O-147a Assessment Of Preparation Time With Fully Liquid Versus Reconstituted Paediatric Hexavalent Vaccines. A Time And Motion Study

Abstract

<h3>Background and aims</h3> Simplified vaccine preparation steps would save time and reduce the potential of mishandlings. The aim of the study was to assess vaccine preparation time with fully liquid hexavalent vaccine (DTaP-IPV-HB-PRP-T, Sanofi Pasteur MSD, Lyon, France) versus hexavalent vaccine that needs reconstitution (DTPa-HBV-IPV/Hib, GlaxoSmithKline Biologicals, Rixensart, Belgium). <h3>Methods</h3> 96 Health Care Professionals (HCPs) participated in a randomised, cross-over, open-label, Time and Motion study in Belgium (2014). HCPs prepared each vaccine (time recorded using video equipment) in a cross-over manner with a wash-out period of 3–5 min. An independent nurse assessed preparation mishandlings by systematic review of the videos. HCPs satisfaction and preference were evaluated by a self-administered questionnaire. <h3>Results</h3> Average preparation time was 36 seconds for DTaP-IPV-HB-PRP-T versus 70.5 seconds for DTPa-HBV-IPV/Hib (p ≤ 0.001). Extrapolated yearly time savings was estimated to 664 days/year (based on 520 000 hexavalent vaccines administered per year in Belgium). On 192 preparations, 57 mishandlings occurred: 47 in the DTPa-HBV-IPV/Hib group (including one missing reconstitution of Hib component), 10 in the DTaP-IPV-HB-PRP-T group. 71.9% of HCPs were very or somewhat satisfied with ease of handling of both vaccines; 66.7% and 67.7% were very or somewhat satisfied with speed of preparation in DTaP-IPV-HB-PRP-T and DTPa-HBV-IPV/Hib groups, respectively. Almost all HCPs (97.6%) stated they would prefer the use of DTaP-IPV-HB-PRP-T vaccine in their daily practice. <h3>Conclusions</h3> Fully liquid DTaP-IPV-HB-PRP-T vaccine offers significant time gains for vaccine preparation. It has the potential to reduce mishandlings and could therefore be very useful in daily practice.
