Strong decline in female sterilization rates in Norway after the introduction of a new copayment system: a registry based study

BMC Womens Health. 2007 Aug 27;7:12. doi: 10.1186/1472-6874-7-12.


Background: January 1, 2002, copayment for outpatient female sterilization in Norwegian public hospitals increased from 33 euro to 750 euro after a revision of the health care system. The aim of the present study was to investigate the effect of the new copayment system on female sterilization epidemiology.

Methods: We retrieved data on all female sterilizations 1999-2005 (N = 23 1333) from the Norwegian Patient Register, an administrative register to which it is mandatory for all hospitals to report. Sterilizations with diagnostic codes indicative of vaginal delivery, caesarean section, spontaneous abortion, ectopic pregnancy, and termination of pregnancy were analyzed separately. All other sterilizations were defined as "interval sterilization".

Results: An abrupt fall in female sterilization was observed after the raise in copayment. Age-adjusted incidence rates dropped from 6.3-6.8 per 1000 women in 1999-2001 to 2.2-2.3 per 1000 women during 2002-2005. Interval sterilizations dropped to 25% of the previous level after the rise in copayment while sterilizations in conjunction with caesarean section and postpartum sterilization remained constant.

Conclusion: For many Norwegian women seeking contraception, sterilization is no longer an available alternative.
