Co-bedding, a developmental care practice for twins and multiples, has been theorized as a strategy to decrease the adverse neurodevelopmental effects that may be associated with hospitalization.


The aim of this study was to determine the feasibility of study design, methods, and the measurement of desired outcomes for the development of a larger multicentered study.


Study findings were used to estimate effect size, determine staff and bedside care organization, evaluate feasibility of data collection measures, and identify issues related to recruitment and follow-up. Results were incorporated in the development of a larger multicentered trial grant proposal.


Pilot studies can play an important role in the development of a competitive grant proposal and efficient conduct of a research trial. Pilot studies strengthen a proposal by providing essential baseline information. A general overview of the purpose of pilot studies is provided here, along with a description of the process of using findings from a pilot study to inform the development of a larger multisite trial. Findings from this pilot study examining the effects of co-bedding on twins and their parents are used to revise the research protocol for a larger multisite trial. These changes, which lead to improvement to the protocol, and the rational for these changes are highlighted.
