go to box 2c Separate columns occur in the WIESNZ18 weights table for episodes that are: sameday one day multiday low outliers multiday inliers high outliers. The base WIES score for sameday episodes (inlier and low outlier), one day episodes (inlier and low outliers), and multiday inliers can be read directly from the WIESNZ18 weights table using the appropriate column and row (NZdrg70). The base WIES score for multiday low outliers can be calculated by multiplying the length of stay less one day, by the per diem weight given in the WIESNZ18 patient’s weights table and adding the one day inlier weight (from table). The base WIES score for high outliers is obtained by multiplying the number of high outlier days by the high outlier per diem weight (from table) and adding the multiday inlier weight (from table).
