Postshift Hand Fatigue in Emergency Service Nurses: Relationships Between Different Functional Tests and Perceived Effort Scores.

Hand functionality, defined as the ability to perform tasks requiring fine motor skills, is crucial for emergency service nurses as it directly affects their ability to perform tasks requiring fine motor skills, such as administering medication, operating equipment, and providing patient care. This study, therefore, aimed to investigate the effects of an 8-h work shift on hand functionality and perceived exertion among emergency service nurses. Employing a cross-sectional design, the study measured manual dexterity, handgrip, and pinch strength, and perceived exertion using the Minnesota Manual Dexterity Test (MMDT), Nine-Hole Peg Test (9-HPT), Handgrip Strength Test, Pinch Strength Test, and the Borg Rating of Perceived Exertion (RPE) Scale. Data were collected from 34 emergency service nurses both before and after their shifts. The present findings indicated significant postshift declines in manual dexterity as evidenced by the MMDT and 9-HPT, with the former demonstrating a large effect size and the latter a small effect size. No significant changes were observed in handgrip and pinch strength. Notably, Borg RPE scores increased significantly postshift, indicating substantial perceived fatigue with a nearly perfect effect size. Correlation analyses revealed significant relationships between increased physical exertion and changes in hand dexterity and strength, underscoring the physical demands placed on nurses during typical work shifts. These findings highlight the need for healthcare institutions to reassess work schedules and ergonomic practices to mitigate fatigue and preserve nurses' hand functionality, thereby enhancing patient care and nurse well-being. The study calls for further research to explore more comprehensive strategies aimed at reducing the occupational strain on emergency service nurses.
