Factors associated with patients' and companions' satisfaction with a hospital emergency department: A descriptive, cross-sectional study.

Older age was associated with greater satisfaction (p = 0.002), as was female sex (p = 0.013) and greater optimism (p < 0.001). Greater control of pain was a factor associated with satisfaction (p = 0.033), as was the perception of a shorter waiting time before the medical visit (p < 0.001).
