BackgroundIn the mid-2000s, neonatal mortality accounted for almost 40% of deaths of children under 5 years worldwide, and constituted 65% of infant deaths in India. The neonatal mortality rate in Andhra Pradesh was 44 per 1,000 live births, and was higher in the rural areas and tribal regions, such as the Nagarkurnool division of Mahabubnagar district (which became Nagarkurnool district in Telangana in 2014). The aim of the CHAMPION trial was to investigate whether a package of interventions comprising community health promotion and provision of health services (including outreach and facility-based care) could lead to a reduction of the order of 25% in neonatal mortality.Methods and findingsThe design was a trial in which villages (clusters) in Nagarkurnool with a population < 2,500 were randomised to the CHAMPION package of health interventions or to the control arm (in which children aged 6–9 years were provided with educational interventions—the STRIPES trial). A woman was eligible for the CHAMPION package if she was married and <50 years old, neither she nor her husband had had a family planning operation, and she resided in a trial village at the time of a baseline survey before randomisation or married into the village after randomisation. The CHAMPION intervention package comprised community health promotion (including health education via village health worker–led participatory discussion groups) and provision of health services (including outreach, with mobile teams providing antenatal check-ups, and facility-based care, with subsidised access to non-public health centres [NPHCs]). Villages were stratified by travel time to the nearest NPHC and tribal status, and randomised (1:1) within strata. The primary outcome was neonatal mortality. Secondary outcomes included maternal mortality, causes of death, health knowledge, health practices including health service usage, satisfaction with care, and costs. The baseline survey (enumeration) was carried out between August and November 2007. After randomisation on 18 February 2008, participants, data collectors, and data analysts were not masked to allocation. The intervention was initiated on 1 August 2008. After an inception period, the assessment start date was 1 December 2008. The intervention ended on 31 May 2011, and data collection was completed on 30 November 2011. Primary analyses followed the intention to treat principle. In all, 14,137 women were enrolled in 232 control villages, and 15,532 in 232 intervention villages. Of these, 4,885 control women had 5,474 eligible pregnancies and gave birth to 4,998 eligible children. The corresponding numbers in intervention villages were 5,664 women, 6,351 pregnancies, and 5,798 children. Of the live-born babies, 343 (6.9%) in the control arm and 303 (5.2%) in the intervention arm died in their first 28 days of life (risk ratio 0.76, 95% CI 0.64 to 0.90, p = 0.0018; risk difference −1.59%, 95% CI −2.63% to −0.54%), suggesting that there were 92 fewer deaths (95% CI 31 to 152) as a result of the intervention. There were 9 (0.16%) maternal deaths in the control arm compared to 13 (0.20%) in the intervention arm (risk ratio 1.24, 95% CI 0.53 to 2.90, p = 0.6176; 1 death was reported as a serious adverse event). There was evidence of improved health knowledge and health practices including health service usage in the intervention arm compared to the control arm. Women in the intervention arm were more likely to rate their delivery and postnatal care as good or very good. The total cost of the CHAMPION interventions was US$1,084,955 ($11,769 per life saved, 95% CI $7,115 to $34,653). The main limitations of the study included that it could not be masked post-randomisation and that fetal losses were not divided into stillbirths and miscarriages because gestational age was not reliably reported.ConclusionsThe CHAMPION trial showed that a package of interventions addressing health knowledge and health seeking behaviour, buttressing existing health services, and contracting out important areas of maternal and child healthcare led to a reduction in neonatal mortality of almost the hypothesized 25% in small villages in an Indian state with high mortality rates. The intervention can be strongly justified in much of rural India, and is of potential use in other similar settings. Ongoing changes in maternal and child health programmes make it imperative that a similar intervention that establishes ties between the community and health facilities is tested in different settings.Trial registrationISRCTN registry ISRCTN24104646
