Table 1 Initial code list for analysis of event report text.

Domain Code Definition
I Who: Who was/were the ameliorator/s (can code multiple, if needed) 1: Patient/Patient‐Related Patient, family member, patient representative
2: Clinician Physician, physician's assistant, nurse practitioner
3: Nurse RN, MA, LPN
4: Office staff Front office staff, billing, administration, or medical records
5: Lab or lab personnel Laboratory technician
6: Pharmacy or pharmacist Pharmacist, pharmacy technician
7: Radiology/radiology tech Radiologists, radiology technician
8: Other Any other person not in the above categories
II What: (a) Was the amelioration expected, typical action; OR unexpected above and beyond. If patient was the ameliorator, no code needed. A: Most people, most times Most people, most of the time would take this action; it would be expected for most people to do this under the event circumstances.
B: Over and above The action taken is exceptional and goes above and beyond what would normally expect (“Wow! I didn't expect that”)
C: Insufficient information Use to indicate there seems to be insufficient information to code the event in this domain.
III What: (b) What exactly did the ameliorator do (eg, phone call, double‐check, asked questions, etc) [open code or in vivo code] Descriptive codes to get a sense of types of things people do when they ameliorate (eg, phone call, asked extra questions, double‐checked, actually followed protocol)
IV When: At what point in the process (ie, the entire loop for an event procedure or activity) did the amelioration occur? PRE Amelioration took place before event process started (eg, system change to prevent a future error; corrected medical record to prevent future error)
EARLY Amelioration took place early in the event process (eg, MD noticed wrote wrong dose on Rx and corrected before patient left)
MID Amelioration took place in middle of process (eg, pharmacy noticed dose was wrong, clarified with clinic, then dispensed correctly)
LATE Amelioration took place late in event process (eg, patient noticed that dispense pills were different and clarified before taking)
V. System change? SYSTEM Use to indicate a change made to system or protocol or practice (ie, implemented an office‐wide change), either as a part of the amelioration or as a result of the event
