Few quick thoughts on this.
First, there is a fundamental incentive problem with privatized healthcare along with other industries like private prisons and education which is why I personally strongly support the public sector in those utilities.
The goal of a health care system to provide the most efficient, effective health care to all the citizens. For-profit HMO/pharmaceutical entities have a fiduciary duty to maximize profit for shareholders. This automatically creates a disconnect of incentives in many circumstances. There are inevitably going to be decision points where the profit incentive goes against what is actually the most efficient healthy solution. In every industry there is the danger of
planned obsolescence when the focus is too heavily on maximizing profit but in health care planned obsolescence can really have some negative consequences that go directly against the goal of efficient health care systems.
This classic article is a great example of many of the misaligned incentive problems that happen with the current US privatized HMO system:

Second, the wealth of research from dozens of behavioral economics researchers over the last 3 decades shows that neo-classical economics assumptions about motivation, decision making and behavior are not as reducible to the profit motive as early classical economists assumed. A lot of good exprriments on intrinsic vs extrinsic motivation.
Good overview here:
"Contrary to what you would expect based on a standard introductory text in microeconomics, if you pay a person more for doing a task, she might be less willing to work on it, she might be less productive given her efforts, and she may enjoy the task less. If you start charging a fee for something, more people might start doing it. If you want your employees to save more for retirement, you may want to give them fewer investment options. If you want them to engage more in a task, you might want to offer them an additional alternative to that task. Moreover, to induce particular actions, you might have to think not only about the underlying incentives, but also about"
