This is a great question. In my practice I continue to refer patients to their PCP for these type of issues. I discuss with patients that primary care and health maintenance guidelines are continually changing and that their PCP is the expert in this field just as we are in oncology.
I agree with Lisa. However, I find that many of the PCPs feel uncomfortable managing some issues and encourage the patient to see their oncology team. In the few instances I have time/opportunity to call the PCP directly to provide just a quick “heads up” – it is so appreciated by the PCP and then they feel more comfortable reaching out to us with any issues. Even with shared EHRs- a phone call really does go a long way as often they have to dig in the notes to figure out what a pt is receiving.
