Primary-care physiotherapist vocational advice and case management,
does it really help with Reduced work absence in workers with musculoskeletal pain?
research showsThe grade is B. In a cluster-randomized trial across six UK general practices and 338 workers, mean four-month absence was 9.3 versus 14.4 days, mean difference -5.1 days, IRR 0.51 (95% CI 0.26-0.99), P=0.048. Only six practices were randomized and the result was borderline.
ads claimThe evidence applies to this early stepped physiotherapist-led vocational service in UK primary care, not every vocational rehabilitation program.
Useful facts when choosing a product
- The key outcome was patient-reported days off work over four months.
- The mean between-group difference was -5.1 days.
- Serious adverse events were not a separate endpoint and no harm signal was reported.
What the research actually shows
SWAP cluster-randomized six general practices and included 338 participants, 158 intervention and 180 control. Four-month days off work was the prespecified primary outcome, with follow-up to 12 months. The abstract did not report four-month questionnaire response, so attrition should not be estimated. A two-sided 5% level and 80% power were declared, but no clinically important absence-day difference was a success threshold. Public and nonprofit support came from NIHR, Arthritis Research UK, and the UK Department of Health.
Why this is classified as B (72)
One publicly funded cluster trial supports a patient-centered functional-economic benefit, giving B with 72 points; six clusters and borderline precision remain limitations.
Counterpoint. Pain and quality-of-life secondary outcomes cannot substitute for the absence result.
Rejudgment record. Cross-check applied — A six-practice cluster-randomized trial found fewer patient-reported absence days at four months with borderline precision
| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced days off work over four months | B | Mean difference was -5.1 days, IRR 0.51. |
| Universal benefit of vocational rehabilitation | D | MI-NAV was null at six months and showed significant absence reductions at 12 months, but was not independent confirmation. |

| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Study 1 | Six-practice cluster-randomized trial | 180 | NIHR, Arthritis Research UK, and UK Department of Health | Patient-reported days off work over four months | 9.3 vs 14.4 days; mean difference -5.1 days; IRR 0.51 (0.26-0.99), P=0.048 | Single publicly funded cluster trial |
| Study 2 | Randomized trial of motivational interviewing or stratified vocational advice versus usual case management | Delivered through the Norwegian Labour and Welfare Administration; authors overlapped with SWAP | Sickness absence at six months | Null sickness-absence difference for stratified vocational advice | Time-point context; not counted as independent replication | |
| Study 3 | Randomized trial of motivational interviewing or stratified vocational advice versus usual case management | 509 | Delivered through the Norwegian Labour and Welfare Administration; authors overlapped with SWAP | Sickness-absence days over 12 months | Stratified vocational advice -17.6 days (95% CI -33.0 to -2.2) and motivational interviewing -15.6 days (95% CI -31.0 to -0.2), each versus usual case management | Positive 12-month context; not counted as independent replication |
