Selected AbstractsNavigating toward Fetal and Maternal Health: The Challenge of Treating Epilepsy in PregnancyEPILEPSIA, Issue 10 2004Torbjörn Tomson Summary:, A rational approach to the treatment of women of childbearing potential with epilepsy has been hampered by the lack of conclusive data on the comparative teratogenic potential of different antiepileptic drugs (AEDs). Although, several cohort studies on birth defects associated with AED use during pregnancy have been published, these have generally failed to demonstrate differences in malformation rates between AEDs, probably mainly due to insufficient power. In particular, pregnancies with new generation AEDs have been too few. In recent years, pregnancy registries have been introduced to overcome this problem,EURAP (an international collaboration), the North American, and the U.K. AED and pregnancy registries are observational studies that prospectively assess pregnancy outcome after AED exposure using slightly different methods. Each has enlisted 3,5,000 pregnancies in women with epilepsy, and the North American and the U.K. have released preliminary observations. Thus the U.K. registry reported a higher malformation rate with valproate, 5.9% (4.3,8.2%; 95% CI), than with carbamazepine, 2.3% (1.4,3.7%), and lamotrigine, 2.1% (1.0,4.0%). Most of the more recent cohort studies have also identified a nonsignificant trend toward a higher teratogenicity with valproate. These signals need to be interpreted with some caution since none of the studies to date have fully assessed the impact of possible confounders, such as type of epilepsy, family history of birth defects, etc. However, with increasing number of pregnancies it should be possible in the near future for the pregnancy registries to take such confounding factors into account and thus make more reliable assessments of the causal relationship between exposure to specific AEDs and teratogenic risks. While awaiting more conclusive results, it appears reasonable to be cautious in prescribing valproate to women considering to become pregnant if other suitable treatment alternatives, and with less teratogenic potential, are available. Any attempt to change treatment should, however, be accomplished well before conception. The importance of maintained seizure control must also be kept in mind, and the woman who needs valproate to control her seizures should not be discouraged from pregnancy, provided that counseling at the best of available knowledge is given.

We argue that a key beneficiary , the mother , has been left completely out of the analysis. If prenatal care significantly improves the health of the mother, then concluding that prenatal care is ,ineffective' or that the Medicaid expansions are a ,failure' is premature. This paper seeks to rectify the oversight by estimating the impact of prenatal care on maternal health and the associated cost savings. We first set up a joint maternal,infant health production framework that informs our empirical analysis. Using data from the National Maternal and Infant Health Survey, we estimate the effects of prenatal care on several different measures of maternal health such as body weight status and excessive hospitalizations. Our results suggest that receiving timely and adequate prenatal care may increase the probability of maintaining a healthy weight after the birth and, perhaps for blacks, of avoiding a lengthy hospitalization after the delivery. Given the costs to society of obesity and hospitalization, these are benefits worth exploring before making conclusions about the effectiveness of prenatal care , and Medicaid.

[source] A register study of the impact of stopping third trimester selective serotonin reuptake inhibitor exposure on neonatal healthACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2010W. Warburton Warburton W, Hertzman C, Oberlander TF. A register study of the impact of stopping third trimester selective serotonin reuptake inhibitor exposure on neonatal health. Objective:, To determine whether risk for adverse neonatal outcomes are reduced by stopping SSRI use before the end of pregnancy. Method:, Using population health data, maternal health and prenatal SSRI prescriptions were linked to neonatal birth records (N = 119 547) (1998,2001). Neonates SSRI-exposed in the last 14 days (L14) of gestation were compared with infants who had gestational exposure, but not during the last 14 days (NL14). Propensity score matching was used to control for potential confounders (total exposure, maternal health characteristics). Results:, Increased risk for neonatal respiratory distress was present where L14 exposure occurred compared with risk where exposure stopped before L14. However, controlling for potential maternal and neonatal confounders, differences disappeared. Conclusion:, Controlling for maternal illness severity, reducing exposure to SSRI's at the end of pregnancy had no significant clinical effect on improving neonatal health. These findings raise the possibility that some adverse neonatal outcomes may not be an acute pharmacological condition such as toxicity or withdrawal.

[source] Role of a fetal defence mechanism against oxidative stress in the aetiology of preeclampsiaHISTOPATHOLOGY, Issue 1 2009Christoph Jan Wruck Aims:, Increasing evidence suggests that oxidative stress may play a key role in the aetiology of preeclampsia (PE). The aim of this study was to elucidate the placental defence mechanisms employed against oxidative stress and, in particular, the specific role of nuclear factor erythroid 2-related factor 2 (Nrf2). Methods and results:, Expression of Nrf2 in third-trimester placental tissue was compared in preeclamptic and normal gestation-matched controls. PE was associated with increased Nrf2 activity within cytotrophoblastic nuclei. Nrf2 expression was restricted to proliferative and early post-proliferative cytotrophoblast only. Syncytiotrophoblast was immunonegative for Nrf2 in both controls and preeclamptic placentas. Conclusions:, Nrf2 is exclusively active within cytotrophoblast, strongly suggesting that these cells are the origin of Nrf2-dependent gene products. Syncytiotrophoblast is transcriptionally inactive; therefore in times of oxidative stress essential cytoprotective enzymes must be derived from the cytotrophoblast. Excessive cytotrophoblastic turnover causes disproportionate release of toxic placental factors, manifesting as PE and endangering maternal health. Increased cytotrophoblastic proliferation/fusion could thus be interpreted as a fetal defence mechanism, initiated in response to the requirements of vulnerable syncytiotrophoblast. We therefore propose a direct relationship between fetal defence against oxidative stress and consequent placental toxicity as part of the aetiology of this complex maternal disease. [source] Costs of maternal health care services in three anglophone African countriesINTERNATIONAL JOURNAL OF HEALTH PLANNING AND MANAGEMENT, Issue 1 2003Ann Levin Abstract This paper is a synthesis of a case study of provider and consumer costs, along with selected quality indicators, for six maternal health services provided at one public hospital, one mission hospital, one public health centre and one mission centre, in Uganda, Malawi and Ghana. The study examines the costs of providing the services in a selected number of facilities in order to examine the reasons behind cost differences, assess the efficiency of service delivery, and determine whether management improvements might achieve cost savings without hurting quality. This assessment is important to African countries with ambitious goals for improving maternal health but scarce public health resources and limited government budgets. The study also evaluates the costs that consumers pay to use the maternal health services, along with the contribution that revenues from fees for services make to recovering health facility costs. The authors find that costs differ between hospitals and health centres as well as among mission and public facilities in the study sample. The variation is explained by differences in the role of the facility, use and availability of materials and equipment, number and level of personnel delivering services, and utilization levels of services. The report concludes with several policy implications for improvements in efficiency, financing options and consumer costs. Copyright © 2003 John Wiley & Sons, Ltd. [source] Is there an association between periodontal disease, prematurity and low birth weight?JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 9 2005A population-based study Abstract Background: The relationship between periodontal diseases in pregnancy and children born prematurely or with low birth weight has been increasingly investigated, showing inconclusive results. Objectives: To test the link between periodontal disease in pregnant women and low birth weight or prematurity. Methods: A population-based, cross-sectional study was carried out in Southern Brazil. The sample consisted of 449 parturients who were interviewed and examined up to 48 h post-partum. Three outcomes were investigated: low birth weight, prematurity and prematurity and/or birth weight. Periodontal disease, the exposure, was defined as (i) at least one site with a periodontal pocket; (ii) the presence of pockets at four or more sites. Socio-demographic information relating to health and maternal habits was collected through a questionnaire and by hospital medical records. Simple and multiple regression analysis was performed. Findings: There was no statistically significant association between periodontal disease and low birth weight. Periodontal pocket was not associated with low birth weight and/or pre-term birth after being adjusted. A periodontal pocket in at least one site was associated with prematurity (odds ratio=2.6; 95% confidence interval 1.0,6.9) even after adjusting for maternal schooling, parity, number of previous children of low birth weight, number of pre-natal consultations and body mass index. After the introduction of variables relating to maternal health during pregnancy, this association disappeared. Conclusions: No association was found between periodontal disease in the mother and the low birth weight. An association between prematurity and periodontal pockets was found but it was confounded by maternal health variables. [source] Incorporating nutrition into delivery care: delivery care practices that affect child nutrition and maternal healthMATERNAL & CHILD NUTRITION, Issue 4 2009Camila M. Chaparro Abstract Delayed umbilical cord clamping, early skin-to-skin contact and early initiation of exclusive breastfeeding are three simple and inexpensive delivery care practices which have the potential to improve short-term and long-term nutrition and health outcomes in mothers and infants. In preterm infants, delayed clamping prevents intraventricular haemorrhage and improves haematological status, and in full-term infants, delayed clamping improves iron status through 6 months of age. Early skin-to-skin contact, in addition to regulating neonatal temperature, improves early breastfeeding behaviours, which has important implications for long-term infant nutrition and health. Finally, early exclusive breastfeeding prevents neonatal mortality and morbidity and provides numerous health and nutritional benefits to the infant, throughout infancy and beyond, as well as to the mother. Though each practice has been the subject of controlled trials and systematic reviews, with evidence of benefit from their implementation, these practices are not common in many delivery settings, nor are their long-term effects on infant and maternal nutrition and health status adequately recognized. We discuss the immediate and long-term health and nutrition benefits of each practice, and identify the policy and programme changes needed for integration and implementation of these practices into standard delivery care. [source] Specific IgE to allergens in cord blood is associated with maternal immunity to Toxoplasma gondii and rubella virusALLERGY, Issue 11 2008M. J. Ege Background:, Various studies have found reduced prevalences of atopic sensitization and atopic diseases in children previously exposed to infections or living conditions with a high microbial burden, such as the farming environment. Objective:, We sought to determine the relationships of cord blood immunoglobulin E (IgE) with maternal health conditions before and during pregnancy. Methods:, Pregnant women living in rural areas in five European countries were recruited in the third trimester of pregnancy. Information on maternal health during pregnancy was collected from maternity records and by questionnaires (n = 497). Specific IgE for inhalant and food allergens was assessed in cord blood and peripheral blood samples of the mothers. Results:, Inverse associations of cord blood IgE to seasonal allergens with positive maternal records for Toxoplasma gondii (adjusted odds ratio = 0.37 [0.17,0.81]) and rubella virus (adjusted odds ratio = 0.35 [0.13,0.96]) were found. The previously described effect of prenatal farm exposure on IgE to seasonal allergens was partly confounded by a positive maternal record for T. gondii. The number of maternal siblings, maternal contact to cats during pregnancy or during her first year of life, predicted a positive maternal record for T. gondii. Conclusions:, Maternal immunity to T. gondii and rubella may impact on atopic sensitization in the fetus. A positive T. gondii record explained the previously identified effect of prenatal farm exposure on IgE to seasonal allergens only to a minor extent. [source] United States vital statistics and the measurement of gestational agePAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 2007Joyce A. Martin Summary Estimates of the gestational age of the newborn based on US Birth Certificate data are extensively used to monitor trends in infant and maternal health and to improve our understanding of adverse pregnancy outcome. Two measures of gestational age, the ,date of the last normal menses' (LMP) and the ,clinical estimate of gestation' (CE), have been available from birth certificate data since 1989. Reporting irregularities with the LMP-based measure are well-documented, and important questions remain regarding the derivation of the CE. Changes in perinatal medicine and in vital statistics reporting in recent years may have importantly altered gestational age data based on vital statistics. This study describes how gestational age measures are collected and edited in US national vital statistics, and examines changes in the reporting of these measures by race and Hispanic origin between 1990 and 2002. Data are drawn from the National Center for Health Statistics' restricted use US birth files for 1990,2002. Bivariable statistics are used. The percentage of records with missing LMP dates declined markedly over the study period, overall, and for each racial/Hispanic origin group studied. A marked shift in the distribution of the CE of gestational age was also observed, suggesting changes both in the true distribution of age at birth, and in the derivation of this measure. Agreement between the LMP-based and CE estimates increased over the study period, especially among preterm births. However, a high proportion of LMP dates continue to be missing or invalid and the derivation of the CE is still uncertain. In sum, although the reporting of gestational age measures in vital statistics appears to have improved between 1990 and 2002, substantial concerns with both the LMP-based and the CE persist. Efforts to identify approaches to further improve upon the quality of these data are needed. [source] How effective is antenatal care in preventing maternal mortality and serious morbidity?PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 2001An overview of the evidence This is an overview of evidence of the effectiveness of antenatal care in relation to maternal mortality and serious morbidity, focused in particular on developing countries. It concentrates on the major causes of maternal mortality, and traces their antecedent morbidities and risk factors in pregnancy. It also includes interventions aimed at preventing, detecting or treating any stage along this pathway during pregnancy. This is an updated and expanded version of a review first published by the World Health Organization (WHO) in 1992. The scientific evidence from randomised controlled trials and other types of intervention or observational study on the effectiveness of these interventions is reviewed critically. The sources and quality of available data, and possible biases in their collection or interpretation are considered. As in other areas of maternal health, good-quality evidence is scarce and, just as in many aspects of health care generally, there are interventions in current practice that have not been subjected to rigorous evaluation. A table of antenatal interventions of proven effectiveness in conditions that can lead to maternal mortality or serious morbidity is presented. Interventions for which there is some promising evidence, short of proof, of effectiveness are explored, and the outstanding questions formulated. These are presented in a series of tables with suggestions about the types of study needed to answer them. [source] Maternal height and child mortality in 42 developing countriesAMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 3 2009Christiaan W. S. Monden Previous research reports mixed results about the association between maternal height and child mortality. Some studies suggest that the negative association might be stronger in contexts with fewer resources. This hypothesis has yet not been tested in a cross-nationally comparative design. We use data on 307,223 children born to 194,835 women in 444 districts of 42 developing countries to estimate the association between maternal height and child mortality and test whether this association is modified by indicators at the level of the household (like sex, age and twin status of the child and socio-economic characteristics of the mother and her partner), district (regional level of development, public health facilities and female occupational attainment) and country (GDP per capita). We find a robust negative effect of logged maternal height on child mortality. The effect of maternal health is strongest for women with least education and is more important in the first year after birth and for twin births. The indicators of development at the district and country level do not modify the effect of maternal height. Am. J. Hum. Biol. 2009. © 2008 Wiley-Liss, Inc. [source] Recurrence rates of cardiac manifestations associated with neonatal lupus and maternal/fetal risk factorsARTHRITIS & RHEUMATISM, Issue 10 2009Carolina Llanos Objective Identifying the frequency of recurrent cardiac manifestations of neonatal lupus (NL) in a second child is critical to understanding the pathogenesis of anti-SSA/Ro,mediated injury and would improve counseling strategies regarding future pregnancies and power the design of clinical prevention trials. Accordingly, this study was undertaken to address the recurrence rates of cardiac NL and associated risk factors in a large US-based cohort. Methods Families enrolled in the Research Registry for Neonatal Lupus were evaluated for rates of recurrence of cardiac NL and potential risk factors, with a focus on pregnancies immediately following the birth of an affected child. Results The overall rate of recurrence of cardiac NL in 161 pregnancies of 129 mothers with anti-SSA/Ro antibodies was 17.4% (95% confidence interval 11.1,23.6%). Analysis of the potential risk factors among 129 mothers with a pregnancy immediately following the birth of a child with cardiac NL showed that the maternal diagnosis was not associated with the outcome in a subsequent pregnancy. In this group, 23% of mothers who were either asymptomatic or had an undifferentiated autoimmune syndrome, compared with 14% of mothers with systemic lupus erythematosus or Sjögren's syndrome, had a second child with cardiac NL (P = 0.25). The recurrence rate was not statistically significantly different in mothers who had taken steroids compared with those who had not taken steroids (16% versus 21%; P = 0.78). The antibody status of the mother was not predictive of outcome in subsequent pregnancies. Moreover, death of the first child with cardiac NL was not predictive of recurrence of cardiac NL in a subsequent pregnancy (P = 0.31). The risk of cardiac NL was similar between male and female children (17.2% versus 18.3%; P = 1.0). Conclusion In this cohort, the overall recurrence rate for cardiac NL was 17%. The recurrence rate appeared to be unaffected by maternal health, use of steroids, antibody status, severity of cardiac disease in the first affected child, or sex of the subsequent child. [source] Making pregnancy safer in Australia: The importance of maternal death reviewAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 2 2008Sue KILDEA Australia is one of the safest countries in the world to birth. Because maternal deaths are rare, often the focus during pregnancy is on the well-being of the fetus. The relative safety of birth has fostered a shift in the focus of maternal health, from survival, to the model of care or the birth experience. Yet women still die in Australia as a result of child bearing and many of these deaths are associated with avoidable factors. The purpose of this paper is to outline the maternal death monitoring and review process in Australia and to present to clinicians the salient features of the most recently published Australian maternal death report. The notion of preventability and the potential for practice to have an effect on reducing maternal mortality are also discussed. [source] The health of children in sole-parent families in New Zealand: results of a population-based cross-sectional surveyAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 3 2010Martin Tobias Abstract Objective: To investigate whether children in sole-parent families in New Zealand bear excess risks of poor mental and physical health relative to children in two parent families. Data sources and statistical methods: The data source was the 2006/07 New Zealand Health Survey, a nationally representative household survey that sampled 502 children (5-14 years) of sole mothers and 1,281 children of partnered mothers. Results: Children of sole mothers were 1.26 (0.94 , 2.69) times as likely as children of partnered mothers to return a low PhS score. Adjusting for maternal health and family socio-economic disadvantage eliminated this weak association (which in any case was of borderline statistical significance). Children of sole mothers were more than twice as likely as children of partnered mothers to return a low PsS score, adjusting for demographic variables only. Conclusions: There is only a weak negative association (if any) between sole-parenting and child physical health, but a stronger association with child mental health , consistent with most of the New Zealand and international literature. The association with child mental health is largely (but possibly not completely) ,explained' by the poorer mental health of sole-parents and the poorer socio-economic circumstances of single-parent families (on average). Implications: These findings support policies aiming to improve access of sole-parents and their children to community mental health services, and (more especially) policies aiming to ameliorate the disadvantaged economic circumstances of single parent families.

First, we discuss the principles underpinning community recruitment methods in PRISM that guided both our initial approaches to, and our continuing relationships with, communities. Second, we outline the strategies used to recruit communities and to establish the groundwork for ongoing partnerships over the projected six years of the study. [source] Mothers without Companionship During Childbirth: An Analysis within the Millennium Cohort StudyBIRTH, Issue 4 2008Holly N. Essex MSc ABSTRACT: Background: Studies have highlighted the benefits of social support during labor but no studies focused on women who choose to be unaccompanied or who have no companion available at birth. Our goals were, first, to identify characteristics of women who are unaccompanied at birth and compare these to those who had support and, second, to establish whether or not being unaccompanied at birth is a risk marker for adverse maternal and infant health outcomes. Methods: The sample comprised 16,610 natural mother-infant pairs, excluding women with planned cesarean sections in the Millennium Cohort Study. Multivariable regression models were used to examine, first, sociodemographic, cultural, socioeconomic, and pregnancy characteristics in relation to being unaccompanied and, second, being unaccompanied at birth in relation to labor and delivery outcomes, maternal health and health-related behaviors, parenting, and infant health and development. Results: Mothers who were single (vs not single), multiparous (vs primiparous), of black or Pakistani ethnicity (vs white), from poor households (vs nonpoor), with low levels of education (vs high levels), and who did not attend antenatal classes (vs attenders) were at significantly higher risk of being unaccompanied at birth. Mothers unaccompanied at birth were more likely to have a preterm birth (vs term), an emergency cesarean section (vs spontaneous vaginal delivery) and spinal pain relief or a general anesthetic (vs no pain relief), a shorter labor, and lower satisfaction with life (vs high satisfaction) at 9 months postpartum. Their infants had significantly lower birthweight and were at higher risk of delayed gross motor development (vs normal development). Conclusions: Being unaccompanied at birth may be a useful marker of high-risk mothers and infants in need of additional support in the postpartum period and beyond. (BIRTH 35:4 December 2008) [source] Breastfeeding promotion for infants in neonatal units: a systematic reviewCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 2 2010M. J. Renfrew Abstract Background Breastfeeding/breastmilk feeding of infants in neonatal units is vital to the preservation of short- and long-term health, but rates are very low in many neonatal units internationally. The aim of this review was to evaluate the effectiveness of clinical, public health and health promotion interventions that may promote or inhibit breastfeeding/breastmilk feeding for infants admitted to neonatal units. Methods Systematic review with narrative synthesis. Studies were identified from structured searches of 19 electronic databases from inception to February 2008; hand searching of bibliographies; Advisory Group members helped identify additional sources. Inclusion criteria: controlled studies of interventions intended to increase breastfeeding/feeding with breastmilk that reported breastmilk feeding outcomes and included infants admitted to neonatal units, their mothers, families and caregivers. Data were extracted and appraised for quality using standard processes. Study selection, data extraction and quality assessment were independently checked. Study heterogeneity prevented meta-analysis. Results Forty-eight studies were identified, mainly measuring short-term outcomes of single interventions in stable infants. We report here a sub-set of 21 studies addressing interventions tested in at least one good-quality or more than one moderate-quality study. Effective interventions identified included kangaroo skin-to-skin contact, simultaneous milk expression, peer support in hospital and community, multidisciplinary staff training, and Unicef Baby Friendly accreditation of the associated maternity hospital. Conclusions Breastfeeding/breastmilk feeding is promoted by close, continuing skin-to-skin contact between mother and infant, effective breastmilk expression, peer support in hospital and community, and staff training. Evidence gaps include health outcomes and costs of intervening with less clinically stable infants, and maternal health and well-being. Effects of public health and policy interventions and the organization of neonatal services remain unclear. Infant feeding in neonatal units should be included in public health surveillance and policy development; relevant definitions are proposed. [source] Longitudinal validity and responsiveness of the Food Allergy Quality of Life Questionnaire , Parent Form in children 0,12 years following positive and negative food challengesCLINICAL & EXPERIMENTAL ALLERGY, Issue 3 2010A. DunnGalvin Summary Background There are no published studies of longitudinal health-related quality of life (HRQL) assessments of food-allergic children using a disease-specific measure. Objective This study assessed the longitudinal measurement properties of the Food Allergy Quality of Life Questionnaire , Parent Form (FAQLQ-PF) in a sample of children undergoing food challenge. Methods Parents of children 0,12 years completed the FAQLQ-PF and the Food Allergy Independent Measure (FAIM) pre-challenge and at 2 and 6 months post food challenge. In order to evaluate longitudinal validity, differences between Group A (positive challenge) and Group B (negative challenge) were expected over time. We computed correlation coefficients between change scores in the FAQLQ-PF and change scores in the FAIM. To determine the minimally important difference (MID), we used distributional criterion and effect size approaches. A logistic regression model profiled those children falling below this point. Results Eighty-two children underwent a challenge (42 positive; 40 negative). Domains and total score improved significantly at pos-challenge time-points for both groups (all P<0.05). Sensitivity was demonstrated by significant differences between positive and negative groups at 6 months [F(2, 59)=6.221, P<0.003] and by differing improvement on relevant subscales (P<0.05). MID was 0.45 on a seven-point response scale. Poorer quality of life at baseline increased the odds by over 2.0 of no improvement in HRQL scores 6-month time-point. General maternal health (OR 1.252), number of foods avoided (OR 1.369) and children >9 years (OR 1.173) were also predictors. The model correctly identified 84% of cases below MID. Conclusion The FAQLQ-PF is sensitive to change, and has excellent longitudinal reliability and validity in a food-allergic patient population. The standard error of measurement value of 0.5 points as a threshold for meaningful change in HRQL questionnaires was confirmed. The FAQLQ-PF may be used to identify problems in children, to assess the effectiveness of clinical trials or interventions, and to guide the development of regulatory policies. Cite this as: A.

[source] Pragmatic indicators for remote Aboriginal maternal and infant health care: why it matters and where to startAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2010Malinda Steenkamp Abstract Objective: There are challenges in delivering maternal and infant health (MIH) care to remote Northern Territory (NT) communities. These include fragmented care with birthing in regional hospitals resulting in cultural and geographical dislocation for Aboriginal women. Many NT initiatives are aimed at improving care. Indicators for evaluating these for remote Aboriginal mothers and infants need to be clearer. We reviewed existing indicators to inform a set of pragmatic indicators for reporting improvement in remote MIH care. Methods: Scientific databases and grey literature (organisational websites and Google Scholar) were searched using the terms ,Aboriginal/maternal/infant/remote health/monitoring performance'. Key stakeholders identified omitted indicators sets. Relevant sets were reviewed and organised by indicator type, stage of patient journey, topic and theme. Results: Forty-two indicators sets were found. Seven focused on Aboriginal health, 23 on reproductive/maternal health, eight on child/infant health and four on other aspects, e.g. remote health. We identified more than 1,000 individual indicators. Of these, 656 were relevant for our purpose and were subsequently organised into 300 topics and 16 themes for antenatal, birth and postpartum, and infant care by indicator type. Conclusion: There are many measures for monitoring health care delivery to mothers and infants. Few are framed around remote MIH services, despite poorer health outcomes of remote mothers and infants and the specific challenges with providing care in this setting. Establishing relevant indicators is vital to support relevant data collection and the development of appropriate policy for remote Aboriginal maternal and infant care. [source] |
