Intrauterine contraception: the role of general practitioners in four Dutch general practices.

The intrauterine device (IUD) use in the Netherlands and the United States is limited to a small group of women, though the risk of infection and pregnancy is small. Therefore, it was of interest to investigate the characteristics of women who choose an IUD as contraceptive method and the influence of general practitioners concerning IUD insertion. The aim of this retrospective cohort study was to assess differences between general practices and to investigate the characteristics of IUD users.
