Although positive predictive value (PPV) reports providers was high compared with other sources (54%), only 11% ADEs 6% preventable this source. PPVs ranged low 4% administrative incident 12% free-text electronic notes. Computer-generated source 31% 37% ADEs. Electronic notes 39% 29% There little overlap across sources.Our findings emphasize limitations voluntary reporting by health as principal means detection suggest are required detect geriatric patients.
