Isn't there some kind of oversight or someone at the top who can fire doctors who overtreat their patients? I feel like the department head of any hospital should have a responsibility to make sure none of his/her doctors are partaking in these immoral practicies.
Its not immoral. You got a guy with a big lung mass. You put him on chemo. He tolerated it well, with minimal weight loss and other side effects. On followup scans, the tumor has gotten considerably smaller, but theres a small nodule left. What's immoral about giving another few weeks of chemo to blast that sucker away?
No top doctor anywhere should have to take "responsibility" for the way another doctor practices medicine.
Especially in oncology no department head should dictate how the individual attendings practice. There is an art to oncology, and each oncologist has their own style. It takes years of expereince for them to be able to gauge when it's better to push forward, and when to pull back. There isn't any sort of etched-in-stone treatment protocol that will tell you how to manage your individual patient. Oncologists should be valued for their individual expertise, and not be told what to do by the department chair.
Within the heme/onc practice that I rotated in, each oncologist had their own style, and own expertise. There was even a patient or two that switched oncologists within the practice because one or the other had more experience with and was more willing to give aggressive chemo (and treat the side effects), while one thought it wouldn't be safe. Same patient, two opinions. Who was correct, only time could tell. So, as always, it was up to the patient.
Imagine a patient going in for his monthly followup...
"Hi, Im here to see Dr Doe."
"Oh, we fired him, You'll see Dr. Smith instead."
"But Ive been seeing Dr Doe for a year, Hes treating my colon cancer."
"Yeah, we fired him because he gave Ms. Jones two additional rounds of chemo for her lung cancer."
"Oh, did Ms Jones die?"
"No."
"Oh, thats grand. Now, Im here to see Dr Doe he's been tailoring my treatment for a year now"
"Im sorry, you'll see Dr Smith. He has an appointment opening. His patient Mr. Baker died yesterday."
"Oh, Im sorry to hear that, I'd just talked to Mr Baker last month in the waiting room. Too much chemo, no doubt?"
"No, Mr Baker just got the usual course. Well, Dr Smith is ready for you. Best of luck now."
