This IBI report features the productivity implications of poorly managed diabetes drawing upon IBI’s 2013 Benchmarking data, prior IBI studies and others’ research. Together these findings suggest that when diabetes is managed well work-disruptive symptoms and events -- such as attendance problems, fatigue-related performance issues and work disability episodes -- are likely to diminish. Value-based plan designs that support reliable treatment and monitoring methods for better control of blood glucose levels are expected to lessen these types of negative work outcomes.
