Self-administration of subcutaneous depot medroxyprogesterone acetate for contraception: feasibility and acceptability

Background: The objectives of the study were to assess feasibility, continuation rates and patient satisfaction with self-administration of subcutaneous depot medroxyprogesterone acetate (DMPA-SC). Materials and Methods: The study included 50 DMPA-seeking women between the ages of 18 and 49 years enrolled at two Florida Planned Parenthood health centers. Participants were taught self-injection during their initial study visit and, upon proficiency, self-injected one dose in clinic. Participants then injected a series of three more doses outside the health center over 9 months. Continuation rates, feasibility and acceptability were determined by analysis of four post-injection surveys. Results: Continuation of DMPA-SC at injection 4 was 74% (95% confidence interval 62%-86%). Overall, survey responses from the three at-home injections indicated the method to be convenient (95%), easy (87%) and recommendable to others (94%). Twenty percent of injections were met with difficulty, most commonly cited as plunger resistance. No pregnancies occurred in study. Conclusions: Continuation was high with DMPA-SC self-injection. Participants reported injection to be easy and convenient and are likely to recommend self-administration to other women. Device issues are one potential deterrent.
