Trigger origin for cases containing adverse events (AE)

Trigger	Triggers (n)	Triggers related to potential for harm (AE 1) (n (% (95% CI))	Triggers related to harm identified (AE 2) (n (% (95% CI))
T1: Missing, incomplete, or unclear documentation	652	35 (5.4 (3.9–7.6))	3 (0.5 (0.1–1.5))
T2: Time from initial patient contact to transfer of care exceeds accepted standards.	47	8 (17.0 (8.1–31.3))	1 (2.1 (0.1–12.7))
T3: Injury to patient or team member during patient encounter/transport	1	0 (0 (0–0))	0 (0 (0–0))
T4: Request for additional resources, personnel, or supervisor due to change in patient condition	3	0 (0 (0–0))	0 (0 (0–0))
T5: A worsening trend in patient hemodynamic or mental status indicators	7	1 (14.3 (0.7–58.0))	1 (14.3 (0.7–58.0))
T6: Cardiac arrest during transport	4	0 (0 (0–0))	1 (25.0 (1.3–78.1))
T7: Use of any of the following interventions: cardioversion, defibrillation, transcutaneous pacing, advanced airway attempt, surgical airway, intraosseous access, chest decompression, chest tube	7	1 (14.3 (0.7–58.0))	0 (0 (0–0))
T8: Failure of any intervention or procedure during patient care	9	2 (22.2 (3.9–59.8))	1 (11.1 (0.6–49.3))
T9: Use of following medications or fluids: blood products, vasopressors or inotropes, naloxone	10	1 (10 (0.5–45.9))	0 (0 (0–0))
T 10: Evidence suggestive of deviation from standard of care by performing an intervention or administering a medication that appears to be outside protocol or failure to perform an intervention or provide a medication that is within the standard of care	305	37 (12.1 (8.8–16.6))	3 (1.0 (0.3–3.1))
T 11: Medication error	24	4 (16.7 (5.5–38.2))	1 (4.2 (0.2–23.1))
