Outline of Content

  1. Ethics in Research

  2. Different Types of Reviews

    • Torrens University Australia

Discussion of Ethics

  • Reflect on what the word ethics means to individuals.

Brief History of Ethics

1947: Nuremberg Code

  • Established by the World Medical Association.

  • A response to the unethical research from World War II.

  • Introduced basic principles for medical research conduct.

1964: Declaration of Helsinki

  • Further elaboration on the Nuremberg Code.

  • Defined ethical principles to guide research including:

    • Informed consent: Freedom to choose participation.

    • Scientific Excellence: Ensuring high-quality research.

    • Minimizing Harm: Reducing risks to participants.

    • Confidentiality: Protecting personal information.

    • Conflict of interest: Ensuring unbiased research.

Understanding Ethics

Definition (Polgar & Thomas, 2013)

  • Ethics: Moral principles guiding human behavior.

  • Community values determine what is right or wrong in research, with a focus on participant well-being.

Principles of Human Research Ethics

  • Research must:

    • Be worthwhile and beneficial to the community.

    • Uphold merit and integrity.

    • Respect human autonomy and freedom of choice.

    • Obligation to maximize benefit and minimize harm (Beneficence).

    • Ensure just allocation of research benefits and burdens (Justice).

Values and Principles of Ethical Conduct

  • Promote ethical human research.

  • Informed by the National Statement on Ethical Conduct in Human Research 2023 - NHMRC.

Ethical Considerations for Participants

  • Special ethical considerations for:

    • Pregnant individuals and fetuses.

    • Children and young people.

    • People in dependent/unequal relationships.

    • Individuals unable to consent (e.g., medical assistance).

    • Individuals with cognitive impairments or those involved in illegal activities.

    • Aboriginal and Torres Strait Islander peoples.

    • Participants in other countries.

Human Research Ethics Committee (HREC)

Considerations by HREC

  • Primary consideration is participant welfare.

  • Assessment of:

    • Potential for harm and risks.

    • Balance between benefits and risks.

    • Ethical recruitment process.

    • Sufficiency of information for informed consent.

    • Confidentiality measures.

    • Special provisions for vulnerable groups.

Types of Reviews in Research

Secondary Sources

  • General Literature Review: Comprehensive review of literature on specific topics for assignments.

    • Concise Literature Review: Short review in research paper introduction to contextualize research.

    • Primary Research: Original studies on a topic, providing first-hand data.

    • Secondary Research: Synthesizes information from primary research.

Knowledge Dissemination

  • Summarizing and contrasting previous research findings.

  • Identifying gaps in knowledge to guide future research.

  • Always critically assess primary sources of information.

Systematic Review vs. Literature Review

Systematic Review

  • Focused question, explicit methodology, systematic search criteria.

  • Clear inclusion/exclusion criteria and article selection process.

  • High-quality evidence synthesis.

Literature Review

  • May or may not focus on a single question, no predefined protocol.

  • Less structured, possibly influenced by reviewer's beliefs.

Key Aspects of Systematic Reviews & Meta-Analysis

  • Systematic Review Characteristics:

    • Clearly stated objectives and eligibility criteria for studies.

    • Explicit methodology and assessment of risk of bias.

  • Meta-Analysis:

    • Incorporates statistical combination of studies with related hypotheses.

    • Increases power and improves effect size estimates.

Advantages and Disadvantages of Systematic Review & Meta-Analysis

Advantages

  • Comprehensive overview of existing evidence.

  • Generalizable findings across populations.

  • Time efficient compared to new study creation.

Disadvantages

  • Difficulty in combining studies with different outcomes.

  • Extensive time investment in review process.

Steps for Undertaking a Systematic Review

  1. Study Objective: Define the purpose and key questions.

  2. Develop the Protocol: Specify study designs, participants, and outcome measures.

  3. Search Strategy: Identify databases and select keywords, include grey literature.

  4. Evaluate Methodological Quality: Use scales (Jadad, PEDro, QUADAS) for study quality assessment.

  5. Data Synthesis: Analyze similarities and differences in included studies.

  6. Discussion and Conclusions: Integrate findings and suggest future research directions.

Special Considerations in Study Quality

  • Ensure randomization and blinding to minimize bias.

  • Evaluate loss rates and outcomes across study groups carefully.

Final Reminders

  • Complete Test A and start on Assessment 2: Journal article summary.

Examples to Correct

  • Reference formatting and author citation guidelines shared from module activities.

  • Reminder about correct in-text citations.

Questions

  • Open floor for any questions, clarifications or further discussions.
