Case report associates acute hepatitis B infection with shared glucometer use in nursing home

A field report from a skilled nursing facility in North Carolina describes a case of acute hepatitis B virus infection in a nursing home resident. The infection was temporally associated with assisted blood glucose monitoring using a glucometer that was shared with another resident known to have chronic hepatitis B infection. The report does not provide specific sample size, follow-up duration, or quantitative effect measures for the association.

No safety, adverse event, or tolerability data were reported for this case. The report did not describe any comparator group or control measures in place at the time of the incident.

Key limitations include the nature of the evidence as a single case report, which can only describe an association and cannot establish causation. The absence of reported genetic sequencing to confirm viral linkage between the two residents further limits the strength of the conclusion. Funding sources and author conflicts of interest were not reported.

For clinical practice, this report serves as a reminder of the theoretical risk of bloodborne pathogen transmission via shared medical equipment, even in non-traditional healthcare settings like nursing homes. It underscores the importance of adhering to standard infection control protocols, including device disinfection or use of single-patient devices when possible, though the direct evidence from this case remains anecdotal.
