To map the diffusion of PET-CT technology in France (2013–2022) and identify the multi-level contextual factors explaining its uneven diffusion and utilization.
Approach:
Key Findings:
The supply of PET-CT technology has expanded nationwide, indicating a positive trend in availability.
Actual use of PET-CT varies significantly between regions, a disparity not explained by supply or epidemiological demand, highlighting potential inequities.
The 'supply-use' gap is influenced by institutional, organizational, and professional factors, suggesting a need for targeted interventions.
Interpretation:
The diffusion of PET-CT in France is a complex process influenced by local contexts, challenging the notion of a purely rational model of technology adoption and emphasizing the role of socio-political dynamics.
Limitations:
The study may not capture all regional variations in PET-CT utilization, potentially overlooking critical local factors.
Potential biases in stakeholder interviews, such as selection bias or response bias, may affect findings and interpretations.
Conclusion:
Understanding the determinants of PET-CT diffusion is crucial for developing equitable health policy in nuclear medicine, as it can inform strategies to address disparities in access and utilization.
