Tauranga Hospital case notes and electronic records were reviewed retrospectively (2002–7) for inpatient episodes coded as either liver cell carcinoma, unspecified carcinoma, liver failure, cirrhosis and several other related codes. HBsAg+ individuals from the Medlab database (2002–7) were cross-referenced against the National Database of HBsAg+ persons, to find those not known. The aims of the study were to screen for hepatomas more effectively at Tauranga Hospital and to improve HBsAg+ patient referral rates to the hepatitis foundation. Six hepatomas were identified secondary to HBV, one in a screening programme of 6 monthly ultrasounds and serum alpha-fetoprotein measurements. Medlab identified 1761 HBsAg+ individuals, of which only 1295 were known to the national database.
