Preventability of drug-related revisits

The random sample of 400 participants experienced a total of 522 unplanned hospital revisits during follow-up (338 hospital admissions and 184 ED visits), of which 181 (35%) were possibly drug-related visits: 128 (38%) possibly drug-related readmissions and 53 (29%) possibly drug-related ED visits (Figure 2). In total, 85 (47% of all possibly drug-related visits and 16% of all unplanned visits) visits were potentially preventable: 68 preventable drug-related readmissions (20% of all unplanned readmissions) and 17 preventable drug-related ED visits (9.4% of all unplanned ED visits).
