Project description:BackgroundParents play a critical role in their children's introduction to alcohol. A range of parenting factors have been associated with the progression to risky drinking among adolescents, and have recently formed the basis of the Australian 'Parenting Guidelines for Adolescent Alcohol Use' designed to help parents delay or reduce their adolescents' alcohol use.MethodsThis study aimed to explore the experiences and attitudes of parents of adolescents to gain insight into: (1) the extent to which the behaviours of parents follow the recommendations made in the guidelines; and (2) approaches to reduce hazardous drinking among adolescents. Thirty-two telephone and face-to-face interviews were conducted with parents, and the content of discussions was examined using thematic analysis.ResultsParents used approaches they thought would minimise harm and promote healthy development in their children. The guidelines address key areas of concern for parents but their adherence to these approaches is low in certain areas. Many parents provided some alcohol to their adolescents and often cited the social norm of drinking among their adolescents' peers as a source of pressure to supply.ConclusionsFurther dissemination of the guidelines may be the first step in a public health strategy, but it is likely that parents will require support to effectively adopt the recommendations. Understanding the influences on parents' beliefs about their children's drinking and the functions of social networks in the creation of behavioural norms relating to alcohol consumption and supply may be necessary to address adolescent risky drinking.

Project description:Background: Many organisations in Australia undertake systematic reviews to inform development of evidence-based guidelines or would like to do so. However, the substantial resources required to produce systematic reviews limit the feasibility of evidence-based approaches to guideline development. We are working with Australian guideline developers to design, build and test systems that make creating evidence-based guidelines easier and more efficient. Methods: To understand the evidence needs of guideline developers and to inform the development of potential tools and services, we conducted 16 semi-structured interviews with Australian guideline developers. Developers were involved in different types of guidelines, represented both new and established guideline groups, and had access to widely different levels of resources. Results: All guideline developers recognised the importance of having access to timely evidence to support their processes, but were frequently overwhelmed by the scale of this task. Groups developing new guidelines often underestimated the time, expertise and work involved in completing searching and screening. Many were grappling with the challenge of updating and were keen to explore alternatives to the blanket updating of the full guideline. Horizon-scanning and evidence signalling were seen as providing more pragmatic approaches to updating, although some were wary of challenges posed by receiving evidence on a too-frequent basis. Respondents were aware that new technologies, such as machine learning, offered potentially large time and resource savings. Conclusions: As well as the constant challenge of managing financial constraints, Australian guideline developers seeking to develop clinical guidelines face several critical challenges. These include acquiring appropriate methodological expertise, investing in information technology, coping with the proliferation of research output, feasible publication and dissemination options, and keeping guidance up to date.

Project description:BackgroundDepression is the single largest contributor to global disability. There is growing evidence that a healthy diet is associated with reduced depression risk. However, beyond the Mediterranean diet, few longitudinal studies have explored the relationship between adherence to national dietary guidelines and depression. Hence, this study investigates the relationship between adherence to Australian Dietary Guidelines and depressive symptoms.MethodsData was drawn from the READI longitudinal study, a prospective cohort study of socioeconomically disadvantaged Australian women. This analysis includes a sub-sample of 837 women. A generalized linear model was used to explore whether baseline diet (assessed using the Dietary Guideline Index (DGI-2013; score range 0 to 85)) was associated with risk of developing depressive symptoms (measured by the Centre for Epidemiologic Studies Depression (CES-D)) at 5 years follow-up, whilst adjusting for potential confounders. A fixed-effects model was used to assess associations between concurrent changes in diet quality and depressive symptoms from baseline to 5 years follow-up.ResultsAn association between baseline diet quality and risk of developing depressive symptoms at follow-up was observed, where a 10 unit increase in DGI-2013 score was associated with an estimated 12% lower risk of developing heightened depressive symptoms (RR = 0.875, 95%CI 0.784 to 0.978, p = 0.018). The fixed-effects model indicated that an increase in DGI score over 5 years follow-up was associated with a lower (improved) CES-D score (B = -0.044, 95% CI - 0.08 to - 0.01, p = 0.024).ConclusionsOur results provide evidence that better adherence to the Australian Dietary Guidelines may result in improved depressive symptoms. The growing high-quality evidence regarding the diet-depression relationship provides us with a rationale for developing strategies for supporting dietary behaviour change programs to lower depression rates.

Project description:BackgroundClinical practice guidelines have become increasingly widely used to guide quality improvement of clinical practice. Qualitative research may be a useful way to improve the quality and implementation of guidelines. The methodology for qualitative evidence used in guidelines development is worthy of further research.MethodsA comprehensive search was made of WHO, NICE, SIGN, NGC, RNAO, PubMed, Embase, Web of Science, CNKI, Wanfang, CBM, and VIP from January 1, 2011 to February 25, 2020. Guidelines which met IOM criteria and were focused on clinical questions using qualitative research or qualitative evidence, were included. Four authors extracted significant information and entered this onto data extraction forms. The Appraisal of Guidelines for Research and Evaluation (AGREE II) tool was used to evaluate the guidelines' quality. The data were analyzed using SPSS version 17.0 and R version 3.3.2.ResultsSixty four guidelines were identified. The overall quality of the guidelines was high (almost over 60%). Domain 1 (Scope and Purpose) was ranked the highest with a median score of 83% (IQ 78-83). Domain 2 (Stakeholder involvement) and Domain 5 (Applicability) were ranked the lowest with median scores of 67% (IQ 67-78) and 67% (IQ 63-73) respectively. 20% guidelines used qualitative research to identify clinical questions. 86% guidelines used qualitative evidence to support recommendations (mainly based on primary studies, a few on qualitative evidence synthesis). 19% guidelines applied qualitative evidence when considering facilitators and barriers to recommendations' implementation. 52% guideline developers evaluated the quality of the primary qualitative research study using the CASP tool or NICE checklist for qualitative studies. No guidelines evaluated the quality of qualitative evidence synthesis to formulate recommendations. 17% guidelines presented the level of qualitative research using the grade criteria of evidence and recommendation in different forms such as I, III, IV, very low. 28% guidelines described the grades of the recommendations supported by qualitative and quantitative evidence. No guidelines described the grade of recommendations only supported by qualitative evidence.ConclusionsThe majority of the included guidelines were high-quality. Qualitative evidence was mainly used to identify clinical questions, support recommendations, and consider facilitators and barriers to implementation of recommendations'. However, more attention needs to be paid to the methodology. For example, no experts proficient in qualitative research were involved in guideline development groups, no assessment of the quality of qualitative evidence synthesis was included and there was lack of details reported on the level of qualitative evidence or grade of recommendations.

Project description:ObjectiveThis study aimed to explore how general practitioners (GPs) access and use both guidelines and electronic medical records (EMRs) to assist in clinical decision-making when prescribing antibiotics in Australia.DesignThis is an exploratory qualitative study with thematic analysis interpreted using the Theory of Planned Behaviour (TPB) framework.SettingThis study was conducted in general practice in Victoria, Australia.ParticipantsTwenty-six GPs from five general practices were recruited to participate in five focus groups between February and April 2018.ResultsGPs expressed that current EMR systems do not provide clinical decision support to assist with antibiotic prescribing. Access and use of guidelines were variable. GPs who had more clinical experience were less likely to access guidelines than younger and less experienced GPs. Guideline use and guideline-concordant prescribing was facilitated if there was a practice culture encouraging evidence-based practice. However, a lack of access to guidelines and perceived patients' expectation and demand for antibiotics were barriers to guideline-concordant prescribing. Furthermore, guidelines that were easy to access and navigate, free, embedded within EMRs and fit into the clinical workflow were seen as likely to enhance guideline use.ConclusionsCurrent barriers to the use of antibiotic guidelines include GPs' experience, patient factors, practice culture, and ease of access and cost of guidelines. To reduce inappropriate antibiotic prescribing and to promote more rational use of antibiotic in the community, guidelines should be made available, accessible and easy to use, with minimal cost to practicing GPs. Integration of evidence-based antibiotic guidelines within the EMR in the form of a clinical decision support tool could optimise guideline use and increase guideline-concordant prescribing.

Project description:IntroductionEvidence-informed oral health policies are crucial to improving patient and population outcomes, but policymakers and organisational leaders infrequently systematically incorporate research evidence. Although there is indirect evidence regarding challenges in other healthcare sectors, the use of evidence-informed oral health policies remains unstudied in oral health. This study aims to assess policymakers' perceived needs, barriers and facilitators in using research evidence to inform policies in oral health.Methods and analysisThis is a qualitative study situated within a phenomenological paradigm. We will conduct semistructured interviews with policymakers (5-10) affiliated with key organisations conducting guidance, policy statements, guidelines or any knowledge transfer deliverables in oral health. Organisations will be sampled purposively and with no geographical restrictions. All interviews will be recorded, and an audio transcript will be generated. Subsequently, a researcher will review and validate the transcripts. Data will be analysed using thematic analysis supported by ATLAS.ti software.Ethics and disseminationEthical approval was not sought because the study protocol met the criteria for exemption from such review according to the Clinical Research Ethics Committee of the Hospital de la Santa Creu i Sant Pau and the Spanish legislation (Law 14/2007 of 3 July, on biomedical research). Informed consent will be obtained from all subjects involved in this study. The findings of this study will be shared with participating organisations for feedback, disseminated in conferences and published in a peer-reviewed journal adopting open science practices.Study registrationOpen Science Framework (DOI:10.17605/OSF.IO/W4KG7).

Project description:BackgroundSituations such as public health emergencies and outbreaks necessitate the development and publication of high-quality recommendations within a condensed timeframe. For example, WHO has produced examples of and guidance for the development of rapid guidelines (RGs). However, more information is needed to understand the experiences and perceptions of guideline developers. This is the second of a series of three articles addressing methodological issues around RGs. This study describes the perceptions and experiences of guideline developers at WHO about RGs.MethodsWe conducted interviews consisting of open- and closed-ended questions with guideline developers at WHO. Our analysis described the definition and rationale of RGs, the differences from regular guidelines with regard to timelines from topic definition until publication, barriers to identifying the evidence and the lack of a standard methodology to develop RGs.ResultsWe interviewed 10 participants, the majority of whom were comfortable with the current WHO definition of RGs. Most stated that the rationale for developing RGs should be in response to new evidence about efficacy, cost-effectiveness or safety. Respondents differed with regards to the amount of time RGs should take. While the majority of participants agreed that guidelines should be based on a systematic review, this step in the process was considered the most time and resource intensive. Challenges for developing RGs included limited personnel and financial resources as well as the lack of evidence. Facilitators, in turn, that may improve RG development include additional financial and personnel resources as well as the use of virtual meetings.ConclusionsWhile our study suggests a strong need and rationale for the development of RGs, standardisation of timelines and guidance on panel composition, peer-review process, conduct of meetings and sources of permissible evidence require further research.

Project description:Dietary guidelines provide evidence-based guidance for healthy individuals to improve dietary patterns, although they are most often based on individual foods or food groups. Legumes are a class of food included in current Australian Dietary Guidelines (ADG), mentioned in two of the five food groups, as a vegetable and as an alternative to meat. Whole grain consumption is encouraged in ADG via the statement focused on cereal grains due to their health-promoting properties. Despite their prominence in guidelines, average legume and whole grain consumption in Australia remains lower than recommendations outlined in the ADG. This exploratory study aimed to understand consumer perspectives of wording utilised in dietary guidelines specifically focused on legumes and whole grains. Based on the analysis, there was a significant preference for the statement "each day, consume at least one serve of legumes either as a serve of vegetables or as an alternative to meat" (p < 0.05), which provides a specific frequency and quantification for legume consumption. For whole grain, the significantly preferred statement was "choose whole grain products over refined grains/white flour products whenever you can" indicating a less prescriptive option. Effective messaging in guidelines could consider greater specificity regarding frequency, quantity and quality of foods recommended. This exploratory study suggests an improvement in the adoption and consumption of legumes and whole grains in the Australian diet may be better facilitated through consumer-tested messaging.

Project description:BACKGROUND:General practitioners can play an important role in addressing smoking among pregnant women but studies suggest they rarely do so. The aim of this study was to explore general practitioners perceptions about the management of smoking in pregnancy, and what would enable them to provide better care. METHODS:Qualitative semi-structured interviews were conducted (Feb-July 2017), with 19 Australian general practitioners recruited from a sample that participated in a national survey on managing smoking during pregnancy; and through a national conference. The interview guide was structured using the theoretical domains framework, exploring previously reported barriers and two specific components of smoking cessation care - nicotine replacement therapy prescription and Quitline referral. RESULTS:Participants reported high confidence and knowledge to provide pregnant patients adequate support for quitting. Nonetheless, participants reported lacking communication skills, focusing on providing information on smoking harm, accepting cutting down cigarettes as adequate, while following the 'Stages of Change' model and only providing treatment options to motivated patients. Lack of time, nicotine replacement therapy cost and safety concerns, and being unfamiliar with the Quitline (particularly for Aboriginal and Torres Strait Islander pregnant smokers) were perceived as challenges. Participants reported needing better communication skills, clear detailed nicotine replacement therapy guidelines for special populations, and visual resources they could use to discuss treatment options with patients. CONCLUSIONS:Difficulty communicating with pregnant patients about smoking, using the 'Stages of Change' model to guide support provision and concerns regarding nicotine replacement therapy safety are barriers to providing cessation support to pregnant patients for general practitioners. Training on specific effective behaviour change techniques, clear guidance for nicotine replacement therapy use, and practical visual patient education tools may facilitate smoking cessation care provision to pregnant women.

Project description:BackgroundWHO has recognised the need to ensure that guideline processes are transparent and evidence based, and that the resulting recommendations are relevant and applicable. Along with decision-making criteria that require findings from effectiveness reviews, WHO is increasingly using evidence derived from qualitative evidence syntheses (QES) to inform the values, acceptability, equity and feasibility implications of its recommendations. This is the first in a series of three papers examining the use of QES in developing clinical and health systems guidelines.MethodsWHO convened a group of methodologists involved in developing recent (2010-2018) guidelines that were informed by QES. Using a pragmatic and iterative approach that included feedback from WHO staff and other stakeholders, the group reflected on, discussed and identified key methods and research implications from designing QES and using the resulting findings in guideline development. Our aim in this paper is to (1) describe and discuss how the findings of QES can inform the scope of a guideline and (2) develop findings for key guideline decision-making criteria.ResultsQES resulted in the addition of new outcomes that are directly relevant to service users, a stronger evidence base for decisions about how much effective interventions and related outcomes are valued by stakeholders in a range of contexts, and a more complete database of summary evidence for guideline panels to consider, linked to decisions about values, acceptability, feasibility and equity.ConclusionsRigorously conducted QES can be a powerful means of improving the relevance of guidelines, and of ensuring that the concerns of stakeholders, at all levels of the healthcare system and from a wide range of settings, are taken into account at all stages of the process.
