Control resolutions ensure ethical values are applied in hospitals by considering ethics in accreditation processes. Guidelines like the Declaration of Helsinki provide authoritative guidance for human research ethics. Ethics committees review proposed research before it begins to safeguard participants and ensure research quality. Committees have 5-15 diverse members including medical scientists, clinicians, legal experts, and community members. They provide independent review of studies' ethics, design, consent processes, qualifications, infrastructure, risks and benefits, confidentiality, and post-trial access.
