Capillary self-blood collection (SBC) with mailed samples enables remote laboratory monitoring without in-person healthcare visits. This approach may improve continuity of care for patients, especially with chronic conditions.
Compare pain perception between venous blood draws and capillary SBC and evaluate the usability and blood volume yield of SBC devices.
In this cross-sectional study, general practice patients from mid of Germany, Germany performed SBC using the Tasso+ upper-arm device and mailed samples to a laboratory. Pain, usability, SBC volume, and associated factors were analysed using bivariate and general linear models.
Of 106 patients, 57.5% performed SBC without assistance. Self-perceived pain was lower among SBC draws (0.13, SD = 0.42) versus venous draws (1.21, SD = 1.60) ( < .001). 59.4% self-collected ≥130 μL blood plasma. Patient characteristics were not associated with SBC volume in regression analysis. Overall, the mean System Usability Scale (SUS) score was 86.2, indicating high usability. Lower school education was associated with lower usability scores, while lower fear of blood and needles were associated with higher usability scores in regression analysis.
Capillary SBC had high feasibility and usability and caused less pain than venous draws in the general practice setting. SBC shows promises for enabling remote laboratory monitoring.
通过邮寄样本进行毛细血管自我采血（SBC）可实现远程实验室监测，无需患者亲自到医疗机构就诊。这种方法可能会改善患者的护理连续性，尤其是对于患有慢性病的患者。
比较静脉采血和毛细血管SBC之间的疼痛感知，并评估SBC设备的易用性和采血量。
在这项横断面研究中，来自德国中部的全科患者使用Tasso+上臂设备进行SBC，并将样本邮寄至实验室。使用双变量和一般线性模型分析疼痛、易用性、SBC血量及相关因素。
106名患者中，57.5%的患者在无协助的情况下进行了SBC。与静脉采血（1.21，标准差=1.60）相比，SBC采血时的自我感知疼痛较低（0.13，标准差=0.42）（P<0.001）。59.4%的患者自行采集了≥130μL血浆。在回归分析中，患者特征与SBC血量无关。总体而言，系统易用性量表（SUS）的平均得分为86.2，表明易用性较高。在回归分析中，受教育程度较低与易用性得分较低相关，而对血液和针头的恐惧较低与易用性得分较高相关。
在全科医疗环境中，毛细血管SBC具有较高的可行性和易用性，且比静脉采血引起的疼痛更少。SBC有望实现远程实验室监测。
