Abstract

The implementation of a data warehouse and a decision support system by utilising the capabilities of information retrieval and knowledge discovery tools in the healthcare fields has allowed for the enhancement in the offered healthcare. In this work, we present a review of recent data warehouses and decision support systems in the healthcare domain with their significance, and applications of evidence-based medicine, electronic health records, and nursing. Given the growing trend on their implementation in healthcare services, researches, and education, we present here the most recent publications that employ these tools to produce suitable decisions for patients or health providers. For all the reviewed publications, we have intensively explored their problems, suggested solutions, utilised methods, and their findings. We have also highlighted the strength of the existing approaches and identified potential drawbacks including data correctness, completeness, consistency, and integration to provide proper medical decision-making.
