[BDSP. Notice produite par INIST SR0xyS2J. Diffusion soumise à autorisation]. Background. Induced abortion rates have declined in Finland since 1973. A possible explanation offered has been that of deteriorating data collection. Methods. To assess the completeness of the Register, we compared the information from a consecutive sample of hospital records (N=482) to the Finnish Abortion Register in 18 hospitals in three counties. A smaller consecutive sample (N=345) was collected from the same hospitals to assess the validity of the Register information. Results. Only five abortions (1%) found in the hospitals were not reported in the Abortion Register. A total of 95% of all Register information was identical to that in the medical records. There were quality problems in reporting some variables : the length of pregnancy (definition problems), the classification of the abortion procedure, and social class (out-of-date classifications). Furthermore, early complications were poorly reported. Conclusions. The data from the Finnish Abortion Register are a reliable source for monitoring trends in the abortion rate and its variation by subgroups, but are an unreliable source for the study of the medical aspects of induced abortion.
