Prevalence and incidence of peripheral neuropathy, peripheral artery disease, foot disease, and lower extremity amputation in people with diabetes in Ireland; a systematic review protocol.

Introduction: Internationally, the prevalence of diabetes is increasing, and with this comes an increase in diabetes related complications. Diabetic foot disease is the most common lower extremity complication in people with diabetes causing 2% of the global disease burden. It, is associated with major morbidity, mortality, and costs to health services. Despite this burden, the incidence and prevalence of diabetic foot disease is unknown in Ireland. This paper presents a protocol for a systematic review to examine the incidence and prevalence of diabetic foot disease in the Irish population. Methods: A systematic review will be performed using the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Pubmed, EMBASE, and Lenus, the Irish Health Research repository, will be searched for publications in any language and without restrictions to date. Title, abstract, and full text screening will be carried out independently by two investigators. Publications reporting on the incidence or prevalence of peripheral neuropathy, peripheral artery disease, ulceration, or amputation in people with diabetes in Ireland, from a defined geographical catchment area of Ireland, will be included. Joanna Briggs Institute (JBI) Critical Appraisal tool will be used to assess included studies methodological quality. Results will be reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Conclusion: The results of this systematic review can be used to inform appropriate stakeholders on the incidence and prevalence of diabetic foot disease in Irish populations, enabling decision making around appropriate use of resources to help prevent, and improve management of this disease. Systematic review registration: CRD42023472904.
