Participating VBS personnel had to read the national
VBS guideline as a part of the educational interven-
tion program and intervention group signify that
they had read the guidelines before the education. 2)
Attendance at two oral lectures as compulsory. The
first included VBS practices concerning informa-
tion regarding local non-adherence to preanalytical
practices, and emphasis was also put on how to avoid
haemolysis.
Results
A validated venous blood sampling questionnaire
The venous blood sampling questionnaire was found
to have acceptable validity and reliability. It included
19 questions of which 9 had in total 34 underlying
items. The test-retest analysis demonstrated that
questions and items had acceptable stability; a total
of 82% fulfilled the reliability acceptance criteria.
Questions and items were considered clearly outlined
and easy to understand (19).
Adherence to venous blood sampling guidelines
When evaluating the educational intervention pro-
gram, we found that self-reported adherence to guide-
lines had significantly improved in several items (10
out of 32) in the intervention group, while the control
group showed no significant improvements at all.
Intervention group participants reported more
often searching for information using the Internet
and internal networks. They more seldom used prin-
ted papers, and seldom asked colleagues for informa-
tion (
p
< 0.001-0.003). Participants also reported that
they more often allowed the patients to rest for the
recommended time before venipuncture (
p
= 0.004).
After the educational intervention program, parti-
cipants from the intervention group stated that they
more often checked that the test request and test tube
identification number matched (
p
= 0.003), and more
often labelled test tubes at the patient’s side before
specimen collection (
p
= <0.001) in accordance with
guidelines. They also significantly improved control
