Use of ultrasound for CVC placement    
 Always 23 % (n = 15) 16 % (n = 20) 0.3
 Almost always 66 % (n = 43) 41 % (n = 51) 0.001
 Half of the time 8 % (n = 5) 22 % (n = 27) 0.03
 Almost never 2 % (n = 1) 14 % (n = 17) 0.01
 Never 2 % (n = 1) 8 % (n = 10) 0.1
Reasons you do not use ultrasound (MR)    
 You think you do not need it 28 % (n = 18) 40 % (n = 50) 0.1
 Not available 43 % (n = 28) 27 % (n = 34) 0.04

 Lack of training 5 % (n = 3) 14 % (n = 18) 0.07
 Other reasons 8 % (n = 5) 22 % (n = 28) 0.02
Which ultrasound technique do you use?    
 Skin mark 3 % (n = 2) 11 % (n = 13) 0.13
 Ultrasound guided 81 % (n = 52) 65 % (n = 74) 0.007
 Both 16 % (n = 10) 24 % (n = 27) 0.4
Which situations would encourage you to use ultrasound? (MR)    
 Obesity 57 % (n = 37) 52 % (n = 65) 0.6
 Clotting abnormalities 65 % (n = 42) 64 % (n = 80)) 0.9

 Missed landmark procedure 37 % (n = 24) 46 % (n = 57) 0.3
 None 0 5 % (n = 6)
How many times have you experienced an emergency situation in which ultrasound was not available sufficiently rapidly during the last 12 months?    
 0 40 % (n = 26) 50 % (n = 63) 0.2
 <2 35 % (n = 23) 17 % (n = 21) 0.007
 2–5 21 % (n = 14) 26 % (n = 32) 0.6
 6–10 3 % (n = 2) 6 % (n = 7) 0.7
 >10 0 2 % (n = 2)
Do you think the landmark procedure should still be taught to residents?    
 Yes 95 % (n = 62) 89 % (n = 111) 0.4
 No 5 % (n = 3) 11 % (n = 14) 0.2
