The increased demand for evidence-based health care practices calls for comparative effectiveness research (CER), namely the generation and synthesis of research evidence to compare the benefits and harms of alternative methods of care. A significant contribution of CER is the systematic identification and synthesis of available research studies on a specific topic. The purpose of this article is to provide an overview of methodological issues pertaining to systematic reviews and meta-analyses to be used by investigators with the purpose of conducting CER. A systematic review or meta-analysis is guided by a research protocol, which includes (a) the research question, (b) inclusion and exclusion criteria with respect to the target population and studies, © guidelines for obtaining relevant studies, (d) methods for data extraction and coding, (e) methods for data synthesis, and (f ) guidelines for reporting results and assessing for bias. This article presents an algorithm for generating evidence-based knowledge by systematically identifying, retrieving, and synthesizing large bodies of research studies. Recommendations for evaluating the strength of evidence, interpreting findings, and discussing clinical applicability are offered.

Comparative effectiveness research (CER) seeks to assist consumers, clinicians, purchasers, and policy makers to make informed decisions to improve health care at both the individual and population levels. CER includes evidence generation and evidence synthesis. Randomized controlled trials are central to CER because of the lack of selection bias, with the recent development of adaptive and pragmatic trials increasing their relevance to real-world decision making. Observational studies comprise a growing proportion of CER because of their efficiency, generalizability to clinical practice, and ability to examine differences in effectiveness across patient subgroups. Concerns about selection bias in observational studies can be mitigated by measuring potential confounders and analytic approaches, including multivariable regression, propensity score analysis, and instrumental variable analysis. Evidence synthesis methods include systematic reviews and decision models. Systematic reviews are a major component of evidence-based medicine and can be adapted to CER by broadening the types of studies included and examining the full range of benefits and harms of alternative interventions. Decision models are particularly suited to CER, because they make quantitative estimates of expected outcomes based on data from a range of sources. These estimates can be tailored to patient characteristics and can include economic outcomes to assess cost effectiveness. The choice of method for CER is driven by the relative weight placed on concerns about selection bias and generalizability, as well as pragmatic concerns related to data availability and timing. Value of information methods can identify priority areas for investigation and inform research methods.

PurposeThe objectives of this article are (1) to examine the similarities and differences between comparative effectiveness research (CER) and evidence-based medicine (EBM); (2) to describe the implications of CER for systematic review methodologies in oncology; and (3) to address the transition from systematic reviews to guideline development and the implications of CER in this process.MethodAn analysis of the principles and methods of CER was undertaken in light of EBM, systematic reviews, and guidelines.Results and ConclusionThere is considerable overlap between the principles and methods of the two paradigms. The focus on best care options in the context of routine practice is a more central tenet of the CER paradigm. Thus, its value is not that it is the first paradigm to recognize the importance of a patient-focused approach in the research community, but rather, given the attention it has garnered, the CER paradigm may be precisely the reminder and push required to: one, influence how systematic questions are framed so that a more patient-relevant perspective is achieved; two, broaden the types of study designs that are valued and to include those, such as pragmatic trials and observational studies, that are better able to answer effectiveness questions; three, accelerate the development and application of statistical methods that enable indirect comparisons of cancer care options; and four, create clinical practice guidelines that are better positioned to improve quality of care and system performance. Over time, we will see if the CER paradigm lives up to its potential.
