Referring physicians' attitudes toward international interpretation of teleradiology images.

OBJECTIVE: We evaluated referring physician attitudes toward the international interpretation of radiologic images. MATERIALS AND METHODS: A five-question, scenario-based survey describing features of a hypothetic local radiology firm compared with those of its hypothetic overseas counterpart, international radiology, was sent by mail to 350 physicians from a broad range of medical and surgical specialties. One hundred nineteen physicians responded, for a response rate of 34%. Referring physicians were asked to indicate their preference for local versus international interpretation in each scenario using a 5-point Likert scale, with a score of -2 indicating a strong preference for international services, 0 indicating no preference, and 2 indicating a strong preference for local services. RESULTS: When all variables are held to be equal, referring physicians strongly prefer local services (mean score, 1.77; SD, 0.77). When international teleradiology provides either a 2-day faster turnaround time for reports or a 30 dollars lower out-of-pocket cost to the patient, referring physicians still prefer local services, although less than they did with all variables held equal (mean score, 0.42-0.44; SD, 1.30-1.40). When international teleradiology provides both a 2-day faster turnaround time and a 30 dollars lower out-of-pocket cost to the patient, referring physicians preferred international teleradiology, albeit only slightly (mean, -0.25; SD, 1.50). Finally, when the credentials of the international radiologists are perceived to be less than those of the local radiologists, even in the face of faster turnaround time and 30 dollars lower cost to the patient, referring physicians overall strongly prefer local services (mean, 1.51; SD, 0.86). CONCLUSION: Referring physicians prefer local interpretation of radiologic images to international interpretation when all things are equal. However, the timeliness of image interpretation and the cost to the patient are important factors in this decision.

Residency training as technology matures a survey of radiology residents' training experiences.

RATIONALE AND OBJECTIVES: The aim of the study is to assess radiology resident training experience in cardiac magnetic resonance imaging (MRI), positron emission tomography (PET), obstetrical (OB) ultrasound (US), carotid US, and barium esophagram. MATERIALS AND METHODS: One hundred eighteen radiology residents completed surveys. Surveys assessed resident year of residency training, hospital size, program affiliation with an academic institution, state, performance of the examinations listed, number of examinations performed per week, and number of weeks spent on rotations for each modality. The study was approved by the institutional review board and was Health Insurance Portability and Accountability Act (HIPAA) compliant. t-Test and chi-square test were performed, and results were analyzed for statistical significance. RESULTS: Most (94 respondents; 80%) respondents were third-year residents, 101 residents (86%) stated their program was affiliated with an academic institution, 92 residents (78%) performed cardiac MRI, 104 (88%) performed PET, 84 (71%) performed OB US, 71 (60%) performed carotid US (one did not respond), and all performed esophagrams (although one did not respond). Only performance of cardiac MRI and PET correlated positively with a larger average hospital size (P < .01). Residents at an academically affiliated program were significantly more likely to perform cardiac MRI (P < .05). Geographic region significantly affected likelihood of performance of cardiac MRI only. CONCLUSION: Such factors as hospital size, academic institution affiliation, and geography affect radiology resident training, particularly for such maturing applications as cardiac MRI and PET. This information may be useful in attempts to standardize radiology residency training.

What characterizes academic radiology departments that secure large amounts of external funding for research?

RATIONALE AND OBJECTIVES: We sought to identify factors associated with high levels of external research funding in order to provide departments with information that may help them increase their external research funding. MATERIALS AND METHODS: National Institutes of Health (NIH) data on grants were analyzed to identify the 72 radiology departments receiving funds for diagnostic radiology research. A survey was sent to these departments. We placed them into one of three categories according to total NIH funds to the department. The survey asked about department characteristics such as size; breakdown of full-time faculty among MDs, MD/PhDs, and PhDs; research space; equipment type; and number and types of trainees. RESULTS: Thirty-nine surveys were returned, including 20 from the 21 departments with the most NIH funding. PhDs played a larger role in the most research funding-intensive departments than in others. These departments also were more likely than others to give protected time to all MDs and to devote over 5% of clinical revenues to research, and they had a lower clinical workload per MD. NIH was the source of 70% of their research funding, The role of MD/PhDs and research space per 1000 research dollars did not vary by research intensity. CONCLUSIONS: These findings only demonstrate associations; they do not show the direction of causality. Nonetheless, they suggest what departments need to do if they wish to increase their external research funding.

Is the tobacco settlement constitutional?

In August 2005, the Competitive Enterprise Institute (CEI), a conservative advocacy organization, filed a lawsuit in Louisiana challenging the legality of the 1998 Master Settlement Agreement (MSA). The suit alleges that the MSA, under which the states receive monetary payments and the four major tobacco companies are insulated from price competition, violates the Compact Clause and other provisions of the U.S. Constitution. This lawsuit threatens to unravel of one of the most significant opportunities to improve public health in United States history. We consider the merits of the lawsuit, the problems with the MSA that it highlights, and the potential consequences of the suit for public health.

Radiation dose associated with unenhanced CT for suspected renal colic: impact of repetitive studies.

OBJECTIVE: The purpose of our study was to assess the dose of ionizing radiation delivered through the use of unenhanced CT for suspected renal colic by determining the incidence of repeated unenhanced CT examinations and the cumulative radiation dose delivered. MATERIALS AND METHODS: All unenhanced CT examinations for suspected renal colic performed at our institution over a 6-year period were included, and patient age, sex, and multiplicity of examinations were determined. For the adult patient, this protocol prescribes a fixed tube current of 200 mA, 140 kVp, and a nominal slice width of 5 mm. The dose-length product (DLP) was estimated for 15 randomly chosen single-detector CT (SDCT) and MDCT adult flank pain examinations using manufacturer's software. The mean DLPs for SDCT and MDCT were computed and converted to effective doses. Total effective doses were calculated for patients who underwent more than three examinations, and values were compared with established standards. RESULTS: A total of 5,564 examinations were performed on 4,562 patients. Of these patients, 2,795 (61%) were women (mean age, 45.5 +/- 16.2 [SD] years) and 1,731 (38%) were men (mean age, 44.7 +/- 16.4 years), with 144 patients (3%) of pediatric age. The mean effective doses for a single study were 6.5 mSv for SDCT and 8.5 mSv for MDCT. A subset of 176 patients (4%) had three or more examinations, with estimated effective doses ranging from 19.5 to 153.7 mSv. All patients with multiple examinations had a known history of nephrolithiasis. CONCLUSION: Patients with a history of nephrolithiasis and flank pain are at increased risk for serial CT with potentially high cumulative effective doses.

Diagnostic CT scans: institutional informed consent guidelines and practices at academic medical centers.

OBJECTIVE: The purpose of this article is to characterize current informed consent practices for diagnostic CT scans at U.S. academic medical centers. MATERIALS AND METHODS: We surveyed 113 radiology chairpersons associated with U.S. academic medical centers using a survey approved by our institutional review board. The need for informed consent for this study was waived. Chairpersons were asked if their institutions have guidelines for nonemergent CT scans (by whom; oral and/or written), if patients are informed of the purpose of their scans (by whom), what specific risks are outlined (allergic reaction, radiation risk and dose, others; by whom), and if patients are informed of alternatives to CT. RESULTS: The study response rate was 81% (91/113). Of the respondents, two thirds (60/90) currently have guidelines for informed consent regarding CT scans. Radiology technologists were most likely to inform patients about CT (38/60, 63%) and possible risks (52/91, 57%), whereas ordering physicians were most likely to inform patients about CT's purpose (37/66, 56%). Fifty-two percent (30/58) of sites provided verbal information and 5% (3/58) provided information in written form. Possible allergic reaction to dye was explained at 84% (76/91) of sites, and possible radiation risk was explained at 15% (14/91) of sites. Nine percent (8/88) of sites informed patients of alternatives to CT. CONCLUSION: Radiology technologists are more likely to inform patients about CT and associated risks than their physician counterparts. Although most academic medical centers currently have guidelines for informed consent regarding CT, only a minority of institutions inform patients about possible radiation risks and alternatives to CT.

Update on the diagnostic radiology employment market: findings through 2005.

OBJECTIVE: The purpose of this study is to analyze and summarize the latest data describing the diagnostic radiologist employment market. MATERIALS AND METHODS: Three sources of data--vacancies in academic radiology departments as of July 1, 2005; the ratio of job listings to job seekers at a major placement service; and the number of positions advertised in the American Journal of Roentgenology and Radiology-are presented and compared with previous data. RESULTS: Vacancies in academic departments averaged 4.5 in 2005, an increase of 16% from 2004 but a decrease of 16% from the 2001 peak. Vacancies increased from 2004 in all specialties except nuclear medicine and "other," and vacancies decreased from 2001 in all specialties except pediatric radiology and purely research positions. Job listings per job seeker increased 8% from 2004 but remain far below peak levels. The total number of positions advertised decreased by 6% from 2004, reaching the lowest level since 1998. In 2005, 42% of the total advertised jobs were academic, as compared with 45% in 2004. Proportional decreases were seen between 2004 and 2005 in total advertisements per region except the Northwest and California. The largest proportional increases in subspecialties occurred in general radiology, abdominal imaging, and "other." CONCLUSION: Data from the American College of Radiology Professional Bureau and a survey of academic radiology departments show an increased demand for diagnostic radiologists in 2005, whereas data from the help wanted index show a decrease. In addition, the regional distribution of advertisements and the proportion of advertisements for certain specialties have shown some shifting in 2005. We believe the job market remains strong, with regional and specialty shifting.

Cost accounting in radiology: new directions and importance for policy.

OBJECTIVE: The purpose of this article is to promote insight into radiology costs through improvements in assessing patient-level cost data. Accurate patient costing is a prerequisite for establishing a proper payment system-one where the price paid for a service approximates the cost of delivering that service. In the absence of an accurate payment scheme, margins can vary significantly from one patient to the next. CONCLUSION: The resulting financial incentives skew the radiology marketplace away from the provision of efficient and appropriate care toward the selection of patients whose costs are low relative to reimbursements.

Update on the diagnostic radiologist employment market: findings through 2004.

OBJECTIVE: The objective of this article is to summarize the latest information concerning the diagnostic radiologist employment market. MATERIALS AND METHODS: Three sources of data are presented and compared with previous data: vacancies in academic radiology departments as of July; the ratio of job listings to job seekers at a major placement service; and the number of positions advertised in Radiology and the American Journal of Roentgenology. RESULTS: Vacancies in academic radiology departments averaged 3.9 in 2004, down 29%, and decreased for all subspecialties as compared with 2001, but the number of vacancies remained very similar to that for 2003. Job listings per job seeker were 1.1 in 2004, stable over the past 2 years but at the lowest level since 1997. The overall number of positions advertised declined by 14% in 2003 compared with 2002 and by an additional 17% in 2004, reaching the lowest level since 1998. In 2004, 45.3% of positions advertised were academic. Comparing 2003-2004 with 2001-2002, all geographic regions exhibited absolute declines in advertisements except the Northeast, which showed a 1.5% increase. Absolute increases occurred for musculoskeletal and emergency radiology positions. Statistically significant proportional decreases occurred for general radiology, vascular/interventional radiology, and pediatric radiology. CONCLUSION: Three separate data sources confirm a substantial and broad-based multiyear decline in the strength of the demand for diagnostic radiologists, with some shifting in relative demand for subspecialties. It is not clear if the decrease continued in 2004 or if 2004 demand was similar to that of 2003. Data are relative and do not indicate the employment market is weak in absolute terms.

A comprehensive portrait of teleradiology in radiology practices: results from the American College of Radiology's 1999 Survey.

OBJECTIVE: This article presents a comprehensive portrait of the characteristics of teleradiology systems of radiology practices as of 1999. Our purposes are to help profile a rapidly evolving area of radiology that has been underexamined to date and to provide a baseline with which future findings can be compared. MATERIALS AND METHODS: In 1999, the American College of Radiology surveyed 970 practices by mail. A response rate of 66% was achieved. Responses were weighted to represent all radiology practices in the United States. Data from nine questions specifically designed to profile the use of teleradiology were analyzed using descriptive statistical methods and multivariate regression analyses. RESULTS: Seventy-one percent of multiradiologist practices had teleradiology systems in place, using them to interpret 5% of their studies. For solo practices, corresponding statistics were 30% and 14%. Ninety-two percent of multiradiologist practices with teleradiology systems used them for preliminary on-call interpretation. Other major uses included consultation with other radiologists (20%) and primary interpretation of studies (18%). Ninety-five percent of multiradiologist practices with teleradiology systems used them to interpret CT, 84% used them for sonography, 69% for nuclear medicine, 47% for MRI, and 43% for conventional radiographs. CONCLUSION: Teleradiology had already become a fixture in most practices by 1999, though it was used for only a small fraction of image interpretations. Its widespread presence positioned teleradiology to become a key element of radiology practice nationwide.

Self-referred whole-body imaging: where are we now?

PURPOSE: To identify current patterns and trends of computed tomographic (CT) screening, including geographic data, services provided, facility type, and demographic characteristics. MATERIALS AND METHODS: In March 2003, self-referred body imaging (SRBI) centers were identified by using the Internet. Data involving geographic location, type of facility, services provided, and demographic characteristics were collected. The 2000 U.S. census data were used to compare center locality demographics with national patterns. Descriptive statistics, t tests, and regression analyses were used to evaluate data. Nonstatistical comparisons were made with results obtained from a previously published analysis. RESULTS: The number of SRBI centers totaled 161 (vs 88 in a comparative study in 2001), and centers were distributed across 31 states and Washington, DC (vs 21 in 2001). Racial demographics of center localities more closely resembled national averages in the current study, with equal percentages of whites (76.0% vs 77.1% nationally) and Hispanics (11.5% vs 12.5% nationally). Center localities continued to exhibit greater wealth and levels of education, as reflected by higher income per capita and median household income (P < .05), as well as by higher percentages of people with college and advanced degrees (P < .05). Heart scanning was the most commonly offered service (n = 152, 94%), followed by whole-body scanning (n = 135, 84%), lung scanning (n = 126, 78%), and virtual colonoscopy (n = 88, 55%). Centers in the West were more likely to offer whole-body and organ-specific scanning, compared with centers in other regions (P < .001 for virtual colonoscopy, P < .05 for head scanning). Hospital-based centers were less likely to offer services other than heart scanning (P < .001). CONCLUSION: Compared with results of a prior analysis, SRBI centers have increased and are distributed more widely in areas with a population that more closely resembles national norms. The increased trend to broaden services may suggest possible saturation of the preexisting market.

Diagnostic CT scans: assessment of patient, physician, and radiologist awareness of radiation dose and possible risks.

PURPOSE: To determine the awareness level concerning radiation dose and possible risks associated with computed tomographic (CT) scans among patients, emergency department (ED) physicians, and radiologists. MATERIALS AND METHODS: Adult patients seen in the ED of a U.S. academic medical center during a 2-week period with mild to moderate abdominopelvic or flank pain and who underwent CT were surveyed after acquisition of the CT scan. Patients were asked whether or not they were informed about the risks, benefits, and radiation dose of the CT scan and if they believed that the scan increased their lifetime cancer risk. Patients were also asked to estimate the radiation dose for the CT scan compared with that for one chest radiograph. ED physicians who requested CT scans and radiologists who reviewed the CT scans were surveyed with similar questions and an additional question regarding the number of years in practice. The chi(2) test of independence was used to compare the three respondent groups regarding perceived increased cancer risk from one abdominopelvic CT scan. RESULTS: Seven percent (five of 76) of patients reported that they were told about risks and benefits of their CT scan, while 22% (10 of 45) of ED physicians reported that they had provided such information. Forty-seven percent (18 of 38) of radiologists believed that there was increased cancer risk, whereas only 9% (four of 45) of ED physicians and 3% (two of 76) of patients believed that there was increased risk (chi(2)(2) = 41.45, P <.001). All patients and most ED physicians and radiologists were unable to accurately estimate the dose for one CT scan compared with that for one chest radiograph. CONCLUSION: Patients are not given information about the risks, benefits, and radiation dose for a CT scan. Patients, ED physicians, and radiologists alike are unable to provide accurate estimates of CT doses regardless of their experience level.
