The increased need for interoperable electronic health records in health care organizations underscores the importance of standards. The US Department of Veterans Affairs (VA) has a long history of developing and adopting various types of health care data standards. The authors present in detail their experience in this domain. A formal organization within VA is responsible for helping to develop and implement standards. This group has produced a Standards Life Cycle (SLC) process endorsed by VA key business and information technology (IT) stakeholders. It coordinates the identification, description, and implementation of standards aligned with VA business requirements. In this paper, we review the adoption of four standards in the categories of security and privacy, terminology, health information exchange, and modeling tools; emphasizing the implementation approach used in each. In our experience, adoption is facilitated by internal staff with expertise in standards development and adoption. Use of processes such as an SLC and tools such as an enterprise requirement repository help formally track and ensure that IT development and acquisition incorporate these standards. An organization should adopt standards that are aligned with its business priorities and favor those that are more readily implementable. To assist with this final point, we offer a standard "Likelihood of Adoption Scale," which changes as standards specifications evolve from PDF documents only, to PDF documents with construction and testing tools, to fully functional reference implementations.

Clarified and dialyzed mixed saliva-water rinses, obtained from patients receiving radiation treatment of the major salivary glands, exhibited quantitative reductions in total protein content and qualitative changes in protein composition. Radiation or post-radiation saliva preparations supported enhanced growth of Streptococcus mutans, but reduced growth of Streptococcus sanguis relative to growth on pretreatment saliva.
