What NIH’s New Research-Misconduct Rule Changes
New allegations of research misconduct involving Public Health Service-supported biomedical or behavioral research now follow a revised federal framework, including work funded by the National Institutes of Health.
The important dividing line is January 1, 2026. The Department of Health and Human Services published the Office of Research Integrity’s final rule on September 17, 2024. The rule became effective January 1, 2025, but its regulatory requirements apply to allegations received by institutions on or after January 1, 2026.
Allegations received before January 1, 2026, generally remain subject to the 2005 version of 42 CFR Part 93. The institution and respondent may instead elect in writing to use the revised rule.
Who is covered
The framework applies to institutions that apply for or receive Public Health Service support for biomedical or behavioral research, related research training, or activities connected with that work. It covers allegations involving applications and proposals, supported research, research records, training programs and related activities.
That includes many NIH-supported projects, but it is not an NIH-only rule. The operative question is whether the research or related activity falls within the Public Health Service framework and its coverage requirements.
What counts as research misconduct
The rule is not a prohibition on flawed, controversial or unpopular science. It defines research misconduct as fabrication, falsification or plagiarism in proposing, performing or reviewing research, or in reporting research results.
Fabrication means making up data or results and recording or reporting them. Falsification involves manipulating research materials, equipment or processes, or changing or omitting data or results so the research is not accurately represented in the research record. Plagiarism is using another person’s ideas, processes, results or words without appropriate credit.
The rule excludes honest error and differences of opinion. A finding also requires three additional elements: a significant departure from accepted practices in the relevant research community, intentional, knowing or reckless conduct, and proof by a preponderance of the evidence.
How a case moves forward
Covered institutions must maintain written policies and procedures and respond in a thorough, competent, objective and fair manner. They must address conflicts of interest, protect relevant records and take reasonable and practical steps to protect good-faith complainants, witnesses and committee members from retaliation.
The first stage is an institutional assessment. The institution must document the assessment and retain enough information to explain why the matter was closed or advanced. If an inquiry is warranted, the institution must obtain or sequester the research records and other evidence needed for the proceeding.
An inquiry is a preliminary review of whether an allegation falls within the rule and may have substance. It generally must be completed within 90 days. If it takes longer, the inquiry report must explain why. The respondent must receive notice, a copy of the inquiry report and an opportunity to comment. A finding of misconduct cannot be made at the inquiry stage.
An investigation is warranted when there is a reasonable basis to conclude that the allegation involves covered PHS-supported research and that preliminary fact-finding indicates the allegation may have substance. The institution must notify ORI within 30 days of deciding that an investigation is warranted and provide the inquiry report and specified supporting information.
What institutions must document
During an investigation, institutions must obtain the research records and other evidence needed to reach a decision, examine relevant evidence, use people with appropriate scientific expertise and take reasonable steps to avoid unresolved conflicts of interest.
The institution must interview the respondent, the complainant and other reasonably identified people with relevant information, including witnesses identified by the respondent. Investigation interviews must be recorded and transcribed. Interviewees must be given the transcript for correction, and the corrected transcripts and numbered exhibits become part of the institutional record.
The respondent may not attend witnesses’ interviews but must receive a transcript of those interviews. The respondent also must receive the draft investigation report and access to the research records and evidence considered by the committee, subject to the rule’s procedures. The respondent generally has 30 days to comment on the draft report.
The institution must complete all aspects of an investigation within 180 days unless ORI grants an extension. If more time is needed, the institution must request an extension in writing and explain the circumstances warranting it.
Protections and confidentiality limits
The rule gives respondents opportunities to answer allegations and comment on reports. Decision-makers must consider admissible, credible evidence of honest error or a difference of opinion when evaluating the case.
During a proceeding, disclosure of the identities of respondents, complainants and witnesses is limited, as far as possible, to people who need to know and as allowed by law. That group may include institutional review boards, journals, editors, publishers, co-authors and collaborating institutions. Records that could identify research subjects receive additional confidentiality protection.
Confidentiality is not absolute. The rule permits institutions to manage published data or acknowledge that data may be unreliable, and institutions must provide information to ORI during federal oversight. The rule also does not require every institutional proceeding to be publicly disclosed.
Institutions must take reasonable and practical steps to protect good-faith complainants, witnesses and committee members from retaliation. Those protections do not guarantee anonymity or eliminate the possibility of workplace, professional or legal consequences when a matter is reported.
Why the rule matters beyond universities
Research-misconduct proceedings can affect patients, research participants, taxpayers and the public when unreliable data enter publications, grant applications, clinical research or public-health decision-making. The rule allows institutions and ORI to address potential risks to public health, research subjects, public safety, federal resources or possible legal violations through the applicable federal processes.
Institutions were required to update their written policies and procedures and submit revised policies with the annual report covering the 2025 reporting year, due April 30, 2026. For current cases, the practical result is a more explicit paper trail: institutions must document assessments, preserve evidence, report decisions to open investigations, record and transcribe investigation interviews, and maintain records that ORI can review.
ORI retains federal oversight authority, but it does not automatically redo every institutional investigation. Institutions have primary responsibility for the initial assessment, inquiry and investigation, while HHS may review the institutional record, conduct its own work when authorized and take appropriate administrative action.
What researchers should check
Researchers supported primarily by the National Science Foundation should not assume this HHS process applies. NSF uses its own research-misconduct regulation for NSF-funded work and directs allegations involving NSF applicants and awardees to its Office of Inspector General.
For researchers and institutions, the first practical question in a new case is therefore not simply whether NIH money was involved. It is which federal agency’s rules apply, when the allegation was received, whether the conduct fits the narrow federal definition of research misconduct, and what records must be preserved from the outset.
