Isolation of HBV+ Patients

To isolate HBsAg positive patients… dedicate machines, equipment, instruments, supplies,

and medications that will not be used by HBV susceptible patients.

Interpretive Guidance § 494.30(a)(1)(i)

Separate dedicated supplies and equipment, including blood glucose monitors, must be used to

provide care to the HBV+ patient. All supplies used in the isolation room/area, such as clamps,

blood-pressure cuffs, testing reagents, etc., should be labeled “isolation” and not routinely

removed from the isolation room/area.

Refillable concentrate containers must be surface disinfected at the completion of each

treatment. They may be kept in the isolation area and refilled at the door or removed for

cleaning and disinfection. In the disinfection area, the “isolation” container(s) and pick-up

tube(s) must be segregated in a dedicated, designated area away from all other containers and

pick-up tubes. If the container/pick-up tube is to be rotated out of the isolation area, it must be

bleached before subsequent use.

Separate gowns should be used in the isolation area and removed before leaving the isolation

area/room. Anyone entering the isolation area/room during the patient’s treatment must wear a

protective gown.

HBV+ patients must undergo dialysis on dedicated machines. Due to the risk of cross-contamination, facilities should avoid switching equipment used for HBV+ patients for use with

HBV- patients.

Equipment used by HBV+ patients should be reserved for them unless repair or maintenance is

needed or until all HBV+ patients have been discharged.

Based on CDC guidance, dialyzers for HBV+ patients must not be reused. Refer to V301 under

Reuse.

When the machine is no longer dedicated to an HBV+ patient, its internal pathways can be

disinfected using conventional protocols, its external surfaces can be cleaned and disinfected,

and it can be returned to general use.
