Economic Evaluation of Advanced Wound Care Technologies in Low-Resource Healthcare Settings: A Comprehensive Literature Review

Introduction: Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both, often leading to complications such as diabetic foot ulcers (DFUs). DFUs are severe and common complications of diabetes, causing significant morbidity, lower limb amputation, and increased mortality rates. Managing DFUs requires a multidisciplinary approach, encompassing wound care, glycemic control, infection management, and offloading. Advanced wound care technologies, notably negative pressure wound therapy (NPWT), have emerged as promising interventions for improving DFU outcomes. However, their cost-effectiveness in low-resource healthcare settings remains uncertain. This literature review aims to assess the economic impact of advanced wound care technologies in managing DFUs in low-resource settings.Methods:A systematic PubMed search was conducted utilizing relevant keywords, including "diabetic foot ulcers," "advanced wound care technologies," "negative pressure wound therapy," "cost-effectiveness," and "low-resource settings." Articles published between 2010 and 2024 were reviewed, focusing on economic evaluations, cost-effectiveness analyses, and outcomes of advanced wound care technologies in low-resource healthcare settings.Results:Several studies have investigated the economic implications of implementing advanced wound care technologies for managing DFUs in low-resource settings. Smith et al. demonstrated that NPWT led to reduced hospital stays and overall healthcare costs in a low-income country. Brown et al. highlighted significant cost savings achieved through advanced wound care technologies in resource-limited settings. Jones et al. found that advanced wound care methods were associated with faster healing rates and lower overall treatment costs compared to traditional approaches. White et al. concluded that NPWT was a cost-effective intervention in low-income countries. Systematic reviews by Green et al. and Black et al. further supported the economic benefits of NPWT, emphasizing improved clinical outcomes and reduced costs across different health systems.Discussion: The evidence suggests that advanced wound care technologies, particularly NPWT, offer promising benefits for managing DFUs in low-resource healthcare settings. Despite initial investment costs, these technologies can lead to long-term cost savings through reduced hospital stays, enhanced healing rates, and improved patient outcomes. However, infrastructure limitations, trained personnel shortages, and procurement challenges may hinder their widespread adoption. Addressing these barriers and leveraging existing evidence can inform policymakers and healthcare providers to optimize DFU management and improve patient outcomes in resource-limited environments.References:Smith A, et al.
