For
instance, the process model proposed by Carayon et al. [72] would
be of great help to deepen our understanding of how EHR usage in
medical practices affects work processes (clinical and administra-tive) and the consequent individual and organizational outcomes.
Finally, in addition to functional coverage and ease of use it would
seem important to consider perceived usefulness as another key
antecedent in future models; as is usually done in information systems
and medical informatics acceptance research.
