Factors associated with discontinuation among long-acting reversible contraceptive users: a multisite prospective cohort study in urban public health facilities in Ethiopia

Abstract

ObjectiveThe study aims to determine discontinuation among long-acting reversible contraceptive users at 3, 6, 9 and 12 months after initiation and its associated factors among new long-acting reversible contraceptive (LARC) users.DesignA facility-based multicentre prospective cohort study was conducted with a sample size of 1766 women.SettingThe study was conducted in five large cities of Ethiopia (Addis Ababa, Gondar, Mekelle, Jimma and Harar) between March 2017 and December 2018. Various referral hospitals and health centres that are found in those cities are included in the study.ParticipantsThe study population was all women who were new users of LARCs and initiated LARCs in our selected public health facilities during the enrolment period.InterventionsA pretested structured questionnaire was administered at enrolment and at 6 and 12 months to determine discontinuation proportion and factors associated with discontinuation.ResultFrom the total of 1766 women sampled for the study only 1596 (90.4%) participants completed all the questionnaires including the 12-month follow-up study. The overall proportion of discontinuation of LARCs at 12 months was 21.8% (95% CI 19.8 to 23.9). The overall discontinuation proportions at 3, 6, 9 and 12 months were 2.94%, 8.53%, 3.94% and 6.36%, respectively. Location of method initiation (adjusted HR (aHR)=5.77; (95% CI 1.16 to 28.69)) and dissatisfaction with the method (aHR=0.09; (95% CI 0.03 to 0.21)) were found to be the predictors of discontinuation among intrauterine contraceptive device users. Being satisfied with the method (aHR=0.21; (95% CI 0.15 to 0.27)), initiation after post abortion (aHR=0.48; (95% CI: 0.26, 0.89)) and joint decision with partner for method initiation (aHR=0.67; (95% CI: 0.50, 0.90)) were inversely associated with implant discontinuation.ConclusionThe majority of LARC users discontinue the method in the first 6 months after insertion and dissatisfaction with the method increased the likelihood of removal during the first year of LARC use.
