Project description:Multivariate analysis refers to statistical techniques that simultaneously look at three or more variables in relation to the subjects under investigation with the aim of identifying or clarifying the relationships between them. These techniques have been broadly classified as dependence techniques, which explore the relationship between one or more dependent variables and their independent predictors, and interdependence techniques, that make no such distinction but treat all variables equally in a search for underlying relationships. Multiple linear regression models a situation where a single numerical dependent variable is to be predicted from multiple numerical independent variables. Logistic regression is used when the outcome variable is dichotomous in nature. The log-linear technique models count type of data and can be used to analyze cross-tabulations where more than two variables are included. Analysis of covariance is an extension of analysis of variance (ANOVA), in which an additional independent variable of interest, the covariate, is brought into the analysis. It tries to examine whether a difference persists after "controlling" for the effect of the covariate that can impact the numerical dependent variable of interest. Multivariate analysis of variance (MANOVA) is a multivariate extension of ANOVA used when multiple numerical dependent variables have to be incorporated in the analysis. Interdependence techniques are more commonly applied to psychometrics, social sciences and market research. Exploratory factor analysis and principal component analysis are related techniques that seek to extract from a larger number of metric variables, a smaller number of composite factors or components, which are linearly related to the original variables. Cluster analysis aims to identify, in a large number of cases, relatively homogeneous groups called clusters, without prior information about the groups. The calculation intensive nature of multivariate analysis has so far precluded most researchers from using these techniques routinely. The situation is now changing with wider availability, and increasing sophistication of statistical software and researchers should no longer shy away from exploring the applications of multivariate methods to real-life data sets.

Project description:BACKGROUND:Implementation research is increasingly being recognised as an important discipline seeking to maximise the benefits of evidence-based interventions. Although capacity-building efforts are ongoing, there has been limited attention on the contextual and health system peculiarities in low- and middle-income countries. Moreover, given the challenges encountered during the implementation of health interventions, the field of implementation research requires a creative attempt to build expertise for health researchers and practitioners simultaneously. With support from the Special Programme for Research and Training in Tropical Diseases, we have developed an implementation research short course that targets both researchers and practitioners. This paper seeks to explain the course development processes and report on training evaluations, highlighting its relevance for inter-institutional and inter-regional capacity strengthening. METHODS:The development of the implementation research course curriculum was categorised into four phases, namely the formation of a core curriculum development team, course content development, internal reviews and pilot, and external reviews and evaluations. Five modules were developed covering Introduction to implementation research, Methods in implementation research, Ethics and quality management in implementation research, Community and stakeholder engagement, and Dissemination in implementation research. Course evaluations were conducted using developed tools measuring participants' reactions and learning. RESULTS:From 2016 to 2018, the IR curriculum has been used to train a total of 165 researchers and practitioners predominantly from African countries, the majority of whom are males (57%) and researchers/academics (79.4%). Participants generally gave positive ratings (e.g. integration of concepts) for their reactions to the training. Under 'learnings', participants indicated improvement in their knowledge in areas such as identification of implementation research problems and questions. CONCLUSION:The approach for training both researchers and practitioners offers a dynamic opportunity for the acquisition and sharing of knowledge for both categories of learners. This approach was crucial in demonstrating a key characteristic of implementation research (e.g. multidisciplinary) practically evident during the training sessions. Using such a model to effectively train participants from various low- and middle-income countries shows the opportunities this training curriculum offers as a capacity-building tool.

Project description:Abstract Advances in omics technologies alone are not a guarantee that science will translate to robust responsible innovation that is firmly grounded in societal values. This study aimed to identify best practices for Ethical, Legal, and Social Implications (ELSI) research in Africa that allows for optimal integration of community perspectives into the design and implementation of genomics research. In a large sample of 346 stakeholders in Cameroon, Ghana, and Tanzania (59% women), we used a qualitative study design with a phenomenological approach and conducted 32 group and 74 individual interviews (25% rural). We imported interview recordings into NVivo software for analysis. We created a “concept map” to organize the coded information, with Perspectives on Genomics and Sickle Cell Disease (SCD) Public Health Interventions as the central themes. We found that (1) analyses of major subthemes across and within countries revealed differential knowledge and experiences of SCD, and perspectives on various aspects of research and genomics; (2) we were able to gather empirical data efficiently from urban and rural stakeholders, to study the issues related to sample sharing, consent processes, and return of clinical and genomic study results; (3) the concept of nondirectiveness in modern genetic medicine practice can be challenged by the views of stakeholders in the context of a high-burden disease such as SCD; and (4) linking community views to current and proposed public health interventions could be understood within the context of each specific country. Our work informs future qualitative social science and technology policy research designs on genomics applications in Africa.

Project description:IntroductionA research-practice gap exists between what is known about conducting methodologically rigorous randomized controlled trials (RCTs) and what is done. Evidence consistently shows that pediatric RCTs are susceptible to high risk of bias; therefore novel methods of influencing the design and conduct of trials are required. The objective of this study was to develop and pilot test a wiki designed to educate pediatric trialists and trainees in the principles involved in minimizing risk of bias in RCTs. The focus was on preliminary usability testing of the wiki.MethodsThe wiki was developed through adaptation of existing knowledge translation strategies and through tailoring the site to the identified needs of the end-users. The wiki was evaluated for usability and user preferences regarding the content and formatting. Semi-structured interviews were conducted with 15 trialists and systematic reviewers, representing varying levels of experience with risk of bias or the conduct of trials. Data were analyzed using content analysis.ResultsParticipants found the wiki to be well organized, easy to use, and straightforward to navigate. Suggestions for improvement tended to focus on clarification of the text or on esthetics, rather than on the content or format. Participants liked the additional features of the site that were supplementary to the text, such as the interactive examples, and the components that focused on practical applications, adding relevance to the theory presented. While the site could be used by both trialists and systematic reviewers, the lack of a clearly defined target audience caused some confusion among participants.ConclusionsParticipants were supportive of using a wiki as a novel educational tool. The results of this pilot test will be used to refine the risk of bias wiki, which holds promise as a knowledge translation intervention for education in medical research methodology.

Project description:OBJECTIVES:'Growing Up in Australia: The Longitudinal Study of Australian Children' (LSAC) is Australia's only nationally representative children's longitudinal study, focusing on social, economic, physical and cultural impacts on health, learning, social and cognitive development. LSAC's first decade collected wide-ranging repeated psychosocial and administrative data; here, we describe the Child Health CheckPoint, LSAC's dedicated biophysical module. DESIGN, SETTING AND PARTICIPANTS:LSAC recruited a cross-sequential sample of 5107 infants aged 0-1 year and a sample of 4983 children aged 4-5 years in 2004, since completing seven biennial visits. CheckPoint was a cross-sectional wave that travelled Australia in 2015-2016 to reach LSAC's younger cohort at ages 11-12 years between LSAC waves 6 and 7. Parent-child pairs participated in comprehensive assessments at 15 Assessment Centres nationwide or, if unable to attend, a shorter home visit. MEASURES:CheckPoint's intergenerational, multidimensional measures were prioritised to show meaningful variation within normal ranges and capture non-communicable disease (NCD) phenotype precursors. These included anthropometry, physical activity, fitness, time use, vision, hearing, and cardiovascular, respiratory and bone health. Biospecimens included blood, saliva, buccal swabs (also from second parent), urine, hair and toenails. The epidemiology and parent-child concordance of many measures are described in separate papers. RESULTS:1874 (54% of eligible) parent-child pairs and 1051 second parents participated. Participants' geographical distribution mirrored the broader Australian population; however, mean socioeconomic position and parental education were higher and fewer reported non-English-speaking or Indigenous backgrounds. Application of survey weights partially mitigates that the achieved sample is less population representative than previous waves of LSAC due to non-random attrition. Completeness was uniformly high for phenotypic data (>92% of eligible), biospecimens (74%-97%) and consent (genetic analyses 98%, accessing neonatal blood spots 97%, sharing 96%). CONCLUSIONS:CheckPoint enriches LSAC to study how NCDs develop at the molecular and phenotypic levels before overt disease emerges, and clarify the underlying dimensionality of health in childhood and mid-adulthood.

Project description:BackgroundCurrently, thanks to the growing number of public database resources, most evidence on planning and management, healthcare institutions, policies and practices is becoming available to everyone. However, one of the limitations for the advancement of data and literature-driven research has been the lack of flexibility of the methodological resources used in qualitative research. There is a need to incorporate friendly, cheaper and faster tools for the systematic, unbiased analysis of large data corpora, in particular regarding the qualitative aspects of the information (often overlooked).MethodsThis article proposes a series of novel techniques, exemplified by the case of the role of Institutional Committees of Bioethics to (1) massively identify the documents relevant to a given issue, (2) extract the fundamental content, focusing on qualitative analysis, (3) synthesize the findings in the published literature, (4) categorize and visualize the evidence, and (5) analyse and report the results.ResultsA critical study of the institutional role of public health policies and practices in Institutional Committees of Bioethics was used as an example application of the method. Interactive strategies were helpful to define and conceptualise variables, propose research questions and refine research interpretation. These methods are additional aids to systematic reviews, pre-coding schemes and construction of a priori diagrams to survey and analyse social science literature.ConclusionsThese novel methods have proven to facilitate the formulation and testing of hypotheses on the subjects to be studied. Such tools may allow important advances going from descriptive approaches to decision-making and even institutional assessment and policy redesign, by pragmatic reason of time and costs.

Project description:Patient and public involvement (PPI) can be used in methods research, as well as applied research, in health economics. However, methods research goals may seem quite abstract when compared to the lived experiences of lay participants. This article draws on 4 years of PPI in a research project to develop methods for including family carer outcomes in economic evaluation. Key challenges in using PPI for health economics methods research relate to (1) training and preparation, (2) maintaining involvement, and (3) selecting suitable tasks. We suggest three criteria for selecting a research task for PPI input based on task importance, professional researcher skills gap, and potential PPI contribution.

Project description:Undertaking projects with European partners is an enterprising and rewarding activity, where societies can start to learn how to transfer knowledge and take advantage of best practices to further the benefits to health and social care service users. However, this can also be a challenging experience, more so when there is scanty guidance about the best way to conduct European partnership research. Using an on-going study of integrated care for older persons as an example (the PROCARE project), this paper provides an account of the methodological strengths and challenges of the qualitative approach used. It suggests that factors assisting a rigorous approach include sound and inclusive coordination, a strong research design, the construction of universally acceptable selection criteria, detailed interview schedules, and a transversal approach to data analysis.

Project description:ObjectivesA rapid review is a form of evidence synthesis considered a resource-efficient alternative to the conventional systematic review. Despite a dramatic rise in the number of rapid reviews commissioned and conducted in response to the coronavirus disease 2019 pandemic, published evidence on the optimal methods of planning, doing, and sharing the results of these reviews is lacking. The Priority III study aimed to identify the top 10 unanswered questions on rapid review methodology to be addressed by future research.Study design and settingA modified James Lind Alliance Priority Setting Partnership approach was adopted. This approach used two online surveys and a virtual prioritization workshop with patients and the public, reviewers, researchers, clinicians, policymakers, and funders to identify and prioritize unanswered questions.ResultsPatients and the public, researchers, reviewers, clinicians, policymakers, and funders identified and prioritized the top 10 unanswered research questions about rapid review methodology. Priorities were identified throughout the entire review process, from stakeholder involvement and formulating the question, to the methods of a systematic review that are appropriate to use, through to the dissemination of results.ConclusionThe results of the Priority III study will inform the future research agenda on rapid review methodology. We hope this will enhance the quality of evidence produced by rapid reviews, which will ultimately inform decision-making in the context of healthcare.

Project description:BackgroundHealth research capacity strengthening (RCS) projects are often complex and hard to evaluate. In order to inform health RCS evaluation efforts, we aimed to describe and compare key characteristics of existing health RCS evaluation frameworks: their process of development, purpose, target users, structure, content and coverage of important evaluation issues. A secondary objective was to explore what use had been made of the ESSENCE framework, which attempts to address one such issue: harmonising the evaluation requirements of different funders.MethodsWe identified and analysed health RCS evaluation frameworks published by seven funding agencies between 2004 and 2012, using a mixed methods approach involving structured qualitative analyses of documents, a stakeholder survey and consultations with key contacts in health RCS funding agencies.ResultsThe frameworks were intended for use predominantly by the organisations themselves, and most were oriented primarily towards funders' internal organisational performance requirements. The frameworks made limited reference to theories that specifically concern RCS. Generic devices, such as logical frameworks, were typically used to document activities, outputs and outcomes, but with little emphasis on exploring underlying assumptions or contextual constraints. Usage of the ESSENCE framework appeared limited.ConclusionsWe believe that there is scope for improving frameworks through the incorporation of more accessible information about how to do evaluation in practice; greater involvement of stakeholders, following evaluation capacity building principles; greater emphasis on explaining underlying rationales of frameworks; and structuring frameworks so that they separate generic and project-specific aspects of health RCS evaluation. The third and fourth of these improvements might assist harmonisation.
