The purpose of this study is to provide preliminary data for a Program Project Grant to the National Institutes of Health to examine specific explanations regarding identifying patients at risk for chronic pain after surgery and identifying mechanisms which may be altered to decrease this risk.

This study will help investigators better understand chronic pain that develops after surgery. We are proposing to study different factors related to the surgical experience and factors in the environment to determine if any play a role in the development of chronic pain after surgery.

Primary Outcome Measures:
  • Self-reported pain intensity [ Time Frame: Hospital Discharge to day 168 ] [ Designated as safety issue: No ]

    To obtain estimates of pain intensity, we will use the McGill Pain Questionnaire - Short Form (MPQ).

    The questionnaire will be completed as follows:

    3 times/day: Hospital discharge through day 14 Once daily: Day 15 through day 28 Once weekly: Day 29 through day 85 Once monthly: Day 86 through day 168

Biospecimen Retention:   Samples With DNA
