Background Over the past decade, mammography has transitioned from film to digital media with promises of increased productivity and time savings. Between 2007 and 2010 in Nova Scotia, 10 mammography sites transitioned from analog to digital, providing a natural experiment to evaluate the transition (full-field digital mammography) on mammography with respect to changes in throughput volumes in a “real-world” setting. Methods Study data consisted of aggregate, monthly, site-specific counts of screening and diagnostic mammograms for the period 2006 to 2014, which were obtained from an information system that supports central booking, clinical reporting, and patient management for all breast imaging in Nova Scotia. A multigroup interrupted time series design using segmented regression with site-month data assessed pre-to post-transition changes in screening throughput volumes and the proportion of diagnostic mammograms performed. Results The overall mean monthly number of mammograms per machine per full-time equivalent increased by 17% from 192.9 (95% confidence interval: 182.7–203.1) to 225.7 (95% CI 218.3–233.0); however, there was marked heterogeneity across these sites. A pooled analysis for all sites revealed that there was no statistically significantly change in the proportion of diagnostic mammograms performed after transition. Conclusions Increases in throughput volumes were observed only in some sites, suggesting unmeasured site-specific factors may have limited the potential for improvement. Interrupted time series methods are an appropriate and meaningful approach for evaluating technology and procedure changes in diagnostic imaging.

Background Empathy is an essential behavioural competency required of healthcare providers. It is included in the Canadian National Competency Profile for Medical Radiation Technologists; supporting patient-centered care and the development of therapeutic relationships between carers and care recipients. This review synthesizes evidence on Virtual Reality (VR) as a tool for eliciting empathetic behaviour in carers. Methods Six Electronic databases (PubMed, EMBASE, PsycInfo, ERIC, Academic Search Premier and CINAHL) were searched for studies published from 1997–2020. Studies with MeSH terms “Empathy” and “Virtual Reality”, and conducted on adult carers, were eligible for inclusion. The Cochrane risk of bias tool guided the assessment of study quality. Prospero review registration number: CRD42020210049 Results Seven studies, with 485 carers, were included in this review. Studies were heterogeneous in terms of interventions and tools for collecting outcome measures. All seven studies demonstrated VR could elicit empathetic behaviour in carers. Studies included one randomized controlled trial, three non-randomized controlled trials, two with quasi-experimental designs, and one non-experimental design. All studies had a moderate to high risk of bias. Conclusion This review suggests that VR may be an appropriate method for eliciting empathetic behaviours in carers. Future studies employing appropriately powered multicentere randomized controlled designs should seek to determine which VR experiences are the most effective in evoking empathetic behaviours.
