title: Workflow-based Data Reconciliation for Clinical Decision Support: Case of Colorectal Cancer Screening and Surveillance.
abstract: A major barrier for computer-based clinical decision support (CDS), is the difficulty in obtaining the patient information required for decision making. The information gap is often due to deficiencies in the clinical documentation. One approach to address this gap is to gather and reconcile data from related documents or data sources. In this paper we consider the case of a CDS system for colorectal cancer screening and surveillance. We describe the use of workflow analysis to design data reconciliation processes. Further, we perform a quantitative analysis of the impact of these processes on system performance using a dataset of 106 patients. Results show that data reconciliation considerably improves the performance of the system. Our study demonstrates that, workflow-based data reconciliation can play a vital role in designing new-generation CDS systems that are based on complex guideline models and use natural language processing (NLP) to obtain patient data.
