Abstract
BackgroundIndoor daylight levels can directly affect the physical and psychological state of people. However, the effect of indoor daylight levels on the clinical recovery process of the patient remains controversial. This study was to evaluate the effect of indoor daylight levels on hospital costs and the average length of stay (LOS) of a large patient population in general surgery wards.MethodsData were collected retrospectively and analyzed of patients in the Second Affiliated Hospital of Zhejiang University, School of Medicine between January 2015 and August 2020. We measured daylight levels in the patient rooms of general surgery and assessed their association with the total hospital costs and LOS of the patients.ResultsA total of 2,998 patients were included in this study with 1,478 each assigned to two daylight level groups after matching. Overall comparison of hospital total costs and LOS among patients according to daylight levels did not show a significant difference. Subgroup analysis showed when exposed to higher intensity of indoor daylight, illiterate patients had lower total hospital costs (CNY ¥13070.0 vs. ¥15210.3, p = 0.018) and shorter LOS (7 vs. 10 days, p = 0.011) as compared to those exposed to a lower intensity.ConclusionsIndoor daylight levels were not associated with the hospital costs and LOS of patients in the wards of general surgery, except for those who were illiterate. It might be essential to design guidelines for medical staff and healthcare facilities to enhance the indoor environmental benefits of daylight for some specific populations.

Human health is undoubtedly one of the most important considerations for all kinds of environmental designs
1,478 patients were assigned to the low light side group, and 1,478 patients were assigned to the high light side group (Table 1)
We found no significant association between daylight exposure and the hospital costs and length of stay (LOS) of the patients in the wards of general surgery, regardless of their general characteristics, clinical characteristics, and demographic characteristics, namely, lifestyle factors, residential district, etc
Summary
Human health is undoubtedly one of the most important considerations for all kinds of environmental designs. Effect of Indoor Daylight Levels experimental and field research efforts to enhance and the treatment of diseases and accelerate the recovery of patients [1]. As an important environmental factor, daylight levels will directly affect the physical and psychological state of people under certain conditions. Indoor daylight levels can directly affect the physical and psychological state of people. The effect of indoor daylight levels on the clinical recovery process of the patient remains controversial. This study was to evaluate the effect of indoor daylight levels on hospital costs and the average length of stay (LOS) of a large patient population in general surgery wards
