patterns of smoking and vaping of university students in Australia and NZ, and a strong influence of gender on smoking and vaping. We studied time trends in seasonal influenza vaccination and associations with socioeconomic and health-related determinants in Switzerland, overall and in people aged ≥65 years. Three cross-sectional surveys. Individuals who participated in the Swiss Health Surveys 2007, 2012 and 2017. We calculated the proportion reporting influenza vaccination in the last 12 months, and performed multivariable logistic regression analyses. We included 51 582 individuals in this analysis. The median age was 49 years (IQR 25-64), and 27 518 were women (53.3%). The proportion of reporting a history of influenza vaccination overall was 31.9% (95% CI 31.4 to 32.4); and dropped from 34.5% in 2007 to 28.8% in 2017. The uptake of vaccination within the past 12 months was 16% in 2007 and similar in 2012 and 2017 (around 14%). In people with chronic disease, uptake dropped from 43.8% in 2007 to 37.1% in 2012 and to 31.6% in 2017 (p<0.001). In people aged ≥65 years, uptake dropped from 47.8% in 2007 to 38.5% in 2012 to 36.luenza. These efforts should include campaigns but also novel approaches using social media. Antimicrobial treatment of asymptomatic bacteriuria (ASB) is one of the most common unnecessary uses of antimicrobials. Earlier studies have shown that the prevalence of this inappropriate treatment ranges from 45% to 83%. Multifaceted interventions based on international guidelines and antimicrobial stewardship can decrease overtreatment of ASB. We have designed a study protocol with the main objective of reducing overtreatment of ASB by 50% through use of a deimplementation strategy. We will use a stepped-wedge cluster randomised design, comparing outcomes before and after introduction of our intervention in the emergency department (ED) of five hospitals (clusters) in the Netherlands. All patients (≥18 years old) who have a urine test performed in the ED will be screened for eligibility. The deimplementation strategy consists of a combination of interventions, including education, audit and feedback. The primary endpoint is overtreatment of ASB in patients without risk factors (eg, pregnancy, planned invasive urological procedures and neutropenia). Secondary endpoints are the duration of antimicrobial treatment for ASB, the number of urine cultures and urinalysis per 1000 patients, and overtreatment of positive urinalysis in asymptomatic patients. Ethical approval was obtained from the medical ethics research committee of the Academic Medical Centre (Amsterdam, the Netherlands) with a waiver for informed consent. Local feasibility was obtained by the local institutional review boards of all participating hospitals. Our study aims to reduce inappropriate screening and treatment of ASB in EDs, improve healthcare quality, lower the increase in antimicrobial resistance and save costs. If proven (cost)-effective, this study provides a well-suited strategy for a nationwide approach to reduce overtreatment of ASB. Relevant results of our study will be disseminated through publications in peer-reviewed journals and presentations at relevant (scientific) conferences. NL8242; Pre-results.NL8242; Pre-results. Unfortunately, like many other health risks, smoking rate has been on the rise in developing countries. Half of current smokers in the world reside in only three countries of Asia that include India. Many smoking cessation interventions that were developed and successfully implemented in the context of developed countries have not been equally successful in South Asia. Hence, there is a dire need of culturally relevant smoking cessation interventions. We propose a scoping review with objectives to explore the extent and nature of interventions for smoking cessation and its associated factors in South Asian Region by systematically reviewing the available published and unpublished literature. The review has been registered in Joanna Briggs Institute (JBI) systematic reviews register and details are given in the Methodology section. NX-1607 The updated framework of JBI for scoping review methodology will be used as guide for conduct of this scoping review. Electronic databases (PubMed, CINAHL plus, Proquest Theses c databases (PubMed, CINAHL plus, Proquest Theses and Dissertations, EBSCO Dentistry and Oral Sciences, and Wiley Cochrane Library), reference lists of selected studies and grey literature will be considered for inclusion in this review. The literature search is anticipated to be carried out in December-January 2020. Initially, two reviewers in consultation with a librarian will develop search syntax followed by search from the selected sources. Consequently, the reviewers will screen all the titles, abstracts and full articles to establish relevance of each study for inclusion. Factors associated with smoking cessation will be coded and categorised applying qualitative content analysis, while interventions extracted from the literature will be described with the stated level of effectiveness. Conducting a national survey of clinicians and administrators from specialised dementia assessment services (memory clinics) in Australia to examine their current organisational aspects and assessment procedures and inform clinical tool harmonisation as part of the Australian Dementia Network-memory clinics project. A cross-sectional survey. Public and private memory clinics across Australia. 150 individual clinicians completed the survey between May and August 2019. Responses could be given anonymously. Most clinics were publicly funded services (83.2%) and in metropolitan regions (70.9%). Descriptive data on organisational aspects of memory clinics (eg, waiting times, staffing); the three most commonly used assessment tools per assessment type (eg, self-report) and cognitive domain (eg, attention). Since the last national survey in 2009, the number of memory clinics across Australia has increased substantially but considerable variability has remained with respect to funding structure, staffing and assessment procedures.
