New mammography screening performance metrics based on the entire screening episode.
Established mammography screening performance metrics use the initial screening mammography assessment because they were developed for radiologist performance auditing, yet these metrics are frequently used to inform health policy and screening decision making. The authors developed new performance metrics based on the final assessment that consider the entire screening episode, including diagnostic workup. They concluded that established screening performance metrics underestimated the interval cancer rate of a mammography screening episode, particularly for women with dense breasts or an elevated breast cancer risk.

Assessment of radiologist performance in breast cancer screening using digital breast tomosynthesis vs digital mammography.
Many US radiologists have screening mammography recall rates above the expert-recommended threshold of 12%. The influence of digital breast tomosynthesis (DBT) on the distribution of radiologist recall rates is uncertain. The objective of this study was to evaluate radiologists' recall and cancer detection rates before and after beginning interpretation of DBT examinations.

Early stroke recognition and time-based emergency care performance metrics for intracerebral hemorrhage.
This study compared time for early stroke recognition for intracerebral hemorrhage for hospitals with and without stroke teams. An observational cohort study was conducted at an urban comprehensive stroke center from 2009 to 2017 with 204 cases included. Stroke team activation resulted in faster emergency care compared to no activation. This process resulted in shorter onset-to-arrival times, higher NIH Stroke Scale scores, and higher Glasgow Coma Scale scores.

Formative assessment of performance in diagnostic ultrasound using simulation and quantitative and objective metrics.
The authors of this article describe how they developed simulator-based tools for assessing provider competence in transthoracic echocardiography (TTE) and vascular duplex scanning. Psychomotor skill in TTE image acquisition was calculated using the deviation angle of an acquired image from the anatomically correct view, and this skill metric applied for formative assessment to evaluate curricula and provide feedback to learners. Psychomotor skill in vascular ultrasound was measured in terms of dexterity and image plane location. The skill metric in the TTE simulator enabled immediate feedback, as well as formative assessment of curriculum efficacy and a comparison of curriculum outcomes. The vascular duplex ultrasound simulator also provided feedback. The authors conclude that skill in acquiring diagnostic ultrasound images of organs and vessels can be measured using simulation in an objective, quantitative, and standardized manner. Simulator-based metrics might also be applied to summative assessment.

Radiologists' interpretive skills in screening vs. diagnostic mammography: are they related?
This study aimed to determine whether radiologists who perform well in screening also perform well in interpreting diagnostic mammography. It evaluated the accuracy of 468 radiologists interpreting 2,234,947 screening and 196,164 diagnostic mammograms and found a moderate correlation for radiologists' accuracy when interpreting screening versus their accuracy on diagnostic examinations.
