Outcome Measures

Primary Outcomes (1)

  • Chronic post surgical pain

    Pain related to the surgical procedure measured as average pain intensity on rest or movement using 11-point numeric rating scale (NRS; 0-10) where 0=no pain and 10=worst pain imaginable and/or average pain interference using 11-point NRS among any one of seven short-form Brief Pain Inventory items (general activity, mood, walking ability, normal work (including housework), relations with other people, sleep, enjoyment of life) in the past one week, where 0=pain does not interfere and 10=pain completely interferes.

    3 months post surgery

Secondary Outcomes (1)

  • Acute post surgical pain

    First 3 hours after surgery
