2. Background: RSI known since 1700 in Bernardino Ramazzini’s
“De Morbis Artificum Diatriba”
most registred occupational disease in The Netherlands
lot of studies: focus on short-term complaints somewhere in upper extremity in working populations
lack of studies in larger groups of chronic RSI patients
lack of knowledge about what may be important for the ability to work with these complaints
RSI Dutch patient association: 1700 members in 1999,
3250 members in 2005
3. Objective to study differences between the perspectives of
working and sick-listed Dutch chronic RSI patients’
with respect to indices of quality of life and illness
representation
4. Methods data from questionnaire study 2005
N= 1121; members of the RSI patient association
demographics
work-status (working or presently sick-listed)
complaint-related variables: type, severity, duration, extent
cause of RSI
5. Methods: dependent and independent variables quality of life (QoL):
SF-36 subscales
current work-ability compared to best ever (0-10)
percentual complaint-related QoL deterioration calculated through two VAS-scales that asked to rate QoL with respect to
current general health (0-100) and
general health before the RSI-complaints existed (0-100)
illness representation: brief illness perception questionnaire (B-IPQ) (Broadbent et al., 2006)
comparison between working and sick-listed patients
(statistical and in terms of clinically relevant differences)
6. Results (1): demographics
7. Main cause RSI complaints?RSI working (n=745), sick-listed (n=376)
8. Location of complaints? 8 regionsChronic RSI-patients (n=1121)
9. Duration, extent and severity of complaintsRSI working (n=745), sick-listed (n=376)
10. QoL(1): SF-36 domains (higher scores are better QoL)
11. QoL (2): current estimated work-ability compared to best ever(10)
12. Decrease in QoL because of RSI complaints
14. Clinically relevant differences in illness representation Consequences: how much does your illness affect your life (not at all, to severely)
Treatment control: how much do you think your treatment can help your illness? (not at all, to extremely helpful)
Identity: how much do you experience symptoms from your illness? (no symptoms at all, to many severe symptoms)
15. Conclusions
