Two errors occurred in the ORIGINAL CONTRIBUTION entitled "Evaluating Individual Hospital Quality Through Outcome Statistics," published in the May 23/30 issue of THE JOURNAL (1986;255:2780-2784). On page 2782, the first sentence in the third full paragraph in column 1 should have read as follows: "In contrast, none [not 'one'] of the very-low-volume hospitals exhibited better than expected performance at usual levels of statistical significance." On page 2784, the last sentence in the first full paragraph in column 1 should have read as follows: "If only five deaths are observed, even though the calculated death rate of 25% [not '20%'] is substantially above the expected rate of 15%, it is not statistically significant."
