Validation data. van Walraven Brain scans - MRI scan - CT scan - BHF - BHF The ideal entry-level account for individual users. Distributions of demographic variables were similar across health care systems; 51% of individuals were female, the Elixhauser comorbidity score ranged from 0.07 to 0.09 in children (mean, 0.08), from 0.13 to 0.24 in adults (mean, 0.17), and from 0.83 to 1.50 in older adults (mean, 0.96), and the percentage of pregnant women ranged from 0.83% to 1.14% across US health care systems and 0.95% in Ontario. JS, et al. 2023 American Medical Association. This image is an MRI scan of a brain. RK, Brenner For example, all angiographic studies were included if they used CT, MRI, ultrasound, or nuclear medicine, and these study types were included with the specific imaging modality. Drafting of the manuscript: Smith-Bindman. Protecting Access to Medicare Act of 2014, HR 4302, 113th Cong. [Online]. Imaging more wiselyalready at work [letter reply]. Imaging rates for CT, MRI, ultrasound, and nuclear medicine by type of US health care system insurance model (mixed-model vs fully integrated) are shown in Figure 3. It has been estimated that 30% or more of imaging examinations may be unnecessary, costing approximately $30 billion annually in the United States.5 In addition, in a recent study that compared the United States with 10 other countries on various metrics, the United States ranked 1 or 2 in the number of CT and MRI scans performed per 1000 individuals.6, Quiz Ref IDPotential overuse of diagnostic testing has been addressed by the American Board of Internal Medicine Foundations Choosing Wisely campaign7 and by initiatives by payers to reduce imaging through payment reductions.8,9 These efforts are frequently cited to have reduced imaging rates among Medicare beneficiaries.10,11 Most analyses, however, have focused on costs rather than utilization, and changing billing practices, including the bundling of common examinations, makes assessment of utilization and costs different. Objective Author Contributions: Dr Miglioretti had full access to all of the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis. The differences increased over time for CT and diminished over time for MRI. Unfortunately, the magnets in an MRI scanner are solely to help create a clear image and dont possess any healing properties. 2023 American Medical Association. UK guidelines recommend yearly MRI scans from: age 20 . What were the trends in medical imaging from 2000 through 2016 in the United States and Ontario, Canada? The most intensive use of MRI units was also in Hungary (again note that there is incomplete coverage), where an average of 9 100 scans were performed per MRI unit in 2020. Use of diagnostic imaging studies and associated radiation exposure for patients enrolled in large integrated health care systems, 1996-2010. PET scans are commonly used to detect, map, and monitor internal cancers. Main Outcomes and Measures Relative imaging rates were higher among the mixed-model health care plans for ultrasound in older adults (536 vs 390 per 1000 person-years; relative rate, 1.37; 95% CI, 1.31-1.44) and in adults (240 vs 201 per 1000 person-years; relative rate, 1.20; 95% CI, 1.10-1.31) and for nuclear medicine in older adults (73 vs 54 per 1000 person-years; relative rate, 1.36; 95% CI, 1.26-1.46) and in adults (18 vs 13 per 1000 person-years; relative rate, 1.38; 95% CI, 1.24-1.54). . The average annual percentage changes in imaging within fixed time periods stratified by anatomic area are shown in Table 4. Imaging Rates per 1000 Person-Years by Anatomic Area, Imaging Modality, Age, and Country, Based on Joinpoint Analysis, Figure 3. MRIs are a common imaging diagnostic test that doctors recommend for a range of conditions and concerns. Quiz Ref IDUse of computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound in the United States increased rapidly from 2000 to 2006.1,2 Among Medicare beneficiaries, the increase in utilization was higher for medical imaging than other physician-provided services.3,4 Steep increases in imaging can be attributed to technical improvements, physician and patient demand, and strong financial incentives. Quiz Ref IDFirst, the study was limited by including US patients enrolled in a limited number of health care systems, all of which used HMO models of care either in part or in total. Exposures Smith-Bindman R, Kwan ML, Marlow EC, et al. From 2000 to 2016 in 7 US integrated health care systems and Ontario, CT and MRI rates continued to increase among adults, but at a slower pace in more recent years compared with earlier years; in children, CT rates stabilized or declined in recent years. A notable exception was a decline in CT use in children in recent years. Introduction: expert panel on new research on use of imaging services [presentation to Medicare Payment Advisory Commission]. JA, Little Shuryak The UK has 6.1 MRI systems per million people, fewer than countries including Estonia and Slovenia. 6 0 obj A, Stensland et al. An MRI scan can be used to examine almost any part of the body, including the: brain and spinal cord bones and joints breasts heart and blood vessels internal organs, such as the liver, womb or prostate gland Government Accountability Office. Relative rates are for 2016. eFigure 1. CT indicates computed tomography; MRI, magnetic resonance imaging. Customize your JAMA Network experience by selecting one or more topics from the list below. JF It can show tissues, organs and other structures inside your body. After nearly a decade of rapid growth, use and complexity of imaging declined, 2008-14. However, rates were slightly higher for mixed-model plans among adults. Imaging data were mapped across settings, modalities, and anatomic areas to prevent examination double counting and influences from changes in billing practices over time. From 2000 to 2016 in 7 US integrated health care systems and Ontario, CT and MRI rates continued to increase among adults, but at a slower pace in more recent years compared with earlier years; in children, CT rates stabilized or declined in recent years. Calendar year and country (United States vs Canada). Meaning For example, among older adults, in 2000, CT imaging was 204 per 1000 person-years in the United States and 161 per 1000 person-years in Ontario (relative rate, 1.3; 95% CI, 1.2-1.4), whereas in 2016, it was 428 per 1000 person-years in the United States and 409 per 1000 person-years in Ontario (relative rate, 1.0; 95% CI, 1.0-1.1) (Table 2). 2019;322(9):843856. Nuclear medicine imaging declined in adults and children after 2006. 13 0 obj MRI scans are very noisy so you wear ear plugs or headphones. Chubak Changes in annual growth in ultrasound were smaller among adults and children in the United States and Ontario. Healthcare resource statistics - technical resources and medical 3 0 obj Data summaries. Board of Radiation Effects Research, Division on Earth and Life Sciences, National Research Council of the National Academies. Annual growth was 0.8% in the United States and 2.4% in Ontario. et al. Annual rates per 1000 person-years are similar to rates per 1000 persons except that individuals contributed less than a full year during years they were born or died. I, Woskie Design, Setting, and Participants The full billing code list of included studies is available from the authors. For imaging done outside the health care system, information is captured via claims data. Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666 . The focus is primarily on CT because of the relatively high ionizing radiation exposure per examination and large numbers of individuals exposed.29 Adults and children are sensitive to radiation.30-33 In adults, CT use continued to rise, albeit more slowly than seen previously. These data sets were linked using unique encoded identifiers and analyzed at ICES, Toronto, Ontario, before being aggregated with the US data at the University of California, Davis. In addition, what is acceptable clinical practice changes over time. OECD. For MRI, rates were 135 vs 129 per 1000 person-years in older adults (relative rate, 1.05; 95% CI, 0.99-1.11) and 83 vs 77 per 1000 person-years in adults (relative rate, 1.08; 95% CI. Similarly, among older adults, in 2000, MRI use was 62 per 1000 in the United States and 13 per 1000 in Ontario (relative rate, 4.6; 95% CI, 3.8-5.6), whereas in 2016, it was 139 per 1000 person-years in the United States and 89 per 1000 person-years in Ontario (relative rate, 1.6; 95% CI, 1.5-1.7) (Table 2). Overall, 135774532 imaging examinations were included; 5439874 (4%) in children, 89635312 (66%) in adults, and 40699346 (30%) in older adults. Annual percentage changes with 95% confidence intervals are shown in eFigure 1 in the Supplement. endobj Comparing with data from the Organisation of Economic Cooperation and Development (OECD) the UK has one of the lowest number of MRI systems per million population (6.1) yet performs 56.3 scans per 1,000 population, just slightly under the OECD average, clearly demonstrating a very high level of utilisation.8 Furthermore, while respondents Use of computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound in the United States increased rapidly from 2000 to 2006. Wagner Considering the massive amount of MRI scans done every year, its not surprising that the workforce of MRI technologists is estimated to grow by. In children, imaging rates continued to increase except for CT, which stabilized or declined in more recent periods. Usually it's very safe. The US systems included Kaiser Permanente (KP) Hawaii, KP Northern California, and KP Northwest (Oregon), each of which are fully integrated staff model health maintenance organizations (HMOs); KP Washington (which was Group Health Cooperative until 2016), Geisinger (Pennsylvania), Harvard Pilgrim Health Care (Boston, Massachusetts), and Marshfield Clinic Health System (Wisconsin), all of which are mixed-model insurance plans in which patients received care within an HMO or a preferred provider organization under a fee-for-service model of care. 109-171 5102. DJ. Some billing codes changed over time, and all codes were mapped to an anatomic area and imaging modality to ensure consistency over time, updating a previously used map.2 For Ontario data, Canadian Classification of Health Interventions19 codes were used to create a relational table of codes from the United States with codes from Canada to compare imaging rates by imaging modality and anatomic area.
