Abstract

Objective: To evaluate whether patients are capable and willing to self-administer and interpret an EldonCard test to determine their Rh status.

Methods: This was a cross-sectional study in Honolulu, HI, USA of pregnancy-capable people aged 14-50 years who did not know their blood type and had never used an EldonCard. Participants independently completed EldonCard testing, determined their Rh type and answered a survey on feasibility and acceptability. Separately, a blinded clinician recorded their interpretation of the participant's EldonCard. When available, we obtained blood type from the electronic health record (EHR). We measured Rh type agreement between participant, clinician and EHR, as well as participant comfort and acceptability of testing.

Results: Of the 330 total participants, 288 (87.3%) completed testing. Patients and clinicians had 94.0% agreement in their interpretation of the EldonCard for Rh status. Patient interpretation had 83.5% agreement with EHR while clinician and EHR had 92.3% agreement. Sensitivity of EldonCard interpretation by patient and clinician was 100%. Specificity was 83.2% for patients and 92.2% for clinicians. Two patients (of 117) had Rh-negative blood type in the EHR. The vast majority of participants found the EldonCard testing easy (94.4%) and felt comfortable doing the testing (93.7%). Participants with lower education levels felt less confident (p=0.003) and less comfortable with testing (p=0.038); however, their ability to interpret results was similar to others (p=0.051).

Conclusions: Patient-performed Rh typing via the EldonCard is an effective and acceptable option for patients, and could be used as a primary screening test for Rh status.

自行进行的 Rh 分型:一项横断面研究。
目的评估患者是否有能力和意愿自行操作和解释 EldonCard 测试,以确定其 Rh 状态:这是一项在美国夏威夷州檀香山市进行的横断面研究,研究对象是年龄在14-50岁之间、不知道自己血型且从未使用过EldonCard的有怀孕能力的人。参与者独立完成了 EldonCard 测试,确定了自己的 Rh 血型,并回答了关于可行性和可接受性的调查。另外,一名盲人临床医生记录了他们对参与者的埃尔登卡的解释。如果有的话,我们会从电子健康记录(EHR)中获取血型。我们测量了参与者、临床医生和 EHR 之间的 Rh 血型一致性,以及参与者对测试的舒适度和接受度:在总共 330 名参与者中,288 人(87.3%)完成了检测。患者和临床医生对 EldonCard 的 Rh 状态解释有 94.0% 的一致性。患者的解释与电子病历的一致性为 83.5%,而临床医生与电子病历的一致性为 92.3%。患者和临床医生对 EldonCard 解释的灵敏度为 100%。患者的特异性为 83.2%,临床医生的特异性为 92.2%。有两名患者(共 117 人)的 EHR 血型为 Rh 阴性。绝大多数参与者认为 EldonCard 测试很简单(94.4%),并且在测试过程中感觉很舒服(93.7%)。受教育程度较低的参与者对测试的信心不足(p=0.003),感觉不太舒服(p=0.038);但他们解释结果的能力与其他人相似(p=0.051):结论:通过 EldonCard 由患者进行 Rh 分型是一种有效且可接受的选择,可用作 Rh 状态的初筛检测。
