Do Patients With Chronic Low Back Pain Benefit From Early Intervention Regarding Absence From Work?: A Randomized,...

Area of Science:

• Occupational health
• Rehabilitation medicine
• Clinical trial methodology

Background:

• Chronic low back pain (CLBP) is a significant cause of work absence.
• Norway's priority program for Earlier Return to Work (ERTW) lacks robust evaluation for CLBP populations.
• Limited research exists on the impact of waiting times on return to work (RTW) and standardized RTW measurement.

Purpose of the Study:

• To assess the feasibility of a trial investigating early intervention for CLBP.
• To compare early intervention versus a 3-month waiting list for return to work and sick leave.
• To evaluate outcomes over a 12-month follow-up period.

Main Methods:

• A randomized, controlled, single-center pilot study involving 58 patients.
• Early intervention group assessed within 2 weeks; waiting list group assessed after 12 weeks.
• Identical intensive outpatient back school intervention for both groups; data collected via questionnaires at 3, 6, and 12 months.

Main Results:

• The pilot study suggests a full-scale trial requires at least 382 patients.
• Early intervention did not significantly reduce the number of sick leave days compared to a waiting list after 12 months.
• The primary outcome, absence from work, showed no significant difference between groups.

Conclusions:

• A full-scale clinical trial necessitates a redesigned intervention approach.
• Improvements in patient inclusion and randomization procedures are essential.
• A more precise definition and measurement of return to work (RTW) are required for future studies.
