Background: Venous blood specimen collection is a common health care practice that has to follow strict guidelines, non-compliance among sampling staff may compromise patient safety. We evaluated a large-scale 2 h educational intervention that emphasised guideline adherence to assess possible improvements of venous blood specimen collection practices.
Methods: Blood specimen haemolysis is usually caused by inadequate venous blood specimen collection and handling, reflecting overall pre-analytical handling. We monitored haemolysis of serum samples with haemolysis index corresponding to ≥150 mg/L of free haemoglobin for specimens sent from 11 primary health care centres and analysed on a Vitros 5,1 clinical chemistry analyser before (2008, n=6652 samples) and after (2010, n=6121 samples) the intervention.
Results: The total percentage of haemolysed specimens was 11.8% compared to 10.5% (p=0.022) before the intervention. As groups, rural primary health care centres demonstrated a significant reduction [Odds ratios (OR)=0.744] of haemolysed specimens after intervention, whereas urban primary health care centres demonstrated a significant increase (OR=1.451) of haemolysis.
Conclusions: A large-scale 2 h educational intervention to make venous blood specimen collection staff comply with guideline practices had minor effects on collection practices. Educational interventions may be effective in wards/care centres demonstrating venous blood specimen collection practices with larger deviations from guidelines.
