ObjectiveTo examine rates of publicly financed knee arthroscopic surgery in Norway between 2012 and 2016.DesignAnalysis of anonymised data from the National Patient Registry.InterventionsBeginning in 2012, South-Eastern Norway Regional Health Authority implemented administrative measures to bring down rates of knee arthroscopy. Similar measures were not introduced in the other three Regional Health Authorities.Main outcome measuresWe analysed annual national rates of publicly financed knee arthroscopies in 2012 and 2016. We compared the rates in South-Eastern Norway Regional Health Authority with corresponding rates in the rest of the country. Variations by county, public hospital versus publicly reimbursed private hospital, gender and age were also assessed.ResultsThe overall annual rate of arthroscopic procedures declined by 33% from 2012 to 2016, from 310 to 207 per 100 000 inhabitants, respectively. Hospitals in South-Eastern Norway Regional Health Authority reported a 48% reduction, compared with mean 13% in the other three Regional Health Authorities. In public hospitals, rates decreased nationally by 42%, while rates in publicly reimbursed private hospitals increased by 12%. Rates in publicly reimbursed private hospitals decreased by 30% in South-Eastern Norway Regional Health Authority but increased by 63% in the other Regional Health Authorities. The proportion of patients ≥50 years (excluding meniscal repairs) in Norway was 54% in 2012 and fell to 46% in 2016. Average rates per county varied by a factor of 3:1.ConclusionWe report a marked overall reduction of knee arthroscopic procedures from 2012 to 2016 in publicly funded hospitals. The largest decrease was reported in South-Eastern Norway Regional Health Authority, and this coincides in time with implemented administrative measures. The results suggest that the trend of increasing rates of knee arthroscopies can be reversed through purposeful professional and administrative interventions.
Clinician groups appear to order inappropriate MPI at similar rates, regardless of their training, specialty, or practice location. Differences in the most common type of inappropriate testing suggest that interventions to reduce inappropriate use should be tailored to specific clinician types.
Systemic lupus erythematous (SLE) is a systemic auto-immune disorder with a variety of presentations and wide spread organ involvement. We present a case report of a patient with an SLE exacerbation as well as concurrent rhabdomyolysis with massively elevated CPK (304,700 U/L). Though a rarely reported effect of SLE, rhabdomyolysis can be severe and potentially lethal secondary or concurrent to an acute SLE episode. This case report demonstrates the association between SLE and rhabdomyolysis, which is not well described in the current literature.
Inappropriate PET-MPI was rarely abnormal, associated with low catheterization rates, and failed to detect occult ischemia for any subjects. The clinical utility of inappropriate PET-MPI is negligible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
