Data on motivators and barriers to participation in trials of new medications of older adults with multimorbidity are needed.

Software reuse reference model approach in developing an automated medical information system (AMIS) for improving health care practice.

Objective: To evaluate patient acceptance of an automated medical information system specific to headache.

Background: Studies suggest that automated tools may help health care delivery systems to be efficient and effective, but patient satisfaction remains a major concern.

Methods: We adapted our software reuse reference model and Unified Modeling Language to apply the domain model to the headache population.
