Diabetes foot screening: Challenges and future strategies

Australian guideline on prevention of foot ulceration: part of the 2021 Australian evidence-based guidelines for diabetes-related foot disease

BACKGROUND

There are no current Australian guidelines on the prevention of diabetes-related foot ulceration (DFU). A national expert panel aimed to systematically identify and adapt suitable international guidelines to the Australian context to create new Australian evidence-based guidelines on prevention of first-ever and/or recurrent DFU. These guidelines will include for the first-time considerations for rural and remote, and Aboriginal and Torres Strait Islander peoples.

METHODS

The National Health and Medical Research Council procedures were followed to adapt suitable international guidelines on DFU prevention to the Australian health context. This included a search of public databases after which the International Working Group on the Diabetic Foot (IWGDF) prevention guideline was deemed the most appropriate for adaptation. The 16 IWGDF prevention recommendations were assessed using the ADAPTE and GRADE systems to decide if they should be adopted, adapted or excluded for the new Australian guideline. The quality of evidence and strength of recommendation ratings were re-evaluated with reference to the Australian context. This guideline underwent public consultation, further revision, and approval by national peak bodies.

RESULTS

Of the 16 original IWGDF prevention recommendations, nine were adopted, six were adapted and one was excluded. It is recommended that all people at increased risk of DFU are assessed at intervals corresponding to the IWGDF risk ratings. For those at increased risk, structured education about appropriate foot protection, inspection, footwear, weight-bearing activities, and foot self-care is recommended. Prescription of orthotic interventions and/or medical grade footwear, providing integrated foot care, and self-monitoring of foot skin temperatures (contingent on validated, user-friendly and affordable systems becoming available in Australia) may also assist in preventing DFU. If the above recommended non-surgical treatment fails, the use of various surgical interventions for the prevention of DFU can be considered.

CONCLUSIONS

This new Australian evidence-based guideline on prevention of DFU, endorsed by 10 national peak bodies, provides specific recommendations for relevant health professionals and consumers in the Australian context to prevent DFU. Following these recommendations should achieve better DFU prevention outcomes in Australia.

Measuring sustainability in healthcare: an analysis of two systems providing insoles to patients with diabetes

There is an increasing demand to quantify the footprints, ecological, economic and social, in terms of the effect of different interventions in healthcare. The aim of this study was to compare two systems providing patients with diabetes with insoles in terms of their ecological, economic and social footprints. Prefabricated insoles (PRI) were compared with custom-made insoles (CMI). Using a welfare-economic monetary approach, costs were estimated for (1) treatment, (2) travelling to and from the hospital in terms of both fuel and time consumed by the patients and (3) society through emissions contributing to climate change. The proportion of patients/year that could be supplied within the same budget, for each individual treatment, was calculated. The cost of the insoles was 825 SEK (PRI) and 1450 SEK (CMI), respectively. The cost, mean value/patient due to the consumption of patients' time at the department, was 754 SEK (PRI) and 1508 SEK (CMI), respectively. Emissions, in terms of CO₂ equivalent, were 13.7 (PRI) and 27.4 (CMI), respectively. Using PRI, a total of 928 patients could be provided/year compared with 500 patients if CMI are used. By using PRI, the cost/treatment was reduced by 46%. The cost of treatment dominated and the cost of time consumed by patients were also substantial. The societal cost of contributing to climate change was of low importance. By using PRI, the needs of 86% more patients could be met within the same budget. Using these methods, the contribution of healthcare systems to the 17 Sustainable Development Goals approved by the UN can be quantified.

Barriers and enablers to providing preventative and early intervention diabetes-related foot care: a qualitative study of primary care healthcare professionals' perceptions

This study explored the perceived healthcare system and process barriers and enablers experienced by GPs and Credentialled Diabetes Educators (CDEs) in Australian primary care, in the delivery of preventative and early intervention foot care to people with diabetes. A qualitative design with inductive analysis approach was utilised and reported according to the Consolidated Criteria for Reporting Qualitative Studies (COREQ). Semi-structured interviews were conducted with two GPs and 14 CDEs from rural, urban and metropolitan areas of Australia. Participants were from New South Wales, South Australia, Victoria, Western Australia, the Northern Territory and Queensland. Barriers to providing foot care constituted five broad themes: (1) lack of access to footcare specialists and services; (2) education and training insufficiencies; (3) human and physical resource limitations related to funding inadequacies; (4) poor care integration such as inadequate communication and feedback across services and disciplines, and ineffectual multidisciplinary care; and (5) deficient footcare processes and guidelines including ambiguous referral pathways. Enablers to foot care were found at opposing ends of the same spectra as the identified barriers or were related to engaging in mentorship programs and utilising standardised assessment tools. This is the first Australian study to obtain information from GPs and CDEs about the perceived barriers and enablers influencing preventative and early intervention diabetes-related foot care. Findings offer an opportunity for the development and translation of effective intervention strategies across health systems, policy, funding, curriculum and clinical practice, in order to improve outcomes for people with diabetes.
