The impact of daylight and views on ICU patients and staff.

Objective: Using a pre-test/post-test quasi-experimental study in two New Hampshire ICUs, the impact of daylight and window views on patient pain levels, length of stay, staff errors, absenteeism, and vacancy rates were examined. One ICU was operational until 2007, the second opened in 2007. ICU patients were randomly selected from cardiac surgery, pneumonia, and chronic obstructive pulmonary disease admissions of one or more days, 58 from the old ICU, and 52 from the new.
