Clinical protocols are introduced in hospitals to standardize the care delivery process. Compliance is a measure used to determine whether the protocol has been followed. However compliance measures do not provide enough insight to be used in daily practice. In this paper we propose to use linguistic summaries to analyze the compliance to clinical protocols. As our case we examine a glucose management protocol at ICU. We will demonstrate that linguistic summaries can provide insight, that is actionable and comprehensible by the health-care providers.
