As the science of neonatology advanced over the latter part of the 20th century, neonatal intensive care units (NICUs) did become happier places, with fewer codes and deaths. But they were hardly peaceful, becoming busier, brighter, noisier and far more complex. With the risk of death receding for most babies, concern over the effect of these stressors on infant neurodevelopment, the NICU experience and satisfaction of their families, and the physical and emotional health of their caregivers has grown. One reaction to this concern has been the recent surge in construction of NICUs with most or all of their bed spaces in single-family rooms (SFRs).That SFRs may be better for babies directly by reducing exposure to noxious sensory stimuli and the risk of nosocomial infection, and indirectly by increasing skin-to-skin care through encouraging parental presence and intimacy are attractive hypotheses. Studies on adults in private room settings have demonstrated benefits, 1 but randomized controlled trials of these questions in newborns are difficult to undertake when the intervention involves construction of a multi-million dollar facility. Alternative strategies include the use of historical controls, or, in cases where 'hybrid' units exist (which combine both private and multi-bed rooms), concurrent controls, although these methods have obvious shortcomings.Assessing the satisfaction of parents and caregivers after moving from an 'open' NICU to an SFR NICU is a more accessible question. A previous study 2 as well as a large body of anecdotal information has demonstrated that families are more satisfied in private rooms, but are challenged by the isolation this setting imposes upon them. Caregivers, too, recognize that an SFR design improves the sensory environment for newborns and is more desirable for families, but creates communication and collaboration impediments for both families and staff that are not found in open, multi-bed rooms.
