Association between stillbirth ≥23 weeks gestation and acute psychiatric illness within 1 year of delivery

Is severe maternal morbidity a risk factor for postpartum hospitalization with mental health or substance use disorder diagnoses? Findings from a retrospective cohort study in Maryland: 2016-2019

BACKGROUND

Perinatal mental health conditions and substance use are leading causes, often co-occurring, of pregnancy-related and pregnancy-associated deaths in the United States. This study compares odds of hospitalization with a mental health condition or substance use disorder or both during the first year postpartum between patients with and without severe maternal morbidity (SMM) during delivery hospitalization.

METHODS

Data are from the Maryland's State Inpatient Database and include patients with a delivery hospitalization during 2016-2018 (n = 197,749). We compare rate of hospitalization with a mental health condition or substance use disorder or both at 42 days and 43 days to 1 year postpartum by occurrence of SMM during the delivery hospitalization. We use multivariable logistic regression to derive the odds of hospitalization with each outcome for patients by SMM status, adjusted for patient sociodemographic characteristics, presence of mental health condition or substance use disorder diagnoses during the delivery hospitalization, and delivery outcome. All SMM, mental health conditions, and substance use disorders are identified using ICD-10 diagnosis and procedure codes.

RESULTS

Overall, 5,793 patients (2.9%) who delivered during 2016-2018 experienced hospitalization in the year following delivery. Among these patients, 24.3% (n = 1,410) had a mental health condition diagnosis, 10.6% (n = 619) had a substance use disorder diagnosis, and 9.8% (n = 570) had co-occurring mental health condition and substance use disorder diagnoses. Patients with SMM had 3.7 times the adjusted odds (95% CI 2.7, 5.2) of hospitalization with a mental health condition diagnosis, 2.7 times the odds (95% CI 1.6, 4.4) of a hospitalization with substance use disorder diagnosis, and 3.0 times the odds (95% CI 1.8, 4.8) of hospitalization with co-occurring mental health condition and substance use disorder diagnoses during the first-year postpartum.

CONCLUSION

Patients who experience SMM during their delivery hospitalization had higher odds of hospitalization with a mental health condition, substance use disorder, and co-occurring mental health condition and substance use disorder in the one-year postpartum period. Treatment and support resources for mental health and substance use providers --including enhanced screening and personal introduction of providers -- should be made available to patients with SMM upon discharge after delivery, and evidence-based interventions to improve mental health and reduce substance use should be prioritized in these patients.

Association of General Anesthesia for Cesarean Delivery with Postpartum Depression and Suicidality

BACKGROUND

Compared to neuraxial anesthesia, general anesthesia (GA) for cesarean delivery is associated with an increased risk of postpartum depression (PPD) requiring hospitalization. However, obstetric complications occurring during childbirth (eg, stillbirth) are associated with both increased use of GA and increased risk of PPD, and may account for the reported association between GA and PPD. This study assessed the association of GA for cesarean delivery with PPD requiring hospitalization, outpatient visit, or emergency department (ED) visit, accounting for obstetric complications.

METHODS

This retrospective cohort study included women who underwent a cesarean delivery in New York State between January 2009 and December 2017. Women were followed for 1 year after discharge for readmission, outpatient visit, or ED visit. The primary outcome was PPD requiring readmission, outpatient visit, or ED visit. The 2 secondary outcomes were (1) PPD requiring readmission, and (2) suicidality. Obstetric complications included severe maternal morbidity, blood transfusion, postpartum hemorrhage, preterm birth, and stillbirth. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of PPD, PPD requiring readmission, and suicidality associated with GA were estimated using the propensity score matching and the overlap propensity score weighting methods.

RESULTS

Of the 325,840 women included, 19,513 received GA (6.0%; 95% CI, 5.9-6.1). Complications occurred in 43,432 women (13.3%) and the GA rate for these women was 9.7% (95% CI, 9.4-10.0). The incidence rate of PPD was 12.8 per 1000 person-years, with 24.5% requiring hospital readmission, and was higher when an obstetric complication occurred (17.1 per 1000 person-years). After matching, the incidence rate of PPD was 15.5 per 1000 person-years for women who received neuraxial anesthesia and 17.5 per 1000 person-years for women who received GA, yielding an aHR of 1.12 (95% CI, 0.97-1.30). Use of GA was associated with a 38% increased risk of PPD requiring hospitalization (aHR: 1.38; 95% CI, 1.07-1.77) and with a 45% increased risk of suicidality (aHR 1.45; 95% CI, 1.02-2.05). Results were consistent when using the overlap propensity score weighting.

CONCLUSIONS

Use of GA for cesarean delivery is independently associated with a significantly increased risk of PPD requiring hospitalization and suicidality. It underscores the need to avoid using GA whenever appropriate and to address the potential mental health issues of patients after GA use, specifically by screening for PPD and providing referrals to accessible mental health providers as needed.

Postpartum readmission risk: a comparison between stillbirths and live births

BACKGROUND

Stillbirth occurs more commonly among pregnant people with comorbid conditions and obstetrical complications. Stillbirth also independently increases maternal morbidity and imparts a psychosocial hazard when compared with live birth. These distinct needs and burden may increase the risk for postpartum readmission after stillbirth.

OBJECTIVE

This study aimed to examine the risk for maternal postpartum readmission after stillbirth in comparison with live birth and to identify indications for readmission and the associated risk factors.

STUDY DESIGN

This was a retrospective cohort of patients with singleton stillbirths or live births, delivered at ≥20 weeks' gestation, who were identified from the 2019 Nationwide Readmissions Database. The primary outcome was all-cause readmission within 6 weeks of discharge from the childbirth hospitalization. The association between stillbirth (vs live birth) and risk for readmission was assessed using multivariable regression models with adjustment for maternal age, sociodemographic characteristics, maternal and obstetrical conditions, and delivery characteristics. Within the stillbirth group, risk factors for readmission were further examined using multivariable regression. The secondary outcomes included principal indication for readmission (categorized based on principal diagnosis code of the readmission hospitalization) and timing of readmission (number of weeks after childbirth hospitalization). Differences in these secondary outcomes were compared between the stillbirth and live birth groups using chi-square tests. All analyses accounted for the complex sample design to generate nationally representative estimates.

RESULTS

Postpartum readmission occurred in 2.7% of 16,636 patients with stillbirths, whereas it occurred in 1.6% of 2,870,677 patients with live births (unadjusted risk ratio, 1.65; 95% confidence interval, 1.47-1.86). The higher risk for readmission after stillbirth (vs live birth) persisted after adjusting for maternal, obstetrical, and delivery characteristics (adjusted risk ratio, 1.27; 95% confidence interval, 1.11-1.46). The distribution of principal indication for readmission differed after stillbirth and after live birth and included hypertension (30.2% vs 39.5%; unadjusted risk ratio, 0.76; 95% confidence interval, 0.63-0.93), mental health or substance use disorders (6.8% vs 3.6%; unadjusted risk ratio, 1.90; 95% confidence interval, 1.15-3.16), and venous thromboembolism (5.8% vs 2.0%; unadjusted risk ratio, 2.87; 95% confidence interval, 1.60-5.17). Among patients with stillbirths, 56.0% of readmissions occurred within 1 week, 71.8% within 2 weeks, and 88.1% within 4 weeks; the timing of readmission did not differ significantly between the stillbirth and live birth cohorts. Pregestational diabetes (adjusted risk ratio, 1.87; 95% confidence interval, 1.20-2.93), gestational diabetes (adjusted risk ratio, 1.67; 95% confidence interval, 1.03-2.71), hypertensive disorders of pregnancy (adjusted risk ratio, 1.80; 95% confidence interval, 1.31-2.47), obesity (adjusted risk ratio, 1.46; 95% confidence interval, 1.01-2.12), and primary cesarean delivery (adjusted risk ratio, 1.74; 95% confidence interval, 1.17-2.58) were associated with a higher risk for readmission after stillbirth, whereas higher household income was associated with a lower risk for readmission (eg, adjusted risk ratio for income ≥$82,000 vs $1-$47,999, 0.48; 95% confidence interval, 0.30-0.77).

CONCLUSION

When compared with live births, the risk for postpartum readmission was higher after stillbirths, even after adjustment for differences in the patient demographic and clinical characteristics. Readmission for mental health or substance use disorders and venous thromboembolism is more common after stillbirths than after live births.

Is severe maternal morbidity a risk factor for postpartum hospitalization with mental health or substance use disorder diagnoses? Findings from a retrospective cohort study in Maryland: 2016-2019

BACKGROUND

Perinatal mental health conditions and substance use are leading causes, often co-occurring, of pregnancy-related and pregnancy-associated deaths in the United States. This study compares odds of hospitalization with a mental health condition or substance use disorder or both during the first year postpartum between patients with and without severe maternal morbidity (SMM) during delivery hospitalization.

Methods

Data are from the Maryland's State Inpatient Database and include patients with a delivery hospitalization during 2016-2018 (n = 197,749). We compare rate of hospitalization with a mental health condition or substance use disorder or both at 42 days and 42 days to 1 year postpartum by occurrence of SMM during the delivery hospitalization. We use multivariable logistic regression to derive the odds of hospitalization with each outcome for patients by SMM status, adjusted for patient sociodemographic characteristics, presence of mental health condition or substance use disorder diagnoses during the delivery hospitalization, and delivery outcome. SMM, mental health conditions, and substance use disorders are identified using ICD-10 diagnosis and procedure codes.

RESULTS

Overall, 5,793 patients (2.9%) who delivered during 2016-2018 experienced hospitalization in the year following delivery. Among these patients, 24.3% (n = 1,410) had a mental health condition diagnosis, 10.6% (n = 619) had a substance use disorder diagnosis, and 9.8% (n = 570) had co-occurring mental health condition and substance use disorder diagnoses. Patients with SMM had 3.7 times the odds (95% CI 2.7, 5.2) of hospitalization with a mental health condition diagnosis, 2.7 times the odds (95% CI 1.6, 4.4) of a hospitalization with substance use disorder diagnosis, and 3.0 times the odds (95% CI 1.8, 4.8) of hospitalization with co-occurring mental health condition and substance use disorder diagnoses during the first-year postpartum adjusting for covariates.

CONCLUSION

Patients who experience SMM during their delivery hospitalization had higher odds of hospitalization with a mental health condition, substance use disorder, and co-occurring mental health condition and substance use disorder in the one-year postpartum period. Treatment and support resources for mental health and substance use providers --including enhanced screening and warm handoffs -- should be made available to patients with SMM upon discharge after delivery, and evidence-based interventions to improve mental health and reduce substance use should be prioritized in these patients.

Associations between pregnancy loss and common mental disorders in women: a large prospective cohort study

Background

Increasing evidence suggests that pregnancy loss can lead to negative emotional outcomes, such as anxiety and depression, for women. However, limited knowledge exists regarding the long-term risk of mental disorders among individuals who have experienced pregnancy loss.

Objective

To investigate the associations between pregnancy loss and the risk of common mental disorders.

Methods

In the UK Biobank, a total of 218,990 women without any mental disorder at baseline were enrolled between 2006 and 2010 and followed until October 2022. Information on the history of pregnancy loss was obtained through self-reported questionnaires at baseline. Cox proportional hazard regression models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between pregnancy loss and common mental disorders.

Results

During a median follow-up time of 13.36 years, there were 26,930 incident cases of common mental disorders. Incidence rates of common mental disorders were elevated among women with a history of stillbirth (HR 1.15, 95% CI: 1.07-1.23), miscarriage (HR 1.06, 95% CI: 1.02-1.10), or pregnancy termination (HR 1.21, 95% CI: 1.17-1.25) compared to those without such experiences. Furthermore, the risk of common mental disorders significantly increased in women with two or more miscarriages (HR 1.14, 95% CI: 1.08-1.19) or two or more pregnancy terminations (HR 1.39, 95% CI: 1.30-1.48).

Conclusions

Pregnancy loss is associated with an increased risk of common mental disorders in women later in life. These findings may contribute to the enhancement of long-term monitoring and prevention of common mental disorders for women with such a history.

Call for Improved Fourth Trimester Care After Stillbirth

Women who experience stillbirths are at increased risk for severe maternal morbidity and mortality, which makes the postpartum period a critical time in which to address health conditions and prevent complications. However, research on the health care needs of women who experience stillbirths is scarce, and these women are often excluded from research on the postpartum period. Therefore, the purpose of this commentary is to identify gaps in the research on postpartum care after stillbirth, explain why current fourth trimester care guidelines in the United States are inadequate, and advocate for nursing research and practice to improve understanding of health care needs in the fourth trimester.

Postpartum Psychosis: A Review of Risk Factors, Clinical Picture, Management, Prevention, and Psychosocial Determinants

Postpartum psychosis is rare, but is a serious clinical and social problem. On its own, it is not included in DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) or ICD-10 (International Statistical Classification of Diseases and Related Health Problems) as a disease entity, and current diagnostic criteria equate it with other psychoses. This poses a serious legal problem and makes it difficult to classify. The disorder is caused by a complex combination of biological, environmental, and cultural factors. The exact pathophysiological mechanisms of postpartum psychosis remain very poorly understood. There is a need for further research and increased knowledge of the medical sector in the prevention and early detection of psychosis to prevent stigmatization of female patients during a psychiatric episode. It is necessary to regulate its position in the DSM5 and ICD-10. Attention should be paid to the social education of expectant mothers and their families. This article aims to review the current status of risk factors, prevention, and management of postpartum psychosis.

No Baby to Bring Home: Perinatal Loss, Infertility, and Mental Illness-Overview and Recommendations for Care

PURPOSE OF REVIEW

Update readers on the state of the research on mental health, perinatal loss, and infertility with a focus on providing a comprehensive overview to empower clinicians in treating this population.

RECENT FINDINGS

Rates of psychiatric illness are increased in people that experience perinatal loss and infertility. The research remains largely below the clear need for focused screening, prevention, and treatment. Clinicians and researchers need to remain attuned to the impact of perinatal loss and infertility on the mental health of patients and families. Screening, referral, and expanded therapeutic and psychiatric resources are imperative to improving the well-being of these patients and families.

Psychopathology Present in Women after Miscarriage or Perinatal Loss: A Systematic Review

Miscarriage or perinatal loss constitutes one of the most important emotional stressors a woman can experience and can be associated with bereavement. This mourning is a way of adapting and coping with the circumstances. However, inadequate management of this process can lead to the development of complicated grief and psychopathologies such as anxiety, depression, and post-traumatic stress disorder. The aim of this systematic review was to evaluate the prevalence of psychopathology (anxiety, depression, and post-traumatic stress disorder) in women with a history of miscarriage or perinatal loss in the year prior, and to compare these results with women without this history. A peer review was conducted in PubMed, Cochrane, Scopus, and Web of Science databases. We included (1) articles that included women of any age who had had a miscarriage or perinatal loss in the year prior, and (2) articles with a longitudinal cohort design with a comparison group of women without a history of miscarriage or perinatal loss. After the screening process, three articles met these inclusion criteria and were included in this study. Psychopathology in women after miscarriage or perinatal loss was higher than in the control groups. In addition, it was observed that these psychopathologies gradually decreased over the first year from the loss. In conclusion, abortion and perinatal loss pose a risk factor for the development of psychopathology. Therefore, we emphasize the importance of implementing a mental health plan for these women.

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.

Association Between Periviable Delivery and New Onset of or Exacerbation of Existing Mental Health Disorders

OBJECTIVE

To evaluate whether there is an association between periviable delivery and new onset of or exacerbation of existing mental health disorders within 12 months postpartum.

METHODS

We conducted a retrospective cohort study of individuals with liveborn singleton neonates delivered at 22 or more weeks of gestation from 2008 to 2017 in the MarketScan Commercial Research Database. The exposure was periviable delivery , defined as delivery from 22 0/7 through 25 6/7 weeks of gestation. The primary outcome was a mental health morbidity composite of one or more of the following: emergency department encounter associated with depression, anxiety, psychosis, posttraumatic stress disorder, adjustment disorder, self-harm, or suicide; new psychotropic medication prescription; new behavioral therapy visit; and inpatient psychiatry admission in the 12 months postdelivery. Secondary outcomes included components of the primary composite. Those with and without periviable delivery were compared using multivariable logistic regression adjusted for clinically relevant covariates, with results reported as adjusted incident rate ratios (aIRRs). Effect modification by history of mental health diagnoses was assessed. Incidence of the primary outcome by 90-day intervals postdelivery was assessed.

RESULTS

Of 2,300,244 included deliveries, 16,275 (0.7%) were periviable. Individuals with periviable delivery were more likely to have a chronic health condition, to have undergone cesarean delivery, and to have experienced severe maternal morbidity. Periviable delivery was associated with a modestly increased risk of the primary composite outcome, occurring in 13.8% of individuals with periviable delivery and 11.0% of individuals without periviable delivery (aIRR 1.18, 95% CI 1.12-1.24). The highest-risk period for the composite primary outcome was the first 90 days in those with periviable delivery compared with those without periviable delivery (51.6% vs 42.4%; incident rate ratio 1.56, 95% CI 1.47-1.66).

CONCLUSION

Periviable delivery was associated with a modestly increased risk of mental health morbidity in the 12 months postpartum.

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.

Association of Perceived Lack of Paternal Support After Stillbirth With Maternal Postpartum Depression or Anxiety

This cross-sectional study examines the incidence of postpartum depression and anxiety in women who perceive a lack paternal support after stillbirth.

The mental health impact of perinatal loss: A systematic review and meta-analysis

Perinatal loss can pose a significant risk to maternal mental health. There is limited data on the strength of association between perinatal loss and subsequent common mental health disorders (CMHD) such as anxiety, depression and post-traumatic symptoms (PTS). A systematic review and meta-analysis identified studies with control groups, published between January 1995 and March 2020 reporting validated mental health outcomes following perinatal loss. We identified 29 studies from 17 countries, representing a perinatal loss sample (n = 31,072) and a control group of women not experiencing loss (n = 1,261,517). We compared the likelihood of increased CMHD in both groups. Random-effects modelling on suggested that compared to controls, perinatal loss was associated with increased risk of depressive (RR = 2.14, 95% CI = 1.73-2.66, p < 0.001, k = 22) and anxiety disorders (RR = 1.75, 95% CI = 1.27-2.42, p < 0.001, k = 9). Compared to controls, Perinatal loss was also associated with increased depression (SMD = 0.34, 95% CI = 0.20-0.48, p < 0.001, k = 12) and anxiety scores (SMD = 0.35, 95% CI = 0.12-0.58, p < 0.003, k = 10). There were no significant effects for post-traumatic stress (PTS) outcomes (k = 3). Our findings confirm that anxiety and depression levels following perinatal loss are significantly elevated compared to "no loss" controls (live-births, non pregnant from community, or difficult live births). Elevated depression and anxiety rates were also reported for those who experienced loss during later stages of pregnancy. Assessing mental health following loss is a maternal health priority.

Suicide and Maternal Mortality

PURPOSE OF REVIEW

Suicide is a leading cause of death in the perinatal period (pregnancy and 1 year postpartum). We review recent findings on prevalence, risk factors, outcomes, and prevention and intervention for suicide during pregnancy and the first year postpartum.

RECENT FINDINGS

Standardization of definitions and ascertainment of maternal deaths have improved identification of perinatal deaths by suicide and risk factors for perinatal suicide. Reports of a protective effect of pregnancy and postpartum on suicide risk may be inflated. Clinicians must be vigilant for risk of suicide among their perinatal patients, especially those with mental health diagnoses or prior suicide attempts. Pregnancy and the year postpartum are a time of increased access to healthcare for many, offering many opportunities to identify and intervene for suicide risk. Universal screening for suicide as part of assessment of depression and anxiety along with improved access to mental health treatments can reduce risk of perinatal suicide.

Depression, anxiety, PTSD, and OCD after stillbirth: a systematic review

BACKGROUND

This systematic review aimed to provide an updated summary of studies investigating depression, anxiety, post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD) in parents after stillbirth (from 20 weeks gestational age until birth).

METHODS

A literature search was conducted in the databases Web of Science and PsychINFO. Main inclusion criteria were 1) peer-reviewed, quantitative, English-language articles published from 1980; (2) studies investigating depression, anxiety, PTSD, or OCD among parents following stillbirth; and (3) studies defining stillbirth as equal to or after 20 weeks of gestation.

RESULTS

Thirteen quantitative, peer-reviewed articles were eligible for inclusion. Selected articles investigated depression, anxiety, and PTSD, while no studies on OCD met our inclusion criteria. The majority of studies investigated women, while only two studies included men. The results indicated heightened short- and long-term levels of depression, anxiety, and PTSD in parents after stillbirth compared to those of parents with live birth. Studies investigating predictors found that social support, marital status, negative appraisals, and variables related to care and management after stillbirth affected levels of symptoms.

CONCLUSIONS

Parents who experience stillbirth have a considerably higher risk of reporting symptoms of depression, anxiety, and PTSD compared with parents with live births. More longitudinal studies are needed to increase our knowledge of how symptoms develop over time, and more research on fathers, transgender, non-binary and gender fluid individuals is needed. Research on the association between stillbirth and OCD is also warranted. Knowledge of the severity of anxiety, depression, and PTSD after stillbirth, and predictors associated with symptom severity could provide healthcare professionals with valuable information on how to provide beneficial postpartum care.

Maternal Health after Stillbirth: Postpartum Hospital Readmission in California

OBJECTIVE

The aim of this study is to assess whether the risk of postpartum readmission within 6 weeks of giving birth differs for women who had stillbirths compared with live births.

STUDY DESIGN

Using data from the Office of Statewide Health Planning and Development in California, we performed a population-based cohort study of 7,398,640 births between 1999 and 2011. We identified diagnoses and procedures associated with the first postpartum hospital readmission that occurred within 6 weeks after giving birth. We used log-binomial models to estimate relative risk (RR) of postpartum readmission for women who had stillbirth compared with live birth deliveries, adjusting for maternal demographic, prepregnancy, pregnancy, and delivery characteristics.

RESULTS

The rate of postpartum readmission was higher among women who had stillbirths compared with women who had live births (206 and 96 per 10,000 births, respectively). After adjusting for maternal demographic and medical characteristics, the risk of postpartum readmission for women who had stillbirths was nearly 1.5 times greater (adjusted RR = 1.47, 95% confidence interval: 1.35-1.60) compared with live births. Among women with stillbirths, the most common indications at readmission were uterine infection or pelvic inflammatory disease, psychiatric conditions, hypertensive disorder, and urinary tract infection.

CONCLUSION

Based on our findings, women who have stillbirths are at higher risk of postpartum readmissions within 6 weeks of giving birth than women who have live births. Women who have stillbirths may benefit from additional monitoring and counseling after hospital discharge for potential postpartum medical and psychiatric complications.

KEY POINTS

· Women who have stillbirths are at nearly 1.5 times greater risk of postpartum readmission than women who have live births.. · Uterine infections and pelvic inflammatory disease, and psychiatric conditions are the most common reasons for readmission among women who had a stillbirth.. · Women who have stillbirths may benefit from additional monitoring and counseling after hospital discharge for potential postpartum medical and psychiatric complications..

The unheard parental cry of a stillbirth: fathers and mothers

PURPOSE

Our objective was to compare the prevalence of depression, anxiety, stress, and domestic violence among parents after a stillbirth vs. livebirths and assessing of the need for psychological and pharmacological interventions for the affected individuals.

METHODS

This was a prospective cohort study conducted in a tertiary care public sector hospital Northern India. 150 consecutive couples with a recent stillbirth (group 1) and 150 couples with a recent live birth (group 2) were enrolled. They were screened for depression (EPDS scale), anxiety (GAD-7), stress (PSS). Apriori sample size was calculated. Screen positive mothers and fathers were compared for the presence of depression, anxiety and stress, domestic violence, and need for treatment interventions.

RESULTS

Depression was higher in group 1 mothers (39.3 vs 14.0%, p < 0.001) as well as fathers (18.1 vs 6.7%, p value = 0.022). Anxiety and moderate to severe stress were also significantly higher in stillborn than liveborn groups respectively. Characteristics associated with higher risk are analyzed. Domestic violence was found in 6.7% in group 1 and 2.7% in group 2 mothers (p value 0.169). Pharmacotherapy and counselling were required by 11.3 and 18.0% in stillbirth versus 3.3 and 18.7% in livebirth group, respectively.

CONCLUSION

Couples suffering stillbirths are at higher risk of depression, anxiety, and stress. We highlight this obstetrical public health issue, especially for the low middle income countries (LMIC) and advocate development of health policies for mental health screening of couples suffering stillbirths.

Risk factors for postpartum readmission among women after having a stillbirth

BACKGROUND

Compared to women with a live birth, women with a stillbirth are more likely to have maternal complications during pregnancy and at birth, but risk factors related to their postpartum health are uncertain.

OBJECTIVE

This study aimed to identify patient-level risk factors for postpartum hospital readmission among women after having a stillbirth.

STUDY DESIGN

This was a population-based cohort study of 29,654 women with a stillbirth in California from 1997 to 2011. Using logistic regression models, we examined the association of maternal patient-level factors with postpartum readmission among women after a stillbirth within 6 weeks of hospital discharge and between 6 weeks and 9 months after delivery.

RESULTS

Within 6 weeks after a stillbirth, 642 women (2.2%) had a postpartum readmission. Risk factors for postpartum readmission after a stillbirth were severe maternal morbidity excluding transfusion (adjusted odds ratio, 3.02; 95% confidence interval, 2.28-4.00), transfusion at delivery but no other indication of severe maternal morbidity (adjusted odds ratio, 1.95; 95% confidence interval, 1.35-2.81), gestational hypertension or preeclampsia (adjusted odds ratio, 1.93; 95% confidence interval, 1.54-2.42), prepregnancy hypertension (adjusted odds ratio, 1.80; 95% confidence interval, 1.36-2.37), diabetes mellitus (adjusted odds ratio, 1.78; 95% confidence interval, 1.33-2.37), antenatal hospitalization (adjusted odds ratio, 1.78; 95% confidence interval, 1.43-2.21), cesarean delivery (adjusted odds ratio, 1.73; 95% confidence interval, 1.43-2.21), long length of stay in the hospital after delivery (>2 days for vaginal delivery and >4 days for cesarean delivery) (adjusted odds ratio, 1.59; 95% confidence interval, 1.33-1.89), non-Hispanic black race and ethnicity (adjusted odds ratio, 1.38; 95% confidence interval, 1.08-1.76), and having less than a high school education (adjusted odds ratio, 1.35; 95% confidence interval, 1.02-1.80). From 6 weeks to 9 months, 1169 women (3.90%) had a postpartum readmission; significantly associated risk factors were largely similar to those for earlier readmission.

CONCLUSION

Women with comorbidities, with birth-related complications, of non-Hispanic black race and ethnicity, or with less education had increased odds of postpartum readmission after having a stillbirth, highlighting the importance of continued care for these women after discharge from the hospital.

Association between delivering live-born twins and acute psychiatric illness within 1 year of delivery

BACKGROUND

Having twins is associated with more depressive symptoms than having singletons. However, the association between having twins and psychiatric morbidity requiring emergency department visit or inpatient hospitalization is less well known.

OBJECTIVE

This study aimed to determine whether women have higher risk of having a psychiatric diagnosis at an emergency department visit or inpatient admission in the year after having twins vs singletons.

STUDY DESIGN

This retrospective cohort study used International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis and procedure codes within the Florida State Inpatient Database and State Emergency Department Database, which have an encrypted identifier allowing nearly all inpatient and emergency department encounters statewide to be linked to the medical record. The first delivery of Florida residents at the age of 13 to 55 years from 2005 to 2014 was included, regardless of parity; women with International Classification of Diseases, Ninth Revision, Clinical Modification coding for psychiatric illness or substance misuse during pregnancy or for stillbirth or higher-order gestations were excluded. The exposure was an International Classification of Diseases, Ninth Revision, Clinical Modification code during delivery hospitalization of live-born twins. The primary outcome was an International Classification of Diseases, Ninth Revision, Clinical Modification code during an emergency department encounter or inpatient admission within 1 year of delivery for a psychiatric morbidity composite (suicide attempt, depression, anxiety, posttraumatic stress disorder, psychosis, acute stress reaction, or adjustment disorder). The secondary outcome was drug or alcohol use or dependence within 1 year of delivery. We compared outcomes after delivery of live-born twins with singletons using multivariable logistic regression adjusting for sociodemographic and medical factors. We tested for interactions between independent variables in the primary model and conducted sensitivity analyses stratifying women by insurance type and presence of severe intrapartum morbidity or medical comorbidities.

RESULTS

A total of 17,365 women who had live-born twins and 1,058,880 who had singletons were included. Within 1 year of birth, 1.6% of women delivering twins (n=270) and 1.6% of women delivering singletons (n=17,236) had an emergency department encounter or inpatient admission coded for psychiatric morbidity (adjusted odds ratio, 1.00; 95% confidence interval, 0.88-1.14). Coding for drug or alcohol use or dependence in an emergency department encounter or inpatient admission in the year after twin vs singleton delivery was also similar (n=96 [0.6%] vs n=6222 [0.6%]; adjusted odds ratio, 1.11; 95% confidence interval, 0.91-1.36). However, women with public health insurance were more likely to be coded for drug or alcohol use or dependence after twin than singleton delivery (n=75 [1.2%] vs n=4858 [1.0%]; adjusted odds ratio, 1.27; 95% confidence interval, 1.01-1.60). Women with ≥1 medical comorbidity, severe maternal morbidity, or low income also had an increased risk of psychiatric morbidity after twin delivery (comorbidities, n=7438 [42.8%]; adjusted odds ratio, 1.30; 95% confidence interval, 1.25-1.34; severe maternal morbidity, n=940 [5.4%]; adjusted odds ratio, 1.65; 95% confidence interval, 1.49-1.81; lowest income quartile, n=4409 [26.8%]; adjusted odds ratio, 1.31; 95% confidence interval, 1.23-1.40; second-lowest income quartile, n=4770 [29.0%]; adjusted odds ratio, 1.34; 95% confidence interval, 1.26-1.43).

CONCLUSION

Overall, diagnostic codes for psychiatric illness or substance misuse in emergency department visits or hospital admissions in the year after twin vs singleton delivery are similar. However, women with who are low income or have public health insurance, comorbidities, or severe maternal morbidity are at an increased risk of postpartum psychiatric morbidity after twin vs singleton delivery.

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.

Association Between Stillbirth at 23 Weeks of Gestation or Greater and Severe Maternal Morbidity

OBJECTIVE

To estimate whether stillbirth at 23 weeks of gestation or more is associated with increased risk of severe maternal morbidity compared with live birth, when stratified by maternal comorbidities.

METHODS

This retrospective cohort study used International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis and procedure codes within the Healthcare Cost and Utilization Project's Florida State Inpatient Database. The first delivery of female Florida residents aged 13-54 years old from 2005 to 2014 was included. The exposure was an ICD-9-CM code of stillbirth at 23 weeks of gestation or more; the control was an ICD-9-CM code of singleton live birth. Deliveries were stratified by the presence of 1 or more conditions within a well-validated maternal morbidity composite using ICD-9-CM codes during delivery hospitalization. The primary outcome was an ICD-9-CM diagnosis or procedure code during delivery hospitalization of any indices within the Centers for Disease Control and Prevention's severe maternal morbidity composite. Multivariable analyses adjusted for maternal sociodemographic factors and delivery mode to compare outcomes after stillbirth with live-birth delivery.

RESULTS

Nine thousand five hundred twenty-three women who delivered stillborn fetuses and 1,353,044 with liveborn neonates were included. Among 6,590 stillbirths and 935,913 live births without maternal comorbidities, severe maternal morbidity was significantly more common during stillbirth delivery (n=345 [5.2%]), corresponding to a seven-fold increased risk compared with live birth (n=8,318 [0.9]; adjusted odds ratio [aOR] 7.05 [95% CI 6.27-7.93]). Among 2,933 stillbirths and 417,131 live births with maternal comorbidities, severe maternal morbidity was significantly more common during stillbirth delivery (n=390 [13.3%]): the risk was more than six-fold higher comparatively (n=11,122 [2.7%]; aOR 6.21 [95% CI 5.54-6.96]). Most maternal comorbidities were individually associated with higher risk of severe maternal morbidity during stillbirth compared with live-birth delivery.

CONCLUSION

Though severe maternal morbidity is overall uncommon, delivering a stillborn fetus 23 weeks of gestation or greater is associated with increased likelihood of severe maternal morbidity, particularly among women with comorbidities, suggesting health care providers must be vigilant about severe maternal morbidity during stillbirth delivery.

Association Between Severe Maternal Morbidity and Psychiatric Illness Within 1 Year of Hospital Discharge After Delivery

OBJECTIVE

To estimate whether severe maternal morbidity is associated with increased risk of psychiatric illness in the year after delivery hospital discharge.

METHODS

This retrospective cohort study used International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes within Florida's Healthcare Cost and Utilization Project's databases. The first liveborn singleton delivery from 2005 to 2015 was included; women with ICD-9-CM codes for psychiatric illness or substance use disorder during pregnancy were excluded. The exposure was ICD-9-CM codes during delivery hospitalization of severe maternal morbidity, as per the Centers for Disease Control and Prevention. The primary outcome was ICD-9-CM codes in emergency department encounter or inpatient admission within 1 year of hospital discharge of composite psychiatric morbidity (suicide attempt, depression, anxiety, posttraumatic stress disorder, psychosis, acute stress reaction, or adjustment disorder). The secondary outcome was a composite of ICD-9-CM codes for substance use disorder. We compared women with severe maternal morbidity with those without severe maternal morbidity using multivariable logistic regression adjusting for sociodemographic factors and medical comorbidities. Cox proportional hazard models identified the highest risk period after hospital discharge for the primary outcome.

RESULTS

A total of 15,510 women with severe maternal morbidity and 1,178,458 without severe maternal morbidity were included. Within 1 year of hospital discharge, 2.9% (n=452) of women with severe maternal morbidity had the primary outcome compared with 1.6% (n=19,279) of women without severe maternal morbidity, resulting in an adjusted odds ratio (aOR) 1.74 (95% CI 1.58-1.91). The highest risk interval was within 4 months of discharge (adjusted hazard ratio [adjusted HR] 2.53 [95% CI 2.05-3.12]). Most severe maternal morbidity conditions were associated with higher risk of postpartum psychiatric illness. Women with severe maternal morbidity had nearly twofold higher risk of postpartum substance use disorder (170 [1.1%] vs 6,861 [0.6%]; aOR 1.91 [95% CI 1.64-2.23]).

CONCLUSION

Though absolute numbers were modest, severe maternal morbidity was associated with increased risk of severe postpartum psychiatric morbidity and substance use disorder. The highest period of risk extended to 4 months after hospital discharge.
