Enhancing the Survival of Low Birth Weight Infants in Low-Resource Settings

Globally, about 20 million infants are born with low birthweight (LBW), and these infants face a myriad of health challenges, including difficulties in regulating body temperature, poor nutritional status, increased vulnerability to infections, and delayed development, placing emotional and financial burdens on families. Kangaroo Care (KC), consisting of continuous skin-to-skin contact, exclusive breastfeeding, and early discharge, is an evidence-based intervention recommended for LBW newborns to improve their survival and healthy development, especially in low-resource settings where the risks of prematurity, neonatal hypothermia, and neonatal mortality are disproportionately high. Despite the effectiveness of KC, widespread scale-up has been slow due to barriers to implementation and adoption. Existing efforts have primarily focused on health systems and policy changes, neglecting the need to support mothers and families to continue practicing KC at home. Several sociocultural and economic factors, including lack of essential warmth-related items, cultural norms, stigma, and limited social support, hinder the KC continuation at home. To address these challenges, an intervention grounded in the Information, Motivation, and Behavior (IMB) model has been developed. The intervention offers emotional, informational, and motivational peer support to mothers of LBW infants and a kit containing low-cost, locally sourced neonatal care items to facilitate skin-to-skin contact and breastfeeding. A type II hybrid effectiveness-implementation study will be conducted. First, the effectiveness of the intervention will be tested using an individual randomized controlled trial, enrolling 328 mother-infant dyads eligible for KC from two tertiary hospitals in Ghana (Aim 1). It is hypothesized that mothers receiving the intervention will be more likely to continue KC at home 7 days after discharge compared to those in the control group receiving the standard of care. The primary effectiveness outcome is any duration of skin-to-skin contact and exclusive breastfeeding at 7 and 28 days post-discharge. Second, the implementation process including associated barriers and facilitators to implementation will be explored using mixed methods (Aim 2). In-depth interviews will be conducted with participants, peer supporters and healthcare workers. Thematic analysis of the interviews will be guided by the Consolidated Framework for Implementation Research (CFIR) framework and combine both inductive and deductive approaches. Findings from this research will inform the development of effective models for KC implementation and scale-up.
