Is it clinically and cost effective to screen for postnatal depression: a systematic review of controlled clinical trials and economic evidence

Meta-Analyses of Genome-Wide Association Studies for Postpartum Depression

OBJECTIVE

Postpartum depression (PPD) is a common subtype of major depressive disorder (MDD) that is more heritable, yet is understudied in psychiatric genetics. The authors conducted meta-analyses of genome-wide association studies (GWASs) to investigate the genetic architecture of PPD.

METHOD

Meta-analyses were conducted on 18 cohorts of European ancestry (17,339 PPD cases and 53,426 controls), one cohort of East Asian ancestry (975 cases and 3,780 controls), and one cohort of African ancestry (456 cases and 1,255 controls), totaling 18,770 PPD cases and 58,461 controls. Post-GWAS analyses included 1) single-nucleotide polymorphism (SNP)-based heritability ([Formula: see text]), 2) genetic correlations between PPD and other phenotypes, and 3) enrichment of the PPD GWAS findings in 27 human tissues and 265 cell types from the mouse central and peripheral nervous system.

RESULTS

No SNP achieved genome-wide significance in the European or the trans-ancestry meta-analyses. The [Formula: see text] of PPD was 0.14 (SE=0.02). Significant genetic correlations were estimated for PPD with MDD, bipolar disorder, anxiety disorders, posttraumatic stress disorder, insomnia, age at menarche, and polycystic ovary syndrome. Cell-type enrichment analyses implicate inhibitory neurons in the thalamus and cholinergic neurons within septal nuclei of the hypothalamus, a pattern that differs from MDD.

CONCLUSIONS

While more samples are needed to reach genome-wide levels of significance, the results presented confirm PPD as a polygenic and heritable phenotype. There is also evidence that despite a high correlation with MDD, PPD may have unique genetic components. Cell enrichment results suggest GABAergic neurons, which converge on a common mechanism with the only medication approved by the U.S. Food and Drug Administration for PPD (brexanolone).

The longitudinal effects of stress and fear on psychiatric symptoms in mothers during the COVID-19 pandemic

The COVID-19 pandemic has been particularly difficult for mothers. Women with a history of peripartum depression (PPD) may be vulnerable to relapse. We sought to understand changes in depressive and anxious symptoms throughout the pandemic and which stressors increased symptoms in women with a history of PPD. In June 2020, all US participants with a history of PPD (n = 12,007) in the global MomGenes Fight PPD study were invited to the COVID-19 follow-up study. Respondents (n = 2163, 18%) were sent biweekly and then monthly surveys until January 31, 2022. We employed time-varying effects models to evaluate trajectories of depressive (patient health questionnaire, PHQ-9) and anxious (generalized anxiety disorder, GAD-7) symptoms and to estimate longitudinal associations between perceived stress, fears, COVID-19 case rates, and symptoms. Peaks of PHQ-9, GAD-7, PSS, and perceived COVID-19 risk scores corresponded with timing of national COVID-19 case surges. High perceived stress was the strongest predictor of PHQ-9 (beta = 7.27; P = 1.48e - 38) and GAD-7 (beta = 7.73; P = 6.19e - 70). Feeling lack of control and unlikely to survive increased PHQ-9 and GAD-7 scores by 2 points. COVID-19 case rates, pandemic restrictions, and region were not independently associated with symptoms. This study suggests that the collective trauma of the pandemic has significantly affected mothers with a history of PPD, exemplified by high levels of perceived stress and the strong association with depressive and anxious symptoms. The next pandemic phase is uncertain, but will continue to influence mental health collectively and dynamically. Interventions must be flexible and responsive and should address fear, trauma, and feelings of control, particularly for mothers with a history of PPD.

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.

App-Based Ecological Momentary Assessment to Enhance Clinical Care for Postpartum Depression: Pilot Acceptability Study

Background

Wearable tracking devices and mobile health technology are increasingly used in an effort to enhance clinical care and the delivery of personalized medical treatment. Postpartum depression is the most frequently diagnosed complication of childbirth; however, significant gaps in screening and treatment remain.

Objective

This study aims to investigate the clinical utility, predictive ability, and acceptability of using ecological momentary assessment to collect daily mood, sleep, and activity data through the use of an Apple Watch and mobile app among women with postpartum depression.

Methods

This was a pilot study consisting of 3 in-person research visits over the course of a 6-week enrollment period. Questionnaires to assess depression, anxiety, and maternal functioning were periodically collected, along with daily self-reported symptoms and passively collected physiological data via an Apple Watch. Feedback was collected from study participants and the study clinician to determine the utility and acceptability of daily tracking. Logistic regression was used to determine whether mood scores in the 2 weeks before a visit predicted scores at follow-up. Compliance with daily assessments was also measured.

Results

Of the 26 women enrolled, 23 (88%) completed the 6-week study period. On average, the participants completed 67% (34.4/51.5 days) of all active daily assessments and 74% (38/51.5 days) of all passive measures. Furthermore, all 23 participants completed the 3 required visits with the research team. Predictive correlations were found between self-reported mood and Edinburgh Postnatal Depression Scale score at follow-up, self-reported anxiety and EDPS, and sleep quality and Edinburgh Postnatal Depression Scale.

Conclusions

Using ecological momentary assessment to track daily symptoms of postpartum depression using a wearable device was largely endorsed as acceptable and clinically useful by participants and the study clinician and could be an innovative solution to increase care access during the COVID-19 pandemic.

mHealth Solutions for Perinatal Mental Health: Scoping Review and Appraisal Following the mHealth Index and Navigation Database Framework

Background

The ever-increasing pressure on health care systems has resulted in the underrecognition of perinatal mental disorders. Digital mental health tools such as apps could provide an option for accessible perinatal mental health screening and assessment. However, there is a lack of information regarding the availability and features of perinatal app options.

Objective

This study aims to evaluate the current state of diagnostic and screening apps for perinatal mental health available on the Google Play Store (Android) and Apple App Store (iOS) and to review their features following the mHealth Index and Navigation Database framework.

Methods

Following a scoping review approach, the Apple App Store and Google Play Store were systematically searched to identify perinatal mental health assessment apps. A total of 14 apps that met the inclusion criteria were downloaded and reviewed in a standardized manner using the mHealth Index and Navigation Database framework. The framework comprised 107 questions, allowing for a comprehensive assessment of app origin, functionality, engagement features, security, and clinical use.

Results

Most apps were developed by for-profit companies (n=10), followed by private individuals (n=2) and trusted health care companies (n=2). Out of the 14 apps, 3 were available only on Android devices, 4 were available only on iOS devices, and 7 were available on both platforms. Approximately one-third of the apps (n=5) had been updated within the last 180 days. A total of 12 apps offered the Edinburgh Postnatal Depression Scale in its original version or in rephrased versions. Engagement, input, and output features included reminder notifications, connections to therapists, and free writing features. A total of 6 apps offered psychoeducational information and references. Privacy policies were available for 11 of the 14 apps, with a median Flesch-Kincaid reading grade level of 12.3. One app claimed to be compliant with the Health Insurance Portability and Accountability Act standards and 2 apps claimed to be compliant with General Data Protection Regulation. Of the apps that could be accessed in full (n=10), all appeared to fulfill the claims stated in their description. Only 1 app referenced a relevant peer-reviewed study. All the apps provided a warning for use, highlighting that the mental health assessment result should not be interpreted as a diagnosis or as a substitute for medical care. Only 3 apps allowed users to export or email their mental health test results.

Conclusions

These results indicate that there are opportunities to improve perinatal mental health assessment apps. To this end, we recommend focusing on the development and validation of more comprehensive assessment tools, ensuring data protection and safety features are adequate for the intended app use, and improving data sharing features between users and health care professionals for timely support.

Proof-of-Concept Support for the Development and Implementation of a Digital Assessment for Perinatal Mental Health: Mixed Methods Study

Background

Perinatal mental health symptoms commonly remain underdiagnosed and undertreated in maternity care settings in the United Kingdom, with outbreaks of disease, like the COVID-19 pandemic, further disrupting access to adequate mental health support. Digital technologies may offer an innovative way to support the mental health needs of women and their families throughout the perinatal period, as well as assist midwives in the recognition of perinatal mental health concerns. However, little is known about the acceptability and perceived benefits and barriers to using such technologies.

Objective

The aim of this study was to conduct a mixed methods evaluation of the current state of perinatal mental health care provision in the United Kingdom, as well as users’ (women and partners) and midwives’ interest in using a digital mental health assessment throughout the perinatal period.

Methods

Women, partners, and midwives were recruited to participate in the study, which entailed completing an online survey. Quantitative data were explored using descriptive statistics. Open-ended response data were first investigated using thematic analysis. Resultant themes were then mapped onto the components of the Capability, Opportunity, and Motivation Behavior model and summarized using descriptive statistics.

Results

A total of 829 women, 103 partners, and 90 midwives participated in the study. The provision of adequate perinatal mental health care support was limited, with experiences varying significantly across respondents. There was a strong interest in using a digital mental health assessment to screen, diagnose, and triage perinatal mental health concerns, particularly among women and midwives. The majority of respondents (n=781, 76.42%) expressed that they would feel comfortable or very comfortable using or recommending a digital mental health assessment. The majority of women and partners showed a preference for in-person consultations (n=417, 44.74%), followed by a blended care approach (ie, both in-person and online consultations) (n=362, 38.84%), with fewer participants preferring online-only consultations (n=120, 12.88%). Identified benefits and barriers mainly related to physical opportunity (eg, accessibility), psychological capability (eg, cognitive skills), and automatic motivation (eg, emotions).

Conclusions

This study provides proof-of-concept support for the development and implementation of a digital mental health assessment to inform clinical decision making in the assessment of perinatal mental health concerns in the United Kingdom.

Maternal depression symptoms during the first 21 months after giving birth

Aims:

The first year after childbirth involves a major transition for women, which can accentuate inadequacies and feelings of powerlessness, making them vulnerable to depression. The aim of this study was to investigate the prevalence and frequency of maternal postpartum depressive symptoms at different times after giving birth (0–21 months).

Methods:

Data were collected cross-sectionally using a web questionnaire containing the Edinburgh Postnatal Depression Scale (EPDS). A total of 888 mothers with children in the age range 0–21 months responded.

Results:

The results showed different levels of depression over the range of months included in the study. The overall prevalence using EPDS ⩾ 12 was 27.8%. There were higher levels at 9–12 months and 17–21 months. The highest levels of symptoms of depression were found at nine, 12, and 17 months after birth, and the lowest levels at two and 16 months.

Conclusions:

Many mothers experience symptoms of depression after giving birth that can continue well beyond the child’s first year. We have identified different levels of depression at different points in time after giving birth, with highs and lows throughout the first 21 months. This highlights a need to screen for depression more than once during the first years, as well as a closer cooperation between midwives and child healthcare nurses in supporting mothers in the transition to motherhood. This is an important aspect of public health, which not only involves mothers with symptoms of depression, but also their ability to care for their child and a possible negative impact on the child’s development.

Uptake of referrals for women with positive perinatal depression screening results and the effectiveness of interventions to increase uptake: a systematic review and meta-analysis

AIMS

Perinatal depression threatens the health of maternal women and their offspring. Although screening programs for perinatal depression exist, non-uptake of referral to further mental health care after screening reduces the utility of these programs. Uptake rates among women with positive screening varied widely across studies and little is known about how to improve the uptake rate. This study aimed to systematically review the available evidence on uptake rates, estimate the pooled rate, identify interventions to improve uptake of referral and explore the effectiveness of those interventions.

METHODS

This systematic review has been registered in PROSPERO (registration number: CRD42019138095). We searched Pubmed, Web of Science, Cochrane Library, Ovid, Embase, CNKI, Wanfang Database and VIP Databases from database inception to January 13, 2019 and scanned reference lists of relevant researches for studies published in English or Chinese. Studies providing information on uptake rate and/or effectiveness of interventions on uptake of referral were eligible for inclusion. Studies were excluded if they did not report the details of the referral process or did not provide exact uptake rate. Data provided by observational studies and quasi-experimental studies were used to estimate the pooled uptake rate through meta-analysis. We also performed meta-regression and subgroup analyses to explore the potential source of heterogeneity. To evaluate the effectiveness of interventions, we conducted descriptive analyses instead of meta-analyses since there was only one randomised controlled trial (RCT).

RESULTS

Of 2302 records identified, 41 studies were eligible for inclusion, including 39 observational studies (n = 9337), one quasi-experimental study (n = 43) and one RCT (n = 555). All but two studies were conducted in high-income countries. The uptake rates reported by included studies varied widely and the pooled uptake rate of referral was 43% (95% confidence intervals [CI] 35-50%) by a random-effect model. Meta-regression and subgroup analyses both showed that referral to on-site assessment or treatment (60%, 95% CI 51-69%) had a significantly higher uptake rate than referral to mental health service (32%, 95% CI 23-41%) (odds ratio 1.31, 95% CI 1.13-1.52). The included RCT showed that the referral intervention significantly improved the uptake rate (p ＜ 0.01).

CONCLUSIONS

Almost three-fifths of women with positive screening results do not take up the referral offers after perinatal depression screening. Referral to on-site assessment and treatment may improve uptake of referral, but the quality of evidence on interventions to increase uptake was weak. More robust studies are needed, especially in low-and middle-income countries.

Understanding barriers to women seeking and receiving help for perinatal mental health problems in UK general practice: development of a questionnaire

Aim:

To develop a questionnaire to measure quantitatively barriers and facilitators to women’s disclosure of perinatal mental health problems in UK primary care. To pilot and evaluate the questionnaire for content validity and internal consistency.

Background:

Around 15% of women develop a mental illness in the perinatal period, such as depression, anxiety or post-traumatic stress disorder. In the United Kingdom, 90% of these women will be cared for in primary care, yet currently in as many as 50% of cases, no discussion of this issue takes place. One reason for this is that women experience barriers to disclosing symptoms of perinatal mental illness in primary care. These have previously been explored qualitatively, but no tool currently exists with which to measure these barriers quantitatively.

Methods:

Questionnaire items, drawn from qualitative literature and accounts of women’s experiences, were identified, refined iteratively and arranged in themes. The questionnaire was piloted using cognitive debriefing interviews to establish content validity. Women completed a refined version online. Responses were analysed using descriptive statistics. Internal consistency of subscales was calculated using Cronbach’s alpha.

Findings:

Cognitive debriefing interviews with five women showed the majority of questionnaire items were relevant, appropriate and easy to understand. The final questionnaire was completed by 71 women, and the majority of subscales had good internal consistency. The barrier scoring most highly was fear and stigma, followed by willingness to seek help and logistics of attending an appointment. Family/partner support and general practitioners’ (GPs) reaction were the lowest scoring barriers. Factors facilitating disclosure were GPs being empathetic and non-judgemental and listening during discussions. In the future, this questionnaire can be used to examine which barriers are most important for particular groups of women. This may enable the development of strategies to improve acknowledgement and discussion, and prevent under-recognition and under-treatment, of perinatal mental health problems in primary care.

Cost-effectiveness of PoNDER health visitor training for mothers at lower risk of depression: findings on prevention of postnatal depression from a cluster-randomised controlled trial

BACKGROUND

There is evidence for the cost-effectiveness of health visitor (HV) training to assess postnatal depression (PND) and deliver psychological approaches to women at risk of depression. Whether this approach is cost-effective for lower-risk women is unknown. There is a need to know the cost of HV-delivered universal provision, and how much it might cost to improve health-related quality of life for postnatal women. A sub-study of a cluster-randomised controlled trial in the former Trent region (England) previously investigated the effectiveness of PoNDER HV training in mothers at lower risk of PND. We conducted a parallel cost-effectiveness analysis at 6-months postnatal for all mothers with lower-risk status attributed to an Edinburgh Postnatal Depression Scale (EPDS) score <12 at 6-weeks postnatal.

METHODS

Intervention HVs were trained in assessment and cognitive behavioural or person-centred psychological support techniques to prevent depression. Outcomes examined: quality-adjusted life-year (QALY) gains over the period between 6 weeks and 6 months derived from SF-6D (from SF-36); risk-of-depression at 6 months (dichotomising 6-month EPDS scores into lower risk (<12) and at-risk (⩾12).

RESULTS

In lower-risk women, 1474 intervention (63 clusters) and 767 control participants (37 clusters) had valid 6-week and 6-month EPDS scores. Costs and outcomes data were available for 1459 participants. 6-month adjusted costs were £82 lower in intervention than control groups, with 0.002 additional QALY gained. The probability of cost-effectiveness at £20 000 was very high (99%).

CONCLUSIONS

PoNDER HV training was highly cost-effective in preventing symptoms of PND in a population of lower-risk women and cost-reducing over 6 months.

The international postpartum depression: action towards causes and treatment (PACT) consortium

The International Postpartum depression: Action towards Causes and Treatment (PACT) Consortium was founded with the overarching goal of creating an international perinatal psychiatry consortium to conduct novel investigations with large sample sizes to understand the genetic signature of perinatal mood disorders. PACT uses a collaborative and team science approach that includes investigators across 19 institutions and seven continents. The large sample sizes allow for statistically rigorous analyses to investigate perinatal psychiatric disorders, with an initial focus on postpartum depression (PPD). Our current aims are to identify clinical sub-types of PPD that contribute diagnostic heterogeneity, and to elucidate the genetic basis of PPD by conducting the first large genome-wide association study of PPD. To accomplish the latter aim, we are partnering with the Major Depressive Disorder Working Group of the Psychiatric Genomics Consortium. To date, our consortium members have recruited 17,912 participants and 11,344 participants have been identified using the PPD ACT mobile app, of which 8,432 are PPD cases. Ultimately, we hope this approach will improve detection, diagnosis, and treatment of women who suffer from perinatal psychiatric disorders.

PPD ACT: an app-based genetic study of postpartum depression

Postpartum depression (PPD) is one of the most frequent complications of childbirth and particularly is suited to genetic investigation as it is more homogenous than major depression outside of the perinatal period. We developed an iOS app (PPD ACT) to recruit, consent, screen, and enable DNA collection from women with a lifetime history of PPD to sufficiently power genome-wide association studies. In 1 year, we recruited 7344 women with a history of PPD and have biobanked 2946 DNA samples from the US. This sample of PPD cases was notably severely affected and within 2 years of their worst episode of PPD. Clinical validation was performed within a hospital setting on a subset of participants and recall validity assessed 6-9 months after initial assessment to ensure reliability of screening tools. Here we detail the creation of the PPD ACT mobile app including design, ethical, security, and deployment considerations. We emphasize the importance of multidisciplinary collaboration to correctly implement such a research project. Additionally, we describe our ability to customize the PPD ACT platform to deploy internationally in order to collect a global sample of women with PPD.

A pilot study evaluating depression in mothers with children diagnosed with Down syndrome in state health care

BACKGROUND

Parenting a child who has an intellectual disability has been shown to increase the risk for developing depression. The purpose of this study was to screen for depression and to determine if there is an association between depressive symptoms and certain sociodemographic factors in mothers with a child diagnosed with Down syndrome in state health care facilities in Johannesburg.

METHODS

The study included 30 biological mothers of children between 6 months and 3 years diagnosed with Down syndrome postnatally. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess depression in participants. A 10-item sociodemographic questionnaire was concurrently administered. Data analysis was conducted using descriptive and inferential statistical analysis.

RESULTS

The 30 mothers had a mean EPDS score of 9.1 (SD = 5.89) with scores ranging between 0 and 26. Eight mothers (26.7%) screened positive for depression with an EPDS score of 13 or greater. A statistically significant association was found between an HIV-positive status and mothers who had an EPDS score of 13 or greater (P = 0.01). No significant association between depression and various other sociodemographic factors was identified.

CONCLUSIONS

Mothers with a child diagnosed with Down syndrome may be vulnerable to developing depression. A significant association was found between a positive HIV status and symptoms of depression, in mothers with a child diagnosed with Down syndrome. This study indicates the need for further investigations assessing the causes and risk factors resulting in postnatal depression in mothers with a child diagnosed with Down syndrome.

Identifying perinatal depression with case-finding instruments: a mixed-methods study (BaBY PaNDA – Born and Bred in Yorkshire PeriNatal Depression Diagnostic Accuracy)

Background

Perinatal depression is well recognised as a mental health condition but < 50% of cases are identified in routine practice. A case-finding strategy using the Whooley questions is currently recommended by the National Institute for Health and Care Excellence.

Objectives

To determine the diagnostic accuracy, acceptability and cost-effectiveness of the Whooley questions and the Edinburgh Postnatal Depression Scale (EPDS) to identify perinatal depression.

Design

A prospective diagnostic accuracy cohort study, with concurrent qualitative and economic evaluations.

Setting

Maternity services in England.

Participants

A total of 391 pregnant women.

Main outcome measures

Women completed the Whooley questions, EPDS and a diagnostic reference standard (Clinical Interview Schedule – Revised) during pregnancy (20 weeks) and postnatally (3–4 months). Qualitative interviews were conducted with health professionals (HPs) and a subsample of women.

Results

Diagnostic accuracy results: depression prevalence rates were 10.3% during pregnancy and 10.5% postnatally. The Whooley questions and EPDS (cut-off point of ≥ 10) performed reasonably well, with comparable sensitivity [pregnancy: Whooley questions 85.0%, 95% confidence interval (CI) 70.2% to 94.3%; EPDS 82.5%, 95% CI 67.2% to 92.7%; postnatally: Whooley questions 85.7%, 95% CI 69.7% to 95.2%; EPDS 82.9%, 95% CI 66.4% to 93.4%] and specificity (pregnancy: Whooley questions 83.7%, 95% CI 79.4% to 87.4%; EPDS 86.6%, 95% CI 82.5% to 90.0%; postnatally: Whooley questions 80.6%, 95% CI 75.7% to 84.9%; EPDS 87.6%, 95% CI 83.3% to 91.1%). Diagnostic accuracy of the EPDS (cut-off point of ≥ 13) was poor at both time points (pregnancy: sensitivity 45%, 95% CI 29.3% to 61.5%, and specificity 95.7%, 95% CI 93.0% to 97.6%; postnatally: sensitivity 62.9%, 95% CI 44.9% to 78.5%, and specificity 95.7%, 95% CI 92.7% to 97.7%). Qualitative evaluation: women and HPs were supportive of screening/case-finding for perinatal depression. The EPDS was preferred to the Whooley questions by women and HPs, mainly because of its ‘softer’ wording. Whooley question 1 was thought to be less acceptable, largely because of the terms ‘depressed’ and ‘hopeless’, leading to women not revealing their depressive symptoms. HPs identified a ‘patient-centred’ environment that focused on the mother and baby to promote discussion about mental health. Cost-effectiveness results: screening/case-finding using the Whooley questions or the EPDS alone was not the most cost-effective strategy. A two-stage strategy, ‘Whooley questions followed by the Patient Health Questionnaire’ (a measure assessing depression symptomatology), was the most cost-effective strategy in the range between £20,000 and £30,000 per quality-adjusted life-year in both the prenatal and postnatal decision models.

Limitations

Perinatal depression diagnosis was not cross-referenced with women’s medical records so the proportion of new cases identified is unknown. The clinical effectiveness and cost-effectiveness of screening/case-finding strategies was not assessed as part of a randomised controlled trial.

Conclusions

The Whooley questions and EPDS had acceptable sensitivity and specificity, but their use in practice might be limited by low predictive value and variation in their acceptability. A two-stage strategy was more cost-effective than single-stage strategies. Neither case-finding instrument met National Screening Committee criteria.

Future work

The yield of screening/case-finding should be established with reference to health-care records. The clinical effectiveness and cost-effectiveness of screening/case-finding for perinatal depression needs to be tested in a randomised controlled trial.

Health professionals' perspective on the promotion of e-mental health apps in the context of maternal depression

OBJECTIVE

Our study focuses on exploring (1) the intention of health professionals to use and recommend e-mental health applications, (2) how this intention of health professionals might be influenced, (3) which group of health professionals might be most accessible to promote e-mental health applications for maternal depression, and (4) for which tasks they rate them to be most useful.

MATERIALS AND METHODS

Based on a questionnaire informed by the theory of planned behavior, we collected 131 responses of U.S., Spanish, and Swiss health professionals in the field of pregnancy and maternal care (including psychologists, psychiatrists, midwives, and doctors) by means of an online survey. We analyzed the gathered data applying a structured equation model.

RESULTS

Our study reveals that health professionals would in general intend to recommend and use e-mental health applications. However, their attitude towards e-mental health applications varies regarding the respective use cases and also differs among health professions.

CONCLUSION

We offer three alternative propositions for private or public organizations, associations, or any other entity whose purpose is service to the community for introducing e-mental health applications into practice.

Economic evaluation of interventions delivered by primary care providers to improve neurodevelopment in children aged under 5 years: protocol for a scoping review

BACKGROUND

Frequently cited benefit-cost ratios suggest that interventions to improve neurodevelopment have high economic returns when implemented during pregnancy and early childhood. However, there are many challenges when primary care providers implement these interventions at scale, and it is unclear how many research studies or programmes have examined cost-effectiveness and which methods were used. There are no current scoping or systematic reviews which have assessed economic evaluations of interventions delivered by primary care providers to improve child neurodevelopment.

METHODS/DESIGN

The aim of this review is to describe the economic evaluations of interventions delivered by primary care providers to improve neurodevelopment in children aged 0-4 years. Specific subgroup analyses will include income level of country (high, middle and low); population type (universal vs targeted); time period when intervention was implemented (antenatal vs infancy [0-11 months] vs early childhood [12-59 months]); and setting (research study vs programmes evaluation at scale). All study designs will be included. The primary outcomes of interest are cost per neurodevelopmental or cognitive health gain in children aged 0-4 years. All measures of cost, neurodevelopment or cognitive function that have been previously validated as an appropriate test in this domain will be included. Databases such as MEDLINE (OVID), PsycINFO (OVID), EMBASE (OVID), CINAHL, Cochrane Library (including CENTRAL, DARE, HTA and NHS EED), Paediatric Economic Database Evaluation (PEDE) and WHO databases and reference lists of papers will be searched for relevant articles. Five phases will be followed: identifying the research question, identifying relevant studies, study selection, charting data and collating, summarising and reporting results. We will present cost and effectiveness data descriptively.

DISCUSSION

This review appears to be the first to be conducted in this area. The findings will be an important resource for future systematic reviews on interventions that have a cost component. This information will be valuable for policy makers and programmers who work in public health or primary care settings.

Implementation of universal screening for depression during pregnancy: feasibility and impact on obstetric care

BACKGROUND

Given the growing policy and public health interest in the identification and treatment of depression in pregnancy, an understanding of the feasibility, challenges, and implications for resource utilization of the implementation of a universal screening program is crucial.

OBJECTIVE

The purpose of this study was to assess the feasibility of large-scale implementation of universal screening for depression in pregnancy and during the postpartum period with the use of the Edinburgh Postnatal Depression Scale.

STUDY DESIGN

A prospective observational cohort study was conducted from July 2010 to June 2014 at a large academic medical center. Pregnant women were screened at 24-28 weeks gestation and again 6 weeks postpartum. An Edinburgh Postnatal Depression Scale score of ≥12 was the cutoff for referral to mental health services for diagnostic evaluation and treatment.

RESULTS

Among 8985 women who were enrolled in prenatal care at the participating sites, 8840 women (98%) were screened for depression antepartum, and 7780 women (86%) were screened postpartum. A total of 576 women (6.5%) screened positive for probable depression; of these, 69% screened positive antepartum, and 31% screened positive postpartum (P < .01). All women who screened positive were referred for an evaluation by a mental health professional; 79% of the women were evaluated, which was more common antepartum than postpartum (83% vs 71%; P < .01). One hundred twenty-one women (21%) were not evaluated further after a positive screen; primary reasons included declining a mental health evaluation (30%) or transferring obstetric care (12%). Among women who underwent a mental health evaluation, 67% were diagnosed with major depression; 37% were diagnosed with an anxiety disorder; 28% were diagnosed concurrently with major depression and an anxiety disorder; 76% were diagnosed with either depression or anxiety, and 35% were treated with an antidepressant medication, which was more frequent during the postpartum period than during the antepartum period (54% vs 28%; P < .001). After adjustment for maternal age, parity, race, and household income, women who screened positive antepartum were significantly more likely to link to mental health services compared with women who screened positive postpartum (adjusted odds ratio, 2.09; 95% CI, 1.24-3.24; P = .001).

CONCLUSION

This study demonstrates the feasibility of universal depression screening during both the antepartum and postpartum periods with the use of the Edinburgh Postnatal Depression Scale as an initial screen followed by mental health referral for further diagnostic evaluation and treatment. The population of women who screened positive and who accepted additional services differed at the 2 time points, which reinforces the utility of screening during both the antepartum and postpartum periods. Although universal screening for depression is feasible, further study of the barriers to mental health evaluation and treatment and the impact of treatment on obstetric outcomes are needed.

Oxytocin, Postnatal Depression, and Parenting: A Systematic Review

OBJECTIVE

To carry out a systematic review exploring the interconnections between oxytocin, postnatal depression (PND), and parenting. Questions include: (1) How does PND affect parenting? (2) How does oxytocin affect parenting? (3) How does oxytocin affect PND?

METHODOLOGY

To review English articles in major medical databases.

RESULTS

Compared to nondepressed controls, mothers with PND interact with their infants less sensitively, report feeling less competent, and less often choose recommended practical-parenting strategies. Psychological interventions for mothers with PND generally have positive effects on mother-infant interactions. The administration of oxytocin in community samples tends to improve parental behaviors. Findings exploring the association between oxytocin and PND were inconsistent, with some evidence that oxytocin has a negative impact on mood.

CONCLUSIONS

Oxytocin is potentially useful in improving parental behaviors of mothers with PND, but more research is needed to establish its safety because of the uncertain impact of OT on maternal mood.

Enhancing Participation in Depression Care in Outpatient Perinatal Care Settings: A Systematic Review

OBJECTIVE

To examine a wide range of study designs and outcomes to estimate the extent to which interventions in outpatient perinatal care settings are associated with an increase in the uptake of depression care.

DATA SOURCES

PubMed, CINAHL, PsycINFO, ClinicalTrials.gov, and Scopus (EMBASE) were searched for studies published between 1999 and 2014 that evaluated mental health care use after screening for depression in perinatal care settings.

METHODS OF STUDY SELECTION

Inclusion criteria were: 1) English language; 2) pregnant and postpartum women who screened positive for depression; 3) exposure (validated depression screening in outpatient perinatal care setting); and, 4) outcome (mental health care use). Searches yielded 392 articles, 42 met criteria for full-text review, and 17 met inclusion criteria. Study quality was assessed using a modified Downs and Black scale.

TABULATION, INTEGRATION, AND RESULTS

Articles were independently reviewed by two abstractors and consensus reached. Study design, intervention components, and mental health care use were defined and categorized. Seventeen articles representing a range of study designs, including one randomized controlled trial and one cluster randomized controlled trial, were included. The average quality rating was 61% (31.0-90.0%). When no intervention was in place, an average of 22% (13.8-33.0%) of women who screened positive for depression had at least one mental health visit. The average rate of mental health care use was associated with a doubling of this rate with patient engagement strategies (44%, 29.0-90.0%), on-site assessments (49%, 25.2-90.0%), and perinatal care provider training (54%, 1.0-90.0%). High rates of mental health care use (81%, 72.0-90.0%) were associated with implementation of additional interventions, including resource provision to women, perinatal care provider training, on-site assessment, and access to mental health consultation for perinatal care providers.

CONCLUSION

Screening alone was associated with 22% mental health care use among women who screened positive for depression; however, implementation of additional interventions was associated with a two to fourfold increased use of mental health care. Although definitive studies are still needed, screening done in conjunction with interventions that target patient, health care provider, and practice-level barriers is associated with increased improved rates of depression detection, assessment, referral, and treatment in perinatal care settings.

The impact of routine assessment of past or current mental health on help-seeking in the perinatal period

BACKGROUND

Clinical practice guidelines now recommend that women be asked about their past or current mental health as a routine component of maternity care. However, the value of this line of enquiry in increasing engagement with support services, as required, remains controversial.

AIM

The current study aimed to examine whether assessment of past or current mental health, received with or without referral for additional support, is associated with help-seeking during pregnancy and the postpartum.

METHODS

A subsample of women drawn from the Australian Longitudinal Study on Women's Health (young cohort) who reported experiencing significant emotional distress during pregnancy (N=398) or in the 12 months following birth (N=380) participated in the study.

RESULTS

Multivariate analysis showed that women who were not asked about their emotional health were less likely to seek any formal help during both pregnancy (adjOR=0.09, 95%CI: 0.04-0.24) and the postpartum (adjOR=0.07, 95%CI: 0.02-0.13), as were women who were asked about these issues but who were not referred for additional support (antenatal: adjOR=0.26, 95%CI: 0.15-0.45; postnatal: adjOR=0.14, 95%CI: 0.07-0.27). However, considerable levels of consultation with general practitioners, midwives and child health nurses, even in the absence of referral, were evident.

CONCLUSION

This study demonstrates that enquiry by a health professional about women's past or current mental health is associated with help-seeking throughout the perinatal period. The clinical and resource implications of these findings for the primary health care sector should be considered prior to the implementation of future routine perinatal depression screening or psychosocial assessment programmes.

Depression screening and patient outcomes in pregnancy or postpartum: a systematic review

OBJECTIVE

Clinical practice guidelines disagree on whether health care professionals should screen women for depression during pregnancy or postpartum. The objective of this systematic review was to determine whether depression screening improves depression outcomes among women during pregnancy or the postpartum period.

METHODS

Searches included the CINAHL, EMBASE, ISI, MEDLINE, and PsycINFO databases through April 1, 2013; manual journal searches; reference list reviews; citation tracking of included articles; and trial registry reviews. RCTs in any language that compared depression outcomes between women during pregnancy or postpartum randomized to undergo depression screening versus women not screened were eligible.

RESULTS

There were 9,242 unique titles/abstracts and 15 full-text articles reviewed. Only 1 RCT of screening postpartum was included, but none during pregnancy. The eligible postpartum study evaluated screening in mothers in Hong Kong with 2-month-old babies (N=462) and reported a standardized mean difference for symptoms of depression at 6 months postpartum of 0.34 (95% confidence interval=0.15 to 0.52, P<0.001). Standardized mean difference per 44 additional women treated in the intervention trial arm compared to the non-screening arm was approximately 1.8. Risk of bias was high, however, because the status of outcome measures was changed post-hoc and because the reported effect size per woman treated was 6-7 times the effect sizes reported in comparable depression care interventions.

CONCLUSION

There is currently no evidence from any well-designed and conducted RCT that screening for depression would benefit women in pregnancy or postpartum. Existing guidelines that recommend depression screening during pregnancy or postpartum should be re-considered.

Postpartum depression and HIV infection among women in Malawi

BACKGROUND

HIV-infected women face several risk factors related to postpartum depression (PPD). We aimed to describe the prevalence and cumulative incidence of PPD in the low-income setting of Malawi and to determine the association between maternal and infant HIV and PPD.

METHODS

This longitudinal cohort study included 156 HIV-uninfected and 373 HIV-infected Malawian women enrolled 10-14 weeks after delivery who returned at 6, 9, 12, 15, and 18 months for follow-up visits. PPD was assessed at all visits. The prevalence of PPD at all visits was estimated using the Edinburgh Postnatal Depression Scale (EPDS). Association between PPD at 10-14 weeks and maternal and infant HIV status was assessed using log binomial regression. Cumulative incidence of PPD was assessed using Kaplan-Meier curves.

RESULTS

Prevalence of PPD was highest (11%) at 10-14 weeks postpartum and decreased to 2.9% at 18 months. There was no association between maternal HIV status and PPD (prevalence ratio, 1.18; 95% confidence interval: 0.68 to 2.08). Among HIV-infected women, prevalence of PPD was higher among women whose infants had acquired HIV (prevalence ratio, 2.0; 95% confidence interval: 1.1 to 3.6). The cumulative probability of experiencing PPD over the first 12 months postpartum was estimated to be 33.5% for HIV-infected mothers with HIV-infected infants vs. 22.5% for HIV-infected mothers with uninfected infants and 23.2% for HIV-uninfected mothers.

CONCLUSIONS

PPD prevalence did not differ between HIV-infected and -uninfected mothers but increased among women with an HIV-infected infant. Our findings suggest that it may be important to monitor PPD among women with HIV-infected infants.

Study protocol for a randomized, controlled, superiority trial comparing the clinical and cost- effectiveness of integrated online mental health assessment-referral-care in pregnancy to usual prenatal care on prenatal and postnatal mental health and infant health and development: the Integrated Maternal Psychosocial Assessment to Care Trial (IMPACT)

BACKGROUND

Stress, depression, and anxiety affect 15 to 25% of pregnant women. However, fewer than 20% of prenatal care providers assess and treat mental health problems and fewer than 20% of pregnant women seek mental healthcare. For those who seek treatment, the lack of health system integration and existing barriers frequently prevent treatment access. Without treatment, poor prenatal mental health can persist for years and impact future maternal, child, and family well-being.

METHODS/DESIGN

The purpose of this randomized controlled trial is to evaluate the effectiveness of an integrated process of online psychosocial assessment, referral, and cognitive behavior therapy (CBT) for pregnant women compared to usual prenatal care (no formal screening or specialized care). The primary outcome is self-reported prenatal depression, anxiety, and stress symptoms at 6 to 8 weeks postrandomization. Secondary outcomes are postpartum depression, anxiety, and stress symptoms; self-efficacy; mastery; self-esteem; sleep; relationship quality; coping; resilience; Apgar score; gestational age; birth weight; maternal-infant attachment; infant behavior and development; parenting stress/competence; and intervention cost-effectiveness, efficiency, feasibility, and acceptability. Pregnant women are eligible if they: 1) are <28 weeks gestation; 2) speak/read English; 3) are willing to complete email questionnaires; 4) have no, low, or moderate psychosocial risk on screening at recruitment; and 5) are eligible for CBT. A sample of 816 women will be recruited from large, urban primary care clinics and allocation is by computer-generated randomization. Women in the intervention group will complete an online psychosocial assessment, and those with mild or moderate depression, anxiety, or stress symptoms then complete six interactive cognitive behavior therapy modules. All women will complete email questionnaires at 6 to 8 weeks postrandomization and at 3, 6, and 12 months postpartum. Clinic-based providers and researchers conducting chart abstraction and analysis are blinded. Qualitative interviews with 8 to 10 healthcare providers and 15 to 30 intervention group women will provide data on feasibility and acceptability of the intervention. Results of this trial will determine the feasibility and effectiveness of an integrated approach to prenatal mental healthcare and the use of highly accessible computer-based psychosocial assessment and CBT on maternal, infant, and family-based outcomes.

TRIAL REGISTRATION

ClinicalTrials.gov Identifier: NCT01901796.

There are no randomized controlled trials that support the United States Preventive Services Task Force Guideline on screening for depression in primary care: a systematic review

BACKGROUND

The United States Preventive Services Task Force (USPSTF) recommends screening adults for depression in primary care settings when staff-assisted depression management programs are available. This recommendation, however, is based on evidence from depression management programs conducted with patients already identified as depressed, even though screening is intended to identify depressed patients not already recognized or treated. The objective of this systematic review was to evaluate whether there is evidence from randomized controlled trials (RCTs) that depression screening benefits patients in primary care, using an explicit definition of screening.

METHODS

We re-evaluated RCTs included in the 2009 USPSTF evidence review on depression screening, including only trials that compared depression outcomes between screened and non-screened patients and met the following three criteria: determined patient eligibility and randomized prior to screening; excluded patients already diagnosed with a recent episode of depression or already being treated for depression; and provided the same level of depression treatment services to patients identified as depressed in the screening and non-screening trial arms. We also reviewed studies included in a recent Cochrane systematic review, but not the USPSTF review; conducted a focused search to update the USPSTF review; and reviewed trial registries.

RESULTS

Of the nine RCTs included in the USPSTF review, four fulfilled none of three criteria for a test of depression screening, four fulfilled one of three criteria, and one fulfilled two of three criteria. There were two additional RCTs included only in the Cochrane review, and each fulfilled one of three criteria. No eligible RCTs were found via the updated review.

CONCLUSIONS

The USPSTF recommendation to screen adults for depression in primary care settings when staff-assisted depression management programs are available is not supported by evidence from any RCTs that are directly relevant to the recommendation. The USPSTF should re-evaluate this recommendation. Please see related article: http://www.biomedcentral.com/1741-7015/12/14 REGISTRATION: PROSPERO (#CRD42013004276).

The EPDS-Lifetime: assessment of lifetime prevalence and risk factors for perinatal depression in a large cohort of depressed women

Perinatal depression (PND) is a common complication of pregnancy and postpartum associated with significant morbidity. We had three goals: (1) to explore the performance of a new lifetime version of the Edinburgh Postnatal Depression Scale (EPDS-Lifetime) to assess lifetime prevalence of PND; (2) to assess prevalence of lifetime PND in women with prior histories of major depressive episode (MDE); and (3) to evaluate risk factors for PND. Subjects were from the Netherlands Study of Depression and Anxiety (NESDA). The EPDS was modified by adding lifetime PND screening questions, assessing worst episode, and symptom timing of onset. Of 682 women with lifetime MDD and a live birth, 276 (40.4 %) had a positive EPDS score of ≥12 consistent with PND. Women with PND more often sought professional help (p < 0.001) and received treatment (p = 0.001). Independent risk indicators for PND included younger age, higher education, high neuroticism, childhood trauma, and sexual abuse. We found that two in five parous women with a history of MDD had lifetime PND and that the PND episodes were more severe than MDD occurring outside of the perinatal period. The EPDS-Lifetime shows promise as a tool for assessing lifetime histories of PND in clinical and research settings.

Mother-child bonding at 1 year; associations with symptoms of postnatal depression and bonding in the first few weeks

Some mothers experience neutral or negative feelings toward their new infant. This study examined the association between symptoms of postnatal depression and mother-infant bonding and the persistence of these feelings over the first year. Bonding was assessed using the Mother-Infant Bonding Scale (MIBQ), at four times postnatal, "early weeks" (1-4 weeks), 9 weeks, 16 weeks and 1 year, in 50 depressed, Edinburgh Postnatal Depression scale (EPDS) ≥13 at 4 weeks post natal, and 29 non-depressed mothers. A significant association between the EPDS score at 4 weeks and bonding score at 1-4 weeks, 9 weeks, and at 1 year postnatal, χ(2)(1) = 9.85, p < 0.01, 5.44, p < 0.05 and 5.21, p < 0.05, respectively, was found, with a trend at 16 weeks. There was a strong association between bonding in the early weeks and all later time points χ(2)(1) = 17.26, p < 0.001, 7.89, p < 0.01 and 13.69, p < 0.001, respectively. Regression showed early bonding rather than early depression was the major predictor of bonding at 1 year. Women who are depressed postnatally can fail to bond well with their baby and this can persist for a year. Early identification and intervention for poor bonding is indicated.

Internet-based behavioral activation--treatment for postnatal depression (Netmums): a randomized controlled trial

BACKGROUND

Despite the high prevalence of postnatal depression (PND), few women seek help. The internet may increase timely access to treatment. We report a randomized controlled trial of a minimal intervention internet Behavioral Activation (iBA) treatment modified to address postnatal specific concerns (Postnatal-iBA).

METHODS

Women (n=910) recruited via a popular UK parenting site, Netmums.com, scoring above 12 on the Edinburgh Postnatal Depression Scale (EPDS) were randomly assigned to receive either Postnatal-iBA delivered or treatment-as-usual (TAU). We investigated the feasibility (recruitment, trial and treatment adherence) and effectiveness (depression status EPDS >12) of the intervention.

RESULTS

Recruitment was excellent; 1261 women, 961 of whom met inclusion criteria, signed up to the trial within two 2-week recruitment periods. Thirty-eight percent (343/910) of women completed the 15-week outcome assessment. Of those who completed 15-week assessment, fewer exceeded the depression cutoff in the Postnatal-iBA group (n=66/181) compared to TAU (n=91/162). Assuming all non-respondents remained depressed, the Postnatal-iBA effect was reduced.

LIMITATIONS

The study suffered from high attrition and future trials need to consider strategies for improving outcome completion. Some women reported struggles "keeping up" with the treatment.

CONCLUSIONS

A minimal support, widely accessible internet Behavioral Activation program for PND is feasible to deliver to community populations when embedded within popular parenting sites. For women who provide outcome data, postnatal-iBA offers promise as an effective treatment for PND. The addition of support may reduce women's struggles to keep pace with the treatment.

Effects of screening for psychological distress on patient outcomes in cancer: a systematic review

OBJECTIVE

Several practice guidelines recommend routine screening for psychological distress in cancer care. The objective was to evaluate the effect of screening cancer patients for psychological distress by assessing the (1) effectiveness of interventions to reduce distress among patients identified as distressed; and (2) effects of screening for distress on distress outcomes.

METHODS

CINAHL, Cochrane, EMBASE, ISI, MEDLINE, PsycINFO, and SCOPUS databases were searched through April 6, 2011 with manual searches of 45 relevant journals, reference list review, citation tracking of included articles, and trial registry reviews through June 30, 2012. Articles in any language on cancer patients were included if they (1) compared treatment for patients with psychological distress to placebo or usual care in a randomized controlled trial (RCT); or (2) assessed the effect of screening on psychological distress in a RCT.

RESULTS

There were 14 eligible RCTs for treatment of distress, and 1 RCT on the effects of screening on patient distress. Pharmacological, psychotherapy and collaborative care interventions generally reduced distress with small to moderate effects. One study investigated effects of screening for distress on psychological outcomes, and it found no improvement.

CONCLUSION

Treatment studies reported modest improvement in distress symptoms, but only a single eligible study was found on the effects of screening cancer patients for distress, and distress did not improve in screened patients versus those receiving usual care. Because of the lack of evidence of beneficial effects of screening cancer patients for distress, it is premature to recommend or mandate implementation of routine screening.

Improving maternal perinatal mental health: integrated care for all women versus screening for depression

OBJECTIVE

The objective of this article is to highlight the debate about universal routine screening and psychosocial assessment in the perinatal period, and suggest an alternative/additional approach to improving maternal perinatal mental illness.

CONCLUSIONS

Universal routine screening and psychosocial assessment in the perinatal period has been introduced in Australia despite a lack of evidence that this affects perinatal maternal morbidity. Furthermore, this approach is not designed to detect maternal illnesses such as schizophrenia, bipolar disorder, borderline personality disorder, although it is these women and their infants who have the highest rates of morbidity and mortality. We propose that any approach to improving maternal perinatal mental health should be tailored to particular situations and populations, with mental health care (inclusive of all mental illness, not just depression) integrated into, and thus a routine aspect of, maternity care provided to all women throughout the perinatal period.

Detection of antenatal depression in rural HIV-affected populations with short and ultrashort versions of the Edinburgh Postnatal Depression Scale (EPDS)

Risk of antenatal depression has been shown to be elevated in Southern Africa and can impact maternal and child outcomes, especially in the context of the Human Immunodeficiency Virus (HIV). Brief screening methods may optimize access to care during pregnancy, particularly where resources are scarce. This research evaluated shorter versions of the Edinburgh Postnatal Depression Scale (EPDS) to detect antenatal depression. This cross-sectional study at a large primary health care (PHC) facility recruited a consecutive series of 109 antenatal attendees in rural South Africa. Women were in the second half of pregnancy and completed the EPDS and Structured Clinical Interview for Depression (SCID). The recommended EPDS cutoff (≥13) was used to determine probable depression. Four versions, including the 10-item scale, seven-item depression, and novel three- and five-item versions developed through regression analysis, were evaluated using receiver operating characteristic (ROC) analysis. High numbers of women 51/109 (47 %) were depressed, most depression was chronic, and nearly half of the women were HIV positive 49/109 (45 %). The novel three-item version had improved positive predictive value (PPV) over the 10-item version and equivalent specificity to the seven-item depression subscale; the novel five-item provided the best overall performance in terms of ROC and Cronbach's reliability statistics and had improved specificity. The brevity, sensitivity, and reliability of the short and ultrashort versions could facilitate widespread community screening. The usefulness of the novel three- and five-item versions are underscored by the fact that sensitivity is important at first screening, while specificity becomes more important at higher levels of care. Replication in larger samples is required.

Postpartum Depression: Screening, Diagnosis, and Management Programs 2000 through 2010

The value and appropriateness of universal postpartum depression (PPD) screening remains controversial in the United States. To date, several PPD screening programs have been introduced and a few have been evaluated. Among those programs that have been evaluated, most report screening rates, diagnosis rates, or treatment initiation rates. Only four studies included patient outcomes such as the level of depressive symptoms at 6 to 12 months postpartum, and only two reported success in improving outcomes. Program characteristics that appear to result in low rates of diagnosis and followup after PPD screening include requirements for a formal psychiatric evaluation, the need to refer women to another site for therapy, and failure to integrate the PPD screening into the care provided at the woman's or her child's medical home. The two programs that reported improved outcomes were both self-contained within primary care and included specific followup, management, and therapy procedures. Both resulted in the need for outside referrals in less than 10% of women diagnosed with postpartum depression. Future studies should be based on the successful programs and their identified facilitators while avoiding identified barriers. To affect policies, the future program must report maternal outcomes going beyond the often reported process outcomes of screening, referral, and therapy initiation rates.

TRIPPD: a practice-based network effectiveness study of postpartum depression screening and management

PURPOSE

Postpartum depression is common but inadequately recognized and undertreated. Continuing depressive symptoms are associated with adverse outcomes for the woman, her infant, and family. We wanted to determine the effect of a practice-based training program for screening, diagnosis, and management of depression in postpartum mothers.

METHODS

In this practice-based effectiveness study, 28 practices were randomized to usual care (n = 14) or intervention (n = 14), and 2,343 women were enrolled between 5 and 12 weeks' postpartum. The intervention sites received education and tools for postpartum depression screening, diagnosis, initiation of therapy, and follow-up within their practices. Usual-care practices received a 30-minute presentation about postpartum depression. Screening information for the usual care was obtained from baseline surveys sent directly to the central site but was not available for patient care. Outcomes were based on patient-reported outcomes (level of depressive symptoms) from surveys at 6 and 12 months, plus medical record review (diagnosis and therapy initiation).

RESULTS

Among the 2,343 women enrolled, 1,897 (80.1%) provided outcome information, and were included in the analysis. Overall, 654 (34.5% of 1,897) women had elevated screening scores indicative of depression, with comparable rates in the intervention and usual-care groups. Among the 654 women with elevated postpartum depression screening scores, those in the intervention practices were more likely to receive a diagnosis (P = .0006) and therapy for postpartum depression (P = .002). They also had lower depressive symptom levels at 6 (P = .07) and 12 months' (P=.001) postpartum.

CONCLUSIONS

Primary care-based screening, diagnosis, and management improved mother's depression outcomes at 12 months. This practical approach could be implemented widely with modest resources.

Development of a prenatal psychosocial screening tool for post-partum depression and anxiety

BACKGROUND

Post-partum depression (PPD) is the most common complication of pregnancy in developed countries, affecting 10-15% of new mothers. There has been a shift in thinking less in terms of PPD per se to a broader consideration of poor mental health, including anxiety after giving birth. Some risk factors for poor mental health in the post-partum period can be identified prenatally; however prenatal screening tools developed to date have had poor sensitivity and specificity. The objective of this study was to develop a screening tool that identifies women at risk of distress, operationalized by elevated symptoms of depression and anxiety in the post-partum period using information collected in the prenatal period.

METHODS

Using data from the All Our Babies Study, a prospective cohort study of pregnant women living in Calgary, Alberta (N = 1578), we developed an integer score-based prediction rule for the prevalence of PPD, as defined as scoring 10 or higher on the Edinburgh Postnatal Depression Scale (EPDS) at 4-months postpartum.

RESULTS

The best fit model included known risk factors for PPD: depression and stress in late pregnancy, history of abuse, and poor relationship quality with partner. Comparison of the screening tool with the EPDS in late pregnancy showed that our tool had significantly better performance for sensitivity. Further validation of our tool was seen in its utility for identifying elevated symptoms of postpartum anxiety.

CONCLUSION

This research heeds the call for further development and validation work using psychosocial factors identified prenatally for identifying poor mental health in the post-partum period.

A randomized controlled trial of screening for maternal depression with a clinical decision support system

OBJECTIVE

To determine if automated screening and just in time delivery of testing and referral materials at the point of care promotes universal screening referral rates for maternal depression.

METHODS

The Child Health Improvement through Computer Automation (CHICA) system is a decision support and electronic medical record system used in our pediatric clinics. All families of patients up to 15 months of age seen between October 2007 and July 2009 were randomized to one of three groups: (1) screening questions printed on prescreener forms (PSF) completed by mothers in the waiting room with physician alerts for positive screens, (2) everything in (1) plus 'just in time' (JIT) printed materials to aid physicians, and (3) a control group where physicians were simply reminded to screen on printed physician worksheets.

RESULTS

The main outcome of interest was whether physicians suspected a diagnosis of maternal depression and referred a mother for assistance. This occurred significantly more often in both the PSF (2.4%) and JIT groups (2.4%) than in the control group (1.2%) (OR 2.06, 95% CI 1.08 to 3.93). Compared to the control group, more mothers were noted to have depressed mood in the PSF (OR 7.93, 95% CI 4.51 to 13.96) and JIT groups (OR 8.10, 95% CI 4.61 to 14.25). Similarly, compared to the control group, more mothers had signs of anhedonia in the PSF (OR 12.58, 95% CI 5.03 to 31.46) and JIT groups (OR 13.03, 95% CI 5.21 to 32.54).

CONCLUSIONS

Clinical decision support systems like CHICA can improve the screening of maternal depression.

Postnatal depression and its effects on child development: a review of evidence from low- and middle-income countries

INTRODUCTION OR BACKGROUND

It is well established that postnatal depression (PND) is prevalent in high-income countries and is associated with negative personal, family and child developmental outcomes.

SOURCES OF DATA

Here, studies on the prevalence of maternal PND in low- and middle-income countries are reviewed and a geographical prevalence map is presented. The impact of PND upon child outcomes is also reviewed.

AREAS OF AGREEMENT

The available evidence suggests that rates of PND are substantial, and in many regions, are higher than those reported for high-income countries. An association between PND and adverse child developmental outcomes was identified in many of the countries examined.

AREAS OF CONTROVERSY

Significant heterogeneity in prevalence rates and impact on child outcomes across studies means that the true extent of the disease burden is still unclear.

AREAS TIMELY FOR DEVELOPING RESEARCH

Nonetheless, there is a compelling case for the implementation of interventions to reduce the impact of PND on the quality of the mother-infant relationship and improve child outcomes.

Long-term outcomes of participants in a perinatal depression early detection program

BACKGROUND

Long-term follow-up studies are required to better understand the extent of the effectiveness of early detection programs for perinatal depression. We followed up participants in such a program to investigate the long-term depression, treatment and relationship outcomes of mothers originally identified as 'probably depressed' (screened positive).

METHODS

At 2 years postpartum all participants who had 'screened positive' (N=159) and a random sample of participants who had 'screened negative' were invited to participate in a mailed survey. Measures included: current mood; coping; access to treatment; quality of partner relationship; and mother-infant bonding.

RESULTS

Mothers originally detected as probably depressed (n=98) fared significantly worse than 'screened negative' mothers (n=101) both in terms of their higher mean depression scores (EPDS: Ms=11.0 vs. 6.4) and greater proportions categorised as probably depressed at 2 years postpartum (40% vs. 11% respectively, p<.001, phi=.33). Elevated depression symptoms at 2 years postpartum were associated with poorer partner relationships and mother-infant bonding. Moreover, there appears to be a double dose effect for women who screen positive on two occasions. Thirty-seven percent of depressed mothers did not take up treatment, frequently citing a preference for using their own resources.

LIMITATIONS

Limitations include the use of self-report measures to assess depression symptoms and mother-infant bonding. Treatment data was collected retrospectively.

CONCLUSIONS

Despite being offered treatment options, a substantial proportion of women who screened positive had poor long-term mental health and relationship outcomes. This paper discusses some of the implications for perinatal early detection and treatment programs.
