Why SOAP Notes Matter in OB
I used to teach these clinical steps to midwives. Now, as an autistic nurse leader, I teach how to use these tools to improve their work-life balance. If you’re here because you’re exhausted, read my Burnout Recovery Plan.
Why use SOAP notes?
- Show your clinical reasoning clearly
- Protect you legally and clinically
- Document patient-centered care
In OB, especially arrest of dilatation, your notes should show:
- Assessment findings
- Options you offered
- Patient decisions and informed consent
- How did you monitor labor progress
Clear notes are essential because labor can change fast.
For more examples and guidance, see general SOAP Notes for Nurses.

Key Tips for OB SOAP Notes (Updated & Accurate)
1. Arrest of Dilatation: What It Is
Active phase arrest is defined as no cervical change for ≥6 hours with adequate contractions, or ≥4 hours with inadequate contractions once ≥6cm (The 2025 ACOG and CMQCC guidelines). This is exactly how you’d document it in SOAP notes for defensible, evidence-based care.
2. Patient Autonomy & Respectful Maternity Care
Documentation should include:
- Options offered and discussed
- Risks and benefits
- Patient preferences and informed consent
- How the patient was supported according to AWHONN’s respectful maternity care principles
3. SOAP Notes
The SOAP (or SOAPIE) documentation style clearly and succinctly captures assessment, patient preferences, plan, and interventions.
