The challenge of involving elderly patients in primary care by using an electronic communication tool with their professionals: a mixed methods study.

Congredi was usable for patient-systems. The barriers found seem not to be tool-related but primarily user-related. An important barrier for daily use was limited active participation of involved professionals in a complete feedback loop. Potential for future implementation was found, as patient-systems were intrinsically motivated for better feedback with the professionals, even though in this study it only partly met their expectations.
