Relationship between subjective fatigue, physical activity, and sleep indices in nurses working 16-hour night shifts in a rotating two-shift system

Abstract

Objective: We clarified the relationship between the degree of subjective fatigue, sleep, and physical activity among nurses working 16-hour night shifts in a rotating two-shift system.Materials and Methods: We investigated 15 nurses who were surveyed regarding their individual attributes, physical activity level (consumed calories), hours of sleep, sleep efficiency, sleep onset latency, sleep diary, and subjective symptoms. Nurses wore a Fitbit One (Fitbit Inc., San Francisco, CA, USA) for 7 consecutive days to measure sleep and physical activity.Results: Results were analyzed for nine participants, excluding those who withdrew or had missing data. The years of nursing experience, nurses’ age, and the length of nocturnal awakening time of the high fatigue group were significantly longer than of the low fatigue group (p < .05). Years of nursing experience in the affiliated department of the high fatigue group was significantly shorter than of low fatigue group (p < .05). The number of nightshifts during the survey period was significantly higher in the high fatigue group than in the low fatigue group. Fatigue after work and body mass index (r = 0.46, p < .001), consumed calories (r = 0.30, p < .05), bedtime (r = –0.36, p < .05), and hours of sleep (r = –0.37, p < .01) were significantly correlated; however, the sleep indices were not correlated.Conclusion: We clarified that the degree of fatigue in nurses working 16-hour night shifts in a rotating two-shift system was related to individual factors, such as age, years of nursing experience, years of nursing experience in the affiliated department, number of nightshifts, and length of nocturnal awakening time. Nurses with greater fatigue had significant differences in their bedtime on days off and work days, which suggests that sleep rhythm may also affect fatigue.

Impacto de los turnos de trabajo en la calidad del sueño del personal de enfermería en dos hospitales de tercer nivel de Canarias

“…En otros estudios relacionados aconsejan al personal sanitario sometido a turnicidad mantener un patrón de sueño estable los días anteriores y posteriores a los turnos de noche, y hacer una siesta durante el día del turno de noche, y otra "siesta nocturna" durante el turno. De este modo se evita el aumento de fatiga de forma acumulativa para prevenir la fatiga crónica (17) .…”

“…Es recomendable realizar una exhaustiva vigilancia de la salud de los trabajadores sometidos a trabajos a turnos. Desde el ámbito preventivo, se debería realizar una evaluación de riesgos que incluya determinación de aptitud laboral, detección de patologías del sueño, cuestionarios de somnolencia, y derivación temprana al especialista y posterior seguimiento (17) . Desde el ámbito de promoción de la salud sería adecuado llevar a cabo un programa educativo (15) mediante la realización de una intervención colectiva con talleres de higiene del sueño para dotar a los trabajadores de las herramientas necesarias para obtener un sueño reparador y evitar el desarrollo de trastornos del sueño en los mismos con el fin de conseguir mejorar las condiciones de trabajo y la calidad de vida de los trabajadores.…”

Comparison of Chief Surgeons’ and Assistants’ Feelings of Fatigue Between Laparoendoscopic Single‐site and Conventional Laparoscopic Adrenalectomy

“…The subjective feelings of fatigue of the key members of the surgical team were assessed before and after surgery by using the “Jikaku‐sho shirabe” questionnaire (Table 1) [12] assembled by the Industrial Fatigue Research Committee of Japanese Occupational Health. It was designed to assess fatigue and has been widely used in Japan as a reliable tool to assess fatigue in workers [13, 14], including nurses and care workers [15, 16] and surgeons [17]. It consists of 25 subjective items for 5 factors (I: feeling of drowsiness; II: feeling of instability; III: feeling of uneasiness; IV: feeling of local pain or dullness; V: feeling of eyestrain).…”

Veljavnost in zanesljivost vprašalnika o potencialnih dejavnikih stresa zaposlenih v zdravstveni negi v slovenskih bolnišnicah

“…Stresorji zaposlenih v zdravstveni negi se močno razlikujejo glede na zahtevnost delovnega mesta (Henrich, et al, 2017). Pomemben dejavnik stresa zaposlenih v zdravstveni negi je izmensko delo (Zhang, et al, 2017;Kagamiyama & Yano, 2018), zato je izjemnega pomena zadosten čas počitka po končanem delavniku (Tsuchiya, et al, 2017;Bae, et al, 2018;Garcia, et al, 2018). Počitek je zaradi dela, ki presega delovni čas, lahko skrajšan.…”
