    Formalizing UMLS Relations Using Semantic Partitions in the Context of a Task-Based Clinical Guidelines Model.Anand Kumar, Matteo Piazza, Barry Smith, Silvana Quaglini & Mario Stefanelli - 2004 - In IFOMIS Reports. Saarbrücken: IFOMIS.
    An important part of the Unified Medical Language System (UMLS) is its Semantic Network, consisting of 134 Semantic Types connected to each other by edges formed by one or more of 54 distinct Relation Types. This Network is however for many purposes overcomplex, and various groups have thus made attempts at simplification. Here we take this work further by simplifying the relations which involve the three Semantic Types – Diagnostic Procedure, Laboratory Procedure and Therapeutic or Preventive Procedure. We define operators (...)

    Implementing Clinical Guidelines in an Organizational Setup.Anand Kumar, Barry Smith, Mario Stefanelli, Silvana Quaglini & Matteo Piazza - 2003 - In Proceedings of the Workshop on Model-Based and Qualitative Reasoning in Biomedicine, AIME . pp. 39-44.
    Outcomes research in healthcare has been a topic much addressed in recent years. Efforts in this direction have been supplemented by work in the areas of guidelines for clinical practice and computer-interpretable workflow and careflow models.In what follows we present the outlines of a framework for understanding the relations between organizations, guidelines, individual patients and patient-related functions. The derived framework provides a means to extract the knowledge contained in the guideline text at different granularities, in ways that can help us (...)

    Clinical Guidelines as Plans: An Ontological Theory.Anand Kumar, Barry Smith, Domenica Pisanelli, Aldo Gangemi & Mario Stefanelli - 2006 - Methods of Information in Medicine 45 (2):204-210.
    Clinical guidelines are special types of plans realized by collective agents. We provide an ontological theory of such plans that is designed to support the construction of a framework in which guideline-based information systems can be employed in the management of workflow in health care organizations. The framework we propose allows us to represent in formal terms how clinical guidelines are realized through the actions of are realized through the actions of individuals organized into teams. We provide various levels of (...)
