From: Variability of physicians’ thresholds for neuroimaging in children with recurrent headache

Belief Response Total # # (%) # (%) Fisher’s exact test
Rec NI for 1% Rec no NI for 1%
It would be possible to develop a clinical prediction rule that accurately determines risk for children with recurrent headaches. Agree 97 54 (56%) 43 (44%)  
Neutral/Disagree 17 7 (41%) 10 (59%) p = 0.302
Neuroimaging is uncomfortable for many children. Agree 66 32 (48%) 34 (52%)  
Neutral/Disagree 48 29 (60%) 19 (40%) p = 0.255
Patient comfort should be considered when making decisions about neuroimaging. Agree 63 39 (62%) 24 (38%)  
Neutral/Disagree 51 22 (43%) 29 (57%) p = 0.059
Recommending neuroimaging is likely to cause anxiety for the patient or family. Agree 70 36 (51%) 34 (49%)  
Neutral/Disagree 44 25 (57%) 19 (43%) p = 0.700
Recommending against neuroimaging is likely to cause anxiety for the patient or family. Agree 73 42 (58%) 31 (42%)  
Neutral/Disagree 41 19 (46%) 22 (54%) p = 0.328
Patient and caregiver anxiety should be considered when making decisions about neuroimaging. Agree 66 34 (52%) 32 (48%)  
Neutral/Disagree 48 27 (56%) 21 (44%) p = 0.705
The monetary cost to society should be considered when making decisions about neuroimaging. Agree 82 43 (52%) 39 (48%)  
Neutral/Disagree 32 18 (56%) 14 (44%) p = 0.835
Caregivers of patients with recurrent headaches expect me to order neuroimaging. Agree 62 37 (60%) 25 (40%)  
Neutral/Disagree 52 24 (46%) 28 (54%) p = 0.188
Patient or caregiver preferences should be considered when making decisions about neuroimaging. Agree 59 35 (59%) 24 (41%)  
Neutral/Disagree 55 26 (47%) 29 (53%) p = 0.260
A delay in diagnosis leads to significant negative consequences for physicians. Agree 95 52 (55%) 43 (45%)  
Neutral/Disagree 19 9 (47%) 10 (53%) p = 0.620
My colleagues believe it is important to avoid unnecessary neuroimaging. Agree 96 48 (50%) 48 (50%)  
Neutral/Disagree 18 5 (28%) 13 (72%) p = 0.122
I am able to convince caregivers to agree with my point of view regarding whether their child should receive neuroimaging. Agree 103 55 (53%) 48 (47%)  
Neutral/Disagree 11 6 (55%) 5 (45%) p = 1.000
I am able to determine which children require neuroimaging. Agree 108 57 (53%) 51 (47%)  
Neutral/Disagree 6 4 (67%) 2 (33%) p = 0.684
  1. Two by two tables comparing agreement with the belief with the recommendation are presented along with p-values using Fisher’s exact test (no p-values were <0.05). Rec NI for 1% group = recommended routine neuroimaging for the 1% risk group; Rec no NI for 1% group = recommended against routine neuroimaging for the 1% risk group.
