METHODS: We conducted semi-structured interviews containing open-ended questions with 12 feasibility study participants recruited by purposive sampling. All interviews were audio-recorded with verbatim transcription. Thematic data analysis was performed at the latent level by using an inductive approach with a previously published 6-phase guide.
RESULTS: Three key themes emerged: (1) perceived value of the intervention in clinical practice, (2) challenges and barriers to implementation of the intervention, and (3) suggestions forthe development of the intervention. Due to functional limitations and lack of research, medical professional participants revealed clinical equipoise regarding the utility of implantable Doppler probes. However,the device was well received by patient participants. Challenges included device training needs for medical professionals and educational sessions for patients. Innovative ideas for development included the insertion of a display screen, adopting disposable units to reduce overall cost, online access allowing remote monitoring, decreasing external monitoring unit size, and integrating a wireless connection with the probe to reduce signal errors and increase patient safety.
CONCLUSIONS: The clinical need for blood flow sensing technology in kidney transplants has been widely acknowledged. Implantable Doppler probes may be a beneficial adjunct in the early postoperative surveillance of kidney transplant patients. However, the device\'s technical limitations are the main challenges to its acceptance in clinical practice.
方法:我们对12名通过目的抽样招募的可行性研究参与者进行了包含开放式问题的半结构化访谈。所有访谈都是用逐字转录录音。通过使用归纳方法和先前发布的6相指南,在潜在水平上进行了主题数据分析。
结果:出现了三个关键主题:(1)临床实践中干预措施的感知价值,(2)实施干预的挑战和障碍,(3)干预措施发展的建议。由于功能限制和缺乏研究,医学专业参与者揭示了关于可植入多普勒探头的实用性的临床平衡。然而,该装置受到患者参与者的欢迎。挑战包括医疗专业人员的设备培训需求和患者的教育课程。创新的发展理念包括插入显示屏,采用一次性单元以降低总成本,允许远程监控的在线访问,减小外部监控单元的大小,并将无线连接与探头集成,以减少信号错误并提高患者安全性。
结论:在肾移植中对血流传感技术的临床需求已得到广泛认可。植入式多普勒探头可能是肾移植患者术后早期监测的有益辅助手段。然而,该装置的技术局限性是其在临床实践中被接受的主要挑战。
