Postgraduate musculoskeletal fellowship training in the United States: current trends and future direction

Diagnostic performance of magnetic resonance imaging and pre-surgical evaluation in the assessment of traumatic intra-articular knee disorders in children and adolescents: what conditions still pose diagnostic challenges?

BACKGROUND

Diagnosis of intra-articular lesions in children based on clinical examination and MRI is particularly challenging.

OBJECTIVE

To evaluate the diagnostic performance of MRI and pre-surgical evaluation of the knee in pediatric patients relative to arthroscopic evaluation as the gold standard. We report diagnoses frequently missed or inaccurately diagnosed pre-operatively.

MATERIALS AND METHODS

We conducted a retrospective review of MRI and pre-surgical evaluation in children and adolescents ages 1-17 years who were treated by knee arthroscopy during a 2½-year period. All MRIs were reviewed by a pediatric radiologist blinded to clinical findings. Pediatric orthopedic clinic notes were reviewed for pre-surgical evaluation (based on physical exam, radiograph, MR images and radiologist's MRI report). Arthroscopic findings were used as the gold standard. We calculated the percentages of diagnoses at arthroscopy missed on both MRI and pre-surgical evaluation. Diagnostic accuracy between children and adolescents and in patients with one pathological lesion vs. those with >1 lesion was analyzed. We performed a second review of MR images of the missed or over-called MRI diagnoses with knowledge of arthroscopic findings.

RESULTS

We included 178 children and adolescents. The most common diagnoses missed on MRI or pre-surgical evaluation but found at arthroscopy were: discoid meniscus (8/30, or 26.7% of cases); lateral meniscal tears (15/80, or 18.8% of cases); intra-articular loose bodies (5/36, or 13.9% of cases), and osteochondral injuries (9/73, or 12.3% of cases). Overall diagnostic accuracy of MRI and pre-surgical evaluation was 92.7% and 95.3%, respectively. No significant difference in diagnostic accuracy between children and adolescents was observed. When multiple intra-articular lesions were present, lateral meniscal tears were more likely to be inaccurately diagnosed (missed or over-called) on both MRI (P = 0.009) and pre-surgical evaluation (P < 0.001).

CONCLUSION

Overall diagnostic accuracy of MRI and pre-surgical evaluation was quite high. The traumatic intra-articular knee lesions that still pose a diagnostic challenge for MRI and pre-surgical evaluation are lateral discoid meniscus, lateral meniscal tears, intra-articular loose bodies and osteochondral injuries. Special attention should be given to those diagnoses when evaluating a pediatric knee MRI. In children with multiple intra-articular injuries, there is significantly more inaccuracy in pre-arthroscopic diagnosis of lateral meniscal tears on both MRI and pre-surgical evaluation.

Developments and innovations in resident and fellowship education: review article

BACKGROUND

Medical trainee education has drastically changed over the past 30 years significantly since the inception of the Accreditation Council for Graduate Medical Education (ACGME) in 1981. With an emphasis on patient safety, regulations and oversight from the ACGME have drastically changed the way many programs function with respect to trainee responsibilities, duty hours, and resident supervision.

QUESTIONS/PURPOSES

The purpose of this review is to summarize significant changes and innovations implemented by the ACGME and their proposed effects on trainee education. While there is an emphasis on musculoskeletal radiology fellowship training, the majority of the regulations and guidelines are applicable to all training programs.

METHODS

Articles, commentaries, and policies focusing on ACGME requirements were reviewed, with a focus on musculoskeletal radiology.

RESULTS

Changes in ACGME policies have resulted in significant structural modifications in how training programs are designed, specifically with respect to curriculum standardization, measuring outcomes of trainee performance, and integration of residents and fellows into hospital-based quality improvement and patient safety initiatives.

CONCLUSION

With an eye to continued training program advancement and improvement, the goal of universal oversight and standardization in medical training remains to produce forward-thinking physicians with an emphasis on lifelong learning, patient care, and quality improvement.

Musculoskeletal ultrasound: focused impact on MRI

OBJECTIVE

This article will compare and contrast image interpretation, accuracy, observer variability, economic impact, and education with regard to musculoskeletal ultrasound and MRI because these factors will influence the growth of musculoskeletal ultrasound and the impact on MRI.

CONCLUSION

The use of musculoskeletal ultrasound continues to grow and there are a number of factors that impact MRI. The development of less expensive portable ultrasound machines has opened the market to nonradiologists, and applications for musculoskeletal ultrasound have broadened. Selective substitution of musculoskeletal ultrasound for MRI can result in significant cost saving to the health care system. Although this change could decrease the use of MRI, issues related to accuracy, variability, education, and competence must be addressed.

MRI interpretation proficiency of musculoskeletal fellows in training

RATIONALE AND OBJECTIVES

The aim of this study was to evaluate the magnetic resonance imaging (MRI) interpretation proficiency of musculoskeletal fellows in training.

MATERIALS AND METHODS

Between July 2003 and June 2007, 14 musculoskeletal fellows were independently tested with 20 MRI studies of the knee and shoulder at four separate time points during their fellowship years. Trends in true-positive and false-positive interpretation results were evaluated. Fellows who completed their residencies at the fellowship institution (internal fellows) were compared with those from other residencies (external fellows).

RESULTS

There was a significant improvement in proficiency between the initial and final (9-month) evaluations (P < .0001). At the initial evaluation, there was a mean of 52.8% (41.7 of 79) true-positive results (range, 32-51); at 9 months, there was a mean of 71.0% (56.1 of 79; range, 40-72). The number of false-positive results also declined during this time period from a mean of 8.1 (range, 2-13) at initial evaluation to 4.7 (range, 2-8) at 9 months (P < .001). External fellows had more incorrect diagnoses initially but showed greater improvement than internal fellows at 9 months.

CONCLUSION

Fellows continued to improve their MRI interpretation skills throughout the first 9 months of their fellowships. External fellows were slightly less proficient at the start of their fellowships but slightly more proficient at 9 months compared to internal fellows.

A metric to evaluate the comparative performance of an institution's graduate medical education program

The economics of medicine have drastically changed during the past quarter century. Institutions may be faced with difficult decisions concerning graduate medical education (GME), particularly as it relates to the growth of existing programs and the creation of new programs. The authors describe a tool that they developed that can consistently measure the value of individual training programs while aligning with an institution's strategic priorities. This tool, the assessment metric scorecard, permits the annual prioritization of GME programs by the leadership of Mayo Clinic, Jacksonville, Florida. The scorecard also provides valuable data regarding the strengths and weaknesses of individual programs. The metric seeks to evaluate GME programs on the basis of four broad areas: Research, Teaching, Patient Service, and a General category. The assessment metric scorecard has been used since 2004; this article reports on its use for the academic years 2004-2005 and 2005-2006. The scorecard has proved to be a helpful tool for the yearly evaluation and prioritization of GME programs at the authors' institution. The overall mean score of the GME programs increased, which suggests a positive trend. This scorecard is flexible; modifications of the relative weights of the metrics can be made to align it with the strategic priorities of other institutions. The resources necessary to implement the scorecard are minimal.
