导读：据报道，在医疗保健专业人员中，压力和倦怠的患病率很高；然而，目前用于量化这些指标的工具不符合医生忙碌的生活方式，更不符合感染预防政策。鉴于压力的增加可能会影响医疗保健专业人员和护理中的患者，本研究旨在评估可穿戴生物传感器监测和管理医疗保健专业人员所经历的压力的有效性。方法：12名健康男性志愿者完成了一项旨在以分级方式诱导生理应激的增量运动方案。可穿戴消费级生物传感器（Vital Scout, VivaLNK, Inc.）用于测量整个运动过程中的压力、能量消耗、呼吸率和活动。这些变量通过在线呼吸分析（MedGraphics Ultima Series）进行验证。结果：与在线“金标准”测量相比，Vital Scout生物传感器在测量能量消耗（r = .776, p < .001）和呼吸速率（r = .744, p < .001）方面表现出高水平的准确性。在增量运动试验中观察到的(V) over dotO(2)增加与Vital Scout生物传感器测量的活动有关（r = .777, p < .001）。相比之下，(V) / dotO(2)的变化与Vital Scout生物传感器检测压力的能力之间的关系很差（r = - 0.195, p = 0.013）。结论：与这些参数的“金标准”评估相比，Vital Scout生物传感器提供了准确的能量消耗和呼吸评估。生物传感器具有测量压力的潜力，值得在院外环境中进一步研究。
Introduction: A high prevalence of stress and burnout has been reported among healthcare professionals; however, the current tools utilized to quantify such metrics are not in keeping with doctors' busy lifestyles, and moreover do not comply with infection prevention policies. Given that increased stress can subsequently impact both the healthcare profession and the patient in care, this study aimed to assess the validity of a wearable biosensor to monitor and manage stress experienced by healthcare professionals.Methods: In all, 12 healthy, male volunteers completed an incremental exercise protocol to volitional exhaustion, which aimed to induce physiological stress in a graded manner. A wearable consumer-grade biosensor (Vital Scout, VivaLNK, Inc.) was used to measure stress, energy expenditure, respiration rate, and activity throughout the exercise protocol. These variables were validated against online breath-by-breath analysis (MedGraphics Ultima Series).Results: When compared against online "gold standard" measurements, the Vital Scout biosensor demonstrated a high level of accuracy to measure energy expenditure (r = .776, p < .001) and respiration rate (r = .744, p < .001). The (V) over dotO(2) increase observed during the incremental exercise test was associated with the Vital Scout biosensor's measurement of activity (r = .777, p < .001). In contrast, there was a poor relationship between the changes in (V) over dotO(2) and the Vital Scout biosensor's ability to detect stress (r = -.195, p = .013).Conclusion: The Vital Scout biosensor provided an accurate assessment of energy expenditure and respiration when compared to the "gold standard" assessment of these parameters. Biosensors have the potential to measure stress and deserve further research in the peri-hospital environment.
