A score of 2 or more suggested that over half might have been prevented.
By far the largest category of problematic incidents involved an unplanned admission or readmission as a result of previous treatment at the hospital.
Injuries sustained while in hospital, such as falls, burns, or pressure sores, and other complications, such as a heart attack or deep vein thrombosis were the next most common categories.
One in seven incidents (15%) were sufficient to interfere with daily life or cause temporary disability for six months or more.
One in 10 caused permanent disability and a further one in 10 contributed to the patients death.
In the light of the findings from this study and [previous UK research], it is now clear that 8 to 10% of patients in NHS hospitals may experience some kind of adverse events, say the authors.
..between 30% and 55% are to some extent preventable, they add.
