Systematic literature review methods

With the exception of gender, few demographic data (e.g, about race/ethnicity, socioeconomic status, education, and urban/rural residency) were available. Definitions of consent were not always consistent and have changed over time, which not only limits our ability to compare studies but also may affect our evaluation of older studies given today's ethical standards for biobanking governance. Regardless of the assigned quality score, we included all studies in this review. We report the relevant findings based on the terminology, percentages, and number of significant digits as presented in the publications. The ultimate goal of this literature review and the eMERGE CERC survey is to obtain a more comprehensive understanding of public opinion about broad consent for data sharing and use. Systematic Reviews: the process: Types of Reviews. Literature review. by using systematic review methods to search and critically appraise existing research. Gender is the only demographic for which there is essentially complete information. DFID Education Rigorous Literature This includes developing methods for systematic Find out more about how the EPPI-Centre can help to support your review. Methods: We conducted a systematic literature review of attitudes toward biobanking, broad consent, and data sharing. This systematic literature review, What is equally striking are the large gaps in what is known about factors that affect people's decisions. For many studies, we were unable to ascertain the appropriateness of study questions or an analysis plan, thus limiting our ability to thoroughly assess the quality of the studies. Of these, just over half (51.3%) of participants identified as white, and 13.6% were African American and 6.3% were Hispanic/Latino. Some analyzed the actual choice that participants made when enrolling in research. do my assignment online 3d pool games Few studies reported the correlation between demographic variables and respondents' opinions. 3 Writing a Systematic Literature Review: Resources for Students and Trainees PROSPERO: University of York Centre for Reviews and Dissemination

Willingness to share in national databases or federal repositories. Representation of Asian participants was particularly low at 1.4%. Third, the studies that have been conducted to date have a number of limitations, which in turn limit the generalizability of this literature review. Searches were limited to the literature published since 1990 to capture current views about biobanking. A. G. and E. Systematic narrative review methods are a hybrid method of systematic literature searching combined with narrative syntheses and analyses. Handbook for Conducting a Literature-Based Health Assessment Using OHAT Approach for Systematic Review and Evidence Integration. January 9, 2015 In one study, 18.5% of 4,050 Vanderbilt University faculty and staff were more likely to want to participate in their institution's biobank if the de-identified data were deposited into a national database; however, 12.1% were less likely to want to participate.42 In many studies, the location of the repository was often important. Environmental Flows Can Reduce the Encroachment of Terrestrial Vegetation into River Channels: A Systematic Literature Review Scott et al.39 reported the results of a 1998 survey of blood donors that asked about their views regarding storage and use of the blood for research. We identified and screened a total of 3,205 citations and abstracts through the electronic database searches and manual review of articles and bibliographies (Figure 1). W. C.) assessed the quality of studies using questions adapted from published criteria for the quality assessment of survey and focus group studies.12,13,14 Scoring criteria fell into the following broad domains: (i) description of the methods, (ii) participant recruitment from a representative pool and response rates, (iii) appropriateness of objective study questions, and (iv) data analysis lending to reproducible results. And so on. Investigators used a variety of approaches to ascertain support for broad consent. In a focus group study in Boston, patients with breast cancer were generally positive about having their samples used for secondary studies that were not planned at the time they gave consent.22 One older survey deserves special comment. The reviewers independently assessed each article and resolved disagreements via discussion to reach consensus.

Systematic literature review methods

We excluded commentaries and one dissertation from which data could not be extracted. Only 21 studies reported socioeconomic status, and 43 reported educational level. The first is under what conditions data can and should be repurposed for other research in order to increase what can be learned from them. Debates have also addressed what sort of control, if any, individuals ought to have over the sharing of data obtained from them, with a similar array of options.6,8,9 Each option has proponents who present ethical, legal, and social arguments for their positions, often citing studies of public opinion.10,11 This raises the question of what impact public opinion should have on the development of public policy in this arena. TECHNICAL REPORT Systematic literature review to examine the evidence for the effectiveness of interventions that use theories and models of behaviour change: Mixed-Methods Systematic Reviews: Integrating Quantitative and Qualitative Findings. mixed-methods reviews reviewing the literature, and a systematic review is Systematic Reviews encompasses all aspects of the design, conduct and reporting of systematic reviews. The journal publishes high quality systematic review products Twenty-eight studies were conducted primarily in urban settings, two were conducted in rural settings, nine were conducted in both urban and rural settings, and nine studies were conducted nationwide. The studies included here typically noted a general acceptance for broad consent and endorsement of data sharing, but with notable privacy and governance concerns, especially by minority participants. quantitative statistical methods. systematic literature review or a meta-analysis are unduly influenced by a small Undertaking systematic reviews Home; Types of literature review & methods; Protocol and registration; Search strategy; Medical Literature Databases to search; Study selection and appraisal Nonetheless, questions remain about the ethical and practical desirability and acceptability of broad consent for research and data sharing. James Hardiman Library. Guidance notes on planning a systematic review. In contrast to the traditional or narrative literature review, systematic literature.. This review also was limited to the United States, which is warranted given the different policy preferences in other countries. In 2013, the NIH asked the Consent, Education, Regulation, and Consultation (CERC) Working Group of the Electronic Medical Records and Genomics (eMERGE) Network to conduct a population-based survey of public opinion about the acceptability of both broad consent for research and wide data sharing.

We qualitatively analyzed results of studies using summary tables and descriptive synthesis. These data are often placed in biobanks or biorepositories, which may exist at both the site(s) of collection and in aggregated or centralized sites, such as the database of Genotypes and Phenotypes. Disagreements between reviewers were resolved by discussion that included a third reviewer (A. We also manually searched the reference lists of included studies and of recent narrative and systematic reviews addressing the topic. We defined broad consent as a process in which participants agree prospectively to have their samples, genomic data, and health information retained for use in any future research deemed appropriate by a biobank and/or relevant oversight bodies. Thus, while we used multiple approaches (e.g, searching multiple sources, reviewing reference lists, and searching the unpublished, gray literature, such as dissertations and reports) to comprehensively identify studies, we may not have identified all salient research. This systematic literature review, which ultimately contained 48 studies involving 35,969 participants, was conducted to identify gaps and issues that needed to be addressed in this survey. The questions used in the quality review are contained in Supplementary Table S2 online. Two publications used a mixed-methods approach that included qualitative studies that informed the development and implementation of a survey.35,45 Nineteen studies were of good quality, 27 of fair quality, and 2 of poor quality. http://howidoit.ning.com/profiles/blogs/do-my-homework-for-me-website-philippines Preferences for opt-out or opt-in.

Some of the studies published after 2011 mention the ANPRM.46,56,59,65 Although we examined studies published since 1990, no studies that met our inclusion criteria were published before 2001. The willingness of patients with cancer to share seemed to be shaped by their devotion to the institution at which they were receiving care. i don't wanna write my paper 60 lb Asking participants for their preference among different types of consent-broad, study-by-study, or categorical consent-revealed more mixed support for broad consent.

Categorical consent, by contrast, is a process in which participants agree prospectively to future use of their samples and data for particular types of research, usually by categories of disease (e.g, cardiac diseases, diabetes). Reviewers' Manual Methodology for JBI Mixed Methods Systematic Reviews 7 Rather, the majority either develop a framework based on themes derived from qualitative Many studies did not report other demographic data. Articles were included if they reported empirical data with sufficient detail to enable use and aggregation of the data and results about individuals in the United States regarding one or more of the following: participant perceptions of broad consent or data sharing for biobank research, preferences for different consent models for biobank research, information about people's opinions about participating in biobank research, or providing broad consent for biobank research. Roughly one-third of the studies (n = 20) were written and published after the Office of Human Research Protections issued the ANPRM in July 2011.46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65 The number of studies published per year from 2008 to 2014 ranged from five to seven, with no notable difference after the ANPRM was issued. Two investigators (N. Studies of broad consent may use an opt-in or an opt-out model. Click here! Search strategies used subject heading terms appropriate for each database and key words relevant to biobanking, consent, and data sharing (Supplementary Table S1 online). Details for gender were available for 93.3% of participants. Willingness to give broad consent increased if data were de-identified.
Even when demographic information was obtained, investigators did not always report how these variables correlated with respondents' opinions. 5 Unit One: Background to Systematic Reviews Learning Objectives To understand the terms ‘systematic review' and ‘meta‐analysis' A total of 51 publications comprising 48 studies were included in this review.15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65 Most studies involved surveys (n = 23), followed by focus groups (n = 8), mixed methods (n = 14), interviews (n = 1), and analyses of consent forms (n = 2) (Supplementary Table S3 online). Identifiability of samples influences the acceptability of broad consent. Systematic review methods (SRM) offer possibilities for increasing the rigor of reviews of the literature. SRM have been widely adopted in the health Buy essay. These facts raise two distinct, but related, questions. The policy question will be what to do if some people, particularly from certain demographics, express a desire for more granular control over the use of data obtained from them in light of the policy trend toward requiring individual consent for broad data use and sharing. One study reported that participants who were significantly more likely to prefer broad consent also believed that participating would make me feel like I was contributing to society (odds ratio = 1.85; P = 0.001), that the study would accelerate medical treatments and cures (odds ratio = 2.20; P = 0.001), and that participating in the cohort study would be easy (odds ratio = 1.59; P < 0.001).59 Other investigators reported that the large majority (97.7%) of respondents said yes or maybe to the idea that it is a gift to society when an individual takes part in medical research.46 Many other studies cited the benefit of research to improve health as a reason to favor broad consent. Two reviewers (N.
