  • We can conclude that the RI electronic witness system accurately records all witness steps and reduces the workload and pressure that manual witness created when it was introduced. It identified in our lab a low true mismatch rate that compares favourably with other studies already published, like the one that studied wristband mix-ups in an American Hospital setting, that reported an error rate of 0.1%. In our series, all true mismatches were rectified in under 10 seconds In the future we aim to expand the study with data from other centres in order to corroborate our data. With these data we aim to estimate what the likely incidence of mix-ups in IVF laboratories may be worldwide. We all make mistakes...

    7. 7. Viability assessment by birefringence imaging with polarization microscopy Spindle imaging of the MII oocyte De Santis et al., RBM Online 2005 During meiosis and fertilization meiotic spindles are responsible for proper segregation of the nuclear material, and abnormalities in this fragile structure can lead to infertility, miscarriage and genetic diseases, such as Down syndrome
    8. 8. Why are results contradictory? • The dynamics of spindle formation during oocyte maturation were not considered 1. Spindle visualization might change within the maturation stages: MI-1st.PB extrutiontelaphase I (MS dissapear for 40-60 minutes!!)- MII 2. The microtubules of the MS are highly sensitive to chemical (hyaluronidase), and physical changes ( temperature& pH variations) that may occur during oocyte handling. Shift of the PB1 position may also be related to physical displacement during denudation. • A precise classification spindle imaging should be performed repeatedly: after hyaluronidase treatment and immediately prior to ICSI Rienzi et al., RBM Online 2005 Montag et al.,RBM Online 2006
    9. 9. Oocyte zona birefringence intensity High zona birefringence Low zona birefringence Montag et al.,RBM Online 2008 undetectable Ebner-Balaban F&S 2010 Polarization microscopy allows the distinction of three layers within the ZP. Inner layer exhibits the highest birefringence(Pelletier 2004). Zona birefringence intensity is higher in conception cycles(Shen 2005) The multilaminar structure of the ZP revealed by polarization microscopy is directly linked to the paracrystalline network structure of the zona which is formed during the follicular maturation by the oocyte. So a high birefringence of the inner zona layer might indicate an optimal formation of the ordered structure during oocyte maturation. HZB oocytes can have better conditions during follicular growth and maturation compared with a LZB oocyte with unordered zona structure. Regular structural integrity of ZP may reflect an optimal cytoplasmic potential of an oocyte and its various cellular and molecular structures

    11. 11. Time-lapse imaging; morphokinetics • One of the fundamental problems of the current embryo quality assessment by morphology is the static evaluation of a highly dynamic developing entity. Current systems analyze the morphology at a few predefined time points during embryo development preimplantation, with the consequent lack of information about what happened between the analyzed points. Thus continual monitoring might provide one strategy to collect a complete picture of embryo developmental kinetics and improve the success rate of viable embryo selection • So far 2 algorithm have been proposed for morphokinetic embryo selection to improve success rates based on parameters derived from time-lapse measurements ** Wong Nat Biotechnology 2010; Analyzed time-lapse image series of embryo development to identify predictive markers of blastocyst development and the underlying gene expression profile (arrested /normal developing) Sample was composed of supernumerary embryos cryopreserved at the 2PN stage and donated to research. None of the embryos were transferred. No data on IR were obtained. Hierarchy of morphokinetic markers were not used for decision making ** Meseguer HR 2010, F&S 2012

MSOME: Motile sperm organelle morphology examination IMSI: Intracytoplasmic morphologically selected sperm injection Selection of the motile spermatozoa with normal nucleus at 6300X objective Elimination of the sperm cells with vacuoles within the nucleus Bartoov 2001,2002,2003; Berkovitz 2005 Bartoov et al.,HR 2006 IMSI range: X6000-X12.500
    15. 15. **Selected group of male factor infertility Significantly improved CPR & IR, Significantly reduced miscarriage rates Vanderzwalmen 2008 had shown that only sperm with ≥1 or large vacuoles with other head abnormalities do effect embryo development.

We think it is low...but we don’t know
    19. 19. Mandatory guidelines of medicalscientific societies • ESHRE, FLASEF(Latin America), HFEA mandates in their guidelines and codes of practice the permanent labeling of all labware to identify the source of the biological material inside the tube or dish, and the application of witnessing protocols to double check the identification of samples and the patients or donors whom they relate, at all aforementioned critical points of the clinical and lab. procedures
    20. 20. Witnessing protocols should be followed when any of the following clinical or laboratory procedures take place: • Collecting eggs • Collecting sperm • Preparing sperm • Mixing sperm and eggs or injecting sperm into eggs • Transferring gametes or embryos between tubes or dishes • Transferring embryos into a woman • Inseminating a woman with sperm prepared in the laboratory • Placing gametes or embryos into cryopreservation • Removing gametes or embryos from cryopreservation • Disposing of gametes or embryos • Transporting gametes or embryos **Inclusion of novel technologies

    32. 32. Implementing an electronic witnessing system into a busy IVF clinic – one clinic’s experience. Sanges, et al.,Genera Center for Reproductive Medicine, Rome, Italy ESHRE 2013 London , Poster presentation Study question: The aim of the study was to evaluate the time required to install an ex-novo electronic witnessing system (RI Witness™) into a busy IVF clinic. Participants/materials, setting, methods: The simultaneous presence of two different patient samples in the working area was defined as “true mismatches”, whilst mismatches derived from acceptable common errors were defined as “secondary mismatches”. Finally, we estimated the level of satisfaction to laboratory staff (5= very,4= fair,3= adequate,2= poor, 1= not at all). Main results and the role of chance: The installation and integration of the system required about 4 working days whilst the training of all the laboratory staff was carried out the week after. The validation period took one month and a total of 2099 witnessing steps were carried out. During this period, a total of 17 mismatches (0.81%) were recorded, 2 of which were true human errors (0.09%) and required additional intervention. During the post-validation period, a total of 5921 witnessing steps we carried out with 852 patients. The total mismatch rate was 0.66%(39/5921). Excluding secondary errors, we recorded a true human error rate equal to 0.10%(6/5921). Errors due to system configuration were recorded during and after the validation period (0.47 and 0.05, respectively). The user satisfaction index was 4.8. Summary answer: The integration of the RI Witness™ system in the daily routine is simple, fast and safeguards the reliability of the entire IVF process. Wider implications of the findings : Our experience suggests that the integration of RI Witness™ in the daily routine is simple and fast and allows for an improvement in system usage after a short time. RI Witness™recorded a constant true human error rate that is within the acceptability range. Moreover, the warning of mismatches permits immediate corrective intervention, safeguarding the reliability of the entire IVF process. Other benefits include the traceability of each step performed and a reduction of staff workload and distractions, thus increasing operator satisfaction.
