Clinimetric properties of the EuroQol-5D in patients with chronic low back pain

Patient preference with respect to QoL and reduction in opioid‐induced constipation ( OIC ) after treatment with prolonged‐release ( PR ) oxycodone/naloxone compared with previous analgesic therapy [ PREFER study]

“…Soer et al recently established minimally clinical important differences in EQ-5D of 0.03 for chronic low back pain patients after multidisciplinary treatment at a specialty centre for spinal disorders (31). The majority of the patients in this study were chronic low back pain patients (similar to the patients studied by Soer et al).…”

EQ-5D-derived health utilities and minimally important differences for chronic health conditions: 2011 Commonwealth Fund Survey of Sicker Adults in Canada

“…Walters and Brazier [19] also used the one half SD method, which produced slightly larger MIDs. In a Netherlands study, Soer et al [41] estimated the MID for patients with chronic back pain to be 0.03. Marra et al [22] estimated the MID for rheumatoid arthritis to be 0.05.…”

Physiotherapy triage assessment of patients referred for orthopaedic consultation – Long-term follow-up of health-related quality of life, pain-related disability and sick leave

“…A retrospective sample size calculation was made for this study using the EQ VAS, which have the suggested minimal clinically important change (MCIC) of 10.5 units (Soer et al, 2012a). Calculation showed that 63 patients in each group would have been sufficient to detect differences in MCIC at the p < 0.05 level, with a power of 80%.…”

“…Also, the subjects are asked to rate their current health state on a vertical visual analogue scale (EQ VAS) with the endpoints 0 (worst imaginable health state) and 100 (best imaginable health state). The EQ-5D has evidence of validity and reliability in different musculoskeletal disorders (Soer et al, 2012a) and orthopaedics (Beard et al, 2010;Devine et al, 2011). The Swedish version of the EQ-5D was used for this study.…”
