Select Global Activities

Community-based kangaroo mother care to prevent newborn and infant mortality, Bangladesh: Four million newborns die each year, 99% in developing countries, 28% due to low birth weight (LBW) and prematurity and 26% to severe infections. Dr. Sloan was Principal Investigator (PI) of the first randomized controlled trial of Kangaroo Mother Care (KMC), a method whereby stabilized hospital-born LBW newborns are placed in skin-to-skin (STS) contact on the mother?s breast to promote thermal regulation, breastfeeding and maternal-infant bonding. The Ecuador study showed traditional KMC significantly reduces morbidity but not mortality as most newborn deaths occur before stabilization. With a multidisciplinary, multinational team, Dr. Sloan adapted KMC for immediate postnatal community-based (CKMC) implementation in rural Bangladesh where the incidence of home delivery is high and neonatal intensive care is virtually unavailable and is PI of a large randomized controlled trial to determine whether CKMC improves newborn and infant survival.
Misoprostol in the management of the third stage of labour, Gambia, The: Postpartum hemorrhage accounts for 25% of maternal deaths worldwide. While oxytocin is widely considered the best treatment for postpartum hemorrhage in the hospital setting, the availability of oxytocics (which require refrigeration and injection) is limited in rural areas of developing countries where home births are common. In these settings, misoprostol offers several advantages over oxytocin, including oral administration, long shelf life, stability at high temperature, no contra-indication for hypertensive patients, and it is inexpensive. Dr. Sloan was co-investigator of the first double-blind, community-based, randomized controlled trial to determine the impact of postpartum administration of oral misoprostol on PPH in a home birth setting in rural Gambia. As untreated hemorrhage can rapidly progress to death, the study was designed to address the need for a sustainable means of postpartum hemorrhage prevention in developing country settings where home births are common and transportation to referral hospitals limited.
Safe motherhood demonstration projects: Life saving skills (LSS) raining and emergency obstetric care (EmOC) health services improvements, Vietnam: As part of a multi-country evaluation of strategies to prevent maternal mortality, Dr. Sloan directed a large quasi-experimental evaluation in collaboration with the World Bank, Vietnamese Ministry of Health and Hung Vuong Hospital. The project evaluated the impact of LSS training and supply improvements in rural areas of Vietnam. The research led to national expansion of LSS training in Vietnam, and consequential improvement of EmOC services in the country.
