Postpartum psychosis: risk factors identification

The Pressing Need to Integrate Mental Health into Obstetric Care

Mental health and substance use conditions are prevalent among perinatal individuals. These conditions have a negative impact on the health of perinatal individuals, their infants, and families, yet are underdiagnosed and undertreated. Populations that have been marginalized disproportionately face barriers to accessing care. Integrating mental health into obstetric care could address the perinatal mental health crisis. We review perinatal mental health conditions and substance use, outline the impact associated with these conditions, and describe the promise and potential of integrating mental health into obstetric settings to improve outcomes for patients receiving obstetric and gynecologic care.

Predictive factors and treatment of postpartum mania: a representative case

Postpartum mania and psychosis puts both the person giving birth and their child at significant risk, so predicting its onset and determining effective treatment is crucial. Here, a representative case is presented of a patient started on an antidepressant during her pregnancy who suffered a postpartum manic episode with psychosis. The case describes many of the risk factors and treatment issues faced by clinicians when caring for patients with these symptoms in the postpartum period. Subsequent discussion provides guidance for clinicians to help predict postpartum mania and reviews factors that may increase the risk of its onset. The evidence for psychiatric treatment is also reviewed to both prevent and treat postpartum mania and psychosis.

Mapping high-risk clusters and identifying place-based risk factors of mental health burden in pregnancy

Purpose

Despite affecting up to 20% of women and being the leading cause of preventable deaths during the perinatal and postpartum period, maternal mental health conditions are chronically understudied. This study is the first to identify spatial patterns in perinatal mental health conditions, and relate these patterns to place-based social and environmental factors that drive cluster development.

Methods

We performed spatial clustering analysis of emergency department (ED) visits for perinatal mood and anxiety disorders (PMAD), severe mental illness (SMI), and maternal mental disorders of pregnancy (MDP) using the Poisson model in SatScan from 2016 to 2019 in North Carolina. Logistic regression was used to examine the association between patient and community-level factors and high-risk clusters.

Results

The most significant spatial clustering for all three outcomes was concentrated in smaller urban areas in the western, central piedmont, and coastal plains regions of the state, with odds ratios greater than 3 for some cluster locations. Individual factors (e.g., age, race, ethnicity) and contextual factors (e.g., racial and socioeconomic segregation, urbanity) were associated with high risk clusters.

Conclusions

Results provide important contextual and spatial information concerning at-risk populations with a high burden of maternal mental health disorders and can better inform targeted locations for the expansion of maternal mental health services.

Systematic review of the association between adverse life events and the onset and relapse of postpartum psychosis

Postpartum psychosis is defined as a psychotic episode occurring within 4 to 6  weeks of childbirth. While there is robust evidence that adverse life events are associated with the onset and relapse of psychosis outside the postpartum period, the extent to which these contribute to postpartum psychosis is less clear. This systematic review examined whether adverse life events are associated with an increased likelihood of developing postpartum psychosis or subsequent relapse in women diagnosed with postpartum psychosis. The following databases were searched from inception to June 2021: MEDLINE, EMBASE, PsycInfo. Study level data were extracted including setting, number of participants, type of adverse event, and differences between groups. A modified version of the Newcastle-Ottawa Quality Assessments Scale was used to assess risk of bias. In total, 1933 records were identified, of which 17 met the inclusion criteria, comprising nine case-control studies and eight cohort studies. Most studies (16/17) examined the association between adverse life events and the onset of postpartum psychosis, with only in which the outcome was relapse of psychosis. Overall, there were 63 different measures of adversity examined (most of which were examined in a single study only) and 87 associations between these measures and postpartum psychosis tested across the studies. In terms of statistically significant associations with onset/relapse of postpartum psychosis, 15 (17%) were positive (i.e., the adverse event increased the risk of onset/relapse), 4 (5%) were negative, and 68 (78%) were not statistically significant. Our review highlights the diversity of risk factors examined in this field, with few attempts at replication, hence limiting the ability to conclude that any single risk factor is robustly associated with the onset of postpartum psychosis. Further large-scale studies, that attempt to replicate earlier studies, are urgently needed to determine whether adverse life events play a role in the onset and exacerbation of postpartum psychosis.

Fleur G, Mukona L, Hernandez E, Lamberty N. Peripartum Complications as Risk Factors for Postpartum Psychosis: A Systemic Review

The aim of this research paper is to conduct a systematic review of periparturient complications as risk factors of postpartum psychosis. The investigation of risk factors for maternal psychosis following childbirth is complicated by the risk of confounding by a previous psychiatric history; therefore, this systematic review focuses on labor complications as risk factors among women without any previous psychiatric hospitalizations or diagnoses.

Articles were collected and analyzed from the PubMed, MEDLINE, and Cochrane Review Library databases, as well as Clinicaltrials.gov, in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Article abstracts and article titles of the identified publications were screened independently by all seven authors, and studies were selected if they met the following inclusion criteria: patients were diagnosed with postpartum psychosis per the guidelines in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-V), DSM-IV or World Health Organization’s ICD-10 Classification of Mental and Behavioral Disorders; patients presented with no prior psychiatric diagnoses, hospitalizations or history; and the study evaluated the association of periparturient complications to first-onset postpartum psychosis, excluding narrative reviews, systematic reviews, or meta-analyses.

Fifteen case-control, cohort, and case report studies, with thousands of patients, were selected to investigate the correlation between perinatal complications and first-onset post-partum psychosis. Obstetric complications during childbirth significantly predisposed for postpartum psychosis in certain individual studies but did not reveal an association in others.

More studies must be implemented to elaborate on this limited scope.

The Important Role of Partner Support in Women's Mental Disorders During the Perinatal Period. A Literature Review

The arrival of a newborn is often a happy event in a woman's life. However, many women experience perinatal distress such as anxiety disorders and depression during pregnancy or postpartum period. Although the positive interpersonal relationships of women with their wider environment seem to be a support network, research shows that support provided by partners is a very important protective factor in reducing mental health disorders in both prenatal and postnatal period in a woman's life. for this reason, more research needs to be done in the field of perinatal distress in order to clarify the causes that lead to mental disorders and to strengthen the partner's role in the management of perinatal mental disorders of women.

Postpartum Psychosis after Traumatic Cesarean Delivery

An emergency cesarean delivery can be a traumatic childbirth experience for a woman and a risk factor for postpartum psychosis, especially in a patient with a history of bipolar disorder. This article describes the case of a pregnant woman with an unknown history of bipolar disorder who developed an acute psychotic reaction during the procedure of an emergency caesarian section and switched to mania. The purpose of this case study is for perinatal health care professionals to identify suspicious symptoms and promptly refer to psychiatric services so as to ensure the mother's and the newborn's safety. This case study highlights the importance of assessing women with bipolar disorder or a previous psychotic episode for the risk of psychiatric complications in pregnancy and after childbirth. Midwifery education on perinatal mental health is crucial for the detection of suspicious symptoms and early referral to a specialist.

Phenomenology, Epidemiology and Aetiology of Postpartum Psychosis: A Review

Postpartum psychoses are a severe form of postnatal mood disorders, affecting 1–2 in every 1000 deliveries. These episodes typically present as acute mania or depression with psychosis within the first few weeks of childbirth, which, as life-threatening psychiatric emergencies, can have a significant adverse impact on the mother, baby and wider family. The nosological status of postpartum psychosis remains contentious; however, evidence indicates most episodes to be manifestations of bipolar disorder and a vulnerability to a puerperal trigger. While childbirth appears to be a potent trigger of severe mood disorders, the precise mechanisms by which postpartum psychosis occurs are poorly understood. This review examines the current evidence with respect to potential aetiology and childbirth-related triggers of postpartum psychosis. Findings to date have implicated neurobiological factors, such as hormones, immunological dysregulation, circadian rhythm disruption and genetics, to be important in the pathogenesis of this disorder. Prediction models, informed by prospective cohort studies of high-risk women, are required to identify those at greatest risk of postpartum psychosis.

Mother-to-Infant Bonding in Women with Postpartum Psychosis and Severe Postpartum Depression: A Clinical Cohort Study

Mother-to-infant bonding is important for long-term child development. The aim of this study was to investigate bonding in women admitted to a Mother and Baby Unit with postpartum depression (PD, n = 64) and postpartum psychosis (PP, n = 91). Participants completed the Postpartum Bonding Questionnaire (PBQ), the Edinburgh Postnatal Depression Scale (EPDS) and the Young Mania Rating Scale (YMRS) weekly during admission. At admission, 57.1% of women with PD had impaired bonding, compared to only 17.6% of women with PP (p-value < 0.001). At discharge, only 18.2% of women with PD and 5.9% of women with PP still experienced impaired bonding (p-value = 0.02). There was a strong association between decrease of depressive and manic symptoms and improved bonding over an eight-week admission period. In a small group of women (5.7%) impaired bonding persisted despite being in remission of their psychiatric disorder. The results from our study show that impaired bonding is a more present and evidently severe problem in postpartum depression but not so much in postpartum psychosis. Treatment of depressive symptoms will improve bonding in almost all women, but clinicians should assess if impaired bonding is still present after remission because for a small group special care and treatment focused on bonding might be required.

Prevalence of maternal psychological disorders after immediate postpartum haemorrhage: a repeated cross-sectional study - the PSYCHE* study protoco

INTRODUCTION

The main objective of this study is to assess the prevalence of depression at 2, 6 and 12 months postpartum in women who have had an immediate postpartum haemorrhage (PPH) (blood loss ≥500 mL within 24 hours of delivery). The secondary objectives are to assess the prevalence of anxiety and post-traumatic stress disorder among these women and to evaluate the prevalence of psychological disorders according to the severity of the PPH.

METHODS AND ANALYSIS

This repeated, cross-sectional, single-centre study will take place at the Clermont-Ferrand University Hospital (France). The population will comprise a cohort of women giving birth at a term ≥22 weeks of gestation.For each woman with a PPH (exposed), two women without PPH (unexposed) will be included: the women who give birth immediately before and immediately after her. The PPH will be managed according to French guidelines. The principal endpoint is the prevalence of depression, measured by the Edinburgh Postnatal Depression Scale (EPDS). The intervention will consist of four surveys including various self-completed questionnaires: the first during the immediate postpartum (Post-Delivery Perceived Stress Inventory (PDPSI), Spielberger'sState-Trait Anxiety Inventory (STAI)-Y-A and Y-B and Mini-International Neuropsychiatric Interview (M.I.N.I.) 5.0.0), then at 2 months (EPDS, STAI-Y-A, Generalised Anxiety Disorder (GAD-7) and Revised Impact of Event Scale (IES-R)), and finally at 6 months and 1 year postpartum (EPDS, STAI-Y-A, GAD-7, M.I.N.I. 5.0.0 and IES-R). The study will include 1542 women - 514 with PPH.

ETHICS AND DISSEMINATION

The institutional review board (IRB) approved the study on 14 February 2017 (IRB Sud Est VI: N°AU1243).Results will be reported in peer-reviewed journals and at scientific meetings. Findings from the study will be useful for individualising medical follow-up after childbirth, especially for woman who experienced a PPH, but also more generally in increasing birth professionals' awareness of effects of trauma. The evidence obtained might also lead to modifying practices and including this recommendation in French guidelines on PPH.

Postpartum psychosis in a non-native language-speaking patient: A perspective on language barriers and cultural competency

Postpartum psychosis is a condition characterised by rapid onset of psychotic symptoms several weeks after childbirth. Outside of its timing and descriptions of psychotic features, minimal research exists due to its relative rarity (1 to 2 per 1000 births in the USA), with greater emphasis on postpartum sadness and depression. With the existing literature, cultural differences and language barriers previously have not been taken into consideration as there are no documented cases of postpartum psychosis in a non–English-speaking patient. Correctly differentiating postpartum psychosis from other postpartum psychiatric disorders requires adeptly evaluating for the presence of psychotic symptoms with in-depth history taking. Here, we present a case of postpartum psychosis in a Japanese-speaking only patient, with an associated clinical course and culturally appropriate approach to treatment. A review of postpartum psychosis and language/cultural considerations are also discussed, with attention on the Japanese concept of ‘Satogaeri bunben’.

Postpartum mental health service utilization in women with Human Immunodeficiency Virus (HIV): a population-based study

Women with HIV have higher rates of psychiatric disorders than HIV-negative women, yet little is known about their postpartum mental health and associated service use. The purpose of this study was to characterize HIV-positive women's use of ambulatory and acute mental health services in the first year postpartum, relative to HIV-negative women. Using health administrative data, we identified 861,365 women who had a live birth delivery from April 1, 2002 to March 31, 2012 in Ontario, Canada, of whom 530 were identified to be HIV-positive. We described their use of mental health services, including outpatient mental health visits, psychiatric emergency department (ED) visits and hospitalizations using adjusted odds ratios (aORs) and 95% confidence intervals (CIs). HIV-positive women were more likely to access outpatient mental health services (31.5% vs. 21.0%, aOR, 1.26; 95% CI, 1.03-1.55), but more likely to remain engaged in psychiatrist services only (15.6% vs. 6.5%, aOR, 2.35; 95% CI, 1.41-3.72). They were also more likely to require a psychiatric ED visit or hospitalization (3.3% vs. 1.1%, aOR, 2.74; 95% CI, 1.72-4.12). Our findings highlight the importance of considering postpartum mental health as part of comprehensive reproductive health care for women with HIV.

Delusional ideation during the perinatal period in a community sample

BACKGROUND

Despite the prevalence of mental health problems during the perinatal period, little research has examined psychotic symptoms in a community sample across pregnancy and the postpartum. Exposure to environmental risk factors, and immigration in particular, are associated with increased risk for psychotic disorders. The current investigation examined whether psychosocial risk and immigrant status would predict levels of delusional ideation across the perinatal period when controlling for depression, anxiety, and demographic factors.

METHODS

A community sample of 316 pregnant women was assessed at 12-14 and 32-34weeks gestation during routine clinic visits, and at 7-9weeks postpartum during a home visit. Measures included self-report ratings of psychosocial risk (e.g., history of mental health problems or abuse, stressful life events, lack of social support), pregnancy-related anxiety, depressive symptomatology, and delusional ideation.

RESULTS

There was less delusional ideation during the postpartum period than during early pregnancy. Across all time points, levels of delusional ideation were lower than in the general population. Analyses using multilevel modeling indicated significant fixed-effects for the variables time, age, partnership, being religious and prenatal anxiety, but not depressive symptomatology, on delusional ideation. Immigrant status moderated the effect of psychosocial risk such that greater psychosocial risk predicted more symptoms of delusional ideation among immigrants, but not non-immigrants.

CONCLUSION

Psychosocial risk factors place immigrant women at an increased likelihood for experiencing delusional ideation during the perinatal period.

Admission to psychiatric hospital in the early and late postpartum periods: Scottish national linkage study

OBJECTIVE

To describe weekly admission rates for affective and non-affective psychosis, major depression and other psychiatric disorders in the early and late postpartum periods. To assess the impact of socioeconomic status, age and parity on admission rates.

METHODS

Scottish maternity records were linked to psychiatric hospital admissions. 3290 pregnancy-related psychiatric admissions were assessed. Weekly admission rates were calculated for the pregnancy period, early postpartum period (6 weeks after birth) and late postpartum period (up to 2 years after birth), and compared with pre-pregnancy rates (up to 2 years before pregnancy). Admission rates were generated by calculating the total number of admissions for each time period divided by the number of weeks in the period. Incidence rate ratios (IRRs) were generated for each time period, using deprivation, age, parity and record of previous psychiatric hospital care-adjusted Poisson regression models.

RESULTS

Women from more deprived social quintiles accounted for the largest proportion of admissions across all time periods. Compared with pre-pregnancy period, admission rates fell during pregnancy, increased markedly during the early postpartum period, and remained elevated for 2 years after childbirth. Within the most affluent quintile, admission IRRs were higher in the early postpartum period (IRR=1.29, 95% CI 1.02 to 1.59) than in the late postpartum period (IRR=0.87, 95% CI 0.74 to 0.98). For the late postpartum period, there was a positive association between higher maternal age and admission IRRs (ages 20-35 years, IRR=1.35, 95% CI 1.16 to 1.54 and age>40 years IRR=1.72, 95% CI 1.41 to 2.09).

CONCLUSIONS

Rates of psychiatric admission fell during pregnancy and increased in the early postpartum period (particularly during the first 2 weeks after birth), and remained elevated above baseline during the 2-year late postpartum period. An understanding of how social deprivation, age and parity might influence risk of psychiatric admission at different time points could help to target perinatal mental health services more effectively.

Postnatal depression among women availing maternal health services in a rural hospital in South India

BACKGROUND AND OBJECTIVE

Postnatal depression, with an estimated prevalence of 13-19%, causes significant impairment of mental health among women worldwide and has long term consequences. However, more than half of all cases are not detected by healthcare providers. Screening for postnatal depression has not been given importance in maternal health programs in India. Our objective was to screen for postnatal depression among women attending a rural hospital in India, immediately postpartum and at 6-8 weeks post-delivery, and to study associated factors.

METHODS

A cross sectional study was done on 123 postnatal women attending a rural maternity hospital in Karnataka, South India, of whom 74 women were interviewed within one week of childbirth, and 49 women at 6-8 weeks post-delivery. The Edinburgh Postnatal Depression Scale was used to screen for postnatal depression.

RESULTS

About 45.5% of the women screened positive for postnatal depression (44.6% of all subjects within one week of delivery and 46.9% at 6-8 weeks after delivery). Postnatal depression was significantly associated with mood swings during antenatal period, staying with the family of birth during pregnancy and away from their husbands, and was significantly higher among women who perceived their life as stressful and having a low self-esteem (P<0.05).

CONCLUSIONS

This study found a high prevalence of postnatal depression in women in rural Karnataka. This underlines the need for incorporating screening for postnatal depression in the routine care of women during pregnancy and delivery.
