Ethics in Biostatistics

Ethics in Biostatistics

• Biostatistics are crucial for ensuring scientific progress and public trust.
• Ethical biostatistics use data responsibly
• Core responsibilities involve data accuracy, confidentiality, and unbiased reporting
• Follow ethics throughout the research process

Introduction to Biostatistics Ethics

• Maintaining public trust and ensuring valid research conclusions are paramount.
• Researcher's obligations include participant rights.

Ethical Principles

• Respect for Persons: Informed consent is essential.
• Beneficence: Maximize benefits and minimize harm.
• Justice: Fair participant selection and equitable distribution of benefits.
• Integrity and Transparency: Honest reporting and accountability.

Importance of Biostatistical Ethics

• Preventing data misuse, such as fabrication or manipulation, is critical.
• Upholding ethical practices maintains scientific credibility.
• Protecting participant confidentiality and securing informed consent are paramount.

Ethical Approval

• All human subject research must receive approval from an Institutional Review Board (IRB) or ethics committee.
• Ethical review ensures study designs minimize risks and protect participants.

Informed Consent

• Provide participants with comprehensive details about study purpose, risks, and rights.
• Ensure consent is voluntary, documented, and comprehensible.
• Ethical oversight must remain constant throughout research.

Data Collection Ethics

• Obtain ethical approval from Institutional Review Boards (IRBs).
• Use informed consent for participant inclusion.
• Avoid undue influence or pressure during recruitment.

Data Management Ethics

• Securely store data using encrypted and safe systems.
• Restrict access to sensitive data.
• De-identify personal information (e.g., patient names).

Statistical Analysis Ethics

• Use appropriate statistical tools and methods.
• Avoid "p-hacking" (manipulating p-values to achieve desired outcomes).
• Report assumptions and limitations of the methodology used.

Responsible Data Sharing

• Share data transparently and with reproducibility in mind.
• Adhere to data privacy laws.
• Provide detailed metadata to aid future analysis.

Common Ethical Violations in Biostatistics

• Fabrication and Falsification: Inventing or altering data.
• Selective Reporting: Publishing only favorable results.
• Misleading Visualizations: Exaggerating data effects in visualizations).
• Ignoring Conflicts of Interest: Concealing financial or personal biases.

Ethical Guidelines in Biostatistics

• Declaration of Helsinki: Ethical principles for human research
• Belmont Report: Foundation for research ethics in the United States.
• American Statistical Association (ASA) Guidelines: Standards for professional statisticians.

Challenges in Maintaining Ethical Standards

• Pressure to Publish: Compromises ethical practices to meet publishing deadlines.
• Data Misinterpretation: Lack of statistical expertise among collaborators can lead to erroneous conclusions.
• Emerging Issues: Ethical concerns and guidelines related to the use of artificial intelligence (AI) and big data.

Example Scenario

• A pharmacy researcher evaluates a new antihypertensive drug, comparing it to a standard medication over six months. Funding comes from drug manufacturer.

Example: Ethical Violations and Consequences

• Data Exclusion: Excluding patients with significant side effects, falsely claiming they are outliers.
• Selective Reporting: Publishing only positive results related to a subgroup while ignoring negative results from other patients.
• Data Falsification: Altering data to more clearly show successful results.
• Impact on Literature: Misleading information affects healthcare providers' and policymakers' perceptions, which can adversely affect patients.
• Consequences: Harm to patients who rely on inaccurate study data, damage to the research field, and the potential for legal repercussions.

Conclusion

• Ethical biostatistics promotes scientific progress and public trust.
• Key responsibilities: ensuring data accuracy, maintaining confidentiality, and unbiased reporting.
• Ethics are crucial throughout all phases of research.
