Health care personnel's perception of guideline implementation for musculoskeletal imaging: a process evaluation

The increasing complexity and variability in radiology have significantly fueled the need for guidelines. There are many methods for disseminating and implementing guidelines however; and obtaining lasting changes has been difficult. Implementation outcome is usually measured in a decrease in unwarranted examinations, and qualitative data are rarely used. This study's aim was to evaluate a guideline implementation process and identify factors influencing implementation outcome using qualitative data.

Seven general practitioners and five radiological personnel from a Norwegian county participated in four focus group interviews in 2019. The data were analyzed using qualitative content analysis, where some categories were predetermined, while most were drawn from the data.

Four main categories were developed from the data material. 1) Successful/unsuccessful parts of the implementation, 2) perceived changes/lack of changes after the implementation, 3) environment-related factors that affected guideline use, and 4) User related factors that affect guideline use.

Our findings show that clinical guideline implementation is difficult, despite the implementation strategy being tailored to the target groups. Several environment- and user-related factors contributed to the lack of changes experienced in practice for both general practitioners and radiological personnel.
