Table 1 Five elements to be considered in the diffusion of innovation theory

Relative advantage

The degree to which an innovation is perceived as better than the idea it supersedes.

Compatibility

The degree to which an innovation is perceived as being compatible with existing values, past experiences, and the needs of potential adopters.

Complexity:

The degree to which an innovation is perceived as difficult to understand and use. A clinical procedure is more likely to be adopted if it is simple and well defined.

Trialability

The degree to which the innovation may be piloted to explore the implementation of the procedure, its acceptability to patients, and the potential outcomes.

Observability

The degree to which the results of the innovation are visible to others.
