The National Cancer Institute's (NCI's) Cancer Information Service (CIS) provides cancer information to the public via 1-800-4-CANCER, a smoking quitline, and online. The 2003 National User Survey assessed satisfaction and outcomes among users contacting NCI's CIS by telephone and LiveHelp, an instant messaging service. Ninety-five percent of respondents were very satisfied/satisfied and 88% said their expectations had been met/exceeded. Users reported increased knowledge and self-efficacy. Most had discussed CIS information with a health professional or planned to do so. Of those who contacted CIS about smoking/tobacco use, 14% had quit and 35% cut back. The CIS provides a highly valued, effective service for patients and health professionals.
"accelerating the adoption of effective innovations, whether in sponsoring large-scale field demonstrations of innovations with developmental costs that are too high for single companies , creating clearinghouses of information for dissemination , improving search capacities for retrieval of scientific data across many databases in parallel , or portraying sets of effective programs from which potential adopters are encouraged to pick and choose . In cancer communication, these efforts have included helping establish phone-based tobacco quitlines in every state , helping states apply evidence-based communication interventions like small media and client reminders to promote colorectal cancer screening (CDC), and forming partnerships with minority serving community agencies to adopt evidence-based cancer control programs to help eliminate health disparities  .

[Show abstract][Hide abstract] ABSTRACT: The best innovations in cancer communication do not necessarily achieve uptake by researchers, public health and clinical practitioners, and policy makers. This paper describes design activities that can be applied and combined for the purpose of spreading effective cancer communication innovations.
A previously developed Push-Pull-Infrastructure Model is used to organize and highlight the types of activities that can be deployed during the design phase of innovations. Scientific literature about the diffusion of innovations, knowledge utilization, marketing, public health, and our experiences in working to spread effective practices, programs, and policies are used for this purpose.
Attempts to broaden the reach, quicken the uptake, and facilitate the use of cancer communication innovations can apply design activities to increase the likelihood of diffusion. Some simple design activities hold considerable promise for improving dissemination and subsequent diffusion.
Augmenting current dissemination practices with evidence-based concepts from diffusion science, marketing science, and knowledge utilization hold promise for improving results by eliciting greater market pull.
Inventors and change agencies seeking to spread cancer communication innovations can experience more success by explicit consideration of design activities that reflect an expanded version of the Push-Pull-Infrastructure Model.
[Show abstract][Hide abstract] ABSTRACT: This paper considers the problem of finding a robust servomechanism controller which achieves exact asymptotic tracking and regulation for a given class of reference and disturbance signals, and arbitrarily good approximate asymptotic regulation for other classes of reference and disturbance input signals. Necessary and sufficient conditions for the existence of such a controller, and a characterization of controllers which accomplish this are given. An explicit algorithm for such controllers is also given; in particular, it is shown that the design of such a controller can always be accomplished by using the cheap control design method as used in  for the multivariable robust servomechanism problem. A degenerate type of robust servomechanism controller (called a high gain servomechanism controller) consisting of only static feedback gains, is also given, which has the property that it produces arbitrarily good approximate regulation for all tracking/disturbance signals; thus this controller shows that dynamics in the feedback controller are not essential for achieving good approximate error regulation. Some numerical examples are included to illustrate the results.

[Show abstract][Hide abstract] ABSTRACT: Smoking contributes to many health problems including cancers and heart and lung diseases. People trying to quit smoking can be helped with medication or through behavioural support such as specialist counselling and group therapy. Support, information and counselling are offered either face-to-face or by telephone. Counselling via telephone hotlines can be provided as part of a programme or separately, and can potentially reach large numbers of people. Our review of trials found telephone counselling to be effective; multiple sessions are likely to be most helpful .
