The Workgroup on the National Health Information Infrastructure (NHII) wishes to thank its colleagues on the National Committee on Vital and Health Statistics (NCVHS) for their many contributions to this report. The report — and indeed, the Workgroup itself — was initiated by the former NCVHS Chair, Don Detmer, at a time when few people championed linkages between the healthcare sector, public health, and the public. Under the subsequent leadership of John Lumpkin, as Chair of both the NCVHS and the Workgroup, the NHII vision was developed and the strategic leadership requirements were defined. The Workgroup is grateful to the experts and organizations whose invaluable suggestions shaped the report's recommendations. Development of the report was coordinated by the Office of Disease Prevention and Health Promotion of the U. S. Department of Health and Human Services (HHS), which staffed the Workgroup. The HHS National Center for Health Statistics, Centers for Disease Control and Prevention, serves as Executive Secretary to the Committee and provides logistical and staff support. The Office of the Assistant Secretary for Planning and Evaluation serves as Executive Staff Director of the Committee and coordinates departmental staffing.
