Figure 2. Comparing perceptions of patients, hospitalists, and nurses.

Dichotomized survey data of physicians and nurses were compared to patient responses using chi-square tests. Significant levels of disagreement among the groups were identified for three disruptive factors: alarms [24% (patients) vs. 46% (physicians) vs. 27% (nurses), p = 0.040], and anxiety (18% vs. 21% vs. 38%, p = 0.031) and room temperature (15% vs. 0% vs. 5%, p = 0.031).
