OBJECTIVES: Organised, nationwide screening for breast cancer with mammography in the age group 45-65 years with 2 years screening interval started in Hungary in January 2002. According to the Hungarian guideline on mammography screening, an accredited mammography screening centre should perform 10000 examinations annually. The aim of this study is to analyze the quality control indicators of this screening programme. METHODS: The data derive from the financial database of the National Health Insurance Fund Administration (NHIFA) covering the period 2002-2010 year. We analysed 3 selected years: 2002, 2005 and 2010. The main indicator was the number of mammography screening examinations performed by the mammography screening centres. RESULTS: The annual number of mammography examinations was 323537 in 2002, 247045 in 2005 and 242601 in 2010. The number of accredited mammography screening centres were 51 (2002), 41 (2005) and 40 (2010). The average number of mammography examinations were 6344 (2002), 6025 (2005) and 6065 (2010) per year. In 2002, 14 mammography centres performed 10000 examinations in a range from 10314 to 25940. In 2005 only 4 mammography centres achieved more than 10000 examinations per year (range: 10294-17845). In 2010 again only 4 mammography centres achieved more than 10000 examinations per year (range: 10239-19259). CONCLUSIONS: Only a few number of mammography centres met the recommendation of the Hungarian mammography screening guideline and reached the target (10000 mammography examinations annually). Most of the mammography centres are not able to comply with professional guideline.
