Book excerpt: The identification of gaps from systematic reviews is essential to the practice of ''evidence-based research.'' Health care research should begin and end with a systematic review. A comprehensive and explicit consideration of the existing evidence is necessary for the identification and development of an unanswered and answerable question, for the design of a study most likely to answer that question, and for the interpretation of the results of the study. In a systematic review, the consideration of existing evidence often highlights important areas where deficiencies in information limit our ability to make decisions. We define a research gap as a topic or area for which missing or inadequate information limits the ability of reviewers to reach a conclusion for a given question. A research gap may be further developed, such as through stakeholder engagement in prioritization, into research needs. Research needs are those areas where the gaps in the evidence limit decision making by patients, clinicians, and policy makers. A research gap may not be a research need if filling the gap would not be of use to stakeholders that make decisions in health care. The clear and explicit identification of research gaps is a necessary step in developing a research agenda. Evidence reports produced by Evidence-based Practice Centers (EPCs) have always included a future research section. However, in contrast to the explicit and transparent steps taken in the completion of a systematic review, there has not been a systematic process for the identification of research gaps. We developed a framework to systematically identify research gaps from systematic reviews. This framework facilitates the classification of where the current evidence falls short and why the evidence falls short. The framework included two elements: (1) the characterization the gaps and (2) the identification and classification of the reason(s) for the research gap. The PICOS structure (Population, Intervention, Comparison, Outcome and Setting) was used in this framework to describe questions or parts of questions inadequately addressed by the evidence synthesized in the systematic review. The issue of timing, sometimes included as PICOTS, was considered separately for Intervention, Comparison, and Outcome. The PICOS elements were the only sort of framework we had identified in an audit of existing methods for the identification of gaps used by EPCs and other related organizations (i.e., health technology assessment organizations). We chose to use this structure as it is one familiar to EPCs, and others, in developing questions. It is not only important to identify research gaps but also to determine how the evidence falls short, in order to maximally inform researchers, policy makers, and funders on the types of questions that need to be addressed and the types of studies needed to address these questions. Thus, the second element of the framework was the classification of the reasons for the existence of a research gap. For each research gap, the reason(s) that most preclude conclusions from being made in the systematic review is chosen by the review team completing the framework. To leverage work already being completed by review teams, we mapped the reasons for research gaps to concepts from commonly used evidence grading systems. Our objective in this project was to complete two types of further evaluation: (1) application of the framework across a larger sample of existing systematic reviews in different topic areas, and (2) implementation of the framework by EPCs. These two objectives were used to evaluate the framework and instructions for usability and to evaluate the application of the framework by others, outside of our EPC, including as part of the process of completing an EPC report. Our overall goal was to produce a revised framework with guidance that could be used by EPCs to explicitly identify research gaps from systematic reviews.

However, in contrast to the methods of the systematic review, future needs are not identified systematically. There is limited literature describing organizing principles or frameworks for determining research gaps. We developed and pilot-tested a framework for the identification of research gaps from systematic reviews. STUDY DESIGN: We reviewed the research gaps identification practices of organizations involved with evidence synthesis. We contacted: (i) evidence-based practice centers (EPCs) (n=12) associated with the Agency for Healthcare Research and Quality (AHRQ) in the US and Canada, and (ii) other organizations around the world (n=64) that conduct systematic reviews, cost-effectiveness analyses, or technology assessments. Based on the responses, we developed a framework for identifying research gaps. We obtained feedback from two technical experts at our institution and pilot-tested this framework on two randomly selected EPC evidence reports. We also developed a simple, user-friendly worksheet with instructions to facilitate the use of the framework by investigators during or after a systematic review. POPULATION STUDIED: Not Applicable. PRINCIPAL FINDINGS: Four (33.3%) EPCs and 3 (8.1%) of the other organizations reported currently using an explicit framework to determine research gaps. We did not identify one framework that captured all elements needed to determine and characterize research gaps. Variations of the PICO (population, intervention, comparison, outcomes) framework were most common. It is also important to classify the reason(s) for the gap to help determine how to address the gap. Therefore, we propose a framework that includes both the characterization of the gap using PICOS elements (also including setting) and the identification of the reason(s) why the gap exists. The framework allows investigators to classify reasons for the existence of a research gap as: (a) insufficient or imprecise information, (b) biased information; (c) inconsistency or unknown consistency, and (d) not the right information. We mapped each of these reasons to concepts from three commonly used evidence grading systems: the Grading of Recommendations Assessment, Development and Evaluation (GRADE); the United States Preventive Services Task Force (USPSTF); and the Strength of Evidence (SOE) used by EPCs. This allows leveraging of work already being completed during evidence grading. During pilot-testing, we identified challenges including difficulty in applying the framework for completed systematic reviews and differences in the specificity of research gaps abstracted by different users. These could be tackled with a priori discussions amongst investigators. Further testing should determine if these challenges are ameliorated if the framework is used during a systematic review. CONCLUSIONS: We developed a framework to identify and characterize research gaps from systematic reviews. The framework provides for the classification of where and why the current evidence falls short. IMPLICATIONS FOR POLICY, DELIVERY, OR PRACTICE: In synthesizing evidence, systematic reviews inform health-care decisions for patients, policymakers, and clinicians. Systematic reviews can also be invaluable for identifying research gaps, thus helping develop research agendas. This potential impact of systematic reviews has not been realized. Our framework provides for systematically identifying and characterizing research gaps from systematic reviews. This explicit identification of research gaps will help determine the type of research needed to address the goals of comparative effectiveness research.

Book excerpt: BACKGROUND: Research gaps prevent systematic reviewers from making conclusions and, ultimately, limit our ability to make informed health care decisions. While there are well-defined methods for conducting a systematic review, there has been no explicit process for the identification of research gaps from systematic reviews. In a prior project we developed a framework to facilitate the systematic identification and characterization of research gaps from systematic reviews. This framework uses elements of PICOS (Population, Intervention, Comparison, Outcomes, Setting) to describe the gaps and categorizes the reasons for the gaps as (A) insufficient or imprecise information, (B) biased information, (C) inconsistent or unknown consistency results, and/or (D) not the right information. OBJECTIVE: To further develop and evaluate a framework for the identification and characterization of research gaps from systematic reviews. METHODS: We conducted two types of evaluation: (1) We applied the framework to existing systematic reviews, and (2) Evidence-based Practice Centers (EPCs) applied the framework either during a systematic review or during a future research needs project (FRN). EPCs provided feedback on the framework using an evaluation form. RESULTS: Our application of the framework to 50 systematic reviews identified about 600 unique research gaps. Key issues emerging from this evaluation included the need to clarify instructions for dealing with multiple comparisons (lumping vs. splitting) and need for guidance on applying the framework retrospectively. We received evaluation forms from seven EPCs. EPCs applied the framework in 8 projects, five of which were FRNs. Challenges identified by the EPCs led to revisions in the instructions including guidance for teams to decide a priori whether to limit the use of the framework to questions for which strength of evidence has been assessed, and the level of detail needed for the characterization of the gaps. CONCLUSIONS: Our team evaluated a revised framework, and developed guidance for its application. A final version is provided that incorporates revisions based on use of the framework across existing systematic reviews and feedback from other EPCs on their use of the framework. Future research is needed to evaluate the relative costs and benefits of using the framework, for review authors and for users of the systematic reviews.

Available in PDF, EPUB and Kindle. Book excerpt: Healthcare decision makers in search of reliable information that compares health interventions increasingly turn to systematic reviews for the best summary of the evidence. Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies, and can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. Systematic reviews can be helpful for clinicians who want to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines. Too often systematic reviews are of uncertain or poor quality. There are no universally accepted standards for developing systematic reviews leading to variability in how conflicts of interest and biases are handled, how evidence is appraised, and the overall scientific rigor of the process. In Finding What Works in Health Care the Institute of Medicine (IOM) recommends 21 standards for developing high-quality systematic reviews of comparative effectiveness research. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. Finding What Works in Health Care also proposes a framework for improving the quality of the science underpinning systematic reviews. This book will serve as a vital resource for both sponsors and producers of systematic reviews of comparative effectiveness research.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: OBJECTIVES: Systematic reviews are currently used by only a minority of researchers to inform the design of research studies. This may lead to inefficient and potentially wasteful research. We aimed to develop a framework which clinical researchers can apply to existing systematic reviews in order to effectively inform the design of proposed new clinical research studies. DATA SOURCES: Published frameworks or models designed to use results of systematic reviews or meta-analyses in new research study design. REVIEW METHODS: A multiphase iterative process was used to develop the framework. Phase 1 involved a focused literature search to identify existing frameworks and processes that have been proposed as methods to identify research gaps by systematic reviews. In phase 2, we convened a multidisciplinary group with varied expertise to develop a stepwise framework. In phase 3, we identified two systematic reviews and applied this framework to their results. Phase 4 invited external opinions from additional experts to further refine the framework. RESULTS: We developed a four-step framework designed to be useable by primary researchers: Step 1 involves clearly laying out the crucial design elements of the proposed study using PICOTS (populations, interventions, comparators, outcomes, timing, and setting) elements. Step 2 provides a simple method to identify an existing systematic review which is current, valid, and relevant enough to the proposed research study to inform its design. In Step 3, the details of the systematic review are examined to determine the extent to which it has already addressed the questions proposed by the new study, and uses the PICOTS elements of the primary studies included in the systematic review to modify the design of the proposed study. Finally, Step 4 establishes the need (or otherwise) for the proposed study, and prioritizes modifications to the research design. CONCLUSIONS: The four-step framework proposes a practical method which can be used by clinical researchers who are not experts in systematic reviews to determine whether further research studies are needed and suggest ways that the primary literature identified by the systematic review can be used to modify the design of further research studies. Further research needs to determine how useful and practical this proposed framework is for researchers, and attempt to measure its value in modifying research designs and optimizing research efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.

This book was released on 2019-09-27 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: With U.S. health care costs projected to grow at an average rate of 5.5 percent per year from 2018 to 2027, or 0.8 percentage points faster than the gross domestic product, and reach nearly $6.0 trillion per year by 2027, policy makers and a wide range of stakeholders are searching for plausible actions the nation can take to slow this rise and keep health expenditures from consuming an ever greater portion of U.S. economic output. While health care services are essential to heath, there is growing recognition that social determinants of health are important influences on population health. Supporting this idea are estimates that while health care accounts for some 10 to 20 percent of the determinants of health, socioeconomic factors and factors related to the physical environment are estimated to account for up to 50 percent of the determinants of health. Challenges related to the social determinants of health at the individual level include housing insecurity and poor housing quality, food insecurity, limitations in access to transportation, and lack of social support. These social needs affect access to care and health care utilization as well as health outcomes. Health care systems have begun exploring ways to address non-medical, health-related social needs as a way to reduce health care costs. To explore the potential effect of addressing non-medical health-related social needs on improving population health and reducing health care spending in a value-driven health care delivery system, the National Academies of Science, Engineering, and Medicine held a full-day public workshop titled Investing in Interventions that Address Non-Medical, Health-Related Social Needs on April 26, 2019, in Washington, DC. The objectives of the workshop were to explore effective practices and the supporting evidence base for addressing the non-medical health-related social needs of individuals, such as housing and food insecurities; review assessments of return on investment (ROI) for payers, healthy systems, and communities; and identify gaps and opportunities for research and steps that could help to further the understanding of the ROI on addressing non-medical health-related social needs. This publication summarizes the presentations and discussions from the workshop.

Available in PDF, EPUB and Kindle. Book excerpt: There is currently heightened interest in optimizing health care through the generation of new knowledge on the effectiveness of health care services. The United States must substantially strengthen its capacity for assessing evidence on what is known and not known about "what works" in health care. Even the most sophisticated clinicians and consumers struggle to learn which care is appropriate and under what circumstances. Knowing What Works in Health Care looks at the three fundamental health care issues in the United States-setting priorities for evidence assessment, assessing evidence (systematic review), and developing evidence-based clinical practice guidelines-and how each of these contributes to the end goal of effective, practical health care systems. This book provides an overall vision and roadmap for improving how the nation uses scientific evidence to identify the most effective clinical services. Knowing What Works in Health Care gives private and public sector firms, consumers, health care professionals, benefit administrators, and others the authoritative, independent information required for making essential informed health care decisions.

Available in PDF, EPUB and Kindle. Book excerpt: Such diverse thinkers as Lao-Tze, Confucius, and U.S. Defense Secretary Donald Rumsfeld have all pointed out that we need to be able to tell the difference between real and assumed knowledge. The systematic review is a scientific tool that can help with this difficult task. It can help, for example, with appraising, summarising, and communicating the results and implications of otherwise unmanageable quantities of data. This book, written by two highly-respected social scientists, provides an overview of systematic literature review methods: Outlining the rationale and methods of systematic reviews; Giving worked examples from social science and other fields; Applying the practice to all social science disciplines; It requires no previous knowledge, but takes the reader through the process stage by stage; Drawing on examples from such diverse fields as psychology, criminology, education, transport, social welfare, public health, and housing and urban policy, among others. Including detailed sections on assessing the quality of both quantitative, and qualitative research; searching for evidence in the social sciences; meta-analytic and other methods of evidence synthesis; publication bias; heterogeneity; and approaches to dissemination.

Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive major reference work for our SpringerReference program covering clinical trials. Although the core of the Work will focus on the design, analysis, and interpretation of scientific data from clinical trials, a broad spectrum of clinical trial application areas will be covered in detail. This is an important time to develop such a Work, as drug safety and efficacy emphasizes the Clinical Trials process. Because of an immense and growing international disease burden, pharmaceutical and biotechnology companies continue to develop new drugs. Clinical trials have also become extremely globalized in the past 15 years, with over 225,000 international trials ongoing at this point in time. Principles in Practice of Clinical Trials is truly an interdisciplinary that will be divided into the following areas: 1) Clinical Trials Basic Perspectives 2) Regulation and Oversight 3) Basic Trial Designs 4) Advanced Trial Designs 5) Analysis 6) Trial Publication 7) Topics Related Specific Populations and Legal Aspects of Clinical Trials The Work is designed to be comprised of 175 chapters and approximately 2500 pages. The Work will be oriented like many of our SpringerReference Handbooks, presenting detailed and comprehensive expository chapters on broad subjects. The Editors are major figures in the field of clinical trials, and both have written textbooks on the topic. There will also be a slate of 7-8 renowned associate editors that will edit individual sections of the Reference.
