Understanding donor perception of the blood donation experience is central to maintaining an adequate blood supply. Studies that use questionnaires to assess barriers/facilitators to donation may be influenced by response bias. To address this, we conducted an innovative study integrating quantitative informatic techniques with qualitative data analysis of YouTube video content to explore donor experiences and barriers and facilitators to whole blood donation.
Sampling of YouTube videos was conducted using search parameters for identifying relevant videos, based on donors' language used to describe their whole blood donation experiences (e.g., blood donation, blood donor, donated blood, gave/give blood). We eliminated duplicate videos; filtered out non-English videos, those made outside the United States, and those with no transcripts; and restricted the time period during which videos were posted from 2015 to 2019. Search parameters were fed into a Python script, which downloaded video transcripts for all search results. The final sample was 102 noncommercial and 34 commercial transcripts. The subsequent transcriptions were uploaded into qualitative analysis software and coded two coders. A third coder randomly selected transcripts to review to ensure consistency.
Barriers to whole blood donation include having prior negative experiences with donation and donation-related fear. Facilitators included altruism, having a personal connection to donation, donation center incentives, and positive experiences with blood center staff.
Themes identified in this study were similar to those in the existing literature. This suggests that current questionnaires to address barriers/facilitators to donation are unlikely to be meaningfully impacted by response bias.
了解供者对献血体验的看法对于维持充足的血液供应至关重要。使用问卷评估献血障碍/促进因素的研究可能受到反应偏差的影响。为了解决这个问题,我们进行了一项创新性研究,将定量信息学技术与对 YouTube 视频内容的定性数据分析相结合,以探索供者的献血体验以及献血的障碍和促进因素。
使用基于供者用于描述其全血献血体验的语言(例如,献血、献血者、捐献的血液、给予/献血)的搜索参数来进行 YouTube 视频的抽样。我们消除了重复的视频;筛选掉非英语视频、非美国制作的视频以及没有字幕的视频;并限制了视频发布的时间段为 2015 年至 2019 年。搜索参数被输入到一个 Python 脚本中,该脚本下载了所有搜索结果的视频字幕。最终的样本包括 102 个非商业性和 34 个商业性字幕。随后将转录内容上传到定性分析软件中,并由两位编码员进行编码。第三位编码员随机选择转录内容进行审核,以确保一致性。
全血献血的障碍包括先前有过负面的献血经历和与献血相关的恐惧。促进因素包括利他主义、与献血有个人联系、献血中心的激励措施以及与血液中心工作人员的积极体验。
本研究中确定的主题与现有文献中的主题相似。这表明,目前用于解决献血障碍/促进因素的问卷不太可能受到反应偏差的显著影响。
