Nature and extent of outpatient podiatry service utilisation in people with diabetes undergoing minor foot amputations : a retrospective clinical audit

Background: People with diabetes are at high risk of foot complications that can lead to lower extremity amputations. National standards suggest that early assessment and management by a podiatry led multidisciplinary high-risk foot clinic (HRFC) helps to reduce complications. This review is a retrospective audit of the Central Coast Local Health District (CCLHD) podiatry department service utilisation in people with diabetes who had undergone a minor foot amputation. Methods: All people with diabetes who had minor foot amputations in the calendar year 2017 in the CCLHD in New South Wales were identified. Podiatry occasions of service from all podiatry service clinics (e.g. general, orthoses, wound, HRFC) and hospital stays for 12 months prior to, and 12 months, post the minor foot amputation were extracted. Results: Data on 74 people with diabetes who underwent 85 minor foot amputations were collected. In the 12-month period leading up to their minor foot amputation less than half, 42% (n=31), of the patients had attended any of the available podiatry service clinics within the CCLHD system. Post-amputation and discharge from hospital there was an overall rise of 26% in numbers attending all CCLHD podiatry- led clinics bringing the total to 68% (51). However, attendance at the HRFC rose by only 2% from 16% (n=12) to 18% n= (13). Conclusion: This study shows that there was underutilisation of Podiatry Services in the CCLHD in 2017 with some participants not meeting national treatment guidelines for foot health services. Revision of current referral pathways both prior to, during and following hospitalisation and expanding the multidisciplinary HRFC to accommodate the population by providing more accessible locations has since been undertaken to increase service access. Further provision of education to those highlighted to be at high risk has also been implemented

Accurate noninvasive arterial assessment of the wounded lower limb: a clinical challenge for wound practitioners

Arterial investigations are an essential part of lower extremity wound assessment. The results of these investigations assist the wound clinician to determine the etiology of the wound, predict healing capacity, and inform further management. There are a number of noninvasive testing methods available to practitioners, all with varying levels of reliability and accuracy. Clinical wound assessment guidelines give varied recommendations when it comes to lower limb vascular assessment in the presence of a wound. This leaves clinicians with little guidance on how to choose the most appropriate test, and uncertainty remains about which tests provide the most accurate information in different patient-specific contexts. Conditions such as advanced age, diabetes, and renal disease are known to affect the accuracy of some commonly used lower limb arterial assessment methods, and alternate testing methods should be considered in these cases. This seminal review discusses the reliability and accuracy of lower limb vascular assessment methods used to guide lower limb arterial assessment in the presence of wounds

Relationship between lower limb vascular characteristics, peripheral arterial disease and gait in rheumatoid arthritis

Objectives: Rheumatoid arthritis (RA) is associated with higher risk of atherosclerotic vascular disease, including peripheral arterial disease (PAD). The aim of this study was to measure lower limb vascular characteristics (indicative of PAD), using non-invasive chairside testing methods, in people with RA compared to matched controls, and to determine the association between vascular characteristics and gait velocity as a measure of functional capacity in people with RA. Methods: This was a cross-sectional pilot study which measured lower limb vascular characteristics (bilateral continuous wave Doppler, toe brachial index [TBI] and ankle brachial index [ABI]) and gait velocity (6-m walk test) in people with RA and controls. Differences in vascular characteristics between groups were determined using linear regression models, and associations between vascular characteristics and gait were determined using logistic regression models. Results: Seventy-two participants were included: 34 participants with RA mean disease duration 26.2 (SD 12.1) and 38 age- and sex-matched controls. The control group contained 30 females (79%), and the RA group had 28 females (82%). There were no significant differences between the RA and control groups for lower limb vascular characteristics. People with RA walked significantly slower compared to controls (1.10 m/s vs 0.91 m/s, P <.001). People with RA who had abnormal TBI, or abnormal qualitative Doppler walked significantly slower compared to those with normal TBI (0.86 m/s vs 0.95 m/s, P =.043 and 0.81 m/s, vs 0.93 m/s, P =.028). There was no significant association between ABI and gait velocity. Conclusion: This study did not identify different lower limb vascular characteristics in people with RA compared to matched controls. However, in people with RA, abnormal Doppler and TBI results are associated with slower walking velocity
