Effect of a multidisciplinary team approach on the management of diabetic foot ulcers on the Central Coast: A review of the Gosford Hospital High-Risk Foot Clinic.

This retrospective cohort study aims to assess whether the implementation of a multidisciplinary approach in the Gosford Hospital High-Risk Foot Clinic improved outcomes of diabetic foot ulcers. Ulceration is a common foot complication of diabetes mellitus and greatly increases patient morbidity and mortality. Patients who attended at least one appointment at the Gosford Hospital High-Risk Foot Clinic in 2017 or 2019 were identified through the Gosford Hospital Podiatry department's records. The 2017 and 2019 cohorts were compared on measures of ulcer healing, incidence of amputation, incidence of vascular intervention and surgical debridement, percentage of patients admitted to hospital due to complications and use of systemic antibiotic therapy. Sixty-one patients in 2017 and 59 patients in 2019 met inclusion criteria, and from them, 207 ulcers were included. Between 2017 and 2019, there was a 6.2-week reduction in time to 100% ulcer healing in 2019 (p = 0.021), and 10.1% more ulcers healed within 52 weeks (p = 0.22, 95% confidence interval [CI] [-5.9%, 25.5%]). Whilst there was no significant difference in incidence of patients receiving amputation, there was an increased absolute number of amputations in 2019. Implementation of a multidisciplinary approach at the Gosford Hospital High-Risk Foot Clinic led to improvements in diabetic foot ulcer healing.

Factors influencing diabetes-related foot ulcer healing in Australian adults: A prospective cohort study.

OBJECTIVE: Diabetes-related foot ulceration (DFU) is a common limb-threatening condition, which is complex and subsequently challenging to manage. The aim of this study was to determine the contribution of a range of clinical and social factors to the healing of diabetes-related foot ulceration in an Australian population. RESEARCH DESIGN AND METHODS: This was a prospective cohort study of individuals with diabetes-related foot ulceration (DFU). Age, sex, medical history, medications, dietary supplementation (e.g. vitamin C intake) and smoking history were elicited at baseline. The index of relative socio-economic disadvantage (IRSD) was calculated. The Australian Eating Survey and International Physical Activity Questionnaire-short were administered. Wound history, size, grade, time to healing and infection were captured and monitored over 6 months. Logistic regression was performed to determine the relationship between healing and diet quality, toe systolic pressure, wound size at, IRSD, infection and previous amputation. RESULTS: A total of 117 participants were included. The majority were male n = 96 (82%), socio-economically disadvantaged (mean IRSD 965, SD 60), and obese (BMI 36 kg/m2 , SD 11) with a long history of diabetes (20 years, SD 11). Wounds were predominantly neuropathic (n = 85, 73%) and classified 1A (n = 63, 54%) on the University of Texas wound classification system with few infections (n = 23, 16%). Dietary supplementation was associated with 4.36 increased odds of healing (95% 1.28-14.84, p = 0.02), and greater levels of socio-economic advantage were also associated with increased odds of healing (OR 1.01, 95% CI 1.01-1.02, p = 0.03). CONCLUSIONS: In this cohort study of predominantly neuropathic, non-infected DFU, individuals who had greater levels of socio-economic advantage had significantly greater odds of DFU healing. Diet quality was poor in most participants, with individuals taking supplementation significantly more likely to heal.

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.

Do toe blood pressures predict healing after minor lower limb amputation in people with diabetes? A systematic review and meta-analysis.

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.
