Such a strong statement, the patients dying due to charting errors, crys for a source. As does the fact that the NHS is not among the better systems, because any statistic, spending, outcome, average life span of people, shows the various single payer systems (in order to group all state sponsored systems together even if their are differences) out perform the US one.

Let's entertain so that charting errors cause patient deaths. In order to judge how the NHS performs relative to other systems would require statistics on that fact alone. Not sure those even exist.
