Quality of primary care delivery and productive interactions among community-living frail older persons and their general practitioners and practice nurses.

Frail community-dwelling older persons' perspectives on quality of primary care were associated with perceived productivity of their interactions with the GP and practice nurse in both the intervention group and the control group. We found no significant differences in overall perceived quality of care and perceived patient-professional interaction between the intervention group and control group at baseline and follow-up. In times of population aging it is necessary to invest in high-quality care delivery for frail older persons and productive interactions with them.
