Development of a tool to support general practitioners to help adolescents with knee pain: an analysis using the Theoretical Domains Framework.

One of the biggest challenges from the general practitioner's perspective was how to manage and guide adolescents with non-traumatic knee pain. The doctors had doubts in their capability to diagnose knee pain and saw opportunity to help structure the consultation. The doctors felt motivated to use a tool but considered access a potential barrier. Increasing opportunity and motivation by creating access in the community among general practitioners was considered important. We identified several barriers and facilitators for a support tool for the management of adolescent non-traumatic knee pain in general practice. To align with user needs, future tools should support diagnostic workup, structure the consultation and be easily available among doctors working in general practice.
