Screening for postnatal depression: not a simple task

Postnatal depression screening in a paediatric primary care setting in Italy

BACKGROUND

Postnatal depression is a non-psychotic depressive disorder that begins within 4 weeks of childbirth and occurs in 13% of mothers and 10% of fathers. A prospective study with the aim to evaluate the prevalence of postnatal depression by screening parents with the Edinburgh Postnatal Depression Scale (EPDS) in the Italian paediatric primary care setting was performed.

METHODS

Mothers and fathers of infants born between 1 February and 31 July 2012, living in Italy's Milan-1 local health unit area, represented the target population of this pilot study. Parents attending well-child visits at any of the family paediatricians' offices between 60 to 90 days postpartum were asked to participate in the screening and to fill out the EPDS questionnaire. A cut-off score of 12 was used to identify parents with postnatal depression symptoms. Maternal and paternal socio-demographic variables and information concerning pregnancy and delivery were also collected. To investigate the association between screening positivity (dependent variable) and socio-demographic variables and factors related to pregnancy and delivery, a Pearson's χ2 test was used. Moreover, a stepwise multivariate logistic regression was carried out to evaluate the risk factors that most influence the probability of suffering from postnatal depression.

RESULTS

In all, 126 out of 2706 (4.7%, 95% CI 3.9-5.5%) mothers and 24 out of 1420 (1.7%, 95% CI 1.0-2.4%) fathers were found to be positive for depressive symptoms. Women with mood disorders and anxiety during pregnancy were at increased risk of postpartum depression (OR 22.9, 95% CI 12.1-43.4). Only 11 mothers (8.7%) positive to EPDS screening attended a psychiatric service, and for 8 of them the diagnosis of postnatal depression was confirmed.

CONCLUSIONS

The prevalence of postnatal depression was lower than previously reported. Routine screening resulted ineffective, since few mothers found positive for depression symptoms decided to attend psychiatric services.

Postpartum Depression Screening: A Review for Psychiatrists

LEARNING OBJECTIVES

After participating in this activity, learners should be better able to:• Evaluate the rationale for screening women for postpartum depression• Assess tools for screening for postpartum depression

OBJECTIVE

To perform a qualitative literature review on screening for postpartum depression (PPD), as applicable to the general psychiatrist. Results are classified by instrument, timing, and clinical setting of the screen.

DATA SOURCES

A literature search was conducted using the PubMed database for English-language articles published since January 1987. Of the 2406 citations initially identified, 61 articles remained after application of inclusion and exclusion criteria.

RESULTS

Among numerous screening tools for PPD, the Edinburgh Postnatal Depression Scale is the most widely used. Data suggest that screening for PPD should commence soon after delivery, with subsequent screens at multiple time-points in the postpartum period. Primary care, pediatric, and obstetric settings are all viable locations for screening, but are ineffective without follow-up mental health evaluations. Less data are available to define optimal patterns either for screening in psychiatric settings or for the psychiatrist's role in managing perinatal depression.

CONCLUSIONS

The American Congress of Obstetricians and Gynecologists, American Academy of Pediatrics, and most authors firmly recommend screening for PPD. The Edinburgh Postnatal Depression Scale can be administered in various clinical settings. Screening should occur at multiple time-points throughout the first postpartum year. The psychiatrist's role in early detection and prevention of PPD requires further exploration.

Psychosocial factors and excessive gestational weight gain: The effect of parity in an Australian cohort

OBJECTIVES

psychosocial variables can be protective or risk factors for excessive gestational weight gain (GWG). Parity has also been associated with GWG; however, its effect on psychosocial risk factors for GWG is yet to be determined. The aim of this study was to investigate if, and how, psychosocial factors vary in their impact on the GWG of primiparous and multiparous women.

DESIGN/PARTICIPANTS

pregnant women were recruited in 2011 via study advertisements placed in hospitals, online, in parenting magazines, and at baby and children's markets, resulting in a sample of 256 women (113 primiparous, 143 multiparous). Participants completed questionnaires at 16-18 weeks' gestation and their pregravid BMI was recorded. Final weight before delivery was measured and used to calculate GWG.

FINDINGS

the findings revealed that primiparous women had significantly higher feelings of attractiveness (a facet of body attitude; p=0.01) than multiparous women. Hierarchical regressions revealed that in the overall sample, increased GWG was associated significantly with lower pre-pregnancy BMI (standardised coefficient β=-0.39, p<0.001), higher anxiety symptoms (β=0.25, p=0.004), and reduced self-efficacy to eat a healthy diet (β=-0.20, p=0.02). Although higher GWG was predicted significantly by decreased feelings of strength and fitness for primiparous women (β=-0.25, p=0.04) and higher anxiety was related significantly to greater GWG for multiparous women (β=0.43, p<0.001), statistical comparison of the model across the two groups suggested the magnitude of these effects did not differ across groups (p>0.05).

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

the findings suggest that psychosocial screening and interventions by healthcare professionals may help to identify women who are at risk of excessive GWG, and there may be specific psychosocial factors that are more relevant for each parity group.

Postpartum emotional support: a qualitative study of women's and men's anticipated needs and preferred sources

Australian health policy emphasises prevention, early intervention and improved pathways to treatment for perinatal mental disorders. Primary care is vital to achieving these aims. The aim of this study was to understand the anticipated needs and preferred sources of mental health information and support of men and women expecting their first baby. Nulliparous English-speaking expectant parents attending childbirth education programs in public and private hospitals participated in single sex small group discussions in late pregnancy. Discussions were audio-recorded, transcribed and analysed thematically using the group as the unit of analysis. Eight groups (22 women; 16 men) encompassing diverse socioeconomic circumstances were conducted. Analyses showed idealised fantasies consistently tempered with realistic expectations about adjustment to life with a baby. However, there were diverse and gendered views about whether primary care providers should discuss mental health with parents of infants and willingness to complete written questionnaires or be referred for specialist mental health care. Men regard primary family care as mother not father inclusive. Expectant parents readily anticipate realistic postnatal adjustment and need for emotional support. Increased provision of services that meet men's needs and public understanding and acceptance of Australian integrated models of primary postnatal mental health care are needed.

Disparities in reported psychosocial assessment across public and private maternity settings: a national survey of women in Australia

BACKGROUND

Psychosocial assessment and depression screening is now recommended for all women who are pregnant or have recently given birth in Australia. Existing studies which have examined the extent of participation by women in such population-based programs have been primarily concerned with depression screening rather than a more comprehensive examination of psychosocial assessment, and have not been sufficiently inclusive of the 30% of women whose maternity care is provided in the private sector. Whether there are disparities in equity of access to perinatal psychosocial assessment is also unknown.

METHODS

A sub-sample of women (N = 1804) drawn from the Australian Longitudinal Study on Women's Health participated in the study. Overall rates of assessment across five psychosocial domains (current emotional health; mental health history; current level of support; current drug or alcohol use; experience of domestic violence or abuse), as well as receipt of mental health promotion information, were examined. Log binomial regression was performed to investigate whether there were socio-demographic or health system inequalities among women who are and are not assessed across each domain.

RESULTS

Two-thirds of women (66.8%) reported being asked about their current emotional health in the antenatal period, increasing to 75.6% of women in the postnatal period. Rates decreased markedly for reported assessment of mental health history (52.9% during pregnancy and 41.2% postnatally). Women were least likely to be asked about their experience of domestic violence or abuse in both the antenatal and postnatal periods (in total, 35.7% and 31.8%, respectively).In terms of equity of access to psychosocial assessment, women who gave birth in the public hospital sector were more likely to report being assessed across all domains of assessment in the antenatal period, compared with women who gave birth in the private sector, after adjusting for other significant covariates. State of residence was associated with reported rates of assessment across all domains in both the antenatal and postnatal periods. Women from non-English speaking backgrounds and women with more than one child were less likely to be assessed across various domains.

CONCLUSION

This study provides an important insight into the reported overall penetration of and access to perinatal psychosocial assessment among a sample of women in Australia. Opportunities to minimise the current shortfall in assessment rates, particularly in the private sector, and for ongoing monitoring of assessment activity at a national level are discussed.

Negotiating policy in practice: child and family health nurses' approach to the process of postnatal psychosocial assessment

Background

There is growing recognition internationally of the need to identify women with risk factors for poor perinatal mental health in pregnancy and following birth. In the state of New South Wales, Australia the Supporting Families Early policy provides a framework of assessment and support for women and families and includes routine psychosocial assessment and depression screening. This study investigated the approach taken by Child and Family Health Nurses (CFHNs) following birth to assessment and screening as recommended by state policy. This was a qualitative ethnographic study that included 83 CFHN and 20 women. Observations occurred with thirteen nurses; with 20 women, in the home or the clinic environment. An additional 70 nurses participated in discussion groups. An observational tool (4D&4R) and field notes were used to record observations and analysed descriptively using frequencies. Field notes, interview data and discussion group transcripts were analysed thematically.

An additional 70 nurses participated in discussion groups. An observational tool (4D&4R) and field notes were used to record observations and analysed descriptively using frequencies. Field notes, interview data and discussion group transcripts were analysed thematically.

Results

CFHNs demonstrated a range of approaches to assessment and screening. Psychosocial assessment was conducted in 50% (10 out of the 20) of the interactions observed; however, all the women were screened using the Edinburgh Depression Scale. Four major themes that represent the approach taken to the assessment process were identified: ‘Engagement: getting that first bit right’, ‘Doing some paperwork’, ‘Creating comfort’ and ‘Psychosocial assessment: doing it another way’. Nurses utilised other skills such as observing the women interacting with their baby, taking note of non verbal communication and using intuition to develop a clinical decision.

Conclusion

Overall, nurses’ took a sensitive and caring approach to assessment and screening, however, there were differences in interpretations of the policy recommendations across the two sites. Nurses adopt a flexible, relationship-based approach to the assessment process; however, they experience tension when required to incorporate structured psychosocial assessment processes. To undertake assessment and screening effectively, CFHNs require ongoing support, training and supervision to maintain this sensitive and emotionally challenging work.

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.

Outcomes from implementing systematic antepartum depression screening in obstetrics

This study was developed to evaluate the feasibility of implementing systematic depression screening in a large obstetric practice and to evaluate the degree that detection and referral led to linkage with behavioral healthcare. Depression screening was conducted using the Edinburgh Postnatal Depression Scale, administered at the initial pregnancy care appointment. Patients at or above a predetermined score of 14 were advised to seek further behavioral health assessment through the patient's behavioral healthcare coverage. Within 4 weeks of screening, those referred were contacted by telephone, by clinic staff, to determine whether they had pursued behavioral healthcare as recommended. Limited available data for newly established postdelivery screening were similarly evaluated. All 2,199 newly presenting pregnant women who were seen in our obstetric clinics from September 2008 to May 2009 were screened for depression, and 102 (4.6%) scored at or above an EPDS of 14. Follow-up calls revealed that none had pursued further behavioral health assessments. Of these 2,199, screening and follow-up data were available for 569 women at their 6-week postdelivery visit. Of these, 28 (4.9%) were above EPDS of 14, and 5 (17.9%) reported pursuit of further behavioral healthcare following screening and referral. Peripartum depression can be addressed with systematic screening, and the electronic medical record can readily be used to monitor results. Detection and referral at the beginning of pregnancy did not lead to intended linkage with behavioral healthcare, but detection and referral postdelivery had a modest influence. Barriers to pursuing behavioral healthcare need to be discovered and addressed.

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.

The paradox of screening: rural women's views on screening for postnatal depression

BACKGROUND

Universal screening for postnatal depression is currently being promoted in Australia to assist detection and treatment of affected women, yet debate continues internationally about the effectiveness of screening. One rural shire in Victoria has been screening all women for postnatal depression at maternal and child health checks for many years. This paper explores the views of women affected by this intervention.

METHODS

A postal survey was sent to an entire one year cohort of women resident in the shire and eligible for this program [n = 230]. Women were asked whether they recalled having been screened for postnatal depression and what their experience had been, including any referrals made as a result of screening. Women interested in providing additional information were invited to give a phone number for further contact. Twenty women were interviewed in-depth about their experiences. The interview sample was selected to include both depressed and non-depressed women living in town and on rural properties, who represented the range of circumstances of women living in the shire.

RESULTS

The return rate for the postal survey was 62% [n = 147/230]. Eighty-seven women indicated that they were interested in further contact, 80 of whom were able to be reached by telephone and 20 were interviewed in-depth. Women had diverse views and experiences of screening. The EPDS proved to be a barrier for some women, and a facilitator for others, in accessing support and referrals. The mediating factor appeared to be a trusting relationship with the nurse able to communicate her concern for the woman and offer support and referrals if required.

CONCLUSIONS

Detection of maternal depression requires more than administration of a screening tool at a single time point. While this approach did work for some women, for others it actually made appropriate care and support more difficult. Rather, trained and empathic healthcare providers working in a coordinated primary care service should provide multiple and flexible opportunities for women to disclose and discuss their emotional health issues.

A national approach to perinatal mental health in Australia: exercising caution in the roll-out of a public health initiative

Perinatal depression is an important public health issue, with major consequences for the mother, child and family. Perinatal depression is often associated with anxiety and other mental health and psychosocial issues. The National Perinatal Depression Plan (NPDP) proposes routine screening during pregnancy and after birth, follow-up support for women assessed to be at risk of or experiencing depression, and training for health professionals. Identifying women at risk of or experiencing perinatal depression is difficult, and there is no standard tool used by all hospitals to assess women's emotional health and psychosocial comorbidities. The NPDP provides an opportunity to develop and evaluate new approaches to assessing perinatal depression and a range of psychosocial issues, and to test strategies for supporting women and their families before and after birth.

Obstetric care provider engagement in a perinatal depression screening program

To investigate obstetric care provider attitudes toward perinatal depression screening and factors associated with variable screening rates. Provider attitudes about depression screening were investigated via structured interviews (open-ended and rating scale questions) and analyzed using qualitative content analysis. Most providers (86%) found screening effective at identifying women at risk for perinatal depression (average rating of 8.7 on 10-point analog scale). However, 95% overestimated their own screening rates and 67% inaccurately thought they achieved universal screening. Providers not directly involved in their office-based screening process demonstrated lower average screening rates (37%) than those who maintained active involvement (59%; p = 0.07). Obstetric care providers support perinatal depression screening in the context of a program that assumes responsibility for processing screens, conducts assessments of at-risk women and provides referrals to mental health professionals. Provider participation in screening and tying screening to routine obstetric outpatient activities such as glucose tolerance testing are associated with higher screening rates.

A psychosocial risk assessment model (PRAM) for use with pregnant and postpartum women in primary care settings

Recognition of high rates of mental health morbidity and mortality that affect women during the perinatal period has prompted the development of psychosocial risk assessment programs. Designed to identify women, at risk, during routine health checks and delivered by primary care health service providers, these fit within a primary prevention and early intervention strategic approach to the reduction of perinatal mental illness and reflect an integrated approach to perinatal health services delivery. This paper describes the development and use of the psychosocial risk assessment model (PRAM) at the Royal Hospital for Women in Sydney, Australia. Data is presented on 2,142 women who attended the Antenatal Midwives Clinic between 2002 and 2005. The PRAM guides primary care staff to quickly identify women experiencing emotional distress and/or psychosocial problems during pregnancy or postnatal checks. Measures used in pregnancy are the symptom-based Edinburgh Depression Scale and the psychosocial risk-based Antenatal Risk Questionnaire. In postnatal setting the Postnatal Risk Questionnaire is used. Scores can be used to compute a Psychosocial Risk Index (PRI) to guide individualized care planning, define needs for referral and classify groups for clinical and research purposes. Based on the PRI, among 2,142 women assessed in pregnancy 70.6% were classified as low/no risk (no interventions indicated currently), 24.1% as medium risk (in need of monitoring), and 5.3% as high risk (complex). The PRAM offers a conceptual framework, methods and measures for brief psychosocial assessment with clinical and research applications. Postpartum follow up studies of women assessed during pregnancy have commenced. Randomized controlled trials and cross-cultural studies are now indicated to strengthen the evidence base for the model.
