In this single-center study, we studied the trends and correlation in the average daily pain scores,
opioid consumption, and patient satisfaction scores as measured by pain-related patient satisfaction questions
in the Hospital Consumer Assessment of Healthcare Providers and System survey. Pain scores and opioid use
data were obtained from electronic health records, vital signs monitoring, and medication databases. Adult
patients who had nonemergent colorectal surgeries between January 2009 and December 2012 were included.
