Does the shape of the copper intrauterine device play a role in expulsion? Results from the ongoing European Active Surveillance Study on LCS12.

OBJECTIVE: To compare the incidence of expulsion for different copper intrauterine device (IUD) shapes. STUDY DESIGN: We conducted a secondary analysis of the ongoing, prospective, non-interventional European Active Surveillance Study on LCS12 (EURAS-LCS12). Users of newly inserted IUDs were recruited in 10 European countries via a network of approximately 1200 clinicians. We restricted the analysis to copper IUD users. In the main analysis, we classified copper IUDs by shape [Nova-T frame, Tatum-T frame, Multiload frame, frameless IUDs and intrauterine balls], without differentiation of size. We calculated the cumulative incidence, crude, and adjusted hazard ratios for expulsion. Covariates included in the adjusted analyses were age, BMI, parity, education, income, IUD user status, marital status, length of device, heavy menstrual bleeding, and clinician's experience. RESULTS: We included 26,381 copper IUD users from the EURAS-LCS12 dataset for this study. The most frequently used IUD shape was the Nova-T frame (14,724 [55.8%]) followed by the Tatum-T frame (4276 [16.2%]), frameless IUDs (3374 [12.8%]), Multiload frame (2962 [11.2%]), and intrauterine balls (IUBs) (1045 [4.0%]). Cox regression analysis regarding expulsions yielded an adjusted hazard ratio of 0.8 (95% CI, 0.7-1.0), 1.3 (95% CI, 1.0-1.8), 1.6 (95% CI, 1.2-2.1) and 3.6 (95% CI, 2.7-4.9) for Nova-T frame IUD, frameless IUDs, Multiload frame IUDs and IUBs versus Tatum-T frame IUD, respectively. CONCLUSION: The risk of expulsion following placement of a copper IUD is related to IUD shape, with Nova-T frame and Tatum-T frame IUDs demonstrating the lowest risk. IMPLICATIONS: Our finding of a higher risk of expulsion observed with Multiload frame, frameless, and intrauterine ball copper IUDs compared to Tatum-T frame and Nova-T frame devices during real world use has clinical importance. Clinicians may choose to use these data when counseling patients.

Pregnancy and pregnancy outcomes in a prospective cohort study: Final results from the Nexplanon Observational Risk Assessment Study (NORA).

OBJECTIVES: To monitor pregnancy occurrence and outcomes among Nexplanon users in the United States during standard clinical practice. STUDY DESIGN: The Nexplanon Observational Risk Assessment (NORA) study was a large prospective cohort study conducted in the United States (US). Study participants with a newly inserted Nexplanon implant were recruited by health care professionals (HCPs) who had completed the Nexplanon clinical training. Via a survey, study participants were followed up at 6-month intervals for 36 months and 6 months after implant removal. Reported unintended pregnancies were validated and classified as noninsertion, preinsertion, during-use, or postremoval. RESULTS: Four hundred and twenty-eight HCPs in 47 states recruited 7364 Nexplanon users. Pregnancies included one noninsertion, eight preinsertion, three during-use, and 14 postremoval pregnancies; of these 26 pregnancies, 22 resulted in the birth of a healthy child, two resulted in an induced abortion, one resulted in a spontaneous abortion, and one resulted in an ectopic pregnancy. Six pregnancies occurred during-use (n = 3) or within 7 days following implant removal (n = 3), yielding a Pearl Index of 0.04 (95% CI, 0.02-0.09). CONCLUSIONS: Nexplanon is an effective contraceptive in real-world users; the Pearl Index was 0.02 (95% CI, 0.00-0.06) for during-use pregnancies, and 0.04 when including pregnancies that occurred within 7 days following implant removal. IMPLICATIONS: This large real-world-use study indicates that Nexplanon is as effective as shown in the preapproval clinical trials.

Risk of depression and anemia in users of hormonal endometriosis treatments: Results from the VIPOS study.

OBJECTIVE: Dienogest (DNG) 2 mg (Visanne) was launched for endometriosis treatment in Europe in 2010. The Visanne Post-approval Observational Study (VIPOS) was designed to assess the safety of DNG 2 mg/day compared to other hormonal endometriosis treatments, focusing especially on clinically relevant depression and anemia. STUDY DESIGN: Large, prospective, non-interventional, active surveillance study in six European countries. Participants were recruited via gynecologists or specialized centers routinely prescribing endometriosis medication. Self-administered questionnaires during study entry and follow-up collected information on baseline characteristics, health status and endometriosis treatment. Patient-reported anemia and depression cases were validated by health care professionals. Inferential statistics were based on Cox proportional hazards models and crude and adjusted hazard ratios (HR) between cohorts were calculated (including 95% confidence intervals [CI]). Adjustment for potential confounding was performed by including predefined prognostic factors as covariates in the Cox models. RESULTS: Out of 26,430 participants, 11.4% used DNG, 12.8% used other approved endometriosis medications (OAED) and 75.7% used hormonal treatments not approved but frequently used for endometriosis treatment (NAED). At baseline, DNG users more frequently reported a surgically confirmed endometriosis diagnosis, severe endometriosis-associated pain and a history of depression, compared to the other cohorts. Baseline characteristics showed large inter-country variability. Overall, the number of confirmed anemia and depression events were substantially lower than expected. The adjusted HRs for anemia were 1.1 (95% CI, 0.4-2.6) for DNG vs OAED and 1.3 (95% CI, 0.7-2.4) for DNG vs NAED. The adjusted HRs for new or worsening depression were 1.8 (95% CI, 0.3-9.4) for DNG vs OAED and 1.5 (95% CI, 0.8-2.8) for DNG vs NAED. CONCLUSION: The main limitations encountered (low number of confirmed events and considerable inter-country variability) made a robust statistical analysis and a solid interpretation of the results challenging. However, no safety signal regarding anemia for DNG users could be detected, whereas a slight increase in depression risk cannot be excluded but might be explained by baseline severity of endometriosis or unknown country-specific confounding variables. VIPOS reflected routine use of hormonal endometriosis medications and provided real-world insights into endometriosis management in Europe.

Real world data on Nexplanon® procedure-related events: final results from the Nexplanon Observational Risk Assessment study (NORA).

OBJECTIVES: We conducted this study to characterize the frequency of insertion-, localization- and removal-related events and their clinically significant consequences among Nexplanon® (etonogestrel radiopaque contraceptive implant) users in the United States during standard clinical practice. STUDY DESIGN: The Nexplanon Observational Risk Assessment (NORA) study was a large, prospective cohort study conducted in the United States. A total of 428 Health Care Professionals (HCPs) who had completed the Nexplanon clinical training program recruited women who were newly prescribed Nexplanon. We collected data on insertion-, localization- and removal-related events experienced during routine clinical practice via questionnaires completed by patients and HCPs. Recruitment began in December 2011 and follow-up ended in October 2017. Data analysis characterized the frequency of procedure-related events. RESULTS: We collected data on 7364 insertion procedures. The incidence of incorrect insertion (i.e., initially unrecognized non-insertion, partial insertion or deep insertion) was 12.6 per 1000 insertions (95% CI, 10.2-15.5). Pins and needles/numbness in the arm/hand/fingers was the most common patient-reported event. We obtained data on 5159 removal procedures, of which all were successful but one (due to the location of the implant in deep muscle tissue). No implants were localized outside the arm. The most common challenge reported by HCPs during implant removal was encasement of the implant within fibrotic tissue. CONCLUSIONS: Events associated with the insertion, localization and removal of the Nexplanon contraceptive implant were rare and their clinical consequences were generally not suggestive of serious injury. IMPLICATIONS: This study is the largest prospective evaluation of events associated with insertion and removal of Nexplanon during routine clinical practice. It demonstrates that complications associated with insertion and removal of Nexplanon are rare when performed by trained clinicians.
