dc.description.abstract<i>Background</i> - A vast body of literature has documented regional variations in healthcare utilization rates. The extent to which such variations are “unwarranted” critically depends on whether there are corresponding variations in patients’ needs. Using a unique medical registry, the current paper investigated any associations between utilization rates and patients’ needs, as measured by two patient-reported outcome measures (PROMs).<p> <p><i>Methods</i>- This observational panel study merged patient-level data from the Norwegian Patient Registry (NPR), Statistics Norway, and the Norwegian Registry for Spine Surgery (NORspine) for individuals who received surgery for degenerative lumbar spine disorders in 2010–2015. NPR consists of hospital administration data. NORspine includes two PROMs: the generic health-related quality of life instrument EQ-5D and the disease-specific, health-related quality of life instrument Oswestry Disability Index (ODI). Measurements were assessed at baseline and at 3 and 12 months post-surgery and included a wide range of patient characteristics. Our case sample included 15,810 individuals. We analyzed all data using generalized estimating equations.<p> <p><i>Results</i> - Our results show that as treatment rates increase, patients have better health at baseline. Furthermore, increased treatment rates are associated with smaller health gain.<p> <p><i>Conclusion</i> - The correlation between treatment rates and patients health indicate the presence of unwarranted variation in treatment rates for lumbar spine disorders.en_US
