The document discusses the challenges of implementing a health information technology (HIT) system. It outlines several stakeholder groups - including inpatient systems, outpatient systems, regional health information organizations, physicians, patients, payers, and policymakers - and analyzes the challenges each group faces. Inpatient systems face the largest challenges due to high costs of hardware, software, and staff training. Physicians could see reduced income if the system reduces unnecessary tests and procedures. However, patients and payers may realize reduced costs from avoiding duplicate and harmful services. The document argues incentives must be structured to encourage stakeholders to work together to maximize the benefits of investing in HIT.
