Contraceptive switch and abandonment among women using the pill, condoms and injectables in Brazil

Objective The aim of our study was to assess the covariates of contraceptive switching and abandonment among Brazilian women stratified by oral pills, condoms and injectables. Materials and Methods Women attending primary health care services in three Brazilian mid- to large-sized cities were interviewed face-to-face about their contraceptive practices (n = 2,051). Data were collected using a contraceptive calendar. Analysis included estimates using Kaplan-Meier multiple-decrement life-table probabilities and discrete-time hazards modelling of switching from a method to another or to no method. Results Among 3,280 segments of contraceptive use, we observed that five-year contraceptive switching rates ranged from 34.9% among injectable users to 56.1% among pill users. Of particular concern were the high discontinuation rates of abandonment, which ranged from 50.9% among injectable users to 77.4% among pill users. Covariates of method switching and abandonment varied by type of method, but age, race/ethnicity, religion and relationship status must be highlighted as key elements of discontinuation. Conclusion Contraceptive method switching and abandoning are frequent outcomes of contraceptive use. Understanding the factors that shape women’s decisions to continue or discontinue the use of a contraceptive method can help tailoring comprehensive contraceptive counselling that meet their expectations and reproductive needs when starting using a method.

The impact of community and provider-driven social accountability interventions on contraceptive use: findings from a cohort study of new users in Ghana and Tanzania

BackgroundAlthough contraceptive use has increased over 15 years, discontinuation rates remain high. Contraceptive use is becoming more important when addressing unmet need for family planning. Social accountability, defined here as collective processes for holding duty bearers to account for their actions, is a rights-based participatory process that supports service provision and person-centred care, as well as, informed decision-making among community members regarding their health. A study implemented in Ghana and Tanzania was designed to understand and evaluate how social accountability and participatory processes influences quality of care and client satisfaction and whether this results in increased contraceptive uptake and use. We report here on the relationship between social accountability and the use of modern contraceptives, i.e., contraceptive method discontinuation, contraceptive method switching, and contraceptive discontinuation.MethodsAs part of Community and Provider driven Social Accountability Intervention (CaPSAI) Project, a cohort of women aged 15 to 49 years who were new users of contraception and accessing family planning and contraceptives services at the study facilities across both intervention and control groups were followed-up over a 12-month period to measure changes contraceptive use.ResultsIn this cohort study over a one-year duration, we did not find a statistically significant difference in Ghana and Tanzania in overall method discontinuation, switching, and contraceptive discontinuation after exposure to a social accountability intervention. In Ghana but not in Tanzania, when stratified by the type of facility (district level vs. health centre), there were significantly less method and contraceptive discontinuation in the district level facility and significantly more method and contraceptive discontinuation in the health centres in the intervention group. In Ghana, the most important reasons reported for stopping a method were fear of side-effects, health concerns and wanting to become pregnant in the control group and fear of side-effects wanting a more effective method and infrequent sex in the intervention group. In Tanzania, the most important reasons reported for stopping a method were fear of side-effects, wanting a more effective method, and method not available in the control group compared to wanting a more effective method, fear of side-effects and health concerns in the intervention group.ConclusionsWe did not demonstrate a statistically significant impact of a six-month CaPSAI intervention on contraceptives use among new users in Tanzania and Ghana. However, since social accountability have important impacts beyond contraceptive use it is important consider results of the intermediate outcomes, cases of change, and process evaluation to fully understand the impact of this intervention.Trial registrationThe CaPSAI Project has been registered at Australian New Zealand Clinical Trials Registry (ACTRN12619000378123, 11/03/2019).

Contraceptive Method Switching and Long-Acting Reversible Contraception Removal in U.S. Safety Net Clinics, 2016-2021.

To describe patterns of contraceptive method switching and long-acting reversible contraception (LARC) removal in a large network of community health centers. We conducted a retrospective cohort study using individual-level electronic health record data from 489 clinics in 20 states from 2016 to 2021. We used logistic regression models, including individual-, clinic-, and state-level covariates, to calculate adjusted odds ratios and predicted probabilities of any observed contraceptive method switching and LARC removal among those with baseline incident LARC, both over 4-year time periods. Among 151,786 patients with 513,753 contraceptive encounters, 22.1% switched to another method at least once over the 4-year observation period, and switching patterns were varied. In patients with baseline LARC, the adjusted predicted probability of switching was 19.0% (95% CI 18.0-20.0%) compared with patients with baseline moderately effective methods (16.2%, 95% CI 15.1-17.3%). The adjusted predicted probability of switching was highest among the youngest group (28.6%, 95% CI 25.8-31.6% in patients aged 12-14 years) and decreased in a dose-response relationship by age to 8.4% (95% CI 7.4-9.4%) among patients aged 45-49 years. Latina and Black race and ethnicity, public or no insurance, and baseline Title X clinic status were all associated with higher odds of switching at least once. Among baseline LARC users, 19.4% had a removal (to switch or discontinue) within 1 year and 30.1% within 4 years; 97.6% of clinics that provided LARC also had evidence of a removal. Community health centers provide access to method switching and LARC removal. Contraceptive switching and LARC removal are common, and clinicians should normalize switching and LARC removal among patients.

Contraceptive method switching and discontinuation during the COVID-19 pandemic in Myanmar: findings from a longitudinal cohort study

The objective of this paper was to document contraceptive dynamics and associated correlates of contraceptive method switching and discontinuation in Myanmar during the COVID-19 pandemic. We conducted a secondary analysis of panel data collected between August 2020 and March 2021 among married women of reproductive age of households registered for a strategic purchasing project in Yangon. Statistical analysis included descriptive statistics, bivariate tests of association and adjusted log-Poisson models with generalised estimating equations to examine relative risks and 95% confidence intervals. Among the study sample, 28% of women reported method switching and 20% method discontinuation at least once during the study period. Difficulties accessing resupply/removal/insertion of contraception due to COVID-19 and method type at baseline were identified as correlates of method switching and discontinuation. Women who reported difficulty obtaining their method due to COVID-19 had an increased risk of method switching (RRadj: 1.85, 95%CI: 1.27, 2.71). Women who reported injectables as their initial contraceptive method at baseline had an increased risk of method switching (RRadj:1.71, 95%CI: 1.06, 2.76) and method discontinuation (RRadj: 2.16, 95%CI: 1.16, 4.02) compared to non-injectable users. As Myanmar evaluates its public health response to COVID-19, the country should consider innovative service delivery models that allow women to have sustained access to their method of choice during a health emergency.

Stop or Switch: Correlates of Stopping Use or Switching Contraceptive Methods While Wanting to Avoid Pregnancy in 48 Low- and Middle-Income Countries.

Contraceptive discontinuation for method-related reasons, while presumably wanting to avoid pregnancy, is a common phenomenon and can contribute to high levels of unmet need and unplanned pregnancies. Some women discontinue contraceptive use and do not quickly resume a method ("stopping"), while others are able to quickly switch to another method to achieve their reproductive goal of avoiding pregnancy ("switching"). We use Demographic and Health Survey data from 48 countries to examine what differentiates women who were able to switch to another method versus those who ultimately stopped entirely, among women who discontinued contraception for method-related reasons. Results show that wanting to limit births, having ever been married, and recent prior use are all associated with switching versus stopping. In addition, we find that women in West and Middle Africa were more likely to stop use compared to women in other regions. Addressing obstacles to contraceptive continuation, including effective method switching, among women who wish to delay or avoid pregnancy should be a priority for global and country initiatives aiming to deliver client-centered care that supports women and couples to make their best family planning choices.

Contraceptive Method Information and Method Switching in India

The stagnation in the unmet need for family planning and rise in contraceptive discontinuation rates are major concerns among researchers and policymakers in India. This study attempts to investigate the association between method information received by the users at the time of initiation and the switching of contraceptive methods in India. Using the fourth round of National Family Health Survey (NFHS) data (2015–2016), a multinomial logistic regression model has been applied to assess the net effects of method information received by the users on switching of contraceptive methods. The reuse of contraceptive methods is higher among those who were not provided any method information. The reuse is also higher among those who were informed only about the side effects. Overall, the users who received comprehensive method information are more likely to switch. Particularly, the users who were informed about how to manage side effects either alone or along with other method information have a higher likelihood of switching especially to long-acting reversible contraceptives (LARC). The findings call for program intervention to provide comprehensive method information to the users because it gives them the freedom to switch to more suitable methods. Thus, it would help in achieving the sustainable development goal (3.7) of informed choice of contraceptive methods.

\u201cYou better use the safer one\u2026 leave this one\u201d: the role of health providers in women\u2019s pursuit of their preferred family planning methods

BackgroundUniversal access to quality sexual and reproductive health (SRH) services is pivotal to ensuring gender equality. In high-income countries, patient-provider interactions have been shown to shape women’s decisions about contraception, with poor exchanges decreasing method uptake and satisfaction. While significant progress has been made to increase women’s access to SRH services, in low- and middle-income countries, little is known about the quality of family planning patient-provider interactions. The primary objective of this analysis was to explore the role of health care providers in women’s family planning decision-making in Ethiopia.MethodsFrom July to August 2017, 10 focus group discussions (n = 80) and 30 in-depth interviews were conducted with women aged 15–49 and men aged 18+ recruited via purposive sampling from urban and rural sites in Ethiopia. Semi-structured interview guides explored women’s and girls’ empowerment in SRH surrounding sex, childbearing, and contraception. All interviews were conducted in Amharic, audio-recorded, and transcribed verbatim into English. Inductive thematic analysis was used to analyze data. Eleven codes specific to provider services for family planning were reviewed and matrixes creates for synthesis.ResultsThree primary themes emerged: the role of providers in women’s awareness of and demand for family planning services; selection and uptake of contraceptive methods; and discontinuation and switching of contraceptive methods. Results indicate that health extension workers were central to women’s awareness of family planning, and health providers’ endorsements were instrumental in decisions to adopt methods. The majority of respondents described positive interactions with providers and appreciated thorough counseling when considering using or switching methods. Some women, however, described health providers directing them toward long-acting methods by communicating inaccurate information or emphasizing disadvantages of short-acting methods. A few women described provider reluctance or resistance to switching methods, especially from implants.ConclusionsWomen shared many narratives about the central roles health providers played in their awareness and decision-making for family planning. Those narratives also included provider bias against women’s preferred methods. Further research and program assessments are needed to ascertain the extent to which these biases hinder women’s decision-making autonomy in using contraception.

Perceptions of Contraception and Patterns of Switching Contraceptive Methods Among Family-planning Acceptors in West Nusa Tenggara, Indonesia.

ObjectivesThe perceptions of family-planning (FP) acceptors regarding contraception influence the reasons for which they choose to switch their method of contraception. The objective of this study was to analyze the perceptions of contraception and rationales for switching contraceptive methods among female FP acceptors in West Nusa Tenggara, Indonesia.MethodsThis study involved the analysis of secondary data from the Improve Contraceptive Method Mix study, which was conducted in 2013 by the Center for Health Research, University of Indonesia. The design of the study was cross-sectional. We performed 3 stages of sampling using the cluster technique and selected 4819 women who were FP acceptors in West Nusa Tenggara Province, Indonesia as the subjects of this study. The data were analyzed using multiple logistic regression.ResultsThe predominant pattern of switching contraceptive methods was switching from one non-long-term method of contraception to another. Only 31.0% of the acceptors reported a rational pattern of switching contraceptive methods given their age, number of children, and FP motivations. Perceptions of the side effects of contraceptive methods, the ease of contraceptive use, and the cost of the contraceptives were significantly associated (at the level of α=0.05) with rational patterns of switching contraceptive methods.ConclusionsPerceptions among FP-accepting women were found to play an important role in their patterns of switching contraceptive methods. Hence, fostering a better understanding of contraception through high-quality counseling is needed to improve perceptions and thereby to encourage rational, effective, and efficient contraceptive use.

Contraceptive method switching among women living in sub-Saharan Africa participating in an HIV-1 prevention trial: a prospective cohort study

ObjectiveLong-acting reversible contraceptive (LARC) method uptake has been low within the context of HIV prevention trials. Within a multinational study (MTN-020/ASPIRE), the Contraceptive Action Team improved LARC accessibility and uptake. In this secondary analysis, we determined the rate of contraceptive method continuation among the women enrolled. Study designASPIRE was a randomized, double-blinded, placebo-controlled phase III safety and effectiveness study of the Dapivirine Vaginal Ring for HIV-1 prevention. Between 2012 and 2014, sexually active women aged 18–45 from Malawi, South Africa, Uganda and Zimbabwe were enrolled. All participants were required to use contraception for enrollment to the study and could choose between all highly effective contraceptive methods available in their respective countries. Women were seen monthly and could change methods at any time. Continuation rates from study enrollment to 6 and 12 months were determined. ResultsThe overall contraceptive method continuation rate was 77% (1972/2551) at 6 months and 66% (1694/2551) at 12 months. The 6- and 12-month continuation rates were highest for implantable contraceptives (89%, 82%) followed by copper intrauterine device (83%, 77%). Rates of continuation for injectable contraceptives depot medroxyprogesterone acetate (80%, 69%) and norethisterone enanthate (71%, 54%) were higher than for oral contraceptives, which were continued at 47% at 6 months and 35% at 12 months. The continuation rates of all methods did not differ by users with and without previous contraceptive experience. ConclusionsLARC methods have the highest rates of continuation at 12 months and should be routinely offered in the context of HIV prevention trials in sub-Saharan Africa. ImplicationsIntrauterine devices and contraceptive implant continuation was high at 12 months among women participating in an HIV prevention trial in sub-Saharan Africa and LARCs and should be routinely offered.

Predictors of contraceptive switching and discontinuation within the first 6 months of use among Highly Effective Reversible Contraceptive Initiative Salt Lake study participants

Nearly half of women will switch or discontinue using their selected contraceptive method in the first year. Research on early switching or discontinuation provides important clinical and public health insights, although few studies have assessed associated factors, particularly among longitudinal cohorts. The current study explores attributes associated with early contraceptive method switching or discontinuation (<6 months of initiation) among participants enrolled in the intervention cohorts of the Highly Effective Reversible Contraceptive Initiative Salt Lake Contraceptive Initiative (Utah, United States). Highly Effective Reversible Contraceptive Initiative Salt Lake participants have access to no-cost contraception for 3 years. This includes both the initial selection and the ability to switch or to discontinue methods without cost. Methods available included the following: nonhormonal behavioral methods (male/female condoms, withdrawal, diaphragms, cervical caps, and fertility awareness); short-acting methods (pill, patch, ring, and injectable); and long-acting methods (intrauterine devices and contraceptive implants). Participants completed surveys at baseline and at 1, 3, and 6 months. We collected data on participant demographics, contraceptive continuation, switching, and discontinuation, as well as factors associated with these changes, including established measures of pregnancy intention and ambivalence and reasons for switching or discontinuing. We conducted descriptive statistics, univariable, and multivariable Poisson regression analyses to assess predictors of both discontinuation and switching. We also conducted χ2 analyses to compare reported reasons for stopping between switchers and discontinuers. At 6 months, 2,583 women (70.0%) reported continuation of their baseline method, 367 (10%) reported at least 1 period of discontinuation, 459 (12.4%) reported switching to a different method, and 279 (7.6%) did not provide 6-month follow-up. Factors associated with discontinuation included selection of a short-acting method (incidence rate ratio [IRR], 2.49; 95% confidence interval [CI], 1.97, 3.12), report of Hispanic ethnicity (IRR, 1.45; 95% CI, 1.12, 1.89) and nonwhite race (IRR, 1.48; 95% CI, 1.08, 2.02), and having any future pregnancy plans, even years out. Participants with some college education were less likely to report discontinuation (IRR, 0.73; 95% CI, 0.57, 0.94). Selecting a short-acting method at baseline was also associated with increased likelihood of method switching (IRR, 2.29, 95% CI, 1.87, 2.80), as was having 2 or more children (IRR, 1.37; 95% CI, 1.08, 1.74). Women were less likely to switch if they were on their parents' insurance (IRR, 0.74; 95% CI, 0.56, 0.99). Among participants who switched methods, 36.9% switched to a long-acting reversible method, 31.7% switched to a short-acting hormonal method, and 31.1% switched to a nonhormonal behavioral method, such as condom use. Of participants providing a reason for stopping, 454 women (73.2%) reported side effects as 1 reason for switching or discontinuing their initial method. Early contraceptive method switching and discontinuation are frequent outcomes of contraceptive use. These changes are common even with removal of contraceptive access barriers.

Predictors of contraceptive method switching and discontinuation 6-months postabortion

Objectives: Gaps in contraceptive coverage increase the risk of unintended pregnancy. We identify the predictors of switching and discontinuation of postabortion contraception at 6 months postabortion.

Use and discontinuation of intrauterine contraceptive device in the Greater Accra Region of Ghana

BackgroundThe intrauterine contraceptive device is one of the modern long-acting and reversible contraception that is very safe and effective. Yet, less than 2 % of women are using intrauterine devices in Ghana. This study therefore explored the experiences and barriers to intrauterine contraceptive device use and discontinuation in Greater Accra Region, Ghana.MethodsIntrauterine contraceptive device users and providers were purposively selected from eight private family planning clinics in the Greater Accra Region. Semi-structured interview guides were used for in-depth interviews during data collection. The interviews were audio-taped to ascertain accurate accounts of the interviews and recordings replayed for analytical responses. Field assistants transcribed the interviews conducted themselves and read through the transcripts produced twice to increase familiarity with the dataset. A list of code labels was created and a series of categories for the main themes that emerged from the transcripts were developed. The transcribed data was organized, coded and manually thematically analysed in word. Study results were presented in tables and quotes from respondents.ResultsResults showed that key motivations for intrauterine contraceptive device use include effectiveness, benefits, and efficacy of the device, fertility regulation, peace of mind, contraceptive method switching, health provider effects, desire for long-acting contraceptive method, and partner characteristics. Intrauterine contraceptive device discontinuation was due to bleeding irregularities, vaginal infections, desire to increase fertility, physical features of the intrauterine device, and partner disapproval of use. Other reasons in both cases pertained to non-hormonal aspects of the intrauterine device, partner characteristics, and provider encouragement and influence.ConclusionsSeveral factors influence the use and discontinuation of intrauterine device in Ghana. Comprehensive contraceptive counselling on the intrauterine device is essential in promoting uptake and knowledge of the intrauterine device at the health facility level. Various targeted messages are also needed to dispel misconceptions at the community level.

Using automated voice messages linked to telephone counselling to increase post-menstrual regulation contraceptive uptake and continuation in Bangladesh: study protocol for a randomised controlled trial

BackgroundAdoption of modern contraceptive methods after menstrual regulation (MR) is thought to reduce subsequent unwanted pregnancy and abortion. Long-acting reversible contraceptives (LARCs) are highly effective at reducing unintended pregnancy, but uptake in Bangladesh is low. Providing information on the most effective methods of contraception increases uptake of more effective methods. This protocol describes a randomised controlled trial of an intervention delivered by mobile phone designed to support post-MR contraceptive use in Bangladesh.MethodsThis is a multi-site single blind individual randomised controlled trial. At least 960 women undergoing MR procedures at selected facilities will be recruited after their procedure by female research assistants. Women will be randomised into the control or intervention group with a 1:1 ratio.All participants will receive usual clinic care, including contraceptive counselling and the telephone number of a non-toll-free call centre which provides counselling on MR and contraception. During the 4 months after their MR procedure, intervention participants will be sent 11 recorded interactive voice messages to their mobile phone about contraception with a focus on their chosen method and LARCs. Each message allows the participant to connect directly to the call centre. The intervention is free to the user. The control group will receive no messages delivered by mobile phone. All participants will be asked to complete an in-person questionnaire at recruitment and follow-up questionnaires by telephone at 2 weeks, 4 months and 12 months after their MR. The primary outcome for the trial will be self-reported LARC use 4 months post-MR. Secondary outcomes include LARC use at 2 weeks and 12 months post-MR, use of any effective modern contraceptive method at 2 weeks, 4 months and 12 months post-MR, and contraceptive discontinuation, contraceptive method switching, pregnancy, subsequent MR and experience of violence during the 12 month study period.DiscussionMobile phones offer a low-cost mechanism for providing individualised support to women with contraception outside of the clinic setting. This study will provide information on the effects of such an intervention among MR clients in Bangladesh.Trial registrationTrial registered with clinicaltrials.gov Registration number: NCT02579785 Date of registration: 16th October 2015.

Twelve-month contraceptive continuation among women initiating short- and long-acting reversible contraceptives in North Kivu, Democratic Republic of the Congo.

ContextDespite the inclusion of sexual and reproductive health (SRH) services in the minimum standards of health care in humanitarian settings, access to SRH services, and especially to contraception, is often compromised in war. Very little is known about continuation and switching of contraceptive methods in these settings. An evaluation of a contraceptive services program in North Kivu, Democratic Republic of the Congo (DRC) was conducted to measure 12-month contraceptive continuation by type of contraceptive method (short-acting or long-acting).MethodsA stratified systematic sample of women who initiated a contraceptive method 12–18 months prior to data collection was selected retrospectively from facility registers. A total of 548 women was interviewed about their contraceptive use: 304 who began a short-acting method (pills, injectables) and 244 who began a long-acting method (intra-uterine devices, implants). Key characteristics of short-acting method versus long-acting method acceptors were compared using chi-square statistics for categorical data and t-tests for continuous data. Unadjusted and adjusted Cox proportional hazard ratios were estimated to assess factors associated with discontinuation.ResultsAt 12 months, 81.6% women reported using their baseline contraceptive method continuously, with more long-acting than short-acting contraceptive acceptors (86.1% versus 78.0%, p = .02) continuing contraceptive use. Use of a short-acting method (Hazard ratio (HR) 1.74 [95%CI 1.13–2.67]) and desiring a child within two years (HR 2.58 [95%CI 1.45–4.54]) were associated with discontinuation within the first 12 months of use. The vast majority (88.3%) of women reported no prior contraceptive use.ConclusionThis is the first study of contraceptive continuation in a humanitarian setting. The high percentages of women continuing contraceptive use found here demonstrates that women will choose to initiate and continue use of their desired contraceptive method, even in a difficult, unstable and low contraceptive prevalence setting like North Kivu.

How long is long acting? Recent trends in mean duration of intrauterine device use

Objectives: Intrauterine device (IUD) use has increased fivefold since 2002, yet little is known about how women are using IUDs, including the typical duration of use. Methods: Drawing on 2006–2010 and 2011–2013 National Survey of Family Growth data, we calculated women’s mean completed duration of IUD use by survey wave, age group and method dissatisfaction. Results: The mean completed duration of IUD use declined from 47 months in 2006–2010 to 31 months in 2011–2013 (p<.05). Among women aged 25–44, mean use declined from 51 months in 2006–2010 to 34 months in 2011–2013 (p=.09). Among younger women (aged 15–24), mean use declined from 23 months in 2006–2010 to 13 months in 2011–2013 (p=.07). The proportion of women with a mean duration of use less than 12 months increased, from 24% in 2006–2010 to 36% in 2011–2013 (p=.08). Women who discontinued their IUD due to dissatisfaction had shorter mean periods of use: For example, 22 months versus 40 months among those who did not discontinue due to dissatisfaction in 2011–2013 (p<.05). Conclusions: As more women have chosen IUDs, mean duration of use has decreased. This may reflect more women “testing the waters” with IUDs, owing to increased insurance coverage and provider skills, targeted counseling, same-day insertion protocols and growing patient awareness; as well as a shift toward hormonal IUDs, with a shorter maximum duration of use. These results suggest the need for patient-centered counseling approaches and the mitigation of policy, payer and procedural barriers to facilitate desired and timely IUD removal and contraceptive method switching.

Prevalence and associated factors of contraceptive discontinuation and switching among Bangladeshi married women of reproductive age.

IntroductionContraceptive discontinuation is a worldwide incident that may be connected with low incentive to avoid pregnancy. Contraceptive discontinuation highly contributes to unplanned pregnancy and unwanted births.ObjectivesThe objective of this study was to observe the prevalence of discontinuation and switching of contraceptive methods among Bangladeshi married women. In addition, the sociodemographic factors associated with contraceptive discontinuation and switching were assessed.MethodsSecondary cross-sectional data was used in this study. A total of 16,273 married Bangladeshi women of reproductive age (15–49 years) were considered in the present study, from the Bangladesh Demographic and Health Survey, 2011. Logistic regression models were used to determine the relationships between key sociodemographic factors and user status.ResultsThe prevalence of discontinuation and switching of contraceptive method among women were 38.4% and 15.4%, respectively. The logistic regression model demonstrated that women in early reproductive years (25–29 years and 30–34 years) significantly more often (odds ratio [OR] =0.84 and 0.71, respectively) discontinued use of contraceptives. Significantly higher rates of discontinuation were pronounced among women who used the pill (OR =0.72) and injectable contraception users (OR =0.60), had small family size (OR =0.49), lived in a rural community (OR =1.65), and who were less educated (OR =1.55).ConclusionContraceptive discontinuation may reflect an association among less education, currently married, and smaller family size. Awareness of contraceptive methods can decrease the burden of unplanned pregnancies and thus progresses the family planning program.

Stopping and switching contraceptive methods: findings from Contessa, a prospective longitudinal study of women of reproductive age in England

BackgroundDiscontinuation of, and change in, use of contraceptive methods contributes to high unplanned pregnancy rates. The aims of the Contessa study were to estimate the prevalence of and reasons for discontinuation and change and to assess the implications for preventive intervention. MethodsProspective cohort study of 1091 potentially fertile women aged 18–49, carried out during 2008, using a sample drawn from the Health Survey for England 2006, a random probability survey of health. We carried out a baseline survey followed by three further waves, exploring patterns of contraceptive use, characteristics of women experiencing each, and reasons for discontinuation and change. FindingsA percentage of 3.7 of women were at risk of unplanned pregnancy and discontinued and/or changed a contraceptive method in a year, compared with 4.7% who were at risk of unplanned pregnancy and used no method. Compared with continuous users, stoppers and switchers were younger, better educated and more likely to be single. Women discontinued or changed their contraceptive method for reasons of ease of use, reliability, side effects or concerns over health effects. Barely a quarter of such decisions were influenced by medical staff. InterpretationEffective strategies to aid contraceptive adherence have proved elusive but, if found, could reduce unplanned pregnancy rates appreciably. Understanding of the factors contributing to successful contraceptive practice is essential to prevention of unintended pregnancy.

Does switching contraceptive from oral to a patch or vaginal ring change the likelihood of timely prescription refill?

ObjectiveThis study evaluated contraceptive refill patterns of women insured commercially in the US who switched from oral contraceptives (OCs) to the patch or vaginal ring and assessed if switching contraceptive methods changes refill patterns. Study DesignWomen aged 15–44 with ≥2 patch or ring prescriptions and ≥2 OC prescriptions before the first patch/ring prescription were identified from the MarketScan® Commercial database (1/1/2002-6/30/2011). Refill patterns 1-year pre- and postindex date (first patch/ring prescription) were evaluated, and women were categorized as timely or delayed refillers on OCs and patch/ring. Regression modeling was used to investigate the association between refill patterns and contraceptive methods and switching effects on refill patterns. ResultsOf 17,814 women identified, 7901 switched to the patch, and 9913 switched to the ring. Among timely OC refillers, the percentage of timely refills decreased (patch: 95.6% to 79.4%, p<.001; ring: 96.5% to 74.3%, p<.001). However, among delayed OC refillers, the percentage of timely refills improved (patch: 47.9% to 72.2%, p<.001; ring: 50.4% to 64.0%, p<.001) during patch/ring use. Nonetheless, compared to timely OC refillers, women who were delayed OC refillers had 1.68-fold [95% confidence interval (CI): 1.52–1.84, p<.001] and 1.85-fold greater odds (CI: 1.69–2.02, p<.001) of being a delayed refiller while on the patch and ring, respectively. ConclusionSwitching to the patch or ring may improve refill behavior for women who have problems refilling OCs timely; however, the magnitude of the improvement may fail to improve ultimate contraceptive efficacy by simply switching to the patch or ring. ImplicationsThe impact on timely refills of switching from OCs to either the patch or ring is complex and varies depending on the pattern of timely refills on OCs.

Awareness and Interest in Intrauterine Contraceptive Device Use among HIV-Positive Women in Cape Town, South Africa

Objective. To assess awareness of and interest in intrauterine contraceptive device (IUCD) use among HIV-positive women in Cape Town, South Africa. Design. Cross-sectional survey. Methods. HIV-positive women aged 18 through 45 years presenting for care at a primary health care clinic in Cape Town, South Africa participated in this study. Consented participants completed a staff-administered questionnaire in a private setting. Descriptive statistics were generated. Comparisons between demographic and reproductive health-related variables and IUCD awareness and interest were performed with multiple logistic regression. Analyses for IUCD interest excluded women with prior surgical sterilization. Results. Of 277 HIV-positive women, 37% were aware of the IUCD; awareness was independently associated with greater age (adjusted odds ratio (AOR) = 1.15, 95%; confidence interval (CI): 1.10–1.20) and not switching contraceptive methods in the last year (AOR = 2.45, 95% CI: 1.03–5.83). Following an IUCD information session, 86% of women (n = 206/240) were interested in IUCD use. IUCD interest was inversely associated with age (AOR = 0.91, 95% CI: 0.86–0.97) and marginally positively associated with current menstrual bleeding pattern complaints (AOR = 2.14, 95% CI: 0.98–4.68). Conclusions. Despite low levels of method awareness, HIV-positive women in this setting are frequently interested in IUCD use, indicating need for programming to expand method access.

Contraceptive Method Switching in the United States

Switching among contraceptive method types is the primary determinant of the prevalence of use of specific contraceptive methods, and it has direct implications for women's ability to avoid unintended pregnancies. Yet, method switching among U.S. women has received little attention from researchers. Data from the 1995 National Survey of Family Growth were used to construct multiple-decrement life tables to explore the gross switching rates of married and unmarried women. Within each group, discrete-time hazard models were estimated to determine how women's characteristics affect their switching behavior. Overall rates of method switching are high among both married and unmarried women (40% and 61%, respectively). Married women's two-year switching rates vary from 30% among women who use the implant, injectable, IUD or other reversible methods to 43% among nonusers, while unmarried women's rates vary from 33% among women who use the implant, injectable or IUD to 70% among nonusers. Multivariate analyses of method switching according to women's characteristics indicate that among married women, women without children are less likely than other women to adopt sterilization or a long-term reversible contraceptive (the implant, injectable or IUD). Older married women have a higher rate than their younger counterparts of switching to sterilization, but are also more likely to continue using no method. Among unmarried women, younger and more highly educated women have high rates of switching to the condom and to dual methods. Women's method switching decisions may be driven primarily by concerns related to level and duration of contraceptive effectiveness, health risks associated with contraceptive use and, among single women, sexually transmitted disease prevention.
