FREE CASE EVALUATION 
About Adam Peck About one in three people in the United States will encounter some kind of mistake during a hospital stay, U.S. researchers said Thursday.
The finding, which is based on a new tool for measuring hospital errors, is about 10 times higher than estimates using older methods, suggesting much work remains in efforts to improve health quality.
Medical errors can range from bedsores to objects left in the body after surgery to life-threatening staph infections.
To find the best yardstick, the team tested three methods of tracking errors on the same set of medical records from three different hospitals.
Among the 795 patient records reviewed, voluntary reporting detected four problems, the Agency for Healthcare Research’s quality indicator found 35, and the Institute for Healthcare Improvement’s tool detected 354 events — 10 times more than AHR’s method.
Hospitals, it is reported, fail to detect more than 90% of the adverse events that occur among hospitalized patients. The findings suggest there may be many errors that go undetected.
Based upon insurance claims to estimate the annual cost of medical errors that harm patients to be $17.1 billion in 2008 dollars.
They found that 10 types of errors accounted for more than two-thirds of the total cost, with the most common ones being pressure ulcers or bedsores, postoperative infections and persistent back pain following back surgery. The researchers recommended that those three types of errors receive top priority for intervention and improvement.
