Objective To determine intrauterine contraceptive device (IUCD) discontinuation rate and its causes and related factors among women attending the OPD/family planning clinic in Mahila Chikitasalaya, SMS Medical College, Jaipur from January 2012 to December 2012. Methods 387 women who had an intrauterine device (IUD) inserted during the last 1-5 years were interviewed during their visits to the OPD/family planning clinic. Sociodemographic characteristics for all women were described using frequency distribution. Life tables were used to describe the proportion of women who discontinued IUD at various time intervals. The main outcome measure was IUD discontinuation. Results The incidence of IUD discontinuation in the first year following insertion was 16.79 %. Approximately 31 % of the study sample continued using their devices after 5 years. The average duration of IUD use was 36 months. Of the 387 women, 56 % discontinued IUD use because of a desire to conceive, 27.7 % because of side effects, 15.36 % because of opposition from the woman's family, and 1.5 % because they were sexually inactive. The most common side effects reported as the reasons for discontinuation were bleeding, infection, and pain. Discontinuation was inversely related to the age at insertion, the number of living children, and the sex of children. Previous contraceptive users were significantly less likely to discontinue IUD use. Conclusions The crude cumulative rate of IUD discontinuation was 16.79 % during the first year, suggesting a need to tackle the problem of discontinuation through effective educational strategies and counseling techniques. Desire to have a male child still predominates among Indian families. The average duration of IUD use in majority of the females was about 36 months (45 %), thereby fulfilling its objective of spacing between children as laid down by the WHO (2 years spacing between pregnancies). About 31 % of the women continued using IUCD even after 5 years. It is crucial to correct misconceptions and identify the lack of correct and complete information both among the providers and the acceptors, to improve the effectiveness of family planning programs.
