When should women be screened for postnatal depression?

Cost-effectiveness of screening tools for identifying depression in early pregnancy: a decision tree model

Background

Although the effectiveness of screening tools for detecting depression in pregnancy has been investigated, there is limited evidence on the cost-effectiveness. This is vital in providing full information to decision makers. This study aimed to explore the cost-effectiveness of different screening tools to identify depression in early pregnancy compared to no screening.

Methods

A decision tree was developed to model the identification and treatment pathways of depression from the first antenatal appointment to 3-months postpartum using the Whooley questions, the Edinburgh Postnatal Depression Scale (EPDS) and the Whooley questions followed by the EPDS, compared to no screening. The economic evaluation took an NHS and Personal Social Services perspective. Model parameters were taken from a combination of sources including a cross-sectional survey investigating the diagnostic accuracy of screening tools, and other published literature. Cost-effectiveness was assessed in terms of the incremental cost per quality adjusted life years (QALYs). Cost-effectiveness planes and cost-effectiveness acceptability curves were produced using a net-benefit approach based on Monte Carlo simulations of cost-outcome data.

Results

In a 4-way comparison, the Whooley, EPDS and Whooley followed by the EPDS each had a similar probability of being cost-effective at around 30% for willingness to pay values from £20,000–30,000 per QALY compared to around 20% for the no screen option.

Conclusions

All three screening approaches tested had a higher probability of being cost-effective than the no-screen option. In the absence of a clear cost-effectiveness advantage for any one of the three screening options, the choice between the screening approaches could be made on other grounds, such as clinical burden of the screening options. Limitations include data availability and short time horizon, thus further research is needed.

Patterns of peripartum depression screening and detection in a large, multi-site, integrated healthcare system

The purpose of this study was to examine peripartum depression (PD) screening patterns within and across the prenatal and postpartum periods and assess the incidence of new positive screens during standard screening protocol timepoints to inform practice, particularly when limited screenings can be conducted.This is a retrospective observational study of women screened for PD through a large, integrated health system using the Edinburgh Postnatal Depression Scale (EPDS) within their obstetrics and pediatric practices. Pregnancies with an EPDS score for at least one obstetric and one pediatric appointment between November 2016 and October 2019 were included (n = 3240). The data were analyzed using chi-squared test, Student's t-test, and binary logistic regression analyses. An EPDS score of 10 or higher was considered a positive screen.The positive screening rate for this cohort was 18.5%, with a prenatal positive rate of 9.9% and a postpartum positive rate of 8.6%. Single relationship status showed a higher rate of PD overall. Two thirds of women were not screened until their third trimester, resulting in delayed detection for an estimated 28% of women who ultimately screened positive. Few new positive screens (1.3%) were detected after 9 weeks postpartum in women who had completed all recommended prior screens.Obstetric providers should screen for PD as early in pregnancy as possible and continue to screen as often as feasible regardless of previous negative EPDS scores. Prioritizing screening more often in pregnancy and before 9 weeks postpartum is optimal to avoid delays in detection and intervention.

An exploratory parallel-group randomised controlled trial of antenatal Guided Self-Help (plus usual care) versus usual care alone for pregnant women with depression: DAWN trial

BACKGROUND

Depression is a common antenatal mental disorder associated with significant maternal morbidity and adverse fetal outcomes. However, there is a lack of research on the effectiveness or cost-effectiveness of psychological interventions for antenatal depression.

METHODS

A parallel-group, exploratory randomised controlled trial across five hospitals. The trial compared Guided Self-Help, modified for pregnancy, plus usual care with usual care alone for pregnant women meeting DSM-IV criteria for mild-moderate depression. The trial objectives were to establish recruitment/follow-up rates, compliance and acceptability, and to provide preliminary evidence of intervention efficacy and cost-effectiveness. The primary outcome of depressive symptoms was assessed by blinded researchers using the Edinburgh Postnatal Depression Scale at 14-weeks post-randomisation.

RESULTS

620 women were screened, 114 women were eligible and 53 (46.5%) were randomised. 26 women received Guided Self-Help - 18 (69%) attending ≥4 sessions - and 27 usual care; n = 3 women were lost to follow-up (follow-up rate for primary outcome 92%). Women receiving Guided Self-Help reported fewer depressive symptoms at follow-up than women receiving usual care (adjusted effect size -0.64 (95%CI: -1.30, 0.06) p = 0.07). There were no trial-related adverse events. The cost-effectiveness acceptability curve showed the probability of Guided Self-Help being cost-effective compared with usual care ranged from 10 to 50% with a willingness-to-pay range from £0 to £50,000.

CONCLUSIONS AND LIMITATIONS

Despite intense efforts we did not meet our anticipated recruitment target. However, high levels of acceptability, a lack of adverse events and a trend towards improvements in symptoms of depression post-treatment indicates this intervention is suitable for talking therapy services.

Depression: an exploratory parallel-group randomised controlled trial of Antenatal guided self help for WomeN (DAWN): study protocol for a randomised controlled trial

BACKGROUND

Depression is a common antenatal mental disorder and is associated with an increased risk of adverse effects on the fetus and significant morbidity for the mother; if untreated it can also continue into the post-natal period and affect mother-infant interactions. There has been little research evaluating the effectiveness or cost-effectiveness of antenatal psychological interventions for antenatal depression, particularly for mild to moderate disorders. International guidelines recommend a stepped care approach starting with Guided Self Help, and the aim of this exploratory trial is to investigate Guided Self Help modified for pregnancy.

METHODS

The DAWN trial is an exploratory randomised controlled trial of the effectiveness and cost-effectiveness of antenatal Guided Self Help, modified for pregnancy and delivered by National Health Service Psychological Wellbeing Practitioners. Antenatal Guided Self Help, in addition to usual care, is compared with usual care for pregnant women diagnosed with mild to moderate depression and mixed anxiety and depression, using the Structured Clinical Interview for DSM-IV Disorders. Modifications for pregnancy include perinatal mental health training, addressing pregnancy-specific worries and including sections on health issues in pregnancy and planning for parenthood. Women allocated to Guided Self Help will be seen for up to eight sessions by a Psychological Wellbeing Practitioner (including an initial assessment session); there will also be an appointment at 12 weeks after delivery. Research measures including the Edinburgh Postnatal Depression Scale (primary outcome) and other measures of depression, anxiety, quality of life and service use will be collected from women before random allocation, 14 weeks after random allocation and at 12 weeks after delivery. Potential psychological mechanisms of the intervention will be explored using the Pregnancy-Related Thoughts Questionnaire and the Metacognitive Awareness Questionnaire.

DISCUSSION

The DAWN trial is the first exploratory trial to investigate the efficacy of antenatal Guided Self Help for pregnant women with mild to moderate depression meeting DSM-IV diagnostic criteria. Recruitment started January 2015 and is expected to be completed by July 2016.

Effectiveness of Structured Education in Reduction of Postpartum Depression Scores: A Quasi-Experimental Study

The aim of this study was to evaluate effectiveness of structured education in reduction of postpartum depression scores among women. This was a quasi-experimental study with a pre-post tests and a control group. Non-random sampling was used and the study included a total of 103 Turkish women, 52 of whom were in the intervention group and 51 were in the control group. The women in the intervention group were offered structured education for postpartum depression and given structured education material. Effectiveness of the education given was evaluated by comparing scores for Edinburg Postpartum Depression Scale obtained before and after delivery between the intervention and the control groups. Before education, median score (8.0±4.8) for Edinburg Postpartum Depression Scale of the intervention group were significantly higher the than the control group (6.0±6.0, p=0.010), but the groups were statistically similar in terms of having depression (intervention: 17.3%, control: 11.8%, p=0.425). After education, the median score for Edinburg Postpartum Depression Scale and the ratio of the women having depression in the intervention group were significantly lower than in the control group (respectively intervention: 4.0±3.0, control: 10.0±4.0, p=0.000; intervention: 7.7%, control: 25.5%, p=0.015). Besides, the median score (8.0±4.8) of the intervention group before education were significantly higher than the score (4.0±3.0) obtained after education (p=0.000), while the median score (6.0±6.0) of the control group before education were lower than the score (10.0±4.0) obtained after education (p=0.000). This study revealed that structured education offered to women by nurses was effective in reducing the postpartum depression scores and the numbers of women having depression.

Bad thoughts: Brazilian women's responses to mothering while experiencing postnatal depression

OBJECTIVE

this study explores Brazilian women's experiences of mothering of their infants while experiencing postnatal depression.

DESIGN

a cross-language qualitative descriptive design.

METHOD

the sample was composed of 15 women diagnosed with postnatal depression in a psychiatric institute in São Paulo, Brazil. Open-ended interviews were conducted and the data underwent thematic analysis.

RESULTS

13 women worried that harm would come to their infants. Seven of these women self-identified as potential sources of harm, with two women physically hurting their infants. The remaining six women worried about unknown agents, such as disease, hurting their infants. In response to these bad thoughts, women mothered their infants in one of four ways: (1) transferred care, completely delegating this task to family members; (2) shared care, asking family members to share the responsibility; (3) sole care, having to look after their infants by themselves because they had no available family support; (4) and smother care, being hyper-vigilant, constantly watching their infants and not trusting infant care to anyone else.

CONCLUSIONS

the bad thoughts influenced the women's adaptation to mothering their infants. Health professionals should assess these thoughts early in the postnatal period and the women's mothering responses for the protection of mother and child.

Domestic violence and perinatal mental disorders: a systematic review and meta-analysis

BACKGROUND

Domestic violence in the perinatal period is associated with adverse obstetric outcomes, but evidence is limited on its association with perinatal mental disorders. We aimed to estimate the prevalence and odds of having experienced domestic violence among women with antenatal and postnatal mental disorders (depression and anxiety disorders including post-traumatic stress disorder [PTSD], eating disorders, and psychoses).

METHODS AND FINDINGS

We conducted a systematic review and meta-analysis (PROSPERO reference CRD42012002048). Data sources included searches of electronic databases (to 15 February 2013), hand searches, citation tracking, update of a review on victimisation and mental disorder, and expert recommendations. Included studies were peer-reviewed experimental or observational studies that reported on women aged 16 y or older, that assessed the prevalence and/or odds of having experienced domestic violence, and that assessed symptoms of perinatal mental disorder using a validated instrument. Two reviewers screened 1,125 full-text papers, extracted data, and independently appraised study quality. Odds ratios were pooled using meta-analysis. Sixty-seven papers were included. Pooled estimates from longitudinal studies suggest a 3-fold increase in the odds of high levels of depressive symptoms in the postnatal period after having experienced partner violence during pregnancy (odds ratio 3.1, 95% CI 2.7-3.6). Increased odds of having experienced domestic violence among women with high levels of depressive, anxiety, and PTSD symptoms in the antenatal and postnatal periods were consistently reported in cross-sectional studies. No studies were identified on eating disorders or puerperal psychosis. Analyses were limited because of study heterogeneity and lack of data on baseline symptoms, preventing clear findings on causal directionality.

CONCLUSIONS

High levels of symptoms of perinatal depression, anxiety, and PTSD are significantly associated with having experienced domestic violence. High-quality evidence is now needed on how maternity and mental health services should address domestic violence and improve health outcomes for women and their infants in the perinatal period.

Revising acute care systems and processes to improve breastfeeding and maternal postnatal health: a pre and post intervention study in one English maternity unit

BACKGROUND

Most women in the UK give birth in a hospital labour ward, following which they are transferred to a postnatal ward and discharged home within 24 to 48 hours of the birth. Despite policy and guideline recommendations to support planned, effective postnatal care, national surveys of women's views of maternity care have consistently found in-patient postnatal care, including support for breastfeeding, is poorly rated.

METHODS

Using a Continuous Quality Improvement approach, routine antenatal, intrapartum and postnatal care systems and processes were revised to support implementation of evidence based postnatal practice. To identify if implementation of a multi-faceted QI intervention impacted on outcomes, data on breastfeeding initiation and duration, maternal health and women's views of care, were collected in a pre and post intervention longitudinal survey. Primary outcomes included initiation, overall duration and duration of exclusive breastfeeding. Secondary outcomes included maternal morbidity, experiences and satisfaction with care. As most outcomes of interest were measured on a nominal scale, these were compared pre and post intervention using logistic regression.

RESULTS

Data were obtained on 741/1160 (64%) women at 10 days post-birth and 616 (54%) at 3 months post-birth pre-intervention, and 725/1153 (63%) and 575 (50%) respectively post-intervention. Post intervention there were statistically significant differences in the initiation (p = 0.050), duration of any breastfeeding (p = 0.020) and duration of exclusive breastfeeding to 10 days (p = 0.038) and duration of any breastfeeding to three months (p = 0.016). Post intervention, women were less likely to report physical morbidity within the first 10 days of birth, and were more positive about their in-patient care.

CONCLUSIONS

It is possible to improve outcomes of routine in-patient care within current resources through continuous quality improvement.

The prevalence of suicidal ideation identified by the Edinburgh Postnatal Depression Scale in postpartum women in primary care: findings from the RESPOND trial

1 Abstract

Childbirth and mental disorders

This review approaches the topic of childbirth and mental illness using a model of perinatal health which takes into consideration the multiple determinants of health, approached from a lifespan perspective. The paper seeks to answer four broad questions using this model and available literature: (1) What is the relationship between childbirth and mental disorders? (2) How common are mental disorders during childbearing, and what is the perinatal course of illness? (3) What are the effects of mental illness during childbearing on foetal and infant developmental outcomes? (4) How do you approach the detection and treatment of mental disorders during the perinatal period?
