Health disparities in individuals with intellectual and developmental disabilities (IDD) are related to a number of factors including poor communication and coordination of care within the health care system. This study reports on findings of a training program aimed at increasing health professionals' knowledge, beliefs, and behaviors related to documentation of IDD within medical records. Results indicate that health professionals report a lack of knowledge about IDD and training was helpful in increasing knowledge of documentation procedures. Using an occupational justice lens, occupational therapy has a role in improving health outcomes of people with IDD by providing education to other health professionals.
