A comprehensive resource describing innovative technologies and digital health tools that can revolutionize the delivery of health care in low- to middle-income countries, particularly in remote rural impoverished communities
 
Revolutionizing Tropical Medicine offers an up-to-date guide for healthcare and other professionals working in low-resource countries where access to health care facilities for diagnosis and treatment is challenging. Rather than suggesting the expensive solution of building new bricks and mortar clinics and hospitals and increasing the number of doctors and nurses in these deprived areas, the authors propose a complete change of mindset. They outline a number of ideas for improving healthcare including rapid diagnostic testing for infectious and non-infectious diseases at a point-of-care facility, together with low cost portable imaging devices. In addition, the authors recommend a change in the way in which health care is delivered. This approach requires task-shifting within the healthcare provision system so that nurses, laboratory technicians, pharmacists and others are trained in the newly available technologies, thus enabling faster and more appropriate triage for people requiring medical treatment.
 
This text:
* Describes the current burden of communicable and non-communicable diseases in low- to middle-income countries throughout the world
* Describes the major advances in healthcare outcomes in low-to middle-income countries derived from implementation of the United Nations/World Health Organisation's 2000 Millennium Development Goals
* Provides a review of inexpensive rapid diagnostic point-of-care tests for infectious diseases in low-resource countries, particularly for people living in remote rural areas
* Provides a review of other rapid point-of-care services for assessing hematological function, biochemical function, renal function, hepatic function and status including hepatitis, acid-base balance, sickle cell disease, severe acute malnutrition and spirometry
* Explores the use of low-cost portable imaging devices for use in remote rural areas including a novel method of examining the optic fundus using a smartphone and the extensive value of portable ultrasound scanning when x-ray facilities are not available
* Describes the use of telemedicine in the clinical management of both children and adults in remote rural settings
* Looks to the future of clinical management in remote impoverished rural settings using nucleic acid identification of pathogens, the use of nanoparticles for water purification, the use of drones, the use of pulse oximetry and the use of near-infrared spectroscopy
* Finally, it assesses the potential for future healthcare improvement in impoverished areas and how the United Nations/World Health Organization 2015 Sustainable Development Goals are approaching this.
 
Written for physicians, infectious disease specialists, pathologists, radiologists, nurses, pharmacists and other health care workers, as well as government healthcare managers, Revolutionizing Tropical Medicine is a new up-to-date essential and realistic guide to treating and diagnosing patients in low-resource tropical countries based on new technologies.
