Rationale of trigger modifications from previous work24
| Trigger characteristics | Previous trigger | New trigger | Rationale |
| Time period | 10 days | 14 days | Previous findings showed that diagnostic errors continued to be discovered at the 10-day cut-off |
| Inclusion criteria | Did not account for planned hospitalisations or elective surgeries | Electronically excludes planned or elective admissions related to (or from) day surgery, scheduled ambulatory admit, preoperative clinics, cardiology invasive procedure clinic | Lower proportion of triggered false positives will increase PPV as well as efficiency of record reviews |
| Did not account for admissions to units considered ‘non-acute’ | Electronically excludes admissions to long term and intermediate care, and rehabilitation units | ||
| Included all hospitalisations | Includes only hospitalisations electronically designated as ‘acute care’ (eg, acute medicine, acute surgery, acute mental health) |
PPV, positive predictive value.
