Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The objective of this proposal is to investigate if duloxetine is effective as a third choice pain medication for treating chronic pain in OA compared to usual care;Secondary Objective: Furthermore, we will assess the cost-effectiveness of duloxetine treatment and if the presence of a neuropathic pain component favorably modifies the response to treatment and if the presence of a neuropathic component will be necessary for (cost-)effectiveness.;Primary end point(s): The primary outcome of this study will be pain at 3 months measured with the WOMAC pain subscale.;Timepoint(s) of evaluation of this end point: three months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary outcomes will be pain at one year (WOMAC pain subscale), disability (WOMAC function subscale), adverse reactions, quality of life, compliance to treatment, patients' satisfaction, OARSI-OMERACT, co-interventions, costs (iMCQ, iPCQ);Timepoint(s) of evaluation of this end point: 1 year | — |
