Evaluation of Domains of Patient-Reported Outcome Measures for Recovery After Childbirth: A Scoping and Systematic Review

Health-related quality of life and utility of maternity health states amongst post-partum Australians

BACKGROUND

This study aimed to measure patient-reported health-related quality of life amongst post-partum women in Queensland, Australia.

METHODS

Patient-reported health-related quality of life data was prospectively collected from 134 post-partum women using the EQ-5D-5L at weekly intervals during the first six weeks following birth. Data across the five health domains of the EQ-5D-5L was converted to a single health utility value to represent overall health status. Linear mixed modelling and regression analysis were used to examine changes in utility over the first six weeks post-birth and determine associations between utility and clinical and demographic characteristics of post-partum women.

FINDINGS

Gestation at birth and weeks post-partum were significantly associated with utility values when considered in a multivariate linear mixed model. Mean utility values increased by 0.01 for every week increase in gestation at birth, and utility values were 0.70 at one week post-partum and increased to 0.85 at six weeks post-partum, with the largest increase occurring between one- and two-weeks post-birth. When controlling for variables that were found to predict utility values across the first six weeks post-partum, no single state of health predicted utility values at one-week post-partum.

CONCLUSIONS

Maternity services can use our data and methods to establish norms for their own service, and researchers and maternity services can partner to conduct cost-effectiveness analysis using our more relevant utility values than what is currently available. Time since birth and gestational age of the woman's baby should be considered when selecting post-partum health state utility values for maternity services cost-effectiveness analyses.

Association of inpatient postpartum recovery with patient-reported outcome measures following hospital discharge: a prospective cohort study

BACKGROUND

The relationship between the quality of inpatient versus outpatient obstetric postpartum recovery is under-explored. We examined the association between inpatient reported quality of recovery with outpatient global recovery, pain severity, pain interference, anxiety, and depression screening scores postpartum.

METHODS

We conducted a multicenter observational cohort study of women in labor who underwent vaginal, operative vaginal, or intrapartum cesarean birth. Subjects completed baseline assessments of pain, social support, anxiety, and depression in early labor. We assessed the Obstetric Quality of Recovery-10 (ObsQoR-10) on the day of discharge and the ObsQoR-10, Global Health Scale (GHVAS; 0-100), Brief Pain Inventory (BPI), and the Edinburgh Postnatal Depression Scale (EPDS) on postpartum day seven. We hypothesized that the ObsQoR-10 scores at discharge would be useful in predicting postpartum day seven measures of recovery and postpartum depression screening scores.

RESULTS

We consented 558 subjects, 551/558(98%) completed baseline assessments, 400/551(72%) completed the ObsQoR-10 tool, and 344/551(62%) completed an EPDS assessment. Median (1st, 3rd quartile) ObsQoR-10 scores were 78 (63, 90) at discharge and 85 (68,93) on postpartum day seven, (difference of 7 [99% CI 2 to 13], P < 0.001). GHVAS on postpartum day seven identified 204/344 (59%) of subjects with good recovery. An ObsQoR-10 score of > 86 at discharge had a RR of 1.5 [95% CI 1.2 to 1.8], P < 0.001 for good recovery at postpartum day seven, the EPDS identified 20/344 (5.8%) respondents with a score ≥ 13 on postpartum day seven. The area under the curve between the ObsQoR-10 at discharge with an EPDS ≥ 13 was 0.74 (99% CI 0.61 to 0.86, P < 0.001). The RR for an EPDS ≥ 13 on postpartum day seven with an ObsQoR-10 < 77 on the day of discharge was 7.8 (95% CI 1.8 to 33.8; P = 0.001).

CONCLUSIONS

ObsQoR-10 scores at discharge and postpartum day seven demonstrated increased obstetric recovery in the post-discharge period. The observed association between the ObsQoR-10 and the EPDS, suggests that the ObsQoR-10 might facilitate identification of women at increased risk of postpartum anxiety or depression. Identification of high-risk women at discharge may allow early interventions to reduce morbidity secondary to postpartum depression.

Outcomes and outcome measures utilised in randomised controlled trials of postoperative caesarean delivery pain: a scoping review

BACKGROUND

Inadequately treated postoperative pain following caesarean delivery can delay recovery and the ability to care for a newborn. Effectiveness studies of interventions to treat postoperative caesarean delivery pain measure different outcomes, limiting data pooling for meta-analysis. We performed a comprehensive review of existing outcomes with the aim of recommending core outcomes for future research.

METHODS

A scoping review to identify all outcomes reported in randomised controlled trials (RCTs) and clinical trial registries of interventions to treat or prevent postoperative caesarean delivery pain, with postoperative pain as a primary outcome measure. We searched PubMed, Web of Science, CINAHL, LILACS, Embase, CDSR and CRCT for studies from May 2016 to 2021. Outcomes were extracted and frequencies tabulated.

RESULTS

Ninety RCTs and 11 trial registries were included. In total, 392 outcomes (375 inpatient and 17 outpatient) were identified and categorised. The most reported outcome domain was analgesia (n = 242/375, 64.5%), reported in 96% of inpatient studies, with analgesic consumption accounting for 108/375, 28.8% of analgesia outcomes. The second most common domain was pain intensity (n = 120/375, 32%), reported in 97% of inpatient studies, using the visual analogue scale (68/120, 59%) and the numerical reporting scale (37/120, 25%). Maternal and neonatal adverse effects accounted for 65/375 (17.3%) and 19/375 (5.1%) of inpatient outcomes, respectively.

CONCLUSIONS

Outcomes reported in RCTs for postoperative caesarean delivery pain vary widely. The results of this review suggest that standardisation is needed to promote research efficiency and aid future meta-analyses to identify optimal postoperative caesarean delivery pain management.

Prevalence and predictors for postpartum sleep disorders: a nationwide analysis

OBJECTIVE

To describe the prevalence and predictors of postpartum sleep disorders.

DESIGN

A retrospective cohort study.

SETTING

Postpartum.

POPULATION

Commercially insured women delivering in California (USA) between 2011 and 2014.

METHODS

Using the Optum Clinformatics Datamart Database.

MAIN OUTCOME MEASURES

Prevalence of a postpartum sleep disorder diagnosis with and without a depression diagnosis up to 12 months following hospital discharge for inpatient delivery. We also identified predictors of a postpartum sleep disorder diagnosis using multivariable logistic regression.

RESULTS

We identified 3535 (1.9%) women with a postpartum sleep disorder diagnosis. The prevalence of sleep disorder diagnoses was insomnia (1.3%), sleep apnea (0.25%), and other sleep disorder (0.25%). The odds of a postpartum sleep disorder were highest among women with a history of drug abuse (adjusted odds ratio (aOR): 2.70, 95% confidence interval (CI): 1.79-4.09); a stillbirth delivery (aOR: 2.15, 95% CI: 1.53-3.01); and chronic hypertension (aOR: 1.82; 95% CI: 1.57-2.11). A comorbid diagnosis of a postpartum sleep disorder and depression occurred in 1182 women (0.6%). These women accounted for 33.4% of all women with a postpartum sleep disorder. The strongest predictors of a comorbid diagnosis were a history of drug abuse (aOR: 4.13; 95% CI: 2.37-7.21) and a stillbirth delivery (aOR: 2.93; 95% CI: 1.74-4.92).

CONCLUSIONS

Postpartum sleep disorders are underdiagnosed conditions, with only 2% of postpartum women in this cohort receiving a sleep diagnosis using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Insomnia was the most common disorder and one-third of women diagnosed with a postpartum sleep disorder had a co-morbid diagnosis of depression. Future studies are needed to improve the screening and diagnostic accuracy of postpartum sleep disorders.

Development, women-centricity and psychometric properties of maternity patient-reported outcome measures (PROMs): A systematic review

BACKGROUND

Measuring maternity care outcomes based on what women value is critical to promoting woman-centred maternity care. Patient-reported outcome measures (PROMs) are instruments that enable service users to assess healthcare service and system performance.

AIM

To identify and critically appraise the risk of bias, woman-centricity (content validity) and psychometric properties of maternity PROMs published in the scientific literature.

METHODS

MEDLINE, CINAHL Plus, PsycINFO and Embase were systematically searched for relevant records between 01/01/2010 and 07/10/2021. Included articles underwent risk of bias, content validity and psychometric properties assessments in line with COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. PROM results were summarised according to language subgroups and an overall recommendation for use was determined.

FINDINGS

Forty-four studies reported on the development and psychometric evaluation of 9 maternity PROMs, grouped into 32 language subgroups. Risk of bias assessments for the PROM development and content validity showed inadequate or doubtful methodological quality. Internal consistency reliability, hypothesis testing (for construct validity), structural validity and test-retest reliability varied markedly in sufficiency and evidence quality. No PROMs received a level 'A' recommendation, required for real-world use.

CONCLUSION

Maternity PROMs identified in this systematic review had poor quality evidence for their measurement properties and lacked sufficient content validity, indicating a lack of woman-centricity in instrument development. Future research should prioritise women's voices in deciding what is relevant, comprehensive and comprehensible to measure, as this will impact overall validity and reliability and facilitate real-world use.

A systematic review of patient-reported outcome measures used in maternal postpartum anxiety

OBJECTIVE

This study aimed to conduct a systematic review and to evaluate the psychometric measurement properties of instruments for postpartum anxiety using the Consensus-Based Standards for the Selection of Health Measurement Instruments guidelines to identify the best available patient-reported outcome measure.

DATA SOURCES

We searched 4 databases (CINAHL, Embase, PubMed, and Web of Science in July 2022) and included studies that evaluated at least 1 psychometric measurement property of a patient-reported outcome measurement instrument. The protocol was registered with the International Prospective Register for Systematic Reviews under identifier CRD42021260004 and followed the Consensus-Based Standards for the Selection of Health Measurement Instruments guidelines for systematic reviews.

STUDY ELIGIBILITY

Studies eligible for inclusion were those that assessed the performance of a patient-reported outcome measure for screening for postpartum anxiety. We included studies in which the instruments were subjected to some form of psychometric property assessment in the postpartum maternal population, consisted of at least 2 questions, and were not subscales.

METHODS

This systematic review used the Consensus-Based Standards for the Selection of Health Measurement Instruments and the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify the best patient-reported outcome measurement instrument for examining postpartum anxiety. A risk of bias assessment was performed, and a modified GRADE approach was used to assess the level of evidence with recommendations being made for the overall quality of each instrument.

RESULTS

A total of 28 studies evaluating 13 instruments in 10,570 patients were included. Content validity was sufficient in 9 with 5 instruments receiving a class A recommendation (recommended for use). The Postpartum Specific Anxiety Scale, Postpartum Specific Anxiety Scale Research Short Form, Postpartum Specific Anxiety Scale Research Short Form Covid, Postpartum Specific Anxiety Scale-Persian, and the State-Trait Anxiety Inventory demonstrated adequate content validity and sufficient internal consistency. Nine instruments received a recommendation of class B (further research required). No instrument received a class C recommendation (not recommended for use).

CONCLUSION

Five instruments received a class A recommendation, all with limitations, such as not being specific to the postpartum population, not assessing all domains, lacking generalizability, or evaluation of cross-cultural validity. There is currently no freely available instrument that assess all domains of postpartum anxiety. Future studies are needed to determine the optimum current instrument or to develop and validate a more specific measure for maternal postpartum anxiety.

Postpartum recovery of nulliparous women following scheduled cesarean delivery and spontaneous vaginal delivery: a prospective observational study

BACKGROUND

Inpatient postpartum recovery trajectories following cesarean delivery and spontaneous vaginal delivery are underexplored.

OBJECTIVE

This study primarily aimed to compare recovery following cesarean delivery and spontaneous vaginal delivery in the first postpartum week, and secondarily to evaluate psychometrically the Japanese version of the Obstetric Quality of Recovery-10 scoring tool.

STUDY DESIGN

Following institutional review board approval, the EQ-5D-3L (EuroQoL 5-Dimension 3-Level) questionnaire and a Japanese version of the Obstetric Quality of Recovery-10 measure were used to evaluate inpatient postpartum recovery in uncomplicated nulliparous parturients delivering via scheduled cesarean delivery or spontaneous vaginal delivery.

RESULTS

A total of 48 and 50 women who delivered via cesarean delivery and spontaneous vaginal delivery, respectively, were recruited. Women delivering via scheduled cesarean delivery experienced significantly worse quality of recovery on days 1 and 2 compared with those who had spontaneous vaginal delivery. Quality of recovery significantly improved daily, plateauing at days 4 and 3 for cesarean delivery and spontaneous vaginal delivery groups, respectively. Compared with cesarean delivery, spontaneous vaginal delivery was associated with prolonged time to analgesia requirement, decreased opioid consumption, reduced antiemetic requirement, and reduced times to liquid/solid intake, ambulation, and discharge. Obstetric Quality of Recovery-10-Japanese is a valid (correlates with the EQ-5D-3L including a global health visual analog scale, gestational age, blood loss, opioid consumption, time until first analgesic request, liquid/solid intake, ambulation, catheter removal, and discharge), reliable (Cronbach alpha=0.88; Spearman-Brown reliability estimate=0.94; and intraclass correlation coefficient=0.89), and clinically feasible (98% 24-hour response rate) measure.

CONCLUSION

Inpatient postpartum recovery is significantly better in the first 2 postpartum days following spontaneous vaginal delivery compared with scheduled cesarean delivery. Inpatient recovery is largely achieved within 4 and 3 days following scheduled cesarean delivery and spontaneous vaginal delivery, respectively. Obstetric Quality of Recovery-10-Japanese is a valid, reliable, and feasible measure of inpatient postpartum recovery.

Postpartum Home Blood Pressure Monitoring: A Systematic Review

OBJECTIVE

To assess the effectiveness of postpartum home blood pressure (BP) monitoring compared with clinic-based follow-up and the comparative effectiveness of alternative home BP-monitoring regimens.

DATA SOURCES

Search of Medline, Cochrane, EMBASE, CINAHL, and ClinicalTrials.gov from inception to December 1, 2022, searching for home BP monitoring in postpartum individuals.

METHODS OF STUDY SELECTION

We included randomized controlled trials (RCTs), nonrandomized comparative studies, and single-arm studies that evaluated the effects of postpartum home BP monitoring (up to 1 year), with or without telemonitoring, on postpartum maternal and infant outcomes, health care utilization, and harm outcomes. After double screening, we extracted demographics and outcomes to SRDR+.

TABULATION, INTEGRATION, AND RESULTS

Thirteen studies (three RCTs, two nonrandomized comparative studies, and eight single-arm studies) met eligibility criteria. All comparative studies enrolled participants with a diagnosis of hypertensive disorders of pregnancy. One RCT compared home BP monitoring with bidirectional text messaging with scheduled clinic-based BP visits, finding an increased likelihood that at least one BP measurement was ascertained during the first 10 days postpartum for participants in the home BP-monitoring arm (relative risk 2.11, 95% CI 1.68-2.65). One nonrandomized comparative study reported a similar effect (adjusted relative risk [aRR] 1.59, 95% CI 1.36-1.77). Home BP monitoring was not associated with the rate of BP treatment initiation (aRR 1.03, 95% CI 0.74-1.44) but was associated with reduced unplanned hypertension-related hospital admissions (aRR 0.12, 95% CI 0.01-0.96). Most patients (83.3-87.0%) were satisfied with management related to home BP monitoring. Home BP monitoring, compared with office-based follow-up, was associated with reduced racial disparities in BP ascertainment by approximately 50%.

CONCLUSION

Home BP monitoring likely improves ascertainment of BP, which is necessary for early recognition of hypertension in postpartum individuals, and may compensate for racial disparities in office-based follow-up. There is insufficient evidence to conclude that home BP monitoring reduces severe maternal morbidity or mortality or reduces racial disparities in clinical outcomes.

Measuring enhanced recovery in obstetrics: a narrative review

Enhanced recovery after cesarean delivery is a protocolized approach to perioperative care, with the aim to optimize maternal recovery after surgery. It is associated with improved maternal and neonatal outcomes, including decreased length of hospital stay, opioid consumption, pain scores, complications, increased maternal satisfaction, and increased breastfeeding success. However, the pace and enthusiasm of adoption of enhanced recovery after cesarean delivery internationally has not yet been matched with high-quality evidence demonstrating its benefit, and current studies provide low- to very low-quality evidence in support of enhanced recovery after cesarean delivery. This article provides a summary of current measures of enhanced recovery after cesarean delivery success, and optimal measures of inpatient and outpatient postpartum recovery. We summarize outcomes from 22 published enhanced recovery after cesarean delivery implementation studies and 2 meta-analyses. A variety of disparate metrics have been used to measure enhanced recovery after cesarean delivery success, including process measures (length of hospital stay, bundle compliance, preoperative fasting time, time to first mobilization, time to urinary catheter removal), maternal outcomes (patient-reported outcome measures, complications, opioid consumption, satisfaction), neonatal outcomes (breastfeeding success, Apgar scores, maternal-neonatal bonding), cost savings, and complication rates (maternal readmission rate, urinary recatheterization rate, neonatal readmission rate). A core outcome set for use in enhanced recovery after cesarean delivery studies has been developed through Delphi consensus, involving stakeholders including obstetricians, anesthesiologists, patients, and a midwife. Fifteen measures covering key aspects of enhanced recovery after cesarean delivery adoption are recommended for use in future enhanced recovery after cesarean delivery implementation studies. The use of these outcome measures could improve the quality of evidence surrounding enhanced recovery after cesarean delivery. Using evidence-based evaluation guidelines developed by the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) group, the Obstetric Quality of Recovery score (ObsQoR) was identified as the best patient-reported outcome measure for inpatient postpartum recovery. Advances in our understanding of postpartum recovery as a multidimensional and dynamic construct have opened new avenues for the identification of optimum patient-reported outcome measures in this context. The use of standardized measures such as these will facilitate pooling of data in future studies and improve overall levels of evidence surrounding enhanced recovery after cesarean delivery. Larger studies with optimal study designs, using recommended outcomes including patient-reported outcome measures, will reduce variation and improve data quality to help guide future recommendations.

Maternal Functioning and Psychological Distress During the COVID-19 Pandemic

Background: Our objective was to understand maternal functioning and psychological distress among mothers of young children in the United States during April/May 2020, early in the coronavirus disease 2019 (COVID-19) pandemic. Materials and Methods: Participants were 862 moms of children aged 0-3 years old who completed an online survey. We examined maternal functioning (maternal competency and self-care subscales from the Barkin Index of Maternal Functioning) and psychological distress (depression, anxiety, and stress subscales of the DASS-21), and then examined interaction effects of COVID-19 impact and socioeconomic status (SES; represented by income and education). Results: Mothers' reports of higher maternal functioning correlated with lower psychological distress and both sets of factors varied substantially by SES and COVID-19 Impact. Higher COVID-19 Impact was associated with lower functioning and greater distress. Higher income and education were associated with better maternal self-care, but not maternal competency. Although we expected high SES to buffer mothers from a higher impact of COVID-19, we found that mothers with high SES reported a lower level of maternal competence and more stress than low-SES mothers. Interactions between COVID-19 impact and SES predicting maternal functioning and psychological distress revealed that when COVID-19 impact was low, high SES was associated with high functioning scores and less distress. Conclusions: This work challenges the assumptions that a stressful event will be uniformly experienced by mothers of young children as well as the stress-buffering role of higher SES. This study highlights the importance of considering SES when characterizing maternal functioning and psychological distress during times of high stress. Further research is needed to examine the processes contributing to these discrepancies.

Dangers associated with assuming robustness of scale reliability and validity: Psychometric properties of the Barkin Index of Maternal Functioning with Ethiopian mothers

This study was conducted to assess the psychometric properties of the Barkin Index of Maternal Functioning (BIMF) in an Ethiopian context. Data were obtained from 202 women with a child less than 1 year of age. Narrow standard deviations characterized responses to most BIMF items, but a handful of items had wider standard deviations associated with bimodality. Most interitem correlations were < |.15|, and 13 of the 20 BIMF items did not load satisfactorily on any factor in exploratory factor analyses. Two factors emerged from the remaining items, one with three items and the other with four. Although poor reliability results relating to internal (interitem) and temporal consistency could be attributed to limited variability in the data, a number of concerns are raised about the BIMF itself, including its content validity, instructions, response options, and usefulness in healthcare settings. Suggestions are made for improving the assessment of maternal functioning in Ethiopia and other contexts. More generally, this research demonstrates that researchers should not assume that the psychometric properties and appropriateness of scales will remain robust when those scales are used in contexts that differ from the contexts in which they were created.

The impact of implementing patient-reported measures in routine maternity care: a systematic review

INTRODUCTION

While there is growing interest in applying patient-reported measures (PRMs) in clinical routine, limited collective evidence of the impact of PRMs hinder their widespread use in specific contexts, such as maternity care. Our objective was to synthesize existing emperical evidence on the impact of implementing PRMs in routine maternity care.

MATERIAL AND METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines (version 2020). We electronically searched six databases for the literature on the implementation of PRMs in maternity care. A multi-level (woman, clinical, organizational, national and societal) analytic framework for analyzing and synthesizing emperically proven impacts of PRMs was developed. Quality was assessed using the Mixed Method Appraisal Tool. The GRADE-CERQual approach was used to assess the confidence in the review findings and arguments. The protocol was registered in PROSPERO (CRD42021234501).

RESULTS

Overall, 4971 articles were screened. The emperical evidence, collected from 11 relevant studies, showed that the use of PRMs in routine maternity care could produce positive effects on clinical process (assessment and detection of health problems, clinical visit preparation, resource use, woman-professional communication, decision-making, woman-professional relationship, and care quality), and health behavior and outcomes (women's health and wellbeing, quality of life, health behavior, experiences and satisfaction with healthcare services), awareness, engagement and self-management of own health, and disclosure of health issues. The confidence in the review findings was low to moderate due to a limited number of studies, inadequate data and methodological limitations of included studies.

CONCLUSIONS

The limited emperical evidence available suggested that the use of PRMs may have positive effects at the individual health level and clinical process level. However, the evidence was not strong enough to provide policy recommendations on the use of PRMs in routine maternity care. This review revealed limitations of currently available research, such as lack of generalizability and narrow scopes in investigating impact. Efforts are needed to improve the quality of research on the use of PRMs in routine maternity care by widening the study population, including different types of PRMs, and considering the effects of PRMs at different levels and domains of healthcare.

Development and validation of a Portuguese version of Obstetric Quality of Recovery-10 (ObsQoR-10-Portuguese)

BACKGROUND

We aimed to develop and validate a Portuguese version of the Obstetric Quality of Recovery-10 (ObsQoR-10-Portuguese) patient-reported outcome measure and evaluate its psychometric properties.

METHODS

After ethical approval, we recruited term pregnant women undergoing uncomplicated elective cesarean delivery in a single Brazilian institution. Women were invited to complete the translated ObsQoR-10-Portuguese and EuroQoL (EQ-5D) questionnaires (including a global health visual analog scale [GHVAS]) at 24 h (±6 h) following delivery, and a subset of women an hour later. We assessed validity and reliability of ObsQoR-10-Portuguese.

RESULTS

One hundred thirteen enrolled women completed the surveys at 24 h and 29 women at 25 h (100% response rate).

VALIDITY

(i) convergent validity: ObsQoR-10-Portuguese correlated moderately with EuroQoL score (r = -0.587) and GHVAS score (r = 0.568) at 24 h. (ii) Discriminant validity: ObsQoR-10 discriminated well between good versus poor recovery (GHVAS score ≥ 70 versus < 70; difference in mean scores 14.2; p < 0.001). (iii) Hypothesis testing: 24-h ObsQoR-10-Portuguese scores correlated with gestational age (r = 0.191; p = 0.043). (iv) Cross-cultural validity: differential item functioning analysis suggested bias in 2 items. Reliability: (i) internal consistency was good (Cronbach's alpha = 0.82 and inter-item correlation = 0.31). (ii) Split-half reliability was very good (Spearman-Brown Prophesy Reliability Estimate = 0.80). (iii) Test re-test reliability was excellent (intra-class correlation coefficient = 0.87). (iv) Floor and ceiling effects: < 5% women scored either 0 or 100 (lowest and highest scores, respectively).

CONCLUSION

ObsQoR-10-Portuguese is valid and reliable, and should be considered for use in Portuguese-speaking women to assess their quality of inpatient recovery following cesarean delivery.

Assessment of Patient-Reported Outcome Measures for Maternal Postpartum Depression Using the Consensus-Based Standards for the Selection of Health Measurement Instruments Guideline: A Systematic Review

IMPORTANCE

Maternal depression is frequently reported in the postpartum period, with an estimated prevalence of approximately 15% during the first postpartum year. Despite the high prevalence of postpartum depression, there is no consensus regarding which patient-reported outcome measure (PROM) should be used to screen for this complex, multidimensional construct.

OBJECTIVE

To evaluate psychometric measurement properties of existing PROMs of maternal postpartum depression using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guideline and identify the best available patient-reported screening measure.

EVIDENCE REVIEW

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. PubMed, CINAHL, Embase, and Web of Science were searched on July 1, 2019, for validated PROMs of postpartum depression, and an additional search including a hand search of references from eligible studies was conducted in June 2021. Included studies evaluated 1 or more psychometric measurement properties of the identified PROMs. A risk-of-bias assessment was performed to evaluate methods of each included study. Psychometric measurement properties of each PROM were rated according to COSMIN criteria. A modified Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the level of evidence supporting each rating, and a recommendation class (A, recommended for use; B, further research required; or C, not recommended) was given based on the overall quality of each included PROM.

FINDINGS

Among 10 264 postpartum recovery studies, 27 PROMs were identified. Ten PROMs (37.0%) met the inclusion criteria and were used in 43 studies (0.4%) involving 22 095 postpartum women. At least 1 psychometric measurement property was assessed for each of the 10 validated PROMs identified. Content validity was sufficient in all PROMs. The Edinburgh Postnatal Depression Scale (EPDS) demonstrated adequate content validity and a moderate level of evidence for sufficient internal consistency (with sufficient structural validity), resulting in a recommendation of class A. The other 9 PROMs evaluated received a recommendation of class B.

CONCLUSIONS AND RELEVANCE

The findings of this systematic review suggest that the EPDS is the best available patient-reported screening measure of maternal postpartum depression. Future studies should focus on evaluating the cross-cultural validity, reliability, and measurement error of the EPDS to improve understanding of its psychometric properties and utility.

Expert Consensus Regarding Core Outcomes for Enhanced Recovery after Cesarean Delivery Studies: A Delphi study

BACKGROUND

Heterogeneity among reported outcomes from enhanced recovery after cesarean delivery impact studies is high. This study aimed to develop a standardized enhanced recovery core outcome set for use in future enhanced recovery after cesarean delivery studies.

METHODS

An international consensus study involving physicians, patients and a director of Midwifery and Nursing Services, was conducted using a three-round modified Delphi approach (2 rounds of electronic questionnaires and a 3rd round e-discussion), to produce the core outcome set. An initial list of outcomes was based on a previously published systematic review. Consensus was obtained for the final core outcome set, including definitions for key terms, and preferred units of measurement. Strong consensus was defined as ≥70% agreement and weak consensus as 50-69% agreement. Of the 64 stakeholders who were approached, 32 agreed to participate. All 32, 31 and 26 stakeholders completed Rounds 1, 2 and 3, respectively.

RESULTS

The number of outcomes in the final core outcome set was reduced from 98 to 15. Strong consensus (≥70% stakeholder agreement) was achieved for 15 outcomes. The core outcome set included: length of hospital stay; compliance with enhanced recovery protocol; maternal morbidity (hospital re-admissions or unplanned consultations); provision of optimal analgesia (maternal satisfaction, compliance with analgesia, opioid consumption / requirement and incidence of nausea or vomiting); fasting times; breastfeeding success; and times to mobilization and urinary catheter removal. The Obstetric Quality of Recovery-10 item composite measure was also included in the final core outcome set. Areas identified as requiring further research included readiness for discharge and analysis of cost savings.

CONCLUSIONS

Results from an international consensus to develop a core outcome set for enhanced recovery after cesarean delivery are presented. These are outcomes that could be considered when designing future enhanced recovery studies.

Evaluating the development, woman-centricity and psychometric properties of maternity patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs): A systematic review protocol

INTRODUCTION

Woman-centred care is the right of every woman receiving maternity care, irrespective of where care is being received and who is providing care. This protocol describes a planned systematic review that will identify, describe and critically appraise the psychometric properties of maternity patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs). The woman-centricity of PROM and PREM development and content validation (ie, the extent to which women were involved in these processes) will also be assessed. This information will be used to develop a maternity PROMs and PREMs database to support service and system performance measurement, and value-based maternity care initiatives.

METHODS AND ANALYSIS

This study will be guided by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews of outcome measurement instruments. Studies identified via MEDLINE, CINAHL Plus, PsycINFO and EMBASE describing the development, content validation and/or psychometric evaluation of PROMs and PREMs specifically designed for maternity populations throughout pregnancy, childbirth and postnatal periods will be considered if published from 2010 onward, in English, and available in full text. The COSMIN risk of bias checklist will be used to evaluate the quality of studies reporting on the development, content validation and/or psychometric evaluation of PROMs and PREMs. COSMIN criteria for good content validity will be used to assess the woman-centricity of PROM and PREM development and content validation studies. COSMIN standards of good psychometric properties will be used to evaluate the validity and reliability of the identified instruments.

ETHICS AND DISSEMINATION

Ethical permission for this research is not required. The findings of this research will be submitted for publication in an international, peer-reviewed journal. Abstracts for national and international conference presentations will also be submitted. The proposed maternity PROMs and PREMs database will be freely accessible online, and developed with consumer input to ensure its usefulness to a range of maternity care stakeholders.

Validation of translated Obstetric Quality of Recovery (ObsQoR-10A) score after nonelective cesarean delivery (CD) in an Arabic-speaking population

Background:

The ObsQoR-11 is a validated scale that assesses recovery after cesarean delivery (CD). This observational study aimed to evaluate the psychometric properties of its Arabic version.

Methods:

The original ObsQoR-11 was translated into an Arabic version (ObsQoR-10A). All participants completed the ObsQoR-10A at 24 h and 48 h postoperatively after CD. Validity, reliability, responsiveness, and feasibility were assessed.

Results:

The ObsQoR-10A correlated with Global Health Numerical Rating Scale (NRS) at 24 h (R = 0.68, 95% CI: 0.56–0.80, P < 0.001) and at 48 h (R = 0.66, 95% CI: 0.54–0.78, P < 0.001) and differentiated between good and poor recovery (median scores at 24 h 88 vs. 71, P < 0.001; at 48 h 95.5 vs. 70, P < 0.001). ObsQoR-10A correlated with hospital length of stay at 24 h (R = −0.21, 95% CI: −0.40 to −0.02, P = 0.03) and at 48 h (R = −0.21, 95% CI: −0.40 to −0.03, P = 0.02); gestational age at 24 h (R = 0.22, 95% CI: 0.03–0.40, P = 0.02); change in hemoglobin at 24 h (R = −0.30, 95% CI: 0.51 to −0.10, P < 0.01); and total opioids at 48 h (R = −0.45, 95% CI: −0.62 to −0.27, P < 0.001). There was a significant difference between 24 h and 48 h postoperative ObsQoR-10A scores (median difference: −18; P < 0.001 which shows responsiveness). Other key measures included a Cronbach's alpha of 0.87, split-half 0.75, and intra-class correlation >0.62 with no floor or ceiling effects. Median (IQR) completion time was 3 (3-5) and 3 (2.5-3.5) minutes at 24 h and 48 h.

Conclusions:

ObsQoR-10A is a valid, reliable, responsive, and a clinically feasible tool in an Arabic-speaking obstetric population.

Impact of enhanced recovery after cesarean delivery on maternal outcomes: A systematic review and meta-analysis

BACKGROUND

This meta-analysis explores the impact of enhanced recovery after cesarean delivery (ERAC) on maternal outcomes.

METHODS

We searched 4 databases (Web of Science, Embase, PubMed and CINAHL) in October 2020 without date limiters, for studies quantitatively comparing ERAC implementation to a control group. The primary outcome was length of hospital stay and secondary outcomes included time to mobilization and time to urinary catheter removal, opioid consumption, readmission rates and cost savings. Mean differences and odds ratios (MD and OR with 95% confidence intervals) were calculated. Levels of evidence were assessed using GRADE.

RESULTS

Twelve studies involving 17,607 patients (9693 without ERAC and 7914 with ERAC) were included. ERAC was associated with reduced: length of hospital stay (MD -0.51 days [-0.94, -0.09]; p = 0.018; I2 = 99%), time to first mobilization (MD -11.05 h [-18.64, -3.46]; p = 0.004; I2 = 98%), time to urinary catheter removal (MD -13.19 h [-17.59, -8.79]; p < 0.001; I2 = 97%) and opioid consumption (MD -21.85 mg morphine equivalents [-33.19, -10.50]; p = < 0.001; I2 = 91%), with no difference in maternal readmission rate (OR 1.23 [0.96, 1.57]; p = 0.10; I2 = 0%). Three studies reported cost savings associated with ERAC. The GRADE levels of evidence were rated as low or very low quality for all study outcomes.

CONCLUSION

ERAC is associated with reduction in length of stay, times to first mobilization and urinary catheter removal and opioid consumption. ERAC does not significantly affect maternal hospital readmission rates following discharge. Further studies are required to determine which ERAC interventions to implement and which outcomes best determine ERAC efficacy.

Proposed domains for assessing postpartum recovery: a concept elicitation study

OBJECTIVE

To propose postpartum recovery domains.

DESIGN

Concept elicitation study.

SETTING

Semi-structured interviews.

POPULATION

Ten writing committee members and 50 stakeholder interviews (23 postpartum women, nine general obstetricians, five maternal and fetal medicine specialists, eight nurses and five obstetric anaesthetists).

METHODS

Alternating interviews and focus group meetings until concept saturation was achieved (no new themes discussed in three consecutive interviews). Interviews were digitally recorded and transcribed, and an iterative coding process was used to identify domains.

MAIN OUTCOME MEASURES

The primary outcome was to identify recovery domains. We also report key symptoms and concerns. Discussion frequency and importance scores (0-100; 0 = not important; 100 = vitally important to recovery) were used to rank domains. Discussion frequency was used to rank factors helping and hindering recovery, and to determine the greatest challenges experienced postpartum.

RESULTS

Thirty-four interviews and two focus group meetings were performed. The 13 postpartum recovery domains identified, (ranked highest to lowest) were: psychosocial distress, surgical/medical factors, infant feeding and breast health, psychosocial support, pain, physical function, sleep, motherhood experience, infant health, fatigue, appearance, sexual function and cognition. The most frequently discussed factors facilitating postpartum recovery were: family support, lactation/breastfeeding support and partner support. The most frequently discussed factor hindering recovery was inadequate social support. The most frequent challenges reported were: breastfeeding (week 1), breastfeeding (week 3) and sleep (week 6).

CONCLUSIONS

We propose 13 domains that comprehensively describe recovery in women delivering in a single centre within the USA. This provides a novel framework to study the postpartum recovery process.

TWEETABLE ABSTRACT

We propose 13 postpartum recovery domains that provide a framework to study the recovery process following childbirth.

Perinatal depression

PURPOSE OF REVIEW

Perinatal depression is a common and debilitating complication of pregnancy and childbirth. Recent studies have elucidated relationships between acute birth events on depression risk, and novel treatments for postpartum depression have been discovered and approved. This article reviews current understandings about birth events on depression, new screening standards, and novel treatments for postpartum depression.

RECENT FINDINGS

Pain, analgesia, and depression are complex traits that are inter-related during and after pregnancy. Certain individuals may benefit more than others from addressing pain and suffering around childbirth. Exposures to general anesthesia or postdural puncture headache are associated with postpartum depression symptoms, although a causal relationship is unlikely. Brexanolone, ketamine and its related compounds, and nonpharmacologic options offer new or alternative therapies for depression, although safety information for some of these treatments in pregnancy and lactation are needed. Maternal health bundles call for close attention to perinatal mental health screening with validated instruments, and for timely treatment referrals in the 'fourth trimester'.

SUMMARY

Clinical monitoring and timely treatment of depression in the perinatal and postpartum periods is critical for maternal postpartum health and recovery. Perinatal specialists and researchers should continue to focus on tailored treatments specific to this special population.

A systematic review of patient-reported outcome measures used to assess sleep in postpartum women using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines

STUDY OBJECTIVES

We performed a systematic review to identify the best patient-reported outcome measure (PROM) of postpartum sleep in women.

METHODS

We searched 4 databases for validated PROMs used to assess postpartum sleep. Studies were considered if they evaluated at least 1 psychometric measurement property of a PROM. An overall rating was assigned for each psychometric measurement property of each PROM based upon COSMIN criteria. A modified GRADE approach was used to assess the level of evidence and recommendations were then made for each PROM.

RESULTS

We identified 15 validation studies of 8 PROMs, in 9,070 postpartum women. An adequate number of sleep domains was assessed by 5 PROMs: Bergen Insomnia Scale (BIS), Pittsburgh Sleep Quality Index (PSQI), General Sleep Disturbance Scale (GSDS), Athens Insomnia Scale (AIS) and the Sleep Symptom Checklist (SSC). BIS and GSDS were the only PROMs to demonstrate adequate content validity and at least a low level of evidence of sufficient internal consistency, resulting in Class A recommendations. The BIS was the only PROM, which is easily accessible and free to use for non-commercial research, that achieved a Class A recommendation.

CONCLUSION

The BIS is the best currently available PROM of postpartum sleep. However, this PROM fails to assess several important domains such as sleep duration (and efficiency), chronotype, sleep-disordered breathing and medication usage. Future studies should focus on evaluating the psychometric measurement properties of BIS in the North American setting and in different cultural groups, or to develop a more specific PROM of postpartum sleep.

A systematic review of patient-reported outcome measures to assess postpartum pain using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines

BACKGROUND

We performed a systematic review using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines to identify the best available patient-reported outcome measure (PROM) of postpartum pain.

METHODS

This review follows COSMIN guidelines. We searched four databases with no date limiters, for previously identified validated PROMs used to assess postpartum pain. PROMs evaluating more than one author-defined domain of postpartum pain were assessed. We sought studies evaluating psychometric properties. An overall rating was then assigned based upon COSMIN analysis, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the level of evidence for psychometric properties of included PROMs. These assessments were used to make recommendations and identify the best PROM to assess postpartum pain.

RESULTS

We identified 19 studies using seven PROMs (involving 3511 women), which evaluated postpartum pain. All included studies evaluated ≥1 psychometric property of the included PROMs. An adequate number of pain domains was assessed by the Brief Pain Inventory (BPI), Short Form-BPI (SF-BPI), and McGill Pain Questionnaire (MPQ). The SF-BPI was the only PROM to demonstrate adequate content validity and at least a low-level of evidence for sufficient internal consistency, resulting in a Class A recommendation (the best performing instrument, recommended for use).

CONCLUSION

SF-BPI is the best currently available PROM to assess postpartum pain. However, it fails to assess several important domains and only just met the criteria for a Class A recommendation. Future studies are warranted to develop, evaluate, and implement a new PROM designed to specifically assess postpartum pain.

Use of Patient-Reported Outcome Measures to Assess Outpatient Postpartum Recovery: A Systematic Review

IMPORTANCE

Outpatient postpartum recovery is an underexplored area of obstetrics. There is currently no consensus regarding which patient-reported outcome measure (PROM) clinicians and researchers should use to evaluate postpartum recovery.

OBJECTIVE

To evaluate PROMs of outpatient postpartum recovery using Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines.

EVIDENCE REVIEW

An initial literature search performed in July 2019 identified postpartum recovery PROMs and validation studies. A secondary search in July 2020 identified additional validation studies. Both searches were performed using 4 databases (Web of Science, Embase, PubMed, and CINAHL), with no date limiters. Studies with PROMs evaluating more than 3 proposed outpatient postpartum recovery domains were considered. Studies were included if they assessed any psychometric measurement property of the included PROMs in the outpatient postpartum setting. The PROMs were assessed for the following 8 psychometric measurement properties, as defined by COSMIN: content validity, structural validity, internal consistency, cross-cultural validity and measurement invariance, reliability, measurement error, hypothesis testing, and responsiveness. Psychometric measurement properties were evaluated in each included study using the COSMIN criteria by assessing (1) the quality of the methods (very good, adequate, doubtful, inadequate, or not assessed); (2) overall rating of results (sufficient, insufficient, inconsistent, or indeterminate); (3) level of evidence assessed using the Grading of Recommendations, Assessment, Development and Evaluations assessment tool; and (4) level of recommendation, which included class A (recommended for use; showed adequate content validity with at least low-quality evidence for sufficient internal consistency), class B (not class A or class C), or class C (not recommended).

FINDINGS

In total, 15 PROMs (7 obstetric specific and 8 non-obstetric specific) were identified, evaluating outpatient postpartum recovery in 46 studies involving 19 165 women. The majority of psychometric measurement properties of the included PROMs were graded as having very-low-level or low-level evidence. The best-performing PROMs that received class A recommendations were the Maternal Concerns Questionnaire, the Postpartum Quality of Life tool, and the World Health Organization Quality of Life-BREF. The remainder of the evaluated PROMs had insufficient evidence to make recommendations regarding their use (and received class B recommendations).

CONCLUSIONS AND RELEVANCE

This review found that the best-performing PROMs currently available to evaluate outpatient postpartum recovery were the Maternal Concerns Questionnaire, the Postpartum Quality of Life tool, and the World Health Organization Quality of Life-BREF; however, these tools all had significant limitations. This study highlights the need to focus future efforts on robustly developing and validating a new PROM that may comprehensively evaluate outpatient postpartum recovery.

Postpartum recovery: what does it take to get back to a baseline?

PURPOSE OF REVIEW

Limited guidance exists regarding how to assess postpartum recovery. In this article, we discuss various aspects of inpatient and outpatient postpartum recovery.

RECENT FINDINGS

The postpartum period for many women includes sleep deprivation, maternal-neonatal bonding, breastfeeding, and integrating a new life into the family unit. Factors which impact inpatient quality of recovery include pain, nausea or vomiting, dizziness, shivering, comfort, mobilization, ability to hold and feed the baby, personal hygiene maintenance, and feeling in control. Outpatient recovery domains include psychosocial distress, surgical/medical factors, feeding and breast health, psychosocial support, pain, physical function, sleep, motherhood experience, infant health, fatigue, appearance / cosmetic factors, sexual function, and cognition. Postpartum recovery is likely to take longer than six weeks; however, no consensus regarding recovery duration exists among professional societies. Obstetric quality of recovery (ObsQoR) is a recommended measure of inpatient postpartum recovery; however, studies are needed to determine the optimum outpatient recovery assessment tool.

SUMMARY

Postpartum recovery is an important area that requires clinical and research attention. Future studies should focus on identifying and developing valid, reliable, and responsive measures of recovery as well as tracking and optimizing recovery domains following all delivery modes.
