My interpretation is he feels medication is pushed too much and rarely solves the problem. He mentioned how people wanted to taper off and eventually stop taking prescription medication. He didn't like how he isn't allowed to help with that area.
Also he voiced how the cost difference for someone staying in the hospital as an impatient is very high compared to seeing him. Insurance will try to prevent patients from seeing him 3 days per week and only want once a week (even if 3 days is helpful). Insurance companies have every detail about a patient and demand it without respecting privacy.
It's also a way to be able to talk to someone else about their cases. The person they go to is themselves bound by confidentiality restrictions so they can talk about whatever they need to without worrying that patients' communications will be leaked.
That's an important point because this group of people often find themselves medicated with a range of different drugs - valproate, quetiapine, lamotrigine, topiramate, carbamazepine, lithium, benzos, z drugs, SSRIs, etc etc, but there's little evidence that these meds provide any benefit for this group of people.
(I'm not anti-medication.)
