Abstract
Increasingly, health and medical communication involves a global perspective. This perspective now includes coordinating international efforts ranging from treating globally dispersed patients to containing infectious diseases. In many cases, the focus of such information is instructional---content that tells individuals how to perform certain health-or medical-related processes. In such situations, usability is essential to success. That is, individuals must be able to use instructional materials as intended to achieve a particular purpose or objective. Communication designers therefore need to identify approaches that can facilitate the usability of health and medical content in a range of international settings.
