Chronic Postoperative Pain
Conditions
Brief summary
Shoulder disorders are frequent, often associated with pain and occur in 7-34% of the general population and in 21% of the elderly population. Of particular interest is prediction of postoperative pain after outpatient arthroscopic shoulder surgery since the clinical experience is that surgery does not always provides pain relief and the interindividual variation in acute postoperative pain intensity is significant. In addition, a Swedish study has shown that shoulder operations are associated with longer convalescence than other orthopaedic outpatient surgeries.
Detailed description
This study is a prospective cohort with 6 months follow-up. Patients receive 5 questionnaires (preoperatively, 24 hours, 1 week, 3 months, 6 months, 1 and 2 years after surgery). The questionnaires contain questions about: * Preoperative shoulder pain (type, intensity and duration) * Preoperative pain in other areas besides the shoulder * Brief Pain Inventory (BPI) * Western Ontario Rotator Cuff Index (WORC) * Single Assessment Numeric Evaluation (SANE) * 3 validated physiological questionnaires: * State Trait Anxiety (STAI) * Pain Catastrophizing Scale (PCS) * Hospital Anxiety and Depression Scale (HADS) In addition a cold pressor test is performed on the day of surgery to test the patients' threshold and ability to repress pain.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Chronic postoperative pain | 6 months after surgery | Measured on a numerical rating scale (NRS; 0=no pain and 10=worst possible pain. Chronic postoperative pain is defined as NRS\>=3 with an impact on daily living |
| Acute postoperative pain | 24 hours after surgery | Measured on a numerical rating scale (NRS; 0=no pain and 10=worst possible pain. NRS\>3= acute postoperative pain |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Acute postoperative pain | 1 week after surgery | Measured on a numerical rating scale (NRS; 0=no pain and 10=worst possible pain. NRS\>3= acute postoperative pain |
| Preoperative psychological predictors for chronic pain | 6 months after surgery | Hospital Anxiety and Depression Scale (HADS) |
| Preoperative physical predictors for chronic pain | 6 months after surgery | Cold pressure test |
| Preoperative comorbidity | 6 months after surgery | Other places than the shoulder |
