Development of Report Turnaround Times in a University Department of Radiology during Implementation of a Reformed Curriculum for Undergraduate Medical Education.

PURPOSE: The implementation of a reformed curriculum for undergraduate medical education with a problem-oriented focus and more bedside teaching in small groups increases the academic teaching workload. The aim of this study was to investigate whether this increase in teaching duties is associated with an increase in report turnaround times of radiologists or increased unplanned absence during term times compared with term breaks (lecture-free periods) and over the whole period under investigation. MATERIALS AND METHODS: The database of all radiological examinations performed at a large German university hospital was retrospectively analyzed for a two-year period from the winter term 2011/12 to the summer term 2013. A total of 192 984 radiological examinations performed during this period were included in an analysis of reporting times (i. e., time from end of examination to completion of report) during term times versus term breaks. Reporting times were analyzed for all radiological examinations and for intensive care unit (ICU) patients. In addition, radiologists' schedules were analyzed in terms of teaching duties, unplanned absence, vacation days, and days away from work for education and training. RESULTS: During the period under investigation, the teaching load increased from overall 1.75 hours/day in the winter term 2011/12 to 6.49 hours/day in the summer term 2013 and in the term break from overall 0.10 hours/day in the winter term 2011/12 to 0.71 hours/day in the summer term 2013. Reporting time increased during this period (p < 0.05) but remained shorter during term times than during term breaks. The difference between term and term break for ICU patients was not significant. There was no increase in unplanned absences during term times. CONCLUSION: Overall, radiologists' reporting times increased during the period when the reformed curriculum for undergraduate medical education was implemented. As this was observed both during term and during term breaks, increased teaching duties alone cannot serve as a sole causal explanation. KEY POINTS: · Digital high-quantitative parameters can be used to evaluate workflow in radiology.. · Reporting time can be a criterion for efficient staffing.. · The acquisition and evaluation of parameters such as reporting times could lead to a more efficient resource allocation by providing hints of changed framework conditions and changing working intensities and/or capicity reserves - which may not be immediately apparent.. · During the period under investigation with the implementation of a teaching-intensive reformed curriculum for undergraduate medical education there was an increase in reporting time, which was not significant in intense care units.. · Since during the period under investigation the increase in reporting times can be stated both during term time and in the lecture free period, the implementation of the reformed curriculum for undergraduate medical education alone cannot serve as a sole causal explanation..

Tailored interactive sequences for continuous MR-image-guided freehand biopsies of different organs in an open system at 1.0 tesla (T) - Initial experience.

OBJECTIVES: To assess the feasibility, image quality, and accuracy of freehand biopsies of liver, bone, muscle, vertebral disc, soft tissue, and other lesions using balanced steady-state free precession (SSFP, balanced fast field echo: bFFE), spoiled and nonspoiled gradient echo (FFE), and turbo spin echo (TSE) sequences for interactive continuous navigation in an open magnetic resonance imaging (MRI) system at 1.0 tesla (T). METHODS: Twenty-six MR-guided biopsies (five liver, five bone, four muscle, four vertebral disc, one lung, one kidney, one suprarenal gland, and five soft or other tissue) were performed in 23 patients in a 1.0-T open magnetic resonance (MR) scanner (Panorama HFO, Philips Healthcare, Best, the Netherlands). A total of 42 samples were obtained. Depending on lesion size and location, 14-18-gauge MR-compatible biopsy sets with a length of 100 or 200 mm (Somatex Medical, Teltow, Germany), 14-18-gauge MR-compatible semiautomatic biopsy guns with a length of 100 or 150 mm (Invivo, Schwerin, Germany), or 11-gauge MR-compatible bone marrow biopsy needles with a length of 100 mm (Somatex Medical, Teltow, Germany) were employed. RESULTS: All lesions were visible with continuous interactive imaging. Our initial results indicate that bFFE is particularly suitable for fast-moving organs (pulmonary, paracardial); moving organs are targeted better with T1-weighted (T1W) TSE, T1W FFE (liver) or T2-weighted (T2W) TSE (complicated cysts, adrenal glands), and static organs are successfully approached with proton density (PD) (spine) or T1W TSE (peripheral bones, musculoskeletal system). No adverse events related to the use of MRI were obtained. No complications occurred according to the Society of Interventional Radiology (SIR) clinical practice guidelines. CONCLUSION: Applying tailored interactive dynamic imaging sequences for continuous navigation to liver, bone, muscle, vertebral disc, soft tissue, and other lesions can improve the feasibility, image quality, and interventional accuracy of freehand MR-guided biopsies and may hence reduce the risk of complications.
