Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Pain Sensitivity and Outcome in Arthroscopic Shoulder Surgery

Further study details as provided by NHS Fife:

Primary Outcome Measures:
  • Degree of correlation between Pain Sensitivity Questionnaire score and 6 month postoperative Rowe/Constant Score. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The degree of correlation between Pain Sensitivity Questionnaire scores and 'Area Under the Curve (AUC)' for postoperative pain experienced (generated from the VAS scores over 4 postoperative days). [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • • The degree of correlation between AUC for postoperative pain and 6 month Constant/Rowe score. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Patients undergoing elective arthroscopic shoulder surgery

Detailed Description:

Arthroscopic shoulder surgery is increasingly performed on a daycase basis. Optimal pain relief is the goal as this not only improves patient comfort and allows expedient discharge from hospital, but also reduces the risk of developing postoperative chronic pain and may improve surgical outcome. However, optimal postoperative pain control in daycase surgery remains a challenge. There is considerable variation in the level of postoperative pain experienced between individuals and subsequent analgesia requirements. Previous studies have attempted to predict the level of postoperative pain an individual will experience, using a variety of complex preoperative pain and psychological assessments. Other investigators have focused on a simpler approach, by testing an individual's pain threshold to a single preoperative nociceptive (painful) stimulus, e.g. heat or pressure. Recent work has produced a simple questionnaire alternative to pain intensity testing, the Pain Sensitivity Questionnaire (PSQ). We hypothesise that a patient's pain sensitivity preoperatively may both affect the level of pain they experience postoperatively and their final surgical outcome.

The aim of our study is to correlate a patient's pain sensitivity, as measured by the Pain Sensitivity Questionnaire, with the degree of acute postoperative pain (first 4 days) they experience and subsequent surgical outcome at 6 months.
