Design outcomes

Primary

MeasureTime frame
Expected outcome 1: Acceptability of the LNG-IUS and the Implanon when offered as a free choice and without cost to women in the public sector must be higher than the TCu380A IUD: almost of the 70% of new contraceptives available at the Outpatient clinic will be choose a LNG-IUS and Implanon, whereas 30% of women will choose TCu380A IUD; and could be higher when compared to those who choose short acting reversible contraceptive methods (oral contraceptives, injectables, and vaginal ring) (70% vs. 40%);Outcome observed1: We enrolled a total of 609 women. A total of 358/609 women (58.8%) choose the ENG-implant and 251/609 (41.2%) choose SARC methods.

Secondary

MeasureTime frame
Expected outcome 2: The continuation rate of the LNG-IUS, Implanon and TCu 380ª IUD, when offered as free choice and without cost to women at the public sector, may be similar: almost 80% of continuation up to the first year and 60% up to the second year; and must be higher when compared to those who choose SARC methods (oral contraceptives, injectables, and vaginal ring) (80% vs. 40%);Outcome observed 2: We observed a peak of discontinuation of the ENG-implant users at month 15 of the study whereas among users of the SARC methods the high discontinuation occurs at months 3 and 6. Continuation rate was higher among users of the ENG-implant (89.9% [322/358] and 75.4% [270/358]) when compared to users of SARC methods (27.2% [69/251] and 15.9% [40/251]) up to one and two years after the study initiation, respectively. ;Expected outcome 3: The main reasons for removal for each intrauterine method must be irregular bleeding, pain and expulsion, whereas for Implanon the main reason of discontinuation must be irregular bleeding; ;Outcome observed 3: The main reasons for discontinuation among users of the LNG-IUS and the TCu380A IUD were irregular bleeding, pain and expulsion whereas for the Implanon the main reason for discontinuation was irregular bleeding; ;Expected outcome 4: The main reason of discontinuation of the SARC methods (combined oral contraceptives, injectables and vaginal ring) may be irregular bleeding, dizziness, pain and abdominal pain;Outcome observed 4: The main reason of discontinuation of the SARC methods (combined oral contraceptives, injectables and vaginal ring) were irregular bleeding, dizziness, pain and abdominal pain, and acne;;Expected outcome 5: The women´s groups must be satisfied with the chosen contraceptive in a proportion of 80% for the LARCs and 60% for the SARC methods.;Outcome observed 5: Satisfaction was high in both group of users; however, users of the ENG-implant reported satisfaction rate of 83.2% and 82.2% when compared to 92.8%
