Depo-Provera Administration in Ped ED

Dr. Nikki Richardson helping an old doc learn new things.

In the past we have discussed the administration of chronic medications (ex, Controller Meds for Asthma) and vaccinations that previously were felt to belong only in the Primary Care Setting. Clearly, the patient’s location matters less than what care she or he needs. There is expertise in the Primary Care realm that I do not possess… just ask my sister… but there are also issues and care that we in the ED should be more comfortable with so that we can optimize care for our patients. While many may think we need to “stay in our lane,” our lane is obviously quite broad (ex, Firearm Safety). This week, one of our STELLAR Pediatric EM Fellows, Dr. Nikki Richardson educated me about an aspect of care that I need to become more comfortable with. Here is what she taught me about Depo-Provera Administration in the Ped ED: (btw, this is the first Morsel ever authored by someone other than me — thank you Dr. Richardson!)

Birth Control from the ED: This is our Realm!

Adolescents use the Emergency Department as their Primary Care 
  • Adolescents in the US under-utilize primary care services and rely more heavily on ED services
  • Older adolescents are overrepresented in their use of ED services [Ziv, 1998]
    • Adolescents with higher levels of risky sexual behavior are more likely to report the ED as their usual source of care. [Wilson, 2000]
  • Risky sexual behavior without protection = pregnancy 
    • 1/3 of adolescent females presenting to the pediatric ED were either pregnant or could be expected to become pregnant within a year. [Chernick, 2011]
  • Adolescents are interested in birth control from the ED
    • ½ patients surveyed believe ED doctors should discuss pregnancy prevention. [Cernick, 2011]
    • ¼ were interested in starting birth control from the ED. [Chernick, 2011]
Adolescents Need Better Access to Intermediate and Long-Acting Contraception
  • When compared with older women, adolescents have higher failure rates with “typical use”. [Rosenstock, 2012]
    • Contraceptive failure for short-acting methods was 20 times higher than for long-acting methods. [Truehart, 2015]
    • Females less than 21 years old who use short acting methods are Twice as likely to experience unintended pregnancy. [Truehart, 2015]
  • Failure rates of short-acting methods are 9% in the general population, but for teenagers this can be as high as 30-38%. [Trussell, 2011]

Better Contraception Option from the Ped ED

Depo-Provera: Basics
  • Depo-Provera (depot medroxyprogesterone acetate, DMPA) is an intermediate acting birth control method that is easily administered as an IM injection from ANY healthcare setting and protects from pregnancy for 3 months.  
  • Adverse effects include:
    • Irregular bleeding, which dissipates with continued use [Truehart, 2015]
    • Possibility of weight gain 
      • Although there is reassuring evidence that most methods of hormonal contraception are not associated with weight gain, conflicting information exists with regards to DMPA. [Truehart, 2015; Vickery, 2013]
      • Despite the possible risk of weight gain, there is no contraindication to use in overweight or obese adolescents. [Truehart, 2015]
  • Contraindications to use include pregnancy, prior CVA, uncontrolled diabetes, lupus with antiphospholipid antibody syndrome, and significant liver disease. [Truehart, 2015]
Depo-Provera Prescribing from the ED: How-to
  • The Quick Start method allows initiation of hormonal contraception at the time the patient seeks care, regardless of where they are in their menstrual cycle. [Westhoff, 2002
  • Steps
    • Step 1: Preform a thorough sexual history
    • Step 2: Counsel on options including DMPA
      • Most states do not require parental consent for initiation of birth control, sexual health assessment and reproductive counseling.
      • For your states specific laws/policies see – Guttmacher.org.
    • Step 3: Obtain UPT
    • Step 4: If UPT negative, administer Depo-Provera 
    • Step 5: Post administration counseling
      • Back-up method needed for 7 days 
        • It takes 7 days to reliably change cervical mucus. [Petta, 1998]
        • In a study of 402 patients who became pregnant while using DMPA for pregnancy prevention, 45% became pregnant after the injection. [Borgotta, 2002]
      • Repeat UPT in 2-4 weeks 
        • Repeating UPT is important since a very early pregnancy may have been missed on first test. [Balkus, 2005]
      • Follow-Up: Patient needs repeat injection in 10-13 weeks.

Moral of the Morsel

  • This is our lane. Adolescent patients often rely on us in the ED as the source of their primary care.
  • Taking a pill every day is difficult for everyone… especially teenagers!
  • It is safe and effective! … and Depo-Provera can be administered from the emergency department.
  • “You get a UPT! You get a UPT! You get a UPT!” Obtain a UPT prior to administration.
  • Consider, Counsel, UPT, Administrate, and Follow-up. That is it. Repeat UPT in 2-4 weeks and repeat injection in 10-13 weeks… hopefully in the Primary Care Doctor’s office.

I enjoy taking care of patients and I finding it endlessly rewarding to help train others to do the same. I trained at the Combined Emergency Medicine and Pediatrics residency program at University of Maryland, where I had the tremendous fortune of learning from world renowned educators and clinicians. Now I have the unbelievable honor of working with an unbelievably gifted group of practitioners at Carolinas Medical Center. I strive every day to inspire my residents as much as they inspire me.
