In the European Union, 300,000 newborn babies are born prematurely every year. Their care is ensured in Neonatal Intensive Care Units (NICU) where vital signs are constantly monitored. In addition, other descriptors such as motion, facial and vocal activities have been shown to be essential to assess neurobehavioral development.
In the scope of the European project Digi-NewB, we aimed to develop and evaluate a new audio-video device designed to non-invasively acquire multi-modal data (audio, video and thermal images), while fitting the wide variety of bedding environment in NICU.
Firstly, a multimodal system and associated software and guidelines to collect data in neonatal intensive care unit were proposed. Secondly, methods for post-evaluation of the acquisition phase were developed, including the study of clinician feedback and a qualitative analysis of the data.
The deployment of 19 acquisition devices in six French hospitals allowed to record more than 500 newborns of different gestational and postmenstrual ages. After the acquisition phase, clinical feedback was mostly positive. In addition, quality of more than 300 recordings was inspected and showed that 77% of the data is exploitable. In depth, the percentage of sole presence of the newborn was estimated at 62% within recordings.
This study demonstrates that audio-video acquisitions are feasible on a large scale in real life in NICU. The experience also allowed us to make a clear observation of the requirements and challenges that will have to be overcome in order to set up audio-video monitoring methods.
在欧盟，每年有 30 万新生儿早产。他们的护理由新生儿重症监护病房（NICU）提供，在那里生命体征被持续监测。此外，其他描述符，如运动、面部和声音活动，已被证明对评估神经行为发育至关重要。
在欧洲项目 Digi-NewB 的范围内，我们旨在开发和评估一种新的音视频设备，旨在非侵入性地获取多模态数据（音频、视频和热图像），同时适应 NICU 中各种不同的床位环境。
首先，提出了一种多模态系统及相关软件和指南，用于在新生儿重症监护病房中采集数据。其次，开发了用于采集后评估的方法，包括对临床医生反馈的研究和对数据的定性分析。
在六家法国医院部署了 19 个采集设备，记录了 500 多名不同胎龄和月经龄的新生儿。采集阶段后，临床反馈大多是积极的。此外，检查了超过 300 个录音的质量，结果表明 77%的数据是可利用的。深入分析表明，在记录中，新生儿单独出现的比例估计为 62%。
这项研究表明，在 NICU 的实际生活中，音视频采集是可行的。这一经验还使我们清楚地观察到，为了建立音视频监测方法，还需要克服哪些要求和挑战。
