Role of Point-of-Care Diagnostics in Lower- and Middle-Income Countries and Austere Environments

Introduction: Austere environments include the wilderness and many lower- and middle-income countries, with many of these countries facing unrest and war. The access to advanced diagnostic equipment is often unaffordable, even if available, and the equipment is often liable to break down. Methods: A short review paper examining the options available to medical professionals to undertake clinical and point-of-care diagnostic testing in resource-constrained environments that also illustrates the development of mobile advanced diagnostic equipment. The aim is to provide an overview of the spectrum and functionality of these devices beyond clinical acumen. Results: Details and examples of products covering all aspects of diagnostic testing are provided. Where relevant, reliability and cost implications are discussed. Conclusions: The review highlights the need for more cost-effective accessible and utilitarian products and devices that will bring cost-effective health care to many in lower- and middle-income or austere environments.
