Abstrakt: This study evaluated a pilot intervention to reduce low-value Magnetic Resonance Imaging (MRI) referrals for Low Back Pain (LBP). This before-after intervention study analysed MRI referrals for LBP at two private imaging centres in Norway. MRI referrals for LBP obtained before and after an intervention of information campaigns and sending a return letter to clinicians for declined referrals were evaluated on information, quality, and justification rates. Four radiologists and two radiographers assessed the referrals. A point system was used to calculate referral quality. Each referral was given a score 'good' when rated above 5.5 and 'poor' below 2.5. Justification was based on assessors categorised rating as justified, unjustified or need more information. Stata Statistical Software (Release 18) was used for analysis. A mixed model analysed variations of the referrals pre- and post-intervention. A p-value of <.05 in variations was considered statistically significant. A total n = 300 patients' referrals (150 referrals pre- and post-intervention) were collected and assessed. Post-intervention, 68% of referrals were justified, up from 63% pre-intervention. The assessment showed a 4% decrease in referrals with poor scores and a 2% increase in those rated as good or intermediate quality post-intervention. These changes were not statistically significant. It is important to state that it was not possible in our study to identify the subgroup of referrals that are known to be from clinicians who had received a return letter, although the information campaign targeted all referrers. Despite the limitations our findings suggest that providing reasons for declined referrals can serve as an educational tool for clinicians and contribute to the reduction of low value MRI for LBP. Radiology department initiatives that raise awareness and offer referral criteria guidance to clinicians can serve as valuable educational tools, and further emphasize the importance of providing comprehensive information in MRI referrals for LBP.
