How to Build a PMAD Referral Pathway in Your OB Practice

Why a Pathway, Not Just a Referral

The difference between a practice that reliably connects PMAD patients with care and one that doesn't is rarely clinical knowledge. Most OBGYNs know what postpartum depression is and know that it requires treatment. The gap is structural: there is no defined process, no established referral resource, and no system to track what happens after a referral is made.

A referral pathway is a set of practice-level agreements about how screening happens, what triggers a referral, who makes the referral, where patients are sent, and how the practice confirms that the referral was acted on. When this infrastructure exists, positive screens result in care. When it doesn't, they result in documentation.

This article describes a functional referral pathway that can be implemented in an OB or midwifery practice of any size.

Step 1: Establish a Standard Screening Protocol

Before building a referral pathway, you need a consistent screening process. The referral pathway starts with a positive screen -- and a positive screen requires that screening happens.

Minimum standard:

• EPDS administered at first prenatal visit and third trimester (ACOG Practice Bulletin 343)
• EPDS at the postpartum visit (4 to 6 weeks)
• EPDS at any visit where clinical symptoms or patient disclosure suggests distress

Enhanced standard:

• EPDS at first trimester, second trimester, and third trimester
• EPDS at postpartum visit and 3-month postpartum visit
• Any visit with clinical concern

The instrument should be embedded in intake paperwork or EHR intake workflows, scored before the provider enters the room, and scored by a consistent staff member (MA, LPN, or designated intake staff).

Step 2: Define the Trigger for Referral

A referral pathway requires an explicit decision rule so that every staff member in the workflow knows what a positive screen means and what to do next. Leaving the disposition to individual provider judgment on a case-by-case basis introduces variability that leads to missed referrals.

Written practice protocol:

| EPDS score | Action | |---|---| | 0 to 9 | No action beyond routine monitoring | | 10 to 12 | Provider conducts brief clinical inquiry. If functional impairment, prior history, or limited support: refer. Otherwise: rescreen at next visit. Document decision. | | 13 and above | Refer to perinatal mental health provider. Same-day referral preferred. | | Item 10 > 0 | Safety assessment. Refer regardless of total score. If active ideation: follow safety escalation protocol. |

This table should be a written document in the practice's clinical protocols, not an informal understanding.

Step 3: Identify Your Referral Resource

The single most common reason OB practices fail to act on positive PMAD screens is that they have no specific referral destination. A list of generic therapists, a state mental health directory, or "they can look someone up" are not functional referral resources.

A functional PMAD referral resource meets the following criteria:

Specialized: Accepts perinatal patients and has clinical training specific to PMADs. The credentialing marker is PMH-C (Perinatal Mental Health Certified by Postpartum Support International). General therapists without perinatal specialization are significantly less effective for PMAD presentations.

Accessible: Accepts the most common insurance plans in your patient population. Telehealth availability removes transportation and childcare barriers that significantly impair follow-through in postpartum patients.

Responsive: Has a defined intake timeline. A referral resource that takes 3 to 4 weeks to schedule a first appointment is clinically inadequate for patients with moderate-to-severe depression. Target: first contact within 1 business day; first appointment within 1 to 2 weeks.

Communicative: Is willing to confirm receipt of the patient and -- with release -- update the referring practice on whether the patient engaged with care.

Step 4: Design the Referral Workflow

With a screening protocol, a referral trigger, and a referral resource identified, the workflow connects them. A functional referral workflow in an OB practice:

When a positive screen is identified (MA or front desk):

1. Flag the score to the provider before the visit begins.
2. Place the completed EPDS form in the chart with the score visible.

During the visit (provider):

1. Acknowledge the score directly with the patient. (See our article on delivering positive PMAD screening results for clinical scripts.)
2. Assess severity, safety, and disposition.
3. If referral is indicated: complete the referral before the patient leaves the office.

- Option A: Online referral form submitted during or immediately after the visit. - Option B: Phone call to the receiving practice with the patient in the room (warm handoff). - Option C: Direct patient portal scheduling link provided to the patient with specific instructions.

1. Document: score, clinical assessment, referral made, method, date.

After the visit (MA or care coordinator):

1. If a referral was made: note it in a referral tracking log or EHR flag.
2. At the next appointment: ask the patient whether she scheduled and attended the referral appointment.

Step 5: Execute the Warm Handoff

A warm handoff is the single most impactful change any practice can make to improve PMAD referral follow-through. The mechanism is straightforward: the provider introduces the patient to the receiving practice before the visit ends, rather than leaving the patient to initiate contact independently.

Minimum warm handoff: Complete the referral form or make the intake call while the patient is present. Tell the patient specifically: "I have sent your information to [practice name]. They will contact you within 24 hours to schedule. Can I confirm your cell number so they can reach you?"

Enhanced warm handoff: Call the receiving practice directly with the patient in the room. "I have a patient with me right now who has a postpartum depression screen and I'd like to get her scheduled with you. Can you tell her what to expect?"

This takes 2 to 5 minutes. The follow-through rate increase is significant. Patients who watch the referral being made are substantially more likely to follow through than patients who are handed a business card.

Step 6: Track Referral Completion

A referral pathway without tracking is a sending mechanism without a feedback loop. Practices that track referral follow-through have higher PMAD care engagement rates -- both because tracking identifies gaps and because the follow-up contact itself reinforces the clinical message.

Minimum tracking:

A simple log (spreadsheet or EHR flag) capturing:

• Patient identifier
• Date of positive screen
• Date referral made
• Referral destination
• Confirmed appointment (yes/no, date)

Follow-up contact:

For patients with moderate-to-severe PMAD presentations (EPDS 13 and above), a brief follow-up call from an MA or care coordinator at 1 to 2 weeks post-referral confirms that the appointment was scheduled. For practices with sufficient staff, this call can also check in on symptom severity.

At subsequent visits:

Routinely asking "Did you connect with [therapist's name]?" at the next OB visit closes the tracking loop and signals to the patient that the referral was a real clinical recommendation, not an afterthought.

---

Step 7: Close the Referral Loop with the Receiving Provider

With a patient release of information in place, the receiving perinatal mental health practice can confirm to the referring OB when the patient has been seen and -- at significant milestones -- update the clinical picture. This is the collaborative care component.

At minimum: confirmation that the patient scheduled and attended. This takes one brief message or portal note and closes the referral loop.

For practices building closer collaborative care relationships with a perinatal mental health provider, standing communication protocols can be established: the therapist notifies the OB of any significant clinical changes, medication initiations, or level-of-care recommendations.

Implementation Checklist

• [ ] EPDS embedded in intake workflows for prenatal and postpartum visits
• [ ] Written protocol defining screening triggers and referral thresholds
• [ ] Specific perinatal mental health referral resource identified (PMH-C certified, telehealth, insurance-verified)
• [ ] Referral mechanism that can be completed in the office (form, phone, portal link)
• [ ] Staff training: MA/front desk know what to do with a positive screen
• [ ] Warm handoff protocol documented and practiced
• [ ] Referral tracking system in place (EHR flag or log)
• [ ] Follow-up protocol for moderate-to-severe positive screens
• [ ] Loop-closing mechanism with receiving provider

This checklist can be used to assess the current state of any OB practice's PMAD referral infrastructure and identify the specific gaps to close first.
