what makes these better? they are costly and assumed better built as they may have to keep someone alive but what is better? components? design standards?

Components have higher reliability and tighter tolerances, and the design standards take EMI protection beyond its limits. Hence the overall product reliability is much higher than consumer grade products. Plus all of these of course also  increase the cost of design and development time.

Leakage current is often a factor..... in a medical environment it is probably more important to have very low touch currents.

with medical power supplies you are also paying for the liability fees, in case a hospital decides to sue a manufacturer.

Same reasoning with "medical grade" wall outlets. A manufacturer's rep said the extra cost is for their CYA fund.
