Measuring physical and mental health during pregnancy and postpartum in an Australian childbearing population - validation of the PROMIS Global Short Form

Health-related quality of life among Moroccan women after vaginal birth and cesarean section: Cross-sectional study

Background

During the postpartum period, understanding women's well-being, specifically their Health-related Quality of Life (HRQoL), is vital for comprehensive healthcare.

Objectives

Our study aims to explore the HRQoL and its associated factors in Moroccan women after vaginal birth (VB) and cesarean section (CS).

Study design

In this cross-sectional study we assessed the HRQoL and its associated factors among Moroccan women who gave birth at the provincial hospital center of Settat. We gathered data from 566 women, using the EQ-5D-5L instrument alongside questionnaires about socioeconomic and obstetrical aspects. The assessment was conducted utilizing the improved Relative to an Identified Distribution (RIDIT) approach, and we employed a multiple linear regression model to pinpoint the associated factors.

Results

A total of 566 women were included in our study. Our results revealed that the HRQoL in women who underwent CS was significantly lower than in VB women (EQ-5D index score = 0.30 ± 0.28 vs 0.61 ± 0.31; p < 0.0001). Similarly, the CS reduced the EQ-VAS score (mean difference = -10.73 ± 3.78; p < 0.0001). The CS was associated negatively with problems in mobility (ARI = 55 % [42-67], p < 0.0001), autonomy (ARI = 67 % [57-80], p < 0.0001), and usual activities (ARI = 56 % [42-69], p < 0.0001). Also, CS was associated with pain/discomfort (ARI = 47 % [34-60], p < 0.0001) and anxiety/depression (ARI = 3 % [-5.8-12.6], p = 0.31). The women who had birth complications had the worst HRQoL (EQ-5D index score = 0.32) compared to those who had no complications (EQ-5D index score = 0.56). Likewise, women who had postpartum complications had the worst HRQoL (EQ-5D index score = 0.39 vs EQ-5D index score = 0.54).

Conclusion

The results highlighted that mode of birth, childbirth complications, and postpartum complications are strongly associated with women's HRQoL. The EQ-5D-5L dimensions were affected after delivery. Hence, there is a requirement to create specialized initiatives for overseeing postpartum HRQoL, aiming to enhance the quality of maternal healthcare.

Psychometric properties and general population reference values for PROMIS Global Health in Hungary

OBJECTIVES

Patient-Reported Outcomes Measurement Information System-Global Health (PROMIS-GH) is a widely used generic measure of health status. This study aimed to (1) assess the psychometric properties of the Hungarian PROMIS-GH and to (2) develop general population reference values in Hungary.

METHODS

An online cross-sectional survey was conducted among the Hungarian adult general population (n = 1700). Respondents completed the PROMIS-GH v1.2. Unidimensionality (confirmatory factor analysis and bifactor model), local independence, monotonicity (Mokken scaling), graded response model fit, item characteristic curves and measurement invariance were examined. Spearman's correlations were used to analyse convergent validity of PROMIS-GH subscales with SF-36v1 composites and subscales. Age- and gender-weighted T-scores were computed for the Global Physical Health (GPH) and Global Mental Health (GMH) subscales using the US item calibrations.

RESULTS

The item response theory assumptions of unidimensionality, local independence and monotonicity were met for both subscales. The graded response model showed acceptable fit indices for both subscales. No differential item functioning was detected for any sociodemographic characteristics. GMH T-scores showed a strong correlation with SF-36 mental health composite score (rs = 0.71) and GPH T-scores with SF-36 physical health composite score (rs = 0.83). Mean GPH and GMH T-scores of females were lower (47.8 and 46.4) compared to males (50.5 and 49.3) (p < 0.001), and both mean GPH and GMH T-scores decreased with age, suggesting worse health status (p < 0.05).

CONCLUSION

This study established the validity and developed general population reference values for the PROMIS-GH in Hungary. Population reference values facilitate the interpretation of patients' scores and allow inter-country comparisons.

PROMs and PREMs in routine perinatal care: mixed methods evaluation of their implementation into integrated obstetric care networks

BACKGROUND

In the transition towards value-based healthcare, patient-reported outcome and experience measures (PROM and PREM) are recommended by international collaborations and government programs to guide clinical practice and quality improvement. For many conditions, using PROM/PREM over the complete continuum of care requires implementation across care organizations and disciplines. Along PROM/PREM implementation in obstetric care networks (OCN), we aimed to evaluate implementation outcomes and the processes influencing these outcomes in the complex context of care networks across the continuum of perinatal care.

METHODS

Three OCN in the Netherlands implemented PROM/PREM in routine practice, using an internationally developed outcomes set with care professionals and patient advocates. Their aim was to use PROM/PREM results individually to guide patient-specific care decisions and at group-level to improve quality of care. The implementation process was designed following the principles of action research: iteratively planning implementation, action, data generation and reflection to refine subsequent actions, involving both researchers and care professionals. During the one-year implementation period in each OCN, implementation outcomes and processes were evaluated in this mixed-methods study. Data generation (including observation, surveys and focus groups) and analysis were guided by two theoretical implementation frameworks: the Normalization Process Theory and Proctor's taxonomy for implementation outcomes. Qualitative findings were supplemented with survey data to solidify findings in a broader group of care professionals.

RESULTS

Care professionals in OCN found the use of PROM/PREM acceptable and appropriate, recognized their benefits and felt facilitated in their patient-centered goals and vision. However, feasibility for daily practice was low, mainly due to IT issues and time constraints. Hence PROM/PREM implementation did not sustain, but strategies for future PROM/PREM implementation were formulated in all OCN. Processes contributing positively to implementation outcomes were internalization (understand the value) and initiation (driven by key-participants), whereas challenges in relational integration (maintain confidence) and reconfiguration (refine activities) affected implementation negatively.

CONCLUSION

Although implementation did not sustain, network-broad PROM/PREM use in clinic and quality improvement matched professionals' motivation. This study provides recommendations to implement PROM/PREM meaningfully in practice in ways that support professionals in their drive towards patient-centered care. In order for PROM/PREM to fulfill their potential for value-based healthcare, our work highlights the need for sustainable IT infrastructures, as well as an iterative approach to refine their complex implementation into local contexts.

Patient-reported outcome and experience measures for quality improvement in pregnancy and childbirth care: a retrospective cohort study

BACKGROUND

Patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) can highlight issues that remain unnoticed when using standard clinical quality indicators. However, estimations of the potential power of measuring PROMs and PREMs to identify unrecognised areas suitable for quality improvement are often limited by a lack of reliable real-world data. Here, we report on how the indicator set for PROMs and PREMs that was recently developed by the International Consortium for Health Outcome Measures can change perspectives on quality assessment in women receiving care for pregnancy and childbirth.

METHODS

PROMs and PREMs were captured 6 months after childbirth via an online survey in a single academic maternity unit in the Netherlands between 2018 and 2019. Indicators of abnormality were scored using predefined cut-off values established by a national consensus group. We used regression analysis to identify associations between PROMs, PREMs and healthcare use, and further stratified data to explore the distribution of indicators among relevant patient subgroups.

RESULTS

Of 2775 questionnaires, 645 were completed and linked to medical health records. Despite only 5% of women reporting overall dissatisfaction with care, suboptimal scores were often found; in birth experience for 32% of the population, and 42% who experienced painful sexual intercourse. Subgroup analysis further revealed associations with relevant indicators of quality of care; inadequate pain relief among women with preterm birth (OR 8.8), pain with sexual intercourse among women undergoing vaginal assisted delivery (OR 2.2) and women living in a deprived area had problematic birth experiences (coefficient -3.2).

CONCLUSION

Use of PROMs and PREMs in pregnancy and childbirth care provides new insights on quality of care, resulting in potentially actionable targets for improvement not normally identified with standard clinical quality indicators. Implementation strategies and follow-up are needed to act on these findings.

Improving perinatal sleep via a scalable cognitive behavioural intervention: findings from a randomised controlled trial from pregnancy to 2 years postpartum

BACKGROUND

Sleep disturbance is common in gestational parents during pregnancy and postpartum periods. This study evaluated the feasibility and efficacy of a scalable cognitive behavioural therapy (CBT) sleep intervention tailored for these periods.

METHODS

This is a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Nulliparous females without severe medical/psychiatric conditions were randomised 1:1 to CBT or attention- and time-matched control. All participants received a 1 h telephone session and automated multimedia emails from the third trimester until 6 months postpartum. Outcomes were assessed with validated instruments at gestation weeks 30 (baseline) and 35 (pregnancy endpoint), and postpartum months 1.5, 3, 6 (postpartum endpoint), 12 and 24.

RESULTS

In total, 163 eligible participants (age M ± s.d. = 33.35 ± 3.42) were randomised. The CBT intervention was well accepted, with no reported adverse effect. Intention-to-treat analyses showed that compared to control, receiving CBT was associated with lower insomnia severity and sleep disturbance (two primary outcomes), and lower sleep-related impairment at the pregnancy endpoint (p values ⩽ 0.001), as well as at 24 months postpartum (p ranges 0.012-0.052). Group differences across the first postpartum year were non-significant. Participants with elevated insomnia symptoms at baseline benefitted substantially more from CBT (v. control), including having significantly lower insomnia symptoms throughout the first postpartum year. Group differences in symptoms of depression or anxiety were non-significant.

CONCLUSIONS

A scalable CBT sleep intervention is efficacious in buffering against sleep disturbance during pregnancy and benefitted sleep at 2-year postpartum, especially for individuals with insomnia symptoms during pregnancy. The intervention holds promise for implementation into routine perinatal care.

Dietary changes among pregnant individuals compared to pre-pandemic: A cross-sectional analysis of the Pregnancy during the COVID-19 Pandemic (PdP) study

Introduction

Dietary changes are common in pregnancy and may affect pregnancy outcomes, yet these changes and the associated contributory factors during the COVID-19 pandemic have been understudied. We aimed to investigate the association between dietary change and socioeconomic variables, pre-pregnancy BMI, and mental health symptoms; the change in intake of seven food categories and their reasons; and the association between intake of these food categories and mental health symptoms.

Materials and methods

In this cross-sectional analysis, we used data from the Pregnancy during the COVID-19 Pandemic (PdP) cohort study that collected data from pregnant Canadian individuals (n = 9,870, gestational age ≤ 35 weeks) on socioeconomic factors, pandemic-related hardships, pre-pregnancy body mass index (BMI), dietary changes compared to pre-pandemic and the reasons for these changes. We assessed depressive and anxiety symptoms using the Edinburgh Postpartum Depression Scale (EPDS) and Patient-Reported Outcomes Measurement Information System (PROMIS)-Anxiety, respectively.

Results

54.3% of the participants reported a change in their diet. Non-white ethnicity (OR = 1.33), job loss (OR = 1.29), clinically elevated depressive and anxiety symptoms (OR = 1.26 and 1.14, respectively), self-isolation (OR = 1.20), pre-pregnancy BMI (OR = 1.19), fear of COVID-19 (OR = 1.15), and pandemic phase at enrolment (OR = 0.90) significantly predicted dietary change. Most participants ate about the same amounts of dairy, meats and canned foods/dried goods as pre-pandemic (61.5, 61.7, and 60.2%, respectively), increased their intake of fresh vegetables/fruits and sweets/snacks (43.2 and 54.5%, respectively), and decreased fast-food and take-out/home delivery (53.2 and 43.1%, respectively). Changes in consumption of the food categories had a curvilinear association with mental health symptoms (except resilience) indicating greater symptoms with either decreased or increased intakes. Changes in craving, having more time for cooking/preparing foods, and being unable to go grocery shopping frequently (but not reduced affordability) were the main reasons driving these dietary changes.

Conclusion

Some factors increase the odds of dietary change among pregnant individuals during the pandemic, with some changes toward a healthy and others toward an unhealthy diet. Given the importance of a healthy diet during gestation, identifying the risk and protective factors might be the first essential step in reducing the detrimental effects of unfavorable dietary changes during the pandemic on this vulnerable population.

Patient-reported outcome measures evaluating postpartum maternal health and well-being: a systematic review and evaluation of measurement properties

OBJECTIVE

This study aimed to systematically review and evaluate postpartum health and well-being using patient-reported outcome measures across all domains of postpartum health using the COnsensus-based Standards for the selection of health Measurement INstruments guidelines.

DATA SOURCES

Based on a preprepared published protocol, a systematic search of PubMed, Embase, and CINAHL was undertaken to identify patient-reported outcome tools. The protocol was registered with the International Prospective Register of Systematic Reviews (registration number CRD42021283472), and this work followed the COnsensus-based Standards for the selection of health Measurement INstruments guidelines for systematic reviews.

STUDY ELIGIBILITY CRITERIA

Studies eligible for inclusion included those that assessed a patient-reported outcome measure examining postpartum women's health and well-being with no limitation on the domain. The included studies aimed to evaluate one or more measurement properties of the patient-reported outcome measure.

METHODS

Data extraction and the methodological assessment of the quality of the patient-reported outcome measure were assessed by 2 reviewers independently based on content validity, structural validity, internal consistency, cross-cultural validity or measurement invariance, reliability, measurement error, hypotheses testing for construct validity, and responsiveness, as defined by the COnsensus-based Standards for the selection of health Measurement INstruments. The standard used for content validity were the domains of importance to women in postpartum health and well-being proposed by the International Consortium for Health Outcomes Measurement. The outcome domains for patient-reported health status include mental health, health-related quality of life, incontinence, pain with intercourse, breastfeeding, and motherhood role transition. The quality of the methods was rated an overall rating of results, awarded a level of evidence, and assessed using the Grading of Recommendations, Assessment, Development, and Evaluations assessment tool, and a level of recommendation was awarded for each tool.

RESULTS

There were 10,324 studies identified in the initial search, of which 29 tools were identified from 41 eligible studies included in the review. Moreover, 21 tools were awarded an "A" grading of recommendation for use as a patient-reported outcome measure in postpartum women following the COnsensus-based Standards for the selection of health Measurement Instruments standards. Of the "A"-rated tools, 17 (80%) examined the domain of mental health, 5 examined health-related quality of life, 4 examined breastfeeding, and 6 represented role transition. No "A"-recommended tool examined postpartum incontinence or pain with intercourse. Of note, 3 tools did not cover domains as recommended by the International Consortium for Health Outcomes Measurement, and 5 tools were awarded a "B" rating, requiring more research before their recommendation for use. Here, most tools were awarded very low-moderate Recommendations, Assessment, Development, and Evaluations level of evidence. Moreover, the highest quality tool identified that covered multiple domains of postpartum health and well-being was the women's Postpartum Quality-of-Life Questionnaire.

CONCLUSION

This systematic review identified the best performing patient-reported outcome measures to assess postpartum health and well-being. No individual tool covers all 6 domains of postpartum health and well-being. Here, the highest quality tool found that covered multiple domains of postpartum health and well-being was the Postpartum Quality-of-Life Questionnaire. The Postpartum Quality-of-Life Questionnaire captures 4 of 6 domains of importance to women, with domains of incontinence and sexual health unevaluated. The domain of urinary incontinence was represented by the International Consultation on Incontinence Questionnaire Short Form, which requires further psychometric analysis before its recommended use. Postpartum sexual health, not represented by any tool, necessitates the development of a patient-reported outcome measure. A postpartum patient-reported outcome measure would be best provided by a combination of tools; however, further research is required before its implementation.

Quality of Life instruments and their psychometric properties for use in parents during pregnancy and the postpartum period: a systematic scoping review

Purpose

To identify instruments used to measure parents’ Quality of Life (QoL) during pregnancy and the postpartum period, and to describe their characteristics and psychometric properties.

Methods

For this scoping review we conducted systematic literature searches in MEDLINE, EMBASE, PsychINFO, CINAHL and HaPI in mid-December 2020, to identify studies evaluating psychometric properties. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) were used to define and categorize psychometric properties. Two reviewers screened the studies independently, and customized screening questions were used to assess eligibility against inclusion criteria. Data were systematically extracted into a predesigned data charting matrix, and descriptively analyzed.

Results

The searches identified 5671 studies, of which 53 studies met the inclusion criteria. In total, there were 19 QoL instruments: 12 generic and seven period specific. The most reported instruments were SF-36, SF-12 and WHOQOL-BREF, and the most evaluated instruments were SF-12, WHOQOL-BREF, QOL-GRAV, and PQOL. We found that none of the identified instruments had been evaluated for all nine psychometric properties recommended by the COSMIN. The most reported psychometric properties were internal consistency and structural validity. The instruments were primarily assessed in parents residing in Asia (50%), and 83% of the studies were conducted from 2010 to 2020. Only three studies included psychometric measures assessed on fathers.

Conclusion

Our review shows there is extensive evidence on the internal consistency and structural validity of QoL instruments used on parents during pregnancy and the postpartum period, but that the evidence on other psychometric properties is sparse. Validation studies and primary studies are needed to provide evidence on the reliability, validity, responsiveness, and interpretability of QoL instruments for this target group, in particular for fathers and partners.

Patient-Reported Outcome and Experience Measures in Perinatal Care to Guide Clinical Practice: Prospective Observational Study

Background

The International Consortium for Health Outcomes Measurement has published a set of patient-centered outcome measures for pregnancy and childbirth (PCB set), including patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs). To establish value-based pregnancy and childbirth care, the PCB set was implemented in the Netherlands, using the outcomes on the patient level for shared decision-making and on an aggregated level for quality improvement.

Objective

This study aims to report first outcomes, experiences, and practice insights of implementing the PCB set in clinical practice.

Methods

In total, 7 obstetric care networks across the Netherlands, each consisting of 1 or 2 hospitals and multiple community midwifery practices (ranging in number from 2 to 18), implemented the PROM and PREM domains of the PCB set as part of clinical routine. This observational study included all women participating in the clinical project. PROMs and PREMs were assessed with questionnaires at 5 time points: 2 during pregnancy and 3 post partum. Clinical threshold values (alerts) supported care professionals interpreting the answers, indicating possibly alarming outcomes per domain. Data collection took place from February 2020 to September 2021. Data analysis included missing (pattern) analysis, sum scores, alert rates, and sensitivity analysis.

Results

In total, 1923 questionnaires were collected across the 5 time points: 816 (42.43%) at T1 (first trimester), 793 (41.23%) at T2 (early third trimester), 125 (6.5%) at T3 (maternity week), 170 (8.84%) at T4 (6 weeks post partum), and 19 (1%) at T5 (6 months post partum). Of these, 84% (1615/1923) were filled out completely. Missing items per domain ranged from 0% to 13%, with the highest missing rates for depression, pain with intercourse, and experience with pain relief at birth. No notable missing patterns were found. For the PROM domains, relatively high alert rates were found both in pregnancy and post partum for incontinence (469/1798, 26.08%), pain with intercourse (229/1005, 22.79%), breastfeeding self-efficacy (175/765, 22.88%), and mother-child bonding (122/288, 42.36%). Regarding the PREM domains, the highest alert rates were found for birth experience (37/170, 21.76%), shared decision-making (101/982, 10.29%), and discussing pain relief ante partum (310/793, 39.09%). Some domains showed very little clinical variation; for example, role of the mother and satisfaction with care.

Conclusions

The PCB set is a useful tool to assess patient-reported outcomes and experiences that need to be addressed over the whole course of pregnancy and childbirth. Our results provide opportunities to improve and personalize perinatal care. Furthermore, we could propose several recommendations regarding methods and timeline of measurements based on our findings. This study supports the implementation of the PCB set in clinical practice, thereby advancing the transformation toward patient-centered, value-based health care for pregnancy and childbirth.

An exploration of potential output measures to assess efficiency and productivity for labour and birth in Australia

Background

In maternity services, as in other areas of healthcare, increasing emphasis is placed on improving “efficiency” or “productivity”. The first step in any efficiency and productivity analysis is the selection of relevant input and output measures. Within healthcare quantifying what is produced (outputs) can be difficult.

The aim of this paper is to identify a potential output measure, that can be used in an assessment of the efficiency and productivity of labour and birth in-hospital care in Australia and to assess the extent to which it reflects the principles of woman-centred care.

Methods

This paper will survey available perinatal and maternal datasets in Australia to identify potential output measures; map identified output variables against the principles of woman-centred care outlined in Australia’s national maternity strategy; and based on this, create a preliminary composite outcome measure for use in assessing the efficiency and productivity of Australian maternity services.

Results

There are significant gaps in Australia’s maternity data collections with regard to measuring how well a maternity service is performing against the values of respect, choice and access; however safety is well measured. Our proposed composite measure identified that of the 63,215 births in Queensland in 2014, 67% met the criteria of quality outlined in our composite measure.

Conclusions

Adoption in Australia of the collection of woman-reported maternity outcomes would substantially strengthen Australia’s national maternity data collections and provide a more holistic view of pregnancy and childbirth in Australia beyond traditional measure of maternal and neonate morbidity and mortality. Such measures to capture respect, choice and access could complement existing safety measures to inform the assessment of productivity and efficiency in maternity care.

Cost-effectiveness of public caseload midwifery compared to standard care in an Australian setting: a pragmatic analysis to inform service delivery

BACKGROUND

Decision-makers need quantifiable data on costs and outcomes to determine the optimal mix of antenatal models of care to offer. This study aimed to examine the cost utility of a publicly funded Midwifery Group Practice (MGP) caseload model of care compared to other models of care and demonstrate the feasibility of conducting such an analysis to inform service decision-making.

OBJECTIVE

To provide a methodological framework to determine the value of public midwifery in different settings.

METHODS

Incremental costs and incremental utility (health gains measured in quality-adjusted life years (QALYs)) of public MGP caseload were compared to other models of care currently offered at a large tertiary hospital in Australia. Patient Reported Outcomes Measurement Information System Global Short Form scores were converted into utility values by mapping to the EuroQol 5 dimensions and then converting to QALYs. Costs were assessed from a health system funder's point of view.

RESULTS

There were 85 women in the public MGP caseload care group and 72 received other models of care. Unadjusted total mean cost for mothers' and babies' health service use from study entry to 12 months post-partum was $27 618 for MGP caseload care and $33 608 for other models of care. After adjusting for clinical and demographic differences between groups, total costs were 22% higher (cost ratio: 1.218, P = 0.04) for other models of maternity care. When considering costs to all funders, public MGP caseload care cost $5208 less than other models of care. There was no significant difference in QALY between the two groups (difference: 0.010, 95% CI: -0.038, 0.018).

CONCLUSION

Public MGP caseload care costs 22% less than other models of care, after accounting for differences in baseline characteristics between groups. There were no significant differences in QALYs. Public MGP caseload care produced comparable health outcomes, with some indication that outcomes may be better for lower cost per woman.

A Community-enabled Readiness for first 1000 Days Learning Ecosystem (CRADLE) for first-time families: study protocol of a three-arm randomised controlled trial

Background

Enhanced parenting self-efficacy (PSE) contributes to positive parenting and future parental-child health. First-time parents, in particular, are in need of support since the pregnancy until post-delivery to strengthen their early PSE. However, there is a lack of effective and sustainable relevant programmes in the community. The Community-enabled Readiness for first 1000 Days Learning Ecosystem (CRADLE) aims to develop a self-learning eco-community throughout the pregnancy and early childhood to promote PSE among first-time parents. We apply choice architecture strategy using behavioural nudges and midwife-led continuity care during the first 1000 days, and test their effects on PSE and mother-child health for first-time families in Singapore.

Methods

This three-arm randomised controlled trial will recruit up to 750 pregnant women from the KK Women’s and Children’s Hospital, Singapore. Participants will be randomly assigned to receive: (1) standard routine care; (2) behavioural nudges (text messages) along with the use of a social media platform; or (3) midwife-led continuity care involving individualised teleconferencing sessions, during pregnancy and post-delivery. Using web-based questionnaires, participants will be assessed for baseline socio-demography and health status in the first visit, with follow-up assessments in the third trimester, at birth, 6-week (primary end-point), 6-, 12-, 18- and 24-month post-delivery. The primary outcome is PSE. Secondary outcomes include health and birth experience, mental wellness, feeding practice, maternal and child nutritional status. Intention-to-treat and per-protocol analyses will be performed using general linear models to test the effects of interventions across three arms. Recruitment has begun in June 2020 and is estimated to complete in September 2022.

Discussion

This study may identify a sustainable effective strategy in the community by helping first-time parents to have a positive experience during the pregnancy, childbirth and parenthood, leading to an enhanced PSE and health outcomes for both mother and child. Findings from this study will provide insight into the implementation of early parenting and mother-child care programmes.

Implementation of a standard outcome set in perinatal care: a qualitative analysis of barriers and facilitators from all stakeholder perspectives

BACKGROUND

To improve their quality, healthcare systems are increasingly focused on value delivered to patients. For perinatal care, the International Consortium for Health Outcomes Measurement (ICHOM) proposed a patient-centred outcome set with both clinical and patient-reported measures for pregnancy and childbirth (PCB set). This study aimed to identify factors that affect the implementation of the PCB set at the pre-implementation stage, using the consolidated framework for implementation research (CFIR).

METHODS

In this qualitative study, we conducted semi-structured interviews amongst a purposive sample of key stakeholders within an obstetric care network (OCN): 1) patients, 2) perinatal care professionals involved in the full cycle of perinatal care, and 3) policy makers, including hospital managers, administrative staff and health care insurers. While the CFIR guided data capture and structuring, thematic analysis revealed overarching themes that best reflected the barriers and facilitators from different stakeholder perspectives. Within these overarching themes, the CFIR constructs were maintained.

RESULTS

Interviews were conducted with 6 patients, 16 professionals and 5 policy makers. Thematic analysis supported by the CFIR framework identified four main themes: the instrument and its implementation process, use in individual patient care, use in quality improvement, and the context of the OCN. Important barriers included professional workload, data reliability, and interprofessional and interorganizational collaboration. Potential facilitators were the PCB set's direct value in individual care, interprofessional feedback and education, and aligning with existing systems. Prominent variations between stakeholder groups included the expected patient burden, the level of use, transparency of outcomes and the degree of integrated care.

CONCLUSIONS

This study clarified critical factors that affect successful implementation of the PCB set in perinatal care. Practice recommendations, suggested at multiple levels, can enable structural patient-centred care improvement and may unite stakeholders towards integrated birth care.

Single Item Measure of Social Supports: Evaluation of construct validity during pregnancy

BACKGROUND

Lack of social support during pregnancy is associated with psychosocial vulnerability. The Single Item Measure of Social Supports (SIMSS) is included in a core outcome set to facilitate case-adjustment based on social support. Validity of the SIMSS has not been evaluated in childbearing women. We aimed to evaluate the construct validity of the SIMSS during pregnancy. Secondary aim was to evaluate an alternative short-measure of social support.

METHODS

Recruited women (n = 309) attending antenatal care were invited to complete the SIMSS, Multidimensional Scale of Perceived Social Support (MSPSS), Antenatal Risk Questionnaire (ANRQ), and Edinburgh Postnatal Depression Scale (EPDS). Convergent validity of SIMSS with MSPSS and hypothesis testing for psychosocial risk and depressive symptoms were conducted.

RESULTS

Correlations were moderate between the SIMSS and MSPSS (r_s = .35), but weak between the SIMSS and EPDS (r_s = -.18); and SIMSS and ANRQ (r_s = -.22). In contrast, correlations were moderate between the MSPSS and EPDS (r_s = -.39) and ANRQ (r_s = -.45). A shortened 3-item version of the MSPSS showed good psychometric properties and internal consistency reliability (a = .86).

LIMITATIONS

Findings relate to one Australian birthing sample during pregnancy. Replication of this study in larger, diverse maternity populations, including postpartum is recommended.

CONCLUSIONS

The SIMSS is a poor measure of social support during pregnancy with poor predictive ability to detect maternal vulnerability including depression and psychosocial risk. A revised 3-item version of the MSPSS was found to be a valid and reliable measure of social support.

Comparison of screening accuracy of the Patient Health Questionnaire-2 using two case-identification methods during pregnancy and postpartum

BACKGROUND

Variation exists regarding perinatal depression screening. A two-step screening method has been recommended. According to a maternity-focused core outcome set developed by the International Consortium for Health Outcomes Measurement, women who score 3 or more on the PHQ-2 then complete the Edinburgh Postnatal Depression Scale (EPDS). Limited evidence exists regarding the screening accuracy of the PHQ-2 in childbearing women. An alternative case-identification method may be more sensitive for perinatal women. We aimed to [1] evaluate the screening accuracy of the PHQ-2 during the perinatal period using two case-identification methods, and [2] measure the variability of accuracy over four time-points during pregnancy and postpartum.

METHODS

A prospective, longitudinal cohort study was conducted with 309 consecutive women who completed the PHQ-2 and EPDS during pregnancy (booking, 36-weeks) and postpartum (6-, 26-weeks). EPDS was the reference standard using cut-off scores for 'at least probable minor depression' during pregnancy (≥ 13) and postpartum (≥ 10) and for 'probable major depression' during pregnancy (≥ 15) and postpartum (≥ 13). PHQ-2 was analysed using two methods: [1] scored (cut-points ≥ 2 and ≥ 3), [2] dichotomous yes/no (positive response to either question) against EPDS cut-points for at least probable minor and probable major depression. Receiver operating characteristic analyses determined accuracy.

RESULTS

Probable major depression: Over four timepoints PHQ-2 ≥ 3 revealed lowest sensitivity (36-79%) but highest specificity (94-98%). An alternative case-identification method revealed high sensitivity (93-100%), but lowest specificity (58-71%). Minor depression: PHQ-2 ≥ 3 revealed the lowest sensitivity (19-50%) but highest specificity (95-98%). An alternative case-identification method revealed the highest sensitivity (81-100%) and moderate specificity (60-74%).

CONCLUSIONS

Recommended method of case-identification (PHQ-2 ≥ 3) missed an unacceptable number of women at-risk of depression. As a clinical decision-making tool, an alternative, dichotomous method maximized case-identification and is recommended. Further, the literature identified inconsistent reporting of the PHQ-2 and the alternative case-identification method hindering the ability to synthesise data. The future use and reporting of consistent question wording and response format will improve outcome reporting and synthesis. Further research in larger and diverse maternity populations is recommended.
