Of 1, 300 present‐on‐admission AEs (37.9 percent of total), 78.5 percent showed NCC‐MERP level F harm and 87.6 percent were "preventable/possibly preventable." Of 2, 129 hospital‐acquired AEs, 63.3 percent had level E harm, 70.8 percent were "preventable/possibly preventable"; the most common category was "surgical/procedural" (40.5 percent).
