Abstract: Nudge interventions are those that seek to modify the social and physical environment to enhance capacity for subconscious behaviours that align with the intrinsic values of an in idual, without actively restricting options. This study sought to describe the application and effects of nudge strategies on clinician implementation of health-related guidelines, policies and practices within studies included in relevant Cochrane systematic reviews. As there is varied terminology used to describe nudge, this study examined studies within relevant systematic reviews. A two-stage screening process was undertaken where, firstly, all systematic reviews published in the Cochrane Library between 2016 and 2018 were screened to identify reviews that included quantitative studies to improve implementation of guidelines among healthcare providers. Secondly, in idual studies within relevant systematic reviews were included if they were (i) randomised controlled trials (RCTs), (ii) included a nudge strategy in at least one intervention arm, and (iii) explicitly aimed to improve clinician implementation behaviour. We categorised nudge strategies into priming, salience and affect, default, incentives, commitment and ego, and norms and messenger based on the Mindspace framework. The number and percentage of trials using each nudge strategy was calculated. Due to substantial heterogeneity, we did not undertake a meta-analysis. Instead, we calculated within-study point estimates and 95% confidence intervals, and used a vote-counting approach to explore effects. Seven reviews including 42 trials reporting on 57 outcomes were included. The most common nudge strategy was priming (69%), then norms and messenger (40%). Of the 57 outcomes, 86% had an effect on clinician behaviour in the hypothesised direction, and 53% of those were statistically significant. For continuous outcomes, the median effect size was 0.39 (0.22, 0.45), while for dichotomous outcomes the median Odds Ratio was 1.62 (1.13, 2.76). This review of 42 RCTs included in Cochrane systematic reviews found that the impact of nudge strategies on clinician behaviour was at least comparable to other interventions targeting implementation of evidence-based guidelines. While uncertainty remains, the review provides justification for ongoing investigation of the evaluation and application of nudge interventions to support provider behaviour change. This review was not prospectively registered.

Abstract: Continued technological progress in robotic systems has led to more applications where robots and humans operate in close proximity and even physical contact in some cases. Soft robots, which are made of highly compliant and deformable materials, provide inherent safety features unlike conventional robots that are made of stiff and rigid components. Soft robotics is a rapidly developing field exploiting biomimetic design principles, novel sensor and actuation concepts, and advanced manufacturing techniques. In this study, we propose novel 3D printable soft vacuum actuators that are inspired by the sporangium of fern trees. These actuators that are directly manufactured using commercial and affordable fused deposition modeling 3D printers offer many advantages such as high actuation speed (5.54 Hz), long lifetime (123,000 cycles), large payload to weight ratio (∼26), and significant output forces (∼16 N). The behavior of these actuators is accurately predicted, and their performance is optimized using finite element modeling. Furthermore, erse robotic applications such as locomotion robots (a walking robot moving with an average forward speed of

Abstract: Alcohol use in pregnancy remains common in Australia, despite national guidelines recommending that pregnant women abstain. The aims of this study were to investigate where pregnant women obtain information about alcohol use in pregnancy and the relationship between the information source used and women's demographic characteristics and alcohol use. In this cross‐sectional survey of pregnant women attending public maternity services in the Hunter New England region (New South Wales), women were asked, ‘Where did you get information to help you make decisions about alcohol use during pregnancy?’. The number and types of information sources were analysed using descriptive statistics. Associations between women's information sources, and their demographic characteristics and alcohol use in pregnancy were assessed using chi‐square tests and logistic regression. Of 4511 pregnant women surveyed, 80.1% used at least one type of information source (range 0–5). Written/electronic information (45.4%), health providers (37.6%) and family/friends (19.5%) were the sources most reported. Higher use of written/electronic information, antenatal health providers and family/friends was associated with first pregnancy, younger age and higher education. The type of information source used was associated with alcohol use in pregnancy. Women who reported alcohol use were more likely to receive information from written/electronic sources. Almost 20% of women (older, multiparous [ pregnancy] and more highly educated) obtained no information regarding alcohol use in pregnancy. Antenatal providers should routinely provide information on alcohol use in pregnancy, including for women least likely to access available information.
