This study compared the efficacy of two cardiac anatomy teaching modalities, ultrasound imaging and cadaveric prosections, for learning cardiac gross anatomy. One hundred and eight first-year medical students participated. Two weeks prior to the teaching intervention, students completed a pretest to assess their prior knowledge and to ensure that groups were equally randomized. Students, divided into pre-existing teaching groups, were assigned to one of two conditions; "cadaver" or "ultrasound." Those in the cadaver group received teaching on the heart using prosections, whereas the ultrasound group received teaching using live ultrasound images of the heart. Immediately after teaching, students sat a post-test. Both teaching modalities increased students' test scores by similar amounts but no significant difference was found between the two conditions, suggesting that both prosections and ultrasound are equally effective methods for teaching gross anatomy of the heart. Our data support the inclusion of either cadaveric teaching or living anatomy using ultrasound within the undergraduate anatomy curriculum, and further work is needed to compare the additive effect of the two modalities.
ObjectiveTo determine the prevalence of work-related psychological distress in staff working in UK paediatric intensive care units (PICU).DesignOnline (Qualtrics) staff questionnaire, conducted April to May 2018.SettingStaff working in 29 PICUs and 10 PICU transport services were invited to participate.Participants1656 staff completed the survey: 1194 nurses, 270 physicians and 192 others. 234 (14%) respondents were male. Median age was 35 (IQR 28–44).Main outcome measuresThe Moral Distress Scale-Revised (MDS-R) was used to look at moral distress, the abbreviated Maslach Burnout Inventory to examine the depersonalisation and emotional exhaustion domains of burnout, and the Trauma Screening Questionnaire (TSQ) to assess risk of post-traumatic stress disorder (PTSD).Results435/1194 (36%) nurses, 48/270 (18%) physicians and 19/192 (10%) other staff scored above the study threshold for moral distress (≥90 on MDS-R) (χ2 test, p<0.00001). 594/1194 (50%) nurses, 99/270 (37%) physicians and 86/192 (45%) other staff had high burnout scores (χ2 test, p=0.0004). 366/1194 (31%) nurses, 42/270 (16%) physicians and 21/192 (11%) other staff scored at risk for PTSD (χ2 test, p<0.00001). Junior nurses were at highest risk of moral distress and PTSD, and junior doctors of burnout. Larger unit size was associated with higher MDS-R, burnout and TSQ scores.ConclusionsThese results suggest that UK PICU staff are experiencing work-related distress. Further studies are needed to understand causation and to develop strategies for prevention and treatment.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
