Outpatient Clinic Approach for Elective Termination of Pregnancy

Classification of Concern

Elective procedure, time-sensitive, non-traumatic 1, 2
Urgency increases with advancing gestational age due to reduced procedural options, higher complication rates, and increased costs 3, 1

Focused History (Essential Questions)

Last menstrual period and estimated gestational age - determines method eligibility and urgency 1, 4
Certainty of decision and understanding of options - 87% of women have high confidence before counseling, but informed consent requires discussion of all methods 3
Medical contraindications: bleeding disorders, anticoagulation, severe anemia, cardiac disease, renal/hepatic impairment 1, 2, 5
Rh status - critical for immunoprophylaxis planning 1, 6
Current medications - particularly anticoagulants, corticosteroids, or drugs metabolized by CYP3A4 5
Preference for medical vs. surgical approach - patient autonomy is paramount in method selection 3, 7
Access to emergency care and support system - required for safe outpatient medical abortion 3, 4
History of ectopic pregnancy or current symptoms - pelvic pain, unilateral pain, or abnormal bleeding patterns 4, 8

Differential Diagnosis

Top 3 Dangerous (Must Exclude)

Ectopic pregnancy - can present with positive pregnancy test and bleeding; requires ultrasound confirmation of intrauterine pregnancy before proceeding 6, 4
Molar pregnancy - requires different management; ultrasound shows characteristic "snowstorm" pattern 6
Septic abortion/infection - maternal tachycardia, purulent discharge, uterine tenderness; requires immediate antibiotics and urgent evacuation 6

Top 3 Common (Expected Presentations)

Viable intrauterine pregnancy requesting elective termination - confirmed by ultrasound with cardiac activity 4, 8
Early pregnancy loss (missed abortion) with termination request - absent cardiac activity with CRL ≥7mm 6
Uncertain viability requiring serial evaluation - suboptimal β-hCG rise or inconclusive ultrasound 6

Top 3 Rare (Consider if Atypical)

Heterotopic pregnancy (intrauterine + ectopic) - extremely rare but possible, especially with assisted reproduction 6
Coagulopathy or bleeding disorder - may present with excessive bleeding risk 6
Undiagnosed cardiac or pulmonary disease - may decompensate with procedure or prostaglandins 1, 2

Diagnostic Workup

Mandatory baseline investigations:

Transvaginal ultrasound - confirm intrauterine pregnancy, measure gestational age (CRL or mean sac diameter), exclude ectopic pregnancy 6, 4
Rh blood type - all Rh-negative women require 50 μg anti-D immunoglobulin 1, 6
Hemoglobin/hematocrit - baseline for bleeding risk assessment 6
Pregnancy test (qualitative) - document positive result 5, 4

Additional testing if indicated:

Quantitative β-hCG - only if viability uncertain or ectopic pregnancy suspected; serial measurements show appropriate rise or decline 6
STI screening - gonorrhea/chlamydia testing reduces post-procedure infection risk when combined with prophylactic antibiotics 4
Coagulation studies - only if bleeding disorder suspected or on anticoagulation 6

Empiric Treatment Options (Pharmacotherapeutic)

First Trimester (≤9 weeks): Medical Abortion Preferred for Outpatient Setting

Medical abortion can be performed in outpatient or home settings before 9 weeks, offering significant cost and convenience advantages 1, 4

Regimen:

Mifepristone 200 mg orally followed 24-48 hours later by misoprostol 800 μg vaginally or buccally 1, 5, 4, 9
Success rate: 95-97% at gestations <9 weeks 4, 9
Patient must take mifepristone with food and swallow whole (do not split, crush, or chew) 5

If mifepristone unavailable:

Misoprostol 800 μg vaginally alone, repeated every 3 hours up to 5 doses 4, 9
Lower efficacy (91.5%) and requires multiple doses 6, 4

Prophylactic medications:

Doxycycline 100 mg BID for 7 days OR azithromycin 500 mg single dose - reduces infection risk from 5-20% to 1.3% 1, 4
Ibuprofen 600-800 mg every 6 hours PRN for pain management 4
Antiemetics (ondansetron 4-8 mg) - gastrointestinal upset occurs in up to 50% 4, 7

Rh immunoprophylaxis:

Anti-D immunoglobulin 50 μg IM for all Rh-negative women at time of mifepristone administration 1, 6

First Trimester (9-12 weeks): Surgical or Medical Options

At 9-12 weeks, both methods remain effective, but surgical evacuation has lower complication rates 1, 6

Surgical: Vacuum Aspiration (Manual or Electric)

Success rate: 97% 4, 7
Hemorrhage risk: 9.1% (vs 28.3% medical) 1, 2
Infection risk: 1.3% (vs 23.9% medical) 1, 2
Retained tissue: 1.3% (vs 17.4% medical) 6
Performed as outpatient/day case with local anesthesia or conscious sedation 3, 4

Medical: Extended Regimen

Mifepristone 200 mg followed by misoprostol 800 μg vaginally, repeated every 3 hours (up to 5 doses) 9
Success rate: 91.7% at 9-12 weeks 9
Requires closer monitoring and hospital setting recommended 1, 2

Second Trimester (≥13 weeks): Surgical Preferred

Dilation and evacuation (D&E) is the safest procedure for second-trimester termination and should be performed in a hospital setting by experienced providers 1, 2

Dramatically lower complication rates compared to medical induction 1, 2
Requires referral to specialist center with appropriate anesthesia and emergency capabilities 1, 2
Avoid prostaglandin F compounds - use prostaglandin E1 (misoprostol) or E2 if medical method chosen 2

Critical Red Flag Symptoms (Patient Education)

Instruct patient to seek immediate emergency care for:

Soaking through 2 or more maxi pads per hour for 2 consecutive hours - suggests hemorrhage requiring intervention 6, 4
Fever >38°C (100.4°F) or chills - suggests infection/sepsis requiring antibiotics and possible evacuation 6
Severe abdominal pain unrelieved by ibuprofen - may indicate perforation (surgical only), ectopic pregnancy, or infection 6, 4
Foul-smelling vaginal discharge - suggests endometritis 6
No bleeding within 24 hours of misoprostol (medical abortion) - suggests failed abortion or ectopic pregnancy 4
Persistent nausea/vomiting preventing oral intake - may require IV hydration and antiemetics 4
Dizziness, syncope, or signs of hemodynamic instability - suggests significant blood loss 6

Natural History/Untreated Prognosis

Expectant management of elective termination is not applicable and carries unacceptable risks:

Maternal morbidity: 60.2% with expectant management vs 33.0% with abortion care 6
Intraamniotic infection: 38.0% vs 13.0% with abortion care 6
Postpartum hemorrhage: 23.1% vs 11.0% with abortion care 6
Coagulopathy risk increases with prolonged retention of non-viable pregnancy 6
Psychological distress from unwanted pregnancy continuation 3
Reduced procedural options as gestational age advances - medical abortion efficacy decreases and surgical complexity increases 3, 1

Follow-Up Schedule

Medical Abortion:

7-14 days post-procedure: Clinical examination with ultrasound to confirm complete expulsion 4, 9
Quantitative β-hCG at follow-up: Should decrease >97.5% from baseline; if not, suggests retained products 9
Alternative: Home urine pregnancy test at 4 weeks (should be negative); if positive, requires clinical evaluation 4

Surgical Abortion:

2-4 weeks post-procedure: Clinical follow-up only if symptomatic (bleeding, pain, fever) 4
Routine follow-up not required if asymptomatic, but should be offered 4

Contraceptive Counseling (Immediate):

Ovulation resumes within 2-4 weeks post-abortion 6
Combined hormonal contraceptives or implants can be initiated immediately without waiting for next menses 6
If started within 7 days of abortion, no backup contraception needed 6

Common Pitfalls and How to Avoid Them

Delaying care is the most critical error - earlier abortion offers more options, improved safety, and lower costs; every day of delay reduces choice and increases complications 3, 1
Failing to exclude ectopic pregnancy - always confirm intrauterine pregnancy with ultrasound before proceeding; presence of intrauterine gestational sac rules out ectopic 6, 4
Waiting for fever to diagnose infection - maternal tachycardia, purulent discharge, and uterine tenderness are sufficient; initiate antibiotics and evacuate urgently 6
Omitting Rh immunoprophylaxis - 32% of spontaneous abortions have fetomaternal hemorrhage; all Rh-negative women require 50 μg anti-D 1, 6
Inadequate pain management - preemptive NSAIDs significantly improve patient experience; prescribe scheduled ibuprofen, not PRN only 4
Not offering both medical and surgical options - patient autonomy requires presenting both methods with accurate complication data 3, 7
Assuming patient needs more time to decide - 87% have high confidence before counseling; respect autonomous decisions and avoid paternalistic delays 3
Using expectant management - absolutely contraindicated for elective termination due to unacceptable morbidity (60.2%) and infection rates (38.0%) 6
