An employee suffered a workplace injury that led to a blood spill, and coworkers cleaned up the blood (we don't yet know what, if any precautions were taken by the coworkers).
Employer has a self-insured group health plan and, in its capacity as sponsor of the health plan, learned after the accident that the injured employee is HIV positive and has advanced stage AIDS. Employer has asked whether it can disclose to the exposed coworkers the fact that the blood to which they were exposed contained the AIDS virus, assuming the employee does not authorize the disclosure. The coworkers know whose blood it was.
45 CFR §164.512(j)(1)(i) allows disclosure of PHI without authorization if the covered entity, in good faith, believes that the disclosure "is necessary to prevent or lessen a serious and imminent threat to the health or safety of a person or the public" and "the disclosure is to a person or persons reasonably able to prevent or lessen the threat, including the target of the threat."
The preamble to the regulations focus on physical threats to others (e.g. violence), and note that the exception would apply in "rare circumstances." However, the preamble also notes that "it would be impossible to enumerate all of the scenarios that may warrant disclosure of PHI pursuant to this section."
In the discusion of the benefits and costs of the Privacy Rule, the preamble notes that "Early detection is essential for the survival of a person with HIV." Assuming that a person exposed to the blood of a person with AIDS could himself contract the disease (through a wound or contact with the eyes or mucous membranes), and that early detection is important to prolonging life, it would seem that notification (and subsequent testing of those who were exposed) would be necessary to lessen the "threat" posed by the exposure.
The HIPAA hotline was not helpful, and there are no HHS Q&A's explaining this exception.
Thanks in advance for any thoughts.
