Development of the Couplet Care Bassinet

The current study is a Phase II evaluation of the Couplet Care bassinet, designed by Couplet Care Limited Liability Corporation (LLC), a novel infant clinical bassinet designed to support safe implementation of skin-to-skin contact and rooming-in on postnatal units. Until recently, the standard of hospital care for healthy term newborns was to be observed and cared for by maternity staff in a nursery with other infants. However, as detailed in the World Health Organization (WHO) / United Nations International Children's Emergency Fund (UNICEF) report Ten Steps for Successful Breastfeeding, it is now recommended that mothers and infants "room-in" together 24 hours per day, with one hour of separation allowable for procedures outside of the postnatal unit room. As a result, the practice of nursery care is no longer recommended nor facilitated. However, most bassinets in United States (U.S.) hospitals are still designed for use by ambulatory nursery staff, rather than by mobility-impaired new mothers. Current bassinets were not designed for patient use and restrict maternal access to the infants and introduce infants to increased risk of physical injury. Bassinet tubs can tip under the weight of mothers' arms and the height of the tub walls can compromise infant handling. Often, new mothers are required to either substantially twist the body to access the infant or get up out of bed to reach the infant, despite being in immediate postpartum period and needing to heal. Such actions can cause new mothers to experience unnecessary frustration, pain, or even injury. This is especially critical to the one-third of U.S. women who deliver by cesarean section, as the mother's limited ability to move and postpartum pain hinder timely and safe infant care, undermine breastfeeding, impede the mother's own recovery, and contribute to risk of infant falls and suffocation. The substantial difficulty maneuvering infants in and out of conventional bassinets, coupled with the pain and fatigue felt by new mothers, increase the risk of 1) infant drops, and 2) falling asleep with infants in unsafe arrangements. To address these gaps in safety Couplet Care has developed a novel bassinet that allows mothers to position infants over the mother's bed and handle the infants independently.

To ensure usability and safety, the Couplet Care bassinet design incorporates (1) a lower tub wall with access points, making it easier for a mother to reach her infant, (2) adjustability features that allow for bassinet positioning over the mother, and (3) a design that secures the tub into the frame.

In this phase of the project, the researchers will build on insights of Phase I to refine Couplet Care bassinet design, so it is manufacturable and compliant with Food and Drug Administration (FDA) regulations. Next, the Study Team component of the study will:

• Evaluate the impact of the Couplet Care bassinet on maternal-infant patient outcomes in a powered randomized controlled trial (RCT)
• Evaluate the usability and adoptability of the device from clinician perspectives. Successful accomplishment of this Phase II effort will position the Couplet Care bassinet for commercialization, delivering a bassinet that promotes safe mother-infant connection during rooming-in, while reducing the risk of infant drops/falls and suffocation, maternal waking from unmet infant needs, and demands on nurses for assistance for non-medical needs.
