Environmental Factors on DFUs Incidence - a Mixed-mode Survey

Active, not recruiting

• Conditions: Diabetic Foot Ulcer; Diabetic Foot

• Registration Number: NCT05464524
• Lead Sponsor: King's College London

Brief Summary

Diabetic foot ulcers (DFUs) pose a significant threat to the health and wellbeing of diabetic patients. Affecting around 1 in 10 people (NHS North West Coast Strategic Clinical Networks, 2017) regardless of a diabetes type they often result in a drastically worsened quality of life and can lead to severe consequences including leg amputations. This survey will help to understand what role various environmental factors have on the incidence, severity and recurrence of DFUs. Results from this study will help healthcare professionals as well as patients to better understand various factors involved in DFU prevalence. Moreover, this survey could help to appreciate whether a more holistic approach should be followed when assessing DFU risk and deciding on therapy. This study will be run across five sites in England between October 2023 and May 2024 and will involve a small pilot study (informal interview) and an anonymous, ten-minute questionnaire. Any adult with an ongoing or past DFU will be eligible. Participants will be asked about their job type, quality of life, diabetic therapy, comorbidities, and environmental factors questions. There will be an option for a follow-up questionnaire after 12 weeks to understand the healing process and changes to the quality of life following a DFU incident. Additionally, patients may consent to provide access to excerpts from their anonymized medical history details (prescribed medications) to better understand their diabetic and DFU history. This study will be run as part of an industrial, London Interdisciplinary Biosciences Consortium (LIDo) PhD project investigating the autologous platelet-rich plasma gel for diabetic foot ulcers (RAPID™ biodynamic haematogel) with King's College London as funded by the Biotechnology and Biological Sciences Research Council (BBSCR) and Biotherapy Services Ltd.

Primary Outcome Measures

Name	Time	Method
Established the role of tested environmental factors and lifestyle choices on the incidence, recurrence, and severity of diabetic foot ulcers in adults living with diabetes in England.	9 months	Descriptive statistics used to characterise the study population. Logistic regression modelling of tested environmental factors to establish models quantifying the association between independent and dependent variables (DFU incidence, severity, recurrence).; Identified main environmental factors that produce the highest probability of having a severe diabetic foot ulcer case (based on the answers to the EQ-5D-5L - a severe DFU incident would is predicted to influence mobility, self-care, pain levels, performance of usual activities and anxiety/depression.)

Secondary Outcome Measures

Name	Time	Method
Quantified the associations between the other disease co-occurring with diabetes and the medications or therapies prescribed for them that may have an impact on diabetic foot ulcer incidence and severity.	9 months	- Logistic regression models obtained to understand the association between diabetic comorbidities/prescribed medications and the characteristics of a diabetic foot ulcer (severity and recurrence).
Established changes to DFU status and quality of life over the 12 week follow up period.	9 months	Quantified the change in quality of life over 12-week period and testing the association by performing a t-test between the DFU incident outcome and quality of life (based on the answers to the EQ-5D-5L).
