title: [SAMDATA--hospital statistics without quality assurance].
abstract: The author discusses problems related to systematic bias in the hospital information used for official statistics, SAMDATA. The lack of systematic evaluation of information on hospital diagnosis is a serious disadvantage when using the information to compare hospital diagnosis in different counties and over time. Another problem is lack of adequate standardization of the data by age and sex.
