The objective of this pilot study was to assess the acceptability and feasibility of using BrightHearts, a biofeedback-assisted relaxation application (app), in children undergoing painful procedures.
Thirty children 7 to 18 years of age undergoing a medical procedure (peripheral blood collection, botulinum toxin injection, or intravenous cannula insertion) participated. Participants used BrightHearts, a heart rate-controlled biofeedback-assisted relaxation training app delivered via an iPad with heart rate measured through a pulse oximeter worn on the ear or thumb. Feasibility was assessed through observations and patient, parent/carer, and healthcare professional feedback. Patient, parent/carer, and healthcare professional satisfaction with BrightHearts was rated using investigator-developed surveys.
Eighty-three percent of child participants reported that they found BrightHearts helpful during the procedure and that they would use BrightHearts again. All parents and 96% of healthcare professionals indicated they would use BrightHearts again. Sixty-four percent of healthcare providers perceived that BrightHearts assisted with the ease of performing the procedure. Qualitative analyses found 2 themes: (1) BrightHearts calms through providing distraction and biofeedback and (2) the impact of BrightHearts on the procedure.
This pilot study demonstrates the feasibility of using biofeedback-assisted relaxation delivered via the BrightHearts app in children undergoing peripheral blood collection and cannulation. Future studies are required to evaluate BrightHearts' efficacy in reducing pain and anxiety during painful procedures and distinguish the effects of a biofeedback-mediated app from distraction.
本试点研究的目的是评估在接受痛苦治疗的儿童中使用BrightHearts（一种生物反馈辅助放松应用程序）的可接受性和可行性。
30名7至18岁正在接受医疗程序（外周血采集、肉毒杆菌毒素注射或静脉插管）的儿童参与了研究。参与者使用BrightHearts，这是一款通过iPad提供的心率控制生物反馈辅助放松训练应用程序，通过佩戴在耳朵或拇指上的脉搏血氧仪测量心率。通过观察以及患者、家长/照顾者和医护人员的反馈来评估可行性。使用研究者开发的调查问卷对患者、家长/照顾者和医护人员对BrightHearts的满意度进行评分。
83%的儿童参与者报告称他们发现在治疗过程中BrightHearts很有帮助，并且他们会再次使用BrightHearts。所有家长和96%的医护人员表示他们会再次使用BrightHearts。64%的医护人员认为BrightHearts有助于轻松完成治疗程序。定性分析发现了两个主题：（1）BrightHearts通过提供分散注意力和生物反馈来使人平静；（2）BrightHearts对治疗程序的影响。
这项试点研究证明了在接受外周血采集和插管的儿童中使用通过BrightHearts应用程序提供的生物反馈辅助放松的可行性。未来需要进行研究，以评估BrightHearts在减轻痛苦治疗过程中的疼痛和焦虑方面的疗效，并区分生物反馈介导的应用程序与分散注意力的效果。
