Hospital 'never events' include silicone left in patient
A silicone object left inside someone, a patient falling from a window and the wrong person undergoing an exploratory procedure are among "never events" which have happened in Welsh hospitals.
These are "largely preventable patient safety incidents" that should not happen if proper measures are in place.
There were 60 of these incidents in Wales' seven health boards from April 2012 to present.
The Welsh Government said: "Patient safety in Wales is paramount."
Here is a timeline of the medical mistakes over the past four years.
