Chapters 3 and 4 discuss further some of the technical, human, and policy factors that may support or impede the successful introduction and widespread adoption of telemedicine applications such as those described here. If those planning for the implementation and evaluation of telemedicine programs are sensitive to these factors, they may be able to minimize certain problems at the outset as well as identify sources of problems that arise when the program becomes operational. The evaluation framework presented later in this report reflects this conclusion.
