(40 % response rate)
Post-test = 47 (31 % RR total; 79.7 % pretest)
Quantitative
Survey: Pre and post education
Findings reported from midwifery participants only.
Overall: Enthusiasm for cord blood collection;
Concerns regarding staffing as a potential problem.
Posttest: useful education with improved knowledge of conditions that could benefit from public CB bank

*66 % (n = 39) aware additional uses: autoimmune, genetic and degenerative diseases/conditions.
*44 % (n = 26) wanted more information.
*Of 23 who had CB collection experience (39 %), 14/23 (86 %) had performed cord blood collection without prior training.
Attitudes
*Positive responses to program good to fantastic (55, 93 %)
*4 (6.7 %) midwives expressed concerns regarding extra paperwork associated with cord blood donation/collection.
*Posttest:
Knowledge
*Training sessions useful in understanding whole process (29, 62 %) rationale to collect (9, 19 %) and some practical details (9,19 %).

Community midwives (n = 10)
Hospital midwives (n = 10)
Obstetricians (n = 10)
Pregnant women, future parents and donors (n = 30)
Mixed methods using participatory approach with establishment of a taskforce and public multidisciplinary round table
Focus groups; (maximum 10 participants, led by 2 psychologists)
Survey: Anonymous self -administered
(Demographic, knowledge, opinion items)
Findings reported from midwives and obstetrician/gynaecologists only.
Overall: Support for altruistic cord blood donation; Better health professional education needed.
Focus Group Themes:
*Hospital & community midwives recognised social/moral value of CB donation Vs no social/moral value recognition by obstetricians
*100 % hospital midwives expressed a negative moral assessment of private cord blood banking
*Midwives viewed obstetricians as providing crucial role in providing parents with information
*All disciplines agreed obstetricians can promote CB donation through providing accurate information to expectant parents.
*Specific education and HP support roles needed to promote donation
Questionnaire
*Obstetricians (30, 94 %) & midwives (28, 87.5 %) were preferred providers of information to parents
*Information should be provided in prenatal courses (24, 75 %)
*Altruistic (25, 78 %) and moral duty (7,22 %) were factors in supporting public donation
Outcome: Development of information brochure
Few knowledge questions; most opinion based.
Small sample sizes allowed for limited between group comparisons
Researchers developed own assessment tool, nil validity or reliability testing reported

Questionnaire (n = 38)
Semi-structured interviews
(n = 8)
Qualitative/Mixed methods
Survey: Self-administered
Semi-structured interviews
Overall: Obstetricians generally willing to participate in cord blood collection.
Status of CB collection
* 60.5 % indicated there was no CB collection training course at their institution.
* 28.9 % believed that CB collection training is necessary prior to collecting CB.
68.4 % believed that CB collection in addition to their routine care did not place a burden on them.
* 84.2 % believed that CB collection did not pose a risk prior to or following delivery.
Training courses
* 6 respondents answered that if CB is simply collected, a training course is not mandatory. However, a training course prior to collecting CB would assist to collect greater volumes and prevent bacterial contamination.
Burden and risks associated with CB collection
*All respondents agreed that there were no risks or burdens as CB collection is stopped if anything goes wrong at the time.
Small sample of a large number of obstetricians in the 53 hospital settings.
Results represent obstetricians’ beliefs and opinions, not knowledge.

Focus Group: 8 midwives
Overall: 3 key themes identified as Negotiating space; Negotiating access and Negotiating priorities and practices.
Acknowledgement of midwives as gatekeepers in access to umbilical cord blood: themes of power, authority and control.
Results highlighted:
*Midwives were perceived as regarding privately employed phlebotomists/CB collectors as external to woman’s care team
*Perception that midwifery practice is prioritised over request for cord blood collection as it benefits maternal and infant health and wellbeing, while CB collection seen as a non-essential ‘option’ or ‘wish’ than can alter ‘important’ midwifery practice.
*Perception that Midwives rank CB collection for private banking as a low priority.
*In contrast, Perception of pregnant women that midwives are in a less powerful role than pregnant women relating to UCB collection (i.e. women’s wishes are the priority), supported by midwifery responses.
Member checking in interpretation of qualitative data was not reported; limits content validity relating to interpretation of midwifery roles and priorities.
