Quality measurement and reporting are becoming the ticket to incentives, malpractice premium credits, telecommunications discounts, and many other forms of support for adopting electronic health records and other clinical IT. However, increasing interest in quality measurement and reporting is drawing attention to the need for more accurate, consistent, and timely data. The Sarbanes-Oxley (SOX) Act of 2002 created a sense of urgency for senior executives in publicly traded companies to take an active interest in their information assets. The importance of good data stewardship spawned by SOX is trickling down to the private sector, and particularly to health care. Although the observation was made in relationship to businesses managing SOX compliance, with the exception of a duality of ownership that exists in personal health information, the observation applies equally well to health care: Good data stewardship makes good business sense.
