Abstract:
Background: Blood sampling is one of the common procedures done in every ward for disease
diagnosis and prognosis. Daily hundreds of samples are collected from different wards but lack of
appropriate knowledge of blood sampling by paramedical staff and accidental errors make the
samples inappropriate for testing. Thus the need to avoid these errors for better results still
remains. We carried out this research with an aim to determine the common errors during blood
sampling; find factors responsible and propose ways to reduce these errors. Methods: A cross
sectional descriptive study was carried out at the Military and Combined Military Hospital
Rawalpindi during February and March 2014. A Venous Blood Sampling questionnaire (VBSQ)
was filled by the staff on voluntary basis in front of the researchers. The staff was briefed on the
purpose of the survey before filling the questionnaire. Sample size was 228. Results were
analysed using SPSS-21. Results: When asked in the questionnaire, around 61.6% of the
paramedical staff stated that they cleaned the vein by moving the alcohol swab from inward to
outwards while 20.8% of the staff reported that they felt the vein after disinfection. On contrary
to WHO guidelines, 89.6% identified that they had a habit of placing blood in the test tube by
holding it in the other hand, which should actually be done after inserting it into the stand.
Although 86% thought that they had ample knowledge regarding the blood sampling process but
they didn’t practice it properly. Conclusion: Pre analytical blood sampling errors are common
in our setup. Eighty six percent participants though thought that they had adequate knowledge
regarding blood sampling, but most of them were not adhering to standard protocols. There is a
need of continued education and refresher courses.
