Intrauterine device continuation rates and reasons for discontinuation in a Central European clinic with a high standard of care and ultrasound follow-up: a retrospective cohort study

Factors Predicting Removals of the Levonorgestrel-Releasing Intrauterine System in an Adolescent Cohort

OBJECTIVE

Use of 52-mg levonorgestrel intrauterine system (LNG-IUS) in adolescents for heavy menstrual bleeding (HMB), dysmenorrhea, and contraception has increased, yet little is known about the factors predicting removal and dissatisfaction in adolescents. The aim of this study was to identify factors predicting LNG-IUS removal in adolescents.

METHODS

This was a retrospective cohort study including all adolescents (9-19 years) who underwent LNG-IUS insertion between 2012 and 2021 (n = 536). A medical record review was conducted and data were collated on medical and gynecological history, age, indications for insertion, complications, expulsions, and removals. The data were analyzed using χ2 tests.

RESULTS

Indications for LNG-IUS insertions (n = 536) among 517 individual patients (n = 517) included menstrual management (n = 142), HMB alone (n = 118), HMB and pelvic pain/dysmenorrhea (n = 105), dysmenorrhea/pelvic pain alone (n = 47), and contraception (n = 16). Associated diagnoses included intellectual disability (44.29%, 229/517), chronic pain conditions (12.77%, 66/517), and additional mental health concerns (24.37%, 126/517). Patient dissatisfaction with LNG-IUS led to removal in 61 (11.38%), mostly for pain or persistent bleeding. Higher removal rates occurred in those with associated chronic pain conditions (46.97%, χ2 = 55.9, P < .05), mental health concerns (16.67%, χ2 = 5.06, P < .05), and bleeding disorders (26.32%, χ2 = 5.09, P < .05). Among the cohort with an intellectual disability, lower rates of removal occurred (5.7%, χ2 = 11.2, P < .05). Whereas the LNG-IUS removal rate among gender-diverse youth was 23.07%, this was not statistically significant. Younger age was also not associated with a statistically significant increase in removals (13.72%, χ2 = 0.73, P > .05).

DISCUSSION

Adolescents have a low dissatisfaction and removal rate (11.38%) of LNG-IUS. Chronic pain, bleeding tendency, and mental health concerns are associated with higher removal rates and intellectual disability with lower rates. These findings are useful in counselling patients and families about LNG-IUS.

Office hysteroscopy to guide intrauterine device hook use for the removal of a deeply embedded intrauterine device

Office hysteroscopy is a common examination method in gynecological clinics. In most cases, it can only be examined but not treated. Here, we present our specific technique used office hysteroscope to guide intrauterine device (IUD) hook in the removal of deeply embedded IUD which provided direct visualization and sufficient force.

Immediate Postpartum Insertion of Copper Intrauterine Device in a Brazilian University Hospital: Expulsion and Continuation Rates

OBJECTIVE

 To evaluate the expulsion and continuation rates of the copper intrauterine device (IUD) inserted in the immediate postpartum period in a Brazilian public university hospital.

MATERIALS AND METHODS

 In the present cohort study, we included women who received immediate postpartum IUD at vaginal delivery or cesarean s March 2018 to December 2019. Clinical data and the findings of transvaginal ultrasound (US) scans performed 6-weeks postpartum were collected. The expulsion and continuation rates were assessed 6-months postpartum using data from the electronic medical records or by telephone contact. The primary outcome was the proportion of IUDs expelled at 6 months. For the statistical analysis, we used the Student t-test, the Poisson distribution, and the Chi-squared test.

RESULTS

 There were 3,728 births in the period, and 352 IUD insertions were performed, totaling a rate of 9.4%. At 6 weeks postpartum, the IUD was properly positioned in 65.1% of the cases, in 10.8% there was partial expulsion, and in 8.5% it had been completely expelled. At 6 months postpartum, information was obtained from 234 women, 74.4% of whom used IUD, with an overall expulsion rate of 25.6%. The expulsion rate was higher after vaginal delivery when compared with cesarean section (68.4% versus 31.6% respectively; p = 0.031). There were no differences in terms of age, parity, gestational age, final body mass index, and newborn weight.

CONCLUSION

 Despite the low insertion rate of copper IUDs in the postpartum period and a higher expulsion rate, the rate of long-term continuation of intrauterine contraception was high, indicating that it is a useful intervention to prevent unwanted pregnancies and to reduce short-interval birth.

Topical reinforcement of the cervical mucus barrier to sperm

Close to half of the world's pregnancies are still unplanned, reflecting a clear unmet need in contraception. Ideally, a contraceptive would provide the high efficacy of hormonal treatments, without systemic side effects. Here, we studied topical reinforcement of the cervical mucus by chitosan mucoadhesive polymers as a form of female contraceptive. Chitosans larger than 7 kDa effectively cross-linked human ovulatory cervical mucus to prevent sperm penetration in vitro. We then demonstrated in vivo using the ewe as a model that vaginal gels containing chitosan could stop ram sperm at the entrance of the cervical canal and prevent them from reaching the uterus, whereas the same gels without chitosan did not substantially limit sperm migration. Chitosan did not affect sperm motility in vitro or in vivo, suggesting reinforcement of the mucus physical barrier as the primary mechanism of action. The chitosan formulations did not damage or irritate the ewe vaginal epithelium, in contrast to nonoxynol-9 spermicide. The demonstration that cervical mucus can be reinforced topically to create an effective barrier to sperm may therefore form the technological basis for muco-cervical barrier contraceptives with the potential to become an alternative to hormonal contraceptives.

Patient acceptability, continuation and complication rates with immediate postpartum levonorgestrel intrauterine device insertion at caesarean section and vaginal birth

BACKGROUND

Immediate postpartum long-acting reversible contraception (LARC) has been shown to reduce unintended pregnancy but uptake of this type of contraception in Australia is low compared to European counterparts.

AIMS

To assess self-reported continuation rates, complications and satisfaction in patients having immediate postpartum hormonal intrauterine device (IUD) inserted at caesarean section (CS) or after vaginal birth (VB).

MATERIALS AND METHODS

Retrospective cohort study of all patients with immediate postpartum hormonal IUD insertion over three years at a tertiary maternity service. Primary outcomes were patient satisfaction, continuation and expulsion rates. Secondary outcomes were reason for discontinuation, patient-reported complications, attendance for postpartum check with a general practitioner (GP) and rate of unplanned pregnancy. Simple descriptive statistics were used to analyse the data.

RESULTS

One hundred and ninety-three women had a hormonal IUD inserted and 143 consented to involvement (CS n = 79; VB n = 64). Six and 12 months continuation rates for CS were 60.8% and 54.4%, and VB were 46.9% and 39.1%. The most common reasons for removal were: pain (34.5%), heavy or irregular bleeding (25.9%) and partial expulsion (24.1%). Expulsion was more likely after VB (34.1%) than CS (10.1%), (odds ratio 2.72; 95% CI 1.07-6.90; P = 0.036). There were 60.8% of women post-CS and 56.3% of women post-VB who were satisfied with their decision to have immediate postpartum insertion and most women attended routine postpartum follow-up with their GP (89.5%).

CONCLUSION

Immediate postpartum hormonal IUD insertion in this cohort is associated with higher rates of expulsion and lower satisfaction rates compared to those documented in the literature for delayed postpartum insertion cohorts.

Discontinuation rates of intrauterine contraception due to unfavourable bleeding: a systematic review

OBJECTIVE

Levonorgestrel-releasing intrauterine devices (LNG-IUDs) and copper intrauterine devices (Cu-IUDs) offer long-acting contraception; however, some women may discontinue use within the first year due to bleeding pattern changes, limiting their potential. This systematic literature review investigated whether differences in bleeding profiles influence continuation rates in women in America, Europe and Australia.

METHODS

Searches performed in PubMed and Embase were screened to identify publications describing bleeding patterns and rates of early IUC removal/discontinuation or continuation, descriptions of bleeding patterns, reasons for discontinuation, and patient satisfaction, acceptability and tolerability for LNG-IUDs and Cu-IUDs published between January 2010 and December 2019. The results were further restricted to capture citations related to 'Humans' and 'Females'. The review was limited to studies published from 2010 onwards, as changing attitudes over time mean that results of studies performed before this date may not be generalizable to current practice.

RESULTS

Forty-eight publications describing 41 studies performed principally in the USA (n = 17) and Europe (n = 13) were identified. Publications describing bleeding patterns in LNG-IUD users (n = 11) consistently observed a reduction in bleeding in most women, whereas two of three studies in Cu-IUD users reported heavy bleeding in approximately 40% of patients. Rates of discontinuation for both devices ranged widely and may be as high as 50% but were lower for LNG-IUDs versus Cu-IUDs. Discontinuation rates due to bleeding were consistently higher for Cu-IUDs versus LNG-IUDs.

CONCLUSIONS

Bleeding is a common reason for discontinuation of Cu-IUDs and LNG-IUDs. The more favourable bleeding pattern observed in LNG-IUD users may be associated with a lower rate of early discontinuation of LNG-IUDs versus Cu-IUDs.

Contraceptive method preference and reasons for contraceptive discontinuation among women randomized to intramuscular depot medroxyprogesterone acetate, a copper intrauterine device or a levonorgestrel implant: Findings from Durban, South Africa

OBJECTIVES

The use of intrauterine devices (IUDs) and contraceptive implants in South Africa is low with limited data on patterns of use and reasons for discontinuation. We describe contraceptive preferences and reasons for discontinuation among women enrolled in the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial from one trial site.

STUDY DESIGN

ECHO, conducted between 2015 and 2018, enrolled and randomized sexually active women, aged 16 to 35, and desiring contraception, to intramuscular depot medroxyprogesterone acetate (DMPA-IM), a copper intrauterine device (copper-IUD) or a levonorgestrel (LNG) implant; follow-up was 12 to 18 months. We interviewed 829 women at the Durban, South Africa trial site at ECHO Trial exit to ascertain contraceptive preferences at randomization. Reasons for randomized contraceptive discontinuation were collected at ECHO Trial exit and 6 months later. Data were analyzed descriptively.

RESULTS

At the final ECHO Trial visit, among women using their randomized contraceptive method (n = 757), 21% discontinued DMPA-IM, 20% discontinued LNG implant and 22% discontinued the copper-IUD. About a quarter from each group discontinued due to problems with bleeding. Among women continuing their randomized contraceptive at trial exit (n = 597), 25% discontinued DMPA-IM within 6 months of exiting the study, 8% discontinued LNG implant and 4% discontinued copper-IUD. A third of women reported wanting to be assigned DMPA-IM at randomization, 20% wanted the LNG implant and 18% the copper-IUD.

CONCLUSIONS

Despite some women having preferences about which contraceptive they might be randomized to, discontinuation rates for all three methods at ECHO Trial exit and 6-month post-trial follow-up were low.

IMPLICATIONS

Despite limited prior use of IUDs and implants among women enrolled in this study, and a desire by some women to not receive these methods at randomization, discontinuation rates remained low. The provision of quality contraceptive counselling and support may increase uptake and continued use of implants and IUDs.

Copper IUD continuation, unwanted effects and cost consequences at 1 year in users aged under 30 - a secondary analysis of the EURAS-IUD study

OBJECTIVE

To conduct a secondary analysis of continuation, unwanted effects and cost consequences at 1 year in copper intrauterine device (IUD) users aged under 30 in the European Active Surveillance Study for Intrauterine Devices (EURAS-IUD study) based on IUD type.

METHODS

Descriptive and comparative analyses of copper IUD continuation, unwanted effects and estimated cost consequences at 1 year were performed in users aged under 30 based on IUD copper surface area, shape or design, width and arms' flexibility.

RESULTS

5796 copper IUD users were identified to have been aged under 30 at EURAS-IUD study recruitment and data for 5762 users (99.4%) was analysed. Higher IUD continuation, fewer unwanted effects and lower costs were observed with IUDs of the lowest copper content (<300mm²), horse-shoe frame design, widths 18 mm to <30mm and flexible IUD arms. Discontinuation, unwanted effects and costs were greater with frameless IUDs and framed, ≥30mm width IUDs with 380mm² of copper and copper bands on their rigid transverse IUD arms.

CONCLUSIONS

Significant differences in continuation, reported unwanted effects and estimated costs at 1 year between IUD types were observed in users aged under 30. Although further research is needed, clinicians should consider these findings when counselling and choosing IUD types for younger women.

Long-acting reversible contraception side effect management

PURPOSE OF REVIEW

Long-acting reversible contraception (LARC) is increasingly used by adolescents and young adults (AYAs). Subsequent to LARC insertion, AYAs are presenting to their primary care providers with LARC concerns. This article seeks to equip primary care clinicians with the tools necessary to assess and manage common LARC-associated side effects.

RECENT FINDINGS

Side effects are common with progestin-only LARC, and can precipitate early discontinuation of an otherwise effective, low-maintenance form of contraception. Abnormal uterine bleeding, pelvic pain, acne, and weight change are often cited as progestin-only LARC side effects, yet the causes are poorly understood despite extensive research. While most side effects improve with time, therapeutic interventions are available for patients with undesirable side effects that prefer medical management. Research emphasizes the importance of proper patient counseling and clinical follow-up.

SUMMARY

Counseling remains essential in the management of LARC-associated side effects. However, options are available to temporarily mitigate such side effects and increase LARC satisfaction. While these therapeutic options are prescribed based on expert opinion, such regimens remain inadequately studied in AYA populations.

International Perspectives: IUDs and Adolescents

Unplanned or unwanted pregnancy among adolescents is a worldwide public health issue. In many countries unmarried young women are denied contraceptive services. Long-acting reversible contraceptive methods such as the intrauterine devices (IUDs) have been shown to be more effective than short-acting such as the pill, and safe also for adolescents. The popularity has varied a lot with time and between populations. Health care providers, health system, and user factors all influence IUD use. A good sexuality education through school provides a foundation, and health care providers give specific individual counseling. International and country-specific guidelines have been published during the past decade indicating the advantage of IUDs. New smaller size devices make placement easier for nulliparous adolescents. Still the uptake has remained rather low in most regions, cost being one barrier. Several municipalities have started to provide long-acting reversible contraceptive methods for adolescents free of charge, and this has led to a significant increase in IUD use, accompanied by a reduction in abortion rates. Adolescent-friendly services should offer low-cost or free contraception, including male and female condoms, emergency contraception, and a full range of modern methods, including long-acting reversible methods, according to adolescents' preferences and needs.
