Reviewing deaths in British and US hospitals: a study of two scales for assessing preventability.
Approach to Improving Safety
Setting of Care
Ascertaining whether adverse events are preventable is a continuing challenge in patient safety. Comparing two scales that assess preventability for mortality, this study found that there is high variability among experts rating the preventability of the same mortality event. These results suggest that preventability remains subjective despite attempts to define it in a reproducible fashion.
