Which health conditions report the most spending on medical imaging? Evidence for Colombia.

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.

Contemporary Management of Blunt Splenic Trauma in Adults: An Analysis of the Trauma Quality Improvement Program Registry.

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.

Scanners, schedules, and statutes: A tale of trauma, policy, and profit.

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.

Radiology residency oversight: A Qui Tam wake-up call.

Like every physician practice, academic radiology practices must pay heed to all governmental regulations. The federal False Claims Act serves to protect US taxpayers and requires strict adherence. Violations, often brought forth by whistleblowers, can carry steep financial repercussions.

The 2021 ACR/RBMA Workforce Survey: Practice Types, Employment Trends, and Hiring Needs.

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.

Financial Impact of Imaging Examination Site of Service in the Medicare Population.

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.

Influential Radiology Figures and Organizations in Social Media.

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.

Are Academic Emergency Radiologists Systematically Disadvantaged Compared With Diagnostic Radiology Subspecialty Counterparts When It Comes to Promotion?

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.

An Examination of Racial and Ethnic Disparities in the Use of Prostate Biopsy and Magnetic Resonance Imaging in Prostate Cancer Screening.

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.

Trends in Diagnostic Imaging by Nonphysician Practitioners and Associations With Urbanicity and Scope-of-Practice Authority.

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.

Contemporary Management of Blunt Liver Trauma: An Analysis of the Trauma Quality Improvement Program Registry (2007-2019).

PURPOSE: To evaluate the effectiveness of management strategies for blunt liver injuries in adult patients. MATERIALS AND METHODS: Patients aged ≥18 years with blunt liver injuries registered via the Trauma Quality Improvement Program (2007-2019) were identified. Management strategies initiated within 24 hours of hospital presentation were classified as nonoperative 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% underwent NOM, surgery, embolization, and combination therapy, respectively. Among patients with low-grade (n = 62,237) and high-grade (n = 15,890) injuries and compared with all other management strategies, NOM was associated with the shortest hospital LOS and ICU LOS. Among patients with low-grade injuries and compared with surgery, embolization was associated with a shorter hospital LOS (9.7 days; P < .001; Cohen d = 0.32) and ICU LOS (5.3 days; P < .001; Cohen d = 0.36). Among patients with high-grade injuries and compared with surgery, embolization was associated with a shorter ICU LOS (6.0 days; P < .01; Cohen d = 0.24). Among patients with low- and high-grade injuries and compared with embolization, surgery was associated with higher odds of mortality (P < .001). CONCLUSIONS: Among patients presenting with blunt liver injuries and compared with surgery, embolization was associated with a shorter ICU LOS and lower risk of mortality.

Use of Metformin and Survival in Patients with Hepatocellular Carcinoma (HCC) Undergoing Liver Directed Therapy: Analysis of a Nationwide Cancer Registry.

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.

Use and Cost of Skin Biopsy Procedures in the Medicare Part B Fee-for-Service Population, 2017 to 2020.

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.

Comparison of Lung Cancer Screening Eligibility and Use between Commercial, Medicare, and Medicare Advantage Enrollees.

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.

Out-of-Pocket Expenditures for Imaging Examinations: Perspectives From National Patient Surveys Over Two Decades.

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.

Recent trends in high-volume Medicare stroke thrombectomy provider characteristics.

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.

Association and Trends in Medicare Denials and Utilization for Brain CT: Indirect Impacts by Targeted Policy Intervention?

Twenty-five years of annual Medicare Physician/Supplier Procedure Summary (PSPS) Master File data were used to assess trends in normalized volume and claim denial rates for brain computerized tomography. Alongside growth in utilization of brain computerized tomography (services, denial rates, fell from 1999-2005 and with relatively leveled growth and less denial rate volatility thereafter. More recent trends in denial rates may be related to policy interventions initially aimed at cost and volume reduction.
