[Consultation liaison during the peripartum: Network care between liaison and mobile unit]

The pregnancy periods of peripartum and immediate postpartum represent moments of opportunity to access care. Both prevention and therapeutic management can be offered with a better chance of success during these periods. Our specific Consultation Liaison (CL) team PPUMMA was created in order to respond to the need for early detection of psychopathology and rapid implementation of therapeutic management and preventive measure for mother and child. The importance of urgently intervening "on site" seemed a necessity since duration of hospitalization in maternity wards is very short. Women might not know or understand their symptoms or be ready to ask for a referral for themselves but could be ready to respond positively to a team approach where the psychiatrist is part of the Ob-Gyn department. Working with an interdisciplinary approach tends to lower stress linked to the psychiatric side of the consultation and stigma related to psychological or psychiatric issues; therefore, PPUMMA intervenes within 48 to 72hours of birth. It deals with assessment and diagnosis during the peripartum period and orientation and referral for both mother and infant when necessary after birth. The Perinatal Psychiatry emergency mobile unit PPUMMA was created in order to address these issues.

From 2008 to 2015, 1907 patients were assessed but data were missing for 90 patients. We therefore analyzed 1817 patient files looking at age, diagnosis origin of referral, time of referral (pre or postpartum) and delay from referral to assessment.

Most patients were between 20 and 40 (81.5 %). One hundred and eighteen patients were under 20 years of age, of whom 64 were minors (3.5 %), and 218 were 40 or more (12 %). These two groups were over-represented close to threefold when comparing with national birth data records. A psychologist had first seen three out of four women. Midwives and Ob-Gyn referred 9 % and 8 % of patients while Social workers sent in 4 %. Two thirds of the women were seen during pregnancy, 50 % were seen the same day and 80 % received a consultation within 72hours. Three out of five of women had an assessment that concluded in a "Neurotic, stress-related and somatoform disorders" type code disorder linked to stress and somatoform disorder in ICD 10 (F40-F49). This is due to a high number (47.2 %) of F43 "Reaction to severe stress, and adjustment disorders". Twentynine present of women had a mood disorder (F30-39), and close to one third (31.6 %) had a personality disorder diagnosis attached. Schizophrenia, schizotypal and delusional disorders (F20-F29) represented 4.4 % of diagnoses. One third of the population had comorbid disorders: meeting either two (28.5 %) or three (3.7 %) diagnostic criteria for a psychiatric disorder. Most co-morbidity is due to personality disorder (82 % F60-F69).

The number of referrals and diagnostic criteria met show how essential a psychiatric CL team assessing and orienting women during pregnancy and immediate postpartum is. Opportunity for adaptation of treatment during the peripartum period and more long-term tailored management of disorders can be organized during this period in a multidisciplinary approach. Knowing how essential maternal mental health is for women, for infant development and for mother-infant interactions, this is a unique window for access to care and intervention. Maternal mental health is a public health issue. Access to psychiatric assessment and care during the peripartum period offers unique possibilities for prevention and care.
