“…(Alimoglu al., 2014), visual task performance (Figueiro et al, 2006), and medication dispensing errors (Buchanan et al, 1991). The existing studies also show the relationship between light exposure and patient outcomes including patient satisfaction (Gharaveis et al, 2016), length of stay (Beauchemin & Hays, 1996;Benedetti et al, 2001;Choi et al, 2012;Park et al, 2018), mood (Beauchemin & Hays, 1996;Walch et al, 2005), pain (Walch et al, 2005;Zadeh et al, 2014), and sleep (Hadi et al, 2019). Within the context of these studies, lighting has been measured through a variety of metrics such as: Based on prioritization of metrics, we selected duration of exposure and illuminance levels as the lighting metrics to implement in calculations.…”
