Radiology quick cash? Kickbacks, compliance, and consequences. Curr Probl Diagn Radiol 2024:S0363-0188(24)00097-5. [PMID: 38760235 DOI: 10.1067/j.cpradiol.2024.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Accepted: 05/06/2024] [Indexed: 05/19/2024]
Abstract
The Anti-Kickback Statute was passed by Congress in the 1970s to reduce the overuse of government-reimbursed medical services. It attempts to eliminate fraud, abuse, and waste of medical services by outlawing the incentive of personal gain when referring patients for government-funded services. Although safe harbors were written into the law to maintain transactions beneficial to society, they require strict adherence. Anti-Kickback Statute violations are subject to the whistleblower provision of the False Claims Act, and violations can yield significant civil and criminal penalties.

Which health conditions report the most spending on medical imaging? Evidence for Colombia. Curr Probl Diagn Radiol 2024:S0363-0188(24)00079-3. [PMID: 38714393 DOI: 10.1067/j.cpradiol.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Accepted: 05/01/2024] [Indexed: 05/09/2024]
Abstract
Medical imaging is essential for the proper diagnosis and treatment of many diseases. The literature has found that medical imaging generally accounts for a significant percentage of total healthcare spending. We analyzed a national database between 2013 and 2021, with more than 19 million patients on average, to review which health conditions account for the highest spending on medical imaging in the Colombian health system. We segmented the analysis by type of medical imaging, life cycles, health condition and sex. Our findings indicate that cardiac and mental illnesses account for the highest per capita spending on medical imaging, especially for the elderly. As a proportion of total expenditure, hypertension and tuberculosis are added, with special emphasis on the infancy-childhood life cycle.

Scanners, schedules, and statutes: A tale of trauma, policy, and profit. Curr Probl Diagn Radiol 2024; 53:332-334. [PMID: 38461098 DOI: 10.1067/j.cpradiol.2024.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Accepted: 03/06/2024] [Indexed: 03/11/2024]
Abstract
EMTALA (Emergency Medicine Treatment and Labor Act) is an important federal mandate intended to improve access to emergency medical services for patients regardless of financial means. The act imposes strict guidelines on emergency departments, associated referral specialists, and ancillary services. Radiology departments must comply with all ETMALA requirements to avoid potentially incapacitating penalties to their institutions.

Contemporary Management of Blunt Splenic Trauma in Adults: An Analysis of the Trauma Quality Improvement Program Registry. J Am Coll Radiol 2024:S1546-1440(24)00291-6. [PMID: 38492766 DOI: 10.1016/j.jacr.2024.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 02/06/2024] [Accepted: 03/01/2024] [Indexed: 03/18/2024]
Abstract
PURPOSE The aim of this study was to evaluate the effectiveness of management strategies for blunt splenic injuries in adult patients. METHODS Patients 18 years and older with blunt splenic injuries registered via the Trauma Quality Improvement Program (2013-2019) were identified. Management strategies initiated within 24 hours of hospital presentation were classified as watchful waiting, embolization, surgery, or combination therapy. Patients were stratified by injury grade. Linear models estimated each strategy's effect on hospital length of stay (LOS), intensive care unit (ICU) LOS, and mortality. RESULTS Of 81,033 included patients, 86.3%, 10.9%, 2.5%, and 0.3% of patients received watchful waiting, surgery, embolization, and combination therapy, respectively. Among patients with low-grade injuries and compared with surgery, embolization was associated with shorter hospital LOS (9.4 days, Q < .001, Cohen's d = .30) and ICU LOS (5.0 days, Q < .001, Cohen's d = .44). Among patients with high-grade injuries and compared with surgery, embolization was associated with shorter hospital LOS (8.7 days, Q < .001, Cohen's d = .12) and ICU LOS (4.5 days, Q < .001, Cohen's d = .23). Among patients with low- and high-grade injuries, the odds ratios for in-hospital mortality associated with surgery compared with embolization were 4.02 (Q < .001) and 4.38 (Q < .001), respectively. CONCLUSIONS Among patients presenting with blunt splenic injuries and compared with surgery, embolization was associated with shorter hospital LOS, shorter ICU LOS, and lower risk for mortality.

Decomposition of medical imaging spending growth between 2010 and 2021 in the US employer-insured population. HEALTH AFFAIRS SCHOLAR 2024; 2:qxae030. [PMID: 38756926 PMCID: PMC10986240 DOI: 10.1093/haschl/qxae030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 02/28/2024] [Accepted: 03/05/2024] [Indexed: 05/18/2024]
Abstract
Medical imaging, identified as a potential driver of unsustainable US health care spending growth, was subject to policies to reduce prices and use in low-value settings. Meanwhile, the Affordable Care Act increased access to preventive services-many involving imaging-for employer-sponsored insurance (ESI) beneficiaries. We used a large insurance claims database to examine imaging spending trends in the ESI population between 2010 and 2021-a period of considerable policy and benefits changes. Nominal spending on imaging increased 35.9% between 2010 and 2021, but as a share of total health care spending fell from 10.5% to 8.9%. The 22.5% growth of nominal imaging prices was below inflation, 24.3%, as measured by the Consumer Price Index. Other key contributors to imaging spending growth were increased use (7.4 percentage points [pp]), shifts toward advanced modalities (4.0 pp), and demographic changes (3.5 pp). Shifts in care settings and provider network participation resulted in 2.5-pp and 0.3-pp imaging spending decreases, respectively. In sum, imaging spending decreased as a share of all health care spending and relative to inflation, as intended by concurrent cost-containment policies.

Abstract
PURPOSE The aim of this study was to analyze current radiology practice types, specific subspecialty needs, employment trends, and retirement trends. METHODS ACR members, nonmembers, and Radiology Business Management Association members were surveyed using predominantly structured closed-ended questions about a variety of current and recent radiology practice characteristics. Responses were group practice deduplicated and weighted. RESULTS Of 1,702 survey respondents, 64% were men, with a median age of 51 years. In 2021, 62% of responding practices hired radiologists, with the average practice hiring 2 radiologists and academic practices on average hiring the most (3.5). Most radiologists (87%) were hired for full-time positions, with independent practices hiring the largest proportion of part-time positions. Body and breast imagers represented the largest numbers of hired radiologists (17% each). Practices anticipated similar hiring patterns in 2022, prioritizing breast (37%) and body (35%) imaging. Of all practice types, academic groups were least likely to prioritize general radiologist hiring. A large majority (82%) of radiology practices permit remote work (teleradiology), more common at academic than other practices. Of currently employed radiologists, 16% plan to seek new employment in the next year; early-career radiologists indicated the highest likelihood (92%) and academic radiologists the lowest (66%) of remaining in the same practice for at least 5 years. A large majority of practices (80%) reported no radiologist retirements in 2021. Of those retiring, the average age was 75 years, and 66% worked full-time until retirement. CONCLUSIONS Radiologist recruiting remains robust. Current information on practice characteristics may help inform radiology practice leaders seeking to right-size their groups.

Abstract
PURPOSE With social media becoming a vibrant hub for the radiology community, highlighting expert leaders and trustful conduits of information in the virtual field is proving crucial. The aim of this study was to identify and describe the most prominent and influential figures and organizational accounts to follow in radiology. METHODS Influence scores for the topic "radiology" on Twitter (now known as X) were computed using the Right Relevance machine learning service. Top influencers were classified according to gender, geography, physician degree, areas of influence, subspecialization, influence score, title, affiliated institution, dual degree, medical school origin, content type, and research activity. Statistical analysis was performed assessing variable correlations. RESULTS In the top quartile of influential figures, 87% were physicians, 60% men, and 93% located in the United States. Prevalent backgrounds included neuroradiology (21%), abdominal imaging (12%), and artificial intelligence (11%). Of the top 100 figures, 81% were US graduates, 97% held medical degrees, and 28% had dual degrees. Fifty-eight percent provided educational content. A majority held leadership positions (58%) and academic professorship titles (70%). The median h index, publication number, and citation number were 14, 49, and 881, respectively. No significant correlation was noted between influence score and academic rank or research output. CONCLUSIONS Virtual presence is becoming integral to health care professions and academic spheres, unfolding great potential for enhancing the sense of belonging, advocacy, recruitment, and fostering new relationships. Having a core of influential leaders and organizations to follow can serve as a resource for the community members and aspiring students building a positive connected basis for radiology's thriving future.

An Examination of Racial and Ethnic Disparities in the Use of Prostate Biopsy and Magnetic Resonance Imaging in Prostate Cancer Screening. UROLOGY PRACTICE 2023; 10:612-619. [PMID: 37498656 DOI: 10.1097/upj.0000000000000435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 06/30/2023] [Indexed: 07/28/2023]
Abstract
INTRODUCTION We assessed racial and ethnic disparities in the use of prostate biopsy or MRI following an elevated PSA result. METHODS We retrospectively evaluated insurance claims from Optum's de-identified Clinformatics Data Mart database from January 1, 2011 to December 31, 2017. This was a large commercially insured cohort from across the United States. We included all male enrollees over 40 years old receiving an elevated PSA result with no prior prostate biopsy or MRI and no confirmed urinary tract infection within 6 weeks of PSA test. RESULTS A total of 765,409 participants met inclusion criteria with 43,711 (5.71%) receiving a PSA result above 4 ng/mL. Of these, 7,399 received either a prostate biopsy or MRI within 180 days. Men between ages 40-54 (29.48%) were most likely to receive prostate biopsy or MRI after an elevated PSA, followed by those between 55-64 (24.91%), 65-74 (18.56%), 75-84 (6.33%), and above 85 (3.62%). Compared to White patients, Black patients were more likely to receive either a prostate biopsy or MRI (OR: 1.16, 95% CI: 1.01, 1.32) following an elevated PSA level, while Asian (OR: 0.72, 95% CI: 0.54, 0.96) and Hispanic (OR: 0.83, 95% CI: 0.70, 0/97) patients were less likely. CONCLUSIONS Physicians appear to be following the reported statistical incidence of prostate cancer by race and ethnicity when using prostate biopsy or MRI for patients with elevated PSA levels. These results demonstrate the importance of publishing statistical data on disease incidence by race and ethnicity for informing physicians' decision-making.

Financial Impact of Imaging Examination Site of Service in the Medicare Population. Curr Probl Diagn Radiol 2023; 52:522-527.

Abstract
PURPOSE The financial sustainability of the US healthcare system is a growing concern in an environment of declining reimbursement and rising costs. Variable Centers for Medicare and Medicaid (CMS) reimbursement and denial rates for specific imaging examinations exist across sites of service, adding complexity to financial planning for healthcare organizations. Understanding the financial implications of site of service in existing CMS reimbursement for imaging may be of strategic importance for organizations going forward. MATERIALS AND METHODS Current Procedural Terminology (CPT) codes were obtained for common cross-sectional imaging examinations using the 2022 CMS Medicare Physician Fee Schedule. Using reimbursement rates with historical volumes and denial rates, a simulation was created to estimate the overall reimbursement of paired hospital outpatient departments (HOPD) and free-standing office (FSO) sites. A baseline simulation was performed with random allocation of imaging examinations between sites of service, and an optimized simulation was performed to estimate the maximum financial impact of targeted allocation between sites. These simulations were performed for paired CT and MR scanners separately. RESULTS For CT, the baseline simulation estimated annual average reimbursement for combined HOPD and FSO was $3.25M. Reimbursement increased to $3.51M after optimized reallocation of studies between sites of service, resulting in an expected gain of $260,162 for a set of paired HOPD and FSO scanners. For MR, the same approach resulted in baseline reimbursement of $2.51M, increasing to $2.60M upon reallocation between sites for an expected gain of $87,532. Assuming a stable cost of service delivery, this approach would result in improved margins of 8% for CT and 3.5% for MR. There were 28 CT and 19 MRI daily patient imaging appointments at each respective HOPD and FSO scanners, unchanged between baseline and optimized cases. Differences in reimbursement rates between sites were the dominant driver of increased margins at low denial rates, although denial rates became dominant at values greater than 50%. CONCLUSION Given CMS payment and denial rate variability, optimally allocating imaging studies between sites of service may improve reimbursement for the same services delivered. Although financial incentives exist for site allocation, such decisions should require physician input to assess safety and appropriate level of care. This work contributes to an understanding of financial incentives of existing reimbursement policy and may guide future policy design towards high value care.

Are Academic Emergency Radiologists Systematically Disadvantaged Compared With Diagnostic Radiology Subspecialty Counterparts When It Comes to Promotion? J Am Coll Radiol 2023; 20:1063-1071. [PMID: 37400045 DOI: 10.1016/j.jacr.2023.03.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 03/09/2023] [Accepted: 03/27/2023] [Indexed: 07/05/2023]
Abstract
PURPOSE The aim of this study was to assess academic rank differences between academic emergency and other subspecialty diagnostic radiologists. METHODS Academic radiology departments likely containing emergency radiology divisions were identified by inclusively merging three lists: Doximity's top 20 radiology programs, the top 20 National Institutes of Health-ranked radiology departments, and all departments offering emergency radiology fellowships. Within departments, emergency radiologists (ERs) were identified via website review. Each was then matched on career length and gender to a same-institutional nonemergency diagnostic radiologist. RESULTS Eleven of 36 institutions had no ERs or insufficient information for analysis. Among 283 emergency radiology faculty members from 25 institutions, 112 career length- and gender-matched pairs were included. Average career length was 16 years, and 23% were women. The mean h indices for ERs and non-ERs were 3.96 ± 5.60 and 12.81 ± 13.55, respectively (P < .0001). Non-ERs were twice as likely as ERs (0.21 versus 0.1) to be associate professors at h index < 5. Men had nearly 3 times the odds of advanced rank compared with women (odds ratio, 2.91; 95% confidence interval, 1.02-8.26; P = .045). Radiologists with at least one additional degree had nearly 3 times the odds of advancing rank (odds ratio, 2.75; 95% confidence interval, 1.02-7.40; P = .045). Each additional year of practice increased the odds of advancing rank by 14% (odds ratio, 1.14; 95% confidence interval, 1.08-1.21; P < .001). CONCLUSIONS Academic ERs are less likely to achieve advanced rank compared with career length- and gender-matched non-ERs, and this persists even after adjusting for h index, suggesting that academic ERs are disadvantaged in current promotions systems. Longer term implications for staffing and pipeline development merit further attention as do parallels to other nonstandard subspecialties such as community radiology.

Abstract
OBJECTIVE We aimed to assess the changing share of diagnostic imaging billed by NPPs and how such changes differ by urbanicity within the context of scope-of-practice (SOP) regulations and legislation. METHODS This retrospective cohort study used patient claims for diagnostic imaging studies spanning 2016-2020 from Optum Clinformatics Datamart datasets. Multivariable modeling determined the odds of patients receiving NPP-interpreted vs physician-interpreted imaging. Imaging rates and trends in proportions of NPP-billed claims were assessed by urbanicity and relative to other factors including SOP, imaging modality, and place of service. RESULTS Of all identified imaging claims, 3,348,881 (3.0%) were attributed to NPPs, with the highest rates of NPP interpretations per 10,000 images occurring in rural and small-town areas. From 2016 to 2020, the rate of NPP-billed imaging increased from 257 to 331 claims per 10,000 beneficiaries (P = 0.004), observed across both metropolitan (240 to 315, P = 0.001) and micropolitan (367 to 436, P = 0.020) settings. Although rates in rural and small-town areas rose, the increase was not significant (330 to 392, P = 0.363). Rises in NPP imaging in metropolitan settings occurred in states with moderately restrictive (307 to 358, P = 0.008) and least restrictive (289 to 419, P = 0.004) SOP legislation. DISCUSSION Rates of diagnostic imaging interpretation by NPPs are rising. Growth in recent years appears driven by metropolitan areas in states with less restrictive SOP regulations. Future work is necessary to assess the quality of and downstream costs related to increasing NPP-interpreted imaging.

Abstract
BACKGROUND Examine the association of metformin use and overall survival (OS) in patients with HCC undergoing image-guided liver-directed therapy (LDT): ablation, transarterial chemoembolization (TACE), or Yttrium-90 radioembolization (Y90 RE). METHODS Using National Cancer Institute Surveillance, Epidemiology, and End Results registry and Medicare claims databases between 2007 and 2016, we identified patients ≥ 66 years who underwent LDT within 30 days of HCC diagnosis. Patients with liver transplant, surgical resection, and other malignancies were excluded. Metformin use was identified by at least two prescription claims within 6 months before LDT. OS was measured by time between first LDT and death or last Medicare observation. Comparisons were performed between both all and diabetic patients on and not on metformin. RESULTS Of 2746 Medicare beneficiaries with HCC undergoing LDT, 1315 (47.9%) had diabetes or diabetes-related complications. Among all and diabetic patients, 433(15.8%) and 402 (30.6%) were on metformin respectively. Median OS was greater for patients on metformin (19.6 months, 95% CI 17.1-23.0) vs those not (16.0 months, 15.0-16.9; p = 0.0238). Patients on metformin had lower risk of death undergoing ablation (HR 0.70; 0.51-0.95; p = 0.0239) and TACE (HR 0.76, 0.66-0.87; p = 0.0001), but not Y90 RE (HR1.22, 0.89-1.69; p = 0.2231). Among diabetics, OS was greater for those on metformin vs those not (HR 0.77, 0.68-0.88; p < 0.0001). Diabetic patients on metformin had longer OS undergoing TACE (HR 0.71, 0.61-0.83; p < 0.0001), but not ablation (HR 0.74, 0.52-1.04; p = 0.0886) or Y90 RE (HR 1.26, 0.87-1.85; p = 0.2217). CONCLUSION Metformin use is associated with improved survival in HCC patients undergoing TACE and ablation.

Abstract
PURPOSE To evaluate the effectiveness of management strategies for blunt liver injuries in adult patients. MATERIALS AND METHODS Patients 18 years and older with blunt liver injuries registered via the Trauma Quality Improvement Program (2007-19) were identified. Management strategies initiated within 24 hours of hospital presentation were classified as non-operative management (NOM), embolization, surgery, or combination therapy. Patients were stratified by injury grade. Linear models estimated each strategy's effect on hospital length of stay (LOS), intensive care unit (ICU) LOS, ventilator dependence, and mortality. RESULTS Of 78,127 included patients, 88.7%, 8.7%, 1.8%, and 0.8% of patients received NOM, surgery, embolization, and combination therapy, respectively. Among patients with low- (n = 62,237) and high-grade (n = 15,890) injuries and compared to all other management strategies, NOM was associated with the shortest hospital LOS and ICU LOS. Among patients with low-grade injuries and compared to surgery, embolization was associated with a shorter hospital LOS (9.7 days, P < .001, Cohen's d = .32) and ICU LOS (5.3 days, P < .001, Cohen's d = .36). Among patients with high-grade injuries and compared to surgery, embolization was associated with a shorter ICU LOS (6.0 days, P < .01, Cohen's d = .24). Among patients with low- and high-grade injuries and compared to embolization, surgery was associated with higher odds of mortality (P < .001). CONCLUSIONS Among patients presenting with blunt liver injuries and compared to surgery, embolization was associated with a shorter ICU LOS and lower risk of mortality.

[PMID: 37001939 DOI: 10.1016/j.jacr.2022.12.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 12/16/2022] [Accepted: 12/23/2022] [Indexed: 03/31/2023]
Abstract
OBJECTIVE Lung cancer screening does not require patient cost-sharing for insured people in the U.S. Little is known about whether other factors associated with patient selection into different insurance plans affect screening rates. We examined screening rates for enrollees in commercial, Medicare Fee-for-Service (FFS), and Medicare Advantage plans. METHODS County-level smoking rates from the 2017 County Health Rankings were used to estimate the number of enrollees eligible for lung cancer screening in two large retrospective claims databases covering: a 5% national sample of Medicare FFS enrollees; and 100% sample of enrollees associated with large commercial and Medicare Advantage carriers. Screening rates were estimated using observed claims, stratified by payer, before aggregation into national estimates by payer and demographics. Chi-square tests were used to examine differences in screening rates between payers. RESULTS There were 1,077,142 enrollees estimated to be eligible for screening. The overall estimated screening rate for enrollees by payer was 1.75% for commercial plans, 3.37% for Medicare FFS, and 4.56% for Medicare Advantage plans. Screening rates were estimated to be lowest among females (1.55%-4.02%), those aged 75-77 years (0.63%-2.87%), those residing in rural areas (1.88%-3.56%), and those in the West (1.16%-3.65%). Among Medicare FFS enrollees, screening rates by race/ethnicity were non-Hispanic White (3.71%), non-Hispanic Black (2.17%) and Other (1.68%). CONCLUSIONS Considerable variation exists in lung cancer screening between different payers and across patient characteristics. Efforts targeting historically vulnerable populations could present opportunities to increase screening.

Abstract
BACKGROUND Intracranial mechanical thrombectomy (MT) is increasingly indicated for use in acute ischemic stroke patients. We analyzed recent trends in the characteristics and geographic distributions of physicians providing this service with frequency to Medicare beneficiaries. METHODS We linked public data sources to elucidate and visualize trends in high-volume MT providers between 2016 and 2019. RESULTS High-volume MT providers increased by 184% between 2016 and 2019. The number of neurosurgeons, neurologists, and radiologists in this physician population increased by 251%, 205%, and 139%, respectively. Male practitioners accounted for 96% of providers in the most recent year of analysis. International medical graduates accounted for roughly one-third of these physicians across all 4 years of analysis. As of 2019, the three states with the most high-volume MT providers were Florida, California, and Texas, accounting for 7%, 7%, and 6% of providers, respectively. CONCLUSIONS High-volume providers of MT services for Medicare beneficiaries represent a dynamic and rapidly expanding subset of physicians with diverse specialty backgrounds.

Abstract
The Center for Medicare and Medicaid Services noted skin biopsies have high expenditures and changed biopsy billing codes in 2018 to better align procedure type and associated billings. We examined associations between billing code updates and skin biopsy utilization and reimbursement across provider specialties. While dermatologists perform most skin biopsies, the proportion of skin biopsies performed by dermatologists has continuously decreased, but the proportion of skin biopsies performed by nonphysician clinicians has increased from 2017-2020. After the code update, the non-facility national payment amount decreased for first tangential biopsy but increased for first punch, first incisional, additional tangential, additional punch and additional incisional biopsy compared to the corresponding amount for first and additional biopsy before the code update. The allowable charges and Medicare payment per skin biopsy increased across provider specialties but has increased the most for primary care physicians from 2018-2020.

Abstract
PURPOSE With radiology practices increasingly employing nonphysician practitioners (NPPs), we aimed to characterize specific NPP clinical roles. METHODS Linking 2017 to 2019 Medicare data sets, we identified all claims-submitting nurse practitioners and physician assistants (together NPPs) employed by radiologists. NPP-billed services were identified, weighted by work relative value units, and categorized as (1) clinical evaluation and management (E&M), (2) invasive procedures, and (3) noninvasive imaging interpretation. NPP practice patterns were assessed temporally and using frequency analysis. RESULTS As the number of radiologist-employed NPPs submitting claims increased 16.3% (from 523 in 2017 to 608 in 2019), their aggregate Medicare fee-for-service work relative value units increased 17.3% (+40.0% for E&M [from 79,540 to 111,337]; +5.6% for procedures [from 179,044 to 189,003]; and +74.0% for imaging [from 5,087 to 8,850]). The number performing E&M, invasive procedures, and imaging interpretation increased 7.6% (from 329 to 354), 18.3% (from 387 to 458), and 31.8% (from 85 to 112), with 58.2%, 75.3%, and 18.4% billing those services in 2019. Paracentesis and thoracentesis were the most frequently billed invasive procedures. Fluoroscopic swallowing and bone densitometry examinations were the most frequently billed imaging services. By region, NPPs practicing as majority clinical E&M providers were most common in the Midwest (33.5%) and South (33.0%), majority proceduralists in the South (53.1%), and majority image interpreters in the Midwest (50.0%). CONCLUSIONS As radiology practices employ more NPPs, radiologist-employed NPPs' aggregate services have increased for E&M, invasive procedures, and imaging interpretation. Most radiologist-employed NPPs perform invasive procedures and E&M. Although performed by a small minority, imaging interpretation has shown the largest relative service growth.

Out-of-Pocket Expenditures for Imaging Examinations: Perspectives From National Patient Surveys Over Two Decades. J Am Coll Radiol 2023; 20:18-28. [PMID: 36210041 DOI: 10.1016/j.jacr.2022.07.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 07/20/2022] [Accepted: 07/30/2022] [Indexed: 11/06/2022]
Abstract
PURPOSE Using national surveys, we longitudinally studied imaging costs-and specifically those paid out-of-pocket (OOP) by patients-over two decades. METHODS Using 2000 to 2019 Medical Expenditure Panel Survey data, we identified all imaging-focused encounters (mammography, radiography, ultrasonography, and CT and MR [surveyed together in Medical Expenditure Panel Survey]) and calculated mean overall and OOP encounter costs. Effects of sociodemographic, personal, and clinical factors were measured using logistic regression and generalized linear modeling. RESULTS We identified 102,717 patients (mean 45.6 years; 64.8% female; 58.8% White) undergoing 229,010 imaging-focused encounters. Between 2000 and 2019, mean costs of mammography, radiography, and ultrasonography increased 14.5%, 24.5%, and 40% and total mean cost of CT or MR decreased by 15.1%. OOP costs were incurred by 51%. Overall mean OOP costs increased 89.8% from 2000 to 2019. Mean OOP costs for mammography decreased by 32.9%; mean OOP costs for radiography, ultrasonography, and CT or MR increased 81%, 123.2%, and 61%, respectively. Patients were less likely to incur OOP costs when older, of racial and ethnic minorities, female, or recipients of public only (versus private) insurance. Among those with OOP costs, the presence of comorbidities, lack of insurance, younger age, and history of cancer significantly increased OOP costs. CONCLUSION Mean overall patient OOP costs for imaging examinations increased significantly and substantially over the last two decades. Lack of insurance, younger age, history of cancer, and other comorbidities were associated with higher OOP costs. As diagnostic imaging utilization increases, patient financial hardship considerations merit further attention.

Abstract
Positron emission tomography (PET) integrated with computed tomography (CT) has brought revolutionary changes in improving cancer care (CC) for patients. These include improved detection of previously unrecognizable disease, ability to identify oligometastatic status enabling more aggressive treatment strategies when the disease burden is lower, its use in better defining treatment targets in radiotherapy (RT), ability to monitor treatment responses early and thus improve the ability for early interventions of non-responding tumors, and as a prognosticating tool as well as outcome predicting tool. PET/CT has enabled the emergence of new concepts such as radiobiotherapy (RBT), radioimmunotherapy, theranostics, and pharmaco-radiotherapy. This is a rapidly evolving field, and this primer is to help summarize the current status and to give an impetus to developing new ideas, clinical trials, and CC outcome improvements.

Abstract
IMPORTANCE The use of nonphysician practitioners (NPPs) in the emergency department (ED) continues to expand, yet little is known about associations between NPPs and ED imaging use. OBJECTIVE To investigate whether the state share of ED visits for which an NPP was the clinician of record is associated with imaging studies ordered, given that state NPP share is associated with state-level NPP scopes of practice. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study compared diagnostic imaging ordering patterns associated with ED visits based on 2005-2020 Medicare claims for a nationally representative 5% sample of fee-for-service beneficiaries. For all 50 states and the District of Columbia, the state NPP share of ED visits by year was used to represent state-specific practice patterns for NPPs and physicians and how those patterns have evolved over time. The analysis controlled for patient demographic characteristics, Charlson Comorbidity Index scores, ED visit severity, year, and principal diagnosis. EXPOSURES The share of ED visits in each state in each year (state share) for which an NPP was the evaluation and management clinician. MAIN OUTCOMES AND MEASURES The main outcomes were the number and modality of imaging studies associated with ED visits. Analyses were by logistic regression and generalized linear model with γ-distribution and log-link function. RESULTS Among 16 922 274 ED visits, 60.0% involved women, and patients' mean (SD) age was 70.3 (16.1) years. The share of all ED visits with an NPP as the clinician increased from 6.1% in 2005 to 16.6% in 2020. Compared with no NPPs, the presence of NPPs in the ED was associated with 5.3% (95% CI, 5.1%-5.5%) more imaging studies per ED visit, including a 3.4% (95% CI, 3.2%-3.5%) greater likelihood of any imaging order per ED visit and 2.2% (95% CI, 2.0%-2.3%) more imaging studies ordered per visit involving imaging. CONCLUSIONS AND RELEVANCE In this study, use of NPPs in the ED was associated with higher imaging use compared with the use of only physicians in the ED. Although expanded use of NPPs in the ED may improve patient access, the costs and radiation exposure associated with more imaging warrants additional study.

Abstract
Typically the creative product of the mind, intellectual property often forms the basis of a new product, service line, or company. Intellectual property law is complicated and nuanced, and poorly understood by many physicians, innovators, and entrepreneurs. Successfully navigating the process of intellectual property protection is critical in facilitating the translation of innovation into clinical practice. We define intellectual property and common terms used in intellectual property law and offer justification for the importance of intellectual property protections. We additionally highlight resources to assist radiologists with intellectual property protection and outline basic guidelines to successfully initiate discussions around intellectual property with third party vendors and consultants. SUMMARY: Proactive intellectual property protection is critically important for radiologist innovators seeking to bring new ideas to the marketplace.

Abstract
PURPOSE Radiologist medical school pathways have received little attention in recent workforce investigations. With osteopathic enrollment increasing, we assessed the osteopathic versus allopathic composition of the radiologist workforce. METHODS Linking separate Medicare Doctors and Clinicians Initiative databases and Physician and Other Supplier Files from 2014 through 2019, we assessed (descriptively and using multivariate panel logistic regression modeling) individual and practice characteristics of radiologists who self-reported medical degrees. RESULTS Between 2014 and 2019, as the number of osteopathic radiologists increased 46.0% (4.7% to 6.0% of total radiologist workforce), the number of allopathic radiologists increased 12.1% (representing a relative workforce decrease from 95.3% to 94.0%). For each year since completing training, practicing radiologists were 3.7% less likely to have osteopathic (versus allopathic) degrees (odds ratio [OR] = 0.96 per year, P < .01). Osteopathic radiologists were less likely to work in urban (versus rural) areas (OR = 0.95), and compared with the Midwest, less likely to work in the Northeast (OR = 0.96), South (OR = 0.95), and West (OR = 0.94) (all P < .01). Except for cardiothoracic imaging (OR = 0.78, P = .24), osteopathic radiologists were more likely than allopathic radiologists to practice as general (rather than subspecialty) radiologists (range OR = 0.37 for nuclear medicine to OR = 0.65 for neuroradiology, all P < .01). CONCLUSIONS Osteopathic physicians represent a fast-growing earlier-career component of the radiologist workforce. Compared with allopathic radiologists, they more frequently practice as generalist radiologists, in rural areas, and in the Midwest. Given recent calls for greater general and rural radiology coverage, increasing osteopathic representation in the national radiologist workforce could improve patient access.

Abstract
PURPOSE Previous studies have reported higher qualification characteristics for anesthesiologists, neurosurgeons, orthopedic surgeons, and otolaryngologists serving as defense (versus plaintiff) medical malpractice expert witnesses. We assessed such characteristics for radiologist expert witnesses. METHODS Using the Westlaw legal research database, we identified radiologists serving as experts in all indexed medical malpractice cases between 2010 and 2019. Online databases were used to identify years of practice experience and scholarly bibliometrics. Using Medicare claims, individual radiologist practice types and mixes were ascertained. Radiologists testifying at least once each for defense and plaintiff were excluded from our defense-only versus plaintiff-only comparative analysis. RESULTS Initial Boolean searches yielded 1,042 potential cases; subsequent manual review identified 179 radiologists testifying in 231 lawsuits: 143 testified in one case (58 defense, 85 plaintiff) and 36 testified in multiple cases (10 defense-only, 14 plaintiff-only, 12 both). The 68 defense-only experts had fewer years of practice experience than the 99 plaintiff-only experts (28.3 versus 31.8 years, P = .02), but the two groups were otherwise similar in both practice type (44.6% versus 54.9% academic, P = .62) and mix (63.8% versus 65.8% practiced as subspecialists, P = .37) and as well as numbers of publications (60.5 versus 62.8, P = .86), citations (1,994.1 versus 2,309.2, P = .56), and h-indices (17.2 versus 16.8, P = .89). CONCLUSIONS In contrast to other specialists, radiologists serving as medical malpractice expert witnesses for defense and plaintiff display similar qualifications across various characteristics. Published practice parameter guidelines and experts' ability to blindly review archived original images might together explain this interspecialty discordance.

Abstract
RATIONALE AND OBJECTIVES While radiology training programs aim to prepare trainees for clinical practice, the relationship between trainee, and national radiology workforce demands is unclear. This study assesses changing radiology trainee neuroimaging workloads nationwide for neuroimaging studies. MATERIALS AND METHODS Using aggregate Medicare claims files from 2002 to 2018, we identified all computed tomography (CT) and magnetic resonance (MR) examinations of the brain, head and neck, and spine (hereafter "neuroimaging") in Medicare fee-for-service beneficiaries nationwide. Using separate Medicare files, we calculated population utilization rates, and work relative value unit (wRVU) weights of all diagnostic neuroradiology services. Using claims modifiers, we identified services rendered by radiology trainees. Using separate national trainee enrollment files, we calculated mean annual per trainee wRVUs. RESULTS Between 2002 and 2018, total Medicare neuroimaging claims increased for both radiologists overall (86.1%) and trainees (162.5%), including increases in both CT (102.9% vs 196.8%), and MR (59.9% vs 106.6%). The national percentage of all radiologist neuroimaging wRVUs rendered by trainees increased 46.1% (3.8% of all wRVUs nationally in 2002 to 5.6% in 2018). National trainee increases were present across all neuroimaging services but greatest for head and neck CT (+86.5%). Mean annual per radiology trainee neuroimaging Medicare wRVUs increased +174.9% (42.1 per trainee in 2002 to 115.70 in 2018). Mean per trainee wRVU increases were greatest for spine CT (+394.2%) but present across all neuroimaging services. CONCLUSION As neuroimaging utilization in Medicare beneficiaries has grown, radiology trainee neuroimaging workloads have increased disproportionately.

Abstract
PURPOSE Emerging price transparency tools allow consumers to access individualized out-of-pocket cost (OOPC) estimates, but many lack quality metrics. The aim of this study was to evaluate how potential patients weigh imaging OOPC versus measures of quality when selecting an imaging center for a hypothetical health condition (back pain). METHODS Surveying 1,310 Amazon Mechanical Turk volunteers, the authors evaluated how potential patients weigh MRI OOPC ($50 vs $400 vs unknown cost at the time of the examination, with billed OOPC responsibility varying between $50 and $3,500) versus service quality surrogates using three different quality indicators (examination results accuracy, physician recommendation of an imaging center on the basis of familiarity, and facility online star ratings) in their decisions when selecting a radiology center for imaging of two hypothetical clinical conditions (mild and severe back pain), using ranking-based conjoint analyses. RESULTS A total of 1,025 eligible respondents completed the survey. Respondents expressed higher preference for perceived quality over cost in hypothetical severe back pain scenarios, resulting in a relative importance of 65.8% (95% confidence interval [CI], 62.2%-69.4%) for improved imaging results accuracy from 87% to 96%, 63.9% (95% CI, 60.3%-67.5%) for provider recommendations of the facility, and 80.1% (95% CI, 74.2%-85.9%) for an increase in online review star ratings from 2.5 to 4.5 (out of 5) compared with an increased cost from $50 to $400. For mild back pain, there was no statistical difference in respondents' preference for perceived quality and cost. CONCLUSIONS Incorporating quality metrics into price transparency tools is important. Further research is needed to identify metrics that are most comparable and easily obtainable across imaging centers that remain important to patients.

National Utilization, Survival, and Costs Analysis of Treatment Options for Stage I Non-Small Cell Lung Cancer: A SEER-Medicare Database Analysis. Acad Radiol 2022; 29 Suppl 2:S173-S180. [PMID: 34404607 DOI: 10.1016/j.acra.2021.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 07/07/2021] [Accepted: 07/16/2021] [Indexed: 11/01/2022]
Abstract
RATIONALE AND OBJECTIVES To compare utilization, outcomes, and costs of surgery, radiation therapy, and percutaneous ablation for the treatment of stage I non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Using 2006-2016 Medicare-linked Surveillance, Epidemiology, and End Results (SEER) databases, stage I NSCLC patients who underwent surgery, radiotherapy, or percutaneous ablation were identified using relevant billing codes. National utilization rates were determined. Overall survival for treatment arms were compared using log-rank test and Cox-proportional hazard modeling. Mean direct costs for each treatment strategy during the first year after diagnosis were compared using Analysis of Variance. RESULTS A total of 15,847 Stage I NSCLC patients were identified; mean age at diagnosis was 75.5 years (minimum age = 66 years) and 59.2% were female. A total of 10,732 patients (67.7%) underwent only surgery, 5013 (31.6%) only radiotherapy, and 102 (0.6%) only ablation. Utilization of surgery and ablation decreased while radiotherapy utilization increased from 2007 to 2015 (p < 0.0001). Compared to the ablation group, overall survival was greater for the surgery group (HR: 0.7, 95% CI of HR: 0.6-0.9, p = 0.0047) and lower for the radiotherapy group (HR: 1.4, 95% CI of HR: 1.1-1.8, p = 0.002). The mean first year cost of therapy for ablation = $11,976) was significantly less (p < 0.05) than for radiotherapy ($15,447) and surgery ($22,669). CONCLUSION In Medicare patients with stage I NSCLC, the utilization of radiation therapy has increased and surgery has declined, while utilization of percutaneous ablation has remained uniformly low. Although overall survival is best for surgery, then ablation, and then radiation therapy, first year treatment costs are lowest for ablation.

COVID-19 Pandemic-Associated Changes in the Acuity of Brain MRI Findings: A Secondary Analysis of Reports Using Natural Language Processing. Curr Probl Diagn Radiol 2021; 51:529-533. [PMID: 34955284 PMCID: PMC8636309 DOI: 10.1067/j.cpradiol.2021.11.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 11/15/2021] [Accepted: 11/28/2021] [Indexed: 11/22/2022]
Abstract
Rationale and Objectives We aimed to assess early COVID-19 pandemic-associated changes in brain MRI examination frequency and acuity of imaging findings acuity. Methods Using a natural language processing model, we retrospectively categorized reported findings of 12,346 brain MRI examinations performed during 6-month pre-pandemic and early pandemic time periods across a large metropolitan health system into 3 acuity levels: (1) normal or near normal; (2) incidental or chronic findings not requiring a management change; and (3) new or progressive findings requiring a management change. Brain MRI frequency and imaging finding acuity level were compared over time. Results Between March and August of 2019 (pre-pandemic) and 2020 (early pandemic), our health system brain MRI examination volumes decreased 17.0% (6745 vs 5601). Comparing calendar-matched 6-month periods, the proportion of higher acuity findings increased significantly (P< 0.001) from pre-pandemic (22.5%, 43.6% and 34.0% in acuity level 1, 2, and 3, respectively) to early pandemic periods (19.1%, 40.9%, and 40.1%). During the second 3 months of the early pandemic period, as MRI volumes recovered to near baseline, the proportion of higher acuity findings remained high (42.6% vs 34.1%) compared with a similar pre-pandemic period. In a multivariable analysis, Black (B coefficient, 0.16) and underinsured population (B coefficient, 0.33) presented with higher acuity findings (P< 0.05). Conclusions As the volume of brain MRI examinations decreased during the early COVID-19 pandemic, the relative proportion of examinations with higher acuity findings increased significantly. Pandemic-related changes in patient outcomes related to reduced imaging access merits further attention.

Abstract
IMPORTANCE Prostate cancer screening and diagnosis exhibit known racial and ethnic disparities. Whether these disparities persist in prostate magnetic resonance imaging (MRI) utilization after elevated prostate-specific antigen (PSA) results is poorly understood. OBJECTIVE To assess potential racial and ethnic disparities in prostate MRI utilization following elevated PSA results. DESIGN, SETTING, AND PARTICIPANTS This cohort study of 794 809 insured US men was drawn from deidentified medical claims between January 2011 and December 2017 obtained from a commercial claims database. Eligible participants were aged 40 years and older and received a single PSA result and no prior PSA screening or prostate MRI claims. Analysis was performed in January 2021. MAIN OUTCOMES AND MEASURES Multivariable logistic regression was used to examine associations between elevated PSA results and follow-up prostate MRI. For patients receiving prostate MRI, multivariable regressions were estimated for the time between PSA and subsequent prostate MRI. PSA thresholds explored included PSA levels above 2.5 ng/mL, 4 ng/mL, and 10 ng/mL. Analyses were stratified by race, ethnicity, and age. RESULTS Of 794 809 participants, 51 500 (6.5%) had PSA levels above 4 ng/mL; of these, 1524 (3.0%) underwent prostate MRI within 180 days. In this sample, mean (SD) age was 59.8 (11.3) years (range 40-89 years); 31 350 (3.9%) were Asian, 75 935 (9.6%) were Black, 107 956 (13.6%) were Hispanic, and 455 214 (57.3%) were White. Compared with White patients, Black patients with PSA levels above 4 ng/mL and 10 ng/mL were 24.1% (odds ratio [OR], 0.78; 95% CI, 0.65-0.89) and 35.0% (OR, 0.65; 95% CI, 0.50-0.85) less likely to undergo subsequent prostate MRI, respectively. Asian patients with PSA levels higher than 4 ng/mL (OR, 0.76; 95% CI, 0.58-0.99) and Hispanic patients with PSA levels above 10 ng/mL (OR, 0.77; 95% CI, 0.59-0.99) were also less likely to undergo subsequent prostate MRI compared with White patients. Black patients between ages 65 and 74 years with PSA above 4 ng/mL and 10 ng/mL were 23.6% (OR, 0.76; 95% CI, 0.64-0.91) and 43.9% (OR, 0.56; 95% CI, 0.35-0.91) less likely to undergo MRI, respectively. Race and ethnicity were not significantly associated with mean time between PSA and MRI. CONCLUSIONS AND RELEVANCE Among men with elevated PSA results, racial and ethnic disparities were evident in subsequent prostate MRI utilization and were more pronounced at higher PSA thresholds. Further research is needed to better understand and mitigate physician decision-making biases and other potential sources of disparities in prostate cancer diagnosis and management.

Management of Splenic Trauma in Contemporary Clinical Practice: A National Trauma Data Bank Study. Acad Radiol 2021; 28 Suppl 1:S138-S147. [PMID: 33288400 DOI: 10.1016/j.acra.2020.11.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Revised: 11/11/2020] [Accepted: 11/12/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND To evaluate the utilization and efficacy of various treatments for management of adult patients with splenic trauma, highlighting the evolving role of splenic artery embolization. MATERIALS AND METHODS The National Trauma Data Bank (NTDB) was queried for patients who sustained splenic trauma between 2007 and 2015, excluding those with death on arrival and selected nonsplenic high-grade injuries. Patients were categorized into (1) nonoperative management (NOM), (2) embolization, (3) splenectomy, (4) splenic repair, and (5) combined treatment groups. Evaluated outcomes included hospital length of stay (LOS), intensive care unit LOS, mortality, and NOM and embolization failures. RESULTS Overall, 117,743 patients with splenic predominant trauma were included in this study. Over the 9-year study period, 85,793 (72.9%) were treated with NOM, 21,999 (18.9%) with splenectomy, 3895 (3.3%) with embolization, and 2131 (1.8%) with splenic repair. From 2007 to 2015, mortality rates declined from 7.6% to 4.7%. The rate of NOM did not significantly change over time, while embolization increased 369% (1.3%-4.8%). Failure of NOM was 4.4% in 2007 and decreased to 3.4% in 2015. Across all injury grades, NOM had the shortest LOS (8.3 days), followed by splenic repair (12.3), embolization (12.6), and splenectomy (13.8) (p < 0.001). When adjusted for various clinical factors including severity of splenic injury, mortality rates were 7.1% for splenectomy, 3.2% for embolization, and 2.5% for NOM. CONCLUSION Most patients with splenic-dominant blunt trauma are managed with NOM. Over time, the use of embolization has increased while open surgery has declined, and mortality has improved for all treatment methods. Compared to splenectomy, embolization is associated with shorter hospital LOS but is still used relatively infrequently.

Trends and variations in utilization and costs of radiotherapy for prostate cancer: A SEER medicare analysis from 2007 through 2016. Brachytherapy 2021; 21:12-21. [PMID: 34380592 DOI: 10.1016/j.brachy.2021.06.148] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 06/15/2021] [Accepted: 06/24/2021] [Indexed: 11/02/2022]
Abstract
OBJECTIVE To assess recent changes and disparities in utilization and costs of radiotherapy in Medicare beneficiaries with prostate cancer. METHODS Surveillance, Epidemiology and End Results (SEER) -Medicare linked data from 2006-2016 were used to identify continuously enrolled Medicare beneficiaries with a first-time diagnosis of prostate cancer who, within 12 months of diagnosis, underwent at least one radiotherapy related service. Trends in the utilization of different radiotherapy techniques over time, yearly changes in per-patient costs of radiotherapy, and effect of socio-demographic and clinical characteristics on total cost were measured. Per patient annual costs, annual incidence of prostate cancer, and utilization of radiotherapy were used to estimate total costs of radiotherapy to the Medicare program. RESULTS For Medicare beneficiaries with a first-time diagnosis of prostate cancer, the utilization of intensity modulated radiation therapy (IMRT), proton therapy, and stereotactic body radiation therapy (SBRT) increased 23.62%, 0.74% and 1.61% respectively (p <0.0001) while brachytherapy decreased 17.04% (p <0.0001). Cost per beneficiary decreased $340.24 (95% CI: $136.05 - $544.43) annually (p = 0.0065). Age, registry region, and Gleason score were all associated with expenditures. The total cost to the Medicare program was estimated at US $1.16 billion in the year 2016. DISCUSSION In Medicare beneficiaries with prostate cancer treated with radiotherapy, IMRT is the primary mode of treatment. Utilization of brachytherapy decreased significantly despite the efficacy and cost-effectiveness. Although per patient costs have decreased, the share of patient responsibility remained unaltered across years. The current costs to Medicare of radiotherapy for newly diagnosed prostate cancer patients is substantial.

Comparing the Safety and Cost of Image-Guided Percutaneous Gastrostomy Tube Placement in the Outpatient Versus Overnight Observation Setting in a Single-Center Retrospective Study. Acad Radiol 2021; 28:1081-1085. [PMID: 32527708 DOI: 10.1016/j.acra.2020.04.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Revised: 04/19/2020] [Accepted: 04/23/2020] [Indexed: 10/24/2022]
Abstract
RATIONALE AND OBJECTIVES Historically, patients undergoing image-guided percutaneous gastrostomy tube placement have been admitted overnight with feeds commencing 12-24 hours postprocedure. With new expedited feeding protocols starting 3-4 hours postprocedure, same-day discharge is now possible. The purpose of this study was to evaluate the safety and cost of image-guided percutaneous gastrostomy tube placement as an outpatient procedure. MATERIALS AND METHODS In this retrospective study, 131 patients (age 63.9 ± 11.6; 34% female) underwent gastrostomy tube placement as an outpatient procedure with expedited feeding protocol versus 40 patients (age 61.3 ± 12.6; 38% female) who were hospitalized overnight with feeds starting at 12-24 hours, primarily based on operator preference. The two groups were compared regarding complications within 90 days of procedure. Using a subgroup of 33 consecutive patients, procedural costs (total combined insurer and patient payments for professional and hospital services) for outpatients vs. hospitalized patients were compared. RESULTS Complication rates were similar (p = 0.64) for gastrostomy tubes placed on outpatients (0.17 complications/procedure: 4 bleeding, 2 aspiration pneumonia, 1 abdominal abscess, 4 significant pain, 6 cellulitis, 1 surgical consult, 4 malpositioned/fractured tubes) and hospitalized patients (0.20 complications/procedure: 1 aspiration pneumonia, 1 significant pain, 3 cellulitis, 1 surgical consult, 2 fractured tubes). Total combined insurer and patient payments were similar ($2193/outpatient vs $2701/hospitalized patient; p= 0.52). CONCLUSION Outpatient image-guided percutaneous gastrostomy tube placement with an expedited feeding protocol is a safe and cost-comparable alternative to historic overnight hospitalization. Further prospective investigation with a larger sample is warranted.

Secondary Interpretations of Diagnostic Imaging Examinations: Patient Liabilities and Out-of-Pocket Costs. J Am Coll Radiol 2021; 18:1547-1555. [PMID: 34293329 DOI: 10.1016/j.jacr.2021.07.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Revised: 07/01/2021] [Accepted: 07/02/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Secondary interpretations of diagnostic imaging examinations are increasingly performed to improve care for complex patients. We sought to determine associated patient-billed liabilities and out-of-pocket payments and to identify patient and imaging study characteristics that correlate with higher patient bills and out-of-pocket payments. METHODS Data extracted for 7,740 secondary imaging interpretations performed across our large metropolitan health system over 25 months included total professional charges, insurance payments, patient-billed liabilities, and patient out-of-pocket payments. Multivariable linear regression analyses were performed to identify patient and imaging factors associated with higher patient bills and out-of-pocket payments. RESULTS Mean secondary interpretation professional charges, insurance payments, patient-billed liabilities, and patient out-of-pocket payments were $306.50, $108.02, $27.80, and $14.55, respectively. Patients received bills for 47.5% of services and made out-of-pocket payments for 17.1%. Patient-billed liabilities and out-of-pocket payments were higher for patients who were younger and uninsured and for secondary interpretations requested for patients seen in outpatient (versus inpatient) settings. Patient-billed liabilities and out-of-pocket payments were lower for patients who were Black (versus White) and had government-sponsored (versus commercial) insurance and for secondary interpretations performed during the second, third, or fourth (versus first) quarter of each calendar year. CONCLUSION Observed differences between patient-billed liabilities and out-of-pocket payments suggest that secondary interpretations of diagnostic imaging examinations can result in small but real patient financial burdens. Improved price transparency and enhanced patient communication about the value of secondary interpretations could reduce potential surprises when patients receive these bills.

Federal Out-of-Network Balance Billing Legislation: Context and Implications for Radiology Practices. Radiology 2021; 300:506-511.

Abstract
Out-of-network (OON) balance billing, commonly known as surprise billing but better described as a surprise gap in health insurance coverage, occurs when an individual with private health insurance (vs a public insurer such as Medicare) is administered unanticipated care from a physician who is not in their health plan's network. Such unexpected OON care may result in substantial out-of-pocket costs for patients. Although ending surprise billing is patient centric, patient protective, and noncontroversial, passing federal legislation was challenging given its ability to disrupt insurer-physician good-faith negotiations and thus impact in-network rates. Like past proposals, the recently passed No Surprises Act takes patients out of the middle of insurer-physician OON reimbursement disputes, limiting patients' expense to standard in-network cost-sharing amounts. The new law, based on arbitration, attempts to protect good-faith negotiations between physicians and insurance companies and encourages network contracting. Radiology practices, even those that are fully in network or that never practiced surprise billing, could nonetheless be affected. Ongoing rulemaking processes will have meaningful roles in determining how the law is made operational. Physician and stakeholder advocacy has been and will continue to be crucial to the ongoing evolution of this process. © RSNA, 2021.

Abstract
INTRODUCTION The Affordable Care Act of 2010 mandated private health plans to fully cover the services recommended by the U.S. Preventive Services Task Force. In June 2016, the Task Force added computed tomography colonography to its list of recommended tests for colorectal cancer screening. This study evaluates the association among the updated recommendation, patient cost-sharing obligations, and the uptake of colorectal cancer screening through computed tomography colonography in the privately insured population. METHODS Using individual claims from the 2010-2018 IBM MarketScan Commercial Database, monthly screening computed tomography colonography utilization rates per 100,000 privately insured beneficiaries aged 50-64 years and the monthly proportions of these services delivered by in-network providers for which patients had to bear a portion of the procedure costs were calculated, and an interrupted time series analysis was performed. The study was conducted between January and May 2020. RESULTS Although the proportion of in-network procedures subject to patient cost sharing declined from 38.2% in 2010 to 10.2% in early 2016, the monthly utilization remained nearly constant. The announcement of the updated recommendation was associated with an immediate increase in the monthly screening computed tomography colonography utilization rate from 0.4 to 0.6 procedures per 100,000 individuals but with no change in the proportion of in-network procedures subject to patient cost sharing. CONCLUSIONS In an environment of already largely eliminated patient cost sharing, the release of supportive evidence-based recommendations by a recognized credible body was associated with an immediate increase in computed tomography colonography use for colorectal cancer screening in the privately insured population.

Abstract
Background Factors affecting radiologists' performance in screening mammography interpretation remain poorly understood. Purpose To identify radiologists characteristics that affect screening mammography interpretation performance. Materials and Methods This retrospective study included 1223 radiologists in the National Mammography Database (NMD) from 2008 to 2019 who could be linked to Centers for Medicare & Medicaid Services (CMS) datasets. NMD screening performance metrics were extracted. Acceptable ranges were defined as follows: recall rate (RR) between 5% and 12%; cancer detection rate (CDR) of at least 2.5 per 1000 screening examinations; positive predictive value of recall (PPV1) between 3% and 8%; positive predictive value of biopsies recommended (PPV2) between 20% and 40%; positive predictive value of biopsies performed (PPV3) between the 25th and 75th percentile of study sample; invasive CDR of at least the 25th percentile of the study sample; and percentage of ductal carcinoma in situ (DCIS) of at least the 25th percentile of the study sample. Radiologist characteristics extracted from CMS datasets included demographics, subspecialization, and clinical practice patterns. Multivariable stepwise logistic regression models were performed to identify characteristics independently associated with acceptable performance for the seven metrics. The most influential characteristics were defined as those independently associated with the majority of the metrics (at least four). Results Relative to radiologists practicing in the Northeast, those in the Midwest were more likely to achieve acceptable RR, PPV1, PPV2, and CDR (odds ratio [OR], 1.4-2.5); those practicing in the West were more likely to achieve acceptable RR, PPV2, and PPV3 (OR, 1.7-2.1) but less likely to achieve acceptable invasive CDR (OR, 0.6). Relative to general radiologists, breast imagers were more likely to achieve acceptable PPV1, invasive CDR, percentage DCIS, and CDR (OR, 1.4-4.4). Those performing diagnostic mammography were more likely to achieve acceptable PPV1, PPV2, PPV3, invasive CDR, and CDR (OR, 1.9-2.9). Those performing breast US were less likely to achieve acceptable PPV1, PPV2, percentage DCIS, and CDR (OR, 0.5-0.7). Conclusion The geographic location of the radiology practice, subspecialization in breast imaging, and performance of diagnostic mammography are associated with better screening mammography performance; performance of breast US is associated with lower performance. ©RSNA, 2021 Online supplemental material is available for this article.

Comparison of Radiologists and Other Specialists in the Performance of Lumbar Puncture Procedures Over Time. AJNR Am J Neuroradiol 2021; 42:1174-1181. [PMID: 33664117 DOI: 10.3174/ajnr.a7049] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Accepted: 11/26/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE Lumbar punctures may be performed by many different types of health care providers. We evaluated the percentages of lumbar punctures performed by radiologists-versus-nonradiologist providers, including changes with time and discrepancies between specialties. MATERIALS AND METHODS Lumbar puncture procedure claims were identified in a 5% sample of Medicare beneficiaries from 2004 to 2017 and classified by provider specialty, site of service, day of week, and patient complexity. Compound annual growth rates for 2004 versus 2017 were calculated; t test and χ2 statistical analyses were performed. RESULTS Lumbar puncture use increased from 163.3 to 203.4 procedures per 100,000 Medicare beneficiaries from 2004 to 2017 (overall rate, 190.3). Concurrently, the percentage of lumbar punctures performed by radiologists increased from 37.1% to 54.0%, while proportions performed by other major physician specialty groups either declined (eg, neurologists from 23.5% to 10.0%) or were largely unchanged. While radiologists saw the largest absolute increase in the percentage of procedures, the largest relative increase occurred for nonphysician providers (4.2% in 2004 to 7.5% in 2017; +78.6%). In 2017, radiologists performed most procedures on weekdays (56.2%) and a plurality on weekends (38.2%). Comorbidity was slightly higher in patients undergoing lumbar puncture by radiologists (P < .001). CONCLUSIONS Radiologists now perform most lumbar puncture procedures for Medicare beneficiaries in both the inpatient and outpatient settings. The continuing shift in lumbar puncture responsibility from other specialists to radiologists has implications for clinical workflows, cost, radiation exposure, and postgraduate training.
