Background: Oldest-old persons frequently receive potentially inappropriate medication. Medication use takes place under the patients' informal caregivers' influence. We explored informal caregivers' perspectives on medication of (relatively) independent oldest-old persons to identify starting points for safer medication prescription/handling.; Methods: In this exploratory qualitative interview study we interviewed 45 informal caregivers of 45 oldest-old persons (23 with potentially inappropriate medication/22 without potentially inappropriate medication).
