Just a couple of anecdotal personal recent experiences with US healthcare.
1. Recently I witnessed the trouble my primary care physician (PCP) had to go through with insurance company to get approval to perform CT scan. I couldn't believe the 30 minutes, my PCP had to spend on the phone with the United Healthcare person. This is the doctor spending time on the phone explaining all the medical reasons for recommending CT scan and not some administrative person in doctor's office.
This is in contrast to a friend's experience whose PCP kept prescribing pain killers and other prescriptions instead of pushing insurance company for further tests for abdominal pain. The friend later was diagnosed with stage 4 cancer when showed up at ER with same symptoms.
2. While researching a local major hospital rated highly for quality of surgery, I came across the reports of quite a few cancer patients complaining about hospital quickly discharging patients after major surgery and restricting pain medication while in hospital. The claims don't make sense as hospital is rated so highly for Quality of Surgery and might be considered anecdotal. Until I found that two of the measuring criteria for Quality of Surgery was how long a patient stayed in hospital after surgery and dosage and duration of pain medication administered after the surgery. Talk about incentive misalignment. There is all the incentive for surgeon and hospital administration to discharge you quickly to maintain and improve Quality of Surgery rating.
