SummaryThis paper examines issues related to applying information technology in behalf of mental health service delivery systems. Each of these issues has an impact on how well information technology has been able to serve the mental health system. These are not primarily information technology issues. They are concerns that have to do with the structure of the mental health system; the way management might use an information system; and the role of money and power in the mental health system. How these issues are resolved will have a major impact on how well the promise inherent in information technology is realized in the coming decade.
