When can an individual's medical record information be released to research organizations?

The release of an individual's medical record information to research organizations is primarily determined by existing laws and regulations governing patient confidentiality and privacy. The correct answer underscores that any release must not violate these laws, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States, which establishes strict guidelines for privacy and the sharing of Protected Health Information (PHI).

While obtaining consent from an individual is a common practice and can facilitate information sharing (as mentioned in the first option), the overall legal framework takes precedence. Situations arise where data might be shared for research purposes, but only if done in adherence to legal requirements, ensuring that individuals' rights and confidentiality are respected.

The other options focus on logistical aspects or individual convenience rather than the legal compliance necessary for releasing medical records. Thus, they do not capture the essential requirement that legal standards must always be maintained when sharing medical record information with research organizations.
