The Public Health Service (PHS) Responsibility of Applicants for Promoting Objectivity in Research for Which PHS Funding is Sought (42 CRF 50, Subpart F) regulation governs the identification and management of conflics of interest in research for investigators who receive or apply for funding from agencies of the PHS.


Who is Considered a PHS Investigator?

PHS defines an investigator as any individual, regardless of title or position, who is responsible for the design, conduct or reporting of research funded by the PHS or proposed for such funding.

At OSU, we include the following categories of individuals as investigators:

  1. Professorial faculty
  2. Research Associates
  3. Postdoctoral Fellows and Scholars
  4. Any individual listed by name on a PHS proposal, grant or subaward/contract
  5. Any individual responsible for the design, conduct or reporting of OSU research

Consultants as listed on sponsored projects and defined by the Office of Sponsored Research and Awards Administration (OSRAA) are not considered responsible for the design, conduct or reporting of research, but instead undertake specific tasks that are reviewed by OSU investigators who are designated as responsible for design, conduct and reporting of research.

What are the COI Requirements for PHS Investigators?

Disclose Significant Financial Interests

PHS requires the disclosure of significant financial interests held by PHS-funded investigators prior to submitting a PHS funding proposal and thereafter for the lifetime of the award on an annual basis or within 30 days of discovering or acquiring a new significant financial interest.

Significant financial interests include remuneration from and equity in publicly traded and non-publicly traded entities, as well as intellectual property rights and reimbursed or sponsored travel.

OSU facilitates the disclosure of significant financial interests of remuneration, equity interests and intellectual property through the online disclosure form.  All OSU investigators are required to complete this form, regardless of funding source.  The disclosure of reimbursed or sponsored travel only applies to PHS investigators and is disclosed separately.

PHS definition of significant financial interest:

Disclose Travel Reimbursements and Sponsorship

PHS requires the disclosure of reimbursed or sponsored travel for PHS-funded investigators within 30 days of the occurence of the travel.  The travel must be related to the investigator's institutional responsibilities and be reimbursed or sponsored by an entity other than a Federal, state or local government agency, an institution of higher education, an academic teaching hospital, a medical center, or a research institute that is affiliated with an insttution of higher education.

Important Note: If the travel is sponsored or reimbursed by an entity that receives money from a government agency or institution of higher education (or any of the excluded entities listed above), you must still disclose the travel if the funds came directly from the non-governmental or higher education entity (e.g., a workshop funded by a federal funding agency but organized by a professional society).

Complete COI Training on Regulations and Institutional Policy

PHS requires that PHS investigators be informed of OSU's policy on conflicts of interest, their disclosure requirements, and the PHS regulations governing conflicts of interest.  PHS also requires that this training be conducted every four years, when OSU's policy is revised, when an investigator is new to OSU, and if an investigator is found to be non-compliant with OSU policy or COI management.
