CI: 1.06-1.52). Costs up to 24 weeks after LEA were virtually the same in both groups (36,686 vs. 35,858 Euros), but thereafter differences increase again with higher costs for diabetics. Costs for 3 years after LEA were 115,676 vs. 92,862 Euros, respectively (CR: 1.26; 95% CI: 1.12-1.42). Hospitalizations accounted for more than 50% of total costs irrespective of diabetes status and period. CONCLUSIONS Costs up to 24 weeks after first major LEA are mainly driven by the amputation itself irrespective of diabetes. Thereafter, costs for diabetic patients were higher again, which underlines the importance of studying long-term costs.

Abstract
BACKGROUND Limb loss occurs as a result of different causes and has been increasing in many countries. This study determines the demography of amputees in one of the relatively large cities of Iran. METHODS This retrospective study was undertaken on all of the amputees between 2003 and 2011. Patients' demographics including age, sex, the limb that had undergone amputation, etiology of limb loss and side and level of amputation were recorded. Also, the level of amputation was recorded as minor (below wrist or ankle) or major (above wrist or ankle). RESULTS In total, 624 patients were enrolled in the study. The number of amputees was from 53 to 118/year. Of the patients, 508 were male (81.4 %) and 118 were female (18.6 %). The men with amputation were younger on average than women; 61.9 % of the amputations (386) were major and 38.1 % were minor (238). Overall, the most common cause of amputation was trauma and the most common level was transmetatarsal. The most common level for major amputations was below knee. CONCLUSION In contrast to similar studies in developed countries, trauma was found to be the major cause of all types of amputations and in all age groups, which emphasizes the need for preventive measures in the country.

Abstract
Diabetes is one of the greatest public health challenges to face Australia. It is already Australia's leading cause of kidney failure, blindness (in those under 60 years) and lower limb amputation, and causes significant cardiovascular disease. Australia's diabetes amputation rate is one of the worst in the developed world, and appears to have significantly increased in the last decade, whereas some other diabetes complication rates appear to have decreased. This paper aims to compare the national burden of disease for the four major diabetes-related complications and the availability of government funding to combat these complications, in order to determine where diabetes foot disease ranks in Australia. Our review of relevant national literature indicates foot disease ranks second overall in burden of disease and last in evidenced-based government funding to combat these diabetes complications. This suggests public funding to address foot disease in Australia is disproportionately low when compared to funding dedicated to other diabetes complications. There is ample evidence that appropriate government funding of evidence-based care improves all diabetes complication outcomes and reduces overall costs. Numerous diverse Australian peak bodies have now recommended similar diabetes foot evidence-based strategies that have reduced diabetes amputation rates and associated costs in other developed nations. It would seem intuitive that "it's time" to fund these evidence-based strategies for diabetes foot disease in Australia as well.
