While serving as a physician overseas in resource-poor countries, Dr. James Chambers recognized the need for a practical, portable reference for non-specialist healthcare providers to orient them to common issues when serving in new situations, whether due to geography, austere environments, or complex humanitarian disasters. Field Guide to Global Health and Disaster Medicine draws on the experience, training, and perspectives of committed healthcare providers from diverse nations and backgrounds to provide the most essential information for maximum utility in the field-whether in a refugee camp, operating room, disaster response scene, or other demanding environment.
