Nursing students experience higher levels of stress and more sleep-related problems than other students; however, the relationship of chronotype to nursing students' sleep status and health-related quality of life (HRQOL) is unclear. This cross-sectional, observational study investigated whether chronotype affected Japanese nursing college students' sleep and HRQOL. Nursing students completed the Attribute Questionnaire about Subject Background, Japanese Version Morningness‒Eveningness Questionnaire (MEQ), Munich Chrono-Type Questionnaire‒Japanese Version (MCTQ), Japanese Version of the Pittsburgh Sleep Quality Index (PSQI), SF-12v2 Standard, Japanese Version 2.0 (SF-12), Japanese Translation of Profile of Mood States 2nd Edition‒Adult Short (POMS2). Of the 241 students (mean age 20.16 ± 1.80 years; 80.9% female), 80 (33.2%) had evening, 142 (58.9%) had intermediate, and 19 (7.9%) had morning chronotype. The overall total PSQI score was 6.86 ± 2.97. Additionally, 141 students (64.1%) scored ≥ 6, suggesting disturbed sleep. Approximately 80% of the evening chronotype students had a total PSQI score of 8.34 ± 3.11, clearly indicating disturbed sleep. Sleep-related parameters (total PSQI score, bedtime, sleep latency, wake-up time, sleep duration, social jetlag) were worse in evening than in other chronotypes. SF-12 and POMS2 did not differ among chronotypes. Thus, evening chronotype nursing students require sleep-related support from early on.

Aim To verify our hypothesis that 'there is periodicity in nurse call occurrence'. Background It is difficult to plan nursing management because nursing tasks can vary widely, seemingly at random. One of the most useful pieces of information for decision-making is periodicity. If periodicity is present, it should be possible to predict the occurrence of tasks and make preventive strategies. In this study, we focused on the nurse call, which plays an important role in nursing practice. Method We used nurse call logs that accumulated automatically when patients pushed the button. Data were obtained from 1 January 2014 to 30 September 2017 (1,369 days) in a university hospital. The total number was 5,982,935. Periodicity was verified by the autocorrelation function. Results The value of the autocorrelation function increased regularly, which demonstrates there was periodicity in nurse call occurrence. Conclusion Our hypothesis was accepted. The presence of periodicity indicates that nurse call occurrence is not a random event but has a pattern. Implications for nursing management If we can identify patterns such as the time that nurse calls frequently occur, managers can implement two strategies: one, assigning more nurses and two, moving tasks other than nurse calls to another time.

Lymphedema patients requires long-term treatment. There is no simple way to measure the condition of lymphedema at home. The subcutaneous tissues of lymphedema patients tend to harden the tissue because the amount of water increases as lymph fluid accumulates. The hardness of the subcutaneous tissue includes the information of water content on the lymphedema area. In this study, we developed a device to estimate the water content on the lymphedema area. The measured device consists of an air pack and pressure sensors. When external pressure was applied by the air pack, the reaction force received by the pressure sensor from the area of lymphedema patient was measured. The regression equation was made to estimate the water content from the measured reaction force values. As the results, we could confirm the tight relationship between water content between pressure value.

Body movement is one of the most useful information sources regarding preterm infants' condition and the prediction of motor impairment and/or movement disorders. Professionals observed neuro-developmental impairments like infantile cerebral palsy and assessed general movement for developing motor disorders. In addition, in the neonatal intensive care unit, body movement was used to evaluate developmental care such as the sleep-wake rhythm of infants. Currently, there is no study of a body movement monitoring system for preterm infants within closed incubators. The purpose of this study is to identify the body movement of preterm infants within closed incubators using non-restrictive and non-invasive video processing depending on differences in acoustic environments. Methods: Preterm infants (

This paper discusses the cleaning effect of shampooing care by using Adenosine Triphosphate (ATP) bioluminescence system. Shampooing care is an important nursing one for patients who are difficult to care oneself. It is necessary to perform effective and comfortable care. So, we need to evaluate these effects quantitatively and qualitatively. We measured ATP, blood pressure, heart rate, heart rate variability, peripheral skin temperature and Visual Analog Scale (VAS) before and after shampooing. When we analyzed ATP adhering to head as “contamination” to evaluate that effect quantitatively, it found that the contamination of the scalp after shampooing decreased by 31%, and that of the hair decreased by 22%. The correlation between ATP and VAS showed that the more ATP decreased, the more subjects felt refresh. The physiological index was stable, and it found that the shampoo method in this study had little load on the body. We were able to clarify the cleaning effect of shampooing using rapid and simple method. These results showed can be the basic data that evaluated the effect by shampooing comprehensively.

A nurse is an autonomous, decentralized worker who recognizes goals, his or her environment, the conditions and actions of patients and other staff members, and determines his or her own actions. Put another way, the nurse makes decisions flexibly in the midst of uncertainty. Because of this, nursing work differs from individual nurse to nurse, and understanding this process theoretically is considered to be difficult. Concerning nursing work analysis, research has been done on task load (time required for tasks). However, there has been scant academic research on work processes in nursing compared with research that has accumulated in other industrial fields, including research on structuralizing work, i.e., defining and visualizing work processes. To improve work processes, it is necessary to understand and clarify work as a chain of theoretically related activities. Thus in this study, using time and motion study techniques, a method used to measure jobs, we clarify the structure of the work of transporting patients by nurses. We also attempt to visualize it. We use objected-oriented modeling to express the operation visually.

Disposable diaper is heavy used in care home or hospital. It's often the case that helper doesn't notice that the patient eliminated. This is very discomfort for patient, and bad for the health. They are problem which should be solved. There are conventional incontinence sensor using gas sensor or capped electrode etc. Most of them are large size. So the patient feels something is wrong when he gets on them. It takes a lot of trouble to use because they are not disposable. These sensors are unfamiliar because of those problems. We developed device which make patient's quality of life better. We are writing to suggest that Ultra Small Disposable Defecation Sensor to solve those problem. This sensor is low cost, very small, and comfortable for patient and helper because of disposable. It enables using RFID.

International audience; Patient transportation is one of the daily and frequent jobs in the hospital, however, it requires much strain and time of nurses. We carried out continuous-observation time and motion study (TMS) on the second time scale with recording by the other recorder in four wards of a cardiovascular disease hospital. Based on the recorded data, we carried out time processes modeling (TPM), that visualize the each transportation process sketchy and we could investigate the workflows of transportation as event instance.

International audience; The goal of this study is to measure the impact of electronic medical records on both time efficiency and the work process with regard to outpatient care. In this study, we focus on examining the pre-assessment ahead of the introduction of the electronic medical records procedure applying new methodology, time process study. We extracted 12 use-cases and 82 actions in relation to paper based medical records at an outpatient department at a university hospital using time process study. The results suggest that, for nurses, indirect management of patients accounted for a higher proportion of the use-cases than was the case for direct care.

The aim of this study is to clarify the change over time in the elements of work (job elements) and their features, as well as the relationship between job elements and the type of job, job class, and the role of the hospital they are performed in. A time-motion study was conducted on the medical staff in the surgical wards of two hospitals. An analysis of roles bys by (a) type or class of job type, and (b) hospital function was conducted. The number of working hours was analyzed, as well as the ratio of working hours with respect to direct and indirect job elements. The job elements required for each medical staff member were proven to differ by type of job (doctors and nurses) and also by job class (nurse leaders and staff). When comparing between hospital the differences in job elements were proven not to be a result of differences in hospital function, but to result from the ward system (ward design and nursing system).
