Abstract:
Objective To design an intelligent and healthy light environment scheme in intensive care unit(ICU)from the experience perspective of nurses,and evaluate its effect on improving nurses'visual perception and work efficiency.Methods According to the Standard for Lighting Design of Buildings(GB50034-2013),reconstruction was performed from the 3 aspects of basic layout,intelligent lighting,and simulated natural light.Then,the usage experience of nurses was investigated via semi-structured interview.By combining the interview results with illuminance and color temperature,the changing curve of light effect was described to finally determine the optimal strategy and form the healthy light environment.Thirty nurses in emergency ICU(EICU)of The First Hospital of Jiaxing before the application of intelligent and healthy light environment from July to October 2023 were selected as the control group,and 30 nurses after the application of intelligent and healthy light environment from January to March 2024 were selected as the observation group.The visual fatigue score of nurses,the completion time of single venipuncture,the occurrence rate of risk events,and the difference in satisfaction of light environment in ICU were compared before and after the establishment of intelligent and healthy light environment.Results After being on duty,the visual fatigue score of nurses in both groups obviously increased,but the scores in the observation group was significantly lower compared to the control group(14.77±2.99 vs.38.43±4.67,P<0.05).Additionly,the completion time of single venipuncture in the observation group was evidently shorter than that in the control group(minutes:4.93±1.82 vs.14.87±2.50,P<0.05),the occurrence rate of risk events in the observation group was remarkably lower than that in the control group[3.33%(1/30)vs.20.00%(6/30),P<0.05],and the satisfaction of light environment in the observation group was distinctly higher than that in the control group[93.33%(28/30)vs.66.67%(20/30),P<0.05].Conclusions Aiming at the special work scenario in ICU,this paper designed intelligent scene lighting and created a bright,comfortable,safe,and healthy light environment,which could effectively relieve nurses'visual fatigue,improve the efficiency and quality of nursing work,and enhance their clinical work experience.Additionally,it provided data support and design strategies for the sound environmental development of ICU.
