Pregnancy bleeding/pain triage workflow

Scope

Use for

Initial triage of early-pregnancy pain or bleeding, including pregnancy of unknown location, before emergency or early-pregnancy service assessment.

Not for

• Hemodynamic instability requiring immediate emergency transfer.
• Later-pregnancy pain/bleeding and definitive obstetric or surgical management.

Immediate actions

• Assess vital signs, gestational context, pain and bleeding; ask about syncope, shoulder-tip pain and previous ectopic pregnancy.
• Consider ectopic pregnancy even without known risk factors or abnormal vital signs. Obtain a pregnancy test if status is unknown without delaying urgent transfer.
• This pathway covers early pregnancy only; route later-pregnancy pain or bleeding directly to the appropriate urgent maternity/ED service.

Red flags: escalate now

If any of these are present, stop routine steps and follow the urgency stated. Activate emergency care for instability or findings that need immediate transfer.

• Arrange immediate ED/obstetric assessment for heavy bleeding, severe pain, syncope, peritoneal signs or suspected infection; use EMS for instability or collapse.
• Suspected ruptured ectopic pregnancy needs immediate emergency transfer. A low or falling hCG does not make worsening symptoms safe to observe.
• If time-sensitive assessment or reliable follow-up cannot be secured, use the ED rather than leaving a potentially ectopic pregnancy unmonitored.

First-line plan

• For stable patients, arrange timely early-pregnancy/gynecology assessment and ultrasound to establish pregnancy location; do not use hCG alone to locate a pregnancy.
• A pregnancy of unknown location remains potentially ectopic: agree a specialist-led plan for serial hCG (usually approximately 48 hours apart, not earlier) and repeat ultrasound as indicated.
• Record blood group/Rh information when available and confirm any prophylaxis decision with the current local obstetric protocol; do not delay transfer for routine tests.

Follow-up and monitoring

• Confirm who receives results and reassesses the patient until location or resolution is established; provide a 24-hour emergency contact route.
• New/worsening pain, bleeding, dizziness or shoulder-tip pain warrants immediate reassessment regardless of previous hCG or ultrasound findings.
• Explain uncertainty sensitively, provide written instructions and confirm the handoff with the receiving service.

Before the patient leaves

Return precautions you can say as written:

“If symptoms get worse, new warning signs appear, or you cannot follow the plan from this visit, seek urgent care now.”

• Point to the red flags above that apply to this patient.
• Confirm follow-up timing and where to go after hours.
• Attach a relevant handout to reinforce the plan.
• Document disposition, rationale, unresolved uncertainty, and that precautions were understood.
