Adoption of Lean has also been associated with significant
improvement in patient satisfaction.
A continuous
Press-Ganey patient satisfaction survey showed an
increase in the percentage of patients ranking the overall
ED experience “Very Good” from 54% in 2005 to 59%
in 2006 (p 0.01). The significant improvement we
experienced in patient flow and patient satisfaction was
not associated with a significant increase in inflationadjusted
direct expense per patient (including nurses,
nursing assistants, and medical supplies only), which
was $121 in 2005 and $124 in 2006.
