Impact of Biases in Selection and Evaluation on the Composition of the Radiology Physician Workforce.

Lack of diversity in Radiology is a public health problem and may be self perpetuating as diverse candidates view the field as hostile to their entry and advancement, and consequently do not apply into the field. Solutions require understanding the obstacles, which range from enrollment in medical school to achieving leadership positions in Radiology. An understanding of the effect of demographic data on diversity in Radiology, disparate effects of Step examinations, medical school grades and induction into academic honor societies, and existing faculty disparities will allow us to better recruit, train, and retain a diverse group of physicians in our field. The downstream effect of a diverse workforce is improvement in health outcomes and disparities in medical care for our communities.

Role of C-reactive protein in effective utilization of emergent MRI for spinal infections.

PURPOSE: Emergent spinal MRI is recommended for patients with back pain and red flags for infection. However, many of these studies are negative due to low prevalence of spinal infections. Our purpose was to assess if C-reactive protein (CRP) can be used to guide effective utilization of emergent MRI for spinal infections. METHODS: 316/960 (33%) MRIs performed for infection by the emergency department over 75-month period had CRP levels obtained at presentation, after excluding patients receiving antibiotic or had spinal surgery in < 1 month. An MRI was considered positive when there was imaging evidence of spinal infection confirmed on follow-up by surgery/biopsy/drainage or definitive therapy. A CRP of ≤ 10 mg/L was considered normal and > 100 mg/L as highly elevated. RESULTS: CRP was normal in 95/316 (30%) and abnormal in 221/316 (70%) patients. MRI was positive in 43/316 (13.6%) patients, all of whom had abnormal CRP. CRP (p < 0.001) and intravenous drug use (IVDU; p = 0.002) were independently associated with a positive MRI. Receiver operator characteristic (ROC) analysis showed AUC of 0.76 for CRP, slightly improving with IVDU. Sensitivity, specificity, and negative predictive values for CRP level cut-off: 10 mg/L, 100%, 35%, and 100%, and 100 mg/L, 58%, 70% and 91%, respectively. CONCLUSION: Abnormal CRP, although extremely sensitive, lacks specificity in predicting a positive MRI for spinal infection unless highly elevated. However, a normal CRP (absent recent antibiotic or surgery) makes spinal infection unlikely, and its routine use as a screening test can help reducing utilization of emergent MRI for this purpose.

A population-based study of outcomes from thyroidectomy in aging Americans: at what cost?

BACKGROUND: We wanted to evaluate clinical and economic outcomes after thyroidectomy in patients 65 years of age and older, with special analyses of those aged 80 years and older, in the US. STUDY DESIGN: This was a population-based study using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample, 2003-2004, a national administrative database of all patients undergoing thyroidectomy and their surgeon providers. Independent variables included patient demographic and clinical characteristics and surgeon descriptors, including case volume. Clinical and economic outcomes included mean total costs and length of stay (LOS), in-hospital mortality, discharge status, and complications. RESULTS: There were 22,848 patients who underwent thyroidectomies, including 4,092 (18%) aged 65 to 79 years and 744 (3%) 80 years of age or older. On a population level, patient age is an independent predictor of clinical and economic outcomes. Average LOS for patients 80 years and older is 60% longer than for similar patients 65 to 79 years of age (2.9 versus 2.2 days; p < 0.001), complication rates are 34% higher (5.6% versus 2.1%; p < 0.001), and total costs are 28% greater ($7,084 versus $5,917; p < 0.001). High-volume surgeons have shorter LOS and fewer complications but perform fewer thyroidectomies for aging Americans; although they do nearly 29% of these procedures in patients younger than 65 years, they do just 15% of thyroidectomies in patients 80 years and older and 23% in patients 65 to 79 years. CONCLUSIONS: On a population level, clinical and economic outcomes for patients 65 years and older undergoing thyroidectomies are considerably worse than for similar, younger patients. The majority of thyroidectomies in aging Americans is performed by low-volume surgeons. More data are needed about longterm outcomes, but increased referrals to high-volume surgeons for aging Americans are necessary.

The maturation of a specialty: Workforce projections for endocrine surgery.

BACKGROUND: There has been an increase in the incidence of endocrine diseases and the number of endocrine procedures in the United States. Higher surgeon volume is associated with improved patient outcomes. Fellowship programs will lead to more specialty-trained endocrine surgeons. We make projections for the supply of endocrine surgeons and demand for endocrine procedures over the next 15 years. METHODS: Supply projections are based on data from the Accreditation Council for Graduate Medical Education, a survey of American Association of Endocrine Surgery fellowship program graduates, and Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS). Demand is estimated using HCUP-NIS, U.S. Census Bureau projections, and a literature review. RESULTS: There were 64,275 endocrine procedures performed in 2000 and 80,505 in 2004. Using age-adjusted population projections and increasing incidence of endocrine diseases, 103,704 endocrine procedures are anticipated in 2020. High-volume endocrine surgeons are few in number, but perform 24% of endocrine procedures. Surgeon supply is projected to increase to 938 by 2020; this is based on fellowship graduation rates, retirement trends, and increasing annual endocrine case volume among high-volume surgeons. Alternative projections of supply and demand are generated to test the sensitivity of our analyses to different assumptions. CONCLUSION: Labor force planning in endocrine surgery is essential if the demand for more high-volume endocrine specialists is to be met.

Racial disparities in clinical and economic outcomes from thyroidectomy.

CONTEXT: Thyroid disease is common, and thyroidectomy is a mainstay of treatment for many benign and malignant thyroid conditions. Overall, thyroidectomy is associated with favorable outcomes, particularly if experienced surgeons perform it. OBJECTIVE: To examine racial differences in clinical and economic outcomes of patients undergoing thyroidectomy in the United States. DESIGN, SETTING, PATIENTS: The nationwide inpatient sample was used to identify thyroidectomy admissions from 1999 to 2004, using ICD-9 procedure codes. Race and other clinical and demographic characteristics of patients were collected along with surgeon volume and hospital characteristics to predict outcomes. MAIN OUTCOME MEASURES: Inpatient mortality, complication rates, length of stay (LOS), discharge status, and mean total costs by racial group. RESULTS: In 2003-2004, 16,878 patients underwent thyroid procedures; 71% were white, 14% black, 9% Hispanic, and 6% other. Mean LOS was longer for blacks (2.5 days) than for whites (1.8 days, P < 0.001); Hispanics had an intermediate LOS (2.2 days). Although rare, in-hospital mortality was higher for blacks (0.4%) compared with that for other races (0.1%, P < 0.001). Blacks trended toward higher overall complication rates (4.9%) compared with whites (3.8%) and Hispanics (3.6%, P = 0.056). Mean total costs were significantly lower for whites ($5447/patient) compared with those for blacks ($6587) and Hispanics ($6294). The majority of Hispanics (55%) and blacks (52%) had surgery by the lowest-volume surgeons (1-9 cases per year), compared with only 44% of whites. Highest-volume surgeons (>100 cases per year) performed 5% of thyroidectomies, but 90% of their patients were white (P < 0.001). Racial disparities in outcomes persist after adjustment for surgeon volume group. CONCLUSIONS: These findings suggest that, although thyroidectomy is considered safe, significant racial disparities exist in clinical and economic outcomes. In part, inequalities result from racial differences in access to experienced surgeons; more data are needed with regard to racial differences in thyroid biology and surveillance to explain the balance of observed disparities.
