I want to clarify this point because I think it is misleading.
Empirical research is very important in economics. The issue is that it is really hard to get empirical evidence to "tell the truth" while it is pretty easy to get empirical evidence to tell one what he wants to hear. The phrase "If you torture the data long enough, it will confess" is quite apropos in the field.
Because of some serious constraints regarding empiricism in economics, what economists try to do (for the most part) is use well-established models or innovate on them in creative ways that seem theoretically sound. Then they inform those models with data and see what happens. Sometimes some empirical trends arise when this is done many times in a variety of relevant situations.
Regarding the European healthcare systems that are claimed to have proven to be effective, the criticisms from economic models upon those systems are not about whether or not they are effective, and the data don't comment on "effectiveness" that much either. The data do, however, reveal what the economic criticisms have to say. The criticisms are that the European systems, regardless of "effectiveness", suffer from some specific problems predicted by economic theory. The basic form of those problems are quantity, quality, and innovation are lower than they could be and costs are higher than they could be. The data suggest this and fit the theory. Some examples of this are the significant amount of rationing in those systems, how patients that have the opportunity receive better care outside of the systems, and how taxes to pay for the systems are high and increasing. These systems are not that old (have not shown much antifragility) and they have significant problems that economic theory predicts that the data strongly suggest they have.
