The Role of the Research Ethics Committee: What Researchers Need to Know
A research ethics committee (REC), also known as an institutional review board (IRB) in the United States, is an independent body that assesses whether research involving human participants is ethically acceptable before the study begins. The fundamental role of the committee is the protection of the dignity and rights of research participants. Researchers need to understand that REC approval is not a bureaucratic hurdle but a substantive review of study design, risk-benefit balance, informed consent procedures, and data governance. This article explains what RECs do, how the review process works, what criteria committees apply, and how researchers can prepare applications that move through review efficiently and ethically.
At a Glance: What Research Ethics Committees Do
| Function | What It Means for Researchers | Common Outcome |
|---|---|---|
| Independent ethical review | Committee members who are not part of the research team assess the study protocol for ethical acceptability | Approval, required modifications, or rejection |
| Risk-benefit assessment | The committee weighs potential harms to participants against anticipated benefits to participants and society | Studies with poor risk-benefit balance are not approved |
| Informed consent oversight | The committee reviews consent documents and procedures to ensure participants can make voluntary, informed decisions | Consent forms are frequently returned for revision |
| Data and privacy governance | The committee evaluates how personal data will be collected, stored, shared, and protected | Additional data protection measures may be required |
| Ongoing monitoring | The committee reviews amendments, annual reports, and adverse events after initial approval | Studies may be suspended if problems emerge |
The Historical and Ethical Foundation of RECs
Research ethics committees were created about 50 years ago to independently assess the ethical acceptability of research projects involving human subjects. Their creation followed well-documented cases of research abuse where participants were harmed because no independent body reviewed the studies. The core principle that emerged is that researchers cannot be the sole judges of whether their own studies are ethical, because they have a vested interest in the research succeeding.
The role of the REC is best understood as an expert body making judgments about the acceptability of research proposals through a consensual weighing of different moral considerations. This model rejects the idea that committees are wrongfully paternalistic when they evaluate risks and benefits. Some scholars have argued that competent potential research subjects should make their own judgments about the acceptability of harms and benefits, and that this is not a legitimate role for any REC. However, the prevailing view is that committees serve a necessary protective function, particularly for participants who may not fully understand the research context or who may be vulnerable to pressure or inducement.
The ethical framework for REC review rests on several pillars. First, research should have social or scientific value. Second, the research design should be methodologically sound, because a poorly designed study cannot produce valid knowledge and therefore exposes participants to risk without generating benefit. Third, risks should be minimized and reasonable in relation to anticipated benefits. Fourth, informed consent should be obtained from participants in a manner that respects their autonomy. Fifth, vulnerable populations should receive additional protections. Sixth, privacy and confidentiality should be safeguarded.
The Composition of Research Ethics Committees
Research ethics committees are composed of members with diverse backgrounds and expertise. A typical committee includes medical scientists, clinicians, legal experts, laypersons, and sometimes nursing members. This diversity is intentional. Each member brings a different perspective to the review process, and the committee as a whole is better able to identify ethical issues than any single reviewer could.
Nursing members make an important and independent contribution to ethics committees in deliberations and decision-making regarding research ethics. Their role includes sharing perspectives and experiences in nursing, protecting research participants, evaluating the research design, representing the voice of research participants, confirming the informed consent documents, and ascertaining research participants' free will. Studies in Japan have shown that there is a slight difference between what other committee members expect of the role of nursing members and nursing members' recognition of their own role. This finding underscores the importance of member selection and training in ensuring that all committee members can contribute effectively.
Lay members serve a distinct function. They represent the perspective of the general public and help ensure that the committee does not become overly technical or detached from the concerns of ordinary people. Legal experts help the committee navigate regulatory requirements and identify legal risks. Clinicians contribute practical knowledge about medical care and patient populations. Scientists evaluate the methodological soundness of proposed research.
The diversity of committee membership also creates challenges. Studies of research ethics committee members in India found significant variability in awareness and understanding of genetic samples and their data reuse. Clinicians and medical scientists exhibited the highest levels of knowledge about genetic data for re-use, while laypersons and legal experts reported lower levels. This variability suggests that committees may need specialized training when reviewing complex research areas such as genetics, big data, or artificial intelligence.
The Review Process: From Submission to Decision
The REC review process follows a structured path from initial submission to final decision. Understanding this process helps researchers plan their timelines and prepare complete applications.
Submission and Administrative Screening
The process begins when the researcher submits a protocol package to the REC office. The package typically includes the study protocol, informed consent forms, recruitment materials, data collection instruments, and any relevant regulatory documents. The REC office conducts an administrative screening to ensure that all required documents are present and that the submission is complete.
Incomplete submissions are a common cause of delay. Researchers should check the REC website or contact the office to confirm the required document list before submitting. Many committees provide submission checklists that specify exactly what must be included.
Assignment to Reviewers
Once the submission passes administrative screening, the REC chair or coordinator assigns the protocol to one or more primary reviewers. The assignment considers the expertise of committee members relative to the study topic. A study involving genetic research would be assigned to reviewers with relevant scientific background, while a study involving vulnerable populations might be assigned to reviewers with experience in that area.
Primary reviewers conduct a detailed review of the protocol and prepare written comments. These comments are shared with the full committee before the meeting. The quality of the primary review often determines the quality of the full committee discussion.
Full Committee Meeting
The full committee meets to discuss the protocol. The primary reviewers present their assessments, and other members contribute their perspectives. The discussion covers the scientific merit of the study, the risk-benefit balance, the adequacy of informed consent procedures, the protection of vulnerable participants, and the data management plan.
Committee meetings can be conducted in person or online. During the COVID-19 pandemic, 92 percent of research ethics committees in one Indian study conducted online meetings. This shift demonstrated that remote review is feasible and may become a permanent feature of REC operations.
Decision Categories
After discussion, the committee makes one of several decisions. The study may be approved without changes, approved with minor modifications, or rejected. In many cases, the committee requests modifications and requires the researcher to resubmit the revised protocol for further review. The committee may also determine that the study is exempt from full review or eligible for expedited review.
The decision is communicated to the researcher in writing, along with the reasons for the decision and any required modifications. Researchers should read this communication carefully and respond to each point raised by the committee.
Review Timelines
Review timelines vary considerably across institutions and countries. A study of primary health care research protocols in Catalonia found that the mean time to protocol approval was 42.09 days, with a decrease of 20.1 days from 2019 to 2021. More than half of the approved protocols were approved within the first month after their initial evaluation.
A study of the National Dental PBRN Central Institutional Review Board found that the mean time from initial submission to approval was 55.2 days for studies requiring expedited or full review. Notably, 35 percent of this time was due to waiting on study investigator responses. This finding highlights the importance of responding promptly to committee requests for additional information.
Researchers should plan for review timelines of at least one to two months for full review studies. Studies involving complex ethical issues, vulnerable populations, or novel technologies may take longer. The review process for the same study protocol can vary dramatically across different local settings. One study of remote monitoring technologies in Alzheimer's disease research found that review processes differed across sites, with process duration varying from 71 to 423 days. Some RECs did not raise any issues, whereas others raised up to 35 concerns.
Criteria for Ethical Approval
Research ethics committees apply a consistent set of criteria when evaluating research protocols. Understanding these criteria helps researchers design studies that are more likely to receive approval.
Scientific Validity
The committee evaluates whether the study design is methodologically sound and capable of answering the research question. A study that cannot produce valid results exposes participants to risk without generating knowledge, which is ethically problematic. The committee considers the study design, sample size, statistical analysis plan, and outcome measures.
Researchers should ensure that their study design is appropriate for the research question and that the sample size is adequate to detect meaningful effects. The Experimental Design Assistant from the NC3Rs provides guidance on experimental design for animal studies, and similar principles apply to human research. The EQUATOR Network provides reporting guidelines for health research that can help researchers design studies that meet methodological standards.
Risk-Benefit Assessment
The relationship between risks and benefits is central to the ethics of research involving human participants. To be ethically justifiable, risks should be reasonable in relation to anticipated benefits to subjects and to the potential social benefits resulting from research.
The committee assesses both the probability and magnitude of potential harms. Harms can be physical, psychological, social, or economic. The committee also considers the potential benefits, which may accrue to the individual participant or to society more broadly.
Research participants frequently describe various types of inclusion benefits as important to them. These include personal benefits such as access to or improved health care, increased knowledge about their disease or condition, and greater solidarity with the local community. Unless participants are clearly mistaken in their perceptions, ethics committees should take these types of inclusion benefits into account in their risk-benefit assessment.
Informed Consent
The committee reviews the informed consent process to ensure that participants can make voluntary, informed decisions about participation. The consent form should describe the purpose of the study, the procedures involved, the risks and benefits, alternatives to participation, and the right to withdraw at any time without penalty.
The consent process is particularly challenging in certain research contexts. Research in emergency departments and critical care units presents unique obstacles because patients or their surrogates may be unable to provide informed consent within limited therapeutic windows. Accepted alternatives to informed consent include proxy consent, deferred consent, exceptions from consent, and waivers of consent. These alternatives are ethically and socially acceptable and compliant with regulations, but they are underutilized or may be abused.
The committee also evaluates whether the consent process is free from undue influence or coercion. Financial inducements to recruit research subjects are a particular concern. The committee has the power to prohibit the use of financial inducements that are excessive or that may compromise voluntary participation.
Protection of Vulnerable Populations
Certain populations require additional protections in research. These include children, pregnant women, prisoners, individuals with cognitive impairments, and economically or educationally disadvantaged persons. The committee evaluates whether the research design includes appropriate safeguards for these populations.
The committee also considers whether the research is responsive to the needs of the population being studied. Research involving vulnerable populations should generally offer the prospect of direct benefit to the participants or contribute to knowledge that will benefit the population.
Data Management and Privacy
The committee evaluates how personal data will be collected, stored, shared, and protected. This review has become increasingly important with the growth of big data, genetic research, and remote monitoring technologies.
Research ethics committees play an important role in reviewing data-intense research protocols. However, this regulatory role must be embedded in a context of robust governance. A survey of research ethics committee members in sub-Saharan Africa found that awareness of data governance laws, policies, and guidelines was variable across the subcontinent. A quarter of respondents indicated that national regulations on the trans-border flow of research data are inadequate. Most respondents believed that they lacked experience in reviewing data-intense protocols.
The reuse of genetic data raises significant ethical, legal, and social concerns. Research ethics committees serve as gatekeepers of responsible research in this area. They must balance the potential benefits of data reuse, which can accelerate scientific discovery and enhance the value derived from research investments, against the risks to research participants.
Benefit Sharing
In international collaborative research, particularly genomic and biobanking research, the question of benefit sharing is important. Researchers and research ethics committee members in Uganda identified several themes related to benefit sharing, including perceptions of the benefits of genomic and biobanking research, discussion of benefit sharing with participants during the informed consent process, legal implications of benefit sharing and the role of material transfer agreements, equity and fairness in sharing the benefits of genomic research, perceived barriers to fair benefit sharing, and recommendations for fostering fair and equitable benefit sharing.
Perceived barriers to fair benefit sharing include power disparities, weak research regulatory frameworks, and lack of scientific integrity. Researchers and committee members believed that the benefits of genomic and biobanking research should be fairly and equitably shared with low and middle-income country researchers and their institutions, and research communities.
Preparing an Ethics Application: A Step-by-Step Guide
Preparing a complete and well-organized ethics application is the most effective way to avoid delays and revisions. The following steps outline a practical approach to preparing an ethics application.
Step 1: Review the REC Requirements
Before preparing the application, review the REC website or contact the office to confirm the required document list, submission format, and review timelines. Different committees have different requirements, and what was acceptable at one institution may not be acceptable at another.
Step 2: Develop the Study Protocol
The study protocol is the central document in the ethics application. It should describe the research question, background and rationale, study design, participant population, recruitment procedures, study procedures, data collection methods, data analysis plan, and ethical considerations.
The protocol should be written clearly and completely. Committee members may not be experts in the specific research area, so the protocol should explain technical terms and justify methodological choices.
Step 3: Prepare the Informed Consent Documents
The informed consent form should be written in plain language that is understandable to the participant population. It should include all required elements, including the purpose of the study, procedures, risks, benefits, alternatives, confidentiality protections, and the right to withdraw.
The consent form should be reviewed by individuals who represent the participant population to ensure that it is understandable and culturally appropriate.
Step 4: Prepare Supporting Documents
Supporting documents may include recruitment materials, data collection instruments, questionnaires, interview guides, and any relevant regulatory approvals. These documents should be consistent with the study protocol and consent form.
Step 5: Complete the Application Form
The application form typically asks for information about the principal investigator, the research team, the study design, the participant population, the recruitment procedures, the consent process, the risk-benefit assessment, and the data management plan. The form should be completed carefully and completely.
Step 6: Submit the Application
Submit the application according to the REC requirements. Some committees require electronic submission, while others accept paper submissions. Confirm that all required documents are included and that the application is complete.
Step 7: Respond to Committee Requests
After the committee reviews the application, it may request modifications or additional information. Respond to each point raised by the committee in a timely and complete manner. The speed of the review process often depends on how quickly researchers respond to committee requests.
Required Documents Checklist
| Document | Purpose | Common Problems |
|---|---|---|
| Study protocol | Describes the research design and procedures | Incomplete methods, unclear research question |
| Informed consent form | Documents the consent process | Complex language, missing required elements |
| Recruitment materials | Describes how participants will be identified and invited | Misleading or coercive language |
| Data collection instruments | Includes questionnaires, interview guides, and other tools | Inconsistent with protocol, missing validation |
| Data management plan | Describes data collection, storage, sharing, and protection | Vague privacy protections, unclear retention periods |
| Investigator qualifications | Documents the research team's expertise | Missing CVs, inadequate training documentation |
| Regulatory approvals | Includes any required approvals from other bodies | Missing approvals, expired certifications |
Common Reasons for Rejection or Revision
Understanding the common reasons why ethics applications are rejected or sent back for revision helps researchers avoid these pitfalls.
Incomplete Submissions
Incomplete submissions are a common cause of delay. Missing documents, incomplete forms, and inconsistent information between documents can all trigger requests for additional information. Researchers should use the REC checklist to ensure that all required documents are included and complete.
Inadequate Risk-Benefit Analysis
Committees frequently identify problems with the risk-benefit analysis. Researchers may underestimate risks, fail to identify potential harms, or overstate potential benefits. The risk-benefit analysis should be honest and balanced, acknowledging uncertainties and limitations.
Problems with Informed Consent
Informed consent documents are a frequent source of committee concerns. Common problems include complex language that is difficult for participants to understand, missing required elements, and inadequate descriptions of risks. The consent form should be written in plain language and reviewed by representatives of the participant population.
Inadequate Protection of Vulnerable Populations
Research involving vulnerable populations requires additional safeguards. Committees may reject studies that do not include appropriate protections for children, pregnant women, prisoners, or individuals with cognitive impairments.
Poor Data Management Plans
Data management plans are increasingly important in ethics review. Committees may reject studies with vague privacy protections, unclear data retention periods, or inadequate security measures. The data management plan should describe how data will be collected, stored, shared, and protected throughout the research lifecycle.
Methodological Weaknesses
Committees evaluate the scientific validity of proposed research. Studies with weak designs, inadequate sample sizes, or unclear analysis plans may be rejected because they cannot produce valid knowledge.
Special Considerations for Different Research Types
Different types of research raise different ethical considerations. Researchers should be aware of the specific issues that apply to their research area.
Clinical Trials and Pharma-Sponsored Research
Participants of pharma-sponsored research are exposed to risks, benefits, and uncertainties that do not occur in other forms of clinical studies. Ethics committees represent the subjects' first line of protection. This responsibility begins with the study review and ends after all study subjects finish the intervention.
Pharma-sponsored research is a crucial driver to develop and implement innovative approaches to improve the informed consent process and the execution of the studies. However, the commercial context of this research raises additional concerns about conflicts of interest, financial inducements, and the balance between commercial interests and participant protection.
Genetic and Biobanking Research
Genetic research and biobanking raise unique ethical considerations related to data sharing, benefit sharing, and the reuse of samples and data. Research ethics committees serve as gatekeepers of responsible research in this area.
The reuse of genetic data can accelerate scientific discovery, reduce redundancy, and enhance the value derived from research investments. However, the reuse of genetic data also raises significant ethical, legal, and social concerns. Committees must balance the benefits of data reuse against the risks to research participants.
Big Data Research
The governance of big data presents growing challenges for research ethics committees. Finding the right balance between making large volumes of data accessible and safeguarding privacy, preventing data misuse, determining authorship, and protecting intellectual property remains challenging.
Research ethics committees play an important role in reviewing data-intense research protocols. However, this regulatory role must be embedded in a context of robust governance. Many committee members report that they lack experience in reviewing data-intense protocols, suggesting a strong need for capacity development.
Artificial Intelligence Research
Oversight of artificial intelligence in human subjects research presents unique challenges. These challenges arise from both the non-linear and iterative nature of AI development, as well as from the way AI shifts risk from individual research subjects to larger populations affected by AI-driven decisions and data handling.
Traditional institutional review boards often struggle to keep pace with these changes, which can lead to gaps in risk assessment and delays in the review process. Risk-based oversight models that align ethical and regulatory review with an AI project's stage of maturity and potential human impact have been proposed to address these challenges.
Remote Monitoring Technologies
Clinical research with remote monitoring technologies has multiple advantages over standard paper-pencil tests, but also raises several ethical concerns. These include data management, participant wellbeing, methodological issues, and the issue of defining the regulatory category of the technologies.
A study of remote monitoring in Alzheimer's disease research found that review processes differed across sites, with some RECs not raising any issues and others raising up to 35 concerns. The approval of a data protection officer was needed in half of the sites. These differences suggest that multi-site studies would benefit from harmonization in research ethics governance processes.
Quality Improvement Projects
Quality improvement projects present a particular challenge for ethics review. In the past two decades, institutional review boards and practitioners have struggled with incorporating uniformity in the review of research versus quality improvement design. Despite the efforts of experts in ethics and calls to develop formal processes, consistency issues are still a challenge in traditional IRB review models.
The process to mandate the IRB as the sole decision-maker for quality improvement projects may lead to overregulation and bottlenecks in the institutional workflow. Institutions need to proactively establish when governance models are necessary for quality improvement projects and promote interaction and cooperation when addressing ethical and regulatory standards outside of the IRB to reduce overregulation.
The Changing Landscape of Ethics Review
The landscape of research ethics review is changing in response to new challenges and reforms.
Centralization of Review
Both in the United States and in the European Union, reforms that aim at the centralization of the review process were recently approved. The National Institutes of Health implemented a single IRB policy in 2018, and the European Union adopted Regulation (EU) No 536/2014 on clinical trials.
Centralized review models offer potential benefits, including reduced administrative burden and greater consistency across sites. However, they also raise concerns about the risk of narrowing the scope of the ethics review and disregarding the local context.
The National Dental PBRN Central Institutional Review Board provides an example of a centralized model. The CIRB reviews study protocols, documents, consent forms, and HIPAA forms. Once CIRB approval is obtained, the study packet is sent to local institutions for local context review. Local institutions may revise specific sections agreed on in reliance agreements but must make determinations regarding the HIPAA Privacy Rule.
The CIRB did not ensure a shorter approval time because local context review approvals must wait for initial CIRB approval. However, substantial benefits were realized later because subsequent amendments and annual reviews only required CIRB review, saving local institutions from involvement in these reviews.
The Impact of the COVID-19 Pandemic
The COVID-19 pandemic had a significant impact on research ethics committees. Research ethics committees played a crucial role in expediting the review of research protocols amidst the pandemic. The number of committee sessions increased during the pandemic, and many committees conducted online meetings.
A study of primary health care research protocols in Catalonia found that the number of sessions increased during the COVID-19 pandemic, from 12 in 2019 to 25 in 2020 and 18 in 2021. A total of 751 protocols were evaluated during the study period. The mean time to protocol approval was 42.09 days, with a decrease of 20.1 days from 2019 to 2021.
The most common challenges faced by committees during the pandemic included risk-benefit analysis, review of informed consent, and protocols involving vulnerable populations. Many committee members reported the need for ethics review training, and most agreed that committees require training in COVID-19 protocol review.
The pandemic paved the way for the transition towards the centralized model. An analysis of its impact on the research review process could provide insights into possible shortcomings of this new model.
Dual-Use Research
Dual-use research, which can be used for both beneficial and harmful purposes, presents particular challenges for ethics review. The World Health Organization Global Guidance Framework for the Responsible Use of the Life Sciences addresses the governance of biorisks, including dual-use research, for countries. It emphasizes engaging multisectoral stakeholders such as governments, scientific bodies, health and research institutes, standard-setting organizations, funding bodies, and others.
National ethics committees could make a valuable contribution by providing ethical guidance in the decision-making process for dual-use research. However, a landscape analysis found that national ethics committees have contributed to guiding policy and assessing dual-use research risks in only a limited number of countries. Recommendations include establishing a multistakeholder, coordinated oversight mechanism at the country level, strengthening international linkages, and involving ethics committees as an expert resource in the governance and oversight process.
Records and Measurements for Researchers
Researchers should maintain records of the ethics review process and measure key metrics to improve their applications over time.
Records to Maintain
Maintain a copy of the submitted application, all correspondence with the REC, the committee's decision letter, and any modifications made in response to committee requests. These records document the ethical review process and may be required for audits or future submissions.
Measurements to Track
Track the time from submission to decision, the number of committee requests for additional information, and the number of modifications required. These metrics can help researchers identify common problems in their applications and improve their preparation process.
Learning from Committee Feedback
Committee feedback is a valuable learning opportunity. Researchers should review committee comments carefully and incorporate the feedback into future applications. Common themes in committee feedback can reveal systemic issues in the research team's approach to ethics.
Common Failure Patterns in Ethics Applications
Several failure patterns recur across ethics applications. Recognizing these patterns helps researchers avoid them.
The Checklist Approach
Some researchers treat the ethics application as a paperwork exercise instead of a substantive ethical analysis. They complete the required forms without engaging deeply with the ethical issues raised by their research. This approach often results in applications that are technically complete but substantively inadequate.
The Defensive Approach
Some researchers write ethics applications defensively, minimizing risks and overstating benefits in an attempt to secure approval. This approach is counterproductive because committees are experienced at identifying unrealistic risk assessments. An honest and balanced risk-benefit analysis is more likely to be viewed favorably.
The One-Size-Fits-All Approach
Some researchers use a template consent form or protocol from a previous study without adapting it to the specific research context. This approach can result in consent forms that do not adequately describe the actual study procedures or risks.
The Last-Minute Approach
Some researchers prepare ethics applications at the last minute, leaving insufficient time for careful preparation and review. This approach often results in incomplete submissions and avoidable delays.
Limitations of Research Ethics Committees
Research ethics committees have limitations that researchers should understand.
Variability Across Committees
The review process can vary dramatically across different committees and settings. The same study protocol may receive different reviews from different committees. This variability can be frustrating for researchers conducting multi-site studies.
Limited Capacity for Specialized Review
Committee members may lack experience in reviewing certain types of research, such as data-intense protocols or artificial intelligence research. Many committee members report that they lack experience in reviewing data-intense protocols, suggesting a strong need for capacity development.
The Challenge of Balancing Speed and Thoroughness
Committees face pressure to review protocols quickly, particularly during public health emergencies. However, rapid review must not compromise the quality of ethical assessment. The COVID-19 pandemic demonstrated that committees can expedite review while maintaining quality, but this requires adequate resources and training.
The Risk of Overregulation
The process to mandate the IRB as the sole decision-maker for quality improvement projects may lead to overregulation and bottlenecks in the institutional workflow. Institutions need to develop appropriate governance structures that balance the need for ethical oversight with the need for efficiency.
Professional Escalation Criteria
Researchers should escalate concerns to the REC or appropriate authorities in certain situations.
Report Adverse Events
Adverse events that occur during the course of a study should be reported to the REC according to the committee's requirements. The committee will assess whether the adverse event changes the risk-benefit balance of the study and whether modifications are needed.
Report Protocol Deviations
Deviations from the approved protocol should be reported to the REC. The committee will assess whether the deviation affects participant safety or the scientific validity of the study.
Seek Guidance for Unclear Situations
If researchers are uncertain about whether a proposed activity requires ethics review, they should seek guidance from the REC. Many committees provide preliminary consultations that can help researchers determine the appropriate review pathway.
Escalate Concerns About Research Misconduct
If researchers become aware of research misconduct, including fabrication, falsification, or plagiarism, they should report their concerns to the appropriate institutional authorities.
Frequently Asked Questions
What is the difference between a research ethics committee and an institutional review board?
A research ethics committee and an institutional review board are the same type of body with different names in different jurisdictions. The term institutional review board is commonly used in the United States, while research ethics committee is more common in other countries. Both terms refer to an independent body that assesses the ethical acceptability of research projects involving human subjects.
When does a research project require ethics committee approval?
Research projects involving human participants generally require ethics committee approval before the study begins. This includes research involving human subjects, human tissue, or identifiable personal data. Some activities, such as quality improvement projects, may not require full ethics review, but researchers should seek guidance from their local committee to determine the appropriate review pathway.
How long does ethics review take?
Review timelines vary considerably across institutions and countries. Studies have found mean times to approval ranging from about 42 days to about 55 days for studies requiring full or expedited review. The review process can take longer for studies involving complex ethical issues, vulnerable populations, or novel technologies. Researchers should plan for review timelines of at least one to two months.
What should I do if my ethics application is rejected?
If your ethics application is rejected, review the committee's decision letter carefully to understand the reasons for the rejection. Address each concern raised by the committee and resubmit the revised application. Many committees are willing to work with researchers to improve their applications.
Can I start my research before receiving ethics approval?
No. Research involving human participants should not begin before receiving ethics committee approval. Starting research before approval is a serious ethical violation that can result in the suspension of the study and disciplinary action.
What is the role of the lay member on a research ethics committee?
Lay members represent the perspective of the general public on the research ethics committee. They help ensure that the committee does not become overly technical or detached from the concerns of ordinary people. Lay members contribute to discussions about informed consent, risk communication, and the acceptability of research procedures from a non-specialist perspective.
How should I respond to committee requests for modifications?
Respond to each point raised by the committee in a timely and complete manner. Provide a point-by-point response that explains how you have addressed each concern. If you disagree with a committee request, explain your reasoning clearly and respectfully. The speed of the review process often depends on how quickly researchers respond to committee requests.
What training is available for researchers on research ethics?
Many institutions offer training on research ethics for researchers. Studies have found that researchers involved in more research projects have higher awareness of the ethics committee and its role. Continuous and customized training on research ethics is recommended for all researchers.
