Background: Falls in older people are a major public health problem, and there is increasing evidence that foot problems and inappropriate footwear increase the risk of falls. Several multidisciplinary prevention clinics have been established to address the problem of falls; however, the role of podiatry in these clinics has not been clearly defined. The aims of this study were to determine the level of podiatric involvement in multidisciplinary falls clinics in Australia and to describe the assessments undertaken and interventions provided by podiatrists in these settings.
Methods: A database of falls clinics was developed through consultation with departments of health in each state and territory. Clinic managers were contacted and surveyed as to whether the clinic incorporated podiatry services. If so, the podiatrists were contacted and asked to complete a brief questionnaire regarding their level of involvement and the assessment procedures and interventions offered.
Results: Of the 36 clinics contacted, 25 completed the survey. Only four of these clinics reported direct podiatric involvement. Despite the limited involvement of podiatry in these clinics, all of the clinic managers stated that they considered podiatry to have an important role to play in falls prevention. Podiatry service provision in falls clinics varied considerably in relation to eligibility criteria, assessments undertaken, and interventions provided.
Conclusions: Despite the recognition that foot problems and inappropriate footwear are risk factors for falls, podiatry currently has a relatively minor and poorly defined role in multidisciplinary falls-prevention clinics in Australia. (J Am Podiatr Med Assoc 97(5): 377–384, 2007)
Background: Diabetic foot infections (DFIs) can lead to limb loss and mortality. To improve patient care at a safety-net teaching hospital, we created a multidisciplinary limb salvage service (LSS).
Methods: We recruited a cohort prospectively and compared it to a historical control group. Adults admitted to the newly established LSS for DFI during a 6-month period from 2016 to 2017 were included prospectively. Patients admitted to the LSS had routine endocrine and infectious diseases consultations according to a standardized protocol. A retrospective analysis of patients admitted to the acute care surgical service for DFI before creation of the LSS during an 8-month period from 2014 to 2015 was performed.
Results: A total of 250 patients were divided into two groups: the pre-LSS (n = 92) and the LSS (n = 158) groups. There were no significant differences in baseline characteristics. Although all patients were ultimately diagnosed with diabetes, more patients in the LSS group had hypertension (71% versus 56%; P = .01) and a prior diagnosis of diabetes mellitus (92% versus 63%; P < .001) compared to the pre-LSS group. Significantly, with the LSS, fewer patients underwent a below-the-knee amputation (3.6% versus 13%; P = .001). There was no difference in the length of hospital stay or 30-day readmission rate between the groups. Further broken down into Hispanic versus non-Hispanic, we noted that Hispanics had significantly lower rates of below-the-knee amputations (3.6% versus 13.0%; P = .02) in the LSS cohort.
Conclusions: The initiation of a multidisciplinary LSS decreased the below-the-knee amputation rate in patients with DFIs. Length of stay was not increased, nor was the 30-day readmission rate affected. These results suggest that a robust multidisciplinary LSS dedicated to the management of DFIs is both feasible and effective, even in safety-net hospitals.
Background
Diabetes-related lower limb amputations (LLAs) are a major complication that can be reduced by employing multidisciplinary center frameworks such as the Toe and Flow model (TFM). In this study, we investigate the LLAs reduction efficacy of the TFM compared to the standard of care (SOC) in the Canadian health-care system.
Methods
We retrospectively reviewed the anonymized diabetes-related LLA reports (2007-2017) in Calgary and Edmonton metropolitan health zones in Alberta, Canada. Both zones have the same provincial health-care coverage and similar demographics; however, Calgary operates based on the TFM while Edmonton with the provincial SOC. LLAs were divided into minor and major amputation cohorts and evaluated using the chi-square test, linear regression. A lower major LLAs rate was denoted as a sign for higher efficacy of the system.
Results
Although LLAs numbers remained relatively comparable (Calgary: 2238 and Edmonton: 2410), the Calgary zone had both significantly lower major (45%) and higher minor (42%) amputation incidence rates compared to the Edmonton zone. The increasing trend in minor LLAs and decreasing major LLAs in the Calgary zone were negatively and significantly correlated (r = -0.730, p = 0.011), with no significant correlation in the Edmonton zone.
Conclusions
Calgary's decreasing diabetes-related major LLAs and negative correlation in the minor-major LLAs rates compared to its sister zone Edmonton, provides support for the positive impact of the TFM. This investigation includes support for a modernization of the diabetes-related limb preservation practice in Canada by implementing TFMs across the country to combat major LLAs.
Abstract
Background: The purpose of this retrospective audit was to compare patient based clinical outcomes to amputation healing outcomes twelve months after a minor foot amputation in people with diabetes.
Methods: Hospital admission and community outpatient data were extracted for all minor foot amputations in people with diabetes in 2017 in the Central Coast Local Health District.
Results: A total 85 minor foot amputations involving 74 people were identified. At the twelve-month follow-up 74% (n=56) of the minor foot amputations healed, 63% (n=41) of the participants achieved a good clinical outcome (healed, no more proximal amputations, or death within the 12 month follow up period), and the mortality rate was 18%. Poor clinical outcomes were associated with those aged greater than 60 (RR 5.75, 95% CI: 0.85 to 38.7, p=0.013), those undergoing a further surgical debridement procedure during their hospital stay (RR 2.42, 95% CI: 1.3 to 4.4, p=0.005) and those who did not attend CCLHD Podiatry clinics post-amputation (RR 2.3, 95% CI: 1.2 to 4.1, p=0.010).
Conclusions: To improve patient based clinical outcomes post-minor foot amputation, targeted follow-up in a high-risk foot clinic, and tailored discharge treatment plans for people aged over 60 or those undergoing a debridement procedure may be considered.
Background:
One relatively universal functional goal after major lower-limb amputation is ambulation in a prosthesis. This retrospective, observational investigation sought to 1) determine what percentage of patients successfully walked in a prosthesis within 1 year after major limb amputation and 2) assess which patient factors might be associated with ambulation at an urban US tertiary-care hospital.
Methods:
A retrospective medical record review was performed to identify consecutive patients undergoing major lower-limb amputation.
Results:
The overall rate of ambulation in a prosthesis was 29.94% (50.0% of those with unilateral below-the-knee amputation [BKA] and 20.0% of those with unilateral above-the-knee amputation [AKA]). In 24.81% of patients with unilateral BKA or AKA, a secondary surgical procedure of the amputation site was required. In those with unilateral BKA or AKA, statistically significant factors associated with ambulation included male sex (odds ratio [OR] = 2.50) and at least 6 months of outpatient follow-up (OR = 8.10), survival for at least 1 postoperative year (OR = 8.98), ambulatory preamputation (OR = 14.40), returned home after the amputation (OR = 6.12), and healing of the amputation primarily without a secondary surgical procedure (OR = 3.62). Those who had a history of dementia (OR = 0.00), a history of peripheral arterial disease (OR = 0.35), and a preamputation history of ipsilateral limb revascularization (OR = 0.14) were less likely to walk. We also observed that patients with a history of outpatient evaluation by a podiatric physician before major amputation were 2.63 times as likely to undergo BKA as opposed to AKA and were 2.90 times as likely to walk after these procedures.
Conclusions:
These results add to the body of knowledge regarding outcomes after major amputation and could be useful in the education and consent of patients faced with major amputation.
Both vascular surgeons and podiatric physicians care for patients with diabetic foot ulcerations (DFUs), one of today's most challenging health-care populations in the United States. The prevalence of DFUs has steadily increased, along with the rising costs associated with care. Because of the numerous comorbidities affecting these patients, it is necessary to take a multidisciplinary approach in the management of these patients. Such efforts, primarily led by podiatric physicians and vascular surgeons, have been shown to effectively decrease major limb loss. Establishing an interprofessional partnership between vascular surgery and podiatric medicine can lead to an improvement in the delivery of care and outcomes of this vulnerable patient population.
History of the Team Approach to Amputation Prevention
Pioneers and Milestones
This historical perspective highlights some of the pioneers, milestones, teams, and system changes that have had a major impact on management of the diabetic foot during the past 100 years. In 1934, American diabetologist Elliott P. Joslin noted that mortality from diabetic coma had fallen from 60% to 5% after the introduction of insulin, yet deaths from diabetic gangrene of the lower extremity had risen significantly. He believed that diabetic gangrene was preventable. His remedy was a team approach that included foot care, diet, exercise, prompt treatment of foot infections, and specialized surgical care.
The history of the team approach to management of the diabetic foot chronicles the rise of a new health profession—podiatric medicine and surgery—and emergence of the specialty of vascular surgery. The partnership among the diabetologist, vascular surgeon, and podiatric surgeon is a natural one. The complementary skills and knowledge of each can improve limb salvage and functional outcomes. Comprehensive multidisciplinary foot-care programs have been shown to increase quality of care and reduce amputation rates by 36% to 86%. Development of distal revascularization techniques to restore pulsatile blood flow to the foot has also been a major advancement.
Patients with diabetic foot complications are among the most complex and vulnerable of all patient populations. Specialized diabetic foot clinics of the 21st century should be multidisciplinary and equipped to coordinate diagnosis, off-loading, and preventive care; to perform revascularization procedures; to aggressively treat infections; and to manage medical comorbidities.

Background: Comparing the dynamic pedobarographic patterns of individuals is common practice in basic and applied research. However, this process is often time-consuming and complex, and commercially available software often lacks powerful visualization and interpretation tools.
Methods: We propose a simple method for displaying pixel-level pedobarographic deviations over time relative to a so-called reference pedobarographic pattern. This novel method contains four distinct automated preprocessing stages: 1) normalization of pedobarographic fields (for foot length and width), 2) temporal normalization, 3) a pixel-level z-score–based calculation, and 4) color coding of the normalized pedobarographic fields. Group and patient-level comparisons were illustrated using an experimental data set including diabetic and nondiabetic patients.
Results: The automated procedure was found to be robust and quantified distinct temporal deviations in pedobarographic fields.
Conclusions: The advantages of the novel method cover several domains, including visualization, interpretation, and education.
Decreasing Amputation Rates in Patients with Diabetes Mellitus
An Outcome Study
The lower-extremity amputation rate in people with diabetes mellitus is high, and the wound failure rate at the time of amputation is as high as 28%. Even with successful healing of the primary amputation site, amputation of part of the contralateral limb occurs in 50% of patients within 2 to 5 years. The purpose of this study was to provide valid outcome data before (control period) and 18 months after (test period) implementation of a multidisciplinary team approach using verified methods to improve the institutional care of wounds. Retrospective medical chart review was performed for 118 control patients and 116 test patients. The amputation rate was significantly decreased during the test period, and the amputations that were required were at a significantly more distal level. No above-the-knee amputations were required in 45 patients during the test period, compared with 14 of 76 patients during the control period. These outcome data suggest that unified care is an effective approach for the patient with diabetic foot problems. (J Am Podiatr Med Assoc 92(8): 425-428, 2002)
