We stipulate they should have a VTE risk assessment within 24 hours of admission, we don't use the 14 hours as we didn't think it feasible to achieve. This may change now NICE have introduced their tweaks to the guidance which puts us under more pressure to achieve the 14 hour target and the 12 hour target for patients in ED.
I think we are outliers still using the 24 target for VTE risk assessment.
