Overview

The R³ trial is a multicentre cluster randomized controlled trial evaluating an evidence-based, person-centred rehabilitation pathway for patients undergoing lumbar surgery for radicular pain. The pathway includes structured pre-, peri-, and postoperative rehabilitation, early postoperative mobilization, case management, early return-to-work (RTW) guidance, and patient empowerment. Clusters (hospitals) are randomized to implement the R³ pathway (intervention) or continue usual care (control). The primary aim is to determine whether the R³ pathway reduces time to return to work compared with usual care.

Eligibility

Inclusion Criteria:

• Radicular pain (for ≥ 6 weeks prior to screening), with a clear indication for lumbar spinal surgery ((micro)discectomy, decompression and/or fusion), in accordance with the KCE guidelines (when evidence-based multimodal management has not improved pain or function and radiological findings are consistent with clinical symptoms)
• Employed (working or on sick leave for less than 1 year due to spinal pathology)
• Age 18 - 65 years
• Surgery is scheduled within a timeframe of five days to 2 months after the decision for surgery (4 months for fusion)
• For lumbar fusion surgery, the fusion should be restricted to one or two levels
• Able to provide written informed consent, implying that the participant is both physically and cognitively capable of understanding the study information and signing the consent form independently.

Exclusion Criteria:

Patients are not eligible for the trial in case of any of the following criteria:

• Lumbar surgery performed for malignant disease, spinal fracture, infectious spinal disease
• Insufficient knowledge of Dutch or French language to receive education in the recruiting center and to complete the questionnaires (consistent with the language spoken in the recruiting centre)
• Immediate surgery via emergency admission that precludes prehabilitation
• Revision fusion surgery
• Non-residency in Belgium
