The number of people killed by medical errors thing is a little controversial. People who are about to die anyway get a lot of medical interventions (which is more opportunity for errors, big small). If a patient accidentally gets an extra dose of their antacid 48 hours before they die, is it really likely that error led to their death? Because it would be counted in that 250k/yr number...
Preventable medical errors are certainly something we should continue to work to reduce (significant progress has been made over the past few decades in that regard).
I'm not advocating complacency, just pointing out that many people think the 250k/yr number is substantially inflated.
