Brief Summary
The aim of this study is to assess the effect of a simple intervention (a combination of education and feedback) on Antinuclear Antibody (ANA) testing. This aim was chosen because of the known overuse of many laboratory tests, of which ANA testing is one. As overuse of ANA tests can have negative consequences (both for patients and society), the investigators designed an intervention to see how this would influence Antinuclear Antibody testing by rheumatologists.

Outcome Measures
Primary Outcomes (6)
Change from baseline (pre-intervention) ANA/new patient ratio (APR) at 12 months (post-intervention)
Number of ANA tests divided by the number of new patients
Pre- and post-intervention (both 12 months)
Change from baseline (pre-intervention) % of positive ANA tests at 12 months (post-intervention)
Percentage of ANA tests reported as positive by the local laboratory. ANA tests reported as 'weakly positive' are regarded as negative.
Pre- and post-intervention (both 12 months)
Change from baseline (pre-intervention) % of repeated ANA testing at 12 months (post-intervention)
Percentage of patients with ≥1 ANA test in 12 months (pre- or post-intervention period)
Pre- and post-intervention (both 12 months)
Change from baseline (pre-intervention) % of ANA associated diagnoses at 12 months (post-intervention)
Percentage of patients, in which an ANA is done during the study period, with final diagnosis of SLE, SSc, PM/DM, MCTD or SS
Pre- and post-intervention (both 12 months)
Change from baseline (pre-intervention) APR variation between rheumatologists at 12 months (post-intervention)
Standard deviation around the mean APR, calculated from the APRs of the individual rheumatologists
Pre- and post-intervention (both 12 months)
Change from baseline (pre-intervention) reaching the of target APR at 12 months (post-intervention)
Difference (percentage) between the actual APR and the target-APR defined during the intervention
Pre- and post-intervention (both 12 months)
Study Arms (1)
Education and feedback
EXPERIMENTALThe intervention consisted of a one-hour, small group educational session. During this session information on rational ANA testing was provided and feedback on current ANA testing was provided to the rheumatologists. A booster session with the same components was held 6 months after the first session.
