Randomized clinical trial of self versus clinical administration of subcutaneous depot medroxyprogesterone acetate

Digital training for self-injectable contraceptives: a feasibility and acceptability pilot study

BACKGROUND

Self-injectable contraceptives, namely subcutaneous depot medroxyprogesterone acetate 104 mg micronised formulation delivered via uniject system, reduce the need to travel to a facility for contraceptive access, but the initial, in-person, training may be a barrier to starting this method. This article reports on a small, exploratory pilot in Kenya to test the feasibility and acceptability of digital self-injection training.

METHODS

Participants (n=11) who were currently using injectable contraceptives, intramuscular depot medroxyprogesterone acetate 150 mg injected by a healthcare worker, received digital self-injection training from a trained clinician via a WhatsApp video call. Participants administered a simulated self-injection on a model and an actual self-injection (under supervision) on themselves. The participants' self-injection proficiency, a measure of the feasibility of remote training, was documented using a checklist, and participants were administered a questionnaire about their training experience. The training was observed, and content analysis was used to understand the functionality of training.

RESULTS

All participants were proficient when performing the self-injection on themselves after receiving the remote training and reported that the training was acceptable. A barrier to training via a video call was lack of access to quality digital devices. Eight training 'lessons learnt' emerged from the training observations.

CONCLUSIONS

Training participants to administer self-injectable contraceptives via WhatsApp video call was feasible and acceptable. Training lessons learnt offer pragmatic adaptations for communicating about a practical skill via a digital channel. Further research is needed to ascertain the efficacy of digital training for self-injection and feasibility and acceptability for wider groups.

Patient experiences switching from in-clinic to self-administration of injectable contraception in two Western US states

OBJECTIVE

We describe the experiences and preferences of women who switched from clinic-administered intramuscular depot medroxyprogesterone acetate (DMPA-IM) to self-administered subcutaneous DMPA (DMPA-SC) in the context of the COVID-19 pandemic.

METHODS

We conducted interviews with women in California and Washington about their experiences with self-administered DMPA-SC. We interviewed women after their first or second self-administered DMPA-SC injection and conducted follow-up interviews after their third or fourth injection. We performed both thematic and descriptive content analyses.

RESULTS

We completed 29 interviews with 15 women. Most participants (n = 10) were between the ages of 20 and 39 and the majority (n = 12) used DMPA primarily for contraception. Most (n = 13) described self-administered DMPA-SC as "very easy" or "somewhat easy" to use and reported greater convenience, decreased pain, fewer logistical and financial challenges, increased privacy, and improved comfort with injection compared to DMPA-IM. Participants identified difficulties obtaining DMPA-SC from pharmacies and safe needle disposal as barriers. Most (n = 13) would recommend DMPA-SC to a friend and desired to continue self-administration beyond the COVID-19 pandemic. Participants recommended counseling all patients about this option alongside other contraceptive methods, and offering clinician supervision, if desired.

CONCLUSION

Women who switched from in-clinic DMPA-IM to self-administered DMPA-SC during the COVID-19 pandemic preferred the latter and intended to continue self-administration. Self-administration of DMPA-SC should be routinely offered and easily accessible to patients.

Depot medroxyprogesterone acetate concentrations in patients with and without the use of antiseizure medications

OBJECTIVES

To measure plasma concentrations of medroxyprogesterone acetate (MPA) in users with epilepsy treated with antiseizure medications and compare these to MPA concentrations in those without epilepsy.

STUDY DESIGN

For this multisite cross-sectional study, we obtained a single blood sample from those with epilepsy treated with various antiseizure medications (n = 18) within the week before their next depot medroxyprogesterone injection. Among the participants without epilepsy (n = 20), 10 similarly were scheduled within the week prior to the next injection, and 10 were scheduled at earlier intervals to attempt to balance the time intervals between groups. MPA concentrations were determined by a validated assay.

RESULTS

MPA concentrations were similar among those with epilepsy and controls and between groups with and without the use of enzyme-inducing medications. The lowest MPA concentrations, under 0.07 ng/mL, were observed among two of eight using enzyme-inducing antiseizure medications, one of 10 using noninducing medications, and one of 19 controls had concentrations below 0.2 ng/mL.

CONCLUSIONS

In this exploratory study, lower MPA concentrations in some participants using enzyme-inducing antiseizure medications suggest a potential interaction that could reduce depot medroxyprogesterone efficacy.

Digital support for first time self-injectable contraceptive users in Nairobi, Kenya: A design evaluation

BACKGROUND

Women in Kenya have an unmet need for contraception, and self-injectable contraceptives offer a new, self-managed fertility control option. Self-injection reduces the need to travel to a facility for ongoing care, but the initial, in-person, consultation may be a barrier. Training in self-injection administration could be delivered via WhatsApp on a mobile phone.

METHODS

This study aimed to observe and document the design process of a WhatsApp delivered self-injectable contraceptive service. This design evaluation employs a mixed methods approach using; observation of design meetings, analysis of design documents (process maps, prototypes) and interviews with the design team. Participants who tested the remote training element of the final service design were interviewed about their experiences.

RESULTS

Four tasks, delivered by the digital service, were explored in further detail: provide information on self-injectables; ensure the technical and privacy requirements of the video call are met; obtain information from the user to check eligibility; and observe the users first self-injection. The challenges, assumptions, iterations, and learning associated with these key tasks were documented and 3 case studies emerged. These case studies explore how the digital service altered the timing and medium of a clinical interaction, the construction of the user's physical space when interacting with the service and the challenge of performing legitimacy via WhatsApp.

CONCLUSION

By examining self-care facilitated by digital technologies, there are opportunities to learn about self-care, digital care and face-to-face care. Through examining the design process, we discovered ways in which digital services can change the rhythm of health care interactions, namely by stretching the time, space and medium of clinical interaction. When interactions are altered in this way, clinical legitimacy must be negotiated in new ways.

Getting Up to Date with What Works: A Systematic Review on the Effectiveness and Safety of Task Sharing of Modern Methods in Family Planning Services

Objective

This systematic review was conducted to provide up-to-date evidence on the safety and effectiveness of task sharing in the delivery of modern contraceptives. Study Design. The review followed the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines. We searched Medline, Embase, Cochrane CENTRAL, and Google Scholar for peer-reviewed studies that reported on effectiveness and/or safety outcomes of task sharing of any modern contraceptive method. Only Cochrane Effective Practice of Organizations of Care (EPOC) study designs were eligible, and quality assessment of the evidence was performed using the Cochrane risk of bias (RoB) tools. Meta-analyses, where possible, were carried out using Stata, and certainty of the evidence for outcomes was assessed using the Grading of Recommendations Assessment, Development, and Evaluation tool (GRADE).

Results

Six studies met the inclusion criteria: five reported on self-injection of subcutaneous depot medroxyprogesterone acetate (DMPA-SC) compared to administered by trained health providers; and one assessed tubal ligation performed by associate clinicians compared to advanced-level associate clinicians. Self-injection improved contraceptive continuation, with no increase in unintended pregnancy and no difference in side effects compared to provider administered. In tubal ligation, the rate of adverse events, time to complete procedure, and participant satisfaction were similar among associate clinicians and advanced clinicians.

Conclusion

The evidence suggests that self-injection of DMPA-SC and tubal ligation performed by associate clinicians are safe and effective. These findings should be complemented with the evidence on the feasibility and acceptability of task sharing of these methods. The review protocol was registered with PROSPERO CRD42021283336.

Variability and quantification of serum medroxyprogesterone acetate levels

Quantification of serum progestin levels in clinical contraceptive studies is now routinely performed to understand progestin pharmacokinetics and to correct for unreliable self-reporting of contraceptive use by study participants. Many such studies are focussed on the three-monthly progestin-only intramuscular (IM) injectable contraceptive depot medroxyprogesterone acetate (DMPA-IM). Methods commonly used to measure serum MPA levels include liquid chromatography coupled to mass spectrometry (LC/MS) and radioimmunoassay (RIA); however, RIA methods have not been used in recent years. We review the available literature and find that these methods vary widely in terms of use of organic solvent extraction, use of derivitization and choice of organic solvent and chromatography columns. There is a lack of standardization of LC/MS methodology, including a lack of detailed extraction protocols. Limited evidence suggests that RIA, without organic solvent extraction, likely over-estimates progestin levels. Maximum MPA concentrations in the first two weeks post-injection show wide inter-individual and inter-study variation, regardless of quantification method used. Standardization of quantification methods and sampling time post-injection is required to improve interpretation of clinical data, in particular the side effects arising at different times depending on the pharmacokinetic profile unique to injectable contraceptives.

Society of Family Planning clinical consensus on self-administration of subcutaneous depot medroxyprogesterone acetate (DMPA-SC)

Depot medroxyprogesterone acetate (DMPA) is a highly-effective, injectable contraceptive method that requires injections every 12 to 15 weeks. The need for return visits to a healthcare provider may present barriers to access, use, and continuation of DMPA. Studies demonstrate that self-administration of subcutaneous DMPA (DMPA-SC) outside clinical settings is safe, effective, feasible, acceptable, and can improve continuation. Based on existing evidence and potential to improve contraceptive access and autonomy, the Society of Family Planning recommends that DMPA-SC self-administration be made widely available as an additional option for patients. Provider-administered DMPA must also remain available to meet patients' individual needs and preferences.

Self-administered subcutaneous medroxyprogesterone acetate for improving contraceptive outcomes: a systematic review and meta-analysis

BACKGROUND

Subcutaneous depot medroxyprogesterone acetate is an easy-to-use injectable contraceptive. A trained person can administer it, including women through self-injection. The objective of this systematic review and meta-analysis was to assess the effectiveness and safety of self-injection versus provider-administered subcutaneous depot medroxyprogesterone acetate for improving continuation of contraceptive use.

METHODS

We searched for randomized controlled trials on November 1, 2020 in Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, Embase, Web of Science, Scopus, Open Grey, clinical trials registries, and reference lists of relevant studies. We did not impose any search restrictions. We included randomized trials comparing self- versus provider-administered subcutaneous depot medroxyprogesterone acetate. Two authors independently screened trials, extracted data, and assessed the risk of bias in the included studies. We used risk ratio and 95% confidence intervals for dichotomous outcomes.

RESULTS

We identified 3 randomized trials (9 reports; 1264 participants). The risk of bias in the included studies was low except for performance bias and detection bias of participant-reported outcomes in unmasked trials. Self-administration, compared to provider-administration, increased continuation of contraceptive use (risk ratio 1.35; 95% confidence intervals 1.10-1.66); moderate-certainty evidence). Self-injection appears to be making more of an impact on continuation for younger women compared to women 25 years and older and on women living in low and middle income compared to high income countries. There was no subgroup difference by the type of care provider (community health worker vs. clinic-based provider).

CONCLUSIONS

Self-injection of subcutaneous depot medroxyprogesterone acetate probably improves continuation of contraceptive use. The effects on other outcomes remain uncertain because of the very low certainty of evidence.

Update to U.S. Selected Practice Recommendations for Contraceptive Use: Self-Administration of Subcutaneous Depot Medroxyprogesterone Acetate

U.S. Selected Practice Recommendations for Contraceptive Use (U.S. SPR), adapted by CDC from global guidance developed by the World Health Organization (WHO), provides evidence-based guidance on contraceptive use for U.S. health care providers (1). During January-February, 2021, CDC evaluated the 2019 WHO recommendation on self-administered subcutaneous depot medroxyprogesterone acetate (DMPA-SC) (2). CDC adopted the WHO recommendation on the basis of moderate-certainty evidence that self-administered DMPA-SC is safe and effective, and has higher continuation rates compared with provider-administered DMPA. The new U.S. SPR recommendation states that self-administered DMPA-SC should be made available as an additional approach to deliver injectable contraception. Provider-administered DMPA should remain available. Self-administered DMPA-SC is a user-controlled method that has the potential to improve contraceptive access and increase reproductive autonomy. Self-administered DMPA-SC should be offered in a noncoercive manner through a shared decision-making process between patients and their health care providers, with a focus on patient preferences and equitable access to the full range of contraceptive methods.

Characteristics associated with use of subcutaneous depot medroxyprogesterone acetate (DMPA-SC) in Burkina Faso, Democratic Republic of Congo, and Uganda

Objectives

To what extent is DMPA-SC reaching new users versus encouraging method switching among existing users? Though increasingly-popular, little is known about characteristics of women using DMPA-SC in SSA. We compared characteristics of women using DMPA-SC with those of other modern methods, and identified the extent to which women using DMPA-SC switched from another method or are first-time users of contraception.

Study design

We used data collected by the Performance Monitoring for Action (PMA) Project between 2016 and 2019 from three countries, Burkina Faso, Democratic Republic of Congo, and Uganda. We tabulated characteristics of DMPA-SC, DMPA-IM, implant, and male condom users, and used multivariate analysis to compare characteristics of women using DMPA-SC those of the other three methods. We also examined previous contraceptive method use (if any) among women currently using DMPA-SC.

Results

We found that never-married women were more likely to use male condoms instead of DMPA-SC. Women with two or more children (compared to no children or one child) were more likely to use implants instead of DMPA-SC in both Uganda and DRC. DMPA-SC was the first method used by the majority of current users in Burkina Faso and Uganda. DMPA-SC users who previously used another method generally switched from less effective methods.

Conclusions

Although the characteristics of women using DMPA-SC varied across countries, DMPA-SC appears to be reaching new populations of women instead of inspiring existing modern users to switch to DMPA-SC, and appears to be appealing to first time users of contraception.

Implications

It appears that DMPA-SC appeals to new contraceptive users in sub-Saharan Africa, which implies that DMPA-SC may have the potential to increase modern contraceptive prevalence in sub-Saharan African countries.

Evidence-Based Guidance for Self-Administration of Injectable Contraception

The requirement of in-person visits every 3 months for a health care provider to administer intramuscular depot medroxyprogesterone acetate (DMPA-IM) is a significant barrier to its use, particularly in the wake of the coronavirus pandemic. Time and travel costs as well as scheduling conflicts also negatively impact the receipt of subsequent contraceptive injections, which can result in unintended pregnancies. Subcutaneous depot medroxyprogesterone acetate (DMPA-SC) can be self-administered by individuals at home, expanding contraceptive access, convenience, and reproductive autonomy. With 30% less progestin, DMPA-SC improves upon the DMPA-IM formulation while retaining efficacy. As part of comprehensive contraceptive counseling, health care providers should consider offering DMPA-SC to eligible individuals interested in self-administration. Using a case study approach, evidence-based recommendations are reviewed for the off-label use of self-administered DMPA-SC in the United States.

Clinically established biodegradable long acting injectables: An industry perspective

Long acting injectable formulations have been developed to sustain the action of drugs in the body over desired periods of time. These delivery platforms have been utilized for both systemic and local drug delivery applications. This review gives an overview of long acting injectable systems that are currently in clinical use. These products are categorized in three different groups: biodegradable polymeric systems, including microparticles and implants; micro and nanocrystal suspensions and oil-based formulations. Furthermore, the applications of these drug delivery platforms for the management of various chronic diseases are summarized. Finally, this review addresses industrial challenges regarding the development of long acting injectable formulations.

Self-care provision of contraception: Evidence and insights from contraceptive injectable self-administration

As new reproductive health products become available, women increasingly want to take a participatory role in their health. New developments and formulations of contraceptive products provide an opportunity to support this evolving trend toward self-care. Self-care, as defined by the World Health Organization (WHO), highlights the ability of individuals to promote health, prevent disease, and manage their own health with or without the support of a health care provider. The recently released WHO Guidelines on Self-Care Interventions for Health: Sexual and Reproductive Health and Rights included new self-care recommendations related to use of family planning, including self-injection of injectable contraceptives and over-the-counter provision of oral contraceptive pills. This paper focuses on the research evidence of self-administration (self-injection) of subcutaneous depot medroxyprogesterone acetate (DMPA-SC), and the practical experience of providers, women, and family planning programs adopting self-injection practices. We also explore the role of self-care in the provision of other contraceptives.

Trends in subcutaneous depot medroxyprogesterone acetate (DMPA-SC) use in Burkina Faso, the Democratic Republic of Congo and Uganda

Objectives

Subcutaneous depot medroxyprogesterone acetate (DMPA-SC) is seen as a valuable innovation in family planning, but little is known about trends in DMPA-SC use or characteristics of users. Using data from Burkina Faso, the Democratic Republic of Congo (DRC) and Uganda, we measured trends in DMPA-SC and identified characteristics associated with DMPA-SC use.

Study design

We used repeated cross-sectional representative data collected between 2016 and 2019. First, we plotted trends in DMPA-SC use for all women and married women. Next, we presented the sociodemographic and family-planning-related characteristics of DMPA-SC users. Finally, we conducted weighted multivariate logistic regression analysis to examine how DMPA-SC users were different from women (1) using all other modern methods combined and (2) not using any modern method.

Results

DMPA-SC use increased monotonically in all three countries. Many DMPA-SC users were first-time users of modern contraception (54.5% in Burkina Faso, 34.6% in DRC, 50.7% in Uganda). Never-married women had lower odds than married women of using DMPA-SC (compared to other modern methods) in all three countries [Burkina Faso adjusted odds ratio (AOR) 0.40, 95% confidence interval (95% CI) 0.20–0.80; DRC AOR 0.31 95% CI 0.10–0.93; Uganda AOR 0.24; 95% CI 0.08–0.71]. Level of education was positively associated with DMPA-SC use (compared to no use) (Burkina Faso AOR 1.79; 95% CI 1.03–3.14; Uganda AOR 3.23; 95% CI 1.33–7.84).

Conclusions

DMPA-SC is a rapidly growing method in these settings. Despite the comparable levels of and increases in use for all three countries, the characteristics associated with DMPA-SC use generally differed across countries.

Implications

This is the first analysis of patterns of DMPA-SC use with representative data for African countries. Our results confirm that DMPA-SC is increasingly popular, although the profile of users varies across settings.

Assessment of Self-Administration of Romiplostim in Patients with Immune Thrombocytopenic Purpura after Receipt of Home Administration Training Materials: a Cross-Sectional Study

Introduction

Romiplostim is a subcutaneously administered thrombopoietin-receptor agonist approved in the European Union for self-administration (or administration by a caregiver) in selected adult patients with chronic primary immune thrombocytopenia refractory to other treatments. To mitigate the risk of medication errors due to self-administration, the manufacturer has implemented additional risk minimisation measures (RMM) in the form of a Home Administration Training (HAT) pack to support the training of both healthcare professionals (HCPs) (guide and checklist for patient selection and training) and patients (a preparation mat, quick guide booklet, step-by-step guide, self-administration diary and DVD/video).

Objective

The primary objective was to estimate the proportion of patients/caregivers who administered romiplostim correctly after HAT pack training.

Methods

A multicentre observational study was conducted to evaluate the effectiveness of the HAT pack by recording data on a standardised collection form during direct observation of patients/caregivers in the act of administering romiplostim at the first standard-of-care visit 4 weeks after training with the HAT pack.

Results

Among the 40 patients/caregivers enrolled across 12 study centres in eight European countries, 35 [87.5%; 95% confidence interval (CI) 73.9–94.5] administered romiplostim correctly, and five (12.5%; 95% CI 5.5–26.1) did not.

Conclusion

The correct administration of romiplostim by most patients/caregivers supports the effectiveness of the HAT pack as an additional risk minimisation tool in the population and setting of this study.

What Is New in Contraception?: Best Articles From the Past Year

This month we focus on current research in contraception. Dr. Resnik discusses five recent publications, which are concluded with a "bottom-line" that is the take-home message. A complete reference for each can be found on on this page along with direct links to abstracts.

Self-administration of injectable contraception: a systematic review and meta-analysis

Introduction

Depot medroxyprogesterone acetate subcutaneous injectable contraception (DMPA-SC) may facilitate self-administration and expand contraceptive access. To inform WHO guidelines on self-care interventions, we conducted a systematic review and meta-analysis comparing self-administration versus provider administration of injectable contraception on outcomes of pregnancy, side effects/adverse events, contraceptive uptake, contraceptive continuation, self-efficacy/empowerment and social harms.

Methods

We searched PubMed, Cumulative Index to Nursing and Allied Health Literature, LILACS and EMBASE in September 2018 for peer-reviewed studies comparing women who received injectable contraception with the option of self-administration with women who received provider-administered injectable contraception on at least one outcome of interest. Risk of bias was assessed using the Cochrane tool for randomised controlled trials (RCTs) and the Evidence Project tool for non-randomised studies. Meta-analysis was conducted using random-effects models to generate pooled estimates of relative risk (RR).

Results

Six studies with 3851 total participants met the inclusion criteria: three RCTs and three controlled cohort studies. All studies examined self-injection of DMPA-SC; comparison groups were either provider-administered DMPA-SC or provider-administered intramuscular DMPA. All studies followed women through 12 months of contraceptive coverage and measured (dis)continuation of injectable contraception. Meta-analysis found higher rates of continuation with self-administration compared with provider administration in three RCTs (RR: 1.27, 95% CI 1.16 to 1.39) and three controlled cohort studies (RR: 1.18, 95% CI 1.10 to 1.26). Four studies reported pregnancies; all showed no difference across study arms. Four studies reported side effects/adverse events; while two controlled cohort studies showed increased injection site reactions with self-administration, no other side effects increased with self-administration. One study found no difference in social harms. No studies reported measuring uptake or self-efficacy/empowerment.

Conclusion

A growing evidence base suggests that self-administration of DMPA-SC can equal or improve contraceptive continuation rates compared with provider administration. This benefit comes without notable increases in pregnancy or safety concerns. Self-injection of DMPA-SC is a promising approach to increasing contraceptive use.

Cost-effectiveness of self-injected DMPA-SC compared with health-worker-injected DMPA-IM in Senegal

Objectives

To evaluate the cost-effectiveness of self-injected subcutaneous depot medroxyprogesterone acetate (DMPA-SC) compared to health-worker-administered intramuscular DMPA (DMPA-IM) in Senegal and to assess how including practice or demonstration injections in client self-injection training affects estimates.

Study design

We developed a decision-tree model with a 12-month time horizon for a hypothetical cohort of 100,000 injectable contraceptive users in Senegal. We used the model to estimate incremental costs per disability-adjusted life year (DALY) averted. The analysis derived model inputs from DMPA-SC self-injection continuation and costing research studies and peer-reviewed literature. We evaluated the cost-effectiveness from societal and health system perspectives and conducted one-way and probabilistic sensitivity analyses to test the robustness of results.

Results

Compared to health-worker-administered DMPA-IM, self-injected DMPA-SC could prevent 1402 additional unintended pregnancies and avert 204 maternal DALYs per year for this hypothetical cohort. From a societal perspective, self-injection costs less than health worker administration regardless of the training approach and is therefore dominant. From the health system perspective, self-injection is dominant compared to health worker administration if a one-page instruction sheet is used and one additional DMPA-SC unit is used for training and is cost-effective at $208 per DALY averted when two additional DMPA-SC units are used. Sensitivity analysis showed estimates were robust.

Conclusions

Self-injected DMPA-SC averted more pregnancies and DALYs and cost less from the societal perspective compared to health-worker-administered DMPA-IM and hence is dominant. Using fewer DMPA-SC units for practice or demonstration improves cost-effectiveness of self-injection from the health system perspective.

Implications

Evidence from Senegal shows that self-injection of DMPA-SC can be dominant or cost-effective from both health system and societal perspectives relative to DMPA-IM from health workers even if women practice injecting or health workers demonstrate with one or two DMPA-SC units. Evidence on whether practice or demonstration is required for client training would be useful.

Introduction of Subcutaneous Depot Medroxyprogesterone Acetate (DMPA-SC) Injectable Contraception at Facility and Community Levels: Pilot Results From 4 Districts of Uganda

Over 1 year, the NGO-led project provided more than 14,000 units of DMPA-SC, mostly in community settings and to a substantial proportion (43%) of young women. The share of injectables increased significantly, as did the volume of all methods provided, including short-acting, long-acting, and permanent methods.

Reproductive Health Uganda (RHU), a local NGO, introduced subcutaneous depot medroxyprogesterone acetate (DMPA-SC, brand name Sayana Press) in 4 districts of Uganda between April 2016 and March 2017. RHU trained public and private facility providers on all family planning methods including DMPA-SC; trained community health workers (known as village health teams, VHTs) to give family planning counseling, provide short-acting methods including DMPA-SC, and make referrals for long-acting and permanent methods; conducted mobile outreach and raised awareness of family planning; and provided family planning commodities. We used a retrospective cross-sectional evaluation design drawing on data from (1) in-depth interviews with 32 facility- and community-based providers; (2) key informant interviews with 7 policy makers and program staff; and (3) family planning program statistics from 4 RHU clinics, 26 mobile outreach sites, and 40 VHTs in 4 study districts. Data collection took place between April and June 2017. Over 12 months, 14,273 units of DMPA-SC were provided in RHU clinics, by mobile outreach teams, and by VHTs. DMPA-SC units were mostly administered in community settings either by VHTs (70%) or at mobile outreach events (26%). A substantial proportion (43%) of DMPA-SC units were administered to young people (<25 years), a significantly higher proportion compared with other methods provided to this age group through the project (P<.001), except condoms. In addition, a greater proportion of DMPA-SC units provided at the community level by VHTs were used by young people (45%) compared with units provided at outreach (36%) or in clinics (35%). Overall, injectables (DMPA-SC and intramuscular DMPA combined) came to represent 43% of all contraceptive methods provided, up from a baseline of 20%. This shift occurred despite significant increases in the volume of all other methods provided (P<.001). Qualitative data revealed various factors that facilitated introduction, including comprehensive training, commodity availability, strong referral links, and early community engagement. RHU's experience supports the viability of community-based delivery of DMPA-SC and identifies opportunities to strengthen this approach. There is further evidence that DMPA-SC may be popular with young people, especially in community settings.

Continuation of self-injected versus provider-administered contraception in Senegal: a nonrandomized, prospective cohort study

Objectives

The primary objective of this study was to compare the 12-month continuation rate for women who self-injected subcutaneous depot-medroxyprogesterone acetate (DMPA-SC) with that for women receiving intramuscular depot-medroxyprogesterone acetate (DMPA-IM) from a provider. This research contributes to the broader goal of identifying solutions to support women to use contraception for their full desired duration.

Study design

Participants were clients from 13 clinics in the Dakar and Thiés regions of Senegal who had decided to use injectable contraception prior to enrollment. They chose self-injection of DMPA-SC or provider administration of DMPA-IM. Self-injectors were trained and given three units of DMPA-SC. The provider-injected group received DMPA-IM and returned to the clinics for future injections. We interviewed participants at baseline and after the second, third and fourth injections (the equivalent of 12 months of contraceptive coverage). We employed Kaplan–Meier methods to estimate continuation probabilities, with a log-rank test to compare differences between groups. A multivariate Cox regression identified factors correlated with discontinuation.

Results

The 12-month continuation rate for 650 women self-injecting DMPA-SC was 80.2%, while that for 649 women receiving DMPA-IM from a provider was 70.4% (p<.01). The difference in continuation between self-injectors and those receiving DMPA from a provider remained significant in a multivariate Cox regression model. The primary reason for discontinuation in both groups (44.7% self-injected; 44.5% provider-injected) was forgetting to reinject or reinjecting late. Fewer women reported side effects in the self-injection group than in the provider-administered group.

Conclusions

The higher 12-month continuation rate for women self-injecting DMPA-SC relative to provider-administered DMPA-IM suggests that self-injection may help prevent pregnancy more consistently and continuously.

Implications

Discontinuation of injectable contraception among women wishing to avoid pregnancy may increase unmet need in francophone West Africa. This study showed higher 12-month continuation rates for women who self-injected DMPA-SC, suggesting that this delivery method may improve injectable continuation.

Continuation of injectable contraception when self-injected vs. administered by a facility-based health worker: a nonrandomized, prospective cohort study in Uganda

Objective

The purpose of this study was to compare 12-month continuation rates for subcutaneous depot medroxyprogesterone acetate (DMPA-SC) administered via self-injection and DMPA-IM administered by a health worker in Uganda.

Study design

Women seeking injectable contraception at participating health facilities were offered the choice of self-injecting DMPA-SC or receiving an injection of DMPA-IM from a health worker. Those opting for self-injection were trained one-on-one. They self-injected under supervision and took home three units, a client instruction guide and a reinjection calendar. Those opting for DMPA-IM received an injection and an appointment card for the next facility visit in 3 months. We interviewed participants at baseline (first injection) and after 3 (second injection), 6 (third injection) and 9 (fourth injection) months, or upon discontinuation. We used Kaplan–Meier methods to estimate continuation probabilities, with a log-rank test to compare differences between groups. A multivariate Cox regression identified factors correlated with discontinuation.

Results

The 12-month continuation rate for the 561 women self-injecting DMPA-SC was .81 [95% confidence interval (CI) .78–.84], and for 600 women receiving DMPA-IM from a health worker, it was .65 (95% CI .61–.69), a significant difference at the .05 level. There were no differences in pregnancy rates or side effects. The multivariate analysis revealed that, controlling for covariates, self-injecting reduced the hazard for discontinuing by 46%. A significant interaction between injection group and age suggests that self-injection may help younger women continue injectable use.

Conclusions

The significant difference in 12-month continuation between women self-injecting DMPA-SC and women receiving DMPA-IM from a health worker — which remains significant in a multivariate analysis — suggests that self-injection may improve injectable contraceptive continuation.

Implications

While injectable contraceptives are popular throughout much of sub-Saharan Africa, they have high rates of discontinuation. This study is the second from an African country to demonstrate that self-injection may improve injectable continuation rates and may do so without increasing the risk of pregnancy or adverse events.

Hormonal Contraception and HIV-1 Acquisition: Biological Mechanisms

Access to effective affordable contraception is critical for individual and public health. A wide range of hormonal contraceptives (HCs), which differ in composition, concentration of the progestin component, frequency of dosage, and method of administration, is currently available globally. However, the options are rather limited in settings with restricted economic resources that frequently overlap with areas of high HIV-1 prevalence. The predominant contraceptive used in sub-Saharan Africa is the progestin-only three-monthly injectable depot medroxyprogesterone acetate. Determination of whether HCs affect HIV-1 acquisition has been hampered by behavioral differences potentially confounding clinical observational data. Meta-analysis of these studies shows a significant association between depot medroxyprogesterone acetate use and increased risk of HIV-1 acquisition, raising important concerns. No association was found for combined oral contraceptives containing levonorgestrel, nor for the two-monthly injectable contraceptive norethisterone enanthate, although data for norethisterone enanthate are limited. Susceptibility to HIV-1 and other sexually transmitted infections may, however, be dependent on the type of progestin present in the formulation. Several underlying biological mechanisms that may mediate the effect of HCs on HIV-1 and other sexually transmitted infection acquisition have been identified in clinical, animal, and ex vivo studies. A substantial gap exists in the translation of basic research into clinical practice and public health policy. To bridge this gap, we review the current knowledge of underlying mechanisms and biological effects of commonly used progestins. The review sheds light on issues critical for an informed choice of progestins for the identification of safe, effective, acceptable, and affordable contraceptive methods.

Injectable contraception: updates and innovation

PURPOSE OF REVIEW

Injectable contraception is a highly effective form of birth control that is globally popular. Recent research has focused on ways to make injectables such as depot medroxyprogesterone acetate (DMPA) more accessible and to improve the side-effect profile of injectables. This review will focus on new directions and approaches to the use of injectable contraception.

RECENT FINDINGS

Research in the area of injectable contraception has focused on improving access for women through home or self-injection, and also task-shifting and community-based distribution in low-resource areas. Specific to DMPA, studies have focused on lowering the overall dose of medication while maintaining efficacy, and improving drug-delivery systems. More research into the association between DMPA and HIV is needed, and also the effects of administration of DMPA at the time of medication abortion.

SUMMARY

Injectable contraceptives are an important part of the global method mix of highly effective birth control. Improving the accessibility and side effect profile of commodities such as DMPA will make injectables even more valuable for women seeking effective contraception.

The feasibility of contraceptive injections at the community pharmacy

PURPOSE

The progestogen-only intramuscular injectable Depo-Provera^® (depot medroxyprogesterone acetate) is an effective contraceptive method, but users need to attend a clinic every 12-13 weeks for a repeat injection from a doctor/nurse. This limits convenience of the method and may affect continuation rates. We conducted a pilot study to examine the feasibility and acceptability of users receiving the subcutaneous form of the contraception injection from pharmacists in the community pharmacy setting.

MATERIALS AND METHODS

Existing users of Depo-Provera^®, who wished to switch to the subcutaneous preparation with the same active ingredient (Sayana Press^®) were invited to attend 1 of 11 community pharmacies for up to three repeat injections, given by a pharmacist. Evaluation consisted of (i) self-administered questionnaires of women and (ii) interviews with participating pharmacists, at study exit on their respective experiences.

RESULTS

Global unavailability of the product during the study adversely affected recruitment and retention. 50 women were recruited. Only 48 injections were delivered at the pharmacy out of a possible 150 (34%). About 26 participants received no injections at the pharmacy and only seven (14%) participants received all three injections at the pharmacy. Participants reported mixed experiences, with some welcoming the intervention but others experiencing difficulty with pharmacist availability. Pharmacists were enthusiastic about this expansion of their role, and did not view their availability as a barrier to service delivery.

CONCLUSIONS

Delivery of the subcutaneous contraceptive injectable from a community pharmacy may be feasible but availability of sufficient numbers of pharmacists trained in this technique is necessary for a robust model of service delivery.

Evaluating the feasibility and acceptability of self-injection of subcutaneous depot medroxyprogesterone acetate (DMPA) in Senegal: a prospective cohort study

Objectives

Expanding contraceptive options through self-injection may improve access and confidentiality. There are few published studies on contraceptive self-injection in sub-Saharan Africa and none in West Africa, a region with high unmet need. This study was performed to assess feasibility of subcutaneous DMPA self-injection in Senegal; objectives were to (1) measure the proportion of participants who self-injected competently 3 months after training, (2) measure the proportion who self-injected on time (defined conservatively as within 7 days of reinjection date), and (3) assess acceptability of self-injection.

Study design

In this prospective cohort study, 378 women aged 18–49 years were trained to self-inject by study nurses. Three months later, women returned unprompted to the clinic to self-inject, and technique and visit timing were evaluated. Women continuing with a third self-injection were followed up at home after their next scheduled injection date. At each interaction, participants were interviewed to learn about their experience; additional questions during the final home visit focused on storage and disposal practices, and acceptability.

Results

Among the 337 participants followed up 3 months post-training, 310 self-injected, and 87% did so competently. Factoring in women who declined to self-inject, electing to have the provider administer the injection instead, a total of 80% [95% confidence interval (CI) = 75–84%] self-injected competently 3 months post-training, and 84% [95% CI=80–88%] reinjected on time, while 72% [95% CI=67–77%] were both on time and competent. The vast majority (93%) expressed a desire to continue.

Conclusions

Self-injection is feasible and acceptable among most study participants in Senegal.

Implications

These first research results on contraceptive self-injection in West Africa indicate initial feasibility and acceptability of the practice. Results underscore the importance of designing self-injection programs that empower and support women, including those with limited education.

A prospective cohort study of the feasibility and acceptability of depot medroxyprogesterone acetate administered subcutaneously through self-injection

Objectives

Evidence on contraceptive self-injection from the United States and similar settings is promising, and the practice may increase access. There are no published studies on the feasibility of contraceptive self-injection in sub-Saharan Africa to date. The purpose of this study was to assess feasibility of subcutaneous depot medroxyprogesterone acetate self-injection in Uganda, with specific objectives to (a) measure the proportion of participants who self-injected competently, (b) measure the proportion who self-injected on time 3 months after training (defined conservatively as within 7 days of their reinjection date) and (c) assess acceptability.

Study design

In this prospective cohort study, 380 18–45-year-old participants completed self-injection training by licensed study nurses, guided by a client instruction booklet, and practiced injection on prosthetics until achieving competence. Nurses supervised participants' self-injection and evaluated injection technique using an observation checklist. Those judged competent were given a Sayana® Press unit, instruction booklet and reinjection calendar for self-injection at home 3 months later. Participants completed an interview before and after self-injection. Nurses visited participants at home following reinjection dates; during the follow-up visit, participants demonstrated self-injection on a prosthetic, injection technique was reevaluated, and a postreinjection interview was completed.

Results

Of 368 participants followed up 3 months posttraining, 88% [95% confidence interval (CI) = 84–91] demonstrated injection competence, and 95% (95% CI=92–97) reinjected on time, while 87% (95% CI=84–90) were both on time and competent. Nearly all (98%) expressed a desire to continue.

Conclusions

Self-injection is feasible and highly acceptable among most study participants in Uganda.

Implications

The first research results on contraceptive self-injection in sub-Saharan Africa indicate initial feasibility and acceptability of the practice 3 months after women received one-on-one training and a highly visual training and memory aid. Results can inform self-injection programs which aim to increase women's autonomy and access to injectable contraception.

Self-administration of injectable contraceptives: a systematic review

Background

The contraceptive injectable is a safe and effective method that is used worldwide. With the variety of injectable delivery systems, there is potential for administration by the woman herself. Self‐administration of the contraceptive injectable is the subject of this systematic review.

Objectives

To assess how effective and safe the contraceptive injectable method is when women themselves perform/administer it, compared with when the usual healthcare providers administer it.

Search strategy

We searched PubMed, Popline, Cochrane, CINAHL, and Embase for articles with subject headings or text words related to ‘self‐administration’ and ‘contraception’.

Selection criteria

Studies that compared the administration of the contraceptive injectable by the woman herself versus administration by the healthcare provider were included. Outcomes of interest were continuation rates, safety, and the women's overall satisfaction with the contraceptive provider and method.

Data collection and analysis

We undertook data extraction, descriptive analysis, and assessment of risk of bias.

Main results

Three studies met the inclusion criteria. The best available evidence shows that there may be little or no difference in continuation rates when women self‐administer contraceptive injections (326 per 1000 women; 95% CI 192–554 per 1000 women) compared with administration by healthcare providers (304 per 1000 women). Safety was not estimable as no serious adverse events were reported in any of the studies. With regards to overall satisfaction towards the provider and the method, the effect of the intervention was uncertain.

Authors’ conclusions

Findings suggest that with appropriate information and training the provision of contraceptive injectables for the woman to self‐administer at home can be an option in some contexts.

Tweetable abstract

This review assessed the continuation rates and safety of self‐administration of the contraceptive injection.

This review assessed the continuation rates and safety of self‐administration of the contraceptive injection.

Home or office etonogestrel implant insertion after pregnancy: a randomized trial

OBJECTIVES

To evaluate whether home visits for contraceptive implant insertion result in an increase in postpartum uptake compared to clinic insertion and to assess the feasibility of home insertions.

STUDY DESIGN

We randomized women within 10 weeks of a birth or dilation and curettage (D&C) for abortion or miscarriage to home or standard office insertion. The primary outcome was successful insertion of the implant. To achieve 80% power to detect a 40% difference in visit attendance, 20 women were assigned to each group. The secondary outcome was attendance of the 4-week postpartum visit.

RESULTS

From June 2013 through February 2014, we screened 45 women and 40 were randomly assigned to home and office insertion visits. We enrolled 37 postpartum women and 3 women post-D&C. Because of the significant under enrollment of the latter, we chose to report results of only the postpartum women. The results were similar whether we included or excluded post-abortion women. A majority of women desired a home visit for their implant insertion appointment at time of enrollment. Postpartum appointment attendance rates were similar between home and office visits at 53% and 50% (p=1.00), respectively. Home visits resulted in a trend toward increased implant uptake [12/19 (63%) vs 6/18 (33%), p=.10].

CONCLUSION

Home insertion of the contraceptive implant may be a feasible option. Future studies that examine the feasibility and uptake in both postpartum and post-D&C women are warranted.

IMPLICATIONS

Women reported preference for home insertion visits in this pilot study. We also showed that a greater proportion of women received the etonogestrel implant at a home visit compared to the current standard of care, which may warrant larger studies that would have sufficient power to evaluate smaller differences.

Interest in self-administration of subcutaneous depot medroxyprogesterone acetate in the United States

OBJECTIVE

Subcutaneous depot medroxyprogesterone acetate (DMPA-SC) is a low-dose formulation of depot medroxyprogesterone acetate (DMPA) that nonmedical personnel can administer safely and effectively. We sought to determine United States women's interest in self-administration of DMPA-SC to understand whether such use can overcome barriers to contraceptive access.

STUDY DESIGN

We analyzed survey data on contraceptive attitudes collected in March-July 2011 from 1592 women at 13 family planning and six abortion clinics throughout the US. A mixed-effects logistic regression model with random site effects examined the determinants of interest in self-administering DMPA-SC.

RESULTS

Overall, 21% [95% confidence interval (CI): 19%-23%] of women reported interest in self-administration. A multivariable model found that women currently using DMPA (Adjusted Odds Ratio [AOR]=3.93, 95% CI: 2.37-6.53, p<.001) and women who previously used DMPA (AOR=1.71, 95% CI: 1.26-2.32, p<.001) were more likely to have an interest in DMPA-SC than those who never used it. Women reporting difficulty obtaining or refilling a prescription were almost twice as likely to have interest in DMPA-SC as women who reported no difficulty (AOR=1.99, 95% CI: 1.43-2.77, p<.001). Women surveyed at abortion sites were more likely to report interest in self-administration than women surveyed at family planning sites (AOR=1.55, 95% CI: 1.05-2.30, p<.05). Interest in DMPA-SC was primarily driven by a desire to eliminate unnecessary return visits to a facility for repeat injections.

CONCLUSIONS

Offering women the option to self-administer DMPA-SC at home can expand access and tailor contraceptive provision to the needs of clients, thus supporting client-centered care. To the extent that self-administration may improve contraceptive continuation, DMPA-SC can prevent unintended pregnancies among women who discontinue DMPA use because of difficulty returning for repeat injections.

IMPLICATIONS

There is substantial interest in self-administration of DMPA-SC among current DMPA users, women who have recently had an abortion and women reporting difficulty returning to a family planning provider. Offering self-administration of DMPA-SC could potentially increase contraceptive continuation, reduce unintended pregnancies and enhance reproductive autonomy among DMPA users.

Injectable agents for pre-exposure prophylaxis: lessons learned from contraception to inform HIV prevention

PURPOSE OF REVIEW

Long-acting injectable (LAI) forms of preexposure prophylaxis (PrEP) are in clinical trials, generating much hope for HIV prevention. But this is not the first time that an injectable form of preventive medication has emerged: the contraceptive agent depomedroxyprogesterone acetate (DMPA) has an important precedent. DMPA's long journey, its initial reception, and ongoing implementation challenges can help inform the field of HIV prevention as we plan for approval, acceptance, and scale-up of LAI-PrEP.

RECENT FINDINGS

DMPA faced a long regulatory journey in the USA, with a lag of 25 years from initial application (1967) to approval (1992). Acceptance after introduction was rapid, but challenges hampered scale-up. Specific lessons learned include that extensive acceptability work is needed in parallel to product development. Also, low continuation rates, challenges with timing of initiation, and difficulty ensuring access for the most vulnerable populations have limited DMPA's impact. A new subcutaneous formulation presents opportunities for administration outside of clinical settings and for self-administration.

SUMMARY

Those involved in LAI-PrEP development and those who plan to be involved in its future implementation must consider these lessons and possible solutions from DMPA to ensure a successful future for this new HIV prevention modality.
