Rationale
Perinatal mental health conditions (PMHC) are a leading overall and preventable cause of pregnancy-related morbidity and mortality. PMHC are the most common pregnancy complication, with data showing up to 1 and 5 perinatal individuals are affected. When not addressed, PMHC have been shown to lead to negative outcomes for the birthing people who are diagnosed with them, their offspring, families, and their communities.
It has been postulated that many obstetric care clinicians are not confident in addressing PMHC adequately as they were not trained in the full mental health care pathway including screening, assessment, timely initiation of evidence-based treatment, metric-based treatment titration, and follow-up to remission. It is our belief at PNQIN that in implementing these pathways using evidence-based care and a multidisciplinary quality-improvement focused approach, we can work to decrease the incidence and impact of PMHC at a local, state, and national level.
In practice, there are several documented improvements in management of PMHC following targeted quality improvement (QI) initiatives like the PMHC Bundle, in both outpatient and inpatient sites, across the country. A 2024 review of published accounts of PMHC-specific QI initiatives demonstrates that time and time again, there is an improvement in screening, referral, and treatment when projects are tackled in this manner.
This initiative aims to improve the identification and treatment of perinatal mental health conditions (PMHC) for all patients throughout the entire perinatal period. For the purposes of the bundle, PMHC includes: mood, anxiety, and anxiety-related disorders that occur during pregnancy or within one year of delivery, including conditions that may have started prior to conception.
For a full list of conditions, please review page 8 of the AIM PMHC ICD-10 codes list
How to Participate
We hope you will join us to collaborate, learn, and implement the best practices and tools for appropriate and timely identification and treatment of perinatal mental health conditions.
Answers to this survey allow PNQIN to gain better understanding of where you are in several key areas of perinatal mental health care, prior to bundle implementation at your institution.
Tell PNQIN about your progress and give us feedback on data collection, usefulness of resources, etc.
Present your work on this bundle implementation at a webinar or PNQIN Summit poster session.
Meet with PNQIN on the 3rd Tuesdays at 1pm starting in Sept 2024 to provide your input on statewide bundle implementation. Email PNQINAdmin@pnqinma.org to join.
