Analysis and Visualization of Relationship between Stress and Care Activities toward Reduction in Caregiver Workload

Abstract

In Japan, the demand for nursing homes is increasing owing to the rapid aging of the population, and the shortage of caregivers has become a serious problem. This problem has been recognized as a social issue because it increases the workload per caregiver. In response, we have been developing a platform that can easily collect data on nursing care activities to reduce the workload on the basis of the idea that the mental state (i.e., stress) of caregivers, which changes during care activities, might markedly affect their work efficiency. The objective of this study was to obtain new knowledge for reducing the workload of caregivers by visualizing and analyzing their stress. Specifically, we asked caregivers to wear the device, from which we obtained the objective stress indicators of R-R interval (RRI) and low frequency (LF)/high frequency (HF) ratio. We also obtained subjective stress indicators from questionnaires administered before the start of the experiment, before work, during breaks, and after work. To confirm that the stress level of caregivers depends on their care activity, work shift, and workday, we conducted an empirical experiment in an actual nursing home. We distributed devices and applications to five caregivers, obtained measurement data for a total of 28 days, and analyzed and visualized the changes in psychological states related to care activities, work shift, and workdays. As a result, we were able to collect data on the psychological state for 5 to 15 days per caregiver. Furthermore, the analysis of the data showed that, even though objective stress indicators and subjective evaluations did not necessarily coincide, stress tended to increase with specific care activities, work shift, and workdays. In addition, the subjective and objective stress indicators may change depending on the personality of the caregivers themselves.

Autoeficacia De Cuidadores Informales De Personas en Cuidado Paliativo Domiciliario: Revisión Narrativa

“…Respecto a los resultados, la primera categoría describe los factores que disminuyen el desarrollo de la autoeficacia, entre los que estaban los aspectos psicoemocionales y la percepción de sobrecarga del cuidador. En relación con los primeros, varios estudios en cuidadores señalan un alto nivel de estrés, ansiedad y depresión, los que pueden estar asociado a las tareas de cuidado y a las características de personalidad propias de cada cuidador, siendo necesario buscar intervenciones que permitan a los cuidadores sobrellevar el estrés, como es la práctica del mindfulness (13,44,45) , la cual se ha implementado como estrategia de acompañamiento de los equipos de salud. A su vez, en otras poblaciones, se destacan que por sí la sobrecarga es alta en personas que asumen el cuidado de un familiar, especialmente si ese cuidado demanda mayor tiempo personal, esfuerzo físico y psicoemocional, y requerimientos financieros (46) .…”
