“…The bed-to-nurse ratio was determined by dividing the average number of beds by the average number of full-time-equivalent nurses in general wards as of the first quarter of 2017. This ratio was then segmented into seven intervals: less than 2.0, 2.0–<2.5, 2.5–<3.0, 3.0–<3.5, 3.5–<4.0, 4.0–<6.5, or 6.5 or greater (Kim & Kim, 2021; Park & Ko, 2020). The individual characteristics of nurses were gender (male or female), age (in years) (24 or younger, 25–26, 27–29, 30–34, 35–39, 40–49, or 50 and above), and the duration of employment at the hospital (in years) (less than 1, 1–3, 3–5, 5–10, or 10 and above) (Seo et al, 2020).…”
