OAKLAND -- Kaiser Permanente hospitals have been given higher ratings as a group in 2012 than a year ago, the health care operation said Friday.
The rating determined that 31 of 33 Kaiser Permanente medical centers, or 94 percent of the group included in the report received A grades. Two others, or 6 percent, received a B.
Kaiser's rating represents an improvement over the previous rating. In the prior rating, 26 of 29 hospitals received an A grade, while three received a B.
The Leapfrog Group, a coalition of public and private purchasers of employee health coverage, rated the medical centers using its Hospital Safety Score.
The report card assigns a letter grade to hospitals based on 26 variables, including rates of infections, medication mix-ups and health care-acquired injuries.
