The US government is set to invest $19 billion in incentive grants to support meaningful use of electronic medical record (EMR) systems. EMR systems can give healthcare administrators and clinicians the information necessary to improve patient care and lower costs. The authors identify critical success factors for EMR systems implementation by treating them as a type of enterprise resource planning (ERP) system. They address EMR implementation issues by drawing on theory and empirical research from both the healthcare information systems and ERP literatures and qualitatively test their model for implementation success.
