Chronic postoperative pain has an overall incidence of approximately 30%, with 5% to 10% of cases classified as severe (numerical rating scale > 6/10). However, its management remains suboptimal, primarily due to underdiagnosis and delayed referral of patients to specialized chronic pain centers.
Improving the screening of patients with chronic postoperative pain is therefore crucial. Our research has shown that early detection of postoperative neuropathic pain is possible using just two text messages (SMS), as early as three months after surgery. Early screening, combined with prompt management, can prevent pain from becoming chronic and mitigate its harmful effects.
Study design
This study is a cluster crossover randomized trial. All participating centers (n=16) will take part in two sequential study periods:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control period 'without early intervention at 3 months' | No Intervention | During this period, patients with persistent post-operative pain, identified through SMS screening, will be treated at 6 months (this reflects the current standard experience for patients with postoperative pain). | |
| Intervention period 'with early intervention at 3 months' | Experimental | During this period, patients with persistent post-operative pain, identified through SMS screening, will receive early treatment starting at 3 months. |
