OBJECTIVE: To examine whether an objective measure of activity scores measured using a sheet-type non-wearable sensor (Nemuri SCAN [NSCAN]) was correlated with agitation levels measured using the modified Richmond Agitation-Sedation Scale (RASS) in terminally ill patients with cancer.
METHODS: We conducted a single-center, prospective, observational study in a palliative care unit using the NSCAN to measure activity scores and the RASS to assess agitation levels. RASS scores were prospectively measured by ward nurses blinded to the NSCAN variables. A database was created to pair the RASS scores and activity scores at night on the same day.
RESULTS: During the observation period, 1209 patients were hospitalized, and 3028 pairs of assessments of 971 patients were analyzed. The NSCAN activity scores significantly increased with increasing RASS scores (Jonckheere-Terpstra test, p < 0.001). The mean values of the activity scores for each RASS score were RASS -5, 28.9; RASS -4, 36.4; RASS -3, 41.7; RASS -2, 57.4; RASS -1, 58.8; RASS 0, 62.6; RASS 1, 79.6; RASS 2, 106.5; and RASS 3, 118.7.
CONCLUSIONS: The NSCAN activity significantly correlated with modified RASS agitation scores. Real-time NSCAN data on agitation may aid timely interventions for optimal symptom control. To improve outcomes for patients suffering from terminal delirium, more research on monitoring tools is warranted.
目的:研究使用非穿戴式传感器(NemuriSCAN[NSCAN])测量的活动评分的客观测量是否与使用改良的里士满激动镇静量表(RASS)测量的激动水平相关。
方法:我们进行了单中心,prospective,在姑息治疗病房进行观察性研究,使用NSCAN测量活动评分,使用RASS评估躁动水平。RASS评分是由对NSCAN变量不知情的病房护士前瞻性测量的。创建了一个数据库,以在同一天晚上将RASS分数和活动分数配对。
结果:在观察期间,1209例患者住院,分析了971例患者的3028对评估结果。NSCAN活动分数随着RASS分数的增加而显着增加(Jonckheere-Terpstra测试,p<0.001)。每个RASS评分的活动评分的平均值为RASS-5,28.9;RASS-4,36.4;RASS-3,41.7;RASS-2,57.4;RASS-1,58.8;RASS0,62.6;RASS1,79.6;RASS2,106.5;和RASS3,118.7。
结论:NSCAN活动与改良的RASS躁动评分显著相关。关于躁动的实时NSCAN数据可能有助于及时干预以实现最佳症状控制。为了改善患有晚期谵妄的患者的预后,有必要对监测工具进行更多研究。
