Integrated management of childhood illness is a globally proven primary care strategy to improve child survival and is being implemented worldwide in countries with high burden of child mortality. Its implementation as Integrated Management of Newborn and Childhood Illness (IMNCI) in India has been challenging.The primary objective of the present work was to assess the feasibility, acceptability and use of an adapted Integrated E Diagnostic Approach (IeDA) that provides e-Learning and improved clinical practices of the primary level health service provider auxiliary nurse midwives (ANMs) to deliver IMNCI services. This India-specific approach was contextualised to the Indian IMNCI programme based on 7 years of IeDA implementation learning from West Africa.The Integrated Management of Neonatal and Childhood Illness pilot was implemented across 80 front-line workers, 70 ANMs and 10 medical officers) in 55 facilities of 3 blocks of Ranchi district, Jharkhand. This report evaluated the feasibility of its use by ANMs only. Based on the results, it can be concluded that it is possible to implement the newly developed application. A total of 2500 cases were managed by ANMs using the application till May 2020. All ANMs used it to provide treatment to the children. 63% of ANMs used it to provide medications, 83% for counselling and 71% for follow-up as per the recommendations. The app is highly acceptable to ANMs for use as a clinical case management tool for childhood illness. There were some improvements in case management in both the age group (0-59 days and 2-12 months) of children. 78% of caregivers responded with their desire to revisit the health facility in future, highlighting the contribution of an e-tool in improving the perception of the caregiver.
