Wrt oncology, and in this case, breast cancer care... Here's one example of one patient's care.
A friend was diagnosed with breast cancer last summer. She has Medicaid. I drive her to and from her appointments. She was referred through her primary care provider / family practice doctor for her mammogram, which was followed by an ultrasound, followed by a biopsy. There followed a breast MRI. Cancer was identified and confirmed, stage 1.
After a case review involving the oncologist, surgeon, and radiologist, it was decided by the oncologist (who is in charge of treatment) that friend would have surgery first, followed by chemotherapy for three months, followed by one dose of radiation.
Friend did ECG, and had various other procedures, lab tests, and other testing done, including injection of dye before surgery, and insertion of port for chemo before chemo began.
The oncologist's practice employs nurse navigators who deal with insurance companies, provide support/ hand holding for patients, and co-ordinate all appointments. My friend has never had to make a single phone call to make an appointment. The nurse navigator checked with friend about available times (she works part time) for procedure/appointments, so there was never a question of a conflict. She has never had to contact her Medicaid plan admin for anything. The nurse navigator has done all of that, including getting an alternative nausea medication authorised when the first one prescribed caused a reaction. I had offered her this support and it turned out to be completely unnecessary.
On top of all this, she has a dedicated oncology nurse who sees her every time for her treatment. They have developed a good rapport. The level of support offered by the oncologist's staff is exemplary imo. (And while I drive her to and from her appointments, she could avail of free transport directly from home to the chemo centre and back if she wanted it).
Again, Medicaid patient, urban area, blue state.
