Death

A Tragedy Baby girl Born September 2, 1999 Died December 17, 1999 Cause of death: acute hepatitis B infection

Why Did This Tragedy Occur? Birth dose was not given Mom tested HBsAg (+) prenatally Prenatal care provider –Reported it to the hospital as HBsAg (-) –Did not report the HBsAg (+) to the LHD –Did not send a hard copy of the HBsAg test results to the hospital

What Can We Do? Identify and review all HBsAg (+) results for women of childbearing years –First time reported –Reported before (ask the patient/doc if she is pregnant)? Make sure there are policies in place and information is shared between departments

What Else Can We Do? Continue to provide education on HBsAg reporting –Prenatal care providers –Hospitals –Laboratories –Private doctors Ensure compliance
