TABLE 3.

Agreement Response of Participants With Hands-on Experience (n = 204)* and No Hands-on Experience (n = 132)* With Syringe Brake

	Survey Statements	Agree, n (%)		aOR (95% CI)	P
		Hands-on	No Hands-on
	Ease of use
1	It is easy to fit Syringe Brake onto the syringe.	171 (86.4)	79 (60.3)	4.36 (2.53–7.53)	<0.001
2	It is easy to set the desired volume to be administered.	191 (94.1)	92 (70.8)	7.25 (3.55–14.81)	<0.001
3	It is difficult to learn how to use Syringe Brake. (reverse)	178 (88.1)	80 (61.1)	4.97 (2.83–8.72)	<0.001
	Safety aspects
4	Syringe Brake allows the drug to be titrated safely.	186 (91.6)	96 (72.7)	4.22 (2.24–7.96)	<0.001
5	Syringe Brake gives users the confidence to avoid overdosing patient.	179 (88.2)	90 (68.7)	3.38 (1.92–5.95)	<0.001
6	Using Syringe Brake can prevent medication error when the user does not realize diluted morphine (10 mg/10 mL) 1 mg equates 1 mL.	171 (83.8)	95 (72.0)	2.03 (1.19–3.46)	0.010
7	Syringe Brake can prevent wrong dose administration arising from miscommunication when the drug is prepared and administered by a different person.	154 (75.5)	87 (65.9)	1.58 (0.98–2.57)	0.062
	Efficiency
8	For a process that requires excess dose to be discarded before administration, for example, discards 9 mL when only 1 mg is required, Syringe Brake saves time by removing the necessity to discard excess morphine.	139 (68.8)	76 (58.0)	1.65 (1.03–2.65)	0.037
	Acceptance
9	I am willing to use Syringe Brake.	169 (83.3)	85 (64.9)	2.72 (1.62–4.58)	<0.001
10	I prefer using Syringe Brake compared with the previous workflow.	134 (66.3)	74 (56.1)	1.60 (1.01–2.52)	0.046
11	Overall, I am satisfied with the use of Syringe Brake to prevent medication error.	174 (86.1)	80 (61.1)	4.04 (2.36–6.92)	<0.001
