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

ABSTRACT:

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.

Project description:ObjectivesExpanding 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 designIn 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.ResultsAmong 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.ConclusionsSelf-injection is feasible and acceptable among most study participants in Senegal.ImplicationsThese 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.

Project description:To evaluate feasibility, acceptability, continuation, and trough serum levels following self-administration of subcutaneous (sc) depot medroxyprogesterone acetate (DMPA).Women presenting to a family planning clinic to initiate, restart or continue DMPA were offered study entry. Participants were randomized in a 2:1 ratio to self- or clinician administered sc DMPA 104 mg. Those randomized to self-administration were taught to self-inject and were supervised in performing the initial injection; they received printed instructions and a supply of contraceptive injections for home use. Participants randomized to clinician administration received usual care. Continued DMPA use was assessed by self-report and trough medroxyprogesterone acetate levels at 6 and 12 months.Two hundred fifty women were invited to participate, and 137 (55%) enrolled. Of these, 91 were allocated to self-administration, and 90/91 were able to correctly self-administer sc DMPA. Eighty-seven percent completed follow-up. DMPA use at 1 year was 71% for the self-administration group and 63% for the clinic group (p=0.47). Uninterrupted DMPA use was 47% and 48% for the self and clinic administration groups at 1 year (p=0.70), respectively. Serum analyses confirmed similar mean DMPA levels in both groups and therapeutic trough levels in all participants.Sixty-three percent of women approached were interested in trying self-administration of DMPA, even in the context of a randomized trial, and nearly all eligible for enrollment were successful at doing so. Self-administration and clinic administration resulted in similar continuation rates and similar DMPA serum levels. Self-administration of sc DMPA is feasible and may be an attractive alternative for many women.Self-administration of sc DMPA is a feasible and attractive option for many women. Benefits include increased control over contraceptive measures and less time spent on contracepting behaviors. Globally, self-administration has the potential to revolutionize contraceptive uptake by increasing the number of women with access to DMPA.

Project description:ObjectiveTo examine the rate of ovulatory disruption when intramuscular depot medroxyprogesterone acetate (DMPA) is administered across graded stages of dominant follicle development.Study designWe assigned enrolled participants to one of three preassigned dominant follicle size groups: 12-14?mm, 15-17?mm and?? 18?mm. We followed dominant follicles via serial transvaginal ultrasound (TVUS) until the follicles reached their assigned size, at which time we administered DMPA. For 5 consecutive days thereafter, we followed the follicles via TVUS to observe follicle rupture and obtained serum luteinizing hormone (LH), estradiol, and progesterone concentrations. In the following 2 weeks, we collected serum progesterone concentrations twice weekly to detect possible ovulatory delay or dysfunction. We also collected serum medroxyprogesterone acetate (MPA) concentrations at 1 and 24?h after DMPA administration to examine against ovulatory outcomes.ResultsTwenty-six of 29 enrolled women completed the study. DMPA suppressed ovulation in 17/26 (65%) and caused ovulatory dysfunction in 1/26 (4%) participants. Larger follicles were more likely to rupture despite DMPA (12-14?mm: 0/10 (0%); 15-17?mm: 3/10 (30%); ? 18?mm: 6/6 (100%); p?<?.01). Pre-DMPA LH concentrations ranged from 13.8 to 93.7?IU/L (mean 49.0?IU/L) in cases of follicle rupture. We observed no cases of follicle rupture when DMPA was administered through cycle day 12. All 24-h MPA concentrations exceeded those needed for ovulation suppression.ConclusionDMPA suppressed and additionally disrupted ovulation in 65% and 4% of observed cycles, respectively. DMPA may provide effective emergency contraception as well as ongoing contraception if administered prior to an expected ovulation and specifically before the LH surge.ImplicationsDMPA may be an alternative form of emergency contraception that can also self-bridge to ongoing contraception. As ovulation was not observed among any follicles when DMPA was given through cycle day 12, women who initiate DMPA up through cycle day 12 may not require backup contraception.

Project description:BackgroundThe vaginal microbiome plays a key role in women's reproductive health. Use of exogenous hormones, such as intramuscular depot medroxyprogesterone acetate (DMPA-IM), may alter the composition of vaginal bacterial community.MethodsVaginal swab samples were collected from postpartum Kenyan women initiating DMPA-IM or nonhormonal contraception (non-HC). Bacterial vaginosis was assessed by Nugent score (Nugent-BV) and bacterial community composition was evaluated using broad-range 16S ribosomal RNA gene polymerase chain reaction with high-throughput sequencing. Changes in Nugent score, alpha diversity (Shannon diversity index), and total bacterial load between contraceptive groups from enrollment to 3 months after initiation were estimated using multivariable linear mixed effects regression.ResultsAmong 54 human immunodeficiency virus-negative women, 33 choosing DMPA-IM and 21 choosing non-HC, Nugent-BV was more common among DMPA-IM users at enrollment. At follow-up, Nugent score had decreased significantly among DMPA-IM users (change, -1.89; 95% confidence interval [CI], -3.53 to -.25; P = .02) while alpha diversity remained stable (0.03; -.24 to .30; P = .83). Conversely, Nugent score remained relatively stable among non-HC users (change, -0.73; 95% CI, -2.18 to .73; P = .33) while alpha diversity decreased (-0.34; -.67 to -.001; P = .05). The total bacterial load decreased slightly in DMPA-IM users and increased slightly among non-HC users, resulting in a significant difference in change between the contraceptive groups (difference, -0.64 log10 gene copies per swab sample; 95% CI, -1.19 to -.08; P = .02). While significant changes in Nugent score and alpha diversity were observed within contraceptive groups, changes between groups were not significantly different.ConclusionsPostpartum vaginal bacterial diversity did not change in DMPA-IM users despite a reduction in Nugent-BV, but it decreased significantly among women using non-HC. Choice of contraception may influence Lactobacillus recovery in postpartum women.
