Some online resources, such as publication databases, are continuously updated. In the case of websites, including the date the content was last revised can show users how current the information is. There are also organizations that evaluate health information, such as The Health on the Net (HON) Foundation, which applies the HONcode (The Health on the Net Foundation Code of Conduct) to medical and health websites. (For more information, see the HON website: http://www.hon.ch/). In addition to adding research findings and lessons learned, one might need to respond to changing content needs in the field, such as a new disease outbreak in a region or the introduction of a new or new use of information technology, such as SMS used to return HIV test results to clinics. Knowledge generation is a continuous process, and KM resources/outputs should be designed as living tools that can be modified and supplemented as needed. These updates and modifications keep KM outputs valuable to users and help ensure that they continue to have an impact on programs.
