Ethical considerations of conducting systematic reviews in educational research are not typically discussed explicitly. However, systematic reviews are frequently read and cited in documents that influence educational policy and practice. Hence, ethical issues associated with what and how systematic reviews are produced and used have serious implications. It becomes imperative for systematic reviewers to reflexively engage with a variety of ethical issues associated with potential conflicts of interest and issues of voice and representation. This chapter discusses how systematic reviewers can draw upon the philosophical traditions of consequentialism, deontology or virtue ethics to situate their ethical decision-making.

Methodological Approaches to Literature Review

Ethical considerations of conducting systematic reviews in educational research are not typically discussed explicitly. As an illustration, ‘ethics’ is not listed as a term in the index of the second edition of ‘An Introduction to Systematic Reviews’ (Gough et al. 2017 ). This chapter draws from my earlier in-depth discussion of this topic in the Qualitative Research Journal (Suri 2008 ) along with more recent publications by colleagues in the field of research ethics and methods of research synthesis.

Unlike primary researchers, systematic reviewers do not collect deeply personal, sensitive or confidential information from participants. Systematic reviewers use publicly accessible documents as evidence and are seldom required to seek an institutional ethics approval before commencing a systematic review. Institutional Review Boards for ethical conduct of research do not typically include guidelines for systematic reviews. Nonetheless, in the past four decades systematic reviews have evolved to become more methodologically inclusive and play a powerful role in influencing policy, practice, further research and public perception. Hence, ethical considerations of how interests of different stakeholders are represented in a research review have become critical (Franklin 1999 ; Hammersley 2003 ; Harlen and Crick 2004 ; Popkewitz 1999 ).

Educational researchers often draw upon the philosophical traditions of consequentialism, deontology or virtue ethics to situate their ethical decision-making. Consequentialism or utilitarianism focuses on maximising benefit and minimising harm by undertaking a cost-benefit analysis of potential positive and negative impacts of research on all stakeholders. Deontology or universalism stems from Immanuel Kant’s logic that certain actions are inherently right or wrong and hence ends cannot justify the means. A deontological viewpoint is underpinned by rights-based theories that emphasise universal adherence to the principles of beneficence (do good), non-maleficence (prevent harm), justice, honesty and gratitude. While both consequentialism and deontology focus on actions and behaviour, virtue ethics focuses on being virtuous, especially in relationships with various stakeholders. There are several overlaps, as well as tensions, between and across these philosophical traditions (Brooks et al. 2014 ; Cohen et al. 2018 ).

Recognising the inherently situated nature of ethical decision-making, I am selectively eclectic in drawing from each of these traditions. I discuss a variety of ethical considerations of conducting systematic reviews informed by rights-based theories, ethics of care and Foucauldian ethics. Rights-based theories underpin deontology and consequentialism. Most regulatory research ethics guidelines, such as those offered by British Educational Research Association (BERA 2018 ) and American Educational Research Association are premised on rights-based theories that emphasises basic human rights, such as liberty, equality and dignity. Ethics of care prioritises attentiveness, responsibility, competence and responsiveness (Tronto 2005 ). Foucauldian ethics highlights the relationship of power and knowledge (Ball 2013 ).

In my earlier publications, I have identified the following three guiding principles for a quality research synthesis (Suri 2018 ; Suri and Clarke 2009 ):

Informed subjectivity and reflexivity

Purposefully informed selective inclusivity

Audience-appropriate transparency

In the rest of this chapter, I will discuss how these guiding principles can support ethical decision making in systematic reviews in each of the following six phases of systematic reviews as identified in my earlier publications (Suri 2014 ):

identifying an appropriate epistemological orientation

identifying an appropriate purpose

searching for relevant literature

evaluating, interpreting and distilling evidence from selected reports

constructing connected understandings

communicating with an audience

To promote ethical production and use of systematic reviews through this chapter, I have used questioning as a strategic tool with the purpose of raising awareness about a variety of ethical considerations among systematic reviewers and their audience

1 Identifying an Appropriate Epistemological Orientation

What philosophical traditions are amenable for guiding ethical decision - making in systematic reviews positioned along distinct epistemologies?

Practising informed subjectivity and reflexivity, all systematic reviewers must identify an appropriate epistemological orientation, such as post-positivist, interpretive, participatory and/or critical, that is aligned with their review purpose and research competence (Suri 2013 , 2018 ).

Deontological ethics is more relevant to post-positivist reviewers who focus on explaining, predicting or describing educational phenomena as generalisable laws expressed through relationships between measurable constructs and variables. The ethical focus of post-positivist systematic reviews tends to be on minimising threats to internal validity, external validity, internal reliability and external reliability of review findings. This is typically achieve by using a priori synthesis protocols, defining all key constructs conceptually and operationally in behavioural terms, employing exhaustive sampling strategies and employing variable oriented statistical analyses (Matt and Cook 2009 ; Petticrew and Roberts 2006 ).

Teleological ethics is more relevant to interpretive systematic reviews aiming to construct a holistic understanding of the educational phenomena that takes into account subjective experiences of diverse groups in varied contexts. Ethical decision making in interpretive systematic reviews lays an emphasis on authentically representing experiences and perceptions of diverse groups, especially those whose viewpoints tend to be less represented in the literature, to the extent that is permissible from the published literature. Maintaining a questioning gaze and a genuine engagement with diverse viewpoints, interpretive systematic reviewers focus on how individual accounts of a phenomenon reinforce, refute or augment each other (Eisenhart 1998 ; Noblit and Hare 1988 ).

Ethics of care is amenable to participatory systematic reviews that are designed to improve participant reviewers’ local world experientially through critical engagement with the relevant research. Ethical decision making in participatory systematic reviews promotes building teams of practitioners with the purpose of co-reviewing research that can transform their own practices and representations of their lived experiences. Participant co-reviewers exercise greater control throughout the review process to ensure that the review remains relevant to generating actionable knowledge for transforming their practice (Bassett and McGibbon 2013 ).

Foucauldian ethics is aligned with critical systematic reviews that contest dominant discourse by problematizing the prevalent metanarratives. Ethical decision making in critical systematic reviews focuses on problematizing ‘what we might take for granted’ (Schwandt 1998 , p. 410) in a field of research by raising ‘important questions about how narratives get constructed, what they mean, how they regulate particular forms of moral and social experiences, and how they presuppose and embody particular epistemological and political views of the world’ (Aronowitz and Giroux 1991 , pp. 80–81).

2 Identifying an Appropriate Purpose

What are key ethical considerations associated with identifying an appropriate purpose for a systematic review?

In this age of information explosion, systematic reviews require substantial resources. Guided by teleological ethics, systematic reviewers must conduct a cost-benefit analysis with a critical consideration of the purpose and scope of the review and its potential benefits to various groups of stakeholders.

If we consider the number of views or downloads as a proxy measure of impact, then we can gain useful insights by examining the teleological underpinnings of some of the highly read systematic reviews. Review of Educational Research (RER) tends to be regarded as the premiere educational research review journal internationally. Let us examine the scope and purpose of the three ‘most read’ articles in RER, as listed on 26 September 2018. Given the finite amount of resources available, an important question for educators is ‘what interventions are likely to be most effective, and under what circumstances?’. The power of feedback (Hattie and Timperley 2007 ), with 11463 views and downloads, is a conceptual analysis primarily drawing from the findings of published systematic reviews (largely meta-analyses) conducted to address this important question. In addition to effectively teaching what is deemed important, educators also have an important role of critiquing what is deemed important and why. The theory and practice of culturally relevant education: A synthesis of research across content areas (Aronson and Laughter 2016 ), with 8958 views and downloads, is an example of such a systematic review. After highlighting the positive outcomes of culturally relevant education, the authors problematise the validity of standardised testing as an unbiased form of a desirable educational outcome for all. As education is essentially a social phenomenon, understanding how different stakeholders perceive various configurations of an educational intervention is critical. Making sense of assessment feedback in higher education (Evans 2013 ), with 5372 views and downloads, is an example of a systematic review that follows such a pursuit. Even though each of these reviews required significant resources and expertise, the cost is justified by the benefits evident from the high number of views and downloads of these articles. Each of these three reviews makes clear recommendations for practitioners and researchers by providing an overview, as well as interrogating, current practices.

All educational researchers are expected to prevent, or disclose and manage, ethical dilemmas arising from any real or perceived conflicts of interest (AERA 2011 ; BERA 2018 ). Systematic reviewers should also carefully scrutinise how their personal, professional or financial interests may influence the review findings in a specific direction. As systematic reviews require significant effort and resources, it is logical for systematic reviewers to bid for funding. Recognising the influence of systematic reviews in shaping perceptions of the wider community, many profit and not profit organisations have become open to funding systematic reviews. Before accepting funding for conducting a systematic review, educational researchers must carefully reflect on the following questions:

How does the agenda of the funding source intersect with the purpose of the review?

How might this potentially influence the review process and findings? How will this be managed ethically to ensure integrity of the systematic review findings?

In case of sponsored systematic reviews, it is important to consider at the outset how potential ethical issues will be managed if the interest of the funding agency conflicts with the interests of relatively less influential or less represented groups. Systematic reviews funded by a single agency with a vested interest in the findings are particularly vulnerable to ethical dilemmas arising from a conflict of interest (The Methods Coordinating Group of the Campbell Collaboration 2017 ). One approach could be to seek funding from a combination of agencies representing interests of different stakeholder groups. Exploring the option of crowdfunding is another option that systematic reviewers could use to represent the interests of marginalised groups whose interests are typically overlooked in the agenda of powerful funding agencies. In participatory synthesis, it is critical that the purpose of the systematic review evolves organically in response to the emerging needs of the practitioner participant reviewers.

3 Searching for Relevant Literature

What are key ethical considerations associated with developing an appropriate strategy for sampling and searching relevant primary research reports to include in a systematic review?

A number of researchers in education and health sciences have found that studies with certain methodological orientations or types of findings are more likely to be funded, published, cited and retrieved through common search channels (Petticrew and Roberts 2006 ). Serious ethical implications arise when systematic reviews of biased research are drawn upon to make policy decisions with an assumption that review findings are representative of the larger population. In designing an appropriate sampling and search strategy, systematic reviewers should carefully consider the impact of potential publication biases and search biases.

Funding bias, methodological bias, outcome bias and confirmatory bias are common forms of publication bias in educational research. For instance, studies with large sample-sizes are more likely to attract research funding, being submitted for publishing and getting published in reputable journals (Finfgeld-Connett and Johnson 2012 ). Research that reports significantly positive effects of an innovative intervention is more likely to be submitted for publishing by primary researchers and being accepted for publishing by journal editors (Dixon-Woods 2011 ; Rothstein et al. 2004 ). Rather than reporting on all the comparisons made in a study, often authors report on only those comparisons that are significant (Sutton 2009 ). As a result, the effectiveness of innovative educational interventions gets spuriously inflated in published literature. Often, when an educational intervention is piloted, additional resources are allocated for staff capacity building. However, in real life when the same intervention is rolled out at scale, the same degree of support is not provided to teachers whose practice is impacted by the intervention (Schoenfeld 2006 ).

Even after getting published, certain types of studies are more likely to be cited and retrieved through common search channels, such as key databases and professional networks (Petticrew and Roberts 2006 ). Systematic reviewers must carefully consider common forms of search biases, such as database bias, citation bias, availability bias, language bias, country bias, familiarity bias and multiple publication bias. The term ‘grey literature’ is sometimes used to refer to published and unpublished reports, such as government reports, that are not typically included in common research indexes and databases (Rothstein and Hopewell 2009 ). Several scholars recommend inclusion of grey literature to minimise potential impact of publication bias and search bias (Glass 2000 ) and to be inclusive of key policy documents and government reports (Godin et al. 2015 ). On the other hand, several other scholars argue that systematic reviewers should include only published research that has undergone the peer-review process of academic community to include only high-quality research and to minimise the potential impact of multiple publications based on the same dataset (La Paro and Pianta 2000 ).

With the ease of internet publishing and searching, the distinction between published and unpublished research has become blurred and the term grey literature has varied connotations. While most systematic reviews employ exhaustive sampling, in recent years there has been an increasing uptake of purposeful sampling in systematic reviews as evident from more than 1055 Google Scholar citations of a publication on this topic: Purposeful sampling in qualitative research synthesis (Suri 2011 ).

Aligned with the review’s epistemological and teleological positioning, all systematic reviewers must prudently design a sampling strategy and search plan, with complementary sources, that will give them access to most relevant primary research from a variety of high-quality sources that is inclusive of diverse viewpoints. They must ethically consider positioning of the research studies included in their sample in relation to the diverse contextual configurations and viewpoints commonly observed in practical settings.

4 Evaluating, Interpreting and Distilling Evidence from the Selected Research Reports

What are key ethical considerations associated with evaluating, interpreting and distilling evidence from the selected research reports in a systematic review?

Systematic reviewers typically do not have direct access to participants of primary research studies included in their review. The information they analyse is inevitably refracted through the subjective lens of authors of individual studies. It is important for systematic reviewers to critically reflect upon contextual position of the authors of primary research studies included in the review, their methodological and pedagogical orientations, assumptions they are making, and how they might have influenced the findings of the original studies. This becomes particularly important with global access to information where critical contextual information, that is common practice in a particular context but not necessarily in other contexts, may be taken-for-granted by the authors of the primary research report and hence may not get explicitly mentioned.

Systematic reviewers must ethically consider the quality and relevance of evidence reported in primary research reports with respect to the review purpose (Major and Savin-Baden 2010 ). In evaluating quality of evidence in individual reports, it is important to use the evaluation criteria that are commensurate with the epistemological positioning of the author of the study. Cook and Campbell’s ( 1979 ) constructs of internal validity, construct validity, external validity and statistical conclusion are amenable for evaluating postpositivist research. Valentine ( 2009 ) provides a comprehensive discussion of criteria suitable for evaluating research employing a wide range of postpositivist methods. Lincoln and Guba’s ( 1985 ) constructs of credibility, transferability, dependability and confirmability are suitable for evaluating interpretive research. The Centre for Reviews and Dissemination (CRD 2009 ) provides a useful comparison of common qualitative research appraisal tools in Chap.  6 of its open access guidelines for systematic reviews. Herons and Reason’s ( 1997 ) constructs of critical subjectivity, epistemic participation and political participation emphasising a congruence of experiential, presentational, propositional, and practical knowings are appropriate for evaluating participatory research studies. Validity of transgression, rather than correspondence, is suitable for evaluating critically oriented research reports using Lather’s constructs of ironic validity, paralogical validity, rhizomatic validity and voluptuous validity (Lather 1993 ). Rather than seeking perfect studies, systematic reviewers must ethically evaluate the extent to which findings reported in individual studies are grounded in the reported evidence.

While interpreting evidence from individual research reports, systematic reviewers should be cognisant of the quality criteria that are commensurate with the epistemological positioning of the original study. It is important to ethically reflect on plausible reasons for critical information that may be missing from individual reports and how might that influence the report findings (Dunkin 1996 ). Through purposefully informed selective inclusivity, systematic reviewers must distil information that is most relevant for addressing the synthesis purpose.

Often a two-stage approach is appropriate for evaluating, interpreting and distilling evidence from individual studies. For example, in their review that won the American Educational Research Association’s Review of the Year Award , Wideen et al. ( 1998 ) first evaluated individual studies using the criteria aligned with the methodological orientation of individual studies. Then, they distilled information that was most relevant for addressing their review purpose. In this phase, systematic reviewers must ethically pay particular attention to the quality criteria that are aligned with the overarching methodological orientation of their review, including some of the following criteria: reducing any potential biases, honouring representations of the participants of primary research studies, enriching praxis of participant reviewers or constructing a critically reflexive account of how certain discourses of an educational phenomenon have become more powerful than others. The overarching orientation and purpose of the systematic review should influence the extent to which evidence from individual primary research studies is drawn upon in a systematic review to shape the review findings (Major and Savin-Baden 2010 ; Suri 2018 ).

5 Constructing Connected Understandings

What are key ethical considerations associated with constructing connected understandings in a systematic review?

Through informed subjectivity and reflexivity, systematic reviewers must ethically consider how their own contextual positioning is influencing the connected understandings they are constructing from the distilled evidence. A variety of systematic techniques can be used to minimise unacknowledged biases, such as content analysis, statistical techniques, historical methods, visual displays, narrative methods, critical sensibilities and computer-based techniques. Common strategies for enhancing quality of all systematic reviews include ‘reflexivity; collaborative sense-making; eliciting feedback from key stakeholders; identifying disconfirming cases and exploring rival connections; sensitivity analyses and using multiple lenses’ (Suri 2014 , p. 144).

In addition, systematic reviewers must pay specific attention to ethical considerations particularly relevant to their review’s epistemological orientation. For instance, all post-positivist systematic reviewers should be wary of the following types of common errors: unexplained selectivity, not discriminating between evidence of varying quality, inaccurate coding of contextual factors, overstating claims made in the review beyond what can be justified by the evidence reported in primary studies and not paying adequate attention to the findings that are at odds with the generalisations made in the review (Dunkin 1996 ). Interpretive systematic reviews should focus on ensuring authentic representation of the viewpoints of the participants of the original studies as expressed through the interpretive lens of the authors of those studies. Rather than aiming for generalisability of the findings, they should aim at transferability by focusing on how the findings of individual studies intersect with their methodological and contextual configurations. Ethical considerations in participatory systematic reviews should pay attention to the extent to which practitioner co-reviewers feel empowered to drive the agenda of the review to address their own questions, change their own practices through the learning afforded by participating in the experience of the synthesis and have practitioner voices heard through the review (Suri 2014 ). Critically oriented systematic reviews should highlight how certain representations silence or privilege some discourses over the others and how they intersect with the interests of various stakeholder groups (Baker 1999 ; Lather 1999 ; Livingston 1999 ).

6 Communicating with an Audience

What are key ethical considerations associated with communicating findings of a systematic review to diverse audiences?

All educational researchers are expected to adhere to the highest standards of quality and rigour (AERA 2011 ; BERA 2018 ). The PRISMA-P group have identified a list of ‘Preferred reporting items for systematic review and meta-analysis protocols’ (Moher et al. 2015 ) which are useful guidelines to improve the transparency of the process in systematic reviews. Like all educational researchers, systematic reviewers also have an obligation to disclose any sources of funding and potential conflicts of interest that could have influenced their findings.

All researchers should reflexively engage with issues that may impact on individuals participating in the research as well as the wider groups whose interests are intended to be addressed through their research (Greenwood 2016 ; Pullman and Wang 2001 ; Tolich and Fitzgerald 2006 ). Systematic reviewers should also critically consider the potential impact of the review findings on the participants of original studies and the wider groups whose practices or experiences are likely to be impacted by the review findings. They should carefully articulate the domain of applicability of a review to deter the extrapolation of the review findings beyond their intended use. Contextual configurations of typical primary research studies included in the review must be comprehensively and succinctly described in a way that contextual configurations missing from their sample of studies become visible.

Like primary researchers, systematic reviewers should reflexively engage with a variety of ethical issues associated that potential conflicts of interest and issues of voice and representation. Systematic reviews are frequently read and cited in documents that influence educational policy and practice. Hence, ethical issues associated with what and how systematic reviews are produced and used have serious implications. Systematic reviewers must pay careful attention to how perspectives of authors and research participants of original studies are represented in a way that makes the missing perspectives visible. Domain of applicability of systematic reviews should be scrutinised to deter unintended extrapolation of review findings to contexts where they are not applicable. This necessitates that they systematically reflect upon how various publication biases and search biases may influence the synthesis findings. Throughout the review process, they must remain reflexive about how their own subjective positioning is influencing, and being influenced, by the review findings. Purposefully informed selective inclusivity should guide critical decisions in the review process. In communicating the insights gained through the review, they must ensure audience-appropriate transparency to maximise an ethical impact of the review findings.

For research involving patients, whether directly or indirectly, or involving NHS facilities, the ethical review process is mandatory. Justin Nowell takes you through it

Why read about ethics?

During their career journey many health professionals do a formal period of research. You may wish to improve your personal portfolio or raise the profile of a new department. Or are you thinking about pursuing research in the NHS? If so, you need to think carefully about ethics. As a chief investigator, whether you are a general practitioner or a nurse, a physiotherapist or a professor of medicine, the process is identical. It would be wise to plan your ethics application early, well before your proposed start date. The requirement for ethical approval applies not only to interventions like clinical trials but also to a range of other activities such as questionnaires, case note reviews, telephone surveys, and collecting samples or data. Many people find the process of applying for NHS ethical approval intimidating. A galaxy of red tape is guaranteed to dampen enthusiasm even in the most ardent researchers, however brilliant their ideas. Some knowledge of the application and review process can help ease this burden. Advance preparation may also save you a lot of wasted time.

Do I need ethical approval?

Traditionally, medical students are taught that the cornerstones of good ethics comprise beneficence, non-maleficence, autonomy, justice, dignity, and truthfulness. Therefore activities that damage these six principles undermine ethics. It is not always clear how to translate such lofty ideals into improving research. The General Medical Council advises that research involving people directly or indirectly is vital in improving care and reducing uncertainty for patients now and in the future, and for improving the health of the population as a whole. GMC guidance 1 requires that if you are involved in designing, organising, or doing research you must:

Put the protection of the participants’ interests first

Act with honesty and integrity

Follow the appropriate national research governance guidelines and the guidance in Research: The role and responsibilities of doctors . 2

Ethical review from the appropriate NHS research ethics committee is required for any research involving:

Patients and users of the NHS. This includes all potential research participants recruited by virtue of the patient’s or user’s past or present treatment by, or use of, the NHS. It includes NHS patients treated under contracts with private sector institutions

Individuals identified as potential research participants because of their status as relatives or carers of patients and users of the NHS, as defined above

Access to data, organs, or other bodily material of past and present NHS patients

Fetal material and in vitro fertilisation involving NHS patients

Those who have died recently in NHS premises

The use of, or potential access to, NHS premises or facilities

NHS staff recruited as research participants by virtue of their professional role

Healthy volunteers, if done on NHS premises.

Application form

Obtaining ethical approval is divided into national and local stages. The first task is to complete an application form. This has recently changed from the National Research Ethics Service form to a new Integrated Research Application System. 3 This is much more than just a form; it is an integrated dataset designed to fulfil the requirements of a number of review bodies. Detailed guidance notes are included in the form, but completion is time consuming, so save completed sections as you go and return later.

The aim of the ethics review process is to protect participants and promote good quality research. With this in mind, there are some searching questions to answer. There are four parts A-D and some additional forms. Part A comprises the generic and core information. Answers to part A automatically generate appropriate header sections and datasets for the remainder of the application. Part A has 78 questions, although not all questions will need to be answered and the form sieve will automatically reflect this. Resist the temptation to cut and paste large sections of your protocol—it will be obvious at the review meeting if you do. You are asked to write a comprehensive lay summary and it is worth paying special attention to this task. Since 1 May 2008 lay summaries have been published, and this will soon be extended to include summary ethical opinions. 4

Part B, comprising 25 questions, asks specifically about the product or device to be tested, tissue collection, and information security measures. Part C contains an overview of all research sites. Part D is the declarations section. There are also Research Tissue Bank and Medicines and Healthcare products Regulatory Agency forms to complete if relevant.

Applicant’s checklist

After completing the application form you must complete an applicant’s checklist. The checklist specifies supporting documents to be attached, including patient information sheets, consent forms, sometimes a letter from a statistician, and investigator and subinvestigator CVs. Online guidance is available on the format of protocols and other documents, but if you are unsure ask someone experienced; patient advisory groups are helpful in drafting documents designed to inform patients.

There is no prohibition on asking individual members of your local research ethics committee for advice; several of them are likely to be local health professionals. Probably the most valuable advice is to remember to identify all documents with a date and version number.

Where to apply

If you are unsure, the National Research Ethics Service website 4 contains a list of all local research ethics office contacts, which will be able to advise where to submit and how to book a review slot. Usually this will be via your local research ethics committee. The website also contains the standard operating procedures for ethics committees.

Provided the applicant’s checklist is complete, a reference number is issued, and the forms are locked, printed, and signed. If you do make a mistake you can ring the National Research Ethics Service helpline and they can unlock the form. Deliver signed hard copy forms with supporting documents to the designated research ethics committee office. Local research ethics committees consider around five to 10 studies a month. If they are fully booked you may be asked to return for submission the following month. There is no waiting list system for the research ethics committee —it is first come, first served. If time is tight, you could opt at this stage to submit to another research ethics committee within the same domain (area served by the same strategic health authority). Check local arrangements for submission carefully, because procedures may vary slightly. In some NHS trusts the research and development department wants to scrutinise the application before submission.

Once the application form and checklist have been approved you will receive a letter from the research ethics committee stating that the application is validated and giving a date for review. Ethics committees must provide an opinion within 60 days of validating an application.

Site specific information

The final online forms are the site specific information forms, which are submitted once the application is validated. The form has two purposes: one is to obtain NHS permission (a universal requirement) and the other is to request site specific assessment. Some types of study, such as questionnaires and surveys, are designated site specific assessment exempt. For most studies, however, once ethical approval is obtained local site specific assessment approval is required using the form. This is designed to ensure that individual sites have appropriate local resources to support the study safely.

The committee has a maximum of 18 members and one third of these are lay members. The investigator will receive an invitation to the meeting, and although attendance is not compulsory, it is advisable. The committee will consider the application for up to half an hour and then call in the investigator to answer questions. If you do attend, it will expedite the process as you may be able to clarify points raised by individual research ethics committee members.

Notification of decision

After the review meeting you will be informed of the committee’s provisional opinion, subject to certain conditions or any further information that is required. If the committee has serious concerns, complete resubmission may be requested. The committee will confirm their decision in writing within 10 days.

Request for further information

The committee may request further information or revision of documents before granting a final favourable ethical opinion. You will also be reminded that further consents may be required (site specific approval for other sites, research and development, Medicines and Healthcare products Regulatory Agency) before the study can begin.

Final approval and beyond

The research ethics committee will confirm the final ethical opinion in writing. Subsequent amendments to the study protocol must be formally notified to the committee. You are obliged to start your research within 12 months of a favourable ethical review. You must provide safety and progress reports as specified. You should also notify the committee when your study ends.

Since its introduction by the Nuremberg Code and the Declaration of Helsinki, the place held by ethics in biomedical research has been continuously increasing in importance. The past 30 years have also seen exponential growth in the number of biomedical articles published. A systematic review of the literature is the scientific way of synthesising a plethora of information, by exhaustively searching out and objectively analysing the studies dealing with a given issue. However, the question of ethics in systematic reviews is rarely touched upon. This could lead to some drawbacks, as systematic reviews may contain studies with ethical insufficiencies, may be a possible way to publish unethical research and may also be prone to conflict of interest. Finally, informed consent given for an original study is not necessarily still valid at the systematic review level. There is no doubt that routine ethical assessment in systematic reviews would help to improve the ethical and methodological quality of studies in general. However, ethical issues change so much with time and location, and are so broad in scope and in context that it appears illusory to search for a universal, internationally accepted standard for ethical assessment in systematic reviews. Some simple suggestions could nevertheless be drawn from the present reflection and are discussed in the paper.

Short abstract

Routine assessment may improve ethical standards and overall quality of trials

Our awareness of the requirements for ethical clinical research has increased over the past century. Research ethics committees were set up after the Declaration of Helsinki to review research proposals. Many journals now require a statement that ethical approval has been obtained before they consider a research report for publication. Nevertheless, many published studies do not come up to standard, or at least do not report that they do. For example, 30 out of 37 consecutive studies published in five general paediatric journals did not report whether informed consent was obtained. Twenty four of them did not report whether the committee on research ethics had approved the study. 1 We propose that systematic reviews of experimental clinical research on humans should also include information on the ethical standards of the trials.

Why include ethical information?

The main reason for including ethics in the checklist of systematic reviews is to increase awareness in the scientific community about the need for high ethical standards in research on humans. The proposal would also encourage reviewers to identify those occasional studies that were so unethical that there may be doubts about the morality of using the results. Although such trials are rare, history has given us too many real examples to allow us to be complacent. 2 , 3 Opinions differ on whether it is justified to disseminate the results of such studies. 4 Either way, a conscious decision should be made and revealed to readers of the review.

Issues around ethical quality overlap importantly with the central issues of the validity, reliability, and generalisability of research findings. They relate to some of the more subtle potential sources of bias in experimental clinical research. It is thus important to include ethical assessment in systematic reviews on prudential grounds as well as on moral grounds. The results of ethically sound trials may be more reliable than those from other trials. In a review of 767 randomised controlled trials published during 1993-5 in the New England Journal of Medicine, Lancet, BMJ , and JAMA , trials of higher methodological quality were more likely to provide information about their ethical aspects; so it seems that more reliable research is also more sensitive to the ethical requirements of research. 5

Which issues should we assess?

Ethical issues at the level of a systematic review are different from those for original research, and it might be unfair to examine all trials under the same ethical loupe. Older trials will have been done when ethical standards of research had not been as clearly formulated as they are today. Ethical standards depend not only on the time the study was performed but also on place and social mores.

Nevertheless, we think that examination of the ethical standards of trials should form part of every review, but the ethical principles to be applied need to be defined. Among the approaches to research ethics, we find that proposed by Foster most attractive. She suggests examining the project from three perspectives: goals, duties, and rights. 6 We used this model to devise a protocol to help assess the ethical quality of clinical trials included in systematic reviews (box).

Should systematic reviews merely delineate the ethical quality or attempt to integrate the observations into its conclusions? We believe that reviews should at least include a report of the ethical assessment and that the implications for further research should address the ethical gaps observed in existing studies.

How would the protocol work in practice?

We applied our protocol to a recently published systematic review of trials comparing β lactam monotherapy versus β lactam combined with aminoglycoside for febrile neutropenia. 9 The review included 47 studies carried out during 1981-2000 and 7807 randomised patients.

Goal related considerations

Financial support —Twenty eight trials gave information on financial support: all had received funding from the company that manufactured the monotherapy antibiotic. Three trials declared research grant support as well as commercial support.

Conflicts of interest —None of the studies included a statement related to potential conflicts of interest.

Justification —Thirty seven studies did not report a sample size calculation. We calculated that an equivalence trial design with an overall success rate of 60% (as observed in this review), and permitting a 20% difference between the treatments, would require around 200 assessable patients to ensure an 80% chance of rejecting at α = 0.05 the null hypothesis of equivalence. 10 Thirty eight trials had fewer than 200 patients. This requirement is modest given the broad difference permitted between the treatments. Compilation of all existing data in this review led us to believe that further trials comparing β lactam monotherapy with a narrower spectrum β lactam combined with an aminoglycoside would be unjustified. However, we could not identify a specific time at which this conclusion should have been reached.

Guide for ethical assessment of trials in systematic reviews

  • Is there a clear declaration on financial support in all trials?
  • Is there a statement that relates to potential conflicts of interest in all trials?
  • Justification—Could the results have been obtained by laboratory or animal experiments? Were any of the trials superfluous? Was the size of the study sufficient to achieve adequate statistical power?
  • Publication bias—How many of the identified trials remained unpublished? Is bias detectable by funnel plot analysis?

Duty related considerations

• Were the comparators appropriate? If a placebo was used, was it justified?

Rights related considerations

  • Safety—Was the risk for participants appropriate to the importance of the research? 7 Was appropriate follow up care assured?
  • Was informed consent obtained?
  • When participants had reduced competence, were appropriate measures taken to protect their best interests? 8
  • Were adequate steps taken to prevent unauthorised access to personal and clinical data?

Global considerations

• Was the study approved by a research ethics committee?

Publication bias —Five trials completed before 1990 (943 patients) remained unpublished or were published only as conference proceedings. The results of one study including 460 patients were never formally published. 11 Although we included these studies in our review, the funnel plot showed that small studies favouring combination therapy might be missing.

Appropriate comparators —We considered antibiotic combinations advised by guidelines contemporary to the study years as adequate. 12 - 14 Twenty trials used an inadequate comparator on this basis.

Safety —We considered monitoring aminoglycoside serum concentrations at any time during the study and creatinine at least twice weekly as minimal follow up measures to ensure patients' safety. Thirty one trials did not report aminoglycoside monitoring and 17 had inadequate creatinine follow up.

Informed consent —Twenty nine trials reported that informed consent had been obtained from adult patients.

Participants of reduced competence —Twenty five trials included patients younger than 16 years old, and in only five of these was consent obtained from parents or relatives. The trials covered a variety of patient populations, including some seriously ill patients with disseminated carcinoma and geriatric patients. Consent was sometimes given by the family rather than the patient, and in those cases it was not clear whether the family had any power of attorney to act on the patient's behalf.

Confidentiality —There was no information on steps taken to ensure confidentiality in the published reports.

Approval by research ethics committee —Twenty two studies stated that they had been approved by a research ethics committee. We noted an association between this approval and other ethical measures. All published studies with an adequate sample size reported approval, and an appropriate comparator was more commonly used in these studies than in studies that did not refer to the ethics committee (12/22 v 7/25 studies respectively).

Conclusions

Our proposed protocol showed several important ethical flaws in the studies on which we base our current management for cancer patients with febrile neutropenia. For most measures, the protocol enabled straightforward and systematic extraction of data on ethical issues. The details of how to assess several of the measures, such as the justification of studies or the appropriateness of the comparators, may need further consideration to allow for uniform evaluation in systematic reviews of different sorts.

Summary points

Many clinical trials do not report details of ethical issues

Including ethical assessment in systematic reviews will encourage researchers to conduct ethical research

Ethical research may provide more reliable results

Ethics can be assessed systematically by using the suggested protocol

We believe that including ethical considerations in systematic reviews will increase research workers' awareness of the need to conduct ethical research. It might also contribute to the interpretation of results. To encourage implementation of this proposal, we recommend that the next CONSORT statement should include ethical justification as an integral part of their protocol for reporting trials. 15
