Research priorities in Maternal, Newborn, & Child Health & Nutrition for India: An Indian Council of Medical Research-INCLEN Initiative

Research priorities for care of preterm or low birth weight infants: health policy

Research priorities for preterm or low birth weight (LBW) infants were advanced in 2012, and other research priority-setting exercises since then have included more limited, context-specific research priorities pertaining to preterm infants. While developing new World Health Organization (WHO) guidelines for care of preterm or LBW infants, we conducted a complementary research prioritisation exercise. A diverse, globally representative guideline development group (GDG) of experts - all authors of this paper along with WHO steering group for preterm-LBW guidelines - was assembled by the WHO to examine evidence and consider a variety of factors in intervention effectiveness and implementation, leading to 25 new recommendations and one good practice statement for care of preterm or LBW infants. The GDG generated research questions (RQs) based on contributions to improvements in care and outcomes of preterm or LBW infants, public health impacts, answerability, knowledge gaps, feasibility of implementation, and promotion of equity, and then ranked the RQs based on their likelihood to further change or influence the WHO guidelines for the care of preterm or LBW infants in the future. Thirty-six priority RQs were identified, 32 (89%) of which focused on aspects of intervention effectiveness, and the remaining four addressed implementation ("how") questions. Of the top 12 RQs, seven focused on further advancing new recommendations - such as family involvement and support in caring for preterm or LBW infants, emollient therapy, probiotics, immediate KMC for critically ill newborns, and home visits for post-discharge follow-up of preterm or LBW infants - and three RQs addressed issues of feeding (breastmilk promotion, milk banks, individualized feeding). RQs prioritised here will be critical for optimising the effectiveness and delivery of new WHO recommendations for care of preterm or LBW infants. The RQs encompass unanswered research priorities for preterm or LBW infants from prior prioritisation exercises which were conducted using Child Health and Nutrition Research Initiative (CHNRI) methodology.

Coverage of antenatal iron-folic acid and calcium distribution during pregnancy and their contextual determinants in the northeastern region of India

Iron-folic acid (IFA) and calcium supplementation are nutritional interventions recommended prophylactically (against maternal anemia and preeclampsia, respectively) to all antenatal mothers in India under basic antenatal care (ANC) services. Using Health Management Information System data (reporting period: 2018–19 to 2020–21), we mapped the coverage of antenatal IFA and calcium distribution across the remote northeastern region of India relative to the number of pregnant women (PW) who registered for ANC, disaggregated by states and districts. Variations in coverage were also investigated by subgroups based on contextual attributes, viz., physiography (hilly/ plateau/ plain), socioeconomic development (“aspirational”/ “non-aspirational”) and proportion of early ANC visits (low/ medium/ high). Full course of antenatal IFA and calcium supplements were received by 79.36 (95% CI: 79.31–79.40) and 61.26 (95% CI: 61.21–61.32) PW per 100 ANC registered women, respectively. There was widespread heterogeneity in outreach, with calcium coverage generally trailing behind IFA coverage. Among states, coverage of the two interventions (per 100 ANC registered women) was highest in Assam (97.06 and 78.11 PW, respectively) and lowest in Nagaland (24.87 and 16.77 PW, respectively). At the district-level, the two interventions failed to reach even 50 PW per 100 ANC registered women in 32 (out of 115) districts. The coverage tended to be inferior in districts that were hilly, “non-aspirational” and had low proportion of early ANC visits. The granular information provided by our findings will facilitate monitoring, root cause analyses, microplanning, informed resource allocation and tailoring of locally appropriate solutions to achieve targeted coverage improvements.

Vitamin A supplementation among 9-59 month old children in India: geospatial perspectives and implications for targeted coverage

Introduction

Vitamin A supplementation (VAS) is yet to reach all Indian children aged 9–59 months, despite guidelines for universal coverage. This study mapped geospatial patterns underlying VAS coverage across two policy-relevant administrative unit levels (states and districts) in India. The relationship between spatial distribution of VAS coverage and vitamin A deficiency (VAD) prevalence was also investigated.

Methods

The study draws on nationally representative cross-sectional data collected during National Family and Health Survey 4 (NFHS-4) and Comprehensive National Nutritional Survey (CNNS). VAS coverage was estimated using information obtained during NFHS-4 from mothers about whether their children (n=204 645) had received VAS within 6 months of the survey. VAD prevalence estimates were based on serum retinol measurements during CNNS in under-five children (n=9563). State-level and district-level choropleth maps of VAS coverage were constructed. Spatial patterns were probed using Moran’s statistics, scatter plots and local indicators of spatial association (LISA). Relationship between VAS coverage (as an explanatory variable) and VAD prevalence was explored using spatial autoregressive models.

Results

VAS coverage in India (overall 60.5%) ranged from 29.5% (Nagaland) to 89.5% (Goa) across the various states/union territories. Among districts, it ranged from 12.8% (Longleng district, Nagaland) to 94.5% (Kolar district, Karnataka). The coverage exhibited positive spatial autocorrelation, more prominently at the district-level (univariate Moran’s I=0.638, z-value=25.614, pseudo p value=0.001). LISA maps identified spatial clusters of high coverage and low coverage districts. No significant spatial association was observed between VAS coverage and VAD prevalence in the states during spatial error (R²=0.07, λ=0.30, p value=0.14) and spatial lag (R²=0.05, ρ=0.25, p value=0.23) regression.

Conclusion

Two out of every five eligible Indian children were not supplemented with vitamin A. The coverage was geographically heterogeneous with discernible spatial patterns. Their consequences on vitamin A status and associated health effects in the community deserve close monitoring.

Shifting research priorities in maternal and child health in the COVID-19 pandemic era in India: A renewed focus on systems strengthening

BACKGROUND

The remarkable progress seen in maternal and child health (MCH) in India over the past two decades has been impacted by the COVID-19 pandemic. We aimed to undertake a rapid assessment to identify key priorities for public health research in MCH in India within the context and aftermath of the COVID-19 pandemic.

METHODS

A web-based survey was developed to identify top research priorities in MCH. It consisted of 26 questions on six broad domains: vaccine preventable diseases, outbreak preparedness, primary healthcare integration, maternal health, neonatal health, and infectious diseases. Key stakeholders were invited to participate between September and November 2020. Participants assigned importance on a 5-point Likert scale, and assigned overall ranks to each sub-domain research priority. Descriptive statistics were used to examine Likert scale responses, and a ranking analysis was done to obtain an "average ranking score" and identify the top research priority under each domain.

RESULTS

Amongst the 84 respondents from across 15 Indian states, 37% were public-health researchers, 25% healthcare providers, 20% academic faculty and 13% were policy makers. Most respondents considered conducting systems strengthening research as extremely important. The highest ranked research priorities were strengthening the public sector workforce (vaccine preventable diseases), enhancing public-health surveillance networks (outbreak preparedness), nutrition support through community workers (primary care integration), encouraging at least 4-8 antenatal visits (maternal health), neonatal resuscitation to reduce birth asphyxia (neonatal health) and screening and treatment of tuberculosis (infectious diseases). Common themes identified through open-ended questions primarily included systems strengthening priorities across domains.

CONCLUSIONS

The overall focus for research priorities in MCH in India during the COVID-19 pandemic is on strengthening existing services and service delivery, rather than novel research. Our results highlight pivotal steps within the roadmap for advancing and sustaining maternal and child health gains during the ongoing COVID-19 pandemic and beyond.

Knowledge, attitude and practices on developmental surveillance and screening among health professionals in Indian health care settings: An exploratory sequential mixed methods study

PURPOSE

The purpose of this study was to assess the knowledge, attitude and practices of health care professionals in pediatric settings on developmental surveillance and screening programs and also to identify the barriers and facilitators during its implementation.

METHODS

The data were collected from health professionals involved in pediatric developmental care, practicing in various hospitals, clinics and nursing homes in a suburban city on west coast of Southern India. The study involved cross-sectional exploratory sequential mixed method design which included a quantitative questionnaire survey on health professionals (n= 52) followed by qualitative face-to-face interviews with chosen respondents who participated in the survey (n= 8). The survey data are reported with descriptive statistics, and interview data are subjected to inductive content analysis for deriving codes, categories and themes.

RESULTS

The study results indicate that health professionals involved in pediatric developmental care in Indian health care settings have fair knowledge and a favorable attitude towards the use of developmental surveillance and screening. Furthermore, the facilitators and barriers of implementation have been reported. The strategies outlined by interview respondents to improve adherence to implementation have been discussed.

CONCLUSIONS

The practice of developmental surveillance and screening is limited despite favorable knowledge and attitude among health professionals in pediatric developmental care and is dependent on health care organizational setup.

Setting priorities in child health research in India for 2016-2025: a CHNRI exercise undertaken by the Indian Council for Medical Research and INCLEN Trust

Background

Millennium Development Goal 4 (MDGs) mobilised countries to reduce child mortality by two thirds the 1990 rate in 2015. While India did not reach MDG 4, it considerably reduced child mortality in the MDG-era. Efficient and targeted interventions and adequate monitoring are necessary to further progress in improvements to child health. Looking forward to the Sustainable Development Goal (SDG)-era, the Indian Council of Medical Research and The INCLEN Trust International conducted a national research priority setting exercise for maternal, child, newborn health, and maternal and child nutrition. Here, results are reported for child health.

Methods

The Child Health and Nutrition Research Initiative (CHNRI) method for research priority setting was employed. Research ideas were crowd-sourced from a network of child health experts from across India; these were refined and consolidated into research options (ROs) which were scored against five weighted criteria to arrive weighted Research Priority Scores (wRPS). National and regional priority lists were prepared.

Results

90 experts contributed 596 ideas that were consolidated into 101 research options (ROs). These were scored by 233 experts nationwide. National wRPS for ROs ranged between 0.92 and 0.51. The majority of the top research priorities related to development of cost-effective interventions and their implementation, and impact evaluations, improving data quality; and monitoring of existing programs, or improving the management of morbidities. The research priorities varied between regions, the Economic Action Group and North-Eastern states prioritised questions relating to delivering interventions at community- or household-level, whereas the North-Eastern states and Union Territories prioritised research questions involving managing and measuring malaria, and the Southern and Western states prioritised research questions involving pharmacovigilance of vaccines, impact of newly introduced vaccines, and delivery of vaccines to hard-to-reach populations.

Conclusions

Research priorities varied geographically, according the stage of development of the area and mostly pertained to implementation sciences, which was expected given diversity in epidemiological profiles. Priority setting should help guide investment decisions by national and international agencies, therefore encouraging researchers to focus on priority areas. The ICMR has launched a grants programme for implementation research on maternal and child health to pursue research priorities identified by this exercise.

Goat lung surfactant for treatment of respiratory distress syndrome among preterm neonates: a multi-site randomized non-inferiority trial

OBJECTIVE

To investigate the safety and efficacy of goat lung surfactant extract (GLSE) compared with bovine surfactant extract (beractant; Survanta®, AbbVie, USA) for the treatment of neonatal respiratory distress syndrome (RDS).

STUDY DESIGN

We conducted a double-blind, non-inferiority, randomized trial in seven Indian centers between June 22, 2016 and January 11, 2018. Preterm neonates of 26 to 32 weeks gestation with clinical diagnosis of RDS were randomized to receive either GLSE or beractant. Repeat dose, if required, was open-label beractant in both the groups. The primary outcome was a composite of death or bronchopulmonary dysplasia (BPD) at 36 weeks postmenstrual age (PMA). Interim analyses were done by an independent data and safety monitoring board (DSMB).

RESULT

After the first interim analyses on 5% enrolment, the "need for repeat dose(s) of surfactant" was added as an additional primary outcome and enrolment restricted to intramural births at five of the seven participating centers. Following second interim analysis after 98 (10% of 900 planned) neonates were enroled, DSMB recommended closure of study in view of inferior efficacy of GLSE in comparison to beractant. There was no significant difference in the primary outcome of death or BPD between GLSE group (n = 52) and beractant group (n = 46) (50.0 vs. 39.1%; OR 1.5; 95% CI 0.7-3.5; p = 0.28). The need for repeat dose of surfactant was significantly higher in GLSE group (65.4 vs. 17.4%; OR 9.0; 95% CI 3.5-23.3; p < 0.001).

CONCLUSIONS

Goat lung surfactant was less efficacious than beractant (Survanta®) for treatment of RDS in preterm infants. Reasons to ascertain inferior efficacy of goat lung surfactant requires investigation and possible mitigating strategies in order to develop a low-cost and effective surfactant.
