screening, assessment and prescription in diabetic foot disease
DESCRIPTION
Presentation at the BAPO Conference in Telford 2013. Starts by describing the screening and assessment process for the diabetic foot and the important differences between them. It describes the importance of risk stratification of the individual as this will determine the essential characteristics of the protective footwear for the individual. The key to effective management is to make sure that individuals are treated according to their risk of ulceration. Keeping those at the lowest risk from progressing is vital for cost efffective management. The presentation also describes the nature of the orthotic prescription and how this should relate to the patients risk level.TRANSCRIPT

• Detects early disease
• Involves tests that have a predictive value and an agreed cut-off point for referral
• Requires healthcare worker trained for competence in screening
• Does not involve a treatment plan
• Patient does not influence outcome

Assessment• Establishes a diagnosis
• Involves clinical decision making skills and clinical autonomy for onward referral
• Requires a healthcare professional with the appropriate training/competence in assessment
• Decides on a future management plan
• Patient may influence outcome
• Reassessment is patient-led depending on symptoms or response to therapy

Footwear Design CriteriaSpectrum of Activity
• Newly screened neuropathic foot
• Moderate Risk
• Non-ulcerated
• Deformed neuro-ischaemic foot
• High Risk• Previous Ulceration

• Shoe and Contact Surface (footbed) Must Work Together
• Materials & Structures Chosen & Positioned for BOTH Control and Tissue Matching
• Shoes Need to act like the “Skeleton” as well as the “Soft Tissues” - Support as well as protect
• “Soft” Uppers not Necessarily Best - Match to the Ambulatory Status and Load Expectations

Conclusion
• Base on individual patient needs
• Materials to suit the interfaces
• Don’t design the foot orthosis without thinking of the shoe
• Multi-disciplinary education and mutual understanding of orthotic interventions
