Knowledge of barriers to CGA is necessary in order to design and implement effective strategies to widen its availability to all whom it could benefit. Social determinants of health and insurance type are associated with delays in authorization for CGA. Families with public insurance and HMO coverage experience delays in obtaining insurance authorization compared to PPO/self-pay patients, whose tests did not require prior authorization. However, there can also be delays in scheduling and completing CGA once authorized. This is a multi-faceted issue that requires further research.
